Description

一种可快速拆装的高可靠性射频同轴连接器 技术领域
[0001] 本发明涉及射频同轴电缆连接器的技术领域， 具体为一种可快速拆装的高可靠 性射频同轴连接器。
背景技术
[0002] 行业***频同轴连接器与电缆连接器形式常用的是安装式、 焊接式及压接式。
针对安装式结构， 行业内都是通过螺纹旋接来实现的， 可进行拆卸。 安装式结 构的连接器相比其他两种结构价格偏贵， 但其优点在于在工程施工中使用灵活 ， 可以根据实际长度或接口形式需求做调整。 根据调研， 在工程施工中一个熟 练的施工人员安装一个连接器需要花费 2~3分钟， 对于一名新人， 按照安装说明 书安装一个连接器基本要花费 10~15分钟， 而且可能还安装不到位， 性能指标不 良。
[0003] 现在国内外同一型号的连接器内部结构基本大同小异， 其电气性能方面所凸显 的问题也基本一致， 特别是行业内关注比较多的动态互调。 针对动态互调的问 题， 我们也经过较多的试验分析， 除去材料及电镀问题， 连接器电缆夹对电缆 外导体的夹持及连接器插孔对电缆内导体的夹持能力量方面对互调起到较大的 影响作用。 常规的连接器对电缆外导体只有简单的夹持， 其余部位与电缆外导 体的空隙均比较大， 而在动态情况下就电缆外导体晃动会导致互调极不稳定， 同样的问题也出现在内导体夹持上， 故这两个因素对动态互调的稳定起到至关 重要的影响。
[0004] 随着基站***对各个组件性能的要求越来越高及人工施工成本的不断提高， 很 多国外厂家都在寻找性能稳定且易安装的连接器开发方案。

[0029] 前凸 41和第一定位孔 31在安装状态下过盈配合连接；
[0030] 电缆夹持组件 5包括底座 7、 电缆夹 8， 底座 7的外环面和后保护套 2的对应内环 面间过盈配合连接， 电缆夹 8的后端安装勾结构 81卡装于底座 7对应的外环面的 槽孔 71中， 电缆夹 8的内端环面的前部、 后部均设置有第一内环凸起 82、 第二内 环凸起 83 , 第一内环凸起 82、 第二内环凸起 83用于压接已经安装到位的电缆的 对应波谷， 电缆夹 8的前端面为对应于前壳体对应夹持内凹槽 12的前端夹持面 51
[0031] 电缆夹 8具体为若干瓣电缆夹结构 801圆周向拼合形成的圆环结构， 每个电缆夹 结构 801的后端安装勾结构定位于对应的槽孔 71内； 具体实施例中四瓣电缆夹结 构 801圆周向拼合形成的圆环结构的电缆夹 8 ;

[0036] 其工作原理如下： 先进行电缆的剥线及预装， 之后将电缆自后保护套的中心孔 插装进入同轴连接器， 确保电缆内导体已在中心导体的轴向尾部的贯穿孔内， 保证同心度的同时确保电缆内导体进入中心导体的贯穿孔内， 之后在压接过程 中， 电缆外导体顶住尖角结构， 电缆外导体受挤压弯曲变形， 外导体重叠， 被 夹持于电缆夹组件的前端夹持面和夹持内凹槽之间， 当作用于电缆的压接力足 够大时， 电缆发生位移， 同时顺带中心导体往前推进、 进而带动中心导体进入 第一定位孔内， 更好的紧固电缆内导体。
[0037] 其主要适用于内导体为铜管结构的电缆， 其具有以下特点：
[0038] 1连接器安装完成后为一体式结构， 无需在施工过程中对其进行分离， 只需推 入电缆到预定位置即可；
[0039] 2电缆夹为多瓣结构， 采用“钩状”结构及 0型圈保护使其放置在底座上形成一套 电缆夹组件， 可实现电缆装入过程中的张开与收缩， 另外电缆夹固定在后壳体 上， 确保电缆夹在撑开过程中有后壳体内壁限位， 防止电缆夹脱落；
[0040] 3电缆夹具有双波谷固定功能， 其表面具有一道半圆形槽；
[0041] 4连接器内导体具有锥度， 确保可以顺畅的进入电缆内导体， 其接触为为弹性 接触；
[0042] 5连接器在安装过程中电缆可随时拔出， 避免应安装问题导致连接器报废；
[0043] 6电缆夹与外导体的夹持采用双层铜带， 代替之前的单层夹持， 夹持更加牢靠
[0044] 7连接器安装采用前后壳体过盈配合压接完成， 代替常规的螺纹旋接结构， 同 时经过试验与电缆连接的抗拉强度明显大于常规螺纹旋接结构；
[0045] 8内部绝缘支撑具有高强度横向及纵向性能， 同时满足射频连接器电性能；
[0046] 9连接器尾端密封圈在压接过程中密封圈压缩变形， 与电缆护套紧密接触， 达 到防水效果。
