Abstract
The utility model relates to a bolt type copper and aluminum transitional terminal connector which comprises a principal line plate and a tension disc fixedly arranged on the principal line plate through a bolt, wherein a slot is formed between the principal line plate and the tension disc; and the principal line plate is provided with an aluminum substrate and a copper plate. The aluminum substrate and the copper plate are fixed by means of welding to form a weld line. The weld line is coated by an insulating layer, so that the aluminum substrate and the copper plate are more reliably and stably connected and not easy to fall.
Description
Technical field
The utility model relates to a kind of contact gold utensil, relates in particular to a kind of bolt type copper aluminium transition equipment cable clamp.
Background technology
In the prior art, the main line plate of bolt type copper aluminium transition equipment cable clamp by the welding mode so that aluminium base and copper coin be fixed together, therefore, in actual the use, the anti-fracture performance of described copper-aluminium transition equipment cable clamp is particularly crucial, because the coefficient of expansion of copper and aluminium, conductivity, the physical properties such as density are different, therefore the strength ratio on the composition surface of copper aluminium is fragile, especially at wind and rain, thunder and lightning, breaking under the erosion of the environmental factors such as moisture, cooperate under the long-time running of large electric current, the high temperature heating causes the product fracture easily, cause various power grid accidents, even large area blackout, this phenomenon is one and is easy to unheeded major safety risks, also therefore normal engineer operation is produced greatly impact.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of simple in structure, reliable and stable bolt type copper aluminium transition equipment cable clamp is provided.
For achieving the above object, the utility model adopts a kind of bolt type copper aluminium transition equipment cable clamp, comprise main line plate and the tension disc that is bolted on the main line plate, and form trunking between described main line plate and the tension disc, described main line plate has aluminium base and copper coin, fix and form weld seam by the mode of welding between this aluminium base and the copper coin, be coated with insulating barrier on the weld seam of described main line plate.
Concrete, described insulating barrier is preferably the waterproof gauze.
By the technique scheme improvements over the prior art, owing to be coated with a layer insulating in the weld seam periphery, so that position while welding is more firm because being subject to pressing of insulating barrier, in the long-term use of wire clamp, even weld seam produces the phenomenon of splitting, also can delay because of the support effect of the copper coin around the insulating barrier butt welded seam of periphery parcel and aluminium base the continuation fracture of weld seam, and then the useful life of prolongation wire clamp, especially after insulating barrier being preferably the waterproof gauze, can prevent especially the infiltration of sealing and urge erosion, further guarantee the reliability of wire clamp.
