Abstract

PURPOSE:To easily remove a part inside a leg of a terminal block which is shaved on the occasion of fitting, by a method wherein a stepped part intruding into a slit when the leg is inserted completely is provided inside the leg. CONSTITUTION:An inside leg 8 of a terminal block 11 fitted to a stator core 6 comes into contact with a coil 5, on the outside, and with the stator core 6, on the inside, and a stepped part 13 is provided on the inside. When the terminal block 11 is fitted to the stator core 6, in this case, the inside of the inside leg 8 is shaved by an edge part 14 of the stator core 6. A part 15 thus shaved continues to the stepped part 13, and when the stepped part 13 intrudes into a slot 4 as the inside leg 8 is inserted completely, as shown in the figure, it is cut off from the inside of the inside leg 8. Since the shaved part 15 is removed and disposed of in this way, it is prevented that the shaved part comes into contact with a rotor 7 rotating inside the stator core 6 and thus the occurrence of an abnormal sound and a faulty operation of a motor are avoided.

め上述のようには削られない。One inner leg 8 of the terminal block 11 has an outer surface in contact with the coil 5, an inner surface in contact with the stealth coil 5, and a stepped portion 13 on the inner surface. In this case, when attaching the terminal block 11 to the stator core 6, the inner surface of one of the inner legs 8 slides against the stator core 6 in a state in which it contacts the stator core 6, and at this time, as shown in FIG. The inner surface of the leg 8 is scraped by the edge portion 14 of the stator core 6 as shown in FIG. This cut portion 15 is the L arrangement portion 1
When the inner leg 8 is completely inserted as shown in FIG. 3 and the stepped portion 13 enters the slot 4, it is separated from the inner surface of the inner leg. Therefore, the shaved portion 15 can be easily removed and disposed of.
Moreover, the shaved portion 15 does not come into contact with the rotor 7 rotating inside the stator core 6, and no abnormal noise is generated or the motor malfunctions. The outer surface of the one inner leg 8 is not shaved as described above because the coil 5 contacts it.

はコイル５が接触するため削られない。The outer leg 10 has an outer surface in contact with the data core 6 and an inner surface in contact with the bipedal coil 5. In this case, 1. In mounting the stator core 6, the outer surface of the outer leg 10 is shaved off by the edge portion 17 of the stator core 6, as shown in FIG. 4a. This shaved portion 18 does not have a stepped portion 13 mentioned above that enters into the slot 4 on the outer surface, so it is not separated from the outer surface even when the outer leg 10 is completely inserted, and is not separated from the outer surface as shown in FIG. 4. It will remain attached. However, this shaved portion 18 is as far away from the rotor 7 as it is, and even if left as it is, it will not come into contact with the rotor 7 and will not cause the W tooth noise 11 or malfunction of the motor. The inner surface of the 1° outer leg 10 is not scraped because the coil 5 contacts it.
