Description

用于液晶显示器的荧光灯组装体
技术领域
本发明涉及液晶显示器背光模组的用于液晶显示器的荧光灯组装体，尤其是涉及能够防止荧光灯破裂的用于液晶显示器的荧光灯组装体。
背景技术
液晶显示器为一种非自发光显示装置，因此，需要设置背光模组来提供光源，根据背光模组中光源的位置不同，可分为侧光式背光模组及直下式背光模组。背光模组中最常用的光源为荧光灯(例如冷阴极荧光灯)和发光二极管(LED)等。
侧光式背光模组需要用一种用于液晶显示器的荧光灯组装体，将荧光灯固定在背光模组的内部一侧。这种现有的用于液晶显示器的荧光灯组装体上装配荧光灯，或装配完毕后配线时，皆需要拉动导线进行。当导线的拉力过大时，经常发生荧光灯破裂，这种荧光灯破裂的问题占产品不良率的10％，位居第三位。
请参阅图1，为现有的用于液晶显示器的荧光灯组装体的剖面图。现有的荧光灯包括：灯管1，灯管1内部具有电极，灯管1外侧突出部分为电极的引线11。用于液晶显示器的荧光灯组装体包括，用于固定荧光灯的固定架2，固定架2具有荧光灯固定管及导线固定管，荧光灯的灯管1插入荧光灯固定管而固定，导线4从导线固定管进入固定架2内与荧光灯的引线11连接，导线4与引线11在固定架2内用锡焊法焊接，形成焊点3，且导线4和引线11相互垂直。上述现有技术的用于液晶显示器的荧光灯组装体，为了防止拉扯导线引起的灯管的破裂问题，是将导线和引线垂直焊接，避免导线的拉力直接作用到荧光灯上，但是当导线拉力过大时，仍然会导致荧光灯破裂。
发明内容
本发明的目的是提供一种用于液晶显示器的荧光灯组装体，能够减少灯管破裂的几率。
为实现上述目的，本发明提供了一种用于液晶显示器的荧光灯组装体，包括：
固定架，具有荧光灯固定管和导线固定管；
导电弹性件，位于固定架内部，一端通过荧光灯固定管与所述荧光灯连接；
导线，位于导线固定管内，该导线的一端与导电弹性件的另一端连接。
所述的用于液晶显示器的荧光灯组装体，其中所述荧光灯包括灯管、灯管内的电极和突出于灯管一侧的引线，所述引线与导电弹性件的一端连接。
所述的用于液晶显示器的荧光灯组装体，其中所述导电弹性件的一端通过第一连接部与所述引线连接，另一端通过第二连接部与所述导线的一端连接。
所述的用于液晶显示器的荧光灯组装体，其中所述导电弹性件是弹簧或弹性导线。
所述的用于液晶显示器的荧光灯组装体，还包括弹性块，其套设在所述弹性导线上。
所述的用于液晶显示器的荧光灯组装体，其中所述弹簧的宽度大于所述导线固定管宽度。
所述的用于液晶显示器的荧光灯组装体，其中所述弹性块的宽度大于所述导线固定管宽度。
由上述技术方案可知，本发明通过在固定架内部设置导电弹性件，当装配荧光灯或布设导线而拉扯导线时，导线上产生的向下的拉力，拉力首先会作用到导线上连接的导电弹性件上，导电弹性件拉伸形变，而起到缓冲作用，继而可避免荧光灯的灯管破裂。
下面通过附图和实施例，对本发明的技术方案做进一步的详细描述。

具体实施方式
请参阅图2，为本发明用于液晶显示器的荧光灯组装体的第一实施例的剖面图，其包括：固定架2、导电弹性件和导线4。其中，固定架2具有荧光灯固定管和导线固定管，荧光灯插入荧光灯固定管而固定，导线4位于导线固定管内，荧光灯与导线4通过导电弹性件连接。本实施例中的导电弹性件是具有导电性的弹簧21，位于固定架2内部。
当装配荧光灯或布设导线而拉扯导线时，导线上产生的向下的拉力，拉力首先会作用到导线上连接的导电弹性件上，导电弹性件拉伸形变，而起到缓冲作用，继而可避免荧光灯的灯管破裂。
具体而言，荧光灯包括灯管1、灯管内的电极12和突出于灯管一侧的引线11，引线11通过第一连接部211与弹簧21的一端连接。导线4的一端通过第二连接部212与具有与弹簧21的另一端连接。所述第一连接部211和第二连接部212为锡焊形成的焊点。
另外，本实施例中荧光灯固定管与导线固定管相互垂直，使得荧光灯的装配方向垂直于导线的装配方向，避免导线的拉力直接作用到荧光灯上。
另外，弹簧21的宽度大于导线固定管宽度，拉动导线4时，弹簧21不会从荧光灯固定管中拉出进入导线固定管中而失去缓冲作用。
请参阅图3，为本发明用于液晶显示器的荧光灯组装体的第二实施例的剖面图。其包括：固定架2、导电弹性件和导线4。其中，固定架2具有荧光灯固定管和导线固定管，荧光灯插入荧光灯固定管而固定，导线4位于导线固定管内，荧光灯与导线4通过导电弹性件连接。本实施例中的导电弹性件是弹性导线22及套设在弹性导线22上的弹性块23，位于固定架2内部。
当装配荧光灯或布设导线而拉扯导线时，导线上产生的向下的拉力，拉力首先会作用到导线上连接的弹性导线上，弹性导线拉伸形变，而起到缓冲作用，继而可避免荧光灯的灯管破裂。另外，荧光灯被拉动时，弹性块也能起到一定的缓冲作用，更保障了荧光灯的良品率。
具体而言，荧光灯包括灯管1、灯管内的电极12和突出于灯管一侧的引线11，引线11通过第一连接部211与弹性导线22的一端连接。导线4的一端通过第二连接部212与具有与弹性导线22的另一端连接。所述第一连接部211和第二连接部212为锡焊形成的焊点。
另外，本实施例中荧光灯固定管与导线固定管相互垂直，使得荧光灯的装配方向垂直于导线的装配方向，避免导线的拉力直接作用到荧光灯上。
另外，所述弹性块23的宽度大于导线固定管宽度，拉动导线时，弹性导线22和弹性块23不会从荧光灯固定管中拉出进入导线固定管中而失去缓冲作用。
另外，也可以将导线或引线用弹性导电材料制作，使其本身具有缓冲作用，或将固定架内的导线或引线的部分做成如弹簧一样的弹性弯曲结构，也可以达到上述减少灯管破损的效果。
最后应说明的是，以上实施例仅用以说明本发明的技术方案而非对其进行限制，尽管参照较佳实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对本发明的技术方案进行修改或者等同替换，而这些修改或者等同替换亦不能使修改后的技术方案脱离本发明技术方案的精神和范围。
