本发明涉及电连接器领域，特别是涉及一种USB插座及其制造方法。
背景技术
传统USB接口需要按规定方向插接，例如Micro USB接口，其对应的插头与插座需要按既定的对接方向对接，且结构尺寸非常小，塑胶结构强度不足，用户在插接时，容易插座方向，即使有防误插设计，但部分用户大力地错误插入，仍会造成电子设备内的插座端产生不可逆的损坏，比如，对接舌板损坏而整体移位，造成对接舌部无法插入插头的腔体内实现对接，甚至多次错误插拔造成舌板损伤后会造成舌板上的插座端子断裂而完全失去充电及信号传输功能。Type C型USB插座解决了传统Micro USB接口的问题，实现正反插的兼容，但Type C型连接器为适应电子设备的小型化，尺寸结构仍较小，而内部需要实现的功能更为强大，完整版Type C接口需要在上下两侧设置多达24Pin的独立端子，制造难度较大，且上下两排端子之间间隔有金属中板，造成在制造Type C型插座时，需要较为复杂的工艺，现有工艺一般采用三次注塑成型工艺，例如，先将金属中板与其中一排端子组注塑成型为一体、将另一排端子组注塑成型为一体，再将二者叠合呈一体再次注塑成型结合为一体；最后，为裁切端子组前端的料带，需要再次注塑成型来包裹端缘部。如此多的注塑成型工艺，造成产品制造成本居高不下，难以适应竞争激烈的市场。且部分电子设备，例如手机，用户更需要接口的充电能力，而信号传输能力并不被需要。

实施例一
本申请以图1所示X方向为左右方向(横向方向)，以Y方向为前后方向(纵向方向)，以Z方向为垂直方向。
请参阅图1、图2所示，本申请USB插座为Type C型USB插座，支持正反向插拔。本申请USB插座包括插接件A及套设于所述插接件A外的金属壳体10。
所述金属壳体10包括筒体11、通过所述筒体11围设成的腔体12、自所述 筒体11上冲压形成的第一、第二焊接脚16，17。
所述筒体11包括上下两侧的垂直筒壁111及在横向方向上连接所述垂直筒壁111的横向筒壁112。所述垂直筒壁111的后端朝向所述腔体12方向冲压形成有若干前卡块13，位于上侧的所述垂直筒壁111在所述前卡块13后端向下折弯形成有第一后卡块14，所述横向筒壁112后端向内折弯形成有第二后卡块15。所述横向筒壁112靠前侧撕裂折弯形成有第一焊接脚16，所述横向筒壁112后端向下折弯形成有第二焊接脚17。所述第一、第二焊接脚16，17卡入一印刷电路板(未图示)的焊孔内焊接并固定USB插座于所述印刷电路板上。
请继续参阅图2至图8所示，所述插接件A包括端子组30及将所述端子组30固持为一体的绝缘本体20。所述绝缘本体20包括基部21、自所述基部21前向延伸形成的包裹部22、自所述包裹部22前向延伸形成的对接舌部23及自所述基部21后端上侧向后延伸形成的尾部24。所述对接舌部23横向外侧设有对接凸部25及位于所述对接凸部25后方的对接凹部26。
所述基部21的外径大于包裹部22的外径，所述包裹部22的外径大于所述对接舌部23的外径。所述基部21的前端缘开设有若干前卡槽211，所述前卡槽211收容所述金属壳体10的若干所述前卡块13并限制所述插接件A向前移动。所述尾部24后端开设有第一后卡槽241，所述尾部24的横向两侧设有第二后卡槽242。在所述插接件A插入所述腔体12后，所述金属壳体10的第一、第二后卡块14，15被折弯并卡入所述第一、第二后卡槽241，242内并限制所述插接件A向后移动，配合所述前卡块13与所述前卡槽211在插拔方向上限位所述插接件A。
请重点参阅图3至图8所示，所述端子组30包括位于横向最外侧一对接地端子31、位于一对所述接地端子31之间的一对电源端子32及置于一对所述接地端子31上或下侧的金属加强件33。本申请的USB插座仅需要具备充电功能即可，即仅需要设置接地端子31与电源端子32即可；而在其他实施例中，所述接地端子31与所述电源端子32之间还分别设有一对高速信号端子，一对所述电源端子32之间还设有两对常规信号端子，而依据电子设备对电能传输与信 号传输的要求，可以自主设置信号端子，若除电能传输需求外，还需要进行一些低速信号的传输，则可以增加常规信号端子；若对高速信号传输有需求，则可以同时设置所述高速信号端子与常规信号端子。在具体实施中，所述高速信号端子与所述常规信号端子的结构设计与所述电源端子32的结构设计一致。
所述接地端子31与电源端子32均包括嵌入所述绝缘本体20的基部21与包裹部22内的嵌入部311，321、自所述嵌入部311，321后向延伸至所述尾部24底面的焊脚312，322及自所述嵌入部311，321前向延伸形成的暴露于所述对接舌部23一侧表面的第一接触部313，323。
本申请USB插座为沉板式结构，所述焊脚312，322的下表面暴露于所述尾部24的底面上，而所述尾部下方形成有沉板避让部243以搭接于所述印刷电路板上，即所述USB插座的一部分沉入印刷电路板的另一侧，如此，可以降低印刷电路板上的板上厚度。
所述接地端子31的第一接触部313前端缘设有拍薄部314，使所述拍薄部314被所述绝缘本体20的对接舌部23前端缘所包裹以避免所述第一接触部313前端向上开裂。所述金属加强件33与所述接地端子31的第一接触部313背面电性接触并形成露出于所述对接舌部23另一侧表面的第二接触部333。所述金属加强件33采用不锈钢材质制成，所述金属加强件33包括第一板体部331、自所述第一板体部331横向内侧反向折弯形成的与所述第一板体部331层叠设置的第二板体部332、自所述第一板体部331中间远离所述第二板体部332冲压形成的所述第二接触部333、自所述第二板体部332中间远离所述第一板体部331方向冲压形成的搭接部334及形成于所述第二板体部332横向外侧的卡扣槽336。所述第二板体部332的横向宽度大于所述第一板体部331的横向宽度，所述第一、第二板体部331，332上的第二接触部333与搭接部334在垂直方向上的投影至少部分重叠。所述第一板体部331冲压形成所述第二接触部333位置处形成有第一凹槽338，所述第二板体部332冲压形成所述搭接部334位置处形成有第二凹槽339。所述第一凹槽338的横向外侧呈开放状态，所述第一凹槽338与所述第二凹槽339在上下方向上至少部分相互面对。所述第二板体部332的横 向外侧前端向外凸出形成有横向外凸部335，所述卡扣槽336形成于所述外凸部335后侧，所述第二板体部332横向外侧还设有连料部337。所述外凸部335与所述卡扣槽336分别对应露出于所述对接凸部25与所述对接凹部26的外侧面。所述对接凸部25与所述对接凹部26的横向外侧面及与其对应的外凸部335与卡扣槽336的横向外侧面平滑过渡。一对所述金属加强件33通过所述连料部337连接于一个料带上。所述搭接部334与所述接地端子31的接触部313的背面电性接触。所述金属加强件33是通过一片金属板材冲压加工成型的，先预先在所述第一板体部331与第二板体部332上分别冲压形成所述第二接触部333与搭接部334；而后，再翻折所述第一板体部331与第二板体部332使所述第一第一、第二板体部331，332相互层叠，为使所述第一板体部331与所述第二板体部332面对的表面相互贴合，需要在翻折之前，在所述第一板体部331与所述第二板体部332折弯位置处进行预压薄，使折弯位置的内侧变薄或者产生槽结构等，如此在翻折时，内R角处的金属才不会造成挤压增厚而使所述第一板体部331与所述第二板体部332无法贴合。
所述电源端子32还包括自所述第一接触部323的前端反向折弯延伸形成的第二接触部324及形成于所述第一接触部323与所述第二接触部324折弯位置处的折弯部325。所述接地端子31、电源端子32的第一接触部313，323的表面暴露于所述对接舌部23的垂直第一表面上，所述金属加强件33，电源端子32的第二接触部334，324的表面暴露于所述对接舌部23的垂直第二表面上。
所述对接舌部23的上下表面在所述接地端子31、金属加强件33及电源端子32的前端缘位置处向上及向下凸出形成有凸起27，具体地，所述电源端子32位于所述折弯部325上下两侧的第一、第二接触部323，324前端缘处形成与所述对接舌部23一体成型并包裹所述第一、第二接触部323，324前端缘的凸起27；所述接地端子31的第一接触部313与所述金属加强件33的第二接触部334前端缘位置处一体成型包裹所述第一接触部313、第二接触部334前端缘的凸起27。所述凸起27表面与所述第一、第二接触部323，313，324，334暴露的外表面平齐并凸出所述对接舌部23的表面。所述凸起27起到加固所述端子 组30前端缘的作用，同时可以引导对接端子的插入，防止对接端子插入受限而导致损坏。
在其他实施例中，所述常规信号端子与高速信号端子均参考所述电源端子32的结构设计，即在所述第一接触部323前端反向折弯形成暴露于所述对接舌部23另一侧表面的第二接触部324；如此可以减少一排导电端子，同时减少了冲压端子的动作，节省了原材料。在具体实施时，所述接地端子31的横向外侧需要设置与USB插头卡扣的卡扣槽，而卡扣槽需要采用耐磨材料制作，导电端子一般需要采用低阻值的铜材制作，而铜材的耐磨性较差，需要采用不锈钢等材质金属，故不能直接采用接地端子用作卡扣槽的设计。而所述金属加强件33正好叠加固定于所述接地端子31上，作为第二接触部334及卡扣槽336的设计，解决了上述问题。
在注塑成型时，通过将所述金属加强件33与接地端子31上下方向叠加固定，所述电源端子32(及信号端子)与所述接地端子31一体冲压并与所述接地端子31连接于同一个料带上固定，直接一次注塑成型即可，而塑胶材料将所述接地端子31、电源端子32及金属加强件33结合固定在一起，同时，所述电源端子32的第二接触部324后端延伸嵌入所述包裹部22内以防止裂开。所述金属加强件33的第一、第二凹槽338，339内填充满塑胶材料可增加塑胶材料对所述金属加强件33的固持力。所述电源端子32的第一、第二接触部323，324之间被塑胶材料所填充并固定所述第一、第二接触部323，324的相对位置。
实施例二
请继续参阅图9所示，为本申请第二实施例沿接地端子31的剖视图，相较于实施例一，本实施例的所述接地端子31的拍薄部314’朝向所述金属加强件33一侧折弯，所述第二板体部332在横向一侧设有扣合孔4，所述接地端子31的拍薄部314’穿越所述扣合孔4后抵持于所述第二板体部332的前缘5表面上。所述扣合孔4可以从横向内侧或外侧开设，所述接地端子31自所述扣合孔4的横向开口方向卡入。此设计，可以增强所述金属加强件33与所述接地端子31之间的牢固度及提升接触性能。
本申请USB插座的制造方法包括如下步骤：
第一步骤，提供固定于同一料带上的端子组30，所述端子组30至少包括一对电源端子32及最外侧的一对接地端子31，所述一对电源端子32位于一对所述接地端子31之间，所述电源端子32包括嵌入部321、自所述嵌入部321后向延伸形成的焊脚322、自所述嵌入部321前向延伸形成的第一接触部323及自所述第一接触部323前端反向折弯并向后延伸形成的第二接触部324，所述接地端子31包括嵌入部311、自所述嵌入部后向延伸的焊脚312及自所述嵌入部311前向延伸形成的第一接触部313，所述第一接触部313的前端缘设有拍薄部314，所述端子组30的料带分别与所述电源端子32及接地端子31的焊脚322，312相连；
第二步骤，提供固定于另一料带的一对金属加强件33，所述金属加强件33包括第一板体部331及自所述第一板体部331横向内侧翻折形成的与所述第一板体部331贴合的第二板体部332，所述第一板体部331朝向垂直第一方向冲压凸出形成所述金属加强件33的第二接触部333，所述第二板体部332横向外侧还设有连料部337，所述另一料带分别连接于一对所述金属加强件33横向外侧的连料部337上；
第三步骤，令所述端子组30与所述金属加强件33层叠固定，令所述第二板体部332的上表面向上抵持于所述接地端子31的第一接触部313的背面；
第四步骤，提供一绝缘本体20，所述绝缘本体20包括基部21、自所述基部前向延伸形成的包裹部22及自所述包裹部前向延伸形成的对接舌部23，令所述绝缘本体20与所述端子组30和一对金属加强件33一次注塑成型为一体，令所述电源端子32和接地端子31的第一接触部312的表面暴露于所述对接舌部23的垂直第一侧面外，令所述电源端子32和金属加强件33的第二接触部324，333的表面暴露于所述对接舌部23的垂直第二侧面外；
第五步骤，断开所述电源端子32和接地端子31与料带之间的连接，断开所述金属加强件33与另一料带之间的连接。
本申请通过将电源端子32的第一接触部323前端反向折弯延伸形成暴露于 所述对接舌部23另一侧表面的第二接触部324，减少了一组导电端子的设计，并可实现一次注塑成型，降低了制造成本；同时，采用金属加强件33在垂直两侧分别冲压形成与所述接地端子31的第一接触部313电接触的搭接部334及暴露于所述对接舌部23另一侧表面的第二接触部333，且所述金属加强件33横向外侧设置与USB插头卡持摩擦的卡槽，既保证了正反插的功能，又保证了卡扣槽336的耐磨性。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本发明的优选的实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
