[0039] The technical solutions shown in the present application are described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0040] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a wire harness fastening structure, including a washer 100 , an extension piece 200 , a fastener 300 and a grounding piece 400 .

[0042] The grounding member 400 has a limiting portion 410 , which is configured to abut against the extending member 200 when the fastener 300 is screwed to connect with the grounding member 400 , so as to limit the washer 100 and the extending member 200 from rotating with the fastener 300 .

[0043] Exemplarily, the extension piece 200 is arranged in a long strip shape, the extension piece 200 is connected to one side of the gasket 100, the extension piece 200 and the gasket 100 are on the same horizontal plane, and the extension line of the extension piece 200 along its length direction is arranged collinearly with the center of the gasket 100.

[0044] Exemplarily, when the wire harness is fixed on the gasket 100 , the wire harness is located between the fastener 300 and the gasket 100 , and the fastener 300 compresses and fixes the wire harness on the gasket 100 .

[0045] Exemplarily, the gasket 100 abuts against the grounding member 400 to ground the gasket 100 , thereby placing the wiring harness in a grounded state after installation.

[0046] Exemplarily, the fastener 300 may be a cross screw, so as to fix the washer 100 on the grounding member 400 .

[0047] Exemplarily, the limiting portion 410 can be a limiting pin, which is detachably provided on the grounding member 400.

[0048] By adopting the above technical solution, by setting the washer 100, the extension piece 200, the fastener 300 and the grounding piece 400, the wiring harness is connected to the washer 100 through the fastener 300, and the washer 100 is connected to the grounding piece 400 through the fastener 300, so as to achieve the fixing of the wiring harness on the abutment piece, and the grounding piece 400 has a limiting portion 410, the extension piece 200 is connected to the washer 100, and the extension piece 200 abuts against the limiting portion 410. When the fastener 300 is rotated, the fastener 300 will give the washer 100 and the extension piece 200 a force to rotate with the fastener 300. At this time, the extension piece 200 abuts against the limiting portion 410, thereby limiting the washer 100 and the extension piece 200 from rotating with the fastener 300, thereby preventing the wiring harness from rotating with the fastener 300.

[0049] In some embodiments provided in this application, for example, please refer to Figure 1 and Figure 2 The grounding member 400 is a sheet metal member having a sheet metal protrusion thereon, and the sheet metal protrusion forms a limiting portion 410 .

[0052] In some embodiments provided in the present application, the sheet metal protrusion is exemplarily a rupture portion formed by punching and rupture.

[0053] Among them, when the washer 100 is fixed on the grounding member 400, the washer 100 is first placed on the grounding member 400, the position of the extension member 200 is determined, and then according to the rotation direction of the fastener 300 and the position of the extension member 200, the position of the sheet metal protrusion is marked on the grounding member 400, and then the sheet metal is punched using a stamping part until the sheet metal is broken. At this time, a rupture portion is formed on the sheet metal, and the rupture portion is raised relative to the surface of the sheet metal, so that the extension member 200 can abut against the rupture portion.

[0054] Exemplarily, the stamped part may be a stamped rod or a screw.

[0055] By adopting the above technical solution, the ruptured part formed by the sheet metal protrusion being punched and broken by the stamping part can enable the installer to process the sheet metal part according to the actual situation, thereby improving the convenience of fixing the wiring harness, and eliminating the need to customize the sheet metal part, thereby reducing the production cost of the wiring harness fastening structure.

[0056] In some embodiments provided in the present application, the fastener 300 is exemplarily a screw or a bolt.

[0057] By adopting the above technical solution and setting the fastener 300 as a screw or a bolt, it is convenient for the installer to use the fastener 300 to fix the washer 100 and the wiring harness on the grounding member 400 .

[0058] In some embodiments provided in this application, for example, please refer to Figure 1 and Figure 2 The extension piece 200 includes an extension plate 210 , and the extension plate 210 is integrally formed with the gasket 100 .

[0059] The gasket 100 is formed by punching a plate through a punching machine.

[0060] For example, when manufacturing the gasket 100 and the extension plate 210 , a punching machine is used to punch a plate material according to the shapes of the gasket 100 and the extension plate 210 to form the extension plate 210 and the gasket 100 that are integrally formed.

[0061] By adopting the above technical solution, the production cost of the gasket 100 and the extension piece 200 is reduced.

[0067] The diameter of the circular ring formed by the two semicircular rings is larger than the diameter of the wiring harness. After the wiring harness is inserted into the circular ring, the two semicircular rings need to be squeezed so that the two semicircular rings tighten the wiring harness.

[0068] By adopting the above technical solution and providing two semicircular rings, it is convenient to fix the wire harness on the extension piece 200 .

[0069] In some embodiments provided in the present application, illustratively, the semicircular ring is integrally formed with the extension plate 210 .

[0070] For example, when the gasket 100 and the extension plate 210 are produced, bending portions are reserved on both sides of the extension plate 210, and then the bending portions are circularly bent to form a semicircular ring.

[0071] By adopting the above technical solution, the production cost of the connecting part 220 is reduced.
