Electric power terminal feed-through

An electric power terminal feed-through comprising:

• a metallic body comprising:
• an outer cylindrical sidewall having a first end and a second end, an annular lip extending from the second end of the outer cylindrical sidewall, an inner cylindrical sidewall, and a connecting wall connecting the inner cylindrical sidewall to the first end of the outer cylindrical sidewall;
• at least one current conducting pin extending through the metallic body;
• and a seal sealing the pin to the metallic body, the seal disposed within an opening defined by the inner cylindrical sidewall;
• wherein the inner cylindrical sidewall and the outer cylindrical sidewall define a gap therebetween.

An electric power terminal feed-through comprising:

• a cylindrical sidewall located in an opening of a housing;
• at least one current conducting in extending through the cylindrical sidewall;
• a seal sealing the at least one in to the cylindrical sidewall;
• an annular lip extending radially and outwardly from the cylindrical sidewall to form an angle of about ninety degrees relative to the cylindrical sidewall;
• and
• an annular protrusion extending from the annular lip toward the housing and welded to the housing, the annular protrusion stamped from the annular lip so that an annular groove is formed at the annular lip opposing the annular protrusion,
• wherein an air gap is defined between the annular protrusion, the annular lip, the cylindrical sidewall, and the housing.

An electric power terminal feed-through adapted to be installed to a housing, comprising:

• a metallic body including a cylindrical sidewall and an annular lip, the annular lip extending outwardly from an end of the sidewall to form an acute angle relative to the sidewall and such that the annular lip engages the housing at a location away from the sidewall;
• at least one current conducting pin extending through the metallic body;
• and a seal sealing the in to the metallic body;
• wherein the annular lip comprises a distal end opposite to a transition portion of the sidewall and a contacting area between the distal end and the transition portion of the side wall, the contacting area adapted to engage the housing.

An electric power terminal feed-through adapted to be installed to a housing, comprising:

• a metallic body including a cylindrical sidewall, an annular lip, and a curved portion between an end of the sidewall and the annular lip;
• the annular lip extending outwardly from the end of the sidewall to form an acute angle relative to the sidewall and such that the annular lip engages the housing at a location away from the sidewall;
• at least one current conducting pin extending through the metallic body;
• and a seal sealing the pin to the metallic body, wherein the annular lip comprises a distal end opposite to the end of the sidewall, the distal end adapted to engage the housing.
