Embodiment

Describe performance of the present utility model in detail below in conjunction with accompanying drawing:

1,2,3,4,5,6,7,8,11,12,13,14 is the hard contact reed among the figure, 9,10,26 is conductive copper sheet, 15 is holddown groove, 16 are the insulation jacking block, and 17,18,19,20,27,28 is lead, and 21 is that shell, 22 is jack, 23 are the insulation elastic cylinder, 24 insulation elastic cylinder jacks, 25 is base, 29 is plug.

From accompanying drawing 1,2 as can be known: the utility model anti-electric shock socket can be made into two holes, three holes or mixing (combination) socket.

From Fig. 3, Fig. 4, Fig. 5 as can be known: when plug 29 inserts conductive copper sheet 9,10, the power of should the inserting jacking block 16 that will insulate is pushed the

hard contact reed

2,4,6,8 of both sides respectively to, make

hard contact reed

2,4,6,8 and 1,3,5,7 conductings of hard contact reed, because of hard contact reed 1,5 connects power supply, thereby realize power turn-on.The utility model can only use pair of metal contact reed at each jack in design, also can reach the effect of protection against electric shock, and this design should be thought a kind of equivalent of the present utility model.

When wire inserts conductive copper sheet 9,10 (diplopore), can't push insulation jacking block 16 to two ends because of the wire volume is little, therefore can't realize power turn-on, reach the purpose of protection against electric shock.

When sheet metal inserts conductive copper sheet 9 or 10 (single hole), though pushing open, sheet metal pushes insulation jacking block 16 to two ends, but lead 17,18 turns to the

hard contact reed

2,3 or the

hard contact reed

6,7 of opposite side with connection, so can't realize power turn-on, reaches the purpose of protection against electric shock.

From accompanying

drawing

6,8 as can be known: when plug 29 inserts conductive copper sheet 9,10 o'clock, the power of should the inserting jacking block 16 that will insulate is pushed the hard contact reed 2 of both sides respectively to, 4,6,8, make

hard contact reed

2,4,6,8 with

hard contact reed

1,3,5,7 conductings, simultaneously plug 29 elastic cylinder 23 that will insulate is pressed in the elastic cylinder jack 24 that insulate, insulation elastic cylinder 23 is by the hard contact reed 12 on the insulation jacking block 16,14 are communicated with hard contact reed 11,13, because of hard contact reed 1 is connected by lead 27 with hard contact reed 12, hard contact reed 5 is connected by lead 28 with hard contact reed 14, thereby realizes power turn-on.

In like manner as can be known: when wire or sheet metal insert conductive copper sheet 9,10, because of insulation elastic cylinder 23 no external force press down, can't conducting hard contact reed 11,13, so can't realize power turn-on.

In like manner as can be known: when the utility model protection against electric shock Three-hole socket wire or sheet metal insert conductive copper sheet 9,10 from accompanying

drawing

7,8, because of hard contact reed 12,14 that can only another jack of conducting, can't conducting hard contact reed 11,13 (external power supply), therefore can't realize power turn-on; When plug inserts

conductive copper sheet

9,10,26 simultaneously, can realize power turn-on.

Need to prove: to those of ordinary skill in the art, can also make some changes or distortion to the utility model under the prerequisite that does not change the utility model principle, this belongs to protection range of the present utility model equally.
