A mat sealing joint (28, 28’) for a connector (10), comprising: - a central portion defining at least one passageway (38) extending along a longitudinal direction (X), the passageway (38) being adapted to sealingly receive a wire (36) or fibre, and - a peripheral portion surrounding the central portion and adapted to be sealingly received in a connector housing body (12), wherein the central and peripheral portions are spaced apart from each other and attached to each other only by a closed annular rib extending between an external surface of the central portion and an internal surface of the peripheral portion.

The instant invention relates to mat sealing joints

for connectors, for instance electrical, optical or 5

electro-optical connectors.


Connectors are notably used for connecting an

electrical, optical or electro-optical apparatus to another, and can be found in any kind of electrical,

10 optical or electro-optical devices. Such connectors can, for example, be of the type comprising an electrically insulative housing in which electrical wires or optical fibres are inserted. In this document, an electrical connector is taken as an example, but the person skilled in

20 such foreign bodies. A given class of connectors therefore comprises a so-called mat sealing joint disposed between a housing body (main part of the housing) and a rear grid (rear part of the housing). Sealing is performed peripherally, for example by the sealing joint being

30 joint is relatively high.

       Moreover, due to this high insertion force, substantial damage is caused to the sealing joint, whereby the sealing efficiency of the sealing joint highly decreases after several wire insertion/removal operations.

Besides, conventional mat sealing joints often

comprise silicone, which is an expensive material.

It is an object of the present invention to provide

an improved mat sealing joint with high sealing efficiency 5

and which has a reduced manufacturing cost.

       To this aim, it is provided a mat sealing joint for a connector according to claim 1.

       The mat sealing joint of the present invention can comprise a central portion provided with a plurality of

10 passageways.

       With these features, the central portion of the mat sealing joint of the present invention gains in flexibility with respect to the peripheral portion, thereby reducing the wire insertion force and therefore limiting the risk of

20 also use one or more of the features defined in the claims.

invention will readily appear from the following description of one of its embodiments, provided as a non-
