图 10中， 缺省部分防水罩， 以更清晰地展示防水罩内的插头结构。 解锁套 16与锁部 14之间为间隙配合， 可自由浮动。 具体地， 如图 11 所示， 所述解锁套 16的解锁操作部 161与所述壳体 13之间可设置有滚珠 42, 所述锁部 14的支撑圈 141与所述壳体 13之间可设置有弹性垫圈 41 , 以实现解锁套 16和锁部 14之间的浮动。 如图 12所示， 弹性垫圈 41为波 浪形的环形弹性圈。解锁套 16与锁部 14套接后， 弹性垫圈 41位于锁部 14 的支撑圈 141内， 为支撑圈 141起到弹性支撑作用； 滚珠 42位于解锁操作 部 161与所述壳体 13之间， 使解锁操作部 161悬浮在壳体 13的外围。 当 对解锁操作部 161施力时， 滚珠 42随之滚动， 能够减少解锁操作部 161与 壳体 13之间的摩擦。
解锁套 16与锁部 14之间的浮动方式可不限制于上述波形垫圈加滚珠 的方式， 只要能使解锁操作部 161相对于锁部 14移动即可。
图 11中， 缺省部分解锁套、 部分锁部、 部分壳体及部分绝缘体， 以更 清晰地展示插头的内部结构。
如图 13所示， 锁部 14的卡爪 142内侧设置有弹性支撑件 14A。 如图 1 4所示， 弹性支撑件 14A为带有缺口的弹性圈。 通过在卡爪 142的倒钩内 侧设置弹性支撑件， 同时插头中设置弹性支撑件， 增强了锁部 14的卡爪 1 42弹性功能， 使得锁部 14可重复锁紧、 解锁， 满足了同轴连接器多次插拔 的要求。
卡爪 142内侧不限于使用弹性支撑件 14A, 只要能对卡爪 142起到弹 性支撑作用即可。
图 13中， 缺省部分防水罩、 部分解锁套、 部分锁部、 部分壳体及部分 绝缘体， 以更清晰地展示插头的内部结构。
卡爪 142通过弹性支撑件 14A支撑， 确保卡爪 142弹性可靠。
如图 15所示， 同轴连接器的插座包括： 中心导体 21、 设置于所述中心 导体 21外围的绝缘体 22及设置于所述绝缘体 22外围的壳体 23。
图 15中， 缺省部分壳体 23、 部分绝缘体 22、 部分第一密封圈 24、 部 分第二密封圈 25, 以更清晰地展示插座的内部结构。
所述壳体 23上与插头插接的部分为环形槽； 环形槽包括内壁 231、 外 壁 232。
所述环形槽的外壁 232内侧设置有与插头的卡爪 142的倒钩相匹配的 沟槽 31 , 用于实现锁紧功能。
所述环形槽的底部可设置有第一密封圈 24。
所述壳体 23的外表面即外壁 232外侧设置有与防水罩 17内壁螺纹相 匹配的螺纹。
所述壳体 23上的螺纹退刀槽处可设置有与所述防水罩 17 内径相匹配 的第二密封圈 25。 也即第二密封圈 25可作为同轴连接器的插头的一部分， 也可作为同轴连接器的插座的一部分。
插座部分在标准的 DIN头同轴连接器的插座基础上进行优化， 在插座 的环行槽外壁内侧增加沟槽 31 , 该沟槽与卡爪 142的倒钩斜面 32匹配， 同 时环行槽内置放第一密封圈 24, 外连接螺纹退刀槽处增加第二密封圈 25 , 插座的优化即实现了快插自锁功能的实现， 同时保留了标准 DIN头同轴连 接器的插座的特征， 实现了向上兼容。
本发明实施例提供的同轴连接器包括插头及插座， 插头和插座可实现 快速插合和分离。 其中， 插头可为上述实施例提供的任一种同轴连接器的 插头。， 插座可为上述实施例提供的任一种同轴连接器的插座。
如图 16A所示， 当插头与插座插合后， 能发出 "咔嗒 "的声音使得操作 者可判断是否插合到位， 插头中弹性圈 15的上表面 33和插座中环形槽内 壁 231的顶部表面 34完全接触， 有效地保证了电缆晃动时的导电可靠性。 并且， 如图 16B所示， 卡爪 142的倒钩落入沟槽 31 , 卡爪 142的悬臂梁处 于受力状态， 实现了插头与插座之间的机构锁紧。
图 16A中， 缺省部分解锁套、 部分锁部、 部分壳体及部分绝缘体， 以 更清晰地展示插头与插座配合的结构。
解锁时， 用手抓住解锁操作部 161向后拉解锁套 16, 缺口 162的上边 框对卡爪 142的倒钩斜面 32产生向下作用力， 该向下作用力 的水平方向 上的分量使得卡爪 142向插头的中心收缩， 从而卡爪 142的倒钩退出沟槽 31 , 此时， 拉拔插座， 实现插头与插座的分离。
如图 17所示， 同轴连接器还包括防水罩 17。 防水罩 17可与插座单独 分体实现， 也即可与插头一体设计。
图 17中， 缺省部分防水罩， 以更清晰地展示同轴连接器的内部结构。 插头和插座配合本身就具备有 IP68的防水效果， 在插头上增加了防水 罩 17, 是为了达到更好的户外天馈系统的防水效果。 插头和插座插合后， 用手旋紧防水罩 17, 整个同轴连接器机构达到了最好的防水状态。
防水罩部分带有标准的螺纹， 同时内置密封圈。 具体地， 防水罩 17可 自带尾部密封圈 18和第二密封圈 25 , 通过螺纹连接的方式和插头、插座保 持紧密连接， 即使在恶劣的环境， 也能保证插头和插座的高可靠性应用。
插头和插座配合后，插座内置的第一密封圈 24被压缩，起到防水作用。 当用手旋紧防水罩， 插座上的第二密封圈 25同时被压缩， 防水罩内置的尾 部密封圈 18同时也被收缩， 这样， 同轴连接器整体有双重防水功能， 同时 可防尘、 盐雾， 插头和插座配合后的相互晃动也随之消除， 提高了同轴连 接器户外应用的可靠性。
其中， 尾部密封圈 18可不限于两个或其他防水形式， 防水罩 17和插 头可为一体实现结构， 整个插头和插座的操作过程用旋紧的方式实现， 旋 紧防水罩的过程中会自动带动插头和插座的配合。 上述实施例提供的插头、 插座及同轴连接器， 对传统的螺纹安装方式 进行了改进， 有效的提高了安装操作效率， 减少了操作时间， 节约了人工 成本以及免操作工具的实现方式。 同时降低人员的操作技能要求， 实现了 传统的天馈接口免胶泥胶带的防水保护方式， 确保了天馈接口的长期可靠 性工作。
上述实施例提供的同轴连接器不局限于天馈同轴连接器， 任何同轴连 接器皆适用， 插头中锁部的卡爪数量不受限制， 内置弹性支撑件不限于使 用弹性圈或者其他方式实现。 防水罩与插头、 插座的连接不限于使用螺纹 连接方式， 解锁套的浮动方式不限制于使用波形垫圈加滚珠的方式。
最后应说明的是： 以上实施例仅用以说明本发明的技术方案， 而非对 其限制； 尽管参照前述实施例对本发明进行了详细的说明， 本领域的普通 技术人员应当理解： 其依然可以对前述各实施例所记载的技术方案进行修 改， 或者对其中部分技术特征进行等同替换； 而这些修改或者替换， 并不 使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
