Description

一种高寿命微动开关 技术领域
本发明涉及一种微动开关，尤其涉及一种高寿命微动开关。
背景技术
微动开关是一种常用的开关机构，其是一种具有微小接点间隔和快动机构，用规定的行程和规定的力进行开关动作的接点机构，被广泛应用于工业、电子、机械、治金、电力等领域中。
现有微动开关的工作原理是：外机械力通过传动元件(按销、按钮、杠杆、滚轮等)将力作用于动作簧片上，当动作簧片位移到临界点时产生瞬时动作，使动作簧片末端的动触点与静触点快速接通或断开。
现有的这种微动开关，通常采用将动触点设置于动作簧片上的方式，在动作簧片被按压的前后，动触点分别与位于动作簧片上方或下方的静触点相接触，实现导通或断开的功能。采用这种纵向正面触碰的方式，由于微动开关经常被施加较大的按压力，相应的动作簧片具有较大的弹性恢复力，因此，导致动触点对静触点施加了过大的正面作用力，两者之间均为正面受力，且受力过大，两者接触面易产生磨损，寿命明显减少，一般寿命仅有1000万次。
发明内容
针对上述不足，本发明的目的在于提供一种高寿命微动开关，通过控制双脚动片的弹开与合拢，实现双脚动片上的触点与引脚之间为侧面接触与分离，从而实现微动开关的导通与断开功能，触点与引脚之间仅相互摩擦，两者之间的受力方向变成侧面受力，减少相互磨损的可能性，大幅提高寿命，且寿命提高到8000万次。

本发明实施例提供的微动开关，适用于工业、电子、机械、治金、电力等领域，特别适用于各种电器与各种汽车中控台上。
本发明实施例的工作原理为：
微动开关处于自然状态时，活动片5的左推动部52位于上让位块625正外侧边，即处于上让位部621位置处，则左推动部52未对双脚动片6的左动片62施加作用力，因此，左动片62上的左触点622与左引脚7接触导通；同时，活动片5的右推动部53位于双脚动片6的右动片63侧边，并向内侧推动右动片63，使右动片63向内侧合拢，从而右动片63上的右触点632与右引脚8分离断开。
当向下按压导芯3时，导芯3对拉簧4施加向下的作用力，同时推动活动片5向下移动，带动左推动部52下移并离开上让位部621位置处，并移动至左动片62侧边且位于上让位块625下方，则左推动部52向内侧推动左动 片62，使左动片62向内侧合拢，从而左动片62上的左触点622与左引脚7分离断开；于此同时，活动片5向下移动带动右推动部53下移，右推动部53进入下让位部631位置处，即位于下让位块635正外侧边，则右推动部53未对双脚动片6的右动片63施加作用力，因此，右动片63向外侧弹开恢复原状，右动片63上的右触点632与右引脚8接触导通。当松开对导芯3的按压时，微动开关恢复至自然状态。
本发明的重点主要在于，
(1)通过增加具有特殊结构设计的双脚动片与活动片，并将导通引脚分开设置于双脚动片两侧边，并通过活动片来控制双脚动片的弹开与合拢，实现双脚动片上的触点与引脚之间为侧面接触与分离，从而实现微动开关的导通与断开功能，触点与引脚之间仅相互摩擦，两者之间的受力方向变成侧面受力，减少相互磨损的可能性，大幅提高寿命，且寿命提高到8000万次；
(2)通过对活动片的结构进行优化改进，采用向正下方弯折形成的活动片让位部，为拉簧的活动提供让位空间，在微动开关尺寸大小一定的情况下，为双脚动片的安装设置提供侧边空间，结构设计更合理紧凑；
(3)采用拉簧结构，增加了活动片的力臂长度，拉簧的可调空间更大，实现多种不同的手感和声音。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故采用与本发明上述实施例相同或近似的技术特征，而得到的其他结构，均在本发明的保护范围之内。
