Fireproof computer cable

Technical Field

The invention relates to the field of fireproof cables, in particular to a fireproof computer cable.

Background

To ensure data security, it is desirable to have enough time to back-pack all data after a fire before the entire network fails and move them to a safe place to minimize the possibility of data loss. The aim of the fireproof cable is that the cable can still keep the circuit smooth in a fire scene, so that power supply and information can still be normally transmitted. The existing fireproof cables in the market are all formed by sleeving one layer of fireproof material and another layer of fireproof layer outside a cable core, so that the fireproof cables are not ignited in a fire disaster, and the fireproof purpose is achieved. To this end, we propose a fire-resistant computer cable.

In order to achieve the purpose, the invention adopts the following technical scheme that the fireproof computer cable comprises a cable inner core, wherein the cable inner core is made of high-purity brass, the cable inner core is of a cylindrical structure, a rubber insulating inner sleeve is sleeved at the excircle of the cable inner core, a keel is sleeved at the excircle of the rubber insulating inner sleeve and is of a cylindrical structure, keel supports are fixedly installed at the excircle of the keel, the keel supports are multiple groups, four groups of keel supports are arranged on the same horizontal plane, a rubber sleeve is fixedly installed on one side of each keel support, which is far away from the center of the interior of the keel, a fireproof air layer is arranged in the area between the rubber sleeve and the rubber insulating inner sleeve, and carbon dioxide gas is filled in the fireproof air layer.

Preferably, an anticorrosion shell is arranged at the excircle of the rubber sleeve, sealing layers are arranged at two ends of the anticorrosion shell, and the sealing layers are of disc-shaped structures.

Preferably, a hole is formed in the middle of the sealing layer, the inner diameter of the round hole in the middle of the sealing layer is equal to the outer diameter of the rubber insulating inner sleeve, one side of each of the two groups of sealing layers, which is close to the inner center of the cable inner core, is fixedly and hermetically connected with the anti-corrosion shell, and one side of each of the two groups of sealing layers, which is close to the inner center of the cable inner core, is fixedly and hermetically connected with both ends of the keel and the rubber.

Preferably, the rubber insulating inner sleeve penetrates through the sealing layer through a round hole formed in the surface of the sealing layer and extends to the outer side of the sealing layer.

Advantageous effects

The invention provides a fireproof computer cable. The method has the following beneficial effects:

(1) this fire prevention computer cable, when the outside conflagration breaing out, the back is burnt out with outer anti corrosion housing of cable and rubber sleeve to fire, fills the outside that the carbon dioxide gas between rubber sleeve and rubber insulation endotheca can stretch the cable, because the density of carbon dioxide gas is greater than the density of air, so carbon dioxide gas can stretch and can not dissipate in the short time around the cable for the cable can not continue to receive the erosion of conflagration, can keep the stable use of a considerable period.

(2) This fire prevention computer cable sets up the flame retardant coating through the inside at computer cable, uses the inside carbon dioxide gas who fills in fire prevention gas layer to prevent fires, has abandoned traditional fire prevention cable to cup joint the fire resistive material of one deck again in the outside of cable core, has reached reduce cost's effect.

Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

Example (b): a fireproof computer cable is shown in figures 1-3 and comprises a cable inner core 1, wherein the cable inner core 1 is made of high-purity brass, the cable inner core 1 is of a cylindrical structure, a rubber insulation inner sleeve 2 is sleeved at the outer circle of the cable inner core 1, the rubber insulation inner sleeve 2 is made of insulation rubber, the rubber insulation inner sleeve 2 is of a cylindrical structure, a keel 3 is sleeved at the outer circle of the rubber insulation inner sleeve 2, the keel 3 is of a cylindrical structure, the keel 3 is made of high-strength metal, four groups of keel supports 31 are fixedly installed at the outer circle of the keel 3, the four groups of keel supports 31 at the outer circle of the keel 3 are located on the same horizontal plane, the keel supports 31 are made of plastic, a rubber sleeve 4 is fixedly installed at one side, away from the center inside the keel 3, of the keel supports 31, and the rubber sleeve 4 is made of rubber, the region between rubber sleeve 4 and the rubber insulation endotheca 2 is provided with fire prevention gas layer 5, fire prevention gas layer 5 separates fossil fragments 3 and rubber sleeve 4 through the fossil fragments support 31 that sets up between fossil fragments 3 and rubber sleeve 4, the inside packing of fire prevention gas layer 5 has carbon dioxide gas.

The outer circle of the rubber sleeve 4 is provided with an anti-corrosion shell 6, the anti-corrosion shell 6 is a special anti-corrosion shell for the cable, the anti-corrosion shell 6 can prevent external corrosive substances from corroding the structure inside the cable, the anti-corrosion shell 6 is of an existing structure and is not described herein any more, sealing layers 7 are arranged at two ends of the anti-corrosion shell 6, each sealing layer 7 is of a disc-shaped structure, each sealing layer 7 is made of rubber, a hole is formed in the middle of each sealing layer 7, the inner diameter of a round hole in the middle of each sealing layer 7 is equal to the outer diameter of the rubber insulating inner sleeve 2, one side of each sealing layer 7, which is close to the center inside the cable inner core 1, is fixedly and hermetically connected with the anti-corrosion shell 6, and one side of each sealing layer 7, which is close to the center inside the cable inner core, the rubber insulating inner sleeve 2 penetrates through the sealing layer 7 through a round hole formed in the surface of the sealing layer 7 and extends to the outer side of the sealing layer 7.

The working principle of the invention is as follows:

when a fire disaster occurs outside, after the anti-corrosion shell 6 and the rubber sleeve 4 on the outer layer of the cable are burnt by the fire, the carbon dioxide gas filled between the rubber sleeve 4 and the rubber insulating inner sleeve 2 can spread to the outer side of the cable, and because the density of the carbon dioxide gas is greater than that of air, the carbon dioxide gas can spread around the cable and cannot be dissipated in a short time, so that the cable cannot be continuously corroded by the fire, and the stable use of the cable for a long time can be kept.
