In the past two years, the development of new energy vehicles has increased, with production and sales reaching new highs.
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.

The voltage level of new energy connectors in mainstream systems is generally higher than 300V DC, which increases the risk of electric shock injury to the human body, so the connectors are required to have high insulation.
This requires the connector to undergo a waterproof performance test before leaving the factory, which is what we callAir tightness testing。
The case we want to share today isNew energy connector air tightness testing。
After we communicate with our customers and based on their needs, we recommend using:
Hirays HC classic series air tightness detector and customized molds and tooling.
Detection method: Using the direct voltage detection method, the mold and tooling are first customized according to the structure of the new energy connector, customer needs, and the experience of our engineers.

When testing, put the product to be tested into the mold, select the set program, and press the start button.
Inlet pressure is 50Kpa, air intake time is 10s, pressure stabilization is 10s, test time is 5s, and deflation time is 2s.
If the leakage value does not exceed 30pa, it means that the new energy connector has passed the waterproof test, and the test result will also show OK.
