High frequency relay and television tuner using it

摘要

PROBLEM TO BE SOLVED: To provide a high frequency relay for switching a high frequency signal by displacing and driving a movable contact of a contact mechanism by making either of a pair of armatures extending from both poles of a magnet mounted on a card contact with a core of an electromagnet, wherein a drive mechanism for driving the contact mechanism is arranged in parallel with the contact mechanism, and the card is supported by a pair of balancing springs extending from a base, capable of adjusting resilience easily with high precision in providing a cushioning spring for suppressing the generation of an impact sound and the wear of the armatures caused by a collision to the cores of the armatures.;SOLUTION: The cushioning springs 51, 52 formed of support parts 51a, 52a of which base end sides are engaged in holes 53, 54 pierced in a base 20, and plate spring parts 51b, 52b extending from free end sides of the support parts 51a, 52a are inserted in the base 20, and the card 31 is resiliently energized from outward by the plate spring parts 51b, 52b.;COPYRIGHT: (C)2007,JPO&INPIT
