Description
New energy vehicle high-voltage wiring harness Technical Field
[0001] The utility model belongs to the technical field of high-voltage wire harnesses and relates to a high-voltage wire harness for new energy vehicles. Background Art
[0002] The automotive high-voltage wiring harness, also known as the vehicle's "neural network," is an indispensable system-level component that connects all electronic and electrical components within the vehicle, provides stable power and signal data for the entire vehicle, and enables all electrical functions. In new energy electric vehicles, the high-voltage wiring harness is the primary carrier of the vehicle's power output. It connects all components in the high-voltage system and features high voltage, high current, anti-electromagnetic interference, and a high level of protection. It plays a role in ensuring the performance and safety of the entire vehicle. High-voltage cables for new energy vehicles are generally composed of high-voltage cables, connectors, protective materials, insulation pipes, braided pipes, mounting brackets or rolled strips, sealing rubber rings, tape, heat shrink tubing, and labels.
[0003] The existing high-voltage wiring harness plays the role of transmitting electricity in new energy electric vehicles. Due to the large number of electronic components and machines inside the car, the specifications and types of the required wiring harnesses are varied, and the number of wiring harnesses required is also very large. This causes the wiring harnesses inside the car to be intertwined and interwoven, and the complicated wiring harnesses are placed in a disorderly manner. It will be difficult to repair and replace the high-voltage wiring harnesses in the later stage. At the same time, since the wiring harnesses installed in an interwoven manner are energized, and due to the alternating current used in new energy vehicles, eddy currents will be formed between the adjacent wiring harnesses placed in a disorderly manner, causing the wires to heat up. At the same time, since the high-voltage wiring harness is generally installed inside the car, various insulation materials will also be installed on the outside of the high-voltage wiring harness. In the long run, the heating of the wires will cause a short circuit and lead to a fire. Utility Model Content

Two hook-shaped plates 7 are symmetrically installed on the left and right sides of the No. 2 power terminal 3, and the outer contour of the hook-shaped plate 7 is a hook-shaped shape. A slide rail 70 that passes through the outer wall is provided in front of the hook-shaped plate 7, and a through hole 71 that passes through the outer wall is provided at the rear of the slide rail 70. At the same time, a connecting plate 72 is installed between adjacent hook-shaped plates 7, and a No. 1 channel 50 and a No. 2 channel 51 are provided in the middle of the upper shell 5. Blocks 52 are symmetrically installed at the outer edge of the upper shell 5, and an extension block 53 is installed on the left outer wall of the upper shell 5. The extension block 53 has a threaded hole 54 that passes through the outer wall horizontally.
[0030] In this embodiment, the wire 11 is a high-voltage wire harness inside a new energy vehicle. Its main function is to connect one end of the wire 11 to the power supply inside the vehicle, and the other end thereof to various electronic components inside the vehicle to provide power for the electronic components. At the same time, two raised cylindrical blocks are symmetrically installed at both ends of the second power terminal 3, and the diameter of the cylindrical blocks here is smaller than the through hole 71.
[0031] As shown in Figures 1 and 3 , a metal bracket 12 and a second plastic shield 13 are mounted in the middle of the wire 11. A compressor head 14 is mounted at the other end of the wire 11. The wire 11 is electrically connected to the power supply via terminals 1 and 3. The other end of the wire 11 is connected to the compressor inside the vehicle via the compressor head 14.
[0032] As shown in Figures 3 and 4, the lower shell 6 is provided with a No. 1 cover plate 60 and a No. 2 cover plate 61. A number of limit blocks 62 are installed on the inner wall of the lower shell 6, and a card slot 63 of the outer wall is provided at the edge of the lower shell 6. The limit blocks 62 are symmetrically distributed on the inner wall of the lower shell 6, and the card slots 63 are symmetrically distributed on the outer wall of the lower shell 6. The limit blocks 62 are located on the rear side of the card slots 63. A partition is installed between the No. 1 cover plate 60 and the No. 2 cover plate 61, and a partition is installed between the No. 1 channel 50 and the No. 2 channel 51. The size of the upper shell 5 is smaller than that of the lower shell 6. The card slot 63 on the lower shell 6 and the card block 52 on the upper shell 5 correspond to each other, and the size of the card block 52 is smaller than the card slot 63.
[0033] Specifically, the upper shell 5 and the lower shell 6 together form a plastic guard plate No. 1. The size of the upper shell 5 is smaller than that of the lower shell 6. During installation, the upper shell 5 is placed vertically in the lower shell 6. The edge of the upper shell 5 is located in the area between the slot 63 and the limit block 62, and the block 52 is inserted into the slot 63.
[0034] As shown in Figures 6 and 7 , several collars 80 are installed at intervals on the conductor 11. An elastic block 8 and a fixed rod 9 are mounted below the collars 80. A sliding rod is mounted within the elastic block 8, and symmetrically mounted on either side of the sliding rod are molded plates 81. One end of each molded plate 81 is fixedly connected to the bottom of the sliding rod and is made of an elastic material. Several serrated blocks 90 are symmetrically mounted on the outer wall of the fixed rod 9, with adjacent serrated blocks 90 spaced evenly apart.
[0035] Specifically, holes and threaded holes 54 are provided on the panel of the routing path of the wires 11 inside the car. When arranging the wires, the elastic block 8 and the fixing rod 9 are directly inserted into the holes. The plastic plate 81 is similar to a simple expansion screw. During the insertion, the plastic plate 81 will tilt inward, and when passing through the hole, the plastic plate 81 will tilt outward and return to its original shape. Then the plastic plate 81 will support the inner wall of the hole, and at the same time, the serrated block 90 will press against the inner wall edge of the hole in reverse, thereby fixing the wire 11 on the panel inside the car.
[0036] The working principle of this utility model is:
[0037] The ring 80 equipped with the elastic block 8 , the shaping plate 81 , the fixing rod 9 , and the serrated block 90 is inserted onto the wire 11 .
[0038] Before installing the cable, first attach one end of the shorter wire 11 to the second terminal 3, then attach the other end of the shorter wire 11 to the compressor head 14. Attach one end of the longer wire 11 to the first terminal 2, then attach the other end of the longer wire 11 to the metal connector. Fasten the second terminal 3 to the connecting plate 72, and lock the cylindrical blocks attached to both ends of the second terminal 3 into the through-hole 71.
[0039] After electrically connecting the No. 1 power terminal 2 and the No. 2 power terminal 3 to the power supply device inside the new energy vehicle, the compressor head 14 is connected to the compressor inside the new energy vehicle, and the metal connector at one end of the shorter wire 11 is connected to the PCM device inside the vehicle.
[0040] Since a total of three wires 11 are installed in this new type of use, two of which are short and one is long, and the wires 11 of different lengths are responsible for different duties, in order to standardize the routing of the wires 11, the two shorter wires 11 are placed in channel 1 50, and the longer wire 11 is placed in channel 2 51. The upper shell 5 is installed near the end where the metal connector is installed, and then the upper shell 5 is vertically placed in the lower shell 6. The edge of the upper shell 5 is located in the area between the card slot 63 and the limit block 62. The card block 52 is inserted into the card slot 63. The limit block 62 mainly cooperates with the outer wall of the lower shell 6 to limit the upper shell 5 therein to prevent the card slot 63 from falling off from the limit block 62.
[0041] After the connection is completed, when arranging the wires, the elastic block 8 and the fixing rod 9 will be directly inserted into the hole. The molding plate 81 is similar to a simple expansion screw. During the insertion, the molding plate 81 will tilt inward. When passing through the hole, the molding plate 81 will tilt outward and return to its original shape. Then the molding plate 81 will press against the inner wall of the hole, and at the same time, the serrated block 90 will press against the inner wall edge of the hole in reverse, thereby fixing the wire 11 on the panel inside the car.
