Abstract
The invention discloses a kind of stretch-proof cables; armor including outer jointing jacket, in outer jointing jacket, the flame-retardant layer in armor; it is in cross separating part to have section in the flame-retardant layer; the flame-retardant layer inner space is separated into 4 accommodation spaces by the separating part; there is a cable core and a tension core wire in each accommodation space; the cable core and tension core wire are mutually twisted, and the cable core includes conductor, the shielded layer outside conductor and the protective layer outside shielded layer.The cable stretch-proof effect of the present invention is good, and shield effectiveness is good.
Description
Technical field
The present invention relates to field of cables, and in particular to a kind of stretch-proof cable.
Background technology
Cable is very extensive in various application scenarios, some are used for field of power transmission, some are used for field of signal transmissions,
Cable often faces the pulling force of outside in use, and often has multiple cables core in the protective case of a cable
Line, there may be situations about interfering with each other when in use for multiple cable cores.
Invention content
Goal of the invention：The defects of the present invention is directed to overcome the prior art, provides a kind of stretch-proof cable.
Technical solution：A kind of cable, armor including outer jointing jacket, in outer jointing jacket, in armor
Flame-retardant layer, the flame-retardant layer is interior to have section in cross separating part, and the separating part divides the flame-retardant layer inner space
4 accommodation spaces are divided into, there is a cable core and a tension core wire, the cable core in each accommodation space
Mutually twisted with tension core wire, the cable core includes conductor, the shielded layer outside conductor and the guarantor outside shielded layer
Sheath.
Further, the separating part is made of polyvinyl chloride, and more are distributed in separating part longitudinally along the cable
The copper wire of extension.
Further, the armor is steel wire armor layer.
Further, the flame-retardant layer is low-smoke non-halogen flame-retardant layer.
Further, the tension core wire is made of glass fibre.
Advantageous effect：The present invention cable, tensile resistance is good, and using when can avoid the mutual of each cable core
Interference.
Description of the drawings
Fig. 1 is cross-section of cable schematic diagram.
Specific embodiment
Reference numeral：1 outer jointing jacket；2 armors；3 flame-retardant layers；4 separating parts；4.1 copper wire；5 shielded layers；6 protective layers；7
Tension core wire；8 conductors.
A kind of cable, the armor 2 including outer jointing jacket 1, in outer jointing jacket 1, the flame-retardant layer in armor 2
3, the flame-retardant layer 3 is interior to have section in cross separating part 4, and the separating part 4 separates 3 inner space of flame-retardant layer
Into 4 accommodation spaces, there is a cable core and a tension core wire in each accommodation space, the cable core and
Tension core wire 7 is mutually twisted, and the cable core includes conductor 8, the shielded layer 5 outside conductor 8 and outside shielded layer 5
Protective layer 6.The separating part is made of polyvinyl chloride, and the more copper extended longitudinally along the cable are distributed in separating part
Line.The armor is steel wire armor layer.The flame-retardant layer is low-smoke non-halogen flame-retardant layer.The tension core wire is by glass fibre system
Into.
The cable of the present invention since there are separating parts, so as to eliminate interfering with each other between each cable core, and divides
Shield effectiveness, the interference between removing respectively are increased every having copper wire in portion.And each cable core and tension core wire twist
It closes, increases stretch-proof effect.
Although the present invention is illustrated and has been described with regard to preferred embodiment, it is understood by those skilled in the art that
Without departing from scope defined by the claims of the present invention, variations and modifications can be carried out to the present invention.
