[0002] The wiring harness of new energy vehicles is a key component that connects batteries, motors and other high-voltage equipment, and undertakes the important tasks of power transmission and control signal transmission. They not only ensure the efficient and high-quality transmission of electric energy, but also shield external signal interference to ensure the safe operation of the vehicle. According to their functions and positions, the wiring harness of new energy vehicles can be divided into power battery high-voltage wiring harness, motor controller high-voltage wiring harness, fast charging wiring harness, slow charging wiring harness and high-voltage accessory wiring harness, etc., which are responsible for connecting the power battery with the high-voltage distribution box, motor controller, fast charging port, low-power AC charging port and other high-voltage components of the vehicle. The design and manufacture of these wiring harnesses must strictly follow a series of standards, use high-quality conductor materials and high-performance insulation materials to ensure good electrical performance, durability and safety. In the power system of new energy vehicles, wiring harnesses play an irreplaceable role as "power arteries", promoting the sustainable development of the new energy vehicle industry.

[0003] For example, the Chinese authorized patent "A wiring harness for new energy vehicles with resistance to electromagnetic interference" with announcement number CN216487395U includes a terminal, a protective seat and a cable.

The excellent electromagnetic shielding performance of the electromagnetic shielding layer can be used to isolate the electromagnetic radiation generated by external electrical equipment.

[0004] Although the above-mentioned existing technology can be used to realize the transmission of power of new energy vehicles, during the installation and arrangement of the wiring harness, due to the limited internal space of the vehicle body, it is difficult to connect the end and the power component connector during the installation process.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention independently designs the connector and the wiring harness terminal, abandons the traditional manual calibration and plug-in method, and the wiring harness terminal is placed in a guide seat at one end of the connector. The inner cavity of the guide seat can locate the terminal position, thereby directly aligning the plug-in end of the terminal with the input end of the connector. After closing the protective cover, the staff rotates the second rotating wheel to drive the active gear to rotate, and drives the driven gear to rotate under the meshing action. The other side of the driven gear meshes with the rack of the guide seat side plate, thereby driving the guide seat to move toward the connector, and gradually pushing the terminal into the input end of the connector, thereby achieving a fixed connection between the two, effectively solving the problem of difficulty in docking caused by space limitation during the installation of the wiring harness of new energy vehicles, not only realizing accurate and automatic alignment of the terminal with the input end of the connector, but also ensuring the firmness of the installation through mechanical transmission, avoiding the angular deviation and subsequent looseness that may be caused by manual calibration and plug-in, and significantly improving the installation efficiency and connection reliability.

[0020] 2. The present invention provides an annular latch inside the active gear and designs a spring reset mechanism between the movable claw and the movable rod. The flexible automotive wiring harness not only achieves precise docking and firm connection during installation, but also further enhances the firmness and stability of the plug-in connection between the terminal and the connector. In normal use, the movable claw slides smoothly along the back of the latch tooth without affecting the counterclockwise rotation of the active gear; once an attempt is made to pull the terminal from the outside, the clockwise rotation force generated by the driven gear on the active gear will be effectively limited by the movable claw, thereby preventing unauthorized or accidental separation. In addition, by rotating the third wheel to drive the friction fit between the screw rod and the screw hole in the active rod, and the guiding effect of the limit groove, the separation of the movable claw and the annular latch can be easily achieved, and then the connector and the terminal can be easily separated by rotating the second wheel in the opposite direction, which not only ensures the reliability of the connection, but also provides a convenient disassembly method, greatly improving the convenience and safety of the wiring harness connection.

[0021] 3. The present invention sets an auxiliary clamping structure in the end seat. When the end seat at the other end of the wiring harness is installed with another power component, the output end of the power component is inserted into the value end seat. The staff drives the worm to rotate by rotating the first rotating wheel. The contact surface between the worm and the worm wheel forms a spiral friction transmission surface. The rotation of the worm drives the worm wheel to rotate, thereby realizing the rotation of the transmission gear. The transmission gear meshes with the rack plate, thereby driving the clamping plate to move toward the plug direction of the power component until it forms a tight fit with it. The self-locking property of the worm gear is utilized to not only improve the convenience and efficiency of installation, but also ensure the stability and reliability of the connection, effectively prevent potential safety hazards caused by loose connection, and provide a strong guarantee for the safe and stable operation of the power transmission system of new energy vehicles.

The overall structural design greatly improves the comprehensive performance and service life of the cable.

[0042] Working principle: When in use, place the wiring harness terminal 2 in the guide seat 5 at one end of the connector 4. The inner cavity of the guide seat 5 can locate the position of the terminal 2, so that the plug-in end of the terminal 2 is directly aligned with the input end of the connector 4. After closing the protective cover 6, the staff rotates the second rotating wheel 15 to drive the active gear 9 to rotate, and drives the driven gear 10 to rotate under the meshing action. The other side of the driven gear 10 meshes with the rack 11 of the side plate of the guide seat 5, thereby driving the guide seat 5 to move toward the connector 4, and gradually pushes the terminal 2 to the input end of the connector 4, thereby achieving a fixed connection between the two. During the plug-in process, the active gear 9 rotates counterclockwise. During the rotation, the active claw 13 passes over the tooth back of the annular tooth 14 without entering the annular tooth 14. At the same time, the spring 21 between the active rod 12 and the active claw 13 allows the active claw 13 to be continuously reset to ensure the normal counterclockwise rotation of the active gear 9. Then, when the end seat 3 at the other end of the harness is installed with another power assembly, the output end of the power assembly is inserted into the end seat 3. The staff rotates the first rotating wheel 7 to drive the worm 26 to rotate. The contact surface between the worm 26 and the worm wheel 25 forms a spiral friction transmission surface. The rotation of the worm 26 drives the worm wheel 25 to rotate, realizing the rotation of the transmission gear 24. The transmission gear 24 meshes with the rack plate 27, and then drives the clamping plate 23 to move toward the plug of the power assembly until it forms a tight fit with it. When it is necessary to separate the terminal 2 from the connector 4, if the terminal 2 is directly pulled toward the outside of the connector 4, the driven gear 10 will generate a clockwise rotation force on the driving gear 9. Restricted by the movable claw 13, the driving gear 9 cannot rotate clockwise, thereby ensuring the firmness and stability of the connection between the terminal 2 and the connector 4. When the two need to be separated, the screw 17 at one end is driven to rotate by rotating the third rotating wheel 16. Under the friction with the screw hole in the movable rod 12, the movable rod 12 and the movable claw 13 are driven to move upward with the guiding effect of the limiting groove 19 on the upper end of the movable rod 12, so as to achieve separation from the annular tooth 14 inside the driving gear 9. At this time, the connector 4 and the end 2 can be separated by rotating the second rotating wheel 15 in the opposite direction.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
