Description

一种USB接插件及其金属外壳
【技术领域】
本发明涉及连接器技术领域，特别是涉及一种USB接插件及其金属外壳。
【背景技术】
通用串行总线(Universal Serial Bus，USB)是一种用于直流供电和通讯的接口标准，已广泛应用于手机、平板电脑、笔记本电脑、微型计算机、数码照相机等电子产品中。
目前的USB数据接口在使用过程中，当用手捏其金属外壳时，其接插口处容易产生变形（金属内凹），而金属外壳内的数据触点间隙非常小，这样使得数据触点容易产生位置偏移或者松散，造成数据触点之间相互接触而中断数据传输，影响到数据传输的稳定性。
【发明内容】
本发明主要解决的技术问题是提供一种USB接插件及其金属外壳，能够提高数据传输的稳定性。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种USB接插件，包括金属外壳及收容于所述金属外壳内的电子组件；其中，所述金属外壳的接插口处设有加强结构。
其中，所述金属外壳的接插口包括两平行直边以及连接两平行直边的两弧形侧边，所述加强结构设置于所述两平行直边。
其中，所述加强结构是所述金属外壳在其两平行直边处的弯折结构。
其中，所述弯折结构是所述金属外壳向内侧弯折所形成的折叠结构。
其中，所述弯折结构是所述金属外壳向外侧弯折所形成的折叠结构，并且所述金属外壳的外侧表面经压平处理。
其中，所述金属外壳的接插口外侧表面为圆弧结构。
其中，所述电子组件包括邻近所述金属外壳的接插口的基础塑胶件、位于所述基础塑胶件表面的多个数据传输触点、远离所述金属外壳的接插口的电路板以及传输线，所述多个数据传输触点和传输线分别与所述电路板焊接连接。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种USB接插件的金属外壳，包括：金属壳体，所述金属壳体的接插口处设有加强结构。
其中，所述金属壳体的接插口包括两平行直边以及连接两平行直边的两弧形侧边，所述加强结构设置于所述两平行直边，所述加强结构是所述金属外壳在其两平行直边处的弯折结构。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种USB接插件的金属外壳，包括：金属壳体，所述金属壳体包括位于接插口处的第一壳体部分和远离所述接插口的第二壳体部分，所述第一壳体部分包括两平行直边以及连接两平行直边的两侧边，所述第一壳体部分的两平行直边处厚度大于所述第二壳体部分的厚度。
本发明的有益效果是：区别于现有技术的情况，本发明在USB接插件的金属外壳的接口处设置加强结构，使得金属外壳受到压力时不会轻易产生变形，保证金属外壳内部的数据触点位置稳定，从而提高数据传输的稳定性。
【附图说明】
图1是本发明一种USB接插件一实施方式的结构剖面图；
图2是本发明一种USB接插件的金属外壳一实施方式的结构示意图；
图3是本发明一种USB接插件另一实施方式的结构剖面图；
图4是本发明一种USB接插件的金属外壳另一实施方式的结构示意图。
【具体实施方式】
如图1，本发明实施方式提供一种USB接插件，包括金属外壳1及收容于金属外壳1内的电子组件2；本发明实施方式的USB接插件为本领域常规的USB接插件，例如USB 3.1 Type C型等，电子组件通过各种连接方式安装到金属外壳中，用于传输数据；其中，本发明实施方式的金属外壳1的接插口处设有加强结构11，接插口是指金属外壳的端部，该处的强度一般都比金属外壳其它部分的强度弱，加强结构11用于加强接插口处的机械强度，使得金属外壳1的接插口不易受到外力而产生形变；本发明实施方式中金属外壳1可使用不锈钢等强度较好且耐腐蚀的材料。
区别于现有技术，本发明实施方式在USB接插件的金属外壳1的接口处设置加强结构11，使得金属外壳1受到压力时不会轻易产生变形，保证金属外壳1内部的数据触点位置稳定，从而提高数据传输的稳定性。
其中，如图2，金属外壳1的接插口包括两平行直边12以及连接两平行直边12的两弧形侧边13，加强结构11设置于两平行直边12。
一般地，两平行直边12的长度要大于两弧形侧边13的长度，而且弧形设计能提高弧形侧边13的强度，所以较长的两平行直边12的强度会比较弱，而且内部的数据触点等电子组件2也都设置在两平行直边12所在的金属外壳1面上，本发明实施方式在两平行直边12上设置加强结构11，增加两平行直边12的机械强度，使得两平行直边12受到按压时不易变形，保证金属外壳1内的电子组件2位置的稳定。在本发明实施方式中，设置加强结构11后，两平行直边12之间的距离应当大于1.3毫米，以满足标准数据接口尺寸标准。
其中，如图2，本发明实施方式的加强结构11是金属外壳1在其两平行直边12处的弯折结构111。
将平行直边12所在的金属外壳1部分设置为长于两弧形侧边13所在的金属外壳1部分，并将两平行直边12所在的金属外壳1部分的伸出两弧形侧边13之外的部分弯折，使其叠合在未弯折的平行直边12所在的金属外壳部分上，形成两层金属的结构，提高强度，同时弯折的设计能进一步提高两层金属结构的强度，从而加强金属外壳1的接插口处的机械强度，使其受到按压时不易产生形变。当然，金属外壳1的接插口平行直边12处弯折的部分的厚度并不一定要与未弯折的部分厚度相同，本发明实施方式中可以将弯折部分的厚度设置为比未弯折的部分的厚度更厚，从而进一步提高接插口处的机械强度；本发明实施方式中两平行直边12所在的金属外壳1部分弯折后应保证两平行直边12与弧形侧边的连接处过渡自然，使得金属外壳1的接插口整齐、光滑。
其中，如图2，本发明实施方式的弯折结构111是金属外壳1向内侧弯折所形成的折叠结构。
将弯折结构111设计为金属外壳1向内弯折可保证金属外壳1外表面的平整，使USB接插件易于插入。
其中，本发明另一实施方式中，弯折结构是金属外壳1向外侧弯折所形成的折叠结构（未图示），并且金属外壳1的外侧表面经压平处理。
将金属外壳1向外弯折后，会使得金属外壳1外表面形成不平整的结构，所以这时应当将金属外壳1的外侧表面进行压平处理，使得金属外壳1的外侧表面平整光滑，便于USB接插件的插入和抽出。
其中，如图2，本发明实施方式的金属外壳1的接插口外侧表面为圆弧结构14。
将金属外壳1的接插口外侧表面设为圆弧结构14，即形成圆弧倒角，能使得USB接插件在接插时方便插入；本发明实施方式在金属外壳1的接插口的平行直边12和弧形侧边13的外侧表面均设置圆弧结构14，使得整个接插口外表面具有圆弧倒角。
其中，如图3，本发明实施方式的电子组件2包括邻近金属外壳1的接插口的基础塑胶件21、位于基础塑胶件21表面的多个数据传输触点22、远离金属外壳1的接插口的电路板23以及传输线24，多个数据传输触点22和传输线24分别与电路板23焊接连接。
本发明实施方式在金属外壳1内设置基础塑胶组件21，并在基础塑胶组件21上安装用于传输数据的传输触点22、电路板23及传输线24，并通过电连接的方式将其连接；其中，在一实施方式中，金属外壳1的接插口处弯折结构111向内弯折的长度正好使得基础塑胶组件21沿着金属外壳1弯折部分的内端部安装，即将金属外壳1弯折部分的内端面作为基础塑胶组件21的组装定位面25，这样既可提高金属外壳1的接插口的机械强度，又方便基础塑胶组件21在金属外壳1内的组装定位。
本发明另一实施方式提供一种USB接插件的金属外壳，其用于收容传输数据的电子组件，如图2，本发明实施方式的USB接插件的金属外壳包括金属壳体1，金属壳体的接插口处设有加强结构11。
区别于现有技术，本发明实施方式在USB接插件金属外壳的金属壳体的接口处设置加强结构11，使得金属壳体受到压力时不会轻易产生变形，保证金属壳体内部的数据触点位置稳定，从而提高数据传输的稳定性。
其中，本发明实施方式的金属壳体的接插口包括两平行直边12以及连接两平行直边12的两弧形侧边13，加强结构11设置于两平行直边12，加强结构11是金属外壳在其两平行直边12处的弯折结构111。
本发明又一实施方式提供一种USB接插件的金属外壳，其用于收容传输数据的电子组件，如图4，本发明实施方式的USB接插件的金属外壳包括金属壳体3，金属壳体3包括位于接插口处的第一壳体部分31和远离接插口的第二壳体部分32，第一壳体部31分包括两平行直边311以及连接两平行直边311的两侧边312，第一壳体部分31的两平行直边处311厚度大于第二壳体部分32的厚度。
区别于现有技术，本发明实施方式将USB接插件金属外壳的金属壳体3靠近其端部的第一壳体部分31的平行直边311厚度设置为大于远离端部的第二壳体部分32的厚度，使得第一壳体部分31的机械强度大于第二壳体部分32的机械强度，从而使得金属外壳受到压力时不会轻易产生变形，保证金属外壳内部的数据触点位置稳定，从而提高数据传输的稳定性。
以上仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本发明的专利保护范围内。
