Document Type and Number:
Japanese Patent JP6744299
Kind Code:
B2
Abstract:
The present invention is a structure of an electrical connection portion formed by thermal bonding of a terminal 53 of a current-carrying component 50 of a motor and a winding wire 30. The terminal 53 includes a lock portion 53a positioned on a base end side and a fusion portion 53b positioned on a distal end side. The winding wire 30 includes a binding portion 31 wound around the lock portion 53a and has a one end portion 36 coupled to a molten ball 55 generated at the fusion portion 53b; and a coupling wire portion 33 tightly stretched from a main winding wire portion 34 of the motor disposed in a wound state and continuous to the other end portion of the binding portion 31. The one end portion 36 of the binding portion 31 is in a state where tension pulling the coupling wire portion 33 to the main winding wire portion 34 side does not act.
