The SMA connector is a component installed in cables or instruments for the electrical connection or separation of transmission lines, which is an important part of technically demanding electrical connectors. The correct installation of the SMA connector can extend the life of products and reduce maintenance costs. Therefore, it is necessary to understand some SMA connector installation methods and precautions. Next will explain how to properly install SMA connectors through our product SMA connector RG174 from LenoRF.
1、Before installing SMA connector RG174 and its assemblies, performance, and safety tests need to be performed and design work needs to be done according to the environment. When selecting SMA connector RG174 and assemblies, installation factors should be considered， such as electrical performance, mechanical performance, and so on. Portable RF tools with SMA connectors and assemblies, hardware, and components must ensure good RF operation and electrical isolation.
2、Some equipment may be dusty and dirty before installing SMA connector RG174 and its assemblies. Therefore, it is important to note that particles in the SMA connector and its components can degrade the performance of the coaxial connector and even cause sparks and failures at high power levels. Due to the energy characteristics of the SMA connector, even without the coaxial port of the assembly, it needs to be properly ported to avoid interaction, entry, or interference with the outside world.
3、In contrast to standard terminals, the SMA connector and its assemblies are specially designed. In addition, SMA connector RG174 and its assemblies can be supplied with one or more shorting terminals depending on the electrical requirements of the particular port, to prevent loss or damage to the cover when frequent access to the port is required.
4、Before installing the SMA connector RG174 and its assemblies, consideration should be given to the proper fit between the socket and the pins. This can be measured by the insertion and retention forces when standard pins are mated to the conductors in the socket. By adjusting the size and tolerance of the jack and pins, as well as the aging process of the wires in the 4-hole-flange SMA connector jack, the insertion and retention forces between the pins and the jack can be within the proper range.
Steps for proper installation of SMA connectors
1、The first step is to solder the inner core of the cable to the inner pin.
2、The second step is to thread the cold compression and heat shrink tubing onto the cable.
3、The third step is to solder the cable with the inner pin and then pass it through the smaller end of the SMA connector interface.
4、The fourth step is to hug the solder hole with the cable shield.
5、The fifth step is to push the cold compression tube from the cable end to the connector end and press it into the shield.
6、The last step is to use crimping pliers to compress the cold compression tubing.
