Abstract
The utility model discloses a copper-aluminum transition connection terminal adopting the compression joint, which comprises a terminal main body, wherein, the terminal main body is a tube body made of aluminum; an extension board is arranged at one end of the tube body made of aluminum; a punched hole is formed on the extension board; copper-aluminum composite cushion covers matched with each other are respectively installed at the upper and the lower ends of the punched hole in a pressing manner; and the copper-aluminum composite cushion covers are fixedly connected with the terminal main body through bolts. The copper-aluminum transition connection terminal has the characteristics of simple structure, convenient installation and use, low copper consumption, low manufacture cost and the like.
Description
Technical field:
The utility model relates generally to the manufacturing of splicing ear between a kind of copper aluminium, relates in particular to and a kind ofly adopts the compound cushion cover of explosive welding copper aluminium, as the copper-aluminium transition power circuit splicing ear of adaptor.
Background technology:
Demand for copper-aluminium transition connects is present in the industry-by-industry field, as: industry fields such as electrolytic aluminium, cathode copper, chlor-alkali, oil, chemical industry, electric power and transmission of electricity, power transformation, power equipment.
Be example now with electric power and power equipment industry:
In traditional electric power and the power equipment industry, it mainly is to realize by copper to aluminum adapter bar, copper-aluminium transition wire clip and copper al wiring terminal that copper-aluminium transition connects, being connected of copper to aluminum adapter bar, copper-aluminium transition wire clip and copper al wiring terminal copper and aluminium itself generally adopts flash welding, friction welding (FW), soldering connection method to realize, usually, the composition surface is difficult to realize metallurgical binding completely, the percent defective height, bond strength is low, copper material consumption is big, occur phenomenon of rupture easily, and can cause equipment and power transmission and transformation line failure rate height; As seen, still there are problems such as the copper consumption is big, manufacturing cost is high, industrialization degree is low, on-the-spot use inconvenience in copper al wiring terminal.
The utility model content:
The purpose of this utility model is in order to remedy the deficiency of prior art; provide a kind of employing crimping to connect the copper-aluminium transition splicing ear; problems such as the copper consumption is big, manufacturing cost is high, industrialization degree is low, on-the-spot use inconvenience have been solved; have manufacturing process uniqueness, characteristics such as simple to operation, with low cost; guarantee the on-the-spot versatility of installing and using simultaneously, can carry out large-scale production.
The utility model is achieved through the following technical solutions:
A kind of employing crimping connects the copper-aluminium transition splicing ear, include terminal bodies, it is characterized in that: described terminal bodies is the aluminum body, one end of described aluminum body is provided with extension board, described extension board is provided with punching hole, the upper and lower side of described punching hole is pressed with the compound cushion cover of copper aluminium that cooperatively interacts respectively, the compound cushion cover of described copper aluminium is the copper coin layer of one by explosive welding, aluminum layer is formed, and the sleeve pipe that the middle part of the compound cushion cover of copper aluminium has the flange punching press to form, the aluminum layer of the compound cushion cover of described copper aluminium and the punching hole inwall on the extension board are fitted, there is bolt to pass sleeve pipe in the compound cushion cover of copper aluminium, and connects by fixed by nut; The copper layer of the compound cushion cover of described copper aluminium toward the outer side.
Described a kind of employing crimping connects the copper-aluminium transition splicing ear, and it is characterized in that: its copper layer thickness of the compound cushion cover of described copper aluminium is that 0.1-3.0mm, aluminum layer thickness are 0.1-5.0mm, and the compound cushion cover integral thickness of copper aluminium is 0.2-5.0mm.
The utility model adopts the copper aluminium composite pad cover pressing of explosive welding combination to connect, not only few, the low cost of manufacture of copper material use amount, forever can not come off, and have versatility, can carry out large-scale production.In electric power and power equipment industry, this technology singly is not applicable to the manufacturing and the method for attachment of " terminal " between copper aluminium, also be applicable to copper silver, copper gold, aluminium silver, etc. " terminal " of other intermetallic combining forms make and be connected.
The utility model has the advantages that:
The utlity model has simple in structure, easy to install, characteristics such as the copper consumption is little, low cost of manufacture, also have the versatility of installing and using simultaneously, the manufacturing process uniqueness, characteristics such as industrialization degree height can be carried out large-scale production.
