Description

Universal power source 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, particularly a large amount of listings of import electrical equipment since the reform and opening-up, the kind of used attaching plug increases, but existing power supply socket, especially be contained in the socket on the indoor wall, can only adapt to one or two kind of plug, this often makes troubles to use.Can only just adapt to of all sizes, different plug with a socket?

The inventor had once retrieved a large amount of interrelated datas, find that similarly application has a plurality of, but its tangible weak point is arranged respectively, as domestic early stage patent 85202788, be the three garden sockets of cancelling already based on China, inapplicable new national standard, and plug conversion will regulate by a plate, uses trouble; After this, patent application 87212161,88214364,6 etc. improves it, but structure is still complicated, and is only applicable to domestic several plug.For on the import electrical equipment, as an international garden two flat, big two gardens etc., institute's example of investigating into a case does not almost all consider that the general character of socket is limited in scope.

Purpose of the present invention just provides and a kind ofly can overcome above-mentioned shortcoming, adapts to common various plugs and simple in structure both at home and abroad, and the novel power supply socket of function admirable is to satisfy users' needs.

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 various the plugs jack of insertion and respective base, wiring mechanism smoothly of allowing below in conjunction with accompanying drawing, elaborates 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 kinds of phase line L and center line N are arranged, all claim (1) in the following description), 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 ((α)/2 ± 30) degree angle and base plate fix (referring to Fig. 2-1, the α angle is the angle between flat three outlet ground shell fragments commonly used and shell fragment (1) among the figure, GB is 30 °), here, " rotation " solved the altogether difficult problem of same socket shell fragment of two kinds of angled flat pins.But thing followed problem is; How does 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 shown in Fig. 1-a, 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 drawn as Fig. 1-b, between (5) and (13), establish and rotate contact mechanism (9), by rotating shaft (5), contact chip (10) and spring (or spring leaf) (11) are formed, (10) keep well contacting under (11) effect with (1), the end in addition of (10) promptly is (13).Slewing area for the restriction shell fragment, on base plate (2), be provided with stop portion (7), its restriction moving range is (α ± 30) degree, the best is the α degree, and 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, limited field is the spacing line of α degree, as solid line among the figure, select solid line but in actual production, need only one or two by this rule, not necessarily shine the shape among the figure entirely.

Above-mentioned " rotation " mode is simplified the complex structure that still seems in any case, and the inventor has adopted the fixing method of shell fragment and base plate in the advanced development process, and it is completely successful to have obtained the garden.The key here also is that difficult point is the shape of position, angle, the especially shell fragment fixed, and this will see that concrete condition selects for use flexibly.As corresponding to the jack shown in Fig. 4-a three kinds of plugs such as (it be applicable to) GB are two flat, three flat and international gardens two are flat, the feature of shell fragment shape should satisfy (referring to Fig. 2-a): on the cross section (S) of it and plug contact position, sheet in the shell fragment section (21) (or outer plate (22)) is made of two straightways (or intimate straightway), the angle of cut of two lines is ((180-α) ± α), the best be (180 °-α), the fixed angle of it and base plate is ((α)/2 ± 30 °), and the best is (α)/2.This and following design is very ingenious, make shell fragment keep well contacting with angled plug, and structure is very simple.For being fit to the plug garden and big displacement, shell fragment can be made into the widest shape of following versatility, drawn as Fig. 2-b: on cross section (S), sheet is by the line segment parallel with grounding elastic part (23) in the shell fragment, form (also can increase and three line segment (27) of (26) angle of cut for (90 ° ± 30 °)) with (23) angle of cut for the line segment (26) of ((180 °-α) ± 15 °), the shell fragment outer plate is made up of straightway (24) arc (25).

Shell fragment is made of whippy good electric conducting material (as phosphorus bronze sheet) punching press, be made generally in "

" shape, its peak apart from the distance of base plate than the high 0～3mm of common socket shell fragment.Shape, size by ground shell fragment (12) are determined by required ground pin, it generally constitutes by connecing flat plug part (B) and connecing garden plug portion (E), wherein (B) adopts general shell fragment (but wanting narrow 0-6mm), (E) can be cylindricality, monolithic, biplate, or and B(B) toroidal that fuses, Fig. 3 its four kinds of schematic perspective views that drawn.

On lid (4), open three extremely wide jacks of adaptability, both required all can dial easily, insert to various plugs, meet GB and pertinent regulations again, it is another difficult point of the present invention, the inventor has found out rule wherein by the analysis to the various plugs in the existing domestic and international 10 peace left and right sides, Fig. 4 several possible jacks that drawn, they are applicable to following plug respectively: I. as described above, two flatly add three flat to add a garden two flat; II. two gardens are strengthened in the two flat three flat young waiter in a wineshop or an inn of the adding gardens that add; III .(II) strengthens three gardens; IV .(III) it is flat to add a garden two, and they cooperate with corresponding shell fragment and base plate etc., can constitute the Universal Socket of different model.Concrete shape facility to these jacks is not described here one by one, only (Fig. 4-d) is an example: phase line (or center line) jack can be made of four parts with the widest a kind of of adaptability, the rectangle slotted eye of opening by GB (10 peaces, 250 volt of two pole socket) (G) is arranged at the end of line jack (14) closely, end has the rectangle tilted slotted hole of opening by GB (10 peaces, 250 volt of three pole socket) (H) in addition, set up in the middle of two grooves and isolate salient angle (T), there is hole, garden (F) outside, and the size and location in this hole, garden are determined by Da Sanyuan and big two garden plugs.Ground wire jack is made of two parts: near phase line (or center line) end the rectangle slotted eye of opening by GB (three pole sockets) (K) is being arranged, end has hole, garden (O) in addition, its size and big three gardens, position are determined, 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 institute must use part to constitute more than two or two, can suitably increase in actual production, so that processing and attractive in appearance.

Compared with prior art, the present invention has series of advantages, and is with the obvious advantage.Its structure simple, processing is easily, cost cheap, very nearly the same with common socket, this is that all blanket sockets are beyond one's reach so far, and wide, the getting well of performance of its versatility makes us being difficult to believe easily.This only has the slight socket of three eyes, unexpectedly can plug domestic and international various plug as the magician: two flat (GBs), young waiter in a wineshop or an inn garden (using always), big two gardens (English mark), oblique three flat (GBs), straight three is flat, one garden two directly flat (English mark), one garden two is tiltedly flat, two gardens one are flat, big three gardens (using always) or the like, estimable is: it and various plug all can be good fit, every electric property, as outward appearance, dial slotting power, withstand voltage, voltage drop, temperature rise, mechanical strength or the like all can reach very ends above domestic, international related standards, and meet safety, the pertinent regulations of aspect, market, all these has created advantage for its penetration and promotion.

Though thing of the present invention is little, meaning is not little, because almost everyone can run 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, and " universal power socket " will become the renewal product in the socket world.
