Problems solved by technology

However, the existing connection terminal structure is unreasonable, and there are many safety hazards
For example, the existing connection terminal is formed by friction welding of copper strips and aluminum strips. In this way, the copper-aluminum joint angle surface is small, and the contact surface resistance will be large. During long-term use, when the equipment is running, overloaded or short-circuited, the copper The aluminum connection will heat up rapidly, which may cause a power outage d

Example Embodiment

[0029] In order to facilitate those skilled in the art to better understand the present invention, the present invention will be further described with reference to the following embodiments:

[0030] The method for preparing a copper-aluminum composite terminal of the present invention has specific steps as follows:

[0031] The first step is to choose to prepare a copper-clad aluminum bimetallic composite solid rod. This copper-clad aluminum bimetallic composite solid rod can be obtained through market purchase. The specific requirements are: A. The copper-aluminum bonding rate is above 85%. It determines the conductivity and yield of the final finished copper-aluminum composite terminal. For example, if the copper-aluminum adhesion rate is too low, the final finished copper-aluminum composite terminal has poor conductivity, and the copper-aluminum layer may be separated during processing. This phenomenon leads to a decrease in the yield rate; B. The thickness of the copper layer...

Abstract

The invention belongs to the technical field of connecting terminals and relates to a manufacturing method of a copper-aluminum composite terminal and the composite terminal manufactured thereby. The manufacturing method comprises the steps of preparing materials, punching the materials, punching a fixed mounting hole of a conducting wire, turning a round corner, press-molding, finishing, punching, coating a protective agent, coating electric force compounded grease and the like; and the copper-aluminum composite terminal manufactured by the method comprises the cylindrical end and the flat end which are mutually connected, and each end consists of an aluminum layer and a copper layer stuck on the aluminum layer, thereby effectively solving the shortcomings and the defects of easy rupture and easy corrosion in a copper-aluminum solder terminal in the prior art and improving the overall quality of the copper-aluminum composite terminal.

Description

Technical field: [0001] The invention belongs to the technical field of connecting terminals, in particular to a method for preparing a copper-aluminum composite terminal, and also relates to a copper-aluminum composite terminal prepared by the method. Background technique: [0002] With the continuous development of the electric power industry, the use of electrical connection devices such as electrical connection terminals has increased significantly, and the quality of electrical connection terminals directly affects the safety of power systems and equipment. The terminals of most existing equipment are made of copper materials, and the wires are mostly made of aluminum materials, so most of the existing electrical connection terminals also use copper-aluminum connection terminals. However, the structure setting of the existing connecting terminals is unreasonable, and there are many potential safety hazards. For example, the existing connection terminal is formed by fri...
