请结合图1和图5，屏蔽框32的底端具有朝外延伸的护边321，护边321的存在能够增大环状的接触区域的宽度，从而提高连接器母端3的屏蔽性能。可选的，所述屏蔽罩22的底端抵触所述护边321的顶面。
如图3所示，具体的，所述屏蔽罩22包括顶板221，所述顶板221的边沿设有周板222，所述周板222为具有进线口的全周封闭式结构。
请结合图2和图5，可选的，所述屏蔽罩22与所述屏蔽框32通过所述凸包41扣接，所述凸包41对应区域的所述屏蔽罩22的内周壁或所述屏蔽框32的外周壁上设有与所述凸包41相配合的卡槽42。当所述连接器公端2与所述连接器母端3连接后，所述屏蔽罩22与所述屏蔽框32通过所述凸包41导通。
当射频连接器组件为单通路连接器时，所述公端基体21上设有一个公端信号端子51，所述母端基体31上设有一个与所述公端信号端子51相配合的母端信号端子52。但本实施例中，所述射频连接器组件为多通路连接器，详细的，请结合图2和图5，所述公端基体21上设有多个公端信号端子51；所述连接器母端3中，母端基体31的数量和屏蔽框32的数量分别为多个且母端基体31与屏蔽框32一一对应设置，每个所述母端基体31上均设有一个与所述公端信号端子51相配合的母端信号端子52，相邻的两个所述屏蔽框32固定相连，优选的，相邻的两个所述屏蔽框32导通固定。
优选的，所述屏蔽罩22上设有隔离片223，相邻的两个所述公端信号端子51通过与所述屏蔽罩22导通的隔离片223隔离，所述隔离片223插入相邻的两个所述屏蔽框32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51与公端信号端子51之间、母端信号端子52与母端信号端子52之间以及公端信号端子51和非与之配合的母端信号端子52之间。

为保证隔离片223的结构稳定性，本实施例中，所述隔离片223固定在所述公端基体21上，优选的，所述隔离片223与所述公端基体21通过嵌件注塑成型为一体式结构，如此可便于加工。为让隔离片223与屏蔽罩22能够稳定导通，对相邻的两个公端信号端子51实现良好隔离，所述隔离片223的顶面的各区域均与所述顶板221接触导通，可选的，所述隔离片223通过点焊工艺与所述顶板221连接。
如图2所示，所述隔离片223的前端面与所述周板222之间具有间隙，或者，所述隔离片223的前端面的至少一部分抵触导通所述周板222。
实施例二
请参照图6至图8，本发明的实施例二是在实施例一的基础上提出的另外一种技术方案，与实施例一的不同之处在于：实施例一的射频连接器组件是一种线对板射频连接器，而本实施的射频连接器组件是一种板对板连接器。也就是说，本申请的技术方案不仅适用于线对板射频连接器，还适用于板对板射频连接器。
本实施例中，射频连接器组件为一种六通路板对板射频连接器，其包括插接配合的连接器公端2和连接器母端3，连接器公端2包括公端基体21和罩设公端基体21的屏蔽罩22，连接器母端3包括母端基体31和罩设母端基体31的屏蔽框32，连接器公端2与连接器母端3插接后，屏蔽罩22笼罩屏蔽框32。
详细的，屏蔽罩22的内周壁具有围绕屏蔽框32设置的多个凸包41，相邻的两个凸包41之间的间距小于或等于射频连接器组件工作频段的四分之一波长。当然，所述凸包41设于屏蔽框32的外周壁上也是可行的。
综上所述，本发明提供的射频连接器组件，能够将X/Y/Z轴各方向之信号阻隔在连接器内部，避免辐射出去造成信号泄露，同时，也能够阻止外界信号进入连接器内部导致信号干扰，有效地提高了射频连接器的屏蔽效果，改善了电学性能。
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。
