Abstract

The invention discloses a power supply socket which is convenient to use and can radically prevent children from plugging foreign matters into jacks by mistake. The power supply socket comprises an upper cover and a lower cover, wherein at least one set of jacks is arranged on the upper cover, and each set of jacks comprises a phase line jack and a null line jack; the lower cover is internally provided with plug bushes corresponding to each jack; the back face of the upper cover is provided with installing pits corresponding to each set of jacks; each installing pit is communicated with the phase line jack and the null line jack in the corresponding set of jacks; a pair of protection sheets capable of sliding relative to each other is arranged in each installing pit; and an offsetting spring is arranged between the outer side end surface of each protection sheet and the side wall of the corresponding side of each installing pit. The power supply socket eliminates the safety hidden trouble and is approved by the American Electric Safety Association.

Description

Supply socket

Technical field

The present invention relates to supply socket, refer more particularly to and to prevent that children from inserting 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 higherly fixed.So just make this supply socket in normal use, the plug plug is very hard; In fact, this supply socket can not fundamentally stop children that foreign matter is mispluged into jack.Therefore, still there is potential safety hazard in this supply socket.

Summary of the invention

Technical problem to be solved by this invention 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 used in the present invention is: 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 slide relative in the pit, is provided with back-moving spring between the sidewall of a corresponding side of the outside end face of each screening glass and arrangement pit.

Described screening glass comprises: floating seat; the both sides of floating seat are provided with a pair of leading arm that is parallel to each other; wherein; the end of a leading arm is provided with linking arm; the end of linking arm is provided with the door shield piece; the door shield piece is provided with guide ramp; the end of another leading arm is provided with the guide table involutory with linking arm; two screening glass are involutory mutually; the door shield piece of a screening glass is slidingly arranged between a pair of leading arm of another screening glass, and the linking arm of a screening glass is slidingly arranged on the guide table of another screening glass.

The outside end face of described floating seat is provided with column, and described back-moving spring is sleeved on the column.

The invention has the beneficial effects as follows: this screening glass method to set up of the present invention, 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 invention in detail.

As Fig. 1, shown in Figure 5, supply socket of the present invention, 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 12, a zero line jack 11 and an earth jack 13, be provided with in the lower cover 2 two groups respectively with line jack 12 mutually, zero line jack 11 and earth jack 13 corresponding sleeves 6---referring to shown in Figure 3, as shown in Figure 7, 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 12 and zero line jack 11 in the respective sets jack---referring to shown in Figure 7, but each settles the screening glass 3 that is provided with a pair of slide relative in the pit 14, as shown in Figure 4, its structure comprises: floating

seat

31,31 both sides of floating seat are respectively arranged with first leading arm 32 and second leading arm 33, first leading arm 32 and second leading arm 33 are parallel to each other, the end of first leading arm 32 is provided with linking arm 34, the end of linking arm 34 is provided with door shield piece 36, door shield piece 36 is provided with guide ramp 361, the end of second leading arm 33 is provided with the guide table 35 involutory with linking arm 34, two screening glass 3 are involutory mutually, as shown in Figure 6, the door shield piece 36 of a screening glass 3 is slidingly arranged between first leading arm 32 and second leading arm 33 of another screening glass 3, the linking arm 34 of a screening glass 3 is slidingly arranged on the guide table 35 of another screening glass 3, the outside end face of floating seat 31 is provided with column 311, be set with back-moving spring 4 on three-dimensional 311, the outer end of back-moving spring 4 is resisted against on the sidewall of a corresponding side of settling pit 14; In the present embodiment, described lower cover 2 is provided with eight plug wire holes 21 and five terminals 22---referring to shown in Figure 2.
