Ratproof data cable

Abstract

The invention discloses a ratproof data cable. The ratproof data cable comprises a cable inner core, a fireproof layer and an insulating layer which are arranged from inside to outside in sequence, wherein the cable inner core comprises a foaming framework and a conductor core group; the foaming framework comprises four limiting convex strips; the conductor core group is mounted in a mounting cavity; the conductor core group comprises a pair of wires which are arranged side by side; the exterior of the pair of wires is coated with an insulating layer; the outline of the cross section of the insulating layer adopts a regular hexagon shape; the edge of the insulating layer is sprayed with a ratproof coating film; the formula of the ratproof coating film comprises capsicin; adhesion layers are arranged on all the six outer side faces of the insulating layer. By virtue of the cable inner core, the fireproof layer, the regular hexagonal insulating layer, and the ratproof coating film which is arranged on the edge of the insulating layer, the ratproof data cable has a good ratproof effect, low dosage of rodenticide, and low pollution to the environment; and meanwhile, the shortcomings of relatively high weight and high cost of the existing data cable which is armoured with metal on the surface for preventing rodents from biting the cable are solved.

Description

technical field [0001] The invention relates to the field of cable production, in particular to a mouse-proof data cable. Background technique [0002] With the rapid development of optical communication technology, optical cables have been widely used in the backbone network and inter-office trunk lines of wired communication networks, and it has become an inevitable trend for optical fibers to enter the access network. However, the cost of laying optical cables is too high, and the cost of joints and terminal optical-electrical conversion is expensive. Therefore, for a long time before the popularization of optical fiber, the subscriber lines of the access network will still be dominated by metal cables. As a kind of metal cable, data cable is currently an ideal transmission medium for broadband access network. It has the advantages of low manufacturing cost, simple structure, good expandability, and easy network upgrade. It is mainly used for integrated wiring of building...

Problems solved by technology

[0004] The invention provides a data cable, so that the existing data cables using metal armor have large weight, high cost, and the defects of easy corrosion and failure can be solved.

And the hexagonal rodent-proof data cable, it is more convenient to stack multiple data cables, there is no gap, which reduces the situation of water and dust accumulation in the actual placement process, and the adhesive layer is used on the outer side of the insulating layer to reduce the use of Bundled plastic wires are more convenient to stack and easy to operate. The invention has a simple structure and solves the defects of the existing data cables that are covered with metal armor on the surface to prevent rodents from gnawing on them, and their weight is high and the cost is high.
