Abstract
The utility model discloses a three-core twisted-pair reinforcement cable applied to an instrument. The cable comprises main wire cores, a flame retardant non-woven belt wrapping layer, an insulating layer, a nickel plated copper wire braided shielding layer and a sheath, wherein the flame retardant non-woven belt wrapping layer, the insulating layer, the nickel plated copper wire braided shielding layer and the sheath successively wrap the main wire cores. Each main wire core is composed of three twisted-pair insulating wire cores. The main wire cores are pairwise circumscribed and are closely arranged. A space between the flame retardant non-woven belt wrapping layer and the main wire cores are wrapped by a reinforcement part. The cross section of the reinforcement part is an equilateral triangle. A waterproof layer is arranged between the nickel plated copper wire braided shielding layer and the sheath. The cable can be widely used, has the advantages of good conductivity, water and moisture resistance, high temperature resistance, oil and acid resistance, drag resistance, winding resistance, breakage resistance, firm wire cores and the like, and is mainly applied to the instrument and other fields.
Description
Technical field
The utility model belongs to field of cables, relates in particular to a kind of instrument three core pair twists and strengthens cable.
Background technology
At present, along with the continuous increase of cable consumption, the quality of cable is also proposed to high requirement.Such as instrument cable, high temperature resistant to cable, waterproof oil resistant, anti-pulling, acid and alkali-resistance, the requirement of the aspect such as corrosion-resistant and anti-interference is all high especially.The permeability of the restrictive coating that common igelite is made is stronger, easily makes moist, and causes inner oxidation, affects normal signal transmission, has shortened the useful life of whole cable.Traditional cable core generally adopts lapping layer to hold, and core easily departs from former desired location in the situation that extraneous extrusion ratio is stronger.Only meet the requirements, just can better ensure the production and application of cable.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model be to provide a kind of both had waterproof moisture-proof, high temperature resistant, core firmly, anti-ly pull, the three core pair twists reinforcement cables for instrument of anti-interference, oil resistant acid-proof, the advantage such as anti-oxidant.
The utility model takes following technical scheme to realize: a kind of instrument is strengthened cable with three core pair twists, it comprises master core and is wrapped in successively the fire retardant nonwoven fabric belts lapping layer in master core outside, insulating barrier, nickel plating copper wire woven shield, sheath, described master core is to be formed by three insulated wire cores pair twists, described master core is circumscribed between two closely arranges, between described fire retardant nonwoven fabric belts lapping layer and described master core, wrap up reinforcement, described reinforcement cross section is an equilateral triangle, between described nickel plating copper wire woven shield and described sheath, be provided with watertight composition.
The core that described insulated wire cores is closed by multiply anaerobic annealed copper skein silk and be wrapped in the fluorubber skinning cortex in core outside, the outer conductor of tinned copper wire braiding forms.
Described reinforcement three limits are tangent with described insulated wire cores circumference respectively, and described reinforcement is by the netted inserts extrusion molding of poly-methyl trifluoro propyl siloxanes that adds micaceous organic silicon ribbon.
Described insulating barrier is to adopt the not fluorubber of drip filling glue, and a ground connection core and a drainage thread are also wrapped up in inside.
Described sheath is by the extraordinary butyronitrile compound material of the import extrusion molding that adds alumina silicate, anti-ointment, anticorrosive.
The utlity model has in sum following beneficial effect: this kind of cable applications is extensive, conduct electricity very well, waterproof moisture-proof, high temperature resistant, oil resistant acid-proof, is mainly used in the fields such as instrument, resistance to towing, resistance to coiling, anti-broken string, meanwhile, core is firm, effectively prevent core not to be subject to extraneous extruding and depart from former desired location, having ensured that cable uses safety.

Embodiment
As shown in Figure 1, a kind of special flexible frequency conversion private cable, a kind of instrument is strengthened cable with three core pair twists, it comprises master core 1 and is wrapped in successively the fire retardant nonwoven fabric belts lapping layer 3 in master core 1 outside, insulating barrier 4, nickel plating copper wire woven shield 6, sheath 8, described master core is 1 to be formed by three insulated wire cores pair twists, described master core 1 is circumscribed between two closely arranges, between described fire retardant nonwoven fabric belts lapping layer 3 and described master core 1, wrap up reinforcement 2, described reinforcement 2 cross sections are equilateral triangles, between described nickel plating copper wire woven shield 6 and described sheath 8, be provided with watertight composition 7.
The core that described insulated wire cores is closed by multiply anaerobic annealed copper skein silk and be wrapped in the fluorubber skinning cortex in core outside, the outer conductor of tinned copper wire braiding forms.
Described reinforcement 2 three limits are tangent with described insulated wire cores circumference respectively, described reinforcement is by the netted inserts extrusion molding of poly-methyl trifluoro propyl siloxanes that adds micaceous organic silicon ribbon, core is firm, effectively prevent core not to be subject to extraneous extruding and depart from former desired location, having ensured that cable uses safety.
Described insulating barrier 4 is to adopt the not fluorubber of drip filling glue, and a ground connection core 5 and a drainage thread 9 are also wrapped up in inside.
Described sheath 8 is that allowing cable work maximum temperature is 135 DEG C by the extraordinary butyronitrile compound material of the import extrusion molding that adds alumina silicate, anti-ointment, anticorrosive.
The permission bending radius of this cable is the outside diameter of cable 15 times; This cable allows reversed bending 7,000,000 times.
The above is embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
