Abstract
A feedthrough arrangement includes a titanium alloy terminal for conducting electrical current between a first environment within a housing and a second environment outside of the housing. An insulating member is positioned around a portion of the terminal. A sleeve member is positioned around the insulating member. The terminal, insulating member, and insulating member all being in sealing engagement therewith to environmentally isolate the first and second environments.
Claims36
A feedthrough arrangement, comprising:
- a titanium alloy terminal for conducting electrical current;
- an insulating member positioned around a portion of the terminal, the insulating member being in sealing engagement therewith;
- and
- a sleeve member positioned around the insulating member, the sleeve member being in sealing engagement with the insulating member.
A housing having an opening and including a first environment within the housing, comprising:
- a feedthrough arrangement, wherein the feedthrough arrangement includes:
- a titanium alloy terminal for conducting electrical current between the first environment within the housing and a second environment outside of the housing;
- an insulating member positioned around a portion of the terminal and in sealing engagement therewith;
- and
- a sleeve member positioned around the insulating member and in sealing engagement with the insulating member, the sleeve member being coupled to the housing at the opening thereof.
A method for providing environmental isolation between a first environment within a housing and a second environment outside of the housing, comprising:
- providing a titanium alloy terminal for conducting electrical current between the first environment and the second environment;
- providing an insulating member positioned around a portion of the terminal and in sealing engagement therewith;
- and
- providing a sleeve member positioned around the insulating member and in sealing engagement with the insulating member, the sleeve member being coupled to the housing at an opening thereof.
An apparatus, comprising:
- a titanium alloy terminal for conducting electrical current between a first space within a container and a second space outside of the container;
- an insulating member positioned around a portion of the terminal and in sealing engagement therewith;
- and
- a sleeve member positioned around the insulating member and in sealing engagement with the insulating member;
- wherein the insulating member isolates the first and second spaces.
