Abstract

Abstract A terminal device for a piezoelectric ceramic transformer of the plate-type consists of a rectangular ring made of rubber-elastic high-molecular material has two metallic members. The metallic members are mounted at opposite portions of the ring so as to contact respective input electrodes of the transformer when the terminal device is attached to the input section of the transformer. Input leads for the transformer will be connected to the respective metallic members serving as interconnection between the input electrodes and input leads. A terminal device for the output of the ceramic transformer is attached around the output section of the transformer so that the output can be taken out from any point of the output section.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 93 words
A terminal device for a piezoelectric ceramic transformer comprising a rectangular ring (10) made of rubber-elastic highmolecular material the inner peripheral dimension of which corresponds substantially to the outer peripheral dimension of the transformer, said ring having attached thereto at its opposite portions two rectangular cylinders (11, 11'') made of metal so that when said ring is mounted around an input section of the transformer said metal cylinders contact respective input electrodes of the transformer, wherein said ring urges said metal cylinders so as to make them intimately contact the respective input electrodes.
Claim 2
Dependent Claim 93 words
A terminal device for a piezoelectric ceramic transformer comprising a rectangular ring (10) made of rubber-elastic highmolecular material the inner peripheral dimension of which corresponds substantially to the outer peripheral dimension of the transformer, said ring having attached thereto at its opposite portions two rectangular cylinders (11, 11'') made of metal so that when said ring is mounted around an input section of the transformer said metal cylinders contact respective input electrodes of the transformer, wherein said ring urges said metal cylinders so as to make them intimately contact the respective input electrodes.
Claim 3
Dependent Claim 20 words
A terminal device for a piezoelectric ceramic transformer as specified in claim 1 wherein said ring is made of neoprene.
Claim 4
Dependent Claim 33 words
A terminal device for a piezoelectric ceramic transformer as specified in claim 1 wherein the inner peripheral dimension of said ring is made slightly smaller than the outer peripheral dimension of the transformer.
