Connecting cable VG with each other. Types of connecting electrical wires in a dispenser box. Scotch Loki, Scotchlok, Electric Connector with Mortise Contact

Very often, users on the forums are looking for information about the connection of two computers to the local network. We ask a similar question not only to the forum participants, but also on sites where the so-called FAQ is implemented (question-answer). Since the connection of computers through the LAN cable also calls questions and at blog visitors, I decided to write a detailed article instruction. It should be said that in this publication, we will consider the connection of two computers to the LAN cable network, and Wi-Fi Wirelessly Consider in one of the following publications.

As you understand for the local connection of two computers, we need a LAN cable compressed by the cross way. It is worth saying that for computers with an Ethernet AUTO-MDIX interface (interface dependent on the transmission medium), the processing type (direct or cross) does not matter because the network port is automatically configured. This technology must be supported by two devices.

Nothing perfectly and in practice it happens that network punctures with Ethernet Auto-MDIX refuse to work correctly. In order to avoid such situations, we recommend that you adhere to the standards of crimping the vita pair and each type of Pressing LAN to use for its intended purpose. Before connecting two computers to the local network, make sure that you use the working and the desired cable type. In detail about where the straight and cross-type is used and how to make the LAN cable without crymenter (crimping tool).

The length of the twisted pair for connecting two computers to the local network should not be more than 100 meters. Otherwise, the attenuation of the signal will reflect on the quality of the network.

In addition, you can use FireWire (IEEE 1394 or i-Link) Cable for connecting two computers if both devices (Laptop, Desktop) have appropriate ports. If IEEE 1394 ports are not, you can install in the Desktop FireWire / extension controller / extension board for PCI slot, and put the PCMCIA card with i-link ports in the laptop. FireWire cable have an execution of 4 contacts (PIN) and 6 contacts (PIN). Depending on the available ports in the connected computers, use the appropriate cable.

So, you connected two computers in one of the method described above. If you create a network connection of two computers via the RJ-45 connector, the Ethernet light indicator indicator should shine / flash green (as a rule, the light indicator is located near the RJ-45 connector). If this does not happen or the indicator glows only from one computer, then check the correctness of the crimping cable.

Also make sure that the network adapters are enabled, the drivers for them are installed and the devices are operating normally. But if the indicators on two computers are glowing or blinking, then it follows from this that the hardware connection is installed and the cable does not have breaks and works correctly.

If you are using the Windows 7 operating system (Windows XP), then as a rule, after connecting, the computers begin to "see" each other and work normally. It all depends on the preset parameters. However, if this did not happen, you need to make some changes to the network connections.

Let's look at the direct connection of two computers via the FireWire or LAN cable (twisted pair) by controlling the Windows XP operating system, and then we will analyze how to merge two computers running on Windows 7. It is desirable that two connected computers are in the same workgroup.

Connection of two computers to the network running Windows XP.

Enter the "Start" to the "Control Panel" and click the Network Connections icon. Right-click on the "Connection on the LAN" and in the context menu, enter the properties.

In the window that opens, go to the "Internet protocol (TCP / IP)" and stop the switch to the "Use the following IP address" position.

Here we need to enter a network IP address for a computer. For example, so:

IP address: 192.168.1.1
Subnet mask: 255.255.255.0
Main gateway: 192.168.1.0 (Enter if computers do not see each other)

You do not necessarily type "Main Gateway", but if computers do not see each other, then enter this parameter. After that, in all windows, press "OK".

You need to do the same on another computer, but enter another IP address. For example, so:

IP address: 192.168.1.2
Subnet mask: 255.255.255.0
Main gateway: 192.168.1.0 (you should enter if there are no connections)

Now the connection must be established between computers (if there is no connection between the personal staff, then reboot them). To make sure the settings are correct, log in to "Network Connections" and click on the "Local Connection" icon. In the "Status" window should be "connected".

If it is limited to "Connection limited", then check the correctness of the network connection settings. With the connection in the Windows XP operating system, we figured out, now let's look at how to organize a network between two computers in Windows 7.

Connection of two computers to the network running on Windows 7.

Actually, in Windows 7, there are no special differences to communicate two computers in a network of special differences, but to be clear to those who use this particular operating system, I will describe a sequence of actions specifically for them.

We go to the "Start" in the "control panel" and select "Network and the Internet". Next, go to the "Center and network management and common access" and click on changing the parameters of the adapter. Here we are in place. Click on "Connecting over the LAN" with the right mouse button and go to "Properties".

Now go to "Internet version 4 (TCP / IPv4)" protocol and switch the button to "Use the following IP address". Next, you need to enter network settings.

The main gateway makes sense to enter if there is no connection between computers. For example, so:

IP address: 192.168.1.7
Subnet mask: 255.255.255.0
Main Gateway: 192.168.1.0 (Enter if there is no connection)

You can set any other parameters for the IP address, the main thing is to be in the range from 192.168.1.1 to 192.168.1.254.

On the second computer you need to enter exactly the same parameters and change the latest digit in the IP address. For example, so:

IP address: 192.168.1.8
Subnet mask: 255.255.255.0
Main gateway: 192.168.1.0 (register in case of no connection)

After you specify the necessary parameters, do not forget to press the "OK" button in all windows. If there is no connection, restart computers. To make sure that everything works correctly need to check the connection between computers. To do this, on one of two computers, open the command prompt. Enter the "Start" and in the search field with the signature "Find Programs and Files" enter CMD.

For example, to check the connection on a computer with IP 192.168.1.7 parameters, we write the Ping team 192.168.1.8 and press the Enter key.

A positive result will be the result shown in the image. If sent \u003d 4, obtained \u003d 4, losses \u003d 0, then everything is configured correctly. The connection of two computers is directly executed.

Now you can share files between computers to exchange files. Until!

Not quite understood your question. Why should something fly? Or do you mean you need to change network settings? For example, to connect to the Internet.

There is nothing better than after the end of the next hard working day to go to the virtual game world, recreated on the computer screen to shoot a careless monster. It is not only interesting, but also useful. True, to boom gaming spaces are not in proud loneliness, but together with a comrade for arms, you have to figure out how to connect two computers with each other. There is an opinion that unrealized internal tension provokes conflicts and disorders in families. The inhabitants of the rising sun are so "penetrated" by this idea that they even offer everyone for a small amount to beat the plates about the concrete wall in the equipped rooms or arrange bats with pillows. What is called - to the last flip.

Combining computing power

The question of how to connect two computers with each other, has come yesterday. As early as the first XT machines, the owners often had to deal with how to directly exchange data without intermediate carriers. And, it is necessary to admit, the task was very successfully solved. The modern systems in their capabilities have exceeded their predecessors. In this article, we will tell about the most popular ways of communication and point out how to connect two computers with each other in practice.

Serial port

One of the easiest ways to check the time is to combine two computers to the network by connecting their COM connectors using a zero-modem cord. Not all modern motherboards are completed with this port, but if it is, then you can say, lucky. If only because you can not only not "break your head" above how to connect two computers with each other, but also easy to connect a programmer, oscilloscope or satellite tuner for firmware. In a word, if the COM port is, it is the advantage of this system.

You can buy the cord both to buy and make it yourself. In the latter case, you will need a three-core wire (up to 18 m) and two DB-9F sockets. You need to connect according to the circuit "2 and 3, 3, and 2, 5 and 5", and also do not forget to close on each "7-8" to remove the ban on the transfer. Speed \u200b\u200babout 8 cbv. A more complex implementation uses already 7 conductors and is capable of working for 115 cbv.

Network via com

This connection is called direct and does not require any special drivers. Connect the cable to completely de-energized system blocks. Each of the computers need to open the Control Panel window and start creating a new connection in the network section. Next, you need to select the creation of direct connection to the second computer. When requesting on one machine, you must specify the "presenter", and on the other - the "slave". You will also need to come up with a name, password of access and method - "through the COM port". If everything is done correctly, a new one will appear in the list of connections - in its properties you need to select the "Connect" command. Although, of course, this method has restrictions and it cannot be recommended for permanent use. More preferred options.

Local network Ethernet

Each modern motherboard necessarily there is a built-in network card. Her connector resembles the usual telephone, with the only difference that is a bit bigger on the dimensions. How to connect two computers with each other on windows 7 using the specified cards? Perhaps this is the easiest way. True, requiring the purchase of a "twisted pair" cable and physical connection of system units with it.

Two conditions that must be completed on both computers are allowed to use Ethernet, drivers are installed in the operating system. For speeds of up to 100 Mbps, the length of the line is permissible to 130 meters, but the gigabit network operates at smaller distances.

So, one of the cable forks needs to be connected to the first computer connector, and the other is the second. Next, you need to proceed to the "Control Panel", from there - to the Network Management section and use the item to change additional access parameters where you want to enable network detection and, if necessary, joint access to resources. For trusted networks it is useful to abandon passwords - it will accelerate work.

Radio communication

An excellent alternative is a wireless connection. In how to connect two computers with each other through WiFi, there is nothing complicated. Especially if you need to organize the connection of two laptops, in which there are already WLAN modules. In the staff, these components will have to buy.

First, on the first you need to go to "Network Management", select a link that is responsible for setting up a new connection, and specify the "Configuring Computer Network Setup" item. Next, you will need to come up with a name, encryption method and password. The properties of the network adapter will need to go to "Protocol version 4" and register IP 192.168.0.2. The last thing to be done is to allow detection, as stated earlier.

On the second computer, the latter in this window the figure should differ. After that, you need to use the network search function in the system tray, select the desired name and enter the access code.

How to connect two computers with each other through the router

The main condition - the name of the network must coincide. This can be done in My Computer - Properties - Advanced System Settings - Change. For example, home. Next, in the Network Management section of both systems, you need to select the type "home network", and in the list on the right - "willingness to create". A window will open, which requires the creation of a home group, with which you need to agree. It will remain allowing Windows to control the connections of the working group and disable password access. That's all. After rebooting, you can scan the network - the target computers will be displayed there. Additionally, on each of them, you can subsequently open access to resources (drive, hard drive, etc.). Actually, this is a kind of previous way. The only difference is that a router comes in the role of one WLAN adapter.

The most important elements of any electrical network are points of connecting wires. The reliability and durability of the electrical network depends on the quality and correctness of these works. Unfortunately, such poor-quality works can not be diagnosed, the disadvantages are manifested when the system loads. At the same time, a poor quality is started to warm up and this often leads to a fire, which is not always able to localize.

This review describes the main types of wire connections with photos, their classification and application.

Regulatory documents

There are many ways to connect wires. Their use or prohibition is regulated by the current rules of the electrical installation devices (PUE), which approves the Ministry of Energy of the Russian Federation. They should not contradict the current document.

The regulatory framework over time is adjusted, since there is a steady increase in electricity consumption and some types of compounds do not provide the necessary reliability in modern conditions. For example, in accordance with current rules, it is impossible to use a twist without additional fixation, which has been widely used before, as there are better and no less affordable modern technologies.

In order to determine how it is better to connect wires, it is necessary to study all available technologies, determine their advantages and disadvantages. First of all, they are classified as necessary for additional skills for work. Do not require their fastening using terminals, various spring clamps, bolts and caps of PPE.

Each solution has its advantages and disadvantages. First of all, they differ in the simplicity and reliability of the installation. In general, it can be said that quickly performed contacts with the use of various terminals and clamps can weaken over time and lead to accidents. High-quality contacts made using sleeves, soldering or welding require more time and are not subjected to disassembly.

Thus, reliability is directly proportional to the complexity. Before connecting the wires with your own hands, you should familiarize yourself with the instructions. It is worth noting that in all the works it requires preliminary cleaning of materials from an oxide film.

Specifications of various options

Let us consider creating additional tools in more detail. They allow you to get reliable connections designed for large currents.

Soldering

This type of electrical wire connection is widespread. Most often it is used for copper conductors. For this you need a soldering iron, tin and rosin. The sting is wetted by a small amount of molten solder, which is then transferred to a twist when it is heated. The remains of rosin evaporate when warming up. Before soldering a few lived, it makes sense to raise each of them separately.

Such solutions are very conveniently used for the conductors of a small diameter, both single-core, and with a large number lived. Work should be performed as quickly as possible not to melt plastic isolation. In this way, aluminum can be connected, but this requires a special flux and solder.

Welding

Welding withstands large currents and has mechanical strength. You can join both copper and aluminum. It is very convenient for lived a large diameter. They are twisted into one bundle, and using the welding machine through it is passed the high current, which melts the metal at the end of the twist.

In order to get a neat contact, you must first take off and select the parameters of the welding equipment. This can be done using unnecessary trimming. It is necessary to melt metal without damaging isolation.

Pressing

Covering is performed using a sleeve and a special tool. They are made of copper and aluminum. This operation is quite simple, but requires the selection of the sleeves of the desired size and a special tool for their compression.

Works are performed quite simple: the veins are folded into the beam, are inserted into the sleeve and crimped in several places. It can withstand thumb. The greatest difficulty consists in selection of the sleeves of the desired diameter: they should not be too large or small.

Twist

As described above, this method cannot be used without additional fixation. Since it does not allow you to create reliable contact. A twist is used in combination with soldering, welding, crimping or use of PPE. Before fixing the wires exposed to a twist.

The described three methods involve their subsequent electrical insulation. To do this, use an insulating tape for electrical installation works or heat shrink tubes. They are made of polymer material, which allows when heated to reduce their diameter several times.

Products produced various nomenclature. First of all, it is necessary to allocate the need to use outside the premises of light-resistant materials. For shrinkage, it is best to use an industrial hairdryer or gently warm the polymer pipe with a soldering iron.

For reliability, after installing the first tube, mount the second diameter tube. After shrinkage, the material must reliably close the ends of the contact.

The following solutions do not require additional snap and allow you to easily perform the correct connection of the wires at the initial level of qualifications.

Terminal blocks

Previously, they were widely used, thanks to their cheapness and reliability. It can connect wires of different sections. They can be copper or aluminum, can consist of one or many lived. They are clamping with screws on the contact block.

The disadvantage is that they are connected only in pairs. For a larger number of connections, special jumpers are required. There are other options for easier connection.

Connecting insulating clamps

One of them is the use of SIZ caps. This is a plastic cap within which the spring is installed from the metal. It cools on a bundle, twisting them, plastic serves as electrical insulation. Such contact is very reliable. There is a domestic development of the company KZT, which dresses directly to the twist.

Wago clamps

This type of connection conquered the market for convenience and simplicity. They connect all sorts of conductors. Clamps are produced on various number of connections.

The disadvantage is that the design has a spring, which can weaken over time, which can lead to an accident and ignition. Therefore, only original, branded products should be purchased.

Bolted fasteners

This type of fastening is classic, allows you to connect copper with aluminum. Consists of a bolt with a nut and three washers. It can be made independently in the absence of other connectors.

Conclusion

The choice of how best to connect wires depends on their type, budget and time. If you follow PUE rules, you can perform safe and reliable contacts that will serve for many years. It should be remembered that in any case, these works must be performed as neat as possible and cautively, without a rush.

Photo process connection process

Looking for a way of sharing files between two computers using a LAN cable (LAN cable)? Well, congratulations, your search finally ends on this site. I am sure that this small instruction will help thousands of people who want to transmit files from a PC to a PC using an Ethernet cable. I am sure that this article will be useful for you. So, let's begin.

Before you start, you need to know that sharing or transferring files from a computer to a computer by connecting them using an Ethernet cable is one of the most vintage methods. Over the past years, Wi-Fi technology has developed significantly, and while your two systems are in one local network, you can simply enable sharing on one PC and use another computer to access these files.

When you need to use a local network cable to send files from one computer to another?

Oh, this tedious thing when you need to connect thousands of flash drives when you want to save some data, and it also takes a lot of time. If you are tired of you, then you will fit this way of connecting computers! This method is also useful when, for example, computers are not connected to a common Wi-Fi router or one does not have a permanent connection to such a network.

Moreover, you can also use this method when you need to transfer many data, such as your collection of multimedia, from one PC to another. Believe me if you do not have enough Wi-Fi settings and network settings to use full speed, moving multimedia files by several hundred gigabytes via WiFi is not the best idea. I tried to do it, and it really, hell!

Advantages of connecting two computers via LAN

The main advantage of the transmission via an Ethernet cable is that it is very fast, at least faster than the usual WiFi transmission. If you have a lot of data for transmission, it is best to use an Ethernet cable.

What Windows tested?

This method is tested on Win 7, 8, 10, i.e. On those one of which is probably installed with you. Therefore, you can not worry about that it will not work.

What should I have?

2 computers with Windows.
1 LAN cable.
A little time and patience (only if you do it for the first time).

Data exchange between 2 computers via LAN cable

Step 1

Connect both computers to the local network cable.

Step 2.

Well, now you must configure the sharing parameters on both computers.

Go to the control panel in the Start menu and open it. Scroll through the path "Network and the Internet\u003e Network and Shared Access Center\u003e Change Additional Shared Parameters":

Here, select the "Enable Network Detection" option in the sharing section of the folders. Now select the "Disconnect password-protected" option. Thus, you will not need to enter the password every time you are trying to access the shared folders from another computer. However, it is also a significant risk to security. Therefore, make sure that you have selected "enable password secure access", as soon as you finish the transfer of files through the Ethernet cable:

Step 3.

Now we have to connect both computers to the same network.

Open the Control Panel\u003e Network Management Center and Sharing:

You will see a local network connection or Ethernet. Click on the link "Local Network" link:

In the dialog box that appears, click on the "Properties" button:

Find and select the Internet version 4 (TCP / IP V4) protocol in the list and click the Properties button:

In the Properties window, select the "Use the following IP address" option. Now add the following values \u200b\u200bto the fields for the first computer and save the changes:

IP address: 192.168.1.1
Subnet mask: 255.255.255.0
Main gate: 192.168.1.2

On the second computer, do the same in the IPv4 properties window and enter the following values \u200b\u200band save the changes:

IP address: 192.168.1.2
Subnet mask: 255.255.255.0
Main gate: 192.168.1.1

In fact, we are simply manually prescribed different IP addresses for two computers and make each other's basic gateways for them.

If everything works correctly, you will see the names of two computers in the "Network" panel.

Step 4.

At this step, it is assumed that you correctly connected the cable, included the shared access parameters and configured the IP addresses, now it's time to send files from one computer to another. To do this, you first need to open access to the target folder on the local network.

All electrical engineering, from the time of Faraday, uses wires. And so many years, how many wires are used, the problem of their connections are facing electrical atomers. What are the ways to connect conductors, this article tells about the advantages and disadvantages of these methods.

Job connection

The easiest way to connect the wires is a twist. Previously, it was the most common way, especially when conducting wiring in a residential building. Now, according to PUE, the connection of the wires is prohibited in this way. The twist must be sued, brew or put. However, these methods of connecting wires begins with a twist.

In order to perform a high-quality twist, the wires connected must be cleaned of isolation to the required length. It ranges from 5 mm when connecting wires in headphones up to 50 mm, if it is necessary to connect the wires with a cross section of 2.5 mm². Thicker twist wires are usually not connected due to a lot of rigidity.

The wires are cleaned with a sharp knife, ticks for removing isolation (KSI) or, after heating with a soldering iron or lighter, isolation is easily removed by pliers or side. For better contact, the bare sections are cleaned with sandpaper. If the twist is supposed to be disappeared, then the wires are better to post. Wired wires only with rosin and similar fluxes. This can not be done - it corps the wire and she begins to break at the site of the soldering. Even the wash places in the soda solution is poorly helped. Acid couples enter insulation and destroy metal.

The stripped ends fold in parallel, in one bundle. The ends are aligned together, tightly keeps the hand for an insulated part and the entire beam is twisted with pliers. After that, the twist is disappeared or welded.

If there is a need to connect the wires to increase the total length, they are on each other. The stripped areas are superimposed cross-closer on each other, dried together with their hands and tightly chewed with two pliers.

You can twist only wire from one metal (copper with copper, and aluminum with aluminum) and one cross section. A twist from the wires of different sections will be uneven and will not provide good contact and mechanical strength. Even if it is suited or put it, these types of wire connects will not provide good contact.

How to connect soldering electrical wires

The connection of electrical wires soldering is very reliable. You can discourage the unchanged wires, but such a soldering will be fragile due to the fact that the solder is very soft metal. In addition, it is very difficult to lay two conductors in parallel to each other, especially on the weight. And if you solder on some reason, the rosin sticks the place of soldering to it.

A layer of rosin is applied to pre-listed and twisted conductors. When using another flux, it is applied to the appropriate way. The power of the soldering iron is selected based on the cross section of the wire - from 15 watts when soldering headphones up to 100 W screws of a twist from wires with a cross section of 2.5 mm². After applying a flux, a soldering iron is applied to a twist and warms up to a complete melting of the solder and pushing it inside the twist.

After cooling the soldering, it is insulated with a tape or it is put on a slice of a heat shrink tube and heated with a hairdryer, a lighter or a soldering iron. When using a lighter or soldering iron, care must be taken and not to cut the heat shrink.

This method reliably connects wires, but is suitable only for thin, no more than 0.5 mm² or flexible up to 2.5 mm².

How to connect headphone wires

Sometimes serviceable headphones have a cable near the plug, but there is a plug from faulty headphones. There are also other situations in which the connection of wires in headphones are needed.

For this you need:

crop the broken plug or unevenly torn cable;
clean the external isolation by 15-20 mm;
determine which of the internal wires is general and check the integrity of all conductors;
crop internal wiring according to the principle: one does not touch, shared by 5 mm and the second is 10 mm. This is done to reduce the thickness of the connection. General conductors can be two - for each headphone. In this case, they are twisted together. Sometimes the screen is used as a common conductor;
clean the ends of the wires. If the lacquer is used as insulation, it will burn in the process of the mezzani;
load ends for a length of 5 mm;
to put on a piece of a 30 mm long heat shrink tube longer than the expected length of the connection;
to put on the long ends to wear pieces of a thinner shrink tube with a length of 10 mm, on the average (general) not to wear;
twist wiring (long with short, and medium with average);
drink twists;
bend the leaning twist, to the unprotected edges, to drive out pieces of thin shrink tube on them and warm it with a hairdryer or lighter;
start the connection to the connection with a larger diameter and heat the heat shrink tube.

If everything was done carefully, and the color of the tube is picking up the color of the cable, the connection is unnoticed and the headphones will not work worse than new ones.

How to brew scruit

For good contact, the twist can be boiled with a graphite electrode or gas burner. Welding the burner did not get distribution due to the complexity and the need to use gas cylinders and oxygen, so in this article only about electrical welding.

Electric welding is made using a graphite or coal electrode. Graphite electrode is preferable. It is cheaper and provides better welding quality. Instead of purchased electrode, you can use a rod from a battery or a brush from the electric motor. Copper electrodes are better not to use. They often stick.

For welding you first need to make a twist with a length of 100 mm so that it is ready for about 50. Speakers need to end. For welding it is best to use an inverter welding machine with an adjustable current. If there is no such, then you can take the usual transformer with no less than 600 W and voltage 12-24 V.

Near the insulation using a thick copper clamp, "Mass" or "minus" is connected. If you just wind the wire on a twist, then the twist will overheat and melts insulation.

Before starting welding, it is necessary to choose a current. The required current varies depending on the amount and thickness of the wire, which consists of a twist. The duration of welding must be no more than 2 seconds. If necessary, welding can be repeated. If everything was done correctly, a neat ball appears on the end of the twist, shipped to all wires.

How to connect the wires of crimping

Another way to connect wires is a pressing. This is a method in which a copper or aluminum sleeve is dressed on the connected wires or cables, after which it is pressed by a special press. For thin sleeves, a manual prescription is used, and for thick hydraulic. In this way, you can even connect copper and aluminum wires, which is unacceptable with a bolted joint.

To connect this method, the cable is cleaned longer than the length of the sleeve, so that after dressing the sleeve, the wire looked out by 10-15 mm. If thin conductors are connected with crimping, then you can pre-make a twist. If the cable of a large cross section, then, on the contrary, on the stripped areas it is necessary to align the wire, fold all the cable together and give them a round shape. Depending on the local cable conditions, you can fold the ends in one direction or counter. This does not affect the reliability of the connection.

A sleeve is tightly dressed on the prepared cable or, with the oncoming laying, the wires are inserted into the sleeve on both sides. If the sleeve remains free place, it is filled with slices of copper or aluminum wire. And if the cable is not placed in the sleeve, then several wires (5-7%) can be bought off by side. In the absence of a sleeve of the desired size, you can take the tip for the cable, scuffing from it the flat part.

The sleeve is pressed 2-3 times in length. Pressure testing should not be at the edges of the sleeve. From them it is necessary to retreat 7-10 mm so that with crimping it is not crushing the wire.

The advantage of this method is that it allows you to connect the wires of different sections and from different materials, which is difficult at other connection methods.

A sufficiently common method of compound is a bolted connection. For this species, a bolt is needed, not less than two washers and nut. The diameter of the bolt depends on the thickness of the wire. It should be such that the ring can be made from the wire. If the wires of different sections are connected, the bolt is selected large.

To carry out the bolted connection, the end is cleared of isolation. The length of the stripped part should be such to make the round-roll ring dressing on the bolt. If the wire is stranded (flexible), then the length should allow after making the ring to wrap the free end around the wire near the isolation.

In this way, you can connect only two identical wires. If they are more, or different in cross-section, rigidity and materials (copper and aluminum), then it is necessary to lay the conductive, usually steel washers. If you take a bolt of sufficient length, then any number of wires can be connected.

Connection terminalnik

The development of the bolted compound is terminal. Terminals are two species - with a clamping rectangular washer and round. When using a clerk with a clamping washer, insulation is removed for a length equal to half the width of the terminal bar. The bolt is released, the wire fit under the washer and the bolt is prescable again. On the one hand, only two wires can be connected, preferably the same section and only flexible or only one-core.

Connecting to a terminal with a round washer does not differ from the use of a bolted connection.

The connection of the wires is obtained reliable, but bulky. When the wires are sodium, more than 16 mm² the connection is unreliable or it is necessary to use tips.

Self-armed Terminals Wago.

In addition to terminals with bolts there are also terminals with clamps. They are more expensive than usual, but allow you to have a connection much faster, especially in connection with the new requirements of PUE and ban on twist.

The most famous manufacturer of such Terminals company WAGO. Each terminal is a separate device with multiple holes for connecting wires, each of which is inserted separate wire. Depending on the execution connects from 2 to 8 conductors. Some types are filled in inside conductive paste for better contact.

They are available for both the ones and in detrimental connections.

In the terminals for an indefinite connection, the stripped wire is simply inserted and the spring mustache fix the wire inside. Wire can only be used hard (single-core).

In terminals for the terminal connection, the wire is clamped using a folding lever and spring clamp, allowing you to easily connect and disconnect the wires.

Since the wires do not come into contact with each other, the terminals allow you to combine the wires of different sections, one-core with stranded, copper with aluminum.

Best of all, this method of connecting the conductors showed itself with small currents and received the greatest distribution in lighting networks. These terminals are small and easily placed in transition boxes.

How to connect electrical wires tips

Another way is to use tips. The tip is similar to a piece of tube, cut and deployed in a plane on one side. A bolt hole drilled in the flat part. Tips allow you to connect cables of any diameter in any combination. If necessary, combine the copper cable with aluminum use special tips, in which one is copper, and the other aluminum. A variant is also possible, in which the washer, brass or copper muddle is laid between the tips.

The tip is painted on the cable using the mapping player, similar to how the wires are connected using crimping.

Soldering tips

Another way to use the tip is to solder it. For this you need:

sliced \u200b\u200bcopper cable;
tip, calculated for soldering. It is distinguished by a hole near the flat part and a thinner wall;
bath with molten tin;
bank with orthophosphoric acid;
bank with a solution of soda.

Caution! Work in protective glasses and gloves!

In order to solder the tip, the cable is cleaned by the length of the tubular part of the insulation and is inserted into the tip. Then the tip is sequentially immersed in orthophosphoric acid, in the molten tin for a time sufficient to bundled the acid and pushing the solder in the tip. This is checked by periodic short-term removal from solder. After the impregnation of the tip and cable, the tip is descended into the soda solution. This is done to neutralize acid residues. The cooled tip is washed with clean water and is ready for further work. Such a tip can be connected to aluminum tires and tips without the use of transient washers.

Connectors for cables and wires

Cable can also be connected by special connectors. These are segments of pipes in which the thread is cut and the bolts are screwed. Connectors are disconnected, in which the bolts are twisted and indefinite. In the indefinite connectors, the bolts head are broken after clamping. There are also connectors designed to connect wires and cables of different sections. The cable to the connectors are inserted to the online approach, towards each other.

The connectors used on the power lines of power lines consist of two halves connecting bolts. The wires are stacked in special grooves towards each other, after which both halves are clamped with bolts.

Compound live wires and cables using couplings

If the connected cable is in the ground, water or in the rain, then the usual methods of isolated connection are not suitable. Even if we apply a layer of silicone sealant on the cable and clipped with a shrink tube, it will not give a guarantee of tightness. Therefore, it is necessary to use special couplings.

The couplings are in the plastic and metallic case, fuel and heat-coated, high-voltage and low-voltage, conventional and small. The clutch selection depends on the specific operating conditions and the presence or absence of mechanical loads.

Connecting wires and cables, this is one of the most important points during the electrical installation. Therefore, all methods for connecting electrical wires should provide good contact. Bad contact or bad insulation can lead to short circuit and fire.
