Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical wires for automobiles, specifically to a flame-retardant low-voltage electrical wire for automobiles. Background Technology

[0002] Low-voltage electrical wiring for automobiles refers to wiring harnesses with a nominal voltage of less than 50V used in automotive electrical systems, including single wires. These wiring harnesses are responsible for connecting various electrical and electronic devices in the vehicle to enable the transmission of signals and energy. They are typically composed of multi-core copper wires, including a metallic conductor and an insulating outer layer.

[0003] The applicant discovered through a search that a Chinese patent, "Structure of Low-Voltage Wire for Automobiles," with publication number "CN220553315U," is disclosed. This structure, belonging to the field of wire and cable manufacturing technology, includes a wire sheath. A polystyrene foam block is fixedly connected to the inner side of the sheath, and dried limestone particles are fixedly connected inside the polystyrene foam block. A low-smoke halogen-free flame-retardant strip is placed between the two sets of polystyrene foam blocks. This application utilizes the low-smoke halogen-free flame-retardant strip in conjunction with the polystyrene foam block to provide cushioning in the event of external impact or pressure on the wire sheath, further preventing damage to the internal conductive wires. Simultaneously, the low-smoke halogen-free flame-retardant strip can also shrink, securing the low-voltage wire into the required through-hole. The reaction force of the low-smoke halogen-free flame-retardant strip provides internal support. The dried limestone particles absorb moisture, preventing water from seeping into the wire sheath. The insulating layer provides insulation.

[0004] Although the above-mentioned device can absorb moisture and isolate external flames, it is still prone to spontaneous combustion when the internal temperature is too high, causing safety hazards. At the same time, the internal support frame is strong and can easily damage the wires when they are squeezed. Utility Model Content

[0012] Preferably, the heat dissipation components are provided in eight groups, and the eight groups of heat dissipation components are equidistantly arranged on the wire sheath. The low-smoke halogen-free flame retardant strips and dry lime blocks are provided in eight groups, and the eight groups of low-smoke halogen-free flame retardant strips and dry lime blocks are equidistantly arranged on the inner side of the wire sheath.

[0013] Preferably, the wire body assembly is provided in four groups, and the four groups of wire body assemblies are equidistantly arranged on the support assembly.

[0014] This utility model has the following advantages:

[0016] Meanwhile, the aforementioned device, by incorporating rubber plates, allows the honeycomb holes on rubber support plates one and two to deform under pressure when the wires are squeezed or compressed during use. This reduces the damage to the top structure caused by rubber support plates one and two, while also protecting and supporting the internal wire assembly. Attached Figure Description
