Cable assemblies are electrical connection kits which used to join different electronic systems or subsystems, and are consist of insulated wires, shielded wires, and connectors. With the widespread application of cable assemblies, the requirements for its stability, service life and environmental friendly are increasing. Cable assemblies use crimping, mounting or soldering methods to be connected, and protected by heat shrink tubes or injection molding.

There’re 3 ways for cable assemblies connection：

1. Clamping type: when assembly, use clamp tool to fix the shield layer with connector shell conductor, the type is suitable for flexible cables and feeder cables. Its advantages as follows: 1. It’s very convenient to crimped terminals, and easily achieve chain bridging.  2. When the conductor wiring is placed close to each other, it can improve the insulation safety and prevent the wire from splitting. 3. make the wires easier to insert the terminals.

2, crimp type: cable shield is crimped with a crimping tool fixed on the connector, the type is suitable for flexible cables. Following advantages: 1. simple structure; 2. fast assembly; 3. good consistency; 4. high reliability.

3, Soldering type: connect the cable inner conductor and connector inner conductor; Tin soldered the semi-rigid cable outer conductor and connector outer conductor, need to use special assembly tools. Its advantages: 1. good connection performance; 2. solder structure with high rigidity; 3. various types of soldering methods, wide applicability of the soldering process, and easier to achieve.

The cable is high-density materials, high frequency of use and incorrect operation will reduce the lifetime, so we need to pay attention to the maintanance, and remember that the application of different connectors, and the connection methods will be also different.
