1. Automotive Wiring Harness: The Lifeblood of Electrical Systems
The automotive wiring harness is a vital component of a vehicle's internal electrical system. Comprising main and branch wires encased in insulation, it connects elements like electronic control units, lights, door locks, and audio systems, ensuring accurate current and signal transmission. Despite varying designs across brands, all adhere to strict manufacturer norms for withstanding harsh conditions like high temperatures and vibrations, preventing wire breakage or short circuits. Regular maintenance is crucial for driving safety.
2. Waterproof Testing: An Essential Safeguard for Wiring Harnesses
During car assembly, rigorous testing, especially airtight waterproof testing, is vital. Cars face severe weather like heavy rain, sleet, and hail. Poor waterproofing can cause wire short circuits or breaks, disrupting electronic systems and endangering occupants. Thus, strict waterproof testing during production ensures effective water resistance in real-world use.
3. Airtightness Detection: From Water Immersion to Gas Testing
Traditional water immersion leak detection, observing harnesses in water, has drawbacks like human error and low efficiency. Now, gas testing using airtightness detectors or helium mass spectrometers is mainstream. By placing harnesses in high-pressure gas environments, it swiftly and accurately assesses airtightness. Compared to water immersion, gas testing boosts efficiency, testing 80-100 workpieces per hour (including handling time), and supports multi-channel detection for doubled capacity, meeting mass production needs.
4. Enhancing Airtightness: Materials and Design Matter
A harness's airtightness depends not only on testing but also on shell materials and design. Thicker shells, seals, or tapes improve airtightness. High-quality materials like rubber or plastic offer better protection than inferior ones. Proper design and quality materials ensure stable performance in high-pressure gas environments.
