In the figure: 1. an outer sheath; 2. a copper wire; 3. an insulating sleeve; 4. a sheath; 5. water-blocking yarn I; 6. a second water-blocking yarn; 7. tensile plastic; 8. and tightly sleeving the optical fiber.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a novel mixed cable structure of photoelectricity, includes oversheath and copper core insulated wire and the optical fiber unit of setting in the oversheath, copper core insulated wire and optical fiber unit all are provided with 2, and all copper core insulated wire and optical fiber unit transposition set up in the oversheath, and set up for interval in proper order between optical fiber unit and the copper core insulated wire, be provided with the yarn that blocks water on the inside wall of oversheath.

The copper core insulated wire is an insulated sleeve tightly sleeved outside the internal copper conductor.

The oversheath is provided with 4 yarn one that blocks water in, 4 yarn one that blocks water for 2 settings of each side about.

The optical fiber unit comprises a sheath, filler and a tight-buffered optical fiber, the sheath is arranged on the outer side of the tight-buffered optical fiber, and the filler is filled between the sheath and the tight-buffered optical fiber.

And a filler is arranged in the gap between the outer sheath and the copper core insulated wire and between the outer sheath and the optical fiber unit.

The filler and the filling material are both tensile plastics.

And 2 water-blocking yarns II are arranged on the inner wall of the sheath.

According to the technical scheme, the optical fiber is preheated and coated with the tight-buffered layer in the production process, then the reinforcing member and the water-blocking yarn are coated outside the tight-buffered optical fiber, the paying-off tension and the taking-up tension are stable in the production process of the optical fiber subunit, and the performance of the optical fiber is guaranteed to be qualified; the copper core conductor is preheated and coated with the insulating layer, so that the adhesive force of the insulating layer is improved. The sheath stripping force test is carried out before production, the sheath is required to be stripped easily, and the insulated core wires are required to be arranged separately and cannot be contacted.

The optical fiber subunits and the copper core insulated wires are arranged at intervals and are stranded, and the stranding pitch and the tightness meet the process requirements; after the stranding is finished, a layer of reinforcing member (aramid yarn) and a sheath layer are uniformly coated, the sheath is round in appearance, and the printed characters are attractive.

In the photoelectric mixed cable structure, the optical fiber subunits and the cable core wires are stranded together, and the stranded core wires enable the cable to have good flexibility and are convenient to lay and install; meanwhile, the reinforcing members are arranged in the optical fiber subunits and outside the cabling structure, the overall tensile capacity of the cable is increased, and the transmission performance of the optical fiber is greatly influenced by the fact that the optical fiber is affected by moisture, so that the water blocking yarns are arranged outside the cabling structure and in the optical fiber subunits, and the cable has good water blocking performance.

1. The cable can transmit electric signals and optical signals, and the use function of the cable is increased;

2. the space and the cost occupied by simultaneously laying the cable and the optical cable are saved;

3. the whole flexibility is good, the flexible laying can be realized, and the construction efficiency is improved;

4. has good transmission performance, tensile strength and water resistance.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
