Description

电连接器
技术领域
本发明涉及电连接器领域。
背景技术
随着笔记本、平板电脑、手机等消费性电子产品小型轻薄化的发展趋势,对其零部件的设计和制造工艺要求越来越高,由于产品日渐轻薄化,其内部的空间也变得非常狭小,这就要求产品内部必须要采用密集化布局,各个电子零件的体积也越来越小,越来越轻薄化。对于一些传输高频信号的连接器来说,轻薄小巧的体积使得连接器内的端子之间的排列必须更加密集紧凑,而这势必会对信号的传输带来一定的影响。为了屏蔽端子之间的信号干扰,对于很多连接器来说,都会额外设置屏蔽元件,例如,在USB连接器中,上下排端子之间通常会埋设一个金属隔离板,通过金属隔离板来隔离上下排信号的干扰。但是,随着对信号品质的要求越来越高,现有的金属隔离板仅能提供上下排信号之间的隔离,而无法提供更多的隔离屏蔽的效果,难以满足日益提高的产品电性能要求。
发明内容
本发明所解决的技术问题在于提供一种电连接器组合,以改善现有技术中隔离板屏蔽功能不足的问题。
为解决上述技术问题,本发明采用如下技术方案:一种电连接器,包括绝缘本体、收容于绝缘本体内的端子组及隔离板,所述端子组包括若干上排端子及若干下排端子,所述隔离板介于所述上排端子和下排端子之间,所述隔离板设有一体连接的一对上接地臂及一对下接地臂,所述上接地臂与所述若干上排端子位于同一平面内且位于所述若干上排端子的两侧,所述下接地臂与所述若干下排端子位于同一平面内且位于所述若干下排端子的两侧。

进一步地,所述基板在上接地臂的正下方位置处设有狭槽,所述上接地臂与下接地臂沿竖直方向上一一对应设置,所述狭槽位于上接地臂和下接地臂之间。
进一步地,所述上接地臂通过撕破成型的方式形成于所述基板正表面的两侧。
进一步地,所述下接地臂位于所述基板的下方且自后向前呈长条形延伸,所述下接地臂后端通过一U型弯折臂与所述基板一体连接,其前端为自由末端。
进一步地,所述上接地臂和下接地臂在竖直方向上至少部分投影重叠。
进一步地,所述绝缘本体设有对接舌板,所述对接舌板设有顶表面和底表面,所述若干上排端子和上接地臂设于所述顶表面上,所述若干下排端子和下接地臂设于所述底表面上。
进一步地,所述隔离板还设有自基板后端延伸出的第一安装脚、第二安装脚及第三安装脚,所述第一安装脚、第二安装脚自基板的后端边缘延伸出且沿前、后方向分布,所述第三安装脚自基板的两侧边缘向外延伸出。

具体实施方式
请参阅图1至图7所示,本发明提供一种电连接器,其包括绝缘本体10、收容于绝缘本体10内的端子组20和隔离板30以及包覆于绝缘本体10表面的壳体40,其中,所述端子组20和隔离板30固定在绝缘本体10内,用于实现信号的稳定传输,所述壳体40则用于屏蔽外部干扰信号同时对绝缘本体10起到一定的保护作用。以下详细描述每个部件的具体结构和功能。
如图1和图2所示,所述绝缘本体10设有基部11及自基部11向前延伸出的对接舌板12,所述基部11的两侧设有顶面13及位于顶面13两侧的一对弧形壁面14,所述顶面13上设有若干与壳体40卡扣定位的凹槽15,所述弧形壁面14则用于与所述壳体40贴合安装。另外,所述顶面13的后侧设有向上凸伸的止挡部16,用于从后方抵挡住壳体40,实现前后方向上的限位。所述对接舌板12设有顶表面120和底表面121,用于承载所述端子组20,而且,所述对接舌板12的两侧边设有向内凹陷的凹缺部17。
如图2及图6所示,所述端子组20包括若干上排端子210及若干下排端子220,所述上排端子210和下排端子220数量相同且彼此上下一一对应,且两者分别设置在对接舌板12的顶表面120和底表面121,其中,所述上排端子210设有暴露于对接舌板12顶表面120的上接触臂211及自上接触臂211后端延伸出的L型的上安装臂212,所述上接触臂211由后向前延伸,且上接触臂211的前端设有一上埋入部213,用于埋入于所述对接舌板12内部。所述下排端子220设有暴露于对接舌板12底表面121的下接触臂221以及自下接触臂221的后端延伸出的下安装臂222,所述下接触臂221自后向前延伸,且下接触臂221的前端设有一下埋入部223。
值得一提的是,本发明最佳实施例中,所述上接触臂211设有上主臂214及自上主臂214的前端向前延伸出的上偏移臂215,所述上偏移臂215与所述上主臂214为一体结构,但所述上偏移臂215在水平面内朝所述上主臂214的一侧偏离设置;所述下接触臂221设有下主臂224及自下主臂224的前端向前延伸出的下偏移臂225,所述下偏移臂225与所述下主臂224为一体结构,且所述下偏移臂225在水平面内朝向所述下主臂224的一侧偏离设置。需要说明的是,所述上主臂214和下主臂224分别固定在对接舌板12的上、下两侧,且两者在竖直方向上错开设置,使得其投影并不重叠,而所述下偏移臂225、上偏移臂215则分别自上主臂214和下主臂224的前端朝相反的方向偏离设置,因而在竖直方向上,所述上偏移臂215和下偏移臂225的投影发生重叠,也就是说,对于两个上、下对应的上排端子210和下排端子220来说,两者的上主臂214、下主臂224在竖直方向上呈错开设置,投影不重叠,而两者的上偏移臂215、下偏移臂225则分别自上主臂214、下主臂224的前端位置向前延伸并呈相互靠拢设置,从而实现在竖直方向上两者的投影重叠。
另外,所述上埋入部213自所述上接触臂211的前端向下折弯并埋入所述对接舌板12内,所述下埋入部223自所述下接触臂221的前端向上折弯并埋入所述对接舌板12内,从而实现端子的固定,需要注意的是,在本发明较佳实施例中,所述上埋入部213设有偏向左侧的上限位臂216,所述下埋入部223设有偏向右侧的下限位臂226,因此,所述上排端子210的所述上限位臂216和下排端子220的下限位臂在竖直方向上呈现错开设置,如图7所示。
可见,对于上下相互对应的两个上排端子210和下排端子220来说,两者在竖直方向上存在部分位置重叠、部分位置错开的分布,由于所述上偏移臂215、下偏移臂225是作为上排端子210和下排端子220的电性接触部位,因此两者在竖直方向上重叠的设置更有利于信号的传输,而所述上安装臂212、下安装臂222是作为上排端子210和下排端子220的安装部位,其向后延伸出绝缘本体10外,用于焊接在电路板(未图示)上,因此,两者在竖直方向上错开的设置更有利于安装操作。
如图4及图5所示,所述隔离板30埋设于所述对接舌板12内,且介于上排端子210和下排端子220之间,起到隔离的作用,所述隔离板30为金属材质,其由金属板材一体冲压并折弯而成,所述隔离板30设有基板31及自基板31后端延伸出的第一安装脚32、第二安装脚33及第三安装脚34,所述基板31设有朝上设置的正表面35及朝向设置的背表面36。所述基板31设有一对位于所述正表面35两侧的上接地臂37及自自正表面35两侧边缘向下弯折延伸而成的下接地臂38,且基板31的前端边缘设有一对向后凹陷形成的缺口310,而基板31上还设有竖直方向上贯通所述正表面35和背表面36的狭长型开孔311,其中,所述上接地臂37向上凸起于所述正表面35,其呈长条形且沿所述基板31的两侧边缘由后向前延伸而成,而所述下接地臂38位于所述基板31的下方,其通过一U型弯折臂39与所述基板31一体连接,且所述下接地臂38呈长条形,其自后向前延伸而成。所述第一安装脚32、第二安装脚33自基板31的后端边缘延伸出且沿前、后方向分布,其分别位于上排端子210排列的两端以及下排端子220排列的两端,所述第三安装脚34位于所述第一安装脚32和第二安装脚33的外侧,其直接插置于电路板内实现电性连接,且第三安装脚34在前后方向上介于第一安装脚32和第二安装脚33之间。
值得一提的是,所述上接地臂37和下接地臂38分别位于基板31的正、反两侧,且在竖直方向上至少部分投影重叠;而且,所述上接地臂37是通过撕破成型的方式形成在所述基板31上,因此,上接地臂37的前、后两端均与所述基板31一体连接,且所述基板31在上接地臂37的正下方位置处设有由撕破成型而留下的狭槽312,所述两个上接地臂37相互平行延伸;而所述下接地臂38的前端为自由末端,其并未与所述基板31一体连接,而是采用搭接方式连接至基板31的背表面36,所述下接地臂38的后端则与所述U型弯折臂39一体连接。所述上接地臂37位于所述上排端子210排列的首末两侧,且与上排端子210平行设置,所述下接地臂38位于所述下排端子220排列的首末两侧,且与下排端子220平行设置。这样一来,所述隔离板30不但具有了隔离上下排端子220的作用,而且还增加了暴露于对接舌板12顶表面120和底表面121上的上接地臂37、下接地臂38,充当了上排端子210排列和下排端子220排列的接地元件,能有效改善信号传输,而且上接地臂37和下接地臂38与基板31为一体式的结构,保证了接地连接的稳定性,可满足高频传输的要求。
综上所述,本发明通过改良隔离板的结构,使其增加延伸入端子排列中的上、下接地臂,充当接地元件,更好的保证端子的信号传输。
以上所述,仅是本发明的最佳实施例而已,并非对本发明作任何形式上的限制,任何熟悉本领域的技术人员,在不脱离本发明技术方案范围情况下,利用上述揭示的方法内容对本发明技术方案做出许多可能的变动和修饰,均属于权利要求书保护的范围。
