A kind of copper aluminium cable Welding Structure
Technical field
The utility model relates to a kind of wire connection structure, specifically is a kind of copper aluminium cable Welding Structure.
Background technology
At present, along with rising steadily of copper cash price, many electric pumps enterprise all adopts aluminum steel to replace copper cash, to save precious metal, to reduce production costs, but after changing electromagnetic wire into aluminum steel, the welding procedure difficulty between its inner aluminum steel and aluminum steel, aluminum steel and the copper cash also increases thereupon.At present to copper aluminium to being connected to several different methods, conventional method is to adopt welding manner that copper aluminium Butt Section is connected, (1) owing to being difficult to guarantee weldquality, therefore the poor shortcoming of weld strength can occur in the practice of construction process.(2) existing tin silk welds, the shortcoming that the method exists is too fast, the poor adhesive force of scolding tin Heated Flow when welding, cause growth weld time, scolding tin loss to increase, easily cause rosin joint, the price of well-known copper, aluminium scolding tin is very expensive again, so conventional method is unfavorable for reducing manufacturing cost.Therefore need to be improved this.
The utility model content
The purpose of this utility model is to overcome the deficiency that existing mode exists, and provides copper aluminium cable Welding Structure by improving at this, has simple and practical, the material-saving that saves time, reduces the advantage such as cost.
The utility model is to realize like this, construct a kind of copper aluminium cable Welding Structure, it is characterized in that: connection head end A corresponding to copper conductor that needs connect is wrapped on the aluminum conductor connection end B of aluminum conductor docking, and the link place that copper conductor is corresponding with aluminum conductor covers by weld layer.
According to a kind of copper aluminium cable Welding Structure described in the utility model, it is characterized in that: described copper conductor is divided into 3 strands or 4 strands and is wrapped on the aluminum conductor.
The beneficial effects of the utility model are: the utility model is by a kind of copper aluminium cable Welding Structure provide is provided, and has simple and practical, the material-saving that saves time, reduces the advantage such as cost; Can solve existing weld time of long, the problem such as loss is large, saved weld time and raw material, and welding section be very smooth, even, avoid behind the aluminum steel oxidation of rosin joint place and the dipping lacquer problems such as service interruption, welding quality is high.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 101, copper conductor, 101a, connect head end A, 102, aluminum conductor, 102a, connection end B, 103, weld layer.
Embodiment
Be described in detail below in conjunction with 1 pair of the utility model of accompanying drawing:
The purpose of this utility model is to overcome the deficiency that existing mode exists, and provides a kind of copper aluminium cable Welding Structure by improving at this, has simple and practical, the material-saving that saves time, reduces the advantage such as cost.As shown in Figure 1: a kind of copper aluminium cable Welding Structure described in the utility model, the connection head end A101a of copper conductor 101 correspondences that need to connect is wrapped on the aluminum conductor connection end B102a of aluminum conductor 102 docking, and link place corresponding to copper conductor 101 and aluminum conductor 102 is by weld layer 103 coverings.Wherein said copper conductor 101 is divided into 3 strands or 4 strands and is wrapped on the aluminum conductor 102.Before welding, copper cable is stripped out copper cash, copper cash is divided into 3 strands or 4 strands is wrapped on the aluminum steel, weld, wherein the fusion temperature of copper is than the height of aluminium, (copper is 1083 ℃, and aluminium is 660.4 ℃).Copper aluminium cable Welding Structure described in the utility model can fix welding, guarantee welding quality, can solve existing weld time of long, the problem such as loss is large.
