A kind of antijam communication cable that the utility model proposes, comprises cable core, the 3rd lapping layer and screen and insulating barrier;
Cable core comprises locating rack and three holding wires, every root holding wire includes insulator, first signal core and secondary signal core, first signal core is parallel with secondary signal core in the insulator longitudinal, first signal core comprises the first signal body and is coated on the first lapping layer of the first signal external body, secondary signal core comprises secondary signal body and is coated on the second lapping layer of secondary signal external body, locating rack has triangular-section, three holding wires are respectively against side, place, leg-of-mutton three limits, packing material is provided with between every two holding wires, first signal core of every root holding wire and the connecting shaft line of secondary signal core are positioned in cable core radial direction, and the first signal core relative to secondary signal core away from locating rack,
3rd lapping layer is coated on cable core outside, and it is outside that screen is coated on the 3rd lapping layer, and restrictive coating is coated on screen outside.
Preferably, packing material adopts aramid fiber.
Preferably, screen is bimetallic woven shield, and it adopts finer wire and proof copper-wire braided to form.
In the utility model, the antijam communication cable proposed, cable core comprises locating rack and three holding wires, every root holding wire includes insulator, first signal core and secondary signal core, first signal core is parallel with secondary signal core in the insulator longitudinal, locating rack has triangular-section, three holding wires are respectively against side, place, leg-of-mutton three limits, packing material is provided with between every two holding wires, first signal core of every root holding wire and the connecting shaft line of secondary signal core are positioned in cable core radial direction, and the first signal core relative to secondary signal core away from locating rack.In said structure arrangement, on the one hand, in cable core holding wire be symmetrical arranged rationally, Distribution of Magnetic Field is even, and interference free performance is excellent; On the other hand, cable core internal structure is compact and stable, and external force is the position of malleable holding wire in cable core not.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of antijam communication cable that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of antijam communication cable that the utility model proposes.
With reference to Fig. 1, a kind of antijam communication cable that the utility model proposes, comprises cable core, the 3rd lapping layer 4 and screen 5 and insulating barrier 6;
Cable core comprises locating rack 2 and three holding wires, every root holding wire includes insulator 13, first signal core 11 and secondary signal core 12, first signal core 11 is parallel with secondary signal core 12 longitudinal in insulator 13, first signal core 11 comprises the first signal body 111 and is coated on the first lapping layer 112 of external 111 of the first signal, secondary signal core 12 comprises secondary signal body 121 and is coated on the second lapping layer 122 of external 121 of secondary signal, and locating rack 2 has triangular-section;
In the concrete layout of holding wire and locating rack 2, three holding wires are respectively against side, place, locating rack 2 leg-of-mutton three limits, aramid fiber 3 is provided with between every two holding wires, make cable core rounding more, first signal core 11 of every root holding wire and the connecting shaft line of secondary signal core 12 are positioned in cable core radial direction, and the first signal core 11 relative to secondary signal core 12 away from locating rack 2; On the one hand, locating rack 2 and the position of aramid fiber 3 fixed signal line in cable core, not easily move under external force, on the other hand, signal core is circularly and evenly distributed in cable core, and cable core internal magnetic field is evenly distributed, and between holding wire, electromagnetic interference is minimum; Again on the one hand, aramid fiber 3 quality is light and tensile strength is high, can in axis and radial direction guardwire;
3rd lapping layer 4 is coated on cable core outside, tightly be strapped in together by each several part in cable core, screen 5 is bimetallic woven shield, and it adopts finer wire and proof copper-wire braided to form, it is outside that it is coated on the 3rd lapping layer 4, and it is outside that restrictive coating 6 is coated on screen 5; Bimetallic woven shield protects cable core not disturb by external electromagnetic radiation further, and finer wire improves the stretch-proof performance of cable further.
In the present embodiment, the antijam communication cable proposed, cable core comprises locating rack and three holding wires, every root holding wire includes insulator, first signal core and secondary signal core, first signal core is parallel with secondary signal core in the insulator longitudinal, locating rack has triangular-section, three holding wires are respectively against side, place, leg-of-mutton three limits, packing material is provided with between every two holding wires, first signal core of every root holding wire and the connecting shaft line of secondary signal core are positioned in cable core radial direction, and the first signal core relative to secondary signal core away from locating rack.In said structure arrangement, on the one hand, in cable core holding wire be symmetrical arranged rationally, Distribution of Magnetic Field is even, and interference free performance is excellent; On the other hand, cable core internal structure is compact and stable, and external force is the position of malleable holding wire in cable core not.
