Abstract
The utility model discloses a novel copper cladding on iron conducting bolt which comprises a conducting bolt body, and the conducting bolt body is composed of a nut and a stud. A hole along the axis of the conducting bolt body is formed in one end close to the nut of the conducting bolt body, a conducting copper cylinder is arranged in the hole, and the depth of the hole is 1/4 to 1/2 of the length of the conducting bolt body. The conducting bolt body is made of metal iron materials, the hole is molded by one time cold heading, and by adding welding filter metal, the hole is connected with the conducting copper cylinder in a welding mode. The novel copper cladding on iron conducting bolt has the advantages that practicability is good, the production cost is reduced and is low, use and installation are convenient, good conductivity is guaranteed, and the torque power of the thread on the stud is guaranteed as well.
Description
Technical field
The utility model relates to a kind of electric installation, particularly a kind of novel iron copper-clad conducting bolt.
Background technique
For the connection of circuit and to transmit large electric current convenient, on a lot of electrical equipments, all can use conducting bolt, as everyone knows, metallic copper is good conductive material, resistance is little, the energy using electricity wisely, but the expensive of copper also is undisputable fact, existing conducting bolt is in order to conduct electricity very well, substantially all adopt copper material to make, and this has also just increased the cost of production, use, also increased the price of corresponding product on the market, in addition, the fine copper material is lower than iron hardness, and bolt tooth line assembling torque force does not reach higher requirement.
The model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of novel iron copper-clad conducting bolt is provided.
To achieve these goals, the utility model institute Adopts measure:
A kind of novel iron copper-clad conducting bolt comprises the conducting bolt body that is comprised of nut and double-screw bolt, and described conducting bolt body has along its axial hole near an end of nut, is provided with conduction copper column in the hole;
The degree of depth in described hole the conducting bolt body length 1/4～1/2 between;
Described conducting bolt body is that the metallic iron material is made;
Described hole adopts a cold-heading molding to form, and adds welding filler metal between hole and the conduction copper column and is welded to connect.
The beneficial effects of the utility model: practicality, reduced cost of production, cost of production is low, and use, easy for installation when guaranteeing to conduct electricity very well, has guaranteed screw thread moment of torsion intensity of force on the double-screw bolt.

Embodiment
A kind of novel iron copper-clad conducting bolt comprises the conducting bolt body that is comprised of nut 1 and double-screw bolt 2, and described conducting bolt body has along its axial hole 4 near an end of nut 1, is provided with conduction copper column 3 in the hole 4; The degree of depth in described hole 4 the conducting bolt body length 1/4～1/2 between; Described conducting bolt body is that the metallic iron material is made; Described hole 4 adopts a cold-heading molding to form, and adds welding filler metal between hole 4 and the conduction copper column 3 and is welded to connect.
Use the time of the present utility model, the conducting bolt body has along its axial hole 4 near an end of nut 1, be provided with conduction copper column 3 in the hole 4, the degree of depth in described hole 4 the conducting bolt body length 1/4～1/2 between, when assurance conducts electricity very well, guaranteed screw thread moment of torsion intensity of force on the double-screw bolt, because iron is harder than copper; Described conducting bolt body is that the metallic iron material is made; Described hole 4 adopts a cold-heading molding to form, and adds welding filler metal between hole 4 and the conduction copper column 3 and is welded to connect, and cost of production is low, and is easy to use, thereby realized the purpose of this utility model.
Those skilled in the art's simple change and replacement in related domain all are within the protection domain of the present utility model.
