Description
Technical field
The utility model relates to optoelectronic composite cable technical field, is specifically related to a kind of communication equipment tension resistance to compression optoelectronic composite cable.
Background technology
Along with the continuous upgrading of communication system, the operating frequency of various communication equipment is also more and more higher, the exchanges data amount of equipment room is also increasing, the exchanges data of equipment room relies on traditional copper cable transmission more and more difficult, this cost performance being not only embodied in copper cable is more and more lower, the more important thing is due to copper cable narrow bandwidth, sometimes even cannot realize the Signal transmissions of longer distance under upper frequency.In order to solve the problem, increasing communication system adopts wider, that transmission attenuation the is little optical fiber of communication bandwidth to realize between disparate modules or the transfer of data of equipment room.Under these use occasions, usually also can run into part of module or equipment needs small-power feed or transmission of electric signals simultaneously, so optoelectronic composite cable enters the visual field of people.
But, at present in the promoting the use of optoelectronic composite cable, still there is problem, main cause is the physical characteristic of optical fiber itself, with regard to optical fiber, it is all more fragile at the anti-pressure ability of horizontal resistance to tension or longitudinal direction, and in current optoelectronic composite cable structure, only by the conductor wire of composite rope inside and the sheath of composite rope, optical fiber is protected, in actual use, inventor finds at present like this knot protection structure unreliable, such as in composite rope bending process, when the amplitude of bending is larger, the as easy as rolling off a log appearance fracture of optical fiber, so in installation process, and in maintenance after mounting, all need extra careful, otherwise as easy as rolling off a logly cause fibercuts, and whole optoelectronic composite cable was lost efficacy.Bring great inconvenience to the popularization of current optoelectronic composite cable and use, constrain the development of optoelectronic composite cable.
So based on above-mentioned, being badly in need of at present one can good protection optical fiber, reduces fibercuts risk, and then the optoelectronic composite cable conveniently promoted the use of.
Utility model content
The utility model object is for current optoelectronic composite cable above shortcomings, provides one can good protection optical fiber, reduces fibercuts risk, and then the optoelectronic composite cable conveniently promoted the use of.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of communication equipment tension resistance to compression optoelectronic composite cable, comprise cable core, described cable core includes conductor wire unit and fiber unit, and described cable core outer cladding is provided with sheath, and between described cable core and described sheath, armouring has steel band protecting jacket.By arranging steel band protecting jacket cable core is armoured, first be the anti-pressure ability that improve optoelectronic composite cable longitudinal direction, namely, when composite rope is subject to the extruding perpendicular to composite rope length direction, owing to there being the support of steel band protecting jacket, protection fiber unit that can be good, avoids fiber unit to be damaged by pressure break; Simultaneously; due to the existence of steel band protecting jacket; make optoelectronic composite cable not flexible; avoid fractureing of fiber unit, though when optoelectronic composite cable stressed bending time, also usually can produce a larger bending radius at crooked position; so also can realize avoiding fractureing of fiber unit; so by said structure, the fiber unit in protection optoelectronic composite cable that can be good, avoids in use with during later maintenance damaging fiber unit.
As preferably, described steel band protecting jacket is spiral steel belt protective sleeve.Adopt spiral steel belt protective sleeve, the bending of optoelectronic composite cable can be conducive to, facilitate the actual use of the optoelectronic composite cable of the application, but not easily form dead angle again when bending, can keep providing enough large bending radius to avoid fiber unit to be fractureed.
Further, filler is filled with in the gap between described cable core and described steel band protecting jacket.In gap between steel band protecting jacket and cable core, filler is set, avoids cable core to damage fiber unit at steel band protecting jacket internal slide.
Further, also braid is provided with between described steel band protecting jacket and described sheath.Increase the tensile strength of optoelectronic composite cable by arranging braid, avoid when optoelectronic composite cable tension, fiber unit is pulled off and splits, and then further improves the reliability of optoelectronic composite cable involved by the application.
Further, described braid is steel wire braid.Adopting steel wire braid, is first have good mechanical property, further improves the tensile strength of optoelectronic composite cable; Meanwhile, steel wire braid also opens the effect of electromagnetic shielding, avoids the signal of fiber unit internal transmission to be subject to external electromagnetic interference, ensures the transmission quality of signal.
Compared with prior art, the beneficial effects of the utility model are:
1, the optoelectronic composite cable involved by the application, by arranging steel band protecting jacket cable core is armoured, first be the anti-pressure ability that improve optoelectronic composite cable longitudinal direction, namely, when composite rope is subject to the extruding perpendicular to composite rope length direction, owing to there being the support of steel band protecting jacket, protection fiber unit that can be good, avoids fiber unit to be damaged by pressure break;
2, because steel belt protection is enclosed within existence, make optoelectronic composite cable not flexible, avoid fractureing of fiber unit, even if when optoelectronic composite cable stressed bending time, also usually can produce a larger bending radius at crooked position, so also can realize avoiding fractureing of fiber unit, so pass through said structure, fiber unit in protection optoelectronic composite cable that can be good, avoids in use with during later maintenance damaging fiber unit;
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model,
Mark in figure: 1-cable core, 2-conductor wire unit, 3-fiber unit, 4-sheath, 5-steel band protecting jacket, 6-filler, 7-braid.
