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自短路连接器。
背景技术
在某些电气连接场合，要求连接器具有自短路功能以增强系统的安全性。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，换言之，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；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。
自短路连接器的分类及特点按照连接器电接触件数量的多少可以分为单芯自短路连接器及多芯自短路连接器。多芯自短路连接器的自短路构造不但要实现接触件与外壳之间的自动短路，还要实现接触件与接触件之间的自动短路。

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自短路连接器的示意图。具体而言，图1示出连接器组件，其包括可彼此插接在一起的自短路连接器100和对配连接器200。自短路连接器100可包括盖子10、多个插接端子20、绝缘芯体30以及跨接短路片80。对配连接器200包括对配绝缘芯体40以及多个对配插接端子50。尽管未示出，但可以理解，插接端子20可被放置到绝缘芯体30内的对应端子孔位中，对配插接端子50可被放置到对配绝缘芯体40内的对应端子孔位中。
图1的实施例中，插接端子20被示出为插孔端子，对配插接端子50被示出为插针端子。当绝缘芯体30和对配绝缘芯体40相互之间对插到位时，插孔端子和插针端子插接在一起形成电连接。
图1的实施例中，自短路连接器100的自短路功能至少部分地通过插接端子20的特定构造来实现。图2是图1所示的自短路连接器100中的插接端子20的示意图，示例性地展示了这种特定构造的细节。具体而言，图2所示的插接端子20可以是单片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2中，插接部220被构造为沿着插接端子的插接方向(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。
如图2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，这有利于一个插接端子20的边腿结构230的末端和另一个空间对称放置的插接端子20的边腿结构发生电接触。
尽管图中未示出，但可以理解的是，插接端子20的插接部220用来插入绝缘芯体30的各端子孔位内，而所述边腿结构230位于绝缘芯体30的端子孔位外。
图1中的盖子10能够用于固定插接端子20的接线基部210，并隔断相邻位的电气连接。
图3是显示多个插接端子以及跨接短路片的位置结构关系的示意图。图3所示，当4个插接端子20安装就位时，空间对称地放置的两个插接端子20A和20B构成一个插接端子对，空间对称地放置的插接端子20C和20D构成另一个插接端子对。本申请中，如未作其他说明，将图3所示的插接端子20A和20B的空间位置关系称为位置相对，将图3所示的插接端子20A和20C的空间位置关系叫作位置相邻。
对于组成一个插接端子对的两个插接端子，例如插入绝缘芯体30的端子孔位内的位置相对的插接端子20A和20B，当自短路连接器100没有和对配连接器200对插到位时，插接端子20A的边腿结构230A同插接端子20B的边腿结构230B发生接触，从而实现两位自短路。可以理解，位置相对的插接端子20A和20B之间只需一个接触点，即边腿结构230A和230B的接触点，就实现了自短路所需的电接触。这使得两位自短路的接触电阻大为减小。
某些场合下，需要实现多位自短路，因此需要使用跨多位的跨接短路结构。本发明由于为插接端子采用了边腿结构，因此跨多位的跨接短路得以大大简化。例如，图3显示了基于跨接短路片80的多位自短路。跨接短路片80被构造为片状，其带有卡钩以便于装入绝缘芯体30。图3所示的四位跨接短路片80被装入绝缘芯体30中，并和两个插接端子对的所有插接端子20A、20B、20C、20D形成电连接。 根据多位自短路的具体需要，跨接短路片80可以被构造为跨接六位、八位等。
图4是图3所示结构的横截面图，图5是图3所示结构的仰视图，图4和图5展示了跨接短路片80和边腿结构230A和230B的接触情况。
结合图2－图5，可以理解，通过采用本发明的插接端子，进线、插接和两位自短路的功能由一个金属件来完成，这简化了金属件的组成和结构。同时，由于金属件的减少，绝缘芯体的构造也相应得到了简化。
图6是图1中对配插针端子50的视图。可以理解，在一个变型例中，可在如图6所示的插针端子上形成如图2所示的一体的边腿结构，并将这种带有边腿结构的插针端子用于自短路连接器。
图7是图1所示的自短路连接器和对配连接器插接状态的截面图。在对配连接器200的对配绝缘芯体40中，设有绝缘隔板510。当自短路连接器100和对配连接器200插接就位时，绝缘隔板510介入到位置相对的两个插接端子的边腿结构中间，从而将边腿结构的电连接断开。绝缘隔板510顶部还设有凹槽，当自短路连接器100和对配连接器200插接到位时，跨接短路片80局部插入该凹槽，从而使跨接短路片80和插接端子的边腿结构实现电隔离。
图8显示图2所示的插接端子的接线方式。压线弹簧240被装在接线基部210的接线框上，构成一个直插式接线结构。推块250可被用于向下推动压线弹簧240的夹线臂，实现退线(某些应用场合也用于进线)。
尽管以图1所示的连接器为例描述了本发明，但可以理解，本发明所提出的插接端子的构造能够应用于包含两位自短路和多位自短路应用的各种连接器。
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。
