Wiring harnesses are everywhere in our lives, ranging from alarm clock radios to cars, airplanes, and aircraft carriers. As long as there is a body with a power system, there will be a wiring harness.The wiring harness of new energy vehicles is different from our general wire and cable structure. This is becauseNew energy wire harnessWith high voltage, large current,heat resistant seal, anti-interference characteristics, so the design is different.
In addition to paying attention to the above points for new energy vehicle wiring harnesses, the wiring harness itselfsealThe sexual requirements are also very high, which requires the wiring harness to beConduct rigorous air tightness testing.If the air tightness of the wiring harness is not good, it may cause signal transmission failure, functional equipment failure; or short circuit or fire when exposed to water, or insulation failure and leakage.

Air tightness testing uses compressed air as the medium and fills the compressed air into the inside of the product or mold.Determine whether there is a leak in the product through changes in the internal air pressure of the product.Different test pressures can be adjusted according to different products and waterproof level requirements.

Nowadays, there are various waterproof testing methods for this industry, and different products have a set of applicable methods, but in summary, it is to judge whether their waterproofing is qualified by judging their leakage value and air pressure condition; waterproof testing in the new energy automobile industry and the development of the new energy automobile industry complement each other and develop together, and only good equipment can develop in the long term.
