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 comprising an interior surface, an outer surface and at least one opening having a wall;
- a current conducting pin extending longitudinally through said opening in said bottom portion;
- a monolithic dielectric plastic resin covering at least portions of each of said interior surface, said exterior surface, and said wall of said opening of said bottom portion of said body, said monolithic dielectric plastic resin bonding directly 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 a bottom peripheral lip defining an opening through said body, said peripheral lip extending inwardly toward a longitudinal center of said body from said side wall, said peripheral lip comprising an interior surface, an exterior surface and an longitudinally extending wall;
- a plurality of current conducting pins extending longitudinally through said opening of said body;
- a monolithic plastic resin covering at least portions of each of said interior surface, said exterior surface and said longitudinally extending wall of said bottom peripheral lip, said monolithic plastic resin bonding directly to both said body and said pin, and providing a seal between said pins and said opening in said bottom portion through which said pins are extending.
