Abstract
The utility model discloses an aluminum-base copper-aluminum connecting tube which is made of aluminum. The external shape of the aluminum-base copper-aluminum connecting tube is cylindrical. Both ends of the connecting tube are provided with inserting holes which are suitable for being inserted with electric wires (cables) with aluminum cores and copper cores. A layer of alloy used for the transition between the copper and the aluminum is inlaid in the inserting hole of the electric wire (cable) with the copper core. The connecting tube of the utility model has the advantages of good transferring performance for electric power, high reliability, simple working procedure, low cost and good performance for resisting pulling and bend.
Description
The utility model belongs to circuit connecting circuit element class, a kind of specifically wire barrel that is used for aluminium core, copper core electric wire (cable) transition connection.
Aluminum current core electric wire (cable) with copper core electric wire (cable) transition to be connected all be to adopt traditional copper al wiring pipe.The end that the end that this wire barrel (see figure 2) has copper core electric wire (cable) patchhole 4 adopts copper material 6, have aluminium core electric wire (cable) patchhole 1 adopts aluminium 2, and copper material, aluminium adopt argon arc welding, and the low temperature friction welding is an one, between weld seam 5 is arranged.This wire barrel needs a large amount of technological equipment and means, processed complex, cost height in process of production for ensuring the quality of products.Weld seam is arranged on the wire barrel, influenced its tension, bending strength.Stock utilization is low, and particularly the copper material utilance is quite low.
The purpose of this utility model provides and does not a kind ofly need to use copper material just can carry out copper, aluminium core electric wire (cable) transition to connect, and can satisfy the special-purpose wire barrel of the every specification requirement of copper-aluminium transition.
The purpose of this utility model realizes in the following manner, aluminium base copper al wiring pipe all adopts aluminium 2 to make, two ends have the patchhole 1 that inserts aluminium core electric wire (cable) respectively, the patchhole 4 of copper core electric wire (cable), and patchhole 4 is embedded with the alloy that one deck is used for transition between copper, aluminum metal.
With reference to the accompanying drawings the utility model structure and function are described:
Fig. 1 the utility model structural representation
Fig. 2 has the wire barrel structural representation now
With reference to Fig. 1, this wire barrel profile is cylindrical, the patchhole 1 of aluminium core electric wire (cable), and the diameter of the patchhole 4 of copper core electric wire (cable) should adapt to the aluminium core that is inserted, the diameter of copper core, and the degree of depth in hole is by the degree of depth decision that should insert.Steel core patchhole 4 inwalls are embedded with copper, aluminium transition alloy is the high purity alloys with low resistance, high resistance to corrosion.When this wire barrel uses, only need copper core, aluminium core are inserted in the patchhole 4,1, then adopt partial points crimping method or the crimping of whole confined pressure method, can realize that the transition of copper, aluminium electric wire (cable) connects.
The utility model has the advantage of:
1, owing to adopt the high purity alloys of a low resistance, high resistance to corrosion, as transition material, so its power delivery performance is good, resistance to corrosion is strong, reliability is high.
2, because this product all adopts aluminium, and processing technology is special, has avoided copper aluminium to add under hot conditions and has produced the brittle alloy layer man-hour, so its mechanical strength is good, bending resistance, tension indices all are higher than traditional product.
3, manufacturing procedure is simple, and processing cost is low.
4, use simply, and convenient and reliable.
Claims (3)
1, a kind of aluminium base copper al wiring pipe, two ends have the patchhole 1 that inserts aluminium core electric wire (cable), the patchhole 4 of copper core electric wire (cable) respectively, it is characterized in that wire barrel all adopts aluminium 2 to make, patchhole 4 is embedded with the alloy 3 that one deck is used for transition between copper, aluminum metal.
2, wire barrel according to claim 1 is characterized in that being used for the alloy 3 of transition between copper, aluminum metal for having the high purity alloys of low resistance, high resistance to corrosion.
3, wire barrel according to claim 1 is characterized in that the profile of wire barrel is cylindrical.
