Crimping pliers for professional and safe electrical connections

Definition and functionality: What are crimping pliers?

Crimping pliers are special tools that connect various electrical contacts such as cable lugs, wire end sleeves or contacts. Mechanical pressure is used to create a conductive and firm connection between the contact or plug and cable - no soldering is required.

The advantages of crimp connections are obvious: They are stable and reliable, have low contact resistance and are professionally processed. In addition, crimping tools are required for different contact types and cable cross-sections. Our tip: In the professional sector, always have the appropriate tool set on hand for each type of contact.

How a crimping tool works is simple. With the help of integrated jaws, the pliers shape the material of the contact so that it wraps around the cable permanently and securely and rests there. When it comes to reliable and secure electrical connections, wire end ferrule pliers are essential in various areas of application.

What types of crimping pliers are there?

The pliers are available in different versions. They differ, among other things, according to the area of ​​application, requirements and the material. Each crimping tool is suitable for certain types of contacts and cable cross sections. We have summarized the most common types for you:

•       Manual crimping pliers: They are compact, easy to use and good for small DIY projects or occasional jobs. Such crimping pliers (e.g. four-pronged crimping pliers) are used entirely by hand power using a lever mechanism.

•       Electric hand crimping pliers: Such models usually have an electric drive through which the crimping force is transferred to the connection; As a user you just have to start the process. This is why these crimping pliers are particularly suitable for larger work volumes. A power source is required.

•      Semi-automatic: This variant offers a mechanical crimping process; the user simply inserts the cable and crimping sleeve manually. This enables greater speed in the workshop, but of course involves occasional maintenance work and higher costs.

•      Fully automatic machines: Such machines completely take over the process from cable length measurement to positioning and crimping. This means they offer high speed and can be used in series production in the industrial sector. However, the acquisition costs are very high and qualified personnel are required for operation.

Common applications – precise connections for every industry

Crimping tools are indispensable in many industries. They are used wherever safety and precision are required in electrical connections:

• Industry and production – In order to process large quantities of contacts precisely and safely, crimping pliers are essential in industrial manufacturing and production.
• Domestic and electrical engineering – Application for various cabling in household appliances, network installations or in control cabinets.
• Automotive electrical systems – Whether professional wiring or repairs: With these pliers you can create connections of cables with various contacts such as cable lugs, plugs or wire end sleeves in vehicle construction.
• Model making and DIY – The pliers for simple contact connections are also used for smaller repairs, projects or model making.
• Aerospace – High-precision and lightweight connections are required here. With professional cable crimping pliers, contacts can be achieved that meet the highest demands.
• Renewable energies – Secure and weather-resistant connections between cables and contacts in wind turbines or solar systems.

Crimping pliers for vehicle plugs and other electrical connections - that's why the right crimping tool is important

In order to ensure the functionality and reliability of complex systems, electrical connections play a crucial role in the automotive sector. No matter whether MQS, AMP or JPT contacts: A precise connection is required for each type to ensure maximum stability and conductivity.

This is why having the right tools is essential to create secure and long-lasting connections. If you choose inaccurate or even incorrect pliers, this can lead to increased resistance, short circuits or loose connections.

Therefore, choose exactly the right pliers to ensure correct pressing. This is essential, especially in the safety-critical automotive sector. Don't know which pliers are needed for your area? Contact us, we will be happy to help you.

Buy crimping pliers – this is what you should pay attention to

To create reliable and secure electrical connections, choosing the right crimping tools is essential. Pay attention to the following criteria:

•       Compatibility: Is the pliers suitable for your area of ​​application and the desired plug and contact types?

•       Adjustment options: Variable adjustable pliers enable easy adjustment to different types of contacts and cable cross sections.

•       Ergonomics: Easy-to-use mechanisms and non-slip handles enable safe and comfortable work. This is especially true for professional and long work.

•       Connection type/contact: Make sure that the respective pliers are suitable for the desired contact types (e.g. MQS or JPT).

•       Profile shape: Depending on the area of ​​application and type of contact, different crimp profile shapes (e.g. rectangular, square or round) are integrated.

•       Introduction: With a specific cable entry you can work more easily and precisely. Side entry and front entry are available here.

•       Cable cross section and cable diameter: The cable cross section refers to the cable area (e.g. 10 mm² or 16 mm²), while the cable diameter refers to the outer size of the cable to be crimped.

•       Spare parts and accessories: With interchangeable spare parts and accessories, your crimping tools remain precise and you can expand the range of functions if necessary. You will find interchangeable jaws for crimping pliers, among other things.

In our shop we have already assigned the crimping pliers to the appropriate contacts so that you can quickly find the corresponding products.

Crimping pliers for different types of contacts – precision for every connection

Choosing the right pliers is crucial because there are different contacts and connectors that have different requirements. Only with the right crimping pliers can you create conductive, secure and long-lasting connections. However, if you choose the wrong pliers, this can lead to inaccurate crimping and associated failures or contact problems.

The pliers are available for the following contact and connection types, among others:

• JPT
• MQS
• Tyco
• AMP
• Deutsch DT
• Deutsch DTM
• Deutsch DTP
• Kostal
• Bosch
• Delphi
• VW Connectors

Explained step by step: How to use crimping pliers correctly

It's not just the right tools that are required to create stable and secure connections. The right approach and technology are also crucial to making the work simple and efficient.

Here are the basic steps for successful crimping:

1.    Select the appropriate pliers for the appropriate contact and correct use. Also check whether the cable diameter and cross section are correct.

2.    Use the wire strippers to remove the insulation from the cable to the required length. Be careful not to damage the wire.

3.    Insert the desired contact into the pliers. Pay attention to the correct alignment.

4.    Now insert the stripped cable into the contact until it is deep enough and secure.

5.    Now squeeze the pliers together until the connection point of the contact or plug is securely pressed. With ratchet pliers, the ratchet only releases when the crimping process is completely completed.

6.    Check that the connection of the contact or plug is secure. Also make sure it fits evenly and securely.

What is the difference between crimping pliers and pressing pliers?

A look at the two types of pliers shows that they differ primarily in their area of ​​application and function. They are primarily used to create electrical connections for contacts, plugs or wire end sleeves.

Pressing tongs, on the other hand, are used to press other materials. These include, among other things, metal parts and pipes. They are much more universally applicable. However, both tools have one thing in common: they work with pressure, but in different areas of application.
