Terminal for brushless motor and method for insert molding the same

摘要

A method for insert molding a terminal for a brushless motor and the terminal for a brushless motor formed by the insert molding method. The method includes: preparing multiple ring-shaped bus rings (11U, 11V, 11W and 11C) each having a predetermined number of positioning holes (15A, 15B and 15C) arranged in a circumferential direction; preparing multiple holding pins (21) each of which has positioning step portions (25A to 25C) having mutually different diameters and arranged at predetermined intervals in an axial direction so that the smaller diameters are positioned closer to a tip of the holding pin; stacking the multiple bus rings (11U, 11V, 11W and 11C) at predetermined intervals in the axial direction by inserting the holding pins (21) into the positioning holes (15A, 15B and 15C) in the bus rings (11U, 11V, 11W and 11C) ; and integrating the multiple bus rings (11U, 11V, 11W and 11C) with a mold resin in a state where the bus rings (11U, 11V, 11W and 11C) are held at the predetermined intervals in the axial direction by the tip and the positioning step portions (25A to 25C) of each of the holding pins (21).
