The technical parameters of circular connector
< / p > < p > rated voltage < / p > < p > it determine the maximum voltage in the process of standard operation. The circular connector performance is associated with rated voltage. Insulation resistance of < / p > < p > < / p > < p > insulating ability of a material is defined as between adjacent contact or contact with the ground to form the ability of high impedance as much as possible. Mechanical life cycle < / p > < p > < / p > < p > define plug ( The process of mechanical connection and disconnection of circular connector) , during which the contact surface will not wear, avoid contact resistance increases. < / p > < p > insulated compatibility ( Air clearance and creepage distance) < / p > < p > it defines the minimum air gap ( The minimum distance between the live parts) in the air And the minimum creepage distance ( The minimum distance between the insulation on the electric parts) To avoid electrical flashover. Minimum creepage distance value depends on the insulation materials and pollution levels. Pollution extent < / p > < p > < / p > < p > pollution ( 1 - 4) Defines the dielectric strength and/or surface resistance reduced pollutants ( Solid, liquid or gaseous impurities) The amount of. For industrial applications, the pollution degree is usually 3: electrical conductivity, or dry of non-conductive pollution. The latter will pass the expected melt and become conductive. < / p > < p > current load < / p > < p > circular connector of the current load - defines the environment temperature Permanent under 40 ℃ and at the same time through all the contacts of the maximum allowable current. Current spontaneous total calories and related environmental temperature cannot exceed circular connector materials thermal properties determine the temperature of the upper limit. Describe the derating curve circular connector the relationship between the current load and environmental temperature. In practice, allowing a high current appears on the contact, because not all contact with maximum rate in permanent electricity. Through the test to determine the precise value at a time. < / p >
