Description

直下式背光模组及布线装置
技术领域
本发明涉及显示技术领域，尤其涉及一种直下式背光模组及布线装置。
背景技术
常见的背光模组主要分为直下式和侧入光式两类，直下式背光模组一般不需要导光板，所以在成本上较侧入光式有优势，且直下式背光模组更利于局域控光技术的应用。
一般直下式背光模组的LED(Lighting Emitting Diode，发光二极管)灯珠均匀分布在后壳上，其通过电路划分为多个区块，所以也需要更多的连接线将其LED灯条和整机电源板进行电性连接，比侧入式背光模组的连接线接入方式复杂，连接工艺上也比较繁琐，组装效率较低。
发明内容
鉴于现有技术存在的不足，本发明提供了一种直下式背光模组及布线装置，可以有效降低连接线的布线难度，提高背光模组的组装效率。
为了实现上述的目的，本发明采用了如下的技术方案：
一种FFC(Flexible Flat Cable，柔性扁平电缆)连接器，包括：
底座；
上盖，可旋转地铰接于所述底座上；
至少一个弹片，所述弹片设于所述底座上且所述弹片的顶端凸出于所述底座上表面，所述弹片的底端伸出所述底座下表面；
所述上盖的自由端设有弯折的延伸部，所述延伸部用于卡设在所述底座上。
其中，所述弹片为多个，平行设于所述底座上，且所述弹片的延伸方向平行于所述上盖的旋转轴。
其中，FFC连接器还包括凸设于所述底座上表面的定位件。
其中，所述定位件为四个，分别设于所述底座的四个角上。
其中，所述定位件为凸柱。
本发明还提供了一种直下式背光模组，包括后壳、多条平行且间隔设置的灯条组件、FFC排线及上述FFC连接器，所述灯条组件固定设于所述后壳内，每个所述灯条组件上设有一个所述FFC连接器；所述FFC排线夹设于所述FFC连接器的所述底座和所述上盖之间，所述FFC排线上设有与所述弹片电连接的导电端子，所述弹片的底端与所述灯条组件电连接。
其中，所述FFC排线的宽度方向设有缺口部，所述底座上表面凸设有定位件，且所述定位件设于所述缺口部内。
其中，所述FFC排线与所述灯条组件的长度方向正交设置。
其中，所述FFC连接器设于所述灯条组件的一端，且所述上盖的旋转轴垂直于所述灯条组件的长度方向。
另外，本发明还提供了一种上述直下式背光模组的布线装置，包括绕线轮、滚压轮、弹性缓冲轴和冲裁刀组件，所述绕线轮上卷有所述FFC排线，所述绕线轮沿各个所述FFC连接器的连线依次滚过各个所述FFC连接器，同时所述滚压轮在所述弹性缓冲轴的按压下沿各个所述FFC连接器的连线滚动并按压所述FFC排线，所述冲裁刀组件用于裁剪所述FFC排线。
本发明设计了一种夹持固定FFC排线的FFC连接器，可以很好地固定FFC排线并实现FFC排线与灯条组件的可靠电连接；同时，本发明的直下式背光模组内具有多个间隔平行设置的灯条组件，每个灯条组件设有一个FFC连接器，FFC排线的插接端通电后，FFC排线可通过各个FFC连接器实现与各个灯条组件的电连接，布线方式简单且固定可靠，有效降低了FFC排线的布线难度，大大提高了背光模组的组装效率；同时布线方式自动化程度更高，布线工艺大大简化。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例1
参阅图1，本发明的FFC(Flexible Flat Cable，柔性扁平电缆)连接器包括：底座11、上盖12、弹片13和定位件14，其中底座11用于固定在灯条组件上，上盖12可旋转地铰接于底座11上，弹片主要13用于将外部电源与灯条组件实现导通，弹片13设于底座11上且弹片13的顶端凸出于底座11上表面，弹片13的底端伸出底座11下表面与灯条组件电连接。弹片13的顶端高出底座11的上表面，FFC排线40与弹片13相对的面设有与弹片13电接触的导电端子，起到导电作用的同时还能对放在底座11上的FFC排线40起到弹性抵接的作用，保证FFC排线40与弹片13的可靠电接触。
上盖12的自由端设有弯折的延伸部15，延伸部15用于卡设在底座11上，从而将FFC排线40夹设于其中。
多个弹片13平行设在底座11上，弹片13的延伸方向平行于上盖12的旋转轴。这里，底座11上开设有多条平行的容纳槽16，弹片13固定设置在其中。
为了进一步保证FFC排线40的固定效果，防止FFC排线倾斜或错位，导致其与弹片13的接触不良，底座11上表面凸设有至少一个定位件14，FFC排线40的宽度方向设有缺口部41，定位件14设于缺口部41内。本实施例的定位件14为四个，分别设于底座11的四个角上，定位件14为凸柱，可以理解的是，定位件14也可以为凸块等结构。
本发明的FFC连接器在夹持固定FFC排线的同时还能实现FFC排线与灯条组件的可靠电连接，保证了弹片与FFC排线的接触精度和可靠性。
实施例2
如图2和图3所示，本发明实施例的直下式背光模组包括后壳20、多条平行且间隔设置的灯条组件30、FFC排线40及FFC连接器10，灯条组件30固定设置在后壳20内，在每个灯条组件30上对应设有一个FFC连接器10。FFC排线40夹设于FFC连接器10的底座11和上盖12之间，结合图4，FFC排线40上设有与弹片13电连接的导电端子42，弹片13的底端与灯条组件30电连接。
灯条组件30包括基板31、LED灯珠32和透镜33。FFC排线40的宽度方向设有缺口部41，底座11的上表面凸设有定位件14，定位件14设于缺口部41内。
其中，FFC排线40与灯条组件30的长度方向正交设置。
进一步地，FFC连接器10设于灯条组件30的一端，且上盖12的旋转轴垂直于灯条组件30的长度方向。
本发明的直下式背光模组内具有多个间隔平行设置的灯条组件，每个灯条组件设有一个FFC连接器，FFC排线的插接端通电后，FFC排线可通过各个FFC连接器实现与各个灯条组件的电连接，布线方式简单且固定可靠，有效降低了FFC排线的布线难度，大大提高了背光模组的组装效率。
实施例3
如图4和图5，FFC排线40包括缺口部41、导电端子42、插接端子43、粘贴部分44和离型膜45，插接端子43位于FFC排线40的长度方向的两端，导电端子42位于多个插接端子43之间，每个导电端子42和插接端子43都包括由多个触点，以保证与灯条组件30的接触可靠性。离型膜45剥离后，滚动绕线轮100，弹性缓冲轴102在外力作用下弹性按压滚压轮101，从而按压FFC排线40，利用粘贴部分44将FFC排线40粘贴在后壳20和相应的FFC连接器10的底座11上。
本发明的实施例的布线装置可应用于本发明实施例2的直下式背光模组，包括绕线轮100、滚压轮101、弹性缓冲轴102和冲裁刀组件103，绕线轮100上卷有FFC排线40，沿各个FFC连接器10的连线依次滚过各个FFC连接器10，同时滚压轮101在弹性缓冲轴102的按压下沿各个FFC连接器10的连线滚动并按压FFC排线40，冲裁刀组件103用于裁剪FFC排线40，沿冲裁线48将绕线轮100上的一段插接端子43剪切成两段。
本实施例的布线装置使得布线方式自动化程度更高，布线工艺可以大大简化，提高了组装、布线效率。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
