| Abstract: |
| The paper aims to research the corrosion problems of electrical connector in electronic equipment. Taking typical electrical connectors of military aircraft as the research object, the accelerated corrosion test was carried out under laboratory conditions to simulate the marine environment conditions of military aircraft in service. The macroscopical and microscopic corrosion morphology, the change laws of contact resistance and insulation resistance of electrical connectors were obtained, and the effects of loaded current and unloaded current on corrosion behavior of electric connectors were analyzed. In the first three cycles of the corrosion test, the insulation resistance varied drastically between 1500-0 MΩ and dropped to 0MΩ by the fourth cycle, completely lost the insulation properties. The results show that the load current significantly aggravates the corrosion of the electrical connector; leading rapid increase of the contact resistance. The corrosion remarkably deteriorates the electrical conductivity of the electrical connector. |
