Abstract
The utility model relates to a copper and aluminum device wire clamp. The copper and aluminum device wire clamp mainly solves the technical problems of easy fracture and the like, which are caused by electrochemical reaction which is generated when the junction of a copper wiring terminal of the existing copper and aluminum device wire clamp and an aluminum wire plate is electrified. The copper and aluminum device wire clamp is characterized in that a contact copper sheet is arranged on one side, which contacts a contact, of the lower end of a wire clamp plate; and the contact copper sheet and the wire clamp plate are in an integrated structure, and the contact copper sheet is even with the side of the wire clamp plate. The copper and aluminum device wire clamp provided by the utility model has the advantages that the contact copper sheet is arranged below the wire clamp plate; the side, which is fixed with the contact copper sheet, on the wire clamp plate is fitly connected with a device copper joint; the contact copper sheet is fitly fixed on the side of the wire clamp plate and the wire clamp plate is a whole body, so that the wire clamp plate does not fracture in use even electrochemical reaction occurs; the use strength and the reliability of the device wire clamp are ensured; the contact resistance is reduced; energy is saved; and the former copper contact is changed into the copper sheet, which can greatly reduce the use amount of copper and effectively reduces the production cost.
Description
Technical field
The utility model relates to a kind of jockey, relates in particular a kind of wire clamp of copper-aluminum apparatus, and the electric wire that is mainly used in power domain connects.
Background technology
Power industry, when defeated, distribution, for electric power being carried out liter, transformation or shunting, tends to by device clamp, electric wire is fixed, and then device clamp is connected with binding post defeated, controller switching equipment, guarantees the fail safe of electric power transfer; And existing wire clamp of copper-aluminum apparatus mainly by the aluminum steel plate with pressuring line groove, be arranged on pressing plate on pressuring line groove and clamping screw and form with the copper contact plate that the aluminum steel plate is welded as a whole, in order to guarantee the safety and reliability used, the copper contact plate is to utilize friction welding technological and aluminum steel plate to be welding as one; Adopt the wire clamp of copper-aluminum apparatus of this structure outwardly, intensity is very high, but in actual use, and the welding end surface place of copper tip and aluminum steel plate can produce electrochemical reaction and form couple corrosion, and easily fracture and increased contact resistance, waste energy; Secondly, adopt copper tip and the welding of aluminum steel plate, cost is relatively high.
The utility model content
In order to solve above technical problem, the utility model provides a kind of wire clamp of copper-aluminum apparatus, and this device clamp not only can be avoided copper aluminium contact position fracture, improves the working strength of wire clamp; Simultaneously, also can when at utmost reducing production costs, can also reduce contact resistance, reduce electricity and damage.
For solving above technical problem, the technical scheme that the utility model is taked is a kind of wire clamp of copper-aluminum apparatus, includes wireplint, in the upper end of wireplint, is provided with pressuring line groove, and the top of pressuring line groove is provided with the tension disc be connected with wireplint by clamping screw; Described wireplint lower end is provided with and contacts copper sheet with the one side of contact, and this contact copper sheet is structure as a whole with wireplint and is equal with the face of wireplint.
Further, described contact copper sheet thickness is to be welded as a whole between 0.5～1mm and with wireplint.
The beneficial effects of the utility model arrange the contact copper sheet below wireplint, like this when aluminum steel need to be connected with copper tip defeated, controller switching equipment, can first aluminum steel be inserted in the pressuring line groove of wireplint and drive tension disc that aluminum steel and wireplint are fixed by clamping screw, and then the one side of fixing contact copper sheet on wireplint is fitted and is connected with the equipment copper sleeve; Because the contact copper sheet is that laminating is fixed on the side of wireplint, wireplint is whole, even electrochemical reaction occurs during use, wireplint can not rupture yet, and working strength and the reliability of the device clamp so just guaranteed reduce contact resistance, the saving energy; Secondly, change original copper contact head into copper sheet, can greatly reduce like this use amount of copper, effectively reduce production costs.

The end view that Fig. 2 is a kind of wire clamp of copper-aluminum apparatus of the utility model embodiment
Embodiment
Below in conjunction with accompanying drawing, the utility model execution mode is described further:
As shown in Figure 1-2, the utility model is a kind of wire clamp of copper-aluminum apparatus, includes wireplint 1, in the upper end of wireplint 1, is provided with pressuring line groove 11, and the top of pressuring line groove 11 is provided with the tension disc 13 be connected with wireplint 1 by clamping screw 12; For solve existing wire clamp of copper-aluminum apparatus copper tip and produce the easy fracture of electrochemical reaction and increase contact resistance during the energising of the joint of aluminum steel plate, the technical problems such as electricity undermines have been improved, described wireplint 1 lower end is provided with and contacts copper sheet 14 with one side defeated, the distribution contact, and this contact copper sheet 14 is structure as a whole with wireplint 1 and is equal with the face of wireplint 1; Contact copper sheet 14 is set below wireplint 1, like this when aluminum steel need to be connected with copper tip defeated, controller switching equipment, can first aluminum steel be inserted in the pressuring line groove 11 of wireplint 1 and drive tension discs 13 that aluminum steel and wireplint 1 are fixed by clamping screw 12, and then the fixing one side that contacts copper sheet 14 on wireplint 1 is fitted and is connected with defeated, controller switching equipment copper sleeve; Because contact copper sheet 14 is that laminating is fixed on the side of wireplint 1, wireplint 1 is whole, even electrochemical reaction occurs during use, wireplint 1 can not rupture yet, working strength and the reliability of the device clamp so just guaranteed, reduce contact resistance, saves the energy; Secondly, change original copper contact head into contact copper sheet 14, can greatly reduce like this use amount of copper, effectively reduce production costs.
In the present embodiment, in order farthest to reduce production costs and to guarantee to contact the degree of being connected firmly of copper sheet 14 and wireplint 1, described contact copper sheet 14 thickness are to be welded as a whole between 0.5～1mm and by soldering and wireplint 1.
Above-described embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
