Coaxial connector with floating mechanism

The invention provides a coaxial connector with a floating mechanism. The coaxial connector with the floating mechanism ensures floating performance, has a small number of components, can be miniaturized, and has excellent high-frequency performance. In a coaxial connector (1) with a floating mechanism, a plug-side housing (4) is provided with: a housing main body (41) that holds a plug-side center contact (3) and a plug-side insulator (5); and a movable housing (42) which is swingably supported by the housing main body (41) and fitted into a socket-side housing (7), the housing main body (41)being provided with an insertion recess (413) which opens at the socket-side end surface and into which a seat-body movable part (82) is inserted, whereby high frequency performance can be obtained. 本发明提供一种确保浮动性能的同时部件个数少且能小型化，高频率性能优异的带浮动机构的同轴连接器。在带浮动机构的同轴连接器(1)中，在插头侧壳体(4)具备：壳体主体(41)，保持插头侧中心接触件(3)和插头侧绝缘体(5)；以及可动壳体(42)，以可摆动的方式支承于壳体主体(41)，与插座侧壳体(7)嵌合，在壳体主体(41)具备：插入用凹部(413)，在插座侧端面开口，供座体可动部(82)插入，由此能得到高的高频率性能。
