How to connect the wires : Practical Tips with photos

wire connection problem at least once in his life occurred in each person.Furthermore, this production is presented in a rather wide assortment: aluminum and copper, single-core or multi-conductor, computer and telephone, power and heating.They are designed for different loads and require special approaches to work.The question arises: how to properly connect the wires?

main requirement to secure insulation and long service life is ensured.

Features compounds aluminum and copper wires

Traditional twist is not always able to provide the desired result.Especially in the case of compounds of copper and aluminum wire.

As a result, after a number of cycles of heating and cooling contact will weaken so much that can overheat and disconnection.Such a situation is unacceptable in terms of safety.

there are a few basic types of devices for connecting wires:

• Connection insulating clamps;
• Screw terminals and junction boxes or pad;
• Self-clamping terminals and hubs;
• Clamping hubs;
• Connectors with IDC;
• connectors connectors and terminals.

their practical application requires different approaches and tools.

Connection insulating clips

Connection insulating clamps or simply caps PPE provide simultaneous isolation and exposure lock.It is used exclusively for solid wires.

Before you connect the wires, the ends are twisted in a clockwise direction.Inside the cap has a helical spring, compressing the wires as donning.Clamp is screwed onto the contact place also in a clockwise direction.

Screw terminals and junction boxes

Screw terminals used to connect copper wires.Aluminum is quite soft and flexible material.At constant pressure, it deforms.As a result, the contact will weaken and begin to warm up with the times.

In practice, the wire is inserted into a brass sleeve and clamped screw terminal block.For secure connections at each section of wire is necessary to select the size of the openings devices.

Note that if too much force can break the brass sleeve.

In screw junction box contact also been clamped by means of screws.It is suitable for joining aluminum and stranded wires.This is possible thanks to some structural differences from the pad terminals.The end of the wire is clamped between two plates.The upper has a surface that allows to increase the contact surface.

Self-clamping terminals and splitters

Self-clamping terminals and splitters designed to connect only solid wires made of copper or aluminum.They can securely connect two of these materials with each other.This is a disposable product.Their design includes a pressure plate which provides intimate contact with the bus wire ends tinned copper compound and does not diminish with time.

question arises: how to connect the aluminum wire with the help of this device?On the surface of the pressure plate is applied a mixture of silica sand with petroleum jelly.

first is abrasive to remove the oxide film from the aluminum wire, and the second - to prevent it from re-education.For reliable and long service life of products is necessary to comply with the requirement on the maximum design value of current passed through it.

Clamping hubs for correct wiring

Clamping splitters suitable for any kind of wires in any combination.The product design includes a plate, which presses the end of the wire to the bus of tinned copper.

Unlike cleat terminals, the compound reusable.A reliable contact is ensured by a special movable lever.It allows you to change the wires and an unlimited number of combinations.The product is designed for maximum power of 35A current.

Connectors with IDC

Connectors with IDC or scotch LokaIt can only be used in networks with weak load.For example, phones or LED lamps.This is a one-off product.

The design includes one or two plates, one surface of which is a cutting-clamping.The interior space is filled with hydrophobic gel connector.Its purpose - to protect the place from the contact oxidation, moisture and corrosion.

When using wires are inserted into the holes and tape-lock snaps compressive force.Plate cuts the wire insulation and ensures a tight connection.

connecting sleeves for wire high current

connecting sleeve used for high currents.Suitable for aluminum and copper conductors, or combinations thereof.Using fairly simple.

One or more wires are placed inside the sleeve, and she clamped special pliers.Application tool provides a quality connection, which does not require additional maintenance.There are several types of products:

1. to connect the wires to the body when the earth using the sleeve with a flat end and a hole in it;
2. For solid wires used cartridge with screw connection;
3. for any combination of wires used universal sleeve of tinned copper.

Tip designed to securely connect stranded copper wire.On the one hand it has an extension.Before you connect the copper wire, the ends have to twist and insert the expansion.Then tip pressurized clamping pliers.The thus treated further end of the wire can be used in any type of compound.

main goal pursued by using various means to connect the wires - providing them with a reliable and prolonged contact.Knowledge about the purpose and features of the product design will help maximize the use of them in practice.
