ຄວາມແຕກຕ່າງລະຫວ່າງຕົວເຊື່ອມຕໍ່ສາຍໄຟແລະຕົວເຊື່ອມຕໍ່ອຸປະກອນ

ຄວາມແຕກຕ່າງລະຫວ່າງຕົວເຊື່ອມຕໍ່ສາຍໄຟແລະອຸປະກອນຕົວເຊື່ອມຕໍ່

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

1. ສາຍກາງຕົວເຊື່ອມຕໍ່

In a cable, the ຕົວເຊື່ອມຕໍ່ is mechanically tightly connected to the end of the cable. Once the ຕົວເຊື່ອມຕໍ່ໄດ້ເຊື່ອມຕໍ່ກັບສາຍໄຟ, ມັນຈະກາຍເປັນບ່ອນປະກອບສາຍໄຟ. ຫຼັງຈາກນັ້ນວິສະວະກອນ RF ເຊື່ອມຕໍ່ແຕ່ລະພາກສ່ວນຕາມຄວາມຕ້ອງການຂອງຕົນເອງ. ເມື່ອຕ້ອງການການປະກອບສາຍໄຟພຽງແຕ່ສອງສາມອັນ, ພວກມັນມີລາຄາຖືກກວ່າແລະໄວກວ່າໃນການປະກອບດ້ວຍຕົວມັນເອງ; ແຕ່ເມື່ອຕ້ອງການການປະກອບສາຍໄຟຫຼາຍ, ມັນດີກວ່າທີ່ຈະຊື້ການປະກອບສາຍໄຟ.

2. ຕົວເຊື່ອມຕໍ່

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

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

3. ອະແດັບເຕີ

ເນື່ອງຈາກວ່າເຫຼົ່ານີ້ແຕກຕ່າງກັນຕົວເຊື່ອມຕໍ່ຄອບຄົວ, ປະກົດການທີ່ ໜ້າ ສົນໃຈໄດ້ເກີດຂື້ນ. ວິສະວະກອນ RF ຖືກບັງຄັບໃຫ້ເຊື່ອມຕໍ່ສາຍໄຟໃສ່ກັບສາຍ ໜຶ່ງຕົວເຊື່ອມຕໍ່ to another cable or device with a different ຕົວເຊື່ອມຕໍ່ family. This cannot be done. The adapter is that they are in step. Adapters, also called coaxial adapters, are short bilateral ຕົວເຊື່ອມຕໍ່s. On one side is one type of ຕົວເຊື່ອມຕໍ່, and once is another type of ຕົວເຊື່ອມຕໍ່.
