Definitions

  • the present application relates to the technical field of connector design, and more specifically, to a connector shielding sleeve positioning structure.
  • Electrical connectors can be used in transportation, communications, home appliances, medical products and other products. With the rapid development of the technical level of products in the supporting fields of electrical connectors and the rapid growth of the market, the development of connector technology is strongly promoted. So far, electrical connectors have developed into a series of professional products with a complete range of products, various specifications and models, various structures and standard system specifications. With the rapid development of modern science and technology, miniaturization has also become an important demand on the basis of the high-performance demand trend of electrical connectors.
  • the connecting terminals in the electrical connector are responsible for transmitting data information. The interference of external signals on the connecting terminals will cause distortion of signal transmission. Therefore, shielding sleeves are set outside the connecting terminals and inside the connector to shield electromagnetic interference.
  • the shielding sleeve is installed in the connector and is movable in the axial direction. Therefore, a positioning piece is required to ensure that the shielding sleeve is fixed in the connector. When the shielding sleeve needs to be removed, the positioning piece must be removed first.
  • general positioning pieces are realized by plastic mold molding. Because the plastic material is soft and has poor strength, a thicker wall thickness is generally required to ensure the fixing strength requirements, resulting in a large volume of the connector body, which cannot meet the demand for miniaturization of products. At the same time, it is difficult to set a knot for installing the positioning member on the miniaturized connector. Therefore, there is an urgent need in the prior art for a positioning member that can be installed by connecting with a shielding sleeve and has a smaller size.
  • One object of the present application is to provide a connector solution that is not easy to fall off and can be miniaturized.
  • a connector shielding sleeve positioning structure comprising: a connector sheath, a shielding sleeve and a metal positioning piece;
  • the connector sheath comprises a cavity and a slot body vertically communicating with the cavity;
  • the shielding sleeve is arranged in the cavity
  • the shielding sleeve has a limiting section formed by a radial depression
  • the metal positioning member is in the form of a sheet, and comprises two elastic arms arranged opposite to each other, and a connecting portion connecting the two elastic arms;
  • the connecting portion is arranged in the groove body, the two elastic arms are clamped on the limiting section, and the distance between the free ends of the two elastic arms is less than or equal to the diameter of the limiting section.
  • the metal locating piece can meet the high strength and mechanical performance test requirements in a very thin condition due to the metal material. At the same time, the embracing structure of the metal locating piece is increased, and the distance between the free ends is smaller. When the connector is inverted, the metal locating piece will not fall off due to the constraint of the free end, thereby providing secondary protection for the connector and strengthening the reliability and stability of the connector itself.
  • the solution provided in the present application also includes the possibility of selecting a metal locating piece made of phosphor bronze with better elasticity or a metal locating piece made of stainless steel with better rigidity according to actual conditions.
  • FIG. 1 is a schematic structural diagram of a connector shielding sleeve positioning structure according to an embodiment of the present application.
  • FIG. 2 is a schematic diagram of a connector sheath structure of a connector shielding sleeve positioning structure according to an embodiment of the present application.
  • FIG. 3 is a schematic diagram of the shielding sleeve structure of the connector shielding sleeve positioning structure according to an embodiment of the present application.
  • FIG. 4 is a schematic diagram of the metal positioning member structure of the connector shielding sleeve positioning structure according to an embodiment of the present application.
  • the connector shielding sleeve positioning structure includes: a connector sleeve 1, a shielding sleeve 2 and a metal positioning piece 3;
  • the connector sleeve 1 includes a cavity 11 and a groove body 12 vertically connected to the cavity 11;
  • the shielding sleeve 2 is arranged in the cavity 11;
  • the shielding sleeve 2 has a limiting section 21 formed by a radial recess;
  • the metal positioning piece 3 is sheet-shaped, including two elastic arms 31 arranged opposite to each other (for example, symmetrically along the longitudinal center axis of the metal positioning sheet), and a connecting part 32 connecting the two elastic arms 31;
  • the connecting part 32 is arranged in the groove body 12, the two elastic arms 31 are clamped on the limiting section 21, and the distance between the two free ends 311 of the two elastic arms 31 is less than or equal to the diameter of the limiting section 21.
  • the terminals in the connector are used for electrical connection of different electrical connection ends, and the shielding sleeve 2 is used to shield the interference of the signal.
  • the shielding sleeve 2 is longitudinally arranged in the cavity 11 of the connector sheath 1, and there is a groove 12 perpendicular to the cavity 11 on the side of the cavity 11, and the metal positioning piece 3 passes through the groove 12.
  • Its connecting part 32 is located in the groove 12, and the elastic arm 31 is clamped on the limiting section 21 of the shielding sleeve 2, and the diameter of the limiting section 21 is smaller than the diameter of other parts of the shielding sleeve 2.
  • the shielding sleeve 2 When the elastic arm 31 is clamped on the limiting section 21, the shielding sleeve 2 is fixed in the longitudinal direction and cannot move, thereby achieving a positioning effect. Because of the metal material, the metal positioning piece 3 can meet higher strength and mechanical performance test requirements in a very thin case. At the same time, the embracing structure of the metal positioning piece 3 is increased, and the distance between the two free ends 311 is smaller. When the connector is inverted, it is constrained by the free end 311, and the metal positioning piece 3 will not fall off, thereby providing secondary protection for the connector and strengthening the reliable stability of the connector itself.
  • the metal positioning member 3 is made of phosphor bronze alloy.

  • the thickness of the metal locator 3 can be, for example, 0.4mm-3mm.
  • the metal locator 3 made of phosphor bronze alloy has the characteristics of slightly lower rigidity but better elasticity compared to stainless steel. Therefore, the thickness of the metal locator 3 is a consideration factor of this application. If the thickness is too large, the elastic arm is not easy to deform and cannot be plugged in. If the thickness is too small, the hardness of the metal locator 3 is insufficient, which easily leads to irreversible bending of the elastic arm 31 when it is connected with the limit section 21. In order to find a suitable thickness of the metal locator 3 made of phosphor bronze, the applicant conducted relevant experiments.
  • the experimental method is to plug metal locators 3 of different thicknesses with the same shielding sleeve 2 under a thrust of 120N. If a crease is found on the elastic arm 31 after plugging, it is unqualified. If it cannot be plugged in due to too large thickness, it is also unqualified.

  • the ratio of the minimum distance between the two free ends 311 of the metal positioning member 3 to the diameter of the limiting segment 21 is 1:1.15 to 1:1.6.

本申请要求于2022年11月03日递交的申请号为202222927698.4的中国实用新型专利申请的优先权，并引用上述专利申请公开的全部内容作为本申请的一部分。
技术领域
本申请涉及连接器设计技术领域，更具体地，涉及一种连接器屏蔽套筒定位结构。
背景技术
电连接器可应用于交通、通信、家电及医疗等产品中，在电连接器的配套领域产品技术水平快速发展及市场的快速增长情况下，强有力的推动着连接器技术的发展。至目前为止，电连接器已发展为产品种类齐全、规格型号繁多、结构多种多样以及标准体系规范的系列化和专业化的产品。随着现代科技的飞速发展，电连接器有高性能需求趋势的基础上，小型化也成为了重要需求。电连接器内的连接端子担负着传递数据信息的任务，连接端子受到外界信号干扰会造成信号传输的失真的情况，因此会在连接端子外部、连接器的内部设置屏蔽套筒来屏蔽电磁干扰。而屏蔽套筒安装在连接器内，其轴向方向是可移动的，因此需要定位件来保证屏蔽套筒固定在连接器内，当需要拆卸屏蔽套筒前需先拆卸定位件。目前一般的定位件通过塑胶模具成型来实现的，由于塑胶材质较软，强度较差，一般需要较厚的壁厚才能保证固定强度要求，从而造成连接器本体体积较大，无法满足产品向小型化发展的需求。同时，小型化的连接器上很难设置用于安装定位件的结。因此，现有技术中亟需一种能够通过与屏蔽套筒连接进行安装且尺寸较小的定位件。
发明内容
本申请的一个目的是提供一种不易脱落且能够进行小型化设计的连接器方案。
连接器屏蔽套筒定位结构，包括：连接器护套、屏蔽套筒和金属定位件；
所述连接器护套包括腔体和与所述腔体垂直相通的槽体；
所述屏蔽套筒设置在所述腔体内；
所述屏蔽套筒具有径向凹陷形成的限位段；
所述金属定位件为片状，包括相对设置的两个弹性臂，和连接两个所述弹性臂的连接部；
所述连接部设置在所述槽体内，两个所述弹性臂卡接在所述限位段上，两个所述弹性臂的自由端的距离小于或等于所述限位段的直径。
本申请的有益效果是：金属定位件因为金属材质的缘故在非常薄的情况下能够满足较高的强度和力学性能测试要求。同时增加金属定位件的环抱结构，自由端间的距离更小。当连接器倒置的时候，受到自由端的约束，金属定位件也不会脱落，从而对连接器提供二次保护，对连接器本身的可靠稳定性起到加强作用。本申请提供的方案中还包括了可以根据实际情况选择弹性更好的磷青铜材质的金属定位件或刚性更好的不锈钢材质的金属定位件。
通过以下参照附图对本申请的示例性实施例的详细描述，本申请的其它特征及其优点将会变得清楚。

具体实施方式
现在将参照附图来详细描述本申请的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，上述技术、方法和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不 是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
连接器屏蔽套筒定位结构，如图1-图4所示，包括：连接器护套1、屏蔽套筒2和金属定位件3；连接器护套1包括腔体11和与腔体11垂直相通的槽体12；屏蔽套筒2设置在腔体11内；屏蔽套筒2具有径向凹陷形成的限位段21；金属定位件3为片状，包括相对设置(例如沿着金属定位片的纵向中心轴对称)的两个弹性臂31，和连接该两个弹性臂31的连接部32；连接部32设置在槽体12内，两个弹性臂31卡接在限位段21上，两个弹性臂31的两个自由端311之间的距离小于或等于限位段21的直径。
连接器内的端子用于不同电连接端的电连接，屏蔽套筒2用于屏蔽信号的干扰，屏蔽套筒2纵向设置在连接器护套1的腔体11内，腔体11的侧方有与之垂直的槽体12，金属定位件3穿过槽体12。其连接部32位于槽体12内，弹性臂31卡接在屏蔽套筒2的限位段21上，限位段21的直径小于屏蔽套筒2其他部分的直径。当弹性臂31卡接在限位段21后，屏蔽套筒2在纵向方向被固定，不能移动，从而起到定位效果。金属定位件3因为金属材质的缘故在非常薄的情况下能够满足较高的强度和力学性能测试要求。同时增加金属定位件3的环抱结构，两个自由端311之间的距离更小，当连接器倒置的时候，受到自由端311的约束，金属定位件3也不会脱落，从而对连接器提供二次保护，对连接器本身的可靠稳定性起到加强作用。
在一些实施例中，金属定位件3的材质为磷青铜合金。磷青铜是铜与锡、磷的合金，质地坚硬，主要用作耐磨零件和弹性元件，同时该合金具有优良机械加工性能及成屑性能，可迅速缩短零件加工时间。由磷青铜合金制作的金属定位件3具有更好的弹性使其便于与限位段21卡接。
进一步的，在金属定位件3的材质为磷青铜合金的情况下，金属定位件3的厚度例如可以为：0.4mm-3mm。用磷青铜合金制作的金属定位件3相对于不锈钢材质具有刚性稍差但是弹性更好的特性，因此金属定位件3的厚度是本申请的考虑要素，如果厚度过大则弹性臂不易发生形变无法插接，如果厚度过小则金属定位件3的硬度不足，容易导致弹性臂31在与限位段21卡接时出现不可逆的弯折。为了寻找合适的磷青铜材质的金属定位件3的厚度，申请人进行了相关实验，实验方法为用不同厚度的金属定位件3与相同的的屏蔽套筒2在120N的推力下插接，如果插接后发现弹性臂31出现折痕，则为不合格，如果因为厚度太大无法插接，也为不合格。得到的实验结果如表1所示。
表1：磷青铜材质的金属定位件3的厚度对能否插接及弹性臂31是否出现折痕 的影响
如表1所示，当磷青铜材质的金属定位件3的厚度小于0.4mm，弹性臂31在插接后出现折痕为不合格，同时，当磷青铜材质的金属定位件3的厚度大于3mm时，金属定位件3无法与屏蔽套筒2插接，因此申请人可选磷青铜材质的金属定位件3的厚度为0.4mm-3mm。
在一些实施例中，金属定位件3的材质例如可以为不锈钢。相对于磷青铜合金，不锈钢具有更高的强度，但是弹性稍差。
进一步的，在金属定位件3的材质为不锈钢的情况下，金属定位件3的厚度为：0.2mm-2.6mm。申请人采用了和前面一样的实验方法来选择合适的不锈钢材质的金属定位件3的厚度，得到的实验结果如表2所示。
表2：不锈钢材质的金属定位件3的厚度对能否插接及弹性臂31是否出现折痕的影响
如表2所示，当不锈钢材质的金属定位件3的厚度小于0.2mm，弹性臂31在插接后出现折痕为不合格，同时，当不锈钢材质的金属定位件3的厚度大于2.6mm时，金属定位件3无法与屏蔽套筒插接，因此申请人可选不锈钢材质的金属定位件3的厚度为0.2mm-2.6mm。
在一些实施例中，金属定位件3两个自由端311间的最小距离与限位段21的直径的比为：1：1.15至1:1.6。如果两个自由端311间的最小距离与限位段21的直径的比过小， 则金属定位件3会较难甚至无法在120N的推力下插接限位段21，如果这个比值过大，则在摆动实验中金属定位件3会更容易与限位段21脱离，得到实验结果如表3所示。
表3：金属定位件3两个自由端311间的最小距离与限位段21的直径的比对能否插接及能否脱离的影响
如表3所示，当金属定位件3两个自由端311间的最小距离与限位段21的直径的比小于1：1.6时，即自由端311之间的距离过小，导致金属定位件3无法插接限位段21，所以为不合格。当金属定位件3两个自由端311间的最小距离与限位段21的直径的比大于1：1.15时，即自由端311之间的距离过大，导致在摆动实验中金属定位件3与限位段21分离，也为不合格。因此，申请人可选金属定位件3两个自由端311间的最小距离与限位段21的直径的比为：1：1.15至1:1.6。
在一些实施例中，槽体12的侧壁设置有卡接槽，连接部32的两侧设置有用于卡接在卡接槽内的至少一个卡接凸起33。卡接凸起33卡接在卡接槽内能够使金属定位件3安装得更牢固。
在一些实施例中，两个弹性臂31包括弧形段312，弧形段312具有与限位段21至少表面匹配的弧形面。也就是说弧形段312的内表面为完全与限位段21贴合的圆弧形，这样连接更紧固，能够防止弹性臂31抖动发出异响。
在一些实施例中，两个自由端311相对的表面设置有导向面。导向面能够方便自由端311与限位段21的插接，防止自由端311与限位段21刚性接触划伤屏蔽套筒2的表面。
在一些实施例中，连接部32与槽体12过盈配合。过盈配合能够使连接部32与槽体12连接更牢固还能具有防水防尘功能。
虽然已经通过例子对本申请的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本申请的范围。本领域的技术人员应该理解，可在不脱离本申请的范围和精神的情况下，对以上实施例进行修改。本申请的范围由所附权利要求来限定。
