Problems solved by technology
Therefore, when the DUT fails the waterproof test, moisture will penetrate into the DUT and cause damage
Moreover, this method is only suitable for a small amount of testing in the initial R&D stage or product random testing during mass production, so it cannot be guaranteed that every product has the same waterproof effect as the sampling test piece

The invention discloses a vacuum waterproof testing device which comprises a testing machine body, a testing cavity, a vacuum pump, a standard pressure cavity, electromagnetic valves and a control panel. The testing cavity, the vacuum pump, the standard pressure cavity and the electromagnetic valve are arranged in the testing machine body, the standard pressure cavity and the testing cavity are connected with a pressure sensor respectively, the standard pressure cavity is connected with a second electromagnetic valve, the testing cavity is connected with a third electromagnetic valve, the vacuum pump is connected with a first electromagnetic valve which is communicated with the second electromagnetic valve and the third electromagnetic valve, and the control panel is connected with each component. Pressure of the testing cavity is adjusted to be identical to that of the standard pressure cavity, under the condition, a pressure simulation object bears water pressure in the water, a piece to be measured is measured and prevented from being directly placed in the water, and researching, developing and production costs can be reduced; and simultaneously, an actual pressure fragment in the piece to be measured is used for testing a result in the testing process, and the piece to be measured is not required to be detached to inspect an interior soaking test.
Description
technical field [0001] The invention relates to a testing device, in particular to a vacuum waterproof testing device. Background technique [0002] The internal parts of electronic products may be damaged due to water infiltration. Now that electronic products are becoming more and more sophisticated, the requirements for waterproofing are also gradually increasing. In order to meet the requirements of different waterproof levels for electronic products, the DUT can be kept waterproof at a depth of 1 meter for 30 minutes. Therefore, waterproof testing is required during product development or manufacturing. [0003] In the known waterproof test of electronic devices, after the device under test is directly placed in water, the device under test is disassembled to check whether there is water seepage inside. Therefore, when the DUT fails the waterproof test, moisture will penetrate into the DUT and cause damage. Moreover, this method is only applicable to a small amount o...
