Description

具有插针固定结构的连接器壳体 技术领域
本发明涉及电气连接技术领域，并且更具体地，涉及一种具有改进的插针固定结构的连接器壳体。
背景技术
电连接器(electric connector)被广泛应用于各种工业领域，例如汽车电子电气架构中的车辆连接器，以及光伏发电系统的储能连接器。
电连接器通常包括塑料外壳体以及安装于壳体内的端子。端子插入壳体后，前后两端分别通过适当的接线技术与其它导体构成电连接(例如，端子前端和对配端子插接，端子后端与导线压接或以螺栓方式连接)。图1A显示了一款用于容纳插针端子的插座连接器完成接线后的状态，其中，插针端子110用于从插座连接器100的后端插入连接器的塑壳中，然后插座连接器100的前端可以和对配连接器(未示出)插接在一起。图1B从另一视角显示了图1A中的插座连接器。
图2示出的一款插针端子110可用于图1A所示的应用中。结合图1A的外部视图、图1D的截面图、以及图2的插针端子，插针端子110包括插入插座连接器100的前端部112，以及留在插座连接器100外部的尾端部116。尾端部116可为扁平状，并设有螺纹孔118，进而可以通过螺栓120等紧固元件将铜牌或其它带有螺纹孔的导体连接到插座端子110的尾端。插针端子110的前端部112可分为三段，依次是定位凸台113，卡装段114，以及插接头段115。定位凸台113用于和插座连接器100的壳体结构配合，提供基本的定位。卡装段114可设有环状的卡槽1141，用于和下文结合图1C所介绍的弹性卡扣配合。圆柱状的插接头段115位于末端，用于和对配连接器中的对配端子建立电连接。
图1C显示了这款插座连接器100的前端(即和插针端子的插入端相对的另一端)的视图。如图1C所示，插座连接器100的用于容纳插针端子110的腔体内，有六片沿周向等距分布的弹性卡扣130。图1D显示插座连接器沿图1C中的A-A截面的截面图，图1E显示图1D中方框所示局部的放大图。如图1D和图1E所示， 弹性卡扣130是一种从插座连接器100的腔体内壁延伸而出的悬臂结构，这种悬臂大体轴向地延伸，其自由末端包括径向地朝内凸起的卡接凸起135，该卡接凸起135用于卡入插针端子上的卡槽结构1141内，从而起到固定插针端子110的作用。
进一步如图1E所示，插针端子110和插座连接器100的腔体产生物理连接的段分为刚性配合段151以及弹性配合段152：刚性配合段由插座连接器100尾端的端子后插孔的深度来限定，插针端子110的本体在整个厚度范围内和端子后插孔的内壁紧密接触；弹性配合段152则是插针端子110的本体和弹性卡扣130发生接触的段，该段基本可由弹性卡扣130在轴向上的延伸长度来限定。刚性配合段151的长度加上弹性配合段152的长度，就是插针端子与连接器壳体间总的配合长度。例如，刚性配合段长度为7.8mm，弹性配合段长度为6.3mm，则总的配合长度为14.1mm。
在实际应用中，通过扭力工具转动图1A所示的螺栓120，从而实现接线操作。但是，在使用扭力工具的过程中，由于工具所施加的力量的传递，可能带动插针端子110在壳体内晃动，而弹性卡扣130会随着插针的晃动而变形。弹性卡扣130变形后，会减少卡扣与插针间的干涉量，从而增加插针脱落的风险。此外，因插针端子110在安装过程中晃动较大，会影响加载扭矩的精准性，从而影响电连接的可靠性。
因此，希望能开发一种连接器壳体，其具有改进的插针固定结构，从而改善因插针端子在插孔内的晃动而造成的失效风险。

下面结合附图对本发明作进一步的说明。
首先参考图3－图5，描述本发明的第一实施例。如图3所示，插座连接器壳体300包括一个两端开口的腔体以用于容纳插针端子，例如，如图2所示的插针端子110。插针端子110可以从插座连接器壳体300的尾端插入，并且使其插接头段115穿过端子通道301。端子通道301中设有环形台阶350，其用于和所述插针端子的定位凸台113形成物理干涉以限定所述插针端子110的插入行程的末端。沿端子通道301的圆周分布有四个弹性卡扣330，其自环形台阶350轴向向内延伸，用于和插针端子110上的卡装段114配合。除了弹性卡扣330，相邻的弹性卡扣之间还设有刚性筋条340，其同样其自环形台阶350轴向向内延伸，用于提供和插接端子的物理接触和定位。沿端子通道301的轴向，刚性筋条340的高度大于弹性卡扣330的高度。
图4显示了图3所示的插座连接器壳体300的前端(即，和插入插针的尾端相对的一侧)的视图，通过该视图，可以看到弹性卡扣330和刚性筋条340沿端子通道301的圆周周向的分布情况。每个弹性卡扣330之间间隔90度，且每个刚性筋条340之间间隔90度。如图3所示，弹性卡扣330具有悬臂结构，这种悬臂大体轴向地延伸，并且在弹性卡扣的自由末端设有沿径向朝内凸起的卡接凸起335，该卡接凸起335用于卡入插针端子110上的卡槽结构内，从而起到固定插针端子的作用。结合图3，弹性卡扣330的内壁(不含其末端的卡接凸起部分)和刚性筋条340的内壁是共圆周的，即它们到端子通道301的轴线的径向距离相等。
进一步结合图5，通过在插座连接器壳体300内设置如图3和图4所示的插针固定结构，当向插座连接器壳体300内插入如图2所示的端子插针110时，四个弹性卡扣330上的卡接凸起335卡入插针端子110上的卡装段114的卡槽结构1141内，同时，刚性筋条340的内壁亦和插针端子110物理相邻，从而增加了插针端子 110和插座连接器壳体300的刚性配合长度。
进一步与图1D所示的情况相比，刚性配合长度在端子后插孔的深度基础上，进一步延长到刚性筋条340的末端，例如，相比图1E所示的现有产品的7.8mm的刚性配合长度(图5中的D1)，图3和图4的设计在不动其他配合零件设计及插座的外轮廓尺寸的条件下，将端子插针的刚性配合长度抬高至14.9mm(图5中的D2)。由于在端子通道301的轴向上，弹性卡扣330的长度与刚性配合长度D2至少部分地重合，因此刚性配合和柔性配合被组合施加于插针端子110的前端部，借助于这种方式，能抑制插针端子的晃动，这可体现为在插针端子110与插座连接器壳体300间的配合间隙相同的情况下，减小插针端子与壳体间的最大偏摆角度。
在可选实施例中，刚性筋条340在高度上可以超过弹性卡扣330，因此在客户端安装过程中能进一步防止或抑制弹性卡扣的变形，从而降低弹性卡扣变形带来的脱针风险。
上述实施例中，关于插接端子和刚性筋条的细节仅作为示例。作为可行的变化例，在插针端子的插入深度上，所述刚性筋条轴向延伸所达的位置超过弹性卡扣与插针端子发生卡接的位置即可。
上述实施例中，“刚性筋条”或“筋条”理解为指筋条结构不同于弹性卡扣的悬臂结构，因而不似弹性卡扣一般具有易于弹性形变的物理性质。因此，其“刚性”应广泛理解为各种强于悬臂结构的结构刚性，而非绝对的刚性。
上述实施例中，使用了如图2所示的插针端子110，且使用了如图4所示的具有四个弹性卡扣330和四个刚性筋条340的插座连接器壳体300。可以理解，插针端子不限于图2所示的构造，而是可以采取任何具有同弹性卡扣相配合的卡装段的端子；也可以理解，插座连接器壳体的插针固定结构不限于四个弹性卡扣和四个刚性筋条，而是可以为任何复数数量的弹性卡扣和刚性筋条，例如，两个弹性卡扣和两个刚性筋条。某些变化例中，弹性卡扣和刚性筋条的数量可不相同，例如，四个弹性卡扣和两个刚性筋条；进一步，连接器壳体不限于插座连接器壳体，而是可以为任何合适类型，用于容纳插针端子(因此需要端子稳定结构)的连接器壳体。
上述实施例中，对于弹性卡扣的使用仅是本发明的具体实例，可理解，数个弹性卡扣可被合理引申为沿所述端子通道周向分布的数个柔性定位件，这种柔性定位件用于和所述插针端子发生弹性卡接。同样，对于刚性筋条的使用仅是本发明的具体实例，可理解，数个刚性筋条可被合理引申为沿所述端子通道周向分布的数个刚性定位件，这种刚性定位件用于和插针端子在端子通道轴向的第一预定长度内相 互抵接。在端子通道的轴向上，柔性定位件的长度与第一预定长度至少部分地重合，因此刚性配合和柔性配合被组合施加于插针端子的前端部。通过这种方式，能够更好抑制插针端子的晃动，减小插针端子与壳体间的最大偏摆角度；进一步，通过将插针端子和柔性定位件发生卡接的位置设置于该第一预定长度内，刚性定位件进一步有效限制了插针端子的摆动。
上文已对本发明的基本概念做了描述。显然，对于本领域技术人员来说，上述披露仅仅作为示例，而并不构成对本申请的限定。虽然此处并没有明确说明，本领域技术人员可能会对本申请进行各种修改、改进和修正。该类修改、改进和修正在本申请中被建议，所以该类修改、改进、修正仍属于本申请实施例的精神和范围。
