Abstract
Abstract An electrical feedthrough assembly for a containment structure having a specially controlled environment. The feedthrough assembly is designed to provide desired electrical performance while maintaining the integrity of the controlled environment of the containment structure under both normal and emergency conditions. The feedthrough assembly includes one or more header plates having removably mounted and redundantly sealed feedthrough modules provided therein with provision being made for internal manifolding so as to permit continuous pressure testing of the integrity of the module seals. Each feedthrough module has a construction which provides substantially rigid electrical and mechanical coupling between input and output conductors so as to eliminate the need for insulated wires within the assembly.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
163 words
An electrical feedthrough assembly for a containment structure having a controlled environment comprising: header means cooperatively mountable to said containment structure for feeding electrical connections to the interior thereof, said header means including at least one feedthrough module, conductor-receiving terminations at opposite ends of said module for respectively receiving conductors from inside and outside of said containment structure, each conductor-receiving termination including an insulative member supporting at least one hermetically sealed electrical terminal therein, said feedthrough module having interfacial means comprising an insulating member supporting at least one interfacial electrical contact for removable engagement with the terminals of said conductor-receiving terminations so as to provide substantially rigid electrical and mechanical coupling therebetween, means for removably mounting each conductor-receiving termination to said header means, and sealing means provided between said header means and said conductor receiving terminations at first and second spaced locations chosen so that removal of only oNe of said conductorreceiving terminations will not affect the sealing integrity of said containment structure.
Claim 2
Dependent Claim
163 words
An electrical feedthrough assembly for a containment structure having a controlled environment comprising: header means cooperatively mountable to said containment structure for feeding electrical connections to the interior thereof, said header means including at least one feedthrough module, conductor-receiving terminations at opposite ends of said module for respectively receiving conductors from inside and outside of said containment structure, each conductor-receiving termination including an insulative member supporting at least one hermetically sealed electrical terminal therein, said feedthrough module having interfacial means comprising an insulating member supporting at least one interfacial electrical contact for removable engagement with the terminals of said conductor-receiving terminations so as to provide substantially rigid electrical and mechanical coupling therebetween, means for removably mounting each conductor-receiving termination to said header means, and sealing means provided between said header means and said conductor receiving terminations at first and second spaced locations chosen so that removal of only oNe of said conductorreceiving terminations will not affect the sealing integrity of said containment structure.
Claim 3
Dependent Claim
24 words
The invention in accordance with claim 1, wherein said header means comprises a single plate having a module receiving opening for receiving said module.
Claim 4
Dependent Claim
57 words
The invention in accordance with claim 1, wherein said header means comprises first and second adjacent header plates having aligned module receiving openings for receiving said module wherein one of said conductor-receiving terminations is removably mounted to each header plate, and wherein each header plate contains one of said first and second locations of said sealing means.
Claim 5
Dependent Claim
27 words
The invention in accordance with claim 1, wherein said sealing means includes at least one self-energizing bi-metallic sealing member disposed between said header means and said module.
Claim 6
Dependent Claim
30 words
The invention in accordance with claim 4, wherein said sealing means provides for additional sealing by appropriately finishing predetermined abutting header and module seating surfaces spaced from bi-metallic sealing member.
Claim 7
Dependent Claim
40 words
The invention in accordance with claim 4, wherein said sealing means provides for additional sealing by the provision of at least one compressible gasket seal between said module and header means at a location spaced from said bi-metallic sealing member.
Claim 8
Dependent Claim
44 words
The invention in accordance with claim 1, wherein said header means and said module have a construction so as to provide an access opening to said module at a location between said first and second locations for monitoring the integrity of said sealing means.
Claim 9
Dependent Claim
59 words
The invention in accordance with claim 7, wherein at least one additional feedthrough module of like construction and arrangement is similarly mounted within said header means, and wherein said header means has a construction which provides common communication between the module access openings so as to thereby provide for simultaneous pressure testing of the sealing means of the modules.
Claim 10
Dependent Claim
41 words
The invention in accordance with claim 8, wherein said header means comprises a single header plate having module openings therein for respectively receiving a plurality of said modules, and wherein said common communication is provided by grooves interconnecting said module openings.
Claim 11
Dependent Claim
67 words
The invention in accordance with claim 8, wherein said header means comprises first and second adjacent header plates with said sealing means being located to provide a sealed interfacial opening therebetween, said header plates having a plurality of aligned module openings for receiving respective ones of said modules, said interfacial opening communicating with each module opening so as to permit simultaneous pressure testing of the module sealing.
