Abstract
The utility model relates to a broadband cable includes sheath layer, aluminium foil layer, polyester area in proper order from skin to nexine and winds the layer, sets up at the polyester area around intraformational many pairs of line pair, every pair of line pair twist mutually at the insulating layer of conductor periphery by two conductors and cladding and form, still be provided with in the polyester area around the in situ and turn round the skeleton of establishing along the length direction of cable, the adjacent both wings of skeleton between form the recess, the line pair card establish in corresponding recess, owing to adopt the skeleton of turning round mutually and establishing, with the line pair setting in the skeleton recess of turning round establishing, can keep the positional stability of line pair on the one hand, on the other hand can improve the balance characteristic and the crosstalk attenuation of cable, this cable is applicable to high intelligence and public security, government, financial enterprise official working or the higher occasion of management system to the data transmission requirement.
Description
Technical field
The utility model relates to a kind of telecommunication cable.
Background technology
Along with the arrival of information age, the conveying capacity of information becomes explosive growth, and as the effective means of big capacity, long Distance Transmission, cable and optical cable have obtained a large amount of application.Existing broadband cable, as shown in Figure 1, comprise restrictive coating 1 ' successively from skin to nexine, aluminium foil layer 2 ', polyester belt is around layer 3 ', be arranged on the four pair lines of polyester belt in layer 3 ' to 5 ', the every pair of line to 5 ' by two conductors 51 ' and be coated on insulating barrier 52 ' mutually stranded the forming of conductor 51 ' periphery, in described polyester belt 3 ', also be provided with the crossing skeleton 4 ' that extends and be provided with in length and breadth along the cable length direction, form 4 grooves 42 ' altogether between described skeleton 4 ' the adjacent both wings 41 ', described line is fastened in the corresponding grooves 42 ' 5 ', this kind cable skeleton 4 ' structure is more single, be applied in the broadband network, there are bigger cross-talk and noise, thereby influence communication quality, this kind cable is used in broadband network be subjected to certain restriction.
Summary of the invention
Thereby the utility model purpose is to provide a kind of can effectively improve crosstalking of cable in the high-frequency transmission and be more suitable for the cable used in broadband network in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of broadband cable, comprise restrictive coating successively from skin to nexine, aluminium foil layer, polyester belt is around layer, be arranged on described polyester belt how right in layer to line, described every pair of line is to by two conductors and be coated on mutually stranded the forming of insulating barrier of described conductor periphery, in layer, also be provided with along extension of cable length direction and skeleton arranged in a crossed manner at described polyester belt, form groove between the adjacent both wings of described skeleton, described line is to being fastened in the corresponding grooves, and described skeleton is turned round mutually to establish along the length direction of cable and formed.
Described skeleton is turned round shape in the shape of a spiral.
Because technique scheme utilization, the utility model compared with prior art has following advantage: turn round the skeleton of establishing mutually owing to adopt, can effectively offset the STRESS VARIATION that the stranding link produces because of strain, line is turned round in the skeleton groove of establishing being arranged on, but the right positional stability of one side retention wire, can improve the equilibrium response and the crosstalk attenuation of cable on the other hand, in addition, in installation process, the line that can guarantee cable is not destroyed position and structure, it is applicable to high intelligence and public security, government, speech synthesis business datum network and Fast Ethernet and gigabit Ethernet co-existence networks such as financial company's office or management system, can greatly promote the speed and the safety function of broadband network, satisfy the demand of comprehensive wiring product high-end market.
Description of drawings
Accompanying drawing 1 is the cross section view of existing broadband cable;
Accompanying drawing 2 is the cross section view of the utility model broadband cable;
Wherein: 1, restrictive coating; 2, aluminium foil layer; 3, polyester belt is around layer; 4, skeleton; 41, the wing; 42, groove; 5, line is right; 51, conductor; 52, insulating barrier;
Embodiment
Below in conjunction with accompanying drawing, describe particular content of the present utility model in detail for example:
Broadband cable as shown in Figure 2, comprise polyvinyl chloride (PVC) restrictive coating 1 successively from skin to nexine, aluminium foil layer 2, polyester belt is around layer 3, in layer 3, be provided with four lines to 5 at polyester belt, described each line to 5 by two conductors 51 and be coated on insulating barrier 52 mutually stranded the forming of described conductor 51 peripheries, in layer 3, also be provided with along extension of cable length direction and skeleton 4 arranged in a crossed manner at described polyester belt, this skeleton 4 is made by polythene material, and skeleton 4 pretwists are shape in the shape of a spiral, form four grooves 42 between skeleton 4 every adjacent both wings 41, described line is fastened in the corresponding grooves 42 5, by with skeleton 4 pretwists shape in the shape of a spiral, and pitch can be according to different use occasion settings, the bandwidth of this cable can be spreaded to 500MHz, be particularly useful for occasion that transfer of data is had relatively high expectations, as high intelligence and public security, government, the occasion of speech synthesis business datum networks such as financial company's office or management system.
Claims (2)
1. broadband cable, comprise restrictive coating (1) successively from skin to nexine, aluminium foil layer (2), polyester belt is around layer (3), be arranged on a plurality of lines of described polyester belt in layer (3) to (5), described each line to (5) by two conductors (51) and be coated on mutually stranded the forming of insulating barrier (52) of described conductor (51) periphery, in layer (3), also be provided with along extension of cable length direction and skeleton (4) arranged in a crossed manner at described polyester belt, form groove (42) between the adjacent both wings of described skeleton (4) (41), described line is fastened in the corresponding grooves (42) (5), it is characterized in that: described skeleton (4) is turned round mutually to establish along the length direction of cable and is formed.
