Dongfeng GX Frame harness assembly 3724580-H06D1

The harness features 20-30 independent copper cores (conductor material: oxygen-free copper, cross-sectional area: 0.3-2.5 mm²) to support diverse electrical functions—including power supply for frame-mounted sensors, signal transmission for brake systems, and control signals for auxiliary lights. Each core is insulated with high-temperature-resistant PE material (dielectric strength ≥18 kV/mm) to prevent short circuits between wires. The cores are grouped by function (e.g., power lines in red, signal lines in blue) and bound with flame-retardant polyester tape, ensuring organized routing and easy maintenance

The harness is wrapped in a double-layer protective sleeve: the inner layer is a flexible PVC tube (thickness 1.2-1.5 mm) resistant to oil, acid, and alkali, while the outer layer is a woven glass fiber sleeve with flame-retardant rating V-0 (meeting UL94 standards). This design withstands extreme temperatures (-40°C to 120°C), prevents abrasion from frame metal edges or road debris, and resists corrosion from road salt, rainwater, and dust. The connectors are IP68-rated, with silicone O-rings sealing all gaps—ensuring reliable performance even in off-road, rainy, or high-humidity environments

The assembly is equipped with 30-40 high-strength nylon mounting clips (with tensile strength ≥80 N) that match the Dongfeng GX frame’s pre-installed mounting points. The clips feature a snap-on design for quick attachment to the frame, and their rubber gaskets buffer vibration (frequency 10-500 Hz) to avoid harness displacement during driving. Additionally, the harness is pre-marked with position labels (e.g., "Front Sensor," "Rear Brake Light") corresponding to the frame’s component locations, reducing installation time by 40% compared to unmarked harnesses. No additional drilling is required, ensuring the frame’s structural integrity

The harness integrates twisted-pair shielding for signal lines (shielding layer: tinned copper mesh, coverage rate ≥90%) to reduce electromagnetic interference (EMI) from the engine or other electrical components. This ensures signal transmission accuracy—voltage drop is controlled below 0.15V per meter, and signal delay is ≤5ms, critical for sensitive components like ABS sensors. The power lines are designed with overcurrent protection fuses (rated current 5-20A, matching each circuit’s load) to prevent damage from short circuits. The entire harness undergoes a 100% continuity and insulation resistance test (≥100 MΩ at 500V DC) before leaving the factory, ensuring zero defects
