[0038] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the first controller connector 41, the second controller connector 42, and the third controller connector 43 are all constructed as plug-in connectors.

[0039] The connectors can be USB ports, RJ45 ports, D-SUB ports, etc. The first controller connector 41, the second controller connector 42, and the third controller connector 43 can all be configured as connectors.

By configuring the first controller connector 41 with multiple ports to enable wake-up, communication, and power supply functions respectively, the first controller connector 41 can be adapted to the corresponding controller 400 type to complete the flashing operation of the controller 400. Furthermore, the connection can be completed with only one connection between the first controller connector 41 and the connector of the corresponding controller 400, making the operation simple.

[0042] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the second controller connector 42 includes a first sub-connector 421, a second sub-connector 422, and a third sub-connector 423. The first sub-connector 421 is configured as a wake-up connector, the second sub-connector 422 is configured as a communication connector, and the third sub-connector 423 is configured as a power supply connector.

[0043] The second controller connector 42 may have multiple sub-connectors, including a first sub-connector 421, a second sub-connector 422, and a third sub-connector 423. The controller 400 corresponding to the second controller connector 42 may have multiple plug-in parts. The first sub-connector 421 may be configured as a wake-up connector. When the first sub-connector 421 is plugged into the corresponding plug-in part of the corresponding controller 400, a wake-up function can be realized. The second sub-connector 422 may be configured as a communication connector. When the second sub-connector 422 is plugged into the corresponding plug-in part of the corresponding controller 400, a communication function can be realized. The third sub-connector 423 may be configured as a power supply connector. When the third sub-connector 423 is plugged into the corresponding plug-in part of the corresponding controller 400, a power supply function can be realized. By setting the first sub-connector 421, the second sub-connector 422, and the third sub-connector 423, when the second controller connector 42 is plugged into and cooperates with the corresponding controller 400, the wake-up function, communication function, and power supply function can be realized, so that the second controller connector 42 can be adapted to the corresponding controller 400 type to complete the flashing operation of the controller 400.

[0044] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the third controller connector 43 has a socket and integrates wake-up, communication, and power supply functions.

[0045] The third controller connector 43 may have a single socket, and the corresponding controller 400 may have multiple connectors.

[0046] In the above embodiments, by setting the first controller connector 41, the second controller connector 42, and the third controller connector 43 to different types, they are used to connect different types of controllers 400 to meet the needs of different usage scenarios, thereby giving the writing harness 100 a wider range of applications and improving its versatility. As some embodiments of this utility model, the writing harness 100 of this utility model can be equipped with other types of connectors according to actual needs to adapt to various new controllers 400, thereby further improving the versatility of the writing harness 100.

By setting the high-level connector 21 and the low-level connector 22, the writing harness 100 can be electrically connected to the power supply 200 through the power connection component 2 to power the writing harness 100, the controller 400, and, as needed, the host computer 300.

[0049] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, both the high-level connector 21 and the low-level connector 22 are constructed as crimp connectors.

[0050] The crimping component uses mechanical pressure to electrically connect the high-level connector 21 and the low-level connector 22 to the power supply 200. The crimping connection method is simple, secure, and not easily detached, reducing the risk of the crimping component separating from the power supply 200 due to external force. Furthermore, the crimping component is easy to operate, maintain, disassemble, and is not easily damaged. In addition, by constructing both the high-level connector 21 and the low-level connector 22 as crimping components, it can be adapted to different types of power supplies 200, thereby improving the versatility of the power connection assembly 2.

The host computer 300 has a connecting part, and the plug-in connector can be plugged into the connecting part. The connection and disconnection operations between the plug-in connector and the connecting part are relatively convenient and do not require the use of complicated tools. Operators can complete the operation manually, which can reduce the difficulty of operation. In addition, the plug-in connector has a good connection effect, which can improve the connection stability and reliability between the communication port connector 3 and the host computer 300.

[0053] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the wire harness body 1 includes a main wire harness 11 and at least one branch wire harness 12.

[0054] The main wiring harness 11 and the branch wiring harness 12 are used to electrically connect the controller 400, the host computer 300, and the power supply 200. The main wiring harness 11 can be electrically connected to the branch wiring harness 12. Parts of the power connection component 2, the communication port connector 3, and the controller connection component 4 are electrically connected to the main wiring harness 11, and another part of the power connection component 2, the communication port connector 3, and the controller connection component 4 are electrically connected to the branch wiring harness 12. Alternatively, a part of the structure of the power connection component 2 and / or the communication port connector 3 and / or the controller connection component 4 is electrically connected to the main wiring harness 11, and another part of the structure of the power connection component 2 and / or the communication port connector 3 and / or the controller connection component 4 is electrically connected to the branch wiring harness 12.

[0056] This configuration allows for adjustment of the wiring harness lengths of the power connection component 2, communication port connector 3, and controller connection component 4 according to actual needs. This facilitates electrical connection between the writing harness 100 and the power supply 200, host computer 300, and controller 400, ensuring a reasonable distribution of the power supply 200, host computer 300, and controller 400 during connection and avoiding interference. This promotes smooth writing operations and improves efficiency.

[0057] As some embodiments of this utility model, such as Figure 3 As shown, in actual use, the controller connection component 4 can be plugged into the controller 400, the communication port connector 3 can be plugged into the host computer 300, the high-level connector 21 can be crimped into the positive terminal of the power supply 200, and the low-level connector 22 can be crimped into the negative terminal of the power supply 200. The internal wiring principle of the brushing harness 100 is as follows. Figure 3 As shown, after the connection is completed, the power supply 200 can be turned on to enable the writing harness 100 to operate. The controller 400 can be written via the host computer 300. After the writing operation is completed, the power supply 200 is turned off and the writing harness 100 is removed for future use. By using the writing harness 100 of this utility model embodiment, the above process can be made simple and quick, and the writing operation efficiency can be improved.
