Ratproof data cable

Abstract

The invention discloses a ratproof data cable which comprises a cable inner core, a refractory layer and an insulation layer, wherein the cable inner core, the refractory layer and the insulation layer are sequentially arranged from inside to outside. The cable inner core comprises a foaming skeleton and a conductor core group. The foaming skeleton comprises four limiting raised lines. The conductor core group is arranged in a mounting cavity. The conductor core group comprises a pair of wires arranged in parallel. A pair of wires is covered by the insulation layer. The outer contour of the cross section of the insulation layer is a regular hexagon. The edge of the insulation layer is sprayed by a ratproof coating. Capsaicin is contained in the formula of the ratproof coating. Adhesive layers are arranged on six outer sides of the insulation layer. According to the invention, the cable inner core, the refractory layer and the insulation layer shaped like the regular hexagon are arranged; the edge of the insulation layer is coated by the ratproof coating; the ratproof effect is great; less rodenticide is used, which reduces environmental pollution; and the defects of heavy weight and expensive cost of the existing data cable whose surface is coated with a metal armor to prevent biting of rodents are solved.

Description

[0001] This application is a divisional application with an application date of May 26, 2016, an application number of 201610361914.X, and an invention title of "anti-rat data cable". technical field [0002] The invention relates to the field of cable production, in particular to a mouse-proof data cable. Background technique [0003] 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 broa...

Problems solved by technology

[0005] 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.
