Abstract: An electronic component is mounted on one major surface of a dual side wiring substrate. A terminal is press-fitted into a mounting hole in the dual side wiring substrate from the one major surface side to be temporarily fixed in the substrate, and an electronic component is mounted on the other major surface of the dual side wiring substrate after soldering paste is applied. A frame having a plurality of bent pieces extending inwardly is mounted onto the dual face wiring substrate from a position above the substrate so that the bent pieces abut against the pattern of the dual side wiring substrate. The terminal press-fitted from the one major surface side, the electronic component mounted on the other major surface, and the frame are soldered simultaneously by a reflow method.

Abstract: An antenna device used for a UHF tuner or the like, which comprises a combination of an antenna coil formed of single-covered wire with an insulator covering the antenna coil. The insulator is dividedly molded into a coil containing member having an antenna coil containing recess and a terminal member having a pair of antenna terminals and a resistor containing recess, a fitting portion to be fitted between the coil containing member and the terminal member is provided, and at the terminal member a cover for closing an opening at the coil containing recess. The coil containing member containing the antenna coil in the coil containing recess and the terminal member containing a resistor in the resistor containing recess are integrally connected by press-fitting of the fitting portion and the antenna coil is housed in the insulator, thereby obtaining the insulating property equivalent to a double covered wire without deforming the the coil during or after the assembly of the antenna device.

Abstract: A construction for attaching terminals for a high frequency apparatus wherein a plurality of lead terminals are press-fitted in a terminal holder made of resin, and the terminal holder with the lead terminals inserted in apertures in a circuit board is clamped between the circuit board fixed to a chassis and a shield plate installed in the chassis.

Abstract: A high frequency apparatus such as an electronic television tuner comprises a main base plate having a circuit pattern and components disposed on it. A shield casing encloses and supports the main base plate by encompassing it at its peripheral edge. The shield casing is open at one side corresponding to one edge of the main base plate and is preferably also open at the upper and lower surfaces of the casing. The opened side of the shield casing is provided with an auxiliary base plate having a shield conductive film on its outer surface. The main base plate has a plurality of first apertures and the auxiliary base plate has corresponding pluralities of second and third apertures. Capacitor elements are inserted through at least some of the second apertures. The first apertures and apertures in the capacitor elements receive corresponding end portions of L shaped connection terminals.
