Classification: CPC E  H | IPC H

Claim 0:
1. An electrical feedthrough assembly, comprising:
a lower assembly having a first end and a second end, wherein the lower assembly comprises:
an outer body with a lower housing and an upper housing disposed within a bore of the outer body,
wherein the lower housing extends axially outward from the outer body of the lower assembly to form the first end,
wherein the upper housing extends axially outward from the outer body of the lower assembly to form the second end, and
a first conductor extending from the lower housing to the upper housing, wherein at least one portion of the first conductor is enclosed in a first insulator; and

an upper assembly having a first end and a second end, wherein the upper assembly is coupled to the lower assembly, wherein the upper assembly comprises:
an outer body with a pin end at the first end, wherein the pin end is inserted into an opening at the second end of the lower assembly,
a main body connected to the outer body of the upper assembly,
a second conductor disposed within the main body, wherein at least one portion of the second conductor is enclosed in a second insulator,
a channel in the outer body of the upper assembly open to an outside of the outer body of the upper assembly and a chamber within the outer body of the upper assembly,
a piston disposed within the channel and configured to fluidly isolate the chamber from the outside of the outer body of the upper assembly,
a shuttle pin provided within the outer body of the upper assembly configured to move axially between an upper position at least partially within the chamber and a lower position proximate the pin end, and
a dielectric fluid provided within the chamber,

wherein the piston is movable within the channel in response to a pressure differential between the dielectric fluid and the outside of the outer body of the upper assembly, such that the first conductor is conductively connected to the second conductor.
