Description

Technical Field

[0001] The utility model relates to the field of electronic device interface testing, and particularly relates to an adapter tool for debugging a Type-C signal interface. Background Technique

[0002] With the rapid development of electronic devices, the Type-C interface has become one of the mainstream interfaces in the market due to its versatility and convenience. The Type-C interface not only supports high-speed data transmission but also has multiple functions such as charging and video output. However, these advantages also bring new challenges to the development and debugging process.

[0003] In practical applications, especially in the development and testing stage, it is necessary to perform simulation operations on each pin of the Type-C interface to verify the stability and reliability of the device under abnormal conditions. The existing debugging methods have the following problems:

[0004] First of all, traditional debugging methods often require technicians to directly perform soldering operations on the USB conversion board. This manual operation lacks unified specifications, and there are significant differences in the soldering methods and levels of different personnel, which is likely to cause inconsistent operations and large errors in test results.

[0005] Secondly, during the process of manually soldering the circuit, due to the lack of standardized operations, complex and messy connections may occur on the circuit board. Such connection methods not only affect the stability of the circuit but also may cause electrical interference, making the test results unreliable.

[0006] Furthermore, due to the complexity and randomness of manual soldering, the probability of making mistakes during the operation is relatively high. Once a problem occurs, it becomes very difficult to locate and repair the fault. At the same time, since each soldering operation may be slightly different, the test results are difficult to reproduce, reducing the repeatability and accuracy of the test.

[0007] In addition, the Type-C interface integrates multiple functions such as power delivery (PD), high-speed data transmission (such as USB 3.1), and video output (such as DisplayPort), which requires precise control of each pin during the debugging process. It is very difficult to perform operations such as floating, open circuit, or short circuit on these pins flexibly with traditional soldering methods, and it is difficult to meet complex test requirements.

[0008] Finally, there is a lack of dedicated tools for debugging the Type-C interface in the current market. Existing adapter devices often have single functions and cannot meet the flexible control requirements of developers for multiple pins. This results in low efficiency in the debugging process of the Type-C interface and makes it difficult to comprehensively verify the performance and reliability of the device.

[0009] Therefore, there is an urgent need to invent a conversion tool for debugging Type-C signal interfaces to effectively solve at least one of the above problems. Summary of the Utility Model

[0010] The purpose of the present utility model is to provide a conversion tool for debugging Type-C signal interfaces to solve the problems of complex and non-standard debugging operations and lack of dedicated tools in the prior art for Type-C interfaces.

[0011] To achieve the above object, the technical solution adopted by the present utility model is: a conversion tool for debugging Type-C signal interfaces, including a Type-C male head, a Type-C female head, a circuit connection board, multiple groups of first pin groups, multiple groups of second pin groups, and multiple detachable connectors. The circuit connection board is electrically connected between the Type-C male head and the Type-C female head. The multiple groups of first pin groups and multiple groups of second pin groups are both arranged on the circuit connection board, and the multiple groups of first pin groups and multiple groups of second pin groups are disconnected and arranged opposite to each other; the first pin group is electrically connected to the corresponding pins of the Type-C male head; the second pin group is electrically connected to the corresponding pins of the Type-C female head. The multiple detachable connectors are used to selectively connect or disconnect the corresponding pin pairs in the first pin group and the second pin group.

[0012] Further, each of the multiple groups of first pin groups and second pin groups includes at least 24 pins, corresponding to the 24 standard pins of the Type-C interface.

[0013] Further, the conversion tool further includes multiple pin headers, and the pin headers are respectively arranged on the multiple groups of first pin groups and multiple groups of second pin groups.

[0014] Specifically, the detachable connector is a shorting cap, and the shorting cap is used to connect the pin headers.

[0015] Further, the shorting cap connects two adjacent pin headers.

[0016] More specifically, both the first pin group and the second pin group are provided with an upper row group and a lower row group. The upper row group is arranged on the upper surface of the first pin group and the second pin group, and the lower row group is arranged on the lower surface of the first pin group and the second pin group.

[0017] Further, both the upper row group and the lower row group include 12 pins.

[0018] The present utility model further includes wires or pull-down resistors arranged between the first pin group and the Type-C male head and between the second pin group and the Type-C female head.

[0019] Specifically, the default state of the first pin group and the second pin group is to be electrically connected through the detachable connection member.

[0020] The utility model further includes one or more indicator lights for indicating the connection states of the multiple groups of first pin groups and the multiple groups of second pin groups.

[0021] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0022] The utility model provides an adapter tool for debugging a Type-C signal interface. The circuit connection board is electrically connected between the Type-C male head and the Type-C female head.

[0030] Next, a more detailed description will be given of an adapter tool for Type-C signal interface debugging according to the present utility model with reference to the accompanying drawings, in which the preferred embodiments of the present utility model are shown. It should be understood that those skilled in the art can modify the present utility model described herein while still achieving the advantageous effects of the present utility model. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present utility model.

[0031] In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the accompanying drawings. The advantages and features of the present utility model will be clearer according to the following description. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model.

[0032] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0033] In this embodiment, as Figures 1 to 3 shown, an adapter tool for Type-C signal interface debugging includes a Type-C male head 1, a Type-C female head 2, a circuit connection board 3, multiple groups of first pin groups 41, multiple groups of second pin groups 42, and multiple detachable connection members 5. The circuit connection board 3 is electrically connected between the Type-C male head 1 and the Type-C female head 2. Multiple groups of first pin groups 41 and multiple groups of second pin groups 42 are both arranged on the circuit connection board 3, and the multiple groups of first pin groups 41 and multiple groups of second pin groups 42 are disconnected and arranged opposite to each other; the first pin group 41 is electrically connected to the corresponding pins of the Type-C male head 1; the second pin group 42 is electrically connected to the corresponding pins of the Type-C female head 2. The multiple detachable connection members 5 are used to selectively connect or disconnect the corresponding pin pairs in the multiple groups of first pin groups 41 and second pin groups 42. This structural design enables the present adapter tool to flexibly control each pin of the Type-C interface, facilitating various debugging operations.

[0034] Furthermore, the adapter tool further includes a plurality of pin headers 6, the pin headers 6 are arranged on the multiple groups of first pin groups 41 and multiple groups of second pin groups 42, and the pin headers 6 are respectively arranged on the multiple groups of first pin groups 41 and multiple groups of second pin groups 42. A plurality of the detachable connectors 5 are used to connect the pin headers 6.

[0035] Preferably, both the first pin group 41 and the second pin group 42 include at least 24 pins, corresponding to the 24 standard pins of the Type-C interface. Such a design ensures that this adapter tool can fully cover all the standard pins of the Type-C interface and provide comprehensive debugging capabilities.

[0036] In a specific embodiment, as Figure 4 described, these 24 pins include 4 ground (GND) pins, 4 bus power (VBUS) pins, 2 USB 2.0 differential pairs (D+ and D-), 4 USB 3.2 SuperSpeed differential pairs (TX1±, TX2±, RX1±, RX2±), 2 configuration channel (CC1 and CC2) pins, and 2 sideband use (SBU1 and SBU2) pins. This configuration enables this adapter tool to support all the standard functions of the Type-C interface, including USB 2.0 and USB 3.2 data transmission, power transmission, and various alternate modes.

[0037] In this embodiment, the detachable connector 5 is a shorting cap. The use of the shorting cap enables the operator to conveniently connect or disconnect specific pin pairs without complex soldering operations, greatly improving the flexibility and efficiency of debugging. Preferably, the shorting cap is made of a material with high temperature resistance and low contact resistance to ensure reliability and stability under various test conditions.

[0038] Furthermore, the pins in the multiple groups of first pin groups 41 and multiple groups of second pin groups 42 are relatively arranged on the circuit connection board 3. This design makes full use of the space of the circuit connection board 3, making the layout more compact, and at the same time facilitating the operator to access and control multiple pins simultaneously.

[0039] More preferably, both the first pin group 41 and the second pin group 42 are provided with an upper row group and a lower row group. The upper row group is arranged on the upper surface of the first pin group 41 and the second pin group 42, and the lower row group is arranged on the lower surface of the first pin group 41 and the second pin group 42. Each of the upper row group and the lower row group on one side includes 12 pins. This balanced layout enables the operator to conveniently identify and operate each pin, improving the debugging efficiency. The pin headers 6 are arranged on the upper row group and the lower row group. When the user needs to test individual functions, only by disconnecting or connecting the pin headers 6 can it be achieved.

[0040] In a specific embodiment, pins of GND, VBUS, USB 2.0, and USB 3.2 can be arranged on one side of the circuit connection board 3, while pins of CC and SBU can be arranged on the other side. This layout helps to classify and manage pins with different functions.

[0041] In another embodiment, the utility model further includes wires or pull-down resistors (reference numerals not shown in the figure) disposed between the first pin group 41 and the Type-C male head 1, and between the second pin group 42 and the Type-C female head 2. These additional components provide more debugging options for the operator. For example, by using wires, the operator can simulate various short-circuit conditions; while by using pull-down resistors, different voltage conditions or load conditions can be simulated. Preferably, the wires are coated with a soft and wear-resistant insulating material to ensure operation safety; the resistance value range of the pull-down resistors is selectable from 1 kΩ to 100 kΩ to adapt to different test requirements.

[0042] Preferably, the default state of the multiple first pin groups 41 and the multiple second pin groups 42 is to be electrically connected through the detachable connector 5. This design enables the adapter tool to normally transmit all signals without special settings, facilitating quick conventional tests. When specific pins need to be debugged, the operator only needs to remove the corresponding detachable connector.

[0043] In this embodiment, the multiple first pin groups 41 and the second pin groups 42 include CC pins, SBU pins, VBUS pins, and GND pins. These pins are the parts most frequently in need of debugging in the Type-C interface. The CC (Configuration Channel) pins are used to determine the device role and current capacity; the SBU (Side Band Use) pins are used for the alternate mode; the VBUS pins provide power; and the GND pins are used as the grounding reference. By flexibly controlling these key pins, this adapter tool can meet the requirements of most Type-C interface debugging scenarios.

[0044] In another embodiment, the utility model further includes one or more indicator lights (not shown in the figure) for indicating the connection status of the multiple groups of pins. These indicator lights can be implemented by light-emitting diodes (LEDs), and preferably different colors are used to represent different states. For example, green can indicate normal connection, and red can indicate disconnection or abnormal state. This visual status display greatly improves the intuitiveness and convenience of operation, and helps the operator quickly identify and handle problems.

[0045] The working principle of the present utility model is as follows: When it is necessary to debug a Type-C device, the operator can connect this adapter tool between the device under test and the test device. By operating the detachable connection member 5 (such as a shorting cap), the operator can selectively disconnect or connect specific pin headers. For example, to simulate the situation where the CC pin is disconnected, just remove the corresponding shorting cap; to simulate the situation where VBUS is shorted to GND, a wire can be used to connect these two pin headers. In this way, the operator can flexibly simulate various abnormal situations to test the response and stability of the test device.

[0046] In summary, the present utility model provides a standardized and simple Type-C interface debugging tool. Through reasonable structural design and flexible operation methods, it greatly improves the efficiency and accuracy of Type-C interface debugging. The design of multiple groups of pin headers on the circuit connection board and the detachable connection member enables the operator to conveniently control the states of each pin header without complex soldering operations, thereby reducing the difficulty and risk of debugging. At the same time, this tool supports all 24 standard pin headers of the Type-C interface, covering all standard functions including USB 2.0, USB 3.2, power delivery, and alternate mode, meeting diverse test requirements.

[0047] In addition, the design of the present utility model takes into account the convenience of actual operation. The pin header layout on both sides of the circuit connection board, the setting of indicator lights, and the supporting use of wires and pull-down resistors all provide the operator with more debugging options and a more intuitive operation experience. These features make this tool not only suitable for conventional Type-C interface tests but also capable of flexibly handling various complex debugging scenarios, providing a comprehensive and efficient solution for the development, testing, and troubleshooting of Type-C interfaces. By using this tool, the development efficiency and product quality of Type-C devices can be significantly improved, laying a foundation for the further popularization and application of Type-C technology.

[0048] It should be understood that the above specific embodiments of the present utility model are only used for exemplary illustration or explanation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model. In addition, the appended claims of the present utility model are intended to cover all changes and modification examples falling within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
