Patent Application
20240022025
This application relates to the field of communication technologies, and in particular to a data cable and an electronic device.
When transmitting a high-frequency signal, a connector needs a complete metal shielding housing to prevent the high-frequency signal from radiating in the form of an electromagnetic wave, and the metal shielding housing is to be grounded to achieve a best effect. A data cable is usually wrapped with copper coil, an external grounding wire is reflexed, and then the data cable is connected to an iron housing, to achieve short circuit. A Type-C connector is usually used. To prevent a port from being burnt caused by foreign matter entering the port, an open circuit structure or a short circuit through capacitor grounding is usually used.
However, in current technologies, a connection cable between a Type-A male (AM) connector and the Type C connector is to be twisted first, then tinned to prevent dispersion, and wrapped with copper foil, and a grounding wire is reflexed. After the connection cable is riveted and pressed, tin is to be added manually to ensure welding stability. This needs a lot of labor time and has high costs. To prevent short circuit between a power cable (Vbus) and the iron housing at a Type-C port, an open circuit is required for the iron housing, and an external grounding wire is to be cut off manually. This needs extra labor time and high costs. In addition, the grounding wire or weaving of the connection cable only serves grounding with an AM port, with a little loop current, and costs are to be increased.
Embodiments of this application are intended to provide a data cable and an electronic device.
According to a first aspect, an embodiment of this application provides a data cable. The data cable includes: an AM connector, a Type C connector, and a connection cable. Two ends of the connection cable are respectively electrically connected to the AM connector and the Type C connector, and the AM connector includes:
A power port pad, a signal port pad, a grounding port pad, and a conductive fastener are disposed on the rubber core, and the grounding port pad is electrically connected to an inner grounding wire of the connection cable.
The conductive fastener is connected to the grounding port pad, and the conductive fastener is in contact with the conductive housing.
According to a second aspect, an embodiment of this application further provides an electronic device. The electronic device includes an electronic device body and the foregoing data cable.
The data cable is removably connected to the electronic device body.
In this embodiment of this application, a conductive fastener is increased on an AM connector. The conductive fastener is connected to a grounding port pad on a rubber core, to achieve a grounding effect of the AM connector. The conductive fastener is in contact with a metal housing of the AM connector, to implement short circuit between the AM connector and the conductive fastener. Therefore, the external grounding wire is not to be twisted and stained with tin at an AM port, so that working time may be reduced; no copper foil is to be wrapped at the AM port, so that a material and working time may be reduced; and no tin is to be increased manually after riveting and pressing to ensure stability of AM contact, so that working time may be reduced.
The following clearly describes technical solutions in embodiments of this application with reference to accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of this application shall fall within the protection scope of this application.

It should be understood that data used in such way are interchangeable in a proper circumstance, so that the embodiments of this application can be implemented in an order other than the order illustrated or described herein. Objects classified by “first”, “second”, and the like are usually of a same type, and the number of objects is not limited. For example, there may be one or more first objects.

With reference to the accompanying drawings, the following describes in detail the data cable in the embodiments of this application based on embodiments and application scenarios for the embodiments
As shown in
A power port pad 1, signal port pads (2 is a signal D-terminal pad, and 3 is a signal D+ terminal pad), a grounding port pad 4, and a conductive fastener 5 are disposed on the rubber core 7. The grounding port pad 4 is electrically connected to an inner grounding wire of the connection cable.
The conductive fastener 5 is connected to the grounding port pad 4, and the conductive fastener 5 is in contact with the conductive housing 6.
In the embodiment of this application, a problem that the conductive housing 6 of the AM connector and an external grounding wire are grounded. By increasing the conductive fastener 5 beside the grounding port pad 4, the conductive fastener 5 is connected to the grounding port pad 4. The grounding port pad 4 is configured to weld the inner grounding wire of the connection cable. In this embodiment of this application, because the conductive fastener is connected to the grounding port pad 4, and the conductive fastener 5 is plated with weldable nickel. When the inner grounding wire is welded, the grounding port pad and the conductive fastener may be welded simultaneously. This does not increase working time. In addition, the conductive fastener 5 is further in contact with the conductive housing 6. Therefore, the conductive housing 6 and the conductive fastener 5 are short-circuited. This prevents a wire from being wrapped with copper foil, the grounding wire is to be reflexed, and tin is added for welding, reducing working time.

In this embodiment of this application, a conductive fastener is increased on an AM connector. The conductive fastener is connected to the grounding port pad to achieve a grounding effect of the AM connector. The conductive fastener is also in contact with the conductive housing, to implement short circuit between the AM connector and the conductive fastener.

In at least one embodiment of this application, because the AM connector and a part grounded at the AM connector are short-circuited, no extra external grounding wire is required to provide a loop. Therefore, the external grounding wire may be canceled. This reduces material costs for the external grounding wire. Correspondingly, as shown in
The power cables 302 are configured to provide a power supply, and the signal cables 303 are configured to transmit a USB signal. The inner grounding wires 301 are disposed between the two signal cables, and are respectively connected to the two signal cables and an inner surface of the aluminum foil.

Correspondingly, in at least one embodiment of this application, the power port pad is electrically connected to the power cable of the connection cable; and the signal port pad is electrically connected to the signal cable of the connection cable.
In this embodiment of this application, because the external grounding wire of the connection cable is canceled, working time for which the external grounding wire or twisting is to be cut off manually at the Type-C port, and material costs for the external grounding wire are reduced.

Therefore, the external grounding wire is not to be twisted and stained with tin at an AM port, so that working time may be reduced; no copper foil is to be wrapped at the AM port, so that a material and working time may be reduced; and no tin is to be increased manually after riveting and pressing to ensure stability of AM contact, so that working time may be reduced; and no external grounding wire is provided for the Type-C port, and no action for cutting off the external grounding wire is performed, so that working time may be reduced.
