Abstract
The utility model relates to a wire clamp for copper-aluminum filtering equipment, and the wire clamp mainly comprises a circular pipe part and a rectangular part. The circular pipe part and the rectangular part are connected with each other, and the rectangular part is coated with a copper layer. The copper layer is coated on an upper end face, a lower end face, a left end face and a right end face, and a side, far from the circular pipe part, of the rectangular part. The wire clamp is advantageous in that an original copper layer is coated on the outer surface of an aluminum layer, thereby reducing the usage amount of copper, and saving cost.
Description
Technical field
The utility model relates to a kind of copper aluminium filter plant wire clamp, a kind of device that can be cost-saving specifically.
Background technology
Device clamp rolls off the production line and is connected with the outlet terminal of electric equipment (as transformer, circuit breaker, instrument transformer, isolating switch, wall bushing etc.) for bus leading.The outlet terminal of now conventional electric equipment has copper and aluminium matter two classes, and lead-out wire mostly is aluminium stranded conductor or steel reinforced aluminium conductor, therefore device clamp is divided into again aluminum equipment wire clamp and two series of copper-aluminium transition equipment cable clamp.Be divided into screw bolt-type device clamp and compression-type device clamp according to the installation and application of device clamp.
Copper aluminium connects can produce electrochemical reaction, increases contact resistance, burns joint, can avoid this problem with copper-aluminium transition equipment cable clamp.At present, the copper-aluminium transition equipment cable clamp using in existing market, its common structure is to adopt copper layer and aluminium lamination to be welded, and adopts such mechanism, and in the time producing, the amount of the copper that need to use will be larger, and corresponding cost is higher.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of cost-saving copper aluminium filter plant wire clamp.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of copper aluminium filter plant wire clamp, and its innovative point is: mainly comprise pipe portion and rectangular portion;
Described pipe portion is connected with rectangular portion, is coated with layer of copper layer in rectangular portion, and described copper layer is plated in respectively four of the upper and lower, left and right end face of rectangular portion and the rectangular portion side away from pipe portion.
The utility model has the advantage of: the structure of original copper layer and aluminium lamination splicing is changed to copper is plated on the outer surface of aluminium lamination and forms layer of copper layer, reduced like this use of copper, saved cost.
