本实施例中，公端屏蔽辅板通孔内侧四周设有连通公端接地端子的定位凸点243。定位凸点保证公端屏蔽辅板与公端接地端子接通的同时，使公端接地端子定位在公端屏蔽辅板通孔，防止公端接地端子晃动。
本实施例中，母端接地端子42的插接端设有与公端接地端子配合卡接的母端接地端子插接弹性卡片423。当公端接地端子插入到母端接地端子内时，母端接地端子插接弹性卡片把公端接地端子卡紧，保证了母端接地端子和公端接地端子连接的紧固性和精确性。
本实施例中，母端固定座3包括有母端固定座底座31，以及设于母端固定座底座内的一个以上的母端固定座单体32，母端信号端子固定在母端固定座单体上，母端接地端子42包括有插接在母端固定座单体上的U形的第一母端接地端子424和与把第一母端接地端子的U形开口封住的第二母端接地端子425。第一母端接地端子和第二母端接地端子使母端接地端子的截面形成一个封闭的结构，母端接地端子把信号端子包裹，母端屏蔽片堵住母端接地端子的压接端开口，从而防止不同组母端信号端子之间的信号干扰，屏蔽效果好。
本实施例中，两个以上的母端固定座单体并排设于母端固定座底座内，母端接地端子42的侧面设有用于把母端接地端子卡接定位在母端固定座底座内的定位弹性卡片426。当母端固定座单体上的母端接地端子和母端信号端子固定之后，母端固定座单体并排置于母端固定座内，母端接地端子侧面的定位弹性卡片使相邻母端固定座单体上的母端接地端子相互挤压卡紧在母端固定座底座内。
本实施例中，母端接地端子42上设有用于接通母端屏蔽片的母端导通凸起427，母端屏蔽片43上设有与母端导通凸起配合卡接的母端导通槽431。母端导通凸起卡接在母端导通槽内，从而使所有的母端接地端子连通形成一个屏蔽网。
本实施例中，公端固定座1上设有U形导向槽12，母端固定座3上设有与U形导向槽配合的导向凸台31，导向凸台的插入端设有导向斜面32。从而便于公端连接头和母端连接头的插拔。
虽然结合附图对本发明的具体实施方式进行了详细地描述，但不应理解为对本发明的保护范围的限定。在权利要求书所描述的范围内，本领域技术人员不经创造性劳动即可做出的各种修改和变形仍属于本发明的保护范围。
