Plug structure and automatic detection system

The utility model provides a plugging structure and an automatic detection system. The plugging structure comprises a slide rail assembly, a plugging module, a cylinder module and a first fixing plate. The sliding rail assembly comprises a fixed rail and a movable rail capable of sliding relative to the fixed rail, and the fixed rail is fixedly arranged on the first fixing plate. The plugging module is connected to the movable rail. The air cylinder module comprises an air cylinder, a push rod and an elastic element, the push rod is connected between the air cylinder and the plugging module, and the push rod is sleeved with the elastic element. The push rod is used for pushing the plugging module to move in the sliding direction of the movable rail under the driving force of the air cylinder, so that the plugging module drives the plugging head to be plugged in the port module. According to the plugging structure and the automatic detection system, flexible plugging of the communication cable can be realized,
