With a crimping tool or crimping tool, a solid conductor or a fine or stranded conductor can be prepared for a clamping connection. In particular, the focus is on the crimping of insulated or uninsulated wire end ferrules, but also shock connectors, pin cable lugs, fork and ring cable lugs or flat receptacles can be connected with it. There is also a special one Western plug crimping tool or one for coax connections. The Crimping pliers offer is confusing and not easy for the layman to see through. So you at the Buy crimping tool keep track, we have this Crimping tool comparison from Test-Vergleiche.com with the most important distinguishing features for you so that such a tool will soon also be in yours Toolbox Takes place.

What is a crimping tool?

The crimping tool, also called wire crimper or crimping tool, is an important tool for the electrician. With her hard detachable connections between a conductor and a connecting element are produced, which is thus mechanically firmly connected and allows an electrical connection. With the crimping tool, the individual wires of a cable are permanently connected with, for example, a wire end ferrule.

Anyone who has ever tried to accommodate individual stranded wires, for example in a luster terminal, knows the problem: some of the fine wires get lost and protrude. Others say goodbye when turning the screw. All this is at the expense of safety, not to mention that it is inadmissible. This is remedied by end sleeves, which are slipped over the wires and pressed.

Who else? Crimping tool experience will know that quite a lot of force has to be spent on pressing. For this reason, many models are equipped with a so-called toggle, since the power of one hand is usually not sufficient to achieve a permanent deformation.

In the field of telecommunications technology is crimped almost exclusively, as this method provides a high connection security and easy to use. The pressure exerted must be exactly matched to the conductor and the connection part.

What are connecting elements for the crimping tool?

Almost all fasteners for the crimping pliers are isolated and uninsulated. For example, there is one Crimping pliers for uninsulated cable lugs or another for insulated or uninsulated wire end ferrules. What you can crimp everything, you can see here:

• ferrules
• Twin ferrules
• Blade receptacles and tabs
• Round plug and round plug-in sleeves
• Pin cable lugs and ring cable lugs
• splices
• Forked cable lugs and tubular cable lugs
• ferrules

With these connecting elements and a crimping tool, a secure connection of flexible wires with plugs or rigid wires is established. Without such connections, connections for luster or plug-in terminals are not electrically safe and plug-in connections cannot be installed. This technique is used to repair electrical devices and to connect flexible wires with Western, BNC and RJ-45 plugs. For the latter, however, there are some special ones Western pliers crimping tools which compress the wire directly with the plug.

You will be used for a secure electrical connection. Therefore, the classic areas of application are the industry and the craft, the automobile industry and the building installation technology, the energy supply and the traffic.

How does a crimping tool work?

A crimping tool is mainly used to crimp wire-end ferrules onto fine-wire cables. To tame the many small wires in a strand and then jam them, ferrules are applied. The individual wires are assembled into a single contact. Crimping is a good and faster method than previous soldering of stranded wires.

Crimping tools usually have a toggle. Without this power amplifier, the force of the hand would not be sufficient to deform the connection so far that a permanently unsolvable connection results. Therefore, the crimping tool must always be suitable for the size of the ferrule, because each of the sizes produces different forces.

How to use a ferrule crimping tool?

How is a crimping tool optimally used? Here's a little one Crimping tool instructions

Prepare the cable

The cable must be cut at a right angle and stripped to about 10 centimeters. That can be with one Abisolierzange do well, so that the fine wires remain intact. Carefully twist the individual cable strands with your hand, so that no more wires stick out.

Prepare the crimping tool

Unsecure your crimping tool. On some models, this is also done by a firm compression. Select the wire end fitting suitable for the cable. It must not be too big or too small. In too small ferrules is not enough space and in too much threaten to later slide out the wires. For pressing there is a Crimping tool with side entry is available for storage, management and analysis.

Prepare the ferrule

Insert the stripped cable end into the ferrule. Make sure that no strands protrude. Insert the wire end ferrule into the appropriate size at the 90 ° angle on the labeled pliers side.

The crimping

Now close the clamp until it is firmly closed or until the last stop. Exactly apply the crimping tool and press it together with great force. Once this is done, the crimped ferrules can be removed. The stranded wires are optimally protected by the ferrule. The sleeve is firmly and permanently connected to the cable core

There is also a French color code, but we will not go into that here. Usually you will find a color key on the packaging, which is very helpful.

How to choose the right color code yourself

For example, remember a single color code for a cross-section of 1,00 mm². If your hardware store has bought in accordance with DIN, you need the wire end ferrules in yellow, he has stocked up to German standard, the red sleeves are needed for this cross section.

Which Western plug can be crimped?

Western connectors are all RJ connectors. RJ (Registered Jack) stands for a standardized socket. These jacks are used worldwide for telephone and network connections. Common are pairs with 4, 6 or 8 wires. The most important western plugs are:

Crimping Pliers Bestsellers on Amazon:

Our crimping pliers purchase advice

Before you get one Buy crimping pliers, you have to be aware of what you want to crimp or what sizes of ferrules are needed.

Which size is needed?

Pay special attention to which area you can machine wire crimpers with a wire end ferrule. The most common DIY diameters range from 0,5 to 2,5 mm², while 4, 6 or 10 and 16mm² are less frequently needed.

What pliers material is good?

The pliers material of the pressing surfaces is always made of solid steel or iron, since a fairly high force is needed for crimping. Professional crimping pliers You can also get extra durable chrome vanadium steel. It guarantees a long durability and is very resistant.

How should a good grip be?

They should be ergonomically shaped for easy use and easy to hold. A nonslip sheath have all the tongs out of our comparison, though Crimping pliers multi-component sheaths are particularly suitable for this.

Which profiles are available for crimping?

If wire end ferrules are pressed, they leave the clamp with a pressed-on profile. This is not a gimmick and no logo of the manufacturer. This is because the crimped material has to compress. In addition to square profiles, there are also trapezoidal profiles, rectangular, hexagonal or even spike or v-shaped profiles. Simple and cheap crimping tools usually press a trapezoidal or mandrel shape. Where the ferrule has little space in the clamp, hexagonal or square shapes are better.

What is a Forcible Lock?

Such a lock is available with crimping tools with automatic cross-section adjustment. It has the advantage that the pliers only open when the pressure has been exerted with a certain pressure. It is therefore called Zwangsspressung.

Where can you find the best crimping pliers?
