Description

一种模块化连接器 技术领域
本发明涉及一种电气连接设备，尤其是一种具有新颖构造的模块化自短路连接器。
背景技术
模块化连接器是一种新式的连接器构造方式，其包括插芯模块，其中，插针端子被安装在公端插芯模块中，插孔端子被安装在母端插芯模块，公端插芯模块的塑壳和母端插芯模块的塑壳具有对配特征，以便安装到一起。取决于插芯模块的型号，单个的插芯模块可被制作为容纳特定数量和尺寸的端子。在构造连接器时，根据实际需要，在卡接框架内安装所需型号和数量的插芯模块，从而得到符合具体应用场景的连接器。
在某些电气连接场合，还要求连接器具有自短路功能以确保系统的安全性。具有自动短路功能的连接器通常被称为“自短路连接器”。自短路连接器根据使用要求可以分别自动实现短路与解除短路的功能，例如，配对的连接器在相互分离后，短路机构工作，使连接器中的接触件和壳体短接，即处于自短路状态；而连接器插合后，由短路机构造成的短路状态自动解除，恢复到正常连接状态。对于包含多个电接触件的多芯连接器，还要求其自短路构造能够实现相邻的端子之间的自动短路。
现有技术中，往往采用单独的短接结构(例如，弹性短接片)来连接相邻位的插接端子，实现自短路。在模块化连接器中，则缺乏实现自短路功能的设计特征。

具体实施方式
在以下的描述中，参考各实施例对本发明进行描述。然而，本领域的技术人员将认识到可在没有一个或多个特定细节的情况下或者与其它替换和/或附加方法、材料或组件一起实施各实施例。在其它情形中，未示出或未详细描述公知的结构、材料或操作以免使本发明的各实施例的诸方面晦涩。类似地，为了解释的目的，阐述了特定数量、材料和配置，以便提供对本发明的实施例的全面理解。然而，本发明可在没有特定细节的情况下实施。此外，应理解附图中示出的各实施例是说明性表示且不一定按比例绘制。
下面结合附图对本发明作进一步的说明。
图1是根据本发明的实施例的一种模块化自短路连接器的母端插芯模块30的示意图。图2是根据本发明的实施例的一种模块化自短路连接器的公端插芯模块40的示意图。图3是图1所示的母端插芯模块和图2所示的公端插芯模块的组装示意图。母端插芯模块30和公端插芯模块40具有结构上的对配关系，可以如图3所示地插接到一起。尽管图3中未示出所有细节，但是可以理解，通过将母端插芯模块30安装在母端连接器的卡接框架内，并将公端插芯模块40安装在公端连接器的卡接框架内，就可以得到对配的连接器套件100。
图4A是图1所示的母端插芯模块30的爆炸图。母端插芯模块30可包括母端插芯壳体301和盖子10，多个插孔端子20可安装在母端插芯壳体301的相应端子位中，还包括用于夹线的压线弹簧240和用于退线的推块250。结合图1－3和图4A，可以理解，母端插芯壳体301的下部可以插入公端插芯模块40的壳体中。
图4B是图2所示的公端插芯模块40的爆炸图。图6是图2所示的公端插芯模块40中的插针端子50的结构示意图。插针端子50可以插入插孔端子20的插接部220，形成对配连接。可以理解，图4B的公端插芯模块40的爆炸图在多个方面类似于图4A的母端插芯模块30的爆炸图，但是将插孔端子20替换为插针端子50，将母端插芯壳体301替换为公端插芯壳体401。
基于图1所示的母端插芯模块30，可以实现具有自短路功能的连接器，这种自短路功能至少部分地通过插孔端子20的特定构造来实现。图5A是图1所示 的母端插芯模块中的插孔端子的结构示意图，示例性地展示了这种特定构造的细节。具体而言，图5A所示的插孔端子20可以是金属片材经多次折弯加工后的结构，其包括接线基部210和插接部220，接线基部210和插接部220是相连接的结构。图5A中，插接部220被构造为沿着插孔端子的插接方向(进线方向)延伸。接线基部210被构造为由基片211和位于其两端的第一壁212和第二壁213形成的框体。一个边腿结构230和位于基片211一端的第一壁212连接，并从该第一壁212延伸出。边腿结构230的延伸方向和插接部220的延伸方向大致并行，即沿着插接端子的插接方向延伸。图5B是图1所示的母端插芯模块30中插孔端子20、压线弹簧240和推块250的关系示意图。结合图4A和5B可以理解，压线弹簧240的回复力可夹紧位于接线基部210的空间内的导线。在需要退线时，以工具向下推动推块250，进而使压线弹簧240变形，解除压线弹簧24的夹线臂对导线的锁定。
如图5A所示，边腿结构230被优选地构造为一种弹性臂结构。这种弹性臂的弹性有利于形成可靠的电接触。边腿结构230可大致为狭长金属片，且该金属片的表面和基片211的表面基本上垂直。在边腿结构230的末端形成一个短接弧部235，该短接弧部235在结构上被构造为沿一段弧线逐步地远离插接部220，然后再返回，形成一个尾勾236。即，短接弧部235沿着边腿结构230的延伸方向(插接端子的插接方向)同插接部220的轴线的间距先逐步增大，然后又逐渐缩小。
为了让边腿结构230充分实现自短路功能，边腿结构230的末端同插接部220的轴线的最大间距大于所述第一壁212同插接部220的轴线的间距。这使得边腿结构230的末端在空间上比接线基部210的框体更加远离插接部220的轴线，这有利于一个插孔端子20的边腿结构230的末端和另一个空间对称放置的插孔端子20的边腿结构230发生电接触。
图8A是根据本发明的实施例的公端插芯模块40和母端插芯模块30对配但未插接到位时的截面图。图8B是根据本发明的实施例的公端插芯模块40和母端插芯模块30对配且插接到位时的截面图。结合图8A和图8B，可以理解，插孔端子20的插接部220插入在母端插芯壳体301的各端子孔位内，而边腿结构230位于母端插芯壳体301的端子孔位外。
比较图8A和图8B，可以看出，当公端插芯模块40和母端插芯模块30未插接到位时，位置相邻的两个插孔端子的边腿结构230A和230B发生电接触，实现自短路。而当公端插芯模块40和母端插芯模块30对配且插接到位时，公端 插芯模块40中的绝缘隔挡410进入到位置相邻的两个插孔端子的边腿结构230A和230B之间，使得二者之间的电连接被解除，即解除自短路状态。
公端插芯模块40中的绝缘隔挡410被更为详细地显示在图2和图7中，母端插芯模块30上的对配结构被更为详细地显示在图1。如图2所示，绝缘隔挡410位于母端插芯模块40的端子插接面，其延伸方向和插针端子50的延伸方向一致。如图1所示，在公端插芯模块30的端子插接面上，设有和绝缘隔挡410对配的接纳孔310。接纳孔310可具有和绝缘隔挡410的形状匹配的横截面，例如，实施例中所示的“工”字形横截面。可以理解，基于绝缘隔挡410和接纳孔310的位置及形状方面的对配关系，当母端插芯模块30和公端插芯模块40对配安装在一起时，绝缘隔挡410会穿过接纳孔310。
如图1和图2所示，在具有三对插针端子50和三对插孔端子20的实施例中，绝缘隔挡410的数量为三，即，绝缘隔挡410的数量和插接端子对的数量对应。然而，应理解，本发明不限于此，根据需要，亦可为多对插接端子统一设置一个绝缘隔挡410。
如图7所示，绝缘隔挡410包括一对侧支撑壁411和412，并包括在该对侧支撑壁之间延伸的横隔片413。横隔片413被制作为高于侧支撑壁411和412，且在横隔片413的顶部形成有插入引导部414。插入引导部414的形状有利于使其被插入到位置相邻的两个插孔端子20的边腿230A和230B中。例如，插入引导部414的形状可为相互距离逐步减小并最终相交的一对斜面。此外，如图7所示，插入引导部414在其中部具有弧形收缩段415，此形状更好地配合插接部220的边腿结构230上的短接弧部235，减少插入阻力。
在基于图1－图7所描述的实施例中，边腿结构230是插孔端子20的一部分，绝缘隔挡410形成在公端插芯模块40中。可以理解的是，也可以将边腿结构形成为插针端子50的一部分，并在母端插芯模块30中形成绝缘隔挡。
上文已对基本概念做了描述，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。
