Description

具有空气循环和定位特征的电连接器
本申请是申请日为2007年5月26日、申请号为200780022156.8、发明名称为“具有空气循环和定位特征的电连接器”的发明专利申请的分案申请。
技术领域
本发明涉及用于传递电力的电连接器。
背景技术
电子设备的操作电流的增大通常允许设备在比可能的更低的电压下操作。电子设备的制造因此通常要求或需要电触头具有相对高的电流额定值。因此，希望将电触头在操作过程中经受的温升减小到最低。
将触头装配到连接器外壳中也可以带来问题。触头可以被插入到不适当的空腔中或仅仅部分地插入到空腔中。
发明内容
电连接器的实施例包括便于空气通过和围绕电连接器循环的特征。空气可以冷却电连接器的电触头，从而允许电触头在比可能的更高的电流下操作。还包括有助于防止触头误插入或部分插入到外壳中的特征。
连接器系统的实施例包括第一电连接器，第一电连接器包括界定了空腔的电绝缘外壳。外壳具有形成于其中的孔，该孔将空腔与围绕第一电连接器的环境流体连通。第一电连接器也包括具有设置在空腔内的配合部的电触头。
连接器系统也包括与第一电连接器配合的第二电连接器。第二电连接器包括界定了空腔的电绝缘外壳。第二电连接器的外壳具有形成于其中的孔，该孔将第二电连接器的空腔与围绕第二电连接器的环境流体连通。第二电连接器也包括电触头，该电触头具有设置在第二电连接器的外壳的空腔内的配合部。
当第一和第二电连接器配合时，第一和第二电连接器的外壳中形成的孔重叠。
用于安装在基底上的电连接器的实施例包括电触头和容纳该电触头的电绝缘外壳。孔形成于该外壳中。该孔与电触头的配合部对齐，藉此由电触头加热的空气可以经由该孔离开电触头。凹槽形成于该外壳中。当电连接器安装在基底上时，该凹槽面向基底并且该凹槽和基底界定了从外壳的侧部延伸的通道。一部分电触头延伸穿过该凹槽，藉此来自围绕电连接器的环境的空气可以在外壳和基底之间和电触头上方经过。
电连接器的实施例包括电绝缘外壳和安装在该外壳内并且具有配合部的电触头。该外壳具有孔，该孔形成于外壳上并且与配合部对齐，藉此由电触头加热的空气可以经由该孔离开电触头。
电连接器的实施例包括外壳和两种不同类型的电触头。电触头包括降低或消除电触头不正确地安装在外壳中的可能性的定位特征。
电连接器的实施例包括：包括翼片的第一电触头；包括翼片的第二电触头；和外壳，该外壳具有形成于其中的第一和第二空腔，第一和第二空腔容纳各自的第一和第二电触头。当第一电触头部分地插入第二空腔中时，第一电触头的翼片干涉地接触外壳，因此防止第一电触头安装内第二空腔中。当第二电触头部分地插入第一空腔中时，第二电触头的翼片干涉地接触外壳，因此防止第二电触头安装内第一空腔中。

具体实施方式
图1至图12显示了共面连接器系统10的实施例。附图可以参考其中显示的共同的坐标系统11。连接器系统10包括插头连接器12和与该插头连接器12配合的插座连接器14。插头连接器12可以安装在基底例如印刷电路板(PCB)16上，并且插座连接器14可以安装在基底例如PCB 18上。插头连接器12和插座连接器14在配合时电连接PCB 16和PCB 18。
插头连接器12包括电绝缘的外壳22和多个安装在外壳22中的电触头24。每个电触头24均包括一个第一半26和一个第二半28，如图11所示。第一半26包括板状主体构件30a和与主体构件30a的下端邻接的基本上S形部分31。第一半26还包括多个均从S形部分31的下端延伸的尾销32。
第一半26还包括三个倾斜的触头梁34a和两个均从主体构件30a的前沿延伸的基本上直的触头梁36a。倾斜触头梁34a和直触头梁36a以交错的方式布置在主体构件30a上，即，每个直触头梁36a邻近两个倾斜触头梁34a放置。
方向术语例如“上”、“下”、“前”、“后”、“顶”、“底”、“上方”、“下方”等等是参照图1中所示部件的朝向使用的。这些术语仅仅用于示例性目的并且并非用于限制所附权利要求书的范围。
每个电触头24的第二半28均包括板状主体构件30b和邻接主体构件30b的下端的另一个S形部分31。第二半28也包括多个均从S形部分31的下端延伸的尾销32。
第二半28还包括三个倾斜的触头梁34b和两个均从主体构件30b的前沿延伸的基本上直的触头梁36b。倾斜触头梁34b和直触头梁36b以交错的方式布置在主体构件30b上，如图11所示。
主体构件30a、30b彼此堆叠，如图11中所示，这样每个倾斜的触头梁34a就面向并且远离相关联的倾斜触头梁34b；并且每个直触头梁36a面向并且压靠相关联的触头梁36b。当主体构件30a、30b堆叠时，S形部分31在第一半26的尾销32和第二半28的尾销32之间提供偏移。
每个主体构件30a、30b均包括位于其后上角的翼片42。翼片42向外倾斜，所图11中所示。在电触头24从外壳22的后端部插入外壳22中时，每个翼片42均可以接触外壳22上的相关联的凸缘(未显示)。翼片42和凸缘之间的接触导致翼片42向内偏转。当电触头24接近其在外壳22内的完全插入位置时，翼片42掠过该凸缘。一旦翼片42掠过凸缘，翼片42的回弹力导致翼片42向外朝弹回其初始位置。翼片42和凸缘之间的干涉可以阻止电触头24从后面离开外壳22。
电触头24的特定细节仅仅是出于示例性目的提出的。本发明的原理可以应用到包括其它类型的电触头的连接器上，这些连接器包括上文中交叉引用的相关申请中所描述的电触头。
外壳22包括主体43和邻接的配合部44，如图1至4所示。主体43具有多个形成于其中的空腔45，如图1和3所示。每个空腔45均容纳相关联的电触头24的主体构件30a、30b。空腔45均部分地由外壳22的肋46界定。肋46以相对的对布置。当电触头24滑动到空腔45中时，肋46与相关联的电触头24的主体构件30a或30b接触。肋46和主体构件30a、30b之间的干涉会将主体构件30a、30b推到一起，并且有助于将电触头24保持在空腔45内。
肋46在其间界定了槽48，所述图1和3中所示。如下面讨论的那样，槽48便于在插头连接器12的操作过程中从电触头24的热传递。
外壳22的主体43包括前壁52。前壁52部分地显示在图4中。空腔45延伸穿过前壁52，这样电触头24的倾斜触头梁34a、34b和直触头梁36a、36b就可以在电触头24从外壳22的后端部插入其中时经过前壁52。
外壳22的配合部44包括顶部56、底部58和侧部60、62，如图1-4和9所示。顶部56、底部58、侧部60、62和前壁52界定了配合区域或空腔64，如图4中所示。空腔64邻接主体43的空腔45。当插头连接器12安装在PCB 16上时，配合部44悬垂PCB 16的前沿，如图1至4和9所示。
电触头24的倾斜触头梁34a、34b和直触头梁36a、36b延伸到空腔64内，如图4中所示。如下文论述的那样，当插头连接器和插座连接器12、14配合时，空腔64容纳插座连接器14的一部分。
插头连接器12可以包括信号触头70的阵列68。阵列68可以设置在电触头24的一侧，如图4所示。阵列70的一部分可以置于外壳22中形成的空腔71中，如图3所示。在插头连接器12的可选实施例中，阵列70可以位于电触头24之间插头连接器12的中心处或其附近。其它可选实施例可以放弃任意信号触头70的使用。
外壳22的主体43具有顶部75、底部76和侧部77、78，如图1-4所示。多个长槽或孔80优选地形成于顶部75中，如图1、3、4、5和7所示。每个孔80均设置在相关联的电触头24的主体部30a、30b上方。孔80沿外壳22的横向或“z”方向延伸。
孔80均邻接相关联的空腔45，并且因此使空腔45放置成与围绕插头连接器12的环境流体连通。优选地，每个孔80的宽度或“x”尺寸与相关联的电触头24的主体部30a、30b的组合宽度或“x”尺寸一样大或是更大。
附加的孔82优选地形成于主体43的顶部75中，邻近其后端部，如图1、3、4、5和7所示。每个孔82均邻接相关联的空腔45并且设置在相关联的电触头24的翼片42上方，如图5和7所示。孔82将空腔45的后端部放置成与围绕插头连接器12的环境流体连通。优选地，每个孔82的“x”尺寸大约等于或大于相关联的电触头24的翼片42的末端到末端的宽度。
孔84优选地形成于配合部44的顶部56中，如图1和3-8所示。孔84邻接空腔64。每个孔84均设置在相关联的电触头24的倾斜触头梁34a、34b和直触头梁36a、36b上方，即每个孔84均沿“y”方向与相关联的电触头24的倾斜触头梁34a、34b和直触头梁36a、36b对齐，如图6和8所示。
孔84将空腔64放置成与围绕插头连接器12的环境流体连通。优选地，每个孔84的宽度或“x”尺寸均与相关联的电触头24的直触头梁36a、36b的组合宽度一样大或是更大，如图6和8中所示。
孔86优选地形成于配合部44的底部58中，如图9和10中所示。孔86邻接空腔64，并且基本上类似于孔84。每个孔86均设置在相关联的电触头24的倾斜触头梁34a、34b和直触头梁36a、36b下方，即每个孔86均沿“y”方向与相关联的电触头24的倾斜触头梁34a、34b和直触头梁36a、36b对齐，如图10中所示。孔86将空腔64放置成与围绕插头连接器12的环境流体连通。
凹槽92优选地形成于外壳22的主体43的底部76中，如图1和2中所示。凹槽92基本上沿外壳22的纵向或“x”方向在侧部78和空腔71之间延伸。另一个凹槽94优选地形成于底部76中侧部77和空腔71之间，如图3和4中所示。凹槽94基本上沿“x”方向与凹槽92对齐。
凹槽92、94在插头连接器12安装在其上时均面向PCB 16。凹槽92、94、空腔71和PCB 16界定了在外壳22的整个长度或“x”尺寸上延伸的通道98。
插座连接器14包括电绝缘的外壳122和多个安装在外壳122中的电触头124。电触头124配置成与插头连接器12的电触头24配合。
每个电触头124均包括一个第一半126和一个第二半128，如图12中所示。除第一半和第二半126、128均包括两个倾斜触头梁34a和三个基本上直的触头梁36a之外，电触头124基本上与电触头24相同。电触头124中与电触头24中基本上相同的部分在图中以相同的参考数字表示。
第一半12的倾斜触头梁34a和直触头梁36a以交错的方式布置在第一半126的主体构件30a上，即，每个倾斜触头梁36a均邻近两个直触头梁34a放置，如图12中所示。倾斜触头梁34b和直触头梁36b同样以交错的方式布置在第二半128的主体构件30b上。
插座连接器14的外壳122包括主体143和邻接的配合部144，如图3和4中所示。当插头连接器和插座连接器12、14配合时，配合部144，如下文所述，容纳在插头连接器12的空腔64内。
外壳122具有多个形成在其中的空腔145，如图4中所示。空腔145均在外壳122的前端部和后端部之间延伸穿过主体143和配合部144。每个空腔145均容纳相关联的电触头124的主体构件30a、30b、倾斜触头梁34a、34b和直触头梁36a、36b。当电触头124插入外壳122中时，每个电触头124的倾斜触头梁34a、34b和直触头梁36a、36b均位于配合部144内。
每个空腔45均部分地由外壳122的肋146界定。肋146以相对的对布置，如图4中所示。当电触头124滑动到空腔145中时，肋146与相关联的电触头124的主体构件30a或30b接触。肋146和主体构件30a、30b之间的干涉会将主体构件30a、30b推到一起，并且有助于将电触头124保持在空腔145内。
肋146在其间界定了槽148。如下面讨论的那样，槽148便于在插座连接器14的操作过程中从电触头124的热传递。
插座连接器14可以包括信号触头170的阵列168，如图3所示。阵列168可以设置在电触头124的一侧，如图3所示。一部分阵列168可以置于外壳122中形成的空腔171中，如图4中所示。在插座连接器14的可选实施例中，阵列168可以位于电触头124之间插座连接器14的中心处或是附近。其它可选实施例可以放弃任意信号触头170的使用。
外壳122的主体143具有顶部175、底部176和侧部177、178，如图1-4中所示。多个长槽或孔180优选地形成于顶部175中，如图1、3、4、5和7中所示。每个孔180均设置在相关联的电触头124的主体部30a、30b的上方。孔180沿外壳124的横向或“z”方向延伸。孔180均邻接相关联的空腔145，并且因此使空腔145放置成与围绕插座连接器14的环境流体连通。优选地，每个孔180的宽度或“x”尺寸与相关联的电触头124的主体部30a、30b的组合宽度或“x”尺寸一样大或是更大。
附加的孔182优选地形成于主体143的顶部175中邻近其后端部。每个孔182均邻接相关联的空腔145并且设置在相关联的电触头124的翼片42上方，如图5和7中所示。孔182将空腔145的后端部放置成与围绕插座连接器14的环境流体连通。每个孔182的宽度或“x”尺寸大约等于或大于相关联的电触头124的翼片42的末端到末端的宽度，如图5和7中所示。
外壳122的配合部144在插座连接器14安装在PCB18上时悬接PCB18的前沿，如图3和4中所示。配合部144具有顶部156和底部(未显示)。孔184优选地形成于顶部156中，如图3-8中所示。孔184均邻接相关联的空腔145的前端。每个孔184均设置在相关联的电触头124的倾斜触头梁34a、34b和直触头梁36a、36b上方，即每个孔184均沿“y”方向与相关联的电触头124的倾斜触头梁34a、34b和直触头梁36a、36b对齐，如图5和6中所示。
孔184将相关联的空腔145放置成与围绕插座连接器14的环境流体连通。优选地，每个孔184的宽度或“x”尺寸均与相关联的电触头124的直触头梁36a、36b的组合宽度一样大或是更大，如图6中所示。
孔186优选地形成于配合部144的底部中，如图10中所示。孔186均邻接相关联的空腔145的前端，并且基本上类似于孔184。每个孔1186均设置在相关联的电触头124的倾斜触头梁34a、34b和直触头梁36a、36b下方，即每个孔186均沿“y”方向与相关联的电触头124的倾斜触头梁34a、34b和直触头梁36a、36b对齐，如图10中所示。每个孔186均将相关联的空腔145放置成与围绕插座连接器14的环境流体连通。
凹槽192优选地形成于外壳122的主体143的底部176中，如图3和4中所示。凹槽192基本上沿外壳122的纵向或“x”方向在侧部178和空腔171之间延伸。另一个凹槽194优选地形成于底部176中侧部177和空腔171之间，如图1和2中所示。凹槽194基本上沿“x”方向与凹槽192对齐。
当插座连接器14安装在PCB 18之上时，凹槽192、194均面向PCB 18。凹槽192、194、空腔171和PCB 18界定了在外壳122的整个长度或“x”尺寸上延伸的通道198。
插塞和插座连接器12、14通过将插座连接器14的配合部144与插塞连接器12的空腔64的对准来进行配合。然后插塞和插座连接器12、14中的一个或两者朝彼此移动，直至配合部144开始进入空腔64。插塞和插座连接器12、14朝彼此的进一步运动会使插塞连接器12的电触头24的每个倾斜触头梁34a、34b和直触头梁36a、36b进入插座连接器14的外壳122的相关联的空腔145。
电触头24的每个相关联对的直触头梁36a、36b随后进入电触头124的相关联对的倾斜触头梁34a、34b之间的空间，如图5和6中所示。直触头梁36a、36b和倾斜触头梁34a、34b之间的接触导致倾斜触头梁36a、36b沿向外方向即沿远离直触头梁34a、34b的方向弹性地偏转。电触头24的倾斜触头梁34a、34b的弹性偏转导致电触头124的倾斜触头梁34a、34b和电触头24的直触头梁36a、36b之间的接触力。
电触头124的每个相关联对的直触头梁36a、36b同样进入电触头24的相关联对的倾斜触头梁34a、34b之间的空间。电触头24的倾斜触头梁34a、34b引起的偏转导致电触头124的倾斜触头梁34a、34b和电触头124的直触头梁36a、36b之间的接触力。
当插塞和插座连接器12、14完全配合时，PCB16和PCB 18的前沿将间隔开一个间隙。该间隙在图1、2和9中以参考符号“d”表示。
外壳22的孔84和外壳122的孔184放置成当插头连接器和插座连接器12、14完全配合时，每个孔84均与相对应的孔184重叠或基本上对齐，如图8中所示。
外壳22的孔86和外壳122的孔186同样放置成当插头连接器和插座连接器12、14完全配合时，每个孔86均与相对应的孔186重叠或基本上对齐，如图10中所示。
孔84、86、184、186便于通过外壳22、122和在电触头24、124上方的空气循环。该空气循环可以助于在操作期间冷却电触头24、124。
例如，图1和2包括箭头200，该箭头200指示其中空气可以通过插头连接器和插座连接器12、14循环的一种可能的方式。在该特定情形中，一个或多个冷却风扇(未显示)被用于指引空气向下并且在插头连接器和插座连接器12、14上方。重叠的孔84、184允许相对冷的向下流动的空气进入各个外壳22、122的配合部44、144。进入配合部44、144的空气可以置换配合部44、144内的空气，而该空气已由相对热的电触头24、124的倾斜触头梁34a、36a和直触头梁36a、36b加热。
下孔86、186可以允许已经由更冷的进入空气在配合部44、144内置换的热空气离开配合部44、144。PCB 16、18之间的间隙“d”允许离开配合部44、144的空气自由地流动到围绕插头连接器和插座连接器12、14的环境中。
当空气被迫向下并且在倾斜触头梁34a、34b和直触头梁36a、36b上方时，热能从倾斜触头梁34a、34b和直触头梁36a、36b转移到相对冷的空气。该对流的热传递会冷却倾斜触头梁34a、34b和直触头梁36a、36b而同时加热空气。加热的空气又会被迫向下并且通过重叠的下孔86、186，导致配合部44、144内的空气循环型。该循环会耗散电触头24、124热能，因此冷却电触头24、124。
孔80、180也便于在操作过程中冷却各个电触头24、124。特别是，孔80、180允许相对冷的空气被迫向下到插头连接器和插座连接器12、14的上方以冲击电触头24、124的每个主体部30a、30b的顶部。相对冷的空气在主体部30a、30b上的冲击有助于耗散电触头24、124的热能。
孔82、182同样便于各个电触头24、124的冷却。特别是，孔82、182允许相对冷的空气被迫向下到插头连接器和插座连接器12、14的上方以冲击电触头24、124的每个翼片42的顶部。相对冷的空气在翼片42上的冲击有助于耗散电触头24、124的热能。
各个外壳22、122的槽48、148设计成当插头连接器和插座连接器12、24配合时每个槽48基本上与相关联的槽148对齐。该配置可以便于电触头24、124的冷却。例如，相对冷的空气可以沿“z”方向由一个或多个附加的冷却风扇被迫到插头连接器和插座连接器12、14上方，如图1和2中所示。冷却空气可以进入槽48的后端部。当每个槽48与外壳122中的相应的槽148对齐时，冷却空气可以移动经过插头连接器和插座连接器12、14的整个组合宽度或“z”尺寸，并且可以经由槽148的远端离开外壳22。
被迫通过槽48、148的冷却空气可以经过电触头24、124的相对热的主体部30a、30b。空气通过对流热传递耗散主体部30a、30b的热能，因此冷却电触头24、124。
形成于外壳22内的凹槽92、94和空腔71与PCB 16界定了通道98，如上所述。通道98可以便于电触头24的冷却。特别是，相对冷的空气可以由一个或多个附加的冷却风扇沿“x”方向迫使进入和通过通道98，如图1中所示。电触头24的S形部分31和邻接尾销32部分地设置在通道98内，如图2中所示。流过通道98的空气可以在S形部分31的上方和下方并且在尾销31之间流动。相对冷的空气通过对流热传递耗散电触头24的热能，从而冷却电触头24。
形成于外壳122内的凹槽192、194和空腔171与PCB 18界定了通道198，如上所述。通道198便于插座连接器14的电触头124以上文相对于通道98论述的方式的冷却。
插头触头和接受器触头12、14的上述空气循环特征便于冷却空气在插头连接器和接受器触头12、14内的三维循环。由这些特征促进的电触头24、124的冷却允许电触头24、124在比可能的电流更高的电流下操作。特别是，电触头24、124的最大电流额定值可以由电触头24、124内的最大可接受的温度升高限制。由上述空气循环特征中的一些或所有促进的热耗散可以允许电触头24、124在较高电流下操作，且与其中电触头24、124在并未冷却的应用中经受相同的温升。因此，电触头24、124的最大额定电流可以增大而基本上不会增大其中的温升。
上述气流图案和图中所示的气流图案仅仅是出于示意性目的提供的。通过和围绕插头连接器和插座连接器12、14的气流图案可以是比在此描述和所示的图案更复杂。此外，当插头连接器和插座连接器12、14的朝向不同于图中所示时，气流图案可以改变。
通过从不同于在此所述的方向将冷却空气对准插头连接器和插座连接器12、14，可以生成不同的气流图案。而且，插头连接器和插座连接器12、14可以操作而没有强制通风冷却；该类应用中的热耗散主要通过自然对流实现。
前述说明只是为了解释的目的提供的并且不应解释为限制本发明。虽然已经参照优选实施例或优选方法描述了本发明，但是应当理解，在此使用的单词是描述和说明的单词而不是限制的单词。另外，虽然在此参照特定结构、方法和实施例描述了本发明，但是本发明并非用来限于在此公开的特例，因为本发明扩展到所附权利要求书的范围内的所有结构、方法和应用。本领域的普通技术人员在本说明书的教导下，可以对在此所述的本发明实现众多变体，并且可以不脱离由所附权利要求书界定的本发明的范围和精神而做出改变。
例如，图13和14显示了连接器系统210形式的可选实施例。连接器系统210设计成用作底板连接器系统。连接器系统210可以包括如上相对于连接器系统10描述的插头连接器12。连接器系统210还可包括与插头连接器12配合的垂直插座连接器212。插头连接器12可以安装在子卡213上。插座连接器212可以安装在基本上垂直于子卡213定向的母板214上。
插座连接器212可以具有如上相对于插座连接器14描述的基本上类似或相同的特征以便于通过和围绕插座连接器212的空气循环。例如，插座连接器212可以具有外壳216，外壳216具有配合部(未显示)，当插头连接器和插座连接器12、212配合时，该配合部由插头连接器12的配合部43容纳。外壳216的配合部具有形成于其顶部和底部中的孔。这些孔可以与插头连接器12的配合部44中形成的孔84、184对齐。
插座连接器212的外壳216可以具有一个或多个形成于其中的凹槽218。凹槽218和母板214可以界定通道220，通道220便于外壳216和母板214之间的空气循环，空气循环的方式为上文相对于由插座连接器14和PCB 18界定的通道198所述的方式。
图15-21显示了插头连接器300形式的插头连接器12的可选实施例。除了另外指出之外，插头连接器300与插头连接器12基本上类似或相同。
插头连接器300包括外壳301、短电触头302和长电触头304。短电触头302容纳在外壳301中形成的空腔306内。长电触头304容纳在外壳301中形成的空腔308内。
外壳301、短电触头302和长电触头304包括防止短电触头302插入空腔308中或防止长电触头304插入空腔306的定位特征。特别是，每个空腔306、308均具有形成于其中的窗口312。与每个空腔306相关的窗口312邻近空腔306的下端设置，如图15、17和18所示。与每个空腔308相关的窗口312邻近空腔306的上端设置。
短和长电触头302、304均包括主体构件314a、314b，如图16A和16B所示。短和长电触头302、304还包括邻近每个主体构件314a、314b的后沿设置的翼片316。翼片316沿基本上垂直于主体构件314a、314b的主表面的方向延伸。每个短电触头302的翼片316均邻近短电触头302的下端设置。每个长电触头304的翼片316均邻近长电触头304的上端设置。
翼片316的尺寸设计成装配在外壳301的窗口312内。与空腔306相关的窗口312和每个短电触头302的翼片316放置成当短电触头302插入空腔306中时，短电触头302的翼片316均对齐，并且由空腔306的相关联的窗口312之一容纳，如图17所示。
当尝试将短电触头302之一插入空腔308之一中时，短电触头302的翼片316不会与空腔308相关的窗口312对齐。而且，翼片316和外壳301之间的干涉可以防止短电触头302进入空腔308中，如图18和19中所示。
与空腔308相关的窗口312和每个长电触头304的翼片316同样放置成当长电触头304插入空腔308中时，长电触头304的翼片316均对齐，并且由空腔308的窗口312容纳，如图17所示。
当尝试将长电触头304之一插入空腔306之一中时，长电触头304的翼片316不会与空腔306相关的窗口312对齐。而且，翼片316和外壳301之间的干涉可以防止长电触头304进入空腔306中，如图18和19中所示。
短和长电触头302、304的主体构件314a、314b均包括翼片328，如图16A、16B、20和21所示。当短和长电触头302、304完全插入外壳301中时，翼片328与外壳301干涉地接合。翼片328和外壳301之间的干涉有助于将短和长电触头302、304保持在外壳301中。外壳301包括斜坡303，当主体构件314a、314b插入外壳301中时，斜坡303有助于将翼片328导入它们的最终位置。
当长电触头304无意中安装在空腔306中时长电触头304的翼片316和外壳301之间的上述干涉可以防止长电触头304充分地进入空腔306中用于使相关联的翼片328干涉地接合外壳301的相关联的斜坡303。当短电触头302无意中安装在空腔308中时短电触头302的翼片316和外壳301之间的上述干涉同样可以防止短电触头302充分地进入空腔308中用于使相关联的翼片328干涉地接合相关联的斜坡303。
每个短和长电触头302、304的第二半314b均可以包括两个圆柱形凸起350，如图16A和16B中所示。每个短和长电触头302、304的第一半314a可以包括两个彼此容纳凸起350之一的圆孔352。短电触头302上的两组凸起350和孔352的相对位置可以不同于长电触头304上两组凸起350和孔352的相对位置。凸起350和孔352因此可以充当偏转特征，防止短电触头302的第一半无意中与长电触头304的第二半配合，反之亦然。
凸起350和孔352在可选实施例中可以具有不同于圆柱形和圆形的各自的形状。此外，凸起350和孔352在可选实施例中可以分别位于短和长电触头302、304的第一半和第二半323a、323b上。
图22A至24显示了短电触头320和长电触头322形式的短和长电触头302、304的可选实施例。除了短和长电触头320、322包括从短和长电触头320、322的相关联的主体构件323a、323b向外和向下倾斜的翼片324之外，短和长电触头320、322从结构和功能观点基本上类似于各自的短和长电触头302、304。
