Description

A kind of soft special cable of anti-dragging

Technical field

The utility model is related to a kind of special cable, more particularly to a kind of soft special cable of anti-dragging.

Background technology

Currently, the special cable applied in the market uses cross-linked ethylene-tetrafluoroethene oversheath, for the smaller electricity of specification The shortcomings that cable needs to improve the ability of its anti-dragging using high-strength alloy conductor, above-mentioned cable is cross-linked ethylene-tetrafluoro second The wearability of alkene is bad, and its pliability is poor, is needing its performance of the occasion of frequent alternating bending that can be affected, In addition the anti-dragging performance of above-mentioned cable is also bad, if its manufacturing cost can be increased significantly using high-strength alloy conductor.

Utility model content

The purpose of this utility model is to provide a kind of soft special cables of anti-dragging.

The technical solution adopted in the utility model is：

A kind of soft special cable of anti-dragging, it is characterised in that：It is coated on including cable core II and successively outside cable core II Shielded layer III, restrictive coating III, the cable core II are made of 3 groups of control lines, 3 groups of signal wires and strengthening core, 3 groups of control Line, 3 groups of signal wires are arranged alternately successively to be twisted on strengthening core, and the control line includes cable core I and is coated on cable core I successively On shielded layer I, restrictive coating I, the cable core I is twisted by 3 single line cores, and the single line core is by inner wire I and cladding It is constituted in the insulating layer I outside inner wire I, the insulation that the signal wire includes inner wire II and is coated on successively outside inner wire II Layer II, shielded layer II, restrictive coating II.

The strengthening core is made of aramid fiber yarn, and the inner wire I is made by twisting by tinned wird, and the inner wire II is by plating Silver-copper wire is made by twisting, and the insulating layer I is made of perfluoroethylene-propylene material, and the insulating layer II is by polytetrafluoroethylene material It is made, the shielded layer I is made by aluminium-plastic tape is wrapped, and the shielded layer II is made of silver-gilt copper wire braiding, the shielding Layer III is made of tinned copper wire braiding, and the restrictive coating I, restrictive coating II, restrictive coating III are made of polyurethane material.

The advantages of the utility model：Restrictive coating extrusion is carried out using polyurethane material, the material wear ability is excellent, pliability Height, not only increases the wearability of cable, and improves the pliability of special cable, and using aramid fiber strengthening core, intensity is high, Material proportion higher-strength alloy conductor is light, and the anti-dragging ability of cable can be improved, prevent use when due to generation external force by its It breaks, and reduces cost, the material purchases period which uses is short, and production efficiency is high, while material is with resistance to High temperature, the features such as light-weight, flame retardant property is good, excellent in abrasion resistance, pliability are high, at low cost, it is suitable for commercial communication field.

Specific implementation mode

As shown in Figs. 1-3, a kind of anti-draggings softness special cable, including cable core II14 and it is coated on cable core II14 successively Outer shielded layer III9, restrictive coating III10, cable core II14 are made of 3 groups of control lines, 3 groups of signal wires and strengthening core, 3 groups of controls Line processed, 3 groups of signal wires are arranged alternately are twisted on strengthening core 11 successively, and control line includes cable core I13 and is coated on cable successively Shielded layer I3, restrictive coating I4 on core I13, cable core I13 are twisted by 3 single line cores 12, single line core 12 by inner wire I1 with And the insulating layer I2 being coated on outside inner wire I1 is constituted, signal wire includes inner wire II5 and is coated on successively outside inner wire II5 Insulating layer II6, shielded layer II7, restrictive coating II8.

Strengthening core 11 is made of aramid fiber yarn, and inner wire I1 is made by twisting by tinned wird, and inner wire II5 is twisted by silver-coated copper wire Conjunction is made, and insulating layer I2 is made of perfluoroethylene-propylene material, and insulating layer II6 is made of polytetrafluoroethylene material, shielded layer I3 It is made by aluminium-plastic tape is wrapped, shielded layer II7 is made of silver-gilt copper wire braiding, and shielded layer III9 is woven by tinned copper wire and made At restrictive coating I4, restrictive coating II8, restrictive coating III10 are made of polyurethane material.

The utility model application polyurethane material carries out restrictive coating extrusion, and the material wear ability is excellent, and pliability is high, not only The wearability of cable is improved, and improves the pliability of special cable, using aramid fiber strengthening core, intensity is high, material ratio Weight higher-strength alloy conductor is light, and the anti-dragging ability of cable can be improved, since the external force of generation is broken when preventing from using, and And cost is reduced, the material purchases period which uses is short, and production efficiency is high, while material has high temperature resistant, again The features such as amount is light, flame retardant property is good, excellent in abrasion resistance, pliability are high, at low cost, is suitable for commercial communication field.
