## Abstract

A cable transit includes an outer frame (10), at least one module-based cable seal, and a final seal which fills-out the frame together with the cable seal. The final seal includes two compressible wedges (11, 12) which can be moved towards an away from each other by a screw (17), and two further compressible wedges (15, 16) which can also be moved towards and away from each other and which coact with the two first wedges. The four wedges are held together by a movable strap (19) which holds the wedges so that they can move relative to one another, wherein the wedges and the screw (17) together form a contained component which can be easily fitted into the frame. The outer side of the flexible strap (19) is provided with guide shoulders (191 to 194) approximately opposite the further wedges (15, 16) for guiding the component to a correct position in the frame. The strap and the wedges are molded in one piece, and one end (51) of the strap is glued to the other end (52) thereof.

## Claims

### Claim 1

A cable transit which comprises an outer frame, at least one module-based cable seal and a final seal which fills-out the frame together with the cable seal and which includes two first compressible wedges which can be moved towards and away from each other by a first screw, and two second compressible wedges which can also be moved towards and away from each other and which coact with the two first wedges, further comprising a flexible strap which holds the first wedges movably in relation to the second wedges, such that the first and second wedges and the first screw form a contained component which can be fitted easily into the frame.

### Claim 2 (depends on 1)

The cable transit according to claim 1, wherein the contained component includes two third wedges which can be moved by a second screw, the third wedges juxtaposed with said first wedges, the two second wedges extendable to enable coaction with the first and third wedges.

### Claim 3 (depends on 1)

The cable transit according to claim 1, wherein the first screw includes two threaded sleeves having a right-hand thread and a left-hand thread respectively, and a long screw having a right-hand thread and a left-hand thread corresponding to the respective threads of the two sleeves, wherein the right-hand thread of the long screw is located distal from a screw head and has a smaller diameter than the left-hand thread of the long screw, which is located proximal to said screw head.

### Claim 4 (depends on 3)

The cable transit according to claim 3, wherein the sleeves are provided with grippers on respective outer sides.

### Claim 5 (depends on 3)

The cable transit according to claim 3, wherein the sleeves are provided with grippers on respective outer sides.

### Claim 6 (depends on 3)

The cable transit according to claim 3, wherein the sleeves are provided with grippers on respective outer sides.

### Claim 7 (depends on 1)

The cable transit according to claim 1, wherein an outer side of the flexible strap is provided with guide shoulders approximately opposite the second wedges, for guiding the contained component to a correct position in the frame.

### Claim 8

A cable transit which comprises an outer frame, at least one module-based cable seal and a final seal which fills-out the frame together with the cable seal and which includes two first compressible wedges which can be moved towards and away from each other by a first screw, and two second compressible wedges which can also be moved towards and away from each other and which coact with the two first wedges, further comprising a flexible strap which holds the first wedges movably in relation to the second wedges, such that the first and second wedges and the first screw form a contained component which can be fitted easily into the frame; wherein the first screw includes two threaded sleeves having a right-hand thread and a left-hand thread respectively, and a long screw having a right-hand thread and a left-hand thread corresponding to the respective threads of the two sleeves, wherein the right-hand thread of the long screw is located distal from a screw head and has a smaller diameter than the left-hand thread of the long screw, which is located proximal to said screw head, wherein the strap draws the two second wedges together at the same time the strap moves the first two wedges apart.

### Claim 9 (depends on 8)

The cable transit according to claim 8, wherein the contained component includes two third wedges which can be moved by a second screw, the third wedges juxtaposed with said first wedges, the two second wedges extendable to enable coaction with the first and third wedges.

### Claim 10 (depends on 8)

The cable transit according to claim 8, wherein an outer side of the flexible strap is provided with guide shoulders approximately opposite the second wedges, for guiding the contained component to a correct position in the frame.

### Claim 11

A cable transit which comprises an outer frame, at least one module-based cable seal and a final seal which fills-out the frame together with the cable seal and which includes two first compressible wedges which can be moved towards and away from each other by a first screw, and two second compressible wedges which can also be moved towards and away from each other and which coact with the two first wedges, further comprising a flexible strap which holds the first wedges movably in relation to the second wedges, such that the first and second wedges and the first screw form a contained components which can be fitted easily into the frame; wherein an outer side of the flexible strap is provided with guide shoulders approximately opposite the second wedges, for guiding the contained component to a correct position in the frame.

### Claim 12 (depends on 11)

The cable transit according to claim 11, wherein the contained component includes two third wedges which can be moved by a second screw, the third wedges juxtaposed with said first wedges, the two second wedges extendable to enable coaction with the first and third wedges.

### Claim 13 (depends on 11)

The cable transit according to claim 11, wherein the first screw includes two threaded sleeves having a right-hand thread and a left-hand thread respectively, and a long screw having a right-hand thread and a left-hand thread corresponding to the respective threads of the two sleeves, wherein the right-hand thread of the long screw is located distal from a screw head and has a smaller diameter than the left-hand thread of the long screw, which is located proximal to said screw head.
