Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile parts detection equipment, in particular to an ABS electronic control unit housing assembly leakage test equipment. Background Art
[0002] Anti-lock braking system, referred to as ABS, is a high-tech braking system developed based on the adhesion characteristics between automobile tires and the road surface. It starts from the requirement of preventing the vehicle from locking during braking (locking refers to the phenomenon that the wheels have stopped rotating during braking, but the vehicle still slides on the road due to inertia), prevents the unstable working conditions described in the previous paragraph during emergency braking, and achieves the active safety device for the purpose of improving driving stability and directional controllability. The electronic control unit housing assembly is an important component of the ABS ECU, and the PCBA is an important component inside the ABS ECU. The PCBA will fail if there is water vapor erosion, so the leakage test of the electronic control unit housing assembly is more important. The current common leakage test method is as follows: The electronic control unit (ABS ECU) needs to install the PBCA, and the sealing back cover must be installed with glue before the electronic control unit can be tested for leakage through the test tool. If the leakage test fails, the PBCA will be scrapped, resulting in a great loss of cost. Therefore, the electronic control unit housing assembly must be leak tested before the PCBA is installed, and because the electronic control unit housing assembly has different appearances. Therefore, the utility model proposes an ABS electronic control unit housing assembly leakage test device to solve the deficiencies and shortcomings of the prior art. Utility Model Content
