The function of the automobile distribution box is to ensure the transmission of power and electrical energy in the entire vehicle system, and is a bridge for power supply and signal transmission between the power battery and various high-voltage equipment.And it can detect insulation faults, open circuit faults, ground faults and high-voltage faults of the entire high-voltage system at any time.

Automobile distribution box housingis very important，It plays a role in protecting the components in the cabinet.Generally, the car distribution box housing needs to be waterproof to prevent some bad weather.When the automobile distribution box shell is used in harsh environments, it can easily berainwater infiltration, resulting in internal damage, which is not what we want to see. Only distribution boxes that can be used for a long time are what we need.

The protection level requirements of automobile distribution box shells are relatively high and need to reachIP68, let’s take a look at the case of Hirays Technology’s air tightness testing for automobile distribution box shells. The test part is inside the shell, mainly to test whether the die-casting parts have hourglasses. The following are the equipment and solutions used:

Equipment used:Hai RuisiHCAir tightness testing equipment

Solution: Use direct testing method to test pressure200KPA, inflation time13S, stabilization time30S, test time60S.Design the test mold and tooling according to the structure of the product, place the product on the mold as required, press the start button and push the upper mold downward to seal all holes and form a sealed cavity inside the product.The instrument inflates, stabilizes, and tests the interior of the product, and detects the sealing condition of the product by monitoring changes in the total internal air pressure.

As an important part of the automobile, the automobile distribution box housing has very strict quality requirements. It is very necessary to use Hirays air tightness testing equipment for testing. The detection results are accurate and fast, and it has been favored by the majority of automobile distribution box housing manufacturers.
