A coaxial cable including: an inner conductor located at the center portion of the cable; an insulator surrounding the outside of the inner conductor; an outer conductor surrounding the outside of the insulator; and a sheath surrounding the outer conductor, wherein the outer conductor is provided to have a corrugated tube shape having corrugation crests and corrugation troughs formed therein, and wherein an outer diameter 'I' of the insulator, an inner diameter Dof the corrugation crest formed in the outer conductor, and an inner diameter Dof the corrugation trough formed in the outer conductor have the following relationship: and an air layer is formed between the insulator and the corrugation crest of the outer conductor, and a straight line section is provided in the corrugation crest of the outer conductor.

Coaxial cable

A coaxial cable includes a central conductor made of cylindrical conductive material with conductivity greater than 100% and smaller than 104%, the central conductor having a thickness greater than 0.1 mm and smaller than 0.5 mm; a dielectric layer surrounding the central conductor and made of insulating material; an outer conductor surrounding the dielectric layer and made of conductive material with conductivity greater than 97% and smaller than 105% and a thickness greater than 0.24 mm and smaller than 0.35 mm; and an outer jacket surrounding the outer conductor. This coaxial cable allows stable transmission of signal even at a high frequency.

A connector for a coaxial cable physically and electrically connects a coaxial cable with various kinds of electric members. The coaxial cable includes a hollow inner conductor and a corrugated outer conductor surrounding the inner conductor. A carrier terminal inserted into the inner conductor of the coaxial cable has a diameter elastically adjusted to an inner diameter of the inner conductor.

Connector for coaxial cable

A foam coaxial cable includes a central conductor; an inner skin layer surrounding the central conductor coaxially; an insulation layer surrounding the inner skin layer coaxially and made of polyethylene resin containing a plurality of foam cells uniformly formed therein; wherein the inner skin layer is made of polyolefin resin having excellent compatibility with the polyethylene resin to increase an interfacial adhesive force with the insulation layer, an outer skin layer surrounding the insulation layer coaxially to prevent overfoaming of the insulation layer and allow uniform creation of foam cells; a shield surrounding the outer skin layer coaxially; and a jacket surrounding the shield. This cable improves an interfacial adhesive force between the central conductor and the insulation layer and also improves the degree of foam of the foam cells, thereby capable of propagating ultra high frequency of GHz level without signal interference.
