Abstract: Proposed is a plug-in connector incorporating an RJ45 connection jack for a data transmission cable (2), said cable being especially a hybrid cable with at least one light transmission conductor (7, 8) and associated therewith also parallel aligned electrical conductors (12). In accord with the invention, the housing contains a connection block (11), which is box-like in shape and which is equipped with at least two openings for the insertion of at least two light conductors (7, 8), one circuit board (18) with connection elements (23) for the joining of the electrical conductor (12) of the hybrid data cable, whereby the circuit board (18) can be mechanically connected to one side of the connection block. The circuit board contains parallel arranged contact paths (19) which are accessible by means of the of open recesses (9) of one of the connection blocks, and the circuit board as well as the given auxiliary casing which surrounds the connection block (11).

Abstract: An aperture, for example a duct having a cable passing through it, is sealed by installing a laminate, comprising an adhesive layer, a heater layer, and a heat-recoverable foam layer, the thickness of which increases on heating, into the gap between the duct wall and the cable with the adhesive layer facing both the wall and the cable. On energizing the heater, the foam increases in thickness and forces the adhesive into sealing engagement with the wall and cable.
