Abstract

The invention relates to a safety socket. The safety socket comprises metal clamp plates, clamp plate elastic-clamping mechanisms, transition plates, and transition plate reset mechanisms, wherein a first conductive contact plate and a second conductive contact plate are arranged on two sides of the transition plates respectively. Normally (the socket is not plugged with a plug), a safety electric gap is reserved between each transition plate and one electrified power binding post. When the plug is inserted and connected with the first conductive contact plates through the metal clamp plates and the clamp plate elastic-clamping mechanisms, the inserting force is large enough to overcome elasticity of the transition plate reset mechanisms so as to allow the transition plates to approach the power binding posts, second conductive contact plates contact with the power binding posts, the plug is electrified, and the plug is kept in the state through the clamp plate elastic-clamping mechanisms; a foreign matter is inserted, electrical shock occurs only when the elasticity of the transition plate reset mechanism is overcome; when the elasticity is large enough, shock accidents in children are avoided.

Description

Safety socket

Technical field

The present invention relates to a kind of supply socket, particularly a kind of have can prevent that foreign matter is inserted into charged position in the socket and causes the safety socket of electric shock accidents.

Background technology

Along with expanding economy, development of technology, the raising of living standards of the people, the electrical appliance in the resident family is more and more, therefore the socket that uses also is more and more.The structure of common socket generally comprises housing and is arranged on the electrode of being made by metal material in the housing, match with the plug pole piece, and position corresponding with electrode on the housing is provided with socket aperture.But socket still all exists dangerous hidden danger; namely the socket aperture owing to existing socket all opens wide; and children are full of curiosity; take thing to remove to disclose socket aperture through regular meeting, make if the thing of taking is electric conducting material, just probably can go out casualty accident; therefore; to socket security requirement more and more higher, American-European countries particularly, requirement can still can avoid occurring electric shock accidents when foreign matter inserts socket with certain insertion force.

Summary of the invention

The objective of the invention is to provides a kind of and can prevent that children from taking bonding jumper to disclose to stab socket aperture to touch the safety socket that electric shock accidents is caused at charged position in the socket for overcoming the deficiencies in the prior art.

In order to achieve the above object, the invention provides a kind of safety socket, comprise housing and be arranged on many groups conductive contact film and the power-line terminal that matches with the plug pole piece in the housing, housing is provided with socket aperture, described clamp assembly is arranged on the position with the corresponding below of socket aperture, it is characterized in that: be fixed with the clamping element mounting panel in the described housing, the clamping element mounting panel is provided with many group clamp assemblies, every group of described clamp assembly comprises a pair of metal intermediate plate of setting up relatively and intermediate plate elasticity clamp system, described intermediate plate elasticity clamp system makes the metal intermediate plate of setting up relatively have a flexible clamping force, position on the described clamping element mounting panel between the corresponding metal intermediate plate is provided with the jack that passes for the plug pole piece, described clamping element mounting panel is provided with rebound and rebound resetting device with respect to the opposite side that is provided with clamp assembly, be provided with first conductive contact film that matches with the plug pole piece towards clamping element mounting panel one side on the described rebound, described rebound is provided with second conductive contact film towards power-line terminal one side, described first conductive contact film and 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, leave the secured electrical gap between described power-line terminal and the rebound, described rebound resetting device makes described rebound under normal conditions and keeps the secured electrical gap between the rebound.

Compared with prior art, safety socket of the present invention is by arranging rebound and the rebound resetting device that metal intermediate plate and intermediate plate elasticity clamp system and both sides are respectively equipped with first conductive contact film and second conductive contact film, remain with the secured electrical gap between when not inserting as yet (be plug) rebound and the charged power-line terminal under the normality, when plug inserts through metal intermediate plate and intermediate plate elasticity clamp system with after first conductive contact film is connected, the elastic force that has only the strength of insertion to be enough to overcome the rebound resetting device makes rebound close to power-line terminal, second conductive contact film contacts with power-line terminal, plug gets electric, and relies on intermediate plate elasticity clamp system to keep this state; When foreign matter inserted, the elastic force that need overcome the rebound resetting device equally just can get an electric shock, and when this elastic force is enough big, just can avoid occurring the accident of children from getting electric shock.

The invention will be further described below in conjunction with the drawings and specific embodiments.
