Abstract
The invention provides a filling strip of a submarine photoelectric compound cable to provide residual length for an optical unit, which mainly comprises a filling strip body, a circular groove is provided on the filling strip body. Because of the structure of providing a circular groove on the filling strip body, when the compound cable is tensioned, the optical unit can freely move to the compound cable core from the side of the filling strip, so that the optical unit is not acted by the tension, the optical transmission performance is not changed.
Description
Technical field
The present invention relates to a kind of light unit that can prevent and be subjected to the effect of external force, the sea floor optoelectronic composite cable packing of surplus length is provided for the light unit.
Background technology
At present, the filler that the compound stranding in light unit is used in the known sea floor optoelectronic composite cable is the polypropylene tearing film, during stranding, light unit and polypropylene tearing film are together stranded, cable core rounding not behind the stranding, the position of light unit in composite rope can't be fixed, and stretched or the external force of coiling in the BENDING PROCESS is done the time spent at composite rope, the light unit is easy to preferential stressed effect, and influences optical transmission performance.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome the light unit is used in the existing sea floor optoelectronic composite cable filler the position of light unit in composite rope can't be fixed and the cable core deficiency of rounding not, prevent that the light unit of giving that the light unit is subjected to the effect of external force from providing the sea floor optoelectronic composite cable packing of surplus length.
The object of the present invention is achieved like this: a kind of sea floor optoelectronic composite cable packing of surplus length being provided for the light unit, comprise packing body 1, and on packing body 1, be provided with groove 7.Described groove 7 is a circular groove.Circular groove 7 is tangent with the insulated wire cores 3 of adjacent two band waterproof sheaths, and circular groove 7 diameters are greater than the diameter of light unit 2.
The sea floor optoelectronic composite cable packing of surplus length being provided for the light unit provided by the present invention, by the structure of circular groove is set on the packing body, when composite rope is subjected to stretching, the light unit can move freely to the composite rope cable core from the side of packing, thereby the light unit is not subjected to the effect of pulling force, and optical transmission performance is constant.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the embodiments of the invention structural representations.
Embodiment
Concrete structure of the present invention is as follows: a kind of sea floor optoelectronic composite cable packing of surplus length being provided for the light unit, comprise packing body 1, and on packing body 1, be provided with groove 7.Described groove 7 is a circular groove.Circular groove 7 is tangent with the insulated wire cores 3 of adjacent two band waterproof sheaths, and circular groove 7 diameters are greater than the diameter of light unit 2.
When the present invention is applied to cable, the packing in the first construction drawing 1.What packing 1 was close in light unit 2 cuts out circular groove 7, and with the insulated wire cores 3 stranded strandings of band waterproof sheath, the cable outermost layer is a serving 6, be armouring wire 5 in the serving 6, and armouring wire 5 is interior to be inner covering, as shown in Figure 2.When composite rope is subjected to stretching, light unit 2 can preferential stressed effect, and when the surplus length that is elongated to the light unit when composite rope was used up, light unit 2 was tangent with the insulated wire cores 3 of adjacent two band waterproof sheaths, the stressed again effect of composite rope and when further extending, light unit 2 just is subjected to the effect of pulling force.
Claims (1)
1. sea floor optoelectronic composite cable packing of surplus length being provided for the light unit, comprise packing body (1), it is characterized in that: on packing body (1), be provided with groove (7), groove (7) is a circular groove, groove (7) is tangent with the insulated wire cores (3) of adjacent two band waterproof sheaths, and groove (7) diameter is greater than the diameter of light unit (2).
