Four pair-twisted shielding wires are twisted to form a pair-twisted shielding wire set; four pair-twisted wires are twisted to form a twisted wire set; two pair-twisted shielding wire sets, two pair-twisted wire sets, ten pair-twisted shielding wires and six three-core twisted shielding sheath wires are twisted to form a cable core; and the outside of the cable core is successively provided with the cable core inner shielding layer, the cable core outer shielding layer and the sheath. The multi-core light-duty shielding control cable has the advantages of light weight and high anti-overhearing interference capability.
Description
Technical field
The utility model relates to a kind of control cables, particularly a kind of being suitable under high frequency as high speed data transfer medium, reliablely and stablely the multicore light shielding control cables of multiplexing sound, data-signal.
Background technology
Common control cables is under high frequency, and the electromagnetic interference between free-throw line pair is stronger, and cross-talk is larger, is unfavorable for the transmitting of control signal.Although the form structure of conventional composite shielding has possessed certain anti-electromagnetic interference capability, in multicore situation, shielding form is larger on aspect impacts such as product weight, physical dimension, flexibilities, thereby can produce larger impact to the use of cable.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provide a kind of have lightweight, under high-frequency anti-cross-talk ability strong, and have simultaneously fire-retardant, electrical insulation capability is high, the multicore light shielding control cables of the feature such as little that decays.
For achieving the above object, the technical scheme of taking is the utility model: a kind of multicore light shielding control cables, is characterized in that: be included in conductor and extrude the insulated wire that a layer insulating forms, two stranded formation twisted pair wires of insulated wire outward; Also be included in described twisted pair wire and weave the pair twist shielding conductor that one deck screen forms outward, also be included in pair twist shielding conductor and extrude the pair twist shield sheath line that sheath forms outward, also comprise that three insulated wires weave successively one deck screen after stranded, extrude the stranded shield sheath line of three cores that sheath forms, and also comprise cable core internal shield, cable core outer shielding layer, flame retardant polyurethane sheath; Four stranded shielding conductor groups of the stranded formation of described pair twist shielding conductor, the four stranded formation twisted wire of described twisted pair wire groups, two groups of stranded shielding conductor groups, two groups of twisted wire groups, ten pair twist shielding conductors, the stranded shield sheath lines of the six roots of sensation three core are twisted into cable core, are provided with successively one deck cable core internal shield, cable core outer shielding layer, sheath outside it.
The beneficial effects of the utility model are: it is crosslinked polyetylene insulated that the applicable thin layer of its insulating barrier employing of multicore light shielding control cables is extruded, screen adopts copper clad aluminum magnesium alloy form, cable core internal shield is the wrapped form of polyester aluminium, cable core outer shielding layer is the form of braiding tin-coated copper, while not only making cable transmit multiple signals under high frequency, there is good anti-electromagnetic interference capability, and reduced weight, guaranteed the flexibility of cable.Sheath adopts the flame resistance polyurethane elastomer extrusion molding with resistance to wear, guarantees when cable is subject to rubbing not fragilely, and has feature fire-retardant, low temperature resistant, that flexibility is good, resistance to wear is good.Lightweight, anti-cross-talk ability is strong in a word.

Embodiment
As shown in Fig. 1,2,3,4,5, multicore light shielding control cables, is included in conductor 1-1 and extrudes the stranded formation twisted pair wire 2 of 1, two insulated wire 1 of insulated wire that a layer insulating 1-2 forms outward; Also be included in the pair twist shielding conductor 4 that the outer braiding one deck of twisted pair wire 2 screen 3 forms, also be included in the outer pair twist shield sheath line 6 of extruding sheath 5 formations of pair twist shielding conductor 4, also comprise that three insulated wires 1 weave successively one deck screen 3 after stranded, extrude the stranded shield sheath line 7 of three cores that sheath 5 forms, and also comprise cable core internal shield 10, cable core outer shielding layer 11, flame retardant polyurethane sheath 12; Four stranded shielding conductor groups 8 of the stranded formation of pair twist shielding conductor 4, the four stranded formation twisted wire of twisted pair wire 2 groups 9, two groups of stranded shielding conductor groups 8, two groups of twisted wire groups 9, ten pair twist shielding conductors 4, the stranded shield sheath lines 7 of the six roots of sensation three core are twisted into cable core, are provided with successively one deck cable core internal shield 10, cable core outer shielding layer 11, sheath 12 outside it.
Insulating barrier 1-2 is crosslinked polyetylene insulated layer.
Cable core internal shield 10 is polyester aluminium lapped shielding layer; Cable core outer shielding layer 11 is tin-coated copper woven shield.
Sheath 12 is flame retardant polyurethane sheath.
Sheath 5 is polyolefin elastomer material.
Cable core is rearranged by more unit wires, reasonable set, has realized multiple signals transmission, and each unit wires, group can independently be transmitted different frequency, dissimilar signal.
Above-mentioned each unit wires, group shield, and have avoided signal cross-talk each other, and this shielding construction has greatly reduced the overall dimension of product, has alleviated product weight, has kept cable flexibility.Cable core internal shield, this compound total shielding form of cable core outer shielding layer can play anti-external electromagnetic signal interference effect well, guarantee the transmitting of inside circuit signal.Sheath adopts the flame resistance polyurethane elastomer extrusion molding with resistance to wear, guarantees when cable is subject to rubbing not fragilely, and has feature fire-retardant, low temperature resistant, that flexibility is good, resistance to wear is good.
