Abstract
A binding post for connecting an aluminium core cable and a copper bus bar is suitable for connection between aerial electric aluminium core cables and grid equipment copper bus bars. The binding post is welded by an aluminium binding head and a copper connecting sheet, the aluminium core of the cable is properly clamped by the aluminium binding head, and the copper connecting sheet is properly fastened with the copper bus bar by a bolt and a nut. The utility model has the shape features that the aluminium binding head is bent 90 degrees into an L shape, the force arm from the traction point of the aluminium core cable on the aluminium binding head to the aluminium and copper welding part is shortened, and traction bending force actually exerted at the aluminium and copper welding part by external traction force is accordingly reduced; the aluminium and copper welding part can be effectively prevented from bending and breaking.
Description
Technical field
The utility model is a kind of binding post that connects aluminium cable and copper line row, especially is applicable to the connection between the copper line row of similar built on stilts electric power aluminium cable and grid equipment.
Background technology
Overhead power transmission line commonly used often adopts the cable and wire of aluminium core, and the cable and wire and the copper bar of copper core are adopted in power transmission and distribution equipment end of incoming cables more, and this just will interconnect the cable and wire and the copper line row of aluminium core inevitably.Aluminium has different chemisms with copper, and the chemism of aluminium is high more a lot of than copper, they is simply linked together couple corrosion easily takes place.Time is long slightly, and the junction contact resistance can increase and generate heat, and the equipment that gently then influences normally moves, and is heavy then burn out equipment, even cause and have a power failure and fire incident.So aluminium cable generally directly is not connected with copper line row, needs between them to connect by the aluminum bronze binding post.The aluminum bronze binding post is welded by aluminum material crimp head and copper material brace, its aluminum material crimp head compresses mode with the aluminium core employing of cable and wire and is connected, and its other end copper material brace adopts bolt, nut fastening means to be connected with copper line row.Usually aluminium cable has bigger traction force to the aluminum bronze binding post.The shape and size of present being seen aluminum bronze binding post, the tractive force of aluminium cable pair of wire connection terminals is oversize to the arm of force of aluminum bronze weld, makes binding post aluminum bronze weld be subjected to excessive tractive bending force and easily ruptures.
The utility model content
In order to overcome the deficiency that existing aluminum bronze binding post its aluminum bronze weld when being subjected to tractive easily bends and ruptures, the utility model provides a kind of aluminum bronze binding post, this aluminum bronze binding post can bear bigger external force tractive, prevents its aluminum bronze weld bend fracture.The technical solution adopted in the utility model is: the shape that changes the aluminum material crimp head of aluminum bronze binding post, 90 ° of one-tenth of aluminum material crimp head bending are L shaped, shorten the arm of force of its aluminium cable wire pair aluminum material crimp head tractive force that connects to the aluminum bronze weld, thereby can obviously reduce tractive external force to the actual tractive bending force that applies of aluminum bronze weld, the aluminum bronze weld of binding post just is difficult for because of being subjected to the tractive fracture that bends.
The utility model is simple and practical, and it can bear bigger external force tractive, can effectively prevent its aluminum bronze weld bend fracture, has reliable connection aluminium cable and copper line row's beneficial effect.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a planform schematic diagram of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is existing aluminum bronze connection terminal structure shape schematic diagram.
Fig. 4 is the vertical view of Fig. 3, but the aluminum bronze weld among Fig. 4 ruptures.
Among the figure, 1 is the aluminium cable electric wire, 2 is the aluminum material crimp head, 3 is the aluminum bronze weld, 4 is the copper material brace, L1 be the utility model its tractive force of aluminium cable wire pair is to the arm of force of aluminum bronze weld when using, L2 is the arm of force of force, the fastening center of copper material brace to the aluminum bronze weld, its tractive force of aluminium cable wire pair was to the arm of force of aluminum bronze weld when L3 used for existing aluminum bronze binding post.
Embodiment
In order to shorten aluminium cable electric wire (1) arrives aluminum bronze weld (3) to the tractive force of aluminum bronze binding post the arm of force, to reduce tractive external force to the actual tractive bending moment that applies of aluminum bronze weld, the utility model adopts the planform as Fig. 1, and 90 ° of one-tenth of aluminum material crimp head bending are L shaped.The tractive bending force F that the utility model embodiment is subjected at the aluminum bronze weld
1Traction force F * (L that place ,=tractive force is subjected to
1/ L
2), and the tractive bending force F that existing aluminum bronze binding post is subjected at the aluminum bronze weld
2Traction force F * (L that place ,=tractive force is subjected to
3/ L
2).Because L
1Compare L
3Dwindled many, so F
1Compare F
2Reduce many.Also be the aluminum bronze binding post when being subjected to same external force tractive, the actual tractive bending force that is subjected to of the utility model aluminum bronze weld reduces about 2/3rds than existing aluminum bronze binding post.So the utility model can effectively prevent to make the fracture that bends of its aluminum bronze weld because of being subjected to the external force tractive.
Claims (1)
1. a binding post that connects aluminium cable and copper line row is made of aluminum material crimp head and the welding of copper material brace, and it is characterized in that: 90 ° of one-tenth of aluminum material crimp head bending are L shaped.
