Razlika med kabelskim priključkom in napravopriključek

The cables themselves are useless unless they end with a priključek or a more special coaxial priključek. A coaxial priključek allows one cable to be connected to another cable or a device. Therefore, there are two different types of priključeks: those connected to the cable and those connected to the device. The device priključekima prirobnico s štirimi luknjami.

1. Kabel centraliziranpriključek

In a cable, the priključek is mechanically tightly connected to the end of the cable. Once the priključekpriključen na kabel, postane kabelski sklop. Inženirji RF nato povežejo vsak del glede na lastne potrebe. Ko je potrebnih le nekaj kabelskih sklopov, so cenovno ugodnejši in jih je hitreje sestaviti sami; če pa je potrebno veliko kabelskih sklopov, je bolje kupiti kabelske sklope.

2. Priključek

Cilj vsakegapriključek is the same, with minimum insertion loss. Although the insertion loss of the priključek is very small compared with the cable, the priključek does have an insertion loss, and there are many different types of priključeks. Almost all priključek families have priključeks suitable for cables and devices. As a general rule, the priključeks of one group will not match the priključeks of another group.
Because some priključeks are large in physical size, while others are small. If an inexpensive cable assembly is needed, then choose a small diameter cable, which limits the choice of priključeks to the small priključek family available. If the cable needs to carry high-power radio frequency signals, a large-diameter cable is required, so a large connector je obvezen.

The second reason is evolution. As the times change, priključek manufacturers often improve the connection according to actual needs, or reduce the insertion loss, or facilitate the use of the connection. Significant changes are made to an existing priključek type each time.

3. Adapter

Zaradi teh različnihpriključekdružine, se je pojavil zanimiv pojav. Inženirji RF so prisiljeni povezati kabel z enimpriključek to another cable or device with a different priključek family. This cannot be done. The adapter is that they are in step. Adapters, also called coaxial adapters, are short bilateral priključeks. On one side is one type of priključek, and once is another type of priključek.
