Abstract

The invention discloses a high-strength conductive bolt that is not easy to fall off, which includes a screw rod and a nut. , a concave groove is connected between the conductive copper column and the screw rod, the screw rod includes an upper screw rod and a lower screw rod, an arc-shaped recess is arranged between the upper screw rod and the lower screw rod, and the depth of the hole is about 100% of the length of the screw rod Between 1/4-1/2, the screw is made of iron material, the screw is formed by cold heading, and the upper end of the screw, nut and conductive copper column is provided with a heat-insulating and high-temperature-resistant coating layer, the outer surface of the screw is provided with threads, and the conductive copper column is made of corner copper material. The invention has the characteristics of simple and reasonable structure, high practicability, low cost and high practicability.

Description

technical field [0001] The invention belongs to the technical field of fasteners, and in particular relates to a high-strength conductive bolt. Background technique [0002] Now, there are many places in the industrial field that need to use bolts for fastening and loosening, but when ordinary bolts are subjected to strong vibrations, the bolts are likely to fall off. Conductive bolts are common bolts. Existing conductive bolts, their bolts The head is inlaid with silver cadmium sheets. The production cost of this conductive bolt is very high, and cadmium is a metal banned by the European Union, which seriously pollutes the environment; moreover, the surface of the bolt head and the silver cadmium sheet needs to be pickled or galvanized during the production process After a long time of use, the silver cadmium sheet will be oxidized, and the contact resistance will increase, thereby reducing the electrical conductivity. With the wide application of bolts, the role of bolts i...
