Abstract
The utility model discloses a double-shielding computer cable, which belongs to the technical field of cables. The conductor of the cable adopts a double-layer shielding structure, the surface of the conductor is insulated by crosslinked polyethylene, a PP lapping strip, a plastic-aluminum composite strip inner shielding, a filling, diversion lines, a tin-coated copper wire weaved outer shielding, an inner sheath, a galvanized steel strip armoring and a PVC outer sheath are arranged outside the insulating layer. The cable has the performances of anti-interference, corrosion prevention, resistance to flame, long service life and the like, completely accords with performance demands of double-shielding computer cables, and is applied in control systems with the rated voltage of 300/500 or the lower as a wire of large-scale electric device control, operation and control for none transmission power or transmission operation and control signal control of a plurality of devices and instruments.
Description
Technical field:
The utility model relates to a kind of double layer screen computer cable structure, belongs to the cable new technical field.
Background technology:
Raising day by day along with scientific and technological level, multiple field bus technique has been brought into play advantage in field separately, shown great vitality, fieldbus makes that field instrument and control system and control room have been realized network interconnection and disperseed entirely, the communicating by letter of totally digitilized, intelligent, two-way, multivariable, multiple spot, multistation, having changed 4 ~ 20mA online simulation model standard of traditional utilization, is a change of industrial control system total digitalization.Although DCS has overcome the low defective of simulation model precision in the analogue instrument control system, the deficiency of the antijamming capability of system has had a strong impact on distributed control system architecture, and the efficient and the reliability that increase control system when task will sharply descend.
The double shield computer cable of corporate team's research and development adapts to trend just and produces, it has incomparable superiority, improved the antijamming capability of system, under the high frequency occasion, more can demonstrate its good performance, overcome in the centralized numerical control system controller disposal ability and the high defective of reliability requirement.Have good anti-electric field, magnetic interference performance, and have good anti-core and the jamming performance between the core, be widely used in occasions such as low frequency, high frequency, hyperfrequency.In addition, according to user's needs, my company also can produce special kinds such as flame retardant type, cold resisting type, heat resistant type.Wide use prospect is arranged.
The utility model content:
The purpose of this utility model is to solve the difficult problem that current common computer cable exists, and provides a kind of and has anti-electric field, magnetic interference and have good anti-core and the double layer screen computer cable of jamming performance, Corrosion Protection and control performance between the core.
The purpose of this utility model is to realize like this, a kind of double layer screen computer cable, comprise conductor and the insulating barrier that is extruded in conductive surface, lapping layer, screen, inner sheath, armour and oversheath, it is characterized in that: at the wrapped internal shield of surface of insulating layer, be provided with drainage thread in this screen and constitute single cable, many cables extrude outer shielding layer, inner sheath and oversheath outward successively, are provided with the galvanized steel strip armouring between the inside and outside restrictive coating.
Technology of the present utility model combines with quality material, makes cable that good electric property and physical and mechanical properties be arranged, thereby the anti-interference of cable can be guaranteed.
Above-mentioned conductor is a copper conductor, and skin is provided with double layer screen.Wherein inner shield is an aluminium-plastic tape for dividing the shielding material, and external shield is that total shielding material is the tinned copper wire braiding, and insulating layer material is XLPE, and wrapped belt is PP, and interior jacket material is PVC, and armor material is that galvanized steel strip is between two restrictive coatings.
The utility model is rational in infrastructure simple, and the manufacturing is easy, cost is low.Characteristics such as dielectric loss is little, transmission mark ability is strong, good in anti-interference performance, can transmit faint analog signal reliably, can be widely used in detection and the control computer system or the automation equipment of departments such as generating, metallurgy, oil, chemical industry, light textile, and on the general industrial computer.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, copper conductor, 2, insulating barrier, 3, lapping layer, 4, internal shield, 5, inserts, 6, drainage thread, 7, outer shielding layer, 8, inner sheath, 9, the galvanized steel strip armouring, 10, oversheath.
Embodiment:
As shown in Figure 1, extrude crosslinked polyethylene (XLPE) insulating barrier 2 on the surface of copper conductor 1, adopt the PP band to constitute lapping layer 3 again, lapping layer external application aluminium-plastic tape sub-shield is as internal shield 4, and this screen is outer can insert inserts 5, adopts drainage thread 6 ground connection, add the tinned copper wire braid shielded again as outer shielding layer 7, inner sheath 8 is squeezed on the outer shielding layer surface, uses galvanized steel strip armouring 9 again, extrudes PVC oversheath 10 at last.
