Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Shown in Fig. 3, the utility model embodiment provides a kind of miniature button, comprise base 10, be arranged on the conductive pin 20 of described base 10 inside, and button portion 30, described base 10 is in opening up cavity body, by pedestal 11 with to be arranged on described pedestal 11 4 limit be that step-like enclosing 12 is formed, described base 10 inner chamber corner is equipped with limit conducting strip 21, described base 10 lumen centers position is provided with middle conducting strip 22, described conductive pin 20 is provided with outside described base 10, described conductive pin 20 is at least two, be separately positioned on described pedestal 11 both sides, described conductive pin 20 is divided into the first conductive pin 23 and the second conductive pin 24, wherein said limit conducting strip 21 is electrically connected with described first conductive pin 23 through described base 10, described middle conducting strip 22 is electrically connected with described second conductive pin 24 through described base 10, distortion conducting strip 40 is provided with in described base 10 inner chamber, described distortion conducting strip 40 does not suffer oppression state in upwards heaving state, be out of shape after being subject to downforce and position, intermediate portion is contacted with described middle conducting strip 22, described distortion conducting strip 40 4 jiaos contacts with described limit conducting strip respectively and connects, described distortion conducting strip 40 centre is in heaving shape, the first waterproof membrane 50 is provided with above described distortion conducting strip 40, described distortion conducting strip 40 is encapsulated in the inner chamber of described base 10 by described first waterproof membrane 50, described first waterproof membrane 50 is bonded by adhesive and described enclosing 12 top, described first waterproof membrane 50 upper center portion is provided with described button 60, the second waterproof membrane 70 is laid above described button 60, described button 60 is in the described 1, between second waterproof membrane 70 and by adhesive respectively with the described 1, second waterproof membrane 70 bonds.The miniature button that this use is novel provided directly is welded on equipment or pcb board by described conductive pin 20, the design of base 10 is the action of the described distortion conducting strip 40 of rule and position effectively, and described first waterproof membrane 50 serves sealing distortion conducting strip 40 and described limit, middle conducting strip 21, the effect of 22, waterproof solves from home position, described limit, middle conducting strip 21, 22 are with described base 10 integrated injection molding or are heat fused in described base 10, so base 10 position can reach waterproof effect completely, in addition, use two-layer waterproof membrane 50, 70 not only can strengthen waterproof effect further, and solve the problem that in button 60 use procedure, displacement is slided, if directly button 60 is sitting on described distortion conducting strip 40, then waterproof membrane is covered, so anti-slip tank must be set on described distortion conducting strip and prevent button slippage, so cost can be increased and can't reach the effect really preventing it from sliding, bonded by described adhesive between described first waterproof membrane 50 and the second waterproof membrane 70, there is not slip and depart from further confirming button 60 position, be equivalent to clamp described button 60 with two-layer waterproof membrane and fix its position between described waterproof membrane.
In addition, conducting strip 40 is out of shape normally by requirements set specification in prior art, such as 20g, 50g etc., there will be tired state owing to using rear flow of metal conducting strip 40 for a long time thus be on the verge of fault, and under normal circumstances, higher thicker of pressure specification, the so thicker distortion conducting strip life-span is shorter, so, the utility model embodiment adopts shape changeable conducting strip structure, there are in described base 10 at least two distortion conducting strips 41, 42, be respectively be in bottom contact with described limit conducting strip 21 connect first be out of shape conducting strip 41 and be in described first and be out of shape second above conducting strip 41 and be out of shape conducting strip 42, often the second distortion conducting strip 42 can adopt the material with deformability speciality of other materials, in fact do not require to be necessary for conduction demand as title so-called " conducting strip " yet, the second distortion conducting strip 42 is only needed to play the effect of distortion, the useful life of switch key entirety can be extended like this, in order to reduce accessory cost further, being out of shape conducting strip 42 area design by described second is the specification being less than described first distortion conducting strip 41, described second distortion conducting strip 42 only has center and heaves part, described second distortion conducting strip 42 is buckled in described first distortion conducting strip 41 center and heaves position and utilize adhesive or electric welding mode and described first to be out of shape conducting strip 41 and be connected, when there is deformation in described second distortion conducting strip 42 under the pressing of described button 60, be out of shape conducting strip 41 and be added with first and can reach pressure specification, such design then decreases the loss in material, if the cost at edge 40 percent can be reduced when significantly switching surface designs.
Described first distortion conducting strip 41 length direction has the radian upwards arched upward; its elasticity of further increase; and have extension space to slide on limit conducting strip 21 when compressive deformation, the design of arch radian can protect button 60 to be unlikely to damage the elasticity of described distortion conducting strip 40 when exertin presses down completely.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
