[0016] 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. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0017] A cable protection box for an automotive dashboard beam includes a cable protection box body and a clip 10. The cable protection box body includes a front section 1 and a rear section 2 connected to the front section 1. The rear section 2 is inclined relative to the front section 1, and the front section 1 and the rear section 2 are smoothly connected by an arc transition portion 3. The front section 1 includes a front bottom plate 4, and front side plates 5 are formed by extending upwards on both sides of the front bottom plate 4. Two front cable tie holes 6 are provided in the front area of ​​the front bottom plate 4. The rear section 2 includes a rear bottom plate 7, and rear side plates 8 are formed by extending upwards on both sides of the rear bottom plate 7. Two rear cable tie holes 9 are provided in the rear area of ​​the rear bottom plate 7.

[0018] The front section 1 and rear section 2 of this utility model are both U-shaped. Front cable ties are installed in the two front cable tie holes 6. The two ends of the cable ties pass through the two front cable tie holes 6 respectively and fix the instrument wiring harness to the front section 1. Rear cable ties are installed in the two rear cable tie holes 9. The two ends of the cable ties pass through the two rear cable tie holes 9 respectively and fix the instrument wiring harness to the rear section 2.

[0019] The front end of the front section 1 is provided with a front outward flange 27; the rear end of the rear section 2 is provided with a rear outward flange 28. By providing the front outward flange 27 and the rear outward flange 28, this utility model can reduce the friction between the automotive instrument wiring harness and the wiring box body.

[0020] The buckle 10 is installed at the bottom of the front section 1. Two limiting horizontal plates 11 are provided below the bottom surface of the front base plate 4. The limiting horizontal plates 11 are connected to the front base plate 4 through limiting vertical plates 12. The limiting horizontal plates 11 are parallel to the bottom surface of the front base plate 4 and have a certain gap. The gap between the two limiting horizontal plates 11 and the front base plate 4 respectively forms a sliding cavity. The top of the limiting vertical plate 12 is connected to the front base plate 4, and the bottom of the limiting vertical plate 12 is connected to the outer end of the limiting horizontal plate 11. The limiting vertical plate 12 and the limiting horizontal plate 11 have an L-shaped structure.

[0021] The front base plate 4 has a first limiting block 13 installed between the two limiting horizontal plates 11. The first limiting block 13 has a first wedge-shaped surface 14 on the side near the inlet end of the sliding cavity. The first limiting block 13 of this utility model is used to limit the buckle 10.

[0022] A slider is installed on the upper side of the buckle 10. The slider includes a base plate 15. Upright plates 16 are respectively installed on both sides of the base plate 15. The top of the upright plates 16 extends outward horizontally to form a sliding plate 17. The sliding plates 17 on both sides can be inserted into the sliding cavities on both sides.

[0023] The front ends of the two side slide plates 17 are respectively provided with guide slopes 26. By providing guide slopes 26 at the front ends of the two side slide plates 17, this utility model can facilitate the insertion of the two side slide plates 17 into the two side sliding cavities.

[0024] The top surface of the substrate 15 is fitted with a second limiting block 18 that cooperates with the first limiting block 13 between the two side plates 16. The second limiting block 18 has a second wedge-shaped surface 19 on the side near the front end of the slider. When the two side slides 17 of the slider are inserted into the two side sliding cavities, the second wedge-shaped surface 19 of the second limiting block 18 will contact the first wedge-shaped surface 14 of the first limiting block 13. During the relative movement of the first wedge-shaped surface 14 with respect to the second wedge-shaped surface 19, the substrate 15 and the front bottom plate 4 will undergo compressive elastic deformation. When the second limiting block 18 moves to the side of the first limiting block 13 away from the first wedge-shaped surface 14, the elastic deformation is restored, and the first limiting block 13 can prevent the second limiting block 18 from moving backward, thereby preventing the slider from moving backward.

[0025] A baffle 20 is installed at the rear end of the slide plate 17. By installing the baffle 20 at the rear end of the slide plate 17, the forward movement of the slider can be limited. When the baffle 20 at the rear end of the two slide plates 17 contacts the two limiting horizontal plates 11, the two baffles 20 can prevent the slider from moving forward. When the baffle 20 contacts the limiting horizontal plate 11, the second limiting block 18 just moves to the side of the first limiting block 13 away from the first wedge surface 14.

[0026] The outer surfaces of both the front section 1 and the rear section 2 are provided with reinforcing ribs 21. By providing reinforcing ribs 21, this utility model can enhance the strength of the cable box body.

[0027] The buckle 10 includes a top cover 22, which is connected to a support plate 23. The support plate 23 has a front end face 24 and a rear end face 29. The upper part of the front end face 24 and the upper part of the rear end face 29 are both vertical planes and are parallel to each other.

[0028] This invention enables the buckle 10 to have an anti-rotation function by making the upper part of the front end face 24 and the upper part of the rear end face 29 both vertical planes and parallel to each other. The instrument panel tube beam has a long strip-shaped buckle 10 hole. The width of the buckle 10 hole is similar to the distance between the upper part of the front end face 24 and the upper part of the rear end face 29. When the buckle 10 is inserted into the buckle 10 hole, the buckle 10 will not rotate relative to the instrument panel tube beam.

[0029] The lower part of the front end face 24 and the lower part of the rear end face 29 are both inwardly inclined slopes.

[0030] By making the lower part of the front end face 24 and the lower part of the rear end face 29 both inwardly inclined, the present invention makes it easier for the support plate 23 to be inserted into the buckle 10 hole.

[0031] The support plate 23 is provided with claws 25 on its left and right sides respectively.

[0032] When the support plate 23 of this utility model is inserted into the buckle 10 hole of the instrument panel tube beam, the claws 25 on both sides undergo elastic deformation under the action of the buckle 10 hole. When the top cover 22 contacts the top of the instrument panel tube beam, the claws 25 completely pass through the buckle 10 hole and return to their original deformation. The distance between the top of the claws 25 and the bottom surface of the top cover 22 is similar to the wall thickness of the instrument panel tube beam.
