The first soft elastic sealing member 5 seals the electrical connector 3 in a compressed state. The first soft elastic sealing member 5 is deformed in a compressed state with respect to a relaxed state, and the deformed first soft elastic sealing member 5 tightly surrounds the electrical connector 3 so that the electrical connector is sealed, as shown in fig. 3. Furthermore, the first soft elastic sealing member 5 can be pressed on its edge against the outside of the wall of the housing part 1, so that said wall can be sealed on its outside by the first soft elastic sealing member 5. The first soft elastic sealing member 5 may be made of silicone rubber, for example. The first pressing member 4 can be made of a metal plate, in particular an aluminum plate, for example.
Additionally, the sealing system may further comprise a second soft elastic sealing member 7 which is pressed by the connector holder 2 against the inner side of the wall of the housing part 1 and seals the connector holder 2. The second soft elastic sealing member 7 may be made of silicone rubber, for example.
Additionally, the sealing system may further comprise a second compression member 6 mounted to a side of the connector holder 2 facing away from the wall. The first and second pressing members 4 and 6 may be tensioned. For example, the first and second compression members 4, 6 may be tensioned by means of one or more threaded connections 10. Each threaded connection 10 may have a screw 9 and a threaded sleeve 11, into which sleeve 11 the screw 9 may be screwed. The second pressing member 6 can be made of a metal plate, in particular an aluminum plate, for example.
Fig. 4 is an exploded view of a pre-assembled unit of the sealing system of fig. 1, and fig. 5 is a perspective view of the pre-assembled unit of fig. 4 in an assembled state.
