Description

电连接装置 技术领域
本实用新型涉及一种电连接装置， 尤指一种在连接器的内金属壳体外部 再套设有外金属壳体， 继而焊固于电路板上的电连接装置。 背景技术
请参阅图 1 所示， 其示出了现有的电连接器如中国台湾实用新型 M276350(申请号 :094205123)专利， 其揭露出一第一外壳 11、 一第二外壳 12 及一端子座 13。 端子座 13上设有多个端子 14， 第一外壳 11包覆端子座 13， 且第一外壳 11的两侧壁各设有一定位部 111， 第二外壳 12的两侧壁则分别 设有一卡合件 121。通过卡合件 121可以卡合在对应的定位部 111，使得第二 外壳 12可以固定于第一外壳 11外侧，并且第二外壳 12左右各设有接脚 122， 其可穿设于电路板 (未示出)的穿孔， 使得电连接器可焊固于电路板。
然而， 上述的电连接器的第一与第二外壳以卡扣的方式组合， 彼此间并 未紧密固定。 所以电连接器与电路板在过锡炉欲焊接的期间， 第一与第二外 壳易因外力震动 (例如输送带运输时)而相互移位， 因此第二外壳的接脚必须 采用穿孔形式 (through hole type)的设计， 若改采用表面黏着技术形式 (SMT-TYPE)则易造成第二外壳的 SMT-TYPE接脚与端子的 SMT-TYPE的焊 接部不共平面， 而产生电连接器端子空焊的问题， 使信号传输不佳。 其次， 又因第一与第二外壳以卡扣的方式组合， 彼此间并未紧密固定， 因此第一与 第二外壳间隔有间隙， 这使得电连接器在与相匹配的对接连接器插拔时， 插 拔时产生的应力大部分仍由第一外壳所承受， 继而使端子的悍接部承受大部 分插拔的应力， 易使电连接器松脱， 即端子有松脱的情形。 另一方面， 因电 路板为多层板的结构设计，因此穿孔数量会影响电路板内部线路的走线配置， 故第二外壳为穿孔形式的接脚则会提升电路板在走线配置设计上的问题， 而 提升成本。
因此， 本创作人有感上述可改善的缺陷， 提出一种设计合理且有效改善 上述缺陷的电连接装置。 发明内容
本实用新型的目的在于提供一种电连接装置， 其使内外金属壳体能紧密 固定于一体， 可以确保过锡炉期间， 外金属壳体的焊片会与连接器端子的焊 接部共平面， 以改善端子易空焊的问题。 并且以焊片可焊固于电路板的板面 上， 能具有减少电路板上的穿孔数， 而改善其易影响电路板内部线路走线的 走线配置。
本实用新型的另一目在于提供一种电连接装置， 其使内外金属壳体能紧 密固定于一体， 以令对接连接器插拔吋产生的应力皆立即由内外金属壳体共 同承受， 而使连接器不易松脱。
为达上述所述目的， 本实用新型提供一种电连接装置， 其包含一连接器 与一外金属壳体。 连接器包括一绝缘本体、 多个设于绝缘本体的端子及一遮 蔽绝缘本体的内金属壳体， 每一个端子均具有一焊接部， 该焊接部形成有一 第一焊接面。 外金属壳体套设在内金属壳体外部， 其特征在于， 连接器的内 金属壳体具有一顶片， 外金属壳体具有一顶片， 内金属壳体的顶片及外金属 壳体的顶片以多个激光接点紧密固定为一体， 且外金属壳体的两侧分别具有 一横向的悍片， 所述焊片分别形成有一第二焊接面， 每一个端子的第一焊接 面与该焊片的第二焊接面共平面。
本实用新型具有以下有益技术效果： 通过将内外金属壳体的顶片以激光 接点紧密固定为一体， 改善彼此间并未紧密固定的问题， 以此确保过锡炉期 间， 外金属壳体的 SMT-TYPE的焊片与连接器端子的 SMT-TYPE的焊接部 共平面， 以改善端子易产生空焊的问题。并且外金属壳体以 SMT-TYPE的焊 片以焊固于电路板的板面上， 以此减少电路板上的穿孔数， 而改善其易影响 电路板内部线路的走线配置。 其次， 内外金属壳体的顶片以激光接点紧密固 定为一体，当对接连接器插拔时产生的应力皆立即由内外金属壳体共同承受, 继而使连接器不易从电路板上松脱。

内金属壳体 40具有相对的前端 401与后端 402，前端 401对应于绝缘本 体 20的前端 201，后端 402则对应于绝缘本体 20的后端 202。而内金属壳体 40具有一顶片 41、 两个连接于顶片 41两侧的侧片 42、 一连接于侧片 42底 部的底片 43及一连接于顶片 41后端 402的后盖 44。 内金属壳体 40还设有 侧面焊脚 45与后焊脚 46， 其中侧面焊脚 45分别自两个侧片 42向下延伸而 成， 后悍脚 46则自后盖 44底部近两侧向下延伸而成。 顶片 41在近前端 401 的近两侧则各设有一窗口 411，且顶片 41在窗口 411的前端 401分别设有一 突片 412， 顶片 41的近后端 402与近两侧还分别弯折设有挡片 413。
外金属壳体 5具有相对的前端 501与后端 502， 前端 501对应于内金属 壳体 40的前端 401，后端 502则对应于内金属壳体 40的后端 402。而外金属 壳体 5具有一顶片 51 , 且两侧具有两个侧片 52与两个横向的焊片 53， 侧片 52分别自顶片 51的两侧延伸，侧片 52末端分别弯折延伸形成焊片 53，悍片 53的底部分别形成有一第二焊接面 531。另一方面，顶片 51的前端 501还向 前延伸有一延伸部 511，延伸部 511的两侧分别形成有一让开凹口 512，并且 顶片 51的近后端 502两侧分别弯折延伸有一折片 513。
请再配合参阅图 4至图 6所示， 每一个端子 30均设于绝缘本体 20， 每 一个端子 30的接触部 31均位于舌板 22的一板面 (如图 3)，焊接部 32则位于 基体 21的底部。 内金属壳体 40遮蔽绝缘本体 20， 且内金属壳体 40形成有 一具有插口 471的插接空间 47，插口 471位于内金属壳体 40的前端 401，舌 板 22即位于插接空间 47内 (如图 5所示)。 内金属壳体 40的后盖 44盖设于 绝缘本体 20的基体 21后方。
外金属壳体 5套设在连接器 2的内金属壳体 40外部； 在本实用新型中， 内金属壳体 40的顶片 41与外金属壳体 5的顶片 51以激光焊接而形成有多个 激光接点 6(如图 4)， 以激光接点 6使内金属壳体 40的顶片 41与外金属壳体 5的顶片 51能紧密固定为一体。 并且外金属壳体 5的焊片 53的第二焊接面 531与每一个端子 30的焊接部 32的第一焊接面 321成共平面 (如图 6中的线 段 L所示：)。 另一方面， 外金属壳体 5的延伸部 511及内金属壳体 40的顶片 41亦以至少一个激光接点 6'紧密固定为一体， 以此可再加强内金属壳体 40 与外金属壳体 5紧密固定的效果。
另， 内金属壳体 40的顶片 41的挡片 413伸入于绝缘本体 20的凹部 23 中， 以挡止绝缘本体 20。 外金属壳体 5的折片 513则会插入于绝缘本体 20 的凹槽 24中，且止挡于内金属壳体 40的顶片 41的后端面。通过外金属壳体 5的折片 513止挡于内金属壳体 40的后端面，当对接连接器 (图未示)插入时， 能防止绝缘本体 20往后退。
上述外顶片 51的延伸部 511两侧的让开凹口 512位于内金属壳体 40的 内顶片 41的窗口 411上方， 以此， 当对接连接器 (图未示）自插口 471插入至 插接空间 47后， 对接连接器上的卡钩 (图未示)可弹性扣入于窗口 411与让开 凹口 512中而卡扣于突片 412。
请再复参图 2所示， 连接器 1与外金属壳体 5设于一电路板 7的一板面 701上，板面 701上设有多个第一焊垫部 71及两个第二焊垫部 72。每一个端 子 30的焊接部 32均设于相对应位置的第一焊垫部 71上，外金属壳体 5的焊 片 53则设于相对应的第二焊垫部 72上。 通过内金属壳体 40的顶片 41与外 金属壳体 5的顶片 51以激光接点 6紧密固定为一体，如此可以确保过锡炉期 间， 外金属壳体 5横向的悍片 53与连接器 2的端子 30的悍接部 32共平面， 确保焊接部 32的第一焊接面 321能悍固于第一焊垫部 71上， 以改善易产生 空焊的问题。 同时， 通过内金属壳体 40的顶片 41与外金属壳体 5的顶片 51 以激光接点 6紧密固定为一体， 当对接连接器 (图未示)插拔时， 产生的应力 皆立即由内金属壳体 40与外金属壳体 5共同承受，而防止连接器 2自电路板 7上松脱。此外， 由外金属壳体 5的焊片 53的第二焊接面 531焊固于第二焊 垫部 72上， 是采用 SMT-TYPE的焊固焊片， 因而可减少电路板 7上的穿孔 数量， 以改善其易影响电路板内部线路的走线配置。
另一方面，电路板 7的板面 701上还可设有两个第三焊垫部 73与至少一 个第四焊垫部 74， 且电路板 7还设有多个穿孔 751、 752， 穿孔 751、 752分 别设于第二焊垫部 72与第三焊垫部 73的位置处。上述内金属壳体 40两侧的 侧面焊脚 45穿设于相对应的第二焊垫部 72的穿孔 751，继而焊固于电路板 7， 内金属壳体 40的后焊脚 46则分别穿设于第三焊垫部 73的穿孔 752， 继而焊 固于电路板 7。 在本实用新型中， 内金属壳体 40的底片 43的底面与端子 30 焊接部 32的第一焊接面 321共平面，故内金属壳体 40的底片 43的底面近前 端 401可进一步地悍固于电路板 7的第四焊垫部 74上， 以此更加强连接器 2 固定于电路板 7上的稳固性。
另外，在本实施例中，两个第二悍垫部 72分别具有一焊片焊垫 721与一 焊脚焊垫 722， 设于第二焊垫部 72的穿孔 721则位于焊脚焊垫 722。 外金属 壳体 5的焊片 53焊固于焊片焊垫 721上，内金属壳体 40的侧面焊脚 45则穿 设于焊脚悍垫 722的穿孔 751。请再参阅图 7所示， 并请配合参阅图 2， 本实 施例中， 第二悍垫部 76分别为一焊垫， 进一步地说， 即为上述实施例的焊片 焊垫 721与焊脚焊垫 722相连而成为单一的焊垫。 另外， 上述两个实施例的 第一焊垫部 71、 第三焊垫部 73与第四焊垫部 74也分别为一焊垫。
经由上述的说明， 本实用新型通过将内外金属壳体的顶片以激光接点紧' 密固定为一体， 改善彼此间并未紧密固定的问题， 以此确保过锡炉期间， 外 金属壳体的 SMT-TYPE的焊片与连接器端子的 SMT-TYPE的焊接部共平面， 以改善端子易产生空焊的问题。 同时， 内外金属壳体的顶片以激光接点紧密 固定为一体， 当对接连接器插拔时产生的应力皆立即由内外金属壳体共同承 受， 继而使连接器不易从电路板上松脱。 再者， 外金属壳体是以 SMT-TYPE 的焊片以焊固于电路板的板面上， 以此减少电路板上的穿孔数， 而改善其易 影响电路板内部线路的走线配置。
然而， 以上所述仅为本实用新型的较佳可行实施例， 并非因此局限本实 用新型的范围，故凡运用本实用新型说明书及附图内容所做的等效结构变化， 均同理皆包含于本实用新型的范围内。
