Description

Technical Field

[0001] This utility model belongs to the field of wire harness technology, and in particular relates to a kitchen appliance oil fume resistant wire harness. Background Technology

[0002] "Smoke detector harness" refers to a wire harness or cable assembly specifically used to connect smoke detectors (smoke detectors) to other fire protection equipment or system hosts. Its core function is to provide power supply and signal transmission channels for smoke detectors. In practical application scenarios, smoke detectors are mostly installed in high-temperature and oily fume environments such as kitchens, restaurants, and hotel kitchens.

[0003] Currently, existing oil fume-resistant wire harnesses generally only use oil-resistant materials for the outer sheath. However, after long-term exposure to high-temperature oil fume environments, the organic solvent components in the oil will gradually penetrate the molecular gaps of the outer sheath and cause a swelling reaction with the internal shielding / insulation layer of the wire harness, leading to material embrittlement and cracking. Oil may also adhere to the surface of the wire harness conductor or shielding layer, causing abnormal resistance fluctuations, resulting in signal distortion, false alarms, or communication interruptions.

[0004] To address the aforementioned issues, this application proposes a kitchen appliance oil fume resistant wiring harness. Utility Model Content

[0005] The purpose of this utility model is to provide a kitchen appliance oil fume resistant wiring harness, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a kitchen appliance oil fume resistant wiring harness, comprising a conductor and an outer sheath, and multiple spiral film layers evenly distributed on the outer surface of the outer sheath. The spiral film layers are formed by spirally winding a soft film around the outer sheath, with adjacent layers of each spiral film layer overlapping each other. The spiral film layers are used to block oil stains. Multiple sets of fixing rings are included, each set of fixing rings comprising two fixing blocks wound around the ends of the same spiral film layer. The inner wall of the fixing block is fixedly connected to the outer sheath, and the outer wall of the fixing block is fixed with a snap ring wrapped by the spiral film layer. A fixing component is provided outside the fixing block, which is used to snap the snap ring to facilitate the removal of the spiral film layer.

[0008] Furthermore, the fixing component includes a first semi-ring and a second semi-ring. The inner walls of the first and second semi-rings are provided with arc-shaped grooves that cooperate with the snap ring. One end of the first semi-ring is hinged to one end of the second semi-ring. The other ends of the first and second semi-rings are both fixed with fixing plates, and the fixing plates are provided with fixing holes.

[0009] Furthermore, a heat dissipation ring is fixed between adjacent fixed ring groups and is fixed to the outer wall of the outer protective layer, and the two sides of the heat dissipation ring are respectively fixed to the fixed block.

[0010] Furthermore, the outer periphery of the conductor is covered with an insulating layer, and the outer periphery of the insulating layer is covered with an inner sheath, the inner sheath being disposed within the wrapping layer, and the wrapping layer and the inner sheath being filled with a filler layer.

[0011] Furthermore, the inner wall of the outer protective layer is fixedly connected to the armor layer, and the inner wall of the armor layer is fixedly provided with a shielding layer, the inner wall of the shielding layer being fixedly connected to the outer wall of the wrapping layer.

[0012] Furthermore, the spiral film layer is made of food-grade silicone rubber.

[0013] Furthermore, the outer protective layer is made of PVC, and the outer wall of the outer protective layer is coated with an oleophobic coating.

[0014] This utility model has the following beneficial effects:

[0015] This invention uses a spiral film layer to block oil stains. The spiral film layer forms a continuous physical barrier without dead angles through the spiral winding structure of the soft film and the overlapping design between adjacent layers. This structure can effectively prevent oil fume particles from penetrating into the wire harness.

[0016] This invention enables the detachable installation of the spiral film layer by using a fixing component and a mechanical locking ring. When the barrier performance of the spiral film layer decreases due to long-term oil accumulation, a single section of the film layer can be independently disassembled and replaced, preventing oil residue from continuously adhering and affecting the protective performance, while also reducing the overall maintenance cost of the wiring harness.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figure 1 - Figure 3 As shown, this utility model is a kitchen appliance oil fume resistant wire harness, including a conductor 1 and an outer sheath 6, and multiple spiral film layers 10 evenly distributed on the outer surface of the outer sheath 6. The spiral film layer 10 is formed by spirally winding a soft film around the outer sheath 6. The adjacent layers of each spiral film layer 10 overlap each other. The spiral film layer 10 is used to block oil stains. Multiple sets of fixing rings 8 are provided. Each set of fixing rings 8 includes two fixing blocks 9 wound around the ends of the same spiral film layer 10. The inner wall of the fixing block 9 is fixed to the outer sheath 6, and the outer wall of the fixing block 9 is fixed with a snap ring 901 wrapped by the spiral film layer 10. The fixing block 9 is provided with a fixing component 11, which is used to snap the snap ring 901 to facilitate the removal of the spiral film layer 10.

[0027] This embodiment provides a kitchen appliance oil fume resistant wire harness. The spiral film layer 10 is wound around the outer sheath 6 and adheres to the outer wall of the outer sheath 6. The adjacent layers of the spiral film layer 10 overlap by 1-2 mm to avoid gaps between adjacent layers. The spiral film layer 10 isolates the outer sheath 6 from the outside environment, preventing oil stains from directly contacting the outer sheath 6 and improving the oil resistance of the wire harness. After the two ends of the spiral film layer 10 are wound around the fixing block 9 and wrapped with the snap ring 901, the fixing component 11 is snapped into the snap ring 901 to achieve reliable fixation of the spiral film layer 10. Subsequently, the fixing component 11 can be removed to replace the spiral film layer 10.

[0028] The fixing component 11 includes a first semi-ring 1101 and a second semi-ring 1102. The inner walls of both the first and second semi-rings have arc-shaped grooves 1104 that mate with the snap-fit ​​ring 901. One end of the first semi-ring 1101 is hinged to one end of the second semi-ring 1102. The other ends of both the first and second semi-rings are fixed with fixing plates 1103. The fixing plate 1103, which has a fixing hole, is fixed to the first half-ring 1101 and the second half-ring 1102 by bolts. During installation, after the spiral film layer 10 wraps around the snap ring 901, the first half-ring 1101 and the second half-ring 1102 are fastened to the end of the spiral film layer 10, so that the snap ring 901 is embedded in the arc groove 1104. Then, the fixing plate 1103 is fixed together by bolts to achieve reliable fixing of the spiral film layer 10.

[0029] Among them, a heat dissipation ring 7 is fixed between adjacent fixed ring groups 8 and is fixed to the outer wall of the outer sheath 6. The two sides of the heat dissipation ring 7 are respectively fixed to the fixed block 9. The heat dissipation ring 7 can be an aluminum ring plate, which can quickly conduct the heat generated by the wire harness to the outside and avoid the wire harness from aging due to excessive temperature.

[0030] The conductor 1 is covered with an insulating layer 101 on its outer periphery, and an inner sheath 102 is covered on the outer periphery of the insulating layer 101. The inner sheath 102 is disposed inside the wrapping layer 3, and the wrapping layer 3 and the inner sheath 102 are filled with a filler layer 2. The insulating layer 101 can be made of PVC insulating material, the inner sheath 102 can be made of nitrile rubber, and the filler layer 2 is made of glass fiber filler material.

[0031] The inner wall of the outer sheath 6 is fixedly connected to the armor layer 5, and the inner wall of the armor layer 5 is fixedly provided with a shielding layer 4. The inner wall of the shielding layer 4 is fixedly connected to the outer wall of the wrapping layer 3. The shielding layer 4 can be a copper foil shielding layer to isolate external electromagnetic interference. The armor layer 5 can be steel strip armor, which can improve the wire harness's resistance to compression.

[0032] The spiral film layer 10 is made of food-grade silicone rubber, which has outstanding oil resistance and good mechanical strength.

[0033] The outer protective layer 6 is made of PVC and has an oleophobic coating on its outer wall. The oleophobic coating is a polytetrafluoroethylene oleophobic coating, which reduces the probability of oil stains adhering and further improves the oil stain prevention effect.

[0034] Understandably, this utility model not only isolates the outer sheath 6 from external oil stains and improves the oil resistance of the wire harness, but also allows for the disassembly and replacement of the spiral film layer 10, making maintenance simple and convenient.

[0035] A specific application of the operation process in this embodiment is as follows: when the wire harness is in a kitchen oil fume environment, the overlapping structure of the spiral film layer 10 blocks the penetration of oil stains and improves the oil resistance of the wire harness. The oleophobic coating of the outer sheath 6 further improves the oil resistance of the wire harness. The internal multi-layer protective structure ensures the insulation, anti-interference and mechanical strength of the conductor 1 in complex environments. The heat dissipation ring 7 can accelerate heat dissipation and prevent the wire harness from aging rapidly due to excessive temperature.
