Description

Technical Field

[0001] The utility model relates to a flexible protective device, in particular to a flexible protective device for an automobile wiring harness, and belongs to the technical field of automobile wiring harnesses. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the components that are bundled to form a circuit connection, after the contact terminal (connector) made of copper material is crimped with the wires and cables, and then the insulator is plastic-pressed or metal shell is added on the outside;

[0003] A known authorized invention (publication number: CN219172342U) discloses a flexible protective device for an automobile wiring harness. In view of the problem that the existing wiring harness can be cooled through multiple holes on a first protective plate but cannot be dustproof, and the air contains a large amount of dust, a large amount of dust will be adsorbed on the wiring harness, and the heat dissipation effect of the wiring harness is deteriorated, the following scheme is proposed, which includes a wiring harness body, a protective assembly is provided on the wiring harness body, and the protective assembly includes a first protective plate and a second protective plate. The first protective plate is located at the bottom of the wiring harness body, and the second protective plate is placed on the first protective plate. The second protective plate is provided with a dustproof cloth, and dust in the air can be intercepted to prevent dust from being adsorbed on multiple cables in the wiring harness body. The dustproof cloth can be fixed by a first fixing mechanism, and it is easy to replace. The first protective plate and the second protective plate can be fixed together by a second fixing mechanism for protection, so that the wiring harness body is not messy;

[0004] When the device is in use, dust is prevented by a dustproof cloth, which is bonded by Velcro. However, Velcro is also easy to adhere to dust. Since the stickiness of Velcro comes from the fine fluff on its surface, dust may clog these fluffs, thereby reducing its stickiness, causing the dustproof cloth to fall off and fail to prevent dust normally. Therefore, a flexible protective device for an automotive wiring harness is proposed. Utility Model Content
