Abstract
Abstract A connector element for light waveguides has two carrier members which have guide grooves for the optical fibers and guide channels receiving guide ribs of guide rails for holding the two carrier members in alignment. To prevent possible misalignment due to micro-offsets in the surfaces of the guide channels and ribs of the guide rails or dust particles or the penetration of an immersion material into the guide channel, a portion of the contacting surfaces, either the contacting surface of the guide channel or of the guide rib is removed so that engagement between the rib and channel occurs only at spaced locations.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
134 words
In a connector element for a plurality of light waveguides comprising two carrier members arranged in alignment on a parting plane, each of the carrier members having a plurality of V-shaped centering grooves extending parallel to each other and spaced transversely along the parting plane with the grooves accepting individual optical fibers, each of the carrier members having guide channels on both sides of the centering grooves, and guide rails having matched profile ribs engaged in the channels to align the two carrier members with their V-shaped grooves, the improvement comprising at least the surfaces of one of the channels and the surfaces of the ribs being partially eliminated in sub-regions so that the remaining spaced apart residual surfaces of the channels and ribs form the seating surfaces for the alignment rail and channels.
Claim 2
Dependent Claim
