Claims21
A module comprising:
- a hermetically sealed housing that includes in a hermetically sealed interior thereof a plurality of electrical components, and at least one electrical interconnect electrically connected to at least one of said components in said interior and extending to an exterior of said hermetically sealed portion with a stress relief collar disposed around and hermetically joined with said interconnect;
- and terminal block having a lead frame wherein said lead frame includes at least one lead having a first end electrically connected to said at least one interconnect and a free end adapted for external connection , wherein said stress relief collar is formed from a first material and a second material;
- said first material having a higher electrical resistively than said second material.
A module comprising:
- a hermetically sealed housing that includes in a hermetically sealed interior thereof a plurality of electrical components, at least one electrical interconnect electrically connected to at least one of said components in said interior and extending to an exterior of said hermetically sealed housing, and a stress-relief collar hermetically attached to and disposed around said interconnect, said hermetically sealed housing including a base, a plurality of walls hermetically attached to said base and defining boundaries of said interior and a lid hermetically attached to said plurality of walls, wherein said collar extends from said exterior of said hermetically sealed housing to said interior thereof.
A module comprising:
- a housing that includes a plurality of electrical components, and at least one electrical interconnect electrically connected to at least one of said components and extending to an exterior of said housing;
- and a terminal block portion having a lead frame wherein said lead frame includes at least one lead having a first end electrically connected to said at least one interconnect and a free end adapted for external connection, with a molded body disposed around said lead frame.
