What are the main components of wire and cable?

With the development of electronic technology, the application of cable accessories in the electronic communication industry is also more and more extensive, affecting all aspects of our work and life. Today, Xiaobian network will learn what cable components are, and the application and installation of cable components.

First, what is the cable assembly

The cable assembly is an electrical connection component used to connect different electronic equipment systems or sub-systems, and is composed of various insulated wires, shielded wires and electrical connectors. With the wide application of cable assembly in the field of communication, the requirements of electrical stability, service life and environmental resistance of cable assembly are becoming higher and higher. At present, the commonly used cable assemblies are two-end connectors, intermediate cables, cables and connectors are connected by crimping, mounting or welding, and are covered with heat shrink bushing or injection molding protection.

Second, the application of cable components

1, cable assembly characteristics:

High-speed cable assembly;

Standard and custom cable options available;

Suitable for all standard interfaces including: SMA 2.92mm / 2.4mm and SMP/SMPM/SMPS;

Low tinning and high flexibility, allowing several height bends after the cable buckle;

High flexibility to maintain excellent performance after repeated use;

DC: 50 GHz.

2, the application of cable components

Short cable routing saves space and weight

Ideal for applications requiring high flexibility and low loss

Used as a laboratory test cable for low-loss, demanding applications up to 50 GHz

Third, the installation of cable assembly

There are three main ways to install cable assemblies:

1, 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. Welded structure stiffness, good integrity; 3. There are many kinds of welding methods, and the welding process is widely applicable, which is relatively easy to be realistic.

2, crimping type: the 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 cables.

Advantages: 1. Simple structure; 2. Fast installation speed; 3. Good consistency; 4. High reliability.

3, 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. The copper terminal is very convenient, in line with the actual requirements can be easily realized chain bridge; 2. When the wire connection is closely adjacent, it can improve the insulation safety and prevent the wire from bifurcating; 3. Can make the wire easier to insert the end.

Cable assembly is a high-precision use of consumables, incorrect operation, high-strength frequent use will shorten the service life of the cable, so we should pay attention to the routine maintenance of cable assembly when we are usually in use. There is also the application of different connector installation methods will be different
