Description

弹性接触件及使用该接触件的电连接器 技术领域
本发明涉及电连接器领域，特别是涉及到了一种弹性接触件及使用该接触件的电连接器。
背景技术
转接器是电连接器中较为常见的一种，按照接触方式的不同，其可分为插接式和端接式。其中端接式的转接器是通过接触件的相应端与适配连接器顶压接触而实现电连。
用于端接式转接器中的接触件多为弹性接触件，目前，常见的用于端接式转接器中的弹性接触件主要有以下三种：1、C型，见图1；2、空间V型，见图2；3、螺旋弹簧型，见图3。
以上三种弹性接触件中，C型和空间V型在工作受力时，发生弯折的弯折点单一，因此很容易因为疲劳而产生塑性变形，因此使用寿命较短；螺旋弹簧型对接触件的材料要求较高，常用的铜材料不能为其提供足够的弹性接触力，因此需要专门的材料，制造成本较高，另外，螺旋弹簧的回路电感较大，也不利于转接器性能的优化。
发明内容
本发明的目的在于提供一种可用于端接式转接器中的、对材料要求低并且使用寿命长的弹性接触件。
同时，本发明的目的还在于提供使用上述弹性接触件的电连接器。
为了解决上述问题，本发明的弹性接触件采用以下技术方案：弹性接触件，包括用于与相应连接器导电接触的两个接触部以及位于两接触部之间的连接部，所述两接触部均具有弧形部分并且它们各自的弧形部分的外侧面构成用于与相应连接器导电接触的顶压面，两弧形部分口对口设置并且一端通过所述连接部过渡连接，所述连接部上具有向内弯折而鼓起的内凸部。
所述两接触部各自构成U形。
所述接触部和连接部均是采用板材或料带制成。
连接部与接触部之间的过渡处形成弧形。
所述接触部形成U形，两接触部的一端通过所述连接部连接，另一端彼此交错重叠。
电连接器采用以下技术方案：电连接器，包括绝缘板，绝缘板上设有通透的安装孔，安装孔中固定装配有弹性接触件，弹性接触件包括用于与相应连接器导电接触的两个接触部以 及位于两接触部之间的连接部，所述两接触部均具有弧形部分并且它们各自的弧形部分的外侧面构成用于与相应连接器导电接触的顶压面，两弧形部分口对口设置并且一端通过所述连接部过渡连接，所述连接部上具有向内弯折而鼓起的内凸部。
所述两接触部各自构成U形。
所述接触部和连接部均是采用板材或料带制成。
连接部与接触部之间的过渡处形成弧形。
所述接触部形成U形，两接触部的一端通过所述连接部连接，另一端彼此交错重叠。
由于该弹性接触件的两接触部均具有弧形部分，并且它们各自的用于与相应连接器导电接触的顶压面是由弧形部分的外侧面构成，所述连接部上具有向内弯折而鼓起的内凸部。因此在使用的过程中受压时，其接触部的弧形部分以及所述内凸部均构成变形部位，由此可有助于变形时应力的分散，从而起到增长弹性接触件使用寿命的作用，由于仅仅是由简单的弧形等构成，因此该弹性接触件对材质也没有特殊要求。
附图说明
图1是C型弹性接触件的结构示意图；
图2是空间V型弹性接触件的结构示意图；
图3是螺旋弹簧型弹性接触件的结构示意图；
图4是弹性接触件的实施例的结构示意图；
图5是电连接器的实施例的结构示意图；
图6是电连接器的绝缘体与弹性接触件的配合示意图。
具体实施方式
弹性接触件的实施例，如图4所示，该弹性接触件包括用于与相应连接器导电接触的两个接触部11以及位于两接触部之间的连接部12。
两接触部11各自具有弧形部分，并且弧形部分的外侧面构成用于与相应连接器导电接触的顶压面，在本实施例中，接触部11的具体形状为U形，两个接触部之间扩对口设置，顶压面位于接触部所形成的U形的底部外侧，接触部11之间通过连接部12过渡连接。在本实施例中，连接部时与两接触部的相邻的一端连接，接触部与连接部的连接处形成了弧形，由此可避免应力集中，另外，连接部上具有弧形的内凸部，内凸部是通过弯折而成并且向内凸出。两连接部的一端通过连接部连接，它们的另一端彼此交错重叠，由此使得弹性接触件构成了类似于“O”形的结构。在本实施例中，所述接触部和连接部均是采用板材或料带制成。
在弹性接触件的其它实施例中，接触部和连接部还可以是采用棒料制成；接触部还可以呈C形。
电连接器的实施例，如图5-6所示，包括绝缘板21和弹性接触件22，绝缘板21上设置有安装孔，弹性接触件22固定装配在相应的安装孔中，在本实施例中，弹性接触件22的结构与上述弹性接触件的实施例的结构相同，此处不予赘述。
在电连接器的其它实施例中，接触件还可以采用上述弹性接触件的实施例与其它类型接触件混装使用的形式。
