Abstract
Abstract A high voltage relay is provided in which the operating components of the relay are enclosed in a sealed envelope which may be evacuated. The relay to be described is a miniaturized high voltage relay capable, for example, of operating at voltages up to 5 kilo-volts, and in conjunction with relatively high frequencies. The envelope of the relay is composed of ceramic, and the relay is capable of efficient operation in wide extremes of ambient temperatures. The relay includes a linearly movable contact which makes connection with a fixed common electrical terminal through a resilient diaphragm which is constructed to permit free linear reciprocal movement of the movable contact and yet maintain a positive electric current to the common terminal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
A relay including: a housing; a plurality of annular contact members affixed to said housing at spaced positions therein; a movable element for the relay including an electrically conductive rod extending coaxially within said annular contact members; solenoid means attached to one end of said housing for selectively moving said rod in a rectilinear reciprocal manner between a first position and a second position with respect to said annular contacts; a resilient diaphragm composed of electrically conductive material attached to said rod and to one of said annular contacts and electrically connecting said rod to said one of said annular contacts, said diaphragm lying in a plane perpendicular to the axis of said rod; and at least one movable contact affixed to said rod for selective engagement with a further one of said annular contacts as said rod is moved between its first and second positions.
Claim 2
Dependent Claim
146 words
A relay including: a housing; a plurality of annular contact members affixed to said housing at spaced positions therein; a movable element for the relay including an electrically conductive rod extending coaxially within said annular contact members; solenoid means attached to one end of said housing for selectively moving said rod in a rectilinear reciprocal manner between a first position and a second position with respect to said annular contacts; a resilient diaphragm composed of electrically conductive material attached to said rod and to one of said annular contacts and electrically connecting said rod to said one of said annular contacts, said diaphragm lying in a plane perpendicular to the axis of said rod; and at least one movable contact affixed to said rod for selective engagement with a further one of said annular contacts as said rod is moved between its first and second positions.
Claim 3
Dependent Claim
17 words
The relay defined in claim 1, in which said resilient diaphragm has a photo-etched pattern extending therethrough.
Claim 4
Dependent Claim
29 words
