Abstract
In said connector, the two fibres 1 to be joined are provided at their ends with a truncated cone-shaped endpiece 2 made of ruby which is encased with clearance in a holding member 3, and the said two endpieces penetrate in a biconical sleeve 4 made of ruby and are held in a connection piece 5. <IMAGE>
Description
SPECIFICATION
Connector for optical fibres
The object of the invention is to join, end to end, two optical fibres with as perfect an axial and radial alignment as possible, without entailing a very accurate production of the mechanical parts of the connector.
A connector for optical fibres is already known which comprises a male cone-shaped part provided with an axial passage through which is threaded the fibre and in which said latter is positioned and finished.
Each end of the fibres which constitutes a cable having been prepared this way, they are then connected to one another by a biconical part having the same low conicity as the ends.
With an appropriate threading provided in the mechanical portion it is possible to make the ends of the cables and the biconical part integral, which also enables, if necessary, a slight rotation of one cable end in the said biconical part, in order to readjust any non-alignment due to possible production defects.
The invention uses this kind of connector, but allows an axial as well as an angular positioning.
It is thus the object of the invention to propose a connector of optical fibres wherein each fibre is provided at its end with a truncated cone-shaped endpiece which fits into a biconical sleeve mounted iri a connection member, wherein the said endpiece is set with some clearance in a holding member which is housed and secured in said connection member.
Other characteristics of the invention will become evident from the following description, given by way of example only and nonrestrictively, reference being made to the accompanying drawing.
The only figure shown in said drawing is an axial cross-section of the connector according to the invention.
As illustrated in the said drawing, the connector according to the invention comprises two optical fibres 1 , the end of each one of which is provided with a truncated cone-shaped endpiece made of ruby, which is encased with a clearance in a holding member 3.
The fibre crosses through the said endpiece 2 axially, and the end portion of said endpiece.
Said endpiece 2 is crossed axially by the fibre and its end portion which is flush with said fibre is rectified, levelled up and polished.
The encasing of the endpiece in the member 3 is produced by a groove 2a provided on the periphery of the endpiece and cooperating with an annular projection 3a of the said member 3.
Upon connection, the two endpieces come into position in a biconical sleeve 4 made of ruby which is held in a connection member 5 which latter receives the endpiece holding members 3.
Said members can be screwed in the connection member 5 or be secured therein by means of a ring screwed on said member 5.
The sleeve 4 whose conicity and concentricity are perfect, is used to align axially the endpiece 2 however small the offset of the members 3.
The clearance willfully left when the ruby 2 is encased in the member 3, allows a slight axial and angular movement of the ruby authorizing the perfect alignment of the fibres 1 when the endpieces penetrate the biconical connection member 5.
The invention is not limited to the embodiment shown or described hereinabove and various modifications may be made thereto without departing from its scope.
1. A connector of optical fibres in which each fibre is provided at its end with a truncated coneshaped end-piece which fits in biconical sleeve mounted in a connection member, wherein the said endpiece is encased with clearance in a holding member which is housed and secured in the said connection member.
2. A connector as claimed in claim 1 , wherein the encasing device consists in a groove provided on the endpiece or on the holding member, and which cooperates with an annular projection on the holding member or on the endpiece.
3. A connector as claimed in claim 1 or 2, wherein the endpieces and the biconical sleeve are made of ruby, the point of the endpiece which is flush with the fibre being levelled up and polished.
4. A connector for optical fibres, substantially as hereinbefore described with reference to, and as illustrated in the accompanying drawing.
