Abstract
The utility model relates to a copper-aluminium wiring terminal, comprising an aluminium body; one end of the aluminium body is pipe-shaped, and the other end of the aluminium body is flat; the flat end is also provided with a connecting through hole; the flat end of the aluminium body is formed by flattening a pipe shape; and the whole inner wall of the aluminium body, including the inside of the flat end, is respectively coated with a copper piece layer. The flat end of the copper-aluminium wiring terminal is formed by flattening the pipe shape, when in production, the inner wall or the outer wall of the aluminium pipe is combined with the copper piece layer firstly by solid phase, and then is cut off, the end parts are flattened, the copper-aluminium material are firmly combined, the permanent interatomic combination can be achieved, and the whole strength is greatly improved; the copper-aluminium wiring terminal is not fractured and does not fall, also has certain plasticity, and is beneficial to machining. In addition, the covering surface of the copper piece is wide, the conducting performance is very excellent, the used copper is less, the cost is reduced, and the weight is light.
Description
Technical field: the utility model relates to the copper-aluminium transition binding post that uses in a kind of Allocation transformer circuit.
Background technology: in the Allocation transformer circuit, often need to use copper al wiring terminal to connect different cable, electric equipment with transition.General copper al wiring terminal all is to adopt modes such as soldering, flash welding or friction welding (FW) to link the copper sheet layer at the flat end outer surface of aluminum body, but the general bonded area of these frame modes is less, commissure resistance is big, conductivity is undesirable, corrosion-vulnerable influence in the use, weld ruptures easily, and the copper consumption in the production is also bigger, and cost is improved.And in weld meeting flow harden, then weld strength is low to adopt soldering in conjunction with copper sheet for employing flash welding or friction welding (FW), and high temperature comes off easily.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of and conducts electricity very well, the copper al wiring terminal of reliable operation.
The utility model comprises the aluminum body of an end tubulose, other end flat, flat end also is provided with connecting through hole, the flat end of this aluminum body flattens moulding by tubulose and constitutes, and the whole inwall of aluminum body, comprises that flat end inside all covers and be combined with the copper sheet layer.
In fact, the utility model can cover the outer wall that is combined in aluminum body with the copper sheet layer, forms the transition binding post of copper cover aluminum form.
Flat end of the present utility model flattens moulding by tubulose, can be earlier during production after aluminum pipe inwall or outer wall solid phase are in conjunction with the copper sheet layer, cut off again and the end flattening, the combination of copper aluminium material material is firm, can reach combination between nonvolatil atom, bulk strength improves greatly, can breaking releasing, also certain plasticity can be arranged, help machine work.And the broad covered area of copper sheet, electric conductivity is very excellent, and the copper material of use is few, and cost reduces, and is in light weight.
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 1;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is the main structure schematic diagram of embodiment 2;
Fig. 5 is the left view of Fig. 4.
Embodiment: embodiment 1: arrive shown in Figure 3 as Fig. 1, one end tubulose of aluminum body 1, other end flat, flat end also is provided with connecting through hole 3, the flat end of this aluminum body 1 flattens moulding by tubulose and constitutes, and the whole inwall of aluminum body 1, comprises that flat end inside all covers and be combined with copper sheet layer 2.
During actual production, present embodiment is earlier the aluminum pipe inwall to be adopted mode solid phase such as hot extrusion in conjunction with last copper sheet, makes through operations such as cut-out, flattening, punchings again, obtains the transition binding post of aluminium copper-clad.
Embodiment 2: basic as embodiment 1 as shown in Figure 4 and Figure 5, and an end tubulose of aluminum body 1, other end flat, flat end also is provided with connecting through hole 3, and copper sheet layer 2 is to cover the outer wall that is combined in aluminum body 1.Present embodiment then be with aluminum pipe outer wall elder generation solid phase in conjunction with last copper sheet, make the transition binding post of copper cover aluminum again.
Claims (2)
