I.e., a device that connects two active devices, carrying a current or signal. The male terminal and the female terminal can transmit information or current after being contacted.

The connectors of the related art are usually in a set of two, and include a male terminal 5 and a female terminal 4 made of plastic, into which corresponding metal terminal members are respectively inserted. Referring to fig. 1, public end 5 and female end 4 are pegged graft each other and are cooperated, and female end 4's upper end integrated into one piece has hasp piece 2, and hasp piece 2 includes preceding knot portion 21, supporting part 22 and receives portion 23, and supporting part 22 is connected in the connector upper end, and preceding knot portion 21 is a style of calligraphy with receiving portion 23 and sets up in the upper end of supporting part 22, presses receiving portion 23 and can make preceding knot portion 21 perk. The front buckle part 21 extends towards the insertion matching direction, and a triangular reverse buckle 211 is integrally formed at the bottom of the extending end; the upper end of the male end 5 is integrally formed with a triangular fixing block 51, and the end surfaces of the reverse buckle 211 opposite to the fixing block 51 are inclined surfaces. When the mutual grafting cooperation of public end 5 and female end 4, back-off 211 contacts and extrudees with the inclined plane of fixed block 51 each other, extrudees lock catch spare 2 towards the upper end, and after back-off 211 crossed fixed block 51, lock catch spare 2 recovered under the elastic action for back-off 211 left hand thread fixed block 51 makes public end 5 and female end 4 difficult along the separation of grafting direction, thereby realizes the reciprocal anchorage of two connector.

With respect to the related art in the above, the inventors consider that: many connectors are small in size, and when two connectors are manually plugged, fingers press the whole connector, so that the locking fastener is easily pressed. After the locking fastener is pressed by fingers, the stress between the reverse buckle and the fixed block is increased when the reverse buckle and the fixed block are in splicing fit, so that the reverse buckle and the fixed block are easily abraded, and the service life is influenced.
