Description

一种插板式超薄型按键开关 技术领域
本实用新型涉及一种按键开关，尤其涉及一种插板式超薄型按键开关。
背景技术
按键开关，为一种广泛应用于键盘上的开关。这种开关的主要结构包括有基座、上盖、静触片、动触片和导芯，该上盖和基座围合形成容置腔，该静触片、动触片和导芯设置于该容置腔中，且该导芯的一端露出容置腔外，通过按压操控导芯，使得导芯上下活动，进而通过导芯作用于动触片上，使得动触片与静触片接触连接或脱离分开，从而实现按键开关的导通与断开功能。
上述现有的按键开关结构，虽可提供给使用者断开或导通静触片与动触片之间的连接的功效。但是在实际使用时却发现其自身结构和使用性能上仍存在有诸多不足，造成现有的按键开关在实际应用上，未能达到最佳的使用效果和工作效能。
现有大多数按键开关的静触片与动触片的焊脚通常采用贴板方式贴在PCB板上表面上，以实现与PCB板的连接。而由于按键开关在焊接过程中，其焊脚与PCB板连接处会产生大量热量，采用这种贴板式连接方式，不但对焊脚及按键开关其他结构制备材料的耐高温性能提出了更高的要求，提高了材料成本；而且由于产生的热量与按键开关整体结构位于PCB板同一侧，热量会使按键开关上的塑胶件熔化，导致功能不良。
同时，按键开关的按压手感及产品厚度一直都不能满足用户的需求，按压手感比较好的按键开关，产品整体厚度必然很厚，而产品厚度比较薄的产品，其按压手感又受到很大的限制。传统的提高按压手感的方法是，直接加高同一导芯的高度，以获得高按压行程，从而提高按压手感，然而，采用直接加高导芯的方式，必然会加高按键开关(基座)的整体高度，因此，按压 手感与产品厚度难以同时满足要求。
实用新型内容
针对上述不足，本实用新型的目的在于提供一种插板式超薄型按键开关，采用插板式焊接结构，不但大幅提高了散热效果，对按键开关性能无影响，而且对制备材料性能要求降低，无需要求为耐高温材料，普通材料即可，从而降低了材料成本，组装费用减少，组装更方便快捷，组装易实现自动化。

作为本实用新型的进一步改进，在所述基座上且位于外导芯外围扣合有一盖子，在该盖子上开设有供按压凸块穿出的一大穿孔。
作为本实用新型的进一步改进，在所述内导芯的按压凸起下端面向上凹设有一内导芯导槽，在该内导芯导槽中部向下凸设有一导轴；在所述基座上且位于按压凸起正下方向上凸设有一导柱，在该导柱中心轴方向上向下凹设供导轴插入的一基座导槽；所述导轴与导柱外套设有一复位弹簧，且该复位弹簧上端嵌入于内导芯导槽中，下端围设于导柱外围。
作为本实用新型的进一步改进，在所述基座上且位于外导芯外侧边设置有一扭簧；在该外导芯的外侧边设置有与扭簧相对应的一弹块，在该弹块外侧边具有一弹块倾斜面。
作为本实用新型的进一步改进，还包括设置于基座与键帽之间且围设于盖子与导芯组件外围的一平衡架，该平衡架包括下端连接于基座上且上端连接于键帽中的一平衡杆A、及下端连接于基座上且上端连接于键帽中的一平衡杆B，该平衡杆A与平衡杆B中部交叉设置。

如图1、图6与图7所示，所述导芯组件4包括一外导芯41与一内导芯42，其中，该外导芯41包括一按压凸块411、及向外凸设于按压凸块411边缘的外卡沿412，在该按压凸块411上开设有一小穿孔4111；该内导芯42包括由下至上穿出小穿孔4111的一按压凸起421、及向外凸设于按压凸起421边缘且卡设于按压凸块411下方的内卡沿422；在所述外导芯41外侧边上开设有与弹动凸块523相匹配的一让位槽413，在该让位槽413下内侧壁上具有一导向斜面4131。
如图1与图4所示，在所述基座2上且位于外导芯41外围扣合有一盖子6，在该盖子6上开设有供按压凸块411穿出的一大穿孔61，对导芯组件4起到限位作用。
如图4所示，在所述内导芯42的按压凸起421下端面向上凹设有一内导芯导槽4211，在该内导芯导槽4211中部向下凸设有一导轴4212；在所述基座2上且位于按压凸起421正下方向上凸设有一导柱21，在该导柱21中心轴方向上向下凹设供导轴4212插入的一基座导槽211；所述导轴4212与导柱21外套设有一复位弹簧7，且该复位弹簧7上端嵌入于内导芯导槽4211中，下端围设于导柱21外围。
由动片52上的弹动凸块523与外导芯41上的让位槽413相配合，在按键开关处于自然未按压状态时，动片52上的弹动凸块523与外导芯41外侧边(即让位槽413下部)相抵触，使动片52的弹动部5221向外弹，即动片52的动触点与静片51的静触点512分离，按键开关处于断开状态；而向下按压键帽3时，导芯组件4下移，动片52上的弹动凸块523嵌入外导芯41的让位槽中，使动片52的弹动部5221复位回弹，从而使动片52的动触点与静片51的静触点512相接触，按键开关处于导通状态。
在本实施例中，由导芯组件4的特殊结构设计，在向下按压键帽3时，带动内导芯42下移至按压凸起421上端面与外导芯41的按压凸块411上端面齐平，获得由内导芯42产生的前段按压行程，继续按压，带动外导芯41与内导芯42一同下移，获得由外导芯41与内导芯42产生的后段按压行程，以获得高的总按压行程。
在本实施例中，为了提高用户体验，在按键开关中增设发声结构，如图1与图3所示，在所述基座2上且位于外导芯41外侧边设置有一扭簧8；在该外导芯41的外侧边设置有与扭簧8相对应的一弹块414，在该弹块414外侧边具有一弹块倾斜面。由外导芯41的弹块414不断的弹动扭簧8，使扭簧8敲打基座1或键帽3实现发声效果。
为了进一步提供按键开关的按压平衡性，使不管按压键帽3上的任一位置均能导通，如图1与图4所示，本实施例按键开关还包括设置于基座2与键帽3之间且围设于盖子6与导芯组件4外围的一平衡架9，该平衡架9包括下端连接于基座2上且上端连接于键帽3中的一平衡杆A 91、及下端连接于基座2上且上端连接于键帽3中的一平衡杆B 92，该平衡杆A 91与平衡杆B 92中部交叉设置。
为了使按键开关产生发光效果，如图1、图3与图4所示，在所述基座2上设置有连接至PCB板1的一LED灯10。
为了进一步缩短按键开关的整体高度，使产品向薄型化发展，如图1所示，本实施例在所述PCB板1上开设有一沉板孔11，该基座2下端中部嵌入沉板孔11中，占用PCB板1部分位置，使按键开关的整体高度缩短；同 时，该基座2通过若干固定脚22固定于PCB板1上，在该PCB板1上开设有供固定脚22插入的固定孔12、及供插脚(521,511)插入的插孔13。
以上所述，仅是本实用新型的较佳实施例而已，并非对本实用新型的技术范围作任何限制，故采用与本实用新型上述实施例相同或近似的技术特征，而得到的其他结构，均在本实用新型的保护范围之内。
