Abstract
Disclosed is an insulative header assembly with electrical feed through terminals therein. The header includes at least one tapered opening therethrough. A depression or counterbore at the narrow end of the tapered opening forms a shoulder therewith. A metallic one-piece feedthrough terminal with a tapered portion is forced into the tapered opening tightly enough to form a seal therewith. Part of the tapered portion extends into the recess or depression. The metal in the depression is flared to overlap the shoulder and thus securely fix the terminal in place. There are splines in the depression, and the metal that is forced into the depression conforms to the shape of the splines and thus rotatably restrains the terminal in the header.
Claims24
In combination, a header assembly comprising:
- a disc-like header made of insulating material and having a slightly tapered opening projecting transversely therethrough, the narrow end of said tapered opening having a depression formed therein and defining a shoulder, said depression including a peripheral row of axial spline means;
- a one-piece metal feed through terminal pressed into said opening, said terminal having a tapered portion which is fitted into said tapered opening tightly enough to form a seal therewith, said terminal extending at least into said depression;
- said terminal being formed of a material which is softer than the material of said header so that when pressed into said opening said terminal conforms to irregularities in said opening to enhance the seal;
- and
- at least a portion of the part of said terminal that is within said depression being flared so that said portion overlaps said shoulder and conforms with said spline means.
A header assembly for capacitors comprising, in combination, a header of insulating material and at least two feed through terminals;
- said header defining two substantially parallel surfaces and having at least two slightly tapered openings projecting transversely therethrough, the narrow end of each of said openings terminating at separate depressions in one of said surfaces, each of said depressions forming a shoulder around the associated narrow end and defining peripheral spline means;
- a separate one-piece metal feed through terminal pressed into the each of said openings, each of said terminals having a tapered portion which is fitted into the associated tapered opening tightly enough to form a seal therewith, each of said terminals extending at least into the associated depression;
- each of said terminals being formed of a material which is softer than the material of said header so that when pressed into the associated opening each of said terminals conforms to irregularities in said opening to enhance the seal;
- and
- at least a portion of the part of each terminal that is within the associated depression being flared so that said portion overlaps the associated shoulder and conforms with said spline means.
