Description
Technical field
The utility model relates to supply socket, refers more particularly to that a kind of children of preventing insert charged jack with the metal species foreign matter and the supply socket of getting an electric shock.
Background technology
Present supply socket prevents that children from inserting the protection mechanism of charged jack with the metal species foreign matter though also have, and when this protection mechanism can only guarantee insertion force less than set point, plug or other foreign matters can not be inserted jack.Because children's strength varies, foreign matter can not be mispluged into jack in order to ensure children, must insertion force is very highly fixed.So just make this supply socket in normal use, the plug of plug is very hard; In fact, even if like this, can not prevent fundamentally that children are inserted into the foreign matter mistake in the jack.Therefore, still there is potential safety hazard in this supply socket.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of easy to use, and can prevent fundamentally that children from mispluging supply socket into jack with foreign matter.
For solving the problems of the technologies described above; the technical solution adopted in the utility model is: a kind of supply socket; comprise: on; lower cover; loam cake is provided with at least one group of jack; every group of jack comprises a phase line jack and a zero line jack; be provided with in the lower cover and the corresponding sleeve of each jack; the back side of described loam cake is provided with and every group of corresponding arrangement pit of jack; each settles pit to communicate with line jack mutually and zero line jack in the respective sets jack; but each settles the screening glass that is provided with a pair of folding in the pit; be provided with back-moving spring between the sidewall of a corresponding side of the outside end face of each screening glass and arrangement pit; settle the top of pit to be provided with cover plate; be provided with guide frame between cover plate and the screening glass, the both sides of cover plate also are respectively arranged with the positive stop that matches with screening glass.
Described screening glass comprises: substrate, and the pilot hole that is symmetrically arranged with lead on the inner side end of substrate and matches with lead, the outside end face of substrate is provided with the spring placement hole concentric with lead; Two screening glass are involutory mutually, and the lead of each screening glass passes from the pilot hole of another screening glass, and described back-moving spring has two pairs, are set in the lead that passes and are inserted in the spring mounting hole; Described guide frame comprises: be arranged on the guiding convex tendon and the gathering sill that matches with the guiding convex tendon that is provided with on the cover plate at substrate back middle part, the guiding convex tendon is slidingly arranged in the gathering sill.
Be provided with respectively on the inner side end of described substrate and the corresponding corresponding guiding surface of jack.
The both sides on the upper and lower surface of described substrate are oblique layout, form " eight " font structure respectively, thereby make between the both sides and loam cake of substrate upper surface, all form the gap between the both sides of substrate lower surface and the cover plate.
The beneficial effects of the utility model are: this screening glass of the present utility model matches with positive stop on the cover plate, guaranteed to have only when inserting jack at the same time and could insert, so just will insertion force not decide very highly, that is: the elasticity of back-moving spring needn't be too big, thereby guaranteed the normal use of this supply socket; Because children are when playing, in unlikely two jacks that two metallic foreign bodies are inserted into simultaneously socket, fundamentally stoped children that foreign matter is mispluged into jack, eliminated potential safety hazard.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As Fig. 1, shown in Figure 2, supply socket described in the utility model, comprise: on, lower cover 1 and 2 and be used for fixing, lower cover 1 and 2 fixed head 9, loam cake 1 is provided with two groups of jacks, every group of jack comprises a phase line jack 11, a zero line jack 12 and an earth jack 13, be provided with in the lower cover 2 two groups respectively with line jack 11 mutually, zero line jack 12 and earth jack 13 corresponding sleeves, the back side of loam cake 1 is provided with two and settles pit 14, each settles pit 14 to communicate with line jack mutually 11 and zero line jack 12 in the respective sets jack---referring to shown in Figure 4, but each settles the screening glass 3 that is provided with a pair of folding in the pit 14, as shown in Figure 3, the structure of screening glass 3 comprises: substrate 30, the both sides of substrate 30 upper surfaces, the both sides of substrate 30 lower surfaces are oblique layout, form " eight " font structure respectively, thereby make between the both sides and loam cake 1 of substrate 30 upper surfaces, all form the gap between the both sides of substrate 30 lower surfaces and the cover plate 5, the pilot hole 34 that is symmetrically arranged with lead 33 on the inner side end of substrate 30 and matches with lead 33, the outside end face of substrate 30 is provided with the spring placement hole 36 concentric with lead 33, two screening glass 3 are involutory mutually, the lead 33 of a screening glass 3 passes from the pilot hole 34 of another screening glass 3, each lead 33 is set with back-moving spring 4 after passing pilot hole 34, also be fitted with back-moving spring 4 in each spring placement hole 36, the outer end of back-moving spring 4 is pressed on the sidewall of a corresponding side of settling pit 14, the middle part, the back side of substrate 30 is provided with circular arc guiding convex tendon 35, cover plate 5 is provided with circular arc shaped guide slots 51 that matches with the convex tendon 35 that leads and the positive stop 52 that matches with the two ends of substrate 30, and guiding convex tendon 35 is slidingly arranged in the gathering sill 51; One end setting of substrate 30 inner side ends and the zero line jack 12 corresponding perpendicular guiding surfaces 32 of inserting, the other end of substrate 30 inner side ends are provided with and line jack 11 corresponding horizontal slotting guiding surfaces 31 and perpendicular guiding surfaces 32 of inserting mutually.
During use, as long as when two inserted sheets are inserted in phase line jack 11 and zero line jack 12 simultaneously, two screening glass 3 just can separate to both sides simultaneously, make inserted sheet pass between two screening glass 3, insert in the corresponding sleeve; And when having only an inserted sheet to insert, two screening glass 3 are pressed on the cover plate 5 in a side of the jack that is inserted with inserted sheet, and screening glass 3 just is constrained between a pair of corresponding positive stop 52, and can not separate to both sides, thereby plays a very good protection.
