Abstract

The utility model discloses a universal type general power supply socket. The jacks of the ordinary three-pole receptacle and the contacting end of a contact jaw are made into special shapes to apply to a plurality of three-pole and two-pole power plugs which are commonly and presently used at home and abroad. Various plugs have relatively-fixed inserting positions. Inserting pieces and the contact jaw have enough contact area, and a spring can be arranged on the contact jaw. The contact jaw can adopt a thinner copper sheet after the spring is added, the service life is prolonged, and the raw material is saved.

Description

Universal electric receptacle

The utility model relates to a kind of supply socket, it is characterized in that.Can be applicable to multiple two utmost points and three-terminal polarized plus plug commonly used at present both at home and abroad.

Known supply socket is by socket cover, socket base, intermediate plate (socket contacts the copper sheet of usefulness hereinafter referred to as intermediate plate with inserted sheet), wiring member (wiring copper sheet or binding post are hereinafter referred to as the wiring member) and screw, bolt is formed, supply socket commonly used at present, generally all can not be applicable to two utmost points or two kinds of plugs of three utmost points simultaneously, and the so-called multipurpose socket of selling on the market, almost mostly is to be combined by a plurality of two utmost points and three pole sockets, along with external electric equipment products constantly enter domestic, the plug specification of running in daily life and the work is more and more, particularly microcomputer is popularized, therefore, society more and more needs a kind of simple and practical adaptable multipurpose socket.Disclosed three hole multipurpose sockets, come with some shortcomings mostly, for example publication number is the Universal Socket of CN1079845A, its intermediate plate is to be turned an angle by the central shaft around its bottom to adapt to the needs of various plugs, its conductive jack be used for parallel flat inserted sheet (two flat plugs and a circle are two flat--be that grounding insert-pin is the circle inserted sheet, the conduction inserted sheet is that the plug of flat inserted sheet is two flat hereinafter referred to as a circle) and oblique flat inserted sheet (three flat plugs) the mid point partly basis of point-blank making up on increase be applicable to that two justify or the combination of the circular arc of three round plugs, its mid point equates with the distance of ground connection intermediate plate, the circular arc of earth jack is again on the middle part or the top of jack, therefore, determined it can not be applicable to promptly simultaneously that domestic multiple two utmost points and three-terminal polarized plus plug are fit to an external circle two flat plugs again, structure is also complicated.Secondly individual other multipurpose socket, its conductive clip does not have circular arc, and is less to the contact area of circle inserted sheet.Moreover existing supply socket all is to rely on the elastic force of intermediate plate to clamp the inserted sheet of plug merely.Through repeatedly, repeatedly, after using for a long time, intermediate plate very easily produces tired damage, the elastic force of intermediate plate reduces, when inserting once more, can not press from both sides steady inserted sheet well, will loose contact or insert unstable, and elastic force improves with the thickness that increases copper sheet often in manufacturer, but has but increased the consumption of copper material.

The purpose of this utility model provides a kind of supply socket, it has can be applicable to multiple two utmost points at present both at home and abroad commonly used and three-terminal polarized plus plug (as common two flat, three flat, two circles, three circles, a circle two flat plugs) simultaneously, simple and reasonable for structure, save material, prolong useful life, characteristics easy to implement.The utility model adopts following scheme to realize its purpose; (1) only changing the jack of socket cover of common flat three pole sockets and corresponding intermediate plate contact jaw (is the summation of the port of intermediate plate and the part that contacts with inserted sheet, hereinafter referred to as the intermediate plate contact jaw) shape, see accompanying drawing 1, accompanying drawing 2 and accompanying drawing 8, all the other most former devices are constant, see accompanying drawing 3, accompanying drawing 4 and accompanying drawing 5, accompanying drawing 6, requirement to receptacle sockets and intermediate plate is, can allow multiple two utmost points and three-terminal polarized plus plug (flat as common two, three is flat, two circles, three circles, one circle, two flat plugs) can both insert easily, and relatively-stationary separately insertion position is arranged, and (two conductive jacks are in the combination that is used for the circular arc that is applicable to two circles and three round plugs that parallel flat inserted sheet and oblique flat inserted sheet mid point partly do not increase on point-blank the combination foundation, distance of mid point and earth jack is unequal separately for it, the part that is used for parallel flat inserted sheet is about to be leaned on, the circular arc of earth jack is partly in its bottom, mainly be in order to be suitable for the needs of an external circle two flat plugs, to see accompanying drawing 1, accompanying drawing 2).Intermediate plate has enough areas to contact well with each shape inserted sheet, the size of the relative position of each jack and size and intermediate plate is determined the position relation of each intermediate plate with the summation of the necessary full terms partly of the various plugs that satisfy to insert, corresponding with jack, concrete structure is seen accompanying drawing.(2) increase spring to intermediate plate, utilize spring to increase the elastic force of intermediate plate, after increasing spring, intermediate plate can adopt thin copper sheet or good conductive metal sheet (also can not increase spring, but, intermediate plate will have enough thickness), do not influence the result of use of socket at all, but promptly reduced production cost useful life of prolong socket again.(3) profile of socket is freely selected as required, earth jack and ground connection intermediate plate are looked its environment for use differently selects last flat circle and two kinds of shapes of flat down, see accompanying drawing 1, accompanying drawing 2 and accompanying drawing 5, accompanying drawing 6, the utility model can be made into single socket or a plurality of use that combines.

Owing to adopt such scheme, make and the utlity model has that the plug that is suitable for is many, simple and reasonable for structure, economical with materials, useful life prolong, particularly change and lack, be convenient to manufacturer and utilize original equipment and parts, less investment again, characteristics easy to implement.Below with reference to accompanying drawing the utility model is described in further detail:
