| 中文摘要: |
| 目的 研究电子设备中电连接器的腐蚀问题。方法 以军用飞机典型电连接器为研究对象，在实验室条件下模拟军用飞机服役的海洋环境条件，开展加速腐蚀试验。得到电连接器宏观、微观腐蚀形貌，接触电阻和绝缘电阻的变化规律，分析加载电流和未加载电流对电连接器腐蚀行为的影响规律。结果 在腐蚀试验的前3个周期，绝缘电阻值在1500~0 MΩ之间剧烈变化，到第4个周期降到0 MΩ，完全丧失绝缘性能。结论 加载电流明显加重了电连接器的腐蚀程度，导致接触电阻快速增大，腐蚀明显劣化了电连接器的导电性能。 |

| 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. |
