Abstract: Based on requirements from the German Electrical and Electronic Manufacturers' Association regarding wiring, thermal conduction parameters, and other criteria for connectors in vehicle systems, this study shows the structural models, circuit models, and relevant thermal simulation parameters required for connector thermal analysis. This ensures accuracy in thermal simulation results across different clients and suppliers. The paper aims to implement parametric design for connector models, comparing 1D thermal simulation outcomes with 3D thermal simulation and experimental results to validate accuracy. Results demonstrate high consistency between1D thermal simulation and 3D thermal simulation and experimental validations, with the highest temperature observed at the terminal contact area. This confirms that parametrically designed parameters of 1D thermal simulation are suitable for transfer and joint simulation applications in supplier-client collaboration. The study provides an operational and verifiable engineering scheme for the industry.
