[0002] Connectors are indispensable components in electronic devices. They build a bridge of communication between blocked or isolated circuits within the circuit, so that current can flow and the circuit can achieve its intended function. The components that are connected to coaxial cables, microstrip lines or other RF transmission lines to achieve electrical connection, separation or transfer of different types of transmission lines are called RF connectors. RF connectors are divided into flange-mounted and through-the-wall-mounted types according to the shell form.
