To connect a stripped conductor of a cable to another cable or a suitable connector or adapter without having to solder, it is possible to use crimping pliers. The crimping pliers can directly connect cables by pressure, or with the help of a ferrule, crimp connectors, or other tools, establish a clean electrical connection. Crimping pliers have different depths of impressions and uses for different cable types and cable cross-sections, making them flexibly adaptable for their specific purposes.
What does crimping mean?
The word crimping (crushing) is used in various fields to express that something is being squeezed together to create a so-called press connection.
What does crimping mean in the electronic field?
Crimping with crimping pliers means pressing two cable connections together with pressure. The crimping pliers apply such a high pressure by the force of the hand that the cable ends are squeezed together through their pressure points to create a stable electrical connection.
Which crimping pliers are the right ones for my connector?
- Crimping pliers for round connectors are suitable for cable ends with twisted contacts.
- 4-notch crimping pliers are suitable for D/E/C/Yellock crimp contacts.
- Crimping pliers for RJ45 connectors or crimping pliers for Western connectors of different widths are suitable for modular/network connectors and are usually equipped for the common types RJ 45, 11.68 mm.
- Crimping pliers for F-connectors are suitable for cable types such as RG 6, RG 58, RG 59, RG174. It is important to pay attention to the millimeter specifications of the crimping pliers manufacturer.
- Crimping pliers for crimp connectors and cable lugs usually offer 3 variations of the pliers for the most common connections of: 0.5 mm² - 1 mm² (red), 1.5 mm² - 2.5 mm² (blue), and 4 mm² - 6 mm² (yellow) and are marked accordingly.
- Crimping pliers are also available in sets, which provide the matching connectors for the pliers in different strengths for the cable cross-sections.
Crimping pliers for crimp connectors / cable lugs:
Crimp connectors have different colors that are meant to indicate the cable cross-section in millimeters. A crimping pliers has the colors with the corresponding mm value for the cable cross-section depicted on the pliers, so that a stable connection for the standardized cables can be created by creating a plastic deformation to a mechanically strong and electrically secure connection through pressure.
Crimping pliers for ferrules:
The ferrules must be suitable for the cable cross-section. Therefore, in the first step, it should be checked whether the ferrules are suitable for your cable. The cable should now be stripped to fit the ferrule, so that the plastic strands can completely fill the sleeve. Once your cable is fitting correctly in the ferrule, a stable mechanical connection can be made with the crimping pliers through the pressed pressure.
Crimping pliers for wire-end ferrules:
The wire-end ferrules must be suitable for the cable cross-section. Therefore, in the first step, it should be checked whether the wire-end ferrules are suitable for your cable. The cable should now be stripped appropriately for the wire-end ferrule so that the plastic wires can completely fill the ferrule. If your cable fits properly into the wire-end ferrule, a stable mechanical connection can be established by using the crimping pliers to apply pressure.
Crimping pliers for modular connectors / network connectors (RJ45 connectors)
- To establish a connection between a modular connector / network connector, a special crimping pliers is needed.
- Firstly, a strain relief sleeve should be slipped over the cable. Then, the cable ends are exposed and sorted according to colors for the corresponding intended use.
- The cable ends are then inserted into the connector without being previously stripped, taking care to ensure that the cables are in the correct order in the individual wire slots of the connector.
- The cutting contacts of the connector, into which the cable wires have been inserted, such as the RJ45 network connector, are then pressed together using the crimping pliers to establish an electrical connection.
- In addition, the cable shielding is contacted with the connector through crimping. Finally, the strain relief sleeve, which is located at the rear of the cable, is pushed over the connector, resulting in a completed LAN cable or patch cable.
