Abstract A conductor having a plurality of continuous peripheral recesses is received within a tubular member, the internal surface of which member is also provided with a number of recesses. Resilient seals are located in certain, but not all, of the recesses. These seals are of such dimensions as to extend above the surface or outwardly of their associated recesses, as the case may be. An encapsulant or molding material is provided, filling the space between the conductor and the tubular member. The set-up material compresses the resilient seals to form in the area of the seals a firm fluid-tight seal. Also, the material anchors itself to the conductors via the seal-free recesses. In the event that separation of the material from the conductor or tubular member occurs during use, the compressed resilient seals still maintain a hermetic condition.
A sealed insulated electrical connector emplanted within a wall separating fluids of considerably different pressures to provide through-wall connection, comprising: a hollow metal tube, the inner wall surface of which is formed into a plurality of continuous longitudinally spaced, circumferential grooves; at least one metallic rod extending along the tube bore, said rod including a plurality of spaced, circumferential grooves; first resilient annular members received within certain grooves of said metal tube leaving certain other of said grooves free; second resilient annular members received within certain of said metallic rod grooves leaving certain other of said grooves free; and a quantity of a rigid, adhesive, insulative material received within said metal tube filling the space between said inner tube wall surfaces and said rod and in continuous adhering contact therewith; said metal tube with metallic rod and insulative material being secured within a wall opening with the tube ends being exposed to different fluid pressures.

Claim 3
Dependent Claim
