所述第五外导体45采用将料带冲卷包圆形成，所述料带为铍铜料带，此结构具有节约成本和延长寿命的作用。所述第五外导体45具有端部451和延伸部452，所述端部451连接于所述第四外导体44且位于第四外导体44内，所述端部451抵靠于所述第一凹槽441的外壁，所述延伸部452位于第四外导体44外。延伸部452的内径小于端部451的内径，端部451与延伸部452之间形成有第一阶梯453，所述第一阶梯453与第四外导体44上的斜坡442相配合接触。所述延伸部452向远离端部451的方向形成自由端，所述自由端的末端形成有凸起454，所述凸起454与第一外导体21接触，且自由端的末端向端部451方向延伸形成有数个缺口455，所述缺 口455的设置增加了第五外导体45的延伸部452的弹性，以满足较大的径向偏移量。所述凸起454在所述第五外导体45与所述卡紧插座2的第一外导体21的内壁接触时，能进一步加强与第一外导体21之间的接触，且所述缺口455和凸起454的设计便于第五外导体45安装在所述第三绝缘体43上。
所述第一外导体21与第五外导体45接触，所述第一外导体21具有内壁，所述内壁呈平面状，所述第五外导体45与所述内壁接触，使得卡紧插座2与转接器4具有±1.2mm的轴向偏移量，使得产品具有大容差和低互调的功能。所述第六外导体22设置有导引面221，所述导引面221用于导引所述第五外导体45与第一外导体21的内壁接触。
结合图6所示，所述转接器4的第三内导体42呈中空状，第三内导体42采用将料带冲卷包圆形成，其具有中间部位421和两端部位422，所述两端部位422的内径小于所述中间部位421的内径，该结构便于实现电镀，并节约成本。所述中间部位421与两端部位422的连接处形成有第二阶梯423，所述两个第三绝缘体43分别套设于两端部位422，所述两端部位422与第三绝缘体43之间实现同轴设置，所述第三绝缘体43的一端抵靠于第二阶梯423，另一端凸出于第三内导体42的两端部位422，即，所述第二阶梯423的设置，便于第三内导体42与第三绝缘体43之间的配合安装，第二阶梯423能够定位第三绝缘体43，避免第三内导体42的两端部位422接触第一绝缘体24与第二绝缘体33，影响产品的互调性能。所述两端部位422均设置有锥形夹持部424，用于分别夹持第一内导体23和第二内导体32，所述锥形夹持部424上形成有数个切口425，所述切口425使得锥形夹持部424更加有弹性，并且能够更好的稳固夹持所述第一内导体23和第二内导体32。
结合图7所示，所述第三绝缘体43采用注塑成型工艺加工而成，第三绝缘体43包括本体部431及环绕于本体部431设置的附加部432，所述本 体部431与附加部432之间形成数个第一通孔433，所述本体部431设有自其外圆周面向内凹陷形成的数个第二凹槽434，这样设计，节约成本且提升电性能。本体部431的中心部位设有轴向延伸的第二通孔435，所述第三内导体42的两端部位422安装于所述第二通孔435内，实现所述第三绝缘体43与所述第三内导体42同轴设置，这样设计，提高产品使用寿命和使用性能的同时，并且节约成本。
