Description

Technical Field

[0001] The utility model relates to the technical field of automotive wire harness accessories, in particular to a wire harness bracket fixed by a cable tie. Background Art

[0002] During the automobile manufacturing process, the wire harness, as a key component connecting various electrical components, its layout and fixation are crucial for ensuring the reliability and safety of the vehicle. Most traditional wire harness brackets rely on cable ties to fix the wire harness. Although this method is simple and easy to implement, it is relatively single and the fixing reliability is not good. Due to the complex internal environment of the automobile, the wire harness may be affected by factors such as vibration. If it is not fixed properly, the wire harness may become loose or damaged, thereby affecting the function and safety performance of the vehicle.

[0003] In addition, existing wire harness fixing schemes usually require multiple fixing points to be set on the vehicle body or panel. These fixing points are too dense, which may cause interference between them, especially in places where multiple electrical components need to be installed or wire harnesses cross. In this case, if the distance between the fixing points is insufficient, it may cause the wire harness to be squeezed or wound, further increasing the risk of wire harness wear. Summary of the Invention

[0004] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a wire harness bracket fixed by a cable tie, which solves the problems of poor fixing of the wire harness bracket and interference between fixing points.

[0005] The technical solution of the utility model: It includes a fixing part and a connecting part. A card hole is opened on the connecting part, and a cable tie part is installed at the card hole. The cable tie part and the card hole form a detachable snap connection; the connecting part forms at least two mutually separated split plates, the card holes are correspondingly arranged on each split plate, one side of each split plate is integrally connected to the fixing part, and different angles are formed between each split plate and the fixing part.

[0006] By adopting the above technical solution, through the use of a detachable snap connection method, the cable tie part can be firmly fixed on the card hole of the wire harness bracket, avoiding loosening caused by vibration or other external forces, thereby improving the reliability of wire harness fixing. At the same time, the detachable feature also facilitates the operation during later maintenance or when changing the wire harness layout; by dividing the connecting part into at least two mutually independent split plates, and different angles are formed between these split plates and the fixing part, the fixing points can be reasonably distributed in a limited space, reducing the interference between wire harnesses and between wire harnesses and other components, which helps to reduce wire harness wear. Moreover, the split plates allow users to adjust the position and direction of the wire harness according to actual needs, improving the flexibility of wire harness layout.

[0007] In a possible design, the split plate includes a transition surface and a parallel surface. The transition surface is connected to the fixing part, and the transition surface is bent and connected to the parallel surface. The parallel surfaces of each split plate are arranged parallel to each other, and the card holes are correspondingly arranged on each parallel surface.

[0008] With the above design, the parallel surfaces of each split plate not only ensure sufficient spacing between each cable tie fixing point, avoiding entanglement or extrusion between the wire harnesses, but also can provide a consistent fixing torque, reducing displacement caused by the weight of the wire harness or vehicle movement.

[0009] In a possible design, the cable tie includes a belt body, an elastic chuck, and an insertion body for inserting and fixing the belt body. The insertion body is connected between the belt body and the elastic chuck; both sides of the elastic chuck have arc-shaped elastic arms, and multiple levels of steps are arranged on the elastic arms. The card hole is buckled with the corresponding step to form a snap fit.

[0010] With the above design, during installation, only need to press the elastic arm into the card hole to complete the fixation. During disassembly, only need to apply a certain pressure to make the elastic arm disengage from the card hole. The operation is simple and fast. Moreover, the setting of multiple levels of steps enables the elastic chuck to select a suitable fixing position according to the actual size of the card hole, thus adapting to different sizes of card holes and increasing the applicable range of the cable tie.

[0011] In a possible design, a washer extending outward is integrally provided between the insertion body and the elastic chuck. The washer elastically abuts against the edge of the orifice of the card hole when the cable tie is snapped.

[0012] With the above design, the washer can increase the contact area between the cable tie and the connecting part, prevent the shaking of the wire harness bracket, and play a certain buffering role.

[0013] In a possible design, corner reinforcing ribs are provided at the bending positions between the connecting part and the fixing part and between the transition surface and the parallel surface.

[0014] With the above design, the corner reinforcing ribs can improve the bending resistance of the bending position, improve the fatigue resistance, and keep the existing bending shape of the bending position.

[0015] In a possible design, concave-convex reinforcing ribs are provided on the fixing part.

[0016] With the above design, the overall strength and rigidity of the fixing part are improved by increasing the thickness and shape complexity of the material, thereby reducing the risk of deformation when bearing external loads. Description of the Drawings

[0024] As Figures 1 - 3 shown in the cable tie-fixed wire harness bracket, which includes a fixing part 1 and a connecting part 2. The fixing part 1 and the connecting part 2 are in a sheet structure. The connecting part 2 is provided with a card hole 21 along its thickness direction. A cable tie member 3 is installed at the card hole 21. The cable tie member 3 and the card hole 21 form a detachable snap connection. This detachable snap connection method can adjust the position and direction of the wire harness according to actual needs, facilitating the change of the wire harness layout, and the layout is more flexible. The connecting part 2 forms two mutually split split plates 22. The card hole 21 is arranged on each corresponding split plate 22. One side edge of each split plate 22 is integrally connected to the fixing part 1 respectively. An included angle is formed between each split plate 22 and the fixing part 1 respectively, and the angles of each included angle are not equal. The difference between the angles of two adjacent included angles is more than 30°. In this way, the connecting part 2 is divided into at least two mutually independent split plates 22. Different included angles are formed between the split plates 22 and the fixing part 1, increasing the distance between adjacent cable tie members 3 and reducing the interference between wire harnesses. In addition, when manufacturing the wire harness bracket product, the wire harness bracket with different included angle differences can be processed to select and install a suitable wire harness bracket to fix the wire harness according to the actual situation of the internal space of the vehicle.

[0025] At least one of the split plates 22 includes a transition surface 221 and a parallel surface 222. One side of the transition surface 221 is connected to the fixing part 1. The transition surface 221 and the parallel surface 222 are bent and connected. The parallel surfaces 222 of each split plate 22 are arranged in parallel. The cable tie member 3 on each parallel surface 222 restricts and fixes the wire harness, forming a fixing moment with the same direction, which helps to reduce the displacement caused by the weight of the wire harness or the movement of the vehicle.

[0026] like Figure 4 As shown, the cable tie 3 includes a belt body 31, an elastic clamp 32, and an insertion body 33 for inserting and fixing the belt body 31, and the insertion body 33 is connected between the belt body 31 and the elastic clamp 32. The belt body 31 is a soft belt-like structure, which is sleeved on the wiring harness, and the head of the belt body 31 is inserted into the insertion hole of the insertion body 33 until the wiring harness is effectively constrained. The hook in the insertion hole is buckled with the belt body 31 to fix the position of the belt body 31. The two sides of the elastic clamp 32 have bracket-shaped elastic clamp arms 321, and the elastic clamp arms 321 are provided with multiple steps 322, and the clamp hole 21 is buckled with the corresponding steps 322 to form a buckle fit. During installation, the elastic clamp arm 321 is pressed into the clamp hole 21, and the step 322 is against the corresponding step 322 and does not retreat to complete the fixation; during disassembly, it is only necessary to apply a certain pressure to reduce the spacing between the elastic clamp arms 321 on both sides, so that they can be separated from the clamp hole 21.

[0027] A washer 34 extending outward is integrally provided between the insertion body 33 and the elastic clamp head 32. The washer 34 has a bowl-shaped structure. When the cable tie 3 is buckled, the washer 34 elastically abuts against the plane of the edge of the hole 21, so that the cable tie 3 no longer enters the hole 21 too deeply. In addition, the large area of ​​the washer 34 can prevent the wiring harness bracket from shaking, thereby achieving a limiting effect.

[0028] In order to enhance the structural strength, corner reinforcement ribs 23 are provided at the bending positions between the connecting portion 2 and the fixing portion 1 and between the transition surface 221 and the parallel surface 222, and concave-convex reinforcement ribs 11 are provided on the fixing portion 1. The corner reinforcement ribs 23 are used to improve the bending resistance of the bending position, and the concave-convex reinforcement ribs 11 are used to improve the overall strength and rigidity of the fixing portion 1.
