Abstract:
A V1 semiconductor module has a coil terminal, which is directly connectable to a lead wire of a coil. As a result, the number of parts required to connect electronic parts is reduced. Further, since no printed circuit board is required, the coil terminal can be shaped in any size without being limited in correspondence to the thickness of a copper film of the substrate. The coil terminal and control terminals, which are connected to the printed circuit board having a control circuit for controlling current supply to the coil, are provided on different wall surfaces of a resin part. Thus, the coil and the printed circuit board can be readily connected to the coil terminal and the control terminals, respectively, resulting in simplification of the device.
Abstract:
A metal pattern for a high frequency signal is patterned on a flexile substrate, and the flexile substrate is bent in such a way as to form a substantially right angle at a spot corresponding to an end of the metal pattern for the signal. And an end of the metal pattern is fixedly attached to a lead pin for signaling, attached to a stem, for electrical continuity, so as to be in a posture horizontal with each other. Meanwhile, a part of the lead pins attached to the stem, being in such a state as penetrated through respective holes provided in the flexible substrate, is fixedly attached to a part of metal patterns provided on the flexible substrate so as to ensure electrical continuity therebetween.
