摘要
Abstract
The sealing performance of connectors is the key performance indicator for evaluating their reliability.The sealing performance of most connectors is mainly achieved through the interference fit design of rubber parts.Based on the fluorosilicone rubber standard parts,a study on reliability prediction methods based on the physics of failure(PoF)and quality consistency is carried out.Firstly,the typical failure mechanisms of rubber parts in electrical connectors are studied,and a physics-of-failure model is established.Then,using standard parts,the mathematical relationships between material properties,structural parameters,process parameters,and the coefficients in the physics-of-failure model are studied to establish a transfer model.Finally,the accelerated degradation tests are conducted under the typical stress conditions to verify the effectiveness of the proposed method.The verification results show that the proposed model can accurately calculate the physics-of-failure models of rubber parts with different specifications,with an average accuracy of up to 90％.关键词
