Abstract
PURPOSE: To enhance productivity by the procedure in which a high mold separability of a spacer is built into between an outer case into which a transformer body containing iron core and coil is housed and iron core by closing the outer case fitting hole and then a resin is injected into it and after the resin has cured it is taken out.
CONSTITUTION: The spacer 19 of silicone rubber, etc., having good mold separability, which is connected with the connecting bar 18, is built into the four corners of the outer case 13, the lower end of the spacer 19 is inserted into between the outer case 13 and the iron core of the transformer body 17, and the spacer is fixed by positioning the transformer 17 and also by closing the fitting hole 14 for the outer case 13. Then, the casting resin 20 is injected into between them in such a way that the coil 16 of the transformer body 17 is covered and after the resin has cured the spacer 19 is taken out, whereby the cavity 21 is formed at the four corners of the outer case 13. Thus, a visual check on the position of the iron core 15 as well as the direct incorporation of it in a set in use by utilizing the fitting hole 14 and the fitting of the bottom plate 23 become possible, enhancing its productivity.
