Embodiment Construction
[0055]In order to have a clearer understanding of the technical features, purpose and effects of the invention, the specific implementation of the present invention will now be described with reference to the accompanying drawings, and the same reference numerals in each figure represent parts with the same structure or function. The fuse base shown in the figure should not be understood as showing the actual structure of the fuse base or the actual proportion of the actual product, they are only used to illustrate the design solution of the present invention.
[0056] image 3 It is a three-dimensional structure diagram of a schematic embodiment of the fuse base of the present invention. As shown in the figure, the fuse base includes a mounting surface 10 and two first splicing surfaces 12 and second splicing surfaces 13 perpendicular to the mounting surface. Two mounting holes 102 (only one of which is schematically marked in the figure) are provided on the mounting surface...

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.
Description
technical field [0001] The invention relates to a fuse base and a fuse using the base, in particular to a fuse base and a fuse capable of multi-pole splicing. Background technique [0002] figure 1 A schematic diagram of an existing single pole size 00 fuse base is shown. As shown in the figure, two installation holes 102 are provided on the installation surface 10 of the base, and the two installation holes 102 are arranged along the longitudinal center 104 of the installation surface. The "longitudinal center" referred to in this article does not represent the symmetrical center in the geometric sense, it is only for the position of the mounting hole. A protrusion 52 is provided on the first splicing surface 12 perpendicular to the installation surface 10, and a groove 62 is arranged on the second splicing surface 13 perpendicular to the installation surface 10, and the shape of the protrusion 52 is opposite to the groove 62. . According to different design requirement...
