Description
Technical field
The present invention relates to a kind of elastic button, refer to especially through elastic arm with and change in size bring two elastic arms or many elastic arms button of the stroke alteration that electrically contacts end.
Background technology
Common button (or claiming button, switch) is by elastomeric element and conductive component be combined into, when pushing elastomeric element, drives conductive component and moves contact and turning circuit.The general distance (stroke) that moves is a fixed numeric values, is the one-stroke button, and the function ratio of turning circuit is more single, does not have multiple variation.Be not suitable for the supporting use of complicated circuit.
Application number is that the specification of 200710145324.4 " key structure of adjustable full line journey " discloses one type of base plate with hook part; Base plate is provided with a bridge plate; Be coated with a keycap on the bridge plate, a bridge plate and a keycap structure of an essay are provided with an expansible and the bridge formation that folds, and building bridge comprises the underframe and the upper frame of mutual pivot joint; And make upper frame one end be placed through movably extending between the hook part and bridge plate on the bridge plate from base plate; Corresponding difference is pushed in the keyboard making of stroke, through changing the position of corresponding bridge formation in hook part and bridge plate, reaches the change that keyboard is pushed stroke.This invention structure is too complicated, the non-organic whole of each parts, and upper frame one end mobile is prone to cause dislocation makes keypress function malfunctioning.
The patent No. is US6, and 303,887 United States Patent (USP) discloses a kind of push-button switch element and push-button switch structure; Two strokes electricity contravention with high-order electric contravention, low level electricity contravention, its press-side just are linked to be integral body does not have one that manifest function cuts apart to push the position, and the change of stroke is that the different elasticity compression by press-side causes; Do not have can Free Transform elastic arm, its elastic deformation amount is less, the change of stroke is less; Be difficult for processing multiple-pass; Multipath more can not be accomplished the positive and negative conducting, and suitable circuit variation is less.
Summary of the invention
Goal of the invention:Overcome the complicated shortcoming of traditional single, the adjustable full line journey of one-stroke push button function press-button structure, a kind of more multiple-pass, more two elastic arms or many elastic arms button of multipath are provided
Technical scheme:The invention provides a kind of pair of elastic arm or many elastic arms button, have high-order press-side, low level press-side, high-order electric contravention, low level electricity contravention, reference edge, long-range elastic arm, short distance elastic arm.Plane with reference edge lower surface (or with circuit board contact-making surface) place is a datum level; The position of high-order press-side is higher than the low level press-side; The position of high-order electric contravention is higher than the position of low level electricity contravention, and the difference in height of long-range elastic arm is greater than the difference in height of short distance elastic arm.One side of high-order press-side connects reference edge through the long-range elastic arm, and another side connects the low level press-side through the short distance elastic arm, and the low level press-side also can connect reference edge through the short distance elastic arm.
High-order press-side can respectively have one, two or several; Low level press-side, high-order electric contravention, low level electricity contravention can respectively have one, two or several, and can have identical or different position height separately; Long-range elastic arm, short distance elastic arm can respectively have one, two or several; The short distance elastic arm can respectively have one, two or several, and can have identical or different height is poor.High-order electric contravention can be connected the below of high-order press-side or the below of low level press-side, and low level electricity contravention also can be connected the below of high-order press-side or the below of low level press-side.
When pushed button down side, active force acted on high-order press-side, shrank through the distortion of long-range elastic arm to cause that high-order press-side and low level press-side move down synchronously; Low level electricity contravention at first touches wiring board and can turning circuit; Continue to push, the long-range elastic arm continues distortion and shrinks, and while short distance elastic arm also begins distortion and shrinks; High-order press-side or low level press-side descend, and high-order then electric contravention touches wiring board also can other circuit of conducting.
Long-range elastic arm and short distance elastic arm are processed by elastomeric material (like rubber, rubber and plastic, metal spring etc., preferred silicon rubber), have better elastic distortion and elastic recovery.
If high-order press-side, low level press-side or both are that elastomeric material (can be identical with two kinds of elastic arms) or non-elastic material are processed; When processing by elastomeric material, push downwards when stressed, shrink except the distortion of long-range elastic arm or short distance elastic arm and cause moving down of high-order press-side or low level press-side, high-order press-side or low level press-side itself also can produce elastic compression.
High-order electric contravention and low level electricity contravention are processed by electric conducting material, like metal, graphite or electrically-conducting paint, have excellent conducting performance.
The upper surface of high-order press-side can connect or be mounted with another wiring board in addition; The upper surface of low level press-side also is connected with reverse electric contravention; During button press; Move closer to upper surface with the low level press-side at same horizontal plane to such an extent as to cause the upper surface of high-order press-side, at this moment, reverse electric contravention can touch another wiring board and this circuit of conducting.
Beneficial effect:Compare with common button, button of the present invention has plural electric contravention, can contact with wiring board to form a plurality of connection circuits; Each electric contravention can have identical or different stroke distances before touching circuit board.This button has the function of multipath, multiple-pass, single or double turning circuit.
Compare with some multiple-pass, multiconductor button, organic the linking together of each parts of button of the present invention can one-shot forming be processed an integral body, is not prone to the situation of each parts dislocation misoperation.
Though structure of the present invention is complicated but profile is small and exquisite, in light weight, is applicable to the supporting use of multiple complicated circuit or multifunctional circuit.And the preparation material is corrosion-resistant, ageing-resistant, durable in use.
