Description

一种软排线连接器 技术领域
本发明涉及一种排线连接器，尤其是一种软排线连接器。
背景技术
柔性软排线通常包括FPC排线和FFC排线，软排线可以任意选择导线数目及间距，使联线更方便，大大减少电子产品的体积，减少生产成本，提高生产效率，最适合于移动部件与主板之间、PCB(线路板)板对PCB板之间、电器设备中作数据传输线缆之用。FPC/FFC排线一般与连接器连接，连接器焊接在线路板上，常用的连接器包括底座、接触端子和掀盖，接触端子固定在底座上，掀盖铰接在底座上，FPC/FFC排线插在接触端子内，掀盖将排线压紧在接触端子上。由于连接器需要焊接在线路板上，因此需要占用线路板上的面积，并且焊接导致工序多，插入或拔出FPC/FFC排线时均需要打开连接器的掀盖，使用不方便。
发明内容
为解决上述问题，本发明提供一种与线路板活动连接，插拔方便，不占用线路板空间的一种软排线连接器，具体技术方案为：
一种软排线连接器，包括连接座，所述连接座的一端设有排线插槽和端子插槽，所述端子插槽与排线插槽垂直，且与排线插槽相通，所述端子插槽设有多个，所述多个端子插槽等间距设置，所述连接座的另一端设有线路板插槽，所述线路板插槽与排线插槽上下交错设置，所述线路板插槽与端子插槽相通；及接触端子，所述接触端子设有多个，所述多个接触端子分别固定在端子插槽内，所述接触端子上设有内压紧部和外压紧部，所述内压紧部位于排线插槽内，所述外压紧部位于线路板插槽内；排线活动插在排线插槽内，所述排线与内压紧部活动连接，线路板活动插在线路板插槽内，所述线路板与外压紧部活动连接。
通过采用上述技术方案，在线路板上设有金手指，金手指通过接触端子与排线连接，由于金手指占用的线路板的面积小，极大的减小了线路板的面积，使线路板能够实现小型化。
