Abstract
Some embodiments include an apparatus, comprising: a partition; a feedthrough penetrating the partition and hermetically sealed to the partition, the feedthrough having a major axis; a first wall extending from the partition in a first direction along the major axis; and a second wall extending from the partition in a second direction opposite to the first direction along the major axis, the second wall forming a connector interface with the feedthrough; wherein a ratio of a length of the first wall to a thickness of the first wall is greater than or equal to 3:1.
Claims20
An apparatus, comprising:
- a partition;
- a feedthrough penetrating the partition and hermetically sealed to the partition, the feedthrough having a first longitudinal axis;
- a first wall extending from the partition in a first direction parallel to the first longitudinal axis;
- a second wall extending from the partition in a second direction opposite to the first direction and parallel to the first longitudinal axis, the second wall forming a connector interface with the feedthrough;
- and
- a vacuum enclosure;
- wherein:
- a ratio of a length of the first wall to a thickness of the first wall is greater than or equal to 3:1;
- the partition and the first wall are formed from a single, continuous material;
- and
- the first wall is configured to thermally isolate a hermetic seal between the partition and the feedthrough from a weld between the first wall and the vacuum enclosure.

An apparatus, comprising:
- a partition for supporting an electrical connection;
- a feedthrough for hermetically passing the electrical connection through the partition;
- a vacuum enclosure;
- and
- a first wall extending from the partition in a direction perpendicular to a longitudinal axis of the partition and hermetically connecting the partition to the vacuum enclosure at a weld, wherein:
- a ratio of a length of the first wall to a thickness of the first wall is greater than or equal to 3:1;
- the feedthrough is brazed to the partition;
- the first wall is welded to the vacuum enclosure;
- and
- the first wall is configured to thermally isolate the partition from the weld between the first wall and the vacuum enclosure.
