Metal housing part and method for maufacturing the housing part
A metal housing part having multiple through openings, a glass filling being situated in each of the openings, each glass filling closing an opening hermetically sealed and enveloping a contact end, which extends through the opening and the glass filling and whose two ends protrude out of the glass filling and the opening, and to a method for manufacturing the metal housing part. The housing part is configured as trough-shaped, having a base wall, side walls, and a flange. Because of the trough-shaped design, the housing part maintains its original shape even when the housing part is subjected to high temperatures.
1. A metal housing part, comprising:
contact pins; and
a metal housing arrangement having multiple through openings, the openings passing through a flange of the metal housing arrangement, wherein a glass filling is situated in each of the openings, each glass filling closing an opening, hermetically sealing it and enveloping a contact pin, which extends through the opening, the glass filling, and the flange, and whose two ends protrude out of the glass filling and the opening;
wherein the metal housing arrangement is configured as trough-shaped and includes:
a base wall;
side walls that extend upward at a periphery of the base wall, and at least a portion of which extend above a top of the base wall; and
the flange, the flange being exterior to the side walls and extending beyond, and in a plane higher than a top of, a periphery of the at least the portion of the side walls, and away from, the side walls.
2. The housing part of claim 1 , wherein each of two adjacent ones of the side walls form a right angle to one another.
3. The housing part of claim 1 , wherein the contact pins are in the flange.
4. The housing part of claim 1 , wherein the flange has a peripheral groove.
5. The housing part of claim 1 , wherein the flange has at least one second through opening.
6. The housing part of claim 1 , wherein at least one tab having a through opening is situated on the flange.
7. The housing part of claim 6 , wherein the tab has at least one tab part having a through opening, which is in a same plane as the base wall.
8. The housing part of claim 1 , wherein an extension of the flange at the top portion of the sidewalls forms a first step, and the flange includes a second step.
9. The housing part of claim 8 , wherein the flange includes two support parts situated in respective planes that are each perpendicular to planes in which the side walls are situated, and includes an intermediate part connecting the two support parts and situated in planes that are parallel to respective ones of the planes in which the side walls are situated.
10. The housing part of claim 9 , wherein the base wall and each of the support parts are situated in parallel planes.
11. The housing part of claim 1 , wherein the contact pins are of stainless steel.
