Abstract
A switching and protection device for high-voltage onboard electrical systems having a DC-voltage switch and a fuse, wherein the DC-voltage switch includes a housing, at least two fixed contacts, and a bridge designed to be movable with respect to the fixed contacts, wherein the bridge is formed from an electric insulator, wherein two contacts are arranged on the bridge such that, during a movement of the bridge in the direction of the fixed contacts, the two contacts make contact with the fixed contacts, wherein the two contacts arranged on the bridge are electrically connected to each other via the fuse.
Claims14
A switching and protection device for high-voltage onboard electrical systems, the device comprising:
- a DC-voltage switch;
- and
- a fuse,
- wherein the DC-voltage switch includes a hermetically sealed housing, at least two fixed contacts penetrating from outside to inside of the hermetically sealed housing, and a bridge designed to be movable with respect to the fixed contacts, and
- wherein the bridge is formed from an electric insulator, wherein two bridge contacts are arranged on the bridge so that, during a movement of the bridge in the direction of the fixed contacts, the two bridge contacts make contact with the fixed contacts, wherein the two bridge contacts arranged on the bridge are electrically connected to each other via the fuse, wherein each of the bridge contacts includes a base extending from the bridge in a lateral direction and the fuse arranged farther from the base than the corresponding bridge contact orthogonal to the lateral direction.
A switching and protection device for high-voltage onboard electrical systems, the device comprising:
- a DC-voltage switch;
- and
- a fuse,
- wherein the DC-voltage switch includes a hermetically sealed housing, at least two fixed contacts, a bridge designed to be movable with respect to the fixed contacts, and a connection rod attached with the bridge, the bridge having a T-shape including a receiver attached with the connection rod,
- wherein the bridge is formed from an electric insulator, wherein two bridge contacts are arranged on the bridge so that, during a movement of the bridge in the direction of the fixed contacts, the two bridge contacts make contact with the fixed contacts, wherein the two bridge contacts arranged on the bridge are electrically connected to each other via the fuse.
A device for high-voltage onboard electrical systems, the device comprising:
- a DC-voltage switch;
- and
- a fuse wire,
- wherein the DC-voltage switch includes a hermetically sealed housing, at least two fixed contacts, a bridge formed from an electrical insulator and movable with respect to the fixed contacts, and a connection rod attached with the bridge, the bridge having a T-shape for attachment with the connection rod,
- wherein the bridge includes bridge contacts arranged thereon electrically connected with each other via the fuse wire, the bridge contacts arranged so that, during a movement of the bridge in the direction of the fixed contacts, the bridge contacts engage with the fixed contacts to provide electrical communication via the fuse wire.
A switching and protection device for high-voltage onboard electrical systems, the device comprising:
- a DC-voltage switch;
- and
- a fuse,
- wherein the DC-voltage switch includes a hermetically sealed housing, at least two fixed contacts, and a bridge designed to be movable with respect to the fixed contacts, and
- wherein the bridge is formed from an electric insulator, wherein two bridge contacts are arranged on the bridge so that, during a movement of the bridge in the direction of the fixed contacts, the two bridge contacts make contact with the fixed contacts, wherein the two bridge contacts arranged on the bridge are electrically connected to each other via the fuse,
- wherein the bridge includes a number of posts projecting therefrom in the direction of the fixed contacts, the two bridge contacts arranged spaced apart from the posts orthogonal to the direction of projection of the posts.
