Title
(EN) SHIELDED FLAT CABLE
(FR) CÂBLE PLAT BLINDÉ
(JA) シールドフラットケーブル
Abstract
(EN) This shielded flat cable includes: a plurality of ground lines disposed on a first surface; a pair of signal lines provided between the plurality of ground lines and disposed on the first surface; an insulating layer that covers the plurality of ground lines and the pair of signal lines; and a shield layer that covers the insulating layer, wherein in a cross section perpendicular to the longitudinal direction, the plurality of ground lines include a ground line adjacent to one among the pair of signal lines, and the shortest distance between the pair of signal lines is less than the shortest distance between the adjacent ground line and the one among the signal lines.
(FR) Câble plat blindé comprenant : une pluralité de lignes de masse disposées sur une première surface ; une paire de lignes de signal prévues entre la pluralité de lignes de masse et disposées sur la première surface ; une couche isolante qui recouvre la pluralité de lignes de masse et la paire de lignes de signal ; et une couche de blindage qui recouvre la couche isolante, dans une section transversale perpendiculaire à la direction longitudinale, la pluralité de lignes de masse comprenant une ligne de masse adjacente à une ligne de signal parmi la paire de lignes de signal, et la distance la plus courte entre la paire de lignes de signal étant inférieure à la distance la plus courte entre la ligne de masse adjacente et ladite ligne de signal parmi les lignes de signal.
(JA) シールドフラットケーブルは、第1面に配置された複数のグランド線と、前記複数のグランド線の間に設けられるとともに、前記第1面に配置された一対の信号線と、前記複数のグランド線及び前記一対の信号線を覆う絶縁層と、前記絶縁層を覆うシールド層と、を有し、長手方向に垂直な断面において、前記複数のグランド線は、前記一対の信号線のうちの一方の信号線と隣り合うグランド線を含み、前記一対の信号線の間の最短距離が、前記隣り合うグランド線と前記一方の信号線との間の最短距離よりも小さい。
