[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this utility model. An engine wiring harness fixing bracket includes a fixing plate 1, on which fixing holes 2 are provided. Bolts are installed between the fixing holes 2 on the fixing plate 1 and the vehicle body, so that the fixing plate 1 is fixedly installed on the vehicle body by bolts. The fixing plate 1 has two fixing holes 2.
[0024] The fixing plate 1 has an upwardly extending intermediate plate 12 at one end near the wire harness connecting plate 7. The intermediate plate 12 is connected to the horizontal plate 13, and the wire harness connecting plate 7 is welded to the horizontal plate 13.
[0025] The fixing plate 1 has an upward-facing protrusion 11 on the side opposite to the connector fixing seat 3, and an inner groove is provided in the protrusion 11. The inner groove of this utility model is used for the protrusion 11 on the vehicle body to be inserted, so as to avoid interference between the fixing plate 1 and the vehicle body during installation.
[0026] An L-shaped connector fixing seat 3 is installed on the fixing plate 1. The connector fixing seat 3 includes a vertical plate 4 connected to the fixing plate 1 and a horizontal plate 5 connected to the vertical plate 4. A limiting hole 6 is provided on the horizontal plate 5. The limiting hole 6 is used for the insertion of the pin 18 on the vehicle wiring harness connector 17, thereby realizing the connection between the horizontal plate 5 and the vehicle wiring harness connector 17. A positioning hole 10 is also provided on one side of the fixing hole 2 on the horizontal plate 5. The positioning hole 10 is used for the insertion of the positioning pin 25 on the vehicle wiring harness connector 17, thereby achieving the positioning effect and preventing the vehicle wiring harness connector 17 from rotating around the limiting hole 6.
[0027] One end of the fixing plate 1 is provided with a wire harness connecting plate 7, and one end of the wire harness connecting plate 7 is provided with an upwardly inclined insert plate 8. The insert plate 8 has a slot 9, which is triangular in shape.
[0028] The insert plate 8 is provided with guide flanges 14 on both sides. By setting the guide flanges 14, the slot 9 can be better aligned with the card block when the insert plate 8 is inserted.
[0029] An automotive engine wiring harness fixing structure includes an engine wiring harness 15 and the aforementioned engine wiring harness fixing bracket. One end of the engine wiring harness 15 is provided with an engine wiring harness connector 16, which is connected to a vehicle wiring harness connector 17.
[0030] The bottom of the vehicle wiring harness connector 17 is provided with a pin 18 that is inserted into the limiting hole 6. The pin 18 is provided with a limiting structure, which includes a plurality of elastic wedge-shaped toothed plates 24 that are spaced apart from bottom to top on the pin 18. Each wedge-shaped toothed plate 24 has at least two notches spaced apart. The outer diameter of the upper end of the wedge-shaped toothed plate 24 is larger than the inner diameter of the limiting hole 6. The pin 18 is provided with a tapered head. This utility model provides multiple limiting structures. The toothed plate and tapered head make the pin 18 shaped like a cedar tree. The structure of the pin 18 is similar to the cedar tree-shaped fixing head currently on the market. When the pin 18 is inserted into the limiting hole 6, the limiting hole 6 will press the wedge-shaped toothed plate 24 inward. After being deformed by compression, the wedge-shaped toothed plate 24 will recover under the action of elasticity. After the limiting hole 6 is above the uppermost wedge-shaped toothed plate 24, the pin 18 will be fixed relative to the horizontal plate 5 through the limiting structure. The wedge-shaped toothed plate 24 can effectively prevent the horizontal plate 5 from separating from the pin 18.
[0031] The bottom of the vehicle wiring harness connector 17 is also provided with a positioning pin 25 on one side of the pin 18. The positioning pin 25 is inserted into the positioning hole 10 on the cross plate 5 to fix the position of the vehicle wiring harness connector 17 and prevent the vehicle wiring harness connector 17 from rotating.
[0032] A limiting block 19 is fixedly installed on the engine wiring harness 15. The limiting block 19 has a socket 21 for inserting the insert plate 8. An elastic claw 20 is installed on the upper side of the socket 21 on the limiting block 19. A locking block 22 that can be locked into the locking slot 9 is installed at the bottom of the claw 20. A wedge-shaped surface 23 is provided at the end of the locking block 22 near the inlet of the socket 21.
[0033] When the insert plate 8 of this utility model is connected to the engine wiring harness 15, it is only necessary to insert the insert plate 8 into the insertion hole 21 on the limiting block 19. The insertion hole 21 guides the insert plate 8. During the insertion process, the insert plate 8 contacts the wedge-shaped surface 23 of the locking block 22 and pushes the locking claw 20 upward. Since the locking claw 20 is elastic, it has a downward elastic force, and as the insert plate 8 continues to be inserted, it locks the locking block 22 into the locking groove 9. This completes the fixation of the insert plate 8 and the limiting block 19, and thus completes the fixation of the engine wiring harness 15 and the wiring harness connecting plate 7. The insert plate 8 and the limiting block 19 in this utility model are common snap-fit structures in the prior art.
[0034] A guide block 26 extending downwards is installed on the upper side of the insertion hole 21. The claw 20 is installed on the front side of the guide block 26. The guide block 26 of this utility model cooperates with the guide flanges 14 on both sides of the insertion plate 8. During the insertion of the insertion plate 8, the guide block 26 is between the guide flanges 14 on both sides. The width of the guide block 26 is close to the distance between the guide flanges 14 on both sides. The guide block 26 can ensure that the insertion plate 8 can only move in a straight line.
