Abstract
The utility model discloses a fireproof shielded cable for a computer. The fireproof shielded cable comprises a plurality of cores, two groups of conductors covered with insulating layers are twisted in pair and lapped to form each core, a first polyvinyl chloride lapping layer is lapped on the outside of each core, a copper strip lapping branched shielding layer covers each first lapping layer, a second polyvinyl chloride lapping layer is lapped on outsides of the cores lapped with the branched shielding layers, a copper strip lapping main shielding layer, an inner sheath, an armor layer and an outer sheath sequentially cover the outside of the second lapping layer, and a flame-retardant filling is filled in the second lapping layer in an extruded manner. The double-layered insulating lapping and double-layered shielding design is adopted, a glass fiber rope with excellent flame-retardant performance is filled in the second lapping layer, so that fireproof and flame-retardant performance and interference resistance of the cable for the computer are effectively enhanced, safety and reliability of the cable are also improved, the service life of the cable is prolonged, and the fireproof shielded cable is particularly suitable for places with dense population and high requirements on safety and reliability of equipment.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of computer and uses the fire-proof shield cable.
Background technology
The employed cable of computer is higher than general equipment to the stability requirement of electric current; If electric current is unstable; Computer might produce electricity shortage; Might burn out electric capacity or power supply, also might cause computer to restart automatically, damage the file of computer-internal or the hardware device of computer.The computer cable that uses at present scarcely has fire resistance, and fire protecting performance is poor, interference free performance is not strong, and the security reliability of cable is low under fire hazard environment, and the proof voltage ability is not good yet, brings certain hidden danger for many work.
The utility model content
The purpose of the utility model provides a kind of computer and uses the fire-proof shield cable, and is poor with the fire protecting performance that solves computer cable in the prior art, has the problem of potential safety hazard.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of computer is used the fire-proof shield cable; It is characterized in that: include several cores; Every core constitutes by two groups of conductor pair twists that are coated with insulating barrier are wrapped; Every core is surrounded with polyvinyl chloride lapping layer one outward, and said lapping layer one is coated with the wrapped sub-shield of copper strips, and several cores that are surrounded with sub-shield are surrounded with polyvinyl chloride lapping layer two outward; Be coated with the wrapped total screen of copper strips, inner sheath, armour and oversheath successively outside the said lapping layer two, extrude in the said lapping layer two and be filled with fire-retardant filler.
Described a kind of computer is used the fire-proof shield cable, it is characterized in that: said fire-retardant filler is a glass cord.
Described a kind of computer is used the fire-proof shield cable, it is characterized in that: said oversheath is processed by the flame-proof polyvinyl chloride material.
The beneficial effect of the utility model is:
The utility model adopts the wrapped design with double layer screen of double hyer insulation; And be filled with the good glass cord of fire resistance; The fire retardant performance and the interference free performance of computer cable have been promoted effectively; The security reliability and the useful life of also having improved cable simultaneously, be particularly suitable for densely populated and higher place to the device security reliability requirement.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model includes several cores 1; Every core 1 constitutes by two groups of conductor pair twists that are coated with insulating barrier are wrapped; Be surrounded with polyvinyl chloride lapping layer 1 outside the every core 1, lapping layer 1 is coated with the wrapped sub-shield 3 of copper strips, several core 1 outer polyvinyl chloride lapping layers 25 that are surrounded with that are surrounded with sub-shield 3; Lapping layer 25 is outer to be coated with the wrapped total screen of copper strips 6, inner sheath 7, armour 8 and oversheath 9 successively, extrudes in the lapping layer 5 two and is filled with fire-retardant filler 4.
Fire-retardant filler 4 is a glass cord.Oversheath 9 is processed by the flame-proof polyvinyl chloride material.
Claims (3)
1. a computer is used the fire-proof shield cable; It is characterized in that: include several cores; Every core constitutes by two groups of conductor pair twists that are coated with insulating barrier are wrapped; Every core is surrounded with polyvinyl chloride lapping layer one outward, and said lapping layer one is coated with the wrapped sub-shield of copper strips, and several cores that are surrounded with sub-shield are surrounded with polyvinyl chloride lapping layer two outward; Be coated with the wrapped total screen of copper strips, inner sheath, armour and oversheath successively outside the said lapping layer two, extrude in the said lapping layer two and be filled with fire-retardant filler.
