Abstract

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

Claims5

Dependent claims

A sealing enclosure for a connector on a cable, the sealing enclosure comprising:

a cable seal adapted to sealingly engage the cable;
an inner body comprising a connector volume adapted to receive the connector, the connector volume being open at least at a rearward end and the cable seal being arranged at the rearward end of the connector volume, the inner body at its rearward end being provided with a clamping section, which is adapted to receive the cable seal and which is adapted to be compressed radially about the cable seal;
and
an outer body adapted to slide over the inner body to a forward position, comprising at least one locking element that is adapted to axially secure the sealing enclosure to a mating enclosure when the outer body is in the forward position, the outer body being provided with a wall tapering in the rearward direction, the wall compressing the clamping section around the cable seal;
wherein in the forward position, the outer body extends beyond the cable seal in the rearward direction and the cable seal is compressed by the outer body.
