所述底座111还包括与所述限位块114连接、且围成所述开口1121的承托块115，所述安装座121远离所述盖板113的一侧抵接于所述承托块115。
所述探针部15安装于所述底座111远离所述导杆123的一侧，所述探针部15包括安装于所述底座111的电路板151、叠设于所述电路板151远离所述底座111一侧的安装件152、嵌设于所述安装件152的探针16以及设置于所述电路板151朝向所述底座111一侧的射频转接头154，所述定位块12设有贯穿所述导杆123和所述安装座121的镂空部122，所述射频转接头154收容在所述镂空部122内，所述探针16的两端裸露于所述安装件152外，且所述探针16的一端与所述电路板151抵接。具体请参看图4-6，所述安装件152远离所述电路板151的一侧设有导向结构153，所述导向结构153包括一卡槽1531以及围设形成所述卡槽1531的导向壁1532，所述导向壁1532用于引导所述安装件152与所述传输线20相对移动以使所述传输线20的连接器22收容至所述卡槽1531内，所述探针16的一端裸露于所述卡槽1531以用于与所述传输线20的信号端子221抵接。
请参看图5，所述导向壁1532远离所述电路板151一端的内侧面自靠近所述电路板151的一侧向远离所述电路板151的一侧向远离所述卡槽1531（也就是所述收容腔112的中轴线L）的方向逐渐延伸，以使所述卡槽1531的口径逐渐增大。所述盖板113上设有容纳所述弹性件13的容纳槽1131，所述弹性件13与所述盖板113抵接的一端收容于所述容纳槽1131内，所述盖板113上还设有贯穿其顶部以连通所述容纳槽1131与所述基座11的外部的避让孔1132。
请再参看图2，所述盖板113包括与所述底座111连接的盖合部1133和自所述盖合部1133朝向所述开口1121凸起的凸起部1134，所述容纳槽1131至少部分开设于所述凸起部1134，所述凸起部1134套设于所述导杆123外。
测试时，探针16的一端抵接电路板151，另一端抵接连接器22的信号端子221，从而将射频信号从传输线20输出至电路板151；射频转接头154与电路板151中的电路连接，并通过电缆与外部测试仪器连接，从而将已传输至电路板151的射频信号传输至外部测试仪器。具体的，电缆收容在镂空部122中，并从避让孔1132中穿出。
测试时，当探针部15的导向壁1532与待测的传输线20的连接器22接触、挤压并存在偏移时，所述导向壁1532受力进而通过定位块12挤压弹性件13发生形变，所述弹性件13发生形变后可支撑定位块12及其上的探针部15在上述的6个自由度内移动，最终在导向壁1532的引导下，所述探针部15能精确地将连接器22收容至卡槽1531内，此时探针16便可以精确与连接器22的信号端子221抵接，从而完成测试。测试完成后，所述弹性件13发生变形后产生的回复力将所述定位块12复位及其上的探针部15复位。
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。
