请参照图1至图5，本发明的实施例二为：射频连接器组件，包括射频线1、连接器公端2、连接器母端3和线路板4，连接器公端2包括公端基体5，连接器母端3包括母端基体6，连接器公端2还包括罩设公端基体5的屏蔽罩7，屏蔽罩7与射频线1的地导通；连接器母端3还包括屏蔽框8，母端基体6设于屏蔽框8内，屏蔽框8为全周无缝隙结构，容易理解的，全周无缝隙结构的屏蔽框8可由拉伸工艺、冷锻工艺、粉末冶金等工艺制成，屏蔽框8的底端与线路板4接触并形成呈环状的接触区域。优选的，所述接触区域为所述屏蔽框8与所述线路板4的接地导通区域9。
当所述连接器公端2与所述连接器母端3连接后，作为优选，所述屏蔽罩7与所述屏蔽框8导通，可选的，所述屏蔽罩7与所述屏蔽框8卡扣连接并实现导通。
进一步的，所述屏蔽框8的底端具有朝外延伸的护边10，所述屏蔽罩7的底端抵触所述护边10的顶面。
具体的，所述屏蔽罩7包括顶板11，所述顶板11的边沿设有周板12，所述周板12为具有进线口13的全周封闭式结构。屏蔽罩7能够对除了进线口13以外的其他区域进行多方位屏蔽，能够有效地防止信号泄漏及信号干扰，利于提高射频连接器组件的屏蔽效果。
本实施例为多信号通路信号传输组件，具体的，所述公端基体5上设有多个公端信号端子14，相邻的两个所述公端信号端子14通过与所述屏蔽罩7导通的隔离片16隔离；所述连接器母端3中，母端基体6的数量和屏蔽框8的数量分别为多个且母端基体6与屏蔽框8一一对应设置，每个所述母端基体6上均设有一个与所述公端信号端子14相配合的母端信号端子15，相邻的两个所述屏蔽框8固定相连，所述隔离片16插入相邻的两个所述屏蔽框8之间，以使各信号端子之间不互相产生信号干扰，容易理解的，此处所说的各信号端子之间指代的是公端信号端子与公端信号端子之间、母端信号端子与母端信号端子之间以及公端信号端子和非与之配合的母端信号端子之间。优选的，相邻的两个所述屏蔽框8导通固定。
本实施例中，所述隔离片16固定在所述公端基体5上，优选的，所述隔离片16与所述公端基体5通过嵌件注塑成型为一体式结构，如此可便于加工。
为进一步提高射频连接器组件的屏蔽效果，连接器公端2与连接器母端3插接配合后，所述隔离片16分别与其两侧的所述屏蔽框8接触导通。
为让隔离片16与屏蔽罩7能够稳定导通，对相邻的两个公端信号端子14实现良好隔离，所述隔离片16的顶面的各区域均与所述顶板11接触导通。
本实施例中，为便于公端基体5的成型，降低连接器公端2的加工难度，所述隔离片16的前端面与所述周板12之间具有间隙17。但为进一步提高射频连接器组件的屏蔽性能，也可以选择让所述隔离片16的前端面的至少一部分抵触导通所述周板12。
综上所述，本发明提供的射频连接器组件能够让相配合的每组公/母端信号端子均处于不同的全屏蔽的工作环境中，有效地提高了射频连接器组件的屏蔽性能，使得射频连接器组件拥有优异的电学性能。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等同变换，或直接或间接运用在相关的技术领域，均同理包括在本发明的专利保护范围内。
