技术领域
本发明实施例涉及无线通讯技术领域, 尤其涉及一种无线终端设备。 背景技术

具体实施方式
下面结合附图和具体实施例进一步说明本发明实施例的技术方案。
根据本发明的实施例, 提供了一种无线终端设备, 包括导接模块、 与导 接模块连接的第一 PCB、 以及第一导体。 在本发明实施例的无线终端设备中, 导接模块和第一 PCB其中之一通过第一电容耦合模块与第一导体的一端连 接, 导接模块和第一 PCB其中之另一与第一导体的另一端连接。 也就是说, 包括两种情况:
情况一, 导接模块通过第一电容耦合模块与第一导体的一端连接, 第一 PCB与第一导体的另一端连接;
情况二, 第一 PCB通过第一电容耦合模块与第一导体的一端连接, 导接 模块与第一导体的另一端连接。

此外, 在本发明实施例中, 第一电容耦合模块可以为: 第一绝缘材料介 质或第一集总电容元器件; 第二电容耦合模块可以为: 第二绝缘材料介质或 第二集总电容元器件。
下面, 结合附图,分别对上述各种情况下的无线终端设备进行详细说明。 图 2是本发明实施例一的无线终端设备的示意图, 如图 2所示, 根据本 发明实施例的无线终端设备包括: 导接模块、 第一导体 22。 需要说明的是, 本发明实施例的无线终端设备可以为手机或无线网卡。 在该无线终端为手机 时, 导接模块可以为第二 PCB; 在该无线终端为无线网卡时, 导接模块可以 为 USB转接头 20。 优选地, 在本实施例中 , 以导接模块为 USB转接头 20为 例对本发明实施例的技术方案进行说明。
具体地, USB转接头 20中设置有电源线 Vdd、 地线 GDN与差分信号 线 D+/-, 其中差分信号线包括正差分信号线 D+和负差分信号线 D-, USB转 接头 20中的上述四根信号线分别与第一 PCB 24上的电源线 Vdd、地线 GDN 与差分信号线 D+/-对应连接, 即, USB转接头 20中的电源线 Vdd连接至第 一 PCB24上的电源线 Vdd, USB转接头 20中的地线 GDN连接至第一 PCB24 上的地线 GDN, USB转接头中的正差分信号线 D+连接第一 PCB24上的正差 分信号线 D+, USB转接头 20中的负差分信号线 D-连接至第一 PCB24上的 负差分信号线 D-, 形成导线体。 其中, 该导线体可以分别使用绝缘材料进行 包裹, 在使用绝缘材料进行包裹后, 在上述导线体外面再套设一个用于屏蔽 和接地的金属导电层,该金属导电层两端分别与 USB转接头 20和第一 PCB 24 连接, 达到将导线体屏蔽接地的目的; 上述方式可以通过 USB线结构和柔性 电路板 ( Flexible Printed Circuit; 以下简称: FPC )结构实现。
如图 2所示, 本发明实施例的转接装置包括第一导体 22, 该第一导体 22 的一端与 USB转接头 20通过第一绝缘材料介质 26连接, 进一步地, 在第一 导体 22的一端与 USB转接头 20外侧的金属层设置第一绝缘材料介质 26。由 于第一导体 22的一端与 USB转接头 20不直接连接, 因此, 上述方式的连接 也称为虚接。 这样, 可以使得第一导体 22的与 USB转接头 20的虚接处能够 形成电容器的结构。 此外, 该第一绝缘材料介质 26还起到了将第一导体 22 固定在 USB转接头 20上的作用。 在实际应用中, 还可以使用第一集总电容 元器件代替上述第一绝缘材料介质 26, 使用第一集总电容元器件也可以同使 用第一绝缘材料介质 26达到同样的效果, 即, 形成电容耦合效应。 在本发明 实施例中, 上述第一导体 22可以为金属弹片, 如图 2所示, 金属弹片两端有 两个弹脚, 分别是第一弹脚 220和第二弹脚 222, 其中第一弹脚 220与 USB 转接头 20虚接。 第一导体 22的另一端设置有用于与第一 PCB24连接的第二 绝缘材料介质 28, 也就是说,金属弹片的第二弹脚 222与第一 PCB24上电路 板间的空地通过第二绝缘材料介质 28虚接。 从而使得金属弹片的第二弹脚 222与第一 PCB24的虚接处形成了电容器结构, 实现第一 PCB24与第一导体 22的电容耦合效应。 在实际应用中, 还可以使用第二集总电容元器件代替上 述第二绝缘材料介质 28, 也可以同使用第二绝缘材料介质 28达到同样的效 果。
通过上述处理, 与双接地的旋转式 USB转接头方式相比, 本发明实施例 的无线终端设备通过电容耦合的方式将 USB转接头与第一 PCB24连接, 避 免了第一导体 22与 USB转接头 20、 以及第一 PCB24压接不充分, 导致阻抗 变大的问题。
同时, 采用上述方式可以改变现有技术中采用旋转式 USB方式对工艺要 求比较高、 不易实现的缺陷, 由于本发明实施例中的第一导体与 USB转接头 或 PCB通过绝缘介质进行连接, 即, 虚接, 并在虚接处形成电容, 通过电容 耦合的方式将 USB转接头与 PCB连接, 避免了对接地导线与无线网卡 PCB 的接触点上的电阻的控制, 从而易于生产, 提高了产品的合格率。 此外, 由 于本发明实施例采用了电容耦合的方式将 USB转接头与 PCB连接, 在一定 程度上对双接地旋转式 USB 转接头方式中的电磁波吸收比值 (Specific Absorption Rate; 以下简称: SAR )有所改善。

通过上述处理, 与双接地的旋转式 USB转接头方式相比, 本发明实施例 的无线终端设备一端通过电容耦合的方式连接 USB转接头, 另一端直接连接 PCB, 由于一端采用电容耦合的方式连接 USB 转接头, 避免了第一导体 32 与 USB转接头 30、 以及第一 PCB34压接不充分, 导致阻抗变大的问题。
同时, 本发明实施例的无线终端设备一端通过电容耦合的方式连接 USB 转接头 , 避免了对接地导线与无线网卡 PCB的接触点上的电阻的控制 , 从而 易于生产, 提高了产品的合格率。
根据本发明的实施例, 提供了一种无线终端设备, 图 4是本发明实施例 三的无线终端设备的示意图, 如图 4所示, 根据本发明实施例的转接装置包 括: 导接模块、 第一导体 42。 优选地, 需要说明的是, 本发明实施例的无线 终端设备可以为手机或无线网卡。 在该无线终端为手机时, 导接模块可以为 第二 PCB; 在该无线终端为无线网卡时, 导接模块可以为 USB转接头 40。 优选地, 在本实施例中, 以导接模块为 USB转接头 40为例对本发明实施例 的技术方案进行说明。 具体地, USB转接头 40中设置有电源线 Vdd、 地线 GDN与差分信号 线 D+/-, 其中差分信号线包括正差分信号线 D+和负差分信号线 D-, USB转 接头 40中的上述四根信号线分别与无线终端设备中第一 PCB44上的电源线 Vdd、 地线 GDN与差分信号线 D+/-对应连接, 形成导线体。 其中, 该导线体 还需要分别使用绝缘材料进行包裹, 在使用绝缘材料进行包裹后, 在上述导 线体外面再套设一个用于屏蔽和接地的金属导电层, 该金属导电层两端分别 与 USB转接头 40和第一 PCB 44连接, 达到将导线体屏蔽接地的目的; 在实 际应用中 , 上述方式可以通过 USB线结构和 FPC结构实现。
如图 4所示, 本发明实施例的转接装置中包括第一导体 42, 该第一导体 42的一端与 USB转接头 40直接连接。 在本发明实施例中, 上述第一导体 42 可以为金属弹片, 如图 4所示, 金属弹片两端有两个弹脚, 分别是第一弹脚 420和第二弹脚 422, 其中第一弹脚 420与 USB转接头 40直接连接, 第一导 体 42的第二弹脚 422与第一 PCB44通过第二绝缘材料介质 46连接, 即, 第 一导体 42的另一端与第一 PCB44虚接。在第一导体 42与第一 PCB44的虚接 处, 需要填充第二绝缘材料介质 46, 从而使得第一导体 42的与第一 PCB44 的虚接处能够形成电容器的结构。 此外, 该第二绝缘材料介质 46还起到了将 第一导体 42固定在第一 PCB44上的作用。 在实际应用中, 还可以使用第二 集总电容元器件代替上述第二绝缘材料介质 46, 也可以同使用第二绝缘材料 介质 46达到同样的效果。
通过上述处理与双接地的旋转式 USB转接头方式相比, 本发明实施例的 无线终端设备一端通过电容耦合的方式连接 USB 转接头, 另一端直接连接 PCB, 由于一端采用电容耦合的方式连接 USB 转接头, 避免了第一导体 42 与 USB转接头 40、 以及第一 PCB44压接不充分, 导致阻抗变大的问题。
同时, 本发明实施例的无线终端设备一端通过电容耦合的方式连接 USB 转接头 40, 另一端直接连接 PCB, 由于一端采用电容耦合的方式连接 USB 转接头 40, 避免了对接地导线与无线网卡 PCB的接触点上的电阻的控制, 从 而易于生产, 提高了产品的合格率。
