Description

一种按键开关的侧向导通组件 技术领域
本实用新型涉及按键开关领域，尤其涉及一种按键开关的侧向导通组件。
背景技术
按键开关主要是指轻触式按键开关，也称之为轻触开关。按键开关是一种电子开关，属于电子元器件类，使用时以满足操作力的条件向开关操作方向施压开关功能闭合接通，当撤销压力时开关即断开，其内部结构是靠金属弹片受力变化来实现通断的，被广泛应用在蓝牙耳机、收银机、部分工业设备等地方。
目前市面上常见的按键开关主要是包括基座、上盖、静片、动片和按钮件等零部件。通过上盖和基座形成一容置腔，动片和静片设置在该容置腔内，并且动片和静片上的弹性部位向下延伸直至接触到外部的电路板，实现与外部电路板的电连接。由于动片和静片的弹性部位需要要往下延伸的空间，所以普遍的按键开关为了预留这个空间，其整体都做得较高，不适用于一些超薄型的键盘和某些工业设备中。而且这种常见的按键开关基本都是直接设置在所需设备上，如果出现问题，很难进行拆卸和替换。

对于所述动片支臂231的具体结构，如图1至图6所示，所述动片支臂231上还设置有一向下弯折且向上延伸的一动片第二弯折部2312，所述动片第一弯折部2311设置于所述动片第二弯折部2312上。优选的，所述动片第二弯折部2312向下呈U形弯折，且弯折的高度较低。通过设置向下弯折且向上延伸的动片第二弯折部2312配合设置于动片第二弯折部2312上且向侧方延伸的动片第一弯折部2311，使动片支臂231更好地往侧方延伸，从而实现动片23在侧方与PCB板1的导通，并且减少了动片23的整体高度，实现动片23的轻薄化。

为了更好地让动片推动部234接收到下文所述活动块26的推动作用力，如图1至图7所示，所述动片推动部234向静片接触部243方向弯折。通过把动片推动部234向静片接触部243方向弯折，该弯折处使动片推动部234更好地与下文所述活动块26接触，提高了按键开关上的推动部件与下文所述活动块26的配合度，提升了动片推动部234的推动精准度，进一步提高了本组件的工作效率。
对于所述静片24的具体结构，如图1至图6所示，所述静片24上还设置有一体成型的一静片固定部242、以及连接于静片固定部242一端且与动片接触部233相匹配的一静片接触部243。所述静片24通过静片固定部242固定于壳体21上，连接于静片固定部242的静片接触部243同时被固定于壳 体21上，由此保证静片接触部243在使用过程中不易移动或者脱落，减少了静片接触部243与动片接触部233的误触，保证了本组件的正常导通和断开。
为了更好地让动片接触部233和静片接触部243进行导通，如图4至图6所示，所述静片24接触部243向动片接触部233方向弯折，从而减少静片接触部243和动片接触部233之间的距离，使静片接触部243和动片接触部233在需要导通的情况下可以更快的进行导通，进一步提高了本组件的导通速度和导通效率。

优选的，所述动片接触凸块2331为横向设置的半圆柱形形状，如图6所示，所述静片接触凸块2431为纵向设置的半圆柱形形状。横向和纵向的设计扩大了静片接触凸块2431和动片接触凸块2331的可接触范围，提高了动片23与静片24的接触效率，从而进一步提升了本组件的接触配合度，提高了本组件的工作效率。

对于所述动片23和静片24穿出底座211与PCB板1电连接的具体结构，如图1至图4所示，在所述底座211的同一侧边外壁上开设有与动片支臂231相匹配的动片伸出口213、以及与静片支臂241相匹配的静片伸出口214，所述动片第一弯折部2311穿出该动片伸出口213与PCB板1电连接，所述静片第一弯折部2411穿出该静片伸出口214与PCB板1电连接。通过在底座211 的同一侧边外壁上开设动片伸出口213，方便所述动片第一弯折部2311从该动片伸出口213穿出与PCB板1电连接，提高了动片与PCB接触的速度，进一步提高了动片导通的效率。通过在底座211的同一侧边外壁上开设静片伸出口214，方便所述静片第一弯折部2411从该静片伸出口214穿出与PCB板1电连接，提高了静片与PCB接触的速度，进一步提高了静片导通的效率。
对于所述PCB板1的具体结构，如图1至图3所示，所述PCB板1上设置有与所述壳体21相匹配的连接放置口11，所述连接放置口11上设置有与所述动片第一弯折部2311相匹配的一动片连接口12，以及与所述静片第一弯折部2411相匹配的一静片连接口13。所述动片第一弯折部2311的弯折处与动片连接口12相接触，实现动片23与PCB板1的导通连接。所述静片第一弯折部2411的弯折处与静片连接口13相接触，实现静片24与PCB板1的导通连接。通过在PCB板1上设置有与所述壳体21相匹配的连接放置口11，从而方便侧向导通结构2卡扣于PCB板1上并与PCB板1电连接，且结构简单，操作便捷，提高了侧向导通结构2从PCB板1上拆卸更换的速度，进一步提高了本组件的实用性。通过在所述连接放置口11上设置有与所述动片第一弯折部2311相匹配的一动片连接口12，以及与所述静片第一弯折部2411相匹配的一静片连接口13，从而提高动片23和静片24与PCB板1电连接的配合度，进而提升了侧向导通结构与PCB板1的导通效率。
对于所述导芯22作用于动片推动部234的具体方式，如图4至图7所示，所述安装部2112上且位于导芯22和动片推动部234之间开设有一活动槽215，该活动槽215上设置有一活动块26，所述活动块26抵压于所述动片推动部234上；所述导芯22上且位于朝向活动块26的方向形成有一推动凸块221。优选的，所述推动凸块221朝向活动块26的一侧为向下45度的倾斜状。
如图7所示，当按下导芯22时，导芯22上的推动凸块221同时往下移动，所述推动凸块221上的倾斜面与活动块26分离，由于动片23自身的弹力恢复作用力，使动片接触部233回弹至于静片接触部243接触的状态，并且动片推动部234带动活动块26同步弹动，使活动块26往导芯22方向横向左右移动，使活动块26处于与导芯22上的推动凸块221分离且位于推动凸 块221上方的状态。当使用人员没有按下导芯22时，由于所述弹性件25的弹性恢复力，使设置于弹性件25上方的导芯22被带动往上移动复位，此时导芯22上的推动凸块221同步向上移动并且抵压于活动块26上，使活动块26往动片推动部234方向移动。此时动片推动部234在活动块26的推动下，带动连接于其上的动片接触部233与静片接触部243分离，从而实现动片23与静片24之间的不导通目的。通过设置活动块26与导芯22上的推动凸块221相匹配使用，提高了导芯22与动片之间的配合精准度，进一步提高了本组件的反应灵敏度。
为了防止动片23与静片24进水被腐蚀，如图3、以及图5所示，所述底座211上还设置有一防水盖27，该防水盖27盖合于所述安装部2112上。通过设置该防水盖27，使防水盖27与安装部2112形成一防水空间，且所述动片23与静片24设置于所述防水空间内，从而有效保护了动片23与静片24不容易进水被腐蚀，提高了本组件的使用寿命。
