Connection for two optical fibres - has two rings made of precious stone clamping ends together inside two ferrules

The connection for optical fibres, uses two ferrules (4, 8) enclosing the two fibres (1, 5) which have their sleeving (2, 6) cut back to leave two exposed ends. Each sleeve has a shouldered end, so that the two ends can be clamped together by conventional outer members (19, 20). One ferrule (4) has a counterbore into which is fitted a setting sleeve (13) to hold a ring (14) made from a precious stone, inside which terminates one fibre (1). A similar ring (17) for the end of the other fibre (5) is held inside the projecting top of the sleeve by the second ferrule (8). This ferrule has a bore with a shoulder (16) which clamps the two rings together, with the faces of the fibres in contact. DISPOSITIF DE CONNEXION POUR FIBRES OPTIQUES COMPORTANT UN CHATON 13 DONT UNE PARTIE EST EMMANCHEE DANS L'EMBOUT 12 D'UNE FERULE 4, CONTENANT LA FIBRE OPTIQUE 1, ET DANS LEQUEL EST LOGEE UNE BAGUE 14, DE PREFERENCE EN PIERRE, A TRAVERS LAQUELLE PASSE L'EXTREMITE DE LA FIBRE 1. L'AUTRE PARTIE DU CHATON 13, VIENT SE LOGER AU MOMENT DE L'ASSEMBLAGE, DANS L'EMBOUT 15 D'UNE DEUXIEME FERULE 8, CONTENANT LA FIBRE 5. UN EPAULEMENT 16 MAINTIENT DANS L'EMBOUT 15, UNE SECONDE BAGUE 17 QUI VIENT SE LOGER, AU MOMENT DE L'ASSEMBLAGE DANS LE CHATON 13, EN BUTEE CONTRE LA BAGUE 14.
