Description
Technical field
This utility model relates to a kind of resist bending cable.
Background technology
Cable is usually by the cable of the stranded similar rope of several or several groups of wires (often organizing at least two), often mutually insulated between group wire, and is often twisted into round a center, and whole outside is surrounded by the cover layer of high-insulation.Cable has interior energising, the feature of external insulation.Cable has power cable, controls cable, compensating cable, shielded cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy cable etc..They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc..
The mode of production with most of electronic products that manufactures of electric wire is diverse.Electronic product generally adopt assemble parts into a unit, multiple parts refill and are made into separate unit product, product measures with number of units or number of packages.Electric wire is with length for basic measurement unit.All electric wires are all from conductor processing, make electric wire product plus insulation, shielding, stranding, sheath etc. layer by layer in the periphery of conductor.Product structure is more complicated, and the level of superposition is more many.Along with imbedded power cable sets up the developing rapidly of engineering, the requirements at the higher level that cable protection is proposed, cable protecting sleeve be adopt polythene PE and high-quality steel pipe through sandblasting ball blast pre-treatment, leaching is moulded or application, heating cure technique are made.It is a kind of electric insulating tube that protection electric wire and cable is the most frequently used.Because have that insulating properties are good, chemical stability is high, non-corrosive, not aging, be suitable for severe rugged environment and extensively applied.
Damaging easily occurs when bending in current existing cable, and structural strength is relatively low, and waterproof effect is not good.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of function being provided simultaneously with signal and electric current transmission, and resist bending is effective, and structural strength is high, the resist bending cable of good water-proof effect.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of resist bending cable, including optical fiber, corrugated tube, conductor and belting layer, described optical fiber is located in corrugated tube, described optical fiber is provided with more than one, described belting layer is located at outside conductor, described conductor is that hollow is arranged, it is provided with reinforcement in described conductor, described reinforcement is wound around by nylon yarn and forms, it is provided with emulsion layer between described corrugated tube and belting layer, described emulsion layer arranged outside has water blocking layer, screen layer, plumbous jacket layer, steel wire armor layer and sheath, and described water blocking layer, screen layer, plumbous jacket layer, steel wire armor layer and sheath are arranged successively from the inside to the outside.
As preferably, described corrugated tube is aluminium alloy corrugated tube, and corrugated tube can be not damaged in result under bending state.
As preferably, described jacket thickness is more than 4mm, and sheath can keep the construction of cable tight.
As preferably, described water blocking layer is connected with screen layer gluing, and water blocking layer has good waterproof effect.
As preferably, described corrugated tube diameter, more than 10mm, keeps the space that optical fiber is arranged in corrugated tube bigger.
The beneficial effects of the utility model are: be provided with reinforcement in the conductor of setting, and reinforcement is wound around by nylon yarn to form and structural strength can be kept high, resist bending；The optical fiber arranged is located in corrugated tube, it is possible to keeping cable to be provided simultaneously with signal and the function of electric current transmission, emulsion layer can keep will not being formed inside cable space, describes easily in bending time-varying simultaneously；The plumbous jacket layer arranged and steel wire armor layer keep structural strength high.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of resist bending cable of this utility model.
Detailed description of the invention
As shown in Figure 1, a kind of resist bending cable, including optical fiber 1, corrugated tube 2, conductor 3 and belting layer 4, described optical fiber 1 is located in corrugated tube 2, described optical fiber 1 is provided with more than one, described belting layer 4 is located at outside conductor 3, described conductor 3 is arranged in hollow, it is provided with reinforcement 5 in described conductor 3, described reinforcement 5 is wound around by nylon yarn and forms, it is provided with emulsion layer 6 between described corrugated tube 2 and belting layer 4, described emulsion layer 6 arranged outside has water blocking layer 7, screen layer 8, plumbous jacket layer 9, steel wire armor layer 10 and sheath 11, described water blocking layer 7, screen layer 8, plumbous jacket layer 9, steel wire armor layer 10 and sheath 11 are arranged successively from the inside to the outside.
Described corrugated tube 2 is aluminium alloy corrugated tube.
Described sheath 11 thickness is more than 4mm.
Described water blocking layer 7 is connected with screen layer 8 gluing.
Described corrugated tube 2 diameter is more than 10mm.
The beneficial effects of the utility model are: be provided with reinforcement in the conductor of setting, and reinforcement is wound around by nylon yarn to form and structural strength can be kept high, resist bending；The optical fiber arranged is located in corrugated tube, it is possible to keeping cable to be provided simultaneously with signal and the function of electric current transmission, emulsion layer can keep will not being formed inside cable space, describes easily in bending time-varying simultaneously；The plumbous jacket layer arranged and steel wire armor layer keep structural strength high.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model be not limited thereto, any change expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.
