US 6,642,833 B2 · High-voltage current-limiting fuse

Abstract

A high-voltage current-limiting fuse comprises an elongated housing, an auto-centering connector centrally located about the elongated axis of the housing, and an elongated fusible element attached to the connector and secured along the elongated axis of the housing by the connector. The auto-centering connector is located about the elongated axis of the housing by a surface near one end of the housing, and the elongated conductive fusible element is connected to the connector and contained within the housing. The auto-centering connector is connected to an end of the fusible element, and mechanically located but electrically insulated relative to the housing.
