Description

Technical Field

[0001] This utility model relates to the field of Type-C cables, and more specifically, to a data cable with a high-power Type-C connector. Background Technology

[0002] A 240W single-IC charging cable with two Type-C ends requires at least 6 cores to achieve 100W or 240W charging power. To reach this power, it needs to comply with the industry-standard PD protocol, necessitating the addition of an E-Mark IC for protocol identification. Therefore, the cable structure should be: "Type-C connector (with IC end) --- connecting cable --- Type-C connector (without IC end)". When the non-IC end is the receiving end (i.e., when this non-IC Type-C connector is connected to the charging device), the Type-C connector with the IC end acts as the power supply end, connecting the phone or other terminal device. In this case, a connecting cable is needed to supply power from the charging device to the E-Mark IC on the other end of the Type-C connector. Alternatively, without a separate power supply line for the IC, both Type-C connectors would need to have E-Mark ICs installed, further increasing costs. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a high-power Type-C connector data cable, comprising a first Type-C interface, a second Type-C interface, and an electronic tagging chip. The electronic tagging chip is installed inside the first Type-C interface. The first Type-C interface has a first terminal, and the second Type-C interface has a second terminal. The first and second terminals include a VBUS terminal, a D+ terminal, a D- terminal, a CC terminal, and a GND terminal arranged sequentially. The VBUS terminal, D+ terminal, D- terminal, CC terminal, and GND terminal are connected by a wire. The electronic tagging chip includes a first VCONN terminal and a second VCONN terminal. The first VCONN terminal is suspended, and the second VCONN terminal is directly connected to the VBUS terminal of the first and second terminals by a wire.

[0004] Furthermore, the electronic tag chip also includes a CC terminal and a GND terminal. The CC terminal of the electronic tag chip is connected to the CC terminals of the first terminal and the second terminal via wires, and the GND terminal of the electronic tag chip is connected to the GND terminals of the first terminal and the second terminal via wires.

[0005] Furthermore, protective resistors are provided between the VCONN terminal and the GND terminal of the first terminal, and between the VCONN terminal and the GND terminal of the second terminal.

[0006] Furthermore, the resistance of the protective resistor is 1 kiloohm.

[0007] Furthermore, both the first terminal and the second terminal include a plug-in terminal and a PCB board, and the electronic tag chip is disposed on the PCB board of the first terminal.

[0008] Furthermore, the VBUS, D+, D-, CC, and GND terminals of the first and second terminals are all located on the plug-in terminals.

[0009] Furthermore, the electronic tagging chip is one of the following models: CYPD2103, CYPD4225, PTN3600, or PS8825.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This application incorporates an electronic tag chip inside the first Type-C interface, allowing the second VCONN terminal of the electronic tag chip to be directly connected to the VBUS terminals of the first and second terminals via a wire. This enables the present invention to achieve interconnection and adjustment of the interfaces using only one electronic tag chip and a five-core wire. This not only maintains the charging voltage of the present invention at 100W or 240W, but also saves the cost of an electronic tag chip and reduces the number of power supply lines, thereby lowering production costs.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings, such as... Figure 1 As shown, a high-power Type-C connector data cable includes a first Type-C interface 1, a second Type-C interface 2, and an electronic tag chip 3. The electronic tag chip 3 is installed inside the first Type-C interface 1. The first Type-C interface 1 has a first terminal inside, and the second Type-C interface 2 has a second terminal inside. The first terminal and the second terminal include a VBUS terminal, a D+ terminal, a D- terminal, a CC terminal, and a GND terminal arranged sequentially. The VBUS terminal, D+ terminal, D- terminal, CC terminal, and GND terminal are connected by a wire 4. The electronic tag chip 3 includes a first VCONN terminal and a second VCONN terminal. The first VCONN terminal is suspended, and the second VCONN terminal is directly connected to the VBUS terminal of the first terminal and the second terminal through the wire 4.

[0023] In the operating state of this application, the first Type-C interface 1 and the second Type-C interface 2 are located at opposite ends of the wire 4. The second Type-C interface 2 is the power receiving end, i.e., connected to a charging device (e.g., a charging plug or power bank). The first Type-C interface 1 serves as the power supply end, connecting to terminal devices such as mobile phones. The electronic tag chip 3 is located inside the first Type-C interface 1, and its second VCONN terminal is connected to the VBUS terminals of the first and second terminals respectively via the wire 4.

[0024] Compared with the prior art, this application sets an electronic tag chip 3 inside the first Type-C interface 1, and allows the second VCONN terminal of the electronic tag chip 3 to be directly connected to the VBUS terminals of the first and second terminals through the wire 4. This allows the present invention to achieve the connection and adjustment of the interface with only one electronic tag chip 3 and five-core wire 4. This not only keeps the charging voltage of the present invention at 100W or 240W, but also saves the cost of one electronic tag chip 3, and reduces the number of power supply lines, thereby reducing the production cost.

[0025] Furthermore, based on the above embodiments, such as Figure 1 As shown, the electronic tag chip 3 also includes a CC terminal and a GND terminal. The CC terminal of the electronic tag chip 3 is connected to the CC terminals of the first terminal and the second terminal via a wire 4. The GND terminal of the electronic tag chip 3 is connected to the GND terminals of the first terminal and the second terminal via a wire 4.

[0026] Furthermore, based on the above embodiments, such as Figure 1As shown, protective resistors are provided between the VCONN terminal and the GND terminal of the first terminal and between the VCONN terminal and the GND terminal of the second terminal. Since VCONN is directly connected to the power supply (usually 5V), the short-circuit current can be limited by setting the protective resistor to avoid overload or burnout of the power chip, as well as short circuit between VCONN and GND due to abnormal insertion or removal or physical damage.

[0027] Furthermore, based on the above embodiments, such as Figure 1 As shown, the resistance of the protection resistor is 1 kΩ. When the present application is working normally, the voltage drop of the 1 kΩ resistor is lower (for example, if the operating current of the electronic marker chip 3 is 1 mA, the voltage drop is only 1 V), which can ensure that the VCONN voltage is closer to 5 V, improve the power supply stability of the electronic marker chip 3, and is especially suitable for long cables or high impedance scenarios.

[0028] Furthermore, based on the above embodiments, such as Figure 2 As shown, both the first terminal and the second terminal include a plug-in terminal 5 and a PCB board 6. The electronic tag chip 3 is disposed on the PCB board 6 of the first terminal. In this way, compared with the prior art, this application only needs to use one electronic tag chip 3 to realize the connection and adjustment of the interface between them, which not only keeps the charging voltage of this utility model at 100W or 240W.

[0029] Furthermore, based on the above embodiments, such as Figure 2 As shown, the VBUS, D+, D-, CC, and GND terminals of the first and second terminals are all located on the plug-in terminal 5. Preferably, the electronic tag chip 3 is one of CYPD2103, CYPD4225, PTN3600, or PS8825. All of these models can ensure that the VCONN voltage is closer to 5V when the resistance of the protection resistor is 1 kΩ.

[0030] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
