Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
A kind of compound access cable as shown in Figure 1; Comprise extexine structure and cable core; Cable core is made up of first, second two pairs of unshielded twisted pairs 2,3 that are used for data communication and the 3rd pair of unshielded twisted pair 4 being used for voice communication; The single line of the single line of first pair of unshielded twisted pair 2 and second pair of unshielded twisted pair 3 near; Folder is established the stranded place of the 3rd pair of unshielded twisted pair 4 between the single line in addition of first pair of unshielded twisted pair 2 and other single line of second pair of unshielded twisted pair 3, and said first, second two pairs of unshielded twisted pairs 2,3 surround the single line of said the 3rd pair of unshielded twisted pair 4.The extexine structure is a PVC sheath 1.Be filled with inserts between PVC sheath and the cable core.The line that first, second two pairs of unshielded twisted pairs 2,3 are radius 0.5mm is right, and the line that the 3rd pair of unshielded twisted pair 4 is radius 0.4mm is right
A. conductor adopts oxygen-free copper bar to make raw material, and after continuous casting and rolling processing, molecular structure is arranged closely, has good electrical property and mechanical performance.Process soft round copper conductor through polyphone line wire drawing and annealing again, electrical property satisfies the regulation of GB/T 3956-1997.
B. the design of insulation thickness: the cable for digital communication SRL better performances that copper content is higher, consider cost factor simultaneously, conductor diameter is selected between the 0.50mm to 0.510, and insulation thickness designs according to conductor diameter again, and the insulation external diameter is 0.91mm.
C. the design of pair twist pitch: for guaranteeing that cross-talk meets the requirements under the high frequency, pair twist group pitch is selected two suitable pitches within 12～22 scopes, could obtain preferable decay and near-end crosstalk.
The stranded design of d cable core: because two pairs 5 types non-shielding pair twist group line stranding lay configuration are stable poor, outward appearance is flat, so stranding increases filling to guarantee construction of cable stability and outward appearance rounding.Technology content and added value of products is high, economic benefit and obvious social benefit.
The utility model adopts two couples of unshielded twisted pair HBYV0.5mm and a pair of HBYV10.4mm; Cable core adds fills stranded stranding; Guarantee cable core structure stability and product appearance, product greatly reduces broadband access medium cost, satisfies the requirement of broadband, speech line simultaneously.Greatly practice thrift production cost, satisfied voice, the broadband demand of communication line to greatest extent, improved the competitiveness of product in market.
This product structure design mainly is the technical performance in order to ensure product:
(1) communication performance meets the regulation of each item index among the YD/T1019-2001 " digital communication is with the horizontal paired cable of solid polyolefin insulation ".
(2) satisfy 100Base-TX communication standard requirement in the Fast Ethernet.
(3) HBYV1 * 2 * 0.4mm line is to satisfying the YD/322-1996 standard.
