Abstract
A hermetic or semi-hermetic terminal assembly having a cup-shaped body portion with a generally flat bottom wall and at least one opening in the bottom wall defined by an annular lip extending into the cup. One current conducting pin extends through each opening and beyond the lip on both ends of the body portion, the inner end of the pin being on the dish side of the cup-shaped body portion, and the outer end on the outer side of the body. A resilient plastic material is molded into place within the body portion to bond the pin to an inside surface of the lip with a hermetic seal. The plastic extends beyond the face of the body portion and bonds to the pin to provide the desired air path between the respective pins and each other and/or the face of the body portion.
Claims21
A hermetic terminal assembly comprising:
- a metallic body, said body having a bottom portion and a side wall, said bottom portion having and interior surface and an exterior surface and at least one opening there through;
- a current conducting pin extending longitudinally through said opening in said bottom portion;
- a dielectric plastic resin mechanically interlocked with said body and covering at least portions of both said interior surface and said exterior surface of said bottom portion of said body, said plastic resin bonding to both said body and said pin and providing a seal between said pin and said opening in said bottom portion through which said pin is extending.
A terminal assembly comprising:
- a metallic body, said body having a side wall and bottom peripheral lip extending inwardly toward a longitudinal center of said body from said side wall, said peripheral lip having an interior surface and an exterior surface and defining a longitudinal opening through said body;
- a plurality of current conducting pins extending longitudinally through said opening of said body;
- a dielectric plastic resin mechanically interlocked with said body and covering at least portions of both said interior surface and said exterior surface of said bottom peripheral lip of said body, said plastic resin bonding to both said body and each of said pins, and providing a seal between each of said pins and said opening in said bottom portion through which said pin is extending.
