相关申请的交叉引用
本申请要求于2018年9月5日提交的美国临时申请第62/727,189 号的优先权，其全部主题内容以参见的方式纳入本文。
技术领域
本实用新型是一种将单对以太网线缆端接到连接器的装置，该连接器既建立了电气连续性，又为线缆提供了应变消除。本实用新型还结合了屏蔽特征部以改善连接器的电气性能。
背景技术
铜连接器正在变得越来越紧凑，以便以给定的面积实现更高密度的数据信道，以及用于需要将数据传输至诸如安全摄像机和气候控制设备之类的远程设备的应用场合中。通常要求使用简单的手动操作的工具在现场将这些紧凑的连接器安装到线缆上。通常，对于以太网数据连接，将使用RJ45插座作为互连来部署四对线缆解决方案。但是，对于例如但不限于安全摄像机和其它智能建筑设备的低带宽应用场合，超六类线(Cat 6a)的全带宽不是必需的。在这种情况下，可以部署单条双绞线布线解决方案，这将节省材料成本并减少结构化布线系统使用的空间量。随着最近使用铜介质的以太网带宽的进步，对于大多数智能设备而言，数据吞吐量将是足够的。通过允许安装人员构建定制的布线结构，并且仅使用最终用户应用场合所需的线缆量，现场可端接设计提供了优势。这种定制消除了对额外的布线管理技术的需要，这为现场技术人员部署结构化布线系统节省时间和资源。
工业和楼宇自动化应用场合中已经长期使用单对线缆系统来递送电力和非常低带宽的数据传输。该线缆的典型部署是被端接到螺钉端子。本文档中提出的单对连接器提供了一种标准化的方法来部署低成本的数据和电力递送系统，以实现与当今使用的并由IEEE 802.3cg标准所支持的相同的需求。单条双绞铜线解决方案影响了业界对以太网数据传输以及POE (以太网供电)能力的知识，以获得可靠而耐用的解决方案。
所需要的是一种端接设计，该端接设计能够适应于小形状因数，其制造简单且廉价，并且由安装者快速且容易地进行端接而无需复杂且昂贵的工具。该设计需要容纳各种线规的带遮蔽部和不带遮蔽部的线缆。
实用新型内容
通信连接器具有：带开口的外壳；屏蔽套，其至少部分地包围外壳；以及触头承载件组件，其构造成插入到外壳的开口中。触头承载件组件至少部分地包围至少两个触头，每个触头都带有绝缘位移触头(IDC)。触头承载件组件还具有集成的线帽，该线帽利用铰链特征部将线缆的线缆导体压入它们相应的IDC中。

具体实施方式
图1示出了具有由联接器8连结的两个单对以太网连接器的通信通道6。尽管示出了联接器，但单对以太网连接器能够与有源或无源设备一起使用，包括但不限于配线架、墙壁插座、以太网交换机、路由器、服务器和以太网供电设备。通讯通道6可以位于机柜、机架、区域包围件和其它此类基础结构中。
图2和图3示出了单对以太网连接器10，其具有外壳12、屏蔽套18和触头承载件组件22。
在图4中示出了外壳12。外壳12具有包围触头承载件的端接区域14。端接区域可以具有屏蔽突片消除部16，以允许屏蔽套接触线缆遮蔽部以用于接地。
图5中示出了屏蔽套18。该屏蔽套包围了外壳的端接区域，并且将由金属制成以减少来自相邻连接器的外来串扰的影响。屏蔽套具有接地突片20，接地突片20被设计成接触单对以太网线缆缆的遮蔽部。狭槽 21与触头承载件中的闩锁接合，以将承载件锁定到连接器壳体中。
在图6中示出了触头承载件组件22的分解图。承载件组件包括将两个铜触头26保持在适当位置的模制塑料主体24。通道27有助于将单对线缆的导体定位在承载件的端接区域中。触头26以使得建立最强的差分耦联的方式来布置，这又有助于抑制来自外部噪声源的不需要的耦联；强耦联的设计符合IEEE和TLA标准中定义的回波损耗特性。触头26的布置包括但不限于其中接触面并排或上下重叠的平行行进。本领域技术人员理解平行的重叠金属表面积导致最强的电场相互作用。承载件组件还具有应变消除特征部28，其设计成使用肋部30将单对线缆护套夹持到外部护套上。这防止了线缆与连接器分离并从触头端接区域拉出来。触头承载件具有集成的线帽32，该线帽使用铰链特征部34，以允许线帽向下枢转并向线缆导体施加压力，以将它们驱动到其各自的绝缘位移触头36中，以建立电连续性。随着将承载件组件推入外壳12中，斜面特征部38将力向下施加到线帽上。线帽32具有与主体24类似的应变消除肋部30，以便随着承载件组件插入到外壳端接区域14中，夹持线缆护套的顶部。
图7示出了触头承载件22的底侧，该底侧具有闩锁40，该闩锁 40与屏蔽套18的狭槽21接合，以将承载件锁定在连接器壳体中。
图8-10示出了用于将连接器端接到单对线缆42上的过程。端接的第一步在图8中示出。线缆42的外护套被向后剥开，并且屏蔽遮蔽部44 沿着线缆的外径被向后拉。将导体46修剪至规定的长度，并放置在承载件主体24的通道27中。然后，使线帽32绕铰链特征部34向下枢转到导体 46上，将它们驱动到绝缘位移触头36，中并建立电连续性。同时，线帽32的肋部30夹持到外部线缆护套上。
一旦线帽32已经向下枢转并且绝缘位移触头已刺穿线缆导体绝缘部，则将触头承载件组件22插入连接器外壳12的后部中，如图9所示。随着组件22被安装，斜面特征部38将力向下施加到线帽32上，以确保线缆导体被完全压入到绝缘位移触头中。线缆屏蔽层44沿触头承载件组件22 的侧部露出，允许它与屏蔽套18的突片20接触。突片20和线缆屏蔽屏44的连接沿线缆系统提供了连续的接地，从而消除了差分信号到共模信号的不必要转换。轴环86可帮助将触头承载件组件插入外壳中。本领域技术人员理解，地面参考的任何不连续或差异都会导致不希望的共模信号转换。
图10示出了触头承载件组件22经由承载件上的闩锁40以及屏蔽和连接器壳体上的狭槽21锁定到外壳12中。
图11示出了类似于图2-7中所示的组件。在该实施例中，触头承载件组件300在应变消除区域中具有槽口特征部302。这允许将单对线缆 42的线缆遮蔽部44布线到触头承载件外部。外壳屏蔽套308具有突片310，该突片310与线缆遮蔽部编织物304接触，以用于一旦触头承载件被插入屏蔽部中就接地。
图12示出了上述本实用新型的第一替代实施例，其中，电触头 101封装在外壳100中，并通过触头保持器102保持在适当的位置。触头保持器通过外壳闩锁104固定到外壳，该外壳闩锁104与触头保持器侧槽口 106接合。绝缘位移触头108水平定向并从连接器壳体的后部延伸。线帽和线缆应变消除部合并到单独的部件110中。线帽/应变消除部保持线缆导体垂直于与槽口112接触的触头绝缘位移部。随着用户将线帽/应变消除部推入连接器的后部中，线缆的导体被推入绝缘位移触头108中并建立电连接，同时，应变消除支脚114夹持到外部线缆护套上。线帽/应变消除部使用与顶部和底部槽口118接合的闩锁特征部116锁定到触头保持器中。屏蔽套 120包围外壳和触头保持器，并具有与线缆遮蔽部编织物接触的接地突片 122。
该实施例的端接过程从图13开始。用户将接收到带有预先组装好的外壳100、触头101、触头保持器102和屏蔽套120的连接器。将线缆 42的外护套向后剥开，并且将屏蔽层44沿着线缆的每一侧向后拉。将导线 46馈送通过线帽110的中心，并推入槽口112中，然后修剪成与线帽的外表面齐平。然后将应变消除支脚114向下枢转到线缆护套上，并且在将线帽推入连接器组件的后部中时，用作用户抓持握线帽的地方。图14示出了带有安装好的线缆的线帽110被插入到连接器组件124的后部。线缆42的屏蔽遮蔽部44与屏蔽套的接地突片122对齐，当安装好线帽时，在线缆和连接器之间形成电连结。如图15所示，在将线帽110完全插入连接器组件 124中之后，将线帽经由闩锁特征部116和触头保持器槽口118锁定到位。
图16示出了第二替代实施例并且描述了一种端接方法，其中，触头200位于塑料滑架202中，该塑料滑架被插入连接器壳体的后部204 中。连接器壳体具有带槽208的竖直壁206。在将塑料滑架插入连接器壳体后，线帽210安装在滑架上以建立线缆导体接触。线帽具有与连接器壳体狭槽208接合的闩锁212，以将线帽锁定在位。塑料滑架202和线帽210 具有应变消除特征部214，以支承和保持外部线缆护套。壳体屏蔽件216 包围连接器壳体204。壳体屏蔽件具有突片220，该突片220包裹在连接器壳体壁的内部，连接器壳体壁接触线帽屏蔽件218上的相应突片222。线帽屏蔽突片222包裹到应变消除区域中以接触线缆遮蔽部，从而产生完全接地的连接。
尽管已经示出和描述了本实用新型的具体实施例和应用场合，但是应理解的是，本实用新型不限于在此公开的确切构造和组合，并且在不偏离如所述的本实用新型的精神和范围的情况下，各种改型、变化和变型可能从上文是显而易见的。
