Abstract
The utility model relates to a data cable, which comprises a plurality of twisted pair wires and a sheath. The utility model is characterized in that a baffle is arranged in the sheath and the twisted pair wires are divided into two groups by the baffle. Both ends of the baffle are respectively provided with a supporting board, which forms an H-shaped structure. The top end of the supporting board can be an arc surface. The baffle and the supporting boards are integrally formed. The material can be foamed high/low-density PE as well as other foamed materials having excellent dielectric property and softness. The twisted pair wires are in four pairs and divided into two groups by the baffle, and each group comprises two pairs of twisted pair wires. Because the baffle and the supporting boards are arranged, the consistency of the physical structure of the data cable can be guaranteed, and the contravariance of the physical structure of the data cable is improved. The crosstalk interference resistance, the four-wave attrition, the impedance equilibrium, the ACR and the transmission delay of the data cable are largely enhanced. Therefore, the error rate of data transmission is greatly reduced to enable the performance of the data cable reach the standard.
Description
Technical field
The utility model relates to a kind of data cable, more specifically to a kind of high-speed data cable.
Background technology
Because being extensive use of and it being networked to together needs of personal computer guarantees that the data communication volume of passenger traffic requires the computer network high speed operation.Its velocity interval to surpassing the 1000Mbp30 situation increasing according to data traffic, will need network speed to substantially exceed 1000Mbps from 10Mbps (megabits per second) soon.The increase of network speed also makes the networking designer use whole four pairs of full duplex working cables (all being whole paired cables on the both direction) from using two double duplex cable (each direction is a pair of) to become.This just needs further control in addition and specifies input impedance with minimum signal reflection (return loss).
Standard high-performance data cable structure generally all is to utilize non-shielding multiple twin (UTP) line of four double-twisted structure.Utilize several performance parameters not estimate these data cables.Three important in this evaluation parameters are impedances, decay and crosstalk.
Existing data cable shortcoming is: because four twisted pair wires are direct stranded strandings, relative position between them only depends on the sheath of data cable to be fixed, so data cable is done the time spent being subjected to external force, traction force when for example laying, stretching one extruding force that structure self produced when data cable was crooked 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 four ripple losses, input impedance, near-end crosstalk, multiple parameters deteriorations such as far-end crosstalk.This has seriously limited the operating frequency and the message transmission rate of data cable, also can increase the phenomenon of doing over again in the data cable laid processes simultaneously.
Summary of the invention
At the above-mentioned defective of prior art, the utility model provides a kind of data cable, and the technical scheme of employing is as follows:
Data cable of the present utility model comprises manyly to twisted-pair cable and sheath, and it is characterized in that: be provided with dividing plate in the sheath, dividing plate is separated into two groups with twisted-pair cable.
The two ends of described dividing plate are respectively equipped with a supporting bracket, form " worker " type structure.
For better and sheath cooperate, make the profile of data cable more attractive in appearance, the top of described supporting bracket can be an arc surface.
Described dividing plate and supporting bracket are one-body molded, and its material both can adopt the high/low density PE of foaming, also can adopt other to have the good dielectricity and the expanded material of flexibility.
Described twisted-pair cable has 4 pairs, is separated into 2 groups by dividing plate, 2 pairs every group.
The utility model beneficial effect against existing technologies is, owing to be provided with dividing plate and supporting bracket, therefore can guarantee the consistency of data cable physical structure, improve the antitypy of data cable physical structure, the performance such as harmony, ACR, transmission delay of anti-cross-talk, four ripple losses, the impedance of data cable is improved greatly, thereby reduce the error rate of transfer of data greatly, make the performance of data cable can reach standard.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the diaphragm structure schematic diagram of preferred embodiment shown in Figure 1;
Fig. 3 is the dividing plate cutaway view of preferred embodiment shown in Figure 1.
Embodiment
As Figure 1-3, the data cable in this preferred embodiment comprises 4 pairs of twisted-pair cable 1 and sheath 2, is provided with dividing plate 3 in the sheath.
The two ends of described dividing plate 3 are respectively equipped with a supporting bracket 4, form " worker " type structure, and supporting bracket 4 tops are arc surface, and described dividing plate and supporting bracket are one-body molded, and its material adopts foaming high density PE.
The above only is a preferred embodiment of the present utility model, is not to be used for limiting practical range of the present utility model; Be all equivalents of being done according to claim scope of the present utility model, be the utility model claim scope and cover.
