其中，第一基板11提供承载基体，第一绝缘件12设置于第一基板11的一侧。第一导电端子13、第一信号屏蔽件14以及第二信号屏蔽件15安装于第一绝缘件12，且第一信号屏蔽件14以及第二信号屏蔽件15与设置于第一基板11的接地电位电连接。
具体地，第一绝缘件12包括第一环形安装部121及与第一环形安装部121连接并位于第一环形安装部121内的限位部122，且第一环形安装部121和限位部122之间形成第一环形槽123。
在部分实施例中，第一信号屏蔽件14包括第一本体部141。第一本体部141呈环形套设于第一环形安装部121的外壁，且第一本体部141的一端固定于第一基板11，并与接地电位电连接。当第一连接组件10和第二连接组件20插接配合时，第一本体部141与第二连接组件20形成多点环形接触。
在部分实施例中，第一信号屏蔽件14还包括缺口屏蔽部142。在第一本体部141与第一基板11连接一端的相对两侧开设有避让第一导电端子13的第一缺口143，缺口屏蔽部142相对第一缺口143设置，并跨接于第一缺口并143与第一缺口143两端的第一本体部141和第一基板连接11连接，且与接地电位电连接，以在第一缺口143处形成有效电磁屏蔽，从而减少第一导电端子13所传输的电信号从第一缺口143外泄。
在部分实施例中，第一环形安装部121上设置有凸起1211，第一本体部141设置有卡槽1411，当第一信号屏蔽件14安装于第一环形安装部121时，凸起1211和卡槽1411卡合，以使第一信号屏蔽件14可以较为牢固安装于第一环形安装部121。
可以理解，凸起1211可以是一个或多个，可以设置于第一环形安装部121的一侧或相对两侧在此不做限定，只需凸起1211可以与设置于第一本体部141的卡槽1411形成卡合即可。
多个第一导电端子13呈两排布设于限位部122的相对两侧，并外露于第一环形槽123，每排第一导电端子13形成一组信号传输端子。
在限位部122靠近第二连接组件20一侧开设有开口1221，开口1221可以是一个或多个，可以根据需要设置。
第二信号屏蔽件15设置于两排第一导电端子13之间，并通过开口1221外露于限位部122，用于将两组第一导电端子13隔离，从而使得降低每排第一导电端子13所传输信号之间的彼此干扰。
具体地，第二信号屏蔽件15包括固定部151以及与固定部151连接的至少两个夹持部152，第二信号屏蔽件15通过固定部151固定于限位部122或第一基板11，夹持部152通过开口1221外露，以便于第二连接组件20形成配合。
请参阅图4-5，第二连接组件20包括第二基板21、第二绝缘件22、安装于第二绝缘件22的多个第二导电端子23、环设于第二导电端子23四周并用于与接地电位连接的第三信号屏蔽件24以及设置于多个第二导电端子23之间并用于与接地电位连接的第四信号屏蔽件25，第四信号屏蔽件25将多个第二导电端子23分隔成两组信号端子，该每组信号端子包括至少两个第二导电端子23。
其中，第二基板21提供承载基体，第二绝缘件22设置于第二基板21的一侧。第二导电端子23、第三信号屏蔽件24以及第四信号屏蔽件25安装于第二绝缘件22，第三信号屏蔽件24以及第四信号屏蔽件25与设置于第二基板21的接地电位电连接。
接地电位可以是在第一基板11和第二基板21中至少一者设置有导电件112，利用导电件112与信号地线连接以形成接地电位，如图6所示。
具体地，第二绝缘件22包括第二环形安装部221及设置于第二环形安装部221内的第三环形安装部222。第二环形安装部221和第三环形安装部222之间形成第二环形槽223。
第三信号屏蔽件24安装于第二环形安装部221。具体地，第三信号屏蔽件24包括第二本体部241、设置于第二本体部241的多个弹性接触件242以及设置于第二本体部241靠近第一连接组件10一侧的贴合件243。其中，第二本体部241自第二基板21向第一基板11延伸。
当第一连接组件10和第二连接组件20插接配合时，弹性接触件242弹性夹持第一本体部141，贴合件243与第一信号屏蔽件14环形周向贴合形成环形屏蔽。
也即，当第一连接组件10和第二连接组件20插接配合时，第一信号屏蔽件14和第三信号屏蔽件24配合以在第一导电端子13和第二导电端子23的四周形成环形屏蔽，同时在自第一基板11至第二基板21的方向上形成严密的屏蔽。
较佳地，多个弹性接触件242分别设置于第二本体部241的相对两侧或四周。
多个第二导电端子23呈两排分别布设于第三环形安装部222的相对两侧，并外露于第二环形槽223。每排第二导电端子23形成一组信号传输端子与对应的第一导电端子13进行信号传输。
第四信号屏蔽件25设置于两排第二导电端子23之间，且第四信号屏蔽件25设置有至少两个插接部251，以便于第二信号屏蔽件15配合。
如图6所示，当第一连接组件10和第二连接组件20插接配合时，第一环形安装部121插接到第二环形槽223内，第三环形安装部222插接到第一环形槽123内。
此时，第一导电端子13和对应的第二导电端子23接触，进行信号传输。
第三信号屏蔽件24的第二本体部241和第一信号屏蔽件14的缺口屏蔽部142形成多点接触，且设置于第二本体部241的弹性接触件242与第一本体部141形成多点接触，从而在第一导电端子13和第二导电端子23的四周形成有效信号屏蔽，避免外部信号对第一导电端子13和第二导电端子23所传输信号的干扰。
同时，设置于第一导电端子13之间的第二信号屏蔽件15和设置于第二导电端子23之间的第四信号屏蔽件25接触，从而将连接器1内部的第一导电端子13和第二信号屏蔽件15隔离为两个信号传输组，并降低每个信号传输组所传输的信号之间的互相干扰。
在部分实施例中，第一环形安装部121还设置有限位槽1212，较佳地，限位槽1212设置于第一环形安装部121的相对两侧。
第二环形安装部221和第三环形安装部222之间设置有与限位槽1212配合的限位块224。
在部分实施例中，第一信号屏蔽件14、第二信号屏蔽件15、第三信号屏蔽件24、第四信号屏蔽件25为金属信号屏蔽件。可以理解第一信号屏蔽件14、第二信号屏蔽件15、第三信号屏蔽件24、第四信号屏蔽件25可以不是金属信号屏蔽件，只需第一信号屏蔽件14、第二信号屏蔽件15、第三信号屏蔽件24、第四信号屏蔽件25可以导电即可。
与现有设计相比，本发明所提供的连接器包括可插接配合的第一连接组件和第二连接组件，通过在第一连接组件设置有第二信号屏蔽件，并将第二信号屏蔽件设置于多个第一导电端子之间，以将第一导电端子分隔成两组信号端子，同时在第一导电端子四周设置有环形结构的第一信号屏蔽件；通过在第二连接组件设置有第四信号屏蔽件，并将第四信号屏蔽件设置于多个第二导电端子之间，以将第二导电端子分隔成两组信号端子，同时在第二导电端子四周设置有环形结构的第三信号屏蔽件。
在第一连接组件和第二连接组件插接配合时，第一导电端子的两组信号端子与第二导电端子的两组信号端子接触实现电连接；第一信号屏蔽件与第三信号屏蔽件电连接以及第二信号屏蔽件与第四信号屏蔽件形成多点接触电连接。
利用第一信号屏蔽件与第三信号屏蔽件形成外部环形屏蔽，从而降低连接器内第一导电端子和第二导电端子信号泄露。
进一步，利用第二信号屏蔽件和第四信号屏蔽在连接器内部形成两组信号端子之间信号传输的有效屏蔽，从而形成了内外全方位高效屏蔽低泄漏，很好的解决了连接器的内部信号之间的相互干扰，以及信号泄露的问题。
以上所述的仅是发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离发明创造构思的前提下，还可以做出改进，但这些均属于发明的保护范围。
