在本实施方式中，所述引脚212包括多个第一引脚212a及多个第二引脚212b。当所述引脚212包括第一引脚212a时，所述USB接口20为第一规格的USB接口20，当所述引脚212包括第二引脚212b时，所述USB接口20为第二规格的USB接口20。其中，所述第一规格与所述第二规格不同。在本实施方式中，所述第一规格为3.0规格，所述第二规格为2.0规格，可以理解地，在其他实施方式中，所述第一规格及所述第二规格也可以为其他规格。由所述USB接口20不同规格时的规定，当USB接口20为3.0规格的接口时，所述第一引脚212a的个数为5个，当所述USB接口20为2.0规格的接口时，所述第二引脚212b的个数为4个。在本实施方式中，以所述引脚212支持第一规格及第二规格的USB接口20为例进行介绍，在其他实施方式中，所述引脚212也可仅为仅支持一种规格的USB接口20，比如，所述引脚212仅支持3.0规格的USB接口20。在其他实施方式中，所述引脚212还可支持更多规格的USB接口20。可以理解地，所述引脚212的可以支持的USB接口20的规格并不构成对本申请的限定。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不 同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。
所述主体210还包括与所述引脚212相连的导电部213。所述导电部213与所述引脚212电连接，且部分所述导电部213显露于所述主体部211，所述导电部213用于将所述引脚212电连接并至所述电路板。所述导电部213与所述引脚212可以为但不仅限于为一体结构。所述导电部213的显露于所述主体部211的部分的厚度大于或等于100um，以满足所述导电板焊接到所述电路板上的要求。

相较于传统技术，本申请的USB接口20中设置有屏蔽件220，所述屏蔽件220覆盖所述引脚212的至少部分，以使得所述屏蔽件220对所述USB接口20的引脚212中传输的信号进行屏蔽，以减少甚至避免所述USB接口20中的引脚212中传输的信号对USB接口20周围的其他信号的传输造成干扰。
在一实施方式中，所述屏蔽件220还用于接地。所述屏蔽件220接地可进一步提升所述屏蔽件220的屏蔽效果，进一步减少所述USB接口20中的引脚212中传输的信号对USB接口20周围的其他信号的传输造成干扰。
下面对所述屏蔽件220的具体实施方式进行介绍。请一并参阅图6及图7，图6为本申请一实施方式中屏蔽件的结构示意图；图7为图6中提供的屏蔽件与主体组装后的示意图。所述屏蔽件220包括第一壳体221。所述第一壳体221包括第一本体2211、至少一个弹片2212、及第一接地引脚2213。所述第一本体2211具有第一收容空间221a及至少一个开口221d，所述第一收容空间221a用于收容所述主体210，且所述主体210固定于第一本体2211，所述开口221d连通所述第一收容空间221a；所述至少一个弹片2212设置于所述第一本体2211上，且自所述开口221d部分伸入所述第一收容空间221a。所述第一接地引脚2213连接于所述第一本体2211，且所述第一引脚2213还用于接地。

下面对弹片2212进行详细介绍。每个弹片2212的一部分自所述开口221d深入所述第一收容空间 221a。所述弹片2212用于所述USB接口20与外部设备7通过USB插头71插接时，与所述USB插头71良好接触。具体地，当外部设备7通过USB插头71插入所述USB接口20时，压迫所述弹片2212变形，依靠所述弹片2212的变形力，可保证所述USB接口20与所述USB插头71的良好连接，进而所述USB插头71可通过所述第一接地引脚2213接地，可实现所述USB接口20与所述USB插头71插接时对USB接口20传输的数据的屏蔽作用。此外，由于所述外部设备7通过USB插头71插入所述USB接口20时，所述弹片2212会产生变形力，因此，可以方便用户判断是否将外部设备7插所述USB接口20或者拔出所述USB接口20，可避免外部设备7不能良好的插入所述USB接口20。进一步地，由于所述外部设备7通过USB插头71插入所述USB接口20时，所述弹片2212会产生变形力，因此，可提升用户在将外部设备7插入或拔出所述USB接口20中时的拔插手感。所述至少一个弹片2212与所述第一本体2211为一体结构，或者为分体结构。在本实施方式中，所述第一本体2211的形状大致为两端开设有口子的长方体。所述周侧壁221b的个数为4个，所述弹片2212的个数为6个，其中，宽度较大的两个周侧壁221b上各设置有2个弹片2212，宽度较小的两个周侧壁上各设置有1个弹片2212。可以理解地，在其他实施方式中，所述弹片2212的个数也可以为其他数目，在此不做限定。
在实施方式中，所述第一壳体221还包括定位引脚2214。所述定位引脚2214连接于所述第一本体2211，所述定位引脚2214用于所述USB接口20电连接到电路板上时的定位。

由上述描述可见，所述第一壳体221收容于所述第二壳体222内，因此，在本实施方式中，所述第一壳体221也称为内壳，所述第二壳体222也称为外壳。所述第二壳体222的材质可以为但不仅限于具有电磁屏蔽作用的材质，比如金属，举例而言，所述第二壳体222的材质可以为黄铜。所述第二壳体222通常具有较好的延伸率，以保证形成所述避让部2222时的良率(比如良率大于或等于90％)。举例而言，所述第二壳体222的延伸率可以达到30％，所述第二壳体222的硬度可以为1/2H。
由前面描述可知，当外部设备7通过USB插头71插入所述USB接口20中时，所述弹片2212会产生变形，因此，设置所述避让部2222与所述第二本体2221形成避让空间，可对所述弹片2212变形时进行避让，以免所述弹片2212缺少避让空间而无法变形导致的所述USB插头71无法正常插入所述USB接口20。

在一实施方式中，请参阅图16，图16为本申请又一实施方式提供的USB接口的示意图。在本实施方式中，所述第一本体2211与所述第二本体2221之间通过多个第一焊点2216焊接。所述第二本体2221与所述第三本体2231之间通过多个第二焊点2225焊接。相邻的两个第一焊点2216之间的距离小于预设距离，相邻的两个第二焊点2225之间的距离小于所述预设距离，其中，所述预设距离等于所述USB接口20传输的数据信号的波长的四分之一。
在本实施方式中，通过所述第一焊点2216将所述第一本体2211与所述第二本体2221焊接，可实现所述第一壳体221与所述第二壳体222之间的固定，提升所述第一壳体221与所述第二壳体222固定时的牢固性，相邻的两个第一焊点2216之间的距离小于所述USB接口20传输的数据信号的波长的四分之一，可实现对所述USB接口20传输的数据信号的屏蔽作用。当相邻的两个第一焊点2216之间的距离小于所述USB接口20传输的数据信号的波长的四分之一时，相邻的两个第一焊点2216之间的距离非常小，USB接口20传输的数据信号无法通过相邻的两个第一焊点2216之间的缝隙泄露到所述第二壳体222的外面，进一步提升所述屏蔽件220的屏蔽效果。同样地，当相邻的两个第二焊点2225之间的距离小于所述USB接口20传输的数据信号的波长的四分之一时，相邻的两个第二焊点2225之间的距离非常小，USB接口20传输的数据信号无法通过相邻的两个第二焊点2225之间的缝隙泄露到所述第二壳体222及第三壳体223的外面，进一步提升所述屏蔽件220的屏蔽效果。可以理解地，相邻的两个第一焊点2216的距离与相连的两个第二焊点2225之间的距离可以相等也可以不等。所述USB接口20传输的数据信号可以为但不仅限于为频率为2.5GHz的方波信号，其中所述数据信号的波长为1/f，其中，f为频率。
请参阅图17及图18，图17为本申请再一实施方式提供的USB接口在一角度下的组装示意图；图18为图17中所示的USB接口在另一视角下的组装示意图。在本实施方式中，所述屏蔽件220中可省略所述第一壳体221，仅仅包括第二壳体222及第三壳体223。具体地，所述屏蔽件220为环绕所述主体210的周侧面210a设置的中空的壳体，所述屏蔽件220上设置有连接部220c，所述连接部220c固定且凸出于所述屏蔽件220的内侧壁。
所述屏蔽件220的材质可以为但不仅限于具有电磁屏蔽作用的材质，比如金属，举例而言，所述屏蔽件220的材质为磷青铜。所述连接部220c凸出于所述屏蔽件220的内侧壁，所述连接部220c用于当外部设备7通过USB插头71插入所述USB接口20时，保证所述USB接口20与所述USB插头71的连接，以免所述USB插头71从所述USB接口20上脱落。
本申请还提供一种电子设备1，下面对本申请提供的电子设备1进行详细介绍。请参阅图19，图19为本申请一实施方式提供的电子设备的示意图。所述电子设备1可以为但不仅限于为手机、电脑、用户终端设备(Customer Premises Equipment，CPE)等具有USB接口20的设备。所述电子设备1包括电路板30及前面任意实施方式所述的USB接口20，USB接口20固定于电路板30，且电连接于所述电路板30的地极。所述USB接口20还电连接于所述电路板30中的其他线路，以实现所述USB接口20中的数据信号的传递。
请参阅图20及图21，图20为本申请又一实施方式提供的电子设备的示意图；图21为图20中的立体分解图。所述电子设备1还包括：屏蔽罩40，所述屏蔽罩40设置于所述电路板30背离所述USB接口20的一侧，且所述屏蔽罩40对应所述USB接口20连接于所述电路板30的部位设置。
当所述USB接口20连接于所述电路板30时，所述USB接口20连接于所述电路板30的部位(比如，第一接地引脚2213，第二接地引脚2223，第三接地引脚2234、及导电部213、定位引脚2214)等会均等效于微天线，电子设备1中的其他天线(比如，WIFI天线，蓝牙天线等，例如，后面提到的第一天线120、第二天线140、第三天线160等)进行干扰，因此，通过设置屏蔽罩40对应所述USB接口20连接于所述电路板30的部位设置，可避免所述USB接口20连接于所述电路板30的部位等对电 子设备1中的其他天线的干扰。
在本实施方式中所述屏蔽罩40包括：支架410及屏蔽盖420。所述支架410固定于所述电路板30背离所述USB接口20的一侧且对应所述USB接口20连接于所述电路板30的部位设置，所述支架410具有开口。所述屏蔽盖420固定于所述支架410，且密封所述支架410的开口。
在本实施方式中，所述屏蔽罩40包括支架410及屏蔽盖420，支架410开设有开口，所述开口可作为观测窗口，便于观察到所述USB接口20连接于所述电路板30的部位是否与所述电路板30连接良好，若连接良好，再将所述屏蔽盖420放置在所述支架410的开口上，并密封所述支架410的开口。通常情况下，所述USB接口20的组装产线和测试USB接口20是否电性连接于电路板30的产线是两个独立的产线。换而言之，当进行USB接口20组装时，不能对USB接口20是否电性连接于所述电路板30进行测试的。本申请通过将屏蔽罩40设置为两部分，在支架410上开设开口做为观察USB接口20中的连接至所述电路板30的部位是否连接到电路板30的观察窗，通过观察USB接口20连接至所述电路板30的部位与电路板30连接时所需要的连接件(比如焊锡)的情况，可初步判断USB接口20连接至所述电路板30的部位与电路板30之间是否存在漏焊或者焊料不足等情况。可将USB接口20连接至所述电路板30的部位与电路板30之间是否存在漏焊或者焊料不足的情况的USB接口20与电路板30的组装件预先剔除，将符合条件的USB接口20与电路板30的组装件保留，再进行屏蔽盖420的固定，有助于提升所述USB接口20组装的良率。
在其他实施方式中，所述屏蔽罩40可以为一体结构，以便提升所述屏蔽罩40的屏蔽效果。
下面以所述电子设备1为用户终端设备(Customer Premises Equipment，CPE)为了进行介绍。当所述电子设备1为CPE时，所述外部设备7可以为具有USB插头71的U盘或者具有USB插头71的移动硬盘。所述终端设备(比如，手机)5可通过所CPE读取插接到CPE接口中的外部设备7存储的数据(比如，图片、文字、视频等)，或者，向所述外部设备7中写入数据。在另一种情况下，所述外部设备7可存储一些数据，相较于数据被存储在云服务器中而言，数据存储在外部设备7可提升数据的安全性。CPE是一种无线宽带接入的用户终端设备。CPE通常将基站发送的网络信号转换为无线保真技术(Wireless Fidelity，WIFI)信号。由于CPE可接收的网络信号为无线网络信号，能够节省铺设有线网络的费用。因此，CPE可大量应用于农村、城镇、医院、工厂、小区等未铺设有线网络的场合。
请参阅图22，图22为本申请一实施方式提供的用户终端设备的应用环境示意图。所述用户终端设备1a与基站3进行通信，接收基站3发出的第一网络信号，并将第一网络信号转换为第二网络信号。所述第二网络信号可供平板电脑、智能手机、笔记本电脑等终端设备5使用。其中，所述第一网络信号可以为但不限于为第五代移动通信技术(5th generation mobile networks，5G)信号，所述第二网络信号可以为但不仅限于为无线保真技术(Wireless Fidelity，WIFI)信号。CPE可大量应用于农村、城镇、医院、工厂、小区等，CPE可接入的第一网络信号可以为无线网络信号，能够节省铺设有线网络的费用。
请一并参阅图23、图24及图25。图23为本申请一实施方式提供的用户终端设备的立体示意图；图24为本申请一实施方式提供的用户终端设备去掉壳体之后的示意图；图25为本申请一实施方式提供的用户终端设备的电路框图。所述用户终端设备1a包括外壳110，所述外壳110的形状可以但不仅限于为多面柱状筒，或者是圆柱筒。所述外壳110的材料可以为但不仅限于为塑料等绝缘材料。所述USB接口20可设置在所述外壳110上。
所述用户终端设备1a包括第一天线120及信号转换器130。所述第一天线120及所述信号转换器130收容于所述外壳110之内。所述第一天线120用于接收第一网络信号，所述信号转换器130用于将所述第一天线120接收的第一网络信号转换为第二网络信号。在一种实施方式中，所述第一天线120可旋转以从不同方向接收第一网络信号。所述信号转换器130将所述第一天线120从不同方向接收到第一网络信号中信号最强的第一网络信号转换成第二网络信号。
所述第一天线120可以为但不仅限于为毫米波信号天线或者太赫兹信号天线。相应地，所述第一网络信号可以为但不仅限于为毫米波信号或者太赫兹信号。目前，在第五代移动通信技术(5th generation wireless systems，5G)中，根据3GPP TS 38.101协议的规定，5G新空口(new radio，NR)主要使用两段 频率：FR1频段和FR2频段。其中，FR1频段的频率范围是450MHz～6GHz，又叫sub-6GHz频段；FR2频段的频率范围是24.25GHz～52.6GHz，属于毫米波(mm Wave)频段。3GPP Release 15版本规范了目前5G毫米波频段包括：n257(26.5～29.5GHz),n258(24.25～27.5GHz),n261(27.5～28.35GHz)和n260(37～40GHz)。毫米波或者太赫兹信号具有传输速度快等优点，然，毫米波或者太赫兹信号容易被外界物体遮挡。当第一天线120与基站3之间有物体遮挡时，则所述第一天线120接收到的第一网络信号的信号强度较弱，此时，若将信号强度较弱的第一网络信号转换为第二网络信号，则可能导致得到的第二网络信号的信号强度也较弱。
对于放置在一定位置的用户终端设备1a而言，所述第一天线120各个方向的第一网络信号的信号强度不同。本实施方式中提供的用户终端设备1a中的所述第一天线120可旋转，当所述第一天线120位于第一网络信号的信号强度最强的方向时，所述第一天线120停留在第一网络信号的信号强度最强的方向上。所述信号转换器130将第一天线120接收的信号最强的第一网络信号转换成第二网络信号。本实施方式中的用户终端设备1a中的信号转换器130将信号最强的第一网络信号转换为第二网络信号从而保证了第二网络信号的信号强度，进而保证了利用所述第二网络信号通信时的通信质量。
在一种实施方式中，所述第一天线120可手动被旋转，或者是被驱动器170驱动而自动被旋转，只要满足所述第一天线120可被旋转即可。
请一并参阅图26及图27，图26为本申请又一实施方式提供的用户终端设备去掉壳体之后的示意图；图27为本申请又一实施方式提供的用户终端设备的电路框图。在本实施方式中，为了方便示意，去掉了所述用户终端设备1a中的所述外壳110。在本实施方式中，所述用户终端设备1a还包括多个第二天线140。所述用户终端设备1a还包括多个第二天线140。所述多个第二天线140用于接收第三网络信号，所述信号转换器130还用于将所述第三网络信号转换成第四网络信号。所述第一天线120相较于所述第二天线140设置于所述用户终端设备1a的顶部，所述多个第二天线140沿着所述用户终端设备1a的周缘分布。所述用户终端设备1a可包括但不仅限于包括8个第二天线140。可选地，两个第二天线140可组成天线组150a，且位于同于天线组150a的两个第二天线140设置在不同的基板150上。所述第二天线140及所述第一天线120工作的频段不同。在本实施方式中以一个基板150上设置两个第二天线140为例进行示意，在其他实施方式中，一个基板150上也可设置多个第二天线140。
由于发射所述第三网络信号的基站3位置的不确定性，因此，所述第三网络信号传输的方向也存在不确定性。所述多个第二天线140的位置固定，不可旋转。本申请中通过将所述第二天线140沿着所述用户终端设备1a的周缘分布，可检测到多个方向上的第三网络信号。进而可提高根据采集到的各个第三网络信号的信号强度判断信号最强的第三网络信号时的准确性。
在本实施方式中，将同一天线组150a中的多个第二天线140设置于不同的基板150上，可使得同一天线组150a中的第二天线140所能接收的第三网络信号的范围较广。换而言之，同一天线组150a中的J个第二天线140设置于不同的基板150上，使得所述同一天线组150a中的所述J个第二天线140所接收的第三网络信号的质量差异较大，当所述用户终端设备1a中的处理器控制同一个天线组150a中的多个第二天线140之间切换时，第三网络信号的质量变化较大，从而有利于通过选择同一天线组150a中不同的第二天线140快速调整所述天线组150a所接收的第三网络信号的质量，进而有利于所述用户终端设备1a工作在第三网络信号最大或者信号强度大于预设阈值的状态。
所述第二天线140可以为但不仅限于为sub-6G天线，相应地，所述第三网络信号可以为但不仅限于为sub-6G天线，所述第四网络信号可以为但不仅限于为WIFI信号。
所述多个第二天线140沿着所述用户终端设备1a的周缘分布包括但不限于所述多个第二天线140直接或间接贴附于所述外壳110上；或者，所述第二天线140设置在所述用户终端设备1a的外壳110内，且所述第二天线140不与所述外壳110接触。
在一实施方式中，所述第二天线140的数目为M个，所述信号转换器130用于根据所述第二天线140接收的第三网络信号的强度从M个第二天线140中选择N个第二天线140。当被选择的第二天线140的数目为N个时，被选择的N个第二天线140的信号强度的总和大于M个第二天线140中其余任 意N个第二天线140接收的第三网络信号的强度的总和。其中，M和N均为正整数，举例而言，M等于但不仅限于为8，N等于但不仅限于为4，当M＝8，N＝4时，J＝2。
请参阅图28，图28为本申请再一实施方式提供的用户终端设备的电路框图。所述用户终端设备还包括第三天线160，所述第三天线160用于将所述第二网络信号及所述第四网络信号发射出去。所述第三天线160可以为WIFI天线。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型，这些改进和润饰也视为本申请的保护范围。
