Description
Technical field
The utility model relates to increase-volume soft state aluminium core wire and the copper core cable connector field of electric equipment, is specifically related to a kind of corrosion resistance between copper core, aluminum core line cable and the strong straight-through stifled oil type increase-volume soft state aluminum alloy copper aluminium connecting tubes part of creep resistance.
Background technology
Tube connector is a kind of accessory product be connected with the transition of aluminum core line cable for realizing copper core cable, the industrial category being divided into connector, along with industrial automatization is more and more higher and Industry Control requires more and more stricter, accurate, and under the overall background of national two-channel filter banks, the consumption of tube connector goes up gradually.Along with the development of electron trade, the scope of application of tube connector gets more and more, and kind also gets more and more.But, generate electricity, power, hold accident-prone position most with electric transmission channel at the contact place that increase-volume cable aluminium core is connected with copper core cable connection line, common L2 aluminium main cause is: with the passage of time, wind and rain Exposure to Sunlight when its corrosion-resistant, creep resistance is not good, when be corroded and creep very easily come in contact bad, thus when causing load current heating and there is breaking current accident.
Utility model content
In order to solve the defect that above-mentioned technology exists, the utility model provides a kind of corrosion resistance and strong the leading directly to of creep resistance to block up oil type soft state alloyed copper aluminium connecting tubes.
The utility model realizes the technical scheme that above-mentioned technique effect adopts:
A kind of straight-through stifled oil type increase-volume soft state aluminum alloy copper aluminium connecting tubes part, comprise and be positioned at the first wire barrel on same circuit and the second wire barrel, described first wire barrel is the first wire barrel of soft state increase-volume aluminum alloy material, described second wire barrel is the second wire barrel of oxygen-free copper material, described first wire barrel and described second wire barrel adopt friction-welding technique to fix, there is the connecting portion of reducing shape, be provided with increase-volume aluminum core line cable connecting groove in described first wire barrel, in described second wire barrel, be provided with copper core cable copper core cable connecting groove.
The straight-through stifled oil type increase-volume soft state aluminum alloy copper fasten aluminium of above-mentioned one, the caliber of described first wire barrel is greater than the caliber of described second wire barrel, the bottom of described increase-volume aluminum core line cable connecting groove and described copper core cable connecting groove is the taper surface of indent or the circular face of indent, is convenient to the saving of the cable energy.
The beneficial effects of the utility model are: the second wire barrel friction welding of the first wire barrel of soft state aluminium alloy and oxygen-free copper material is formed the straight-through Cu-Al connecting pipe part blocking up the soft state of oil type increase-volume by the utility model, the corrosion resistance of whole tube connector and creep resistance is made to obtain remarkable increase, compare existing tube connector, its creep-resistant property improves 300%, has the feature of light weight, good conductivity simultaneously.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
In figure: 1-first wire barrel, 2-second wire barrel, 3-connecting portion, 4-increase-volume aluminum core line cable connecting groove, 5-copper core cable connecting groove.
Embodiment
For making to do further to understand to the utility model, referring to Figure of description and specific embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of straight-through stifled oil type increase-volume soft state aluminium alloy connecting tube, comprise the first wire barrel 1 and the second wire barrel 2 be positioned on same circuit, this first wire barrel 1 is the first wire barrel of soft state increase-volume aluminum alloy material, and this second wire barrel 2 is the second wire barrel of oxygen-free copper material.First wire barrel 1 and the second wire barrel 2 adopt friction-welding technique to fix, there is the connecting portion 3 of reducing shape between the two, friction welding is namely under rotational pressure effect, by the copper aluminium material material fusing point friction at interface to be welded, interface and neighbouring temperature thereof are raised, material section reaches hot melt state, produce fusing point stream along with material to become, realize welding by the molecular diffusion at interface and recrystallization.Compare traditional melting welding or soldering, friction-welding technique has the high feature of quality of weld joint, and it can reach weld strength and be equal to intensity with basis material, and welding efficiency is high, steady quality, consistent performance are good, can realize welding dissimilar materials.One-body molded by the whole tube connector of friction-welding technique, surperficial round and smooth impulse-free robustness.Be provided with in first wire barrel 1 in increase-volume aluminum core line cable connecting groove 4, second wire barrel 2 and be provided with copper core cable connecting groove 5.The caliber of the first wire barrel 1 is greater than the caliber of the second wire barrel 2, and the bore of increase-volume aluminum core line cable connecting groove 4 is slightly larger than the bore of copper core cable connecting groove 5.The bottom of increase-volume copper core cable connecting groove 4 and copper core cable connecting groove 5 is taper surface or the indent rounded bottom surface of indent.
First wire barrel 1 of soft state increase-volume aluminium alloy and the friction welding of the second wire barrel 2 of oxygen-free copper material are formed the straight-through Cu-Al connecting pipe part blocking up the soft state of oil type increase-volume of straight pipe type by the utility model, the corrosion resistance of whole tube connector and creep resistance is made to obtain remarkable increase, compare existing tube connector, its creep-resistant property improves 300%, has the feature of light weight, good conductivity simultaneously.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications; these changes and improvements all fall in claimed scope of the present utility model, and the protection range that the utility model requires defined by appending claims and increase-volume cable soft state aluminium alloy accessory equivalent thereof.
