The parallel groove clamp is characterized in that a thin copper sheet is arranged on the surface of one circular wiring groove, and the clamp body upper and bottom covers are prepared by aluminum material. According to the utility model, hot rolling is employed, so that a combination surface is high in intensity, peel strength of the aluminum-copper combination surface can reach 12N/mm, aluminum and copper are not layered during bending, consumed copper material is less, the size and use of the parallel groove clamp satisfy national standard, and material technology of the same is better than that of traditional materials.
Description
Technical field
The utility model relates to electric power copper-aluminium transition parallel groove clamp technical field, is specifically related to the multiple copper transition parallel groove clamp of a kind of aluminium base hot rolling.
Background technology
, there is industry-by-industry in the demand that copper-aluminium transition connects, and is widely used.The electric armour clamp cuprum aluminum wire clamp plays copper conductor, aluminium stranded conductor transition electric equipment, and that on market, uses take friction welding (FW), flash welding, soldering as main.
Friction welding (FW), flash welding parallel groove clamp: wire clip body is welded with half copper and half aluminium.Reach the purpose of copper-aluminium transition.Its shortcoming: copper consumes excessive, is the consumption that covers tens times of copper sheet welding.
The soldering parallel groove clamp: wire clip body be take and aluminium basely as main, utilized soldering that copper sheet is welded, and reaches the copper-aluminium transition purpose.Its shortcoming: the temperature capacity of soldered fitting is poor, temperature influence is large, strength of joint is lower, during soldering the requirement of removing surface and weldment assembly quality higher and can cause the power transmission and transformation line failure rate high.
As can be seen here, in power industry, copper aluminium sales volume is large, and manufacturing cost is high, and industrialization degree is low, the shortcoming of complex process.

The utility model content
Technical problem to be solved in the utility model be to provide a kind of have conduct electricity very well, copper material consumption is few, the multiple copper transition parallel groove clamp of the aluminium base hot rolling that adhesiveness is good.
Technical problem to be solved in the utility model realizes by the following technical solutions:
The multiple copper transition parallel groove clamp of a kind of aluminium base hot rolling, comprise binding clip main body upper cover and binding clip main body bottom, described binding clip main body upper cover and binding clip main body bottom link together by bolt and nut, described binding clip main body upper cover and binding clip main body bottom both sides all are arranged with after semicircle connecting groove on semicircle connecting groove described binding clip main body upper cover and binding clip main body bottom mutually combines the connecting groove that can form two circles, it is characterized in that: the surface of a connecting groove is provided with one deck scale copper therein, described binding clip main body upper cover and binding clip main body bottom are made by aluminum.
Be provided with a spring pad and a plain cushion between described nut and binding clip main body upper cover.
Described nut is through the centre position of binding clip main body upper cover and binding clip main body bottom.
Described scale copper is connected on connecting groove by the mode of hot rolling.
The whole rectangular structure of described binding clip main body upper cover and binding clip main body bottom.
Bottom, described binding clip main body bottom centre position is provided with nut groove.
Described scale copper is arranged at binding clip main body upper cover with on two relative connecting groove surfaces on binding clip main body bottom.
Described scale copper is identical with the shape of connecting groove.
The beneficial effects of the utility model are:
1, interface bond strength is high, adopt the multiple copper (aluminium reaches smelting temperature in the compound hot rolling of copper) of aluminium base hot rolling, form the certain thickness binder course, thereby higher than solid phase combination interface bond strength, guarantee to be sheared, punching, copper when crooked, aluminium be not stratified, the stress produced in the time of standing to expand with heat and contract with cold in a big way.
2, interface can not produce couple corrosion, manufacture and good in conjunction with bonding effect in anaerobic, pollution-free, complete clean environment in the whole course of processing.
3, good electric conductivity, machine sunykatuib analysis and testing authentication as calculated, due to the impact of skin effect, the height that resistivity calculates than copper, aluminium parallel connection through actual measurement.The volume ratio of copper 20% the time, can obtain best electric conductivity, resistivity<0.019, and conductance is more than 95% of fine copper, is the optimal selection that replaces pure cu conductor.
4, good heat conductivility, the copper-aluminum composite board band, through the cold rolling Strip that is processed into different-thickness, because anaerobic metallurgy is compound, without the heat transfer contact thermal resistance, have copper, aluminum metal good heat transfer capacity, can in copper, the aluminum metal scope of application, bear hot conditions.
5, good installation capability, its bending property are better than the same conductor of same equal-specification, and because interface bond strength is high, boring, crooked, while stretching, copper aluminium can layering.
6, cost is low, with copper aluminium friction welding (FW) parallel groove clamp, is as the criterion, equal sectional area, and equal length, its price is covered half of copper less than hot rolling.
