Abstract
The utility model relates to a two-pair digital communication cable which comprises a cable core and a sheath, wherein the cable core is twisted by two filling ropes and two twisted pairs; each twisted pair consists of one pair of twisted conducting wires; the conducting wire consists of a conductor and an insulation layer which coats the conductor; the twisted pairs and the filling ropes are distributed at intervals in the circumferential direction; the diameter of each conductor is 0.5mm-0.51mm; and the outer diameter of each insulation layer is 0.91mm. The two-pair digital communication cable integrally takes the technical property and manufacture cost of products into consider, and adopts two Class 5 non-shielding twisted pairs to satisfy the requirement of Base-TX communication mode in the fast Ethernet; the cable core and the filling ropes are twisted into the cable, so that the structural stability and appearance of the cable core and the stability of technical property of the product can be ensured.
Description
Technical field
The utility model relates to a kind of two pairs of cable for digital communication.
Background technology
Along with the develop rapidly of the computer and the communication technology, people increase considerably the demand of multimedia application such as remote teaching, tele-medicine, video conference, and ecommerce is the typical focus of network application especially.Network application becomes the growing a kind of material progress and cultural and ideological progress demand of people.
Have four pairs and two pairs of cable for digital communication in the market, four pairs of data cable manufacturing cost height have increased the broadband access network cost of access, and actual the use also only is two pairs of lines; And existing two pairs of cable for digital communication only have the line of two pairs of strandings that almost are arranged in parallel, cable core structure instability, communication performance index error.
The utility model content
The purpose of this utility model provides two pairs of stable cable for digital communication of a kind of cable core structure, and satisfies the communication performance index.
For achieving the above object, the utility model adopts following technical scheme: a kind of two pairs of cable for digital communication, comprise cable core and sheath, described cable core is by two gasket for packings and two stranded forming of twisted-pair feeder, described twisted-pair feeder is made up of a pair of stranded lead mutually, described lead is made up of the insulating barrier of conductor and parcel conductor, and described twisted-pair feeder and gasket for packing are along circumferentially spaced apart.
The conductor diameter size range is 0.5mm～0.51mm, and the outside dimension of described insulating barrier is 0.91mm.
Beneficial effect: two pairs of cable for digital communication of the present utility model, take all factors into consideration product technology performance and manufacturing cost, design adopts two pairs 5 class unshielded twisted pairs to satisfy 100Base-TX communication standard requirement in the Fast Ethernet, cable core adds the stranded stranding of gasket for packing, guarantees the structural stability of cable core and the stability of outward appearance and product technology performance.
Consider cost factor, conductor diameter is made as between 0.5mm～0.51mm, and copper content is higher, cable for digital communication SRL better performances.According to the design of conductor diameter size, the corresponding insulation external diameter is made as 0.91mm.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Be illustrated in figure 1 as two pairs of cable for digital communication structural representations of the present utility model, comprise cable core 4 and sheath 7, described cable core 4 is by two gasket for packings 3 and two twisted-pair feeder 6 stranded forming, described twisted-pair feeder 6 is made up of a pair of stranded lead 5 mutually, described lead 5 is made up of the insulating barrier 2 of conductor 1 and parcel conductor, described twisted-pair feeder 6 is circumferentially spaced apart with gasket for packing 3 edges, and conductor 1 diameter dimension scope is 0.5mm～0.51mm, and the outside dimension of described insulating barrier 2 is 0.91mm.
In the design of this cable, require two pairs 5 class unshielded twisted pairs at 100Base-TX communication standard in the Fast Ethernet, to take into account the product operation technique and require and manufacturing cost, the final typical selection structure of confirming is as described below:
Decay is the principal element of decision design of local area network and signal transmission range in cable, and the type of conductor and insulation and physical dimension are the principal elements that influences the decay of data symmetrical cable, mainly pass through to increase insulation thickness or increase the long-pending method reduction of cross-sectional area of conductor to decay in structural design.Facts have proved that the cable for digital communication SRL better performances that copper content is higher is considered cost factor simultaneously, conductor diameter is selected to be increased to 0.510mm from 0.50mm, and insulating barrier 2 thickness design according to this again, and the insulation external diameter is 0.91mm.Cross-talk is an important indicator of circuit transmission quality, and it is the cross-talk that is caused producing voltage and electric current in adjacent lines by electromagnetic field, it with the right pitch of pair twist pitch, laying up pitch and each line than relevant.For guaranteeing that cross-talk meets the requirements under the high frequency, pair twist group pitch is located within 12～22 scopes, could obtain preferable decay and near-end crosstalk.
The insulating barrier 2 of copper conductor outer wrapping layer of polyethylene insulating material of the present utility model, sheath 7 adopts traditional pvc material.Stable poor at the two pairs 5 non-shielding pair twist of class group line stranding lay configuration of tradition, the problem that outward appearance is flat, cable core 4 of the present utility model increases gasket for packing 3 stranded strandings to guarantee construction of cable stability and outward appearance rounding.
Claims (2)
1. two pairs of cable for digital communication, comprise cable core and sheath, it is characterized in that: described cable core is by two gasket for packings and two stranded forming of twisted-pair feeder, described twisted-pair feeder is made up of a pair of stranded lead mutually, described lead is made up of the insulating barrier of conductor and parcel conductor, and described twisted-pair feeder and gasket for packing are along circumferentially spaced apart.
