发明名称 Fuse with insulated plugs
摘要 An improved fuse including a fuse body formed of an electrically insulative material. The fuse body defines a cavity which extends from a first end of the fuse body to a second end of the fuse body. A fusible element is disposed within the cavity and extends from a first end face of the first end of the fuse body to a second end face of the second end of the fuse body. Insulated plugs are disposed within the cavity at the first and second ends of the fuse body wherein the plugs adhere to an interior surface of the fuse body and form seals that close the internal cavity. The fuse may further include end terminations that are applied to the ends of the fuse body in electrical contact with the fusible element.

主权项 1. A fuse comprising: a fuse body formed of electrically insulative material defining a cavity extending longitudinally from a first end of the fuse body to a second end of the fuse body; a fusible element disposed within the cavity and extending from a first end face of the fuse body at the first end to a second end face of the fuse body at the second end; first and second insulated plugs bonded to an interior surface of the fuse body at the first and second ends, respectively, wherein the first and second insulated plugs seal respective ends of the cavity; wherein a first portion of the fusible element proximate the first end of the fuse body extends between the first insulated plug and the interior surface of the fuse body with a first end of the fusible element protruding from the cavity, the first end of the fusible element engaging and terminating at the first end face of the fuse body; wherein a second portion of the fusible element proximate the second end of the fuse body extends between the second insulated plug and the interior surface of the fuse body with a second end of the fusible element protruding from the cavity, the second end of the fusible element engaging and terminating at the second end face of the fuse body; first and second end terminations covering the first and second ends of the fuse body, respectively, the first end termination being in electrical contact with the fusible element at the first end face and the second end termination being in electrical contact with the fusible element at the second end face; and first and second metalized coatings disposed on the first and second end faces of the fuse body, respectively, in electrical contact with respective ends of the fusible element for facilitating electrical connections between the fusible element and the first and second end terminations; wherein the first and second insulted plugs extend through the first and second metalized coatings, respectively, and engage the first and second end terminations, respectively.
