Title:
PIEZOELECTRIC RELAY
Document Type and Number:
Japanese Patent JPS63308837
Kind Code:
A
Abstract:

PURPOSE: To aim at improvement in performance for switching action, vibro- resistance, impact resistance, etc., by installing the fixed piece fixed to a support block plane with a screw at the specified rate of an outer diameter of a piezoelectric unimorph silimar to a disc or a round from, and installing a traveling contact in a movable part of the piezoelectric unimorph.

CONSTITUTION: In this relay, there is provided with a fixed piece 7 which is fixed to a support block plane with a screw as far as one-third or so of the outer diameter of a piezoelectric unimorph silimar to a disc or a round from made up of sticking a sheetlike piezoelectric element to a conductive flexible plate of metal or the like with a bonding agent. A traveling contact 3 is installed in a tip of this piezoelectric unimorph as corresponding to a fixed contact 5. This piezoelectric unimorph is fixed to a support block and it improves the extent of reliability in switching action or the like. In addition, in order to be directly fixed to a support block plane, its assembly is also easy and the support block is simplified as well. Thus, the support block and the piezoelectric unimorph both are maintained in a surely stable state, so that performance of a piezoelectric relay for swiching action, vibro-resistance, impact resistance, etc., is sharply improved.
