を遊嵌して隅取りコイルを電磁鉄心にろう付していた。[Detailed Description of the Invention] A conventional two corner corner coil device for an AC electromagnet such as an electromagnetic contactor press-fits both sides of a quadrilateral corner coil into a pair of grooves provided on the magnetic pole surface of an electromagnetic core. Alternatively, both sides of a quadrilateral cornered coil were loosely fitted into a pair of grooves provided on the magnetic pole surface of the electromagnetic core, and the cornered coil was brazed to the electromagnetic core.

の隅取りコイル３内に貫通するようになされる。However, when both sides of a four-sided three-sided corner coil are press-fitted and fixed into a pair of grooves on the magnetic pole surface of an electromagnetic core, when another core is attracted to the magnetic pole surface of the electromagnetic core, the impact force at that time is As a result, excessive stress is generated at both ends of both sides of the cornered coil, which has the disadvantage of causing both ends to break.Furthermore, when brazing the cornered coil to the electromagnetic core, the brazing process is troublesome and increases costs. There was a drawback. The present invention is intended to eliminate the above-mentioned drawbacks of the conventional art, and the embodiments of the present invention will be described below with reference to the drawings. 1 is an electromagnetic core made of laminated iron plates, and the magnetic pole face and the magnetic pole face or the magnetic pole face are By inserting both sides of the quadrilateral corner coil 3 into a pair of grooves 2 and Z formed in the vicinity, a portion of the magnetic pole face is made to penetrate into the quadrilateral corner coil 3.

しない効果がある。The base ends of each of the spring pieces 4 and 4 are fixed to both side surfaces of the electromagnetic core 1, and are connected to the fitting locking portions 5 and 5' of both end sides 3b and 3' of the quadrilateral cornered coil 3. b is fitted and locked. As described above, the present invention provides fitting locking portions 5 of each of the spring pieces 4, 4 that fix the base end to the electromagnetic core 1,
5', both end sides 3b and 3'b of the quadrilateral corner coil 3 are fitted and locked, so both end sides of the quadrilateral corner coil 3 are fitted into the fitting locking part of the free end of the spring piece. The corner cut coil can be installed by simply mating and locking it, making assembly extremely easy.Also, since both ends of the corner coil are locked to the fitting locking parts of the spring pieces, the magnetic pole of the electromagnetic core When another iron core is adsorbed onto the surface with an impact, the cornered coil moves somewhat toward the magnetic pole surface, so that excessive stress is not generated on the cornered coil, and the cornered coil is prevented from being damaged.
