具体实施方式
下面结合具体实施例对本发明做进一步详细的描述，但本发明的实施方式不限于此。
实施例1：
如图1、图2、图3、图7、图8所示，一种圆形集束防水快插型射频连接器，包括插座1和插头2，其中，插座1包括壳体11，设置于壳体(11)内的环形绝缘体一13，设置于环形绝缘体一13内的插针16和设置于插针16头部的保护壳15，保护壳15向外延伸形成一个环形腔体，插针16完全位于该腔体内，避免了插针16由于外力而损坏；每个插针16为一个内导体，每个插针16单独设置于一个环形绝缘体一13中，信号在插座1中可以沿着插针16外表面和导电的外壳21及保护壳15内表面进行传输。
插头2包括外壳21，设置于外壳21内的单芯连接器3，单芯连接器3通过活动螺母29与外壳21固定连接；插针16和单芯连接器3的数量相等且至少为两个，当插座1和插头2插合时，每个插针16插入对应的单芯连接器3传输信号。
实施例2：
在实施例1的基础上，如图4所示，本发明的一种圆形集束防水快插射频连接器单芯连接器3剖视图，单芯连接器3包括单芯外壳31、设置于单芯外壳31前端的导电弹性接触件34、内设于单芯外壳31的环形绝缘体二33和内设于环形绝缘体二33、且与环形绝缘体二33同轴设置的插孔32。
当插座1和插头2插合时，如图5所示，插座1的壳体11先伸入到插头2的外壳21腔体内，保证单芯连接器3对插时的同心度，可以避免插针16与插孔32、保护壳15与导电弹性接触件34对插过程中，因为斜插导致插孔32、导电弹性接触件34损坏。单芯连接器3中的插孔32为带劈槽的圆柱形插孔32，能够提供稳定的接触正压力保证与插针16稳定接触，信号沿着插孔32和单芯外壳31内表面进行传输，此时导电弹性接触件34与插座1上的保护壳15内表面接触，导电弹性接触件34处于收缩状态，可以提供稳定的接触正压力，保证与保护壳15内表面形成稳定接触，保证能够组成信号通路，并能够保证有较好的PIM互调指标。
实施例3：
在实施例1的基础上，如图6所示，活动螺母29上设置有外密封圈27和内密封圈28，单芯连接器3装配焊接电缆后，穿入插头2的外壳21内，并用活动螺母29锁紧，活动螺母29上的外密封圈27和内密封圈28保证了单芯连接器3安装后，插头2尾部的密封性。
实施例4：
在实施例1的基础上，插头2还包括外壳21内部设置的环形簧片24和套设于外壳21上的解锁套23，如图9、图10所示，解锁套23和外壳21之间设置有弹簧25和密封圈一22，保证解锁套23与外壳21外部密封圈可靠配合，有效的起到密封作用，同时也可保证解锁动作完成后，解锁套23迅速复位。
壳体11上设置有凹槽，插头2和插座1插合时，将插头2推入到固定在板机上的插座1时，环形簧片24先涨开，然后收缩在壳体11上的凹槽内，保证插头2和插座1轴向不分离，并能够承受较大的轴向拉力，解锁时，拉动解锁套23，使得环形簧片24涨开，环形簧片24与凹槽分离，实现插头2从插座1内部退出。
壳体11上还设置有螺纹，可以实现与螺纹连接器的螺纹连接，提升了展品的适用性。
实施例5：
在实施例1的基础上，如图2、图3、图7、图8所示，插座1与插头2连接的一端设置有一个主键槽17和多个副键槽，且主键槽17和副键槽不对称分布，插头2与插座1连接的一端设置有一个主键26和多个副键，且主键26、副键和主键槽17、副键槽位置一一对应。
插座1口部设置的主键槽17外部设置有明显标识，与之对应的插头2的外壳21口部设置的主键26外部也设置有明显标识，且主键26和副键的位置与插座1主键槽17和副键槽的位置一一对应，这样就可以通过键与键槽的配合来实现插座1与插头2对接的准确定位，有效地提高了插座1与插头2对接的准确性。
实施例6：
在实施例1的基础上，如图2、图7所示，壳体11外部和内部分别设置有密封圈二14和密封圈三12，插座1不与插头2连接的一端设置有法兰盘18，法兰盘18上设置有密封圈四19。
插座1的外壳21后端设置的法兰盘18以及密封圈四19，可以与设备机板安装固定，同时在插座1的外壳21内外均设置有密封圈三12和密封圈二14，保证对插后，连接器端面与界面处都具有防水功能，提高连接器环境适应性。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
