Title:
フラットケーブル及びその製造方法
Document Type and Number:
Japanese Patent JP3596348
Kind Code:
B2
Abstract:
In a flat cable including fused portions and twisted pair portions, the length of the twisted pair portions being not constant, the twist pitch of the twisted pair portions being substantially constant independently of the length of the twisted pair portions, some of the twisted pair portions being constituted by S twists with the other twisted pair portions being constituted by Z twists, the next twisted pair portion is twisted in such a manner that, when the number of twists in the S twisted pair portions in the longitudinal direction of the flat cable is added as "plus (+)" value with the number of twists in the Z twisted pair portions being added as "minus (-)" value, the twist sense in the next twisted pair portion is Z twist sense if the integrated value of the number of twists is plus (+) while the twist sense in the next twisted pair portion is S twist sense if the integrated value of the number of twists is minus (-). By virtue of the above constitution, a flat cable with the spacing of fused portions being not constant can be produced without requiring any twist back mechanism.
