Abstract

The utility model relates to an electrical apparatus element, particularly a plug and a socket with anti-drop function. The plug and socket comprises a plug seat, a protective cover, and an insertion piece arranged on the inner side of the plug through a screw, the outer end of the insertion piece is extended to the outer side of the plug seat, and the outer end of the insertion piece is provided with a lateral projection; the upper end of the protective cover is provided with a lead terminal of a lead wire, and the leading terminal is provided with a clamp hoop; the socket is composed of a socket body and a base plate of the socket, the base plate of the socket is provided with a clamping piece at least through the screw, the shape of the clamping piece is a circular arc which uses the socket body as the center, and the shape of a jack socket is also the circular arc. The anti-drop plug and socket has the advantage of safety, etc.

Description

Drop-proof plug-and-socket

The utility model relates to electric elements, refers in particular to a kind of plug and socket of putting the function that comes off that have.

Existing plugs and sockets is made of with the clamp clip that is installed in the socket the inserted sheet that is installed in the plug usually, during use, inserted sheet is inserted in the clamp clip power connection.This structure is suitable for some relatively-stationary occasions, if on the locomotive that moves, or vibrates on the bigger machine, just not too suitable, its inserted sheet and clamp clip to combine fastness often not enough, very easily become flexible even drop, thereby have influence on the contact performance of switch, cause apparatus failure.

The purpose of this utility model is a kind of drop-proof plug-and-socket of design, to improve the contact performance and the safety and reliability of plugs and sockets.

Its main technical schemes comprises that connector assembly and protective cover surround a cavity, and utilize screw to be installed in plug and sit inboard inserted sheet, the outer end of this inserted sheet extends to the outside of connector assembly, and a horizontal protuberance is arranged in the outer end of inserted sheet, there is wire terminals upper end at protective cover, on this exit bail is arranged; Its socket is made up of jack body and socket base plate, on the socket base plate, utilize screw that a clamp clip is installed at least, each clamp clip is made of two flexure strips that are in contact with one another, its shape is that one section center with jack body is the arc in the center of circle, on the jack body corresponding to the side of each clamp clip, having with the center of jack body is the arc jack in the center of circle, and the arc length of this jack is greater than the arc length of clamp clip, and, wherein have an end of a jack that an outwards outstanding gap is arranged.

The utility model has the advantages that owing to a horizontal protuberance is arranged in the outer end of inserted sheet, jack and clamp clip that one correspondence is arranged on socket, and depart from mutually the position of jack and clamp clip, one gap is also arranged on jack, during use, inserted sheet is inserted in the jack, the protuberance on the jack is aimed at gap, rotation again, the outer end of inserted sheet is inserted in the clamp clip, energized, its protuberance departs from gap; As want to extract inserted sheet, the plug that must reverse again makes inserted sheet break away from clamp clip, its protuberance falls in the gap, plug could be taken out, otherwise, because of the protuberance on the inserted sheet has rotated to the position of departing from gap, cause protuberance to be blocked and can't pull the plug out of the socket by the upper surface of jack body.Therefore, this device is applicable to the more violent occasion of vibration, and its fail safe and reliability are all fairly good.Secondly, after being provided with a bail on the plug, can improve the connection fastness of lead.

Fig. 1 is the structure chart of utility model.

Fig. 2 is plug construction figure.

Fig. 3 is the A-A figure of Fig. 1.

As shown in the figure: plug is made of connector assembly 6 and protective cover 8, and surround a cavity, utilizing screw 7 is symmetrical centre in the inboard of connector assembly 6 with the center of connector assembly 6,3 inserted sheets 5 are installed equably, the outer end of each inserted sheet 5 extends the outside of connector assembly 6, and one of them is the zero line inserted sheet, and in the outer end of this inserted sheet a horizontal protuberance 10 is set, in the upper end of protective cover 8 is wire terminals 12, and bail 9 is arranged on exit 12; Socket is made up of socket base plate 2 and jack body 1, center with socket base plate 2 on socket base plate 2 is a symmetrical centre, utilize screw 4 that 3 clamp clips 3 corresponding with above-mentioned inserted sheet 5 are installed, each clamp clip 3 is made up of two resilient sheet metals that are in contact with one another, clamp clip 3 to be shaped as with the center of socket base plate 2 be one section arc in the center of circle, on jack body 1 corresponding to the side of the position of 3 clamp clips 3, have 3 to be the arc jack 11 of symmetrical centre equally with the centers of jack body 1, have on the zero line jack therein one with the zero line inserted sheet on protuberance 10 corresponding gap 13.
