Abstract

The utility model discloses a kind of stretch-proof cable; including outer jointing jacket, the armor 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 receiving spaces by the separating part; there is a cable core and a tension heart yearn in described each receiving space; the cable core and tension heart yearn are mutually stranded, and the cable core includes conductor, the screen layer outside conductor and the protective layer outside screen layer.Cable stretch-proof effect of the present utility model is good, and shield effectiveness is good.

Description

A kind of stretch-proof cable

Technical field

The utility model is related to field of cables, and in particular to a kind of stretch-proof cable.

Background technology

In various application scenarios widely, some are used for field of power transmission to cable, and some are used for field of signal transmissions, Cable often often has multiple cables core in the pulling force of outside, and a protective case for cable in use Line, multiple cable cores there may be situation about interfering with each other when in use.

Utility model content

Utility model purpose：The utility model is intended to overcome the defect of prior art, there is provided a kind of stretch-proof cable.

Technical scheme：A kind of cable, including outer jointing jacket, the armor in outer jointing jacket, in armor It is in cross separating part to have section in flame-retardant layer, the flame-retardant layer, and the separating part divides the flame-retardant layer inner space Being divided into has a cable core and a tension heart yearn, the cable core in 4 receiving spaces, described each receiving space Mutually stranded with tension heart yearn, the cable core includes conductor, the screen layer outside conductor and the guarantor outside screen layer Sheath.

Further, the separating part is made up of polyvinyl chloride, and many are distributed with separating part longitudinally along the cable The copper cash 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 heart yearn is made up of glass fibre.

Beneficial effect：Cable of the present utility model, tensile resistance is good, and each cable core can be avoided when using Interfere.

Brief description of the drawings

Fig. 1 is cross-section of cable schematic diagram.

Specific embodiment

Reference：1 outer jointing jacket；2 armors；3 flame-retardant layers；4 separating parts；4.1 copper wires；5 screen layers；6 protective layers；7 Tension heart yearn；8 conductors.

A kind of cable, including outer jointing jacket 1, the armor 2 in outer jointing jacket 1, the flame-retardant layer in armor 2 3, it is in cross separating part 4 to have section in the flame-retardant layer 3, and the separating part 4 separates the inner space of the flame-retardant layer 3 Into 4 receiving spaces, there is a cable core and a tension heart yearn in described each receiving space, the cable core and Tension heart yearn 7 is mutually stranded, and the cable core includes conductor 8, the screen layer 5 outside conductor 8 and outside screen layer 5 Protective layer 6.The separating part is made up of polyvinyl chloride, and many copper for extending longitudinally along the cable are distributed with separating part Line.The armor is steel wire armor layer.The flame-retardant layer is low-smoke non-halogen flame-retardant layer.The tension heart yearn is by glass fibre system Into.

Cable of the present utility model, due to there is separating part, so as to eliminate interfering between each cable core, And shield effectiveness is increased with copper wire in separating part, the interference between removing each.And each cable core and tensile core Line is stranded, increased stretch-proof effect.

Although the utility model is illustrated and described with regard to preferred embodiment, those skilled in the art should manage Solution, without departing from claim limited range of the present utility model, the utility model can be carried out various change and Modification.
