Title:
PIEZOELECTRIC RELAY
Document Type and Number:
Japanese Patent JPS63308836
Kind Code:
A
Abstract:

PURPOSE: To make a piezoelectric relay resistible to dust and humidity and easier for handling by setting the piezoelectric unimorph provided with a traveling contact from a flat opening in the casing thickness direction of a casing case, and installing another sealing cover in the flat opening of the casing case.

CONSTITUTION: A piezoelectric unimorph 5 is made up into a form similar to the disc or the round form that stuck a flexible plate consisting of a sheetlike piezoelectric element 6 and a conductive material of metal or the like. And, a traveling contact 8 is attached to a tip of the unimorph 5, while a casing case 9 cases the unimorph 5 and it is set in from flat opening in the casing thickness direction, fixing 1/3W1/5 or so of the outer diameter of the unimorph 5 to a support part 9a of the case 9. And, the flat opening of the case 9 is sealed with a sealing cover 11. When 1/3 or so of the outer diameter is supported and fixed like this, displacement and displacement load of the unimorph 5 can be efficiently taken out, thus such a piezoelectric relay that is resistible to dust and humidity owing to the sealing cover is produced.
