Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
100 words
A hybrid circuit package comprising: at least two hybrid circuits having several rigid leads; a printed circuit board secured substantially at right angles to the plane of each hybrid circuit for interconnecting said leads; a dismantleable framework for holding said at least two hybrid circuits and said printed circuit board, said dismantleable framework including first and second plastic molded parts having grooves therein for receiving and feeding said hybrid circuits; a hermetically sealed case for resiliently holding said dismantleable framework; and an electrical lead-out sealed in a wall of said case and coupled to said at least two hybrid circuits.
