Description
Technical field
The utility model relates to the technical field of communication data cable, specifically a kind of data cable.
Background technology
In comprehensive wiring site operation, test for a project, once return loss RL does not pass through in link test, the analysis of instrument HDTDR time domain model generally will be adopted to follow the tracks of, find that position is at the two ends of link, connect hardware got rid of by reinstalling after removing this part cable, or rewiring.The fault of return loss RL is difficult to be got rid of by straightforward procedure.There is product quality problem when horizontal cable self or suffer at construction midline cable to damage the fault that can cause return loss RL.After construction midline cable has connected up, namely the state of whole cable has shaped, and when test is pinpointed the problems, does not generally solve by simple routing again or replacing module.Therefore, in the production process of cable, by improving the concentricity of insulation core wire, keeping stability, the consistency of tension force, adopting pre-back twist technology, select the key elements such as the raw material of high-quality, the transmission performances such as the impedance of guarantee cable and return loss.
At present, data cable outsidely after four pairs of line strands extrudes one deck sheath and make.In this structure, the right position of four lines is easy to mobile along with the construction in the external world lays.One is that pulling force is excessive in construction, and the overall structure of cable easily changes, and namely causes cable to be out of shape, and makes cable transmission hydraulic performance decline; Two is that too small the causing between line pair and line pair of bending radius is subject to serious extruding, and even crust is damaged to make the distortion of cable, causes transmission performance to decline.Above-mentioned easily cause data cable to occur after construction return loss, impedance are defective.
Summary of the invention
The purpose of this utility model is the deficiency for solving above-mentioned technology, provides that a kind of reasonable in design, structure is simple, stable performance and can ensure the data cable of the transmission characteristics such as the impedance of data cable and return loss.
Technical solution adopted in the utility model is: a kind of data cable, comprise locating rack, the panchromatic spectral line pair of pair twist, protective sleeve, it is characterized in that locating rack is that elastomer is in the middle of cable core, the arcs such as four Bian Cheng of elastomer locating rack, the inside of locating rack is provided with fortifying fibre, on locating rack, the arc center line such as adjacent both sides is mutually vertical, the arcs such as four limits of locating rack there is a pair panchromatic spectral line pair of horizontal pair twist respectively, locating rack and four to the panchromatic spectral line of horizontal pair twist to forming cable core, protective sleeve is extruded in cable core outside, the endoporus circumferential edge of protective sleeve is Wave curved shape.
The utility model is reasonable in design, compact conformation, easily manufactures, cost is low, cable arrangement is stablized, mechanical performance and transmission performance good, can be used for indoor horizontal wiring, indoor vertical wirings, outdoor built on stilts wiring etc., be widely used in intelligent building wiring, monitoring, high-speed data center etc.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1, fortifying fibre, 2, locating rack, 3, copper conductor, 4, insulating barrier, 5, protective sleeve, 6, endoporus circumferential edge.
Embodiment
As shown in Figure 1: a kind of data cable; comprise locating rack 2, the panchromatic spectral line of pair twist to, protective sleeve 5; its locating rack 2 is that elastomer is in the middle of cable core; the arcs such as four Bian Cheng of elastomer locating rack 2; the inside of locating rack 2 is provided with fortifying fibre; on locating rack 2, the arc center line such as adjacent both sides is mutually vertical; the arcs such as four limits of locating rack 2 there is a pair panchromatic spectral line pair of horizontal pair twist respectively; locating rack 2 and four to the panchromatic spectral line of horizontal pair twist to forming cable core; extrude protective sleeve 5 in cable core outside, the endoporus circumferential edge 6 of protective sleeve 5 is in Wave curved shape.
In production and application, locating rack 2 adopts pliable and tough elastomer to extrude and forms, when data cable is used for horizontal wiring, locating rack 2 inside can arrange fortifying fibre 1, the arc sides such as four limits of locating rack 2 place four to the panchromatic spectral line pair of horizontal pair twist successively according to data cable chromatogram order white orchid/orchid, white tangerine/tangerine, in vain green/green, white palm fibre/palm fibre, each line forms the mode of being twisted with " S " according to the pitch of design by two insulated single wires is evenly stranded, and every root insulated single wire extrudes high density polyethylene (HDPE) insulating barrier 4 outside real core copper conductor 3; Four pairs of panchromatic spectral lines are twisted into cable core to the mode that the laying up pitch again according to designing requirement twists with " S ", extrude protective sleeve 5 outside cable core, and the inner surface of protective sleeve is uniform waveform inwall 6.
Locating rack 2 in the middle of the utility model adopts pliable and tough elastomer to extrude and forms, the arcs such as four Bian Cheng, both can static line to position, when avoiding constructing, line is to position arbitrarily movement, mechanical damping effect can be played again, avoid causing line to mutual crimp, also can increase the distance between line pair simultaneously, thus improve return loss, impedance behavior and cross-talk performance; When for built on stilts laying, for increasing mechanical performance, while extruding locating rack 2, a fortifying fibre 1 is longitudinally placed in heart position wherein; When for horizontal laying, fortifying fibre 1 can not be placed when extruding locating rack 2 in center.Protective sleeve adopts the extrusion way of half crowded pipe, and protective sleeve material selects different materials according to the environmental requirement that cable uses, and machine room and house wiring generally use halogen-free low-smoke flame retardant material LSZH, also can use polyvinylchloride; Outdoor general employing LLDPE material LLDPE.Protective sleeve core rod is extruded, by line to being extruded in the middle of locating rack and waveform curved surface.When constructing, line can not along with the pulling force in the external world and bending and arbitrarily mobilely become bent distortion to position, its structural entity even, ensures that the transmission characteristic such as impedance, return loss can not change along with cable wiring manufacture.
The utility model compact conformation, rationally, cable core structure stable and uniform, can be used for surpassing five class data cable, also can be used for six classes, surpass six class data cable, lay for indoor horizontal, light current well vertical wirings, outdoor built on stilts wiring, mechanical performance and transmission performance good, can be widely used in the gigabit ethernet network such as monitoring, intelligent building wiring wiring.
