Description

一种导电接触件及电连接器及电连接器组件 技术领域
本发明涉及导电连接，尤其涉及一种导电接触件及电连接器及电连接器组件。
背景技术
差分连接器往往应用于高速、高质量传输信号的场合，而差分连接器内部多采用片式接触件实现导电接触。如申请公布号为CN104167620A、申请公布日为2014.11.26的中国发明专利就公开了一种弯式接触件及插孔模块和电连接器。这种电连接器的弯式接触件具有前后延伸的接触件基体，接触件基体的前端为插接端，插接端包括插接部以及位于插接部后方的安装部，插接部的前端头处具有向上弯折的翻边，翻边弯折处的下侧面形成用于与适配接触件接触的前接触部，翻边的前侧弯折面为用于在于适配接触件插接时进行导向的导向斜面；插接部和安装部之间还具有向下凹陷的凹部，凹部的下侧形成用于与适配接触件接触的后接触部，插接部从其与凹部的连接处自后向前向下倾斜，该段为连接前、后接触部的连接段。这种弯式接触件的前、后接触部位于同一水平面上且在与适配接触件插接配合时均与适配接触件的上侧面接触，在实际使用过程中受加工精度、装配精度以及插接精度的影响，前、后两个接触部很容易出现只有其中一个与适配接触件导电接触的情况，而且在使用一段时间之后，前接触部长时间受插接作用力的影响往往会向上翘起而不能与适配接触件良好接触，这样不但严重影响导电传输，而且还使得接触点一侧具有较长的悬伸端，形成短桩辐射效应，增大了插接损耗。
发明内容
本发明的目的在于提供一种前后接触部能够稳定接触的导电接触件，用以解决现有的弯式接触件的前、后两个接触部不能同时稳定接触的问题；本发明的目的还在于提供一种使用该接触件的连接器；本发明的目的还在于提供一种电连接器组件。
本发明的接触件，包括前后延伸的接触件基体，所述接触件基体的下表面具 有位于前端的前接触部以及位于前接触部后侧的后接触部，所述前接触部相对于后接触部向下偏移；所述接触件基体上在前接触部的前侧还设有用于在插接过程中与适配接触件的前端顶推配合，以使适配接触件将前接触部向上顶推而与后接触部接触的导向斜面。
所述接触件基体在后接触部的后侧设有前后水平延伸的安装段，所述安装段位于后接触部的上方。

所述接触件为弹性件。
本发明的连接器，包括接触件，所述接触件包括前后延伸的接触件基体，所述接触件基体的下表面具有位于前端的前接触部以及位于前接触部后侧的后接触部，所述前接触部相对于后接触部向下偏移；所述接触件基体上在前接触部的前侧还设有用于在插接过程中与适配接触件的前端顶推配合，以使适配接触件将前接触部向上顶推而与后接触部接触的导向斜面。
所述接触件基体在后接触部的后侧设有前后水平延伸的安装段，所述安装段位于后接触部的上方。
所述安装段和后接触部通过从后向前逐渐向下倾斜的过渡段连接，所述后接触部与前接触部通过从后向前逐渐向下倾斜的连接段连接。
所述接触件基体上设置有向下凹的凹部，所述后接触部为凹部的下侧面。
接触件基体的前端设有向上翻折的翻边，所述前接触部为翻边弯折位置的下侧面，所述导向斜面为翻边的位于前接触部前侧的下侧面。
前接触部相对于后接触部向下偏移的尺寸范围为0.02mm～2mm。
所述接触件为弹性件。
本发明的连接器组件，包括公端接触件和母端接触件，所述公端接触件前后水平延伸，所述母端接触件包括前后延伸的母端接触件基体，所述母端接触件基 体的下表面具有位于前端的前接触部以及位于前接触部后侧的后接触部，所述前接触部相对于后接触部向下偏移；所述母端接触件基体上在前接触部的前侧还设有用于在插接过程中与公端接触件的前端顶推配合，以使公端接触件将前接触部向上顶推而与后接触部接触的导向斜面。
所述母端接触件基体在后接触部的后侧设有前后水平延伸的安装段，所述安装段位于后接触部的上方。
所述安装段和后接触部通过从后向前逐渐向下倾斜的过渡段连接，所述后接触部与前接触部通过从后向前逐渐向下倾斜的连接段连接。
母端接触件基体上设置有向下凹的凹部，所述后接触部为凹部的下侧面。
母端接触件基体的前端设有向上翻折的翻边，所述前接触部为翻边弯折位置的下侧面，所述导向斜面为翻边的位于前接触部前侧的下侧面。

所述母端接触件为弹性件，所述公端接触件为前后水平延伸的刚性件。
本发明的连接器组件的母端接触件的前接触部相对于后接触部向下偏移，在母端接触件与公端接触件相互插接时，公端接触件与母端接触件的后接触部位于同一水平位置，公端接触件与母端接触件的前端导向斜面顶推配合而将母端接触件的前接触部向上顶推，此时公端接触件与前接触部接触并使其发生向上的弹性变形，公端接触件继续相对于母端接触件向后移动，进而与母端接触件的后接触部接触。由于前接触部发生向上的弹性变形，其对公端接触件有向下的弹性作用力，能够保证前接触部与公端接触件稳定接触，公端接触件与母端接触件的后接触部位于同一水平位置，也能够实现公端接触件与后接触部的良好接触，这样就保证公端接触件和母端接触件的良好导电接触。
进一步地，连接安装部与后接触部的过渡段以及连接后接触部与前接触部的连接段均为从后向前逐渐向下的倾斜段，简化了接触件的结构，使得接触件在上下方向占用的空间较小。
进一步地，前接触部相对于后接触部的向下偏移尺寸在0.02mm～2mm之间，控制偏移尺寸在合理的范围内，保证前接触部对公端接触件的弹性作用力在合适的范围内，避免出现前接触件对公端接触件的弹性作用力较大而导致公端接触件受损或者前接触件对公端接触件的弹性作用力较小而不能稳定接触的问题。
进一步地，公端接触件为刚性件，母端接触件为弹性件，这样避免了公端接触件受前接触部的弹性作用力而向下变形不能与后接触部良好接触。
附图说明
图1为本发明的接触件的实施例一的结构示意图；
图2为本发明的接触件的实施例一在与适配接触件插接配合的状态图。
具体实施方式
下面结合附图对本发明的实施方式作进一步说明。
本发明的连接器组件的具体实施例，包括公端连接器和母端连接器，公端连接器内设有公端接触件，母端连接器内设有母端接触件。为了便于说明，定义公端接触件的朝向母端接触件的一端为前端，母端接触件的朝向公端接触件的一端为前端。
如图1至图2所示，母端接触件包括前后延伸的接触件基体1，接触件基体1为能够在上下方向发生弹性变形的弹性件。接触件基体1的前端具有前接触部11，接触件基体1上在前接触部11的后侧具有后接触部13。前接触部11和后接触部13通过之间的连接段12连接，连接段12从后向前逐渐向下倾斜。前接触部11是通过在接触件基体1的前端设有向上翻折的翻边10形成的，具体地，前接触部11为翻边10弯折位置的下侧面，翻边10的位于前接触部11的前方下侧面构成用于与适配接触件2顶推配合的导向斜面100。后接触部13是通过在接触件基体1上设置向下凹的凹部14形成的，具体地，后接触部13为凹部14的下侧面。
其中，前接触部11相对于后接触部13向下偏移一定尺寸C，本实施例中，尺寸C的范围为0.02mm～2mm。当然，在其他实施例中，根据接触件的材质和弹性大小可以改变偏移尺寸C的大小。
接触件基体1在后接触部13的后侧还设有用于安装在连接器上的安装段，本实施例中，安装段前后水平延伸，当然，在其他实施方式中，安装段可以采用其他结构或形状。
公端接触件2为前后水平延伸的刚性件，其在上下方向上基本不发生变形，公端接触件2与母端接触件的后接触部13位于同一水平位置。公端接触件2在与母端接触件插接时，其前端首先与母端接触件的前端翻边10的下侧导向斜面 100接触，继续插接时将母端接触件的翻边10向上顶推使其发生向上的弹性变形，进而与前接触部11接触；在后续的插接过程中，前接触部11与公端接触件2的上侧面始终保持接触并发生相对滑动，插接到位时，公端接触件2与母端接触件的后接触部13接触。
由于母端接触件为弹性件，在与公端接触件2插接时前接触部11受到公端接触件2带来的插接作用力向上发生弹性变形，因此，母端接触件的前接触部11在弹性力的作用下能够保证与公端接触件的稳定接触，而母端接触件的后接触部由于与公端接触件在同一水平面上，也能够与公端接触件实现连接接触，这样就避免了前、后接触部中仅有一个与公端接触件接触而造成短桩效应，减小了插接损耗。由于前接触部向上发生变形的变形量为C，因此，前接触部和后接触部之间的偏移尺寸就决定了母端接触件发生弹性变形时的弹性作用力的大小，在设计时，根据公端接触件以及母端接触件的材质可以设置合理的偏移尺寸而使弹性作用力的大小较为合适。
此外，本实施例中公端接触件与母端接触件的后接触部位于同一水平面上，那么为了保证公端接触件能够与后接触部可靠接触，公端接触件最好不在上下方向发生变形，因此采用刚性件。在其他实施例中，如果在安装时公端接触件位于母端接触件的后接触部的偏上侧位置，那么公端接触件可以在插接过程中向下发生一定的变形，此时公端接触件可以具有一定的弹性。
本发明的连接器的实施例：其具体结构与上述连接器组件的实施例中的母端连接器的结构相同，此处不再赘述。
本发明的接触件的实施例：其具体结构与上述连接器组件的实施例中的母端接触件的结构相同，此处不再赘述。
