Description

Closed socket

The utility model relates to the supply socket that a kind of electric equipment is connected with power supply, particularly a kind of closed socket.

Supply socket is connected and disengagement with plug, makes various electric equipments switch on or off power supply, is a kind of electric elements that generally use, and almost is that various electric equipments are requisite.The present socket that uses, all be by base, various conductive pieces on loam cake and the base are formed, on covered two or three jacks, the electrically conductive elastic plug-in unit that clamps inserted sheet is housed on base and the corresponding position of above-mentioned jack, inserted sheet on the plug inserts to be realized in the electrically conductive elastic plug-in unit being electrically connected, and transfers to plug, and then the power supply of electric equipment is cut off.Above-mentioned socket exists following shortcoming: the first, because the electrically conductive elastic plug-in unit is exposed in the surrounding environment, the dust in the absorbed air in the more place of the relatively poor dust of environment, causes short circuit, generation equipment or personal injury easily easily.The second, in electric equipment and the more occasion of socket, employed lead or metal device are strayed into easily to cause in the socket aperture and get an electric shock or equipment breakdown; The 3rd, children, blind person and when using socket in the dark might touch the electrically conductive elastic plug-in unit in the socket aperture, cause electric shock accidents.

The purpose of this utility model is to overcome above-mentioned deficiency and proposes a kind of improved supply socket, and it has the dust of preventing and falls in the socket, prevents to touch the electrically conductive elastic plug-in unit in the socket and the function that causes electric shock.

The utility model provides a kind of closed socket, it comprises base, loam cake and base-mounted electrically conductive elastic plug-in unit, on cover and have endoporus, be equipped with in the endoporus and can make the directed slide block that moves within it, along the slide block moving direction certain clearance is arranged between slide block and the endoporus, have jack on the slide block, the quantity of the electrically conductive elastic plug-in unit on the quantity of jack and layout and the base and arrange corresponding, restricted its string gland with holes moving and that be connected with base and loam cake upwards on the slide block.

The compression spring that is fixed with one is with it arranged on the above-mentioned slide block, and after slide block was packed in the endoporus, compression spring placed in the slotted hole that the endoporus edge opened.

Between above-mentioned slide block and the endoporus along the gap of slide block moving direction, when being in sealing conduction elastic plugin for slide block, the distance at the center of the jack of opening and electrically conductive elastic plug-in unit center on it.When inserting the inserted sheet moving slider, when collided in end of slide block and endoporus edge, the jack on the slide block just in time with electrically conductive elastic plug-in unit centering.

In the time attaching plug will being inserted socket, inserted sheet is inserted open on the slide block in the jack earlier along the direction moving slider of compression spring compression, inserted sheet is inserted in the electrically conductive elastic plug-in unit after making inserted sheet aligning electrically conductive elastic plug-in unit, get final product energized.

Advantage of the present utility model is as follows:

1, when the inserted sheet of plug does not insert socket, the electrically conductive elastic plug-in unit on the base not with slide block on jack centering, so outside the electrically conductive elastic plug-in unit is not exposed to,, be a kind of safe and reliable supply socket to preventing the good effect of getting an electric shock;

2, can avoid conductive materials (as dust, water effectively, corrosive gas and metal object etc.) fall into or be adsorbed on the electrically conductive elastic plug-in unit, prevent the short circuit accident that causes thus, be specially adapted under the more and moist environment of dust, use, also be specially adapted to the blind person and have child's family to use.

3, only need existing socket is done very little change, cost increases a bit a little, and manufacturer just can produce under existing working condition.
