| 目的 分析得出电连接器失效的主要原因。方法 以海军某型飞机三个型号典型电连接器插孔端为主要研究对象，对电连接器宏观形貌进行目视检查分析，并采用扫描电子显微镜进行微观形貌观察，采用能谱分析仪进行微观成分分析，研究壳体表面和插孔接触面的化学成分组成。结果 腐蚀和磨损是外场电连接器失效的主要诱因，电连接器有一定程度的局部腐蚀，表面积聚的灰尘和海盐颗粒对腐蚀有较明显的促进作用。插拔不当造成的插针与插孔间同心度的偏差，与微动磨损共同作用加速了局部腐蚀。结论 插拔不当、微振磨损与局部腐蚀是导致电连接器性能下降乃至失效的三大主要因素。 |

| Objective To conclude the main reasons of connector failure. Methods Three types of typical electrical connectors for naval aircraft were studied by macro and micro morphology observation. SEM and EDS were used to analyze the microstructure, micro component and chemical composition of surfaces on shell and socket contact. Results Corrosion and wear were the main causes of connector failure in out-field. The electrical connectors had local corrosion to a certain extent. Obviously promotion to corrosion came from the dust and sea salt particles accumulated on the surfaces. The deviation of concentricity caused by incorrect insertion and extraction and fretting acted together, generating the local corrosion. Conclusion Incorrect insertion and extraction, fretting and local corrosion were the three main factors causing the performance of electrical connectors degrading to failure. |
