Safety requirements for rectangular connectors
(1) Insulation resistance Insulation resistance refers to the resistance value presented by applying voltage to the insulation mark of the aviation plug so that leakage current occurs on the outside, inside or outside of the insulation mark.
Rectangular connectorWhat are the requirements for the safety of the product? The following rectangular connector manufacturers to give you a summary.
(1) Insulation resistance Insulation resistance refers to the resistance value presented by applying voltage to the insulation mark of the aviation plug so that leakage current occurs on the outside, inside or outside of the insulation mark. Mainly affected by insulation materials, temperature, humidity, fouling and other conditions. The insulation resistance value provided on the aviation plug sample is the index value under standard atmosphere. In some cases, the insulation resistance value decreases to some extent. Pay attention to the test voltage value of the insulation resistance. Standard insulation resistance (Mω) = voltage applied to the insulator (V)/leakage current (μA). If an inappropriate voltage is applied, it will produce inevitable results. In the test of aviation plug, the applied voltage is 10V, 100V and 500V.
(2) Withstand voltage Withstand voltage refers to the critical voltage at which the contact pair can withstand higher than the rated voltage without breakdown during the coincidence time between the mutual insulation mark or the insulation mark and the ground. It is mainly affected by contact distance, creepage distance, geometry, insulator material, temperature and humidity, and atmospheric pressure.
(3) Flammability Any aviation plug cannot work without current, so there is a danger of fire. Therefore, the aviation plug is required not only to prevent fire, but also to automatically extinguish in a short time once it is on fire. When selecting, pay attention to the electrical aviation plug of flame retardant self-extinguishing insulating material. Is the above rectangular connector manufacturers to introduce the rectangular connector safety summary.
