当情况下，上述技术、方法和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
如图1-图6所示，一种具有锁止构件的连接器，包括：
连接器壳体1，连接器壳体1内设置贯通的腔体11，连接器壳体1的侧壁设置有与腔体贯通的开窗12；

以及锁止构件3，锁止构件3经由开窗12安装于连接器壳体1内，锁止构件3至少部分插入开口223形成的空间内，并限制端子组件2在腔体11内的轴向移动。
具体地，端子组件2包括第一外导体21和第二外导体22，且第一外导体21和第二外导体22都具有腔体；第一外导体21插入第二外导体22的腔体内，且第一外导体21和第二外导体22的腔体是相通的，同时第一外导体21的外表面或端面与第一腔体的内壁和/或第二腔体的端面或第二腔体的内壁环形抵接，使第一外导体21和第二外导体22构造成的一体屏蔽结构；在第一外导体21和第二外导体22构造成的一体屏蔽结构的前提下，将第二外导体22的固定段221的侧壁上开设至少一个开口223，因第一外导体21的外表面或端面与第二外导体22的内表面或端面进行环形抵接，使开口223与第二外导体22的外边面形成一定的凹陷空间，相当于传统外导体增加向内的凸台后形成的凹槽，这样既保证了导体的屏蔽性能，又形成了便于与锁止构件3卡接的结构，制作工艺简单，节约制作成本。
更具体地，连接器壳体1内设置贯通的腔体11，且在其侧壁设置有与腔体贯通的开窗12，锁止构件3经开窗12安装在连接器壳体1内。锁止构件3至少部分的插入开口223与第一外导体21形成的空间内，以实现端子组件2在连接器壳体1的腔体11内的轴向移动，起到了定位的作用，同时连接的可靠性也得倒了极大的提高。
如图3所示，开口223数量为多个，且沿固定段221的几何轴线对称设置。
具体地，通过沿固定段221的几何轴线对称设置多个开口223，使锁紧构件3能平衡稳定的对本实施例的端子组件2进行准确定位，通过将开口223对称设置，又确
保了开口223的一致性。
在本实施例中，开口223的数量为两个。
可选的，开口223形状为矩形。
在本实施例中，利用矩形对边平行、对边相等、四个角都是直角等便于加工制造的特点，将开口223的形状设计成矩形。
如图2所示，固定段221的侧壁开设至少一个钩孔224，连接器壳体1的侧壁还设置有弹性卡接件13，弹性卡接件13与钩孔224卡接。
具体地，弹性卡接件13例如可以为一端与连接器壳体1内壁连接的弹片，弹片的自由端在端子组件2装入后卡入固定段221的侧壁开设的钩孔224，钩孔224例如可以为通孔。根据具体情况，钩孔224可以设置多个，也可以将钩孔224设计成凹陷的槽。
在本实施例中，钩孔224的数量为1个。
锁紧构件3以及本申请提供的连接器的拆卸方法如下：使用薄片工具伸进开窗12的边缘，利用杠杆原理，将锁紧构件3撬起，此时锁紧构件3由固定位置退回到预装位置，再使用工具将弹性卡接件13勾起，然后向后拉拽端子组件2即可将端子组件2与连接器壳体1分离，最后将锁紧构件3卸下。
可选的，开口223对称布置在钩孔224两侧。
在本实施例中，为了避免锁止构件3插入开口223时与弹性卡接件13产生干涉，将开口223对称的布置在钩孔224的两侧。
如图5所示，锁止构件3包括锁紧本体31，以及自锁紧本体31两侧边向下竖直延伸的定位部32，锁紧本体31的外轮廓与开窗11的轮廓匹配，定位部32插入对应的开口223形成的空间内。
具体地，锁紧本体31的设置便于使用者在对锁止构件3进行插入以及插入完成后，对锁止构件3的水平度进行观察，防止锁止构件3发生倾斜，从而影响定位及固定效果，而且，由于锁止构件3一般为塑胶等具有弹性的材质，若在倾斜度较大的情况下强行插入，甚至会对TPA件造成不可逆的损坏。
在本实施例中，定位部32包括可插入开口223形成空间内的夹持部321，且夹持部321的夹持面为竖直设置的平面，沿夹持部321的下边缘还设置具有倾斜面的导向部322，用于引导定位部32插入开口223形成的空间内；沿夹持部321的上边缘还设置有弧形固定部323，弧形固定部323与固定段221的外表面匹配，当锁止构件3经由开窗12安装于连接器壳体1内，定位部32插入开口223形成的空间内后，弧
形固定部323与固定段221的外表面抵接；在弧形固定部323的中间还设有用于避让弹性卡接件13的避让空间325，避让空间325的宽度大于弹性卡接件13的宽度。
锁止构件3采用注塑一体成型。
可选的，在定位部32外壁的最下方还设有呈倒钩状的凸起324，连接器壳体1的侧壁至少设置有一个卡口14，凸起324与卡口14卡接。
具体地，定位部32还设有用于与连接器壳体1固定，防止定位部32插入连接器壳体1后脱落的凸起324，凸起324的形状呈倒钩状；在连接器壳体1的侧壁还开设至少一个与凸起324卡接的卡口14.
在本实施例中，卡口14为通孔，形状为矩形，卡口14的尺寸大于凸起324的尺寸。
在其他实施例中，凸起324也可以是其他形状的，例如矩形凸台，圆形凸台等。
可选的，定位部32的宽度小于等于开口223的宽度。
在本实施例中，为了保证定位部32能插入倒开口223形成的空间内，将定位部32的宽度设计呈小于等于开口223的宽度。
可选的，第一外导体21和/或第二外导体22的材质为磷青铜。
在本实施例中，将第一外导体21和/或第二外导体22的材质选为磷青铜，主要是注重磷青铜具有以下性能和用途：
磷青铜有更高的耐蚀性，耐磨损，冲击时不发生火花。用于中速、重载荷轴承，工作最高温度250℃。具有自动调心，对偏斜不敏感，轴承受力均匀承载力高，可同时受径向载荷，自润滑无需维护等特性。锡磷青铜是一种合金铜，具有良好的导电性能，不易发热、确保安全同时具备很强的抗疲劳性。锡磷青铜的插孔簧片硬连线电气结构，无铆钉连接或无摩擦触点，可保证接触良好，弹力好，拨插平稳。该合金具有优良机械加工性能及成屑性能，可迅速缩短零件加工时间等。
可选的，第一外导体和/或第二外导体的壁厚小于1mm。
具体地，为了保证端子的性能以及加工的工艺性，一般选用比较薄的板材制作，大多采用厚度小于1mm的板进行冲压成型，需要说明的是第一外导体和第二外导体可选用不同厚度的板。
在本实施例中，第一外导体和第二外导体均选用的厚度为0.4毫米的磷青铜。
虽然已经通过例子对本申请的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本申请的范围。本领域的技术人员应该理解，可在不脱离本申请的范围和精神的情况下，对以上实施例进
行修改。本申请的范围由所附权利要求来限定。
