Abstract
The utility model discloses a twisted pair cable with stable data transmission effect and bending-fatigue resistance, comprising a cable core which comprises four pairs of twinning core threads. Filling bars are arranged among the four pairs of twinning core threads. The cross section of the filling bar is a spiral roll typed structure with four extension arms. In the twisted pair cable of the utility model, the section of filling bar with the spiral roll typed structure is adopted, which avoids the damage to a shielding layer or the inner of a sheath caused when the cable is bended, and makes the effect of data transmission more stable.
Description
Technical field
The utility model relates to a kind of data cable, relates in particular to a kind of twisted-pair cable.
Background technology
Along with the communication and the fast development of the Internet, also more and more higher to the performance requirement of the cable that transmits data.
China's utility model patent 200420044473.3 discloses a kind of LAN with shield type six class cables, comprises sheath, cable core and screen, and described screen is a three-decker, polyester belt, aluminium foil layer and outer polyester belt in being followed successively by from the inside to the outside; Has earth connection between interior polyester belt and the aluminium foil layer; Described cable core is made up of four pairs pair twist heart yearn, has different strands to pitch between every pair of heart yearn; Be provided with the cross filling bar that is used to isolate between described four pairs of heart yearns.
In this technology; though the effects such as respectively organizing twisted-pair feeder, support sheath of isolating has been played in the use of cross filling bar; but owing in the sheath cross filling bar is housed; the resistance when twisted-pair cable bending, turnover that is is bigger; and the cross filling bar might cause damage to screen or sheath inside; be difficult to protect inner twisted-pair feeder, may influence the transmission of data.
Summary of the invention
The utility model provides the twisted-pair cable of a kind of transfer of data effect stability, anti-flexural fatigue.
The twisted-pair cable that has packing in a kind of comprises the cable core that contains four pairs of pair twist heart yearns, is provided with the packing that is used to isolate between described four pairs of pair twist heart yearns, and the cross section of packing is the spiral wound configuration that has four adjutages.
Four adjutages are all drawn from twisted-pair cable kernel of section point, outwards disperse uniformly along pitch, and the twisted-pair cable cross section is divided into four intervals, and four pairs of pair twist heart yearns place respectively in these four intervals.
Also be provided with in the interval in described four intervals in addition and tear rope, tear rope and can adopt materials such as high-strength nylon, tearing rope not only can use when needs are pushed sheath aside, more can add man-hour at cable, stretching, prevent when twining cable that the inner twisted pairs generation type that is stretched from becoming, guarantee all even transfer of data effect of wire diameter.
It is the packing of spiral wound configuration that the utility model twisted-pair cable adopts the cross section, and the damage of having avoided when cable is crooked packing that screen or sheath inside are caused makes the transfer of data effect more stable.
Description of drawings
Fig. 1 is the utility model twisted-pair cable schematic cross-section.
Embodiment
Referring to accompanying drawing 1, the utility model twisted-pair cable comprises the cable core that contains four pairs of pair twist heart yearns 2, and four pairs of pair twist heart yearn 2 external packets are wrapped with sheath 1.
Four pairs of 2 of pair twist heart yearns are provided with the packing 3 that is used to isolate, and the cross section of packing 3 is the spiral wound configuration that has four adjutages.Four adjutages are all drawn from twisted-pair cable kernel of section point, outwards disperse uniformly along pitch, and the twisted-pair cable cross section is divided into four intervals, and four pairs of pair twist heart yearns 2 place respectively in these four intervals.
Also be provided with in the interval in described four intervals in addition and tear rope 4, tear rope 4 and adopt high-strength nylon.Tear rope and 4 not only can when needs are pushed sheath aside, use, more can add man-hour,, guarantee all even transfer of data effect of wire diameter stretching, prevent when twining cable that the inner twisted pairs generation type that is stretched from becoming at cable.
It is the packing of spiral wound configuration that the utility model twisted-pair cable adopts the cross section, and the damage of having avoided when cable is crooked packing that screen or sheath inside are caused makes the transfer of data effect more stable.
Claims (3)
1, have the twisted-pair cable of packing in a kind of, comprise the cable core that contains four pairs of pair twist heart yearns, it is characterized in that: be provided with the packing that is used to isolate between described four pairs of pair twist heart yearns, the cross section of packing is the spiral wound configuration that has four adjutages.
