一种电连接器的制造方法，其步骤为：首先，由板状金属料带上冲制若干个端子毛坯及与该端子毛坯位于同一平面的连接部，其中该连接部与端子毛坯电性相连；再者，采用插入式内模成型将绝缘本体覆于金属料带上、下表面，其中该绝缘本体设有与端子毛坯及连接部相对齐的开口；最后，通过工具自开口作用于端子毛坯及连接部而将端子毛坯弯折并露出绝缘本体上、下端面而制成与对接电子元件电性连接的端子，且将连接部从端子上分离以便端子间电性隔绝。

Description

电连接器的制造方法及其产品
本发明有关一种电连接器制造方法及其产品，尤其是指一种栅格排列(Land Grid Array；下称LGA)电连接器的制造方法及其产品。
LGA电连接器一大优点在于其与对接电子元件对接时，只需采用压接设备将其与对接电子元件进行压接即可实现二者间的电性连接，而不需任何焊接操作。相关现有技术可参考美国专利第5,820,389、5,395,252、5,380,210、4,793,814及5,324,205号案。在这些现有技术中，制造LGA电连接器通常首先分别制成一绝缘本体及若干个导电端子，而后将导电端子组固于绝缘本体相应的孔穴中。但是，该制造方法过于繁琐而不利于自动化方式的实施，因此增加了电连接器的制造成本。另，由于绝缘本体为刚性塑胶材料制成，其挠性甚小，因此电连接器绝缘本体接合面的平面度对于连接器与对接电子元件之间的连接品质起到至关重要的作用。
本发明目的在于提供一种LGA电连接器的制造方法及其产品，其中该LGA电连接器可采用自动化方式制造从而降低生产成本。
本发明的目的是通过以下步骤实现的：本发明电连接器的制造方法包括以下步骤：第一步.自扁平铜合金料带上冲制出若干个端子毛坯及连接部，其中该端子毛坯及连接部与金属料带位于同一平面。且每一端子毛坯具有一对自其纵长主体部横向延伸设置的翼部，而该连接部与端子毛坯电性连接；第二步.采用插入式内模成型将绝缘本体覆于铜合金金属料带上，并将该金属料带夹持于绝缘本体之间，其中于该绝缘本体上设有与翼部相对齐的若干个第一开口、与连接部对齐的若干个第二开口，及位于端子主体部上、下表面的构造；第三步.通过辅助工具穿过第一开口将端子翼部沿相应构造的轮廓弯折以形成电连接器的端子，其中该端子翼部的自由端位于其各自相应构造的上、下表面；第四步.通过辅助工具穿过第二开口将端子连接部自金属料带上去除而使端子间电性隔绝。
由本发明制成的电连接器，包括绝缘本体及若干组设为栅格状的端子，其中端子收容于绝缘本体中，每个端子具有设于中部的纵长主体部及与其相连的横向翼部，绝缘本体设有若干与端子主体部相对应的构造，其中端子翼部沿构造延伸设置且其自由端突出构造上、下表面以与对接电子元件电性连接，另外，绝缘本体上邻近各端子设有第一开口及第二开口。
与现有技术相比，本发明的优点为：本发明的绝缘本体可采用插入式内模成型包覆到金属料带上，其制造简便且利于降低生产成本；再者，本发明的绝缘本体为弹性材料制成，因此其能够保证导电端子与对接电子元件之间的稳固连接。
下面结合图示及实施例对本发明作进一步的说明。
图1为冲制有若干个端子及连接部的金属料带的立体图。
图2为通过插入式内模成型将绝缘本体覆于图1所示的金属料带并将料带夹持于绝缘本体中的立体图。
图3为本发明LGA电连接器的上视图。
图4为图3所示电连接器的底视图。
图5为图3所示电连接器的局部放大图。
图6为连接部末去除的电连接器端子的底视图。
图7为图6所示端子之一的局部放大图。
图8为为图3所示电连接器的上视图。
图9为图8沿IX  IX线的剖视图。
图10为图9部分的局部放大图。
请参阅图1所示，制造本发明LGA电连接器的方法如下：首先，自金属料带10(最好为铜合金料带)上一体冲制出若干个端子毛坯12及连接部14。其中该端子毛坯12及连接部14与金属料带位于同一平面。另，每个端子毛坯12包括一对翼部122、124，其中该翼部122、124自端子毛坯12中部纵长主体部126沿相对的方向横向延伸设置，每个连接部14则包括下端翼片142及上端翼片144，这些翼片连接主体部126及金属料带10，从而将端子毛坯12相互机械式电性相连，其中该下端翼片142及上端翼片144位于相应主体部126的纵向末端。然后，通过插入式内模成型将绝缘本体(最好为矽橡胶)包覆于金属料带10上表面16和下表面18并将金属料带10夹持于绝缘本体中，从而制成图2所示的半成品20。该半成品20包括金属料带10、上端绝缘本体层22及下端绝缘本体层24，其中该上、下绝缘本体层22、24设有若干个与端子毛坯12的翼部122、124相对齐的第一开口26及若干个对与连接部14的下端翼片142、上端翼片144相对对齐的第二开口28，其中第一开口26比第二开口28大。
然后，对半成品20进行弯折操作，采用辅助工具由第一开口26伸入而将端子毛坯12的翼部122、124弯折，如至图6至图10所示，每一右端翼部124沿上端绝缘本体层22的构造29的轮廓向上弯折设置，其中该绝缘本体层22设置于端子毛坯12主体部126的上端面。而该构造29包括倾斜面292及水平顶端面294。另，右端翼部124的自由端128弯折于顶面294之上。同样，每一左端翼部122沿下端绝缘本体层24的构造30的轮廓向上弯折，其中该下端绝缘本体层24设置于端子毛坯12主体部126的上端面。其左端翼部122的自由端恰位于构造30的底面32上。因此，通过弯折操作而将翼部122、124变为本发明电连接器的端子，自由末端128、129则用来与对接电子元件相对接以实现电性相连。
尽管在本实施例中，绝缘本体包覆于铜合金料带外围可采用插入式插入式内模成型，但是，凡本领域技术人员也可采用其它方法，例如上端及下端绝缘本体层22、24亦可单独制成，然后粘贴到金属料带10上而将金属料带夹持于其中。
最后，如图5所示，利用辅助工具自第二开口28伸入将半成品20端子毛坯12的连接部14上端及下端翼片142、144由金属板上去除，由此端子间电性隔绝，从而制成本发明电连接器。
另，此去除操作亦可选择性地保留若干个连接部14与金属料带10相连，由此端子间可相互电性相连而成为电连接器40的接地板。
