相关申请
本申请主张于2012年11月27日提交的美国临时申请61/730,385和2013年5月21日提交的美国临时申请61/825,666的优先权，这两个美国临时申请通过援引其整体并入本文。
技术领域
本申请涉及端子的领域，尤其涉及可安装于一电路板上的端子的领域。
背景技术
端子被设置成用于连接到电路板。这种结构(desgin)可设置成焊接或压接配合到所述电路板上设置的通孔中。对于要求具有更高牢靠性的应用而言，这种结构倾向于更多地关注可焊接于所述电路板的端子结构。两个基本的设计是可行的，其中一种设计是设置有一壳体，而另一种设计是不设置一壳体。壳体提供诸多益处，但是趋于使成本更高。因此，某些应用可能通过仅有端子的设计会更合适。然而，现有的结构不趋于提供一低高度的外形。由此，某些人群会赏识对端子结构和线对板连接器上的进一步的改进。
发明内容
公开了一种端子组件，其中所述端子能够固定于包括包覆在一导体周围的一绝缘层的导线，且所述端子包括一第一压接部和一第二压接部。所述第一压接部设置成接合所述绝缘层和所述导体。所述第二压接部设置为接合于移除了所述绝缘层的所述导体。所述第一压接部和第二压接部各自包括一对朝向彼此弯折的翼部，从而当所述端子固定于所述导线时，所述一对翼部牢固地抓握住所述导线的对应区域。两个腿部位于所述第一压接部和所述第二压接部之间，其中所述两个腿部位于所述端子的相对两侧或所述两个腿部位于所述端子的相同侧。所述两个腿部设置成焊接于一电路板且包括设置成具有针眼式结构的尾部或任何其它可用于焊接于所述电路板的常规尾部结构。由此，一导线能够以一低高度外形的方式电连接于所述电路板。

具体实施方式
以下详细说明描述了示例性实施例并且不意欲限制到这些明确公开的组合。因此，除非另有说明，本文所公开的多个特征可以组合在一起，以形成出于简明目的而未另外说明的其它组合。
从附图中可看出，所述端子组件包括多种益处。如图1和图2所示，一端子10设置成安装到电路板5，电路板5包括多个通孔6且支撑一导线50，导线50包括一导体55和一绝缘层58。如图3和图4进一步所示，所述端子10包括用于将所述导线50和所述端子10固定在一起的位于一基部15上的一第一压接部20以及一第二压接部30。第一压接部20包括多个翼部22a、22b，并且第二压接部30包括分别朝向彼此弯折以牢固地抓住导线50的翼部32a、32b。
如图5最佳所示，一对腿部40位于第一压接部20和第二压接部30之间。每一个腿部40包括一尾部44。尾部44示出为具有一针眼式结构，但是如果需要也可以是一简单的通孔结构。所述针眼结构的益处在于端子10可在一回流焊工作之前更牢固地设置在电路板5上。然而与常规的针眼结构相比，所示出的实施例可设置为与用于提供一压接配合结构的一针眼结构相比，以更小的过盈配合被固持在电镀的通孔中。例如，通常的压接配合结构被设计成端子尾部宽度比对接通孔的直径大至少15％(且优选大至少20％)。相比之下，所示出的结构将具有设计成用于提供一过盈配合的一尾部宽度，但是所述过盈配合被降低，即所述尾部宽度大于所述电镀通孔的直径的量少于15％、代表性地少于12％甚至有可能少于11％。已确认的是，除了固持力之外，由于改进的焊接连接和增加的表面积，所述尾部44上的所述开孔有助于在所述尾部44和所述通孔6之间提供一更好的电连接，从而所示出的结构有助于降低阻抗并提高连接器系统的性能。
所述结构的一益处在于压接部30接合所述绝缘层58，这提供了另外的结构上的益处，因为绝缘层58和导体55的组合比导体55自身强度更大。所示出的结构的另一个益处在于，所述两个腿部40接合第一压接部20和第二压接部30之间的电路板5，从而有助于保证作用到所述导线50上的力不会明显地作用在第一压接部20(从而有助于保护所述导线50和所述端子10之间的电连接)。基部15在两相对侧上的所述两个尾部44的平衡结构进一步有助于将力分配到所述电路板5，这实际上应有助于保护端子10和支撑电路板5之间的电连接。在一实施例中，端子10可设置成第二压接部30直接搁在电路板5上，同时第一压接部20是位于稍高于电路板5。
从图中可以看出，所述多个腿部40具有沿与一B方向基本垂直的一A方向延伸的多个尾部44，所述B方向由图2和图6A-6C示出的电路板5的表面所定义。换句话说，尾部44可与电路板5垂直或甚至正交。如所示出的，尾部44延伸穿过支撑电路板5。当端子10焊接于电路板5时，这允许一焊接圆角形成在所述电路板5的相对侧上，以增加固持力。
应当注意的是，基部15可设置成第二压接部30直接放在所述电路板5上而第一压接部20相对所述电路板5向上升起。利用电路板5为端子10提供进一步的支撑，可以预期将有助于进一步确保端子10将不会意外地从电路板5上移除。由此，基部15可提供所述第一压接部20和所述第二压接部30开始延伸的一水平位置，然而第二压接部30的大尺寸，连同所示出的所述多个腿部40的朝向将导致其首先接触一支撑电路板5，并且将有助于为所述端子10提供另外的支撑。由此，示出的实施例允许一导线50以一低高度外形的方式电连接于一支撑电路板5。
图9和图10示出另一种结构，两个腿部140形成在第一压接部120和第二压接部130之间，并且所述两个腿部140从基部115的相同侧沿一C方向延伸。基部115可以形成为具有一第一表面的一平板，并且所述两个压接部可形成并且被支撑为使它们处于远离所述第一表面一距离的位置。在这种结构中，端子110旋转90度，其中腿部140位于与端子110的基部115相同的平面上。类似地，所述多个腿部140具有以一垂直或正交的方式收容在电路板105上形成的多个电镀通孔106中的多个尾部144。此外，第一压接部120包括多个翼部122a、122b，所述第二压接部130包括分别朝向彼此弯折以便牢固地抓住导线150的翼部132a、132b。
实质上，如图7和图8所示，端子110被侧向定位，使第一压接部120接合导线150的导体155，而第二压接部130接合包覆导线150的导体155的绝缘层158，同时第一压接部120位于稍高于电路板105处，而第二压接部130直接放在电路板105上并且还由电路板105支撑。在这个结构中，多个腿部140上具有多个尾部144，这些尾部144上形成有设置成压入到电路板105的电镀通孔106中并被焊接的一针眼结构(如上所述)。所述尾部也可以放置到一通孔结构中，其中所述尾部焊接于设置在所述电路板的相反侧的接触垫上。如所认识到的是，两个腿部140从基部115的相同侧延伸出来。
如前所述，端子110提供一低高度外形的结构，以最小化端子110从所述电路板105延伸的高度。如所示出的，所述端子110保持一低高度外形结构，而且当在工作时，即安装到所述电路板105上时还保持并列布置的端子110之间的一紧密的间隔。如图10最佳所示，两个腿部140从端子110的基部115沿一C方向延伸，这允许导线150以一第一方向上延伸离开端子110。在另一个结构中，多个腿部140也可以从端子110的基部115的相反侧沿一D方向延伸，这实质上形成所述端子110的一翻转或镜像形式。所述镜像形式允许导线150沿所述第一方向延伸，与此同时使两个压接部的位置相对所述基部115成为镜像。如图11所示的这种结构，相邻的端子110、110’可以以一背对背靠近的布置设置在一电路板105上，以进一步最小化端子间隔。由此，一实施例可包括一第一端子组件和一第二端子组件，所述两个端子组件设置成以一背对背方向对接于一电路板105，并且所述两个端子110、110’设置成使所述第一腿部和第二腿部在所述两个结构中从所述基部115的相同侧延伸。
本文提供的内容借助其优选且示例性的实施例说明各个特征。本领域普通技术人员通过阅读本说明书，将可做出在随附权利要求书的范围和精神内的许多其它的实施例、修改和变形。
