The beneficial effect of above-mentioned structure is: be provided with respectively on the both sides of female rubber shell with public gluey shell matched with direction lug, guide block, direction lug, guide block can play and prevent inserting the effect of turning over, can avoid public gluey shell and female rubber shell to insert, can guarantee that public gluey shell and female rubber shell can reliably be connected. Therefore, the connector has the advantages of simple structure, stable and reliable performance, reliable connection and convenient assembly.

Particularly, the male terminal is provided with a bending limiting piece extending out of the male rubber shell, the male rubber shell is provided with a limiting groove matched with the bending limiting piece, and the bending limiting piece is clamped in the limiting groove and forms clamping matching of the male terminal and the male rubber shell. The bending limiting piece of the male terminal is connected with the male rubber shell in a clamping matching mode, so that the male terminal can be prevented from loosening and falling, and the male terminal can be connected with the male rubber shell more compactly.

Particularly, the female rubber shell on be provided with the pothook, the one end of this pothook has and presses the splenium, the other end of pothook has the hook, the public rubber shell on correspond hook department and be provided with the groove of stepping down, and step down and be provided with the card hole in the groove, the hook extend and step down the inslot and the block is in the card hole, and constitute the buckle connection cooperation of pothook and public rubber shell. The hook body of the clamping hook is arranged in the yielding groove of the male rubber shell, and the clamping hook cannot be loosened from the clamping hole due to mistaken touch, so that the male rubber shell and the female rubber shell can be more compactly connected.
