Description

A kind of High-strength compression resistant shielded cable
Technical field
The present invention relates to electrical equipment, more particularly to a kind of High-strength compression resistant shielded cable.
Background technology
Electrical equipment includes primary equipment and secondary device, the secondary device that cable belongs in electrical equipment.With China Economical continues to develop, and the application of cable is more and more wider, its performance requirement also more and more higher.Traditional cable compressive property Weak, anti-electromagnetic wave poor performance has a strong impact on the popularization of cable with using.
The content of the invention
The technical problem existed based on background technology, the present invention proposes a kind of High-strength compression resistant shielded cable, to solve Above-mentioned technical problem.
A kind of High-strength compression resistant shielded cable proposed by the present invention, including:Cable core, aluminium-plastic tape and oversheath;Cable core Including three cores, three elastic resistance to compression cores and binding core, three cores are parallel longitudinal, and abut, on arbitrary section, The line of centres of three cores is in equilateral triangle, and three cores include being located at the conductor at middle part, are coated on successively outside conductor Semiconductive conductor shield, insulating barrier, copper strip shielding layer, elastic cord breaker and lapping layer, elastic resistance to compression core are located at adjacent two Between core, it has the intrados offseted with core, and elastic resistance to compression core cooperates and causes the cable core to have circular cut Face, binding core is located at elastic resistance to compression in-core, and it is formed by many steel wires are stranded, and aluminium-plastic tape is wrapped in the cable core periphery, Oversheath is extruded in aluminium-plastic tape periphery.Binding core is provided with three.On arbitrary section, three binding core lines of centres are in Equilateral triangle.Conductor is formed using many copper wires are stranded.
Elastic resistance to compression core between a kind of High-strength compression resistant shielded cable proposed by the present invention, core makes cable core regular, and The inner space of cable core is taken full advantage of, core stress is not susceptible to movement, effectively prevent the friction between three cores, The occurrence of reducing core abrasion broken string;Elastic resistance to compression core can also be weakened by the elastic deformation of itself to be come from outside cable Stress, improve the compressive property of cable, the binding core set in it makes core be difficult to be destroyed because tearing, and enhances The tensile property of cable;Elastic cord breaker also can weaken the stress entered in conductor by elastic deformation, further improve electricity The compressive property of cable;Using the structure of semiconductive conductor shield, copper strip shielding layer and plastic-aluminum combined layer, cable gear is improved Tool intensity, and make the Distribution of Magnetic Field in cable core uniform, it will not interfere, it effectively eliminates harmonic wave, realize between core The complementation of shielding properties, enhances the overall antijamming capability of cable.High-strength compression resistant shielded cable proposed by the present invention, structure Compact, pressure-resistant tension possesses good electromagnetic wave shielding performance,
Brief description of the drawings
Fig. 1 is a kind of structural representation of High-strength compression resistant shielded cable proposed by the present invention.
Embodiment
As shown in figure 1, Fig. 1 is a kind of structural representation of High-strength compression resistant shielded cable proposed by the present invention.
Reference picture 1, a kind of High-strength compression resistant shielded cable proposed by the present invention, including:Cable core, aluminium-plastic tape 4 and outer Sheath 5;Cable core includes three cores 1, three elastic resistance to compression cores 2 and binding core 3, and three cores 1 are parallel longitudinal, and mutually support Lean on, on arbitrary section, the lines of centres of three cores 1 is in equilateral triangle, three cores 1 include conductor 11 positioned at middle part, Semiconductive conductor shield 12, insulating barrier 13, copper strip shielding layer 14, the and of elastic cord breaker 15 outside conductor 11 are coated on successively Lapping layer 16, specifically, conductor 11 are formed using many copper wires are stranded, and elastic resistance to compression core 2 is located between adjacent both threads core 1, It has the intrados offseted with core 1, and elastic resistance to compression core 2 cooperates and causes the cable core 1 to have circular cross-section, binding Core 3 is located in elastic resistance to compression core 1, and it is formed by many steel wires are stranded, and aluminium-plastic tape 4 is wrapped in the cable core periphery, outer shield Set 5 is extruded in the periphery of aluminium-plastic tape 4.
In this programme, the elastic resistance to compression core 2 between core 1 makes cable core regular, and takes full advantage of the inner space of cable core, The stress of core 1 is not susceptible to movement, effectively prevent the friction between three cores 1, reduce core abrasion broken string situation Generation;Elastic resistance to compression core 2 also can weaken the stress come from inside and outside cable by the elastic deformation of itself, improve cable Compressive property, the binding core 3 set in it makes core 1 be difficult to be destroyed because tearing, and enhances the tensile property of cable;Bullet Property cushion 1 also can by elastic deformation weaken enter the internal stress of conductor 11, further improve the compressive property of cable;Using The structure of semiconductive conductor shield 12, copper strip shielding layer 14 and plastic-aluminum combined layer 4, improves cable machinery intensity, and make Distribution of Magnetic Field in cable core is uniform, will not be interfered between core 1, it effectively eliminates harmonic wave, realize shielding properties Complementation, enhances the overall antijamming capability of cable.
In such scheme, binding core 3 is provided with three, and three binding core 3 lines of centres are in equilateral triangle, are pullled receiving During effect, cable is more uniformly stressed.
High-strength compression resistant shielded cable proposed by the present invention, compact conformation, pressure-resistant tension possesses good electromagnetic wave shielding Performance,
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto, Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
