Claim 16

In a hermetic refrigeration terminal having a cup-shaped body with a generally flat bottom and at least one opening in said bottom defined by an annular sealing lip, a current conducting pin extending through said opening and beyond said lip on both ends thereof, the inner end of said pin being on the dish side and the outer end, on the outer side of said body, and a seal bonding said pin to an inside surface of said lip , a flange extending generally radially from said pin and located axially between said lip and said inner end of said pin, and a sleeve surrounding said pin and extending axially between said flange and said lip, said sleeve being at least in part larger in diameter than said opening, said sleeve being bonded at its end opposite the flange to said seal, the improvement comprising said pin's being coated beyond the part of its reach in which it is bonded to said seal with a material different from said pin, said pin being enlarged in transverse cross-sectional area through the axial reach in which it is bonded to said seal relative to the cross-sectional area of the inner and outer ends beyond the reach of said enlarged part.

Claim 17

The improvement of claim 14 wherein said flange is non-circular.

Claim 18

The improvement of claim 14 wherein the bottom of the cup-shaped body is provided with a plurality of openings defined by annular sealing lips, each having one of said pins extending through it and one of said sleeves extending around said pin, all of said sleeves being joined by a common web.

Claim 19

In a hermetic refrigeration terminal having a cup-shaped body with a generally flat bottom and at least one opening in said bottom defined by an annular sealing lip, a current conducting pin extending through said opening and beyond said lip on both ends thereof, the inner end of said pin being on the dish side and the outer end, on the outer side of said body, and a seal bonding said pin to an inside surface of said lip, a flange extending generally radially from said pin and located axially between said lip and said inner end of said pin, and a sleeve surrounding said pin and extending axially between said flange and said lip, said sleeve being at least in part larger in diameter than said opening, said sleeve being bonded at its end opposite the flange to said seal, the improvement comprising said bottom of the cup-shaped body's being ; provided with a plurality of openings defined by annular sealing lips, each having one of said pins extending through it and one of said sleeves extending around said pin, all of said sleeves being joined by a common web.

Claim 20

In a hermetic refrigeration terminal having a cup-shaped body with a generally flat bottom and at least one opening in said bottom defined by an annular sealing lip, a current conducting pin extending through said opening and beyond said lip on both ends thereof, the inner end of said pin being on the dish side and the outer end, on the outer side of said body, and a seal bonding said pin to an inside surface of said lip, a flange extending generally radially from said pin and located axially between said lip and said inner end of said pin, and a sleeve surrounding said pin and extending axially between said flange and said lip, said sleeve being at least in part larger in diameter than said opening, said sleeve being bonded at its end opposite the flange to said seal, the improvement comprising said bottom of the cup-shaped body's being ; provided with a plurality of openings defined by annular sealing lips, each having one of said pins extending through it and one of said sleeves extending around said pin, all of said sleeves being joined by a common web.
