Description
Technical field
The present invention relates to a kind of elastic button, espespecially pass through two elastic arm of the stroke alteration of elastic arm and its change in size band electrical contact end or many elastic arm buttons.
Background technology
Common button (or claiming button, switch) is combined into by elastomeric element and conductive component, during by elastic member, drives conductive component moving contact and turning circuit.The distance (stroke) of general movement is fixing numerical value, and be one-stroke button, the function ratio of turning circuit is more single, does not have multiple change.Be not suitable for complicated circuit to support the use.
Application number is that the specification of " key structure of adjusting stroke " of 200710145324.4 discloses the base plate that a class has hook part, base plate is provided with a bridge plate, bridge plate is coated with a keycap, bridge plate and a keycap structure of an essay are provided with an expansible and the bridge formation folded, build bridge and comprise underframe and the upper frame of mutual pivot joint, and make upper frame one end be placed through movably extending between hook part on bridge plate and bridge plate from base plate, in the keyboard making of corresponding different pressing stroke, by changing the position of the corresponding bridge formation in hook part and bridge plate, reach the change of keyboard pressing stroke.This invention structure is too complicated, and the non-organic whole of all parts, the movement of upper frame one end easily causes dislocation and makes keypress function malfunctioning.
The patent No. is US6,303,887 U.S. patents disclose a kind of push-button switch element and push-button switch structure, there are two stroke electricity contraventions of high-order electric contravention, low level electricity contravention, its press-side is just linked to be the pressing position that entirety does not have manifest function to split, the change of stroke is caused by the different elastic compression of press-side, not having can the elastic arm of Free Transform, its elastic deformation amount is less, the change of stroke is less, not easily makes multiple-pass, multipath, more can not accomplish positive and negative conducting, applicable circuit variation is less.
Summary of the invention
goal of the invention:overcome that traditional one-stroke push button function is single, the shortcoming of adjusting stroke press-button structure complexity, a kind of two elastic arm of more multiple-pass, more multipath or many elastic arm buttons are provided
technical scheme:the invention provides a kind of two elastic arms or many elastic arm buttons, there is high-order press-side, low level press-side, high-order electric contravention, low level electricity contravention, reference edge, long-range elasticity arm, short distance elastic arm.With the plane at reference edge lower surface (or with circuit board contacts face) place for datum level, the position of high-order press-side is higher than 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 elasticity arm is greater than the difference in height of short distance elastic arm.High-order press-side while connect reference edge by long-range elasticity arm, another side connects low level press-side by short distance elastic arm, and low level press-side also can connect reference edge by short distance elastic arm.
High-order press-side respectively can have one, two or several; Low level press-side, high-order electric contravention, low level electricity contravention respectively can have one, two or several, and can have identical or different position height separately; Long-range elasticity arm, short distance elastic arm respectively can have one, two or several; Short distance elastic arm respectively can have one, two or several, and can have identical or different differences in height.High-order electric contravention can be connected to the below of high-order press-side or the below of low level press-side, and low level electricity contravention also can be connected to the below of high-order press-side or the below of low level press-side.
When button down side presses, active force acts on high-order press-side, high-order press-side and low level press-side is caused synchronously to move down by the deformation retract of long-range elasticity arm, first low level electricity contravention touches wiring board and can turning circuit, continue pressing, long-range elasticity arm continues deformation retract, and short distance elastic arm also starts deformation retract simultaneously, high-order press-side or low level press-side decline, and then high-order electric contravention touches wiring board and can other circuit of conducting.
Long-range elasticity arm and short distance elastic arm are made up of elastomeric material (as rubber, rubber and plastic, metal spring etc., preferred silicon rubber), have good strain and elastic recovery.
If high-order press-side, low level press-side or both be that elastomeric material (can be identical with two kinds of elastic arms) or non-elastic material are made; When being made up of elastomeric material, when downwards pressing is stressed, the deformation retract except long-range elasticity arm or short distance elastic arm causes moving down of high-order press-side or low level press-side, and 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 made up of electric conducting material, as metal, graphite or electrically-conducting paint, have good electric conductivity.
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 is also connected with reverse electric contravention, during button press, cause the upper surface of high-order press-side to move closer to such an extent as to and the upper surface of low level press-side at same horizontal plane, now, reverse electric contravention can touch another wiring board and this circuit of conducting.
beneficial effect:compared with common button, button of the present invention has plural electric contravention, can contact form multiple connection circuit with wiring board; Each electric contravention, before touching circuit board, can have identical or different stroke distances.This button has the function of multipath, multiple-pass, single or double turning circuit.
Compared with some multiple-pass, multiconductor button, button all parts of the present invention is organic to link together, and one-shot forming can make an entirety, not easily occurs the situation of all parts dislocation misoperation.
Although the complicated but low-profile of structure of the present invention, lightweight, be applicable to Various Complex circuit or multifunctional circuit supports the use.And prepare material corrosion resistance, ageing-resistant, durable in use.
