Abstract
The utility model discloses an aluminium alloy strain clamp, comprising an aluminium alloy body provided with a wedge-shaped tension groove and an aluminium alloy creasing component, wherein the creasing component is provided with a wedge-shaped creasing area matched with the tension groove of the body and the wedge-shaped creasing area can slide to and fro in the tension groove of the body. A limiting notch is formed on an outer side end of the wedge-shaped tension groove. Sliding plates, of which the shapes are matched with those of the limiting notch, are arranged on the two side ends of the creasing component, the sliding plates are positioned in the limiting notch, and provided with anti-dropping areas for preventing from dropping out of the limiting notch at the inner and outer ends of the limiting notch. Made of the aluminium alloy with a high strength and corrosion resistance, the aluminium alloy strain clamp has the advantages of small volume and light weight, has no hysteresis power and eddy current loss and has a particularly outstanding energy-saving effect. In addition, the aluminium alloy strain clamp has a more rational structure and a more stable cable, and is more convenient to mount.
Description
Technical field
The utility model belongs to the electric armour clamp technical field, is specifically related to a kind of aluminium alloy strain clamp.
Background technology
The original strain clamp of China is based on the malleable cast iron material, and its material is than great, the wire clamp heaviness, to the aerial cable construction operation time, need to pack tightly wire external layer with aluminium-foil paper earlier, fastening with U-bolt, cause the formation closed magnetic loop, form magnetic hysteresis and eddy current, cause the wire clamp heating to limit ampacity and reduced mechanical strength, adopt the strain clamp of bolt arrangement, after lead is subjected to powerful long duration of action, creep extension can make the bolt looseness of initial installation, influences continuing of lead.
Summary of the invention
The purpose of this utility model provides the damp type conductor spacer that a kind of designs simplification, manufacturing process are simple and have better weakening performance.
The technical scheme that realizes the utility model purpose is: a kind of aluminium alloy strain clamp, comprise the aluminium alloy body and the aluminium alloy thread pressuring article that are provided with the wedge grip wire casing, described thread pressuring article is provided with the wedge shape line ball district that matches with body clamp groove, and described wedge shape line ball district can reciprocatingly slide in body clamp groove; The outboard end of described wedge grip wire casing is provided with a spacing breach, two side ends on the described thread pressuring article is provided with the slide plate that matches with spacing notch geometry, described slide plate is arranged in spacing breach, and described slide plate is equipped with and is used to prevent the anticreep district that drops from spacing breach being arranged in place, two ends inside and outside the spacing breach.
In the technique scheme, described thread pressuring article is provided with the closed pin through hole.
The utlity model has positive effect: (1) the utility model forms by adopting high strength, corrosion resistant aluminum alloy manufacturing, has little, the lightweight advantage of volume, and does not have magnetic hysteresis eddy current loss, and energy-saving effect is particularly remarkable.In addition, the utility model structure is comparatively reasonable, and cable is comparatively firm, and it is comparatively convenient to install.

Embodiment
(embodiment 1)
Fig. 1 is a kind of structural representation of the present utility model, has shown a kind of embodiment of the present utility model.Present embodiment is a kind of aluminium alloy strain clamp used when power circuitry engineering is constructed, comprise the aluminium alloy body 1 and the aluminium alloy thread pressuring article 2 that are provided with wedge grip wire casing 11, described thread pressuring article 2 is provided with the wedge shape line ball district 21 that matches with body 1 clamp groove 11, and described wedge shape line ball district 21 can reciprocatingly slide in body 1 clamp groove 11; The outboard end of described wedge grip wire casing 11 is provided with a spacing breach 111, two side ends on the described thread pressuring article 2 is provided with the slide plate 22 that matches with spacing breach 111 shapes, described slide plate 22 is arranged in spacing breach 111, and described slide plate 22 is equipped with and is used to prevent the anticreep district 23 that drops from spacing breach 111 being arranged in place, spacing breach 111 inside and outside two ends.
Described thread pressuring article 2 is provided with closed pin through hole 24, after cable was clamped, the position of described aluminium alloy body 1 and aluminium alloy thread pressuring article 2 is relative positioning also, and insert in alignment pin through hole 24 to closed pin through hole 24 this moment, can prevent that the two is shifted each other, cause cable loosening.
Present embodiment forms by adopting high strength, corrosion resistant aluminum alloy manufacturing, has little, the lightweight advantage of volume, and does not have magnetic hysteresis eddy current loss, and energy-saving effect is particularly remarkable.In addition, the present embodiment structure is comparatively reasonable, and cable is comparatively firm, and it is comparatively convenient to install.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
