Abstract

The utility model discloses a connector assembly with a self-locking function. The connector assembly comprises a male plug and a female receptacle. The female receptacle is provided with openings allowing the male plug to be plugged in. Locking rods penetrate the male plug and can rotate circumferentially. The female receptacle is provided with through holes. A locking end is disposed in each through hole. Each locking end is provided with a round hole and a clamping groove communicated with the corresponding through hole. The shape and the size of the round holes are matched with the shape and the size of the locking rods. When the locking rods are inserted in the through holes, clamping blocks can pass through the clamping grooves. The connector assembly has the advantages that when the male plug is plugged in the female receptacle, self-locking can be achieved, so that the male plug is prevented from being separate from the female receptacle and the firmness of assembly is higher.

Utility model content

The deficiency existing for prior art, it is a kind of with auto-lock function that the purpose of this utility model is to provide, and makes more firmly a kind of connector with auto-lock function of cooperation of male plug part and mother socket.

For achieving the above object, the utility model provides following technical scheme: a kind of connector with auto-lock function, comprise male plug part and mother socket, described mother socket is provided with the opening inserting for male plug part, on described male plug part, be equipped with locking bar and described locking bar can rotate in a circumferential direction, described mother socket is provided with through hole, in described through hole, be provided with keyed end, described keyed end is provided with circular hole and the draw-in groove with the mutual UNICOM of through hole, described circular hole shape size and securing rod shape size are suitable, when described locking bar inserts in through hole, described fixture block can wear draw-in groove.

By adopting technique scheme, when male plug part and mother socket are assembled, male plug part is inserted in the opening of mother socket, on male plug part, be equipped with locking bar, locking bar is provided with fixture block, locking bar can rotate in a circumferential direction, on mother socket, be provided with through hole, in through hole, be provided with keyed end, circular hole and draw-in groove on keyed end, in the time that plug-in unit inserts on mother socket, locking bar is inserted in the through hole of mother socket, rotation locking bar, by the draw-in groove of keyed end in the position alignment through hole of fixture block on locking bar, when fixture block wore after draw-in groove, again rotate locking bar, regulate the position of fixture block, make fixture block leave the position corresponding with draw-in groove, regulate without over-rotation, locking bar just cannot depart from away in through hole, there is the function of self-locking, the whole male plug part assembling is just difficult for from separating with mother socket, the fastness connecting is better, in the process using, increase the functional reliability of male plug part and mother socket.

The utility model is further set to: on described locking bar, be arranged with torsion spring, described torsion spring lower time in the raw, described fixture block and keyed end are inconsistent.

By adopting technique scheme, on locking bar, be arranged with torsion spring, torsion spring is lower time in the raw, fixture block and keyed end are inconsistent, locking bar just cannot wear keyed end, torsion spring has the function of self-recovery, in the time that locking bar is subject to twisting resistance, torsion spring can be out of shape, fixture block is adjusted to behind the position corresponding with draw-in groove, just fixture block can be worn to draw-in groove, twisting resistance disappears, torsion spring automatically restores to original position, fixture block is left on the position corresponding with draw-in groove, keep the inconsistent state of fixture block and keyed end, whole like this locking bar just cannot take off in through hole and depart from, by the setting of torsion spring, make the locking of locking bar more convenient, operate simpler, increase work efficiency.

The utility model is further set to: described locking bar and fixture block are wholely set.

By adopting technique scheme, locking bar and fixture block are wholely set, make structure simpler, easy for installation, not fragile, extend working life, increase work efficiency.
