Wire cables are most often used in home installations. Stranded cables are less common. One cable consists of several (in some cases even several dozen) wires, and the whole is characterized by high flexibility and elasticity, as well as the possibility of connection without the use of external connectors. This makes them perfect for switchboards as connection elements for switches located on a DIN rail.
Ferrule terminals are used to connect stranded wires. Elements of this type consist of two basic parts. The first is a conductive fragment in the form of a ferrule crimped at the end of the cable. The second one is plastic insulation adapted to the size of the cable. Sleeve terminals are available in various sizes, which allows them to be adapted to the specificity of a given installation.
When is a ferrule crimper used?
Special crimping tools are used to crimp the sleeves. Unlike regular pliers, they ensure high precision in crimping. This increases the contact area between the wires and the terminal, which translates into the efficiency and safety of wires in electrical circuits. They enable professional and safe connections of cable ends, both single- and multi-core. Compared to screwing or soldering, making connections using crimping tools is much faster and more precise.
Ferrule crimpers are used not only when installing electrical installations in residential, commercial or industrial buildings. Since stranded cables are often used in electrical and electronic devices (e.g. TVs), they are important equipment in production plants and services dealing with this type of equipment. They are also used in the automotive industry. When connecting wires in electrical systems, such as lighting, control systems or power supply systems, crimping tools enable reliable and durable connections, which is important for the reliability and safety of the vehicle.
How to crimp ferrules?
The quality of operation of a given installation depends on the precision of crimping the ferrules. To avoid related problems, you should learn the rules of proper crimping and how to choose the right ferrule crimper. Regarding this first aspect, it is important to select the appropriate clamping force. Avoid twisting the wires too tightly to maintain the flexibility of the cable.
After installing the ferrule, the cable and ferrule are inserted into the appropriate opening of the crimper, which is adapted to the size of the ferrule. Then, holding the tool in your hand, the handle of the crimper should be tightened vigorously, which will tighten the ferrule on the cable. The procedure is similar also in the case of crimping the ferrule on several wires at the same time. However, it is worth remembering to twist the wires in parallel before applying the sleeve. This method ensures a durable and even connection.
How to choose the right ferrule crimper?
When choosing a crimper, the most important thing is to determine the cross-sectional range of the wires you will work with. Depending on the type of application, it is worth paying attention to whether a given crimper can work with both smaller and larger cables. There are both universal models available on the market, supporting a wide range of cross-sections, and those dedicated to specific sizes of ferrules and wires. Another issue is the type of clamps. When choosing a crimper, it is worth making sure that it is compatible with the various types of ferrules you will use in your projects.
Ergonomics and comfort of use are also key issues. The crimper should fit well in your hand, allowing precise and secure crimping. It is also important that the tool is easy to use, which makes work faster and easier. Some models of crimping machines have additional functions, such as locking the opening after crimping or automatic adjustment to the sleeve size.
Ferrule crimpers are among the most important tools for electrical installers. They are also widely used in industrial and automotive plants. Their precise operation, enabling secure and durable connection of wires, contributes to the safety and reliability of electrical circuits. When choosing a crimper, it is worth carefully analyzing your needs and then comparing them with the parameters of a given model.
