Polymer Vehicle Electrical Modules With Integrated EMC Shielding

The patent applies composite materials by combining polymer-based substrate with conductive elements (metallic foils, fillers, or coatings) to create a housing that maintains the lightweight advantage of polymers while achieving the electromagnetic compatibility of conductive materials. The composite structure integrates the non-conductive polymer matrix with conductive additives to provide both mechanical properties and electromagnetic shielding capabilities.

The patent applies local quality by incorporating conductive elements only in specific locations and configurations where electromagnetic compatibility is needed, rather than using entirely metallic housing. The conductive foils, fillers, or coatings are strategically placed within the polymer housing to create localized conductive paths for electromagnetic radiation diversion, reducing overall weight while maintaining necessary EMC performance.

The patent merges the manufacturing processes by integrating the conductive elements directly into the polymer housing during molding or assembly, rather than requiring separate manufacturing steps for metallic housing fabrication. The polymer housing with embedded conductive foils, fillers, or coatings can be manufactured as a single integrated component, simplifying production while achieving the electromagnetic shielding效果 of traditional metallic housings.
