In the stator 4, the coil 2 is wound around the slot of the core 3, and the terminal is connected to the substrate 1 in the vicinity of the coil end 4 a. The insulating paper 6a provides insulation between the coil 2 and the core 3, the insulating paper 6b provides insulation between the coil 2 and the frame 5, and the insulating paper 6c provides insulation between the coil 2 and the substrate 1.
The connection process of the coil end 10 is performed as follows.
Details of the coil terminal processing are shown in FIG. FIG. 6A shows a state before the substrate is attached, and FIG. 6B shows a state after the substrate is attached. In the state of FIG. 6A, the coil end 10 is not yet fixed. The coil end 10 is positioned by a jig or the like, and then connected to the board land 8 by soldering.
Thus, the conventional coil terminal processing apparatus performs accurate positioning of the coil end 10 with a jig or the like.
In addition, as a treatment of the coil terminal, a structure in which a coil cover having an internal cross section formed in the shape of a coil end is attached to the coil end and a lead wire is connected to a terminal provided in the coil cover has been proposed (for example, Patent Document 1).
