Description

一种金手指连接装置 技术领域
本实用新型属于液晶屏生产检测领域，尤其涉及液晶屏的检测设备领域。
 背景技术
液晶显示屏在方方面面的应用给人们带来了方便实用，由于液晶屏本身所具有的特性，液晶显示屏在生产过程中需要必要的检测步骤以保证其合格率，现有技术中对液晶显示屏的检测工作采用插卡模式进行，所谓插卡模式是将检测设备的连接件设计成插槽式的连接槽，将需检测的液晶显示屏的连接电极插入连接槽中，然后通过检测设备对液晶显示屏进行检测，连接槽中设有与液晶显示屏的连接电极相对应的多个连接弹片，显示屏进入连接槽中，所述连接弹片具有向下的压力，迫使连接弹片分别与连接电极的各个电极点紧密连接，检测完毕之后将液晶显示屏从连接槽中取出，此类检测设备的连接槽具有三个缺点：
1液晶显示屏的连接电极受到至少两次连接弹片的磨损，由于连接电极的镀层很薄，在受磨损后容易脱落，检测时没有问题，但拔出连接电极的时候镀层的脱落容易致使显示屏成为一个标注为合格品的问题显示屏；
2检测过程对连接弹片也会构成磨损，连接弹片上的电极涂层也会在长期使用后发生脱落的现象，容易导致检测结果出现错误，另外也容易发生弹片弹力不足，连接出现虚连同样出现检测结果错误；
3连接槽具有多个连接弹片，其生产成本较高，同时又具有上述第2点的问题，在出现了问题后，其更换成本高，整体会提高液晶显示屏的生产成本。
 技术问题
本实用新型的目的在于提供一种金手指连接装置，旨在解决现有技术中液晶显示屏的连接电极容易受到检测设备的连接槽磨损的问题。
 技术解决方案
本实用新型是这样实现的，一种金手指连接装置，包括上夹板和下夹板，以及置于所述上夹板内表面的胶垫，所述胶垫具有多个可与金手指的连接电极分别相对应的导电条, 所述下夹板内表面设有可防止对所述连接电极磨损的保护层。
优选地，所述胶垫表面呈凸起的弧面设计。
 有益效果
依借上述技术方案，本实用新型所提供的金手指连接装置在使用时，将需要检测的液晶屏的金手指置于所述下夹板上，所述上夹板置于所述液晶屏的金手指上方，并且使所述导电条与所述金手指的连接电极一一对应，所述导电条通过电缆与检测设备连接，所述上夹板对所述金手指进行下压，促使所述导电条与液晶屏的金手指紧密连接充分接触，能够良好的将检测设备的检测信号通过所述导电条输入到液晶屏中从而进行检测，由于所述胶垫的本身物理特性，在受到所述上夹板的下压力时，所述胶垫会发生轻微变形，可保证所述导电条与金手指的连接电极紧密连接充分接触，由于在所述下夹板内表面增加了保护层，进一步避免了金手指连接电极下表面被磨损。
