The rapid development of the global new energy vehicle industry has promoted the continued expansion of the automotive connector market.According to Bishop&& Associate, the global market size of automotive connectors in 2020 will be approximately US$14.146 billion, growing by 20.5% to US$17.047 billion in 2021.
In recent years, with the development of new energy vehicles in the country, connectors have gradually separated from traditional high-voltage and high-current and traditional low-voltage automotive connectors.Compared with traditional high-voltage and high-current connectors, the working conditions of new energy vehicle connectors are more complex and changeable, and the increase in voltage level (currently the voltage of mainstream systems is higher than 300VDC) increases the risk of human body being injured by electric shock and requires higher safety requirements for connectors; therefore, compared with traditional low-voltage plug-ins, the insulation and protection requirements of the product have increased.
In order to ensure the reliability of the connection and driving safety, it is necessary toNew energy connector air tightness testingprocess.
Testing instrument: HC classic seriesAir tightness detector
According to the shape of the product to be tested and customer needs, the differential pressure detection method is determined and the matching molds and tooling are customized.
Intake air quantitatively for 5 seconds, inflate to 50 kPa, and enter the pressure stabilization stage after 10 seconds, lasting for 10 seconds, and test for 5 seconds. During this period, if the leakage value does not exceed 50 Pa, it means that the air tightness of the product to be tested is qualified.
