Description

柔性扁平电缆插座
本申请要求在2016年3月31日提交中国专利局、申请号为201620262772.7、发明名称为“柔性扁平电缆插座”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及电子电路技术领域，例如涉及一种柔性扁平电缆插座。
背景技术
柔性扁平电缆是指用于各种电子器件内部信号连接的新型扁平数据线缆。柔性扁平电缆最早应用于汽车中，20世纪80年代日本汽车制造厂为找到一种更加轻薄、节能的线材来取代奥迪可变气门升程系统(Audi Valvelift System，AVS)组合电束线用于轿车中，在日本三菱电线工业的协助下，经历8年的设计研究，最终成功研制出这种新型电缆，并命名为柔性扁平电缆。
柔性扁平电缆插座是在印刷电路板上用于插接柔性扁平电缆的专门插座。图1及图2分别示出了所述柔性扁平电缆插座的正面视图及侧视图。参见图2，柔性扁平电缆插座11的上边沿111与下边沿112在竖直方向上保持平齐。这样，如图1中示出的那样，在将所述柔性扁平电缆插座11连接至印刷电路板12上之后，所述柔性扁平电缆插座11的底面与所述印刷电路板之间不能完全的做到紧密结合。其结果是，柔性扁平电缆插座11的下边沿112与印刷电路板12之间存在一定的缝隙13。这样就使得柔性扁平电缆插接时，容易将被插接的柔性扁平电缆(Flexible flat cable，FFC)插入至上述缝隙13之中，造成柔性扁平电缆的误插接。而在自动化生产的流水线作业中，上述误插接发生的概率更高。
发明内容
本申请实施例提供了一种柔性扁平电缆插座，以提高柔性扁平电缆在柔性扁平电缆插座上的插接准确率。
本申请实施例提供了一种柔性扁平电缆插座，包括插座本体及柔性扁平电缆插口，其中，所述柔性扁平电缆插口的两侧分别具有上边沿及下边沿，所述下边沿邻近印刷电路板设置，以及在所述下边沿处设置有突出于所述上边沿的 凸台。
可选的，所述凸台与所述插座本体相接触处设置有倒角。
可选的，所述凸台的顶面为水平面。
可选的，所述凸台的顶面为由接近所述柔性扁平电缆插口向远离所述柔性扁平电缆插口向下倾斜的倾斜面。
可选的，所述凸台的宽度与所述柔性扁平电缆插口的宽度相等。
可选的，所述凸台的宽度与所述柔性扁平电缆插座的宽度相等。
可选的，所述凸台的宽度大于所述柔性扁平电缆插座的宽度。
可选的，所述凸台的第一厚度在0.1mm至0.3mm之间。
可选的，在所述柔性扁平电缆插口内，设置有多个金属触点。
可选的，多个所述金属触点之间的间距为0.5mm、0.8mm、1.0mm、1.25mm或者2.54mm。
本申请实施例提供的柔性扁平电缆插座，通过在所述抵近电路板边沿处设置有突出于所述远离电路板边沿的凸台，使得柔性扁平电缆在插接时不易被误插入柔性扁平电缆插座与印刷电路板之间的缝隙，提高了柔性扁平电缆在所述柔性扁平电缆插座上的插接准确率。
附图说明
一个或多个实施例通过与之对应的附图中的图片进行示例性说明，这些示例性说明并不构成对实施例的限定，附图中具有相同参考数字标号的元件表示为类似的元件，除非有特别申明，附图中的图不构成比例限制。

具体实施方式
下面结合附图和实施例对本申请作详细地说明。可以理解的是，此处所描述的实施例仅仅用于解释本申请，而非对本申请的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。在不冲突的情况下，本申请实施例中的特征可以任意组合。
本申请实施例提供了柔性扁平电缆插座的一种技术方案。在该技术方案中，所述柔性扁平电缆插座本体的前方，靠近所述插座本体的下边沿的位置，还设置了凸台。有了这样的突出所述插座本体的上边沿的凸台设置，所述柔性扁平电缆插座上柔性扁平电缆的插接准确率将明显提升。
所述柔性扁平电缆插座，又称为柔性扁平电缆电连接器，或者FFC电连接器，一般焊接在印刷电路板上，为了能够方便的插接柔性扁平电缆。
图3示出了本申请实施例提供的柔性扁平电缆插座的正面视图。参见图3，所述柔性扁平电缆插座包括插座本体31。在所述插座本体的正面设置有柔性扁平电缆插口32，可以用于插接所述柔性扁平电缆使用。在所述柔性扁平电缆借口32的内部设置有多个金属触点，以在所述柔性扁平电缆插接至所述柔性扁平电缆插口32之后，保持与所述柔性扁平电缆中信号线的信号电连接。
可选的，多个金属触点之间的间距可以是0.5mm、0.8mm、1.0mm、1.25mm或者2.54mm，以匹配不同规则的柔性扁平电缆。
在所述柔性扁平电缆插口32的上方及下方，分别是所述插座本体31的上边沿及下边沿。待所述柔性扁平电缆插座焊接至印刷电路板上之后，所述插座本体31的下边沿相较于上边沿更接近于印刷电路板。
本申请实施例提供的柔性扁平电缆插座相较于相关的柔性扁平电缆插座，不同之处在于，在插座本体31的下边沿处，增设了突出于所述上边沿的凸台33。有了上述的凸台，在连接柔性扁平电缆时，柔性扁平电缆就不再轻易被误插接 至所述插座本体31与印刷电路板之间的缝隙，因此能够提高插接准确率。
图4给出了所述柔性扁平电缆插座的侧面视图。参见图4，所述凸台33突出了所述插座本体31的其他部分，并且其顶面采用斜面。所述斜面的倾斜方向是自接近所述插座本体31的位置向远离所述插座本体31的位置而逐渐向下倾斜，能够更好的保证柔性扁平电缆的顺利插接。
所述凸台的第一厚度可以在0.1mm至0.3mm之间。所述第一厚度是指测量所述凸台厚度最大的部位而得到的厚度数值。
图5是图4的I部局部放大图。参见图5，在所述凸台33与所述插座本体31相接触的位置还可以设置有倒角331。有了所述倒角331的弧形缓冲，能够更为方便柔性扁平电缆的插接。
另外，图6是所述柔性扁平电缆插座的顶面视图。
需要说明的是，虽然图3至图6示出的实施例中，所述凸台33的顶面是倾斜的斜面。但是，所述凸台33也可以是水平面，本申请对此不作限制。
还有，虽然图3至图6示出的实施例中，所述凸台33的宽度等于所述柔性扁平电缆插口的宽度。但是，所述凸台33的宽度还可以等于所述柔性扁平电缆插座的宽度，也就是所述插座本体31的宽度，甚至可以大于所述柔性扁平电缆插座的宽度。
以上所述仅为本申请的可选实施例，并不用于限制本申请，对于本领域技术人员而言，本申请可以有各种改动和变化。
工业实用性
本申请实施例提供的柔性扁平电缆插座，提高了柔性扁平电缆在所述柔性扁平电缆插座上的插接准确率。
