| 目的 针对湿热海洋环境下接插件带电腐蚀行为进行研究，为接插件材料的选材设计、维护和更换等提供科学依据。方法 采用温湿度记录仪以及无氧铜测试片等对三亚自然环境试验站的腐蚀环境进行监测，分析环境条件的变化规律，同时通过湿热海洋自然环境暴露试验对电路板贴片式和插针式接插件的带电和不带电的腐蚀行为进行研究，分析接插件在两种工况下的腐蚀行为规律及差异。结果 三亚湿热海洋大气环境1—3月份呈干湿交替循环，每天至少发生1次循环，每天平均潮湿时间分别为6.0，7.4，11.6 h。1—3月份的环境腐蚀性均为GX级，其中 3月份腐蚀环境较1月2月更加严酷。贴片式数据通信接插件在带电和不带电工况下湿热海洋环境自然暴露3个月后，腐蚀行为基本相似，无明显差异，接触电阻没有发生变化，绝缘电阻均降为107 Ω，金属元器件均未发生明显腐蚀。插针式接线端子在带电和不带电工况下湿热海洋环境自然暴露3个月后，接触电阻未发生变化，但腐蚀行为存在明显差异，在不通电流工况下，螺钉发生严重腐蚀，绝缘电阻下降为106 Ω，而在3 A电流通电工况下，螺钉未发生腐蚀，绝缘电阻均大于109 Ω。结论 湿热海洋环境下电流对不同接插件腐蚀行为影响存在差异，对贴片式数据通信接插件腐蚀行为基本不影响，对插针式接线端子腐蚀行为存在一定的保护作用。 |

| Objective To research corrosion behavior of charged connectors in wet and heat marine environment to provide scientific evidence for the material selection, maintenance and replacement of connectors. Methods Temperature and humidity recorder and anaerobic copper test films were applied to monitor the corrosion environment of Sanya natural environment test station to analyze the law of change of environmental conditions. At the same time, the corrosion behaviors of the electrically charged and uncharged PCB patch and pin connector were researched by exposing test in wet and hot Marine natural environment. The corrosion behavior rule and the difference of connectors between the two working conditions were analyzed. Results From January to march, the humid and hot ocean atmosphere in Sanya was alternately wet and dry. The cycle was at least one cycle per day. The average humidity time each day was 6.0 h, 7.4 h and 11.6 h respectively. From January to march, the environmental causticity was GX level. In March, the corrosive environment was more severe than January and February. After three months of natural exposure in wet and heat marine environment, the corrosion behavior of the electrically charged and uncharged patch type data communication connector on the was basically similar, there is no obvious difference. The contact resistance did not change. The Insulation resistance was reduced to 107 Ω. There was no obvious corrosion occurred in metal components. After three months of natural exposure in wet and heat marine environment, the contact resistance of insert pin type terminal did not change. However, there were obvious differences in corrosion behavior. Under the uncharged conditions, the screws of insert pin type terminal were severely corroded. The insulation resistance of insert pin type terminal was reduced to 106 Ω orders of magnitude. However, there was no corrosion of screws under the charged working condition. The insulation resistance was maintained in 109 Ω orders of magnitude. Conclusion In the wet and hot ocean environment, there were differences in the effect of current on corrosion behavior of different connectors. For patch type data communication connectors, the corrosion behavior is almost not affected. However, it protects corrosion behavior of pin terminal to a certain extent. |
