Title:
PIEZO RELAY
Document Type and Number:
Japanese Patent JPH0426030
Kind Code:
A
Abstract:

PURPOSE: To facilitate fixation of a driving part and construct piezo relay in a small size by furnishing a card interlocking with the motion of an actuator, a movable spring which moves interlocked with the card, and a stationary spring having a contact mating with the contact of the movable spring.

CONSTITUTION: Within a base 1 are flatly arranged an actuator 3, a card 7 interlocking with its motion, an actuator accommodation part 2 having a stopper 8 which stops the motion of the actuator 3, a movable spring 9 interlocking with the motion of the card 7, and stationary springs 10A, 10B mating with this movable spring 9. When high frequency continuous pulses are impressed on a drawout lead terminal 13, a U-form foot 5 makes stamping motions and moves as creeping on the surface of the R part 15 of the actuator accommodation part 2, and interlocked therewith the card 7 moves in the direction of arrow, and the stopper 8 works so as to give the desired contact pressure to a stationary contact 12A. Thereby fixation of the driving part is facilitated, and piezo relay as the object of invention can be accomplished in a small size.
