Description

端子结构
技术领域
本发明涉及端子结构。
背景技术
专利文献1中公开了一种端子结构，其具备相互连接的阳端子及阴端子。阳端子具有沿着前后方向延伸的突片。阴端子具有可嵌合突片的截面为矩形的嵌合部。在嵌合部的内部突出的设置有能弹性变形的舌片。突片***到嵌合部的内部，弹性地夹持在舌片与嵌合部的顶面之间而与阴端子电连接。

专利文献1：日本特开2001-357922号公报
发明内容
发明要解决的技术问题
但是，当端子为小型时，舌片也相对地变小，弹力减退，有相对于突片不能得到较高的接触负荷(接触压力)的担心。另外，在小型端子的情况下，当突片的轴心相对于嵌合部哪怕稍微错位时，该错位的影响也变得显著，也有不能稳定地确定突片和舌片的接触位置的问题。
本发明是基于如上述的情况完成的，其目的是提供能确保高的接触负荷、且不易受到突片错位的影响的端子结构。
用于解决技术问题的技术方案
本发明是具备相互连接的阳端子及阴端子的端子结构，其特征在于，所述阳端子具有在前后方向延伸的突片，所述阴端子具有：平板状的基部，其在前后方向延伸；接触片部，其从所述基部的一侧缘立起，进一步卷弯，前端朝向所述基部配置；以及开放部，其在与所述接触片部的立起部分相对侧使所述接触片部的前端与所述基部开放，所述突片在所述阳端子及阴端子连接时弹性地夹持在所述基部与所述接触片部之间，具有沿着前后方向与所述接触片部的前端缘接触的部分，并且具有从所述开放部向侧旁突出的部分。
发明效果
因为在阳端子及阴端子连接时突片弹性地夹持在基部与接触片部之间，具有沿着前后方向与接触片部的前端缘接触的部分，所以即使是小型端子，也能确保高接触负荷。另外，因为突片具有从开放部向侧旁突出的部分，所以实质上不需要两端子间的居中，能设为不易受到突片错位的影响的结构。

具体实施方式
以下表示本发明的优选实施方式。
可以在所述突片的、沿着前后方向与所述接触片部的前端缘的接触的部分设置有台阶状的止挡面，所述止挡面在所述突片从所述开放部拔出的方向与所述接触片部接触。据此，在振动时等能限制突片向从开放部拔出的方向错位，并能稳定地确定两端子的接触位置。
<实施例1>
以下，利用图1～图3说明实施例1。本实施例1的端子结构具备相互连接的阳端子10及阴端子60。阳端子10配置于未图示的阳壳体的内部，同样，阴端子60配置于未图示的阴壳体的内部。通过两壳体相互嵌合，从而阳端子10及阴端子60相互电连接。特别是在本实施例1的情况下，阳端子10及阴端子60由极小尺寸构成。
阳端子10为导电金属制，如图2所示，具有在前后方向细长地延伸的方形截面且实心的突片11。突片11的上下两面除了上表面的一部分(后述的容纳部12)之外沿着左右方向配置，突片11的左右两面沿着上下方向配置。该突片11成为上下两面的左右尺寸比左右两面的上下尺寸长的形状。
在突片11的上表面中的从左右方向中央向一侧(图3的右侧)靠近的位置凹设有容纳部12，容纳部12容纳阴端子60的后述的接触片部67的前端。容纳部12具有沿着左右方向的底面13和沿着上下方向的一对侧面，形成浅底的方形凹状截面，成为在突片11上遍及前后方向的全长延伸的形状。两侧面中图3的左侧的侧面构成为止挡面14，止挡面14限制突片11相对于阴端子60向图示右方错位。
阴端子60是在将导电性的金属板冲裁为规定形状后进行卷弯加工而形成的，整体上成为在前后方向细长的形状。如图1所示，阴端子60在前部具有与阳端子10的突片11连接的连接部61，在后部具有与电线90的末端部连接的线筒部62及绝缘筒片部63。线筒部62与在电线90的末端部露出的芯线部91压接而电连接。绝缘筒片部63位于线筒部62的后方，与电线90的末端部的包覆部92压接而机械地连接。
连接部61成为以阴端子60整体的前后长度的一半或者稍微超出一半的长度细长地延伸的形状。如图3所示，连接部61具有：平板状的基部64；立起部65，其从基部64的沿着前后方向的一侧缘立起；以及弧状部66，其从立起部65的上端部分卷弯成半圆弧状，并以前端从上方与基部64的另一侧缘侧对置的方式垂下。基部64、立起部65以及弧状部66在周向上连续地形成。
如图1所示，基部64从线筒部62及绝缘筒片部63的底板部分连续地配置，立起部65从线筒部62及绝缘筒片部63的侧板部分连续地配置。如图3所示，立起部65设为相对于基部64的一侧缘大致呈直角地立起的形状。立起部65和弧状部66构成为接触片部67，接触片部67能以基部64的一侧缘为支点挠曲变形。在弧状部66的前端前缘设置有锥状的倒角部68。
另外，连接部61中、与立起部65相对侧的弧状部66的前端与基部64的上表面之间的位置作为开放部69向侧旁开放。弧状部66的前端及基部64的上表面除了倒角部68之外在前后方向上大致平行地配置，开放部69在前后方向上以大致相同高度连续，连接部61的前后两端也开放。开放部69的高度尺寸(上下尺寸)设为在接触片部67处于自然状态时比突片11的下表面与容纳部12的底面13之间的高度尺寸稍小。
接着，对阳端子10及阴端子60的连接方法及连接结构进行说明。
在阳端子10及阴端子60连接之前，在阴端子60的线筒部62及绝缘筒片部63上连接电线90，将多个阴端子60安装于阴壳体，并且将多个阳端子10安装于阳壳体。
接着，两壳体相互嵌合。在两壳体的嵌合过程中，阳端子10的突片11的容纳部12在阴端子60的倒角部68上滑动，伴随于此，接触片部67稍微挠曲变形。在该状态下，阴端子60的弧状部66的前端***到容纳部12并与底面13滑动接触，沿着容纳部12引导两端子10、60的连接动作。另外，突片11中比容纳部12靠图示右侧的端部成为从开放部69向侧旁伸出的状态。
在两壳体正式嵌合时，如图2所示，阴端子60的弧状部66的前端成为沿着前后方向与容纳部12的底面13较长地抵接的状态，两端子10、60以高接触负荷电连接。另外，突片11的端部从开放部69向侧旁突出，因此突片11和连接部61的相互的轴心向宽度方向偏心。在此，允许两端子10、60在弧状部66的前端和容纳部12的两侧面的间隙范围向宽度方向的错位。因此，在本实施例1的情况下，不必使两端子10、60的轴心严密地对齐，能适当使用于容易受到错位影响的小型端子。
但是，当由于周边的振动等(例如发动机振动等)使突片11将要向从连接部61的开放部69拔出的方向(图3的右方)错位时，则容纳部12的止挡面14与弧状部66的前端侧的内表面抵接，可限制突片11的错位。因此，可稳定地维持两端子10、60的接触状态。
<实施例2>
图4表示本发明的实施例2。在实施例2的情况下，阳端子10的容纳部12A的形状与实施例1的阳端子10的容纳部12的形状不同，除此之外与实施例1同样，对与实施例1相同或者相当的部位标注相同附图标记，省略重复的说明。
容纳部12A在突片11的上表面的图4右侧的角部呈切口状凹设。该容纳部12A具有沿着左右方向的底面13A和沿着上下方向的止挡面14A，形成L字状截面，容纳部12A成为与止挡面14A相对侧开放的形状。
在实施例2的情况下，容纳部12A的底面13A比实施例1的容纳部12的底面13在宽度方向上增大，因此弧状部66的前端可靠地容纳于容纳部12A，并且能容易吸收突片11与连接部61之间的错位。
此外，在弧状部66的前端与容纳部12A的底面13A抵接的状态下，利用止挡面14A限制突片11向从开放部69拔出的方向错位，在这方面与实施例1同样。
<其它实施例>
以下，简单地说明其它实施例。
(1)突片也可以不具有容纳部，而是上表面由在宽度方向上没有凹凸地相连的平坦面构成。
(2)接触片部也可以不具有立起部，而从基部的一侧缘仅由圆弧状的弧状部构成。
