Abstract
The utility model discloses a self-supporting optical cable and relates to the field of cables, so as to solve the technical problems that the self-supporting optical cable in the prior art is poor in wind resistance performances and snow and ice resistance performances. The self-supporting optical cable comprises a main cable and a supporting cable; the main cable and the supporting cable are connected side by side; and a plurality of ventilation slots are arranged at the place where the main cable and the supporting cable are connected. The self-supporting optical cable can be applied to cable network construction, and particularly a signal transmission cable.
Description
[technical field]
The utility model relates to a kind of cable.
[background technology]
When self-support cable possesses all features of ordinary optical cable, during built on stilts laying, can avoid secondary construction, therefore be applied in networking more and more.Self-support cable is built on stilts, and lay inevitably will be through such as many many ice and snow of beam wind areas such as coastal, mountain valleys, be in all the year round in the field extreme environment of windy or many ice and snow, quality to self-support cable, particularly wind resistance and anti-ice-snow performance have very high requirement.Once the not good light signal that causes of wind resistance and anti-ice-snow performance interrupts, and will cause serious consequence.Traditional self-support cable mostly is 8 font structures, and main push-towing rope is connected with umbilical cord with holding between cable, main push-towing rope and to hold cable all rounded, so the sidewall of optical cable while being subject to wind impulsive force large, ice and snow easily adheres on circular outer wall, the poor-performing of its wind resistance and anti-ice-snow.
[summary of the invention]
The technical matters that the utility model solves is to provide a kind of self-support cable, strengthens the wind resistance of self-support cable and the ability of anti-ice-snow.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A self-support cable, comprises main push-towing rope and holds cable, described main push-towing rope and hold cable and be connected side by side, and described main push-towing rope is provided with some ventilation slots with the junction of holding cable.
Further, described in hold cable upper end be provided with along two relatively close inclined-planes of short transverse, described two inclined-planes are arranged on the both lateral sides of holding cable.
Further, the upper end of described main push-towing rope is trapezoidal, trapezoidal upper base and hold cable and be connected.
The lower end of holding cable further, is that trapezoidal, trapezoidal upper base is connected with main push-towing rope.
The beneficial effects of the utility model:
Self-support cable of the present utility model, is provided with ventilation slot in main push-towing rope and the junction of holding cable, while being subject to wind in the both sides of optical cable, air flow energy passes through from ventilation slot, therefore reduce the impact of wind-force to optical cable, strengthened the wind loading rating of optical cable, reduced the impact that high wind transmits optical cable signal.
These features of the present utility model and advantage will be below embodiment, accompanying drawing in detailed exposure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is longitudinal cross-section of the present utility model schematic diagram;
Fig. 2 is front view of the present utility model.
[embodiment]
The utility model provides a kind of self-support cable, and comprise main push-towing rope and hold cable, main push-towing rope and hold cable and be connected side by side, main push-towing rope is provided with some ventilation slots with the junction of holding cable.Air-flow can reduce the impulsive force of air-flow to optical cable smoothly by the both sides of optical cable by ventilation slot, improves the wind loading rating of optical cable.And ventilation slot the material consumption that can reduce optical cable integral body is set, alleviate optical cable weight.
Accompanying drawing below in conjunction with the utility model embodiment is explained and illustrated the technical scheme of the utility model embodiment, but following embodiment is only preferred embodiment of the present utility model, not all.Embodiment based in embodiment, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to protection domain of the present utility model.
With reference to figure 1 and Fig. 2, shown in a kind of self-support cable, comprise main push-towing rope 1 and hold cable 2, optical fiber 11 is set in main push-towing rope 1, holds messenger wire 21 is set in cable 2, main push-towing rope 1 with hold cable 2 and be connected side by side, main push-towing rope 1 is provided with some ventilation slots 3 with the junction of holding cable 2, ventilation slot 3 is intervally arranged along cable length direction, and ventilation slot 3 runs through the both lateral sides face of optical cable, has strengthened the wind loading rating of optical cable.And in the utility model, main push-towing rope 1 is closely connected as a body with the oversheath that holds cable 2, cancel in prior art and be connected to main push-towing rope and hold the umbilical cord between cable, can reduce the lateral area of optical cable, therefore reduce the lifting surface area in beam wind situation, further also improve the wind loading rating of optical cable; And this connected mode, compares umbilical cord and connects, and has strengthened the strength of joint holding between cable and main push-towing rope.
Wherein, the upper end of holding cable 2 is provided with along two relatively close inclined-planes of short transverse, and two inclined-planes are arranged on the both lateral sides of holding cable 2.Preferred upper end is taper, and the two side of taper is this inclined-plane, is attached to the ice and snow holding on cable, because Action of Gravity Field is along inclined-plane landing, therefore reduce snow and ice cover on optical cable, prevent that optical cable from causing optical cable to be pulled off owing to adhering to ice and snow, improved the anti-ice-snow ability of optical cable.
In like manner, the upper end of main push-towing rope 1 is arranged to trapezoidal, trapezoidal upper base and is held cable 2 and be connected.Trapezoidal is isosceles trapezoid, and the waist of isosceles trapezoid both sides forms slope, therefore can reduce the ice and snow adhering on main push-towing rope equally, has improved the anti-ice-snow ability of optical cable; Trapezium structure is less than square and circular area simultaneously, reduces the weight of optical cable.The lower end of main push-towing rope 1 is designed to semicircle, and semicircle is compared square, has reduced material consumption, has also reduced optical cable weight.
Further, hold the lower end of cable 2 also for trapezoidal, trapezoidal upper base is connected with main push-towing rope 1.Preferred trapezoidal is isosceles trapezoid.The lower end of holding cable be arranged to trapezoidal after, the thickness holding between cable two bottom sides increases, and can strengthen main push-towing rope and hold the connection area between cable, strengthens strength of joint, even at main push-towing rope and hold between cable and slot and also can not affect strength of joint.
By above-described embodiment, the purpose of this utility model is by fully effective having reached.The personage who is familiar with this technology should be understood that the utility model includes but not limited to accompanying drawing and the content of describing in embodiment above.Any modification that does not depart from function and structure principle of the present utility model all will be included in the scope of claims.
