Abstract
The utility model discloses a self-adhesion type symmetrical data cable. The self-adhesion type symmetrical data cable comprises conductors, insulators and jackets, wherein the conductors and the insulators form wire cores, two wire cores form a pair, and two pairs are formed; a layer of self-adhesion polyethylene film is arranged outside each wire core, so the pitch change of a single wire is not influenced during cabling twisting, and signal transmission is more stable. Besides, with the adoption of the structure, when terminals of data cable core wires are butted, an operator can easily distinguish the arrangement sequence of white wire cores, and butting operation of terminals is facilitated.
Description
Technical field
The utility model relates to a kind of self-adhering-type symmetric data cable, has the performance of stable transfer signal.
Technical background
The symmetric data cable has adopted the mutual stranded mode of the core of a pair of mutual insulating to resist a part of external electromagnetic wave interference.Twist the copper conductor of two insulated together mutually by certain density, can reduce the degree that signal disturbs, the electric wave that the electric wave of each root lead radiation in transmission can be sent on other single line is offset.During actual the use, because packing, lay and other human factors can cause twisted-pair feeder constantly crooked, its pitch can change, and twisted-pair feeder is in transmission range, and channel width receives certain limitation, and there is stability scarcely in transmission signals.Therefore, for the structure that makes twisted-pair feeder is more stable, no matter add one deck self-adhering-type polyethylene film at cost, technology all is a kind of good selection on the performance.And can carry out the end-on operation more easily efficiently.
Summary of the invention
The utility model patent provides a kind of self-adhesion symmetric data cable that strengthens transmission performance stability, and it is realized through following technical scheme:
The utility model patent discloses a kind of self-adhering-type symmetric data cable; Comprise conductor, insulation, sheath; Conductor constitutes core with insulation, and core contains one deck self-adhesion polyethylene film at the external bread of each core directly in pairs; Thereby avoided influencing when stranded the situation of the pitch variation of single line, made transmission signals more stable because of stranding.In addition, when this structure more can make each end-on of data cable heart yearn, the operator distinguished putting in order of white core easily, had made things convenient for the end-on operation.
The advantage of the utility model patent is: the cable through at the symmetric data cable adds one deck self-adhesion polyethylene film to the outside; Make cable stranded at stranding; Packing, and lay with other external force factor effects under, avoid core to producing displacement by a relatively large margin; Ensured the structural behaviour of symmetric data cable, thereby the electric property that ensures the symmetric data cable is more stable.This structure not only can be used for 4 pairs of data telecommunication cables, also can be used for big logarithm cable.Aspect terminal fitting,, make the easier ordering of telling core of operator to be difficult for align-err because the every pair of core all has the encirclement of self-adhesive layer.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1 conductor; 2 insulation; 3 self-adhesive layers; 4 sheaths.
Embodiment
Below in conjunction with Fig. 1 the utility model is done and to be further described: a kind of self-adhering-type symmetric data cable, comprise conductor 1, insulation 2, sheath 4, it is characterized in that: to the outside, also have one deck self-adhesive layer 3 at every pair of core that constitutes by conductor 1 and insulating barrier 2.
Wherein, four groups of core colors shown in the figure one are that orange is white, and are blue white, green white, and the white pitch of palm fibre is respectively 17.0mm, 12.5mm, 14.5mm, 19.0mm.Because the effect of self-adhesive layer 3 makes it in the time of stranding, guarantees that this pitch variation amount is minimum, has guaranteed that its performance is more stable.
Claims (2)
1. a self-adhering-type symmetric data cable comprises inner wire (1), insulation (2), sheath (4), it is characterized in that: there is one deck self-adhesive layer (3) the core outside in every pair of conductor (1) and insulation (2) formation.
2. self-adhering-type symmetric data cable according to claim 1 is characterized in that: described self-adhesive layer (3) material therefor is the single side self polyethylene.
