Abstract
The utility model provides a category-six twisted pair with a stable inner structure; the scheme comprises an outer layer insulation sheath, eight signal lines and a central support; the central support comprises an inner layer PE support, an outer layer elastic layer and a central support rod; a cross section is in a quadrangle star shape; four corners of the quadrangle star contact with the outer layer insulation sheath, and extend along the twisted pair so as to quartering an inner space of the outer layer insulation sheath; every two signal lines of the eight signal lines are mutually twisted to form four pairs respectively positioned in four spaces. The twisted pair not only can balance the inner structure of the outer layer insulation sheath, and also can reduce signal loss caused by cable extrusion on certain level.
Description
Technical field
The utility model relates to the twisted-pair feeder that a kind of network service is used, concrete is a kind of six class twisted-pair feeders.
Background technology
At present signal transmission is mainly take UTP twisted-pair feeder and optical fiber as main, wherein optical fiber is mainly used in the signal transmission of long distance, and short-range signal transmission is mainly UTP twisted-pair feeder, and twisted-pair feeder is mainly used in transportation simulator acoustic information, and in fact, twisted-pair feeder is equally applicable to the transmission of digital signal, particularly short-range communication, but in transmitting procedure, the decay of signal is large, and easily produce wave distortion, therefore, under very short distance and special electronics transmission technology condition, Double-strand transmission rate just can reach 100Mbps～155Mbps, existing six class twisted-pair feeders improve with having compared with five classes or super Category-5 twisted pair in structure significantly in shape, not only the diameter of cable is also thicker, and increase the crossing skeleton of insulation, four pairs of lines of twisted-pair feeder are placed in respectively in four grooves of crossing skeleton, the crossing skeleton of cable central authorities is the anglec of rotation with the variation of length, four pairs of twisted-pair feeders are stuck in the groove of skeleton, keep the relative position of four pairs of twisted-pair feeders, improve equilibrium response and the crosstalk attenuation of cable.In addition, guarantee that the balanced structure of cable is not destroyed in installation process.Therefore, its bandwidth can extend to 250Mbps or higher, and the crossing skeleton using is at present only generally the bracing frame of mutually perpendicular two PE materials, all can be because very large deformation occurs in twisting in its production at cable, transportation and installation process, thus serious even can bending not have the effect that keeps four pairs of twisted-pair feeder relative positions and balanced structure.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of prior art, be six class twisted-pair feeders of four jiaos of starriness and a kind of cross section is provided, this twisted-pair feeder can not only balance the structure of outer insulating sleeve inside, also can reduce to a certain extent the loss of signal that cable causes due to extruding simultaneously.
This programme is achieved by the following technical measures: these the novel Stability Analysis of Structures providing six class twisted-pair feeders, include outer layer insulation sheath, eight holding wires and center bearing bracket, eight holding wires are by insulating case and oxygen-free copper core conductor composition, center bearing bracket is by internal layer PE support, outer elastomer layer and central support posts composition, outer elastomer layer can be to setting up, in transportation twisted-pair feeder process, good cushioning effect is played in the deformation of the insulating case of eight holding wires that the twisting external force that twisted-pair feeder is subject to causes, whole center bearing bracket cross section is four jiaos of stars, four drift angles of four jiaos of stars contact with primary insulation sheath, radially extend along twisted-pair feeder, by the inner space quartering of primary insulation sheath, every two of eight described holding wires are twisted into four pairs mutually, lay respectively in four spaces, and central support posts can increase the bulk strength of central cross frame, improving cable is producing, stability in transportation and installation process, avoid the bending of squeezing the excessive central cross frame causing of power because turning round, visible to establish scheme more stable with respect to existing crux, more easily keep the balanced structure of eight holding wires.In addition, in order better to guarantee the rock-steady structure of outer layer insulation sheath inside, the direct selection of central support posts, should guarantee that two pairs of holding wires can not form in outer insulating sleeve inner space the form of arranged radially.
The beneficial effect of this programme can be learnt according to the narration to such scheme, be the center bearing bracket of four jiaos of stars owing to having adopted with central support posts and cross section in this scheme, make a novel twisted-pair feeder that provides there is more stable internal structure, be applicable to more complicated environment for use, meanwhile, the design of center bearing bracket outsourcing elasticity layer, can reduce the deformation that holding wire insulating case produces because of extruding, thereby reduce because impedance weakens the loss of signal bringing, improve signal transmission quality.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.

Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can find out by accompanying drawing 1, the six class twisted-pair feeders of this programme, include outer layer insulation sheath 1, eight holding wires and center bearing brackets, wherein eight holding wires form by insulating case 4 and oxygen-free copper core conductor 6, center bearing bracket is made up of internal layer PE support 5, outer elastomer layer 3 and central support posts 2, its cross section is four jiaos of stars, four drift angles of four jiaos of stars contact with outer layer insulation sheath 1, by the inner space quartering of outer layer insulation sheath 1, every two above-mentioned of eight holding wires are twisted into four pairs mutually, lay respectively in four spaces.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
