When the pressing portion is pressed down, the projection on the front end portion can be driven to move downward. When the plug connector is inserted into the receptacle connector, the pressing portion needs to be pressed down to drive the projection to move downward so that the projection can pass over the front end face of the top wall and eventually reach the groove or recess of the top wall. At this time, the pressing portion is released, and the protrusion projects upward into the groove or recess of the top wall by the elastic restoring force of the pressing portion, thereby realizing the locking of the plug connector and the socket connector. However, when inserting the plug connector into the socket connector, first press the 4 δ pressing portion to drive the protrusion downward to insert the plug connector into the socket connector. The protrusion lacks the guiding structure. When the pressing portion is pressed down, the projection of the plug connector is blocked by the front end face of the top wall and the plug connector cannot be inserted into the socket connector. The projections in the prior art lack a guiding structure, making the plug connector less convenient when inserted into a receptacle connector. In view of the above problems, it is necessary to design a new plug to solve the above technical problems.
