Gel sealing device
The present invention relates to a gel sealing device for sealing a passage of elongate parts through an opening. Such gel sealing device is preferably arranged in a housing used in telecommunication technology. The present invention solves the problem of providing a gel sealing device having improved cable access properties. The inventive gel sealing device comprises a gel sealing block ( 5 ) which provides a sealing section ( 22 ) through which the elongate parts ( 13, 14 ) extend, wherein the gel sealing block ( 5 ) comprises an upper flange ( 11 ) and a lower flange ( 12 ) with a support section ( 11 a, 12 a, 12 b ) disposed therebetween. The upper and lower flanges ( 11, 12 ) sandwiches in direction of extension of the elongate parts ( 13, 14 ), a gel inner ring ( 7 ) supported by said support section ( 2 ) and a gel outer ring ( 6, 10 a ) covering the gel inner ring ( 7 ) in a radial direction extending transverse to said extension direction. The gel inner ring ( 7 ) and the gel outer ring ( 6, 10 a ) are made of a gel sealing material, wherein the sealing section ( 22 ) is formed therebetween. The gel outer ring ( 6, 10 a ) comprises a first circumferential segment ( 6 ) and at least one second circumferential segment ( 10 a ) which is adapted to be detachable from the first circumferential segment ( 6 ) to provide a separate accessible sealing section.
1. A gel sealing device for sealing a passage of elongate parts through an opening, the gel sealing device comprising:
a flange arrangement having a first end and an opposite second end, the flange arrangement having a support section that extends between the first and second ends;
an inner gel seal member that mounts to the flange arrangement at the support section; and
an outer gel seal member that mounts to the flange arrangement over the inner gel seal member, the outer gel seal member and the inner gel seal member cooperating to define a first cable passage having a first size, the outer gel member and the inner gel member sealing the first cable passage when the outer gel member and the inner gel member are compressed by the flange arrangement, the outer gel seal member being removable from the flange arrangement and being separable from the inner gel member, the outer gel seal member including gel disposed between a first member and a second member, the first member defining a first end of the outer gel seal member facing in a first direction away from the gel, and the second member defining a second end of the outer gel seal member facing in a second direction away from the gel, the second direction being opposite to the first direction; and
a first plurality of axial protrusions, each being elongated outwardly in the first direction from the first end of the first member of the outer gel seal member to a respective distal end of the axial protrusion, the distal end of each axial protrusion of the first plurality including a hook configured to latch to the flange arrangement.
2. The gel sealing device of claim 1 , further comprising a second plurality of axial protrusions extending outwardly from the second end of the second member of the outer gel seal member in the second direction, each axial protrusion of the second plurality including a hook configured to latch to the flange arrangement.
3. The gel sealing device of claim 2 , wherein the first plurality of axial protrusions includes two axial protrusions arranged at opposite sides of the first end of the first member of the outer gel seal member; and wherein the second plurality of axial protrusions includes two axial protrusions arranged at opposite sides of the second end of the second member of the outer gel seal member.
4. The gel sealing device of claim 1 , wherein the flange arrangement includes an upper flange that defines the first end of the flange arrangement and a lower flange that defines the second end of the flange arrangement, the upper and lower flanges cooperating to define the support section.
5. The gel sealing device of claim 1 , wherein the support section is recessed relative to outer circumferences of the first and second members of the flange arrangement.
6. The gel sealing device of claim 1 , further comprising a second outer gel seal member that mounts to the flange arrangement at a location circumferentially spaced from the outer gel seal member.
7. The gel sealing device of claim 6 , wherein the second outer gel seal member cooperates with the inner gel seal ring to define a second cable passage having a second size that is different from the first size.
