A new type of vehicle fuse base

Abstract

The invention relates to the technical field of automobile electrical appliances, in particular to a new type of fuse base for automobiles, including a lower cover, a connecting part, a connecting hole, a connecting column, a baffle, a clip, a buckle, an elastic pad, a spacer, a protruding part, Limiting column, annular card groove, tapered groove, notch, tapered shaft, screw rod, screw hole. The beneficial effects of the present invention are as follows: the through holes on the fuse are engaged in the annular slots of the two limit posts respectively, and then the cone shaft is rotated by an external tool, and the thread of the screw rod and the screw hole is screwed together to drive the cone shaft in the cone Sliding in the groove, and expand the limit column to the radial outside, so that the inner wall of the annular card groove is pressed against the through hole of the fuse. Since the tapered groove has a vertical upward force on the tapered shaft, the screw and the screw hole can be formed. Anti-loosening, thereby ensuring that the tapered shaft will not slide in the tapered groove, so that the annular card groove can always be pressed against the inner wall of the through hole of the fuse, and the stability after installation is improved.

Description

technical field [0001] The invention relates to the technical field of automobile electric appliances, in particular to a novel fuse base for automobiles. Background technique [0002] Automotive fuses generally include midi and mega fuses. At present, the mega fuse is connected to the lower cover of the fuse base as follows: a screw and a nut are provided on the lower cover, and a through hole matching the screw is provided at both ends of the length of the mega fuse. Insert the through hole on the mega fuse into the screw, and then limit it on the screw through the nut, so that the mega fuse can be installed, but this installation method has the following defects: that is, when the thread on the screw is in contact with the mega fuse for a long time , Under the action of arc, it is easy to be burned out, which will cause the thread to fail, thus affecting the normal screwing of the nut on the thread, which may cause the mega fuse to be unable to be limited by the nut, maki...

[0002] Automotive fuses generally include midi and mega fuses. At present, the mega fuse is connected to the lower cover of the fuse base as follows: a screw and a nut are provided on the lower cover, and a through hole matching the screw is provided at both ends of the length of the mega fuse. Insert the through hole on the mega fuse into the screw, and then limit it on the screw through the nut, so that the mega fuse can be installed, but this installation method has the following defects: that is, when the thread on the screw is in contact with the mega fuse for a long time , under the action of electric arc, it is easy to be burned out, which will cause the thread to fail, thus affecting the normal screwing of the nut on the thread, which may cause the mega fuse to be unable to be limited by the nut, making it in an unstable state
