相关申请
本申请要求专利申请号为202222929137.8、申请日为2022年11月03日、发明名称为“一种连接器的外导体组件”的中国实用新型专利的优先权。
技术领域
本发明涉及连接器技术领域，尤其是一种连接器的外导体组件及连接器。
背景技术
在当今的电子通讯领域，如语音传输、数据传输以及图像传输等场合，均需要用到同轴高速线缆传输数据，同轴高速线缆的两端设置同轴连接器。同轴连接器可用于连接电路板与电路板、电路板与模块以及模块与模块之间的互联。
目前，同轴连接器中外导体组件一般使用机械加工或压铸的方式生产，加工成本高，浪费工时，越来越多的外导体组件采用金属板材冲压加工成型。但是为了将外导体组件内外分别与内绝缘体和外壳体固定连接，金属板材加工的外导体组件表面都会冲压出连接片，从而导致筒状的外导体组件表面不是完全封闭，在同轴连接器传输频率越来越高的情况下，同轴连接器外导体组件的屏蔽效能无法达到要求，导致数据传输失效。同时由于连接片本身强度低，外力作用时易变形，可靠性较低，严重时会导致外导体组件从外壳体中脱离，造成同轴高速线缆功能丧失，因此设计一种高封闭性，固定位置强度高的外导体组件很有必要。
发明内容
本发明要解决现有技术中的加工成本高，浪费工时，可靠性较低的技术问题，提供一种连接器的外导体组件及连接器。
为了解决上述技术问题，本发明的技术方案具体如下：
本发明提供一种连接器的外导体组件，包括筒状的外导体和套设在所述外导体内部的绝缘体；
所述外导体内设有依次连接的第一腔体、第二腔体和第三腔体，所述第二腔体的径 向尺寸不同于所述第一腔体和第三腔体的径向尺寸，所述第一腔体和所述第二腔体的内壁之间通过第一台阶面连接，所述第二腔体和所述第三腔体的内壁之间通过第二台阶面连接；
所述绝缘体外周设置环形凸起或环形凹槽，至少部分所述环形凸起或所述环形凹槽的轴向两个环形端面分别与所述第一台阶面和所述第二台阶面抵接，以实现所述绝缘体在所述外导体内的轴向定位。
本发明提供一种连接器，包括内导体、护套和上述的外导体组件，所述外导体组件设置在所述护套中，所述内导体卡接在所述绝缘体内。
本发明具有以下的有益效果：
1、外导体一体冲压成型后再将绝缘体包裹其中，简化了绝缘体安装到外导体中的加工步骤，提高加工效率。另外不同直径的腔体对绝缘体进行限位，从而使绝缘体固定在外导体中，定位准确，同轴度高且绝缘体不易松动或移动。
2、外导体通过不同直接的台阶面与外壳体内壁连接，使外导体不需要对侧壁进行冲压形成连接片，筒状的外导体表面完全封闭，屏蔽效能明显提高，从而保证了数据传输的精准度。
3、绝缘体的设置方式可以采用组装或一体注塑，能够一次性加工成型，避免了人工组装的过程，自动化程度高，极大的提高了生产效率。
4、外导体中不同的腔体之间设置斜面连接，既能降低不同腔体连接处的加工应力，提高变径处的机械强度，延长外导体的使用寿命；斜面和倒角的配合又能对绝缘体在外导体中的轴向和径向位移同时限制，避免因为加工误差导致绝缘体在外导体中的微小位移，保证绝缘体和外导体的同轴度，从而保证了数据传输的精准度。

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。
请参阅图1-6，一种连接器的外导体组件，包括筒状的外导体1和套设在外导体1内部的绝缘体2；
外导体1内设有依次连接的第一腔体101、第二腔体102和第三腔体103，第二腔体102的径向尺寸不同于第一腔体101和第三腔体103的径向尺寸，第一腔体101和第二腔体102的内壁之间通过第一台阶面3连接，第二腔体102和第三腔体103的内壁之间通过第二台阶面4连接；
绝缘体2外周设置环形凸起201或环形凹槽202，至少部分环形凸起201或环形凹槽202的轴向两个环形端面分别与第一台阶面3和第二台阶面4抵接，以实现绝缘体2在外导体1内的轴向定位。
目前的同轴连接器中，越来越多的外导体组件采用金属板材冲压加工成型。但是为了将外导体组件内外分别与内绝缘体和外壳体固定连接，金属板材加工的外导体组件表面都会冲压出连接片，从而导致筒状的外导体组件表面不是完全封闭，在同轴连接器传输频率越来越高的情况下，同轴连接器外导体组件的屏蔽效能无法达到要求，导致数据传输失效。同时由于连接片本身强度低，外力作用时易变形，可靠性较低，严重时会导致外导体组件从外壳体中脱离，造成同轴高速线缆功能丧失。
本文中的外导体组件，通过设置外导体1的第一腔体101、第二腔体102和第三腔体103径向尺寸不同，从而将绝缘体2固定设置在第二腔体102中，不需要在外导体1的侧面冲压与绝缘体2和护套6连接的连接片，外导体1采用金属板材冲压加工成型，再将绝缘体2包裹其中，筒状的外导体1表面完全封闭，屏蔽效能明显提高，从而保证了数据传输的精准度。
绝缘体2安装在外导体1的内部，绝缘体2的环形凹槽202或者环形凸起201的两个端面分别与第一台阶面3和第二台阶面4抵接，使绝缘体2无法在外导体1内轴向运动，但不妨碍径向转动。
外导体1通过不同直接的台阶面与外壳体内壁连接，使外导体1不需要对侧壁进行冲压形成连接片，筒状的外导体表面完全封闭，屏蔽效能明显提高，从而保证了数据传 输的精准度。
外导体一体冲压成型后再将绝缘体包裹其中，简化了绝缘体安装到外导体中的加工步骤，提高加工效率。另外不同直径的腔体对绝缘体进行限位，从而使绝缘体固定在外导体中，定位准确，同轴度高且绝缘体不易松动或移动。
在一种实施方式中，如图2、4和5所示，绝缘体2至少部分设置在第一腔体101内和/或第三腔体103内。
绝缘体2安装在外导体1内的第二腔体102中，包裹内导体7的长端插入到第一腔体101内，尾端可以安装在第三腔体103，便于接线，或者不安装在第三腔体103内，便于第三腔体103内压接导线，具体情况需要配合连接器的生产而定，以上两种情况均可使外导体1正常工作。
在一种实施方式中，如图1和2所示，环形凸起201或环形凹槽202的端面设置倒角5，第一台阶面3和第二台阶面4设置为与倒角5的角度一致的斜面。
外导体1中不同的腔体之间设置斜面连接，既能降低不同腔体连接处的加工应力，提高变径处的机械强度，延长外导体1的使用寿命；斜面和倒角5的配合又能对绝缘体2在外导体1中的轴向和径向位移同时限制，避免因为加工误差导致绝缘体2在外导体1中的微小位移，保证绝缘体2和外导体1的同轴度，从而保证了数据传输的精准度。
在一种实施方式中，如图4和5所示，环形凸起201或环形凹槽202的至少部分外周面与第二腔体102的内壁抵接。
绝缘体2上的环形凸起201或环形凹槽202，为了保证绝缘体2位于外导体1的轴向定位，因此需要与第二腔体102的内壁面抵接，防止绝缘体2在工作的时候径向移动，导致内导体7与外导体1的距离不均匀，各个位置的屏蔽效果不一致，无法保证了数据传输的精准度。绝缘体2与第二腔体102的内壁抵接部分只限于限位功能，不会因为具体如何抵接或者形状的不同来影响内导体7卡接在绝缘体2内部进行导电工作。
在一种实施方式中，绝缘体2材质为塑料或橡胶，外导体1为板状金属材料一体冲压卷曲成型，绝缘体2一体注塑成型在外导体1内。
绝缘体2一体注塑在外导体1的内部，外导体1为一体成型的金属，便于安装，先注塑，在把绝缘体2卷曲在内部成型，最后内导体7卡接在绝缘体2的内部，组装快速便捷，绝缘体2的材质包括塑料或橡胶等。
在一种实施方式中，绝缘体2材质为塑料或橡胶并预制成型，外导体1为板状金属材料，所述板状金属材料一体冲压成型后，再将绝缘体2包裹其中卷曲成型。
绝缘体2是通过板状的外导体1机器冲压卷曲在内部，安装速度快，先把绝缘体2加工出来并且预制成型，然后把外导体1一体冲压出来，之后把绝缘体2放入到外导体1上并且与绝缘体2抵接或卡接的位置，之后通过机器把外导体1冲压成型，把绝缘体2卷曲在内部。
外导体1一体冲压成型后再将绝缘体2包裹其中，简化了绝缘体2安装到外导体1中的加工步骤，提高加工效率。另外不同直径的腔体对绝缘体2进行限位，从而使绝缘体2固定在外导体1中，定位准确，同轴度高且绝缘体不易松动或移动。
绝缘体2的设置方式可以采用组装或一体注塑，能够一次性加工成型，避免了人工组装的过程，自动化程度高，极大的提高了生产效率。
在一种实施方式中，如图1所示，一种连接器，包括内导体7、护套6和外导体组件，所述外导体组件设置在护套6中，内导体7卡接在绝缘体2内。
外导体组件包括绝缘体2和外导体1，外导体1通过第二腔体102对应的凸台或者凹槽卡接在护套6内，防止工作过程脱落，内导体7插入到绝缘体2中，并通过绝缘体2限定在外导体1中并与外导体1同轴，从而保证外导体1的屏蔽效果，保证了数据传输的精准度。
在一种实施方式中，如图1所示，绝缘体2内轴向设置插接腔，所述插接腔内壁设置至少一个卡接槽，内导体7上设有与所述卡接槽卡接的至少一个倒刺8。
绝缘体2内加工插接腔，便于内导体7与绝缘体2的卡接，内导体7上倒刺8与插接腔上的卡接槽卡接，可以防止内导体7位于插接腔内轴向运动。
在一种实施方式中，如图1所示，所述外导体组件外周设置与第二腔体102对应的凸台或凹陷，护套6内壁上设置与所述凸台或所述凹陷对应配合的卡槽或卡环，所述凸台与所述卡槽匹配安装，或，所述凹陷与所述卡环匹配安装，以实现所述外导体组件在护套6内的轴向定位。
外导体1上的凸台或者凹槽是通过内部的绝缘体2进行决定的，环形凸起201和环形凹槽202，对应到外导体1的凸台和凹槽，之后外导体1的凸台和凹槽与护套6内的卡槽和卡环对应卡接，以实现外导体组件在护套6内的轴向定位，来保证定位精度。另外不需要在外导体1的侧面冲压与护套6连接的连接片，筒状的外导体1表面完全封闭，屏蔽效能明显提高，从而保证了数据传输的精准度。
以上所述仅为本发明示意性的具体实施方式，并非用以限定本发明的范围。任何本领域的技术人员，在不脱离本发明的构思和原则的前提下所作的等同变化与修改，均应 属于本发明保护的范围。
