Description

Novel copper stranded wire

Technical Field

The utility model relates to the technical field of copper stranded wires, in particular to a novel copper stranded wire.

Background

Copper stranded wire is a wire made of copper wires which are intertwined. The method is widely applied to outdoor places such as cables, steel network communication, electrified railways, subway light rails, railways and the like. Because the copper stranded wires are formed by stranded wires, when the copper stranded wire is used, due to the fact that the copper stranded wire conveying line is long, the copper stranded wires are only fixedly locked at the end portions of the copper stranded wires, and therefore the copper stranded wires located in the middle portion are prone to abnormal loosening and twisting, and normal use is affected.

Disclosure of Invention

Aiming at the problem that the middle conveying position of the existing copper stranded wire is easy to loose strands and twist, the utility model provides a novel copper stranded wire, which can reduce the abnormality of loose strands and twisting of the middle position of the long-conveying copper stranded wire.

The technical scheme is as follows: the utility model provides a novel copper stranded conductor, its includes copper stranded conductor body, its characterized in that: the copper stranded wire fixing device is characterized in that a fixing mechanism is arranged at an outer interval of the copper stranded wire body and comprises two circular-arc-shaped hoops which are connected in a hinged mode, a layer of rubber pad is arranged on the inner wall of each hoop, mounting lugs are arranged at the free ends of the two hoops, through holes are formed in the relative positions of the mounting lugs, and a positioning column penetrates through the two through holes of the mounting lugs and is locked through bolts perpendicularly connected with the positioning column.

It is further characterized by: the copper stranded wire body comprises an outer protective shell, an inner core and an outer core are arranged in the protective shell, the outer core is circumferentially distributed outside the inner core, and annular first sealing layers and annular second sealing layers are sequentially arranged at the gap between the outer part of the inner core and the protective shell;

an antioxidant layer is further arranged outside the first sealing layer;

and the outer parts of the inner core and the outer core are also provided with anti-corrosion coatings.

After the structure is adopted, as the fixing mechanism is arranged at the outer interval of the copper stranded wire, the fixing mechanism consists of two semi-arc hoops, when the copper stranded wire is installed, after the two hoops are surrounded, the positioning column passes through the installation lugs on the two hoops, and then the bolt is inserted for locking, so that the copper stranded wire is convenient to assemble and disassemble, and meanwhile, the phenomenon of loose strands at the middle position of the copper stranded wire can be effectively prevented.

Detailed Description

As shown in fig. 1 to 3, a novel copper stranded wire comprises a copper stranded wire body 1, a plurality of fixing mechanisms 2 are arranged at the outer interval of the copper stranded wire body 1, loose strand abnormality of the copper stranded wire body 1 can be prevented through the fixing mechanisms 2, the fixing mechanisms 2 comprise two circular arc-shaped anchor clamps 21 which are connected in a hinged mode, a layer of rubber pad 22 is arranged on the inner wall of each anchor clamp 21, the rubber pad 22 can play a role of preventing slipping and scratching the copper stranded wire body 1, mounting lugs 23 are arranged at the free ends of the two anchor clamps 21, through holes are formed in the relative positions of the mounting lugs 23, and positioning columns 24 penetrate through the through holes in the two mounting lugs 23 and are locked through bolts 25 which are vertically connected with the positioning columns. The fixing mechanisms 2 are arranged at intervals outside the copper stranded wire body 1, so that the copper stranded wire is convenient to install and arrange, and loose strand abnormality of the copper stranded wire body 1 can be effectively reduced after the copper stranded wire body is clamped.

Further, the copper stranded wire body 1 comprises an outer protective shell 11, an inner core 12 and an outer core 13 are arranged inside the protective shell 11, the outer core 13 is circumferentially distributed outside the inner core 12, annular first sealing layers 13 and annular second sealing layers 14 are sequentially arranged at gaps between the outer portion of the inner core 12 and the protective shell 11, and mounting grooves for wrapping the outer core 13 are formed in corresponding positions of the first sealing layers 13 and the second sealing layers 14. The first sealing layer 13 and the second sealing layer 14 can be made of polyurethane composite materials and can play a role in preventing corrosion. Meanwhile, the first sealing layer 13 and the second sealing layer 4 fill the gaps inside the protective shell 11, so that the abnormal phenomena of loose strands and twisting of the inner core 12 and the outer core 13 are further prevented.

Further, an antioxidant layer 15 is further provided on the outer portion of the first sealing layer 13, and the antioxidant layer 15 is made of a high temperature resistant antioxidant material.

Furthermore, the outer parts of the inner core 12 and the outer core 13 are respectively provided with an anti-corrosion coating 16, and the inner core 12 and the outer core 13 can be effectively prevented from being corroded by the anti-corrosion coating 16, so that the reliability of the copper stranded wire is improved.
