تفاوت بین کابل اتصال و اتصال دستگاه

تفاوت اتصال کابل و دستگاهاتصال دهنده

The cables themselves are useless unless they end with a اتصال دهنده or a more special coaxial اتصال دهنده. A coaxial اتصال دهنده allows one cable to be connected to another cable or a device. Therefore, there are two different types of اتصال دهندهs: those connected to the cable and those connected to the device. The device اتصال دهندهدارای فلنج چهار سوراخ

1. کابل متمرکز استاتصال دهنده

In a cable, the اتصال دهنده is mechanically tightly connected to the end of the cable. Once the اتصال دهندهبه کابل متصل می شود ، به مجموعه کابل تبدیل می شود. سپس مهندسان RF هر قسمت را با توجه به نیازهای خود متصل می کنند. هنگامی که فقط به چند مجموعه کابل نیاز است ، مقرون به صرفه تر و سریعتر مونتاژ می شود. اما وقتی تعداد زیادی کابل کابل مورد نیاز است ، بهتر است مجموعه کابل خریداری کنید.

2. اتصال دهنده

هدف هر کداماتصال دهنده is the same, with minimum insertion loss. Although the insertion loss of the اتصال دهنده is very small compared with the cable, the اتصال دهنده does have an insertion loss, and there are many different types of اتصال دهندهs. Almost all اتصال دهنده families have اتصال دهندهs suitable for cables and devices. As a general rule, the اتصال دهندهs of one group will not match the اتصال دهندهs of another group.
Because some اتصال دهندهs 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 اتصال دهندهs to the small اتصال دهنده family available. If the cable needs to carry high-power radio frequency signals, a large-diameter cable is required, so a large کانکتوr مورد نیاز است

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

3. آداپتور

به دلیل این متفاوت بودناتصال دهندهخانواده ها ، پدیده جالبی پدید آمده است. مهندسان RF مجبور می شوند کابل را با یک کابل وصل کننداتصال دهنده to another cable or device with a different اتصال دهنده family. This cannot be done. The adapter is that they are in step. Adapters, also called coaxial adapters, are short bilateral اتصال دهندهs. On one side is one type of اتصال دهنده, and once is another type of اتصال دهنده.
