Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, a multifunctional optical cable includes: the loose tube 110, the reinforcing layer 120 and the outer sheath 130 are arranged from inside to outside in sequence; an ultraviolet curing resin 111 and a plurality of optical fibers 112 fixed in the ultraviolet curing resin at intervals are arranged in the loose tube; eight wire releasing grooves 113 are uniformly arranged on the outer edge of the loose tube in an annular mode; four positive leads 114 and four negative leads 115 are alternately arranged in the eight discharge slots; the outer sheath is made of polyethylene material; the reinforcing layer is made of glass yarn material.

The utility model has the advantages that:

by arranging the paying-off grooves on the loose tube to place the power cables, optical signals and power transmission can be synchronously performed. Compared with a single wire, the power cable (the four positive wires form the positive power cable, and the four negative wires form the negative power cable) is split into four wires (both the positive power cable and the negative power cable) which are uniformly arranged in a 90-degree circumference, so that the inductance of the power cable is reduced, the capacitance of the power cable is increased, the wave impedance of the power cable to alternating current is reduced, and the power transmission capacity of the multifunctional optical cable is improved. The four positive wires and the four negative wires are arranged in the six wire releasing grooves, so that the wires are not easy to loosen. The ultraviolet curing resin is adopted to replace filling fiber paste, and when the construction of the optical cable or the environment changes, the position of the optical fiber is not easy to change.

In one of the embodiments, the loose tube is made of PBT plastic (polybutylene terephthalate).

In one embodiment, the optical fiber is a colored optical fiber. The optical fiber sequence can be identified when the optical fiber is spliced, terminated and used.

In one embodiment, the number of optical fibers is two.

It is understood that the positive conductor includes a copper core wire and an insulating sheath from the inside out. The negative electrode lead comprises a copper core wire and an insulating sheath from inside to outside.

In one embodiment, a plurality of reinforcing steel wires 131 are disposed within the outer sheath.

In one embodiment, the number of the reinforcing steel wires is four.

The outer sheath made of polyethylene material is provided with the reinforcing steel wires, so that the strength of the outer sheath is further enhanced.

In one embodiment, the wire arrangement groove comprises a bottom surface and a side surface, and the included angle between the side surface and the bottom surface is 120-140 degrees. In this way, the wire is easily snapped into the wire trap.

In one embodiment, the glass yarns are water-blocking glass yarns.

The reinforcing layer is made of glass yarns, so that the optical cable can prevent small rodents from damaging the optical cable when in use, and is suitable for places with slight rats. The reinforcing layer can also be made of water-blocking glass yarns, so that the glass yarns can play a role and can further play a waterproof role. Meanwhile, the reinforcing layer arranged inside the optical cable can also enhance the hardness of the whole structure of the optical cable and increase the pressure resistance of the optical cable.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
