| Abstract: |
| This study aims to simulate and analyze the change rules of the plug and pull characteristics and contact resistance of the electrical coupler. By taking the typical electrical connector of a navy aircraft as the research object, the plug and pull characteristics of the electrical coupler connector were analyzed by ANSYS Workbench statics module, and the contact resistance was simulated by COMSOL. At the middle stage between the initial contact and the circular chamfer of the pin completely entering the chamfer at the end of the spring, the insertion force reaches the peak; the circular chamfer of the pin is completely inserted into the chamfer of the spring, and the spring deformation reaches the maximum. The maximum stress is located at the groove on the inside of the root section of the spring; the contact resistance decreases with the increase of the contact pressure, increases with the increase of the surface roughness height, and decreases with the increase of the rough slope. The change rules of insertion force, contact pressure and deformation during the plug and pull process is determined by the material and structure of the connector. The change of contact pressure and surface roughness has a significant regular effect on the contact resistance. |
