Abstract
In the case where a power supply circuit assembly having a small transformer and various electronic components mounted on a mounting substrate is housed in an insulating case, and the case is filled with a resin, the occurrence of cracks at soldering parts situated around the roots of pin terminals projecting from a lower surface of the mounting substrate is avoided. In a circuit block configured in such a manner that an assembly (,) comprising a mounting substrate (,) constituting the power supply circuit is housed in a case (,), and the case (,) is filled with a resin (,), primary-side pin terminals (,) and secondary-side pin terminals (,) are formed to have an L-shape, and their linear portions pass through a coil bobbin (,). It is also configured in such a manner that the mounting part of the coil bobbin (,) makes contact with the upper surface of the mounting substrate (,) and is mounted on the mounting substrate (,), and an opening (,) is provided at roughly the center of the mounting substrate (,).
