Description

The invention relates to a sealing device for sealing a cable duct provided for leading through lines, in particular a splice sleeve, wherein the sealing device can be inserted into the cable duct along an insertion axis and has a sealing body made of elastic material which, with respect to a longitudinal axis of the sealing device, is between a first clamping body and a second clamping body of the sealing device is received and has at least one conductor channel for receiving a conductor, in particular an optical waveguide, which can be pushed through the conductor channel along a through axis so that the conductor protrudes in front of opposite end faces of the sealing device, the clamping body being compressed by a clamping device of the sealing body can be adjusted relative to one another from a release position into a clamping position along a clamping axis, the sealing body with respect to d he insertion axis has a smaller outer circumference in the release position than in the tensioned position, so that the sealing device can be displaced in the release position in the cable duct along the insertion axis and tightly closes the cable duct in the tensioned position by placing an outer peripheral surface of the sealing body against an inner peripheral surface of the cable duct in a sealing seat is pressed. The invention also relates to a distributor device with a sealing device of this type.

Splice closures are typically used in harsh environmental conditions, for example in cable ducts and the like. Conductors introduced into the splice closures, which accordingly contain the lightwave cores, must therefore be inserted into the splice closure in a sealed manner, so that the interior thereof is protected from environmental influences, in particular moisture.

The sealing devices have one or more conductor channels through which the conductors are inserted and then fixed by tensioning using the tensioning device. Some of the sealing bodies are laterally slotted so that the conductors can be inserted into the conductor channels of the sealing body from the side. Some sealing bodies can also be opened up, so to speak, i. H. they have two halves that are opened in order to insert the conductors into the conductor channels of the respective sealing body. However, the handling of such sealing bodies is not easy. In particular, there is always the risk that the conductors in the conductor ducts will move out of their desired position, e.g. slip, until the tensioning device is tensioned.

It is therefore the object of the present invention to provide an improved sealing device.

To achieve the object, a sealing device of the type mentioned at the outset has at least one conductor channel of the sealing body at least one constriction contour protruding in the direction of narrowing the conductor channel in this transverse through axis for holding a conductor inserted into the conductor channel in the release position of the clamping device.

To achieve the object, a distributor device, in particular a splice sleeve, is also provided, which has a distributor housing which has a housing base and a housing cover for closing the housing base, so that an interior of the distributor housing is enclosed by the housing base and the housing cover, the distributor housing at least a line lead-through channel for leading lines from the surroundings of the distributor device into the interior of the distributor housing, the distributor device having a sealing device according to the invention.

A basic idea here is that the conductor channel itself has a plug-in cross-section that is optimally suitable for conductors of a predetermined cross-section, but has one or more narrowing contours at one or more points with respect to the longitudinal axis, which, so to speak, already have the conductor in the release position of the clamping device pre-fix, this fixation is then additionally improved by the clamping device. Thus, a fitter can, for example, insert one or more conductors into the sealing body with the tensioning device initially loosened and bring them into a desired position before, by adjusting the tensioning device in the tensioned position, he establishes the final sealing seat and the fixed fixation of the conductors.

A preferred concept provides that the at least one constriction contour has at least one inclined surface with an incline, in particular a conical surface, rising transversely to the insertion axis from an insertion opening of the conductor channel. The inclined surface makes it possible, for example, to introduce the conductor into the conductor channel more conveniently. The conductor can be inserted along the inclined surface up to the smallest cross-section of the conductor channel defined by the narrowing contour. It goes without saying that an inclined surface can only be provided on one side transversely to the through axis of the conductor channel. However, it is preferred if an inclined surface, for example in the manner of a cone, extends around the entire inner circumference of the conductor channel.

It is also advantageous if the at least one constriction contour has an hourglass-like shape. It is therefore also advantageous if the at least one narrowing contour has inclined surfaces which are inclined in opposite directions in relation to the longitudinal axis of the sealing device or the insertion axis of the conductor channel and adjoin one another in the area where they maximally narrow the plug-in cross-section. Rising, inclined inclined surfaces can therefore be provided from opposite end regions or insertion openings of the conductor duct. In cross-section, this results, for example, in an hourglass-like or X-shaped shape of the constriction contour or of the conductor channel. The inclinations of the inclined surfaces are preferably the same.

If the narrowing contour has mutually opposite inclined surfaces which adjoin one another in an apex area, it is preferred if this apex area is rounded and / or runs flat.

It is preferably provided that a plug-in cross-section of the conductor channel in the region of the at least one constriction contour is at least 20%, preferably at least 30%, in particular at least 40% smaller than a maximum plug-in cross-section of the at least one conductor duct at a longitudinal distance with respect to the insertion axis to the at least one constriction contour. Constrictions of the conductor channel of different strengths can therefore be advantageous. This depends, among other things, on how hard the material of the sealing body is. If the material of the sealing body is relatively soft, for example with a Shore A hardness of less than 10, significantly narrower plug-in cross-sections can be provided in the area of the constriction contour than in the case of a greater hardness. A hardness of at least Shore A 15 or more, in particular 20 or 25 Shore A, is preferred.

A preferred concept provides that at least one displacement cavity is provided, in particular between the outer circumferential surface of the sealing body and the line lead-through channel, into which the elastic material of the sealing body can be displaced in the clamping position. In the release position of the clamping device, the displacement cavity is preferably free of the elastic material of the sealing body or not filled with the elastic material of the sealing body. The displacement cavity therefore facilitates the insertion of the conductor into the conductor channel, namely in that the elastic material of the at least one displacement contour can be displaced into the displacement cavity.

It is advantageously provided that the at least one displacement cavity is provided on the sealing body, in particular on its outer circumference when it is not compressed by the clamping device.

However, it is also possible for the displacement cavity to be provided, for example, by a corresponding recess or other cavity on the line lead-through channel in which the sealing device is arranged. There, for example, with respect to the insertion axis in a longitudinal position where the narrowing contour of the sealing device comes to lie, recesses or the like, other recesses, depressions, etc. can be provided as a displacement cavity. It is readily possible for a displacement cavity to be provided both on the cable feed-through channel and on the sealing body, in particular at the same longitudinal position with respect to the insertion axis or the through axis, but also at mutually different longitudinal positions.

It is advantageous if the at least one narrowing contour is arranged in the region of a longitudinal position of the at least one displacement cavity with respect to the longitudinal axis of the sealing device. In any case, a corresponding receiving cavity or displacement cavity is present exactly where the displacement of the elastic material by the conductor inserted into the conductor channel is particularly great.

It is preferably provided that the constriction contour can be displaced by a conductor inserted into the at least one conductor channel in the direction of the at least one displacement cavity, in particular in the release position of the clamping device, and / or is provided and designed for such displacement. Thus, the sealing body gives way, so to speak, in the area of the constriction contour when the conductor is inserted into the conductor channel. Nevertheless, the conductor is held in the conductor channel.

It is also possible, however, for the constriction contour to be supported on the conductor arranged in the conductor channel and for the at least one displacement cavity to be provided and designed so that the elastic material of the sealing body can be displaced into the at least one displacement cavity essentially or only in the clamping position . It is a basic idea that the displacement cavity provides, so to speak, a displacement reserve that is only used when the sealing body is compressed in the clamping position. Thus, for example, pressure on the conductor in the area of the constriction contour is reduced.

At this point, however, it should be emphasized that both are possible, that at least one Displacement cavity provides a receiving space for the elastic material in the area of the constriction contour already in the release position, which is then not yet completely filled with the elastic material, but when the clamping device establishes the clamping position, it is filled with more elastic material than in the release position , for example completely filled or used.

A preferred concept provides that at least one recess for providing the at least one displacement cavity is arranged on the outer circumferential surface of the sealing body, which is in particular designed as a cylinder surface. The sealing body is therefore round, elliptical or oval on the outside in cross section, for example, and essentially forms a cylinder or is essentially cylindrical. Nevertheless, a displacement cavity can be provided on such a cylinder surface.

The recess can be designed, for example, as a step, groove or the like. It is particularly advantageous if the recess is designed in the manner of a trough, in particular a trough which is flat in relation to the longitudinal axis of the sealing device. It is particularly advantageous if a flat trough extends over the entire outer circumference of the sealing body, in particular in the area of the at least one narrowing contour.

It is furthermore advantageously possible for the displacement cavity, in particular the at least one depression, to extend over the entire outer circumference of the sealing body of the sealing body that extends around the longitudinal axis of the sealing device.

However, it is also possible for the at least one displacement cavity to extend over a partial circumference of the sealing body that extends around the longitudinal axis of the sealing device. It is possible for a plurality of displacement cavities, which each extend only over a partial circumference of the sealing body, to be arranged in the same longitudinal position with respect to the through axis of the conductor channel or the longitudinal axis of the sealing body. For example, displacement cavities or depressions can be provided on the outer circumference of the sealing body on opposite sides. However, it is also possible that a displacement cavity or recess is provided on the sealing body on only one side, for example over an angular range of 30-40 °.

A plurality of displacement cavities can be provided in relation to the longitudinal axis of the sealing device or the sealing body. These displacement cavities can each include over the entire outer circumference of the sealing body with respect to the longitudinal axis, or one or more displacement cavities extending over a partial circumference of the sealing body.

It is preferred if the outer circumferential surface of the sealing body is essentially continuous and / or stepless, so that the sealing body in the clamping position has a cylindrical, in particular circular cylindrical, or essentially cylindrical, in particular circular cylindrical, shape over its entire length parallel to the longitudinal axis of the sealing device. Other cylindrical shapes, for example elliptical cylinders or oval cylinders, are also readily possible. It is possible, for example, to provide cylindrical outer circumferential surfaces on the longitudinal end areas of the sealing body with respect to the longitudinal axis of the sealing device or the through axis of the at least one conductor channel, between which there is a constriction in the form is arranged in a shallow trough. The trough is preferably designed in such a way or its depth is provided so that the trough is, so to speak, eliminated by inserting a conductor into the conductor duct or by inserting several conductors into the conductor ducts of the sealing body. H. that a bottom wall of the trough is displaced in the direction of a cylinder diameter of the aforementioned cylindrical outer circumferential surfaces provided on the longitudinal end regions of the sealing body, so that the sealing body already has a substantially cylindrical shape or a completely cylindrical shape on its outer circumference with respect to the longitudinal axis of the sealing device in the release position .

Furthermore, it is possible that the at least one displacement cavity is or includes, for example, a hollow chamber or the like of the sealing body. The hollow chamber is, for example, an air pocket in the sealing body.

It is also advantageous if at least one conductor channel is provided with at least two constriction contours arranged one behind the other with respect to the through axis. The constriction contours can be geometrically the same or different. The plug-in cross-sections defined by the constriction contours can be the same size or different. For example, it is possible for a constriction contour with a larger plug-in cross-section and a constriction contour with a smaller plug-in cross-section to be arranged one behind the other in the insertion direction with respect to the insertion axis.

To provide constriction contours lying one behind the other with respect to the push-through axis, it is possible for the sealing body to be in several parts, for example from a first and a second with respect to the longitudinal axis of the Sealing device arranged next to one another, in particular sealing body parts arranged directly and in contact with one another, is formed or that several, for example two, sealing bodies are provided, each of which provides a constriction contour. This facilitates, for example, the production of a respective sealing body with a casting process or injection molding process.

However, it is also possible and represents a preferred embodiment of the invention that only a single constriction contour is arranged on a respective conductor channel with respect to the through axis.

If the sealing device has a plurality of sealing bodies, these can be arranged directly next to one another with respect to the longitudinal axis of the sealing device, but they can also be spaced apart from one another. It is possible, for example, for a support body, in particular of the type of clamping body explained below, to be arranged between two sealing bodies.

It is advantageously provided that the elastic material of the sealing body has a hardness of at least 10 Shore A.

The hardness is therefore the mechanical resistance of the sealing body which it opposes to the penetration of another body. Depending on the type of action, a distinction is made between different types of hardness. Hardness is not only the resistance against harder bodies, but also against softer and equally hard bodies.

A basic idea here is that the elastic, yet relatively hard sealing body does not, or has less, tendency to shrink or yield over time under the influence of the spring arrangement. The spring arrangement exerts pressure on the sealing body, so that it sits tightly in the cable feed-through channel regardless of the respective ambient temperature and also tightly encloses the at least one conductor accommodated in its at least one conductor channel. The spring arrangement in combination with the relatively hard sealing body, that is to say a sealing body which has a hardness of at least 10 Shore A, therefore ensures optimal tightness of the sealing device. A corresponding tightness can thus be ensured even with high temperature fluctuations and / or high pressure fluctuations. The sealing device remains permanently tight for years regardless of whether the environment is warmer or cooler.

The use of the sealing device is particularly advantageous in the case of splice sleeves or similar other distributor housings that are used in harsh environments. A preferred field of application is the field of optical waveguides or optical waveguide cables.

However, it is also possible to use the sealing device, for example, to seal a cable duct or a cable duct in a building. The building has, for example, a cable duct on an outer wall, in particular in the basement, through which connection lines, for example data lines, gas lines, power supply lines, etc. are to be led. The sealing device can be adapted to the lines to be led through and sealed, d. H. Have conductor channels with matching inner circumferential geometry and push-through cross-sections. It is also possible for the sealing device to be used, for example, in a line bushing of a distribution building which is used to distribute conductors.

In the case of the sealing device, it is advantageously provided that the elastic material of the sealing body has a hardness of at least 15 Shore A, preferably at least 20 Shore A. The correspondingly harder elastic material, which nevertheless still has a high degree of elasticity, is particularly advantageous in the case of greater temperature fluctuations. Accordingly, it can also advantageously be provided that the elastic material of the sealing body has a hardness of at least 25 Shore A, preferably at least 30 Shore A, in particular 35 Shore A.

The hardness of the sealing body is preferably in a range from approx. 15 Shore A to 25 Shore A. A so-to-speak mean hardness of the sealing body of 20 Shore A is preferred.

A preferred concept provides that at least 60%, preferably 70% or 80%, of the elastic material of the sealing body have a hardness of at least 10 Shore A, in particular at least 15 Shore A, preferably at least 20 Shore A, more preferably at least 25 Shore A, having.

The material of the sealing body is preferably a silicone elastomer. Instead of a carbon-polymer chain of typical elastomers, the material of the sealing body preferably comprises silicone-polymer chains, which in particular consist alternately of silicon and oxygen atoms.

It is particularly preferred if the elastic material of the sealing body contains silicone, in particular silicone rubber, for example vinyl silicone rubber (VMQ) or methyl silicone rubber (MVQ). Of course, other elastic materials, for example other types of rubber etc., ethylene propylene diene terpolymer (EPDM), nitrile butadine rubber (NBR), chlorobutadiene rubber (CR), chlorosulfonated polyethylene (CSM), fluorine rubber (FPM or FKM / FFKM), Isobutene-isoprene rubber (IIR) or styrene-butadiene rubber (SBR) can be provided as the elastic material of the sealing body.

Hybrid materials too, i.e. H. for example, sealing bodies made of two different elastic materials are easily possible. However, it is preferred if the sealing body consists of a single elastic material.

In any case, it is possible for the sealing body to have two or more different elastic materials. The different materials can, for example, be arranged in layers one above the other or next to one another. For example, it is conceivable that the materials are arranged linearly one behind the other with respect to the longitudinal axis. A radial, so to speak, shell-like arrangement of the elastic materials is also easily possible. Furthermore, it is possible, for example, for different materials of the sealing body to be arranged next to one another in the linear direction with respect to the longitudinal axis of the sealing device, which materials are also arranged in layers one above the other in the radial direction with respect to the longitudinal axis of the sealing device. The various elastic materials can also be provided, for example, in the form of projections on one elastic material and receptacles on the other elastic material, as mixtures or the like on the sealing body.

There are different possibilities with regard to the design of the clamping body.

It is possible that both clamping bodies are geometrically the same and / or consist of the same materials. It is also possible that one or both clamping bodies have a reinforcement, for example a support body, for example in the form of an insert component, or a support contour made of metal. In particular, if a spring of the sealing device acts directly on the respective support body or the abutments and support bearings to be described of a tensioning anchor of the tensioning device, reinforcement, in particular made of metal, is advantageous.

In general, it should be noted that the clamping bodies advantageously consist of a harder material than the sealing body. Advantageously, there is at least one clamping body, preferably both clamping bodies, made of metal and / or hard plastic and / or fiber-reinforced plastic. Combinations of these materials, for example mixed constructions, d. H. a clamping body, for example made of plastic with a metal reinforcement, are easily possible with a clamping body.

It is preferred if at least one clamping body, preferably both clamping bodies, has at least one passage opening for the conductor that is aligned with the at least one conductor channel of the sealing body. However, it is possible, for example, for one clamping body to have a passage opening which is aligned with a plurality of conductor channels, while another clamping body has a passage opening for one conductor channel in each case.

It is advantageous if the clamping body does not engage or protrude into the conductor channel in the area of the passage opening aligned with the conductor channel of the sealing body with respect to the longitudinal axis of the sealing device and / or does not protrude into the connector cross-section of the conductor channel and / or the inner circumferential contours of the passage opening and the conductor channel next to the Align the passage opening with one another. The clamping body leaves the insertion opening of the conductor duct free, so to speak, and does not act on this insertion opening. For example, the clamping body does not have a funnel-shaped support contour that engages in the conductor channel in the sense of a support.

It is preferred if the sealing body has a funnel-shaped insertion region provided for inserting the conductor, which is arranged directly next to the clamping body with respect to the longitudinal axis of the sealing device. The funnel-shaped shape of the insertion area results, for example, from the narrowing contour. However, it is also possible that, independently of the constriction contour, a funnel-shaped shape of the insertion area is provided for at least one conductor channel.

It is advantageous if a plug-in area provided for plugging in the conductor, for example a funnel-shaped, step-shaped or similar other, plug-in area which is arranged directly next to the clamping body with respect to the longitudinal axis of the sealing device is designed so that the elastic material is exposed on the plug-in area and / or is not stiffened. In particular, the clamping body arranged next to the conductor channel does not act in the sense of supporting the sealing body there. In principle, however, it is possible for a reinforcement separate from the clamping body arranged next to the insertion area to be provided on the insertion area. The stiffening can be provided, for example, by a coating, a cage-like or funnel-like receiving trough or the like. However, the stiffening is not part of the clamping body. The clamping body does not act on the stiffener.

It is advantageously provided that at least one clamping body, preferably both clamping bodies, are plate-like or have plate bodies and / or are supported over a large area on the end faces of the sealing body which run transversely to the clamping axis. Thus, the respective clamping body acts, so to speak, flat on the sealing body, wherein one or more through openings can be provided which are each aligned with a conductor channel. Furthermore, however, the clamping body can also have through openings for clamping anchors of the clamping device.

It is preferred if at least one clamping body has a support projection, in particular designed as a support flange, for supporting with respect to the insertion axis on a, in particular tubular, duct body having the line lead-through duct. The support projection, for example a support flange or annular flange, supports the clamping body on the channel body, for example on an end face of a tubular body or tubular channel body. Thus, supported by the support projection or the plurality of support projections, the sealing device can penetrate into the line lead-through channel with respect to the insertion axis only up to a length defined by the support projection.

Particularly preferred is a form-fitting hold of the sealing device on the line feed-through channel, in particular on a channel body having the line feed-through channel, not only in the longitudinal direction with respect to the insertion axis, but also in the transverse direction to the insertion axis.

It is preferably provided that at least one clamping body has a form-fit receptacle, in particular configured as an annular groove, for form-fit reception of a channel body having the line lead-through channel. The form-fit receptacle is, for example, U-shaped in cross section. The form-fit receptacle is provided, for example, on the aforementioned support projection. This can be designed in the form of a support flange which has an annular groove that is open with respect to the insertion axis or longitudinal axis of the sealing device, the bottom area of which provides the support of the sealing device on the channel body with respect to the insertion axis.

The aforementioned measures make it possible for the sealing device to be supported with respect to the direction of insertion into the channel body or the line lead-through channel, possibly at right angles thereto.

• Vorteilhaft ist vorgesehen, dass ein Spannkörper eine Schraubaufnahme für eine Halteschraube zum Verschrauben der Dichtungsvorrichtung mit einem den Leitungsdurchführungskanal bereitstellenden Kanalkörper aufweist. Anhand der Verschraubung ist es möglich, die Dichtungsvorrichtung mit einer Kraftkomponente, die in Richtung der Einsteckachse wirkt, zugfest und schubfest in dem Leitungsdurchführungskanal zu fixieren.

However, it is also possible that, for example, due to pressure fluctuations in the interior of a distributor housing on which the channel body is arranged, for example in the event of temperature fluctuations, a force acts on the sealing device parallel to the insertion axis and counter to the insertion direction with respect to the insertion axis. For example, a temperature fluctuation in a splice closure can cause a sealing device, so to speak, to be pressed out of the conduit guide channel because the air volume enclosed in the interior space is heated and expands accordingly. The following measure, for example, can help:

• It is advantageously provided that a clamping body has a screw receptacle for a retaining screw for screwing the sealing device to a channel body providing the line lead-through channel. By means of the screw connection, it is possible to fix the sealing device with a force component that acts in the direction of the insertion axis in a tensile and shear-proof manner in the cable feed-through channel.

The retaining screw can for example be screwed transversely to the insertion direction, in particular at right angles to the insertion direction. However, it is advantageously provided that a longitudinal axis of the screw receptacle runs parallel to the insertion axis, so that the retaining screw can be screwed to the channel body parallel to the insertion axis. Thus, for example, front-side operation is possible, i. H. the fitter can screw the retaining screw into the screw receptacle from the same direction in which the conductors, which are to be inserted into, for example, a distributor housing or a splice sleeve.

The housing base of the distributor housing advantageously has a bottom wall and at least one channel body which is arranged on the bottom wall and in which the at least one line lead-through channel to be closed or closed by the sealing device is provided.

The housing cover is preferably designed as a cover hood. The housing base advantageously has a bottom wall which at the same time forms a support base or a base of the distributor housing. The bottom wall is advantageously reinforced by a rib structure.

It is preferably provided that the housing base in front of and / or the housing cover are preferably made of plastic. Fiber-reinforced plastic is particularly advantageous. However, other materials, for example metal or the like, are also readily possible for the housing base or the housing cover. For example, it is also possible that a housing cover consisting of plastic or a housing base consisting of plastic can be replaced by metal, for example a metal plate, metal struts or the like is reinforced.

The housing base and / or the housing cover preferably have reinforcing ribs.

A carrier with holding receptacles for distributor modules is preferably arranged on the housing base. The carrier projects, for example, in the manner of a tower and / or perpendicularly from the bottom wall. The carrier is preferably connected to the rib structure and / or supported on the rib structure.

The holding receptacles preferably form pivot bearings for the distributor modules. The pivot axes of these pivot bearings preferably run parallel to the plane of the bottom wall. The distributor modules are or include, for example, splice cassettes or splice modules. The holding receptacles are preferably arranged next to one another in a row arrangement.

On the carrier, in particular next to the holding receptacles, conductor guide elements, for example cable ducts, holding projections, etc., are preferably provided for guiding conductors between the cable ducts on the bottom wall of the housing base and the distributor modules. A row arrangement of holding receptacles is preferably arranged between row arrangements of conductor guide elements. The row directions of the row arrangements preferably run parallel to one another and / or perpendicular to the plane of the bottom wall.

It is advantageously provided that the spring force of the at least one spring of the spring arrangement can be adjusted using an actuating member, the at least one spring and the actuating member being arranged on opposite sides of the sealing device with respect to the longitudinal axis of the sealing device.

The spring arrangement with the at least one spring is arranged or can be arranged on the side of the line lead-through channel facing the interior of the distributor housing.

Thus, for example, the spring or spring arrangement is arranged as a whole in the interior of a splice sleeve or some other distributor housing, while the actuating element can be actuated from the outside, that is to say is easily accessible. A basic idea here is that the spring or spring arrangement is arranged in a protected manner in the interior of a distributor housing or a splice sleeve, that is to say is protected from contamination as a result. For example, icing in winter can also fundamentally impair the spring function or tensioning function of a spring, but this is not to be feared in the protected interior of the distributor housing or is less likely to occur.

It is advantageous if a channel body of a component accommodating the sealing device, for example a splice sleeve or a distributor housing, has such a length with respect to the insertion axis and / or if the longitudinal extent of the sealing device with respect to its longitudinal axis is dimensioned such that the spring arrangement or the at least one spring does not protrude in front of the channel body and is completely received in the interior of the channel body. In principle, however, it is also possible for the spring or spring arrangement to be received essentially, but not completely, in the channel body or line lead-through channel. For example, at least 10-20%, preferably 30%, in particular at least 40% or 50%, of the longitudinal extension of the spring or spring arrangement with respect to the insertion axis is arranged in the cable duct when the sealing device is mounted in the cable duct.

In the case of the sealing device, it is preferably provided that the at least one spring is supported on one of the clamping bodies. In principle, however, it would also be possible for the spring to be supported directly on a support part of the sealing body, whereby it is advantageous that the sealing body is made of a harder material on the support part or the elastic material is reinforced on the support part, for example by a reinforcement body, a coating or the like.

It is also advantageous if the at least one spring protrudes in front of the clamping body. It is possible that the spring penetrates at least partially into the tensioning body. For example, the clamping body can have a receiving recess for the spring. However, it is advantageous if at least one spring is arranged completely in front of the clamping body with respect to the longitudinal axis of the sealing device and / or does not dip into the clamping body and / or is supported with its end face facing the clamping body on an end face of the clamping body.

A preferred concept provides that the at least one spring is a helical spring which is designed to interact with the sealing body in such a way that it can be adjusted by the actuating member to a maximum preload in which its helical turns rest against one another. A spring force of the spring in the maximally compressed state, that is to say when its screw turns are in contact with one another, and a hardness or a modulus of elasticity of the sealing body are therefore optimal coordinated so that the spring can be adjusted to the maximum preload without damaging the sealing body. This makes assembly particularly easy, because the operator or fitter does not have to measure the spring force to be set, but rather brings the spring to its maximum preload, so to speak, to block it. The pretensioned spring, the coils of which rest on one another, forms a block, so to speak.

The tensioning device can, for example, comprise a tensioning gear with inclined surfaces or wedge surfaces for tensioning the sealing body. It is preferred if the clamping device has at least one clamping anchor which has a support bearing for support on the first clamping body and an abutment for support on the second clamping body, with a clamping distance between the abutment and the clamping device for adjusting the clamping device between the release position and the clamping position Support bearing is adjustable with respect to the clamping axis by means of an actuating means which can be actuated by one or the actuating member. The support bearing and / or the abutment can be formed, for example, by support projections on a bolt section of the tensioning anchor. The support bearing and / or the abutment can support the clamping body directly, e.g. bear directly on the respective clamping body, or also indirectly, e.g. by arranging a support body and / or a spring between the clamping body and the support bearing or abutment.

It is preferred if the at least one tensioning anchor has a bolt section on whose longitudinal end areas, in particular on a screw head of the tensioning anchor on the respective longitudinal end area, the support bearing and / or the abutment are arranged. It can advantageously be provided that the at least one tensioning anchor has at least one screw head on which the abutment or the support bearing are provided or by which the abutment or the support bearing are formed. It is possible for an abutment or support bearing to form a solid, one-piece component of the bolt section, for example in the manner of a head of a nail or the like. But it is also possible that both, namely the abutment and the support bearing, are formed by screw heads.

A preferred concept provides that the at least one tensioning anchor has a tensioning screw which engages in the screw sleeve, screw sections of the tension screw and the screw sleeve providing the adjusting means so that the clamping distance between the abutment and the support bearing can be adjusted by screwing or unscrewing the tension screw into the screw sleeve is. A head of the clamping screw forms, for example, the support bearing or the abutment. A screw head can also be provided on the screw sleeve as an abutment or support bearing or a support projection, in particular a flange projection, which is firmly connected to the screw sleeve or forms an integral part of it. However, it is preferred if the clamping screw on the one hand and a support screw on the other hand are screwed into the screw sleeve on opposite sides, the support screw providing the abutment and in particular supporting a spring that is penetrated by the bolt section.

An advantageous concept provides that the at least one tensioning anchor penetrates the sealing body and / or the first tensioning body and / or the second tensioning body. Thus, the sealing body, which is sandwiched between the two tensioning bodies, can be tensioned by the at least one tensioning anchor.

It is preferred if the screw sleeve penetrates the sealing body. The sealing body can thus slide along the outer circumference of the screw sleeve, in particular when it is compressed or tensioned. In any case, it is preferred if the clamping screw is not in direct contact with the sealing body.

A tensioning screw as part of the tensioning anchor has already been explained. By rotating such a tensioning screw, a torque arises which in principle could lead to the twisting of the tensioning anchor relative to its surroundings. For example, an operator control would be possible in which an operator manually fixes the screw sleeve with a tool or other resistance while screwing in the clamping screw.

However, it is advantageously provided that the at least one tensioning anchor has an anti-rotation contour to hold it securely on the first clamping body and / or on the second clamping body and / or on the sealing body, with an anti-rotation counter-contour on the respective first clamping body or second clamping body or the sealing body Anti-rotation contour of the tension anchor is arranged. The anti-rotation contour can be implemented, for example, by an outer circumferential contour that is polygonal with respect to a longitudinal axis of the tensioning anchor. However, the anti-rotation device is preferably implemented by a bolt element or a support projection which protrudes in front of an outer circumference of the tensioning anchor, in particular its bolt section.

It is advantageous for the anti-rotation counter-contour to have an anti-rotation seat extending parallel to the clamping axis, in FIG which the anti-rotation contour when adjusting the clamping device between the clamping position and the release position is accommodated along the clamping axis so as to be displaceable and secure against rotation. The anti-rotation counter-contour is designed, for example, as a groove that extends in the longitudinal direction, for example of a clamping body or sealing body. When the clamping device is tensioned, the anti-rotation contour plunges into the anti-rotation mount. The anti-rotation lock seat extends advantageously parallel to the tensioning axis of the tensioning anchor. Without further ado, however, a screw-shaped anti-rotation lock receptacle, for example, would also be conceivable, but which has at least one rotary end stop against which the anti-rotation lock contour of the tensioning anchor can strike.

A clamping force that is as uniform as possible on the entire surface of the sealing body to be compressed is preferred. A symmetrical arrangement of the at least one tensioning anchor or several tensioning anchors is therefore advantageous.

It is preferred if the at least one tensioning anchor centrally penetrates the sealing body and the tensioning body with respect to the insertion axis. This embodiment is particularly advantageous when only a single tension anchor is provided.

However, it is also possible for the tensioning device to have several tensioning anchors, for example at least two tensioning anchors, which are arranged next to one another in a row axis that is intersected by the insertion axis or a central longitudinal axis of the sealing device. The insertion axis is provided, for example, centrally in the middle with respect to the cable feed-through channel. The insertion axis corresponds, for example, to a central longitudinal axis of the sealing device.

A preferred concept provides that the at least one spring of the spring arrangement is supported on the one hand on one of the tensioning bodies of the tensioning device and on the other hand on the abutment or support bearing of the tensioning anchor. The spring can thus be tensioned by adjusting the length of the tensioning anchor or shortening it in relation to its longitudinal axis.

The at least one spring is preferably a helical spring, for example. It is advantageously provided that the at least one spring of the spring arrangement is penetrated by the at least one tension anchor. Thus, the spring is supported transversely to its longitudinal axis or tensioning axis on the tensioning anchor, in particular its bolt section.

A preferred concept provides that the at least one spring of the spring arrangement is held in the release position of the tensioning device between the anti-rotation contour of the tensioning anchor and the abutment of the tensioning anchor. When the anti-rotation contour is immersed in the anti-rotation device by tensioning the clamping device or the clamping anchor, the spring is no longer supported on the anti-rotation contour of the clamping anchor, but on the clamping body and applies a clamping force in the direction of the clamping axis. A simple assembly of the spring results, for example, from the fact that it is attached to a bolt section of the tensioning anchor and is supported with one longitudinal end on the anti-rotation contour, for example a transverse bolt penetrating the bolt section transversely, and the other longitudinal end by an abutment or support bearings then attached to the bolt section , for example the head of a screw to be screwed into the bolt section, the screw is supported.

The geometric design of the sealing device advantageously provides that the sealing device has an essentially cylindrical shape on the outer circumferential surface of the sealing body and / or at least one or both clamping bodies. In particular, the sealing device forms an essentially cylindrical structure as a whole, in front of which, for example, one or more springs can protrude. Thus, the sealing device can be plugged into the line lead-through channel in the manner of a cartridge or a sealing module.

For example, a screw to be screwed into the sealing device and a channel body receiving it, or the like, other form-fitting retaining measures, makes it possible to fix the sealing device in the cable feed-through channel, in particular to fix it in a rotationally fixed manner with respect to the insertion axis.

A particularly preferred concept, however, provides that the sealing device has an anti-rotation contour for a non-rotatable hold on or in the line lead-through channel with respect to the insertion axis. The anti-rotation contour as such ensures that the sealing device in the cable feed-through channel cannot be rotated about the insertion axis.

It is advantageously provided that the anti-rotation contour by an angular or non-circular or elliptical or oval cross section and / or by an angular or non-circular or elliptical or oval outer peripheral contour of at least one component of the sealing device, in particular the sealing body and / or at least one clamping body or both clamping bodies, all in the cable duct assembled state of the sealing device is formed in the cable duct engaging components of the sealing device. The sealing device therefore only fits into the cable feed-through channel in predetermined angular positions relative to the insertion axis and cannot be rotated there.

The component receiving the sealing device, for example a distributor housing, in particular a channel body of a distributor housing, advantageously has an anti-rotation counter-contour for holding and / or supporting the sealing device in a rotationally secure manner. The anti-rotation contour and the anti-rotation counter-contour lie against one another when the sealing device is arranged in the line lead-through channel of the component receiving the sealing device.

It can advantageously be provided that at least two sealing bodies are arranged between the clamping bodies with respect to the longitudinal axis, sealing bodies having one or more aligned conductor channels for inserting conductors through the sealing bodies. For example, the sealing bodies consist of different elastic materials and / or have different elasticity or hardness.

Overall, a so-to-speak aligned construction is advantageous. For example, it is advantageous if the insertion axis, along which the sealing device is inserted into the line feed-through duct, and the insertion axis of the at least one conductor duct are parallel to one another. However, it is also possible that, for example, one conductor duct or several conductor ducts run obliquely to the insertion axis, for example with a slight inclination of one degree or 2 degrees or the like, in particular an inclination of a maximum of 10 degrees.

It is readily possible for the sealing device to have only one conductor channel. But it is also possible that the sealing device comprises an arrangement with several conductor channels. The plurality of conductor channels can be arranged asymmetrically or symmetrically with respect to the longitudinal axis or longitudinal center axis of the sealing device. For example, a row arrangement is preferred in which the conductor channels are arranged next to one another along a row axis. However, it is also an annular or circular arrangement of conductor ducts, the multiple conductor ducts being arranged next to one another in a row axis or in a ring, in particular in a circular manner.

A fiber optic distribution box 10 a distribution device 5 has a housing base 11 on that through a housing cover 15th is locked. The housing base 11 has a bottom wall 12th on the one bottom of the distributor housing 11 forms. The distribution device 5 forms a splice closure, for example 6th that can be used in harsh environmental conditions, e.g. cable ducts, etc.

The housing cover 15th is in the form of a cover hood 16 designed. The housing cover 15th has an elongated shape and extends along a longitudinal axis LG of the distributor housing 10 . On a peripheral wall 17th of the housing cover 15th are reinforcing ribs 18th provided that run transversely to the longitudinal axis LG, as well as mutually opposite sides of longitudinal ribs that run parallel to the longitudinal axis and extend up to a top wall 19th of the housing cover 15th extend. The top wall 19th lies on the ground 12th of the distributor housing 11 across from.

The housing cover 15th and the case base 11 delimit an interior space 13th , which is sealed against environmental influences. The interior 13th extends along the longitudinal axis LG between the housing cover 15th and the ground 12th and is circumferentially through the peripheral wall 17th limited.

On opposite and abutting end faces of the housing base 11 and the housing cover 15th is a sealing arrangement 20th intended. For example, the sealing arrangement includes 20th at least one of the housing base 11 in the direction of the housing cover 15th protruding sealing projection 21 and or 22nd . The sealing protrusions 21 , 22nd are ring-shaped. At least one sealing protrusion 21 and or 22nd engages in a seal seat of the housing cover that is not visible in the drawing 15th or is on one end of the housing cover 15th at. It is advantageous between the sealing projections 21 , 22nd a particularly elastic sealing ring 23 , for example an O-ring, arranged, for example in a through a gap between the sealing projections 21 , 22nd formed seal receptacle.

Sealing contours of the sealing arrangement 20th can be done by inserting the housing cover 15th and the housing base 11 parallel to the longitudinal axis LG are brought into engagement with one another to the interior 13th to seal tightly against environmental influences.

The housing base faces radially outwards 11 and the housing cover 15th annular flange projections 14th , 24 before that when the housing base 11 through the housing cover 15th is covered, so this is on the housing base 11 rests, lie opposite one another and, in particular, lie flat against one another.

On opposite end faces of the flange projections 14th , 24 is the sealing arrangement 20th intended. For example, the sealing ring is located 23 on the flange projection 24 at.

The flange protrusions 14th , 24 are by a clamping device 100 held together. The clamping device 100 has a clamping ring 101 on, the one to enclose the distributor housing 10 suitable is. The clamping ring 101 encloses a clamp mount 102 each half of a ring body 103 is limited. The ring bodies 103 are with a swivel bearing 104 pivotally mounted on one another, so that the ring body 103 away from each other and towards each other are pivotable to the clamping receptacle 102 to open or close. For opening or closing the clamping device 100 is a locking device 120 provided by means of a control lever 121 is operable.

From the bottom wall 12th stands in the interior 13th A carrier 25th from where stop shots 26th for distribution modules or distribution cassettes 27 , for example so-called splice cassettes, are arranged. At the holding fixtures 26th are the distribution modules or distribution cassettes 27 preferably pivoted so that they are easily accessible for the assembly of ladders. In 3rd are for example two distributor modules or distributor cassettes 27 shown, which are pivoted away from each other. The distribution cassettes 27 can eg through a tape 25A in one to the carrier 25th be held in the pivoted position.

Next to or on the holding fixtures 26th are preferably conductor guide elements 28 arranged through which a conductor L shown in dashed lines in the drawing can be passed.

The distribution modules 27 have connector plugs, for example 29 on, which can be connected to individual light guides, not shown in the drawing, which are contained in the conductor L. In the connector 29 plugs, not shown in the drawing, can be plugged in, which are also located in the interior of the distribution device 15th running ladders L2 are connected. The ladder L2 form components of so-called patch cables, for example. But it is also possible that in the interior 13th introduced conductors L are or are directly connected to one another, for example by splicing, in particular on a distributor module designed as a splice cassette 27B .

The conductor L as well as other conductors are through the housing base 11 through to the interior 13th guided by the housing base 11 and the housing cover 15th is sealed against environmental influences. In addition, other sealing measures have been taken, which will become clearer below.

In their interior 13th facing side shows the bottom wall 12th a rib structure 12A with one or more ribs 12B , 12C on. The rib structure 12A For example, forms a kind of ribbed lattice, which the bottom wall 12th stiffened. Furthermore, the rib structure carries 12A One Base 25B of the wearer 25th . At the base 25B , especially on the bottom wall 13th facing side of the wearer 25th , hooks or the like are advantageous other holding elements 25C intended for guiding and holding the ladder L.

The one from the interior 13th facing away are on the bottom wall 12th Channel body 30th , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 arranged, which together form a channel body arrangement. The canal bodies 30-39 are tubular and each have a cable duct 40 on. The cable ducts 40 have inner circumferential geometries that depend on the cross section or the inner circumferential geometry of the respective channel body 30-39 depend. Nevertheless, for the sake of simplicity, they are each used as a cable duct 40 designated.

A respective channel body 30-39 has a tubular, substantially more cylindrical circumferential wall 41 on, on their free, from the bottom wall 12th remote side, so a free end area 43 , one end wall each 42 is arranged.

5 shows the case base 11 so to speak in the basic state, ie when the distribution device 5 is not yet equipped with ladders. In this case, namely, the free end faces or end areas 43 on which the end walls 42 are provided, even through the end walls 42 locked.

For equipping, so to speak, cabling, of the distribution device 10 with among other things the ladders L are the end walls 42 from the perimeter walls 41 separated, for example using a schematically shown cutting tool T.

For easier and more precise attachment to a cutting area of the cutting tool T between the respective end wall 42 and the perimeter wall 41 are depressions 44 provided, for example steps. Thus, the cutting tool T can, for example, on the end face of the respective peripheral wall 41 supported along the front wall 42 split off. The cutting tool T is, for example, a cutting tool, a saw, an oscillation tool or the like.

The channel body on the edge, so to speak 30th , 33 , 34 , 37 , 38 and 39 are easily from the outer peripheral area or the outer peripheral area 45 the housing base 11 accessible with the cutting tool T so that the end walls 42 this aforementioned channel body slightly from the tubular body, so the peripheral wall 41 , of the canal body 30th , 33 , 34 , 37 , 38 and 39 can be separated.

But also the, so to speak, central or in a central area 46 the housing base 11 arranged channel body 31 , 32 , 35 , 36 are readily accessible for the parting tool T, namely by their free end regions or end faces 43 in front of the edge channel body 30th , 33 , 34 , 37 , 38 and 39 protrude freely.

The end faces or free end areas 43 the channel body on the edge 30th , 33 , 34 , 37 , 38 and 39 stand for example with a longitudinal distance A1 in front of the bottom wall 12th in front. Opposite are the front sides of the central channel body, so to speak 31 , 32 , 35 , 36 with a longitudinal distance A2 in front of the bottom wall 12th before, which is greater than the longitudinal distance by a difference DA A1 .

The central canal body 31 , 32 , 35 , 36 form a group of a total of 4 channel bodies, each channel body 31 , 32 , 35 , 36 in one, so to speak Corner area of an imaginary rectangle is arranged. Thus every channel body is 31 , 32 , 35 , 36 from the corner area of this imaginary rectangle, so to speak, via an edge-side channel body arranged next to it 30th , 33 , 34 , 37 , 38 and 39 easily accessible away for the cutting tool T.

When the end walls 42 from the canal bodies 30-39 are removed, there is a plug-in cross-section of their respective cable duct 40 for inserting sealing devices 50A , 50B , 50C , 50D freely available.

The sealing devices 50A , 50B , 50C , 50D are functionally similar, which is why they are also generally used as a sealing device in the following description 50 are designated.

The sealing devices 50A , 50B , 50C , 50D differ, for example, with regard to their outer circumferential geometry, the number of conductors through the respective sealing device 50A , 50B , 50C , 50D are feasible through etc., The

Sealing devices 50 can along insertion axes E1 , E2 , E3 , E4 , E5 , E6 , E7 , E8 , E9 in the cable ducts 40 the canal body 30-39 are inserted and then lie close to a respective inner peripheral wall surface 49 of a canal body 30-39 at.

Furthermore, the sealing devices 50 on front sides 48 of the perimeter walls 41 the canal body 30-39 so that these end faces 48 Longitudinal stops with respect to the respective insertion axis E1 , E2 , E3 , E4 , E5 , E6 , E7 , E8 , E9 for the sealing devices 50 provide.

The plug-in axles E1 , E2 , E3 , E4 , E5 , E6 , E7 , E8 , E9 are also referred to as the insertion axis E in the following.

The insertion axes E run parallel to one another, preferably also parallel to the longitudinal axis LG of the distributor housing 10 . Thus, all of the end areas or faces are 43 and accordingly all cable ducts 40 accessible from the same side to conductors, for example the conductor L and other conductors not shown, through the cable ducts 40 through into the interior 13th to introduce the distribution measures there, for example using the distribution modules 27 to realize, for example splicing light guides and connecting them to other light guides.

The front sides 48 of the cable ducts 40 or the perimeter walls 41 support the sealing device 50 with one direction of force K1 parallel to the insertion axis E against a movement in the direction of the interior 13th on the respective cable duct 40 from.

Furthermore are on the front sides 48 of the perimeter walls 41 Screw mounts 47 provided whose screw axes or longitudinal axes run parallel to the respective insertion axis E. For example, are on opposite sides of a respective channel body 30-39 one or a pair of screw mounts 47 intended. The screw mounts 47 are on screw domes 47A provided that radially outwards, ie on the outside of a respective cable duct 40 , in front of the peripheral wall 41 protrude.

The screw domes 47A preferably provide anti-rotation contours for the sealing devices 50 ready the the sealing device 50 in the cable duct 40 against a rotation VD with respect to the insertion axis E held against rotation.

The main function of the screw receptacles 47, however, is that of the screw receptacles 47 screwed in retaining screws 51 the sealing device 50 non-displaceable with respect to the insertion axis E and / or with respect to a direction of force K2 from the interior 13th away in the respective cable duct 40 hold. Preferably hold the retaining screws 51 the sealing device 50 also with regard to the direction of force K1 in their cable duct 40 .

The inner peripheral wall surfaces 49 are counter contours to prevent rotation 49A for securely holding and / or supporting the sealing devices 50 designed with respect to the insertion axis E. The inner peripheral wall surfaces 49 namely have a non-circular, for example elliptical or oval, cross-sectional contour, so that the sealing devices are relative to the inner circumferential wall surfaces 49 cannot rotate about the insertion axes E.

The sealing devices 50A , 50B , 50C , 50D each have pairs of clamping bodies 52A , 53A , 52B , 53B , 52C , 53C , 52D , 53D on, between which a sealing body 54A , 54B , 54C , 54D is arranged. To simplify the following description, the pairings of the clamping bodies are 52A , 53A , 52B , 53B , 52C , 53C , 52D , 53D also as a clamping body 52 , 53 and the sealing body 54A , 54B , 54C , 54D so sealing body 54 referred to, and if the clamping body and sealing body differ geometrically from one another, but functionally have a similar structure.

The clamping body 52 , 53 have push-through openings 55 , 56 for inserting clamping devices 80 , namely tensioning anchors 81 , on. The Through openings 55 , 56 align with push-through openings 57 the sealing body 54 so that the stressing anchor 81 through the aligned push-through openings 55-57 can be pushed through to the clamping body 52 , 53 relative to one another along a clamping axis S, which is parallel to a longitudinal axis LD of a respective sealing device 50 runs to tension. This makes the sandwich-like between the clamping bodies 52 , 53 located sealing body 54 compressed.

The tension anchor 81 have a support bearing at their longitudinal end regions 82 and an abutment 83 on, between which there is a bolt section 84 extends. The bolt section 84 includes screw sleeves 85 , 86 , which are inserted into one another at one of their longitudinal end regions and by means of a transverse bolt 87 are connected to one another and each have a screw receptacle at their opposing, free longitudinal end regions. A longitudinal axis of the cross bolt 87 runs transversely, in particular at right angles, to the clamping axis S. The transverse bolt 87 is, for example, through holes that are aligned with one another 87A the screw sleeves 85 , 86 inserted through and fixed in this, for example pressed or glued.

In the screw sleeve 85 is an abutment screw 88 screwed in, the screw head of which is the abutment 83 provides.

In the screw sleeve 86 is a turnbuckle 89 screwed in, the head of which is an actuator 90 and support bearings 82 provides. At the head of the clamping screw 89 For example, a cross-slot contour or the like other entrainment contour for a tool, in particular a screwdriver, is arranged with which the clamping screw 89 into the screw sleeve 86 Can be screwed in or unscrewed to the clamping device 80 to adjust from a release position to a clamping position and vice versa.

In principle, it would of course be possible that the abutment screw 88 is operated for clamping purposes. In the present embodiment, however, it is provided that the abutment screw 88 basically only screwed once, namely around a spring 91 a spring arrangement 92 between on the one hand the head of the abutment screw 88 and on the other hand the front of the screw sleeves 85 , 86 protruding cross bolt 87 to tension. The feather 91 is from the bolt section 84 interspersed. The feather 91 is for example a coil spring. The feather 91 is so to speak by assembly with the abutment screw 88 on the clamping devices 80 or the tension anchor 81 pre-assembled and / or pre-positioned.

So it is possible that the spring 91 in the release position of the clamping device 80 only or exclusively on the abutment 83 / the head of the abutment screw 88 and the cross bolt 87 supports. However, if the clamping device 80 is adjusted from its release position into the clamping position, namely by the clamping screw 89 into the screw sleeve 86 is screwed in, the spring is supported 91 at that of the spring 91 facing front side 58 of the clamping body 53 from. The feather 91 namely stands in front of the front 58 in front and cannot go into the push-through opening 57 of the clamping body 53 immerse, but is based on the outer edge area of the push-through opening 57 from.

The cross bolt 87 can be placed in an anti-twist device 59 of the clamping body 53 immerse that extends from the end face 58 away along the through opening 57 in the direction of the sealing body 54 extends. So if the clamping screw 89 based on the actuator 90 (of your head) into the screw sleeve 85 is screwed in, the cross bolt emerges 87 increasingly in the anti-rotation device 59 one while the spring 91 not in the push-through opening 57 can immerse. Then the spring is supported 91 no longer on the cross bolt 87 off, but on the front side 58 of the clamping body 53 .

At the other longitudinal end area of the clamping device 80 the head of the tensioning screw acts 89 , namely the support bearing 82 on the free face 60 of the clamping body 52 by the sealing body 54 is turned away so that the sealing body 54 sandwich-like by tensioning the clamping device 80 is compressed, the spring force of the spring 91 in the sense of tensioning or compressing on the sealing body 54 works.

Across the bolt section 84 protruding sections of the cross bolt 87 form anti-rotation contours 93 located in the anti-rotation device 59 of the clamping body 53 can't twist. The anti-rotation device 59 thus forms an anti-rotation counter contour 61 . The anti-rotation device 59 is designed, for example, as a receiving groove extending parallel to the clamping axis S, into the free end regions of the transverse bolt 87 immerse or intervene and support yourself on the side walls.

By adjusting the clamping device 80 from the release position to the clamping position is the distance between the clamping bodies 52 , 53 downsized, making the sealing body 54 is compressed in relation to the clamping axis S. This will make its outer circumference 62 radially outward to the inner peripheral wall surface 49 of the respective cable duct 40 pressed or displaced, whereby the sealing body 54 in the sealing seat on the inner circumference of the cable duct 40 is applied.

Interlocking screw sections of the screw sleeve 85 and the tensioning screw 89 form an adjusting means 94 the clamping device 80 .

It is advantageous that the screw sleeve 85 has such a longitudinal extent that it has the sealing body 54 completely penetrated in relation to the longitudinal axis LD, so that the screw contours of the clamping screw 89 not in contact with the push-through opening or the clamping channel 56 of the sealing body 54 got. This is the sealing body 54 on the outer circumference of the screw sleeve 85 Slightly movable with respect to the clamping axis S.

So that the sealing device 50 in the cable duct 40 cannot twist, the sealing body has 54 an outer peripheral surface 62 with a non-circular outer circumferential contour, namely, for example, with an oval or elliptical outer circumferential contour, the surface with the corresponding oval or elliptical inner circumferential contour of the inner circumferential wall 49 with respect to the insertion axis E can come into engagement against rotation. Thus it forms the outer circumferential surface 62 an anti-rotation contour 63 .

Also the clamping body 52 , 53 have on their outer circumferences or outer circumferential surfaces that are parallel to the longitudinal axis LD of the sealing body 50 run, the anti-rotation contour 63 on. The clamping bodies 52, 53 are of the same shape as the outer circumferential surface 62 in that area of the outer peripheral surface 62 , which is directly on the clamping body 52 , 53 in relation to the longitudinal axis LD of the sealing body 54 adjoins. There are both the clamping bodies 52 , 53 as well as that of the sealing body 54 cylindrical, but not circular cylindrical, but for example oval-cylindrical or elliptical-cylindrical. Without further ado, however, other non-circular or non-circular outer circumferential contours of the clamping body would also be 52 , 53 and / or the sealing body 54 , for example polygonal outer circumferential contours possible, those with corresponding and form-fitting matching inner circumferential contours of the inner circumferential wall surface 49 each one with respect to the insertion axis E or longitudinal axis LD anti-twist retention of the sealing body 50 in the cable duct 40 enable.

At this point it should be mentioned that for a secure hold of the sealing device 50 with respect to the insertion axis E in the cable duct 40 also only one anti-rotation contour 63 on one of the bodies 52 , 53 or 54 would be enough.

Thus, a form fit of the sealing body ensures 54 and / or the clamping body 52 and or 53 on the inner peripheral wall surface 49 for a secure hold with respect to the insertion axis E, during the frictional engagement of the sealing body 54 on the inner peripheral wall surface 49 for a frictional hold of the sealing body 54 and thus the sealing device 50 as a whole in the cable duct 40 ..

A plug-in path of the sealing device 50 in the cable duct 40 in along the insertion axis E is, as mentioned, through the end face 48 the outer peripheral wall 41 limited, namely a support projection 64 in the form of a flange in front of the clamping body 52 protrudes radially outward with respect to the insertion axis E, strikes. The supporting protrusion 64 is ring-shaped.

On the support protrusion 64 are screw mounts 65 for the retaining screw 51 intended. The screw mounts 65 are for example through openings. When the sealing device 50 in the cable duct 40 is inserted and the support projection 64 at the front 48 strikes, aligned screw mounts 65 with the screw mounts 47 on the canal bodies 30-39 . The longitudinal axes of the screw mounts 47 and the screw mounts 65 run parallel to the insertion axis E. Thus, the retaining screw 51 in a screwing direction parallel to the insertion axis E into the screw receptacles 65 , 47 be plugged in or screwed in, so that they the sealing device 50 with directions of force parallel to the insertion axis E on the cable duct 40 fix.

For a fixation and centering transversely to the insertion axis E is on the support projection 64 a form fit recording 66 in the form of, for example, an annular groove, provided in which the peripheral wall 41 intervenes. The form-fit recording 66 includes, for example, a peripheral wall 67 around the outer peripheral surface of the clamping body 52 extends around and has a radial distance to this, so that the form-fit receptacle 66 is designed, for example, in the manner of a U-shaped receptacle, at the bottom of which the end face 48 the perimeter wall 41 of the canal body 30-39 can strike.

In the area of the screw domes 47A has the perimeter wall 67 preferably expansion games 68 . The screw domes 47A in connection with the expansion games 68 provide a further anti-twist device for the sealing device 50 relative to the cable duct 40 with respect to the insertion axis E.

The assembly of the sealing device 50 succeeds accordingly simply and effectively: the sealing device 50 is in the respective Cable duct 40 inserted and with the retaining screws 51 with the respective canal body 30-39 screwed so that the sealing device 50 with respect to the insertion axis E, both twist-proof and shift-proof in the cable feed-through channel 40 is recorded. The retaining screws 51 are conveniently operated by, so to speak, from the front, ie from the free side of the bottom wall 12th are operable.

From this side, from which also the conductor L to the distributor housing 10 lead, so are the actuators 90 the clamping devices 80 operable. Apart from the ladders L, there are no components hindering the actuation or assembly in the way.

In particular, the spring assemblies 92 in the interior 13th the distribution device 5 or the distributor housing 10 arranged. So you are not facing the outside of the distributor housing 10 before where to assemble the distribution device 5 would be a hindrance when equipping with conductors L or the like. Rather, the spring arrangements are 92 protected in the interior 13th arranged so that they do not get dirty, do not freeze in the cold or the like, what their spring function or tensioning function with respect to the sealing body 54 could affect in principle.

Furthermore, the spring assemblies 92 at least partially in the cable ducts 40 , also in the spaces between the ribs 12B , 12C the rib structure 12A arranged. Just a short part of the respective nib 91 stands in front of the rib structure 12A in front. In practice, however, this is not a problem, because namely the conductors L at least in the area of the spring arrangements 92 approximately parallel to the longitudinal extensions of the springs 91 or the clamping devices 80 run away.

Depending on the required tension force or spring force, the sealing devices 50A-50D one or more clamping devices 80 intended. The clamping devices are preferred 80 symmetrically arranged, for example with the sealing device 50A along a major axis of the elliptical cross section of the sealing device 50A , roughly corresponding to the section line BB in 8th , or at the sealing device 50B along the section line DD in 15th . Even with the sealing device 50D are the clamping devices 80 arranged symmetrically, but along a minor axis of the elliptical cross section of the sealing device 50D . At the sealing device 50C however, there is only a single, centrally arranged clamping device 80 intended.

Due to the different design of the sealing devices 50A-50D is an individual equipping of the distribution device 5 with ladders L, namely ladders of different cross-sections, different numbers, etc. possible.

The seal body 54A-54D the sealing devices 50A-50D have conductor channels 70A-70D to accommodate ladders L, which in through the ladder channels 70A-70D pushed through state passage openings 69 the clamping body 52 , 53 penetrate and in front of the respective end faces of the sealing devices 50A-50D protrude.

This is the case with the sealing device, for example 50A only a single conductor channel 70A provided, ie by the sealing device 50A can only be a single conductor along a through axis DA of the conductor channel 70A be pushed through. This takes place in the release position of the clamping devices 80 , namely when the seal body 54 the sealing device 50A is not compressed, so that a plug-in cross-section of the conductor channel 70A not by the compression of the sealing body 50 is narrowed. At the sealing device 50B however, there are 2 conductor channels 70B provided, through each of which a conductor L can be inserted, but a conductor that has a smaller cross section than a conductor that passes through the conductor channel 70B can be pushed through.

At the sealing device 50C are conductor channels 70C provided, through each of which a conductor L along the respective through axis DA of the conductor channel 70C can be pushed through. The conductor channels 70C have even smaller connector cross-sections than the conductor ducts 70B . The conductor channels 70C are, for example, ring-shaped around the clamping device 80 arranged around each other.

At the sealing device 50D are conductor channels 70D provided, for example, two conductor channels 70D , the opposite sides of the clamping devices 80 along a series axis which is the major axis of the elliptical cross-section of the sealing device 50D corresponds, are arranged. The conductor channels 70D can, for example, have approximately the same connector cross-section as the conductor channel 70A , since the cross section is transverse to the longitudinal axis LD of the sealing device 50D larger than the cross section of the sealing device 50A that is, there is adequate space and space for the conductor ducts 70D is available.

At this point it should be mentioned that the clamping devices 80 can also be dimensioned differently, so that, for example, the clamping devices 80 the sealing device 50D Can apply greater forces with respect to the clamping axis S than the clamping devices 80 the sealing device 50A . Accordingly have for example the tension anchor 81 the sealing device 50D larger cross-sections than the tension anchor 81 the sealing device 50A and / or are at the sealing device 50D feathers 91 with greater spring force than with the sealing device 50A intended.

The seal body 54A-54D are in one piece and consist of an elastic material, for example silicone elastomer, in particular a vinyl silicone rubber (VMQ) or methyl silicone rubber (MVQ). The elastic material of the sealing body 54A-54D has a hardness of at least 10 Shore A, preferably a hardness in a range from approx. 15 Shore A to 25 Shore A, in particular from approx. 20 Shore A.

A respective sealing device preferably has 50A-50D only have a single seal body at a time. However, it is also possible, for example, to have two or more sealing bodies, in particular in a row axis parallel to the longitudinal axis LD of the sealing device 50 , one behind the other or next to one another. For example, two sealing bodies 54B , 254B be provided, which are arranged one behind the other in the row direction. The seal body 54B , 254B can be made of one and the same elastic material, but also have different elastic materials. For example, the sealing body 54B consist of an elastic material with a hardness of 20 Shore A, while the sealing body 254B made of a somewhat harder material, for example with a hardness of 25 Shore A.

Conductor ducts 70B the seal body 54B , 254B be geometrically the same, so that, for example, the same or similar narrowing contours, which are explained below, are provided one after the other. But it is also possible that the softer sealing body 54B one the conductor channel 70B has constricting constriction contour to a greater extent than the harder sealing body 254B .

When the conductor ducts 70A-70D , which are generally referred to below as a conductor duct 70 are designated, are not used, that is, no conductor L is inserted, dummy bodies BK are preferably inserted, so that the sealing device clamped into the sealing seat 50 and / or the sealing body in the compression position 54 the respective conductor channel 70 tightly closed by the inner walls of the conductor duct 70 of the sealing body 54 lie tightly against the outer circumference of the dummy body BK.

Accordingly, conductors L, which are in the conductor channel 70 are inserted, in the clamping position of the sealing body 54 not seated and non-displaceable with respect to the through axis DA in the conductor duct 70 held. However, if the clamping devices 80 are not yet in the tensioned position, the L conductors are in the respective conductor duct 70 although displaceable with respect to the through axis DA, but so to speak sluggishly displaceable, so that it has a predetermined holding force in the respective conductor channel 70 are held in a non-displaceable manner with respect to the through axis DA.

This is on the respective conductor channel 70 a narrowing contour 71 intended. The narrowing contour 71 is, for example, like an hourglass in cross section. The narrowing contour 71 has sloping surfaces inclined to one another 72 on, between which a vertex section 73 is arranged. At the apex 73 limits the narrowing contour 71 the smallest connector cross-section of the conductor duct 70 .

At the longitudinal end areas of the conductor duct 70 on the opposite end faces of the sealing body 54 are provided, for example, cylindrical insertion sections 74 intended. A plug-in cross-section of the cylindrical insertion sections 74 and a plug-in cross-section of the passage openings 69 the clamping body 52 , 53 is equal. So therefore cover the clamping body 52 , 53 the connector cross-sections of the conductor ducts 70 do not and do not protrude into this in the sense of a support. The clamping body 52 , 53 act in areas next to the connector cross-sections of the conductor ducts 70 on the sealing body 54 on

On the outer peripheral surface 62 of the sealing body 54 are displacement cavities 75 intended. The displacement cavities 75 , for example trough-like depressions 76 , extend between cylindrical sections 77 at the longitudinal end areas or end areas of the sealing body 54 that the clamping bodies 52 , 53 opposite. The displacement cavities 75 can extend over the entire outer circumference of the sealing body 54 extend with respect to the longitudinal axis LD, as for example in the case of the sealing device 50B or 50C shown.

It is also possible that the displacement cavities 75 only over a partial circumference or an angular range of less than 360 ° around the outer circumference of the sealing body 54 extend. For example, the sealing body 54 the sealing device 50A in the embodiment of 7th and 8th exemplary displacement cavities 75A of this type exist. However, a trough-like constriction over the entire outer circumference of the respective sealing body is preferred 54 also with the sealing device 50A , such as in 13th shown.

The displacement cavities 75 are in the release position of the clamping device 80 and at free Conductor channel 70 , so without being in the conductor channel 70 a conductor L is plugged in, free. If now an operator or fitter puts a ladder L in the ladder channel 70 inserted, the conductor L is on the one hand at the narrowing contour 71 held, especially in the area of the apex 73 , on the other hand, however, at least part of the material of the sealing body 54 which is the narrowing contour 71 provides, drowned radially outward from the push-through axis DA, namely into the displacement cavity 75 into it. This becomes the outer peripheral surface 62 also between the cylindrical sections 77 likewise cylindrical or essentially cylindrical, ie the outer circumferential surface 62 is enclosed in the conductor channel 70 inserted conductor L or in the conductor duct 70 arranged dummy body BK already in the release position of the clamping device 80 essentially flat on the inner circumference of the respective cable duct 40 or the inner peripheral surface 49 at.

For example, the outer peripheral surface has 62 then starting from the in 11 contour shown when the conductor is not inserted the in 12th shown shape that the outer peripheral surface 62 in the area of the push-through openings 56 even if not in the conduit 70 located conductor L may have.

Of course, it is also possible that, for example, the cable duct 40 has a displacement cavity into which a respective sealing body is inserted 54 can deform. This is indicated in 4th based on a displacement cavity 75B on the cable duct 40 for the sealing device 50D . It is possible that only the line lead-through channel provides a displacement cavity and no displacement cavity is provided on the sealing body, but also that the sealing body and the conductor of the guide channel have corresponding displacement cavities, so that, for example, the displacement cavities 75 (or 75A) and 75B may be provided.

The displacement cavity 75B at the same time forms a form-fit contour 49B into which the sealing body 54 is deformable and is received there in a form-fitting manner, such that the sealing body 54 in the head of the guide channel 40 is received with respect to the insertion axis E shiftable. The form-fit contour 49B can also, for example, comprise or be formed by a rib arrangement (not shown).

The clamping body 52 , 53 and the sealing body 54 are preferably plate-like. The clamping body 52 , 53 and the sealing body 54 are preferably in one piece or from one piece.

However, a multi-part design is also possible. For example, in the case of the sealing device 50D Clamping body 52D and 53D provided, each of the two clamping body parts 52D1 , 53D1 have that by screws 53S are screwed together. The clamping body parts 52D1 , 53D1 are for example plate-like. Screw axes of the screws 53S run transversely to the longitudinal axis LD of the sealing device 50D .

• Das Schwenklager 104 ist ein Endbereichen 105 der Ringkörper 103 vorgesehen, sodass zu den Endbereichen 105 entgegengesetzte Endbereiche der Ringkörper 103 Verschluss-Endbereiche 106 bilden, die aufeinander zu und voneinander weg bewegbar sind. In der geschlossenen Stellung des Klemmrings 101 liegen Stirnseiten 107 der Verschluss-Endbereiche 106 aneinander an, vorzugsweise in einer Klemmstellung K, in der die Klemmaufnahme 102 ihren kleinsten Durchmesser oder kleinsten Innenumfang aufweist. In diesem Zustand sind die Flanschvorsprünge 14, 24, wenn sie in Eingriff mit dem Klemmring 101 sind, durch die Klemmvorrichtung 100 im Klemmsitz aneinander gehalten.

The clamping device 100 is designed as follows:

• The swivel bearing 104 is an end range 105 the ring body 103 provided so that to the end areas 105 opposite end portions of the ring bodies 103 Closure end areas 106 which are movable towards and away from one another. In the closed position of the clamping ring 101 lie front sides 107 the closure end areas 106 to each other, preferably in a clamping position K, in which the clamping receptacle 102 has its smallest diameter or smallest inner circumference. In this state, the flange projections are 14th , 24 when engaged with the clamping ring 101 are by the clamping device 100 held together in a press fit.

The two ring bodies 103 and thus at least the clamping ring 101 assign a recording 110 for the flange protrusions 14th , 24 on that by a floor wall 108 and side thighs 109 that from the bottom wall 108 protrude laterally, is limited. For example, form the bottom wall 108 and the side thighs 109 a cross-sectionally U-shaped configuration.

At the end areas 105 the ring body 103 are bearing projections 111 arranged, which can engage with each other, so that on the bearing projections 111 arranged bearing receptacles 119 align with each other. Then a bearing axis element can 112 , for example on the bolt body, through the bearing mounts 119 be pushed through to the pivot bearing 104 to build. The ring bodies 103 are at the end areas 105 designed identically, ie that for example on the side legs 109 one bearing projection each 111 is arranged, one of which on the inside of the holding receptacle 110 and the other on the free outside, outside of the holding receptacle 110 , on the respective side leg 109 is arranged. Thus are the ring bodies 103 identical in this regard.

Also the closure end areas 106 are designed identically, which is even clearer.

On the outer circumference 114 close to the end areas 105 , so close to the swivel bearing 104 , are swivel stops 113 arranged in the completely open state of the clamping ring 101 when the ring body 103 maximum around the swivel axis of the swivel bearing 104 are pivoted apart, butt against each other.

The locking device 120 is at the closure end areas 106 arranged. The locking device 120 has a closure member 126 on, which engages with a lock receptacle 127 can be brought to the clamping ring 101 to close and then to bring it into the clamping position K. The locking device 120 also forms a clamping means or a clamping device for the clamping device 100 .

The locking device 120 can optionally be attached to each of the ring bodies 103 be arranged because, as mentioned, the mechanical design of the ring body 103 at the closure end areas 106 is identical.

For example, the control lever 121 the locking device 120 optionally on each of the ring bodies 103 be attached by a bearing element in the form of a tie rod 130 pivotable on a ring body 103 or on the other ring body 103 is pivotally attached. There is a swivel bearing in each case 131 producible with which the tie rod 130 pivotable on this ring body 103 is stored. The swivel bearing 131 is for example based on a bearing axis element 133 , for example a bolt, can be produced, which is attached to a bearing mount 134 of the respective ring body 103 , for example, a corresponding bore or passage opening can be arranged. The bearing axis element 133 continues to enforce an inventory 135 of the tie rod 130 that with the inventory 134 flees. Thus is the tie rod 130 around a first pivot axis S1 pivotable with respect to the ring body 103 on which the swivel bearing 131 is provided, pivotally mounted.

Another pivot bearing is between the tie rod 130 and the control lever 121 provided, namely a pivot bearing 132 , which represents a second pivot bearing and the operating lever 121 regarding the tie rod 130 around a pivot axis S2 pivotable. For the manufacture of the swivel bearing 132 is another bearing axis element 133 , for example a bolt, through a bearing mount 136 of the tie rod 130 and another inventory 129 of the control lever 121 put through.

To secure the bearing axis elements 133 in the stock shots 129 , 136 and or 119 , 135 can fuse elements 137 , For example, retaining rings, clamping rings or the like may be provided that engage with the bearing axle elements 133 can be brought and these are shiftable with respect to their respective longitudinal axis, which in the mounted state of the pivot axis S1 or S2 corresponds to the stock recordings 129 , 136 or 119 , 135 holds

The swivel axes S1 and S2 are parallel to each other. The swivel axes S1 and S2 have a distance from one another, which is preferably approximately the length of the tie rod 130 corresponds to. Using the swivel axes S1 and S2 is the control lever 121 about two pivot axes with respect to the ring body 103 on which the swivel bearing 131 is arranged, pivotally mounted.

The control lever 121 has an arm portion 122 on that between a clamping portion 123 and a free end area 124 runs. At the free end area 124 is an operating handle 125 intended for gripping by an operator.

Between the clamping section 123 and the arm section 122 is the closing link 126 arranged. The closure member can therefore 126 by swiveling the control lever 121 engaged or disengaged from the lock receptacle 127 to be brought.

The lock mount 127 is present as a shift recording 152 configured that has an insertion opening 156 for inserting the closure member 126 provides. Then the closure member can 126 in the shift recording 152 between the end stops 153 , 154 be moved, between which there is a guide contour 155 extends.

The end stop 153 forms a clamping end stop 153 and also a clamping contour 151 , with which a clamping actuator 150 can be brought into engagement to produce the clamping position K. The clamping actuator 150 at the same time forms the closure member 126 or the closure member 126 represents the clamping actuator 150 ready.

For example, the closure member comprises 126 / the clamping actuator 150 across the outside in front of the arm section 122 of the control lever 121 protruding actuating cams or actuating projections.

At the closure end areas 107 are two shift recordings each 152 arranged opposite one another, in the closure member 126 or clamping actuator 150 , so for example the actuating projections that are laterally in front of the operating lever 121 protrude, can intervene. The shift recordings 152 are on mounting legs 138 provided that radially outward in front of the outer circumference 114 of the ring body 103 at the Closure end area 106 protrude. Between each pair of receiving legs 138 is a recording 128 provided in which, for example, the tie rod 130 and / or the control lever 121 can intervene.

To close the clamping device 100 so is first the closure member 126 through the insertion opening 156 through into the shift mount 152 , so the lock mount 127 introduced. The shift shot 152 has a T-shape with the longitudinal leg between the end stops 153 , 154 runs and the middle leg the insertion opening 156 provides. So if the closing link 126 and thus the clamping actuator 150 in the shift recording 152 is recorded, it is between the end stops 153 , 154 along the guide contour 155 or the longitudinal leg of the T-shaped receptacle.

The control lever 121 decreases when inserting the closure member 126 into the lock receptacle 127 first a release pivot position LS. The arm section is in the release pivot position LS 122 at a large angle, for example of 90 ° and more, from the outer circumference 114 of the clamping ring 101 from. The clamping actuator can 150 at the release end stop 154 the shift recording 152 issue.

Then the control lever 121 from the rear gripping pivot position HS in the direction of a clamping pivot position KS further to the clamping ring 101 pivoted towards so that the arm section 122 finally in the clamping pivot position KS essentially tangential to the outer circumference 114 of the clamping ring 101 runs. The clamping actuator slides 150 from the release end stop 154 in the direction of the clamping end stop 153 and finally lies against it, which then functions as a clamping contour 151 can meet. The clamping actuator 150 is namely in engagement with the release end stop in the last pivot section in the direction of the clamping pivot position KS 154 or the clamping contour 151 so that the control lever 121 in this last pivot section essentially about a pivot axis S3 pivots that are parallel to the pivot axes S1 and S2 through the clamping actuator 150 runs through it. The operating lever is 121 adjusted to an over-center position in which he presses the clamping actuator with maximum force 150 in engagement with the clamping end stop 153 presses, thereby also the front sides 107 of the closure end area 106 the ring body 103 be pressed or clamped together.

• Der Bedienhebel 121 kann nämlich aus der Klemm-Schwenkposition KS zunächst um einen vorbestimmten Winkel in die Hintergreif-Schwenkposition KS verschwenkt werden, ohne dass dadurch die Verschluss-Endbereiche 106 voneinander weg bewegt werden. Dabei gleitet der Klemmbetätigungskörper 150 vom Klemm-Endanschlag 153 an der Führungskontur 155 entlang in Richtung des Löse-Anschlags 154. Der Abstand zwischen den Endanschlägen 153, 154 stellt einen Freigang F für den Bedienhebel 121 bereit. In der Hintergreif-Schwenkposition KS ist der freie Endbereich 124 jedenfalls so weit vom Außenumfang 114 des Klemmrings 101 entfernt, dass er bequem mit einem Finger, vorliegend sogar mit mehreren Fingern, von einem Bediener hintergriffen werden kann, um den Bedienhebel 121 weiter in Richtung der Löse-Schwenkposition LS zu verstellen. Dabei wirkt der Klemmbetätigungskörper 150 eigentlich als Löse-Betätigungskörper, indem er nämlich auf den löse-Endanschlag 154 im Sinne eines Öffnens des Klemmrings 101 einwirkt.

When can you imagine that swiveling an operating lever from an over-center position in the direction of a release position of the clamp is cumbersome and involves considerable effort. The control lever is used in particular 121 also the two closure end areas 106 from the clamping position K in the direction of the open position O away from each other. If in this case, for example, the flange projections 14th , 24 in the holding fixture 110 a considerable amount of operating force is also required. The measure explained below provides a remedy here:

• The control lever 121 can namely be pivoted from the clamping pivot position KS first by a predetermined angle into the engagement pivot position KS without thereby affecting the closure end regions 106 be moved away from each other. The clamping actuator slides 150 from the clamping end stop 153 on the guide contour 155 along in the direction of the release stop 154 . The distance between the end stops 153 , 154 provides a clearance F for the control lever 121 ready. The free end area is in the rear gripping pivot position KS 124 at least so far from the outer circumference 114 of the clamping ring 101 removes the fact that an operator can comfortably grip the operating lever from behind with one finger, in the present case even with several fingers 121 to be further adjusted in the direction of the release pivot position LS.
