ABSTRACT:
Apparatus for sealing the entry of an optical cable (11) having an optical fiber (16) into alveolar multicontact connector of the type which comprises an insulating element (1) provided with a plurality of alveoli (2) configured to receive and hold contacts installed at the ends of said cables, and a sealing blanket of an elastically deformable material arranged on one face of the insulating element and having a plurality of passages (7) corresponding in number to the alveoli, each of the passages (7) being aligned with an alveolus, and being elastically extendable in the radial direction during introduction of a cable, characterized in that said apparatus includes a rigid cylindrical coupler (18) mounted with play about the cable (11) and around a part (20) of a contact (10) mounted at the end of the cable, said rigid cylindrical coupler (18) has a length greater than the thickness of the sealing blanket (3) to project beyond the back of the said blanket when said coupler is engaged in the passage (7) of the sealing blanket (3), a socket (25) is mounted about a part (22) of the rigid cylindrical coupler (18) and a part of the cable (11) in back of said rigid cylindrical coupler, said socket (25) forming a complete seal with the cylindrical coupler with its front part (24) and with the cable at its back part (26) and being elastically deformable in its intermediate part (27) between the said front and back parts (24 and 26).
