Background technology
At present, the button touch-switch is used very extensively on all kinds of remote controllers and electronic instrument, the big key touch-switch that prior remote controller is used is generally multi-direction switch, the position up and down of the center and peripheral of this multi-direction switch is provided with a plurality of moving contacts altogether, press the relevant position of big key touch-switch, the closed corresponding function of realizing remote controller of the corresponding moving contact and the fixed contact of circuit board.But the position of pushing the big key touch-switch is unpunctual, and misoperation takes place easily.Existing unidirectional button touch-switch is generally little key switch, and it is not too convenient to operate.
The utility model content
The purpose of this utility model is to provide a kind of unidirectional big key touch-switch, all can connect circuit during the optional position of pressing keys, solves the problem of existing button touch-switch inconvenient operation.
The purpose of this utility model is achieved by the following technical programs:
A kind of big key touch-switch, comprise button, loam cake, wiring board, lower cover, metal clips, adjustment screw, described button edge sinks into a circle chimb, the top edge in-flanges of loam cake is withheld the chimb of button, the button upside passes from loam cake, described wiring board is arranged on the button downside, described metal clips is fixed on the wiring board downside, wiring board and metal clips are contained in described lower cover bottom, described loam cake is fixedlyed connected by several securing members with the lower cover edge, and described adjustment screw is resisted against the metal clips downside after passing lower cover.
The purpose of this utility model can also further realize by following technical measures:
Aforesaid big key touch-switch covers under wherein said and is provided with several elastic bars, and described several elastic bars are that the center becomes radiation to distribute with the adjustment screw.
Aforesaid big key touch-switch, wherein said several elastic bar becomes cantilever-shaped and is separately positioned in the lower cover window, described elastic bar outer end camber in the lower cover window is outwardly-bent and extend the formation salient point that turns back, described wiring board floats and is supported on several salient points, leaves gap b between described wiring board downside and the elastic bar root.
Compared with prior art, the beneficial effects of the utility model are:
The utility model compact conformation, the area of button is big, and the optional position of pressing keys is the unidirectional connection circuit of energy all, good hand touch, highly sensitive, easy to use.Lower cover elastic bar of the present utility model has good unsteady supporting role to wiring board, and after the pressing keys, elastic bar can make wiring board automatically reset.Metal clips of the present utility model adopts the depression claw type structure of shell fragment central plate and several feets, and elastic effect is good, as long as small pressing force is arranged, just can make the unidirectional connection related circuit of metal clips; External force removes, and related circuit disconnects, and metal clips restores to the original state.The turn adjustment screw, the size that can regulate space a between shell fragment central plate and the wiring board, thereby the elastic reset power of regulating metal clips, when guaranteeing the optional position of pressing keys, metal clips all can unidirectional connection related circuit.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 4, the utility model comprises button 1, loam cake 2, wiring board 3, lower cover 4, metal clips 5, adjustment screw 5, the button 1 of present embodiment by 4 arcs form approximate rectangular, also can be circle, ellipse or other shapes.Button 1 edge sinks into a circle chimb 11, and loam cake 2 is the shaped as frame structure, and its shape and button 1 outer rim shape are coincide, and the top edge in-flanges 21 of loam cake 2 is withheld button 1, prevents that button 1 from coming off in loam cake 2, and button 1 upside passes from loam cake 2.Wiring board 3 is arranged on button 1 downside, metal clips 5 is fixed on wiring board 3 downsides, wiring board 3 and metal clips 5 are contained in lower cover 4 bottoms, and loam cake 2 is fixedlyed connected by 4 rivets 7 with lower cover 4 edges, and adjustment screw 6 is resisted against metal clips 5 downsides after passing the boss of lower cover 4 central authorities.
It is 4 elastic bars 41 that the center becomes radiation to distribute that lower cover 4 is provided with adjustment screw 6,41 one-tenth cantilever-shaped being separately positioned in the lower cover window 42 of described 4 elastic bars, elastic bar 41 outer ends cambers in the lower cover window 42 are outwardly-bent and extend to turn back and form salient point 411, wiring board 3 floats and is supported on 4 salient points 411, leaves gap b between wiring board 3 downsides and elastic bar 41 roots.Pushed button 1 o'clock, the downward active force that wiring board 3 is subjected to button 1 moves down, and the active force that 4 salient points 411 are subjected to wiring board 3 moves down, and elastic bar 41 is subjected to being out of shape from the pressure of wiring board 3, and gap b diminishes.When external force was removed, elastic bar 41 restored immediately, and the elastic force of elastic bar 41 promotes to move on wiring board 3, the button 1, and button 1 one circle chimbs 11 are subjected to loam cake in-flanges 21 in last process of moving restriction is returned to initial condition.Turn adjustment screw 6 is regulated space a between shell fragment central plate 51 and the wiring board 3, and when the optional position of pressing keys 1, metal clips 5 all can the corresponding circuit of unidirectional connections.
As shown in Figure 5, when the right side edge off-centre of button 1 is pushed the utility model, button 1 right side promotes wiring board 3 right sides and tilts to move down, right side elastic bar 41 is subjected to the crimp of wiring board 3, gap b reduces, the space a that is positioned at metal clips 5 depressions of wiring board 3 center downsides also reduces the moving contact in the metal clips 5 and the fixed contact closure of wiring board 3, thereby the corresponding circuit of unidirectional connection.In like manner,, the space a of metal clips 5 depressions is reduced in the optional position pressing keys 1 of left side, upside, lower edge or the button 1 of button 1, thus the corresponding circuit of unidirectional connection.
Further expand as of the present utility model, can set up special circuit board, just can make the utility model obtain mouse function at button 1.As remote controller, during the diverse location point of pressing keys 1, can be equipped with corresponding demonstration in the display screen corresponding positions as display screen.
In addition to the implementation, the utility model can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
