electrical connector

【Technical field】

The utility model relates to an electric connector, in particular to an electric connector which can prevent the butt connector from loosening.

【Background technique】

Chinese Utility Model Patent No. 01280614.5 discloses an electrical connector, which mainly includes an insulating body, a conductive terminal module held on the insulating body, and a shielding case. Wherein the butt joint surface of the insulating body is concavely provided with a socket to accommodate the butt connector, and a channel is provided on the side wall adjacent to the butt joint surface on the insulating body, and the front end of the channel runs through the outer wall surface of the side wall, and the channel Protruding projections are protruded from the junctions between the adjacent butt joint surface and the outer wall surfaces of the side walls on the two side walls, and the two projections are opposite to each other. When the docking connector is inserted into the socket of the electrical connector, the latching arm provided on the docking connector moves downward until the stopper on the latching arm passes over the bump, and then the latching arm returns, and the latching arm on the latching arm Resisted by the bumps, allowing the mating connector to be retained. To pull out the mating connector, you only need to press the buckle arm so that the stop part is out of the resistance of the bump.

However, pressing the clasp arm too frequently may cause the clasp arm to break easily. If the depth of the electrical connector along the mating direction needs to be reduced to accommodate only the front end of the mating connector according to customer requirements, the stopper of the latching arm and the protrusion of the electrical connector cannot resist each other after the mating connector is inserted. Therefore, it is necessary to design a new type of electrical connector.

Please refer to Figures 5 and 6, the docking connector 200 matched with the electrical connector 100 of the present invention includes a base 201, a latching arm 202 extending obliquely upward from the front end of the base 201, and connecting the base 201 and the latching arm. 202 of the connecting portion 203 . Stoppers 204 extend from both sides of the buckle arm 202 , and the stoppers 204 are relatively located above the connecting portion 203 . When the docking connector 200 is inserted into the electrical connector 100, the latching arm 202 is inserted into the groove 123 and the slot 126, and the side wall of the connecting portion 203 interferes with the protruding portion 124 provided in the groove 123; when the docking connector 200 After fully inserted, the connecting part 203 is accommodated in the groove 123, the buckling arm 202 partially extends obliquely into the slot 126, the stopper 204 is located above the protruding part 124, and the protruding part 124 is against the back of the connecting part 203. The end face 205 prevents the mating connector 200 from detaching from the receiving cavity 101 . In this embodiment, the catch portion 204 of the latching arm 202 is located above the protruding portion 124 , that is, the latching arm 202 of the mating connector 200 does not play a latching role, but is held by the protrusion of the electrical connector 100 . The part 124 cooperates with the connecting part 203 to realize the fixing of the two. Of course, the protrusion 124 can also be added on the premise that the existing buckling arm 202 still has a buckling function. Even if the buckling arm 202 breaks accidentally, the protrusion 124 can still resist the connecting portion 203 without causing a butt joint. The connector 200 is loosened, and the force generated by the elastic deformation of the resisting portion 32 of the anti-mistake insert 3 and the force generated by the elastic deformation of the abutting portion 412 of the shielding case 4 can further hold the docking connector 200 .

When you want to pull out the butt connector 200, you can first squeeze the buckle arm 202 downwards. At this time, the two sides of the blocking portion 204 will move downward along the guiding surface 125 of the protruding portion 124, thereby pushing the insulation outward. The main body 1 plastically deforms the insulating main body 1 to release the resistance of the protruding portion 124 to the connecting portion 203 , and safely pulls out the mating connector 200 . Since the interference between the protruding portion 124 and the connecting portion 203 is relatively easy to remove in this embodiment, the mating connector 200 can be pulled out directly without squeezing the locking arm 202, so that the connecting portion 203 can go over the protruding portion 124 and Pull out the docking connector 200 . Since the docking connector 200 in this embodiment can be pulled out directly from the electrical connector 100 without squeezing the locking arm 202, after the electronic device with the electrical connector 100 of the present utility model is connected to the docking connector, its docking When the cable of the connector is pulled by an unexpected large force, the electronic device can be directly disconnected from the docking connector, so as to avoid falling damage due to the inability of the electronic device and the docking connector to be disconnected in time in the prior art, etc. Situation happens.

The above-mentioned implementations are preferred implementations of the electrical connector of the present invention. Of course, the electrical connector of the present invention can also adopt other implementation modes, which will not be repeated here.
