Abstract
The utility model relates to a copper-aluminium transition connection terminal for electric power devices. The utility model comprises a copper plate part and an aluminium wiring part, wherein, the copper plate part is connected with an external wiring rod of an electric power device, and the aluminium wiring part is connected with external aluminium wires. The aluminium wiring part is provided with a swing bolt assembly, and both sides of the upper part of a swing head of a swing bolt are respectively provided with a wing plate which is extended in the axial direction of a swing hole, and thereby, a T-shaped swing bolt is formed. The lower bottom face of each of the two wing plates is corresponding to the wiring faces of an aluminium wiring body so that a wire clamp is formed. At wiring time, the external aluminium wires penetrate through the swing hole of the swing bolt, and then a screw cap is screwed down.
Description
The utility model relates to a kind of binding post, particularly a kind of copper-aluminium transition binding post that is used for power equipment.
Existing copper-aluminium transition binding post mainly contains the compression-type connection and screw bolt-type connects dual mode.With regard to screw bolt-type connected, its structure was made up of the copper coin that links to each other with the power equipment junction pole and aluminum steel wiring clamping plate two parts, and aluminum steel wiring clamping plate generally all will be provided with several bolts and clamp aluminum steel, so that fitting operation seems is very inconvenient.
Task of the present utility model provides the copper-aluminium transition binding post that a kind of fitting operation is used for power equipment easily.
The solution that realizes the utility model task is: the copper-aluminium transition binding post that is used for power equipment that is provided comprises copper coin part that links to each other with the external junction pole of power equipment and the aluminum wiring part that is connected outside aluminum steel.Said aluminum wire connecting portion is arranged with an eyelet bolt assembly, wherein respectively there is a wing plate that extends axially out along the movable joint hole both sides, movable joint head top of eyelet bolt, form T shape eyelet bolt, the bottom surface of this two wing plate is provided with the groove that can place aluminum steel, and relative with the wiring face of aluminum wiring body, form a wire clamp.Only need outside aluminum steel is passed the movable joint hole of eyelet bolt during wiring, tightening nuts gets final product then.
The utility model has the advantages that relatively simple for structure, and easy to operate.Since on eyelet bolt, be provided with wing plate, thus big with the aluminum steel contact-making surface, conduct electricity very well.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Fig. 1 is the structure chart of an embodiment of the utility model.
Fig. 2 is the left view of Fig. 1.
As shown in Figure 1 and Figure 2: porose 2 on the copper plate 1, it is used to connect the external junction pole of power equipment.Aluminum wiring part 3 is to do raw material with aluminium strip to bend to U-shaped, and its bottom has bolt hole, and its side has an extension 4, and extension 4 is welded as a whole with copper plate 1.This moulding both had been convenient to increase the contact area with aluminum steel, was convenient to utilize pressing equipment to produce in enormous quantities again.Axially respectively there is a wing plate 6 the head both sides of eyelet bolt 5 along the movable joint hole, form tommyhead bolt, and the bottom surface of wing plate 6 has semicircular arc groove, be used to push down aluminum steel 7, during wiring aluminum steel 7 is passed the movable joint hole of bolt 5, fastening nut 8 then, just aluminum steel can be clamped.Wing plate 6 on the bolt 5 can increase the contact-making surface with aluminum steel, thereby has guaranteed with aluminum steel good electrical contact is arranged.
