Abstract

The utility model discloses an environmental-friendly, flame retardant, safe and reliable computer cable, belonging to the technical field of cables, which comprises a plurality of groups of sub-shielding cores, each group of which comprises at least one pair of insulated cores, and each insulated core comprises a conductor and an insulating layer coated outside the conductor; a flame retardant coating tape is coated outside the at least one pair of insulated cores, and a metal shielding layer is arranged outside the flame retardant coating tape, so as to form sub-shielding cores; an additional flame retardant coating tape is coated outside the plurality of groups of sub-shielding cores, and flame retardant fillers are filled among the plurality of groups of sub-shielding cores and the between the sub-shielding cores and the additional flame retardant coating tape; and a metal shielding layer is coated outside the additional flame retardant coating tape, a flame retardant inner sheath is coated outside the metal shielding layer, a metal armor layer is arranged outside the flame retardant inner sheath, and low-smoke non-halogen flame retardant outer sheath is coated outside the metal armor layer.

Description

Computer cable

Technical field

The utility model belongs to the cable technology field, relates in particular to a kind of computer cable.

Background technology

Existing computer cable does not have fire resistance, and the security reliability of cable is low under fire hazard environment, is not suitable for use in densely populated and higher to device security reliability requirement place.

The utility model content

Technical problem to be solved in the utility model provides a kind of environmental protection, and is fire-retardant, safe and reliable computer cable.

The utility model comprises multicomponent screen core, and every component screen core comprises at least one pair of insulated wire cores, and described each insulated wire cores comprises a conductor, at conductor outsourcing insulating layer coating; Wrapped fire-retardant twining package tape outside above-mentioned at least one pair of insulated wire cores, fire-retardant twining package tape is provided with metal screen layer outward, thereby forms the split screen core; The outer wrapped other fire-retardant twining package tape of above-mentioned multicomponent screen core, and at the fire-retardant filler of filling between the described multicomponent screen core and between split screen core and the other fire-retardant twining package tape; Above-mentioned other fire-retardant twining package tape coats metal screen layer outward, the fire-retardant inner sheath of metal screen layer outer wrapping, and fire-retardant inner sheath is provided with the metal armouring layer outward, and described metal armouring layer coats the low-smoke non-halogen flame-retardant oversheath outward.

Compare with existing computer cable, because oversheath adopts halogen-free low-smoke flame retardant material to make in the utility model, and inner sheath, band all has fire resistance, in cable, fill fire-retardant filler simultaneously, so the utlity model has excellent flame-retardant, the smog that has produced because of burning when having checked the control circuit fire incident effectively and the effusion of toxic and harmful, the security reliability and the useful life of cable have been improved, be especially suitable for use as densely populated and higher place, for example the station to the device security reliability requirement, hospital, subway, dwelling house and office building etc.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

Embodiment

As shown in Figure 1, comprise four components screen core 1 in the present embodiment, every component screen core 1 comprises a pair of insulated wire cores 1-1, and described each insulated wire cores 1-1 comprises a conductor 1-1-1, coats crosslinked polyetylene insulated layer 1-1-2 outside conductor 1-1-1.Wrapped glass fiber flame retardant twining package tape 1-2 outside above-mentioned a pair of insulated wire cores 1-1, glass fiber flame retardant twining package tape 1-2 is provided with copper wire woven shield 1-3 outward, thereby forms split screen core 1.Every component screen core 1 in the present embodiment only comprises a pair of insulated wire cores 1-1, preferably, also can comprise many to insulated wire cores 1-1.

Four components screen core, 1 outer wrapped glass fiber flame retardant twining package tape 2, and the fire-retardant filler 3 of filled glass fiber between described four components screen core 1 and between split screen core 1 and the glass fiber flame retardant twining package tape 2.

The above-mentioned glass fiber flame retardant twining package tape 2 outer copper wire woven shields 4 that coat, the fire-retardant inner sheath 5 of copper wire woven shield 4 outer wrapping, the fire-retardant inner sheath 5 outer copper strips armours 6 that are provided with, the described copper strips armour 6 outer low-smoke non-halogen flame-retardant oversheaths 7 that coat.

Claims
