Abstract
Electrical feedthroughs for battery housings are presented. The electrical feedthroughs include a connector, a ceramic insulator, and a terminal. A first seal couples the connector to the ceramic insulator via a first braze alloy. A second seal couples the ceramic insulator to the terminal via a second braze alloy. The electrical feedthroughs can also include a spacer. A first seal couples the connector to the ceramic insulator; a second seal couples the ceramic insulator to the spacer; and the third seal couples the spacer to the terminal. The first seal, the second seal, and the third seal include, respectively, a first braze alloy, a second braze alloy, and a third braze alloy.
Claims7
An electrical feedthrough, comprising:
- a ceramic insulator;
- a connector for coupling the ceramic insulator to a housing;
- wherein the connector comprises a cylindrical body with a central opening for receiving the ceramic insulator, the connector further comprising a lip surrounding the cylindrical body, the lip comprising an inner surface for bonding to the housing;
- wherein the housing has a thickness that is less than a thickness of the connector;
- a terminal disposed within the ceramic insulator;
- a first seal coupling the ceramic insulator to the connector, the first seal formed of a first braze alloy capable of bonding the ceramic insulator and the connector;
- and
- a second seal coupling the ceramic insulator to the terminal, the second seal formed of a second braze alloy capable of bonding the ceramic insulator and the terminal.
