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.
