Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment of the bus-duct connector of the utility model, as shown in Figure 1, transmission system includes 1 He of bus duct The bus-duct connector 2 of bus duct is connected, busbar 11 is stretched out at divergent shape in bus duct both ends, and the ends bent of busbar 11 is at approximation Parallel structure connects in order to pass through bus-duct connector 2.
As shown in Fig. 2, bus-duct connector 2 includes the spaced apart insulating barrier 21 of multiple through-thickness and is embedded in Electric conductor 22 on insulating barrier, the two sides of 21 stacking direction of insulating barrier are equipped with backplate 23, be equipped among insulating barrier 21 every Plate is perforated, and electric conductor is equipped among electric conductor 22 and is perforated, and partition and electric conductor are carried out tightly by fastening bolt 24 therethrough Consolidate and electric conductor 22 is made to clamp busbar 11, fastener of the composition of fastening bolt 24 across partition perforation and electric conductor perforation, backplate Platen 25 is provided between 23 and fastening bolt 24.
Insulating barrier 21 includes being located at the side insulating barrier 211 of two sides and being located in the middle intermediate insulation partition 212, is led Electric body 22 is embedded in the two sides of intermediate insulation partition 212 and the side of the insulating barrier 212 towards the middle of side insulating barrier 211. Busbar 11 not enough causes busbar 11 and 22 contact area of electric conductor insufficient because of bending precision in order to prevent, as shown in Figure 3 and Figure 4, Electric conductor 22 in the present embodiment is made of the copper strips stacking of 0.1mm, electric conductor 22 easily deform so that electric conductor 22 with Busbar 11 fits closely, and increases the contact area of busbar 11 and electric conductor 22, prevents and contact because of busbar 11 with electric conductor 22 Area deficiency causes resistance excessive, caused by localized hyperthermia, the security risks such as fire.For the ease of constitute electric conductor copper strips it Between be connected and fixed, the both sides along its length of the electric conductor in the present embodiment carry out tin plating processing in other embodiments can also The coat of metal is not used with zinc-plated or other coats of metal of use or.In other embodiments, electric conductor can also use other Thickness, such as the copper strips stacking of 0.15mm thickness are made.
