Description

一种夹线电连接器
技术领域
本发明涉及电子技术领域，具体涉及电连接器。
背景技术
电连接器，与导线连接，实现电子或电气设备的正常运行。其中，与电连接器连接的导线容易松动而导致接触不良，影响电子或电气设备的运行。
发明内容
本发明所解决的技术问题：实现电连接器与导线的稳定连接。
为解决上述技术问题，本发明提供如下技术方案：一种夹线电连接器，包括连接器本体、设置在连接器本体中的夹线弹片和导电弹片，所述连接器本体上开设导线插入孔，夹线弹片和导电弹片位于所述导线插入孔的两侧，用于夹持插入所述导线插入孔的导线；所述连接器本体上滑动配合有推杆，推杆上设有弹片压迫结构，在弹片压迫结构的作用下，所述夹线弹片向导电弹片方向压迫导线。
按上述技术方案，导线插入所述导线插入孔，推杆相对连接器本体滑动，其上的弹片压迫结构作用于夹线弹片，夹线弹片将导线压紧在导电弹片上，实现电连接器与导线的稳定连接。
作为上述技术方案的一种改进，所述推杆上设有第一导线弹片止退结构，所述弹片上部设有与所述第一导线弹片止退结构配合的第二导线弹片止退结构；所述第一导线弹片止退结构位于所述弹片压迫结构的后方。
按上述改进，向前滑动的推杆，其上的弹片压迫结构首先作用于夹线弹片，使夹线弹片向下压紧导线，之后，第一导线弹片止退结构与夹线弹片上的第二导线弹片止退结构配合，防止推杆向后滑动。需退出所述推杆时，动作所述推杆，使第一导线弹片止退结构和第二导线弹片止退结构脱离。
与夹线弹片配合设计的推杆，其直线运动产生向下压迫夹线弹片的效果，并使夹线弹片维持此种压迫状态，迫使导线与导电弹片紧密接触，提高电连接器与导线连接的稳定性。

如图3，所述弹片上部21设有与所述第一导线弹片止退结构配合的第二导线弹片止退结构23，作为一种优选，所述第二导线弹片止退结构23为设置在所述弹片上部21上的凹槽。
实际操作中，参考图2、图3，导线50插入所述导线插入孔11，向前推动所述推杆40，推杆沿滑槽前行，其前端的楔形结构首先作用于夹线弹片20的弹片上部21，弹片上部被迫下行，迫使弹片下部22压迫导线50，导线被压紧在导电弹片30上。当推杆40向前运行至极限位置时，其上的凸点与所述弹片上部21的凹槽配合，起到止退的作用。其中，推杆40上设有与连接器本体10配合的限位结构，对推杆在滑槽中的运行幅度进行限制。
任一推杆40的前端设有退线点43，需退线时，按压所述退线点，推杆40上的凸点与夹线弹片20上的凹槽松脱，后拉所述推杆40，夹线弹片的弹性势能得到释放，不再紧固导线50，导线可从导线插入孔11中抽出，实现退线。

实际操作中，参考图5、图6，导线50插入所述导线插入孔11，端部抵在所述分隔结构13上。向前推动所述推杆40，推杆沿滑槽前行，其前端的楔形结构迫使夹线弹片20压迫导线50，导线被压紧在导电弹片30上。推杆40向前运行，直至与所述分隔结构13相抵，其上的凸点与所述弹片上部21的凹槽配合，起到止退的作用。
需退线时，利用工具向后推动推杆40尾端的退线槽44，推杆40上的凸点与夹线弹片20上的凹槽松脱，后推所述推杆40，夹线弹片的弹性势能得到释放，不再紧固导线50，导线可从导线插入孔11中抽出，实现退线。
