Description

一种多极基板电连接器 技术领域
本发明涉及一种表面贴装连接器，尤其涉及一种多极基板电连接器。
 背景技术
目前，表面贴装技术（Surface Mounted Technology，简称SMT），是电子组装行业里最流行的一种技术和工艺。它是一种将无引脚或短引线表面组装元器件（简称SMC/SMD，中文称片状元器件）安装在印制电路板（Printed Circuit Board，简称PCB)的表面或其它基板的表面上，通过再流焊或浸焊等方法加以焊接组装的电路装连技术。随着SMT技术的推广普及，表面贴装连接器的应用也越来越广泛，各种类型的PCB都有相应的表面贴装连接器出现，其中，应用最广泛的板对板（Board to Board，简称：BTB）连接器凭借体积小、优越的传输性能、低差损，低泄漏、高隔离屏蔽等优势，能够大规模应用于5G产品。
现有的BTB连接器，一般由公头，母座配合组成。公头由公头绝缘本体，固定于公头绝缘本体上的至少两列固定端子及公头金属外壳组成；母座由母座绝缘本体，固定于母座绝缘本体上的至少两列弹性端子及母座金属外壳组成。当公头与母座之间进行配合时，固定端子与弹性端子之间实现电连接，公头金属外壳与母座金属外壳互相接触实现了一定的屏蔽作用。然而，BTB连接器在传输多路射频信号时，固定端子之间、弹性端子之间及固定端子与弹性端子之间均会产生干扰，使得BTB连接器的隔离度性能较差。
因此，有必要对上述BTB连接器的结构进行改进。

当公头与母座插接配合时，由于公头内设置了用于接地的第一隔离板，母座内设置了用于接地的第二隔离板，第一隔离板与第二隔离板有效电接触，所以第一连接端子和第二连接端子均被第一隔离板及第二隔离板电接触后形成的隔离结构隔开，第一连接端子及第二连接端子内的射频信号耦合至中间的第一隔离板及第二隔离板时，可有效地将电流引入公头和母座的接地基板，从而减少了信号干扰，提升了连接器的隔离度性能。另外，当公头与母座插接配合时，两第一屏蔽壳体与第二屏蔽壳体电接触，还起到了屏蔽作用。

 本发明的实施方式
下面结合附图和实施方式对本发明作进一步说明。
请参阅图1至图6，图1为本发明提供的多极基板电连接器的结构示意图，图2为本发明提供的多极基板电连接器结构的分解示意图，图3为本发明提供的公头的结构示意图，图4为本发明提供的公头结构的分解示意图，图5为本发明提供的母座的结构示意图，图6为本发明提供的母座结构的分解示意图。
如图1至图6所示，本发明第一实施例提供的多极基板电连接器，包括互相插接配合的公头1和母座2，所述公头1包括第一绝缘本体11，固定于所述第一绝缘本体11的第一屏蔽壳体12以及固定于所述第一绝缘本体11的至少两列第一连接端子13；所述母座2包括第二绝缘本体21，固定于所述第二绝缘本体21的第二屏蔽壳体22以及固定于所述第二绝缘本体21的至少两列第二连接端子23；
且，所述公头1还包括位于至少两列所述第一连接端子13之间且设置于所述第一绝缘本体11上用于接地的第一隔离板14，所述母座2还包括位于至少两列所述第二连接端子23之间且设置于所述第二绝缘本体21上用于接地的第二隔离板24，所述公头1与所述母座2插接配合时，所述第一屏蔽壳体12与所述第二屏蔽壳体22电接触，所述第一连接端子13与所述第二连接端子23一一对应电接触，所述第一隔离板14与所述第二隔离板24电接触。
需要说明的是，每列所述第一连接端子13包括至少两个间隔设置的第一信号端子131和第一接地端子132，每列所述第二连接端子23包括至少两个间隔设置的第二信号端子231和第二接地端子232。
传统的BTB连接器中，公头与母座进行插接后，由于分别位于公头和母座相对两侧的连接端子之间没有任何隔离结构，所以导致分别位于公头和母座同侧或异侧的连接端子之间会产生较大的干扰。
而本实施例提供的多极基板电连接器中，当公头1与母座2插接配合时，由于公头1内设置了用于接地的第一隔离板14，母座2内设置了用于接地的第二隔离板24，第一隔离板14与第二隔离板24有效电接触，所以第一连接端子13和第二连接端子23均被第一隔离板14及第二隔离板24电接触后形成的隔离结构隔开，第一连接端子13及第二连接端子23内的射频信号耦合至中间的第一隔离板14及第二隔离板24时，可有效地将电流引入公头1和母座2的接地基板，从而减少了信号干扰，提升了连接器的隔离度性能。另外，当公头1与母座2插接配合时，第一屏蔽壳体12与第二屏蔽壳体22电接触，还起到了屏蔽作用。
请参阅图4、图6以及图7至图13，图4为本发明提供的公头结构的分解示意图，图6为本发明提供的母座结构的分解示意图，图7为本发明提供的第一屏蔽壳体的结构示意图，图8为本发明提供的第二屏蔽壳体的结构示意图，图9为本发明提供的第一隔离板与第二隔离板电接触时的状态示意图，图10为本发明提供的第一隔离板、第二隔离板、第一屏蔽壳体和第二屏蔽壳体的组合状态示意图，图11为本发明提供的多极基板电连接器沿图1中A-A方向的剖视图，图12为本发明提供的多极基板电连接器同侧不同射频通道之间的隔离度性能与传统BTB连接器的对比图，图13为本发明提供的多极基板电连接器异侧射频通道之间的隔离度性能与传统BTB连接器的对比图。
