具体实施方式
现在将详细参考实施例，这些实施例的示例在附图中示出。在以下详细说明中，阐述了许多具体细节以便提供对各种描述的实施例的透彻理解。然而，对于本领域普通技术人员显而易见的是，可以在没有这些具体细节的情况下实践各种描述的实施例。在其它情况下，没有详细描述众所周知的方法、过程、部件、电路以及网络，以免不必要地模糊实施例的各方面。
本文提出的是一种密封的电连接器组件，其适合于坚固、可靠且安全地承载大于200安培的电流。
附图的图1和图2示出了在下文中被称为组件10的连接器组件的实施例，该连接器组件10包括阴型连接器主体12和限定头部(插头)护罩(在下文中被称为护罩16)的阳型连接器主体14，护罩16被构造成接纳阴型连接器主体12的向前部分18。如本文中所使用的，如图3A和3B所示，“向前”指的是在阴连接器主体12插入护罩16内时更靠近阴连接器主体12的前缘20的位置，而“向前地”指的是朝向阴连接器主体12的前缘20的方向。“向后”指的是距阴连接器主体12的前缘20更远的位置，而“向后地”指的是远离阴连接器主体12的前缘20的方向。在该特定示例中，组件10是电连接器组件，其中阴连接器主体和阳连接器主体12、14包含配合的电端子。
如图5所示，由诸如硅酮橡胶的顺应性材料形成的弹性密封件(以下称为密封件22)轴向地围绕阴连接器主体12的向前部分18。密封件22设置在向前部分18和护罩16中间。密封件22在密封件22的外表面和内表面上限定周向肋24，并且这些肋24与向前部分18和护罩16两者都是压缩接触的，以阻止诸如水或污物之类的环境污染物侵入到阴和阳连接器主体12、14中。如图所示，密封件22关于连接器主体的侧向轴线Y不对称。如本文所用，侧向轴线Y正交于、即垂直于纵向轴线X。
最佳地如图7所示，阴连接器主体12的向前部分18在阴连接器主体12的向前部分18上限定了从向前部分18向内延伸的向前保持壁架26。在所示的示例中，向前保持壁架26围绕向前部分18周向地延伸。密封件22限定了从密封件22的内表面32向外延伸的向前保持钩部30。向前保持钩部30与密封件22一体形成。向前保持钩部30构造成在阴连接器主体12与阳连接器主体14配合时接合向前保持壁架26并阻止密封件22向后移动。如本文所使用的，“向内”指的是朝向阴连接器主体12的纵向轴线X的方向，而“向外”指的是远离纵向轴线X的方向。向前保持壁架26向前倾斜，即相对于纵向轴线X形成锐角34。向前保持钩部30向后倾斜，即相对于纵向轴线X形成钝角36，该钝角36基本上与锐角34互补(该钝角36基本上与锐角34互为补角)。如本文所使用的，基本上补充(基本上互为补角)意味着锐角34的角度值加上钝角36的角度值等于180°±2°。向前保持钩部30的钝角36与向前保持壁架26的锐角34接合，从而在阴连接器主体12插入到护罩16内时更好地将密封件22保持在适当位置。
密封件保持器38附接到阴连接器主体12，以将密封件22保持在阴连接器主体12上的适当位置。密封件22限定了密封唇40，该密封唇40从向前保持钩部30向前延伸。当阴连接器主体12被接纳在阳连接器主体14的护罩16内时，密封唇40设置在向前部分18和密封保持器38中间，并且与向前部分18和密封保持器38压缩接触。密封唇40与密封件22一体形成。
最佳地也如图7所示，阴连接器主体12限定了被设置在密封件22向后的空间或腔体42，如图3A和3B所示，当阴连接器主体12与阳连接器主体14配合时，由于护罩16和密封件22之间的摩擦将密封件22向后拉，密封件22的后部可以膨胀到该腔体42中。该腔体42围绕阴连接器主体12周向地延伸。
阴连接器主体12限定了保持壁44，该保持壁44周向围绕向前部分18并且构造成接纳阳连接器主体14的护罩16的一部分。
发明人已经发现，组件的密封件22没有呈现收缩、成束和滚动的现象，这些现象会存在于在缺少从密封件22向后的保持钩部30和腔体42的现有技术的连接器组件的密封件中。在不遵循任何特定的操作理论的情况下，通过保持向前保持壁架26以及从密封件22向后的向前保持钩部30和腔体42协作来提供这些益处。如下表1所示，与现有技术的密封件相比，密封件22还提供了在密封件22和阳连接器主体14之间的较低的接合力，以及对密封间隙的较低的敏感性。接合力的减小还提供了用于组装操作人员手工配合连接器组件的改进的人机工程学。

表1–接合力的比较
图8和9示出了不对称的密封(密封件)设计的两个替代实施例的横截面。图8的密封件22A包括两个外肋24A和一个内肋24B，外肋24A接触阳连接器主体14的护罩16，内肋24B接触阴连接器主体12的向前部分18。图9的密封件22B包括三个外肋24A和两个内肋24B，外肋24A接触阳连接器主体14的护罩16，内肋24B接触阴连接器主体12的向前部分18。这两种密封件设计均是关于阴连接器主体12的侧向轴线Y不对称的。
图10和11示出了对称的密封件设计的两个替代实施例。这些对称的密封件设计包括附加的向后保持钩部46，向后保持钩部46可接合阴连接器主体12的向前部分18的向后保持壁架(未示出)。图10和11的密封件22C、22D包括两个外肋24A和两个内肋24B，外肋24A接触阳连接器主体14的护罩16，内肋24B接触阴连接器主体12的向前部分18。这两种密封件设计均是关于阴连接器主体12的侧向轴线Y对称的。
虽然本文中呈现的示例涉及电连接器组件，但是可以设想适合于与用于光纤电缆、气动管、液压管的其他类型连接器组件或包括上述两个或多个项的混合连接器组件一起使用的的其它实施例。
虽然已经根据本发明的优选实施例描述了本发明，但是本发明并不旨在受限于此，而是仅受以下的权利要求书中所阐述的范围限制。例如，上述实施例(和/或其方面)可以彼此结合使用。此外，可作各种修改以使得具体的情形或材料适应本发明的教导，而不偏离其主要范围。本文描述的尺寸、类型、各个部件的定向以及各个部件的数量和位置旨在限定特定实施例的参数，不意味着限制，而仅为原型实施例。
在阅读了以上描述后，在权利要求精神和范围内的各种其它实施例和变型对本领域的普通技术人员来说是显然的。因此，本发明的范围仅由所附权利要求书、以及这些权利要求所涵盖的等同物的全部范围所限定。
如此处使用的，“一个或多个”包括由一个元件执行的功能、如以分布的形式由超过一个元件执行的功能，由一个元件执行若干功能，由若干元件执行若干功能，或以上这些的组合。
因此理由，尽管在一些实施例中使用了术语第一、第二等被用来描述不同的元件，但是这些元件不应被这些术语限制。这些术语仅用来将一个元件区别于另一个元件。例如，第一触件可被称为第二触件，类似地，第二触件可被称为第一触件，这不会脱离描述的各个实施例的范围。第一触件和第二触件都是触件，但它们不是同一个触件。
在已描述的各个实施例中使用到的术语仅仅为了描述特定实施例，而不意指限制本发明。如已描述的各个实施例中使用到的，单数形式“一(a)”、“一个(an)”和“这个(the)”意在同样包括复数形式，除非上下文明确指出了其它情形。还应当理解术语“和/或”包括一个或多个相关联列出项目的任何和所有组合。还应理解的是，在本文中所使用的术语“包括”特指存在所陈述的特征、整体、步骤、操作、元件和/或部件，但并不排除存在或附加一个或多个其它特征、整体、步骤、操作、元件、部件和/或它们的组合。
在本文中所使用，术语“如果”可选地被解释为表示“当……时”或“在......时”或“响应于决定”或“响应于检测”，取决于上下文。类似地，短语“如果决定”或“如果检测到[已述的条件或事件]”可选地被解释为表示“在决定......时”或“响应于决定”或“在检测到[所述条件或事件]时”或“响应于检测到[所述的条件或事件]，”取决于上下文。
另外，虽然在此可以使用条例或定向的术语，但是这些元件不应受这些术语的限制。除非另有说明，否则所有条例或定向用于区分一个元件与另一个元件的目的，并且除非另有说明，否则不表示任何特定顺序，操作顺序，方向或定向。
