The beneficial effect of above-mentioned structure is: this female shell of gluing adopts joint complex mode to be connected with public gluey shell, the assembly of the female shell of gluing of being convenient for and public gluey shell is favorable to improving assembly efficiency, and the female jam plate that is provided with the locking effect on gluing the shell, this connector is when receiving the vibration, public gluey shell is difficult to the pine with the female shell of gluing to take off, it is compacter to connect, and public gluey shell is last to be provided with prevents reverse installation reference column, can effectively avoid this connector to turn over, thereby this connector has simple structure, the stable performance is reliable, it is convenient to assemble, connect reliable advantage.

Particularly, two sides of one end of the female terminal are respectively bent in opposite directions and are provided with a square-frame-shaped plugging portion, the other end of the female terminal is provided with a wire pressing portion in pressure connection with an external wire, a contact elastic sheet is arranged in the plugging portion, and a plugging space for a male terminal to be plugged is formed between the contact elastic sheet and the inner wall of the plugging portion. The plug-in part is designed into a full-wrapping square frame shape, so that the connection between the male terminal and the female terminal is more compact, and the connection reliability of the connector is favorably improved.

Particularly, the outer wall of the insertion part is provided with a bending limiting piece, a limiting groove is formed in the mother rubber shell corresponding to the bending limiting piece, and the bending limiting piece is clamped in the limiting groove and forms limiting fit of the mother terminal and the mother rubber shell. Female terminal and female gluey shell adopt spacing complex mode to be connected, have guaranteed that female terminal and female gluey shell are connected compacter, and female terminal is difficult for the pine to take off, is favorable to the connection reliability of this connector.
