Abstract
Abstract An electrical penetration assembly for installation in a containment wall formed of a nozzle extending through the wall and terminating in flanges at each end thereof. A canister assembly formed of a pipe member is positioned within the nozzle and extends through the containment wall. A glass-sealed hermetic header is positioned in the pipe member at the first end thereof and is secured to the pipe member at one end. A plurality of electrical conductors, terminating in electrical contacts, extend through the header and are sealed thereto, each of the conductors extending through the header to the other end of the pipe member. Means are provided for supporting the conductors in the pipe member. Electrical contact terminals terminate the electrical conductors at the other end of the header. In addition, means are provided for securing the electrical contact terminal means to the other end of the pipe member. The securing means at the other end of the pipe member may comprise a second glass-sealed hermetic header. Electrical connection to the electrical contact in the header is made by individual electrical contacts. The first end of the pipe member is positioned at the external side of the containment wall, and a flange member is secured to the pipe end and adapted to be fastened to one of the nozzle flanges. In addition, a channel is formed in the flange member, the channel providing means for pressurizing the interior of the pipe member. Means are provided for determining leakage in the assembly. A terminal housing is secured to the flange member, the terminal housing providing environmental and mechanical protection for the terminal area.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
250 words
An electrical penetration assembly for installation in a containment wall having a nozzle extending therethrough and terminating in flanges at each end thereof comprising: a canister assembly formed of a pipe member adapted to be positioned within said nozzle; a metal header secured to said pipe member at a first end thereof; a plurality of electrical conductors extending from said header to the other end of said pipe member; said header having a plurality of openings therethrough aligned with said electrical conductors; a conductive element in each of said openings extending beyond the opposite sides of said header to provide free ends, glass filling each said opening to provide a glass-to-metal seal between said element and said header; an electrical contact engaged with the free end of each said element on one side of said header facing said other end of said pipe member, said electrical conductors being connected to said contacts; an insulator secured to the other side of said header, said insulator having passages therethrough in alignment with said elements, an electrical contact in each passage engaged with the free end of said element on said other side of said header, a conductor extending through each said passage and connected to said contact, and a grommet in each said passage sealing said contact to said insulator; electrical contact terminal means terminating said electricaL conductors at the other end of said pipe member; and means securing said electrical contact terminal means to the other end of said pipe member.
