-Safety Parameters-
Insulation resistance
Insulation resistance refers to the resistance value that occurs when a voltage is applied to the insulating part of the connector, so that leakage current occurs in or on the surface of the insulating part. It is mainly affected by factors such as insulation material, temperature, humidity, contamination and so on. The insulation resistance value provided on the connector sample is generally the index value under standard atmospheric conditions. Under some environmental conditions, the insulation resistance value will decrease to an unnecessary extent. In addition, pay attention to the test voltage value of the insulation resistance. According to the insulation resistance (MΩ) = applied to the insulator voltage (V) / leakage current (μA) to apply different voltages, there are different results. In the test of the connector, the applied voltage generally has three grades: 10V, 100V, and 500V.
Pressure resistance
The withstand voltage is the critical voltage that can withstand higher than the rated voltage within a specified period of time between the mutually insulating parts of the contact pair or between the insulating part and the ground without causing breakdown. It is mainly affected by contact pair spacing and creepage distance and geometry, insulator material as well as ambient temperature and humidity, atmospheric pressure.
flammability
Any connector is inseparable from the current when working, which has the risk of fire. Therefore, the connector is required not only to prevent ignition, but also to self-extinguish within a short period of time once ignition and fire occur. When selecting, pay attention to choosing electrical connectors with flame-retardant, self-extinguishing insulating materials.
