Description

为了提升电连接器资料传输、 供电与电磁屏蔽的品质， 现有的电连接器常需要在其绝 缘本体上设置大量不同功效的端子， 并在绝缘本体内部埋设一个屏蔽件以减低端子在传输 时的电磁干扰。

有关本发明的前述及其他技术内容、特点与功效，在以下配合参考附图的较佳实施例的 详细说明中， 将可清楚地呈现。
参阅图 1至图 3， 为本发明电连接器的第一较佳实施例。 该第一较佳实施例具体为一插 座连接器而适用于供另一对接连接器 7插入连接 (见图 9)。该电连接器 300包含一接合本体 100、 一固设于接合本体 100内的接地金属片 3(见图 5)、 一围绕接合本体 100的外屏蔽壳 体 4及一位于外屏蔽壳体 4内并装设在接合本体 100表面的内屏蔽壳体 5。
参阅图 4至图 6，接合本体 100包括彼此组合的一第一端子模块 1与一第二端子模块 2。 第一端子模块 1具有一第一绝缘件 1 1及多个埋设固定于第一绝缘件 1 1的第一端子 12。第 一绝缘件 11具有一第一基部 11 1、 一由第一基部 11 1前侧向前延伸出的第一舌板部 112及 两个向下面对于第二端子模块 2的第一固定机构 1 15。 第一舌板部 1 12具有一向下面对第 二端子模块 2的第一结合面】13及一相反于第一结合面 1 13的第一对接面 114。 第一端子 12固定于第一基部 1 11， 且前端由第一基部 11 1 向前延伸以形成一外露于第一对接面 114 的第一对接部 121， 而后端由第一基部 11 1 向外伸出以形成一用以焊接于一电路板 8的第 一焊接部 122(见图 7及图 8)。
第二端子模块 2与第一端子模块 1的结构相同而彼此呈 180度旋转对称。第二端子模块 2具有一向上组合于第一绝缘件 1 1的第二绝缘件 21及多个埋设固定于第二绝缘件 21的第 二端子 22。第二绝缘件 21具有一位置对应于第一基部 11 1的第二基部 21 1、一由第二基部 211的前侧向前延伸且位置对应于第一舌板部 112的第二舌板部 212及两个配合固定于第 一绝缘件 11的第一固定机构 115的第二固定机构 215。第二舌板部 212具有一向上面对第 一结合面 113的第二结合面 213及一相反于第二结合面 213的第二对接面 214。 第二端子 22的前端由第二基部 211向前延伸以形成一外露于第二对接面 214的第二对接部 221， 而 后端由第二基部 211向外伸出以形成一用以焊接于一电路板 8的第二焊接部 222(见图 7及 图 8)。
接合本体 100还包括两个分别设于第一基部 11 1与第二基部 211后侧的固定脚 101、 两 个分别形成于接合本体 100左右两侧而邻近第一舌板部 1 12与第二舌板部 212后段的收容 槽 102及四个分别形成于第一基部 1 11顶面与第二基部 211底面的凹槽 104。两固定脚 101 分别由第一绝缘件 1 1与第二绝缘件 21后侧向后远离第一绝缘件 11与第二绝缘件 21延伸 而出并穿设固定于电路板 8(见图 7及图 8)。
接地金属片 3夹设于第一端子模块 1 与第二端子模块 2之间， 借此使第一舌板部 1 12 与第二舌板部 212拼接成的舌板结构强度得以提升， 并减少第一端子 12与第二端子 22之 间的高频信号串扰。接地金属片 3的两相反表面分别与该第一舌板部 1 12的第一结合面 113 及第二舌板部 212的第二结合面 213相贴接， 接地金属片 3设有两个分别由左右两侧外露 于第一舌板部 1 12与第二舌板部 212的对接侧缘 31及四个上下贯穿接地金属片 3的通孔 32。 通孔 32对应于第一绝缘件 1 1的第一固定机构 1 15与第二绝缘件 21的第二固定机构 215， 使第一固定机构 1 15穿过接地金属片 3的通孔 32与第二固定机构 215固定接合并同 时将接地金属片 3定位。 在第一较佳实施例中， 第一固定机构 115与第二固定机构 215具 体为对应配合的固定凸柱 1 16、 216与固定孔 1 17、 217。
外屏蔽壳体 4包围接合本体 100的第一舌板部 1 12与第二舌板部 212的外部空间，并形 成一可供对接连接器 7插接的对接腔 41。内屏蔽壳体 5位于该外屏蔽壳体 4与第一基部 1 1 1 及第二基部 21 1之间， 并至少覆盖于该第一舌板部 1 12与该第二舌板部 212的后段， 较佳 地， 该内屏蔽壳体 5还进一步覆盖第一基部 1 1 1或第二基部 21 1朝向对接腔 41的前表面。 内屏蔽壳体 5较佳形成一固定于第一基部 111或第二基部 211前段并抵靠于外屏蔽壳体 4 内表面的固定段 51及一贴合环绕于第一舌板部 1 12与第二舌板部 212后段的延伸段 52， 借此遮蔽电磁波穿过接合本体 100向后泄漏。 具体而言， 在本实施例中内屏蔽壳体 5具有 两彼此拼接的金属板 53。 两金属板 53分别位于接合本体 100的上下两侧以分别固定贴合 第一绝缘件 11与第二绝缘件 21。
每一金属板 53大致呈台阶状， 并具有一水平贴合于对应的第一舌板部 112或第二舌板 部 212后段的前延伸板 531、 一水平贴合于对应的第一基部 111或第二基部 211前段的后 延伸板 534、 一连接前延伸板 531与后延伸板 534并呈垂直延伸的连接板 535、 两个设于 对应的前延伸板 531左右两侧的固定凸片 536及两个向远离接合本体 100方向延伸的连接 弹片 537。 每一前延伸板 531 的前端形成一引导前缘 532， 各引导前缘 532分别与接合本 体 100间形成一缝隙 533(见图 7及图 8)， 使引导前缘 532在对接连接器 7插入对接腔 41 时可微量地向接合本体 100位移而有利于对接连接器 7插入。 接合本体 100左右两侧的收 容槽 102分别邻近各前延伸板 531的左右两侧，且后侧具有一上下延伸并贯穿第一基部 1 11 与第二基部 211的槽道 103。 每一固定凸片 536由对应的前延伸板 531伸入邻近的收容槽 102, 并卡固于对应的槽道 103内与接合本体 100相互固定。 各连接弹片 537分别对应容 置于各凹槽 104内， 且末端弹性接合于外屏蔽壳体 4以使内屏蔽壳体 5通过外屏蔽壳体 4 达成接地的效果。
本发明电连接器 300在与对接连接器 7组合时，各个屏蔽结构能产生多个接地通道以提 升电磁屏蔽效果。 更明确地说， 接地金属片 3除了通过与后侧的电路板 8连接而形成一接 地通道外，还能通过左右两侧外露的对接侧缘 31与对接连接器 7外壳的金属弹臂 (图未示) 连接， 借此形成另一接地通道以为对接连接器 7提供接地功能。 另外， 内屏蔽壳体 5利用 多个连接弹片 537与外屏蔽壳体 4连接以形成一接地通道， 并在对接连接器 7插入时与对 接连接器 7中的接地弹片 71 (见图 9)连接而形成另一接地通道， 让内屏蔽壳体 5及外屏蔽 壳体 4的电磁屏蔽效果都进一步得到提升。
要特别强调地，由于本第一较佳实施例中第一端子模块 1与第二端子模块 2的结构完全 相同， 因此不需要分别开模制作多种不同的组装结构， 只需制造一种型态的端子模块即可 进行组装并夹设固定接地金属片 3 , 使制程与整体结构的复杂度皆大幅简化。 此外， 第一 端子 12与第二端子 22能先分别埋设于第一绝缘件 1 1与第二绝缘件 21的一侧面后再进行 后续组装， 降低了组装制程的难度与设备的复杂度。 并且由于第一端子模块 1中的第一端 子 12与第二端子模块 2中的第二端子 22配置完全相同而彼此呈 180度旋转对称， 所以对 应的对接连接器 7无论是正向或反向地插入电连接器， 皆可与电连接器的端子达成正确的 连接。
综上所述， 通过第一端子模块 1与第二端子模块 2的设计， 使第一端子 12与第二端子 22能分别埋设于第一绝缘件 11与第二绝缘件 21的一侧面后，再将第一端子模块 1与第二 端子模块 2结合并将接地金属片 3夹设在其中， 从而降低了组装程序的难度与设备的复杂 度。另外，借由装设在第一端子 12与第二端子 22之间的接地金属片 3装设在接合本体 100 后部的内屏蔽壳体 5及包围该第一舌板部 112与该第二舌板部 212的外屏蔽壳体 4， 使电 连接器 300的电磁屏蔽结构形成多个接地通道及一个整体的屏蔽结构， 产生更良好的电磁 屏蔽效果。 故确实能达到本发明的目的。
参阅图 10至图 24， 为本发明的电连接器的第二优选实施例。 该电连接器 300c为一直 角型连接器。
参阅图 10与图 1 1， 该电连接器 300c可设置于一电路板 8c以供一对接连接器 7c对接。 参阅图 11至图 17， 该电连接器 300c包含一绝缘本体 10c、 多个端子 20c、 一外屏蔽壳 体 4c、 一内屏蔽壳体 5c、 一接地金属片 3c及一焊脚定位件 6c。
该绝缘本体 10c由一第一绝缘件 11c及一第二绝缘件 21 c组合形成，具有一主体 13c及 一由该主体 13c向前凸伸的舌板 14c。 该主体 13c具有较为宽广的一上表面 131 c、 一下表 面 132c、 连接该上、 下表面 131 c、 132c的两侧面 133c以及一前表面 134c。 该舌板 14c具 有一连接该主体 13c的基部 141 c以及一由该基部 141c向前延伸出的延伸部 142c。 其中该 舌板 14c的基部 141 c的厚度厚于该舌板 14c的延伸部 142c的厚度。 具体到本实施例的该 第一绝缘件 1 1 c包括一第一基部 111 c及由该第一基部 1 11 c向前延伸出的第一舌板部 112c ; 该第二绝缘件 21 c包括一第二基部 21 cl 及由该第二基部 21 1 c 向前延伸出的第二舌板部 212c;该第一舌板部 112c与第二舌板部 212c组合成该绝缘本体 10c的舌板 14c，该第一基 部 1 11 c与第二基部 21 1 c组合成该绝缘本体 10c的主体 13c。
另配合参阅图 18与图 19， 多个端子 20c固设于该绝缘本体 10c且分别具有一露出于该 舌板 14c的延伸部 142c的接触部 201 c， 及一向后伸出该绝缘本体 10c的主体 13c的尾部 202c 0 上排端子 20c的接触部 201c露出于该舌板 14c的延伸部 142c的上表面 143c， 而下 排端子 20c的接触部 201c露出于该舌板 14c的延伸部 142c的下表面 144c。 详细来说， 多 个端子 20c分为上、 下两排， 多个上排端子 20c埋设于该第一绝缘件 l l c， 多个下排端子 20c埋设于该第二绝缘件 21 c。 其中多个上排端子 20c的接触部 201 c是暴露设置在第一舌 板部 112c， 而其尾部 202c是向后伸出第一基部 111 c; 多个下排端子 20c的接触部 201 c是 暴露设置在第二舌板部 212c， 而其尾部 202c是向后伸出第二基部 211c。 每排端子 20c包 括四根向前凸出的端子 20c与八根位置稍后的端子 20c， 其中两侧的两根较长的端子 20c 用于接地， 而中部的两根较长的端子 20c用于提供电源。 八根较短的端子 20c中包括两个 高速差分信号对、位于中央的一个低速差分信号对以及两根控制用端子。其中上排端子 20c 的接触部 201 c与下排端子 20c的接触部 201c相对舌板 14c呈 180度对称设置， 从而使对 接连接器 7c可以 180度翻转地插入到电连接器 300c。
值得一提的是，该绝缘本体 10c与端子 20c的组合相当于前述第一优选实施例中的接合 本体 100。 上排端子 20c与该第一绝缘件 11 c的结合体相当于前述第一优选实施例中的第 一端子模块 1 ; 下排端子 20c与该第二绝缘件 21c的结合体相当于前述第一优选实施例中 的第二端子模块 2。
该外屏蔽壳体 4c与该绝缘本体 10c相结合并围绕该舌板 14c的外部空间界定出一个对 接腔 41 c， 且具有四个焊接脚 42c以固定至电路板 8c。 其中该绝缘本体 10c的前表面 134c 朝向对接腔 41 c。
该内屏蔽壳体 5c覆盖该舌板 14c的基部 141c及该主体 13c的上、 下表面 131c、 132c 与前表面 134c， 且具有多个用以定位该内屏蔽壳体 5c的固定凸片 536c、 538c。 具体而言， 该内屏蔽壳体 5c包括一第一金属板 54c及一第二金属板 55c。 该第一金属板 54c具有一覆 盖该基部 141c的前延伸板 531 c、 从该前延伸板 531 c的后端垂直弯折延伸出的一连接板 535c, 以及从该连接板 535c的上缘水平向后延伸出的一后延伸板 534c。该第二金属板 55c 具有一覆盖该基部 141 c的前伸延板 531 c、 从该前伸延板 531 c的后端垂直弯折延伸出的一 连接板 535c， 以及从该连接板 535c下缘水平向后延伸出的一后延伸板 534c。 这两个前伸 延板 531 c覆盖该舌板 14c的基部 141 c的上下两侧， 这两个连接板 535c覆盖于该主体 13c 的前表面 134c, 这两个后延伸板 534c分别覆盖于该主体 13c的上、 下表面 131 c、 132c。 换言之，该第一金属板 54c及该第二金属板 55c共同覆盖该舌板 14c的基部 141 c的上下两 侧， 亦即该内屏蔽壳体 5c覆盖该舌板 14c的基部 141c， 以将多个端子 20c环绕包围在其 中且与这些端子 20c保持有一间隙。在某些较为精简的替代实施例中（图未示）， 该内屏蔽 壳体 5c也可以被设置为仅仅覆盖该舌板 14c的基部 141 c， 或是只覆盖该舌板 14c的基部 141 c与该主体 13c的前表面 134c， 从而在一定程度上达到接地屏蔽的效果， 防止对接腔 41c内的电磁辐射穿过绝缘本体 10c向后泄漏影响端子 20c的尾部，从而达到提高端子 20c 的信号传输质量以及防止电磁辐射泄漏到电连接器 300c外部的目的。
该绝缘本体 10c还具有两个靠近该舌板 14c的基部 141c两侧且沿上下方向延伸的槽道 135c、多个分别形成于该上、下表面 13】c、 132c的卡槽 136c，及两个形成于该上表面 131 c 的让位凹槽 137c。 在某些替代实施例中的两槽道的后端终止于主体 13c的前方或主体 13c 与舌板 14c的交接处（图未示）， 其中四个固定凸片 536c分别形成于这两个前延伸板 531 c 的横向两侧并嵌入卡置于对应的槽道 135c， 从而达到固定这两个前延伸板 531 c的目的。 而具体到本较佳实施例的两槽道 135c还较佳是进一步向后延伸到该绝缘本体 10c的主体 13c内一设定深度， 并上下贯穿该主体 13c; 四个固定凸片 536c的后部嵌入至该主体 13c 上形成的槽道内 135c， 从而被该主体 13c夹持固定在其中， 借此防止固定凸片 536c向外 张开发生变形； 四个固定凸片 538c较佳是分别形成于这两个后延伸板 534c的横向两侧以 嵌入卡置于对应的卡槽 136c， 用以加强固定第一金属板 54c及第二金属板 55c; 另外两个 焊接脚 59c形成于该第二金属板 55c的连接板 535c及该后延伸板 534c，焊接脚 59c由该前 伸延板 531c朝向该外屏蔽壳体 4c延伸出，该外屏蔽壳体 4c具有对应的两个穿孔 43c以容 置对应的焊接脚 59c， 使位于对应穿孔 43c的悍接脚 59c可焊接于电路板 8(见图 20、 21 ) 形成接地及提供固定的效果。该第一金属板 54c还具有形成于该连接板 535c及该后延伸板 534c的两个连接弹片 537c，两个连接弹片 537c由该前延伸板 531c延伸出并与该外屏蔽壳 体 4c接触 (见图 21)，从而使该内屏蔽壳体 5c与该外屏蔽壳体 4c达成接地及辅助固定的效 果。
该内屏蔽壳体 5c的前缘较佳具有呈弯弧状的至少一导引部， 该舌板 14c还对应该导引 部形成有至少一让位沟槽， 其中该导引部的前端缘与让位沟槽之间具有一间隙， 从而可供 导引部微量活动于其中。 具体到本较佳实施例， 该第一金属板 54c还具有一形成于该前延 伸板 531 c前缘且呈弯弧状的导引前缘 532c， 该第二金属板 55c还具有一形成于该前伸延 板 531 c前缘且呈弯弧状的导引前缘 532c。 该舌板 14c还具有两个分别形成于该基部 141 c 上、 下表面 143c、 144c的让位沟槽 145c (见图 21)， 以分别容置这两个导引前缘 532c。 当 对接连接器 7c (见图 10)与电连接器 300c对接过程中， 这两个导引前缘 532c可使对接连接 器 7c的对接前缘 73c容易通过而不会产生阻滞。 而且， 当对接连接器 7c与电连接器 300c 对接后， 对接连接器 7c的多个上、 下接地弹片 71 c可以接触该内屏蔽壳体 5c的两个前延 伸板 531对接以达成接地的效果， 从而构成第一接地屏蔽结构来阻止电磁辐射穿过绝缘本 体 10c向后泄露。 而该外屏蔽壳体 4c与该对接连接器 7c的屏蔽外壳 72c接触， 构成第二 接地屏蔽结构， 从而可以有效地在对接腔 41 c的外周达成一个整体包围的屏蔽效果。
参阅图 16至图 19， 该接地金属片 3c夹设于该第一绝缘件 11c与该第二绝缘件 21 c之 间。 该接地金属片 3c为介于上、 下排端子 20c之间的板体， 包括一第一遮蔽部 33c及由该 第一遮蔽部 33c延伸的一第二遮蔽部 35c， 及两个分别由该第一遮蔽部 33c向后延伸出该 绝缘本体 10c且位于该第二遮蔽部 35c两侧的接地脚 36c。 其中第一遮蔽部 33c固设于该 绝缘本体 10c内， 该第二遮蔽部 35c与端子 20c的尾部 202c同方向伸出该绝缘本体 10c; 具体而言，该第二遮蔽部 35c由该接地金属片 3c的第一遮蔽部 33c后端垂直向下弯折而成， 并在多个上排端子 20c的尾部 202c与多个下排端子 20c的尾部 202c之间沿横向延伸。 在 本实施例中， 该第二绝缘件 21 c具有多个固定凸柱 116c， 且该第一绝缘件 1 1c上具有多个 分别与多个固定凸柱 1 16c相配合卡接的固定孔 1 17c， 该接地金属片 3c具有多个形成于该 第一遮蔽部 33c以分别供对应固定凸柱 1 16c穿设的通孔 32c。当然，在等效的实施方式中， 也可以是该第一绝缘件 11 c具有固定凸柱， 而该第二绝缘件 21c具有固定孔。 该接地金属 片 3c可以增强舌板 14c的强度并减少上排端子 20c与下排端子 20c传输信号时的高频串扰， 尤其第二遮蔽部 35c在多个上排端子 20c的尾部 202c与多个下排端子 20c的尾部 202c之 间沿横向延伸，更进一步加强屏蔽的效果，并通过接地脚 36c接地，从而达到提高端子 20c 的电性能的目的。 再者， 参阅图 10与图 12， 该舌板 14c还具有两个分别由该延伸部 142c 两侧相向凹入的扣持部 146c， 且该接地金属片 3c的部分侧缘露出于这些扣持部 146c， 借 此， 对接连接器 7c与电连接器 300c对接时， 对接连接器 7c的扣持弹片 (未图示)可以扣持 在对应的扣持部 146c并与接地金属片 3c接触， 且通过接地金属片 3c的接地脚 36c接地， 从而使对接连接器 7c具有较佳的接地效果。
参阅图 18至图 21， 该焊脚定位件 6c与该绝缘本体 10c的本体 13c结合固定。 具体而 言， 该焊脚定位件 6c结合于该第二绝缘件 21 c后侧且在该第一绝缘件 11 c下方， 并具有分 别凸出左右两侧的两个卡块 61 c以卡置于该第二绝缘件 21 c上的限位槽 118c， 及多个上下 贯穿的定位孔 62c、63c以分别供多个端子 20c的尾部 202c及该接地金属片 3c的接地脚 36c 穿设定位， 从而防止多个尾部 202c及接地脚 36c变形。 在本实施例中， 多个下排端子 20c 的尾部 202c笔直向下延伸为穿孔焊接形式的焊脚。 多个上排端子 20c的尾部 202c末端形 成弯折， 为表面悍接形式的焊脚， 且位于多个下排端子 20c的尾部 202c后方， 该焊脚定位 件 6c中位于后排的定位孔 63c还贯穿后侧面以穿设多个上排端子 20c的尾部 202c。 此夕卜， 该焊脚定位件 6c还具有一定位凹槽 64c以对应容置该接地金属片 3c的第二遮蔽部 35c的 末端 (见图 22), 其中该定位凹槽 64c位于对应收容上排端子 20c的定位孔 63c与对应收容 下排端子 20c的定位孔 62c之间。
参阅图 19、 图 22至图 24， 该第一绝缘件 11c较该第二绝缘件 21 c向后凸伸， 并于凸伸 部分的底面向下凸出形成一端子间隔部 15c。该接地金属片 3c的后部形成有一供该端子间 隔部 15c穿过的穿孔 34c。参阅图 22至图 24， 该端子间隔部 15c压抵于位于中间的两根下 排端子 20c较向后凸出的尾部 202c， 以避免多个端子 20c的尾部 202c在安装到电路板 8c 时向上弯折变形与该接地金属片 3c接触导致短路。
综上所述， 本发明电连接器 300c借由接地金属片 3c增强舌板 14c的强度并减少端子 20c传输信号时的高频串扰， 且由于第二遮蔽部 35c在多个上排端子 20c的尾部 202c与多 个下排端子 20c的尾部 202c之间沿横向延伸， 更进一步加强屏蔽的效果，从而达到提高电 性能的目的且更增加接地屏蔽效果。 此外， 该绝缘本体 10c由第一绝缘件 1 1 c及第二绝缘 件 21 c组合形成， 再组合该焊脚定位件 6c供多个端子 20c的尾部 202c及该接地金属片 3c 的接地脚 36c穿设定位，如此绝缘部件采用三件式的组合，有利于电连接器 300c的微型化 且能使制造及组装较为容易。
然而以上所述，仅为本发明的较佳实施例而已， 当不能以此限定本发明， 即凡依本发明 权利要求书及专利说明书内容所作的简单的等效变化与修饰， 皆仍属本发明的权利要求的 范围内
