Abstract
A copper-aluminum transition wire connecting terminal consists of an aluminum tube in the rear part and an aluminum patch panel in the front part. A dead hole is arranged on the aluminum tube in the rear part; the aluminum tube and the aluminum patch panel form a one-piece construction; the upper surface and the lower surface of the aluminum patch panel in the front part are respectively explosively welded with a copper sheet layer. As the copper plate and the aluminum plate of the utility model are explosively welded, the copper to aluminum adapter wire connecting terminal has the advantages of high combined strength, small constriction resistance, good electric conductivity and that the aluminum is a one-piece construction, which has high integrated intensity and can not fracture. Furthermore, the whole terminal only consumes a small amount of copper sheet, which saves copper material and reduces production cost. In addition, copper sheets are welded both on the upper part and the lower part of the patch panel, which can satisfy different connection types.
Description
Technical field
The utility model relates to a kind of binding post that adopts the electric power transfer connection usefulness of explosion weld process.
Background technology
Copper-aluminium transition equipment cable clamp is used for outdoor power distribution unit median generatrix downlead and is connected with electric equipment, directly is connected the generation couple corrosion to prevent copper with aluminium.Copper and aluminium are the conductor materials of consumption maximum in the present electric field, in power engineering, being electrically connected of two kinds of materials of copper aluminium inevitably occur.As everyone knows, being in the electrolyte, having the primary cell of two kinds of metals formation of various criterion current potential, is electrochemical most typical form.When especially both potential differences were greater than 0.75V, it is very active that couple corrosion becomes, if adopt mechanical pressure (as bolted) that two kinds of metals are directly contacted, will inevitably leave the slit on contact-making surface.When having electrolyte in the slit, primary cell inevitably forms.Simultaneously, the degradation speed of contact-making surface is further quickened in the corrosion that also can produce electrolysis of flowing of electric current.Therefore, all clear and definite regulation in all kinds of relevant technical standards and the standard: the conductor of different materials must not directly be connected.
Existing copper-aluminium transition binding post comprises the aluminum body at rear portion and the aluminum terminal block of front portion, on the aluminum body at rear portion a blind hole is arranged, and aluminum body and aluminum terminal block are integral structure, fore aluminum terminal block end face welding copper terminal block.The welding manner that is used for copper and aluminium has friction weldering, flash welding, soldering.Traditional friction weldering and flash welding are bigger to the use amount of copper material, and cost is higher.And solder side is less, and commissure resistance is bigger, produces stress because of non-uniform temperature between copper aluminium when welding, insecure, cause the device clamp embrittlement, crackle appears, occur burn into aeolian vibration etc. in addition in actual applications and easily cause the binding post fracture, serious meeting causes electric power accident.Soldering exists weld strength not high through regular meeting again, compound area shortcoming such as inadequately, easily come off.And existing copper-aluminium transition binding post, the copper consumption is big, the cost height.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model has been to provide a kind of copper-aluminium transition binding post that adopts explosion weld process, its intensity height, and good conductivity, cost is low.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of copper-aluminium transition binding post, the aluminum body and anterior aluminum terminal block that comprise the rear portion, on the aluminum body at rear portion, a blind hole is arranged, aluminum body and aluminum terminal block are integral structure, all quick-fried copper sheet layer that is welded with in the top and bottom of fore aluminum terminal block.
Since adopt explosive welding between the utility model copper coin and aluminium sheet, the combined strength bination height, contact resistance is little, good conductivity, and aluminium is integral structure, the bulk strength height can not rupture.And whole terminal only consumes a spot of copper sheet, has saved copper material, has reduced production cost.And terminal block all is welded with copper sheet up and down, can satisfy different connected modes.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of present embodiment.
Fig. 2 is the A-A cutaway view among Fig. 1.
Among the figure: 1, copper sheet layer, 2, the aluminum body, 3, blind hole, 4, the hole, 5, the aluminum terminal block.
Specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1 and Fig. 2, a kind of copper-aluminium transition binding post, the aluminum body 2 and anterior aluminum terminal block 5 that comprise the rear portion, one blind hole 3 is arranged on the aluminum body 2 at rear portion, aluminum body 2 is an integral structure with aluminum terminal block 5, all quick-fried copper sheet layer 1 that is welded with in the top and bottom of fore aluminum terminal block 5.
Referring to Fig. 1 and Fig. 2, be provided with hole 4 in the middle of the aluminum terminal block 5.
The top and bottom of fore aluminum terminal block 5 all are welded with copper sheet layer 1, are provided with hole 4 in the middle of the aluminum terminal block 5, to adapt to different connected modes.In use, the blind hole 3 at rear portion is connected with lead, anterior terminal block and accordingly the electrical power wiring end face fixedly connected, can conduct electricity.Because the front end terminal block surface all has copper sheet layer 1 up and down, connected mode is versatile and flexible.Middle aluminium is integral structure, the reliability height.
Claims (2)
1, a kind of copper-aluminium transition binding post, the aluminum body (2) and anterior aluminum terminal block (5) that comprise the rear portion, on the aluminum body (2) at rear portion, a blind hole (3) is arranged, aluminum body (2) is an integral structure with aluminum terminal block (5), it is characterized in that: all quick-fried copper sheet layer (1) that is welded with in the top and bottom of fore aluminum terminal block (5).
