本发明要解决的一个技术问题是提供一种结构设计简单，安装方便、母座端子相对于芯轴可以进行自动导正、且芯轴拔出后母座盖子可以进行自动回位的浮动式母座。
本发明要解决的另一个技术问题是提供一种包括上述具有自回位功能浮动式母座的同轴连接器。
为了解决上述技术问题，本发明涉及了一种具有自回位功能的浮动 式母座，包括母座绝缘体、相对于该母座绝缘体进行浮动的母座盖子、母座端子以及包裹于上述母座绝缘体外围的屏蔽壳体。母座盖子套设、固定于母座端子。另外，还包括弹性导向板，其数量设置为2件，分别由上述屏蔽壳体的左、右侧壁向上延伸而成。每个弹性导向板均包括弹性侧顶部和弧形导向部，其中，弹性侧顶部用来顶靠母座盖子，其由弹性导向板的内壁向内延伸而成。弧形导向部由弹性导向板自由端向外弯曲延伸而成。当同轴连接器公座相对于同轴连接器母座进行插拔后，母座盖子在弹性侧顶部的作用下相对于母座绝缘体可以沿X方向和/或Y方向上的位置微调、归正，从而使得母座盖子以及母座端子具有正确的相对位置，为同轴连接器公座的下次插装操作做好准备。
作为上述技术方案的进一步改进，弹性侧顶部呈S形，且其相背于母座盖子的侧壁进行外延。
作为上述技术方案的进一步改进，屏蔽壳体的前、后侧壁向上延伸有向内弯曲的弹性上顶部，用来弹性顶靠公座外壳体。
作为上述技术方案的更进一步改进，弹性上顶部的数量设置为4个，沿屏蔽壳体的中轴线进行周向均布。
作为上述技术方案的进一步改进，所述母座端子包括导通部、设置于该导通部左、右侧的插装部以及固定于该导通部正下方的弹性支撑部。弹性支撑部固定于母座绝缘体的空腔内。母座盖子扣盖于导通部的正上方、且其内腔设置有与插装部相适配的插槽。另外，该母座盖子完全与上述母座绝缘体不进行接触，仅通过母座端子进行支撑。当同轴连接器公座相对于同轴连接器母座进行插装时，借助于弹性支撑部母座盖子相对于母座绝缘体可以进行沿X方向、Y方向和/或Z方向上的位置微调，从而使得公座端子相对于导通部具有正确的插接位置。
作为上述技术方案的更进一步改进，弹性支撑部由前连接体和后连接体构成，其中，上述前连接体包括由导通部的前侧壁向下延伸而成前多弯弹性段以及沿该前多弯弹性段的下端部水平前延、插设于母座绝缘体前侧壁的前固定段。上述后连接体包括由所述导通部的后侧壁向下延 伸而成后多弯弹性段以及沿该后多弯弹性段的下端部水平后延、插设于母座绝缘体后侧壁的后固定段。
作为上述技术方案的更进一步改进，前多弯弹性段和后多弯弹性段均呈S形，且两者的延伸方向相反。
作为上述技术方案的进一步改进，在母座盖子设置有限位块，其数量设置为2件，且分别由母座盖子的底壁沿左、右方向外延而成。
作为上述技术方案的进一步改进，在屏蔽壳体的左、右侧壁上均设置有卡刺，相对应的，在母座绝缘体的左、右侧壁上开设有与上述卡刺相适配的卡槽。
另外，本发明还公开了一种同轴连接器，其包括相互对插的公座和母座，且该母座为上述的具有自回位功能的浮动式母座。
通过采用上述技术方案进行设置，母座盖子可以进行自适应性位移调整，直至公座芯轴相对于母座端子具有正确的装配位置，从而杜绝了刚性装配而导致的插装配合件受损，进而影响信号传输稳定性情况的发生。更为重要的，当公座芯轴被拔出后，母座盖子在弹性侧顶部的顶靠力作用下进行自动回位，进而相应地带动母座端子进行回位，使得其相对于公座芯轴的位置偏移量控制在合理范围值以内，有利于公座芯轴下次插装操作的进行。

具体实施方式

下面结合具体实施例，对本发明的内容做进一步的详细说明，图1示出了本发明中同轴连接器的装配示意图，公座1插设于母座2内，且 其芯轴始终紧靠于母座端子23，从而以实现对电源或信号的传输。
为了使得同轴连接器具有优良的电源或信号传输性能，在本发明所公开的技术方案中应用了浮动式母座，其详细结构以及动作原理如下所述：图2、图3均示出了本发明中浮动式母座的立体图，其包括母座绝缘体21、母座盖子22、母座端子23以及屏蔽壳体24。其中，母座绝缘体21呈空腔结构(如图4中所示)。屏蔽壳体24为钣金结构，包裹于上述母座绝缘体21的外围。母座盖子22套设、固定于母座端子23上，且可以相对于母座绝缘体21进行浮动。母座盖子套设、固定于母座端子。母座端子23由导通部231、插装部232以及弹性支撑部233等几部分构成，插装部233设置于导通部231的左、右两侧；弹性支撑部233固定于导通部231正下方(如图7中所示)，从而使得导通部231在受到外力作用时自身处于可浮动状态。母座盖子22扣盖于导通部231的正上方、且其内腔设置有与插装部232相适配的插槽221(如图5、6中所示)。在此需要着重说明的是，母座盖子22完全与母座绝缘体21不进行接触，其仅通过母座端子23进行支撑。
浮动式母座的动作原理如下：当同轴连接器公座1与同轴连接器母座2进行插装时，固定于公座1上的芯轴施力于母座端子23，而与此同时，弹性支撑部233发生自适应性形变或倾斜，进而使得母座盖子22可以进行沿X方向、Y方向和/或Z方向上的位置微调，从而使得芯轴相对于母座端子23的导通部231具有正确的插接位置。这样一来，有效地杜绝了刚性装配而导致的同轴连接器配合件受损，进而影响信号传输稳定性情况的发生。另外，还可以在一定程度上消除振动、冲击等对同轴连接器连接可靠性造成的影响。
为了实现母座盖子22以及母座端子23的自回位动作，上述浮动式母座2还需要增设弹性导向板241，其数量设置为2件，分别由上述屏蔽壳体24的左、右侧壁向上延伸而成。每个弹性导向板241均包括弹性侧顶部2411和弧形导向部2412，其中，弹性侧顶部2411用来顶靠母座盖子22，其由弹性导向板241的内壁向内延伸而成。弧形导向部2412 由弹性导向板241的自由端向外弯曲延伸而成。当同轴连接器公座1相对于同轴连接器母座2进行插拔后，弹性导向板241直接顶靠于母座盖子22的侧壁，从而使得母座盖子22在侧向推力的作用下相对于母座绝缘体21可以沿X方向和/或Y方向上的位置微调、归正，进而使得母座盖子22以及母座端子23具有正确的相对位置，为同轴连接器公座1的下次插装操作做好准备。
作为上述浮动式母座2的进一步优化，上述弹性侧顶部2411优选为S形，且其相背于母座盖子22的侧壁进行外延，从而使得其具有良好的弹性性能，在实际工作过程中，使得母座盖子22的回位动作更加及时、准确。
再者，还可以屏蔽壳体24的前、后侧壁向上延伸有向内弯曲的弹性上顶部242，用来弹性顶靠公座1的外壳体，这样一来，一方面，使得公座1相对于母座2始终处于弹性压靠状态，避免两者发生刚性碰撞；另一方面，使得芯轴相对于母座端子23具有良好的接触稳定性。作为更进一步的优选，弹性上顶部242的数量设置为4个，沿屏蔽壳体24的中轴线进行周向均布。
为了使得上述弹性支撑部233具有较好结构强度以及动作灵敏性，作为上述浮动式母座的进一步优化，上述弹性支撑部233优选由前连接体2331和后连接体2332构成。具体为：上述前连接体233包括由导通部231的前侧壁向下延伸而成的前多弯弹性段23311以及沿该前多弯弹性段23311的下端部水平前延、插设于母座绝缘体21前侧壁的前固定段23312。后连接体2332类比于前连接体2331进行设置，其亦包括后多弯弹性段和后固定段(如图8中所示)。
作为更进一步的优化，前多弯弹性段23311和后多弯弹性段均呈S形。已知，S形构件在受到外力挤压或拉伸时，具有较大的弹性变形量，如此一来，通过芯轴施加一个较小的力即可使得弹性支撑部233的位置得到改变，提高了母座端子23在支撑浮动动作时的灵活性。
在此需要着重说明的是，前多弯弹性段2331设置为正向S形，而相 应地，后多弯弹性段优选为反向S形，这样一来，当母座端子23执行浮动动作时，在相同时刻，前多弯弹性段2331和后多弯弹性段分别承受反向力的作用，即：当前多弯弹性段2331承受拉伸力，而后多弯弹性段承受压缩力；亦或是当前多弯弹性段2331承受压缩力，而后多弯弹性段承拉伸力，这样一来，使得母座端子23的自适应位置调整过程更加平稳，另外，更为重要的是，当芯轴拔出母座端子23时，母座端子23可以在前多弯弹性段2331和后多弯弹性段的共同作用下进行自动回位动作，为下次公座1的插装操作做好准确。
再者，还可以在母座盖子22上设置限位块222，且数量优选设置为2件，且分别由母座盖子22的底壁沿左、右方向外延而成(如图6中所示)，这样一来，从而杜绝了由于公座1的下插力过大而导致母座端子23受损情况的发生(即母座端子23的弹性支撑部233受到下插力过大时，其自身会产生过大变形量，进而导致其自身失去弹性)。
再者，出于提高屏蔽壳体24与母座绝缘体21连接强度以及拆卸便捷性的方面考虑，还可以在屏蔽壳体24的左、右侧壁上均设置有卡刺243(如图9中所示)，相对应的，在母座绝缘体21的左、右侧壁上开设有与上述卡刺243相适配的卡槽211(如图4中所示)。
最后，在实际执行公座1插入母座2的过程中发现，当芯轴的倾斜角度超过一定范围时，母座端子23的自身稳定性会急剧下降，影响浮动效果，为此，还可以在两个弹性导向板241上均设置有压形限位凸起2413，其中，针对于单个弹性导向板241来说，压形限位凸起2413的数量不少于2个，且沿着上述弧形导向部2412的前后方向进行均布(如图10中所示)。这样一来，压形限位凸起2413的存在可以有效地控制公座1相对于母座2的插入角度，提高母座端子23在浮动过程的稳定性。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本 文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
