Sealing enclosure for a connector on a cable, such as a standardised fibre-optic connector

The invention relates to a sealing enclosure (1) and a sealing assembly comprising the sealing enclosure (1) and a mating enclosure (62) as well as a method to connect both. The sealing enclosure (1) loosely receives a connector (13) within a connector volume (27) so that the connector (13), which may be of a standard type used in electronic or optic data transmission, may be displaced within a plug face (25) at the forward end of the connector volume (27). Thus, the connector (13) may compensate variations in the position of a mating connector with respect to the mating enclosure (62). Moreover, the sealing enclosure (1) allows sealing off the connector volume (27) and engage the sealing enclosure (1) with a mating enclosure (62) in a single motion. This is effected by having a cable seal (7) interposed between an inner body (3) and an outer body (5). If the outer body (5) is moved forward to engage the mating connector (62), the cable seal (7) is squeezed between the cable (11) and the inner body (3) sealing off the connector volume (27) at the rearward end (21) of the inner body.
