【具体实施方式】
为便于更好的理解本发明的目的、结构、特征以及功效等,现结合附图和具体实施方式对本发明作进一步说明。
如图6所示,本发明芯片模块连接装置包括一芯片模块4、位于芯片模块4下方的一电连接装置100及位于电连接装置100下方的一电连接器300。芯片模块4设有多个焊垫40;电连接装置100包括一绝缘本体1、插入所述绝缘本体1的多个端子2、收容于所述端子2中的锡球3,所述锡球3用以与所述芯片模块4的焊垫40相焊接;所述电连接器300包括一塑胶主体5及收容于塑胶主体5中的多个对接端子6。
如图2、4、5所示,所述绝缘本体1设有多个收容孔13,所述绝缘本体1具有相对的一上表面11和一下表面12,所述收容孔13贯通所述上表面11和所述下表面12,所述收容孔13具有一挡止部131连接所述收容孔13的相对两侧, 所述挡止部131的顶面与所述上表面11平齐且所述挡止部131的底面1310未延伸至所述下表面12。所述挡止部131具有一第一挡止面132位于所述锡球3一侧且挡止所述锡球3,所述绝缘本体1设有一让位空间133贯通所述上表面11和所述下表面12,所述让位空间133与所述收容孔13连通,所述让位空间133与所述第一挡止面132位于所述挡止部131相对两侧。所述收容孔13一侧壁自其顶端向下凹陷形成一第二挡止面134,所述第一挡止面132与所述第二挡止面134均为与所述锡球3匹配的弧面且至少一部分位于所述锡球3的水平中心面以下以增大所述第一挡止面132、所述第二挡止面134与所述锡球3的接触面积。所述收容孔13相对两侧设有倾斜的两定位部135。
如图1、2、4所示,所述端子2具有一连接部21,所述连接部21相对两侧具有两斜面211沿自上而下的方向相互靠近,所述斜面211与所述定位部135平行,所述定位部135位于所述斜面211向下位移路径上,使得所述定位部135挡止所述端子2向下移动,所述定位部135与所述斜面211之间具有间隙,使得所述定位部135与所述斜面211为松配合,从而所述端子2可在所述收容孔13中向下活动一定距离。自所述连接部21向上延伸有两臂部22及一挡块23,所述挡块23低于所述两臂部22且自所述两臂部22之间向下撕裂形成, 一收容槽24形成于所述两臂部22之间且高于所述挡块23,所述收容槽24具有一内面241,所述内面241为与所述锡球3匹配的弧面。所述挡块23沿自上而下的方向向所述挡止部131倾斜,从而所述挡块23顶面有一部分位于所述两臂部22之间形成一抵挡部231以向上挡止所述锡球3,所述挡块23顶面还有一部分凸出于所述臂部22的板面而形成一凸部232,所述挡止部131位于所述凸部232向上位移路径上,使得所述挡止部131的底面1310挡止所述凸部232向上移动,所述挡止部131的底面1310与所述凸部232之间具有间隙,使得所述挡止部131与所述凸部232为松配合,从而所述端子2可在所述收容孔13中向上活动一定距离,所述挡块23顶面为弧面,所述弧面的上缘L为与锡球3匹配的弧线。自所述连接部21向下延伸有一插接部25向下伸出所述收容孔13,以插入所述电连接器300的塑胶主体5中且被对接端子6夹持,所述插接部25末端设有一倒角251,便于所述插接部25向下插入所述塑胶主体5中(如图6)。所述连接部21、两臂部22、所述插接部25均呈平板状且位于同一平面。
如图2所示,当所述端子2从上往下插入所述收容孔13的过程中,所述挡块23与所述挡止部131的第一挡止面132干涉,使得所述挡止部131进入所述让位空间133且发生弹性变形,减小所述绝缘本体1受到的力,当所述挡块23向下越过所述第一挡止面132时,所述挡止部131弹性回复而恢复原状,从而所述挡止部131位于所述凸部232的上方且挡止所述凸部232向上移动。
如图3、5所示,所述锡球3收容于所述收容槽24,所述锡球3既被所述两臂部22挡止,也被所述第一挡止面132和所述第二挡止面134挡止,所述第一挡止面132与所述第二挡止面134位于所述收容槽24相对两侧,所述锡球3同时也被所述抵挡部231向上挡止。
综上所述,本发明的电连接装置100及芯片模块连接装置具有下列有益效果:
(1) 由于所述两臂部22之间形成收容槽24收容锡球3,所述挡块23自所述收容槽24向下撕裂形成,故便于所述端子2成型;同时,所述挡块23与所述挡止部131之间具有间隙,从而所述挡止部131挡止所述挡块23时为松配合,故所述端子2不会硬挤所述绝缘本体1,减小所述绝缘本体1所受应力,防止在锡球3焊接过程中所述绝缘本体1翘曲变形。
(2)所述锡球3既被所述两臂部22挡止,也被所述第一挡止面132和所述第二挡止面134挡止,使所述锡球3具有较好的共面度,保证了所述锡球3与所述芯片模块4焊接良好。
(3)所述收容孔13具有一让位空间133位于所述挡止部131一侧,当所述端子2从上往下插入所述收容孔13时,所述挡块23与所述挡止部131干涉,使得所述挡止部131进入所述让位空间133并发生弹性变形,减小了所述绝缘本体1受到的力。
(4) 所述端子2对应焊接于所述焊垫40,由所述绝缘本体1和排设于所述绝缘本体1中的多个所述端子2,取代传统技术中的芯片模块4上的高成本的圆形插针,容设于所述绝缘本体1中的多个所述端子2焊接至所述芯片模块4时,不需像传统技术中的所述圆形插针一根根进行组装,过程简单且节省工时;所述端子2是由板材冲压而成,其制造成本低,节省了相应的生产成本;当所述端子2损坏时,维修较为简便;多个所述端子2于所述绝缘本体1中小间距排列,有利于实现多个所述端子2在所述芯片模块4上的小间距排列。
以上详细说明仅为本发明之较佳实施例的说明,非因此局限本发明之专利范围,所以,凡运用本创作说明书及图示内容所为之等效技术变化,均包含于本创作之专利范围内。
