Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, a kind of electrical power wiring wire clamp, it comprises C type body 1, described C type body interior be provided with the first clamp 2, second clamp 3, first clamp, the second clamp chuck respectively and form wire between C type body end and compress chamber 4.
As shown in Figure 2, the front end of the first clamp 2 is provided with the first chuck 21, is provided with axle sleeve 22 at afterbody, and this axle sleeve is major arc shape.
As shown in Figure 3, second clamp is made up of rotating shaft 31 and the second chuck 32, rotating shaft 31 inside is provided with axial hole 311, and the cross sectional shape of this axial hole 311 is the stacking axial hole that makes of multilayer isosceles trapezoid is sandwich construction, simultaneously has slot 312 between the bottom of axial hole 311 and rotating shaft surface.
As shown in Figure 3, the second chuck 32 is provided with axial tailgate 321, and the opposite side of axial tailgate 321 is provided with the plate 322 consistent with isosceles-trapezium-shaped.By reference to the accompanying drawings shown in 1, the second chuck 32 is inserted in the inner axial tailgate 321 simultaneously of axial hole 311 by plate 322 and is positioned at slot 312 and rotating shaft 31 and the second chuck 32 is achieved a fixed connection.
As shown in Figure 1, bolt hole 11 is provided with at the middle part of C type body, simultaneously see accompanying drawing 2, shown in accompanying drawing 3, at aforesaid axle sleeve 22, rotating shaft 31 and plate 322 have the bolt slot 4 corresponding with bolt hole, when shown by C type body 1 according to accompanying drawing 1, first clamp 2, after second clamp 3 is assembled, bolt hole 11 is through with bolt slot 4, clamping screw 5 is through bolt hole 11 and bolt slot 4 and on clamping screw 5, be provided with locking nut (locking nut is attached not shown), because axle sleeve 22 is in major arc structure, the movable end of clamping screw 5 is through axle sleeve 22, after locking nut locking, the outboard shafts jacket wall that locking nut is close to axle sleeve 22 realizes locking.
Described known by said structure, after second chuck 32 of the second clamp 3 and rotating shaft 31 are combined by grafting, the adjustment change of the second clamp 3 length is realized by the adjustment differing heights position of plate 322 in axial hole 311, the wire that can realize after the adjustable length of the second clamp 3 between second chuck 32 and C type body end compresses the change width in chamber 4, thus can adapt to the compression of different wire diameter wire.
Further; also known shown in 3 by reference to the accompanying drawings by foregoing description; when this wire clamp operationally; the edge of the slot 312 in rotating shaft can continue to exert a force to the local of axial tailgate 321; when wire is in the wild by bad weather sustained oscillations such as strong wind; axial tailgate 321 often can be ruptured by force part, causes power failure.For solving this technical problem, as shown in Figure 3, be provided with the side plate 313 extended to rotating shaft outside in the both sides of described rotating shaft slot 312, form axial tailgate clip slot 314 between biside plate, the width of axial tailgate clip slot 314 and the consistency of thickness of axial tailgate 321.By reference to the accompanying drawings shown in 1, after the second chuck 32 and the rotating shaft 31 of the second clamp are fixing, axial tailgate 321 is positioned at axial tailgate clip slot 312 inside and is clamped by the side plate 313 of both sides.After increasing said structure, side plate 313 forms chucking power to axial tailgate 321, and the lifting surface area of axial tailgate 321 is increased, and decreases the potential safety hazard that fracture occurs axial tailgate 321.
As illustrated in the accompanying drawings from 1 to 3, first chuck 21, second chuck 32 semicircular in shape, the diameter of the first chuck 21 and the second chuck 32 is less than or equal to the end diameter of the C type body of its correspondence respectively, when the first chuck 21 or the second chuck 32 are pushed into the extreme position near C type body end, the first chuck, the second chuck can enter in C type body end the fastening compression realized wire.
When reality manufactures, for alleviating the weight of this clamp, reduce the mass loading in supply line, C type body, the first clamp, the second clamp adopt aluminum material to make.But in actual power, the wire of high-tension line generally adopts aluminum steel to power, after this wire clamp and the wire of high-tension line compress and are connected, its material is consistent, can ensure stable contact conducting, but when carrying out descending power supply by high-tension line, the descending current supply line then copper cash that adopts is powered more, and namely this copper wires exists copper aluminium and contact the problem that oxidation reaction occurs after connecting with wire clamp, for solving this technical problem, the utility model adopts having structure to be solved.
As shown in accompanying drawing 1 and accompanying drawing 3, the inner surface of the second chuck 32 is provided with copper clad layers 51, and is also provided with copper clad layers 51 at the terminal interior surface of the C type body of the second chuck 32 correspondence, and the copper clad layers of C type body end extends in the middle part of C type body.As shown in accompanying drawing 1 and accompanying drawing 3, the position being provided with copper clad layers 51 forms Lv Zhi basic unit 52 and copper clad layers 51 double-layer structure.On the inner surface that the position of certain copper clad layers 51 also can be arranged on the first chuck 21 and the terminal interior surface of the C type body of the first chuck 21 correspondence, as long as ensure that the inner surface of a chuck be the inner surface of another chuck of aluminium matter is the copper conversion that can realize between copper aluminium.
During making, the thickness of the thickness of copper clad layers 51 and the Lv Zhi basic unit 52 bottom it is consistent.
But copper clad layers 51 continuing to pull and be easy to copper clad layers 51 and wire to extract out by wire clamp at work due to wire is simply set in Lv Zhi basic unit 52, namely copper clad layers 51 is slided in Lv Zhi basic unit 52, causes copper clad layers 51 to produce with Lv Zhi basic unit 52 and is separated.For solving this problem, as shown in Figure 4, on Lv Zhi basic unit 52 faying face with copper clad layers 51
Further, for preventing sliding between copper clad layers and the Lv Zhi basic unit bottom it, described copper clad layers and Lv Zhi basic unit are provided with interlaced projection 521 and groove 522, the enlightenment of 4 with reference to the accompanying drawings, to arrange and projection 521 and groove corresponding to groove 522 and projection equally on the contact-making surface of copper clad layers 51 with Lv Zhi basic unit 52, such copper clad layers 51 and Lv Zhi basic unit 52 are formed after compressing and combining inlays state, cannot produce the changing of the relative positions between copper clad layers 51 and Lv Zhi basic unit 52.
Adopt said structure, not only can prevent from, between copper clad layers 51 and Lv Zhi basic unit 52, the changing of the relative positions occurs, also can increase the contact area between copper clad layers 51 and Lv Zhi basic unit 52 simultaneously further, ensure the stable transition between copper aluminium.
In the present embodiment, as shown in Figure 4, the shape of projection 521 and groove 522 is rectangular, certainly also can be made as circle or taper.
