且该天线转接装置还包括第三接口 3 和单刀双掷开关 4 ，该单刀双掷开关 4 的设置方式多种多样，本发明中的单刀双掷开关 4 优选的设置在收容腔体内，这样设置的好处在于能使得该天线转接装置的结构更加紧凑，体积更小，使用起来更加的方便。
该第三接口 3 的主要作用在于作为射频信号的另一个输出端，使得使用该天线转接装置即可以连接手持天线 300 ，又可以连接外置天线 400 ，再结合单刀双掷开关 4 的切换功能，从而能使得具有该无线转接装置的无线设备能够通过切换使用不同的天线以适应不同环境。
则该单刀双掷开关 4 的动端 41 与第一接口 1 电性连接，单刀双掷开关 4 的第一静端 42 与第二接口 2 电性连接，单刀双掷开关 4 的第二静端 43 与第三接口 3 电性连接。该单刀双掷开关 4 的选择多种多样，本发明中的单刀双掷开关 4 优选的为磁控开关。
如图 1 至图 4 所示，该第三接口 3 包括相互绝缘的射频金属圈 31 和地金属圈 32 ，射频金属圈 31 设置在第二金属外壳 21 的外侧，且射频金属圈 31 与第二金属外壳 21 相互绝缘；地金属圈 32 设置在第一金属外壳 11 的外侧，且地金属圈 32 与第一金属外壳 11 相互绝缘。
该射频金属圈 31 和地金属圈 32 设置在该天线转接装置的侧面，第一接口 1 和第三接口 3 通过单刀双掷开关 4 导通连接时，射频信号从第三接口 3 的射频金属圈 31 输出，并通过地金属圈 32 接地。而且地金属圈 32 没有与第一金属壳体和第二金属壳体中的任何一个相接触，且与第一金属壳体和第二金属壳体互相绝缘。即第三接口 3 的接地端与第一接口 1 和第二接口 2 的接地端之间通过绝缘介质形成了电容耦合，使得在通过所需信号地回流的同时，隔离了直流或低频干扰的地回流。 从而弱化了外界环境中的直流 / 低频干扰通过外接天线对无线设备造成的影响。
在一些实施例中，如图 1 至图 4 所示，该天线转接装置还包括第一绝缘挡圈 5 ，第一绝缘挡圈 5 的主要作用在于使得第一金属外壳 11 和地金属圈 32 相互绝缘，可以理解地，要使得第一金属外壳 11 和地金属圈 32 相互绝缘的方式有多种，除了使用该第一绝缘挡圈 5 外，还可以在第一金属外壳 11 和地金属圈 32 之间填充足够的绝缘材料，或者在第一金属外壳 11 和地金属圈 32 之间充入一定量的惰性气体等等。
该第一绝缘挡圈 5 设置在地金属圈 32 与第一金属外壳 11 之间，且本发明中的第一绝缘挡圈 5 优选的套设在该第一金属外壳 11 的外侧，该地金属圈 32 套设在该第一绝缘挡圈 5 的外侧，为了能简单方便的安装该地金属圈 32 ，第一绝缘挡圈 5 的底部设置有用于限位地金属圈 32 的第一法兰盘 51 。从而在组装该天线转接装置的时候，只需要依次将第一金属外壳 11 、第一绝缘挡圈 5 和地金属圈 32 嵌套在一起并固定即可。
进一步地，该天线转接装置还包括第二绝缘挡圈 6 和绝缘压环 7 ，第二绝缘挡圈 6 的主要作用在于使得射频金属圈 31 和第二金属外壳 21 相互绝缘，可以理解地，要使得射频金属圈 31 和第二金属外壳 21 相互绝缘的方式有多种，除了使用该第二绝缘挡圈 6 外，还可以在射频金属圈 31 和第二金属外壳 21 之间填充足够的绝缘材料，或者在射频金属圈 31 和第二金属外壳 21 之间充入一定量的惰性气体等等。
该第二绝缘挡圈 6 设置在射频金属圈 31 与第二金属外壳 21 之间，且本发明中的第二绝缘挡圈 6 优选的套设在该第二金属外壳 21 的外侧，该射频金属圈 31 套设在该第二绝缘挡圈 6 的外侧，为了能简单方便的安装该地金属圈 32 ，第二绝缘挡圈 6 的底部设置有用于限位射频金属圈 31 的第二法兰盘 61 。从而在组装该天线转接装置的时候，只需要依次将第二金属外壳 21 、第二绝缘挡圈 6 和射频金属圈 31 嵌套在一起并固定即可。另外，本发明的第二金属外壳 21 设置在第一金属外壳 11 的上方，则该第二绝缘挡圈 6 的第二法兰盘 61 还具有隔开射频金属圈 31 与地金属圈 32 的作用，从而能保证第三接口 3 的射频金属圈 31 与绝缘挡圈之间相互绝缘。
更进一步地，该天线转接装置还包括绝缘压环 7 ，该绝缘压环 7 设置在第二金属外壳 21 的外侧，并位于射频金属圈 31 的上方。该绝缘压环 7 的主要作用在于补偿该射频金属圈 31 和第二金属外壳 21 之间的高度差，并能起到一定的固定射频金属圈 31 的作用。可以理解地，要使得该射频金属圈 31 固定的方式有多种，除了使用该绝缘压环 7 外，还可以通过绝缘螺母螺纹连接在射频金属圈的上方以固定，或者通过多个绝缘垫片将射频金属圈固定等等。
在一些实施例中，连接上述第三接口 3 的射频金属圈 31 和单刀双掷开关 4 的第二静端 43 的方式多种多样，本发明中的第三接口 3 优选的包括第三信号导线 33 ，第三信号导线 33 的一端与单刀双掷开关 4 的第二静端 43 连接，第三信号导线 33 的另一端与射频金属圈 31 的内侧面连接。可以理解地，第三接口 3 的射频金属圈 31 和单刀双掷开关 4 的第二静端 43 还可以通过一信号导体连接，或者在第三接口 3 的射频金属圈 31 的内侧面设置常见的导通材料，该导通材料延伸至该单刀双掷开关 4 的第二静端 43 以实现连接等等。
进一步地，第二金属外壳 21 的侧面可开设有供第三信号导线 33 伸出的第一开口 211 ，对应第一开口 211 ，第二绝缘挡圈 6 的侧面可开设有供第三信号导线 33 伸出的第二开口 62 。
在一些实施例中，连接上述第一接口 1 的第一中心导体 12 和单刀双掷开关 4 的动端 41 的方式多种多样，本发明中的第一接口 1 优选的包括第一信号导线 14 ，第一信号导线 14 的一端与单刀双掷开关 4 的动端 41 连接，第一信号导线 14 的另一端与第一中心导体 12 连接。
在一些实施例中，连接上述第二接口 2 的第二中心导体和单刀双掷开关 4 的第一静端 42 的方式多种多样，本发明中的第二接口 2 优选的包括第二信号导线 24 ，第二信号导线 24 的一端与单刀双掷开关 4 的第一静端 42 连接，第二信号导线 24 的另一端与第二中心导体连接。
本发明还提供了一种无线通信装置，该无线通信装置具有上述的天线转接装置，则该无线通信装置既可以适应室内或车内环境，又可以适应室外或车外环境。且该无线通信装置在使用外接天线时，基本不会出现外界环境中雷电等通过外接天线进入并损毁无线设备的情况。

具体使用时，第一接口 1 通过标准转接头连接到无线通信收发器 200 的信号输出端，第二接口 2 通过标准转接头直接连接到手持天线 300 ，第三接口 3 以触点接触的方式将信号导出到同轴线 410 ，并通过同轴线 410 连接到室外或车外的外置天线 400 。
当无线通信收发器 200 用作手持机时，射频信号从无线通信收发器 200 进入天线转接装置 100 的第一接口 1 ，并经过单刀双掷开关 4 将射频信号送到第二接口 2 连接的手持天线 300 ，由手持天线 300 向外辐射出电磁波；
