BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil element used for a flat motor and a jig for a coil winding device for a flat motor for forming the coil element.

[0002]

2. Description of the Related Art Conventionally, in order to form a coil element used in a flat motor, for example, Japanese Unexamined Patent Publication No.
A coil winding device for a flat motor as disclosed in Japanese Patent No. 159952 is used. FIG. 11 shows a coil element formed by the coil winding device for a flat motor disclosed in this publication. This coil element is formed by winding a coil wire e in a plurality of times on the same plane. It is formed in a flat shape.

FIGS. 12 and 13 show a coil winding device for a flat motor disclosed in this publication. The coil winding device for a flat motor draws out a coil wire e wound around a bobbin 18, and FIG. It repeats winding through the trumpet 19 and stacking in the same plane to form, for example, 25 coil elements E.

[0004] That is, this flat motor coil winding device includes a trumpet guide table 21 on a base 20,
And a coil holding guide table 22.
The trumpet 19 and the coil presser 24 slide along 2, but since both need to move in pairs, they are connected to each other by a link 25. A mold assembly 26 is rotatably supported by bearings 27 between the two guide tables 21 and 22.

This mold assembly 26 is formed by connecting 25 mold pieces 28 to each other and inserting a shaft 29 at the center.
A handle 30 is attached to one end of the shaft 29 for rotation. As shown in FIG. 14, each of the mold pieces 28 has a through hole 3 through which a shaft 29 is inserted in the center of a disc 31.
2 have been established.

The through hole 32 has a substantially trapezoidal shape as a whole in the same manner as the longitudinal section of the shaft 29, but has a projection 33 protruding from a peripheral wall thereof. The spacer 35 is fixed by screws. The spacer 35 is for forming a gap slightly larger than the diameter of the coil wire e between the mold pieces 28.

Therefore, the outer end face 3 of the spacer 35
5a serves to form a part of a trapezoid which is the shape of the coil element E together with the outer peripheral surface of the shaft 29 when the shaft 29 is inserted into the mold piece 28. In the coil winding device for a flat motor configured as described above, first, all 25 mold pieces 28 are inserted into the shaft 29 and fixed using an appropriate fastening tool.

Thereafter, when the winding around each mold piece 28 is completed, the mold assembly 26 is taken out together with the shaft 29 and heated. By this heating, the epoxy resin on the outer peripheral surface of the coil wire e is melted and, when it cools, the windings are temporarily bonded to each other. After this temporary bonding, the fastening tool is removed, the shaft 29 is pulled out, and the whole is shaken with the coil wires 13 at both ends.
Only the mold pieces 28 that have come into contact with 6 and the like fall, and as shown in FIG. 15, 25 coil elements E connected by connection lines e can be easily formed.

However, in such a conventional flat motor coil winding apparatus, when the coil wire e is moved from the mold piece 28 to the mold piece 28 to wind the coil wire e, as shown in FIG.
As shown in FIG. 1, it is very difficult to reliably position the coil wire e at the winding start point 37 and the winding end point 39, and at the winding start point 37 and the winding end point 39,
There was a problem that it was difficult to securely temporarily bond the coil wire e.

On the other hand, recently, as shown in FIG. 16, a loop R is formed to secure a length of a connection portion of a coil wire e connecting the coil elements E to each other. , Directly engaged with a projection formed on a commutator (not shown),
It is considered to connect. However, in the conventional coil winding device for a flat motor, in order to form such a loop R with a margin, it is necessary to increase the outer diameter of the jig. There was a problem that it became difficult.

[0011] In order to solve such a conventional problem, the present inventor has proposed that a flat coil element in which coil wires are wound plural times in a stack on the same plane by one coil wire. In a coil winding device for a flat motor for forming, a shaft is inserted through the center of a plurality of flat winding jigs arranged on the same axis to support these winding jigs, and Forming a protruding portion on one side of the tool for winding the coil wire a plurality of times in an inlaid state,
