Abstract
Abstract A guide device for a optical filament of a light wave conductor. The device has an inlet opening for receiving the filament. A contact surface is provided in the inlet opening thus forming an installation opening. The contact surface is capable of receiving filaments of different diameters. After the filament of a specified diameter is inserted into the guide device, a hardenable material is filled into the inlet and installation openings and the guide device separated adjacent to the filament end.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
144 words
A guide device for mounting a filament of a light wave conductor, said device having an inlet opening extending along its longitudinal axis from an inlet end for mounting the filament with its filament end in front, the filament being adapted to be fastened in the inlet opening by a fastening device, characterized in that the inlet opening is provided with a contact surface forming an installation opening of varying size shaped to receive filaments of different diameters, said contact surface having along its length at a portion thereof a width less than the diameter of the smallest filament to be mounted by said guide device, and having a shape such that said filament will abut said contact surface at some point along the length of said contact surface in precisely centered relationship relative to said inlet opening when said filament is inserted thereinto.
Claim 2
Dependent Claim
144 words
A guide device for mounting a filament of a light wave conductor, said device having an inlet opening extending along its longitudinal axis from an inlet end for mounting the filament with its filament end in front, the filament being adapted to be fastened in the inlet opening by a fastening device, characterized in that the inlet opening is provided with a contact surface forming an installation opening of varying size shaped to receive filaments of different diameters, said contact surface having along its length at a portion thereof a width less than the diameter of the smallest filament to be mounted by said guide device, and having a shape such that said filament will abut said contact surface at some point along the length of said contact surface in precisely centered relationship relative to said inlet opening when said filament is inserted thereinto.
Claim 3
Dependent Claim
12 words
The guide device of claim 1 wherein the installation opening is cone-shaped.
Claim 4
Dependent Claim
17 words
The guide device of claim 2 wherein the inlet opening is tapered away from the inlet end.
Claim 5
Dependent Claim
14 words
The guide device of claim 3 wherein said inlet opening is tapered in gradations.
Claim 6
Dependent Claim
43 words
The guide device of claim 4 wherein said inlet opening has a truncated cone shape in the direction of the taper and said installation opening has a truncated cone shape, the walls of which are adapted to contact edges of the filament end.
Claim 7
Dependent Claim
15 words
The guide device of claim 5 wherein said device is formed of a plastic material.
Claim 8
Dependent Claim
22 words
The guide device of claim 6 wherein said installation opening terminates at a point, said point being located within said guide device.
Claim 9
Dependent Claim
33 words
The guide device of claim 7 wherein said inlet opening has an outwardly extending first section including a cylindrically shaped opening and an inwardly extending second section which defines said truncated cone shape.
Claim 10
Independent Claim
195 words
A method of mounting filaments of a light wave conductor, comprising: providing a guide device having an inlet opening extending along its longitudinal axis from an inlet end for mounting the filament with its filament end in front, said inlet opening being provided with a contact surface forming an installation opening capable of receiving filaments of different diameters and being of such a shape that when a filament is inserted into said inlet opening, the end of said filament will abut said contact surface at some point along the length of said contact surface in precisely centered relationship relative to said inlet opening when said filament is inserted thereinto, inserting a filament having a specified diameter and a filament end into said inlet opening of said guide device until the filament end contacts said contact surface at a location corresponding to said specified diameter of said filament, filling said inlet opening and said installation opening with a fastening means, and separating said guide device adjacent to said filament end to provide an optical terminating mating end for said conductor whereby said filament is securely held in precisely centered relationship with respect to said guide device.
Claim 11
Independent Claim
195 words
A method of mounting filaments of a light wave conductor, comprising: providing a guide device having an inlet opening extending along its longitudinal axis from an inlet end for mounting the filament with its filament end in front, said inlet opening being provided with a contact surface forming an installation opening capable of receiving filaments of different diameters and being of such a shape that when a filament is inserted into said inlet opening, the end of said filament will abut said contact surface at some point along the length of said contact surface in precisely centered relationship relative to said inlet opening when said filament is inserted thereinto, inserting a filament having a specified diameter and a filament end into said inlet opening of said guide device until the filament end contacts said contact surface at a location corresponding to said specified diameter of said filament, filling said inlet opening and said installation opening with a fastening means, and separating said guide device adjacent to said filament end to provide an optical terminating mating end for said conductor whereby said filament is securely held in precisely centered relationship with respect to said guide device.
Claim 12
Dependent Claim
28 words
The method of claim 9 wherein said fastening means comprises a hardenable sealing compound and including the step of hardening said compound prior to separating said guide device.
Claim 13
Dependent Claim
47 words
The method of claim 10 wherein said guide device is formed of a plastic material, said inlet opening and said installation opening having truncated cone shapes, and wherein said step of separating comprises polishing off the terminal end of the guide material up to said filament end.
Claim 14
Dependent Claim
55 words
The method of claim 11 wherein said contact surface has along its length, said contact surface having along its length a width less than the diameter of the smallest filament to be mounted by said guide device, whereby said filament will abut said contact surface at some point along the length of said contact surface.
Claim 15
Dependent Claim
35 words
The method of claim 10 wherein said filament is provided with a protective outer layer and wherein said sealing compound surrounds said protective layer in the inlet opening and said filament in said installation opening.
