Abstract

The utility model relates to a novel safety socket. A slide groove is dented inwards on one shorter side of a jack portion for an upper and a lower slide blocks to be inserted after combined. The top of the jack portion is penetrated with a power supply jack for inserting pieces at the front end of a plug to be inserted; a right blocking and stopping rib, a left blocking and stopping rib and a supporting rail rib are respectively arranged at the proper positions of the inner slide groove; compression springs are respectively contained between the right blocking and stopping rib and the right blocking and stopping rib and between the upper slide block and the lower slide block to make the upper slide block and the lower slide block slide in the jack under the action of spring and push and have the efficacy of protecting the interior of the socket when no inserting piece is inserted. Once a foreign matter is inserted from any one power supply jack, the foreign matter can be obstructed by one of the slide blocks not to be inserted.

Description

The new type of safe socket

The utility model system provides a kind of new type of safe socket, refers to a kind of socket of protecting especially when the inserted sheet of no plug is planted, and its feasible supply hub that covers is invaded to avoid foreign matter, belongs to electric equipment products.

As everyone knows, the plant in general household electrical appliance or the work field boundary institute all need utilize one to be connected on the jack of socket from the wire and plug that this equipment extends, and power supply is entered in this equipment via electric wire and makes it produce the function of expection; So in the epoch that today, quality of the life improved constantly, under the situation that people raise year by year for the utilization rate of electrical appliance, the demand of socket also increases day by day, and is widely used in every field.

Usually socket is normally placed in apart from the wall about about half chi to a chi in ground, to be convenient for people to use, yet, can provide easy-to-use part though commonly use socket, but because its jack long term exposure is in the outside, provide the live wire of electric current pin end and be provided with in its hole, if invading, foreign matter (as flying dust or moisture content etc.) very easily cause the impaired of electric power system or electric leakage situation to take place, especially the child in the family stretches in the jack of socket and causes electric shock accidents owing to the cause of curiosity often will have conductive metal sharp shaped material (as pin, awl or the like).So someone designs a kind of wall socket protector, this device ties up to and sets up a lid outside the socket on the framework, cover socket by this lid, open lid when treating to utilize socket again and plant, make socket when user mode not, can avoid foreign matter and invade, but this device still has a shortcoming for plug, promptly, when the people opens lid and only need use wherein a socket, outside its socket that is arranged in two ends, the left and right sides is still and is exposed to, the danger that still has foreign matter to invade or to get an electric shock;

The structure that a kind of socket protective lid is arranged again; it ties up to the over cap of planting on each socket; when will using this socket, people to be had then utilize one to pull out the instrument of lid and lever up over cap and get final product; then treat again over cap to be covered when plug pulls away socket; yet; though this kind structure can reach the purpose of each socket of protection; and have a shortcoming during actual the use; promptly pulling up over cap each time all needs one to pull out the instrument of lid and can finish; very inconvenience in the use, and pull up the over cap that comes and very easily lose, often when breaking away from socket, can't seek by plug; not only cause user's puzzlement, and cause the supply hub of socket to be exposed to the shortcoming in the outside once again simultaneously.

In order to overcome above-mentioned deficiency; the purpose of this utility model is: a kind of new type of safe socket is provided; this safety socket system is improved design with regard to the structure of the jack portion of socket; make it not only possess the original function of socket; and can protect socket inside not invaded by foreign matter simultaneously, prevent Danger Electric shock risk.

A kind of new type of safe socket of the utility model, this socket lies in the jack portion chute that wherein sets to the concave on the shorter lateral sides of such, fill in the lump after keeping supplying the combination of slide block and sliding block, and being equipped with in jack portion end face can be for a pair of supply hub of plug head inserted sheet insertion, and in inner chute height appropriate position, space up and down, be respectively equipped with right stopping rib, left stopping rib and supporting rail rib, then dispose a support bar on this right side stopping rib and the left stopping rib respectively, be nested with fixing respectively for the compression spring.

Wherein, vertical section of top shoe generally is

Shape, it has preceding plate and back plate, wherein, back plate is a flat cuboid, its end face be equipped with one can for inserted sheet place on draw jack, draw first guiding face that then is arranged with the tool inclination in the jack downwards on this, and wherein a minor face lateral margin faces down and establishes tool and become a L template, then convex with a support bar on the root edge face of this L template, again, preceding plate is to be arranged in plate tail end root edge place, back.

Wherein, sliding block is flat cuboid, its end face central authorities and closely wherein one than being concaved with a depressed part between minor face, these depressed part central authorities then are equipped with a following jack that draws that can supply inserted sheet to place, and another is provided with than minor face lateral margin face place and draws slot, this groove face that draws slot then is concaved with second guiding face of tool inclination downwards, and be provided with a recessed groove between slot to drawing in the depressed part limit, the bottom land system of this recessed groove is connected with depressed part and forms an aperture, then be respectively equipped with right groove and left groove on the two longer sides lateral margin faces, and convex with a support bar on the wherein groove face of right groove.

The utility model has the advantages that:

One, the inner seal cavity that forms of socket, when no plug head inserted sheet plant, can with external isolation, effectively prevent the invasion of dirt, flying dust and moisture content.

Two, when only inserting arbitrary supply hub of jack portion with (non-a pair of) sharp shaped material, then be subjected to jack portion inside a wherein slide block obstruct and can't insert socket inside smoothly, effectively protect socket inside, avoid causing danger.
