Abstract
The optical units at two ends of the cable are respectively provided with an extension section which is longer than the power unit by about 20m, the outer surface of the extension section of the optical unit is provided with a spring protection sleeve, and two ends of the cable are respectively provided with a metal mesh sleeve fastened on the surface of the outer protection sleeve and a metal mesh sleeve connecting ring connected with a traction rope. When the invention is used for carrying out optical-electrical separation in construction and wiring, the optical units at the two ends of the cable are reserved with about 20m of extension sections, so that the requirement of the optical units entering a cross connecting cabinet or a wiring cabinet for connection can be met, the electric power units which do not need to reserve the extension sections can not be wasted, and the laying cost of the cable is reduced. The spring protection sleeve arranged on the outer surface of the extension section of the optical unit can protect the optical unit from being extruded, the metal net sleeves fastened on the surface of the outer sheath and the metal net sleeve connecting rings connected with the traction ropes are arranged at the two end parts of the cable, so that stress points are concentrated at the end parts of the cable when the cable is stretched by the traction ropes, and the optical unit is not stressed and cannot be damaged.
Description
Technical field
The present invention relates to a kind of Optical Fiber Composite cable that has optical communication and electric power transfer complex function concurrently, especially a kind of Optical Fiber Composite cable that is reserved with the light unit extension of certain-length at the cable two ends.
Background technology
The existing fiber composite cable, light unit and power unit in its cable core are isometric at the two ends of cable, when cable carries out light-electricity separation in construction wiring, need there be the length in reserve about 20m the light unit when entering cross-connecting box or distributing cabinet, power unit also can produce the power line of same length simultaneously.And in the wiring of electric power system, power unit is not had the requirement of length in reserve.Therefore, the power line of the same length that power unit produced is useless, can cause the waste of power line, increases the laid down cost of cable.
Summary of the invention
In order to overcome the deficiency of existing fiber composite cable, in the waste of cable minimizing power line in the construction wiring, save cost, the invention provides a kind of reservation light haplotype Optical Fiber Composite cable.
Reservation light haplotype Optical Fiber Composite cable provided by the invention comprises light unit and power unit in the cable core, respectively is provided with the extension of being longer than about power unit 20m in the light unit at the two ends of cable.
For the extension that makes cable light unit at its two ends when laying is not damaged; extension appearance in the light unit is provided with the spring protection cover, respectively is provided with a wire netting cover connecting ring that is fastened on the metal net on oversheath surface and is connected with pull rope at the both ends of cable.
Trailing cable can be provided with suspension ring at the tail end of pull rope for convenience, is provided with around light unit extension and bears steel wire.
The invention has the beneficial effects as follows: when cable carries out light-electricity separation in construction wiring, owing to the extension that is reserved with in the light unit at cable two ends about 20m, needs in the time of can satisfying the light unit and enter cross-connecting box or distributing cabinet and connect, then can not cause waste to the power unit that does not need to reserve extension, reduce the laid down cost of cable.The spring protection cover of the extension appearance of smooth unit of the present invention can protect the light unit not to be squeezed; Can make pull rope when stretching at the metal net that is fastened on the oversheath surface at the both ends of cable and the wire netting cover connecting ring that is connected with pull rope, stress point concentrates on cable end, and the light unit does not stress, and can not cause damage.
Description of drawings
Fig. 1 is the schematic diagram that two ends of the present invention are reserved with the extension of light unit; Fig. 2 is the structural representation that end of the present invention is provided with metal net that is fastened on the oversheath surface and the wire netting cover connecting ring that is connected with pull rope, has drawn the structure of an end among Fig. 2, and the structure of another end is identical, the Therefore, omited.
In Fig. 1, Fig. 2,1, power unit, 2, light unit extension, 3, oversheath, 4, the spring protection cover, 5, the metal net, 6, wire netting cover connecting ring, 7, pull rope, 8, bear steel wire, 9, suspension ring.
Embodiment
With reference to Fig. 1, Fig. 2; make when of the present invention; respectively be provided with than the light unit extension 2 about power unit 1 long 20m at the cable two ends; and spring protection cover 4 is set in light unit extension 2 appearances; a wire netting cover connecting ring 6 that is fastened on the metal net 5 on oversheath 3 surfaces and is connected with pull rope 7 respectively is set at the both ends of cable; for making things convenient for trailing cable, suspension ring 9 can be set at the tail end of pull rope 7, around light unit extension 2, be provided with and bear steel wire 8.In order to prevent the water inlet of cable and two ends, light unit, can be to cable end face and the sealing separately respectively of light unit end face.
