Description

(54) ROTARY CONNECTOR CONNECTING OPTICAL FIBRE CABLES (71) I, FRAN OlS FORT, a French citizen, residing at 42 rue de la Procession, 75015, Paris, France, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement:- The present invention relates to a connector connecting optical fibre cables which connector allows the axial rotation of one cable with respect to the other, such a connector being especially used for connecting the end of one cable wound on a drum, which end is fixed to said drum along the axis of rotation thereof.
According to the present invention there is provided a connector connecting two optical fibre cables, said connector comprising a male portion and a female portion in each of which is mounted an optical fibre cable having only one optical fibre therein, the male portion being rotatable within the female portion via ball bearings interposed between the two portions, and the female portion containing a portion of cable with an optical fibre of cross-section larger than that of the two fibres of said cables, one end of which cable portion abuts an end of said cable mounted in said female portion and the other end of the cable portion abuts an end of said cable mounted in the male portion.
The invention will be readily understood on reading the following description with reference to the accompanying drawings, in which: The single Figure is a schematic view in section of a connector connecting optical fibre cables according to the invention.
Referring now to the drawing, the connector comprises a male portion 1 and a female portion 2, which is the rotary portion fast with the axis of rotation of the drum on which the optical fibre cable 3 is wound.
This fibre cable 3 is mounted in a tube 4, maintained axially in the portion 2 and its end abuts against a cable portion with an optical fibre 5 with a larger cross-section than that of the optical fibre of the cable 3.
This portion of fibre cable 5 is mounted in a tube Sa and is level with the bottom of the female part 2.
The male portion 1, which is fixed, comprises at its end a tube 6 in which is mounted the end of a fibre cable 7 to he connected with the fibre cable 3. The fibre of cable 5 also has a larger cross-section than that of the optical fibre of the cable 7.
This tube 6 slides in the bore of two ball bearings 8 mounted in the female portion 2 and is placed opposite the portion of fibre cable 5 in order that the end of fibre cable 7 may receive the luminous information transmitted by the fibre of the cable 3 through the fibre cable 5.
Due to the size of the cross-section of the fibre of the cable 5 a slight off-centring of the fibre cable 7 with respect to the female portion is of no importance, the end of the fibe cable 7 always remaining completely opposite the fibre of the cable 5 during the rotation of portion 2.
WHAT I CLAIM IS: 1. A connector connecting two optical fibre cables, said connector comprising a male portion and a female portion in each of which is mounted an optical fibre cable having only one optical fibre therein, the male portion being rotatable within the female portion via ball bearings interposed between the two portions, and the female portion containing a portion of cable with an optical fibre of cross-section larger than that of the two fibres of said cables, one end of which cable portion abuts an end of said cable mounted in said female portion and the other end of the cable portion abuts an end of said cable mounted in the male portion.
2. A connector as claimed in claim 1, wherein the male portion comprises at its end a tube in which said cable mounted in the male portion is located, this tube being

2. A connector as claimed in claim 1, wherein the male portion comprises at its end a tube in which said cable mounted in the male portion is located, this tube being positioned and held in the female portion by at least two ball bearings.
3. A connector connecting two optical fibre cables substantially as described hereinabove and illustrated in the accompanying drawing.
