Description

Technical Field

[0001] This utility model belongs to the field of automotive wiring harness technology, and in particular relates to a high-temperature resistant and wear-resistant automotive wiring harness. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits; without wiring harnesses, there would be no automotive circuits. A wiring harness is an assembly consisting of copper stamped contact terminals crimped to wires and cables, then covered with plastic insulation or an outer metal shell, and bundled together to form a connected circuit.

[0003] The existing utility model with authorization announcement number CN213601641U discloses a high-temperature resistant automotive wiring harness, including an automotive wiring harness body, and a high-temperature resistant mechanism on the outside of the automotive wiring harness body; the high-temperature resistant mechanism includes an insulating layer disposed on the outside of the automotive wiring harness body, multiple support blocks fixedly disposed on the outside of the automotive wiring harness body, a high-temperature resistant layer fixedly disposed on the outside of the insulating layer, a wear-resistant layer fixedly disposed on the outside of the high-temperature resistant layer, a rubber layer fixedly disposed on the outside of the wear-resistant layer, a waterproof layer fixedly disposed on the outside of the rubber layer, and heat-conducting plates fixedly connected to both sides of the automotive wiring harness body.

[0004] The above technical solution, by setting an insulation layer on the outside of the automotive wiring harness body, prevents safety issues such as leakage during use. The addition of a high-temperature resistant layer and a wear-resistant layer improves the high-temperature resistance of the wiring harness, extending its service life. The inclusion of a rubber layer and a waterproof layer provides good waterproofing, preventing water from entering the wiring harness and causing short circuits or damage to the vehicle. However, this technical solution requires the wiring harness clips to be inserted into the vehicle's connection slots during installation. This method of connection is less effective, as the clips are prone to deformation and damage, preventing them from engaging properly. This can lead to poor connection or even detachment of the wiring harness from the vehicle's terminals, ultimately affecting its usability.

[0005] Therefore, we propose a high-temperature resistant and wear-resistant automotive wiring harness to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem of unstable connection between automotive wiring harnesses and automotive terminals in the prior art, and to propose a high-temperature resistant and wear-resistant automotive wiring harness.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A high-temperature and wear-resistant automotive wiring harness includes several wiring harness connecting wires. The right ends of all the wiring harness connecting wires are fixedly connected to an insulating connector. A connecting plate is fixedly connected to both the front and back of the insulating connector. Each connecting plate has a limiting groove on its left side, and a positioning bolt is slidably connected inside each limiting groove. A partial automotive terminal is located on the right side of the insulating connector. Two threaded cylinders are fixedly connected to the left side of the partial automotive terminal. Each positioning bolt is threaded into the inside of a threaded cylinder, and a positioning nut is threaded onto the outer surface of each positioning bolt. The right side of each positioning nut contacts the left side of the connecting plate.

[0009] Preferably, the outer surfaces of several of the wire harness connecting wires are jointly fitted with a high-temperature and wear-resistant sleeve, which is made of high-temperature and wear-resistant polytetrafluoroethylene.

[0010] Preferably, a connecting buckle is fixedly connected to the right side of the insulating connector, and a connecting groove is opened on the left side of the partial vehicle terminal, with the connecting buckle snapping into the inside of the connecting groove.

[0011] Preferably, the right side of the insulating connector is fixedly connected with connecting posts arranged at equal intervals, and the left side of the partial vehicle terminal is provided with connecting holes arranged at equal intervals, with each connecting post snapped into the inside of the connecting hole.

[0012] Preferably, a snap-fit ​​buckle is fixedly connected to the upper surface of the insulating connector, and an mounting block is fixedly connected to the left side of the partial vehicle terminal. A snap-fit ​​cavity is opened on the left side of the mounting block, and the snap-fit ​​buckle snaps into the inside of the snap-fit ​​cavity.

[0013] Preferably, a disassembly cylinder is fixedly connected to the upper surface of the mounting block, the disassembly cylinder is connected to the snap-fit ​​cavity, and a disassembly column is slidably connected inside the disassembly cylinder, the disassembly column being slidably connected inside the snap-fit ​​cavity.

[0014] Preferably, a pressing plate is fixedly connected to the outer surface of the disassembly column, and a restoring spring is fixedly connected to the bottom surface of the pressing plate. Both the pressing plate and the restoring spring are slidably connected inside the disassembly cylinder, and the bottom end of the restoring spring is in contact with the upper surface of the mounting block.

[0015] Preferably, each of the positioning bolts and each positioning nut has a rotating rod fixedly connected to its outer surface at equal intervals, and a rotating handle is fixedly connected to the ends of the rotating rods that are far apart from each other.

[0016] In summary, the technical effects and advantages of this utility model are as follows: By incorporating a wire harness connector, an insulating connector, a connecting plate, a limiting groove, a positioning bolt, and a threaded cylinder, before connecting the wire harness connector and the insulating connector to a portion of the vehicle terminal, the positioning bolt in the limiting groove is threadedly connected to the threaded cylinder. This allows the connecting plate to pre-position the insulating connector to the portion of the vehicle terminal, thus ensuring a stable connection between the vehicle wire harness and the vehicle terminal. Furthermore, the positioning nut outside the positioning bolt can be twisted to press against the connecting plate, further ensuring a stable connection between the insulating connector and the portion of the vehicle terminal. This reduces the risk of poor connection or even detachment of the vehicle wire harness due to deformation or damage to the clips preventing them from locking into the connecting groove, thus ensuring the stable use of the vehicle wire harness.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 5This embodiment provides a high-temperature and wear-resistant automotive wiring harness, which includes a plurality of wiring harness connecting wires 1. The outer surfaces of the plurality of wiring harness connecting wires 1 are collectively covered with a high-temperature and wear-resistant sleeve 2. The high-temperature and wear-resistant sleeve 2 is made of high-temperature and wear-resistant polytetrafluoroethylene (PTFE). The high-temperature and wear-resistant sleeve 2 made of PTFE protects the wiring harness connecting wires 1 of the automotive wiring harness, thereby improving the high-temperature and wear-resistant performance of the automotive wiring harness.

[0025] An insulating connector 3 is fixedly connected to the right end of several wire harness connectors 1. A connecting plate 9 is fixedly connected to both the front and back of the insulating connector 3. A limiting groove 10 is opened on the left side of each connecting plate 9. A positioning bolt 11 is slidably connected inside each limiting groove 10. A portion of the automotive terminal 20 is provided on the right side of the insulating connector 3. A connecting buckle 4 is fixedly connected to the right side of the insulating connector 3. A connecting groove 6 is opened on the left side of the portion of the automotive terminal 20. The connecting buckle 4 is snapped into the inside of the connecting groove 6. By snapping the connecting buckle 4 into the inside of the connecting groove 6, the insulating connector 3 can be connected to the portion of the automotive terminal 20, thereby enabling the automotive wire harness to be connected to the automotive terminal.

[0026] The right side of the insulating connector 3 is fixedly connected with connecting posts 5 arranged at equal intervals. The left side of some automotive terminals 20 is provided with connecting holes 7 arranged at equal intervals. Each connecting post 5 is snapped into the inside of the connecting hole 7. By snapping the connecting post 5 into the inside of the connecting hole 7, the insulating connector 3 and some automotive terminals 20 can be connected for data, thereby enabling the automotive wiring harness to be connected to the automotive terminal for data.

[0027] Two threaded cylinders 8 are fixedly connected to the left side of some automotive terminals 20. Each positioning bolt 11 is threaded into the inside of the threaded cylinder 8. A snap-fit ​​buckle 17 is fixedly connected to the upper surface of the insulating connector 3. A mounting block 15 is fixedly connected to the left side of some automotive terminals 20. A snap-fit ​​cavity 16 is opened on the left side of the mounting block 15. The snap-fit ​​buckle 17 snaps into the inside of the snap-fit ​​cavity 16. By snapping the snap-fit ​​buckle 17 into the snap-fit ​​cavity 16 opened on one side of the mounting block 15, the connection between the insulating connector 3 and some automotive terminals 20 can be strengthened, thereby improving the connection stability between the automotive wiring harness and the automotive terminal.

[0028] A disassembly cylinder 18 is fixedly connected to the upper surface of the mounting block 15. The disassembly cylinder 18 is connected to the snap-fit ​​cavity 16. A disassembly post 19 is slidably connected inside the disassembly cylinder 18. The disassembly post 19 is slidably connected inside the snap-fit ​​cavity 16. By manually pressing the disassembly post 19 inside the disassembly cylinder 18, the disassembly post 19 is used to squeeze the snap-fit ​​buckle 17 inside the snap-fit ​​cavity 16, thereby facilitating the disassembly of the automotive wiring harness.

[0029] A pressing plate 21 is fixedly connected to the outer surface of the disassembly column 19, and a restoring spring 22 is fixedly connected to the bottom surface of the pressing plate 21. Both the pressing plate 21 and the restoring spring 22 are slidably connected inside the disassembly cylinder 18. The bottom end of the restoring spring 22 is in contact with the upper surface of the mounting block 15. When the disassembly column 19 presses the snap fastener 17 in the snap-fit ​​cavity 16, the pressing plate 21 can press the restoring spring 22, causing it to accumulate a large amount of elastic force, thus making it easy to restore the disassembly column 19 to its unused state after use.

[0030] Each positioning bolt 11 has a positioning nut 12 threaded onto its outer surface. The right side of each positioning nut 12 is in contact with the left side of the connecting plate 9. Each positioning bolt 11 and each positioning nut 12 has a rotating rod 13 fixedly connected to its outer surface at equal intervals. A rotating handle 14 is fixedly connected to the ends of the rotating rods 13 that are far apart from each other. By manually holding the rotating handle 14, the positioning bolt 11 and positioning nut 12 can be rotated using the rotating rods 13, thus facilitating the installation and connection of the automotive wiring harness by rotating the positioning bolt 11 and positioning nut 12.

[0031] The working principle of this utility model is as follows: When using this automotive wiring harness to connect to an automotive terminal, the insulating connector 3 is manually held, allowing the positioning bolt 11 to slide within the limiting groove 10 on one side of the connecting plate 9. The positioning bolt 11 aligns with the threaded cylinder 8 fixed on one side of the automotive terminal 20. The rotating handle 14 is then manually held, and the rotating rod 13 is used to twist the positioning bolt 11 until it is threadedly connected to the threaded cylinder 8. At this point, the positioning bolt 11 can slide within the limiting groove 10 by moving the insulating connector 3, thus completing the pre-positioning of the insulating connector 3. Then, by manually pushing the insulating connector 3, the connecting buckle 4 and multiple connecting posts 5 fixed on one side of the insulating connector 3 can be engaged into the connecting groove 6 on one side of the automotive terminal 20. Within the multiple connection holes 7, the snap-fit ​​buckle 17 fixed on the insulating connector 3 can slide and snap into the snap-fit ​​cavity 16 opened on one side of the mounting block 15. The special shape of the snap-fit ​​buckle 17 and the snap-fit ​​cavity 16 makes it easy for the two to snap together. Then, by manually holding the rotating handle 14 provided on the outside of the positioning nut 12, the positioning nut 12 is rotated and moved on the external thread of the positioning bolt 11 by the rotating rod 13 until the positioning nut 12 can contact and press against the connecting plate 9. At this time, the automotive wiring harness can be stably connected to the automotive terminal. When disassembling the automotive wiring harness, by manually pressing the disassembly column 19 in the disassembly cylinder 18, the disassembly column 19 can be used to press the snap-fit ​​buckle 17 in the snap-fit ​​cavity 16, so that the snap-fit ​​buckle 17 can be pulled out from the snap-fit ​​cavity 16. The above steps can be repeated to disassemble the automotive wiring harness.
