Differential signal transmission cable
View Patent ↗A differential signal transmission cable has four stranded cores, each formed of an inner conductor covered with an insulation of fluorocarbon resin; an outer conductor being spirally wrapped around the four stranded cores in the opposite direction to a stranding direction of the cores; and a sheath formed around the outer conductor, where the diameter of the cable is 1.0 mm or less.
1. A differential signal transmission cable being used in transmitting image signals of liquid crystal displays of mobile phones, comprising:
four stranded cores, each comprising an inner conductor covered with an insulation;
an outer conductor being spirally wrapped around four stranded cores in the opposite direction to a stranding direction of the cores; and
a sheath provided around the outer conductor, where the diameter of the cable is 1.0 mm or less.
2. The differential signal transmission cable according to claim 1 , wherein:
the stranding pitch of said cores is not more than forty times a diameter of a circle formed by connecting centers of the four cores.
3. The differential signal transmission cable according to claim 1 , wherein:
said insulation uses fluorocarbon resin.
4. The differential signal transmission cable according to claim 1 , wherein:
said sheath is made of a fluorocarbon resin or a laminate of a copper-plated polyester tape and a polyester tape.
5. The differential signal transmission cable according to claim 1 , wherein:
when said cores are stranded, polyester filler is located at the center.
