The break resistant copper-aluminum transition cable clamp is reasonable in structural design, enlarges contact area of copper and aluminum bases, can be fixed via rivets, can be applied on electric lines widely, can effectively avoid line faults caused by burnout and breakage of cable clamps and contacts, and plays an important role of guaranteeing safety of power grids and supplying power reliably.
Description
Technical field
The utility model relates to a kind of wire clamp that connects copper conductor and aluminium conductor, especially a kind of anti-copper-aluminium transition equipment cable clamp that fractures that is used for switch contact and transformer input and output binding post and outer guide line.
Background technology
Existing copper-aluminium transition equipment cable clamp, be combination about the copper aluminium base to be symmetrically welded form, production technology adopts friction welding or arc welding, but owing to wire clamp and reasons such as the contact contact-making surface is little, screw is loosening, chemical corrosions, cause contact resistance big, mechanical strength is little, when stressed when excessive or when having big electric current to flow through wire clamp, cause device clamp to fracture or burn, influence the ordinary production of enterprise.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of anti-copper-aluminium transition equipment cable clamp that fractures is provided.
The anti-copper-aluminium transition equipment cable clamp that fractures of the present utility model, be that aluminium sheet and copper coin by aluminum equipment wire clamp connects and composes, be provided with stiffener at the aluminium sheet of aluminum equipment wire clamp and the junction of copper coin, the aluminium sheet and the copper coin of stiffener and aluminum equipment wire clamp are all fixed with rivet, and described stiffener is a copper coin.
The anti-copper-aluminium transition equipment cable clamp that fractures of the present utility model, the aluminium sheet of aluminum equipment wire clamp and copper coin junction contact-making surface all are hierarchic structure, have rivet to fix on the cascaded surface that the cascaded surface of aluminum equipment wire clamp and copper coin overlaps into one relatively mutually, is connected.
The anti-copper-aluminium transition equipment cable clamp that fractures of the present utility model, be that aluminium sheet and copper coin by aluminum equipment wire clamp connects and composes, the aluminium sheet of described aluminum equipment wire clamp and copper coin all are the L type, have rivet to fix on the bottom surface that the L bottom surface of the aluminium sheet of aluminum equipment wire clamp and copper coin links into an integrated entity relatively, is connected.
As further improvement of the utility model, the screw thread that matches with bolt is arranged in the bolt hole of copper coin.
As further improvement of the utility model, be L shaped copper fixed contact at the other end of copper coin, on the copper fixed contact, bolt hole is arranged.
Aluminum equipment wire clamp link into an integrated entity with the copper fixed contact (connected mode and 1,2,3,5) identical, know clearly bolt between device clamp and the fixed contact of cancellation has not promptly had contact of some face and bolt; Do not have loose contact, loosening, phenomenon such as contact resistance is excessive, contact area is little, thereby stopped because the various accidents of isolating switch that loose contact causes between them.
The anti-copper-aluminium transition equipment cable clamp that fractures of the present utility model, the contact area of the copper aluminium base of reasonable in design, increase, fix with rivet simultaneously, the device clamp of this device can extensive use on power circuit, it can effectively be avoided because the line fault that wire clamp, contact burn, fracture and cause has important function to ensureing power grid security, reliable power supply.
Description of drawings
