Abstract

A sealing element for sealing a cable inserted into a connecting housing, having a passage opening for the cable to pass through, is disk-shaped having at least one first disk having substantially u-shaped circumference, and a second disk having a substantially u-shaped circumference and resting on the first disk. The first disk has two opposite side flanks which extend parallel to each other, and the second disk has a first pair of flanks having two opposite side flanks, which are formed conically with respect to each other. On the top side of the first disk has a sealing lip which is connected to the side flanks respectively via a chamfered connecting region.

First claim

The invention claimed is:

1. A sealing element configured to seal a cable inserted into a connecting housing and having a passage opening configured for the cable to pass therethrough, the sealing element being disc-shaped and comprising:
a first disc having a substantially U-shaped circumference; and
a second disc having a substantially U-shaped circumference and resting on the first disc,
wherein the first disc includes two first opposite side flanks which extend parallel to each other,
wherein the second disc includes a first pair of flanks including two second opposite side flanks, which are formed conically with respect to each other,
wherein the first disc includes, on its upper face connecting the two first opposite side flanks to each other, a sealing lip, the sealing lip being connected to each of the first opposite side flanks via a slanted connecting region.

2. The sealing element of claim 1 , further comprising:
a third disc having a substantially U-shaped circumference,
wherein the third disc has a form corresponding to that of the first disc, and
wherein the third disc is disposed such that the second disc is disposed between the first disc and the third disc.

3. The sealing element of claim 1 , wherein the second disc includes a second pair of flanks including two third opposite side flanks, which are formed conically with respect to each other.

4. The sealing element of claim 1 , wherein the second disc has a planar surface on its upper face connecting the third opposite side flanks to each other.

5. A connecting housing configured for connecting conductors of two or more cables, the connecting housing comprising: a cable feed opening; a lower housing part; and an upper housing part, wherein a first portion of the cable feed opening is formed in the lower housing part, wherein a second portion of the cable feed opening is formed in the upper housing part, wherein the lower housing part has a substantially circumferential rib forming an interior, wherein the rib includes a recess in the region of the cable feed opening, wherein a sealing element formed in one piece and having a passage opening configured a cable to be connected is disposed in the cable feed opening in the recess of the rib, wherein the sealing element includes: a first disc having a substantially U-shaped circumference; and a second disc having a substantially U-shaped circumference and resting on the first disc, wherein the first disc includes two first opposite side flanks which extend parallel to each other, wherein the second disc includes a first pair of flanks including two second opposite side flanks which are formed conically with respect to each other, wherein the first disc includes, on its upper face connecting the two first opposite side flanks to each other, a sealing lip, the sealing lip being connected to each of the first opposite side flanks via a slanted connecting region; wherein the interior formed by the rib is filled with a sealing material, and wherein a flat sealing element is disposed in region of the rib between the lower housing part and the upper housing part.

6. The connecting housing of claim 5 , wherein the flat sealing element at least partially overlaps the sealing element.

7. The connecting housing of claim 5 , wherein a region of the rib which adjoins the cable feed opening, has a slanted edge region.

8. The connecting housing of claim 5 , wherein the rib includes a bifurcation in the region of the cable feed opening.

9. The connecting housing of claim 5 , wherein the lower housing part includes an indentation at a region adjoining the cable feed opening.
