Abstract
The utility model provides a Cu-Al connection tube for power transmission, which comprises an aluminum tube body, both ends of which are blind. At the inner wall surface in the blind hole at one end of the tube body, a copper-sheet layer is provided. The copper-sheet layer is tightly fit fused with the corresponding inner wall to become an integrated no-brazing-filler-metal structure. The utility model connects by fusing way a copper-sheet layer on the aluminum tube body in an integrated way, and the connection is reliable and will not drop off. The tube 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 Cu-Al connecting pipe that a kind of electric power transfer connects usefulness.
Background technology: connect and during distribution is provided with, need use the tube connector that two ends are respectively copper product and aluminum in electric power transfer.General Cu-Al connecting pipe adopts aluminum pipe and copper pipe end correspondence to be welded to form, 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 tube connector bulk strength of welding is lower, insecure, in connection is installed, aluminum pipe and copper pipe 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 Cu-Al connecting pipe that conducts electricity very well.
The utility model comprises that two ends are equipped with the aluminum body of blind hole, is provided with the copper sheet layer in the blind hole inner wall surface of body one end, and copper sheet layer and respective inner walls are close to the fusion formula of connecting as one and are not had the solder structure.
The utility model one fusion on all-in-one-piece aluminum body is connected with the copper sheet layer, connects reliably, can not come off, and the bulk strength height of 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 upward view of Fig. 1.
Embodiment: as shown in the figure, the two ends of the body 1 of aluminum are equipped with blind hole 3, are provided with copper sheet layer 2 in blind hole 3 inner wall surface of body 1 one ends, and copper sheet layer 2 and respective inner walls are close to the fusion formula of connecting as one and are not had the solder structure.According to actual requirement, body 1 is provided with an end external diameter of copper sheet layer 2 can be less than the other end, and using in the connection of some power equipments like this can be more convenient.
During use, the blind hole 3 of two ends is connected with corresponding electrical power wiring end respectively, can conducts electricity transmission.Because the 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.
