Description
Technical field
The utility model relates to technical field of electric wires and cables, and more particularly, it relates to a kind of metal-shielded rubber sleeve cable.
Background technology
Metal sheathed cable is by increasing metal screen layer, and the electromagnetic wave producing while carrying out bucking current transmission and the extraneous a large amount of electromagnetic waves that exist, to reduce the normal work of Electromagnetic Interference electronic equipment, affect the performance of electronic equipment.The place for computer center, space center, intelligent building etc. with precise electronic, metering device, also requires the characteristic that has stronger anti-lightning and balanced current potential, improves power supply quality for metal sheathed cable.
At present, the Chinese patent that application number is 201320044847 discloses a kind of metal sheathed cable, and it comprises many master cores, the 4th core, insulating barrier, band, inner sheath, screen, protective sleeve; Described every master core and the 4th core are all wrapped up by insulating barrier described in one deck, described band is one and is wrapped in whole described insulating barriers, described inner sheath is wrapped in described band, and described inner sheath periphery is wrapped in oversheath, between described inner sheath and described oversheath, is provided with screen.Although this metal sheathed cable has stronger anti-electromagnetic interference anti-lightning and balanced current potential, improves the characteristic of power supply quality, the design of this core structure is unreasonable, and between it is adjacent, structural compactness is not strong, has affected the overall construction intensity of cable; Power cable is also mostly is in actual use because be mechanically damaged, to cause damaging, thereby need to strengthen the mechanical strength of whole cable.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of metal-shielded rubber sleeve cable, this metal-shielded rubber sleeve cable has improved the structural design of heart yearn, makes its structural compactness between adjacent strong, thereby has improved whole anti-mechanical strength.
For achieving the above object, the utility model provides following technical scheme: a kind of metal-shielded rubber sleeve cable, comprise cable inner core, and be wrapped in the cable outer layer outside cable inner core, described cable inner core comprises a plurality of sub-cable inner cores, the cross sectional shape of described sub-cable inner core is regular hexagon, and described sub-cable inner core is cellular distribution, and described every sub-cable inner core includes core conductor, be wrapped in insulating barrier outside core conductor, be coated on the metal screen layer outside insulating barrier; Described cable outer layer comprises the sheath that is coated on outside cable inner core, is coated on the steel-tape armouring outside sheath and is coated on the polyvinyl chloride oversheath outside steel-tape armouring; Between described sheath and cable inner core, be provided with filler.
By adopting technique scheme, the cross sectional shape of sub-cable inner core is to regular hexagon, described sub-cable inner core is cellular distribution, and cellular design has advantages of that structure is compacter, and such design has also improved the anti-mechanical strength of metal-shielded rubber sleeve cable integral body.
The utility model is further set to: described insulating barrier, the cross sectional shape of metal screen layer are regular hexagon.
By adopting technique scheme, insulating barrier, metal screen layer are all arranged to regular hexagon, can further improve the compactedness of structure, and then further improve anti-mechanical strength.
The utility model is further set to: described metal screen layer is rare-earth wires screen.
By adopting technique scheme, rare-earth wires screen is set and can more effectively overcomes the defect that causes electronic equipment cisco unity malfunction because of electromagnetic wave signal interference.
The utility model is further set to: described insulating barrier is crosslinked polyetylene insulated layer, and described filler is refractory glass fiber.
By adopting technique scheme, crosslinked polyetylene insulated layer and refractory glass fiber can improve flame-resistant insulation.
