What are the safety and electrical parameters of circular electrical connectors?

I. What are the safety and electrical parameters of circular electrical connectors? Electrical Parameters: 1. Rated Voltage: also called working voltage, which mainly depends on the insulating material used in the circular electrical connector and the distance between the contact pairs. When the voltage is lower than its rated voltage, some parts or devices cannot perform their functions.2. Rated current: also called working current. As with the rated voltage, circular electrical connectors can work properly when the current is lower than the rated current. In the design process of circular electrical connectors, the rated current requirement is met by the thermal design of the circular electrical connector, because when the current flows through the contact pair, the contact pair will generate heat due to the conductor resistance and contact resistance, and when the heat exceeds a certain limit, the insulation of the circular electrical connector will be destroyed, and the contact point will soften the surface coating, resulting in failure. Therefore, the rated current actually limits the temperature rise inside the circular electrical connector does not exceed the design value.3, contact resistance: contact resistance refers to the resistance generated by the two contacting conductors in the contact area, the contact resistance of the circular electrical connector refers to the contact pair resistance, including the contact resistance and the contact pair conductor resistance.4, shielding (Shieldability): in the modern electrical and electronic equipment, the The increasing density of components and their associated features impose strict limits on electromagnetic interference. Safety parameters: 1, insulation resistance: refers to the circular electrical connector insulation part of the voltage applied to the insulated part of the surface of the insulated part of the charged surface to cause leakage current and the resistance value presented. 2, withstand voltage: refers to the contact to each other between the insulated part or between the insulated part of the insulated part and the critical voltage between the ground, in the specified time to withstand higher than the rated voltage and not breakdown. It is mainly affected by the contact pair spacing and creepage distance geometry, insulator materials, ambient temperature and humidity, and atmospheric pressure.3, flammability: circular electrical connectors not only to prevent fire, once on fire but also in a short period of time self-extinguishing.
