Abstract
The utility model provides a Cu-Al binding post for power transmission, which comprises an aluminum binding-post body, one end of which is tubular, another end is a flat plate. On the surface at one end of the flat plate part of the binding-post body, a copper-sheet layer is provided. The copper-sheet layer is tightly fit and fused with the corresponding flat plate part to become an integrated no-brazing-filler-metal structure. The utility model connects by fusing a copper-sheet layer on the aluminum binding-post body in an integrated way, the connection is reliable and will not drop off. The binding-post body has a high overall strength, will not collide and break. The no-brazing-filler-metal structure allows a small conducting resistance, low current-passing loss, improves power transmission efficiency and voltage withstanding capability of power transmission and transformation. A small amount of copper sheet is used in production, the consumption of copper is greatly reduced, and the cost is reduced.
Description
Technical field: the utility model relates to the copper al wiring terminal that a kind of electric power transfer connects usefulness.
Background technology: connect and during distribution is provided with, need use the binding post that the two ends conduction is respectively copper product and aluminum in electric power transfer.General copper al wiring terminal adopts the terminal body bottom of aluminum corresponding welding sheet material made of copper to constitute, and the copper material of consumption is more, the cost height, and the resistance of commissure is bigger when electric current passes through, and heating easily reduces the conduction transfer efficiency.And the copper al wiring terminal bulk strength of welding is lower, insecure, in connection is installed, aluminium and copper material part is collided in the commissure split, and the reliability of quality is not high.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of bulk strength height, the copper al wiring terminal that conducts electricity very well.
The utility model comprises the terminal body of aluminum, one end of this terminal body is the pipe shape, the other end is dull and stereotyped, is provided with the copper sheet layer on a side surface of terminal body plate part, and this copper sheet layer and corresponding plate part are close to the fusion formula of connecting as one does not have the solder structure.
The utility model one fusion on all-in-one-piece aluminum terminal body is connected with the copper sheet layer, connects reliably, can not come off, and the bulk strength height of terminal body can not collide fracture.No solder structure makes the resistance of conduction little, and it is few that electric current passes through loss, improved power transmission efficiency and power transmission and transformation resistance to pressure, and only produces and need use a small amount of copper sheet, has significantly reduced the consumption of copper material, has reduced cost.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the main structure schematic diagram of embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment: as shown in the figure, one end of the terminal body 1 of aluminum is the pipe shape, the other end is dull and stereotyped, is provided with copper sheet layer 2 on a side surface of terminal body 1 plate part, and this copper sheet layer 2 and corresponding plate part are close to the fusion formula of connecting as one does not have the solder structure.In the reality, generally on terminal body 1 plate part surface, be provided with copper sheet layer 2 place and also be provided with through hole 3, in the connection of some power equipments, use more convenient like this.
During use, the aluminium on the terminal body 1, copper part is connected with corresponding electrical power wiring end respectively, can conducts electricity transmission.Because the terminal body 1 of copper sheet layer 2 and aluminum is connected for no solder integral type fusion, electric conductivity is very good, the reliability height.
