Abstract
Disclosed is an anti-interference fireproof cable for a computer, comprising a plurality of wire cores, wherein each wire core is formed by intertwisting two sets of conductors wrapped by an insulating layer; each wire core is wound by a polyvinyl chloride taped covering 1; the taped covering 1 is coated by a copper strip coated sub-shielding layer; multiple wire cores coated by the sub-shielding layer are wrapped by a polyvinyl chloride taped covering 2; the polyvinyl chloride taped covering 2 is sequentially wrapped by a copper strip coated total shielding layer, a tin foil sleeve, and an outer sheath; and the polyvinyl chloride taped covering 2 is filled with flame retardation filler via squeezing. The anti-interference fireproof cable of the utility model adopts a design featuring double-layer insulating wrapping and double-layer shield combined with tin foil shield. Moreover, the filler is the glass fiber cord with great flame resistance performance. Therefore, the anti-interference fireproof cable of the utility model effectively improves the fireproof flame retardation performance and anti-interference performance of the computer cable. Moreover, the security and reliability of the cable are improved and the service lifetime of the cable is prolonged. The anti-interference fireproof cable of the utility model is particularly applicable to places with dense population and having high demands for device security and reliability.
Description
Technical field
The utility model relates to a kind of cable, is specially the anti-interference fireproof cable of a kind of computer.
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 the computer autoboot be might cause, the file of computer-internal or the hardware device of computer damaged.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 this utility model provides the anti-interference fireproof cable of a kind of computer, to solve prior art Computer fireproofing of cable poor performance, has the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
The anti-interference fireproof cable of a kind of computer, it is characterized in that: include several cores, every core consists of 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, described lapping layer one is coated with the wrapped sub-shield of copper strips, several cores that are surrounded with sub-shield are surrounded with polyvinyl chloride lapping layer two outward, the described lapping layer two outer wrapped total screen of copper strips, masking foil cover and the oversheaths of being coated with successively extrude in the described lapping layer two and are filled with fire-retardant filler.
The anti-interference fireproof cable of described a kind of computer is characterized in that: described fire-retardant filler is glass cord.
The anti-interference fireproof cable of described a kind of computer, it is characterized in that: described oversheath is made by the flame-proof polyvinyl chloride material.
The beneficial effects of the utility model are:
The utility model employing double hyer insulation is wrapped to add the design that masking foil shields with double layer screen, and be filled with the good glass cord of fire resistance, fire retardant performance and the interference free performance of computer cable have effectively been promoted, security reliability and the useful life of also having improved cable simultaneously, be particularly suitable for densely populated and higher to device security reliability requirement place.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the anti-interference fireproof cable of a kind of computer, include several cores 1, every core 1 consists of by two groups of conductor pair twists that are coated with insulating barrier are wrapped, the every core 1 outer polyvinyl chloride lapping layer 1 that is surrounded with, 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, the lapping layer 25 outer wrapped total screen 6 of copper strips, masking foil cover 7 and the oversheaths 8 of being coated with successively extrude in the lapping layer 5 two and are filled with fire-retardant filler 4.
Fire-retardant filler 4 is glass cord.Oversheath 8 is made by the flame-proof polyvinyl chloride material.
