Method for producing centralized distribution unit of thin brushless motor for vehicle

摘要

In a method of producing a centralized distribution unit of a thin brushless motor for a vehicle having superior waterproof-ness and airtight-ness functions, and high dielectric strength, an insulating holder is provided with bearing recesses. Bus bars are bent from a substantially linear shape into a substantially annular shape, and inserted into holding grooves formed in the insulating holder. The insulating holder and bus bars are disposed in a molding cavity, and distal ends of holder supports that project from an inner wall of the molding cavity are engaged with the bearing recesses of the insulating holder. Resin is supplied into the molding cavity to form an insulation layer that covers the bus bars and an entire periphery of the insulating holder.
