Safety and electrical parameters of circular electrical connectors

Circular electrical connectors (aviation plugs) are low frequency electrical connectors. Nine shell numbers; 4 contact sizes; 30 hole positions. From hole 1 to hole 62. Adopt bayonet type quick connect system, easy to operate, reliable connection, vibration and shock resistant. Five-keyway positioning with blind insertion and anti-misinsertion function. Reliable hyperbolic wire reed holes make the connectors soft to insert and remove, with low contact resistance and reliable operation. There are five types of sockets. Conforming to military standard GJB2889, they are widely used in aerospace, aviation, navigation, railroad, field communication and various instruments. Electrical Parameters:1. Rated Voltage:Also known as the working voltage, it 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 components or devices cannot perform their functions.2. Rated current: also called working current. Circular electrical connectors, like the rated voltage, can work properly when the current is lower than the rated current. In the design process of circular electrical connector, circular electrical connector thermal design to meet the rated current requirements, because when the current flows through the contact pair, the contact pair will be due to conductor resistance and contact resistance and heat. When the heat exceeds the limit, it will destroy the insulation of the circular electrical connector, and the contact will soften the surface coating, leading to failure. Therefore, the rated current actually limits the internal temperature rise of the circular electrical connector from exceeding the design specified value.3. Contact resistance:Contact resistance refers to the resistance generated by the two contacting conductors at the contact position, 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:In the modern electrical and electronic equipment, the components and their associated functions of the density is increasingly high. Strict limits are imposed on electromagnetic interference. Safety parameters: 1. insulation resistance: refers to the circular electrical connector insulation part of the voltage applied, the insulation part of the leakage current caused by the charged surface resistance value. 2. withstand voltage: refers to the contact to each other between the insulated part or between the insulated part and the ground, in the specified time can withstand higher than the rated voltage without breakdown of the critical voltage. It is mainly affected by the contact distance and creepage distance geometry, insulator materials, ambient temperature and humidity, and atmospheric pressure.3. Flammability:Circular electrical connectors are not only for fire prevention, but also can be extinguished by themselves in a short period of time once on fire.
