Before connecting, check DIN 41612 Connectors Factorythere is any excess, whether there is rusty outer casing, abnormal pinhole, inflexible locking mechanism, etc. Reliability analysis of aerospace electrical connectors The reliability of electrical connectors includes inherent reliability and reliability in use.

Therefore, it is particularly urgent to effectively carry out the reliability analysis of electrical connectors in the design work of aerospace products to improve the quality of aerospace products. ⑿ The appropriate quality level should be selected according to the role and position in the complete machine system. Carrying out the reliability analysis of aerospace electrical connectors plays a pivotal role in identifying and eliminating potential quality defects of aerospace products. 5.

When performing performance tests on electrical connectors, you should use qualified and new plugs (seats) or analog pins. ⑩The form of tail attachment. A failure of a contact will result in the failure of the entire weapon system. Prevent accidents such as false welding, false pressure, end connection falling off, fracture and pollution. λp=λb×πE×πP×N λcyc(3) where:

N—the number of working pins. 2. Measures to ensure the reliability of aerospace electrical connectors 1. λp=λb×πE×πQ×πP×πK×πC where: λp—working failure rate; λb—basic failure rate; πE—environmental coefficient; πQ—quality coefficient; πP—contact coefficient; πK—plugging coefficient; πC-jack structure coefficient. 4., are critical to the inherent reliability of the product important. between contacts and between contacts and shell. The overall electrical connector failure statistics account for a large proportion. Reasonably select the quality level. ⑾ Overall dimensions.
