Description

Technical Field

[0001] This utility model relates to the field of automotive equipment technology, specifically to a new type of flat wire harness for electrical connections in new energy vehicles. Background Technology

[0002] Automotive wiring harnesses are the main network components of automotive circuits. Their role in the vehicle is to transmit or exchange power or data signals from the electrical system to achieve the functions and requirements of the electrical system. With the development of new energy vehicles, their functions are becoming increasingly diversified, thus placing higher demands on electrical wiring harnesses.

[0003] However, traditional wire harnesses are mostly laid by wrapping soft copper wires inside plastic round insulating tubes, which takes up a lot of space and the cables are concentrated in the tubes, which is not conducive to heat dissipation. Utility Model Content

The top of the upper heat-conducting plate 2 and the bottom of the lower heat-conducting plate 3 are fixedly connected to heat sinks 4. The bottom sides of the lower heat-conducting plate 3 are fixedly connected to pads 8. The bottom of the pads 8 is fixedly connected to adhesive pieces 9 for attaching to the vehicle body.

[0022] The main line 1 and the branch line 11 are flat cables cut from FFC flexible flat cables. Both ends of the main line 1 are fixedly connected to the main connector 13, one end of the branch line 11 is fixedly connected to the branch connector 12, and the other end of the branch line 11 is fixedly connected to the plug 14.

[0023] Fixing plates 1 and 5 are fixedly connected to the four corners of the upper heat-conducting plate 2, and fixing plates 2 and 6 are fixedly connected to the four corners of the lower heat-conducting plate 3. Screws 7 are threaded through the surfaces of fixing plates 1 and 5 and fixing plates 2 and 6. Fixing plates 1 and 5 and fixing plates 2 and 6 are in close contact with each other, and the upper heat-conducting plate 2 and the lower heat-conducting plate 3 are connected together by screws 7, thus wrapping and fixing the main line 1.

[0024] Both sides of the upper heat-conducting plate 2 and the lower heat-conducting plate 3 are fixedly connected with lateral protection plates 10. The two sets of lateral protection plates 10 are attached to each other in a rectangular tube shape. The branch inlet of the main line 1 is located inside the lateral protection plate 10. The lateral protection plate 10 protects the branch inlet.

[0025] The end of the branch line 11 away from the branch connector 12 is slidably inserted into the inner wall of the side protection plate 10, and the plug 14 is slidably inserted into the branch socket on the side of the main line 1. The plug 14 is located inside the side protection plate 10, and the side protection plate 10 protects the branch interface.

[0026] Working principle: The upper heat-conducting plate 2 and the lower heat-conducting plate 3 are respectively wrapped around the top and bottom of the main line 1, and connected and fixed by the screw 7. The adhesive piece 9 is attached to the inner surface of the vehicle body to fix the position of the main line 1. The extension distance of the upper heat-conducting plate 2 and the lower heat-conducting plate 3 can be customized. Different lengths are used as needed and they are arranged at intervals, so that part of the middle of the main line 1 is exposed, which makes it easy to adjust the angle and makes the arrangement more flexible. The main line 1 and the branch line 11 are flat lines cut from FFC soft flat cables, which occupy less area and are flatly distributed, which is beneficial to the upper heat-conducting plate 2 and the lower heat-conducting plate 3. For heat dissipation, the heat sink 4 further improves the heat dissipation effect, solving the problem that traditional wire harnesses are mostly laid by wrapping soft copper wires inside plastic round insulating tubes, which takes up a lot of space and the cables are concentrated in the pipes, which is not conducive to heat dissipation. The side protection plates 10 on the sides of the upper heat conduction plate 2 and the lower heat conduction plate 3 are combined into a rectangular tube. The branch line 11 is connected to the socket on the side of the main line 1 through the plug 14. The side protection plate 10 protects the socket and improves the stability of use. Similarly, the upper heat conduction plate 2 and the lower heat conduction plate 3 can also be set on the branch line 11 as needed for auxiliary heat dissipation.
