Abstract
一种铜铝过渡接线端子，包括后部的铝制管体与前部的铝制接线板，在后部的铝制管体上有一盲孔，铝制管体与铝制接线板为一体式结构，在前部的铝制接线板的上下面均爆焊有铜片层。由于本实用新型铜板与铝板间采用爆炸焊接，复合强度高，接触电阻小，导电性好，铝为一体式结构，整体强度高，不会断裂。且整个端子只消耗少量的铜片，节约了铜材，降低了生产成本。而且接线板上下均焊有铜片，可满足不同的连接方式。
A copper-aluminum transition terminal, comprising an aluminum tube body at the rear and an aluminum terminal board at the front, a blind hole is formed on the aluminum tube body at the rear, and the aluminum tube body and the aluminum terminal board are integrated structure, copper sheet layers are blast-welded on the upper and lower sides of the aluminum wiring board at the front. Because the utility model adopts explosive welding between the copper plate and the aluminum plate, the composite strength is high, the contact resistance is small, the conductivity is good, and the aluminum is an integrated structure, the overall strength is high, and it will not break. Moreover, the entire terminal only consumes a small amount of copper sheets, which saves copper materials and reduces production costs. Moreover, copper sheets are welded on the top and bottom of the wiring board, which can meet different connection methods.
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).
