本发明还公开一种射频通信设备，如图3所示，射频通信设备包括如图1-图2中连接器、腔体15、盖板16和功放板18。连接器通过第一导体11和腔体15连接，其中，腔体15通过第一导体11的第二主体112和腔体15螺纹连接。
在本实施例中，盖板16设有第二通孔161，第二通孔161的内径L8大于连接器的第二导体14的外径L6，以使盖板16通过第二通孔161套设在连接器的第二导体14上并和腔体15连接。第二通孔161的内径L8小于绝缘固定件13的外径L7，以使得盖板16和腔体15连接后卡住绝缘固定件13。
通过上述方式，射频通信设备可以通过螺钉17将功放板18和第二导体14连接。在螺钉17锁紧功放板18和第二导体14后，第二导体14可以在一定间隙内上下移动，能够保证第二导体14与功放板18紧密接触，且同时保证功放板18不会因为受力过大而断裂。
下面结合上述说明本发明的射频通信设备的原理。
当安装射频通信设备时，先安装连接器，在安装连接器时，先将绝缘套管12套设在第一导体11的第一主体111上并和第一主体111过渡配合。随后再将绝缘固定件13通过第一通孔131套设在和绝缘套管12过渡配合的第一主体111上，以使得绝缘固定件13与和绝缘套管12过渡配合的第一主体111过渡配合并止挡于卡持部113。接着将设有容纳腔141的第二导体14插入和绝缘套管12过渡配合的第一主体111上，或者将第一导体11的第一主体111插设于第二导体14的设有绝缘套管12的容纳腔141内，以使得第二导体14与第一导体11的第一主体111过渡配合，且止挡于绝缘固定件13，从而实现安装好整个连接器。
在安装好连接器后，将第一导体11的第二主体112和腔体15螺纹连接以实现固定连接器和腔体15。再将盖板16套设在连接器上且同时盖板16止挡于绝缘固定件13。最后通过螺钉17将功放板18和第二导体14固定连接，从而实现整个射频通信设备的安装。
综上所述，本发明的连接器包括第一导体、第二导体、绝缘套管和绝缘固定件，第一导体包括有卡持部，绝缘固定件套设在第一导体上并止挡于卡持部，第二导体设有容纳腔，第一导体插设于容纳腔且使第二导体止挡于绝缘固定件，容纳腔内设有绝缘套管以将第一导体和第二导体之间绝缘隔离。通过以上方式，本发明的连接器结构简单，同时在加工过程中涉及的工序少，能够有效降低设计成本。
以上仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
