Abstract
The utility model discloses a metal explosive welding copper-aluminium compound electrical binding clip, which comprises a copper sheet and an aluminium sheet folded into one body, the bonding surface of the copper sheet and the aluminium sheet adopts the explosive welding connection, and a connection hole is formed on the copper sheet and the aluminium sheet folded into one body. The compound electrical binding clip is characterized in that the copper sheet and the aluminium sheet are folded into one body, the connection holes on the copper sheet and on the aluminium sheet are in the same position, and the compound electrical binding clip adopts an atomic binding manner between the copper sheet and the aluminium sheet, therefore, the binding force is stronger, fracture can not occur on the compound surface, and the electric thermal conducting performance, and good plasticity and ductility of copper and aluminium are combined, the electric conductivity is high, the resistance ratio is lower, the application is not affected due to the environment, and the compound electrical binding clip can be widely applied in the occasions such as high and low voltage electrical equipments, electronic components, high and low voltage power transmission and transformation accessories, compound gaskets, and the like.
Description
Technical field
The utility model relates to a kind of electrical power wiring folder, particularly a kind of metallic explosive soldering copper aluminium composite electric binding clip.
Background technology
Traditional copper-aluminium transition wire clip generally adopts the two-period form structure, the one end is a copper coin, the other end is an aluminium sheet, adopt flash welding, friction welding (FW) connection between copper coin and the aluminium sheet, the composition surface is difficult to realize metallurgical binding completely, the percent defective height, its bond strength is low, copper material consumption is big, occurs phenomenon of rupture easily, causes the power transmission and transformation line fault.
The utility model content
The purpose of this utility model provides a kind of metallic explosive soldering copper aluminium composite electric binding clip, phenomenon of rupture can not occur, and electric conductivity is better.
In order to solve above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of metallic explosive soldering copper aluminium composite electric binding clip is characterized in that: include the copper sheet and the aluminium flake that are overlapped into one, described copper sheet adopts explosive welding to be connected with the aluminium flake faying face.
There is rolling arc groove described copper sheet and aluminium flake front portion.
On described copper sheet and the aluminium flake wiring hole is arranged.
Described copper sheet thickness is 0.8-1mm, and aluminium flake thickness is 1-20mm.
The utility model is a kind of stable performance conductivity height, be convenient to processing and forming and the electric conducting material of stable output performance is arranged, it is not subjected to the influence of environment for use, and amount of copper consuming only is advantages such as existing product 50%, and its electric property (as contact resistance, temperature rise) meets the requirement of GB GB2137-85 and GB 2314-85.
The utility model adopts copper sheet and aluminium flake iterative structure, wiring hole is positioned at same position on copper sheet and the aluminium flake, and is combining of atom between copper sheet and the aluminium flake, so adhesion is stronger, composite surface phenomenon of rupture can not occur, and combine copper and aluminium electricity heat conductivility and good plasticity and ductility, the conductivity height, resistance ratio is lower, use the influence that is not subjected to environment, be applicable to high and low voltage electrical equipment, electronic devices and components, high-low pressure power transmission and transformation accessory and Composition spacer etc.
