Fuse base and fuse using the base

摘要

A fuse base and a fuse using the base comprise a mounting surface with two mounting holes disposed thereon; a first splicing face and a second splicing face perpendicular to the mounting surface, wherein the first splicing face is provided thereon with a first protrusion and a first groove, the second splicing face is provided thereon with a second protrusion and a second groove, the first protrusion is disposed at a position close to one mounting hole in the extension direction of the first splicing face, the second protrusion is also disposed at a position close to one mounting hole in the extension direction of the second splicing face, the first protrusion is opposite to the second groove in the direction perpendicular to the first splicing face, and the first groove is opposite to the second protrusion in the direction perpendicular to the second splicing face. The fuse bases and the fuses using the bases provided by the present invention can be spliced together into a multi-stage fuse as required when they are used with a melting piece of size 1, and can have an existing isolating plate bracket inserted into the groove on each side of the base and then have an isolating plate mounted onto the isolating plate bracket when they are used for melting pieces of size 2 and size 3.
