Description

Technical Field

[0001] The invention belongs to the technical field of power communication and cables, and in particular relates to a butterfly-shaped lead-in optical cable for power communication. Background Art

[0002] CN209784614U discloses a multi-purpose duct butterfly cable, which has a butterfly optical cable located at the center of the cable, characterized in that it also has two tight-fitting optical units located on both sides of the butterfly optical cable, a protective layer wrapped outside the butterfly optical cable and the tight-fitting optical unit, a reinforcement layer located outside the protective layer, and an outer sheath extruded outside the reinforcement layer; the tight-fitting optical unit is composed of a tight-fitting layer in which an optical fiber is wrapped outside the optical fiber. It has the following main beneficial effects: simple structure, easy to manufacture, photoelectric simultaneous transmission, good tensile performance, and the tight-fitting optical fiber has an invisible effect.

[0003] CN205427277U discloses a duct butterfly optical cable, including colored optical fiber, glass fiber reinforced plastic round rod FRP, PE sheath, the center of which is the colored optical fiber, glass fiber reinforced plastic round rod FRP is provided on both sides of the colored optical fiber, the low smoke halogen-free sheath is outside the colored optical fiber and the glass fiber reinforced plastic round rod FRP, the two sides of the low smoke halogen-free sheath are semicircular, and it is concentric with the glass fiber reinforced plastic round rod FRP, there is a V-shaped groove in the middle of the plane on both sides of the low smoke halogen-free sheath, there is an aramid yarn reinforcement on the V-shaped groove, there is a water blocking tape outside the low smoke halogen-free sheath and the aramid yarn reinforcement, there is a moisture-proof aluminum tape outside the water blocking tape, and there is a PE sheath outside the moisture-proof aluminum tape, forming a duct butterfly optical cable. It has a reasonable design, a simple and compact structure, a light weight, is easy to use and maintain, has good mechanical properties, and is suitable for outdoor laying such as shafts, cable troughs, and pipelines.

[0004] CN204178023U discloses a butterfly-shaped pipeline optical cable. It includes a water-blocking tape, a butterfly-shaped flame-retardant sheath and an optical fiber. The optical fiber is arranged at the center of the butterfly-shaped flame-retardant sheath. The water-blocking tape wraps the butterfly-shaped flame-retardant sheath. Two reinforcing members are symmetrically arranged in the butterfly-shaped flame-retardant sheath along the long axis direction of the butterfly-shaped flame-retardant sheath with the optical fiber as the center. Two relative V-shaped grooves are arranged on the two side surfaces of the butterfly-shaped flame-retardant sheath along the short axis direction of the butterfly-shaped flame-retardant sheath. It also includes an outer sheath, a steel belt and an inner sheath arranged in sequence from the outside to the inside. The inner sheath covers the water-blocking tape. An aramid reinforcing member is respectively arranged at the V-shaped grooves on both sides. The butterfly-shaped pipeline optical cable can effectively prevent rats and has good compression resistance, tensile resistance and water-blocking performance. It is suitable for relatively harsh occasions such as pipeline environments.

[0005] The above optical cables all have the following defects: the strength members are located on both sides of the butterfly-shaped lead-in optical cable, which does not provide sufficient tensile protection for the optical cable, and it is easy to slide due to its large space; and because the structure is too loose, the product is extremely not round. The above optical cables produced by the company where the inventor worked a few years ago were complained and returned many times due to the above reasons. Moreover, there is only one butterfly-shaped lead-in optical cable unit in the above product, so the communication density is extremely low, and the cost is extremely high when there are multiple channels.

[0006] CN206906647U discloses a unit-type indoor optical cable, which has a central reinforcement member, a butterfly unit and a fixed binding wire. A plurality of butterfly units are twisted around the central reinforcement member and fixed with a fixed binding wire to form an optical cable. An outer sheath can be arranged outside the fixed binding wire according to user needs. The present invention has a simple structure, and the number of cores can be designed according to the needs of different construction environments, and the wiring can be constructed from the central end to the user at one time. The reinforcement layer and the outer sheath can be stripped within a suitable section length range according to the needs of each user or each floor, and one or more butterfly units are branched out separately. The rest of the cable core continues to be laid to other users or floors, and no optical fiber connector is required in the middle, which effectively reduces the construction cost, reduces line loss, and improves the transmission quality. The outer sheath is arranged outside the fixed binding wire, which can also make it more convenient to lay the optical cable in the pipeline, and the outer sheath protects the internal components of the optical cable. Although it has expanded communication capacity, it has a complex structure. After stripping, the unnecessary parts in the single layer are also taken out, which brings inconvenience to the user.
