VNA Test Cable is an electrical connection component 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 VNA Test Cable in the communication field, the requirements for the stability of the electrical performance, service life and environmental resistance of the VNA Test Cable are also getting higher and higher. At present, the commonly used VNA Test Cables are both ends of the connector, the intermediate cable, the cable and the connector are connected by crimping, assembling or welding, and the jacket is heat-shrinkable sleeve or injection molding protection. Next, let's take a look at how it is assembled.

VNA Test Cable
There are three main ways to connect the VNA Test Cable:
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 welded 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, use the nut structure 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. Makes the wire easier to insert into the terminal.

VNA Test Cable 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 routine maintenance of VNA Test Cable in normal use. In addition, the installation methods of different connectors in different applications will also be different, and everyone must distinguish them well. The above is the whole content of the small series to explain what VNA Test Cable is, the application and installation of VNA Test Cable.
