Description

Technical Field

[0001] This utility model relates to the field of interface signal testing technology, and more specifically, to a USB TYPE-C interface signal testing device. Background Technology

[0002] With the widespread use of electronic devices, the USB Type-C interface is widely used in various devices such as mobile phones and computers due to its advantages such as fast transmission speed and support for bidirectional power supply. However, its internal channels and paths are complex, and problems such as signal transmission failure or abnormal charging path may occur during use. When signal transmission failure or abnormal charging path occurs, repair is required.

[0003] However, the existing interface signals have the following problems during testing: When performing interface testing on existing equipment, analog signals are usually used, and then multimeters are used for testing. This method cannot accurately and quickly pinpoint the faulty channel, nor can it provide intuitive feedback on the specific status of each channel and path. Maintenance personnel need to spend a lot of time troubleshooting, which seriously affects the efficiency of fault repair and cannot meet the actual needs of rapid location and efficient repair.

[0004] This invention can work in conjunction with multiple buttons and toggle switches to adapt to different brands of equipment, provide intuitive feedback on the status of each channel and path, help maintenance personnel quickly locate problems, improve the efficiency of interface fault repair, and simplify testing operations. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a USB TYPE-C interface signal testing device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a USB TYPE-C interface signal testing device, comprising: a base plate, a toggle switch fixedly connected to the middle of the upper end of the base plate, a CC1 button fixedly connected to the right side of the front side of the upper end of the base plate, a CC2 button fixedly connected to the left side, a DP button and a DN button fixedly connected between the CC1 button and the CC2 button, the DP button being positioned close to the CC2 button, the DN button being positioned close to the CC1 button, a CC1 indicator light and a CC2 indicator light fixedly installed on the rear side of the CC1 button and the CC2 button respectively, a DP indicator light and a DN indicator light fixedly installed on the rear side of the DP button and the DN indicator light, and an interface one fixedly installed at the front end of the indicator light, and an interface two fixedly installed at the rear end of the base plate.

[0007] A further preferred embodiment: the CC1 button, CC2 button, DP button and DN button are all located on the side close to interface one.

[0008] A further preferred embodiment: the toggle switch is located on the side near interface two, and 5V indicator lights and 9V indicator lights are fixedly installed on the left and right sides respectively.

[0009] A further preferred option: both Interface 1 and Interface 2 are TYPE-C interfaces.

[0010] A further preferred embodiment: Interface 1 is connected to the main body of the power supply equipment, and Interface 2 is connected to an external device. Beneficial effects

[0011] 1. Equipped with CC1 and CC2 buttons, these buttons can simulate a signal pull-down, triggering the OTG access recognition and power supply response of the power supply equipment. Path detection can be started without complicated operations. During detection, pressing the corresponding button and observing the indicator light changes allows for a direct assessment of whether the corresponding path is normal. This avoids the problems of traditional detection methods that require complex instruments or cumbersome procedures. When the indicator light turns off as expected and the target indicator light illuminates, the path can be quickly confirmed to be clear. If the expected response does not occur, the problematic path can be directly identified, significantly reducing the time for maintenance personnel to troubleshoot and improving detection and maintenance efficiency. It is especially adaptable to the differences in equipment from different brands, ensuring a stable and reliable detection process. 2. By providing DN and DP buttons, a precise and convenient operating platform is provided for DN and DP channel testing. When testing the DP channel, simply connect the external device data cable to interface two, press and hold the DN button, and observe whether the DP indicator light flashes to intuitively determine whether the DP channel is normal, without the need for complex instrument readings, simplifying the testing process. When testing the DN channel, the app plays sound on a mobile phone. After pressing the corresponding button, the DN indicator light can be used to quickly confirm the continuity of the DN channel, making signal transmission problems clear at a glance. This design, through the linkage of buttons and indicator lights, transforms abstract channel testing into visual status feedback, helping maintenance personnel quickly distinguish different channel faults, avoid confusion, and significantly improve the efficiency and accuracy of channel testing. At the same time, the operation logic is clear, adaptable to the testing needs of different scenarios, and lowers the operating threshold. 3. By incorporating a toggle switch, the issue of power supply discrepancies between different brands of equipment can be effectively resolved. When the device is connected to another device, if key indicator lights fail to illuminate due to brand differences, there is no need to adjust complex parameters or replace test components. Simply toggle the toggle switch to quickly achieve power supply compatibility between the device and the equipment, ensuring that key indicator lights illuminate normally. This lays the foundation for subsequent interface signal testing. At the same time, different voltage indicator lights are provided next to the toggle switch, providing intuitive feedback on the power supply status. Combined with the overall testing process, this eliminates the need for maintenance personnel to repeatedly troubleshoot power supply compatibility issues, further improving the convenience and efficiency of testing operations and preventing delays in fault location due to power supply compatibility problems. 4. In summary, this USB TYPE-C interface signal testing device, through the inclusion of CC1, CC2, DN, DP buttons, and a toggle switch, forms a highly efficient and adaptable interface testing system. The toggle switch first addresses the power supply identification differences between different brands of equipment, quickly completing power supply adaptation and clearing obstacles for subsequent testing. The CC1 and CC2 buttons can specifically test corresponding paths, allowing for intuitive judgment of path normality through indicator light status, helping repair personnel quickly locate problems. The DN and DP buttons are adapted to DN and DP channel testing scenarios respectively, and combined with external devices or mobile APP operation, accurately feedback the channel status. The coordinated use of these multiple structures not only improves the convenience of testing operations but also ensures the accuracy of fault diagnosis, effectively shortening the testing and troubleshooting time for repair personnel and significantly improving the efficiency of USB TYPE-C interface fault repair.

[0016] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0017] Please see Figure 1-3In this embodiment of the present invention, a USB TYPE-C interface signal testing device includes: a base plate 1; a toggle switch 2 is fixedly connected to the middle of the upper end of the base plate 1; a CC1 button 103 is fixedly connected to the right side of the front side of the upper end of the base plate 1, and a CC2 button 104 is fixedly connected to the left side; a DP button 105 and a DN button 106 are fixedly connected between the CC1 button 103 and the CC2 button 104; the DP button 105 is positioned close to the CC2 button 104, and the DN button 106 is positioned close to the CC1 button 103; a CC1 indicator light 107 and a CC2 indicator light 108 are fixedly installed on the rear sides of the CC1 button 103 and the CC2 button 104, respectively; and the DP button 105... DP indicator light 110 and DN indicator light 109 are fixedly installed on the rear side of DN button 106. Interface 1 101 is fixedly installed on the front end of base plate 1, and interface 2 102 is fixedly installed on the rear end of base plate 1. CC1 button 103, CC2 button 104, DP button 105, and DN button 106 are all located on the side near interface 1 101. Toggle switch 2 is located on the side near interface 2 102, and 5V indicator light 201 and 9V indicator light 202 are fixedly installed on its left and right sides, respectively. Interface 1 101 and interface 2 102 are both TYPE-C interfaces. Interface 1 101 is connected to the main body of the power supply equipment, and interface 2 102... When connecting to an external device and using this device to test the device interface, first insert interface 101 into the phone's charging port. The phone will then recognize the device and become the power source, supplying power to the device. At this time, indicator lights 107 (CC1) and 108 (CC2) on the base plate 1 will illuminate. Due to differences between phone brands, if indicator lights 107 (CC1) and 108 (CC2) do not illuminate after device insertion, toggle switch 2 to the other side to illuminate indicator lights 107 (CC1) and 108 (CC2). Once both indicator lights 107 (CC1) and 108 (CC2) are illuminated, the process begins. In the test, pressing the CC1 button will turn off both the CC1 indicator light 107 and the CC2 indicator light 108, while the 5V indicator light 201 will light up, indicating that the CC1 path detection is normal. Similarly, pressing the CC2 button will turn off both the CC1 indicator light 107 and the CC2 indicator light 108, while the 5V indicator light 201 will light up, indicating that the CC2 path detection is normal. Otherwise, it indicates that there is a problem with the path transmission, which can quickly locate the problem path. During the entire process, pressing the CC1 button 103 and the CC2 button 104 will simulate a signal pull-down, making the mobile phone think that OTG is connected, and then perform power supply identification, thereby realizing the indicator lights turning on or off.When testing the DN and DP channels, insert the external device data cable into interface 102, then press and hold the DN button 106. The DP indicator light 110 will flash, indicating the DP channel is normal. When testing the DN channel, open any app on your phone that can play sound. If the DN indicator light 109 lights up while playing sound, the DN channel is normal. Otherwise, it indicates a problem with the channel path and requires repair. When testing the charging path channel, insert the charging data cable into interface 102. Both the 5V indicator light 201 and the 9V indicator light 202 will light up, indicating the fast charging channel is normal. If the 9V indicator light 202 is not lit, first check the device's battery level. If the battery is too high, the fast charging channel will not be activated according to the fast charging protocol. In this case, discharge the battery by draining it before testing again. If the 9V indicator light remains off, it indicates a problem with the fast charging channel path. This device uses digital signals for channel detection, and the flashing of indicator lights provides a more intuitive indication of whether there is a problem with the path channel, allowing repair personnel to quickly and accurately locate the problematic channel.
