射频连接器按照连接方式可以分为螺纹锁紧式、机械卡口式快插连接器、卡簧抱紧式快插连接器等多种连接器，当使用螺纹锁紧式连接器时，需要手工拧紧，连接器需要拧到位才可以保证测试数据的准确性，是否拧到位完全依靠人工的操作规范性，对人工操作要求比较高，且人工拧紧效率低，影响产品的生产和测试效率，增加了成本。
如图1至图3所示，图1示出本公开提供的一种锁紧式连接器的结构示意图，图2示出本公开提供的一种公端的局部剖视图，图3示出本公开提供的一种公端的爆炸 示意图。
本公开提供一种锁紧式连接器，包括可拆卸连接的公端1与母座2，母座2沿自身长度的一端的外周侧设置有凸出部21。公端1包括导体组件11、滑套12、滚珠13以及锁套14，滑套12套设于导体组件11的外周侧，滑套12沿自身轴向的一端与导体组件11之间设置有与凸出部21配合的间隙；滚珠13设置于滑套12内，滚珠13可朝向或远离间隙移动；锁套14套设于滑套12的外周侧且与滑套12可滑动连接，锁套14远离滚珠13的一端设置有锁止件141，滑套12沿自身轴向设置有间隔分布的第一锁止槽121和第二锁止槽122，锁止件141位于第一锁止槽121时，凸出部21伸入间隙并与滚珠13卡接，锁止件141位于第二锁止槽122时，凸出部21从间隙退出并与滚珠13分离。
需要理解的是，锁紧式连接器可以是射频连接器。锁紧式连接器包括母端2，母座2沿自身长度设置有第一端与第二端，母座2的第一端的外周侧设置有凸出部21，凸出部21与母座2一体式成型设置。
公端包括导体组件11，导体组件11包括内导体111、绝缘体112以及外导体113，内导体111与外导体113均采用导电材料，绝缘体112采用绝缘材料，绝缘体112套设于内导体111且与内导体111固定连接，外导体113套设于绝缘体112且与绝缘体112固定连接，内导体111为两个电气系统之间提供传导的路径，外导体113也为两个电气系统之间提供传导的路径，绝缘体112为与内导体111与外导体113之间进行绝缘。
公端还包括滑套12，滑套12套设于导体组件11的外周侧，滑套12沿自身轴向的一端与导体组件11之间设置有间隙。滑套12的一端与外导体113贴合，滑套12的另一端与外导体113之间具有空隙，当母座2与公端连接时，母座2的凸出部伸入间隙处。滑套12于外导体113之间设置有间隙的一端设置有滚珠13，滚珠13沿滑套12径向来回移动，使得滚珠13可伸入间隙或伸出间隙。
滑套12的外周侧还套设有锁套14，锁套14与滑套12可滑动连接，锁套14远离滚珠13的一端设置有锁止件141，滑套12沿自身轴向间隔设置有适配于锁止件141的第一锁止槽121以及第二锁止槽122。当锁止件141位于第一锁止槽121或第二锁止槽122中时，锁套14与滑套12锁定，不再相对滑动。且当锁止件141位于第一锁 止槽121中时，滚珠13在锁套14的驱使力下朝向间隙移动，此时滚珠13与凸出部21朝向母座2第二端的侧壁抵接，凸出部21与滚珠13的设置将母座2与公端1进行锁止。当锁止件141位于第二锁止槽122时，滚珠13与凸出部21脱离，即母座2与公端1分离。
其中锁止件141可呈块状，也可呈环状，锁止件141设置于锁套14的内壁，锁止件141可与锁套14一体成型，也可与锁止件141可拆卸连接。在一个示例中，锁套14的内壁开设有安装槽，锁止件141为卡簧且安装于安装槽中，此时第一锁止槽121与第二锁止槽122均为环槽。
参照图4、图5，图4示出示出本公开提供的一种公端与母端连接前的示意图；图5示出示出本公开提供的一种公端与母端连接后的示意图。当需要将母座2与公端1连接时，将母座2的第一端插入公端1中，此时母座2的凸出部21伸入滑套12与导体组件11之间的间隙处，操作者滑移锁套14，锁止件141从第二锁止槽122处移动到第一锁止槽121处，使得锁套14朝向滚珠13的一端运动，锁套14驱使滚珠13沿滑套12的径向移动，滚珠13的一部分伸入间隙处且与凸出部21朝向母座2的第二端抵接，锁套14与母座2将滚珠13进行夹持，避免滚珠13沿滑套12的径向移动，从而将母座2与公端1连接。当需要将母座2与公端1分开时，操作者将锁套14朝向远离滚珠13的一端移动，使得锁止件141从第一锁止槽121移动到第二锁止槽122处，此时，滚珠13可沿锁套14的径向移动，然后将母座2的凸出部21从滑套12与导体组件11之间的间隙处去除，从而将母座2与公端1分离。
本公开相对于螺纹式锁紧连接器来说，不需要手工拧紧，不需要依靠人工操作规范性，降低了人工成本，相对于机械卡扣式快插连接器来说，锁紧位置为母座2的尾端，不容易收到射频测试线的影响，从而提高测试结果的准确性。
在一示例性实施例中，母座2的凸出部21呈块状且设置有多个，多个凸出部21沿母座2的外周侧环形排布。母座2的凸出部21还可呈环状。此时，为了提高滚珠13与凸出部21卡合效果，滚珠13设置有多个，多个滚珠13环绕母座2的外周侧排布。
参照图3-图5，在一些示例性实施例中，凸出部21沿母座2长度方向的两端均设置有斜面，且斜面的倾斜方向相反。在一个示例中，凸出部21呈螺纹设置。凸出部 21的长度沿背离母座2的方向逐渐缩小，即凸出部21的大端与母座2连接，且形成凸出部21的两个斜面。凸出部21的斜面设置，从而使得凸出部21插入或伸出滑套12与导体组件11之间的间隙更加容易，使得母座2与公端1的连接与分离更加方便。
在一些示例性实施例中，滑套12开设有用于安置滚珠13的滚珠孔，滚珠孔朝向滑套12内腔的一端内径小于滚珠13的直径。滚珠孔贯穿滑套12的套壁，滚珠孔朝向滑套12内腔的一端内径小于滚珠13的直径，从而避免滚珠13朝向滑套12的内腔脱离。在一个示例中，滚珠孔的内径朝向滑套12的内腔方向逐渐缩小。
在一些示例性实施例中，锁套14朝向滚珠13的一端开设有限制滚珠13脱离滑套的限位腔142，限位腔142的内壁与导体组件11之间的距离小于滚珠13的半径。限位腔142背离锁止件141的一端开口设置，当公端1与母座2分离时，限位腔142与滚珠孔相对应，滚珠13位于滚珠孔中，且部分滚珠13与限位腔142的腔壁抵接，限位腔142的内壁与导体组件11之间的距离小于滚珠13的半径，从而避免滚珠13从滚珠孔中脱离的几率。当母座2与公端1连接时，锁套14朝向滚珠13一端滑移，此时，限位腔142与滚珠孔错位设置，此时锁套14内壁与滑套12的外壁抵接，驱使滚珠13朝向滑套12的内腔移动。
在一示例性实施例中，限位腔142的轴肩面倾斜设置，当母座2与公端1连接时，锁套14朝向滚珠13一端滑动更顺畅。
在一些示例性实施例中，滑套12在滚珠13一端开设有引导腔125，引导腔125的腔径沿背离滚珠3的方向逐渐扩大。母座2与公端1连接时，引导腔125的设置便于母座2的第一端伸入公端1，提高母座2与公端1连接的顺畅性。
在一些示例性实施例中，滑套12与导体组件11滑移连接，导体组件11的外周侧设置有凸环1131，凸环1131位于间隙中，间隙中还设置有弹性件15，弹性件15的一端与凸环1131抵接且另一端与滑套12的轴肩抵接。
在一个示例中，滑套12可与外导体113固定连接，从而使得本公开的公端只适配于一种母座2。
在另一个示例中，滑套12与外导体113滑移连接，外导体113的外周侧一体成型有凸环1131，凸环1131位于滑套12与外导体113之间的间隙处，间隙中还设置有弹性件15，弹性件15的一端与凸环1131抵接且另一端与滑套12的轴肩抵接。当母座2 伸入公端1时，母座2的第一端与凸环1131抵接，不同的母座2伸入公端1时，弹性件15可根据母座2第一端的长度进行伸缩，从而调节凸环1131的位置，从而使得公端1适配于多种不同型号的母座2，进而提高公端1的适用性。
其中，弹性件15可以为任何弹性材质，例如弹簧、弹性树脂等材质，在一个示例中，弹性件15为弹簧，弹簧套设于外导体113的外周侧。
在一些示例性实施例中，导体组件11外周侧远离滚珠13的一端设置有第一凹槽1132，第一凹槽1132内设置有第一挡件1133，第一挡件1133凸出导体组件11的外壁。第一凹槽1132设置于外导体113的外周侧，第一凹槽1132为环槽，第一挡件1133呈环状可通过固定于第一凹槽1132中，也可卡接于第一凹槽1132中，第一挡件1133可为凸起块、挡圈或其他限位组件。在一个示例中，第一挡件1133为挡圈且卡接于第一凹槽1132中。第一挡件1133凸出外导体113的外周侧，即当滑套12朝向背离滚珠13一端滑动时，第一挡件1133对滑套12进行阻挡，从而避免滑套12从外导体113处脱落。当母座2与公端1分离时，滑套12的端部与第一挡件1133抵接。
在一些示例性实施例中，滑套12远离滚珠13的一端设置有第二凹槽123，第二凹槽123内设置有第二挡件124，第二挡件124凸出滑套12的外壁。第二凹槽123为环槽，第二挡件124呈环状可固定于第二凹槽123中，也可卡接于第二凹槽123中，第二挡件124可为凸起块、挡圈或其他限位组件。在一个示例中，第二挡件124为挡圈且卡接于第二凹槽123中。第二挡件124凸出滑套12的外周侧，即当锁套14朝向背离滚珠13一端滑动时，第二挡件124对锁套14进行阻挡，从而避免锁套14从滑套12处脱落。当母座2与公端1分离时，锁套14的端部与第二挡件124抵接。
在一些示例性实施例中，锁套14的外周侧设置有多条防滑棱143。多条防滑棱143的设置可增加锁套14与操作者之间摩擦力，从而便于操作者操作。在一个示例中，防滑棱143呈圆环状，多条防滑棱143沿锁套14的长度方向排布。在一个示例中，多条防滑棱143在锁套14的外周侧杂乱排布。
在一些示例性实施例中，导体组件11远离滚珠13的一端设置有连接部1134，连接部1134位于导体组件11的外周侧。连接部1134设置于外导体113的外周侧且远离滚珠13的一端，在一个示例中，连接部1134为螺纹连接便于与其他零件连接。
通过本公开提供的锁紧式连接器，包括可拆卸连接的公端和母座，母座沿自身长 度的一端的外周侧设置有凸出部，公端包括导体组件、滑套、滚珠以及锁套；滑套套设于导体组件的外周侧，滑套沿自身轴向的一端与导体组件之间设置有与凸出部配合的间隙；滚珠设置于滑套，滚珠可朝向或远离间隙移动；锁套套设于滑套的外周侧且与滑套可滑动连接，锁套远离滚珠的一端设置有锁止件，滑套沿自身轴向设置有间隔分布的第一锁止槽和第二锁止槽，锁止件位于第一锁止槽时，凸出部伸入间隙并与滚珠卡接，锁止件位于第二锁止槽时，凸出部从间隙退出并与滚珠分离。公端通过滚珠与母座的凸出部卡接，通过锁止件进入第一锁止槽中锁定滚珠，从而使得公端与母座稳定连接，且不需要操作者将公端与母座进行旋转拧紧，从而提高公端与母座连接的便捷性，降低成本。
