一种数据线 技术领域
本发明涉及电子产品配件领域，尤其是涉及一种数据线。
 背景技术
随着USB C技术不断的发展和完善，USB C接口已经被广泛的应用于电子设备之间。新一代的传输速率为5 Gbps （第一代）或10 Gbps（第二代） 的 USB C对USB C的数据线已经成为电子设备的标准配线了，该种USB C对USB C的数据线包括线缆以及分别连接到线缆两端的两个USB C连接器（例如公连接器）。但是，目前还有数量庞大的电子设备只具有USB 3.0 A型母座或USB 3.0 Micro B型母座。因此，用户需要USB 3.0 A或USB 3.0 Micro B对USB C的数据线，该种USB 3.0 A或USB 3.0 Micro B对USB C的数据线包括线缆以及分别连接到线缆两端的USB 3.0 A连接器（例如USB 3.0 A公连接器）或USB 3.0 Micro B（例如USB 3.0 Micro B公连接器）和USB C连接器（例如USB C公连接器）。因此，用户需要USB C对USB C的数据线、USB 3.0 A或USB 3.0 Micro B对USB C的数据线才能满足日常使用。
目前出现了一种USB C 母转换器，该转换器的两端分别具有USB 3.0 A公连接器或USB 3.0 Micro B公连接器和USB C母连接器，如此，USB C对USB C的数据线的USB C公连接器插入到USB C母连接器之后，就形成了USB 3.0 A或USB 3.0 Micro B对USB C的数据线。该种转换器满足了用户的日常使用。但是，USB C公连接器是可以正反插的（即，旋转180度之后也能插入USB C母连接器），而USB 3.0 A或USB 3.0 Micro B公连接器不能正反插，因此，需要在USB 3.0 A或USB 3.0 Micro B对USB C的转换器里面设置检测与切换电路，该检测与切换电路用于检测USB C公连接器是正面插入还是反面插入，并根据检测结果进行相应的电路切换以保障USB 3.0 A或USB 3.0 Micro B对USB C的转换。该检测与切换电路导致响应时间的延迟和能量的损失，使得高频信号产生一定的畸变，信号传输速率降低。此外，该检测与切换电路增加了USB 3.0 A或USB 3.0 Micro B对USB C母转换器的成本、并降低了成品率。
此外，USB C对USB C的数据线会存在电子标签（e-marker）电路，电子标签电路用于产生USB C的配置通道（CC, configuration channel）信号。上述转换器连接USB C对 C数据线使用时，若用户先连接USB C型电子设备后连接USB 3.0 A型或USB 3.0 Micro B型电子设备，该配置通道信号很可能会干预到USB 3.0 A型或USB 3.0 Micro B型电子设备，导致USB枚举出现异常，即，可能会导致该种USB C 母转换器连接USB C对 C数据线不能正常使用。用户需要先连接USB 3.0 A型或USB 3.0 Micro B型电子设备后连接USB C型电子设备才能正常使用。

 本发明的实施方式
下面结合附图和实施例对本发明作进一步的描述。
第一实施例
参考图1和图2，本发明提供的一种数据线，包括数据线本体和第一转换器40。数据线本体包括线缆10、连接在线缆10第一端的第一连接器20以及连接在线缆10第二端的第四连接器30。第一连接器20包括连接到线缆10第一端的第一壳体21以及设置在第一壳体21的远离线缆10的第一端的第一接头22。第四连接器30包括连接到线缆10第二端的第四壳体31以及设置在第四壳体31的远离线缆10的第二端的第四接头32。第一转换器40包括通信连接的第二连接器42和第三连接器43。第一连接器20和第二连接器42的形状允许第二连接器42以正面方向、反面方向均能插接到第一连接器20的第一接头22。第三连接器43为只能单面插接的连接器。
第一转换器40通过第一柔性连接件50连接到第一连接器20的右侧，从而与数据线本体连接成一个整体，方便携带。第一柔性连接件50与第一连接器20的连接处偏离第一连接器20的第一接头22和第一柔性连接件50与第一转换器40的连接处靠近第二连接器42，当第二连接器42位于正面方向时，第二连接器42能够插接到第一接头22，当第二连接器42位于反面方向时，第一柔性连接件50被扭转，被扭转后的第一柔性连接件50长度缩短从而使第二连接器42不能够插接到第一接头22，如此则保证了第二连接器42只能以正向插接到第一连接器20的第一接头22，保障了数据线的正常工作，且相对传统的USB C 母转换器连接USB C to C数据线，由于没有设置电子开关（检测与切换电路），从而大大提高了数据线信号的传输速率，信号传输速率可提高20%，同时大大降低了成本。
在其他实施方式中，第一柔性连接件50与第一连接器20的连接处偏离第一连接器20的第一接头22或者第一柔性连接件50与第一转换器40的连接处靠近第二连接器42，只要满足其中一个条件，同样可保证第二连接器42只能以正向插接到第一连接器20的第一接头22。
上述的结构设计，均有利于提醒用户是第二连接器42插接到第一连接器20。
本实施例中，第一转换器40还包括第一转换器壳体41，第二连接器42和第三连接器43分别设置在第一转换器壳体41的两端。第一柔性连接件50连接在第一转换器壳体41和第一连接器20的第一壳体21之间。
在实际应用时，可将第四接头32插入到一种电子设备的与第四接头32相匹配的接口中，将第二连接器42插接到第一接头22，再将第三连接器43插入到另一种电子设备的与第三连接器43相匹配的接口中，如此，即可实现两种不同接口的电子设备之间的数据传输。两种不同接口的电子设备，例如手机和电脑或平板电脑，电脑或平板电脑。
本实施例中，第一连接器20和第四连接器30都是USB C公连接器。第二连接器42为USB C母连接器。第三连接器43为USB A公连接器，优选地，第三连接器43优选为USB3.0A公连接器。 进一步优选地，USB C母连接器为一USB C母接口，USB3.0A公连接器为一USB3.0A公接头。如此，本发明的数据线可实现带USB C接口的电子设备与带USB3.0A接口的电子设备之间的数据传输，例如带USB C接口的手机与带USB3.0A接口的电脑或平板电脑之间的数据传输。本发明的数据线本体可实现的传输速率为5Gbps（交换带宽，第一代）或10Gbps（交换带宽，第二代）。
在其他实施方式中，第一连接器20可以为USB C连接器，第四连接器30可以为USB2.0A连接器或Mini USB连接器或Micro USB连接器，第二连接器42为USB C母连接器。第三连接器43为USB A公连接器，如此，可实现带USB2.0A接口或Mini USB接口或Micro USB接口的电子设备与带USB 3.0A接口的电子设备之间的数据传输。
结合图3所示，USB C母接口包括Pin 脚如A1-A12以及B1-B12，共24个。结合图4所示，USB3.0A公接头包括Pin 脚如1-9，共9个。
结合图5所示，本实施例中，第一连接器20和第四连接器30都是USB C公连接器，第三连接器43为USB A公连接器。该种结构下，数据线本体为USB C公对USB C公的数据线。本领域技术人员可知晓，USB C公对USB C公的数据线会设置有电子标签（e-marker）电路，电子标签电路用于产生USB C的配置通道（CC, configuration channel）信号。当转换器连接到数据线本体时，该数据线相当于USB C公对USB A公的数据线。如用户先将USB C公连接到设备再将USB A公连接器连接到设备，此时，电子标签电路产生的配置通道信号很可能会影响到USB A公连接器，从而影响或阻碍USB A公连接器的枚举过程，导致数据线无法成功连接。
为解决该问题，本实施例中，第一转换器40设有高频滤波电路，用于过滤第一连接器20的CC（configuration channel ，配置通道）Pin脚传输过来的无用的高频干扰信号（即配置通道信号）。高频滤波电路优选设置在第一转换器壳体41内。高频滤波电路包括旁路电容C1，旁路电容C1的第一极与第二连接器42的Pin 脚A5电连接，旁路电容C1的第二极接地。旁路电容C1的容量优选为1微发（uF）。第一极通过第一电阻R1串联到第三连接器43的Pin 脚1。第一电阻R1的阻值优选为56K（K=千）欧姆。第二连接器42的Pin 脚A4、B4、A9、B9与第三连接器43的Pin 脚1并联。第二连接器42的Pin 脚A1、B1、A12、B12并联在第三连接器43的Pin 脚4、7并联。第二连接器42的Pin 脚A6、A7、A2、A3、B11、B10分别与第三连接器43的Pin 脚3、2、9、8、6、5串联。
本实施例中，第一转换器壳体41、第一壳体21和第一柔性连接件50为一体成型，便于制造。可以理解地，第一转换器壳体41、第一壳体21和第一柔性连接件50也可以是分体成型。
本实施例中，第一柔性连接件50的截面形状为非圆形，辟如矩形、方形。
第一柔性连接件50为PVC连接绳或硅胶连接绳，便于弯曲，以便第二连接器42能够插接到第一连接器20的第一接头22。第一转换器壳体41和第一壳体21均为PVC壳体或硅胶壳体。可以理解地，第一柔性连接件50、第一转换器壳体41、第一壳体21也可以是其他的柔性材料。
第二连接器30的第二壳体31的一侧设有连接环33。连接环33的设置，便于挂接到其他物品上，方便携带或放置。
第二实施例
参考图6和图7，本实施例与第一实施例不同的是，第一转换器40通过第一柔性连接件50连接到第一连接器20的左侧，从而与数据线本体连接成一个整体。

进一步优选地，USB C母连接器为一USB C母接口，USB3.0 Micro B公连接器为一USB3.0 Micro B公接头。如此，本发明的数据线可实现带USB C接口的电子设备与带USB3.0 Micro B接口的电子设备之间的数据传输，例如带USB3.0 Micro B 接口的设备与带USB C接口的电脑或平板电脑之间的数据传输。
结合图8所示，第三连接器43为USB3.0 Micro B公接头，包括Pin脚如1-9，共9个。
结合图9所示，本实施例的高频滤波电路包括旁路电容C2，旁路电容C2的第一极与第二连接器42的Pin脚A5电连接，且旁路电容C2的第二极通过第二电阻R2接地。旁路电容C2的容量优选为1微发（uF）。第二电阻R2的阻值优选为5.1K（K=千）欧姆。第二连接器42的Pin脚A4、B4、A9、B9与第三连接器43的Pin脚1并联。第二连接器42的Pin脚A1、B1、A12、B12与第三连接器43的Pin脚5并联，第三连接器43的Pin脚8和第三连接器43的铁壳并联。第二连接器42的Pin脚A6、A7、A2、A3、B11、B10分别与第三连接器43的Pin脚3、2、7、6、10、9串联。
第三实施例
参考图10，本实施例与第一实施例不同的是，数据线还包括第二转换器60，第二转换器60包括通信连接的第五连接器62和第六连接器63。第四连接器30和第五连接器62的形状允许第五连接器62以正面方向、反面方向均能插接到第四连接器30的第四接头32。第一转换器40与第一连接器20组合，第二转换器60与第四连接器30组合，本发明的数据线可实现5 Gbps （第一代）的传输速率，也可实现10 Gbps（第二代）的传输速率。
第二转换器60通过第二柔性连接件70连接到第四连接器30的右侧。第二柔性连接件70与第四连接器30的连接处偏离第四连接器30的第四接头32和第二柔性连接件70与第二转换器60的连接处靠近第五连接器62，当第五连接器62位于正面方向时，第五连接器62能够插接到第四接头32，当第五连接器62位于反面方向时，第二柔性连接件70被扭转，被扭转后的第二柔性连接件70长度缩短从而使第五连接器62不能够插接到第四接头32，如此则保证了第五连接器62只能以正向插接到第四连接器30的第四接头22，保障了数据线的正常工作。
在其他实施方式中，第二柔性连接件70与第四连接器30的连接处偏离第四连接器30的第四接头32或者第二柔性连接件70与第二转换器60的连接处靠近第五连接器62，只要满足其中一个条件，同样可保证第五连接器62只能以正向插接到第四连接器30的第四接头32。
上述的结构设计，均有利于提醒用户是第五连接器62插接到第四连接器30。
本实施例中，第二转换器60还包括第二转换器壳体61，第五连接器62和第六连接器63分别设置在第二转换器壳体61的两端。第二柔性连接件70连接在第二转换器壳体61和第四连接器30的第四壳体31之间。
本实施例中，第二转换器壳体61、第四壳体31和第二柔性连接件70为一体成型，便于制造。可以理解地，第二转换器壳体61、第四壳体31和第二柔性连接件70也可以是分体成型。

第一柔性连接件50、第二柔性连接件70的截面形状为非圆形，例如矩形、方形。
第二连接器30的第二壳体31的一侧没有设置连接环。
本实施例中，第一连接器20和第四连接器30都是USB C公连接器。第二连接器42、第五连接器62为USB C母连接器。第三连接器43为USB A公连接器，优选地，第三连接器43优选为USB3.0A公连接器。第六连接器63为USB Micro B公连接器，优选地，第六连接器63优选为USB3.0 Micro B公连接器。
进一步优选地，USB C母连接器为一USB C母接口，USB3.0A公连接器、USB3.0 Micro B公连接器分别为一USB3.0A公接头、USB3.0 Micro B公接头。
如此，本发明在实际应用时，可实现带USB C接口的电子设备与带USB3.0A接口的电子设备之间的数据传输，也可实现带USB C接口的电子设备与带USB3.0 Micro B接口的电子设备之间的数据传输，另外，第一转换器40插接到第一连接器20后等效为USB 3.0 A公头，第二转换器60插接到第四连接器30后等效为USB 3.0 Micro B公头，在该情形下，本发明的数据线相当于一条USB 3.0 A对USB 3.0 Micro B数据线，从而可实现带USB3.0A接口的电子设备与带USB3.0 Micro B接口的电子设备之间的数据传输。本发明的数据线可实现5Gbps或10Gbps的传输速率，具体选用何种组合的接头，可根据实际情况进行选择，从而可实现多种功能。

以上实施例仅表达了本发明的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，如对各个实施例中的不同特征进行组合等，这些都属于本发明的保护范围。
