Fig. 3 is the structure cutaway view of the utility model pin socket.

Five, embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Provide by Fig. 1-Fig. 3, the utility model comprises latch and socket, said latch is, the first bolt contact 3a and the second bolt contact 3b that stretch out the latch housing are arranged in the latch housing 1, between two bolt contact magnet 2 is arranged, the solid screw 4a of first lead, the solid screw 4b of second lead are arranged respectively on the first bolt contact 3a and the second bolt contact 3b, the latch earth connection contact 12 that stretches out the latch housing is arranged in the latch housing; Said socket is, on the Socket casing 5 contact apertures is arranged, the first bolt contact 3a and the second bolt contact 3b corresponding first middle contact 7a with latch are arranged in the contact apertures, contact 7b in the middle of second, have between contacts in the middle of two with the latch housing in the magnet 2 corresponding armature 6 that are wound with thrust spring 15, armature is contained on the insulation framework 10, the insulation framework two ends have the first power contact head 8a and second source contact 8b respectively, first power contact head is connected with binding post 14 respectively with the second source contact, and the outlet ground line 11 that stretches out the Socket casing outside is arranged on the binding post.

In order to guarantee result of use, said magnet 2 is high suction magnet (neodymium iron borons); Said armature 6 is fixed on the insulation framework 10 through rivet 16; The first power contact head 8a in the said Socket casing is connected with binding post 14 through anti-crooked plait copper cash 9 respectively with second source contact 8b; Said outlet ground line 11 links to each other with the outlet ground line contact 13a, the 13b that expose Socket casing; Contact 7a, the second middle contact 7b, the first power contact head 8a, second source contact 8b, latch earth connection contact 12, outlet

ground line contact

13a, 13b all are surface contact structures in the middle of the said first bolt contact 3a and the second bolt contact 3b, first; There are power supply beacon lamp (not drawing among the figure) and latch to connect beacon lamp (not drawing among the figure) on the said socket.

Operation principle of the present utility model is: latch inserts socket; With contact 7a in the middle of the first bolt contact 3a and the second bolt contact 3b and first, contact 7b contacts in the middle of second, latch earth connection contact 12 contacts (directly linking to each other) with outlet ground line contact 13a or outlet ground line contact 13b, magnet 2 attracts armature 6, the first power contact head 8a, second source contact 8b is fixed on the two ends of insulation framework 10, insulation framework then is fixed on above the armature 6 by rivet, the first power contact head 8a, second source contact 8b, insulation framework is followed armature 6 and is slided, this moment is because under magnet 2 attraction armature 6 situations, contact 7a closure in the middle of the first power contact head 8a and first, contact 7a communicates with the first bolt contact 3a closure again in the middle of first, contact 7b closure in the middle of the second source contact 8b and second, contact 7b communicates with the second bolt contact 3b closure again in the middle of second, each forms a power circuit, latch is extracted, the first bolt contact 3a, contact 7a in the middle of the second bolt contact 3b and first, contact 7b separates in the middle of second, latch earth connection contact 12 separates with outlet ground line contact 13a or outlet ground line contact 13b, magnet 2 is away from armature 6, pushed back armature 6 by thrust spring 15 this moment, the first power contact head 8a, second source contact 8b, insulation framework is followed armature 6 and is slided, contact 7a separates in the middle of the first power contact head 8a and first, contact 7b separates in the middle of the second source contact 8b and second, contact 7a in the middle of first, do not have above the contact 7b in the middle of second voltage is arranged, to reach protection against electric shock danger, the utility model waterproof, protection against electric shock, simple in structure, novel unique, economic and social benefit is remarkable.
