Description

Deformation resistant cable

Technical field:

The utility model relates to a kind of deformation resistant cables.

Background technique:

Current electric wire or cable typically coats one layer of plastic peel by single piece of metal core wire and constitutes, and some occasions When needing more cables, carry out the cable for laying split conductor, due to cable use of split conductor in soil layer it is easy by Larger pressure, to be easy broken skin damage, service life is affected.

Summary of the invention:

The purpose of this utility model is to provide a kind of deformation resistant cable, the deformation resistant construction of cable is simple, design is reasonable, Be conducive to improve its anti-deformation.

The utility model deformation resistant cable, it is characterised in that: including two core wires disposed in parallel, envelope in two core wires The mica belt of periphery and the galvanized iron cortex being spirally wound on outside mica belt, galvanized iron cortex periphery extrusion molding have cable Exodermis, the galvanized iron sheet layer surface have convex ribs along galvanized iron sheet length direction array, and the convex ribs favour galvanized iron sheet Layer length direction.

Further, above-mentioned core wire includes conductive metal internal core wire and plastics cortex.

Further, the both sides of above-mentioned two core wires are equipped with the second core wire, and the line footpath of second core wire is core wire One third.

Further, above-mentioned second core wire discontinuity be located at galvanized iron cortex inner side and outer side.

Further, above-mentioned convex ribs are elongated, are laid in galvanized iron cortex two sides, and dislocation is set along its length It sets.

Further, above-mentioned convex ribs are by being stamped and formed out.

The utility model deformation resistant cable is formed by two parallel core wires, is conducive to make in the occasion of the multi-thread core of needs With mica belt two core wire peripheries increases its insulation performance；In galvanized iron sheet layer surface along galvanized iron sheet length side There are convex ribs to array, convex ribs favour galvanized iron cortex length direction, to be wrapped in mica belt periphery in galvanized iron cortex When, the frictional force of adjacent galvanized iron cortex can be increased, increase its anti-pressure-resistant performance, extend its service life.

Detailed description of the invention:

Specific embodiment:

The utility model deformation resistant cable include two core wires 1 disposed in parallel, envelope two 1 peripheries of core wire mica Belt 2 and the galvanized iron cortex 3 being spirally wound on outside mica belt, galvanized iron cortex periphery extrusion molding have cable exodermis 4, The galvanized iron sheet layer surface has convex ribs 5 along galvanized iron sheet length direction array, and the convex ribs favour galvanized iron cortex length Direction.

Further, in order to improve compressive property, above-mentioned core wire 1 includes conductive metal internal core wire 101 and plastics cortex 102。

Further, the both sides of above-mentioned two core wires are equipped with the second core wire 6, and the line footpath of second core wire is core wire One third.Second core wire also includes conductive metal inner core wire body 601 and plastic peel layer 602.

Further, in order to allow galvanized iron cortex to be bonded the side of two core wires, the position of above-mentioned second core wire discontinuity In galvanized iron cortex inner side and outer side, i.e., one section is located on the inside of galvanized iron cortex, and one section is located on the outside of galvanized iron cortex, can be Second core wire is located on the outside of the galvanized iron cortex of three circle of successively winding, positioned at the inside of the successively galvanized iron cortex of two circle of winding, Galvanized iron cortex is set more to fit in the sides of two core wires by the design；Can certainly the second core wire be respectively positioned on it is zinc-plated The inside of iron sheet layer and mica belt 2 (whole length direction is as shown in Figure 2).

In order to more preferably increase the frictional force and anti-deformation of adjacent galvanized iron cortex, above-mentioned convex ribs are elongated, cloth Galvanized iron cortex two sides are located at, and are shifted to install along its length.

In order to easy to make, for above-mentioned convex ribs 5 by being stamped and formed out, the width of the strip convex ribs is that galvanized iron cortex is zinc-plated Iron sheet width 1/6th, and the length of strip convex ribs is galvanized iron cortex galvanized iron sheet width one third, strip is convex Muscle and galvanized iron sheet length direction form 45 degree of angles, 0.5-1 times with a thickness of galvanized iron sheet thickness of punching press.

The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the patents it is equal Deng variation and modification, it should all belong to the covering scope of the utility model.
