Abstract
The utility model relates to a copper-aluminum composite bar with grooves. The copper-aluminum composite bar includes a composite bar body (1). The composite bar body (1) comprises a copper pipe (2) and an aluminum layer (3); the aluminum layer (3) is filled the copper pipe (2); and the outer surface of the composite bar body (1) is provided with the grooves (2). According to the copper-aluminum composite bar with the grooves of the utility model, aluminum material is replaced by copper material, thereby reducing production cost; and through setting the grooves, the copper-aluminum composite bar is of convenience in placement, and materials can be saved.
Description
Technical field
The utility model relates to a kind of reeded copper aluminium composite bar of being with.
Background technology
Copper bar is a kind of conducting heavy current product, uses very extensively, is applicable to the electro-engineerings such as high and low voltage electrical equipment, switch contact, controller switching equipment, bus duct, also is widely used in the super-large current electrolysis for production engineerings such as metal smelt, electrification plating, chemical industry caustic soda.Traditional copper bar all is made of copper, and production cost is just very high like this, and the copper bar outer surface does not arrange groove in addition, so be not easy to the placement of copper bar, has wasted material yet.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of reeded copper aluminium of being with of material composite bar of being convenient to place and save is provided.
The purpose of this utility model is achieved in that
A kind of copper aluminium composite bar comprises the composite bar body, and described composite bar body comprises copper pipe and aluminium lamination, is filled with aluminium lamination in the described copper pipe, and the outer surface of described composite bar body is provided with groove.
The utility model copper aluminium composite bar is stated the copper pipe cross section and is the round rectangle shape.
The utility model copper aluminium composite bar, described composite bar body is L-type.
Compared with prior art, the beneficial effects of the utility model are:
The reeded copper aluminium of the utility model band composite bar aluminium instead of copper has reduced production cost, and by groove is set, also is convenient to place, and has also saved material.
Description of drawings
Fig. 1 is the structural representation of the reeded copper aluminium of the utility model band composite bar.
Fig. 2 is the sectional view of Fig. 1.
Wherein:
Composite bar body 1
Groove 2
Aluminium lamination 4.
Embodiment
Referring to Fig. 1 and Fig. 2, the reeded copper aluminium of the utility model band composite bar comprises composite bar body 1, and described composite bar body 1 comprises copper pipe 2 and aluminium lamination 3, and described copper pipe 2 cross sections are the round rectangle shape, are filled with aluminium lamination 3 in the described copper pipe 2.
Described composite bar body 1 is L-type.
The outer surface of described composite bar body 1 is provided with groove 2.
At copper pipe 2 interior filling aluminium laminations 3, because the price of aluminium is lower than copper, thus greatly reduce production cost, and not decline of electric conductivity, can normally use; In addition, after the outer surface of composite bar body 1 is provided with groove 2, placement space can be saved, also material can be saved.
Claims (3)
1. be with reeded copper aluminium composite bar for one kind, comprise composite bar body (1), it is characterized in that: described composite bar body (1) comprises copper pipe (2) and aluminium lamination (3), is filled with aluminium lamination (3) in the described copper pipe (2), and the outer surface of described composite bar body (1) is provided with groove (2).
2. a kind of copper aluminium composite bar according to claim 1, it is characterized in that: described copper pipe (2) cross section is the round rectangle shape.
3. a kind of copper aluminium composite bar according to claim 1, it is characterized in that: described composite bar body (1) is L-type.
