Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the structural representation of the xsect of the skeleton cable that Fig. 1 provides for the utility model embodiment.
In a kind of specific embodiment, present embodiments provide a kind of skeleton cable, this skeleton cable is mainly applied to and both can transmits electric signal and also can transmit on the mixed type skeleton cable of light signal.This skeleton cable wrap draws together reinforcement 1, skeleton 2 and cylindrical conductor 3, and cylindrical conductor 3 is generally the twisted pair wire for transmission of electric signals, can certainly be single xsect is columniform conductor.Skeleton 2 is set in the outside of described reinforcement 1, and the xsect of skeleton 2 is annular.The arranged outside of skeleton 2 has multiple groove evenly arranged around reinforcement 1, namely institute's fluted one-tenth one circle is arranged, groove is for placing conductor, but one should be had in multiple groove at least for placing cylindrical conductor 3, namely at least one groove is the cylindrical conductor groove 21 for placing cylindrical conductor, the bottom land of this cylindrical conductor groove 21 increases gradually to the width of notch, namely this cylindrical conductor groove xsect can for trapezoidal, there is the arc of minor arc or other is irregularly shaped, namely the notch of this cylindrical conductor groove 21 presents the trend of expansion.If need to be provided with the optical fiber 7 that xsect is rectangle in skeleton cable, a groove is preferably at least made to be U-type groove 22, be placed with the optical fiber 7 that xsect is rectangle in this U-type groove 22, because be the optical fiber 7 of rectangle for xsect, use U-type groove 22 effectively can improve the space utilization rate of groove.
Xsect due to cylindrical conductor 3 is circular, so generally only need the middle part clamping cylindrical conductor 3 just cylindrical conductor 3 can be taken out or put into cylindrical conductor groove 21.So for the Lower Half of cylindrical conductor groove 21 then can do very narrow, be even too narrow to and directly contact with the Lower Half of cylindrical conductor 3.And to be generally used for the xsect of fore-end of the chucking device clamping out cylindrical conductor 3 be triangle, and the groove width of cylindrical conductor groove 21 is increased gradually from bottom land to notch, also be very beneficial for stretching into of chucking device, make to ensure that the convenience taking out and put into cylindrical conductor 3.Simultaneously because the xsect of skeleton 2 is annular, described skeleton 2 is from outside to inside in gradual shrinkage, and a skeleton 2 is after the setting position of bottom land determining groove, and the number that can arrange groove is just relevant with the width of bottom land.And the notch of cylindrical conductor groove 21 to bottom land is also gradual shrinkage, the position between multiple groove can be made so compacter.So when skeleton cable needs the groove of same quantity, it is more compact that cylindrical conductor groove 21 can be arranged, so also less for the restriction of the diameter of skeleton 2.And then the excessive problem of skeleton cable diameter can be solved.Based on foregoing description, when a plurality of the grooves is present, the maximum activity space due to each groove is fan-shaped, and the xsect preferably making cylindrical conductor groove 21 is isosceles trapezoid, enables the convergent trend of skeleton 2 can be identical with the convergent trend of cylindrical conductor groove 21.
In order to more protect the electric conductor or optical fiber 7 of putting into groove, preferably have waterstop 4 in the arranged outside of skeleton 2, waterstop 4 is generally the nonwoven fabrics scribbling water-proofing powder.Waterstop 4 has stronger water absorptivity, increase of expanding after waterstop 4 runs into water.Full groove can be filled rapidly, to block the notch of groove, play the effect of waterproof.
Considering, if make the groove depth of all U-type groove 22 for placing optical fiber 7 the same, and when needing the number ratio of the optical fiber be equipped with in some U-type groove 22 less, now will leave great space in U-type groove 22.And due to the collision limited height of waterstop 4, the gap in full U-type groove 22 cannot be filled due to waterstop 4 when meeting water, so the water infiltrated may longitudinally circulate, and then cause having water to enter in optical fiber 7, have a strong impact on life-span and the use of optical fiber 7.So preferably make the groove depth of U-type groove corresponding with the height of the optical fiber 7 putting into U-type groove, when namely causing optical fiber height lower when the optical fiber 7 put into is less, preferably make the groove depth of U-type groove also more shallow accordingly, it is emphasized that herein, the concrete upper side of optical fiber 7 and the difference of the groove depth of U-type groove should determine according to the expansion coefficient of waterstop 4, the expansion coefficient of waterstop 4 is larger, then difference can increase.
When being provided with the electric conductor for transmission of electric signals in this cable, such as, when there is the twisted pair wire being used for transmission of electric signals, reinforcement 1 is preferably made to be non-metal reinforcement member, because metal reinforcement easily interferes with the transmission of electric signal.Non-metal reinforcement member can also play the effect alleviating whole skeleton cable weight simultaneously.General reinforcement 1 can adopt fibre reinforced composites reinforcement.Be arranged on optical fiber in skeleton 27 and other conductor to can more protect, preferably can have fire retardant jacket 5 in the arranged outside of waterstop 4, namely this fire retardant jacket 5 can play the effect of preliminary water proof and dust proof.For the ease of getting rid of outermost fire retardant jacket 5, and be unlikely to the skeleton 2 damaging fire retardant jacket 5 inside, preferably arrange between fire retardant jacket 5 and waterstop 4 and tear rope 6, when fire retardant jacket 5 got rid of by needs, only need to pull out to be positioned at and tear rope 6 inside fire retardant jacket 5, tearing rope 6 can make fire retardant jacket 5 tear out an opening along the bearing of trend tearing rope 6, and without the need to making this opening with cutter again.In order to prevent skeleton cable when being subject to tension force or pulling force, because the tension of skeleton cable inner conductor and anti-pressure ability are strong, so be preferably provided with aramid yarn at the bottom land of groove.When the conductor of skeleton cable inside affords pulling force time, aramid yarn can share a part of acting force, decreases the pulling force that conductor bears.Aramid yarn has very good anti-tensile tensile property, so whole skeleton cable can be made not to be damaged under strong wind or large percussive action simultaneously.
