Abstract
The utility model relates to an aluminum-based hot-rolled copper-clad transition equipment wire clamp and aims to provide an aluminum-based hot-rolling copper-clad transition equipment wire clamp which has the characteristics of good conductivity, less copper consumption and high technical content. The aluminum-based hot-rolled copper-clad transition equipment wire clamp comprises a wire clamp body, a plurality of pressing plates are fixed on the wire clamp body through bolts, and a standard spring washer is arranged between each pressing plate and the corresponding bolt. The aluminum-based hot-rolled copper-clad transition equipment wire clamp is characterized in that a copper layer is hot-rolled on the surface of an aluminum substrate of the wire clamp body, the copper layer is 0.1-4mm thick, the aluminum substrate is 1-20mm thick, and the copper layer is hot-rolled on a part of one side of the aluminum substrate or the copper layer is hot-rolled on a part of the two sides of the aluminum substrate or the copper layer is hot-rolled on the whole two sides of the aluminum substrate.
Description
Technical field
The utility model relates to the device clamp of commonly using in a kind of electric armour clamp, especially relates to the multiple copper transition equipment cable clamp of a kind of aluminium base hot rolling.
Background technology
, there is industry-by-industry, and be widely used in the demand that copper-aluminium transition connects.Electric armour clamp wire clamp of copper-aluminum apparatus plays one end and connects wire, the electric equipments such as other end subplate plate connection transformer, circuit breaker, isolating switch, and that on market, uses take friction welding (FW), flash welding, soldering, explosive welding (EW) as main.
Friction welding (FW), flash welding exist copper to consume excessive shortcoming, are the consumptions that covers several times of copper sheet welding.
The temperature capacity of soldered fitting is poor, temperature influence large, strength of joint is lower, during soldering the requirement of removing surface and weldment assembly quality higher.
Explosive welding (EW) annealing is difficult, and the rate that manufactures a finished product is low.Material source is difficult, open work in the wild mostly, mechanization intensity is low, working condition is poor, also climate condition restriction, explosion time produce noise and blast influential to environment.
As can be seen here, exist copper aluminium sales volume large in power industry, manufacturing cost is high, and industrialization degree is low, and complex process, the poor thermal climate that is subject to of working condition affect large shortcoming.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of aluminium base hot rolling multiple copper transition equipment cable clamp.
Concrete scheme is as follows:
The multiple copper transition equipment cable clamp of hot rolling, comprises wire clamp main body, has been bolted some pressing plates in wire clamp main body, is separated with reference rounds packing ring between pressing plate and nut, it is characterized in that: the aluminium base surface hot-rolled copper layer of described wire clamp main body.
Preferably, the local hot-rolled copper layer of described aluminium base one side.
Preferably, the two-sided local hot-rolled copper layer of described aluminium base.
Preferably, the two-sided whole hot-rolled copper layers of described aluminium base.
Preferably, described copper layer thickness is 0.1mm-4mm.
Preferably, described aluminium base thickness is 1mm-20mm.
Beneficial effect:
The multiple copper transition equipment cable clamp of aluminium base hot rolling of the present utility model has made up traditional backward technology.Adopt new material, have conduct electricity very well, copper material consumption is few, with high content of technology.
Electric conductivity is good obtains best electric conductivity, and resistivity < 0.019, and conductance is the more than 95% of fine copper, is better than soldering; Produce and all indoor, carry out, by the multiple copper hot rolling in convergence liquid aluminium surface, formed, productivity ratio is high.Product continuous 20 hours copper aluminium at 400 ℃ of temperature of high temperature is not separated, and good stability is higher than traditional handicrafts such as explosive welding (EW)s.

Wherein: 1-wire clamp main body, 2-pressing plate, 3-reference rounds packing ring, 4-aluminium base, 5-copper layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The multiple copper transition equipment cable clamp of a kind of aluminium base hot rolling, comprise wire clamp main body 1, some pressing plates 2 in wire clamp main body 1, have been bolted, between pressing plate 2 and nut, be separated with reference rounds packing ring 3, the surperficial hot-rolled copper layer 5 of aluminium base 4 of described wire clamp main body 1, described copper layer 5 thickness are 0.1mm-4mm, and described aluminium base 4 thickness are 1mm-20mm.
As Fig. 1: the local hot-rolled copper layers 5 of aluminium base 4 one sides.
As Fig. 2: the two-sided local hot-rolled copper layer 5 of aluminium base 4.
As Fig. 3: the two-sided whole hot-rolled copper layers 5 of aluminium base 4.
Finally, it is also to be noted that, what more than enumerate is only specific embodiment of the utility model, and obviously, the utility model is not limited to above examples of implementation, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should think protection range of the present utility model.
