一种外导体结构
相关申请
本申请要求于2022年12月26日递交的申请号为202223474330.3的中国专利申请的优先权，并引用上述专利申请公开的内容作为本申请的一部分。
技术领域
本申请涉及连接器外导体技术领域，尤其涉及一种外导体结构。
背景技术
目前，连接器的外导体结构一般有以下两种形式：第一种形式为，在外导体基体的前端延伸设置有若干接触弹簧片，通过接触弹簧片上突出设置的凸点与配合连接器配合连接，实现机械和电气连接，这种设置方式在多次插拔后，容易出现连接不牢靠的问题，对连接器的稳定性会造成很大的影响；第二种形式为，进一步在若干接触弹簧片的前端延伸形成一连接部，通过连接部来防止外导体结构在多次插拔后，容易出现连接不牢靠的问题，但是，该种设置方式由于连接部的存在，难免会造成外导体结构在插拔时，插拔力较大的问题，不便于使用，甚至有可能在插拔时，会对连接器内部的结构造成破坏，为了解决这一问题，本领域技术人员将部分接触弹簧片设置为未与连接部连接的悬臂状，在满足连接牢靠的前提下，能够明显的降低外导体结构的插拔力，但是，由于悬臂状结构的头部没有支撑，在物料转运过程中，或者在使用过程中易发生变形，导致悬臂状结构的头部容易向外张开，进而导致无法与配合连接器进行装配，影响外导体结构的使用。
发明内容
有鉴于此，本申请的目的是提供一种外导体结构，以解决背景技术中提到的技术问题。
为了达到上述目的，本申请所采用的技术方案是：一种外导体结构，包括外导体基体以及设置在外导体基体一侧的连接部，外导体基体与连接部之间通过至少一对连接臂相连，连接部上朝外导体基体所在的方向延伸形成有至少一对悬臂。
在优选的实施方式中，连接臂和悬臂均设置有多对，且多对连接臂和悬臂沿连接部的周向交错设置。
在优选的实施方式中，连接部呈环状，且连接部、外导体基体以及由至少一对连接臂和至少一对悬臂所限定的筒状结构三者间同轴线设置。
在优选的实施方式中，连接部的横截面为圆形、椭圆形、具有倒角或倒圆的多边形中的任意一种。
在优选的实施方式中，连接臂和/或悬臂上向外弯折形成用于电气连接的凸点。
在优选的实施方式中，凸点呈拱形，凸点的最高处形成接触区域。
在优选的实施方式中，在悬臂上，接触区域与连接部之间的距离占悬臂总长度的1/4～2/3。
在优选的实施方式中，外导体结构由一金属板材一体冲压并弯折而成，金属板材相对的两端形成接合槽。
在优选的实施方式中，连接臂沿周向的最大宽度不大于悬臂沿周向的最大宽度。
在优选的实施方式中，所有的悬臂和连接臂沿周向的宽度之和不大于连接部总周长的70％。
与现有技术相比，本申请的有益效果是：本申请在外导体基体与连接部之间通过至少一对连接臂相连，并在连接部上朝外导体基体所在的方向延伸形成有至少一对悬臂，即使在物料转运过程中，或者在使用过程中发生变形，导致悬臂的头部向外张开，也不影响悬臂插入配合连接器，同时，变形的悬臂在装入配合连接器的过程中，会与配合连接器的外导体内壁发生挤压，使变形的悬臂恢复原状，提升了装配效率；而且，本申请的外导体结构对制造精度的要求相对较低，降低了零件的加工难度，提高了生产效率。

具体实施方式
现在将参照附图来详细描述本申请的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、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。
本申请的设计原理如下：为了解决由于悬臂状结构的头部没有支撑，在物料转运过程中，或者在使用过程中易发生变形，导致悬臂状结构的头部容易向外张开，进而导致无法与配合连接器进行装配，影响外导体结构的使用的问题，本申请将悬臂状结构由原来连接至外导体基体，调整为连接至连接部，具体技术方案如下：
一种外导体结构，如图1和图2所示，包括外导体基体10以及设置在外导体基体10一侧的连接部20，外导体基体10与连接部20之间通过至少一对连接臂30相连，连接部20上朝外导体基体10所在的方向延伸形成有至少一对悬臂40。本申请的外导体结构，即使在物料转运过程中，或者在使用过程中发生变形，导致悬臂40的头部向外张开，也不影响悬臂40插入配合连接器70，同时，请参阅图3，变形的悬臂40在装入配合连接器70的过程中，会与配合连接器70的外导体内壁发生挤压，使变形的悬臂40恢复原状，提升了装配效率；而且，本申请的外导体结构对制造精度的要求相对较低，降低了零件的加工难度，提高了生产效率。
在一实施方式中，如图1所示，连接臂30和悬臂40均设置有多对，且多对连接臂30和悬臂40沿连接部20的周向交错设置。将连接臂30和悬臂40均设置有多对，一方面可以提升外导体结构与配合连接器70连接时的稳定性，另一方面，间隔与交错设置具有很好的美观 性，并具有良好的机械和电气性能。
在一实施方式中，连接部20呈环状，且连接部20、外导体基体10以及由至少一对连接臂30和至少一对悬臂40所限定的筒状结构三者间同轴线设置。进一步的，连接部20的横截面为圆形、椭圆形、具有倒角或倒圆的多边形中的任意一种，本领域技术人员在使用时，可根据连接器的类型不同，选择具有相应形状的外导体结构。
在一实施方式中，连接臂30和/或悬臂40上向外弯折形成用于电气连接的凸点50，本实施例中，优先在连接臂30和悬臂40上均向外弯折形成用于电气连接的凸点50，当本申请的外导体结构插入配合连接器70时，连接臂30和悬臂40上设置的凸点50沿径向向内形变并与配合连接器70形成稳定的机械和电气连接，实现信号的传输，图3为外导体结构与配合连接器70的装配示意图。
在一实施方式中，如图1所示，凸点50呈拱形，凸点50的最高处形成接触区域501，当本申请的外导体结构插入配合连接器70之后，接触区域501与配合连接器70的外导体内壁紧密接触，接触区域501优先设置为弧形面，以实现稳定的信号传输功能。
进一步的，悬臂上接触区域501与连接部20之间的距离占悬臂40总长度的1/4～2/3，优先为占比1/2左右，此处，由于杠杆原理，若接触区域501设置的太靠前，则容易出现插拔力大，及装配困难的问题；若设置的太靠后，则装配后配合连接器70对悬臂40与连接部20的连接处施加的压力过大，容易导致悬臂40在拔出后无法完全复位，影响使用。
此外，连接臂30和悬臂40上设置的接触区域501可以分布在同一个圆周面上，当然也可以使两者在本申请外导体结构的轴向上偏移预定的距离，以进一步较小其插入配合连接器70时的插拔力。
当然，为了进一步优化本申请的插拔力，还可以采取以下措施：
(1)连接臂30沿周向的最大宽度不大于悬臂40沿周向的最大宽度，考虑到美观性及布局的合理性，一般情况下，连接臂30和悬臂40的沿周向的宽度是基本一致的，然后，为了调节外导体结构整体的插拔力，会在连接臂30上进行一定的调整，比如适当削减连接臂30整体或局部位置处沿周向的宽度，以调整其插拔力，达到优化其使用体验的目的，所以，连接臂30沿周向的最大宽度一般是不大于悬臂40沿周向的最大宽度的；
(2)所有的悬臂40和连接臂30沿周向的宽度之和不大于连接部20总周长的70％，经试验证明，若大于70％，则会出现难以插拔的情况，影响其正常使用。
在一实施方式中，外导体结构由一金属板材一体冲压并弯折而成，金属板材相对的两端形成接合槽60，为了提升外导体结构弯折后的强度，可以将接合槽60设置为相互配合的燕 尾槽，冲压式结构的设置，可明显降低外导体接触元件的制造成本。
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。
