Why does the connector fail

图片
The inner conductor of the connector is smaller in size relative to the outer conductor, and the inner conductor having a lower strength is more likely to cause poor contact and cause the connector to fail. ​ ​ 1.The inner conductor is not fixed firmly For assembly purposes, in many RF coaxial connectors, the inner conductor is divided into two sections at the media support and then threaded. However, due to the small diameter of the inner conductor, if the glue is not fixed at the screw connection during assembly, the strength of the inner conductor connection is very poor, especially for some small RF coaxial connectors.  Therefore, when the connector is connected and disconnected multiple times, under the long-term action of the torque and the pulling force, the inner conductor thread may loosen and fall off, resulting in the connection failure.
