1. What is a cable assembly

Cable assemblies are electrical connection assemblies used to connect different electronic equipment systems or sub-systems, and are composed of various insulated wires, shielded wires and electrical connectors. With the wide application of cable assemblies in the field of communication, the requirements for the stability of electrical performance, service life and environmental resistance of cable assemblies are also getting higher and higher. At present, the commonly used cable assemblies are both ends of the connector, the intermediate cable, the cable and the connector are connected by crimping, assembling or welding, and are covered with heat-shrinkable sleeves or injection-molded protection.

Second, the application of cable assemblies

1. Characteristics of cable assemblies:

High-speed cable assemblies;

Standardized and custom cable options available;

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

Low tin climbing and high flexibility, allowing several high bends after cable ties;

High flexibility to maintain excellent performance after repeated use;

DC: 50 GHz.

2. Application of cable assemblies

Short cable runs save space and weight

For applications requiring high flexibility and low losses

Can be used as lab test cable for low loss harsh applications up to 50 GHz

3. Installation of cable assemblies

There are three main ways to install cable assemblies:

1. Direct welding type: the inner conductor of the cable and the inner conductor of the connector; the outer conductor of the semi-rigid cable and the outer conductor of the connector are soldered and connected, and special assembly tools are required.

Advantages: 1. The connection line can be good; 2. The welding structure has high rigidity and good integrity; 3. There are many types of welding methods, and the welding process has wide applicability and is relatively easy to be realistic.

2. Crimping type: The cable shielding layer is crimped and fixed on the connector by a special crimping pliers. The structure is simple, the assembly speed is fast, the consistency is good, and the reliability is high. This structure is suitable for flexible cables.

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

3. Clamping type: When assembling the connector and the cable, 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. This structure is suitable for flexible cables and feeder cables.

Advantages: 1. It is very convenient to press copper terminals, and it can easily realize chain bridging in line with actual requirements; 2. When the wiring positions of the wires are closely adjacent, it can improve the insulation safety and prevent the wires from bifurcating; 3. It can make The wire is easier to insert into the terminal.

The cable assembly is a kind of high-precision consumables. Improper operation, high-intensity and frequent use will shorten the service life of the cable, so everyone should pay attention to the regular maintenance of the cable assembly in normal use. In addition, the installation methods of different connectors in different applications will also be different, and everyone must distinguish them well.
