Description

Technical Field

[0001] The utility model relates to the technical field of wire harness accessories, in particular to a wire harness bracket convenient for assembly. Background Art

[0002] In modern automotive design and manufacturing, the complexity and density of in-vehicle wiring systems are increasing day by day. To ensure the functionality and safety of these circuits, prevent chaos and entanglement between circuits, and at the same time reduce the risk of wear and thermal damage caused by friction, wire harness brackets, as important fixing devices, are widely used.

[0003] Although traditional fixing methods can provide stable support, due to their rigid design, the movement space of the wire harness during actual use is limited, which easily causes excessive wear; in addition, the preset positions of such fixings often lack the necessary flexibility and are difficult to adapt to the constantly changing actual needs during vehicle operation. There is also an elastic wire sleeve similar to that in a Chinese patent: a multi-purpose pipeline wire harness fixing bracket (CN212543294U), which uses the elasticity of a spring to buffer external pressure and reduce the damage degree of the wire harness. However, this solution often leads to an increase in production costs due to its structural complexity, and the installation process is relatively cumbersome. For the automotive industry that requires a large number of wire harness brackets, this undoubtedly increases the assembly difficulty and cost burden. Summary of the Invention

[0004] The purpose of the utility model: To overcome the defects of the prior art, the utility model provides a wire harness bracket convenient for assembly that can not only effectively fix the wire harness, but also allow appropriate movement space, and at the same time has flexible installation characteristics.

[0005] The technical solution of the utility model: It includes a bracket body and an elastic wire sleeve. The bracket body includes a number of socket parts, and the socket parts form semi-circular grooves. The elastic wire sleeve is installed in the corresponding socket parts and is adapted to the grooves; a wire harness is passed through the elastic wire sleeve to expand the elastic wire sleeve so that the elastic wire sleeve is tightly fitted with the socket parts.

[0006] By adopting the above technical solution, by passing the wire harness through the elastic wire sleeve and using the expansion effect of the elastic wire sleeve, not only can the wire harness be firmly fixed, but also the elastic effect of the elastic wire sleeve can absorb vibrations and impact forces, reducing the wear of the wire harness caused by vehicle movement; in addition, there are a number of socket parts, and appropriate fixing points can be selected according to actual needs, thus improving the flexibility of the installation position and facilitating adjustment according to specific situations; compared with traditional fixing methods or complex elastic wire sleeve structures, the elastic wire sleeve of the utility model is directly snapped into the socket part from the notch of the groove, with a simpler structure and easier assembly, effectively controlling production costs, and can be applied to the entire automotive wiring system.

[0007] In a possible design, the elastic wire sleeve is in the shape of a hollow cylinder, and a longitudinal through-opening is provided at the outer peripheral position of the elastic wire sleeve, and the longitudinal through-opening is arranged along the axial direction of the elastic wire sleeve.

[0008] With the above design, due to the existence of the longitudinal through-opening, the elastic wire sleeve can adapt to wire harnesses of different diameters through its own elasticity and the deformation at the opening, increasing the applicable range and enabling a single wire sleeve to match wire harnesses of multiple specifications.

[0009] In a possible design, convex flanges are respectively provided on the outer peripheries at both ends in the axial direction of the elastic wire sleeve, and the flanges abut against the axial ends of the socket part to form a limit.

[0010] With the above design, the flanges can effectively prevent the elastic wire sleeve from slipping out of the socket part. Even when the vehicle encounters bumps or vibrations during operation, the stability of the wire harness fixing device can be ensured. Moreover, the flanges contribute to quick positioning, enabling the assembly worker to complete the fixing of the wire harness more quickly.

[0011] In a possible design, the socket parts are arranged at intervals, and an elastic connecting arm is connected between adjacent socket parts.

[0012] With the above design, the elastic connecting arm can provide a certain degree of flexibility between the socket parts. In this way, even in places with limited space or where bending is required, the wire harness can bend naturally along with the deformation of the elastic connecting arm, enhancing the adaptability of the overall bracket to different installation environments.

[0013] In a possible design, the socket part is in the form of a semi-circular sheet structure.

[0014] With the above design, the socket part in the form of a sheet structure is easy to process and manufacture, which is conducive to mass production. Moreover, its semi-circular shape endows it with a certain degree of elasticity, enabling it to better cooperate with the elastic wire sleeve and adding an elastic binding force to the elastic wire sleeve.

[0015] In a possible design, the bracket body further includes a fixing part, and a clamping arm is integrally provided on the fixing part, and the clamping arm is perpendicular to the fixing part.

[0016] With the above design, the clamping arm enables the bracket to be directly snapped into the predetermined position, realizing quick positioning, ensuring that the bracket can be accurately installed at the designated position, and improving the assembly efficiency.

[0022] As Figures 1 - 3 shown, a wire harness bracket facilitating assembly includes a bracket body 1 and an elastic wire sleeve 2. The bracket body 1 is integrally in a sheet structure and is made of a metal material with a certain elasticity, and can be processed and formed by a stamping device. The bracket body 1 includes a plurality of socket parts 11, and a semi-circular groove 12 is formed in each socket part 11. The elastic wire sleeve 2 is installed and snapped into the corresponding socket part 11 from the notch of the groove 12 and is adapted to the groove 12. During installation, first pass the pre-fixed wire harness through the elastic wire sleeve 2. The wire harness will expand the elastic wire sleeve 2, or due to the elasticity of the elastic wire sleeve 2 itself. Then, install the elastic wire sleeve 2 into the groove 12 at the corresponding position. The elastic wire sleeve 2 is tightly pressed against the groove wall of the groove 12, so that the elastic wire sleeve 2 is tightly fitted with the socket part 11 to form a fixation. In order to ensure the installation stability of the elastic wire sleeve 2, the notch direction of the groove 12 is facing the preset fixing position of the bracket body 1, so that the bracket body 1 forms an enclosed shape.

[0023] The elastic wire sleeve 2 is in a hollow cylindrical shape, so as to fit the shape of the wire harness. A longitudinal through-hole 21 is provided at the outer peripheral position of the elastic wire sleeve 2. The longitudinal through-hole 21 is arranged along the axial direction of the elastic wire sleeve 2 so as to penetrate the axial direction of the entire outer peripheral wall of the elastic wire sleeve 2. When the wire harness passes through the longitudinal through-hole 21 and enters the inside of the elastic wire sleeve 2, the elastic wire sleeve 2 will closely fit on the surface of the wire harness under the action of its own elastic force, forming a firm fixing structure to prevent the wire harness from sliding or falling off. Due to the existence of the through-hole, the elastic wire sleeve 2 can increase the applicable range for different wire diameters through its own elasticity and by using the gap of the longitudinal through-hole 21, and the expansion and tightening range of the elastic wire sleeve 2 is wider.

[0024] Ring-shaped flanges 22 are respectively provided on the outer peripheries at both ends in the axial direction of the elastic wire sleeve 2. The flanges abut against the axial ends of the socket part 11 to form a limit, thereby preventing the elastic wire sleeve 2 from disengaging from the socket part 11 in the height direction, especially when encountering bumps or vibrations during vehicle operation, and improving the stability of the wire harness fixation.

[0025] Each socket part 11 is arranged linearly or at intervals in a certain regular manner, and an elastic connecting arm 13 is connected between adjacent socket parts 11. The elastic connecting arm 13 is arc-shaped. The connection of the elastic connecting arm 13 makes the overall structure more flexible, can adjust the position and direction of the wire harness according to actual needs, improves the flexibility of the arrangement, and is convenient for adjustment according to different application scenarios.

[0026] The socket part 11 has a semi-circular arc-shaped sheet structure. The socket part 11 with a sheet structure is easy to process and manufacture, is conducive to mass production, and its semi-circular shape gives it a certain elasticity, can better cooperate with the elastic wire sleeve 2, and adds an elastic binding force to the elastic wire sleeve 2.

[0027] The bracket body 1 further includes a fixing part 14. The fixing part 14 is integrally provided with a clamping arm 15, and the clamping arm 15 is perpendicular to the fixing part 14. The clamping arm 15 enables the bracket body 1 to be firmly fixed in the installation position, and can maintain stability even when encountering bumps or vibrations during vehicle driving, preventing the wire harness bracket from shifting.
