Abstract
The utility model discloses a signal transmission control cable, comprising an oversheath, the inner of which is provided with an armoring steel belt layer; the inner of the armoring steel belt layer is provided with an inner sheath; the inner of the inner sheath is provided with a shielding layer; the inner of the shielding layer is provided with a plurality of cable cores; a polyester tape lapping bag is arranged among the cable cores and the shielding layer; each cable core comprises a wire core set and an insulating layer. According to the mode, the signal transmission control cable can raise cable shielding property, has a firm structure and is not easy to damage.
Description
Technical field
The utility model relates to the control field of cables, particularly relates to a kind of signal transmission control cable.
Background technology
The control cable is used for the occasion that ac rated voltage 450/750V and following control, monitoring loop and protection circuit etc. need shielding; as the connection between all kinds of electrical instrumentations and the automation equipment; play the various electric energy of transmission or signal effect, make whole electric system obtain safe and reliable operation.
The control cable namely refers to braiding or wrapped one deck screen outside cable insulation, in order to reduce the interference of electric current in the outer bound pair insulating barrier, also reduce simultaneously the magnetic field influence to external world that electric current produces in the insulating barrier, be applicable to the jamming-proof various electrical equipment that requires of various alternating current-direct currents, as circuit connection of instrument, telecommunications, computer network control system, power equipment and automation equipment thereof etc.The deriving of electric wire/new product mainly be in response to occasion, application requirements is different and the convenience of equipment and reduce the requirement of equipment cost etc., and adopt new material, special material or change product structure or improve technological requirement and produce.Though existing control cable has shielding properties, its structure is often soft, uses for a long time to be easy to cause the cable body fracture.
The utility model content
The technical problem that the utility model mainly solves provides a kind of signal transmission control cable, can improve the shielding properties of cable, and sound construction is not fragile.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of signal transmission control cable is provided, comprise: oversheath, be provided with the armouring tape layer in the described oversheath, be provided with inner sheath in the described armouring tape layer, be provided with screen in the described inner sheath, be provided with a plurality of cable cores in the described screen, it is wrapped to be provided with polyester belt between described cable core and the screen, and described each cable core comprises core group and insulating barrier.
In preferred embodiment of the utility model, described steel-tape armouring layer is that a plurality of steel bands are arranged in order and are formed by connecting.
In preferred embodiment of the utility model, described screen is copper mesh woven mesh screen.
In preferred embodiment of the utility model, the material of described oversheath and inner sheath is polyvinyl chloride.
In preferred embodiment of the utility model, described insulating barrier is the fluoroplastic insulation layer.
The beneficial effects of the utility model are: the utility model signal transmission control cable can improve the shielding properties of cable, and sound construction is not fragile.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model signal transmission control cable one preferred embodiment;
The mark of each parts is as follows in the accompanying drawing: 1, oversheath, 2, the armouring tape layer, 3, inner sheath, 4, screen, 5, cable core, 6, polyester belt is wrapped, 7, the core group, 8, insulating barrier.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1, a kind of signal transmission control cable, comprise: oversheath 1, be provided with armouring tape layer 2 in the described oversheath 1, be provided with inner sheath 3 in the described armouring tape layer 2, be provided with screen 4 in the described inner sheath 3, be provided with a plurality of cable cores 5 in the described screen 4, be provided with polyester belt around 6 between described cable core 5 and the screen 4, described each cable core bag 4 vinculum core group 7 and insulating barrier 8.
In addition, described steel-tape armouring layer 2 is formed by connecting for a plurality of steel bands are arranged in order, and steel-tape armouring layer 2 protection cable can not destroyed, be corroded by chemical gas by the mechanical force in the external world.
In addition, described screen 4 is copper mesh woven mesh screen, and copper mesh woven mesh screen has good shielding properties.
In addition, the material of described oversheath 1 and inner sheath 3 is polyvinyl chloride, and polyvinyl chloride has mechanical strength, insulating properties, weatherability and anti-flammability preferably.
In addition, described insulating barrier 8 is the fluoroplastic insulation layer, fluoroplastics be part or all of hydrogen by the alkane polymer that fluorine replaces, have mechanical performance and insulation property preferably.
Be different from prior art, the utility model signal transmission control cable can improve the shielding properties of cable, and sound construction is not fragile.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
