Protection device for fault detection of 5G wireless communication equipment

The invention relates to the technical field of communication, and especially relates to a protection device for fault detection of 5G wireless communication equipment. Fixation of a protection mechanism on detected communication equipment is realized through attraction between a magnetic strip mounted on the bottom surface of a chassis and the outer wall of the detected communication equipment during use. When a user uses the device, the user holds the pen cap end of an insulating end to extend the bottom of the conductive end into a detection port for detection, a current display screen faces a worker directly, the worker can observe the current condition of the detected port without moving the position, the conductive end is isolated through a protection mechanism, an electric shock accident caused by mistaken touch of the conductive end by the worker is prevented, and the operation safety is improved. If the current of the detected port is short-circuited, the instantaneously increased current fuses the t
