Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, Fig. 2 and a kind of plate shown in Figure 3, comprise housing 1, switch 2, metal contact element and a pair of metal pin 3 for the access power supply.Metal pin 3 is arranged on housing 1, and housing 1 back side is stretched out in metal pin 3 outer ends, and it is inboard and connects respectively the metal contact element of correspondence by wire that housing is stretched in metal pin 3 the inners.
Three socket 4, three sockets 4 that housing 1 front is provided with for three pin plug plugs comprise ground connection socket, neutral receptacle and line receptacle.Offer button hole on the housing front of three socket 4 tops, switch 2 is arranged in housing 1, and the button on switch 2 is on button hole and stretches out outside housing 1.Be that housing 1 top is respectively equipped with anti-skidding striped 11 in button hole both sides, the anti-skidding striped 11 at every place is all that part is on housing 1 front, part along and housing 1 two sides.Housing 1 two sides are provided with two sockets 5 for two pin plug plugs.
As shown in Figure 2, in enclosure interior, corresponding be respectively equipped with three insulation square boxs 43 on the housing 1 of three socket inboards, metal contact element comprises pair of metal bending contact and a plurality of socket contact device.Pair of metal bending contact is divided into metal folding contact 51 and lower metal folding contact 52, the concrete quantity of socket contact device is two or three, two socket contact devices wherein comprise the first socket contact device 41 and the second socket contact device 42 that is in neutral receptacle that is in line receptacle, can establish a socket contact device in the ground connection socket, also can not establish.
The first socket contact device 41 is arranged in insulation square box 12 corresponding to line receptacle, and the second socket contact device 42 is arranged in insulation square box 12 corresponding to neutral receptacle.The square metal sheet frame that the first socket contact device 41 and the second socket contact device 42 are pin contact flat spring and bottom by top consists of.
As Fig. 2 and shown in Figure 4, upper metal folding sheet 51 is identical with lower metal folding contact 52 shapes, is all to be connected as a single entity by bending contact-segment 5d, contact-segment 5a, bending changeover portion 5e, noncontact section 5b and oblique contact-segment 5c successively to consist of.Upper metal folding contact 51 connects the first socket contact device 41 by the contact-segment 5a on it, lower metal folding contact 52 connects the second socket contact device 42 by the contact-segment 5a on it, the contact-segment 5a that namely goes up metal folding contact 51 is in the square metal sheet frame on interior contact the first socket contact device 41 of insulation square box 12 corresponding to line receptacle, noncontact section 5b is in insulation square box 12 outsides corresponding to neutral receptacle, these insulation square box 12 isolation noncontact section 5b and second socket contact devices 42.The contact-segment 5a left end of upper metal folding contact 51 passes insulation square box 12 corresponding to line receptacle, connect bending contact-segment 5d, contact-segment 5a right-hand member passes insulation square box 12, and connects noncontact section 5b by bending changeover portion 5e, and noncontact section 5b right-hand member connects oblique contact-segment 5c.Lower metal folding contact 52 is opposite with the setting position of upper metal folding sheet 51, repeats no more.The two ends of wherein going up metal folding sheet 51 and lower metal folding sheet 52 are all bending contact-segment 5d or oblique contact-segment 5c, and bending contact-segment 5d and oblique contact-segment 5c equal corresponding position are in two two socket 5 positions of housing 1 both sides.
