Abstract
A copper-aluminum equipment wire clamp relates to the technical field of manufacture of a wire clamp used for fixing copper-aluminum transition connection between a wire and equipment in power transmission. The copper-aluminum equipment wire clamp comprises a wire pressing plate and a wire plate, wherein the wire plate includes an aluminum plate layer and a copper plate layer, the copper plate layer is melt and compounded on the lower surface of the aluminum plate layer, and a copper plate layer is melt and compounded on the upper surface of a portion, fixed together with equipment, of the wire plate. One surface, in contact with a fixing nut, of the wire clamp is not subject to electrochemical corrosion, the phenomena of poor contact and wire plate burning are avoided, and using safety and reliability are ensured.
Description
Technical field
The utility model relates to the manufacturing technology field of the wire clamp that is connected with the equipment copper-aluminium transition for securing electric lines in a kind of electric power transfer.
Background technology
Present wire clamp of copper-aluminum apparatus, as patent 201010224335.3, comprise tension disc, line plate, described tension disc is connected on the upper surface of described line plate by bolt, described line plate comprises aluminum layer, copper coin layer, and the fusion of described copper coin layer is compounded on the lower surface of described aluminum layer; At the equipment of some band copper screw bolts, as using wire clamp on the transformer, the wire clamp upper surface contacts with the locking copper nut, and couple corrosion easily takes place its contact-making surface, and is sticked together, and increases contact resistance, causes loose contact easily, even blows.
Summary of the invention
The utility model provides a kind of device clamp, and when purpose was to overcome existing copper screw rod, copper nut fixing clamper, couple corrosion easily took place its contact-making surface, the defective that safety, reliability are not high.
The utility model comprises tension disc, line plate, and described line plate comprises aluminum layer, copper coin layer, and the fusion of described copper coin layer is compounded in the lower surface of described aluminum layer, the compound layer of copper flaggy of upper surface fusion at the fixing position of described line plate and equipment.
The utility model is by at the upper surface of the fixed position of tension disc also compound layer of copper, like this when fixing clamper, the existing corrosion phenomenon of electrification can not take place in its one side that contacts with hold-down nut, and the phenomenon of having avoided loose contact and line plate to blow has guaranteed safety, the reliability used.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to view.
Among the figure, 1, tension disc, 2, the line plate, 3, bolt, 4, aluminum layer, 5, the copper coin layer.
Embodiment
As shown in Figure 1, this device clamp comprises tension disc 1, line plate 2, and tension disc 2 comprises aluminum layer 3, copper coin layer 5, and 5 fusion of copper coin layer are compounded in the lower surface of aluminum layer 2, the compound layer of copper flaggy 5 of upper surface fusion at the position that online plate 2 and equipment are fixing.
Claims (1)
1. wire clamp of copper-aluminum apparatus, comprise tension disc, line plate, described line plate comprises aluminum layer, copper coin layer, and the fusion of described copper coin layer is compounded in the lower surface of described aluminum layer, it is characterized in that the compound layer of copper flaggy of upper surface fusion at the fixing position of described line plate and equipment.
