Particularly, the male rubber shell is provided with a clamping block, the female rubber shell is provided with a clamping hook matched with the clamping block, one side of the clamping block is provided with a guide inclined plane, the other side of the clamping block is provided with a limiting inclined plane, and the clamping hook can slide to the limiting inclined plane along the guide inclined plane and form clamping matching of the clamping hook and the clamping block. The clamping block is provided with a guide inclined plane and a limiting inclined plane respectively, when the clamping block is inserted, the clamping hook can slide along the guide inclined plane, the effect of reducing the insertion force can be achieved, the limiting inclined plane can limit the clamping hook to be loosened, the effect of increasing the extraction force can be achieved, and therefore the connector has the characteristics of small insertion force and large extraction force.

Particularly, the both sides of public terminal on be provided with spacing piece respectively, public gluey shell in be provided with spacing piece matched with spacing groove, spacing piece block in spacing inslot and constitute the joint cooperation of public terminal and public gluey shell. The limiting piece on the male terminal can play a role in preventing loosening, and the male terminal can be prevented from loosening and falling off due to external tension.

In particular, two sides of the male rubber shell are respectively provided with a buckle. Be provided with the buckle on public gluey shell to the installation of this connector of being convenient for, it is more convenient to install.
