Abstract
The utility model relates to a copper-aluminum special-shaped parallel-groove wire clamp. The copper-aluminum special-shaped parallel-groove wire clamp includes a bolt assembly, an aluminum laminated plate, an upper cover plate and a bottom plate. The bolt assembly penetrates the aluminum laminated plate, the upper cover and the bottom plate successively so as to enable fixed installation; one side of corresponding positions of the upper cover plate and the bottom plate is provided with oppositely-arranged arc-shaped wire grooves; and the other side of the corresponding positions of the upper cover plate and the bottom plate is respectively provided with an inverted trapezoid-shaped groove and a regular trapezoid-shaped groove which are oppositely arranged; and copper plates are inlaid in the inverted trapezoid-shaped groove and the regular trapezoid-shaped groove. Compared with a method in which cooper plates are welded on an aluminum-made body in the prior art, the copper plates are respectively inlaid in the inverted trapezoid-shaped groove and the regular trapezoid-shaped groove according to the copper-aluminum special-shaped parallel-groove wire clamp of the utility model, such that contact areas of the grooves and the cooper plates are effectively increased, and two side edges of the trapezoid-shaped grooves can effectively fix the copper plates so as to avoid the dropping of the copper plates. In conclusion, the inverted trapezoid-shaped groove and the regular trapezoid-shaped groove on the upper cover plate and the bottom plate are adopted to inlay the copper plates, and therefore, the copper-aluminum special-shaped parallel-groove wire clamp is advantageous in stability, reliability and a long service life.
Description
Technical field
The utility model relates to a kind of jockey that is applied to high and low pressure electrical lead installing area, is specifically related to a kind of copper aluminium Special-shaped parrel-slot cable clamp.
Background technology
As everyone knows, in the connection of electrical lead, often to use the ability that the mode that aluminum steel is transitioned into copper cash continues the wire conduct power, therefore, copper aluminium Special-shaped parrel-slot cable clamp arises at the historic moment, copper aluminium Special-shaped parrel-slot cable clamp of the prior art is offered the arc wire casing by two corresponding side positions on upper cover plate and base plate, and the mode that the copper sheet layer is set on the arc wire casing of a side therein realizes that aluminum steel is to the connected mode of copper cash transition, yet the existing copper aluminium of this kind Special-shaped parrel-slot cable clamp has following defectives: 1, owing to have the gap between the upper cover plate of all side of the copper sheet layer on the arc wire casing and aluminum and the base plate, and copper aluminium Special-shaped parrel-slot cable clamp is generally used out of doors, therefore, outdoor rainwater, humidity, thunder and lightning, the environmental factors such as dust storm as easy as rolling off a log by this gap so that the oxidation of copper sheet layer come off; 2, copper sheet layer of the prior art all is to be fixed on the arc wire casing by brazing mode, and the Welding technology difficulty is large, solder wetting is also poor, cause the contact-making surface apodization rate of copper sheet layer and aluminum body high, bond strength is low, so that the some resistance that copper-aluminium transition engages is large, so that the loss of electric power transfer strengthens.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, provides a kind of and can effectively reduce copper sheet pull-up fall risk and copper aluminium Special-shaped parrel-slot cable clamp reliable and stable, high life.
For achieving the above object, the utility model adopts a kind of copper aluminium Special-shaped parrel-slot cable clamp, comprise bolt assembly, aluminium pressing plate, upper cover plate and base plate, wherein said bolt assembly passes successively aluminium pressing plate, upper cover plate and base plate and forms fixed installation, a wherein side of described upper cover plate and base plate opposite position offers respectively arc wire casing staggered relatively, the opposite side of described upper cover plate and base plate opposite position offers respectively inverted trapezoidal groove staggered relatively and trapezoid groove, is inlaid with copper coin in described inverted trapezoidal groove and the trapezoid groove.
By the technique scheme improvements over the prior art, after copper coin is inlaid into respectively inverted trapezoidal groove and trapezoid groove, for the copper coin that is welded in the prior art on the aluminum body, effectively increased the contact area of groove and copper coin, and the dual-side of trapezoidal groove can be effectively fixing copper coin and then prevent that copper coin from coming off, in sum, after adopting respectively inverted trapezoidal groove and trapezoid recess-mounted copper coin on upper cover plate and the base plate, reached reliable and stable, the effect of long service life.
Preferably, for preventing the environmental factors such as rainwater, moisture, temperature to the oxidation of copper coin and aluminum essence joint, the gap location between described copper coin and inverted trapezoidal groove and trapezoid groove is provided with epoxy glue layer.
Preferably, be provided with fixed part to downward-extension on the bottom face of described base plate, offer the installing hole that has internal thread and be fitted to bolt on this fixed part, by directly after base plate arranges the internal thread installing hole, can directly fixedly mount by this installing hole with bolt, need to set up in the base plate bottom needs that nut is fixed and saved in the prior art, strong reduction production cost, improved production efficiency.
