Abstract
The utility model discloses a data cable with central skeleton, which essentially consists of an insulated lead and a jacket. The cable is characterized in that a multi-costal central skeleton is arranged in the jacket and the insulated lead is arranged in the cells of the skeleton. The utility model has a reasonable structure and an art design. When the cable receipts an outside force, the structure of the cable can keep stability so as to improve the stability of all the parameters of the cable, in the meantime, the working frequency of the cable are improved, which accelerates the speed of data transmission. The utility model is worthy of being extended.
Description
The utility model relates to a kind of data cable, particularly relates to the high-speed data cable that a kind of broadband LAN is used.
Along with computer network rapid development, network is constantly enlarging, is extending, the consumption of the data cable of the usefulness of arranging net, and increasing progressively with bigger amplitude every year.At present, data cable not only is used for the in-house network wiring of enterprise and institution and the comprehensive wiring system in intelligent building, and along with the propelling of China's digitalized city engineering, data cable has begun to enter the residential quarter, with cable of cable TV, lay to every household.Simultaneously, the amount of information of network communication also rapidly increases, and requires network to have the speed of wider frequency range and Geng Gao.This just requires the operating frequency of data cable higher, and transmission speed is faster.But present data cable exists many disadvantages, can not satisfy the network requirement that improves day by day.
The data cable structure of current popular is, eight thoroughly do away with the edge single lines at first by in twos to being twisted into four pairs, again with the stranded stranding of this four twisted pair wire, squeeze into sheath then and become finished cable.The shortcoming of this cable is: because four twisted pair wires are direct stranded strandings, relative position between them only depends on cable cover(ing) to be fixed, so cable is done the time spent being subjected to external force, stretching one extruding force that traction force when for example laying, cable are produced by structure self by bending time the etc., the relative position of its four twisted pair wire can change, even cable is in knitting cycle, its structural parameters also can change, the variation of this construction of cable parameter can cause cable performance, such as multiple parameters deteriorations such as four ripple losses, input impedance, near-end crosstalk, far-end crosstalks.This has seriously limited the operating frequency and the message transmission rate of data cable, also can cause the phenomenon of doing over again in the cable laying process simultaneously.
The purpose of this utility model provides and a kind ofly can effectively overcome above-mentioned defective, and Stability Analysis of Structures has the data cable of center framework reliably.
Technical solutions of the utility model are, a kind of data cable with center framework mainly is made up of insulated conductor and sheath, and its characteristics are: be provided with a center framework in the sheath, place insulated conductor in the compartment of skeleton.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion, the utility model is rational in infrastructure, is skillfully constructed, under the situation that is subjected to the external force effect, it is stable that the structure of cable can keep, thereby effectively improved the stability of the parameters of cable, the operating frequency of cable is improved simultaneously, and message transmission rate is accelerated, its performance can reach the level of CAT5, CAT5e, CAT6, CAT7 even the higher level of American TI A/EIA568A/B and NEMA66-1999 defined, tool promotional value.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, center of the present utility model is criss-cross center framework 1, places four pairs of twisted-pair feeders 2 respectively in its four compartments, extrudes one deck sheath 3 again outside it.Wherein, the monolateral height of center framework rib can be 0.5-2 times of twisted-pair feeder maximum gauge, and the thickness of rib is 0.1-0.5 times of the monolateral height of rib.It can be by other polymer such as polyethylene or fluoroplastics, polypropylene, nylon; Can certainly be metal-plastic composite material, even can be to make with metal material or other any inorganic material.Sheath can be made by the polyvinyl chloride of low-smoke and flame retardant.
