Abstract
The utility model discloses a kind of copper-aluminum transition connecting terminal, employing copper-aluminum composite board is made, for the column single piece of internal layer aluminium, external sheath copper material, one end is the solid-section other end is hollow section, hollow section be cylindrical section for crimping outside line aluminum steel, the shape of solid-section is mated with house lead in air switch connected structure.Copper-aluminum composite board is through stamping-out blanking, drawing and forge shaping being made.The utility model adopts Copper-Aluminum compound sheet material through stamping-out blanking, two to three drawing and once forges shaping, and the omnidistance punch press that uses is processed, and stock utilization and production efficiency significantly improve, and scrappage is low, and processing cost is low.Be the splicing ear of the hollow other end solid construction in one end after shaping, its copper-aluminium transition face is four to five times of prior art and associativity is better, and it also avoid the situation that high temperature sealing-off is blown, electric conductivity is reliable.
Description
Technical field
The utility model relates to a kind of binding post, is specifically related to a kind of copper-aluminum transition connecting terminal being applicable to the upgrading of rural power grids and low voltage house wiring use.
Background technology
Along with the development of power construction, civilian power circuit upgrades gradually, and in household line, aluminum steel widely uses, and electric switch, indoor line etc. more use copper cash.Copper can not directly be connected with aluminium, and the loose contact etc. that copper aluminium is direct-connected exists electrochemical corrosion, thermal coefficient of expansion difference causes is easy to cause out a burnout failure, must use the mode that copper-aluminium transition connects.Copper-aluminium transition connects general with reference to GB/T14315-2008, but the copper-aluminum transition terminal form of this standard recommendation is more partial to non-civilian transmission line or industrial and mining enterprises use, and the small bore cylindricality copper-aluminum transition terminal that civilian aspect needs does not relate to.There is demand in reality, standard ununified again, buying in enormous quantities has difficulties, and is power office substantially, contact gold utensil producer of electric switch producer customizes, generally directly do not circulating on the market.Solution generally has two kinds, and a kind of is in the pipe portion of conducting terminal pours into and the conductive paste of current potential, and this life-span is shorter, and conductive paste several years afterwards inefficacy electrochemical corrosion exists.Another kind is that copper aluminium bar carries out friction welding, through Vehicle Processing, impact extrusion, forge shaping, program long service life but civilian small bore terminal material utilance generally only has 15% to 30%, scrappage is high, processing cost is high, long term overloading temperature raises time copper-aluminium transition face be separated open circuit.
Utility model content
The purpose of this utility model is to provide that a kind of copper-aluminium transition face is large, the reliable copper-aluminum transition connecting terminal of electric conductivity, is applicable to the upgrading of rural power grids and low voltage house wiring uses.
The utility model discloses a kind of copper-aluminum transition connecting terminal, employing copper-aluminum composite board is made, for the column single piece of internal layer aluminium, external sheath copper material, one end is the solid-section other end is hollow section, hollow section be cylindrical section for crimping outside line aluminum steel, the shape of solid-section is mated with house lead in air switch connected structure.
The overall dimension of described solid-section is less than the overall dimension of hollow section, is tapering transition section between solid-section and hollow section.
The utility model adopts Copper-Aluminum compound sheet material through stamping-out blanking, two to three drawing and once forges shaping, and the omnidistance punch press that uses is processed, and stock utilization and production efficiency significantly improve, and scrappage is low, and processing cost is low.Be the splicing ear of the hollow other end solid construction in one end after shaping, its copper-aluminium transition face is four to five times of prior art and associativity is better, and it also avoid the situation that high temperature sealing-off is blown, electric conductivity is reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A-A schematic diagram in Fig. 1.
Fig. 3 is that schematic diagram is looked on the right side of Fig. 1.
Embodiment
Present embodiment discloses a kind of copper-aluminum transition connecting terminal being applicable to 6-35 square of cross section of the upgrading of rural power grids and low voltage house use.As shown in Figure 1 to Figure 3, this binding post adopts copper coin aluminium sheet composite board to be made, for the single piece of internal layer aluminium, external sheath copper material, one end is the solid-section other end is hollow section, hollow section be cylindrical section for crimping outside line aluminum steel, the shape of solid-section is mated with house lead in air switch connected structure.The overall dimension of solid-section is less than the overall dimension of hollow section, is tapering transition section between solid-section and hollow section.
During making, Copper-Aluminum compound sheet material is through stamping-out blanking, two to three drawing and once forge shaping, and the omnidistance punch press that uses is processed, and stock utilization and production efficiency significantly improve, and scrappage is low, and processing cost is low.The copper-aluminium transition face of shaping rear splicing ear is four to five times of prior art and associativity is better, and it also avoid the situation that high temperature sealing-off is blown, electric conductivity is reliable.Forge mainly make solid-section profile and house lead in air switch on spliced eye form fit.
During use, hollow section crimps with outside line aluminum steel and is integrated, and compresses after the copper jack grafting on solid-section and house lead in air switch.
Claims (2)
1. a copper-aluminum transition connecting terminal, it is characterized in that: this binding post adopts copper-aluminum composite board to be made, for the column single piece of internal layer aluminium, external sheath copper material, one end is the solid-section other end is hollow section, hollow section be cylindrical section for crimping outside line aluminum steel, the shape of solid-section is mated with house lead in air switch connected structure.
2. copper-aluminum transition connecting terminal as claimed in claim 1, it is characterized in that: the overall dimension of described solid-section is less than the overall dimension of hollow section, is tapering transition section between solid-section and hollow section.
