Abstract
Abstract An interconnector for installation in an opening in a wall to provide at least one electrical connection through said wall, and a method for making same. The interconnector comprises a one piece tubular metal shell, at least one conductor within said shell, and two spaced apart glass sealing members supporting said conductors within said shell. The shell includes at least one port allowing access to the space interior of said shell and between said sealing members. The method for making the interconnector includes the steps of supporting one of the sealing members with a layer of inert flowable material, and subsequently removing the material through the port.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
An interconnector for installation in an opening in a wall to provide at least one electrical connection through said wall, said interconnector comprising: a one-piece undivided tubular metal shell; at least one conductor within said shell and extending parallel to the longitudinal axis of said shell; and two glass sealing members spaced apart along said axis and pre-sealed against the inner surface of said shell and around said at least one conductor, the entire space enclosed by said two glass sealing members and the inner surface of said shell consisting of an empty pressure chamber through which only said at least one conductor passes, said glass sealing members supporting said conductor.
Claim 2
Dependent Claim
111 words
An interconnector for installation in an opening in a wall to provide at least one electrical connection through said wall, said interconnector comprising: a one-piece undivided tubular metal shell; at least one conductor within said shell and extending parallel to the longitudinal axis of said shell; and two glass sealing members spaced apart along said axis and pre-sealed against the inner surface of said shell and around said at least one conductor, the entire space enclosed by said two glass sealing members and the inner surface of said shell consisting of an empty pressure chamber through which only said at least one conductor passes, said glass sealing members supporting said conductor.
Claim 3
Dependent Claim
30 words
The inerconnector as claimed in claim 1, wherein said shell includes at least one port extending through the wall of said shell to provide access to said empty pressure chamber.
Claim 4
Dependent Claim
26 words
The interconnector as claimed in claim 1, wherein said glass sealing members are sealed to the inner surface of said shell by fusing said sealing members.
Claim 5
Dependent Claim
21 words
The interconnector as claimed in claim 1, further comprising means to detachably connect mating connectors to both ends of said interconnector.
Claim 6
Dependent Claim
33 words
The interconnector as claimed in claim 1, further comprising means to mount said interconnector in an opening in a wall, such that a double seal is provided between either side of said wall.
Claim 7
Dependent Claim
47 words
The interconnector as claimed in claim 5, wherein said means to mount includes two spaced-apart annular channels in the outer surface of said shell, and an `0`-ring disposed in each of said channels such that said `0`-rings establish said double seal between said shell and said wall.
Claim 8
Dependent Claim
20 words
The interconnector as claimed in claim 5, wherein said double seal is formed by means recessed into said metal shell.
