Abstract
The utility model discloses a four-core strain clamp, which comprises a wedged pulling plate, two wire clamping devices arranged on the upper and lower sides of the pulling plate, and a bolt fastening component. Each of the pulling plate and the wire clamping device is provided with a fastening hole. The bolt fastening component penetrates through the fastening holes, and fastens the wire clamping devices on the pulling plate. Each wire clamping device comprises a base, an upper cover and a gland, wherein the base is arranged adjacent to the pulling plate; the upper cover is pressed against the base; the gland is pressed against the upper cover; a clamping groove is formed on each of the base and the upper cover, and the clamping grooves are clamped to form a wire clamping hole; an elastic element is arranged between the upper cover and the base; and one end of the elastic element is pressed against the upper cover, and the other end of the elastic element is pressed against the base. The four-core strain clamp is compact and rational in structure and fully adapted to the structural characteristics of a bunched cable, and has the advantage of strong holding strength; in addition, the elastic elements are arranged between the upper covers and the bases, and can separate the upper covers from the bases to facilitate the penetration of the cable, and due to the existence of the elastic elements, the four-core strain clamp also has the advantage of preventing the loosening of the bolt fastening component.
Description
Technical field
The utility model belongs to the electric armour clamp technical field, is specifically related to a kind of four-core strain clamp.
Background technology
Bunched cable is to compare with respect to traditional bare wire, is a kind of brand-new service cable, and bunched cable can improve higher safety and reliability, and reduces the operating cost of installing, safeguarding, obtains at home at present day by day using widely.
Mostly the existing strain clamp that is used for bunched cable is to improve from the strain clamp that traditional bare wire uses, and weak point is that grip is less, construction inconvenience, and its structure remains at improvements.
Summary of the invention
The purpose of the utility model provide a kind of structure comparatively rationally, grip is big and construction four-core strain clamp comparatively easily.
The technical scheme that realizes the utility model purpose is: a kind of four-core strain clamp; Comprise the wedge shape arm-tie, be arranged on arm-tie up and down two wire-clamping devices and the bolted assembly of both sides; Said arm-tie and wire-clamping device are equipped with fastener hole, and said bolted assembly passes fastening open-work and is fastened on wire-clamping device on the arm-tie; Said each wire-clamping device comprises base, loam cake and gland, and said base is in abutting connection with the arm-tie setting, and said loam cake is pressed on the base, and said gland is pressed on and covers; Said base and on cover and be equipped with two and be used for the clip slots that clamping forms the clamp hole; Be provided with elastic component between said loam cake and the base, an end of said elastic component is pressed on and covers, and the other end is pressed on the base.
In the such scheme, said base or on cover and be provided with positive stop lug boss, said elastic component is the screw thread spring, said spring housing is located on the corresponding positive stop lug boss.
In the such scheme, the fastener hole on the said arm-tie is a mounting hole.
In the such scheme, also comprise pull bar, said pull bar rotates and is arranged on the arm-tie.
In the such scheme, said arm-tie adopts metal to process, and its outer wall is provided with insulating coating.
The utility model structure is compact and reasonable comparatively, fully adapts to the design feature of bunched cable, has the bigger advantage of grip; In addition, through between loam cake and base, elastic component being set, this elastic component can strut loam cake and base, be convenient to cable and pass, and because the existence of elastic component also can be played the advantage that prevents that the bolted assembly is loosening.
