Diagram 2 is sectional drawings of another embodiment of the present invention.

Embodiment

Cable can use the various combinations of the different conductor of structure, shape, size, material or its combination to constitute.

Referring to Fig. 1, big solid conductor 1 and insulator 2 thereof are formed cable a, and little solid conductor 3 and insulator 4 thereof are formed cable b; Metal forming silk thread (tinsel wire) 5 and insulator 6 thereof are formed cable c, restraint into multicore cable pipe 7 to cable a, b, the c of varying number, size afterwards, and insulator 8 is provided with around the periphery of multicore cable pipe 7; Thereby form multicore cable 9 and 10; Filler composition 11 places the side along multicore cable 9,10, thereby forms multicore compound cable 12, afterwards; Insulator 13 is arranged on around the multicore compound cable 12, thereby accomplishes the cable 14 of the first embodiment of the present invention.

Referring to Fig. 2; The sectional drawing of another embodiment of the present invention, its change be on this invents the basis of first embodiment, comprised in addition one very thin (thin, thin), flat conductor 15; Its cross section is rectangular; After insulator 16 being arranged on around it, become cable, restraint into multicore cable pipe 7 to cable a, b, c and the d of varying number, size afterwards, again insulator 8 is provided with and forms multicore cable 9 and 10 around the periphery of multicore cable pipe 7; Thereby filler composition 11 places the side to form multicore compound cable 12 along multicore cable 9,10; Afterwards, insulator 13 is arranged on around the multicore compound cable 12, thereby accomplishes the cable 14 of the second embodiment of the present invention.

Said conductor is meant any electric conducting material; Conductive filament in certain range of metal is available usually, but also can be made up of any suitable metal material, for example solid copper or stranded copper wire; Copper cover aluminum; Copper cover aluminum/magnesium, and comprise the Metal Substrate coating of silver, aluminium, iron and other metals, and alloy and other different formulations compositions; Conductor also can be the nonmetallic compound with conductivity.Cable can comprise dissimilar conductors.

Conductor can be twisted wire, solid wire, magnet-wire (magnetic wire), metal forming silk thread (tinsel wire) or their combination in any.Conductor can be circular, flat, the diameter of slim profile and different sizes, and in addition, the amount of configuration can be unequal.

As an instance, the cable that uses various different conductors to combine to constitute can comprise any combination of the conductor processed by copper cover aluminum, conductor, twisted copper conductors, solid copper conductor or these conductors that copper cover aluminum/magnesium is processed.Certainly, any combination of these conductors and other conductors also is feasible.

Said insulator also is called as dielectric, is meant the material of cable insulation, such as polyethylene, polypropylene, fluoropolymer, crosslinked polyethylene, rubber and other similar materials; Many insulating materials also comprise the additive more than a type, for example: fire retardant and anti-enzyme agent.

Said big solid conductor 1 is confirmed its physical diameter with little solid conductor 3 through actual test; In the present embodiment, the diameter of big solid conductor 1 is the twice of little conductor 3.

The multicore cable of the embodiment of the invention can be as the transmission alternating current or the signal of telecommunication.This multicore cable can be ac cable, voice-frequency cable, vision cable or any signal of telecommunication cable.The multicore cable of the embodiment of the invention has comprised a plurality of parallel, independent, insulated conductors, and wherein, this cable is thin, light, the most important thing is that ultralow inductance and electric capacity transmit clear and accurate tonequality color.The acoustic characteristic of thin flat conductor comprises abundant, the LF-response closely of clear, high vividness, details, is again the live electric cable of strengthening.In addition, the insulation of each conductor has prevented the interference between different conductor, thereby has avoided the distortion loss of former sound.

When utilizing the combination of different conductors to construct cable, dissimilar conductors is handled specific frequency range respectively, and can be in various utilizations through size, quantity and type combination and optimize and reach best performance.Through using the combination of different conductor type, the type of cable of a uniqueness is invented.Be further optimization, the metal forming silk thread is made up of specific nuclear core and dielectric substance, and it makes the sound decline that causes because of skin effect minimize, and therefore produces better high frequency performance.Because low frequency is offset by the use of metal forming silk thread, solid conductor, so balanced frequency response.Flat conductor is also handled intermediate frequency more accurately.Particularly, the round conductor specification of selection also can be used in bass and treble spectrum, intermediate frequency provided suitable equilibrium.The round conductor of different size shows and focuses on and specific frequency range also can be selected to the graduation frequency equilibrium.Special metal forming silk thread has been given better full range equilibrium and sound quality with the combination of the circular peaceful shape solid conductor of selecting.With the effect that structure the obtained ratio that only constitutes with a kind of conductors, this compound structure is produced superior frequency equilibrium and response accurately.Though this principle is not understood very clearly, seems, dissimilar conductors is had outstanding performance in certain frequency range.Combine through conductor, treble, bass area, district in also having, each all does well, and obtains an outstanding full range cable thus.
