The waterproof performance of a car is an important factor affecting the comfort and reliability of the car. The quality of its design directly affects the intuitive experience of consumers.In daily life, vehicles are exposed to water impact in many situations, such as driving in rain or snow, driving on watery roads, washing cars, etc. Especially the current urban waterlogging has brought a more severe test to the waterproof performance of cars.

Product to be tested: Automotive controller wires

As the nervous system that connects automobile electrical appliances, the automobile wiring harness carries the task of transmitting current and signals. Therefore, once the waterproofing of the wiring harness fails, it may cause the electrical function to fail at the least, or cause disasters such as short circuits and burning of the car.Therefore, the waterproof performance design of the wiring harness is particularly important in the design of the entire vehicle electrical system.

The customer requested that the wires for the car controller be madeIP68Waterproof levelFor testing, Hiraysi uses the following equipment and methods for its products:

Automotive controller wireAir tightness and waterproof testing equipment

Equipment used: HiraysHCClassic series positive and negative pressure air tightness testing equipment

Testing method: Direct testing method, by sealing the joints on both sides of the connector, then directly inflating, and testing the air pressure changes in the sealed space to determine the sealing performance of the joints on both sides and the wires.The test pressure is100KPA ，The leakage limit does not exceed50pa

Using this method,Not up to pressure100KPA，Or the leakage limit exceeds50PAproducts can be quickly detected.forNGproduct, which can be detected through subsequent testingNGWhich end of the wire is the leakage at?。

The waterproof design of the entire vehicle is a very complex and important project.The watertightness of the wiring harness is an important component of electrical system reliability.The wiring harness is a key component of the car, and its basic function is to carry current and signals.Poor waterproof performance directly affects the realization of basic functions.So the harnessWaterproof testing is very important.
