具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图说明本发明 的具体实施方式。在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
方案一
本发明提供了一种电连接器，如图1-图24所示，该电连接器包括：护套10、屏蔽壳体20、内绝缘体30和至少一个内导体端子40，屏蔽壳体20包括屏蔽筒21和第一凸肋221，第一凸肋221与屏蔽筒21分体成型并且第一凸肋221固接于屏蔽筒21外；内绝缘体30设置于屏蔽筒21内，内导体端子40设置于内绝缘体30内；护套10的内壁设置有第一止位台阶13，屏蔽壳体20安装于护套10内，并且第一凸肋221抵接于第一止位台阶13。
屏蔽壳体20中的屏蔽筒21采用金属制作，第一凸肋221可以采用非金属材料制作，从而减轻了屏蔽壳体20的重量，降低了材料成本和制造成本。屏蔽筒21实现了屏蔽功能，同时，护套10与屏蔽壳体20之间通过第一凸肋221来定位，保障了装配定位的准确性和结构的稳定性，该电连接器的整体重量大大减轻，有利于推广应用。
在一实施方式中，屏蔽壳体20包括第二凸肋222，第二凸肋222与屏蔽筒21分体成型并且第二凸肋222固接于屏蔽筒21外，第二凸肋222位于第一凸肋221的前方，并且，第二凸肋222与第一凸肋221之间设置有定位槽23；该电连接器包括锁位体50，护套10的侧壁设置有锁位槽11，锁位体50插设于定位槽23和锁位槽11中。屏蔽壳体20可以从护套10的后端装入到护套10内，通过第一凸肋221来阻止屏蔽壳体20相对于护套10向前运动，保障屏蔽壳体20在护套10中组装到位；通过锁位体50来阻止屏蔽壳体20相对于护套10向后运动，从而对屏蔽壳体20在护套10内的纵向位置进行定位，方便组装，提高了装配定位的准确性。
进一步地，如图14-图16所示，锁位体50包括两个对称布置的锁位悬臂51；锁位槽11的内壁设置有锁位凸起块，锁位悬臂51的外侧设置有锁位凹槽52，沿图15中的从上往下的方向将锁位体50插入到锁位槽11中，锁位凸起部卡入到锁位凹槽52中，实现锁位体50与护套10之间的扣合固定，锁位悬臂51的前侧与第二凸肋222抵接，以进行纵向止退限位。
第一凸肋221在屏蔽筒21上的固接方式可以有多种，例如卡接或螺接。第二凸肋222也可以采用任一可行的方式实现与屏蔽筒21固接。在一实施方式中，第一凸肋221和第二凸肋222均注塑成型于屏蔽筒21外。进一步地，如图11-图13所示，屏蔽筒21的外壁设置有多个冲压成型的第一凸起部241，第一凸起部241分别嵌入第一凸肋221 和第二凸肋222中，有利于提高第一凸肋221与屏蔽筒21之间的牢固度、和第二凸肋222与屏蔽筒21之间的牢固度。
屏蔽筒21可以采用冲压工艺，冲压时，在屏蔽筒21的圆周区域，加工出向外凸起的第一凸起部241，再由一体注塑成型工艺，注塑出第一凸肋221和第二凸肋222，注塑成型时，第一凸起部241可以刺入第一凸肋221和第二凸肋222内，从而提供第一凸肋221和第二凸肋222与屏蔽筒21间的保持力。第一凸肋221和第二凸肋222可以采用树脂材料，减低了屏蔽壳体20的整体的重量和生产成本。屏蔽筒21为金属件，具有比较好的塑性，第一凸起部241可以通过冲压成型，可以为凸包，也可以为预刺破结构。
在一实施方式中，内绝缘体30设置有端子孔31，内导体端子40插设于端子孔31中；电连接器还包括挡板60，挡板60安装于内绝缘体30，并且挡板60的前侧与内导体端子40抵接，如图8所示，内导体端子40可以沿从后向前的方向装入到端子孔31中，装入到位后，内导体端子40与端子孔31的台阶部抵接并被限制继续向前运动；然后，将挡板60安装到内绝缘体30上，通过挡板60，内导体端子40被限制相对于内绝缘体30向后运动，从而实现内导体端子40与内绝缘体30之间纵向定位，并且便于两者的组装。内绝缘体与内导体端子通过挡板来进行限位，方便组装，能够更好地保障装配质量，降低生产成本。具体地，内导体端子40的具有变径特征，通过与台阶部抵接，形成前止位；内导体端子40通过与挡板60配合，形成后止位。
进一步地，如图18-图19所示，内绝缘体30的侧壁设置有安装槽32，挡板60安装于安装槽32，挡板60与内绝缘体30包覆内导体端子40。挡板60上设置有卡块61，内绝缘体30上设有相配合的卡槽，挡板60与内绝缘体30形成扣合，并且卡块61卡接到卡槽中，内导体端子40与挡板60形成后止位。
内绝缘体30、内导体端子40与挡板60组装完成后，作为整体一起装入屏蔽壳体20中。在一实施例中，屏蔽筒21的外壁设置有冲压成型的第二凸起部242，第二凸起部242的前侧抵接于挡板60，形成后止位结构。进一步地，屏蔽筒21的外壁设置有冲压成型的第三凸起部243，第三凸起部243的后侧抵接于内绝缘体30，形成前止位结构。第二凸起部242和第三凸起部243可以通过冲压成型，可以为凸包，也可以为预刺破结构。优选地，如图9所示，第二凸起部242和第三凸起部243均均为预刺破结构。
如图4和图7所示，内绝缘体30的端部设置有导向板301，导向板301起到导向作用，便于该电连接器与配对的连接装置插接时，内绝缘体30和内导体端子40分别进行对接。
在一实施方式中，该电连接器包括后盖70，后盖70设置有用于固持线束81的后盖通孔71，后盖70安装于护套10的后端。通过后盖70与护套10固定，后盖70与线束81固持，将线束81径向的力通过后盖70传递到护套10上，从而保护线束81，避免线束81脱出。
如图1、图2和图7-图9所示，后盖70设置有弹性臂和裙边结构732，裙边结构732起到组装止位的作用，弹性臂上设有凸起结构731；护套10上设有后盖锁定孔12。预先向后盖70穿入线束81，在屏蔽壳体20与固持的线束81组装到位后，将后盖70扣合到护套10上，使后盖70的裙边结构732与护套10端面贴合，达到组装位，使凸起结构731扣合到后盖锁定孔12，形成安全可靠的径向固持保护。优选地，凸起结构731与裙边结构732均呈圆周对称，故而在组装时径向无方向性，方便组装，并且，公端的电连接器和母端的电连接器所使用的后盖70的结构相同，可以减少零件数量，方便生产，有利于降低生产成本。
如图9-图12所示，屏蔽壳体20包括设置于屏蔽筒21的后端的线束压接部211，线束81插入到位后，通过压接工装使线束压接部211收缩卷曲，形成圆环，从而与线束81固持在一起。
进一步地，后盖70包括保护筒72，线束压接部211至少部分设置于保护筒72中，保护筒72能够对线束压接部211提供安全可靠的径向固持保护功能。后盖70可以采用绝缘塑胶材料，保护筒72在提供径向固持的同时包裹线束压接部211，避免屏蔽壳体20的金属外露，对线束81与屏蔽壳体20的连接处进行保护，避免触电的风险，提高了安全性。
在一实施例中，该电连接器还包括线束81。
该电连接器可以为插头或插座，即该电连接器既可以用作公端，也可以用作母端。该电连接器还可以用作其它电连接装置。该电连接器可以为HSD连接器，具有安全可靠轻量化的优点。锁位体50、挡板60和后盖70，能够实现公母端通用。
