Description

電連接器及其組合
本發明涉及一種電連接器,尤其涉及一種可實現晶片模組與電路板間電性連接之電連接器。
中國大陸專利公告第1252882號揭露了一種連接晶片模組至電路板之電連接器,所述電連接器包括絕緣本體以及與絕緣本體安裝固定之下蓋。當將電連接器連接於電路板上時,先將絕緣本體焊接於電路板上,然後將下蓋從上往下安放於底座上並相互卡持固定,從而完成電連接器與電路板間之連接。
然而,隨著電連接器小型化之發展趨勢,絕緣本體之尺寸不斷減小,導電端子之排列密度不斷增加,如此使得當將絕緣本體焊接至電路板上時,導電端子與電路板上之金屬觸點之精準對位產生困難,而且由於絕緣本體之尺寸之減小,會使得絕緣本體之強度不足,不能滿足電性連接之需求。
鑒於此,確有必要提供一種改進之電連接器,以克服先前技術存在之缺陷。
本發明之目的係提供一種小型化之電連接器。
本發明之電連接器可藉以下技術方案實現:一種電連接器,用以 連接至設有對位結構之電路板,所述電連接器包括:絕緣本體;導電端子,設於所述絕緣本體中;及金屬框體,用以將絕緣本體固定於電路板,所述金屬框體具有側邊,所述側邊圍設成一收容空間;其中所述金屬框體與所述絕緣本體以嵌入成型(insert molding)方式相結合,所述絕緣本體延伸入所述收容空間,所述金屬框體與電路板上之對位結構相對準以安裝於電路板上。
本發明之電連接器組合可藉以下技術方案實現:一種電連接器組合,用以與晶片模組電性連接,所述電連接器組合包括:電路板,其上設有複數金屬觸點;絕緣本體,安裝於所述電路板上;導電端子,設於所述絕緣本體中並與電路板上之金屬觸點對應連接;及金屬框體,與所述絕緣本體以嵌入成型(insert molding)方式相結合,所述金屬框體具有側邊,所述側邊圍設成一收容空間;其中所述電路板上設有圍設於金屬觸點周圍之對位結構,所述金屬框體與電路板上之對位結構對應安裝。
相較於先前技術,本發明電連接器組合之金屬框體與絕緣本體嵌入成型,電路板上設有與金屬框體採用同一製造基準形成之對位結構,可保證電連接器與電路板間之準確對位並增強絕緣本體之強度,滿足小型化連接器之電性連接需求。

請參閱第一圖、第二圖所示,本發明之電連接器組合100包括電路板6以及安裝於電路板6上之電連接器。所述電連接器包括絕緣本體1、設於絕緣本體1中之導電端子2以及與絕緣本體1嵌入成型(insert molding)之金屬框體3。
請重點參閱第三圖所示,所述金屬框體3呈矩形結構,其包括首尾相連之側邊31,所述側邊31圍成一收容空間30。所述金屬框體3還可以包括自側邊31向遠離收容空間30之方向延伸設置之外凸部310以及自側邊31向收容空間30內凸伸設置之內凸部311。於本實施例中,所述外凸部310和所述內凸部311係自金屬框體3之角落延伸設置。在其他實施例中,所述外凸部310或所述內凸部311也可以自金屬框體3之其他部位延伸。所述外凸部310和所述內凸部311可於電連接器安裝於電路板6上時起防呆作用,防止錯誤安裝,亦可增大兩者安裝時之接觸面積,增強連接可靠性。
所述絕緣本體1與所述金屬框體3係為嵌入成型,所述絕緣本體1延伸入所述金屬框體3之收容空間30內。所述絕緣本體1所覆蓋之面積小於所述收容空間30之面積,即所述絕緣本體1僅佔據所述收容空間30之其中一部份空間。於本實施例中,所述絕緣本體1係位於所述金屬框體3之一角落處。
請參閱第四圖、第五圖所示,所述導電端子2包括焊接部21以及自焊接部21傾斜向上延伸設置之彈性臂22,所述彈性臂22上設有 接觸部221。所述焊接部21用以電性連接至電路板6,所述接觸部221用以電性連接晶片模組。所述導電端子2除所述焊接部21之下表面以及所述接觸部221之上表面以外,其餘部分均塗敷有絕緣層。所述絕緣層可防止相鄰導電端子2之短接,滿足導電端子2高密度排列需求。
請參閱第二圖、第三圖所示,所述電路板6上設有複數金屬觸點60,用以與導電端子2對應接觸。所述電路板6上還設有圍設於金屬觸點60周圍之對位結構61,於本實施例中,所述對位結構61與所述金屬框體3是以相同構形設置於電路板6上,即所述對位結構61包括一大框,所述大框與所述金屬框體3之結構相同。在將電連接器安裝到電路板6上時,只需對準金屬框體3與電路板上的對位結構61便可將導電端子2準確定位在對應金屬觸點60上,減小兩者對位公差。所述對位結構61還可以包括位於大框內之小框,所述小框與所述絕緣本體1之周緣對應相同,所述絕緣本體1覆蓋所述小框圍成之區域。
所述電連接器係藉由黏膠4而黏貼於所述電路板6上。所述黏膠4貼附於所述金屬框體3之下表面上以及所述絕緣本體1之下表面周緣,所述黏膠4所形成之形狀與所述電路板6上之對位結構61之形狀對應相同。所述絕緣本體1以及所述金屬框體3藉由黏膠4對應黏貼於電路板6之對位結構61上即實現電連接器與電路板6間之連接。所述導電端子2藉錫塊或導電膠與所述金屬觸點60相連接。
本發明電連接器之絕緣本體1與金屬框體3以嵌入成型方式相結合,電路板6上設有與絕緣本體1以及金屬框體3對應之對位結構61,所述絕緣本體1以及金屬框體3與電路板6上之對位結構61採用 同一製造基準製造,如此只需對準金屬框體3與電路板上的對位結構61便可將導電端子2準確定位在對應金屬觸點60上,可減少導電端子2與電路板6上之金屬觸點60間的對位公差。而且金屬框體3嵌入成型於絕緣本體1上,可增強絕緣本體1之強度。
綜上所述,本發明符合發明專利要件,爰依法提出專利申請。惟,以上所述者僅為本發明之較佳實施例,本發明之範圍並不以上述實施例為限,舉凡熟習本案技藝之人士援依本發明之精神所作之等效修飾或變化,皆應涵蓋於以下申請專利範圍內。
