Abstract

A kind of electrical socket, by socket shell fragment 1,12, base plate 2, termination 3 and cover 4 and constitute.It is characterized in that the installation between socket shell fragment and the base maybe can being used with different plugs, bring convenience to the user around axle 5 rotations or fixing at an angle.

Description

Universal power socket

The invention discloses a kind of 220V(of being used for or 110V) supply socket of civil power.

Along with the continuous development of household electrical appliance, used plug kind increases, but the existing power supply socket especially is contained in the socket on the indoor wall, can only adapt to one or two kind of plug, and this often makes troubles to use.Can only just plug plug of all sizes, that shape is different with a socket? purpose of the present invention will solve this and appear impossible problem.

For this reason, must design a kind of socket shell fragment that can well contact with the insert-connecting plate (or post) of various plugs, a kind of energy

Jack that various plugs insert smoothly and respective base, wiring mechanism below in conjunction with accompanying drawing, elaborate to the present invention.

Accompanying drawing 1 is the schematic perspective view of a kind of plug of the present invention.Socket shell fragment (1) among the figure (two in live wire and center line arranged, in following stating, all claim (1)), with connecting between the base plate (2) be one of key of the present invention.Here can adopt two kinds of connecting modes: shell fragment (1) can rotate in the certain limit on base plate around axle (5); Or with (

± 20) Du angle and base plate fix (referring to Fig. 2: shell fragment shape and fixed angle, among the figure The angle be flat three outlet ground shell fragments commonly used with shell fragment (1) between angle, generally be about 40 °), here, " rotations " is an individual way ingeniously, it solved satisfactoryly angled (promptly

The angle) two kinds of flat pins are the difficult problem of same socket shell fragment altogether.Does but thing followed problem is: how the shell fragment of this rotation keep good being electrically connected with external connection (and great majority are sub-thread rigid lines)? two ways are also arranged here, one as shown in Fig. 1 is upper left, shell fragment (1) is fixing with rotating shaft (5), between (5) and outer terminal (or screw) (13), be connected with the multiply thin and soft wire, another is as figure, 1 lower-left is drawn, between (5) and (13), establish and rotate contact mechanism (9), form by rotating shaft (5), contact chip (10) and spring (or spring leaf) (11).(10) keep well contacting under (11) effect with (1), the end in addition of (10) promptly is (13).For the restriction shell fragment slewing area, on base plate (2), be provided with stop portion (7), its restriction moving range be (

± 20) degree, the best is Degree, its shape and size be by the bottom of shell fragment (1) and limited field decision, and Fig. 1 shell fragment bottom of having drawn the bottom right is square, and limited field is

The spacing line of degree as solid line among the figure, selects solid line but need only one or two by this rule in actual production, not necessarily shine the shape among the figure entirely.

For making shell fragment all can keep excellent contact with various plugs (garden, flat, have big displacement), shell fragment is made with whippy good electric conducting material (as phosphorus bronze sheet or other shell fragment), shell fragment (1) is made generally in " recessed " shape, its peak apart from the distance of base plate than the high 0-5mm of common socket shell fragment.Under the fixing situation of shell fragment and base plate.It and plug contact position can be made into such shape (shown in Fig. 2 left side), and on the vertical plane S of contact position, shell fragment is made of two straight lines (or intimate straight line) and middle garden arc three parts, wherein the angle of cut of two straight lines be ((180 °-

) ± ) the best be (180 °-

), the radius of garden arc is that corresponding plug radius ± 5mm(the best is that the two equates, if the plug of two or more different radiis, with maximum equate be advisable).The shape of grounding elastic part (12), size are by required ground pin decision, it generally constitutes by connecing flat plug part (B) and connecing 1-2 garden plug portion (E), wherein (B) adopts general shell fragment (but wanting narrow 0-4mm), (E) can be cylindricality, monolithic, biplate, or and B(B) fuses Fig. 3 its several schematic perspective views that drawn.

On lid (4), open three extremely wide jacks of adaptability, and require all plugs easily of various plugs, it is another key of the present invention, the inventor is by the analysis to the various plugs in the existing 10 peace left and right sides, found out rule wherein, the upper right and Fig. 4 of Fig. 1 various possible jacks that drawn: 1. two flat add three flat; II. I adds two gardens; III.II adds San Xiaoyuan; IV. II adds San Dayuan; Y. II add San Xiaoyuan add three big gardens etc. several, in a word, cover the relative position and the shape of three jacks, size, be by various plugs must use the summation of part or partly constitute by using more than two or two, in actual production, can suitably increase, so that process and attractive in appearance.Above-mentioned Y wide adaptability, but see seldom that in view of little three garden plugs IV promptly is the Universal Socket (lid) of function admirable, and two flat now, three flat plugs are most widely used, 1 or II be two kinds of simplification models that are worthy to be popularized.

Socket of the present invention not only can cooperate with existing various home electric appliance plugs easily, and the electric property that cooperates with each plug can meet or exceed common socket, its processing and cost and general socket are similar, and these all are that advantage has been created in its penetration and promotion.

Though thing of the present invention is little, meaning is not little, because almost everyone runs into the worry that appliance plug can not cooperate with existing socket, " Universal Socket " brings convenience to people is self-evident.Because one-object-many-purposes, you needn't go for or buy another set of transition plug-in connection, not only reduce expenses, and also are that country saves electrotechnical apparatus, its economic benefit and obvious social benefit.
