Abstract

PURPOSE: To improve assembling work efficiency, by assembling an iron core inside a cover set by an assembling jig while the positioning is being done by a jig, fixing the iron core simultaneously with the assembling, and omitting a clamper.
CONSTITUTION: Lower cover 1 is fitted to stopper 71 of jig 7 by fitting the stopper into cut hole 132. No.1 side leg 2 is placed there with E-chaped leg directd upward, on the top of which is mounted center leg 3, which is fitted with primary and secondary coils 41 and 42. Further, No.2 side leg 5 is placed on this with E-shaped leg directed downward, and thus the iron core is piled vertically. After the iron core was mounted on lower cover 1, upper cover 6 is mounted, and fixing claws 113 and 123 of lower cover 1 are bent along raised piece 61 of upper cover 6 and caulked. By this, even there is no clamper, the positioning of the iron core is done by the stopper and it is caulked between upper and lower covers, and thereby assembling work is greatly simplified.
