The mounting surface is abutted against, and the mounting surface and/or the conducting rod and the surface that the mounting surface is abutted against are embossing face.
Preferably, the base also includes the outlet copper bar for connecting external circuit, and the outlet copper bar passes through bolt
It is connected with the projection.
Preferably, the decorative pattern in the embossing face is uniformly arranged.
Preferably, the palmar density in the embossing face is 50~90 mesh/inch, and pattern depth is 5~30 microns.
Preferably, the surface that the concavo-convex depth of the embossing of the mounting surface is abutted against with the conducting rod with the mounting surface
Embossing concavo-convex depth it is identical.
Preferably, the embossing on the surface that the embossed shape of the mounting surface is abutted against with the conducting rod with the mounting surface
Shape matches.
Preferably, the melt also includes the copper fuse located at the body interior, the copper fuse and the conducting rod
Connection.
Compared to prior art, the fuse that the utility model is provided is by by the projection of the conducting rod of melt and base
A contact surface wherein side or two sides are set to embossing face, and contact therebetween can be made more stable, so that the melt
Contact with the outlet copper bar of the base is more reliable, reduces contact resistance, extends fuse service life.
