Abstract:
A fuse assembly including a fuse connected to two busbars, an injection molded base and an injection molded cover. The busbars are powder-coating with a powder-based adhesive or adhesion promoter, then cured in an oven. The busbars are then placed in the cavity image of an injection molding apparatus. Plastic is heated to a liquid form and injected into the cavity image. The resulting injection molded base is resistant to both dust and water, protecting the fuse inside.
