Safety Parameters For Electrical Connector
Dec 20, 2018

Insulation resistance is the resistance value presented by applying a voltage to the insulating part of the connector, thus causing a leakage current inside or on the surface of the insulating part. It is mainly affected by insulating materials, temperature, humidity, fouling and other factors. The insulation resistance values provided on the connector sample are generally the indicator values under standard atmospheric conditions, and under certain environmental conditions, the insulation resistance value will be reduced to a lesser extent. Also pay attention to the test voltage value of the insulation resistance. According to the insulation resistance (MΩ) = the voltage (V)/leakage current (ΜA) added to the insulator to apply different voltages, there is no result.

In the connector test, the applied voltage is generally 10V, 100v,500v three gears.

Rated voltage Pressure resistance is the critical voltage between the mutual insulating part of the contact pair or between the insulating part and the grounding, which can withstand a higher than the rated voltage over a specified period of time without producing a breakdown phenomenon. It is mainly affected by exposure to spacing and crawl distances and geometries, insulator materials as well as ambient temperature and humidity, and atmospheric pressure.
