Abstract
Abstract An arrangement for coupling the ends of optical waveguides includes a housing including at least one first passage for receiving the optical waveguide ends, a second passage for accommodating a plurality of pressing bodies, and at least one slot which extends along an arcuate course between the first and second passages and separates a clamping portion situated between the passages from the remainder of the housing which is constructed as a unitary body. The partial separation of the clamping portion from the remainder of the housing body permits it to resiliently yield to the pressure exerted by the pressing bodies, and thus to clamp the waveguide end in the first passage. A plurality of the first passages may be provided in the housing body around the second passage, each connected with the second passage by an arcuate slot. Another slot may surround the first passage at a distance therefrom. The slots may be formed, subsequent to the provision of the passages, by wire erosion or by electrochemical dissolution of the material of the housing body by an appropriately shaped tool.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
An arrangement for coupling optical waveguide ends mounted in respective connectors, comprising a housing body having at least one first passage dimensioned for receiving the connectors of the optical waveguide ends in an end-to-end alignment, and at least one second passage parallel to and coextensive with said first passage; means for defining in said housing body at least one slot interconnecting said first and second passages and extending along an arcuate course therebetween to partially separate a clamping portion situated between said first and second passages from the remainder of the housing body; and a plurality of pressing bodies accommodated in said second passage and operative for pressing said clamping portion into clamping engagement with the connectors accommodated in said first passage.
Claim 2
Dependent Claim
122 words
An arrangement for coupling optical waveguide ends mounted in respective connectors, comprising a housing body having at least one first passage dimensioned for receiving the connectors of the optical waveguide ends in an end-to-end alignment, and at least one second passage parallel to and coextensive with said first passage; means for defining in said housing body at least one slot interconnecting said first and second passages and extending along an arcuate course therebetween to partially separate a clamping portion situated between said first and second passages from the remainder of the housing body; and a plurality of pressing bodies accommodated in said second passage and operative for pressing said clamping portion into clamping engagement with the connectors accommodated in said first passage.
Claim 3
Dependent Claim
23 words
The coupling arrangement as defined in claim 1, wherein said first passage is substantially cylindrical in conformity with the configurations of the connectors.
Claim 4
Dependent Claim
26 words
The coupling arrangement as defined in claim 1, wherein said slot has several bends between said first and second passages, all oriented in the same sense.
Claim 5
Dependent Claim
54 words
The coupling arrangement as defined in claim 1, wherein said slot has a first section which interconnects said first and second passages and opens into said second passage in a predetermined direction, and a second section forming a continuation of said first section across said second passage therefrom and extending in said predetermined direction.
Claim 6
Dependent Claim
24 words
The coupling arrangement as defined in claim 1, wherein said slot has a section which partially surrounds said first passage at a distance therefrom.
Claim 7
Independent Claim
113 words
A method of manufacturing a housing body of an arrangement for coupling optical waveguide ends mounted in respective connectors, comprising the steps of forming the housing body with at least one first passage for receiving the connectors of the waveguide ends in an end-to-end alignment, and with at least one second passage parallel to and coextensive with the first passage and adapted to receive a plurality of pressing bodies; and subsequently providing in the housing body at least one slot interconnecting the first and second passages and extending along an arcuate course therebetween to partially separate a clamping portion situated between the first and second passages from the remainder of the housing body.
Claim 8
Independent Claim
113 words
A method of manufacturing a housing body of an arrangement for coupling optical waveguide ends mounted in respective connectors, comprising the steps of forming the housing body with at least one first passage for receiving the connectors of the waveguide ends in an end-to-end alignment, and with at least one second passage parallel to and coextensive with the first passage and adapted to receive a plurality of pressing bodies; and subsequently providing in the housing body at least one slot interconnecting the first and second passages and extending along an arcuate course therebetween to partially separate a clamping portion situated between the first and second passages from the remainder of the housing body.
Claim 9
Dependent Claim
14 words
The method as defined in claim 6, wherein said providing step includes wire eroding.
Claim 10
Dependent Claim
38 words
The method as defined in claim 6, wherein said providing step includes electrochemically dissolving the material of the housing body along the arcuate course of the slot by a member having a contour conforming to the arcuate course.
