为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说明。
如图1、图2和图5所示，本申请实施例提供的连接器10，包括线缆200和线缆连接器100。线缆200可以但不限于是柔性扁平线缆，线缆200设置有第一焊脚211，线缆连接器100配置为与待连接的电路板300连接固定，电路板300设置有第二焊脚310，线缆连接器100具有容置槽102，第一焊脚211收容于容置槽102内，容置槽102的底面开口，以使第一焊脚211与电路板300上的第二焊脚310直接接触。也就是说，线缆连接器100省去了起间接传导作用的插针，线缆连接器100只起到固定线缆200的作用，使第一焊脚211与第二焊脚310直接相抵，形成稳定的电连接。同时，第一焊脚211设置有第一助摩擦结构，以用于与第二焊脚310的相接面对应的凸起312和/或凹槽相 契合，即焊脚211与焊脚310可形成相咬合的结构，如此可增加焊脚211与焊脚310之间的摩擦力，可使线缆200不容易从线缆连接器100中脱落。
本实施例提供的连接器10，由于线缆200的第一焊脚211设置有第一助摩擦结构，线缆连接器100设有容置槽102，第一焊脚211在线缆连接器100的容置槽102中且与电路板300上的第二焊脚310直接接触，加强了第一焊脚211和第二焊脚310的连接强度，不需要插针来使线缆200与电路板300电连接，线缆连接器100结构简单，生产成本低，连接器10与印刷线路板300装配后的连接器组件20整体厚度变薄、体积变小，方便使用，且成本低，同时，通过助摩擦结构使得线缆200与电路板300电连接更加稳定，线缆200不容易从线缆连接器100脱落。
如图1、图8所示，在一实施例中，第一助摩擦结构设置在第一焊脚211的末端。在一实施方式中，第一助摩擦结构包括凹槽212和/凸起，即第一焊脚211的表面设置有凹槽212和/或凸起，该凹槽212和/或凸起与第二焊脚310的相接面对应的凸起312和/或凹槽相契合，第一焊脚211与第二焊脚310形成相咬合的结构，使线缆200与线缆连接器100形成更为稳定的装配。如图2所示，第一焊脚211上设置凹槽时，第二焊脚310设置凸起，如图3所示，第一焊脚211上设置凸起时，第二焊脚310设置凹槽；可以将所有的第一焊脚211上全部设置凹槽或全部都设置凸起，将所有的第二焊脚310全部都设置凸起或全部设置凹槽，如图1所示，各第一焊脚上分别设置有凹槽，各第二焊脚分别设置有凸起；如图4所示，也可以将各第一焊脚211混合设置，即各第一焊脚211中有的第一焊脚211设置有凹槽，有的第一焊脚211设置有凸起，各第二焊脚310对应混合设置。
线缆连接器100包括顶板110和侧板120，侧板120连接于顶板110相对 的两侧，侧板120与顶板110构成中空的壳体，侧板120设置为固定连接在电路板300上，顶板110和两侧的侧板120共同围成有固定第一焊脚211的容置槽102。线缆连接器101可以是由聚对苯二甲酸类塑料(Polyethylene terephthalate，PET)注塑成型的，即顶板110和两侧板120一体成型，容置槽102具有相对的前端和后端，前端供线缆200插入，容置槽102的前后端以及底面均开口，容置槽102的前端的开口形成线缆200的插入口，容置槽102底面的开口使线缆连接器100固定于电路板300时，第一焊脚211与第二焊脚310能直接接触以形成电连接。
在一实施例中，结合参考图5、图6所示，线缆连接器100还包括与侧板120连接且位于容置槽102后端的限位板，即容置槽102的后端再设置一限位板130，该限位板130的高度等于或小于侧板120的高度，如此，当线缆200插入容置槽102并与限位板130抵持时可知晓线缆200已插入到位，此时完成线缆200与线缆连接器100之间的装配。
在一实施方式中，两侧的侧板120连接固定在电路板300上。例如，使用工业胶将两个侧板120粘接固定在电路板300上，或者使用高频超声波焊接机将该两个侧板120焊接固定在电路板300上，超声波焊接其质量好，焊接后气密性好，且焊接效率高、成本低。
在一实施例中，两侧的侧板120均与顶板110垂直，线缆200整体结构更为稳定，占用空间也较小。此时容置槽102呈U形，侧板120的底面与电路板300连接固定。可以理解，侧板120也可以与顶板110呈角度设置，例如侧板120与顶板110之间的夹角为钝角。
在一实施例中，顶板110的底面设置为与线缆200的焊脚211粘接或焊接，即第一焊脚211上下面都是外露的，可通过粘接或焊接的方式将线缆200的焊 脚211固定在顶板110的底面，且将线缆连接器100固定在电路板300后，第一焊脚211直接与第二焊脚310抵接贴触。
在一实施例中，第一助摩擦结构的纵截面呈矩形、圆缺形、V形或梯形，也可以是其它规则的几何形状或不规则的形状。如图1、图2和图8所示，在一实施方式中，电路板300和线缆200的一端均设置有间隔平行的多个焊脚，每个第二焊脚310的表面凸出形成有横截面呈半圆形的凸起311，每个第一焊脚211对应凸起的位置形成分别形成有横截面呈半圆形的凹槽212，凸起311与凹槽212的相咬合结构使得线缆200不容易从线缆连接器100脱落。
本申请实施例提供的连接器组件20，包括电路板300和上述实施例的连接器10。电路板300设置有第二焊脚310，并且，该第二焊脚310设置有与第一助摩擦结构相契合的第二助摩擦结构，第一焊脚211收容在线缆连接器100的容置槽102内，线缆连接器100固定于电路板300，第一焊脚211与第二焊脚310直接接触。第二助摩擦结构包括设置于第二焊脚310的凸起311和/或凹槽，以和第一焊脚211的相接面相契合。可以理解，电路板300可以是印刷电路板(Printed Circuit Board，PCB)，电路板300也可以是装有元器件的电路板(Printed Circuit Board+Assembly，PCBA)。
操作时，将线缆200装固于线缆连接器100的容置槽102后形成连接器10，再将线缆连接器100固定在电路板300上，线缆200与电路板300上的凹槽和凸起对准，此时各第一焊脚211与第二各焊脚310分别直接接触，形成稳定的电连接，线缆200与电路板300实现电连接，由于线缆连接器100的结构简单，厚度小，使得连接器组件20整体厚度较薄，且制造成本降低，第一焊脚211与第二焊脚310形成相契合的结构可使线缆200不容易从线缆连接器100中脱落。
在一实施例中，如图7至图8所示，线缆200为柔性扁平线缆，柔性扁平线缆包括导线层210和贴合于导线层210上下表面的绝缘层220，导线层210的一端的下表面外露并形成多个第一焊脚211，第一焊脚211的顶面设置有补强板230，该补强板230设置为卡接于线缆连接器100的容置槽102内，使柔性扁平线缆的一端通过补强板230卡接线缆连接器100，并使线缆连接器100固定于电路板300时柔性扁平线缆的第一焊脚211与第二焊脚310直接接触。
补强板230的宽度适配于线缆连接器100的容置槽102的宽度，补强板230的一端延伸于线缆200的上表面的绝缘层220，补强板230与线缆200的绝缘层220一体注塑成型，补强板230可加强线缆200的机械强度。将补强板230卡装于容置槽102时，补强板230的顶面与顶板110的底面(容置槽的顶面)相贴触。
在另一实施例中，补强板230粘接或焊接固定于顶板110的底面(容置槽102的顶壁)，例如，通过高频超声波焊接机将该两个侧板120焊接固定在电路板300上。
在一实施例中，补强板230与线缆连接器100卡接，容置槽102的两侧壁与补强板230的侧壁之间分别形成有弹性卡持结构，补强板230插入容置槽102时，借助该弹性卡持结构能稳定地卡固在容置槽102中。两侧的侧板120对称设置有与弹性卡持结构连接的按压部，通过向线缆连接器100内部方向按压两侧的按压部，可使线缆连接器100的弹性卡持结构松开，以使补强板230能从容置槽102中拔出。
在其它实施例中，补强板230与线缆连接器100的卡接结构可采用较为简单的方式，例如，如图6、图8所示，在补强板230上宽度方向的两侧对称设置有定位缺口231，线缆连接器100的两个侧板120的对应位置活动设置有限 位件121，补强板230插入容置槽102的预定位置后，转动两侧的侧板120上的限位件121至预定位置后限位件121卡入定位缺口231中，使补强板230相对于线缆连接器100固定，实现柔性扁平线缆与线缆连接器100的装配。
在一实施例中，第一焊脚211连接固定在顶板110的底面(容置槽的顶面)，例如，第一焊脚211粘接或焊接固定在顶板110的底面，即柔性扁平线缆的第一焊脚211的上下表面都是裸露的，通过焊接或粘接的方式将焊脚211固定在顶板110上，以完成线缆200与线缆连接器100的装配。
在一实施例中，如图1、图7及图8所示，第二焊脚310设置有第二焊盘312，第一焊脚211的对应位置设置有第一焊盘213，第一焊盘213和第二焊盘312设置有相互配合的凸起和凹槽。在一实施方式中，第二焊盘312上设置有凸起311和/或凹槽，第一焊盘213上设置有凹槽212和/或凸起。
可以理解的是，如图8、图9所示，第二焊盘312可设置在各第二焊脚310的末端，而相邻第二焊脚310的长度可设置为不相等，如此，各第二焊脚310的第二焊盘312形成错位布设的结构，同时，第一焊脚211的第一焊盘213也形成错位布设的结构，以便于容置更多焊脚，提高焊接强度。如图8所示，第一焊盘213和第二焊盘312可呈圆盘状；如图9、图10所示，第一焊盘213和第二焊盘312的横截面呈矩形，第一焊盘213上间隔设置有两排凹槽212，各凹槽212的纵截面呈半圆形，第二焊盘312对应两排凹槽212的位置设置有两排凸起311，各凸起311的纵截面呈半圆形。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
