Problems solved by technology

Because the assembly torque of the M5 screw is too large, and the material of the positive plate is aluminum alloy with a thickness of only 4mm, it is easy to cause the M5 threaded hole to slip when the screw is fastened, resulting in the scrapping of the rectifier

Abstract

The invention discloses a screw structure for automobile rectifier current output, comprising a positive plate and an M5 metal nut. The screw structure is characterized in that the M5 metal nut is fixed on the positive plate in the mode of straight line extrusion, and the M5 metal nut and the positive plate form a whole. The invention has the advantages that the torsional strength of the metal nut can completely satisfy the requirement on screw tightening torque and also guarantees the stability and the reliability of generator current output.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to a screw structure for current output of an automobile rectifier. Background technique [0002] At present, the existing automotive rectifiers all use Japanese Hitachi series rectifiers. The input end of the electrical equipment is mainly fixed on the positive plate through a screw, and the positive plate fixes the screw with an M5 threaded hole. Since the assembly torque of the M5 screw is too large, and the material of the positive plate is aluminum alloy with a thickness of only 4mm, it is easy to cause the M5 threaded hole to slip when the screw is tightened, resulting in scrapping of the rectifier. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a threaded structure for the current output of an automobile rectifier. This structure can increase the torsional strength of the M5 thread and ensure th...
