Abstract
The utility model discloses a strain fitting of a composite material flexible aluminum stranded conductor, comprising an outer liner and a spiral steel anchor. The spiral steel anchor is connected with an outer conical ring of which the end part is equipped with a screw thread part, the appearance is cylindrical and the interior is equipped with a conical cavity, the outer conical ring is equipped with an inner conical ring which is equipped with a central radial through hole, and the diameter of the central radial through hole is less than the outer diameter of a composite core of the composite material flexible aluminum stranded conductor; the two shaft ends of the inner conical ring are respectively and inwards equipped with gaps having certain distances with the relative shaft ends along a radial direction, the front part of the outer liner is equipped with an inner liner which is extended out of the main body of the outer liner, and the inner diameter of the inner liner is slightly greater than the outer diameter of the composite material flexible aluminum stranded conductor. The inner liner plays a buffer part during the pressure welding process, so that a core rod is not crushed, cracked, peeled, bent, etc., the moderate grip strength of the core rod is guaranteed, and the performance of the core rod is not affected, and accordingly, the good grip strength and electric conduction capability between the composite material flexible aluminum stranded conductor and the strain fitting are guaranteed.
Description
Technical field
The utility model relates to a kind of strain insulator gold utensil, relates in particular to the soft aluminium stranded conductor strain insulator of a kind of composite material gold utensil.
Background technology
In built on stilts power cable system, need cable or the stretch-draw of bunched cable two ends be fixed on bar, tower or other bearing, use the strain insulator gold utensil, it is as electric conductor, and bears whole tension force of power cable.Conventional strain insulator gold utensil mainly is used in the connection of steel reinforced aluminium conductor; And the composite core of the soft aluminium stranded conductor of composite material is a fragile material; Its bending strength, tensile strength, and anti-extrusion ability little, therefore, the conventional gold utensil that continues can not be used for the connection of the soft aluminium stranded conductor of composite material.
Summary of the invention
The purpose of the utility model is to provide the soft aluminium stranded conductor strain insulator of a kind of composite material gold utensil, is used to connect the soft aluminium stranded conductor of composite material, and is simple to operate, guarantee that the plug grip is moderate, do not influence the performance of plug.
To achieve these goals; The utility model technical scheme realizes: the soft aluminium stranded conductor strain insulator of a kind of composite material gold utensil; Comprise outer liner tube, spiral steel anchor, described spiral steel anchor is provided with the threaded portion with the end, profile is that cylinder, inside are connected for the outer conical ring of conical cavity; The interior conical ring of center radial direction through hole is set in the described outer conical ring; The center radial hole diameter of conical ring is less than the external diameter of the soft aluminium stranded conductor composite core of composite material in said, and interior conical ring two axial ends radially inwardly is provided with one respectively has the gap of certain distance with relative axle head; The front portion of outer liner tube is provided with internal lining pipe, and internal lining pipe stretches out outside the outer shirt tube body, and the internal diameter of internal lining pipe is slightly larger than the external diameter of the soft aluminium stranded conductor of composite material.
Further, between described outer liner tube and spiral steel anchor drainage plate is set.
Further, described spiral steel anchor end is provided with the U-shaped link.
The soft aluminium stranded conductor of composite material inserts from the internal lining pipe of the front portion of outer liner tube, and the composite core of aluminium stranded conductor penetrates interior conical ring, and interior conical ring is in the outer conical ring; The radial clearance of interior conical ring is in the distortion of stressed back; Clamp composite core, anterior internal lining pipe crimping, internal lining pipe plays cushioning effect in the crimping process; Can not cause plug crushing, cracking, peeling, bending etc.; Guarantee that the plug grip is moderate, do not influence the performance of plug, finally guarantee to have good grip and conductive capability between soft aluminium stranded conductor of composite material and strain insulator gold utensil.
