Description

A kind of socket

Technical field

The utility model relates to a kind of socket.

Background technology

Conduction on the existing socket pegs graft to press from both sides two kinds usually, and a kind of is to bend the pin that the elasticity that produces is come the clamping plug by self; The conduction grafting folder of another kind of multiple socket is to be made of a public moving contacting plate and several quiet contact chips, compresses public moving contacting plate by a spring, and itself and several static contacts are reclined.The shortcoming that above-mentioned two kinds of sockets exist is: for the former, in use for some time, the folder of pegging graft has distortion, and elasticity reduces, and influence contacts with plug; For the latter, a plurality of plugs of pegging graft at the same time, and the thickness of the pin of each plug is not simultaneously, and thin pin has the phenomenon of loose contact.In addition, the ground connection grafting folder on the existing socket also is to bend the pin that the elasticity that produces is come the clamping plug by self, the problem that it can deform after equally also existing use a period of time, elasticity reduces.Loose contact after plug and socket are pegged graft can make the electrical equipment often outage in use and the useful life of shortening socket.

The utility model content

The purpose of this utility model is to provide a kind of socket, and the conduction that it possessed is pegged graft to press from both sides with ground connection grafting folder and can be guaranteed to contact with the pin of plug reliably.

For achieving the above object, the utility model adopts following scheme: a kind of socket, include the cover plate of tool jack and the base of tool cavity, being furnished with conduction grafting folder and ground connection pegging graft in base presss from both sides, conduction is pegged graft to press from both sides by quiet contact chip, moving contact head and spring and is constituted, quiet contact chip is fixed on the base, and moving contact head and quiet contact chip recline, an end of spring and the outside of moving contact head against the inwall of, the other end and base against; Ground connection is pegged graft the outside of folder against spring is arranged, the other end of spring and the inwall of base against.

By such scheme as seen, the moving contact head of folder has spring to compress because each conduction is pegged graft, and ground connection peg graft the outside of folder have spring against, conduction peg graft folder, ground connection pegging graft is clipped in the pin of plug when pegging graft, it is reliable to guarantee to contact with each other; In addition, the socket that the utility model provides is as the multiple socket, a plurality of plugs of pegging graft at the same time, and the thickness of the pin of each plug is not simultaneously, because the pin of each plug is independently to peg graft with each conduction grafting folder and ground connection grafting folder, therefore, the pin that approaches does not have the phenomenon of loose contact yet.

The utility model is rational in infrastructure, use is reliable, and it is good to guarantee to contact with each other after it and plug are pegged graft, and its long service life.

Embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, Fig. 2, the utility model possesses the cover plate 1 that tool jack 1a, jack 1, jack 1c are arranged and the base 2 of tool cavity.

Referring to Fig. 2, in base 2, be furnished with some ground connection grafting folders 6 and conduction grafting folder, conduction is pegged graft and is accompanied two kinds, a kind of is to be made of quiet contact chip 3, moving contact head 4 and spring 5, another kind is to be made of quiet contact chip 3, moving contact head 10 and spring 5, the used quiet contact chip 3 of conduction grafting folder of each homopolarity is connected to an integral body, and the quiet contact chip 3 of public a slice is pressed from both sides in each the conduction grafting that promptly is in homopolarity, and quiet contact chip 3 is fixed on the base 2 by screw 12.Each spring 5 is resisted against the outside of each moving contact head 4, moving contact head 10, the inwall of the other end of spring 5 and base 2 against.Ground connection is pegged graft the outside of folder 6 against spring 7 is arranged, the inwall of the other end of spring 7 and base 2 against.Pegging graft ground connection is connected with lead 11 between the folder 6, and wherein the ground connection folder 6 of pegging graft also is connected on 16, the two quiet contact chips 3 of lead that are used for ground connection and is connected to lead 13.

In conjunction with Fig. 1, Fig. 2 as seen, each jack on the cover plate 1 respectively with base 2 on each ground connection folder 6 and conduction folder of pegging graft of pegging graft corresponding one by one.

Referring to Fig. 3, ground connection is pegged graft folder 6 for being similar to " Ω " shape, presss from both sides 6 two outsides all against spring 7 is arranged ground connection pegging graft.

Referring to Fig. 2, Fig. 4, the slot 4a that the middle part of moving contact head 4 has depression, this moving contact head 4 is applicable to the columniform pin of pegging graft with the conduction grafting folder that quiet contact chip 3 and spring 5 constitute.

Referring to Fig. 2, Fig. 5, moving contact head 10 is for sheet material is converted into, and this moving contact head 10 is applicable to the flat pin of pegging graft with the conduction grafting folder that quiet contact chip 3 and spring 5 constitute.

Referring to Fig. 2, Fig. 6, an end of quiet contact chip 3 is fixed on the base 2 by screw 12.
