Abstract

A novel photoelectric composite cable is a composite type cable suitable for transmitting an optical signal and a civil low-voltage electric power to block residents and rural residents at the same time. The novel photoelectric composite cable is characterized in that: two PBT (Polybutylene Terephthalate) loose tubes and two insulated copper wires are arranged into a cross shape, one metal reinforcement is added in a gap at an outer side of the loose tubes and the insulated copper wires, then an SZ-intertwist is performed to form a cable core; wherein the FBT loose tube is provided with optical fiber paste and a plurality of optical fibers therein; insulation type water-blocking cable paste is filled around the cable core and in gaps thereof; and a periphery of an outer side of the cable core is longitudinally wrapped by a metal composite belt, a polyethylene sheath is extruded at a periphery of an outer side of the metal composite belt to form the cable finally. The novel photoelectric composite cable realigns number and locations of materials such as the PBT loose tubes, the insulated copper wires, the metal reinforcement and so on, so as to reduce using kind and number of the materials, reduce production cost, and reduce an external diameter and the weight of the cable, thereby benefiting construction and laying.

Description

A kind of novel photoelectric composite rope

Technical field

The utility model relates to a kind of compound cable that is applicable to block and urban residents user's while transmitting optical signal and civilian low-voltage power.

Background technology

Optoelectronic composite cable in the market is according to the stranding pattern of common layer-stranding cable two insulated copper cash and some PBT pine sleeve pipes and presumable gasket for packing SZ form to be stranded in around the metal reinforcement, and around vertically wrap polyester belt, metal compound belt, and then extrude pe sheath; This kind optoelectronic composite cable; Because according to common layer-stranding cable pattern stranding, material therefor kind, quantity are more, and production cost height and cable external diameter are bigger than normal; Weight is big, is unfavorable for laying of cable.

Summary of the invention

Various in order to overcome existing optoelectronic composite cable production with material; Cost height and cable be big and heavy to be unfavorable for the deficiency of laying; The utility model provides a kind of novel photoelectric composite rope; This kind optoelectronic composite cable can reduce material category and quantity, and the cable external diameter is reduced, and provides cost savings and can be beneficial to engineering to lay.

The scheme that the utility model solves its technical problem is: 2 insulated copper cash and 2 PBT pine sleeve arrangement are become the sphere of movements for the elephants pattern; Side clearance adds 1 metal reinforcement outside it; And carry out the stranded composition cable core of SZ; Secondly around cable core and the gap fill the insulated type cable cream that blocks water, metal compound belt vertically is coated on around the cable core then, last pe sheath then extrudes around the metal compound belt outside.Wherein the copper cash in the insulated copper wire is single filled circles copper cash or annealed copper wire, and the insulating sleeve material of insulated copper wire adopts polyethylene or polyvinyl chloride, is provided with optical fiber cream and some optical fiber in the PBT pine sleeve pipe; This kind solution is reset arrangement with quantity, the position of metal reinforcement, insulated copper wire, PBT pine sleeve pipe; Do not adopt gasket for packing, and replace the insulating effect of polyester belt, so just make the use kind and the quantity reduction of material with the insulated type cable cream that blocks water; Production cost reduces; Also impel final cable external diameter to reduce, weight saving has made things convenient for engineering to lay.

The beneficial effect of the utility model is, reduced the use kind and the quantity of producing material, reduced production cost, and final cable external diameter reduces, and weight saving has made things convenient for engineering to lay.

Description of drawings

Below in conjunction with Figure of description the utility model is further specified, Fig. 1 is the utility model cross sectional representation, 1. optical fiber among the figure, 2. optical fiber cream; 3.PBT loose sleeve pipe, 4. block water cable cream, 5. insulated copper wire of insulated type; 6. metal compound belt, 7. pe sheath, 8. metal reinforcement.

Embodiment

At optical fiber described in Fig. 1 (1), optical fiber cream (2), place PBT pine sleeve pipe (3); Said insulated copper wire (5), PBT pine sleeve pipe (3) are arranged in the sphere of movements for the elephants pattern; And side clearance adds said metal reinforcement (8) composition cable core outside it; The said insulated type cable cream (4) that blocks water is filled in around the cable core and the gap, and said metal compound belt (6) is coated on around the cable core, and said pe sheath (7) extrudes in metal compound belt (6) all around.

During production; At first with some optical fiber 1 at the core rod that gets into extruder die on the secondary coating production line on the secondary coating production line with the drawing tension unwrapping wire of certain speed, in core rod, have spindle that optical fiber cream 2 is sprayed on around the optical fiber 1, subsequently at the mould outlet place; Plastic extruding machine is extruded the PBT material of molten condition around optical fiber 1 and optical fiber cream 2; Along with tractive effort fast moves forward, the PBT of molten condition material is crystallisation by cooling sclerosis fast in hot water storgae and cold rinse bank, forms the loose sleeve pipe 3 of PBT.

Secondly; With copper cash at the core rod that gets into extruder die on the secondary coating production line on the secondary coating production line with the drawing tension unwrapping wire of certain speed; At the mould outlet place, plastic extruding machine is extruded the polyethylene material or the polyvinyl chloride material of molten condition around copper cash subsequently, along with tractive effort fast moves forward; The polyethylene material of molten condition or polyvinyl chloride material form insulated copper wire 5 in hot water storgae and the quick crystallisation by cooling sclerosis of cold rinse bank.

The 3rd, 2 PBT pine sleeve pipe, 3,2 insulated copper cash 5 are arranged in the sphere of movements for the elephants pattern, outer side clearance adds 1 metal reinforcement 8 and on the SZ production line, is twisted into cable core with certain twisting pitch, and around cable core and the gap fill the insulated type cable cream 4 that blocks water.

The 4th; With having filled the block water cable core of cable cream 4 of insulated type; On the sheath production line,, before getting into the extruder die core rod, around cable core, vertically coat layer of metal composite band 6 with certain laying tension traction unwrapping wire; Pass again subsequently the extruder die core rod to mould mouth place by plastic extruding machine with the pe sheath 7 of molten condition extrude in around, the preforming cable is and then by the final stranding of cooling in quick traction to the cold rinse bank.

This kind cable is arranged quantity, the position of metal reinforcement, insulated copper wire, PBT pine sleeve pipe again; Do not adopt gasket for packing, and replace the insulating effect of polyester belt, so just make the use kind and the quantity reduction of material with the insulated type cable cream that blocks water; Production cost reduces; Also impel final cable external diameter to reduce, weight saving has made things convenient for engineering to lay.

Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
