Abstract

The invention relates to a system for sealingly holding cables through an opening. The system comprises a holder substantially in the form of a plate having a central portion with a first thickness between a first side and a second side of the plate and a peripheral portion with a second thickness which is smaller than the first thickness, the holder having in the central portion a plurality of conduits extending in the thickness direction of the plate, each conduit being suitable for having one or more cables extending there through, at least one multi-part sealing plug of an elastic material for sealing an annular space between an inner wall of one of the conduits and a cable extending there through and a gasket of an elastic material and of a shape for placement against the peripheral portion so as to provide a sealing in a circumferential direction of the plate. The plug has at least one circumferentially extending outer rib and at least one circumferentially extending inner rib. In an uninserted state, the following conditions apply: the outer rib has a sawtooth shape for easy insertion, the sawtooth is provided with an angled inward bend for facilitating flexing of the sawtooth in a transverse direction, the inner rib has a top surface extending in circumferential and longitudinal direction for facilitating sliding along the cable, and an imaginary straight line extending in a transverse direction coincides with a pivotal point of the angled bend and intersects the top surface.

Claims

1. System for sealingly holding cables through an opening, the system comprising:

a holder substantially in the form of a plate having a central portion with a first thickness between a first side and a second side of the plate and a peripheral portion with a second thickness which is smaller than the first thickness, the holder having in the central portion a plurality of conduits extending in the thickness direction of the plate, each conduit being suitable for having one or more cables extending there through;

at least one multi-part sealing plug of an elastic material for sealing an annular space between an inner wall of one of the conduits and a cable extending there through, a gasket, of an elastic material and of a shape for placement against the peripheral portion so as to provide a sealing in a circumferential direction of the plate;

wherein the plug has at least one circumferentially extending outer rib and at least one circumferentially extending inner rib, wherein in uninserted state the following conditions apply;

the outer rib has a sawtooth shape for easy insertion, the sawtooth is provided with an angled inward bend for facilitating flexing of the sawtooth in a transverse direction;

the inner rib has a top surface extending in circumferential and longitudinal direction for facilitating sliding along the cable; and

an imaginary straight line extending in a transverse direction coincides with a pivotal point of the angled bend and intersects the top surface.

2. A System according to claim 1, wherein the gasket is of such a combination of hardness and design that in mounted and fixed condition movement of the holder as a result of elastic deformation of the gasket can be accommodated for by the sealing plug without movement of a cable held by the plug relative to contact surfaces between the cable and that plug.

3. A system according to claim 1, wherein the peripheral portion is at least partly flush with the first or the second side.

4. A system according to claim 1, wherein each of the conduits has at one of the first and second side an entrance-opening for sealingly inserting one of the sealing plugs and at the other one of the first and second side a conduit-opening which is smaller than the entrance-opening.

5. System according to claim 1, wherein the peripheral portion is provided with a plurality of through-holes for facilitating fixation of the holder against another holder or against a construction having the opening through which the cables extend, and wherein the gasket has through-holes at positions which correspond to the positions of the through-holes in the peripheral portion of the plate.

6. System according to claim 1, wherein the second thickness is more than 25% of the first thickness, preferably more than 30% of the first thickness.

7. System according to claim 1, wherein each peripheral portion has a width which is in a range of about 3-10% of a total length of the plate.

8. System according to claim 1, wherein all peripheral portions have a similar width.

9. System according to claim 1, wherein a distance between two conduits is 5 mm or less, preferably 3 mm or less.

10. System according to claim 1, wherein the gasket has a maximum thickness of 6 mm, preferably a maximum thickness of 3 mm.

11. System according to claim 1, wherein the gasket has areas of minimum thickness and areas of maximum thickness, wherein the areas of maximum thickness surround the areas of minimum thickness.

12. System according to claim 11, wherein a transition between the areas of minimum thickness and the areas of maximum thickness is stepwise.

13. System according to claim 1, wherein the holder is of a hard engineering plastic material, such as HMPE.
