Description

Technical Field

[0001] This utility model relates to a fixing device for automotive wiring harnesses, belonging to the field of automotive wiring harness construction technology. Background Technology

[0002] In the modern automotive industry, automotive wiring harnesses serve as the core hub of a vehicle's electrical system, undertaking the dual mission of power transmission and signal interaction. With the accelerated evolution of automotive intelligence and electrification, the complexity of wiring harness systems is increasing exponentially. The scientific nature of their layout design and fixing methods has become a key factor directly affecting the safety, reliability, and service life of the entire vehicle. Currently, when conduits and multiple wiring harnesses are arranged together, cable ties are used to bundle the conduits and harnesses together, forming a circular bundle.

[0003] Current technology is not comprehensive and has the following drawbacks: During actual driving, cars inevitably encounter continuous vibrations from road bumps, engine operation, and other factors. The pipes and wiring harnesses are bundled into a circle, which cannot effectively isolate the two. After fixing, there is room for sliding between the wiring harness and the pipes. When the car is in motion, the wiring harness will rub against the pipes, causing wear and tear on the wiring harness.

[0004] To solve one of the above problems, there is an urgent need for a fixing device for automotive wiring harnesses. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to use the elasticity of the elastic band to fix the wire harness in the corresponding positioning slot A, so as to achieve the fixation of the wire harness, with simple structure, convenient operation and convenient use. Therefore, a fixing device for automotive wire harness is provided.

[0006] The automotive wiring harness fixing device of this utility model includes a semi-circular bracket with a semi-circular positioning groove. Its features include: an elastic band and a clamp half fixed to the bottom surface of the semi-circular bracket; the clamp half and the semi-circular positioning groove form a positioning hole for rigid conduits to pass through; the elastic band wraps around the arc-shaped surface of the semi-circular bracket, with one end of the elastic band fixedly connected to one end of the clamp half, and the other end of the elastic band fixedly connected to the other end of the clamp half; and multiple sets of positioning grooves A that mate with the wiring harness are spaced apart on the arc-shaped surface of the semi-circular bracket.

[0007] The semi-circular bracket and clamp half are separate structures that can be connected together by a first fixing bolt and a second fixing bolt. The assembly of the semi-circular bracket and clamp half can be fitted onto the outer wall of a rigid pipe and kept relatively fixed to it. When connecting the semi-circular bracket and clamp half, one end of an elastic band can be clamped between the semi-circular ring and the semi-circular bracket, and the other end of the elastic band can be clamped between the connecting ear A and the semi-circular bracket. Using the elasticity of the elastic band, the wire harness can be fixed in the corresponding positioning slot A, thus securing the wire harness. This method is simple, easy to operate, and convenient to use. Multiple wire harnesses can be sequentially fixed in the positioning slots A on the outer wall of the semi-circular bracket, effectively preventing interference and wear on the pipe or wire harness.

[0008] In any of the above embodiments, preferably, the clamp half includes a semi-circular ring body, one end of which is bent outward to form a connecting ear A, and the other end of which is bent outward to form a connecting ear B. Connecting ear A has an assembly hole A that mates with a first fixing bolt. The first fixing bolt passes through the assembly hole to connect connecting ear A to one end of the semi-circular base. Connecting ear B has an assembly hole B that mates with a second fixing bolt. The second fixing bolt passes through the assembly hole B to connect connecting ear B to one end of the semi-circular base. This facilitates the connection of the semi-circular base and the clamp half, and also makes it easy to clamp one end of the elastic band between connecting ear A and the semi-circular base, and the other end of the elastic band between connecting ear B and the semi-circular base. The connection method is simple and reliable.

[0009] In any of the above embodiments, it is preferred that the elastic band is a flat rubber band, one end of which is clamped between the connecting ear A and the semi-circular retainer, and the other end of which is clamped between the connecting ear B and the semi-circular retainer. The high elasticity of the rubber band allows it to quickly return to its original shape after being stretched. With the help of the elastic band, the wire harness can be fixed in the corresponding positioning slot A without damaging the outer wall of the wire harness.

[0010] In any of the above solutions, it is preferred that the clamp half is made of metal or plastic, and the semi-circular base is made of plastic.

[0011] In any of the above solutions, it is preferred that the positioning slot A is a semi-circular slot.

[0012] In any of the above solutions, it is preferred that the positioning slot A is a U-shaped slot.

The elastic band is pressed against the surface of the arc-shaped surface. The positioning slot B and the positioning slot A form a circular hole for fixing the wire harness. The two sides of the sliding abutment block have guide components for sliding guidance of the sliding abutment block. The positioning slot A is a U-shaped slot. A detachable sliding abutment block is installed in the positioning slot A. The positioning slot B on the sliding abutment block and the positioning slot A form a circular hole for fixing the wire harness. With the elasticity of the elastic band, the sliding abutment block can be fixed in the corresponding positioning slot A without damaging the outer wall of the wire harness, further preventing the wire harness from coming out of the positioning slot A.

[0014] In any of the above embodiments, preferably, the guiding assembly includes sliders disposed on both sides of the sliding abutment block, and a guide groove is provided on the side wall of the positioning slot A to slide in cooperation with the sliders. The upper end of the guide groove extends to the opening of the positioning slot A, and the sliders can slide along the length direction of the guide groove, so that the sliding abutment block slides in the depth direction of the positioning slot A. The structure is simple and reliable, and it is convenient for the sliding abutment block to be installed or removed from the positioning slot A.

[0015] In any of the above embodiments, it is preferred that the semi-circular positioning groove and the inner surface of the semi-circular ring have a rubber protective layer.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The automotive wiring harness fixing device of this utility model can be arranged in multiple sets along the length of the pipeline. The semi-circular bracket and clamp half are separate structures and can be connected together by a first fixing bolt and a second fixing bolt.

When connecting the semi-circular bracket and clamp half, one end of the elastic band can be clamped between the semi-circular ring and the semi-circular bracket, and the other end of the elastic band can be clamped between the connecting ear A and the semi-circular bracket. With the help of the elasticity of the elastic band, the wiring harness can be fixed in the corresponding positioning slot A, thereby fixing the wiring harness. The structure is simple, easy to operate, and convenient to use.

[0017] The automotive wiring harness fixing device of this utility model has multiple sets of wiring harnesses sequentially fixed in positioning slots A on the outer wall of a semi-circular card holder, ensuring the gap between the wiring harness and the surrounding pipelines and effectively avoiding interference and wear of the pipelines or wiring harnesses.

[0018] The automotive wiring harness fixing device of this utility model has an assembly hole A on the connecting ear A that mates with a first fixing bolt. The first fixing bolt passes through the assembly hole and connects one end of the connecting ear A to one end of the semi-circular bracket. The connecting ear B has an assembly hole B that mates with a second fixing bolt. The second fixing bolt passes through the assembly hole B and connects one end of the connecting ear B to one end of the semi-circular bracket. This facilitates the connection of the semi-circular bracket and the clamp half, and also makes it easy to clamp one end of the elastic band between the connecting ear A and the semi-circular bracket, and the other end of the elastic band between the connecting ear B and the semi-circular bracket. The connection method is simple and reliable.

[0019] The automotive wiring harness fixing device of this utility model has a U-shaped positioning slot A. A detachable sliding abutment block is installed in the positioning slot A. The positioning slot B on the sliding abutment block and the positioning slot A form a circular hole for fixing the wiring harness. With the help of the elastic band, the sliding abutment block can be fixed in the corresponding positioning slot A without damaging the outer wall of the wiring harness, further preventing the wiring harness from coming out of the positioning slot A.
