The operation part 123 is exposed to the outside, which is convenient for the operator to operate. The removal auxiliary slot 2111 provides a moving space for the first-stage stopper 150, so as to facilitate the removal operation, and the auxiliary removing member 360 facilitates the female connector 100 to be quickly pushed out from the male connector 200, thereby improving the removal efficiency.

Preferably, a sliding groove is formed in the male plug-in unit 200, and a sliding strip is arranged on the female body plug-in unit 110, and the sliding strip is slidably inserted into the sliding groove. More preferably, the sliding groove is opened on the end surface of the male plug 200 facing away from the guiding and locking groove 210, and the sliding strip is arranged on the end surface of the female body plug 110 facing away from the female plug spring 120.

The construction, features and functions of the present invention have been described in detail for the purpose of illustration and description, but the invention is not limited to the details of construction and operation, and is capable of other embodiments without departing from the spirit and scope of the invention.
