Abstract
A first electrical connector 30 and a second electrical connector 40 are installed on opposed ends of a two-sided flexible printed circuit 50, and the connectors are connected by two layers of conductive patterns. In the intermediate parts 22a and 22b, the conductors 20a of the upper-side circuit pattern and the conductors 20b of the lower-side circuit pattern are arranged so that they extend substantially parallel to each other and are shifted in a pitch direction. Accordingly, electrical connections can be realized in which crosstalk is prevented while a relatively high impedance is maintained; furthermore, the resistance of the FPC 50 to bending is also strengthened.
Claims4
A flexible printed circuit harness device comprising:
- a pair of connectors disposed at opposite ends of a flexible printed circuit, wherein circuit patterns are disposed on both surfaces of the flexible printed circuit, the circuit patterns on each said surface include end portions substantially perpendicular to both ends of said flexible printed circuit and a sloped intermediate portion interconnecting respective inner ends of said circuit patterns at the both end portions, and said circuit patterns on both surfaces of said flexible printed circuit are transversely shifted from an overlapped relationship to an interleaved relationship along the length of said circuit patterns.
