Abstract

Abstract A connector for light waveguides comprising a housing and at least one clamping member provided in the housing. The clamping member comprises a base having a V-shaped guide groove extending in the longitudinal direction of the housing. The guide groove receives a light waveguide plug. A pressure element is provided opposite the guide groove. The pressure element consists of a clamping bridge and pressure members acting thereon. The height of the pressure members is smaller than the distance between the engaging surface of the clamping bridge and the wall of the housing extending opposite the engaging surface. Screw caps are provided to be screwed laterally on the housing and to act on the pressure members via a pressure piece. The pressure members consist of individual balls which have the same diameter and which are provided in at least one row, one behind the other, in the direction of the longitudinal axis of the housing. The balls are provided within a longitudinal groove of the clamping bridge and/or the wall of the housing.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 341 words
A light-waveguide connector comprising: a housing having a longitudinal axis; a base in the housing, said base having a V-shaped guide groove therein extending in the longitudinal direction, said groove for receiving a light-waveguide plug; a clamping bridge arranged in the housing opposite the guide groove, said clamping bridge having a first side facing the guide groove and a second side opposite the first side, the second side of the clamping bridge and the housing defining a longitudinal groove having a height; a row of balls of uniform diameter arranged between the second side of the clamping bridge and the housing in the longitudinal groove, the diameters of the balls being less than the height of the longitudinal groove; a pressure member arranged between the second side of the clamping bridge and the housing in the longitudinal groove, said pressure member adapted to slide in the longitudinal direction and to bear on the balls; and a screw cap arranged to be screwed on the housing around the longitudinal axis, said screw cap bearing on the pressure member and sliding it in the longitudinal direction; characterized in that: the V-shaped guide groove has an angle bisector which extends through the centers of the balls; the base has a guide section above the guide groove, the guide section having sidewalls which extend parallel to the bisector of the groove; the base has two steps, one on each side of the bisector of the guide groove; the connector further comprises resilient means arranged on each step between the clamping bridge and the base to urge the clamping bridge and the base away from each other; the housing comprises a plurality of clamping assemblies, each clamping assembly comprising a base, a clamping bridge, a row of balls, a pressure member, and a screw cap; and the bases of all of the clamping assemblies are formed of a single common base, the V-shaped guide grooves in the common base being parallel to one another, adjacent V-shaped guide grooves being rotated 180° with respect to each other.
Claim 2
Dependent Claim 341 words
A light-waveguide connector comprising: a housing having a longitudinal axis; a base in the housing, said base having a V-shaped guide groove therein extending in the longitudinal direction, said groove for receiving a light-waveguide plug; a clamping bridge arranged in the housing opposite the guide groove, said clamping bridge having a first side facing the guide groove and a second side opposite the first side, the second side of the clamping bridge and the housing defining a longitudinal groove having a height; a row of balls of uniform diameter arranged between the second side of the clamping bridge and the housing in the longitudinal groove, the diameters of the balls being less than the height of the longitudinal groove; a pressure member arranged between the second side of the clamping bridge and the housing in the longitudinal groove, said pressure member adapted to slide in the longitudinal direction and to bear on the balls; and a screw cap arranged to be screwed on the housing around the longitudinal axis, said screw cap bearing on the pressure member and sliding it in the longitudinal direction; characterized in that: the V-shaped guide groove has an angle bisector which extends through the centers of the balls; the base has a guide section above the guide groove, the guide section having sidewalls which extend parallel to the bisector of the groove; the base has two steps, one on each side of the bisector of the guide groove; the connector further comprises resilient means arranged on each step between the clamping bridge and the base to urge the clamping bridge and the base away from each other; the housing comprises a plurality of clamping assemblies, each clamping assembly comprising a base, a clamping bridge, a row of balls, a pressure member, and a screw cap; and the bases of all of the clamping assemblies are formed of a single common base, the V-shaped guide grooves in the common base being parallel to one another, adjacent V-shaped guide grooves being rotated 180° with respect to each other.
Claim 3
Dependent Claim 21 words
A connector as claimed in claim 1, characterized in that the longitudinal grooves extend in both the base and the housing.
Claim 4
Dependent Claim 23 words
A connector as claimed in claim 2, characterized in that the longitudinal grooves have widths substantially equal to the diameters of the balls.
