Safety socket
Technical field
The present invention relates to a kind of supply socket, particularly a kind of have foreign matter can be prevented to be inserted into charged position in socket and to cause the safety socket of electric shock accidents.
Background technology
Along with expanding economy, the progress of technology, the raising of living standards of the people, the electrical appliance in resident family is more and more, and the socket therefore used also is more and more.The structure of common socket generally comprises housing and arranges electrode that be made up of metal material in the housing, that match with plug pole piece, and position corresponding with electrode on housing is provided with socket aperture.But socket still all also exists dangerous hidden danger; namely because the socket aperture of existing socket is all unlimited; and children are full of curiosity; thing often can be taken to go to disclose socket aperture, make if the thing taken is electric conducting material, just probably can go out casualty accident; therefore; to socket security requirement more and more higher, particularly American-European countries, requirement can foreign matter with certain insertion force insert socket time still can avoid occurring electric shock accidents.
Summary of the invention
The object of the invention is to for overcoming the deficiencies in the prior art and provide a kind of and can prevent children from taking bonding jumper to disclose stamp socket aperture and touch charged position in socket and cause the safety socket of electric shock accidents.
In order to achieve the above object, the invention provides a kind of safety socket, comprise housing and the many groups conductive contact film and power-line terminal that match with plug pole piece are in the housing set, housing is provided with socket aperture, clamp assembly is arranged on the position of below corresponding with socket aperture, it is characterized in that: in described housing, be fixed with clamping element mounting panel, clamping element mounting panel is provided with organizes clamp assembly more, often organize described clamp assembly and comprise the metal intermediate plate and intermediate plate resilient clamping mechanism relatively set up for a pair, described intermediate plate resilient clamping mechanism makes the metal intermediate plate relatively set up have a flexible clamping force, position on described clamping element mounting panel between corresponding metal intermediate plate is provided with the jack passed for plug pole piece, described clamping element mounting panel is provided with rebound and rebound resetting device relative to the opposite side being provided with clamp assembly, described rebound is provided with the first conductive contact film matched with plug pole piece towards clamping element mounting panel side, described rebound is provided with the second conductive contact film towards power-line terminal side, described first conductive contact film and the second conductive contact film are electrically connected, described power-line terminal is arranged on the below of rebound, described rebound can move setting to power-line terminal, secured electrical gap is left between described power-line terminal and rebound, described rebound resetting device makes described rebound under normal conditions and retain secured electrical gap between power-line terminal, described intermediate plate can be arranged in pairs in opposite directions movably, described intermediate plate resilient clamping mechanism comprises a pair first extension springs, described a pair first extension springs are separately positioned on the two ends of intermediate plate and are between two intermediate plates, and the first extension spring two ends are fixedly connected with both sides intermediate plate respectively and form described intermediate plate resilient clamping mechanism.
Compared with prior art, safety socket of the present invention is respectively equipped with rebound and the rebound resetting device of the first conductive contact film and the second conductive contact film by arranging metal intermediate plate and intermediate plate resilient clamping mechanism and both sides, under normality, (when namely plug not yet inserts) remains with secured electrical gap between rebound and charged power-line terminal, when plug is after metal intermediate plate and the insertion of intermediate plate resilient clamping mechanism are connected with the first conductive contact film, the elastic force only having the strength of insertion to be enough to overcome rebound resetting device makes rebound close to power-line terminal, second conductive contact film contacts with power-line terminal, plug obtains electric, and rely on intermediate plate resilient clamping mechanism to keep this state, when there being foreign matter to insert, needing the elastic force overcoming rebound resetting device just can get an electric shock equally, when this elastic force is enough large, just can avoid the accident occurring children from getting electric shock.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.

Embodiment
As Figure 1-3, safety socket comprises housing and arranges the many groups conductive contact film and power-line terminal 4 that match with plug pole piece in the housing, described housing comprises upper cover 1 and base 2, described socket aperture 5 is arranged on upper cover 1, described clamp assembly 3 is arranged on the position of below corresponding with socket aperture 5, be fixed with clamping element mounting panel 6 in described housing, described many group clamp assemblies 3 are arranged on clamping element mounting panel 6.For pancake clamp assembly 3, often organize described clamp assembly 3 and comprise the metal intermediate plate 301 and intermediate plate resilient clamping mechanism relatively set up for a pair, described intermediate plate resilient clamping mechanism makes the metal intermediate plate 301 relatively set up have a flexible clamping force, is ejected by the power of rebound resetting device to prevent the plug inserted.Position on described clamping element mounting panel 6 between corresponding metal intermediate plate 301 is provided with the jack 601 passed for plug pole piece, and described intermediate plate 301 can be arranged on the both sides of jack 601 in pairs in opposite directions movably.In this specific embodiment, vertical wall 302 is provided with in the surrounding of described jack, described intermediate plate 301 is arranged in pairs between riser 302, described parallel with intermediate plate 301 moving direction, relative riser 302 is arranged with projection 3021, relevant position, described intermediate plate 301 two ends is provided with chute 3011, both sides chute 3011 is slidably fitted in the projection 3021 of both sides and arranges movably in opposite directions described in formation, the setting of certain chute 3011 and projection 3021 also can be conversely, namely projection 3021 is arranged on intermediate plate 301, and chute 3011 is arranged on riser 302.Described intermediate plate resilient clamping mechanism comprises a pair first extension springs 303, described a pair first extension springs 303 are separately positioned on
