Abstract
一个用于PGA组件的电气接插件,提供以减小其高度。一个用于PGA组件的电气接插件包括一个箱板,其以栅格阵列型形成有适于接受PGA组件销钉的多个接触孔;多个安装于各个接触孔内的接线端;及一个外罩,其上以栅格阵列型形成有适于***销钉的通孔,可以滑动地安装于箱板的上面,每个接线端位于接触孔内,通过各个独立安装的适于与销钉电接合的弹簧接件和在从箱板底面压力下而接合的平行的接合片所构成。
Description
本发明涉及一种用于销钉栅格阵列(pin grid array,PGA)组件的电气接插件,用来连接以栅格阵列型配置有连接销钉的PGA组件(销钉栅格阵列组件,下面也简称为“组件”)于印刷电路板上等。
传统上,用于这种类型的组件的电气接插件,包括一个以栅格阵列型形成有适于接受组件销钉的多个接触孔的箱板,多个安装于各个接触孔内的接线端,以及一个外罩,其上以栅格阵列型形成有适于***销钉的通孔,且可以滑动地安装于箱板的上面。外罩作为以无插拔力将销钉***于接触孔内,在通过外罩的通孔将销钉***于箱板的接触孔后,外罩滑动以移动整个销钉栅格阵列,即组件,从而使销钉和接线端电接合(例如,见日本专利号2689325)。
每个接线端形成焊接尾翼装备在焊接片的延伸处的结构,经由接合部位接合每个销钉于箱板上。这个焊接尾翼通常形成销钉形状结构以适于浸入焊接。
对于典型用于PGA组件的电气接插件,每个接线端形成如下结构,其中接触片、接合部位和焊接尾翼如前所述连接于一条直线上。因此,使接线端很长,使得箱板的厚度类似于接触片和接合部位的长度,导致出现整个电气接插件高度降低很困难的问题。
本发明致力于解决上述问题,即,本发明的目的是提供一种用于PGA组件的、具有适于降低高度的结构的电气接插件。
为完成上述目的,本发明的设想结构,其中的用以接合于箱板上的接触片和接合片,以平行结构取代以往接线端其中的直线排列结构。
一个用于PGA组件的电气接插件包括:
一个箱板,具有多个栅格阵列型接触孔适于接受PGA组件的销钉;
一个外罩,其上以栅格阵列型形成有适于***销钉的通孔,且可以滑动地安装于箱板的上面;及
多个安装于各个接触孔内的接线端,每个位于接触孔内的接线端,由各个独立设置的适于与销钉电接合的弹簧接件和在从箱板底面的压力下而接合的平行接合片所构成,所说的弹簧接件和所说的接合片以朝向所说的外罩的相同方向伸出。
根据本发明的用于PGA组件的电气接插件,每个接线端由各个独立设置的弹簧接件和平行的接合片构成。因此,可以在没有减损弹簧接件的有效弹性长度的情况下,缩短接线端的长度,以及箱板也可做成薄断面的。
下面将通过参考本发明实施例的附图的详细说明从而更清楚的了解本发明,但这并不是一种限制,而仅仅是为了方便理解。

图2是根据本发明的优选实施例的箱板的顶部平面部分放大图;
图3是安装于印刷电路板的优选实施例的PGA组件的电气接插件的部分放大截面图;

图5是显示操作杆的操作部分位于落下位置时,外罩相对箱板和接线端的相对位置;
图6是显示操作杆的操作部分位于升起位置时,外罩相对箱板和接线端的相对位置;
本发明下面将参考附图对本发明实施例进行详细的讨论。在下面的描述中,将进行许多特别细节的阐述,以便彻底了解本发明。显然,对于那些熟悉本工艺的人来说,不需要本发明的这些特别细节的描述即可操作。另外,对于一些众所周知的结构没有详细显示,以避免不必要使本发明难理解。
图1显示优选实施例的PGA组件的电气接插件的分解的情况。安装的情况如图4。PGA组件电气接插件1包括一个箱板2,安置于箱板2上的接线端3,一个位于箱板2的顶面上的外罩4。
箱板2由介电塑料模制成,是一个在平面图上呈四面体形的薄板。用以滑动外罩4的控制杆5的安装部位6沿着箱板的后缘形成。穿过箱板2的接触孔7以栅格阵列型形成布满在另一部分的整个区域。如图2所示,以栅格阵列型形成的接触孔7与相邻排偏置半个栅距(在图2的横向方向)。它们整个以交错方式设置。按照这种安排,使得图2所示的距离A可以尽可能的缩短(例如1.27mm)。
接线端3安插于每一个接触孔7内。接线端3是由金属板冲压形成,其包括一个由底件8和一对接触片9组成的通常为U形的弹簧接件10,及从底件8一边伸出平行于接触片9的接合片11。每一个接触片9的远端向内***形成接触片9a。另外,焊接尾翼12从底片8的另一端伸出,平行于底片8的底边。如图3所示,它适于使表面被焊接到印刷电路板13的表面上。
在箱板2的底面2a中,沿着接触孔7的列,靠近接触孔7形成对应接合片11的接合孔14(见图3)。每一个接线端3安装于箱板2的底面2a,并在接合片11和接合孔14之间的压力下接合固定。接合片11被定位于相对接线端3的弹簧接件10的列的前方。接触孔7被形成适于冲孔,其中外罩4在列的前方滑动。结果,安装于箱板2上的每一个接线端3的弹簧接件10被定位于每一个接触孔7的一面,且在每一个接触孔7的另一面设置一个用于通过无插拔力***组件(未显示)的各个销钉15(见图2,5和6)的空间。
另外,外罩4被制成大小与图中所示的箱板2类似的四角形板结构。在优选实施例中,外罩4由金属片构成(铝,不锈钢或等等)。形成外罩4的边缘部分,其截面应该象图1所示形成槽形结构,或者边缘部分象图4所示的截面一样形成反向的L形结构,用以接合箱板2的边缘,它适于通过操纵操作杆5牵引外罩4沿箭头16的方向滑动。
操作杆5的接合部位17形成于外罩4后缘的反面。在外罩4的整个区域,以栅格阵列型的通孔18形成对应于箱板2的接触孔7。通孔18适于***组件的销钉15,并由表面的锥口孔19和底面的直孔20结合形成。外罩4的后缘部分由铆钉22固定的加强杆21所构成,如图1。然而,在图4中它构成一个整体模制结构。形成外罩4的金属片被镀上一层绝缘镀层如氧化膜等镀层,以防止***通孔18中的销钉15导电。
如图1所示,一个曲柄23和操作部分24连接形成L型结构而构成操作杆5。曲柄23的中心段被***在箱板2的安装部位6中,相对的面末端部分被***在外罩4的接合部位17上的延伸孔25中。参考数26代表止动环。按照图4的箭头27所指方向升高或降低操作杆5的操作部分24,外罩4可以沿箭头16所示方向前后滑动。这个滑动方向始终与接触孔7和接线端3的列一致。
如前所述,多个通孔18以栅格阵列型形成于外罩4上。然而,在通孔必须形成的部分,有一些部分留下空白28而没有形成栅格阵列型通孔。另外,没有形成接触孔7的部位29也留在与空白28部位对应的箱板2上。在没有接触孔形成的每一个部位29的底面2a上,形成一个如图2和3所示的***30。顺应钉31的钉端32在压力下与底面2a的每一个***30接合,顺应钉31从箱板2的底面2a***。
图3显示前述PGA组件的电气接插件的优选实施例被安装于印刷电路板13的情况。每一个从箱板2的底面2a***的顺应钉31与印刷电路板13上的接合孔33接合。在与其联合处,沿箱板2的底面2a以交错方式设置的接线端3的焊接尾翼12被焊接到印刷电路板13的电路焊接点上(未显示)。
图5和6显示,在操作杆5的操作部分24升起和落下位置时,外罩4相对箱板2和接线端3的相对位置。即,图5是显示操作部分24落下时的情况。外罩4沿箭头16a所示位置,滑动到接线端3的弹簧接件10与外罩4上的通孔18相配的位置上。图6是显示操作部分24升起时的情况。外罩4沿箭头16b所示位置,滑动通孔18到与弹簧接件10的面对应的位置。
当组件经由PGA组件的电气接插件连接到印刷电路板13上时,在操作杆5的操作部分24升起后,组件放置于外罩4上,销钉15经由外罩4的通孔18***在接触孔7中。每一个销钉15***即将以无插拔力***的接线端3的弹簧接件10的面。
下一步,当操作杆5的操作部分24在落下位置时,外罩4沿图5的箭头16a所示位置滑动。相应地,销钉15和整个组件沿相同方向滑动,从而使每一个销钉15都移动到对应接线端3的弹簧接件10的位置。结果,销钉15与即将导电的接触片9的触点部位9a接合,经由接线端3将它们设置为连接到印刷电路板13的电路上的情况。
每一个接线端3由各个独立设置的弹簧接件10和平行的接合片11形成。因此,接触片9可以通过限定整个长度大致与箱板2的厚度相同为有效弹性长度,而获得弹性性能,并在销钉15之间建立确定的电导。
另外,由于接触片9的有效弹性长度的整个长度可以制成与箱板2的厚度相似,接触片9的长度和箱板2的厚度可以减少到能够提供导电的弹性性能的必须长度。因此,可以达到减小组件1的电气接插件高度的要求。另外,通过缩短接触片9的长度,接线端3的电感应可以减小从而有助于高速信号传导。值得注意的是,金属片构造的外罩4也可有助于组件1的电气接插件高度减小,因为外罩4可以提供一般外罩的足够强度,即使它仅仅由很薄的片构成。
当组件1的销钉15如前所述在操作杆5的操作下在接线端3的弹簧接件10的面上移动时,应力在相对于接线端3和箱板2的滑动方向发生。与印刷电路板13接合的顺应钉31可以抵抗这种应力。
由此,可以防止由于作用于接线端3的焊接尾翼12的焊接部位的过大应力,所导致如焊接部位的的剥离等等的不完全连接。
在释放组件连接的情况下,操作杆5的操作部分24将被升起。当操作部分24被升起时,销钉15沿图6的16b的箭头所示方向滑动到弹簧接件10的一侧,从而不需用很大的拉出力将组件拆下。同样,顺应钉31可以保护焊接尾翼12的焊接部分。
在前述优选实施例中,每一个接线端3的接触片10整体上由底件8和一对接触片9构成U型结构,但并不仅限于此结构。它也可以由贴紧每个销钉15于其上的一个接触片构成。
如前所述的优选实施例中,每个销钉15都被夹紧在一对接触片9加紧的结构中,在外罩4滑动所致的应力和建立确定导电所致的电导情况之间没有关系。
另外,每个接线端3的焊接尾翼12也不限于适于表面焊接的结构。销钉形状的焊接尾翼可以***印刷电路板13的通孔中,通过浸入焊接的方法焊接。顺应钉31的安装密度设定由滑动外罩4产生于接线端3和箱板上的应力来加以考虑。它的密度以接线端3的安装密度的十分之一的密度分布被认为是合适的。
在上述结构中,因为各个接线端均由各自独立的弹簧接件和平行的接合片形成,接线端的长度可以缩短,通过给每个弹簧接件提供在组件的销钉之间产生必要电导程度的有效弹性长度,还可以做成薄断面的箱板。因此可以达到减小PGA组件电气接插件的高度。
组件的每个销钉由一对接触片夹紧产生一定的电导。
另外,通过表面焊接提供适于安装于印刷电路板上的PGA组件的电气接插件成为可能。再者,顺应钉可以抵抗由于滑动外罩而产生在接线端和箱板上的应力,以保护焊接尾翼的焊接部分。
尽管本发明已经参考实施例进行了描述和说明,熟悉本工艺的人应该理解,只要不背离本发明的精神和范围下,进行的前述的和其它变化、这儿或那儿的省略和添加都是可以的。因此,本发明不应该被理解为仅限于上述的实施例,而是包括符合下面所附的权利要求限定的范围内的所有实施例。
