Description
【技术领域】
本实用新型是有关一种插座连接器,尤其是指一种电性连接平面栅格阵列芯片模组与电路板的插座连接器。
【背景技术】
随着计算器技术向小型化的方向发展,平面栅格阵列(LGA)插座连接器也随之向越来越小的方向发展,其一般包括绝缘本体和若干端子。由于,当端子与一个对接的电子元件(比如中央处理器)的电极相结合时,其间会产生很大的压力,并且,由于端子的尺寸很小,所以在其中的弹性接触臂很容易被损坏。对于上述问题,已有几种解决方法。一种解决方法揭示于美国专利第6315576和6290507号中,这种现有技术的端子构造要经过改造以获得端子弹性接触臂最佳的电气和机械性能。另一种解决方法揭示于美国专利第6186797号中,这种现有技术要改造端子与插座连接器间的排列方式。第三种解决方法揭示于美国专利第6186797号,该插座电连接器其基座的端子孔排列成阵列状,用于收容端子于其中。每排端子孔相对于绝缘本体边缘有相同的导向角,较好的是与基座侧边成45度角。通过此方案,不仅可使相邻端子间之间距最小,而且端子性能也得以改善。但是,同时,由于存在现有端子制造技术的限制,导致端子不能完全充满基座的端子孔。因此,端子的组装过度复杂,而且,由于端子孔导向角为45度设置,因而基座模具的型芯也应为45度设置,从而增加了基座模具形状的复杂度。
有鉴于此,确实有必要设计一种其端子可以和电子元件的电极可靠电性连接,而且还很容易将端子组装进其端子孔的插座连接器。
【实用新型内容】
本实用新型的一个主要目的在于提供一种具有导电端子的插座连接器,在仍保持插座端子的高密度排列的情况下,又可使其具有较佳的机械和电气特性。
本实用新型的目的是这样实现的:提供一种插座连接器,其可连接平面栅格阵列(LGA)芯片和印刷电路板(PCB)。一种较好的实施方式是:该插座连接器包括:绝缘本体,绝缘本体内设有多排端子收容单元,端子成排组装于端子收容单元中,其中,端子设有沿预定方向延伸的弹性接触臂,其可从最初位置偏移至最终位置,同排中两邻接的弹性接触臂在最初位置设有第一垂直距离,在最终位置设有第二垂直距离,第二垂直距离小于第一垂直距离,端子弹性接触臂向远离收容该端子的端子收容单元延伸并占据固持邻接端子的端子收容单元上方的空间,且上述邻接端子的弹性接触臂部分位于此端子弹性接触臂的下方。
与现有技术相比,本实用新型具有以下优点:当弹性接触臂和LGA芯片的电极结合时,相邻弹性接触臂间相互重叠,且各弹性接触臂足够长以提供完好的弹性偏移特性,因而确保弹性接触臂和电极间很好的机械电气连接。

【具体实施方式】
请参阅图1至图4所示,本实用新型一种较好的实施方式是:一种插座连接器,包括若干从一片弹性金属材料冲压而来的端子1。该端子1包括定位板10,弹性接触臂12和连接定位板10和弹性接触臂12的桥部11。其中定位板10连接到料带上(未图示),以使端子1容易成排插入插座连接器。该定位板10的两相对边缘上突出有一对下方凸刺101,及位于下方凸刺101的上方,并设于该定位板的一个侧缘上的上方凸刺100。下方凸刺101和上方凸刺100用于将端子固持于插座连接器内。桥部11从定位板10的另一侧边横向延伸。弹性接触臂12包括伸长的上连接部120和下连接部121,其中上连接部120从桥部11横向向上延伸,以和LGA芯片3(如图8所示)的相应电极31进行机械和电气连接。下连接部121凸出于桥部11以和PCB(未图示)的相应电路板进行机械和电气连接。上连接部120包括在其末梢端的接触部1200,用以和电极31接触。下连接部121包括在其末梢部的水平焊接基板1210,用以焊接到PCB板上。
请参阅图5,插座连接器的绝缘本体2,其包括分别与电子元件和电路板导接的接触端面与安装端面,并提供了若干端子收容单元,用以收容相应的端子。端子收容单元排列成规则的矩形阵列,其包括:后绝缘壁20,邻接于后绝缘壁20底部的第一保持区21,及邻接于后绝缘壁20底部并与第一保持区间隙分开的第二保持区22;其中第一和第二保持区21,22之间的部分为通道26。在邻接于通道26的第一和第二保持区21和22上,有一对下固持部23,用以和相应端子1的下方凸刺101干涉配合。在相应的下固持部23上方的第二保持区22上,设有上固持部24,用以和端子1的上方凸刺100干涉配合。
请参阅图6至图9,插座连接器组装时,一排端子1的相邻接定位板10已连接在料带上,这排端子1通过料带被装载进相应端子收容单元。而且,所有的端子1都如此插入到绝缘本体2的相应端子收容单元。任何两个邻接的定位板10之间的距离是确定的常数。两相邻端子收容单元间的距离是确定的常数。因此,每两个相邻安装的端子1间的间隙也是确定的常数。端子1如此排列以使端子1的上连接部120有一个沿端子收容单元排列方向延伸的距离A。每两个邻接的定位板10间有一段距离B,距离A比距离B要长。每两相邻的通道26间有一间隙25。端子1的上连接部120穿过间隙25延伸,而且在第二个邻接的间隙25上进一步延伸,所以端子1的上连接部120设置于邻接端子1的弹性接触臂12的上方,相邻端子之弹性接触臂间隙设置,且彼此平行。同排中端子1的上连接部120是彼此平行的,上连接部120的接触部1200位于相邻端子1下连接部121的上方。因此,当端子1和LGA芯片3的电极31结合时,上连接部120足够长可以提供很好的弹性偏移特性,确保弹性接触臂12和电极31间好的机械和电气连接。
请参阅图8,使用插座连接器时,LGA芯片3置于初始位置。插座连接器绝缘本体2中设有收容LGA芯片3的接收槽27。在初始位置,LGA芯片3置于插座连接器绝缘本体2的接收槽27中。端子1的接触部1200和LGA芯片3的相应电极31各自松弛接触。上连接部120彼此平行,而且弹性支撑其上部的LGA芯片3。每两个邻接的上连接部120间的垂直距离为第一垂直距离C。
图9所示为LGA芯片3被外力下压时的情形。LGA芯片3的电极31对于上连接部120有一个向下的弹性偏移。当LGA芯片3抵达最终的结合位置时,上连接部120仍然彼此间隙隔开,而且彼此平行。每两个相邻上连接部120间的垂直距离为第二垂直距离C’,其小于距离C。
端子1的弹性接触臂120在来自于LGA芯片3的外力下从初始位置偏移到最终位置。由于上连接部120的伸长结构,在增大施加力时,它们会均一稳定的偏移。因此,LGA芯片3可以在初始位置时置于连接部120的接触部1200上,而且被稳定增长的力下压到最终位置以可靠的建立与端子1的电性连接。这增加了仍保持高密度端子插入时插座连接器的性能。从而,在LGA芯片3和端子1之间可达到稳定可靠的电性连接。
