ABSTRACT:
A receptacle for replaceably holding a replaceable fuse in an electrical circuit includes a forwardly inwardly tapered tubular member closed at its front end by a contact-defining metal cap and provided at its rear end with an internally threaded enlarged section, a contact-defining metal collar telescoping the rear of the tapered tube forward of the enlarged section and having a terminal tab projecting outwardly through an opening in the enlarged section. An externally threaded closure plug separably engages the tubular member threaded section and has in its front face a well whose axis is transversely offset from the plug axis and whose peripheral face is rearwardly inwardly tapered. A transversely crescent shaped wedge member projects forwardly from the well border and is integrally formed with the plug and has a tapered inside face coplanar with the well peripheral face.
