Electronic products: mobile phones, computers, telephones, watches, air conditioners, electric lights, etc. can be seen everywhere in our lives, and all of these products do not require high and low temperature reliability tests. Therefore, the programmable high and low temperature humidity and heat test box is indispensable. For example, a mobile phone needs to be tested whether it can be turned on and called normally under high temperature, low temperature or humidity. For such products that require live testing, please explain to the manufacturer in advance that you can open a test lead hole on the side of the machine for power-on testing. The test lead hole is treated with a special structure, which will not have much impact on the sealing and heat preservation of the box. Test lead holes generally have diameters of 25mm, 50mm, 80mm and 100mm. A user asked, during the high-low-temperature damp-heat test, how is the test wire placed in the equipment? Analyze the positive answer: Generally, the test lead holes are opened on the left side of the machine, and the conventional diameter is 50mm. In this case, as long as the product to be tested is placed neatly, the terminals are unified, and then externally connected through the test lead hole That is, if the cable is to be connected, it is generally necessary for the customer to prepare a flange to fix it. If it is lighter, you can handle it yourself. If it is heavier, let the manufacturer assist in processing, because the constant temperature and humidity box The inner wall is 1mm sus304 stainless steel, which cannot bear too much weight. Some need to have through holes on both sides of the box, and put a motor shaft in the middle, so that the equipment is tested under temperature and humidity. At this time, the aperture and some non-standard requirements need to be carefully confirmed with drawings. At this time, the test hole is not just for energization. Therefore, the placement method cannot be unified, but the premise is that safety is the first and the operation is careful.
