Sealed bulkhead electrical feed-through positioning control

A data storage device comprising:

• at least one recording medium;
• an electrical feed-through including:
• a main body;
• a first positioning protrusion extending from the main body in a first direction;
• a second positioning protrusion extending from the main body in a second direction;
• a plurality of first electrical terminals positioned on a first side of the main body;
• a plurality of second electrical terminals positioned on a second side of the main body, the second side being substantially opposite the first side;
• and
• a plurality of vias electrically connecting at least some of the first electrical terminals with corresponding second electrical terminals through the main body;
• and
• an enclosure base with which the electrical feed-through is configured to be coupled, the enclosure base including:
• an aperture encompassed by the electrical feed-through;
• a first recessed positioning surface in a top portion of the enclosure base and extending in the first direction away from the aperture, such that the first positioning protrusion is configured to contact the first recessed positioning surface, wherein the top portion of the enclosure base is closer to the at least one recording medium than a bottom portion of the enclosure base opposite the top portion;
• and
• a second recessed positioning surface in the top portion of the enclosure base and extending in the second direction away from the aperture, such that the second positioning protrusion is configured to contact the second recessed positioning surface.

• and
• an enclosure base with which the electrical feed-through is configured to be coupled, the enclosure base including:
• an aperture;
• an annular recessed surface surrounding the aperture, wherein the annular recessed surface is in a top portion of the enclosure base that is closer to the at least one recording medium than a bottom portion of the enclosure base opposite the top portion;
• and
• at least one recess including a recess positioning surface at a shallower depth than the annular recessed surface and extending in a direction away from the annular recessed surface;
• and
• wherein each positioning protrusion of the electrical feed-through is configured to be received by a recess of the enclosure base, such that a position of the electrical feed-through is constrained in a direction substantially perpendicular to the recess positioning surface of the recess.
