Title:
PIEZOELECTRIC RELAY
Document Type and Number:
Japanese Patent JPS63308834
Kind Code:
A
Abstract:

PURPOSE: To fix a piezoelectric unimorph positively by joining a piezoelectric unit 1, similar to disc or a round form, to a case bottom surface in a way of sticking one third of the outer diameter or so with a bonding agent.

CONSTITUTION: When voltage is impressed on input wires 6a and 6b connected each to a flexible plate 2 and a piezoelectric element 1, a piezoelectric unimorph is bent, and a traveling contact 3 and a fixed contact 5 are made contact with each other, thus these wires come into a state of being turned on, and when this voltage impression is released, the traveling contact 3 comes off the fixed contact and thereby they come off. Thus, a piezoelectric unit similar to a disc or a round form is joined to a case bottom surface in a way of sticking one third or so of the outer diameter with a bonding agent whereby the case bottom surface doubles as a support part, and its structure is simplified, thus the piezoelectric unimorph can be easily and surely fixed with the bonding agent and, what is more, stable bending operation is maintainable as to piezoelectric relay contact operation.
