Rozdiel medzi káblovým konektorom a konektorom zariadenia

Rozdiel medzi káblovým konektorom a zariadenímkonektor

The cables themselves are useless unless they end with a konektor or a more special coaxial konektor. A coaxial konektor allows one cable to be connected to another cable or a device. Therefore, there are two different types of konektors: those connected to the cable and those connected to the device. The device konektormá štvorotvorovú prírubu.

1. Kábel centralizovanýkonektor

In a cable, the konektor is mechanically tightly connected to the end of the cable. Once the konektorje pripojený ku káblu, stáva sa z neho káblová zostava. RF inžinieri potom spoja každú časť podľa vlastných potrieb. Keď je potrebných iba niekoľko káblových zväzkov, sú cenovo dostupnejšie a rýchlejšie sa montujú samy; ale keď je potrebných veľa káblových zostáv, je lepšie kúpiť káblové zostavy.

2. Konektor

Cieľom každéhokonektor is the same, with minimum insertion loss. Although the insertion loss of the konektor is very small compared with the cable, the konektor does have an insertion loss, and there are many different types of konektors. Almost all konektor families have konektors suitable for cables and devices. As a general rule, the konektors of one group will not match the konektors of another group.
Because some konektors 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 konektors to the small konektor family available. If the cable needs to carry high-power radio frequency signals, a large-diameter cable is required, so a large connector sa vyžaduje.

The second reason is evolution. As the times change, konektor 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 konektor type each time.

3. Adaptér

Kvôli týmto rôznymkonektorrodín, objavil sa zaujímavý jav. RF inžinieri sú nútení pripojiť kábel s jednýmkonektor to another cable or device with a different konektor family. This cannot be done. The adapter is that they are in step. Adapters, also called coaxial adapters, are short bilateral konektors. On one side is one type of konektor, and once is another type of konektor.
