Title:
A stator and an electric motor
Document Type and Number:
Japanese Patent JP6257791
Kind Code:
B2
Abstract:
This aluminum wire-copper wire connection method uses: a pressure contact terminal (1) having two conduction grooves (1a, 1b) provided to be parallel; and an insulation member (2) having a cavity (6, 7) capable of housing the pressure contact terminal (1) and having two anvils (9a, 9b) protruding inside the cavity (6, 7) and corresponding to the two conduction grooves (1a, 1b) of the pressure contact terminal (1). The method comprises placing an aluminum wire end (3, 4) on one of the anvils (9a) while placing a copper wire end (5) on the other anvil (9b), and inserting by pressing the aluminum wire end (3, 4) and the copper wire end (5) respectively into the two conduction grooves (1a, 1b) of the pressure contact terminal (1) housed inside the cavity (6, 7), thereby establishing a connection between the aluminum wire end (3, 4) and the copper wire end (5). In so doing, first the aluminum wire end (3, 4), and then the copper wire end (5), are inserted by being pressed into the two conduction grooves (1a, 1b) of the pressure contact terminal (1).
