PURPOSE:To provide an inexpensive device free from imperfect insulation, and improve the reliability, by forming a projection at an outer circumference of a side wall of a U-shaped portion of a bobbin, engaging the projection with an annular groove of a main yoke member, and fixing the assembly with a resin insulator. CONSTITUTION:An outer flange 10a of a main yoke member 10 formed of an electromagnetic sheet steel is formed at its inner peripheral portion with an annular groove 10d. A side wall 11a of a sectional U-shaped resin bobbin 11 is formed at its outer periphery with a projection 11d. An excitation coil 9 is wound around the bobbin 11 to form a coil assembly, and the projection 11d of the bobbin 11 is engaged with the annular groove 10d. Then, the coil assembly of the excitation coil 9 is fixed to the main yoke member 10, and a resin insulator 15 is filled and cured between the coil assembly and the main yoke member 10. Thus, the coil assembly of the excitation coil 9 is precisely fixed at a predetermined position of the main yoke member 10 to thereby eliminate imperfect insulation, protrusion of the excitation coil 9 from the main yoke member 10, leakage of the resin insulator or the like, and ensure the high reliability.

The excitation device for the conventional electromagnetic clutch was developed in 1986-395.
As described in No. 40, after winding an excitation coil around a bobbin made of resin and having an annular shape with a substantially U-shaped cross section and storing it in the yoke main member, the excitation coil and the yoke main member are assembled. During this process, a resin insulator was injected and hardened, and the excitation coil wound around the bobbin was insulated and fixed to the main yoke member. However, such conventional technology does not take into account positioning means in the axial and radial directions that can set the excitation coil at the optimal position within the main yoke member, and therefore, depending on work variations, etc. The excitation coil may be biased in the radial direction or lifted up in the axial direction within the main yoke member, and as a result, the outer peripheral surface of the excitation coil may come into contact with the outer flange of the main yoke member, causing insulation failure, or The coil may protrude from the opening end face of the main yoke member and come into contact with the input rotating body, or the thickness of the resin insulator may become uneven, causing cracks or damage to the lead wire extraction hole and grommet of the main yoke member. There is a potential for problems such as leakage of the resin insulator from the gaps between the parts, and sufficient consideration has not been given to these points.

In the above conventional technology, the excitation coil is inside the main yoke member,
Due to the lack of positioning in the axial and radial directions, due to variations in work, the excitation coil may be lifted up in the axial direction of the main yoke member or shifted in the radial direction. These unstable position settings of the excitation coils may result in poor insulation, excitation coils protruding from the open end of the yoke main member, and lead wire extraction holes provided in the yoke main member. There was a potential for problems such as leakage of resin insulators.

An object of the present invention is to provide a highly reliable excitation device for an electromagnetic clutch that is free from poor insulation, protrusion of the excitation coil from the main yoke member, and leakage of resin insulators.

The above purpose is to provide a plurality of protrusions radially and integrally on the outer circumference of the side wall of the bobbin, and to provide an annular groove in the main yoke member at a position facing the protrusions of the bobbin. This is achieved by fitting the protruding portion of the bobbin into the annular groove of the yoke member when the yoke is housed in the yoke main member.

The protruding part provided on the outer circumference of the bobbin is fitted into the annular groove provided in the main yoke member, so the fitted part prevents the bobbin around which the excitation coil is wound from floating toward the opening of the main yoke member. This prevents the excitation coil from being set in the main yoke member in an inclined state. That is, the excitation coil is set at an optimal predetermined position within the yoke main member. As a result, the adhesion between the grommet and the lead wire outlet hole of the main yoke member is improved, and the resin insulation does not leak.
The bobbin does not protrude from the opening end of the yoke main member, and the resin insulator is evenly filled into the gap between the yoke main member and the excitation coil, so there is no possibility of poor insulation.

The coil will no longer float up or be set in an inclined state within the yoke main member, and the sealing performance between the grommet and the lead wire outlet hole of the yoke main member will be improved. As a result, the excitation coil does not protrude from the opening end of the main yoke member, and the resin insulator filled in the gap between the excitation coil and the inner circumference of the outer flange of the main yoke member also has a uniform thickness. Since it is thicker, it is possible to eliminate cracks and insulation defects. Also, attach the grommet to the push part 11 of the bobbin.
Since it can be clamped between j, llk and the bottomed part 10c of the main yoke member, the sealing performance of the grommet is improved and the leakage of resin insulation from between the lead wire outlet hole and the grommet is also eliminated. .
