Problems solved by technology

[0010] Most of the above studies are carried out from the perspective of using hard sheath or hard armor layer. The hard sheath is mainly made of nylon materials and high-density polyethylene. Nylon materials are commonly used nylon 6, nylon 12, Nylon 66 series are mainly imported from abroad, and the price is about 600 yuan / kg, so it is very expensive; in addition, nylon has excellent acid and alkali resistance, so it is difficult to decompose itself, and a large amount of nylon is used for the sustainable development of the environment. In addition, nylon has a very narrow temperature processing range and cleanliness requirements. Usually, when making nylon cables, the melted nylon has extremely low viscosity characteristics, so even in the case of rapid cooling, the nylon layer can be processed at one time. It can only be under 1mm thickness, so it is extremely inconvenient to process
Generally speaking, the armor layer is steel strip or aluminum strip or steel wire. Steel strip and steel wire are easy to rust over time. Of course, chrome-plated steel strip or steel wire can also be used. Since chromium is a poisonous and harmful substance, it can In the daily management of human beings, cables will become toxic and harmful substances, so they are not environmentally friendly; the strength of aluminum strips is also very limited, and cables are generally only used as shielding or moisture barriers; for this reason, the industry expects more environmentally friendly, manufacturing more Convenient, less expensive rodent and termite control

Embodiment 1

[0032] please see figure 1 and figure 2, a rodent-proof and termite-proof optical cable, which includes a plurality of optical cable units 1, an inner sheath 2 covering a plurality of cable units, and an outer sheath 4 outside the inner sheath, characterized in that the inner sheath and There is also a rodent-proof and termite-proof layer 3 between the outer sheaths, and the rodent-proof and termite-proof layer 3 is composed of a sealed bag-like body 31 and a rat-proof and termite-proof part 33 located in the bag-like body; there are multiple bag-like bodies, Adjacent bags are separated by partitions 32; the thickness of the rodent and termite-proof layer is 0.20 mm to 0.80 mm; the rodent and termite-proof components are calcium carbonate, which exists in the bag-like bodies in the form of powder , the upper surface 311, the left surface 312, the lower surface 313, the right surface 314, and the front and rear surfaces of the bag-shaped body are gas and liquid-tight; the bag...

Embodiment 2

[0035] please see image 3 , and refer to figure 2 , a rodent-proof and termite-proof optical cable, basically the same as the implementation example 1, the difference is that: the optical cable unit 1 is composed of an optical fiber 11 located inside and a sleeve 12 located outside the optical fiber; the optical cable unit is twisted around the central strength member .

[0036] Of course, among the five cable units in the figure, some of them may be filled ropes, and the filled ropes are solid or hollow structures made of polyethylene or polypropylene.

Embodiment 3

[0038] please see Figure 4 , and refer to figure 2 , a rodent-proof and termite-proof optical cable, which is basically the same as in Example 2, except that: there is a cushion layer 5 between the rodent-proof and termite-proof layer and the inner sheath; Wrapped outside the inner sheath, there is a partial overlap between the rear helix and the front helix when the helix is ​​wrapped, and there is an overlapping overlap when the longitudinal wrap is used; the material of the cushion layer is nylon 6 or nylon 12 or nylon 66 .

[0039] Of course, the rodent-proof and termite-proof optical cable described in any of the above implementation examples includes a plurality of optical cable units 1, an inner sheath 2 covering the plurality of optical cable units, and an outer sheath outside the inner sheath 4. It is characterized in that there is a rodent-proof and termite-proof layer 3 between the inner protective layer and the outer protective layer. The rodent-proof and termi...

Abstract

The invention belongs to the technical field of cables and electric power, and relates to a rat-proof and termite-proof optical cable. The rat-proof and termite-proof optical cable comprises a plurality of optical cable units (1), an inner protection layer (2) covering the optical cable units, and an outer protection layer (4) located outside the inner protection layer. The rat-proof and termite-proof optical cable is characterized in that a rat-proof and termite-proof layer (3) is further disposed between the inner protection layer and the outer protection layer, and the rat-proof and termite-proof layer (3) is composed of sealed bag-like bodies (31) and rat-proof and termite-proof parts (33) located in the bag-like bodies; a cushion layer (5) is further disposed between the rat-proof and termite-proof layer and the inner protection layer; the bag-like bodies spirally or vertically cover the inner protection layer, and the material of the cushion layer is nylon 6, nylon 12 or nylon 66; each optical cable unit (1) is composed of optical fibers (11) located in the corresponding optical cable unit and a bushing (12) located outside the optical fibers; and the optical cable units are intertwisted around a center reinforcement member. The rat-proof and termite-proof optical cable has the main advantages of the good rat-proof and termite-proof effect, low optical cable cost, easy production and the high finished product rate in optical cable production; and the optical cable is relative environmental-friendly.

Description

[0001] The present invention is a divisional application for an invention patent named: A rodent-proof and termite-proof cable, with the filing date: May 26, 2014, and the application number: 201410224452.8. technical field [0002] The invention belongs to the technical field of cables and electric power, and in particular relates to a rodent-proof and termite-proof optical cable. Background technique [0003] As one of the pests, rats and ants often damage cables and affect the transmission of electricity and signals. In the cold season, rats are relatively harmful to cables. Rats are mainly mice and squirrels, which have sharp teeth. , can bite through the sheath of the cable or even the protective layer of steel and aluminum strips, directly affecting the performance of the cable, and at the same time, it also causes a great potential safety hazard. Rat groups often use the success of a certain rat as an example to carry out collective Follow suit, grind teeth and eat; i...
