Embodiment Construction

[0026] The present invention will now be described more fully below with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art. In the drawings, the same reference numerals always refer to the same elements.

[0027] Figure 1A An exploded perspective view of an exemplary fuse 10 according to the present disclosure is shown. The fuse 10 includes a fuse body 20 that defines a cavity 25 that extends from a first end face 26-A to a second end face 26-B. The shape of the fuse body 20 may be, for example, rectangular, cylindrical, triangular, etc., with various cross-sectional configurations. The fuse ...

Abstract

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.

Description

Technical field [0001] The embodiments of the invention relate to the field of circuit protection devices. More specifically, the present invention relates to a fuse having an insulating plug that seals a cavity formed in the fuse body and helps to extinguish an arc when an overcurrent condition occurs. Background technique [0002] Fuses are used as circuit protection devices and form electrical connections with components in the circuit to be protected. One type of fuse includes a fusible element arranged in a hollow fuse body. When a specified fault condition (such as an overcurrent condition) occurs, the fusible element melts or otherwise disconnects to interrupt the circuit path and protect the protected electrical component or circuit from possible damage. Such fuses can be characterized by the amount of time required to respond to overcurrent conditions. In particular, fuses including different fusible elements respond with different operating times, because different f...
