Patent ID: 7780359

Claim:
A connection structure of a photoelectric flexible wiring board for connecting the photoelectric flexible wiring board to a board using a connector, the photoelectric flexible wiring board transmitting both optical and electrical signals, wherein the connector comprises: a guide hole of U-shape in cross section having a ceiling, a back surface and a surface opposing the ceiling, adapted to receive an end portion of the photoelectric flexible wiring board, with an end of the photoelectric flexible wiring board facing the back surface, a plurality of contacts arranged laterally on the ceiling of the guide hole, and a photonic device provided on the ceiling of the guide hole; the board is mounted with the connector and a driver for the photonic device, the driver being adapted to perform photoelectric conversion; and the photoelectric flexible wiring board comprises: a plurality of electrical transmission lines, arranged laterally on a top surface thereof so as to be contactable directly with the respective contacts on the ceiling of the guide hole, the electrical transmission lines having an entire length substantially equal to an entire length of the photoelectric flexible wiring board, an optical transmission line, provided within the photoeletric flexible wiring board and having an entire length substantially equal to the entire length of the photoelectric flexible wiring board, an optical signal entrance-cum-exit, provided in a surface of an end portion of the optical transmission line so as to face the photonic device, and a waveguide mirror, disposed in an end portion of the optical transmission line so as to face the optical signal entrance-cum-exit, for bending the optical waveguide at a right angle.
