Terminal connector and terminal connection method

A terminal connection method which connects between each phase terminal of a motor-side terminal of a motor and each phase terminal of a unit-side terminal of a control unit of said motor, the motor having a shaft extending in a shaft direction, the method comprising steps of:

• abutting a portion of said each phase terminal of said motor-side terminal with a portion of said each phase terminal of said unit-side terminal to form abutting portions which extend to a radial direction of said motor, the abutting portions being arranged in a stair-like manner in the shaft direction so as to be at different heights;
• applying a plastic deformation to the abutting portions in a direction perpendicular to said radial direction of said motor with a machine work;
• forming junction sites between said motor-side terminal and said unit-side terminal;
• forming a retaining mechanism of said junction sites;
• and
• forming an electrical contact of said motor-side terminal and said unit-side terminal.

A terminal connection method which connects between each phase terminal of a motor-side terminal of a motor and each phase terminal of a unit-side terminal of a control unit of said motor, the motor having a shaft extending in a shaft direction, the method, comprising steps of:

• forming processing sites of a hole, or a recess machining, or a convex machining, or a bending, or a thinning on at least one of said motor-side terminal or said unit-side terminal in a shaft direction in a stair-like manner so as to be at different heights;
• abutting a portion of said each phase terminal of said motor-side terminal with a portion of said each phase terminal of said unit-side terminal to form abutting portions which extend in a radial direction of said motor and are positioned at said processing sites;
• applying a plastic deformation to abutting portions in a direction perpendicular to said radial direction of said motor with a machine work;
• forming junction sites between said motor-side terminal and said unit-side terminal;
• forming a retaining mechanism of said junction sites;
• and
• forming an electrical contact of said motor-side terminal and said unit-side terminal.
