Abstract

The utility model discloses a special-shaped parallel groove clamp. The special-shaped parallel groove clamp comprises an upper clamping block, a lower clamping block and holding-down bolts. The upper clamping block is provided with a through hole, and the bottom surface of the upper clamping block is provided with two upper clamping grooves. The lower clamping block is provided with a run-through screw hole, and the upper surface of the lower clamping block is provided with two lower clamping grooves. The holding-down bolts pass through the through hole of the upper clamping block and the screw hole of the lower clamping block and is used to firmly connect the upper clamping block and the lower clamping block together. Each upper clamping groove and a corresponding lower clamping groove are combined to form a wire clamping hole. The special-shaped parallel groove clamp is characterized in that the through hole of the upper clamping block is a special-shaped hole, and the aperture of the middle section of the through hole is smaller than the apertures of openings at the upper and lower ends of the through hole. When the special-shaped parallel groove clamp of the utility model is in use, when two wires of different size specifications need to be connected, the two wires of different size specifications can be just compacted by the upper clamping block by rotating the upper clamping block or making the upper clamping block inclined at a certain degree, so that the application range of the special-shaped parallel groove clamp of the utility model can be effectively broadened.

Description

Special-shaped parrel-slot cable clamp
Technical field
The utility model belongs to the electric armour clamp technical field, is specifically related to a kind of Special-shaped parrel-slot cable clamp.
Background technology
At present, normally used parallel groove clamp in distribution line, its structure comprises fixture block, lower fixture block and hold-down bolt; The basal surface of described upper fixture block is provided with two upper fastening grooves, and the center is provided with open-work; The upper surface of described lower fixture block is provided with lower fastening groove, and the center is provided with the central bore that runs through; Described hold-down bolt passes the centre bore of the open-work of fixture block and lower fixture block and both is fastenedly connected; Described each upper fastening groove and a corresponding lower fastening groove are combined to form a clamp hole.
In prior art, the open-work of offering due to upper fixture block and hold-down bolt coupling, the size in the clamp hole of rear formation is relatively-stationary therefore upper fixture block and lower fixture block are harmonious, and has caused existing parallel groove clamp to support the use with the wire of default specification.
Summary of the invention
The purpose of this utility model is to provide a kind of Special-shaped parrel-slot cable clamp that is applicable to different size specification wires.
The technical scheme that realizes the utility model purpose is: a kind of Special-shaped parrel-slot cable clamp comprises fixture block, lower fixture block and hold-down bolt; Described upper fixture block is provided with open-work, and the basal surface of upper fixture block is provided with two upper fastening grooves; Described lower fixture block is provided with the screw that runs through, and the upper surface of lower fixture block is provided with two lower fastening grooves; Described hold-down bolt passes the screw of the open-work of fixture block and lower fixture block and both is fastenedly connected; Described each upper fastening groove and a corresponding lower fastening groove are combined to form a clamp hole; It is characterized in that: the open-work of described upper fixture block is a profiled holes, and the aperture of this open-work interlude is less than the aperture of this open-work up and down two side ends opening part.
In such scheme, the radial section shape of described upper fixture block open-work interlude is circular, and the radial section shape of its up and down two side ends opening part is kidney-shaped.
In such scheme, be equipped with double wedge in described upper fastening groove and lower fastening groove.
The utlity model has positive effect: the utility model is by arranging profiled holes in upper fixture block, and the aperture that makes this open-work interlude is less than the aperture of this open-work up and down two side ends opening part; In use, when needs connect two kinds of wires of different size specifications, can by rotating upper fixture block or perhaps the certain angle that tilts, make fixture block can just in time compress the wire of these two kinds of different size specifications, thereby effectively widen the scope of application of the present utility model.
Description of drawings
