Cable assembly is an electrical connection assembly used to connect different electronic equipment systems or subsystems. It is composed of various insulated wires, shielded wires and electrical connectors. With the wide application of cable components in the field of communication, the requirements of electrical stability, service life and environmental resistance of cable components are becoming higher and higher. At present, the commonly used cable components are connectors at both ends, intermediate cables, cables and connectors are connected by crimping, mounting or welding, and covered with heat shrink sleeve or injection molding protection. Now let’s look at how it can be installed.
There are three main ways to assemble cable components:
First, direct welding type: cable inner conductor and connector inner conductor; Solder the outer conductor of the semi-rigid cable to the outer conductor of the connector. Special assembly tools are required.
Advantages: 1. The connection line can be good. 2. The welding structure has high stiffness and good integrity. 3. There are many kinds of welding methods and wide applicability of welding process, which is relatively easy to be realistic.
Two, crimping type: cable shield layer is crimped sleeve with special crimping clamp crimping fixed on the connector, simple structure, fast installation speed, good consistency, high reliability, the structure is suitable for flexible cable.
Advantages: 1. Simple structure. 2. Fast installation speed. 3. Good consistency; 4. High reliability.
Three, clamping type: when assembling connectors and cables, the nut structure is used to connect and fix the cable shielding layer with the outer conductor of the connector shell through the clamping mechanism. The structure is suitable for flexible cables and feeder cables.
Advantages: 1. Press copper terminal is very convenient, in line with the actual requirements can be easily realized chain bridge. 2. When the wire terminals are closely adjacent, it can improve insulation safety and prevent wire bifurcation. 3. The wire can be easily inserted into the end.
Cable assembly is a kind of high precision use of consumables, incorrect operation, high strength and frequent use will shorten the service life of the cable, so we should pay attention to the routine maintenance of cable assembly in peacetime use. There is also the application of different connector installation will be different, we must distinguish well.
