Description

一种用于充电对接的电连接器 技术领域
本实用新型涉及电连接器技术领域，特别涉及一种用于充电对接的电连接器。
 背景技术
在特种车自动充电领域，地面端的授电设备通过末端电连接器与车端的受电端铜排进行对接充电连接。因为电连接器与铜排须要达到一定的对接压力后方可安全充电，所以电连接器设计成弹性机构。目前的电连接器的电触头通过螺旋压簧弹性连接在固定座上，铜编织带固定连接在电触头和固定座上。壳体内部包覆固定座、电触头、螺旋压簧和铜编织带。电触头可沿壳体内壁做滑移运动，螺旋压簧和铜编织带随之做同步的伸缩运动。该电连接器可通过固定座的螺纹部分固定在导电元件上，比如铜排。电流经过固定座、铜编织带和电触头传导给车端铜排。
现有技术的缺陷或不足：该电连接器存在一个较大的缺陷：由于电触头完全固定在螺旋压簧上实现弹性连接，而螺旋压簧的径向位移误差很大导致电触头会径向偏移，电触头在轴向压缩过程中该径向偏移量会使电触头的外圆面与壳体内壁产生较大摩擦力而卡滞（尤其在多个电连接器对接时更明显），极大影响正常的充电作业。此外电连接器本体为圆柱面，安装无扳手卡紧位置，电连接器固定安装较为困难。
 实用新型内容
为了解决现有技术存在的电触头在轴向压缩过程中产生的径向偏移量会使电触头的外圆面与壳体内壁产生较大摩擦力而卡滞的问题，本实用新型提供一种减少电触头径向偏移，从而减小电触头出现卡滞几率的用于充电对接的电连接器。
本实用新型解决其技术问题所采用的技术方案是：
一种用于充电对接的电连接器，包括壳体、固定座、电触头和弹性件，所述的固定座与电触头电连接，所述的弹性件用于将电触头的头部顶出所述的壳体，所述的壳体内设有用于电触头滑动导向的导向结构。
进一步的，所述的电触头与壳体之间沿垂直于电触头的滑动方向具有缝隙。相当于将电触头与壳体隔离开，避免了电触头与壳体之间的卡滞现象。
进一步的，所述的导向结构包括与电触头接触的滚动体。
进一步的，所述的导向结构包括安装在壳体内的轴承座，电触头与轴承座之间设置有滚珠滑套。滚珠滑套与电触头之间为滚动摩擦力，电触头的运动更加顺滑；
进一步的，所述的固定座上设有弹簧触指，所述的电触头与弹簧触指接触。
进一步的，所述的固定座与壳体可拆卸固定连接。采用可拆卸连接方式，可以便于更换弹簧触指。
进一步的，所述的壳体内设有第一台阶，所述的固定座将轴承座抵在第一台阶的台阶面上。
进一步的，还包括用于限制电触头被顶出的长度的限位结构，所述的限位结构包括设置在电触头上的凸环，所述的壳体上设有用于卡住凸环的第二台阶。
进一步的，所述的弹性件包括矩形弹簧，所述的矩形弹簧置于电触头与轴承座之间。
进一步的，所述的壳体上设有便于工具夹住的豁槽。
有益效果
（1）本实用新型的用于充电对接的电连接器增加导向结构，电触头经过导向结构导向进行轴向滑移压缩，减少径向偏移，减小电触头出现卡滞的几率；
（2）电触头与壳体之间沿垂直于电触头的滑动方向具有缝隙，如采用的是圆柱形的电触头，从而电触头滑动过程中，电触头外圆面与壳体内壁不再接触，相当于将电触头与壳体隔离开，避免了电触头与壳体之间的卡滞现象；
（3）导向结构包括滚动体，电触头滑移压缩过程中的滚动摩擦力远小于之前的滑动摩擦力，使得电触头的压缩过程运动更加顺滑，阻力小，进一步避免了电触头与壳体之间的卡滞现象；

（5）通过固定座将轴承座抵靠在第一台阶的台阶面上，然后固定座与壳体固定可拆卸固定，整体结构更加紧凑。

固定座3与壳体2固定连接。固定座3和壳体2可焊接成一体件，优选的，固定座3与壳体2可拆卸固定连接，固定座3和壳体2之间可用螺钉连接，方便更换弹簧触指6。壳体2内设有第一台阶21，固定座3将轴承座7抵在第一台阶21的台阶面上。具体的，轴承座7和固定座3分别同轴安装在壳体2的内腔室中，轴承座7依靠第一台阶21和固定座3轴向定位。
本实用新型的电连接器还包括用于限制电触头1被顶出的长度的限位结构。限位结构包括设置在电触头1上的凸环，壳体2上设有用于卡住凸环的第二台阶22。弹性件包括矩形弹簧5，矩形弹簧5置于电触头1与轴承座7之间。矩形弹簧5穿设在轴承座7和壳体2组成的环形空间内，并且矩形弹簧5的预压力将电触头1压紧在壳体2的第二台阶22的台阶面上。
壳体2上设有便于工具夹住的豁槽23，豁槽23对称设置在壳体2的两侧，且两豁槽23的底面相互平行，这样为扳手等工具提供了卡紧位置，便于安装。
以上，仅为本实用新型较佳的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，根据本实用新型的技术方案及其实用新型构思加以等同替换或改变，都应涵盖在本实用新型的保护范围之内。
