Connector element for light waveguides

Claim 2

In a connector element for optical fibers, said connector element comprising two carrier members being arranged in alignment with their end faces abutting, each of the carrier members having a plurality of V-shaped centering grooves proceeding parallel to each other and containing said optical fibers, guide channels proceeding on both sides of the centering grooves for receiving guide rails which extend between the two carrier members, a cover plate lying on the optical fibers of the grooves of each member, an adhesive material for mutually fastening the optical fibers, cover plate and respective carrier member together, and an immersion fluid being introduced adjacent the abutting end faces of the members, the improvements comprising means for preventing a flow of both excess adhesive material and immersion fluid into the guide channels, said means for preventing including auxiliary grooves in each of the carrier members extending between the centering grooves and each guide channel, said auxiliary grooves providing collecting surfaces adjacent each side of the centering grooves.

Claim 3

In a connector element according to claim 1, wherein the auxiliary grooves are continuous along the entire length of each of the carrier members.

Claim 4

In a connector element according to claim 1, wherein the auxiliary grooves are composed of sub-grooves.

Claim 5

In a connector element according to claim 1, wherein the auxiliary grooves are aligned sub-grooves formed in each of the carrier members adjacent each side of the centering grooves.

Claim 6

In a connector element according to claim 4, wherein there are at least two sub-grooves on each side, said sub grooves extending to the end face of the carrier member.

Claim 7

In a connector element for optical fibers, said connector element comprising two carrier members having end faces being arranged in alignment with the end faces abutting, each of the carrier members having an upper surface with a plurality of V-shaped centering grooves proceeding parallel to each other and containing said optical fibers, guide channels proceeding on both sides of the centering grooves for receiving guide rails which extend between the two carrier members, a cover plate lying on the optical fibers in the grooves of each member, an adhesive material for mutually fastening the optical fibers, cover plate and respective carrier member together, and an immersion fluid being introduced adjacent the abutting surfaces of the members, the improvements comprising means for preventing a flow of both excess adhesive material and immersion fluid into the guide channels, said means for preventing including collecting surfaces provided adjacent each side of the centering grooves, said collecting surfaces being formed by lateral edges of the cover plate said lateral edges being beveled to proceed outward toward the guide channels in a wedge-shaped fashion from the upper surface of the carrier member.

Claim 8

In a connector element for optical fibers, said connector element comprising two carrier members having end faces being arranged in alignment with the end faces abutting, each of the carrier members having an upper surface with a plurality of V-shaped centering grooves proceeding parallel to each other and containing said optical fibers, guide channels proceeding on both sides of the centering grooves for receiving guide rails which extend between the two carrier members, a cover plate lying on the optical fibers in the grooves of each member, an adhesive material for mutually fastening the optical fibers, cover plate and respective carrier member together, and an immersion fluid being introduced adjacent the abutting surfaces of the members, the improvements comprising means for preventing a flow of both excess adhesive material and immersion fluid into the guide channels, said means for preventing including collecting surfaces provided adjacent each side of the centering grooves, said collecting surfaces being formed by lateral edges of the cover plate said lateral edges being beveled to proceed outward toward the guide channels in a wedge-shaped fashion from the upper surface of the carrier member.

Claim 9

In a connector element according to claim 6, wherein the lateral edges form an acute angle with the upper surface of the carrier member.

Claim 10

In a connector element according to claim 7, wherein said acute angle lies in the range of 30°-45°.

Claim 11

In a connector element according to claim 7, wherein the acute angle is approximately 35°.
