请一并参看图1、4和5，所述浮动支撑组件30包括具有收容腔34的基座31、安装在所述收容腔34内的定位块32、和连接在所述基座31和定位块32之间的弹性件33，所述收容腔34具有与基座31外部连通的开口3111，所述定位块32具有位于所述开口3111处的安装座321，所述安装座321用于收容待测试的传输线20的连接器22。测试时，当所述探针组件10与安装在安装座321上连接器22对位时，连接器22或安装座321接收到来自探针组件10的力，进而挤压弹性件33。弹性件33受到挤压后，可支撑所述定位块32在6个自由度（沿X/Y/Z的3个平动自由度，以及绕X/Y/Z 的3个旋转自由度，共计6个自由度）上在所述收容腔34内平动或旋转，从而测试探针组件10的若干探针15便可以精确抵压在连接器22之信号端子221上。完成测试后，所述弹性件33发生变形后产生的回复力用于将所述定位块32复位。
请再参看图4，所述定位块32还包括支撑所述安装座321的本体部323以及自所述本体部323的周向向外延伸的翼部322，所述弹性件33套设在所述本体部323外周，且所述弹性件33的一端与所述基座31抵接，所述弹性件33的另一端与所述翼部322抵接；所述基座31在所述开口3111处设有限位块312，所述限位块312与所述翼部322配合用于限制所述定位块32从所述收容腔34内弹出。

具体地，所述基座31包括具有所述收容腔34的底座311和盖合于所述底座311远离所述开口3111一侧的盖板35，所述弹性件33与所述盖板35抵接。
更为具体地是，所述盖板35安装在所述收容腔34内且通过紧固件36与所述底座311固定连接，所述盖板35上设有容纳所述弹性件33的容纳槽351，所述弹性件33与所述盖板35抵接的一端收容在所述容纳槽351内；具体地，所述盖板35包括与所述底座311抵接的盖合部352以及自所述盖合部352向所述收容腔34延伸的凸起部353，至少部分所述容纳槽351设置于所述凸起部353。
需要说明的是，本发明实施例中所有方向性指示（诸如上、下、内、外、顶部、底部……）仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
还需要说明的是，当元件被称为“固定于”或“设置于”另一个元件上时，该元件可以直接在另一个元件上或者可能同时存在居中元件。当一个元件被称为“连接”另一个元件，它可以是直接连接另一个元件或者可能同时存在居中元件。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
