The insulation resistance value of the conductive part of the 5v relay between the non-conductive metal part (such as the iron core) and the shell, and between the conductive parts that are not electrically connected. When measured under standardized atmospheric conditions, the rated insulation voltage is equal to or If it is less than 60V, it should be no less than 400MΩ; if the rated insulation voltage is greater than 60V, it should be no less than 300MΩ. According to GB2423.4-81 "Electrical and Electronic Products Basic Environmental Test Regulations, Test Db; Alternating Damp Heat Test Method", after two cycles of damp heat test at a maximum temperature of 40℃, its insulation resistance value, rated insulation voltage If it is equal to or less than 60V, it should be no less than 5MΩ; if the rated insulation voltage is greater than 60V, it should be no less than 4MΩ.
After the 5v relay has been subjected to the damp and heat test, it needs to be able to accept 75% of the test value of the medium pressure test specified in paragraph 2.7.1 in the damp and heat box.
The conductive part of the 5v relay is between the non-conductive metal part (such as the iron core) and the shell, and between the conductive parts that are not electrically connected. If the dielectric withstand voltage test value is 2000V, it should be able to withstand the amplitude In the 5kV impulse voltage test, there was no insulation damage afterwards. During the experiment, a flashover that does not cause damage is allowed. After the experiment, the relay should meet the rules.
