Title:
PIEZOELECTRIC RELAY
Document Type and Number:
Japanese Patent JPS63308835
Kind Code:
A
Abstract:

PURPOSE: To perform such contact operation that is high in reliability by supporting and fixing a conductive flexible plate directly to a support block plane in a way of sticking a specific rate of the outer diameter with a bonding agent, and installing a traveling contact, performing the contact operation, in a movable part of a piezoelectric unimorph.

CONSTITUTION: A conductive flexible plate of a piezoelectric unimorph similar to a disc of a round form made up of sticking a sheetlike piezoelectric element to the flexible plate 7 is supported and fixed directly to a support block plane in a way of sticking one-third or so of the outer diameter with a bonding agent, and a traveling contact, performing contact operation, is installed in a movable part of the unimorph. That is to say, when voltage is impressed on input wires 6a and 6b connected each to the flexible plate 7 and the piezoelectric element 8, the piezoelectric element is bent whereby the traveling contact 3 comes into contact with a fixed contact 5, and these wires are come into a state of being turned on, and when this voltage impression is released, the traveling contact 3 comes off the fixed contact 5 and they come off. Thus, the support block and the piezoelectric unimorph are fixed by bonding so that stable bending operation is maintainable.
