<p>PURPOSE:To sufficiently reinforce a printed substrate against a crack inexpensively and easily and to further effectively utilize the area of the substrate by providing a collar externally projecting and capable of mounting various types of electronic components on the lower end of an insulating case. CONSTITUTION:A collar 10 so formed as to externally project from the lower end of an insulating case 8 in which electronic components, such as a secondary coil and a rectifying diode are built in is reinforced by a triangular reinforcing rib substrate 11 in contact with a printed substrate 12. Electronic component mounts 13, 13' are provided on the collar 10, and since a resistor 14 and a transistor 15 can be, for example, mounted, the utility rate of the substrate 12 is not decreased even by a flyback transformer having a wide collar 10. The resistor 14, the transistor 15 and leads of the coil can be mounted by solder- connecting on the substrate 12.</p> |
