Description

Sealing device with a hard sealing body

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 through a Clamping device for compressing the sealing body from a release position into a clamping position can be adjusted relative to one another along a span axis, the sealing body with respect to one another I the insertion axis in the release position has a smaller outer circumference than in the clamping 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 clamping 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 sealing device having a spring arrangement with at least one spring, the spring force of which acts with a force component parallel to the clamping axis on the sealing body. The invention also relates to a distributor device with a Dichtungsvorrich 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.

So-called gel seals are typical for this area of application, i. H. Seals, the sealing body of which are made of soft, so to speak, almost flowing elastic material. The advantage of such gel seals is that they adapt themselves optimally to the surroundings to be sealed, namely the conductor and the cable duct, and are, so to speak, conformable. The spring arrangement ensures that pressure is exerted on the gel or the soft, elastic mass of the sealing body, so that it does not lose its sealing effect as much as possible even after a long period of time. However, it has been shown that a certain shrinkage or a certain resilience leads to the fact that the tightness decreases over time.

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

To achieve the object, it is provided in a sealing device of the type mentioned above that the elastic material of the sealing body has a hardness of at least 10 Shore A.

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 one cable feed-through channel for passing cables from the vicinity of the distributor device into the interior of the distributor housing, the distributor device having a sealing device according to the invention. Before geous, the housing base has a bottom wall and at least one on the Channel body arranged on the bottom wall, in which the at least one through the sealing device to be closed or closed line leadthrough approximately channel is provided. The housing base and the housing cover are preferably held together by a clamping device with a clamping ring that surrounds the housing, with the end faces abutting against one another.

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 to harder bodies, but also to 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 give in 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 line lead-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 Dichtkör by, that is, a sealing body that has a hardness of at least 10 Shore A, thus 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, as a seal for a cable duct or a cable duct of a system. to use the 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 passed. The sealing device can have conductor channels adapted to the lines to be passed through and to be sealed, ie conductor channels with matching inner circumferential geometry in and through cross-sections. It is also possible for the Dichtungsvor direction 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) can also be used ), 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.

Flybrid materials, i. H. For example, sealing bodies, which consist of two different elastic materials under, are easily possible. However, it is preferred if the sealing body consists of a single elastic rule material.

In any case, it is possible for the sealing body to have two or more different elastic materials. The different materials can be arranged in layers one above the other or next to one another, for example. For example, it is conceivable that the materials are arranged one behind the other in relation 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 an elastic material and recordings on the other elastic material, as mixtures or the like in the sealing body.

It is advantageously provided that the at least one conductor channel of the sealing body has at least one in the sense of narrowing the conductor channel in this transversely through the plug-in axis protruding constriction contour for holding a conductor inserted into the conductor channel in the release position of the clamping device. A basic idea here is that the conductor channel itself has a plug-in cross-section which 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 the conductor already has in the release position of the clamping device pre-fix, so to speak, this fixation then being further improved by the tensioning 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 finally establishes a tight fit 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 through 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 a sand clock-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. From opposite end areas or insertion openings of the conductor channel so each rising, inclined inclined surfaces can be provided. 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 area 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 channel at a longitudinal distance with respect to the through axis to the at least one Is narrowing contour. Constrictions of the conductor duct 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, in particular between the outer circumferential surface of the sealing body and the line duct, is provided, 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 in the state that 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 can namely NEN for example with respect to the insertion axis in a longitudinal position where the narrowing contour of the sealing device comes to rest, Aussparun conditions or the like, other recesses, depressions, etc. be provided as a displacement cavity. It is easily possible that a displacement cavity is seen on both the Lei processing duct and the sealing body, in particular at the same longitudinal position with respect to the insertion axis or the insertion 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. Thus, 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.

But it is also possible that the constriction contour is supported on the conductor arranged in the conductor channel and the at least one displacement cavity is provided and designed so that the elastic material of the sealing body essentially or only in the tensioned position in the at least one displacement cavity is displaceable into it. It is a basic idea that the displacement cavity provides a displacement reserve, so to speak is 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 the at least one displacement cavity already in the release position provides a receiving space for the elastic material in the area of the constriction contour, which is then not yet completely filled with the elastic material, but then when the clamping device produces the clamping position, 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 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 depression extends over the entire outer circumference of the sealing body, in particular in the area of the at least one narrowing contour.

It is also advantageously possible that the displacement cavity, in particular the at least one recess, extends over the entire outer circumference of the sealing body of the sealing body, which extends around the longitudinal axis of the sealing device.

However, it is also possible that the at least one displacement cavity extends over a partial circumference of the sealing body that extends around the longitudinal axis of the sealing device. It is possible that several displacement cavities that each extend only over a partial circumference of the sealing body, are 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 indentations 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 only on 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 having. Other cylindrical shapes, for example elliptical cylinders or oval cylinders, are also easily possible. It is possible, for example, to provide cylindrical outer circumferential surfaces between which a constriction is provided on the longitudinal end regions of the sealing body with respect to the longitudinal axis of the sealing device or the insertion axis of the at least one conductor channel is arranged in the form of 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, that is to say that a bottom wall of the trough extends in the direction of a cylinder diameter the aforementioned cylindrical outer circumferential surfaces provided on the longitudinal end regions of the sealing body are displaced, so that the sealing body already has a substantially cylindrical shape in the release position stalt or has a completely cylindrical shape on its outer circumference with respect to the longitudinal axis of the sealing device.

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 narrowing 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.

In order to provide constriction contours lying one behind the other with respect to the insertion axis, it is possible for the sealing body to be in several parts, or to be formed from a first and a second sealing body parts arranged next to one another with respect to the longitudinal axis of the sealing device, in particular directly and in contact with one another that several, for example two, sealing bodies are provided, each of which provides a narrowing 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. The sealing device advantageously has at least one closure body for closing the conductor channel. The at least one closure body can be inserted into the conductor duct, for example along the feed-through axis or path, along which the conductor can otherwise be inserted into the conductor duct, and can be removed from the conductor duct so that the conductor duct is free for the conductor to be inserted through. In other words, the conductor can be inserted into the conductor duct or pushed through the conductor duct when the closure body is removed from the conductor duct. The closure body is advantageously frictionally and / or positively held in the conductor channel when the tensioning bodies are in the release position and / or are moved out of the release position, for example not yet fully or only partially tensioned by the tensioning device. If several conductor channels are provided, several closure bodies are provided accordingly.

The closure body can, for example, be pushed through and / or inserted through one or both clamping bodies in order to get into the conductor channel. It is advantageous if the closure body penetrates only one clamping body and does not protrude in front of the other clamping body or does not penetrate into it. In any case, it is essential that the closure body closes the conductor channel.

The closure body has, for example, a rod-like or pin-like shape. The locking body is designed, for example, as a locking pin or rod.

The closure body advantageously has a grip section for gripping by an operator and a plug section which is provided for plugging into the conductor duct. A closure section is advantageously provided on the plug-in section, that is to say, for example, a section with a larger cross section, in order to close the conductor duct.

It is advantageous if a form-locking receptacle for the form-locking engagement of one or the at least one constriction contour is provided on the closure body, for example on the closure section. The narrowing Contour narrows the conductor channel transversely to the push-through axis and / or projects into the conductor channel transversely to the push-through axis. The narrowing contour advantageously serves to hold the closure body in the conductor duct, in particular also when the clamping device is not in the clamping position and / or in its release position.

A grip section is provided, for example, on that part or longitudinal section of the closure body which protrudes in front of one of the clamping bodies. A support body or flange body can be provided between the closure section and the grip section, which is provided for support, in particular at the edge, on a push-through opening of the clamping body through which the closure body is pushed. The support body or flange body can also be designed and / or provided to cover or close the push-through opening. Thus, the closure body also closes the through-opening of the clamping body or is supported on the clamping body in addition to the through-opening.

The hardness and / or resilience and / or elasticity of the sealing body is dimensioned such that the closure body is held in the conductor channel even when the clamping device has not or not completely adjusted the clamping body into the clamping position. Thus, for example, a fitter can remove one or more of the closure bodies from a respective sealing device in order to push through the conductor duct that has become free without the other closure bodies being able to get out of the respective conductor ducts into which they are inserted. The closure body can only be removed from the conductor duct in which it is received by actively actuating a respective closure body, for example by pulling control action on the handle section.

The form-fit receptacle of the closure body advantageously has a contour that represents a counter-contour for the narrowing contour of the conductor channel. The contour of the closure receptacle can run identically to the narrowing contour and / or be a negative of the narrowing contour. But it is also possible that the form-fit receptacle, for example, has a different shape than the constriction contour. It is advantageous if the narrowing contour is supported in a form-fitting manner in the form-fitting receptacle of the closure body when the clamping body or the clamping device assume the clamping position. With regard to the design of the clamping body, different possibilities are given.

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 abutment and support bearing to be described of a tensioning anchor of the clamping device, a reinforcement, in particular made of Me tall, is advantageous. In general, it should be noted that the clamping body 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 flat plastic and / or fiber-reinforced plastic. Combinations of these mate rials, for example mixed construction, d. H. a clamping body, for example made of plastic with a metal reinforcement, are possible with a clamping body without further res.

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 a 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 a respective conductor channel.

It is advantageous if the clamping body 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 Processing device does not engage or protrude into the conductor channel and / or does not protrude into the plug-in cross section of the conductor channel and / or the inner circumferential contours of the passage opening and the conductor channel next to the passage opening are aligned 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 area 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, regardless 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, e.g. funnel-shaped, step-shaped or the like, which is arranged immediately next to the clamping body with respect to the longitudinal axis of the sealing device is designed so that the elastic material is exposed at the plug-in area and / or is unstiffened. In particular, the clamping body arranged next to the conductor channel does not act there in the sense of supporting the sealing body. 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 tension body does not affect 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. by, 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 plug-in 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 positive hold of the sealing device on the cable duct, in particular on a duct body having the cable duct, 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 designed as an annular groove, for the 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-fitting receptacle is seen, 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 conduit bushing, possibly at right angles thereto. 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 pushed out of the conduit guide channel because the air volume enclosed in the interior is heated and expands accordingly. The following measure provides a remedy, for example: it is advantageously provided that a tensioning body has a screw receptacle for a retaining screw for screwing the sealing device to a channel body providing the line feed-through channel. Using 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 line lead-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 advantageous 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 that 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 is provided to be closed or closed by the sealing device.

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

It is preferably provided that the housing base and / or the housing cover preferably consist of plastic. Fiber-reinforced plastic is particularly advantageous. Without further ado, however, other materials, for example metal or the like, are also possible for the housing base or the housing cover. For example, it is also possible that a housing cover made of plastic or a housing base made of plastic is reinforced by metal, for example a metal plate, metallic struts or the like.

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

A carrier with holding receptacles for distribution modules is preferably arranged on the housing base. The carrier is, for example, tower-like and / or perpendicular right 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 distribution modules are or include, for example, splice trays 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, retaining 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 series arrangements run preferably 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 are arranged with respect to the longitudinal axis of the sealing device on opposite sides of the sealing device or on the same side 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 member 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 the interior of a distributor housing or a splice sleeve so that it is protected from contamination. For example, icing in winter can 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 receiving 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 is dimensioned with respect to its longitudinal axis so 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 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 supporting part of the sealing body, it being advantageous that the sealing body is made of a harder material on the supporting part than the elastic material or the elastic material is reinforced on the supporting part , for example by a reinforcing 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 clamping 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 Spannkör pers.

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, i.e. when its screw turns are in contact with one another, and a hardness or a modulus of elasticity of the sealing body are optimally coordinated so that the spring can be adjusted to the maximum pre-tension 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, preloading it to a block, so to speak. 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 to adjust the clamping device between the release position and the clamping position and the support bearing is adjustable with respect to the clamping axis by means of an adjusting means which can be actuated by one or the actuating member. The support bearing and / or the abutment can be formed, for example, by Stützvor jumps on a bolt section of the tensioning anchor. The support bearing and / or the abutment can support the clamping body directly, for example, directly against the respective clamping body, or indirectly by, for example, an underlay body and / or a spring between the clamping body and the Stützla ger or abutment is arranged.

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 that an abutment or support bearing form a solid, integral part of the Bolzenab section, for example in the manner of a head of a nail or the like. But it is also possible that both, namely abutment and support support, 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 ger. 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 which 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 for twist-proof folding on the first clamping body and / or on the second clamping body and / or on the sealing body, with an anti-rotation counter-contour for the respective first clamping body or second clamping body or the sealing body the anti-rotation contour of the tensioning anchor is arranged. The anti-rotation contour can, for example, be realized by a polygonal outer circumferential contour 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 if the anti-rotation counter-contour has an anti-rotation mount extending parallel to the clamping axis, in which the anti-rotation contour is received displaceably and twist-safe when adjusting the clamping device between the clamping position and the release position along the clamping axis. 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 Verdrehsi cherungsaufnahme extends advantageously parallel to the clamping axis of the clamping anchor. Without further ado, however, a screw-shaped anti-rotation lock mount would also be conceivable, for example, which, however, 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 is preferred over the entire surface of the sealing body to be compressed. 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. It is also possible, however, 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 cut by the insertion axis or a central longitudinal axis of the sealing device. The insertion axis is for example provided centrally in the middle with respect to the cable bushing. 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 into the bolt portion is supported.

It is preferred if the sealing device has a conductor support device with at least one conductor support body, which on a side opposite to the sealing body and / or facing away from the sealing body of a the clamping body protrudes and / or protrudes in front of the clamping body. The conductor support body has at least one support contour for supporting a conductor inserted through the conductor channel. Thus, the conductor can be supported on the support contour when it is pushed through the sealing device, that is, penetrates the conductor channel. It is preferred if the conductor support body is provided to support the conductor in an interior space of the distributor device, in particular the splice sleeve.

The conductor support body advantageously has at least one fastening contour, for example a hook, a passage opening or both, for fastening a flexible holding element, the holding element being loopable around the conductor supported on the support contour. The flexible retaining element is, for example, a retaining strap, in particular a cable tie. The fastening contour is seen, for example, on a floor area or base area of the support contour. The holding element can advantageously be connected to the conductor support body through the passage opening. The passage opening extends, for example, between the support contour provided for supporting the conductor and an opposite rear side of the conductor support body. For example, passage openings can be provided for the flexible holding element, on which also hooks are provided. A hook protrudes into the passage opening, for example. But it would also be possible that only one hook is provided and no through openings. The hook projects, for example, in front of the support contour for the conductor or is arranged next to the support contour.

The support contour has, in particular, a receiving trough or receiving trough having a longitudinal shape for the conductor. For example, the receiving trough extends in the longitudinal direction parallel or essentially parallel to the insertion axis along which the conductor can be inserted through the conductor channel.

In particular, it is advantageous if, in a sealing device according to the invention, the support contour is provided with a respective conductor channel and / or a through- Insertion opening of the clamping body is aligned on which the ladder support device is seen before.

It is also advantageous if the support contour is designed such that a conductor supported on the support contour does not come into contact with a component of the tensioning device, in particular a spring of the tensioning device. For example, the support contour and / or the conductor support body forms a kind of protective shield or protective plate for the conductor.

It is particularly preferred if the components of the tensioning device, for example one or more springs, are arranged between, for example, two conductor support bodies, so that they are covered and / or, so to speak, on opposite or mutually angled sides by the conductor support device are sheathed. For example, the conductor support bodies can delimit an intermediate space in which one or more components of the tensioning device, for example a spring or the like, are arranged.

It is preferred if the conductor support device has a base from which the at least one conductor support body protrudes or from which several conductor support bodies protrude, for example in the form of a fork.

It is advantageous if the base is held on the clamping body by the clamping device. It is also advantageous if at least one passage opening of the base is provided for an element of the clamping device, so that the element of the clamping device, for example a clamping anchor, can penetrate the passage opening.

The base also advantageously has an abutment surface for a spring of the tensioning device. Thus, the base of the ladder support device can, for example, represent a hard component supporting the spring, so that a force acting on the tensioning body on which the base is supported is distributed over a larger area. At this point it should also be mentioned that the at least one conductor support body can also be in one piece with the clamping body from which the conductor support device protrudes.

An embodiment is particularly preferred in which two or more conductor support bodies, in particular fork-shaped, protrude from the base.

It is also advantageous if the conductor support body and / or the support contour protrude further than the tensioning device in front of the tensioning body on which the conductor support device is provided.

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 Fe countries can protrude. Thus, the sealing device in the manner of a cartridge or a sealing module can be inserted into the cable duct.

For example, a screw to be screwed into the sealing device and a channel body accommodating it or the like other form-fitting retaining measures, it is possible to fix the sealing device in the Lei processing duct, 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 duct with respect to the insertion axis. The anti-rotation contour as such ensures that the sealing device in the line duct cannot be rotated about the insertion axis.

It is advantageously provided that the anti-rotation contour at least has an angular or non-circular or elliptical or oval cross-section and / or an angular or non-circular or elliptical or oval outer circumferential contour a component of the sealing device, in particular the sealing body and / or at least one clamping body or both clamping bodies, preferably all components of the sealing device that engage in the cable ducting channel when the sealing device is installed. Thus, the sealing device only fits in predetermined angular positions relative to the insertion axis in the line lead-through channel and cannot be rotated there.

The component accommodating the sealing device, for example a distributor housing, in particular a channel body of a distributor housing, advantageously has an anti-rotation counter-contour to hold and / or support the sealing device in a non-rotatable manner. The anti-rotation contour and the anti-rotation counter-contour lie against one another when the sealing device is arranged in the cable duct 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 plurality of conductor ducts being arranged next to one another or in a ring, in particular circular, in a row axis. The sealing body advantageously has an insertion opening for inserting the conductor into the conductor channel of the sealing body, through which the conductor can be inserted from an outer circumference of the sealing body into the conductor channel transversely to the insertion axis along which the conductor can be pushed through the conductor channel.

Insertion openings of the conductor channel are provided on the end faces of the sealing body, through which the conductor along the through axis through the

Sealing body can be pushed through. The conductor channel and / or the insertion opening extend between the end faces of the sealing body.

The insertion opening extends between the conductor channel and the Außenum catch of the sealing body. The outer circumference of the sealing body is provided between the end faces.

The insertion opening is preferably designed as a slot which extends between the conductor channel and the outer circumference of the sealing body.

The sealing body is advantageously elastically bendable or deformable for opening and closing the insertion opening, in particular about the push-through axis or an axis parallel to it. In a closed position of the insertion opening, side surfaces delimiting the insertion opening advantageously lie flat against one another. The insertion opening preferably penetrates the constriction contour or at least one constriction contour. The narrowing contour narrows the conductor channel transversely to the push-through axis and / or protrudes into the conductor channel transversely to the push-through axis. The narrowing contour is advantageously used to hold the conductor or a conductor or a closure body arranged in the conductor duct instead of the conductor and is designed to hold the conductor or closure body in the conductor duct in a frictional and / or form-fitting manner.

An optical waveguide distribution housing 10 of a distribution device 5 has a housing base 11 which is closed by a housing cover 15. The housing base 11 has a bottom wall 12 which forms a bottom of the distributor housing 11. The distribution device 5 forms, for example, a splice sleeve 6 which can be used in harsh environmental conditions, for example cable ducts, etc.

The housing cover 15 is designed in the manner of a cover 16. The housing cover 15 has an elongated shape and extends along it a longitudinal axis LG of the distributor housing 10. Reinforcing ribs 18 are provided on a peripheral wall 17 of the housing cover 15, which run transversely to the longitudinal axis LG, as well as mutually opposite sides of longitudinal ribs which run parallel to the longitudinal axis and extend up to a top wall 19 of the housing cover 15 extend. The top wall 19 is the bottom 12 of the distributor housing 11 opposite.

The housing cover 15 and the housing base 11 delimit an interior space 13 which is sealed against environmental influences. The interior 13 extends along the longitudinal axis LG between the housing cover 15 and the base 12 and is delimited on the circumferential side by the circumferential wall 17.

A sealing arrangement 20 is provided on opposite and abutting end faces of the housing base 11 and the housing cover 15. For example, the sealing arrangement 20 comprises at least one sealing projection 21 and / or 22 protruding from the housing base 11 in the direction of the housing cover 15. The sealing projections 21, 22 are ring-shaped. At least one sealing projection 21 and / or 22 engages in a seal receptacle of the housing cover 15, which is not visible in the drawing, or rests against an end face of the housing cover 15. A particularly elastic sealing ring 23, for example an O-ring, is advantageously arranged between the sealing projections 21, 22, for example in a sealing receptacle formed by a space between the sealing projections 21, 22.

Sealing contours of the sealing arrangement 20 can be brought into engagement with one another by an insertion movement of the housing cover 15 and the housing base 11 parallel to the longitudinal axis LG in order to seal the interior 13 tightly against environmental influences.

Radially outwardly in front of the housing base 11 and the housing cover 15, annular flange projections 14, 24 protrude which, when the housing base 11 is covered by the housing cover 15, that is, it is in contact with the housing base 11, lie opposite one another and, in particular, lie flat against one another. The sealing arrangement 20 is provided on opposite end faces of the flange projections 14, 24. For example, the sealing ring 23 rests on the flange projection 24.

The flange projections 14, 24 are held together by a clamping device 100. The clamping device 100 has a clamping ring 101 which is suitable for enclosing the distributor housing 10. The clamping ring 101 closes a clamping receptacle 102, half of which is bounded by an annular body 103. The ring bodies 103 are pivotably mounted on one another with a pivot bearing 104, so that the ring bodies 103 can be pivoted away from one another and towards one another in order to open or close the clamping receptacle 102. To open or close the clamping device 100, a locking device 120 is provided, which can be operated by means of an operating lever 121.

A carrier 25 projects from the bottom wall 12 into the interior 13, on which holding receptacles 26 for distributor modules or distributor cassettes 27, for example so-called splice cassettes, are arranged. The distributor modules or distributor cassettes 27 are preferably pivotably mounted on the holding receptacles 26, so that they are easily accessible for the assembly of conductors. In FIG. 3, for example, two distributor modules or distributor cassettes 27 are shown which are pivoted away from one another. The distribution cassettes 27 can be held in a pivoted position towards the carrier 25 by means of a belt 25A, for example.

In addition to or on the holding receptacles 26, Leiterführungsele elements 28 are preferably arranged through which a conductor L shown in dashed lines in the drawing can be passed. The distributor modules 27 have, for example, connector plugs 29 which can be connected to individual light guides, not shown in the drawing, which are contained in the conductor L. Plugs (not shown in the drawing) can be plugged into the connection plug 29, which are also connected to conductors L2 running in the interior of the distributor device 15. The ladder L2 forms the components of so-called patch cables, for example. However, it is also possible that conductors L introduced into the interior 13 are or are directly connected to one another, for example by splicing, in particular on a distributor module 27B configured as a splice cassette.

The conductor L and other conductors are passed through the housing base 11 into the interior space 13, which is sealed against environmental influences by the housing base 11 and the housing cover 15. Furthermore, other sealing measures have been taken, which will become clearer below.

On its side facing the interior 13, the bottom wall 12 has a rib structure 12A with one or more ribs 12B, 12C. The rib structure 12A forms, for example, a type of rib grid that stiffens the bottom wall 12. Furthermore, the rib structure 12A carries a base 25B of the carrier 25. On the base 25B, in particular on the side of the carrier 25 facing the bottom wall 13, hooks or similar other holding elements 25C for guiding and holding the conductors L are advantageously provided.

On the side facing away from the interior 13 channel bodies 30, 31, 32, 33, 34, 35, 36, 37, 38, 39 are arranged on the bottom wall 12, which together form a channel body arrangement. The channel bodies 30-39 are tubular and each have a line lead-through channel 40. The lines lead through channels 40 have inner circumferential geometries that depend on the cross section or the inner circumferential geometry of the respective channel body 30-39. Nevertheless, for the sake of simplicity, they are each designated as line lead-through channel 40.

A respective channel body 30-39 has a tubular, essentially cylindrically extending circumferential wall 41, on whose free side facing away from the bottom wall 12, that is to say a free end region 43, a respective end wall 42 is arranged.

FIG. 5 shows the housing base 11, so to speak, in the basic state, ie when the distribution device 5 has not yet been equipped with conductors. In this case are namely, the free end faces or end regions 43 on which the end walls 42 are provided are still closed by the end walls 42.

To equip, so to speak, cabling, the distributor device 10 with, among other things, the conductors L, the end walls 42 are separated from the peripheral walls 41, for example using a schematically illustrated separating tool T.

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

The so-called edge-side channel bodies 30, 33, 34, 37, 38 and 39 are easily accessible from the outer circumference area or outer edge area 45 of the housing base 11 with the cutting tool T, so that the end walls 42 of these aforementioned channel bodies are easily removed from the tubular body, i.e. the circumferential wall 41, of the channel body 30, 33, 34, 37, 38 and 39 can be separated.

But the channel bodies 31, 32, 35, 36, so to speak, in the middle or in a central area 46 of the housing base 11 are also readily accessible to the cutting tool T by having their free end areas or end faces 43 in front of the edge channel bodies 30, 33, 34 , 37, 38 and 39 protrude freely.

The end faces or free end regions 43 of the edge-side channel bodies 30, 33,

34, 37, 38 and 39 project in front of the bottom wall 12, for example, at a longitudinal distance A1. In contrast, the end faces of the so-called central channel bodies 31, 32, 35, 36 project in front of the bottom wall 12 at a longitudinal distance A2 which is greater than the longitudinal distance A1 by a difference DA. The central channel bodies 31, 32, 35, 36 form a group of a total of 4 channel bodies, each channel body 31, 32, 35, 36 being arranged, so to speak, in a corner region of an imaginary rectangle. Thus, each channel body 31, 32, 35, 36 is, so to speak, easily accessible for the cutting tool T from the corner area of this imaginary rectangle via an edge channel body 30, 33, 34, 37, 38 and 39 arranged next to it.

When the end walls 42 are removed from the channel bodies 30-39, a plug-in cross-section of their respective cable feed-through channel 40 is freely available for the insertion of sealing devices 50A, 50B, 50C, 50D. The sealing devices 50A, 50B, 50C, 50D are functionally similar, which is why they are also generally referred to as Dichtungsvor direction 50 in the following description.

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

Sealing devices 50 can along insertion axes E1, E2, E3, E4,

E5, E6, E7, E8, E9 are inserted into the cable ducts 40 of the channel body 30-39 and then lie tightly against a respective inner peripheral wall surface 49 of a channel body 30-39. Furthermore, the sealing devices 50 can be supported on the end faces 48 of the peripheral walls 41 of the channel bodies 30-39, so that these end faces 48 have longitudinal stops with respect to the respective insertion axis E1, E2, E3, E4, E5, E6, E7, E8, E9 for the sealing devices 50 deploy.

The insertion axes E1, E2, E3, E4, E5, E6, E7, E8, E9 are also referred to collectively as the insertion axis E below.

The insertion axes E run parallel to one another, preferably also parallel to the longitudinal axis LG of the distributor housing 10. All of the end regions are thus or end faces 43 and accordingly all cable ducts

40 accessible from the same side to conductors, such as the conductor L and other conductors not shown, to introduce through the cable ducts 40 through into the interior 13 to implement the distribution measures there, for example using the distributor modules 27, such as light conductors to splice open and to connect with other light guides.

The end faces 48 of the cable ducts 40 or the peripheral walls

41 support the sealing device 50 with a force direction K1 parallel to the plug-in axis E against a movement in the direction of the interior 13 on the respective line bushing 40.

Furthermore, screw receptacles 47 are provided on the end faces 48 of the peripheral walls 41, the screw axes or longitudinal axes of which run parallel to the respective insertion axis E. For example, one or a pair of screw receptacles 47 are provided on opposite sides of a respective channel body 30-39. The screw receptacles 47 are provided on screw domes 47A, which radially outward, i. H. on the outside of a respective line duct 40, in front of the peripheral wall 41 are in front of.

The screw domes 47A preferably provide anti-rotation counter contours for the sealing devices 50, which hold the sealing device 50 in the line feed-through channel 40 against rotation VD with respect to the insertion axis E so that they cannot rotate.

The main function of the screw receptacles 47, however, is that retaining screws 51 screwed into the screw receptacles 47 hold the sealing device 50 in a non-slip manner with respect to the insertion axis E and / or with respect to a direction of force K2 away from the interior space 13 in the respective cable duct 40 Sealing device 50 also with regard to the direction of force K1 in its line lead-through channel 40. The inner circumferential wall surfaces 49 are designed as anti-rotation counter contours 49A for the rotation-proof holding and / or support of the sealing devices 50 with respect to the insertion axis E. The inner circumferential wall surfaces 49 namely have a non-circular, for example elliptical or oval, cross-sectional contour, so that the sealing devices cannot rotate about the insertion axes E relative to the inner circumferential wall surfaces 49.

The sealing devices 50A, 50B, 50C, 50D each have pairs of clamping bodies 52A, 53A, 52B, 53B, 52C, 53C, 52D, 53D, between which a sealing body 54A, 54B, 54C, 54D is arranged. To simplify the following description, the pairings of the clamping bodies 52A, 53A, 52B, 53B, 52C, 53C, 52D, 53D are also referred to as clamping bodies 52, 53 and the sealing bodies 54A, 54B, 54C, 54D are also referred to as sealing bodies 54, and if so the clamping body and sealing body differ from one another geometrically, but functionally have a similar structure. The clamping bodies 52, 53 have through openings 55, 56 for inserting clamping devices 80, namely clamping anchors 81. The through-holes 55, 56 are aligned with through-openings 57 of the sealing body 54, so that the tensioning anchors 81 can be pushed through the aligned through-openings 55-57 in order to move the tensioning bodies 52, 53 relative to one another along a tensioning axis S, which is parallel to a longitudinal axis LD of a respective one Sealing device 50 runs to tension. As a result, the sealing body 54, which is sandwiched between the clamping bodies 52, 53, is compressed.

At their longitudinal end regions, the tensioning anchors 81 have a support bearing 82 and an abutment 83, between which a bolt section 84 extends. The bolt section 84 comprises screw sleeves 85, 86 which are inserted into one another at their one longitudinal end area and are connected to one another by a transverse bolt 87 and each have a screw receptacle at their opposite, free longitudinal end areas. A longitudinal axis of the transverse bolt 87 runs transversely, in particular at right angles transversely, to the clamping axis S. The transverse bolt zen 87 is pushed through, for example, holes 87A in the screw sleeves 85, 86 that are aligned with one another and fixed in these, for example, pressed or glued.

An abutment screw 88 is screwed into the screw sleeve 85, the screw head of which provides the abutment 83. A clamping screw 89 is screwed into the screw sleeve 86, the head of which provides an actuating element 90 and the support bearings 82. At the head of the clamping screw 89, for example, a Phillips-head contour or the like other entrainment contour for a tool, in particular a screwing tool, is angeord net with which the clamping screw 89 can be screwed or unscrewed into the screw sleeve 86 in order to move the clamping device 80 from a release position to adjust a clamping position and vice versa.

In principle, it would of course be possible for the abutment screw 88 to be actuated for clamping purposes. In the present exemplary embodiment, however, it is provided that the abutment screw 88 is basically screwed only once, namely around a spring 91 of a spring diameter 92 between the head of the abutment screw 88 on the one hand and the cross bolts protruding in front of the screw sleeves 85, 86 on the other 87 to cock. The spring 91 is penetrated by the bolt section 84. The spring 91 is a coil spring for example. The spring 91 is, so to speak, preassembled and / or prepositioned by assembly with the abutment screw 88 on the tensioning devices 80 or the tensioning anchor 81.

It is therefore possible that the spring 91 is supported only or exclusively on the abutment 83 / the head of the abutment screw 88 and the cross bolt 87 in the release position of the clamping device 80. However, if the clamping device 80 is adjusted from its release position into the clamping position, namely by the

The clamping screw 89 is screwed into the screw sleeve 86, the spring 91 is supported on the end face 58 of the clamping body 53 facing the spring 91. The spring 91 protrudes in front of the end face 58 and cannot be inserted into the Insertion opening 57 of the clamping body 53 is immersed, but is supported on the outer edge area of the insertion opening 57.

The cross bolt 87 can dip into an anti-rotation seat 59 of the clamping body 53, which extends away from the end face 58 along the push-through opening 57 in the direction of the sealing body 54. So when the clamping screw 89 is screwed into the screw sleeve 85 by means of the actuator 90 (its head), the cross bolt 87 dips increasingly into the Verdrehsi cherungsaufnahme 59, while the spring 91 cannot plunge into the through hole 57. The spring 91 is then no longer supported on the transverse bolt 87, but on the end face 58 of the tensioning body 53.

At the other longitudinal end of the tensioning device 80, the head of the tensioning screw 89, namely the support bearing 82, acts on the free end face 60 of the Spannkör pers 52, which faces away from the sealing body 54, so that the sealing body 54 is compressed in a sandwich-like manner by tensioning the tensioning device 80, with the spring force of the spring 91 acts on the sealing body 54 in the sense of tensioning or compressing.

Sections of the transverse bolt 87 protruding transversely in front of the bolt section 84 form contours 93 for locking against rotation, which cannot rotate in the locking for locking receptacle 59 of the clamping body 53. The anti-rotation mount 59 thus forms an anti-rotation counter-contour 61. The anti-rotation mount 59 is designed, for example, as a receiving groove extending parallel to the clamping axis S er, into which the free end areas of the transverse bolt 87 dip or engage and are supported on its side walls.

By adjusting the clamping device 80 from the release position to the clamping position, the distance between the clamping bodies 52, 53 is reduced, whereby the sealing body 54 is compressed in relation to the clamping axis S. As a result, its outer circumference 62 is pressed or displaced radially outward against the inner circumferential wall surface 49 of the respective line lead-through channel 40, whereby the Sealing body 54 rests in the sealing seat on the inner circumference of the cable duct 40.

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

It is advantageous that the screw sleeve 85 has such a longitudinal extent that it completely penetrates the sealing body 54 with respect to the longitudinal axis LD, so that the screw contours of the clamping screw 89 do not come into contact with the push-through opening or the clamping channel 56 of the sealing body 54. As a result, the sealing body 54 is easily displaceable on the outer circumference of the screw sleeve 85 with respect to the clamping axis S.

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

The clamping bodies 52, 53 also have the anti-rotation contour 63 on their outer circumferences or outer circumferential surfaces that run parallel to the longitudinal axis LD of the sealing body 50. The clamping bodies 52, 53 have the same contour as the outer circumferential surface 62 in that region of the outer circumferential surface 62 which directly adjoins the clamping bodies 52, 53 with respect to the longitudinal axis LD of the sealing body 54. There both the clamping bodies 52, 53 and that of the sealing body 54 are cylindrical, but not circular cylindrical, but for example oval-cylindrical or elliptical-cylindrical. However, other non-circular or non-circular outer circumferential contours of the clamping body 52, 53 and / or of the sealing body 54, for example polygonal outer circumference contours, would also be possible, which with corresponding and positively matching inner circumferential contours of the inner circumferential wall surface 49 each have one with respect to the Insertion axis E or longitudinal axis LD enable the sealing body 50 to be held in the cable feed-through channel 40 so that it cannot rotate.

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

Thus, the form fit of the sealing body 54 and / or the clamping body 52 and / or 53 on the inner circumferential wall surface 49 ensures a non-rotatable hold with respect to the insertion axis E, while the frictional engagement of the sealing body 54 on the inner circumferential wall surface 49 ensures a frictional hold of the sealing body 54 and thus the Sealing device 50 as a whole in line duct 40.

An insertion path of the sealing device 50 into the cable duct 40 along the insertion axis E is limited, as mentioned, by the end face 48 of the outer circumferential wall 41, on which a support projection 64 in the form of a flange protrudes radially outward in front of the clamping body 52 with respect to the insertion axis E. , strikes. The support projection 64 is annular.

Screw receptacles 65 for the retaining screw 51 are provided on the support projection 64. The screw receptacles 65 are, for example, push-through openings. When the sealing device 50 is inserted into the cable duct 40 and the support projection 64 strikes the end face 48, screw receptacles 65 in alignment with the screw receptacles 47 on the channel bodies 30-39. The longitudinal axes of the screw receptacles 47 and the screw receptacles 65 run parallel to the insertion axis E. Thus, the retaining screw 51 can be inserted or screwed into the screw receptacles 65, 47 in a screwing direction parallel to the insertion axis E, so that the sealing device 50 with force directions parallel to the insertion axis E. fix it to the duct 40. For fixing and centering transversely to the insertion axis E, a form-fit receptacle 66 in the form of, for example, an annular groove, into which the peripheral wall 41 engages, is provided on the support projection 64. The form-fit receptacle 66 comprises, for example, a circumferential wall 67 which extends around the outer circumferential surface of the clamping body 52 and is at a radial distance therefrom, so that the form-fit receptacle 66 is configured, for example, in the manner of a U-shaped receptacle, at the bottom of which the end face 48 To the peripheral wall 41 of the channel body 30-39 can strike.

In the area of the screw domes 47A, the circumferential wall 67 preferably has extension parts 68. The screw domes 47A in conjunction with the extension parts 68 represent a further anti-twist protection of the sealing device 50 relative to the cable duct 40 with respect to the insertion axis E.

The assembly of the sealing device 50 is accordingly simple and effective: the sealing device 50 is inserted into the respective line duct 40 and screwed to the respective channel body 30-39 with the retaining screws 51, so that the sealing device 50 is both secure and non-rotatable with respect to the insertion axis E. is received in the Lei processing duct 40 is secured against displacement. The retaining screws 51 can be conveniently operated by, so to speak, from the front, ie. H. from the free side of the Bo denwand 12 can be actuated.

From this side, from which the conductors L also lead to the distributor housing 10, the actuating members 90 of the clamping devices 80 can also be actuated. Apart from the conductors L, there are no obstacles to the actuation or assembly of the components in the way.

In particular, the spring assemblies 92 are arranged in the interior 13 of the distributor device 5 or the distributor housing 10. So you do not protrude to the outside in front of the distributor housing 10, where they would be a hindrance when assembling the distributing device 5, when equipping with conductors L or the like. Rather, the spring arrangements 92 are arranged in a protected manner in the interior 13, so that they do not get dirty, do not freeze or the like when it is cold, which could in principle impair their spring function or tensioning function with regard to the sealing body 54.

Furthermore, the spring arrangements 92 are arranged at least partially in the line lead-through channels 40, furthermore in spaces between the ribs 12B, 12C of the rib structure 12A. Only a short section of the respective spring 91 protrudes in front of the rib structure 12A. In practice, however, this is not a problem because the conductors L run approximately parallel to the longitudinal extensions of the springs 91 or the tensioning devices 80, at least in the area of the spring arrangements 92.

Depending on the required clamping force or spring force, one or more clamping devices 80 are seen in the sealing devices 50A-50D. The tensioning devices 80 are preferably arranged symmetrically, for example in the case of the sealing device 50A along a main axis of the elliptical cross section of the sealing device 50A, roughly corresponding to the section line BB in FIG. 8, or in the case of the sealing device 50B along the section line DD in FIG In the case of the sealing device 50D, the clamping devices 80 are arranged symmetrically, but along a secondary axis of the elliptical cross section of the sealing device 50D. In the case of the sealing device 50C, on the other hand, only a single, centrally arranged tensioning device 80 is provided.

Due to the different configuration of the sealing devices 50A-50D, the distribution device 5 can be individually equipped with conductors L, namely, conductors with different cross-sections, different numbers, etc., is possible. The sealing bodies 54A-54D of the sealing devices 50A-50D have conductor channels 70A-70D for receiving conductors L which, when pushed through the conductor channels 70A-70D, have passage openings 69 of the clamping bodies 52,

53 penetrate and protrude in front of the respective end faces of the sealing devices 50A-50D. For example, only a single conductor channel 70A is provided in the case of the sealing device 50A, ie only a single conductor can be pushed through the sealing device 50A along a through axis DA of the conductor channel 70A. This takes place in the release position of the tensioning devices 80, namely when the sealing body 54 of the sealing device 50A is not compressed, so that a plug-in cross section of the conductor channel 70A is not narrowed by the compression of the sealing body 50. In the sealing device 50B, however, 2 conductor channels 70B are provided, through each of which a conductor L can be pushed, but a conductor that has a smaller cross-section than a conductor that can be pushed through the conductor channel 70B.

In the case of the sealing device 50C, conductor channels 70C are provided through which a conductor L can be inserted along the respective through axis DA of the conductor channel 70C. The conductor channels 70C have even smaller plug-in cross sections than the conductor channels 70B. The conductor channels 70C are for example arranged in a ring around the tensioning device 80 next to one another.

In the sealing device 50D conductor channels 70D are provided, for example two conductor channels 70D, which are arranged on opposite sides of the clamping devices 80 along a row axis which corresponds to the main axis of the elliptical cross section of the sealing device 50D. The conductor channels 70D can, for example, have approximately the same plug-in cross section as the conductor channel 70A, since the cross section transverse to the longitudinal axis LD of the sealing device 50D is larger than the cross section of the sealing device 50A. H. accordingly there is space and space for the conductor ducts 70D.

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 of the sealing device 50D can apply greater forces with respect to the clamping axis S than the clamping devices 80 of the sealing device 50A. Correspondingly, for example, the tensioning anchors 81 of the sealing device 50D have larger cross-sections than the tensioning anchors 81 of the sealing device. Device 50A and / or springs 91 are provided in the sealing device 50D with a greater spring force than in the sealing device 50A.

The sealing bodies 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 cal material of the sealing body 54A-54D has a hardness of at least 10 Shore A, preferably a hardness in a range of about 15 Shore A to 25 Shore A, in particular about 20 Shore A.

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

Conductor channels 70B of the sealing bodies 54B, 254B can be geometrically identical, so that, for example, identical or similar constriction contours, which will be explained below, are provided one behind the other. However, it is also possible for the softer sealing body 54B to have a constriction contour which narrows the conductor channel 70B to a greater extent than the harder sealing body 254B.

If the conductor ducts 70A-70D, which are generally referred to below as conductor duct 70, are not used, i.e. no conductor L is plugged in, closure bodies 180A, 180B, 180C, 180D are preferably inserted, which are hereinafter generally referred to as closure bodies 180 so that the in the sealing Seat-tensioned sealing device 50 and / or the sealing body 54 in the compression position tightly closes the respective conductor channel 70 by the inner walls of the conductor channel 70 of the sealing body 54 resting tightly on the outer circumference of the closing body 180. It should be noted here that the closure body 180 can also only partially bear against the inner contour of the conductor channel 70 with respect to its longitudinal extent in a sealing manner in order to seal the conductor channel 70 tightly. In particular in the tensioned position, a respective closure body 180 closes the conductor channel 70 in which it is received tightly.

Head L, which are inserted into the conductor channel 70, are tightly seated in the tensioned position of the sealing body 54 and held in the conductor channel 70 so as to be fixed against sliding ver with respect to the insertion axis DA. If, however, the tensioning devices 80 are not yet in the tensioning position, the conductors L in the respective conductor duct 70 are displaceable with respect to the insertion axis DA, but so to speak sluggishly displaceable, so that they are held in the respective conductor duct 70 with a predetermined holding force so that they cannot move with respect to the insertion axis DA ten are.

For this purpose, a narrowing contour 71 is provided on the respective conductor channel 70. The narrowing contour 71 is, for example, like an hourglass in cross section. The constriction contour 71 has inclined surfaces 72 inclined to one another, between which an apex section 73 is arranged. At the apex section 73, the narrowing contour 71 delimits the smallest plug-in cross section of the conductor channel 70.

Cylindrical insertion sections 74, for example, are provided on the longitudinal end regions of the conductor channel 70, which are provided on the opposite end faces of the sealing body 54. A plug-in cross section of the cylindrical insertion sections 74 and a plug-in cross section of the passage openings 69 of the clamping bodies 52, 53 are identical. The clamping bodies 52, 53 therefore do not cover the plug-in cross-sections of the conductor ducts 70 and do not protrude into them in the sense of a support either. The clamping bodies 52, 53 act on the sealing body 54 in areas next to the plug-in cross-sections of the conductor channels 70. Displacement cavities 75 are provided on the outer circumferential surface 62 of the sealing body 54. The displacement cavities 75, for example trough-like depressions 76, extend between cylindrical sections 77 at the longitudinal end regions or end regions of the sealing body 54, which the Spannkör pern 52, 53 are opposite. The displacement cavities 75 can extend over the entire outer circumference of the sealing body 54 with respect to the longitudinal axis LD, as illustrated, for example, in the case of the sealing device 50B or 50C.

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

The displacement cavities 75 are free in the release position of the clamping device 80 and when the conductor duct 70 is free, that is to say without a conductor L being inserted into the conductor duct 70. If an operator or fitter now inserts a conductor L into the conductor duct 70, on the one hand the conductor L is held on the constriction contour 71, in particular in the area of the apex section 73, on the other hand at least part of the material of the sealing body 54, which the constriction contour 71 provides, drowned radially outward away from the push-through axis DA, namely into the displacement cavity 75. As a result, the outer circumferential surface 62 is also cylindrical or essentially cylindrical between the cylindrical sections 77, i.e. the outer circumferential surface 62 is already essentially in the release position of the clamping device 80 when the conductor L is inserted into the conductor channel 70 or when the closure body 180 is arranged in the conductor channel 70 flat on the inner circumference of the respective line bushing channel 40 or the inner circumferential surface 49. For example, starting from the contour shown in FIG. 11, when the conductor is not inserted, the outer peripheral surface 62 has the shape shown in FIG. 12, which the outer peripheral surface 62 can have in the area of the push-through openings 56 even when the conductor L is not in the conduit 70. Of course, it is also possible that, for example, the line lead-through channel 40 has a displacement cavity into which a respective sealing body 54 can be deformed. This is indicated in FIG. 4 with the aid of a displacement cavity 75B on the line lead-through channel 40 for the sealing device 50D. It is possible that only the cable duct 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 also 75B are provided could be. The displacement cavity 75B at the same time forms a form-fit contour 49B, into which the sealing body 54 is deformable and received there in a form-fitting manner, such that the sealing body 54 is received in the conductor of the guide channel 40 in a non-displaceable manner with respect to the insertion axis E. The form-fit contour 49B can also, for example, comprise a rib arrangement (not shown) or be formed by it.

The clamping bodies 52, 53 and the sealing bodies 54 are preferably plate-like.

The clamping bodies 52, 53 and the sealing bodies 54 are preferably in one piece or from one piece.

However, a multi-part design is also possible. For example, clamping bodies 52D and 53D are provided in the sealing device 50D, each having two clamping body parts 52D1, 53D1 which are screwed together by screws 53S. 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. The closure bodies 180A, 180B, 180C and 180D, generally referred to as closure bodies 180, are adapted to the respective contours of the conductor channels 70, that is, they are specially designed for the sealing devices 50A, 50B, 50C and 50D. The individual geometric design is made such that the closure bodies 180 are functionally identical in order to close the conductor channel 70 which is not in use when no conductor L is inserted. Identical or identical components of the closure bodies 180A, 180B, 180C and 180D are given the same reference numbers below.

When the sealing devices 50 are tensioned, so to speak, that is to say assume their sealing position because the tensioning devices 80 are tensioned, the closure bodies 180 close the conductor ducts 70 tightly, i.e. they are a substitute for a respective conductor L or close a respective conductor duct 70 instead of a conductor L. When the clamping devices 80 are released and / or the clamping bodies 52, 53 assume their release position, i.e. the sealing devices 50 are basically suitable and ready for inserting conductors L through the conductor channels 70, the closure bodies 180 are advantageously frictionally and / or positively in the Conductor ducts held and must be pulled out of the respective conductor duct 70 with a predetermined force in order to release them so that a conductor L can be inserted or pushed through into the conductor duct 70. The reliable hold of the respective closure body 180 in the conductor channel 70 facilitates the assembly or also the disassembly of further conductors L on the respective sealing device 50 or with the sealing device 50.

The closure bodies 180 have a plug-in section 181 which, for example, is rod-shaped or bolt-shaped and can be pushed through the conductor channel 70 and one or both of the passage openings 69 or inserted into the passage openings 69. A grip section 182, which protrudes in front of the plug-in section 181, is used to grip a respective closure body 180. Between the handle section 182 and the plug section 181, a flange projection 183 is provided, which is provided for supporting on the outer circumferential area of the passage opening 69 of the clamping body 62. A closure section 185 is provided on the plug-in section 181, which in any case serves to engage in the conductor duct 70 and is received in this when the closure body 180 is inserted into the conductor duct 70.

The closure section 185 could quite well have a purely cylindrical shape, i.e. have the same diameter and / or cross section over its entire longitudinal extent with respect to the longitudinal extent of the closure body 180. However, a form-fit receptacle 184 is advantageously provided, into which the narrowing contour 71 can engage. The form-fit receptacle 184 is designed, for example, in the manner of a waist. Inclined surfaces 186 can be provided between the form-fit receptacle 184, which has a smaller diameter and / or cross section than the form-fit section 185, and the closure section 185.

When the closure body 180 is inserted into the conductor channel 70, the constriction contour 71, in particular its apex section 73, protrudes into the interlocking receptacle 184 so that the closure body 180 is positively displaceable with respect to its insertion axis, along which it can be inserted into the conductor duct 70 is held in the conductor channel 70.

The material hardness and / or elasticity of the sealing body 54 in the area of the conductor duct 70 or the conductor ducts 70 is such that even when the clamping device 80 is in the release position, the respective narrowing contour 71 engages the form-fit receptacle 184 with such a force that the ver Closing body 180 is received immovably or essentially immovably in the conductor channel 70 with respect to its respective insertion axis, in any case is held captive in the conductor channel 70.

The sealing device 50D is designed and / or provided for looping conductors through the distribution device 5. For this purpose, the sealing body 54D has, for example, insertion openings 70S which extend inward from the outer circumferential surface 62 to the respective conductor channel 70. Thus, for example, a conductor strand LI or LA of a conductor LX can laterally into the Sealing body 54D are introduced. The insertion openings 70S are designed, for example, as slots which extend with a directional component parallel to the respective through axis DA and / or with a directional component transversely to the respective through axis DA. It is advantageous here that the clamping bodies 52D, 53D can be divided so that their through-openings 69 can be opened laterally for inserting the conductor strands LI, LA.

Thus, for example, the conductor strand LI of the conductor LX can be inserted through one of the insertion openings 70S into the one conductor channel 70 of the sealing body 54D, while another strand LA, which leads out of the distribution device 5, through the other insertion opening 70S into the other conductor channel 70 is inserted at the side. The strands LI and LA are connected to one another by an arcuate section LB which extends on the side of the tensioning body 53D facing away from the sealing body 54D. The conductor LX is thus quasi passed through the interior 13 of the distribution device 5.

In contrast to what is shown in the drawing, however, the curved section LB is advantageously guided and held on a conductor support device 160 so that it does not come into contact with the spring arrangement 92 and / or the tensioning device 80. In particular, with the aid of the ladder support device 160, the arc shape of the arc section LB can advantageously be predetermined. Of course, a conductor L can also be held on the conductor support device 160, which is then spliced, for example in the interior of the distributor housing 10 or the distributor device 5, or the like.

The conductor support device 160 has a base 161 from which the conductor support bodies 163 protrude at an angle. Advantageously, the base 161 and the conductor support bodies 163 form a U-shaped configuration.

The base 163 has through openings 162 for components of the clamping device 80, for example the clamping anchor 81. However, a diameter and / or cross section of the passage openings 162 is dimensioned such that the Springs 91 can be supported on a side of the base 161 facing away from the clamping body 53D.

Each of the conductor support bodies 163 has a support contour 164 for supporting a conductor, for example a conductor strand LI or LA. The support contour 164 is designed, for example, trough-shaped, and extends parallel to the insertion axis DA, along which a respective conductor, for example LI or LA, can be pushed through the conductor channel 70.

The conductor support body 163 has a base body 165, for example a wall body, from which side legs 166 protrude at an angle in order to form a receiving trough or receptacle. The side legs 166 extend parallel to the base body 165 in the longitudinal direction of the conductor support body 163, for example parallel to the through axis DA or with a directional component parallel thereto, but are angled to one another transversely to the longitudinal direction or longitudinal extension.

Fastening contours 167 for fastening a flexible retaining element, for example a cable tie, a wire or the like, are provided on the conductor support body 163, with which a respective conductor, for example the conductor strands LI and / or LA, the conductor LX or the conductor L on the support body 163 can be fastened. The fastening device 167 comprises push-through openings 169 through which such a flexible holding element B1, for example a cable tie, a wire element or the like, can be pushed. Advantageously, hooks 168 are provided on each insertion opening 169, around which a flexible holding element can be looped. Of course, only hooks and no through openings or only through openings and no hooks can be provided.

An intermediate space is formed between the conductor support bodies 163, in which the tensioning anchors 81 including the springs 91 are arranged. Thus, the conductor strands LI and LA do not come into contact with the same when they are supported on the conductor support bodies 163 or the support contours 164. It is advantageous here that the support bodies 163 at their points away from the clamping body 53D turned side protrude further in front of the same than the clamping devices 80. Between the support members 163 there is an intermediate space in which the clamping devices 80 are accommodated. The support contours 164 are provided on sides facing away from one another with respect to the clamping device 80. The clamping device 100 is designed as follows:

The pivot bearing 104 is provided with an end area 105 of the ring body 103 so that end areas of the ring body 103 opposite to the end areas 105 form closure end areas 106 which can be moved towards and away from one another. In the closed position of the clamping ring 101, end faces 107 of the closure end regions 106 abut one another, 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 14, 24, when they are in engagement with the clamping ring 101, held together by the clamping device 100 in a press fit. The two ring bodies 103 and thus in any case the clamping ring 101 have a receptacle 110 for the flange projections 14, 24, which through a bottom wall

108 and side legs 109, which protrude laterally from the bottom wall 108, be limited. For example, the bottom wall 108 and the side legs 109 form a configuration that is U-shaped in cross section. At the end regions 105 of the ring body 103, bearing projections 111 are arranged, which can engage with one another, so that bearing receptacles 119 arranged on the bearing projections 111 are aligned with one another. Then a bearing axle element 112, for example on the bolt body, can be pushed through the bearing receptacles 119 in order to form the pivot bearing 104. The ring bodies 103 are configured identically at the end regions 105, i. H. that, for example, a bearing projection 111 is arranged on each of the side legs 109, one of which is 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. The ring bodies 103 are thus structurally identical in this regard. The closure end regions 106 are also designed in the same way, which is even clearer.

On the outer circumference 114 close to the end regions 105, i.e. close to the pivot bearing 104, pivot stops 113 are arranged which, when the clamping ring 101 is fully open, when the ring bodies 103 are pivoted apart a maximum about the pivot axis of the pivot bearing 104, abut against one another.

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

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

For example, the operating lever 121 of the locking device 120 can optionally be attached to each of the ring bodies 103 by pivotably attaching a bearing element in the form of a tie rod 130 to one ring body 103 or to its ring body 103. In each case, a Schwenkla ger 131 can be produced there, with which the tie rod 130 is pivotably mounted on this annular body 103. The pivot bearing 131 can be produced, for example, using a bearing axle element 133, for example a bolt, which can be arranged on a La geraufnahme 134 of the respective ring body 103, for example a corre sponding bore or passage opening. The bearing axis element 133 also penetrates a bearing receptacle 135 of the tie rod 130, which is aligned with the bearing receptacle 134. Thus, the tie rod 130 is pivotably mounted about a first pivot axis S1 with respect to the annular body 103 on which the pivot bearing 131 is provided. Another pivot bearing is provided between the tie rod 130 and the operating lever 121, namely a pivot bearing 132, which is a second pivot bearing and supports the operating lever 121 pivotably with respect to the tie rod 130 about a pivot axis S2. To produce the pivot bearing 132, a further bearing axle element 133, for example a bolt, is pushed through a bearing receptacle 136 of the tie rod 130 and a further bearing receptacle 129 of the operating lever 121.

To secure the bearing axis elements 133 in the bearing receptacles 129, 136 and / or 119, 135, securing elements 137, for example securing rings, clamping rings or the like can be provided, which can be brought into engagement with the La gerachselementen 133 and these are shiftable with respect to their respective longitudinal axis, the corresponds in the assembled state of the pivot axis S1 or S2, holds on the bearing receptacles 129, 136 or 119, 135

The pivot axes S1 and S2 are parallel to one another. The pivot axes S1 and S2 are at a distance from one another which preferably corresponds approximately to the length of the tie rod 130. Using the pivot axes S1 and S2, the operating lever 121 is pivotably mounted about two pivot axes with respect to the annular body 103 on which the pivot bearing 131 is arranged.

The operating lever 121 has an arm section 122 which runs between a clamping section 123 and a free end region 124. At the free Endbe rich 124 an operating handle 125 is provided for gripping by an operator.

The locking member 126 is arranged between the clamping portion 123 and the arm portion 122. The locking member 126 can therefore be brought into engagement or disengagement from the locking receptacle 127 by pivoting the operating lever 121.

In the present case, the closure receptacle 127 is designed as a sliding receptacle 152 which provides an insertion opening 156 for inserting the closure member 126. The closure member 126 can then be placed in the sliding receptacle 152 between the end stops 153, 154, between which 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 actuating body 150 can be brought into engagement in order to produce the clamping position K. The clamping actuation body 150 at the same time forms the closure member 126 or the closure member 126 provides the clamping actuation body 150.

For example, the closure member 126 / the clamping actuating body 150 comprises actuating cams or actuating projections protruding transversely outward in front of the arm section 122 of the operating lever 121.

Two sliding receptacles 152 are arranged opposite one another on each of the locking end regions 107, into which the locking member 126 or clamping actuating body 150, for example the actuating projections that protrude laterally in front of the operating lever 121, can engage. The displacement receptacles 152 are provided on receptacle legs 138 which protrude radially outward in front of the outer circumference 114 of the annular body 103 on the closure end region 106. A receptacle 128 is provided between each pair of receptacle legs 138, into which, for example, the tie rod 130 and / or the operating lever 121 can engage.

To close the clamping device 100, the closure member 126 is first inserted through the insertion opening 156 into the sliding receptacle 152, that is to say the closure receptacle 127. The sliding receptacle 152 has a T-shaped shape, the longitudinal limb running between the end stops 153, 154 and the middle limb providing the insertion opening 156. So when the closure member 126 and thus the clamping actuation body 150 is received in the sliding receptacle 152, it is between the end stops 153, 154 along the guide contour 155 or the longitudinal leg of the T-shaped receptacle. When the locking member 126 is inserted into the locking receptacle 127, the operating lever 121 initially assumes a release pivoting position LS. In the release pivot position LS, the arm section 122 protrudes from the outer circumference 114 of the clamping ring 101 at a large angle, for example of 90 ° and more. In this case, the clamping actuation body 150 can rest against the release end stop 154 of the sliding receptacle 152.

The operating lever 121 is then wasted from the gripping-back pivot position HS in the direction of a clamping pivot position KS further towards the clamping ring 101, so that the arm section 122 finally runs essentially tangentially to the outer circumference 114 of the clamping ring 101 in the clamping pivot position KS. The clamping actuating body 150 slides from the release end stop 154 in the direction of the clamping end stop 153 and finally rests against this, which can then fulfill its function as a clamping contour 151. The clamping actuating body 150 is in fact at the last Schwenkab section in the direction of the clamping pivot position KS in engagement with the Lö se end stop 154 or the clamping contour 151, so that the operating lever 121 essentially pivots about a pivot axis S3 in this last pivot section, which runs parallel to the pivot axes S1 and S2 through the Klemmbetäti transmission body 150 therethrough. The actuating lever 121 is adjusted to an over dead center position in which it presses the Klemmbetäti supply body 150 into engagement with the clamping end stop 153 with maximum force, whereby the end faces 107 of the closure end region 106 of the ring body 103 are pressed or clamped against each other will.

When can you imagine that the pivoting of an operating lever from an over-center position in the direction of a release position of the clamping is associated with a considerable amount of effort. In particular, the operating lever 121 also serves to move the two locking end regions 106 away from one another from the clamping position K in the direction of the open position O. If in this case, for example, the flange projections 14, 24 are firmly seated in the holding receptacle 110, a considerable operating force is also necessary. The measure explained below provides a remedy here: The operating lever 121 can namely be wasted from the clamping pivot position KS initially by a predetermined angle into the engagement pivot position KS without the closure end regions 106 being moved away from one another as a result. The clamping actuation body 150 slides from the clamping end stop 153 along the guide contour 155 in the direction of the release stop 154. The distance between the end stops 153, 154 provides clearance F for the operating lever 121. In the flint gripping pivot position KS, the free end area 124 is at least so far removed from the outer circumference 114 of the clamping ring 101 that it can easily be gripped from behind by an operator with one finger, in the present case even with several fingers, in order to move the operating lever 121 further in the direction to adjust the release pivot position LS. Since the clamping actuating body 150 actually acts as a release actuating body, namely by acting on the release end stop 154 in the sense of opening the clamping ring 101.

In the clamping pivot position KS, the operating lever 121 is already held in place by its over-center position. An additional or alternative safety measure to over-center fixing is provided by a latching device 115 for latching the operating lever, 121 in the clamping pivot position KS. The latching device 115 comprises, for example, a latching receptacle 116 on the free end region 124 or actuation handle 125 of the operating lever 121 for latching engagement of a latching projection 117 which is arranged in a stationary manner on the clamping ring 101. For example, a latching projection 117 is arranged on each of the two closure end regions 106, that is to say on each ring body 103. The latching projection 117 is provided on a projection 118 protruding radially outward in front of the outer circumference 114 of the clamping ring 101.

The latching projection 114 can, for example, be resilient and / or the operating lever 121 can be resilient in order to bring the latching device 115 into engagement or disengagement.

It is also possible, however, for the locking projection 114 to be closed by pivoting the free end region 124 of the operating lever 121 about one of the axes S1-S3 right-angled axis out of engagement or into engagement with the locking receptacle 116 can be brought. With such an operator action, the latching projection 117 can be hooked into the latching receptacle 116, so to speak.

The clamping ring 101 of the clamping device 100 delimits an essentially circular or exactly circular clamping receptacle 102. Of course, a different geometry can also be implemented in a clamping device, which is clear from the clamping device 100B. The clamping device 100B has a clamping ring 101B with ring bodies 103B which delimit an essentially rectangular clamping receptacle 102B, but whose corner regions are rounded. The ring bodies 103B connect components such as the

Pivot bearing 104 and the locking device 120 are structurally identical or identical in the Klemmvor directions 100, 100B.
