Abstract
Abstract The main electrodes of a sealed semiconductor device are clamped between opposing metal members of a pressure assembly, and gaps between opposite ends of the insulating sidewall of the device and the respectively adjacent metal members are closed by resilient O-rings disposed in compression in the gaps and respectively circumscribed by rigid retaining rings.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
24 words
The assembly of claim 1 in which said relatively rigid means for impeding blowout of said ring is a flange of said one member.
Claim 2
Dependent Claim
23 words
The assembly of claim 1 in which said relatively rigid means for impeding blowout of said ring is a flange of said diaphragm.
Claim 3
Dependent Claim
23 words
The assembly of claim 1 in which said relatively rigid means for impeding blowout of said one ring is a separate metal ring.
Claim 4
Dependent Claim
55 words
The assembly of claim 1 in which said hollow insulator is in the form of a sleeve, part of said metal member overlies one end of said sleeve, and said one ring is disposed in a gap between said part and said one end of said sleeve, whereby said gap is sealed by said ring.
Claim 5
Dependent Claim
52 words
The assembly of claim 5 in which said ring is an O-ring and has a diameter approximately the same as that of said one end of said sleeve, and in which said relatively rigid means is a separate metal ring having an inside diameter larger than the outside diameter of said O-ring.
Claim 6
Dependent Claim
28 words
The assembly of claim 6 in which said metal ring includes a skirt overlapping said one end of said sleeve to limit displacement thereof in a radial direction.
Claim 7
Dependent Claim
28 words
The assembly of claim 6 in which said metal ring includes a skirt overlapping said part of said metal member to limit displacement thereof in a radial direction.
Claim 8
Dependent Claim
132 words
In a semiconductor rectifier assembly: a. a semiconductor device comprising a pair of main electrodes, a semiconductor body disposed mechanically between and electrically in series with said electrodes, an insulating sleeve, and annular metal diaphrams for joining said electrodes to opposite ends of said sleeve to form a sealed housing for said body; b. means outside said housing for connecting said device to an external electric circuit comprising a pair of metal members having facing contact surfaces, said device being disposed with its main electrodes between the facing contact surfaces of said members but with its insulating sleeve spaced therefrom; c. a pair of O-rings disposed between said sleeve and the respective metal members for sealing the gaps therebetween; and d. relatively rigid means circumscribing the respective O-rings for impeding blowout thereof.
Claim 9
Dependent Claim
26 words
The assembly of claim 9 including pressure-applying means connected to said metal members for compressing said O-rings and for pressing said main electrodes toward one another.
