Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire harness waterproof sheaths, and more specifically to a wire harness waterproof sheath for automobiles. Background Art
[0002] The automotive wiring harness is the network body of the automotive circuit. The wiring harness is an indispensable system-level component in the entire vehicle. Its function is to provide and distribute power to various systems of the vehicle, and at the same time act as a medium for signal transmission between various components. After installation, the automotive wiring harness is easily affected by external factors, causing the wiring harness to wear, so a sheath is required to protect the wiring harness. However, the existing sheath is prone to cracking when bent, which affects the protection effect of the wiring harness.
[0003] After searching, a Chinese patent with publication number CN220420988U discloses an environmentally friendly, anti-fracture and waterproof wiring harness sheath. The advantage of this structure is that the anti-slip wire block on the connecting end body is used to prevent slipping when disassembling the connecting end body, the inward chamfer on the ring buckle is used to prevent water vapor and rain from entering the interior of the wiring harness, the sheath is used to protect the wiring harness from short circuits and breaks, the gaps between the wiring harnesses are filled with a filling layer to prevent deformation of the wiring harness due to the gaps, the wiring harness is insulated by a rubber insulating layer to prevent signal electromagnetic interference, the waterproof sheath is used to protect the wiring harness from water vapor and rain entering the interior, the shock-absorbing sheath is used to shock-absorb the wiring harness, and the arc-shaped shock-absorbing buffer groove on the shock-absorbing sheath can prevent the wiring harness from being impacted and broken from the inside.
[0004] However, in actual use, since the sheath body is an integrated structure, when one position of the sheath body is damaged, the sheath body needs to be removed from the wire core and replaced as a whole, and it is not convenient to quickly disassemble the sheath body, which not only increases the replacement cost but also affects the protection effect of the wire core.
