Dongfeng GX Bumper harness assembly 3724200-C6201 in tocked

The harness features 8-12 independent copper cores (conductor material: oxygen-free copper, cross-sectional area: 0.5-1.5 mm²) to support diverse bumper-mounted electrical functions—including power supply for fog lights, signal transmission for turn signals, and data communication for parking sensors. Each core is insulated with high-temperature-resistant PE material (dielectric strength ≥20 kV/mm) to prevent short circuits between wires. The cores are grouped by function (e.g., power lines in red, signal lines in yellow) and bound with flame-retardant polyester tape, ensuring organized routing within the bumper and easy troubleshooting

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 road salt, while the outer layer is a wear-resistant nylon braid (abrasion resistance ≥500 cycles) that shields against friction from bumper metal edges or road debris. It withstands extreme temperatures (-40°C to 100°C) and meets IP67 waterproof standards—connectors are sealed with silicone O-rings, and cable entry points use rubber grommets to block rainwater and dust. This design ensures reliable performance even in harsh conditions like heavy rain, snow, or off-road driving

The assembly is equipped with 10-15 high-strength nylon mounting clips (with tensile strength ≥60 N) that match the Dongfeng GX bumper’s pre-installed mounting points. The clips feature a snap-on design for quick attachment to the bumper’s inner reinforcement, 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., "Left Fog Light," "Right Turn Signal") corresponding to the bumper’s component locations, reducing installation time by 35% compared to unmarked harnesses. No additional drilling is required, ensuring the bumper’s structural integrity

The harness integrates twisted-pair shielding for sensor signal lines (shielding layer: tinned copper mesh, coverage rate ≥90%) to reduce electromagnetic interference (EMI) from the engine or other front-end electrical components. This ensures accurate signal transmission—voltage drop is controlled below 0.1V per meter, and data delay for parking sensors is ≤2ms, critical for reliable obstacle detection. The power lines for high-current components (e.g., fog lights) are designed with overcurrent protection fuses (rated current 10-15A), preventing 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
