Description
技术领域
本发明总体上涉及用于电子设备的连接器系统,特别涉及利用管脚和插座类型触头(也就是端子)的连接器系统,所述触头为例如典型地可在MATE-NLOK系统或者类似系统中找到的触头,其中管脚和插座式触头可被修改从而能够利用拔取工具容易地从连接器壳体中拔取。
背景技术
“Molex连接器”是用于两件式“管脚和插座”类型的常用于磁盘驱动连接器与其它装置的互连的常用术语。先由Molex Products Company公司开发出来的两件式设计成为电子行业的早期标准。首先用于家用设备,其它行业迅速开始将这些连接器引入到产品中,从机动车辆到自动售货机到微型计算机。这些连接器包括圆柱的弹簧金属管脚,其配合到圆柱的弹簧金属插座中。管脚和插座通常配置为矩形阵列,其保持在尼龙壳或者其它类型的壳中,单个连接器典型地包括2、、4、5、6、9、12、或者15个管脚和插座对,每对代表不同的电子电路。管脚和插座能够以各种可能的组合安置在单个连接器中并且壳体典型地分为公和母部分。AMP(现在为Tyco电子公司)开发了MATE-N-LOK.084管脚连接器,其原来用在磁盘驱动上。该互连构型现在被制定为用于磁盘驱动电力连接器的标准。
尽管其被广泛采用,但是MATE-N-LOK连接器系统具有某些缺点。例如,在使用时,管脚和插座式触头在连接器系统的壳体部分内会经受不稳定的保持。壳体内的不稳定的保持会导致连接器部分或者完全失效,结果导致连接器所结合到其中的装置的性能降低甚至失效。这样,对于能够提供在连接器壳体内的更稳定和可靠的保持的管脚和插座,存在一种持续的需求。如果一个或多个触头已经被错误布线,触头通常从壳体部分移除用于再次布线。专门设计的工具可以用来从壳体部分拔取管脚和/或插座。因此,待解决的问题是对提供在连接器壳体内的稳定且可靠的保持并且必要时能够从壳体容易地拔取的管脚和插座的持续需求。
发明内容
通过提供一种用于电子元器件的电触头而提供一种解决方案。该连接器触头,其可以是管脚式触头或者插座式触头,包括与主体部分一体形成的缆线保持部分和配合部分。触头的主体部分还包括至少一个且典型地为两个向外偏压的锁闩,这些锁闩的每一个适于有效地接合连接器壳体的内部,也就是触头腔,以及拔取工具,如果必要的话。每个锁闩由相同的材料形成为触头的主体部分并且与其一体形成并进一步包括内部偏压件和形成在偏压件的末端的外部接合件,用于摩擦接合壳体和拔取工具。内部偏压件包括向下倾斜部分和向上倾斜部分,而外部接合件包括第一倾斜部分和第二倾斜部分。
对于本领域技术人员来说,本发明的其它特征和方面将通过阅读和理解下面的示例性实施例的详细描述而变得明显。如本领域技术人员将认识到的,本发明的其它实施方式也是可能的,而不超出本发明的范围和精神。相应地,附图及相关描述在本质上应视为示例性的而非限定性的。

具体实施方式
现参照附图描述本发明的示例性实施例。在整个详细描述中附图标记用于表示各个部件和结构。在其它的情形下,熟知的结构和装置以方框图形式示出以为了简化描述。尽管下面的详细描述包含许多特定细节以用于示例目的,但是本领域技术人员将认识到,可以在本发明的范围内对下面的细节进行许多改变和变更。相应地,本发明的下面的实施例不失任何一般性地被提出,并且也不对要求保护的发明构成限制。
本发明涉及一种连接器系统,其包括连接器壳体部件和安装在壳体部件内部的管脚和插座式触头。本发明的第一一般实施例提供一种连接器系统,其包括:管脚式触头和插座式触头,管脚式触头和插座式触头每一个包括至少一个接合/保持锁闩;本发明的第二一般实施例提供单个电触头,其包括至少一个接合/保持锁闩;本发明的第三一般实施例提供一种用于有效地从连接器组件的壳体部分拔取电触头的方法。现将参照附图更详细地描述本发明的一个或多个特定实施例。
现参照附图,图1提供现有技术的管脚式触头的数个视图,该管脚式触头不包括本发明的特征,图2-7提供根据本发明的示例性MATE-N-LOK管脚式触头的多个示例性视图。如图2-7所示,管脚式触头110包括插座配合部分120、中空长型主体124和缆线保持部分130。插座配合部分120包括圆形末梢122,其适于插入到作为标准的MATE-N-LOK系统或者类似的管脚和插座配合系统的一部分的相应的MATE-N-LOK插座中。缆线保持部分130适于接收一定长度的部分剥皮的缆线并包括缆线筒、定位槽和绝缘筒。缆线筒包括第一和第二凸片132和134,定位槽包括第一和第二凹口136和138,绝缘筒包括第一和第二凸片140和142。在使用中,凸片132和134围绕缆线的剥皮部分卷曲并且凸片140和142围绕相同缆线的绝缘部分卷曲。管脚式触头110典型地制造在具有其它管脚式触头的载体条上。该载体条的部分144示出在图中。
如图6-7最好地示出,第一和第二向外偏压接合/保持锁闩150和160形成在主体124靠近末梢122的任一侧上。锁闩150包括内部定位锥形(见图3)偏压件152和从主体124突起通过开口156的倾斜接合件154。同样地,锁闩160包括内部定位锥形偏压件162和从主体突起通过开口166的多角度接合件164。锥形偏压件152和162总体上增大其弹性。在示例性实施例中,锁闩150和160都与主体124一体形成并用与主体124相同的材料形成,该材料典型地为导电金属。管脚式触头110通常由一片金属冲压并碾压成其最终的形状。偏压件152和162,其大致径向偏压的,分别提供弹簧装载效果到接合件154和164,从而提高接合件154和164接合连接器壳体的内部也就是接触腔(见下面)以及如果必要的话拔取工具的能力。偏压件152和162典型地在碾压之前形成在主体124中,部分的偏压件152和162可以被剪切以产生接合件154和164。
如图8所示,锁闩250和260也可包括在插座式触头210上。如图8所示的插座式触头210的示例性实施例包括与管脚式触头110相同的基本结构特征;但是,配合部分220的末梢222包括插座(而非圆形末梢),其适于接收管脚式触头110用于与其建立电连接(见图11)。插座式触头210在配合部分220中包括中空长型主体224和缆线保持部分230。缆线保持部分230适于接收一定长度的剥皮缆线并包括缆线筒、定位槽和绝缘筒。缆线筒包括第一和第二凸片232和234,定位槽包括第一和第二凹口236和238,绝缘筒包括第一和第二凸片240和242。在使用中,凸片232和234卷曲在缆线的剥皮部分周围,凸片240和242卷曲在相同缆线的绝缘部分周围。第一和第二向外偏压接合/保持锁闩250和260形成在主体224在末梢222附近的两侧上。锁闩250包括内部定位锥形偏压件252和从主体224突起通过开口256的倾斜接合件254。同样地,锁闩260包括内部定位锥形偏压件和从主体224突起的多角度接合件264。在示例性实施例中,锁闩250和260都与主体224一体形成,并且用与主体224相同的材料形成,该材料典型地为导电金属。插座式触头210典型地通过使用与上述管脚式触头110相同的基本方法制造。
如前所述,管脚式触头110和插座式触头210意在用于包括在电子装置中的连接器系统。这样的连接器系统典型地包括连接器组件,该连接器组件进一步包括多个壳体部件。在一些连接器系统中,这些壳体部件称为插塞壳体300和盖壳体302(见图9-11)。每个壳体部件典型地包括形成在其中的至少一个触头腔304,用于接收管脚式触头110或者插座式触头210。当管脚或者插座式触头被插入到触头腔(从壳体部分的后侧)中时,所述锁闩接合触头腔的内表面并牢固地将触头保持在那里。所述接合件典型地长于包括在现有技术的管脚(见图1)上的矛状结构并总体上提供更大的弹性用于接合触头腔。如图6所示,锁闩150和锁闩160的部分153和163分别向后靠或者抵靠定位主体124的不是任一锁闩的一部分的部分。该构型提供额外的结构支撑到锁闩150和160,从而防止锁闩通过它们自身向后折叠,并且减小触头在使用过程中被意外地从壳体拔出的可能性。对于插座管脚210上的锁闩250和260同样如此。
再者,如前所述,锁闩(150和160或者250和260)有利于在管脚已经被错误布线和/或插入到错误的触头腔中的情形下管脚式触头110或者插座式触头210从触头腔移除。拔取工具306(见图10)典型地用于从触头安装所在的壳体部件移除触头。拔取工具306插入到触头腔(从壳体的前侧)中以使得拔取工具的圆柱套筒部分延伸超过触头的末梢并接合锁闩。随着圆柱套筒在锁闩上移动,套筒的向前运动径向向内地下压锁闩,从而迫使锁闩后退到主体中,从而从触头腔释放触头。在此所述的示例性实施例中,用于每个锁闩(150,160,250,260)的“4弯曲”设计分别允许接合件(154,164,254,264)的更大的径向偏转(以及更少的轴向偏转)。该4弯曲构型在每个锁闩上产生四段不同的部分或者区域,如本领域技术人员将认识到的,与更简单的设计也就是2弯曲设计相比,该4弯曲设计降低了触头的正确插入和保持中引入的误差。此外,接合件的相对浅的角度总体上为拔取工具306接合提供更大的表面积。当套筒抵达壳体部件的底部时,操作者释放在套筒内部保持弹簧装载实心活塞(spring-loaded solid plunger)的拔取工具上的控制杆。在拔取工具上的进一步的向前推进抵靠着触头的末梢推动实心活塞,同时锁闩仍被压下,从而将触头向后推出触头已经插入在其中的壳体部分。在本发明的其它实施例中,利用锁闩结构的一定程度的简化版本,其中在每个锁闩中的其中一个“弯曲”被去除。
