Patent ID: 8625953

Claim:
An optical fiber ribbon holding member that holds a plurality of optical fiber ribbons, in which an optical connector mounted on a substrate is attached at a tip of each optical fiber ribbon, in a laminated state and in a state in which a position of an optical connector at a tip of an optical fiber ribbon is misaligned in a longitudinal direction of a ribbon, and is fixed to a holding member fixture for fixing a holding member that is fixed to a device bedplate on which the substrate is attached, the optical fiber ribbon holding member comprising: a first member that has a base portion having an optical fiber ribbon passing through hole to which a plurality of optical fiber ribbons are passed through in a laminated state, and a pair of upper and lower cantilever shape pinch pieces that are extended from an upper portion and a lower portion of a surface of the base portion that is orthogonal to a passing through direction of an optical fiber ribbon respectively and that pinch an inserted optical fiber ribbon from an upper and lower side; and a second member that has a through hole to which a pair of the pinch pieces is inserted, wherein at least one of a pair of the pinch pieces is a flexible pinch piece; a first surface of the flexible pinch piece at a side for pinching an optical fiber ribbons is a surface parallel with a passing through direction of an optical fiber ribbon, and a second surface at an opposite side to the first surface is a tapered surface in which a thickness of a pinch piece becomes thinner toward a tip of a pinch piece an inner surface of the through hole is a tapered surface to which a tapered surface of the flexible pinch piece is contacted; and a latch structure is provided at the flexible pinch piece and an inner surface of the through hole, and an engaging click and an engaging recess engage to each other when a pinch piece is inserted in a through hole.
