Description

[0001] The invention relates to a clamping device for a distribution device, in particular a splice sleeve, according to the preamble of claim 1.

[0002] Such a clamping device is known, for example, from JP 2012 / 097859 A.

[0003] To adjust the clamping device between the clamping and open positions, the operating lever is pivoted. In the clamping pivot position, the operator must grasp the operating lever and move it toward the release pivot position. Experience has shown that the operating lever is relatively difficult to grasp.

[0004] It is therefore the object of the present invention to provide a clamping device that is easy to handle.

[0005] To achieve this object, a clamping device according to the technical teaching of claim 1 is provided.

[0006] To achieve the object, a distribution device, in particular a splice sleeve, is further provided with 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, wherein the distributor device has a clamping device according to the invention for holding the housing base and the housing cover against one another when they abut one another with their end faces.

[0007] The basic idea is that the operating lever can be adjusted from the clamping pivot position without requiring any particular effort. The operating lever can be adjusted to the rear-grip pivot position with minimal force due to the free movement. This is because the clamping actuator does not exert any force toward the open position of the clamping device or force that would move the locking end sections away from each other during the adjustment of the operating lever from the clamping pivot position to the rear-grip angle position.

[0008] Preferably, the clamping actuating body can be adjusted from the rear-engaging pivot position to the release pivot position by actuating the operating lever to actuate the locking end regions of the ring bodies away from each other into the release position of the clamping ring. Starting from the rear-engaging pivot position, the operating lever thus causes the clamping device to be adjusted from the clamping position to the open position.

[0009] It is advantageous if the clamping contour is arranged on a sliding receptacle in which the clamping actuating body is slidably received, wherein the clamping actuating body abuts against opposing end stops of the sliding receptacle in the clamping position and in the release position, and a distance between the end stops provides the free travel for the operating lever, wherein the clamping actuating body can be adjusted from the end stop associated with the clamping position to the end stop associated with the release position without actuating the locking end regions away from one another. Although the clamping actuating body is accommodated in the sliding receptacle, it can be moved there with little force along the adjustment path associated with the free travel or forming the free travel. The sliding receptacle is preferably arranged on one of the annular bodies.However, it is also possible that the sliding mount is arranged on the operating lever or on another component of the clamping device that is movable relative to a ring body.

[0010] For example, the sliding mount is designed as an elongated hole. The sliding mount can have a curved or straight profile. In the distance between the end stops, a straight guide contour or an arcuate guide contour can be provided for the clamping actuator.

[0011] A preferred geometric concept, for example, provides for the sliding receptacle to have a T-shaped configuration. A central leg of this sliding receptacle is, for example, open, so that the clamping actuator body can be inserted into and removed from the sliding receptacle through this leg.

[0012] While it is fundamentally possible for the clamping actuating body to be only motion-coupled to the operating lever, but to be a separate body, it is preferred, however, for the clamping actuating body to be arranged on the operating lever, in particular in a fixed position. For example, one or more projections are provided on the operating lever to provide the clamping actuating body(s). For example, projections protrude on opposite sides in front of the operating lever, forming one or more clamping actuating bodies.

[0013] In principle, it is possible to provide a locking device for closing the annular body, which is separate from the clamping mechanism already explained or yet to be explained. However, it is preferred if the clamping actuating body forms a locking member for engagement with a locking receptacle, wherein the locking member is movably mounted on one annular body and the locking receptacle is fixedly arranged on the other annular body.

[0014] It is advantageous if the closure receptacle has an opening through which the closure member can be inserted into the closure receptacle and removed from the closure receptacle, so that the closure member can be removed from the closure receptacle and the closure end regions of the ring bodies can be moved away from one another.

[0015] In addition to their clamping function, the clamping actuating body and the clamping contour can also perform a bearing function. Preferably, when the clamping actuating body is in engagement with the clamping contour, the clamping actuating body and the clamping contour form a pivot bearing and / or sliding bearing for the operating lever. For example, the clamping actuating body is rotatable on the clamping contour. In particular, the two aforementioned end stops of the sliding receptacle can be designed as rotary bearing receptacles for the clamping actuating body. For example, the clamping actuating body is round on its outer circumference and engages in the end stops designed as round rotary bearing receptacles. The distance between the end stops of the sliding receptacle provides a displacement path for the clamping actuating body and thus a sliding bearing for the operating lever.

[0016] It is preferred if the operating lever is arranged on a tie rod or bearing element, wherein the tie rod or the bearing element is pivotally mounted on a first pivot bearing about a first pivot axis relative to the annular body supporting the operating lever, and the operating lever is pivotally mounted on the tie rod or the bearing element about a second pivot axis. The tie rod or the bearing element represents a bearing member that pivotally supports the operating lever, so to speak, along two axes. The tie rod or the bearing element preferably has an elongated and / or rod-shaped and / or disc-shaped configuration.

[0017] It is advantageous if the second pivot bearing is arranged between the clamping actuating body and the free end area of ​​the operating lever.

[0018] The aforementioned embodiment, in which the operating lever is pivotally mounted about two pivot axes, naturally results in the following embodiment. However, it is also possible for this to be implemented with a clamping actuating body that is not arranged on the operating lever or pivotally mounted on the operating lever. Thus, it is advantageous if the clamping actuating body is pivotally mounted on the one annular body about two separate, parallel pivot axes. In particular, the multiple pivot axes enable the clamping actuating body to provide the clearance for the operating lever.

[0019] According to the invention, the annular bodies are symmetrically constructed and identical at their closure end regions, and a clamping contour and a bearing, in particular a pivot bearing, for supporting the clamping actuating body are arranged at each closure end region, so that the clamping actuating body can be movably mounted and captively arranged on one or the other annular body, as desired. Thus, depending on the installation situation, the operating lever can be arranged on one or the other annular body.

[0020] A preferred embodiment provides that the annular bodies of the clamping ring are pivotally mounted to one another by a pivot bearing at their end regions opposite the closure end regions. Thus, the two annular bodies can enclose the distributor housing like clips. It should be noted at this point that additional annular bodies or annular segment bodies can also be provided between the two annular bodies described above.

[0021] The clamping ring can have a substantially round or oval clamping receptacle. However, it is also possible for the clamping ring to define a substantially rectangular clamping receptacle, for example, particularly with rounded corners.

[0022] The following measure is advantageous for holding the distributor housing. It is advantageous that the clamping ring has a holding receptacle that is open toward the clamping receptacle, in particular U-shaped in cross-section, for engagement with holding projections, in particular flange projections, of the housing base and the housing cover.

[0023] Furthermore, it is advantageous if the clamping device for locking the operating lever in the clamping pivot position has a locking device that has locking elements arranged on the operating lever and one of the annular bodies, which are locked together when the operating lever is in the clamping pivot position. For example, a locking receptacle can be provided on the annular body and a locking projection on the operating lever, in particular its free end area.

[0025] An optical fiber distribution housing 10 of a distribution device 5 has a housing base 11 closed by a housing cover 15. The housing base 11 has a bottom wall 12 that forms a floor of the distribution housing 11. The distribution device 5 forms, for example, a splice closure 6 that can be used in harsh environmental conditions, for example, in cable ducts, etc.

[0026] The housing cover 15 is designed in the manner of a cover hood 16. The housing cover 15 has an elongated shape and extends along 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 longitudinal ribs on opposite sides, which run parallel to the longitudinal axis and extend to a cover wall 19 of the housing cover 15. The cover wall 19 is opposite the base 12 of the distributor housing 11.

[0027] The housing cover 15 and the housing base 11 define an interior space 13 that is sealed against environmental influences. The interior space 13 extends along the longitudinal axis LG between the housing cover 15 and the base 12 and is circumferentially delimited by the peripheral wall 17.

[0028] 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 annular. At least one sealing projection 21 and / or 22 engages in a sealing receptacle of the housing cover 15 (not visible in the drawing) or bears against an end face of the housing cover 15. Advantageously, a particularly elastic sealing ring 23, e.g., an O-ring, is arranged between the sealing projections 21, 22, e.g., in a sealing receptacle formed by a gap between the sealing projections 21, 22.

[0029] Sealing contours of the sealing arrangement 20 can be brought into engagement with one another by a plug-in movement of the housing cover 15 and the housing base 11 parallel to the longitudinal axis LG in order to tightly seal the interior space 13 against environmental influences.

[0030] Annular flange projections 14, 24 project radially outwards in front of the housing base 11 and the housing cover 15, which, when the housing base 11 is covered by the housing cover 15, i.e. when the housing cover rests against the housing base 11, lie opposite one another and in particular lie flat against one another.

[0031] The sealing arrangement 20 is provided on opposite end faces of the flange projections 14, 24. For example, the sealing ring 23 rests against the flange projection 24.

[0032] The flange projections 14, 24 are held together by a clamping device 100. The clamping device 100 has a clamping ring 101 suitable for enclosing the distributor housing 10. The clamping ring 101 encloses a clamping receptacle 102, each half of which is bounded by an annular body 103. The annular bodies 103 are pivotally mounted on one another by a pivot bearing 104, so that the annular bodies 103 can be pivoted away from one another and toward one another to open or close the clamping receptacle 102. A locking device 120, which can be operated using an operating lever 121, is provided for opening or closing the clamping device 100.

[0033] A support 25 projects from the floor wall 12 into the interior space 13, on which support receptacles 26 for distribution modules or distribution cassettes 27, for example, so-called splice cassettes, are arranged. The distribution modules or distribution cassettes 27 are preferably pivotably mounted on the support receptacles 26, so that they are easily accessible for installing conductors. Fig. For example, Figure 3 shows two distribution modules or distribution cassettes 27 pivoted away from each other. The distribution cassettes 27 can be held in a pivoted position toward the carrier 25, for example, by a band 25A.

[0034] Next to or on the holding receptacles 26, conductor guide elements 28 are preferably arranged, through which a conductor L, shown in dashed lines in the drawing, can be guided.

[0035] The distribution modules 27 have, for example, connecting plugs 29 that can be connected to individual optical fibers (not shown in the drawing) contained in the conductor L. Plugs (not shown in the drawing) that are also connected to conductors L2 running in the interior of the distribution device 15 can be inserted into the connecting plugs 29. The conductors L2 form, for example, components of so-called patch cables. However, it is also possible for conductors L introduced into the interior 13 to be or are directly connected to one another, for example by splicing, in particular on a distribution module 27B designed as a splice cassette.

[0036] The conductor L and other conductors are routed through the housing base 11 into the interior 13, which is sealed against environmental influences by the housing base 11 and the housing cover 15. Furthermore, other sealing measures have been implemented, which will become more apparent below.

[0037] On its side facing the interior space 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 ribbed grid, which stiffens the bottom wall 12. Furthermore, the rib structure 12A supports a base 25B of the support 25. On the base 25B, in particular on the side of the support 25 facing the bottom wall 13, hooks or similar other holding elements 25C for guiding and holding the ladder L are advantageously provided.

[0038] On the side facing away from the interior space 13, 12 channel bodies 30, 31, 32, 33, 34, 35, 36, 37, 38, 39 are arranged on the bottom wall, forming a channel body arrangement. Channel bodies 30-39 are tubular and each have a cable feedthrough channel 40. The cable feedthrough channels 40 have inner circumferential geometries that depend on the cross-section or inner circumferential geometry of the respective channel body 30-39. However, for the sake of simplicity, they are each referred to as a cable feedthrough channel 40.

[0039] A respective channel body 30-39 has a tubular, substantially cylindrical peripheral wall 41, on the free side of which, facing away from the bottom wall 12, i.e. a free end region 43, an end wall 42 is arranged.

[0040] Fig. Figure 5 shows the housing base 11 in its initial state, so to speak, i.e., when the distribution device 5 is not yet equipped with conductors. In this case, the free end faces or end regions 43, where the end walls 42 are provided, are still closed by the end walls 42.

[0041] For equipping, so to speak cabling, the distribution 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.

[0042] For easier and more precise positioning of the cutting tool T in a cutting area between the respective end wall 42 and the peripheral wall 41, recesses 44, for example steps, are provided. Thus, the cutting tool T can, for example, cut off the end wall 42 while supported along the end face of the respective peripheral wall 41. The cutting tool T is, for example, a cutting tool, a saw, an oscillating tool, or the like.

[0043] The so-called edge-side channel bodies 30, 33, 34, 37, 38 and 39 are readily accessible from the outer peripheral region or outer edge region 45 of the housing base 11 with the separating tool T, so that the end walls 42 of these aforementioned channel bodies can be easily separated from the tubular body, i.e. the peripheral wall 41, of the channel body 30, 33, 34, 37, 38 and 39.

[0044] But also the channel bodies 31, 32, 35, 36 arranged so to speak in the middle or in a central area 46 of the housing base 11 are readily accessible for the separating tool T, namely in that their free end areas or end faces 43 protrude freely in front of the edge-side channel bodies 30, 33, 34, 37, 38 and 39.

[0045] The end faces or free end regions 43 of the edge-side channel bodies 30, 33, 34, 37, 38, and 39, for example, protrude from the bottom wall 12 by a longitudinal distance A1. In contrast, the end faces of the central channel bodies 31, 32, 35, 36 protrude from the bottom wall 12 by a longitudinal distance A2, which is greater than the longitudinal distance A1 by a difference DA.

[0046] The central channel bodies 31, 32, 35, 36 form a group of four channel bodies in total, with each channel body 31, 32, 35, 36 being arranged in a corner area of ​​an imaginary rectangle. Thus, each channel body 31, 32, 35, 36 is easily accessible to the cutting tool T from the corner area of ​​this imaginary rectangle via a peripheral channel body 30, 33, 34, 37, 38, and 39 arranged adjacent to it.

[0047] When the end walls 42 are removed from the channel bodies 30-39, a plug-in cross-section of their respective cable feedthrough channel 40 is freely available for inserting sealing devices 50A, 50B, 50C, 50D.

[0048] The sealing devices 50A, 50B, 50C, 50D are functionally similar, which is why they are also generally referred to as sealing device 50 in the following description.

[0049] The sealing devices 50A, 50B, 50C, 50D differ, for example, in terms of their outer peripheral geometry, the number of conductors that can be passed through the respective sealing device 50A, 50B, 50C, 50D, etc. The sealing devices 50 can be inserted along insertion axes E1, E2, E3, E4, E5, E6, E7, E8, E9 into the cable feedthrough channels 40 of the channel bodies 30-39 and then lie tightly against a respective inner peripheral wall surface 49 of a channel body 30-39.

[0050] Furthermore, the sealing devices 50 can be supported on end faces 48 of the peripheral walls 41 of the channel bodies 30-39, so that these end faces 48 provide longitudinal stops for the sealing devices 50 with respect to the respective insertion axes E1, E2, E3, E4, E5, E6, E7, E8, E9.

[0051] The plug-in axes E1, E2, E3, E4, E5, E6, E7, E8, E9 are hereinafter referred to collectively as plug-in axis E.

[0052] The insertion axes E run parallel to one another, preferably also parallel to the longitudinal axis LG of the distributor housing 10. Thus, all end regions or end faces 43 and accordingly all cable feedthrough channels 40 are accessible from the same side in order to insert conductors, for example the conductor L and other conductors not shown, through the cable feedthrough channels 40 into the interior 13 in order to implement the distribution measures there, for example using the distributor modules 27, for example to splice optical fibers and connect them to other optical fibers.

[0053] The end faces 48 of the cable feedthrough channels 40 or the peripheral walls 41 support the sealing device 50 with a force direction K1 parallel to the insertion axis E against a movement in the direction of the interior space 13 on the respective cable feedthrough channel 40.

[0054] 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 bosses 47A, which project radially outward, i.e., on the outside of a respective cable feedthrough channel 40, in front of the peripheral wall 41.

[0055] The screw domes 47A preferably provide anti-rotation counter-contours for the sealing devices 50, which hold the sealing device 50 in the cable feedthrough channel 40 in a rotationally secure manner against a rotation VD with respect to the insertion axis E.

[0056] However, the main function of the screw receptacles 47 is that retaining screws 51 screwed into the screw receptacles 47 hold the sealing device 50 in the respective cable feedthrough channel 40 in a displacement-resistant manner with respect to the insertion axis E and / or with respect to a force direction K2 away from the interior space 13. Preferably, the retaining screws 51 also hold the sealing device 50 in its cable feedthrough channel 40 with respect to the force direction K1.

[0057] The inner peripheral wall surfaces 49 are designed as anti-rotation counter-contours 49A for holding and / or supporting the sealing devices 50 in a rotationally secure manner with respect to the insertion axis E. The inner peripheral wall surfaces 49 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 peripheral wall surfaces 49.

[0058] 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 pairs of 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, even if the clamping bodies and sealing bodies differ geometrically from one another but have a functionally similar structure.

[0059] The clamping bodies 52, 53 have through-openings 55, 56 for the insertion of clamping devices 80, namely clamping anchors 81. The through-openings 55, 56 are aligned with through-openings 57 of the sealing bodies 54, so that the clamping anchors 81 can be pushed through the aligned through-openings 55-57 in order to clamp the clamping bodies 52, 53 relative to one another along a clamping axis S, which runs parallel to a longitudinal axis LD of a respective sealing device 50. This compresses the sealing body 54, which is sandwiched between the clamping bodies 52, 53.

[0060] The tension anchors 81 have a support bearing 82 and an abutment 83 at their longitudinal end regions, between which a bolt section 84 extends. The bolt section 84 comprises screw sleeves 85, 86, which are inserted into one another at one of their longitudinal ends and connected to one another by a cross bolt 87, and each have a screw receptacle at their opposite, free longitudinal ends. A longitudinal axis of the cross bolt 87 runs transversely, in particular at right angles, to the tension axis S. The cross bolt 87 is, for example, inserted through aligned bores 87A of the screw sleeves 85, 86 and fixed in these, e.g., by pressing or gluing.

[0061] An abutment screw 88 is screwed into the screw sleeve 85, the screw head of which provides the abutment 83.

[0062] A clamping screw 89 is screwed into the screw sleeve 86, the head of which provides an actuating member 90 and the support bearing 82. Arranged on the head of the clamping screw 89 is, for example, a Phillips-head contour or similar other driving contour for a tool, in particular a screwing tool, with which the clamping screw 89 can be screwed into or unscrewed from the screw sleeve 86 in order to adjust the clamping device 80 from a released position to a clamped position and vice versa.

[0063] In principle, it would of course be possible for the abutment screw 88 to also be actuated for tensioning purposes. In the present exemplary embodiment, however, it is provided that the abutment screw 88 is essentially screwed only once, namely to tension a spring 91 of a spring arrangement 92 between, on the one hand, the head of the abutment screw 88 and, on the other hand, the cross bolt 87 projecting in front of the screw sleeves 85, 86. The spring 91 is penetrated by the bolt section 84. The spring 91 is, for example, a helical spring. The spring 91 is, so to speak, pre-assembled and / or pre-positioned by mounting it with the abutment screw 88 on the tensioning device 80 or the tensioning anchor 81.

[0064] It is therefore possible that, in the released position of the clamping device 80, the spring 91 is supported only or exclusively on the abutment 83 / the head of the abutment screw 88 and the cross bolt 87. However, when the clamping device 80 is adjusted from its released position to the clamped position, namely by screwing the clamping screw 89 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 penetrate into the through-opening 57 of the clamping body 53, but is supported on the outer edge region of the through-opening 57.

[0065] The cross bolt 87 can be inserted into an anti-rotation receptacle 59 of the clamping body 53, which extends from the end face 58 along the through-opening 57 toward the sealing body 54. Thus, when the clamping screw 89 is screwed into the screw sleeve 85 using the actuating member 90 (its head), the cross bolt 87 is increasingly inserted into the anti-rotation receptacle 59, while the spring 91 cannot be inserted into the through-opening 57. Then, the spring 91 is no longer supported on the cross bolt 87, but rather on the end face 58 of the clamping body 53.

[0066] At the other longitudinal end region of the clamping device 80, the head of the clamping screw 89, namely the support bearing 82, acts on the free end face 60 of the clamping body 52, which faces away from the sealing body 54, so that the sealing body 54 is compressed in a sandwich-like manner by clamping the clamping device 80, wherein the spring force of the spring 91 acts on the sealing body 54 in the sense of clamping or compressing.

[0067] Sections of the cross bolt 87 projecting transversely in front of the bolt section 84 form anti-rotation contours 93, which cannot rotate in the anti-rotation receptacle 59 of the clamping body 53. The anti-rotation receptacle 59 thus forms a counter-anti-rotation contour 61. The anti-rotation receptacle 59 is designed, for example, as a receiving groove extending parallel to the clamping axis S, into which the free end regions of the cross bolt 87 engage or engage and are supported on the side walls thereof.

[0068] 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 with respect 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 cable feedthrough channel 40, whereby the sealing body 54 rests in the sealing seat on the inner circumference of the cable feedthrough channel 40.

[0069] Interlocking screw sections of the screw sleeve 85 and the clamping screw 89 form an adjusting means 94 of the clamping device 80.

[0070] It is advantageous that the screw sleeve 85 has a longitudinal extension such 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 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.

[0071] To prevent the sealing device 50 from twisting in the cable feedthrough duct 40, the sealing body 54 has an outer peripheral surface 62 with a non-circular outer peripheral contour, namely, for example, an oval or elliptical outer peripheral contour, which can engage the correspondingly oval or elliptical inner peripheral contour of the inner peripheral wall surface 49 in a rotationally secure manner with respect to the insertion axis E. Thus, the outer peripheral surface 62 forms an anti-rotation contour 63.

[0072] The clamping bodies 52, 53 also have the anti-rotation contour 63 on their outer circumferences or outer circumferential surfaces, which 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 that directly borders 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 the sealing body 54 are cylindrical, but not circular-cylindrical, but rather, for example, oval-cylindrical or elliptical-cylindrical.However, other non-circular or non-circular outer circumferential contours of the clamping bodies 52, 53 and / or the sealing body 54, for example polygonal outer circumferential contours, would also be possible without further ado, which, with corresponding and form-fitting inner circumferential contours of the inner circumferential wall surface 49, each enable the sealing body 50 to be held in the cable feedthrough channel 40 in a manner that is secure against rotation with respect to the insertion axis E or longitudinal axis LD.

[0073] At this point, it should be mentioned that for a rotation-proof hold of the sealing device 50 with respect to the insertion axis E in the cable feedthrough channel 40, only one rotation-proof contour 63 on one of the bodies 52, 53 or 54 would be sufficient.

[0074] Thus, the positive engagement of the sealing body 54 and / or the clamping bodies 52 and / or 53 on the inner circumferential wall surface 49 ensures a rotationally secure 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 of the sealing device 50 as a whole in the cable feedthrough channel 40.

[0075] As mentioned, the insertion path of the sealing device 50 into the cable feedthrough channel 40 along the insertion axis E is limited by the end face 48 of the outer peripheral wall 41, against which a support projection 64 in the form of a flange abuts, which projects radially outward in front of the clamping body 52 with respect to the insertion axis E. The support projection 64 is annular.

[0076] 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 feedthrough duct 40 and the support projection 64 abuts the end face 48, the screw receptacles 65 are aligned with the screw receptacles 47 on the duct 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 they fix the sealing device 50 to the cable feedthrough duct 40 with directions of force parallel to the insertion axis E.

[0077] For fixation and centering transversely to the insertion axis E, a positive-locking receptacle 66 in the form of, for example, an annular groove is provided on the support projection 64, into which the peripheral wall 41 engages. The positive-locking receptacle 66 comprises, for example, a peripheral wall 67 that extends around the outer peripheral surface of the clamping body 52 and is radially spaced therefrom, so that the positive-locking receptacle 66 is designed, for example, in the manner of a U-shaped receptacle, against the bottom of which the end face 48 of the peripheral wall 41 of the channel body 30-39 can abut.

[0078] In the area of ​​the screw domes 47A, the peripheral wall 67 preferably has extension sections 68. The screw domes 47A in conjunction with the extension sections 68 represent a further anti-twist device of the sealing device 50 relative to the cable feedthrough channel 40 with respect to the insertion axis E.

[0079] The assembly of the sealing device 50 is therefore simple and effective: the sealing device 50 is inserted into the respective cable feedthrough duct 40 and screwed to the respective duct body 30-39 using the retaining screws 51, so that the sealing device 50 is accommodated in the cable feedthrough duct 40 in a manner that is both twist-proof and non-displaceable with respect to the insertion axis E. The retaining screws 51 are conveniently operable by being operable from the front, so to speak, i.e., from the free side of the base wall 12.

[0080] From this side, from which the conductors L also lead to the distributor housing 10, the actuating elements 90 of the clamping devices 80 can also be actuated. Apart from the conductors L, there are no components in the way that would hinder actuation or assembly.

[0081] In particular, the spring assemblies 92 are arranged in the interior 13 of the distribution device 5 or the distribution housing 10. Thus, they do not protrude outward from the distribution housing 10, where they would be a hindrance during assembly of the distribution device 5, during the fitting of conductors L, or the like. Rather, the spring assemblies 92 are arranged in a protected manner within the interior 13, so that they do not become dirty, do not freeze in cold temperatures, or do anything similar, which could fundamentally impair their spring function or post-tensioning function with respect to the sealing bodies 54.

[0082] Furthermore, the spring assemblies 92 are arranged at least partially in the cable feedthrough channels 40, and also in the spaces between the ribs 12B, 12C of the rib structure 12A. Only a short portion of the respective spring 91 protrudes beyond the rib structure 12A. However, this is not problematic in practice because the conductors L, at least in the region of the spring assemblies 92, run approximately parallel to the longitudinal extensions of the springs 91 or the tensioning devices 80.

[0083] Depending on the required clamping force or spring force, one or more clamping devices 80 are provided in the sealing devices 50A-50D. Preferably, the clamping devices 80 are arranged symmetrically, for example, in the sealing device 50A along a main axis of the elliptical cross section of the sealing device 50A, approximately 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. 15. In the sealing device 50D, the clamping devices 80 are also arranged symmetrically, but along a minor axis of the elliptical cross-section of the sealing device 50D. In the sealing device 50C, however, only a single, centrally arranged clamping device 80 is provided.

[0084] Due to the different design of the sealing devices 50A-50D, an individual assembly of the distribution device 5 with conductors L, namely conductors of different cross-section, different number, etc., is possible.

[0085] 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, penetrate through openings 69 of the clamping bodies 52, 53 and protrude in front of the respective end faces of the sealing devices 50A-50D.

[0086] For example, in the sealing device 50A, only a single conductor channel 70A is provided, i.e. only a single conductor can be pushed through the sealing device 50A along a push-through axis DA of the conductor channel 70A. This occurs in the release position of the clamping 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, on the other hand, two conductor channels 70B are provided, through each of which a conductor L can be pushed through, but a conductor that has a smaller cross-section than a conductor that can be pushed through the conductor channel 70B.

[0087] The sealing device 50C is provided with conductor channels 70C, through which a conductor L can be inserted along the respective insertion axis DA of the conductor channel 70C. The conductor channels 70C have even smaller insertion cross-sections than the conductor channels 70B. The conductor channels 70C are arranged next to one another, for example, in a ring around the clamping device 80.

[0088] The sealing device 50D is provided with conductor channels 70D, for example, two conductor channels 70D, which are arranged on opposite sides of the clamping devices 80 along a row axis that 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, ie, there is corresponding space and room for the conductor channels 70D.

[0089] 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. Accordingly, for example, the clamping anchors 81 of the sealing device 50D have larger cross-sections than the clamping anchors 81 of the sealing device 50A and / or springs 91 with a greater spring force are provided in the sealing device 50D than in the sealing device 50A.

[0090] The sealing bodies 54A-54D are one-piece and made of an elastic material, for example, a silicone elastomer, in particular a vinyl silicone rubber (VMQ) or methyl silicone rubber (MVQ). The elastic material of the sealing bodies 54A-54D has a hardness of at least 10 Shore A, preferably a hardness in a range of approximately 15 Shore A to 25 Shore A, in particular approximately 20 Shore A.

[0091] Preferably, each sealing device 50A-50D has only a single sealing body. However, it is also possible for two or more sealing bodies to be arranged one behind the other or next to one another, in particular in a row axis parallel to the longitudinal axis LD of the sealing device 50. For example, two sealing bodies 54B, 254B can be provided, which are arranged one behind the other in the row direction. The sealing bodies 54B, 254B can be made of the same elastic material, but can also have different elastic materials. For example, the sealing body 54B can be made 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.

[0092] Conductor channels 70B of sealing bodies 54B, 254B can be geometrically identical, so that, for example, identical or similar constriction contours are provided one after the other, which will be explained below. However, it is also possible for the softer sealing body 54B to have a constriction contour that narrows the conductor channel 70B to a greater extent than the harder sealing body 254B.

[0093] When the conductor channels 70A-70D, which are generally referred to below as conductor channel 70, are not used, i.e. no conductor L is inserted, dummy bodies BK are preferably inserted so that the sealing device 50 clamped into the sealing seat 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 tightly abutting the outer circumference of the dummy body BK.

[0094] Accordingly, conductors L inserted into the conductor channel 70 are also held in the clamped position of the sealing body 54 in a non-seated manner and are held in the conductor channel 70 in a manner that is fixed relative to the insertion axis DA. However, if the clamping devices 80 are not yet in the clamped position, the conductors L in the respective conductor channel 70 are indeed movable relative to the insertion axis DA, but are, so to speak, stiffly movable, so that they are held in the respective conductor channel 70 in a manner that is fixed relative to the insertion axis DA with a predetermined holding force.

[0095] For this purpose, a constriction contour 71 is provided on the respective conductor channel 70. The constriction contour 71 has, for example, an hourglass-shaped cross-section. The constriction contour 71 has inclined surfaces 72 that are inclined relative to one another, between which an apex section 73 is arranged. At the apex section 73, the constriction contour 71 delimits the smallest plug-in cross-section of the conductor channel 70.

[0096] At the longitudinal end regions of the conductor channel 70, which are provided on the opposite end faces of the sealing body 54, cylindrical insertion sections 74 are provided. The plug-in cross-section of the cylindrical insertion sections 74 and the plug-in cross-section of the through-openings 69 of the clamping bodies 52, 53 are identical. Therefore, the clamping bodies 52, 53 do not cover the plug-in cross-sections of the conductor channels 70 and do not protrude into them in the sense of supporting them. The clamping bodies 52, 53 act on the sealing body 54 in regions adjacent to the plug-in cross-sections of the conductor channels 70.

[0097] Displacement cavities 75 are provided on the outer peripheral 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 are opposite the clamping bodies 52, 53. The displacement cavities 75 can extend over the entire outer circumference of the sealing body 54 relative to the longitudinal axis LD, as shown, for example, in the sealing device 50B or 50C.

[0098] It is also possible for the displacement cavities 75 to extend only over a partial circumference or angular range of less than 360° around the outer circumference of the sealing body 54. For example, in the sealing body 54 of the sealing device 50A in the embodiment of the Fig. 7 and Fig. 8 exemplary displacement cavities 75A of this type are present. However, a trough-like constriction over the entire outer circumference of the respective sealing body 54 is also preferred in the sealing device 50A, as for example in Fig. 13 shown.

[0099] The displacement cavities 75 are free in the release position of the clamping device 80 and when the conductor channel 70 is free, i.e. without a conductor L being inserted into the conductor channel 70. If an operator or fitter now inserts a conductor L into the conductor channel 70, on the one hand the conductor L is held at the constriction contour 71, in particular in the area of ​​the apex section 73, but on the other hand at least a part of the material of the sealing body 54, which provides the constriction contour 71, is drowned radially outwards away from the through-hole axis DA, namely into the displacement cavity 75. As a result, the outer circumferential surface 62 also becomes cylindrical or substantially cylindrical between the cylindrical sections 77, i.e.When the conductor L is inserted into the conductor channel 70 or the dummy body BK is arranged in the conductor channel 70, the outer circumferential surface 62 already lies substantially flat against the inner circumference of the respective cable feed-through channel 40 or the inner circumferential surface 49 in the release position of the clamping device 80.

[0100] For example, the outer peripheral surface 62 then has, starting from the Fig. 11 shown contour with the conductor not plugged in the Fig. 12, which the outer peripheral surface 62 can have in the region of the through-openings 56 even when the conductor L is not located in the cable duct 70.

[0101] Of course, it is also possible that, for example, the cable feedthrough channel 40 has a displacement cavity into which a respective sealing body 54 can deform. This is indicated in Fig.4 using a displacement cavity 75B on the cable feedthrough channel 40 for the sealing device 50D. It is possible that only the cable feedthrough channel provides a displacement cavity and no displacement cavity is provided on the sealing body, but also that the sealing body and the conductor of the guide channel have corresponding displacement cavities, so that, for example, the displacement cavities 75 (or 75A) and 75B can be provided.

[0102] The displacement cavity 75B simultaneously forms a positive-locking contour 49B, into which the sealing body 54 is deformable and is received there in a form-fitting manner, such that the sealing body 54 is received in the conductor of the guide channel 40 in a displacement-resistant manner with respect to the insertion axis E. The positive-locking contour 49B can also, for example, comprise or be formed by a rib arrangement (not shown).

[0103] 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 integral or made of one piece.

[0104] However, a multi-part design is also possible. For example, the sealing device 50D includes clamping bodies 52D and 53D, each comprising two clamping body parts 52D1, 53D1, which are screwed together by screws 53S. The clamping body parts 52D1, 53D1 are, for example, plate-like. The screw axes of the screws 53S run transversely to the longitudinal axis LD of the sealing device 50D.

[0105] The clamping device 100 is designed as follows: The pivot bearing 104 is provided at an end region 105 of the annular body 103, so that end regions of the annular body 103 opposite the end regions 105 form closure end regions 106 that can be moved toward and away from each other. 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 engaged with the clamping ring 101, are held against one another in a clamping fit by the clamping device 100.

[0106] The two annular bodies 103, and thus at least the clamping ring 101, have a receptacle 110 for the flange projections 14, 24, which is defined by a bottom wall 108 and side legs 109 that protrude laterally from the bottom wall 108. For example, the bottom wall 108 and the side legs 109 form a U-shaped configuration in cross-section.

[0107] Bearing projections 111 are arranged at the end regions 105 of the annular bodies 103 and can engage with one another so that bearing receptacles 119 arranged on the bearing projections 111 are aligned with one another. A bearing axis element 112, for example on a bolt body, can then be pushed through the bearing receptacles 119 to form the pivot bearing 104. The annular bodies 103 are configured identically at the end regions 105, i.e., for example, a bearing projection 111 is arranged on each of the side legs 109, one of which is arranged on the inside of the holding receptacle 110 and the other on the free outside, outside the holding receptacle 110, on the respective side leg 109. The annular bodies 103 are thus structurally identical in this respect.

[0108] The closure end areas 106 are also designed identically, which becomes even clearer.

[0109] 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 strike each other in the fully opened state of the clamping ring 101, when the ring bodies 103 are pivoted apart maximally about the pivot axis of the pivot bearing 104.

[0110] The closure device 120 is arranged at 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 to close the clamping ring 101 and subsequently 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.

[0111] The closure device 120 can be arranged optionally on each of the ring bodies 103 because, as mentioned, the mechanical design of the ring bodies 103 at the closure end regions 106 is identical.

[0112] For example, the operating lever 121 of the locking device 120 can be selectively attached to each of the annular bodies 103 by pivotally attaching a bearing element in the form of a tie rod 130 to one annular body 103 or to the other annular body 103. A pivot bearing 131 can be produced there, with which the tie rod 130 is pivotally mounted on this annular body 103. The pivot bearing 131 can be produced, for example, using a bearing axis element 133, for example a bolt, which can be arranged on a bearing receptacle 134 of the respective annular body 103, for example a corresponding bore or through-opening. The bearing axis element 133 also passes through a bearing receptacle 135 of the tie rod 130, which is aligned with the bearing receptacle 134. Thus, the tie rod 130 is pivotally mounted about a first pivot axis S1 with respect to the annular body 103 on which the pivot bearing 131 is provided.

[0113] A further pivot bearing is provided between the tie rod 130 and the operating lever 121, namely a pivot bearing 132, which represents a second pivot bearing and pivotally supports the operating lever 121 about a pivot axis S2 with respect to the tie rod 130. To produce the pivot bearing 132, a further bearing axis element 133, for example a bolt, is inserted through a bearing receptacle 136 of the tie rod 130 and another bearing receptacle 129 of the operating lever 121.

[0114] To secure the bearing axis elements 133 in the bearing receptacles 129, 136 and / or 119, 135, securing elements 137, for example retaining rings, clamping rings or the like, can be provided, which can be brought into engagement with the bearing axis elements 133 and hold them securely against displacement with respect to their respective longitudinal axis, which in the assembled state corresponds to the pivot axis S1 or S2, on the bearing receptacles 129, 136 or 119, 135.

[0115] The pivot axes S1 and S2 are parallel to each other. The pivot axes S1 and S2 are spaced apart by a distance that 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 relative to the annular body 103, on which the pivot bearing 131 is arranged.

[0116] The operating lever 121 has an arm portion 122 extending between a clamping portion 123 and a free end portion 124. An operating handle 125 is provided at the free end portion 124 for gripping by an operator.

[0117] The locking member 126 is arranged between the clamping portion 123 and the arm portion 122. Thus, the locking member 126 can be brought into or out of engagement with the locking receptacle 127 by pivoting the operating lever 121.

[0118] The closure receptacle 127 is configured here as a sliding receptacle 152, which provides an insertion opening 156 for inserting the closure member 126. The closure member 126 can then be moved in the sliding receptacle 152 between the end stops 153, 154, between which a guide contour 155 extends.

[0119] 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 engaged to establish the clamping position K. The clamping actuating body 150 simultaneously forms the closure member 126, or the closure member 126 provides the clamping actuating body 150.

[0120] For example, the closure member 126 / the clamping actuating body 150 comprises actuating cams or actuating projections projecting transversely outwardly in front of the arm portion 122 of the operating lever 121.

[0121] At the closure end regions 107, two sliding receptacles 152 are arranged opposite one another, into which the closure 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 sliding receptacles 152 are provided on receiving legs 138 that protrude radially outward in front of the outer circumference 114 of the annular body 103 at the closure end region 106. Between each pair of receiving legs 138, a receptacle 128 is provided, into which, for example, the tension rod 130 and / or the operating lever 121 can engage.

[0122] To close the clamping device 100, the closure member 126 is first inserted through the insertion opening 156 into the sliding receptacle 152, i.e., the closure receptacle 127. The sliding receptacle 152 has a T-shaped configuration, with the longitudinal leg extending between the end stops 153, 154 and the middle leg providing the insertion opening 156. Thus, when the closure member 126, and thus the clamping actuating body 150, is received in the sliding receptacle 152, it is located between the end stops 153, 154 along the guide contour 155 or the longitudinal leg of the T-shaped receptacle.

[0123] When the locking member 126 is inserted into the locking receptacle 127, the operating lever 121 initially assumes a release pivot position LS. In the release pivot position LS, the arm portion 122 is at a large angle, for example, 90° or more, from the outer circumference 114 of the clamping ring 101. The clamping actuating body 150 can rest against the release end stop 154 ​​of the sliding receptacle 152.

[0124] The operating lever 121 is then pivoted from the rear-engaging pivot position HS toward a clamping pivot position KS further toward the clamping ring 101, so that the arm portion 122 ultimately extends in the clamping pivot position KS essentially tangentially to the outer circumference 114 of the clamping ring 101. The clamping actuating body 150 thereby slides from the release end stop 154 ​​toward the clamping end stop 153 and finally rests against it, which can then fulfill its function as the clamping contour 151. The clamping actuating body 150 is in engagement with the release end stop 154 ​​or the clamping contour 151 during the last pivoting section in the direction of the clamping pivoting position KS, so that the operating lever 121 pivots during this last pivoting section essentially about a pivot axis S3 which runs parallel to the pivot axes S1 and S2 through the clamping actuating body 150.In this case, the actuating lever 121 is moved into an over-center position in which it presses the clamping actuating 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 bodies 103 are also pressed or clamped together.

[0125] When can one imagine that pivoting an operating lever from an over-center position toward a clamping release position is cumbersome and requires considerable effort? In particular, the operating lever 121 also serves to move the two locking end sections 106 away from each other from the clamping position K toward the open position O.

[0126] In this case, for example, if the flange projections 14, 24 are firmly seated in the retaining recess 110, considerable operating force is also required. The following measure can remedy this: The operating lever 121 can be pivoted from the clamping pivot position KS by a predetermined angle into the rear-engaging pivot position KS without moving the locking end regions 106 away from each other. In this case, the clamping actuating 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 a clearance F for the operating lever 121. In the rear-engaging pivot position KS, the free end region 124 is at least far enough away from the outer circumference 114 of the clamping ring 101 that it can be easily grasped behind by an operator with one finger, in this case even with several fingers, in order to further adjust the operating lever 121 in the direction of the release pivot position LS.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.

[0127] In the clamping pivot position KS, the operating lever 121 is already held stationary by its over-center position. An additional or alternative safety measure to over-center fixation is provided by a locking device 115 for locking the operating lever 121 in the clamping pivot position KS. The locking device 115 comprises, for example, a locking receptacle 116 on the free end region 124 or an actuating handle 125 of the operating lever 121 for the locking engagement of a locking projection 117, which is fixedly arranged on the clamping ring 101. For example, a locking projection 117 is arranged on each of the two closure end regions 106, i.e., on each ring body 103. The locking projection 117 is provided on a projection 118 projecting radially outward in front of the outer circumference 114 of the clamping ring 101.

[0128] The locking projection 114 may, for example, be resilient and / or the operating lever 121 may be flexible in order to engage or disengage the locking device 115.

[0129] However, it is also possible for the locking projection 114 to be disengaged from or engaged with the locking receptacle 116 by pivoting the free end portion 124 of the operating lever 121 about an axis perpendicular to the axes S1-S3. With such an operating action, the locking projection 117 can be, so to speak, hooked into the locking receptacle 116.

[0130] The clamping ring 101 of the clamping device 100 defines a substantially circular or precisely circular clamping receptacle 102. Of course, a different geometry can also be implemented in a clamping device, as is clearly illustrated by the clamping device 100B. The clamping device 100B has a clamping ring 101B with annular bodies 103B that define a substantially rectangular clamping receptacle 102B, whose corner areas, however, are rounded. The components connecting the annular bodies 103B, for example, the pivot bearing 104 and the locking device 120, are structurally identical or identical in the clamping devices 100 and 100B.

[0131] The invention therefore relates to a clamping device (100) for a distributor device (5), wherein the clamping device (100) comprises a clamping ring (101) with a clamping receptacle (102) provided for enclosing a distributor housing (10) of the distributor device (5), which clamping receptacle is delimited by at least two annular bodies (103) which are mounted so as to be pivotable relative to one another between an open position (O) and a clamping position (K), wherein the clamping ring (101) clamps the distributor housing (10) in the clamping position (K) so that the housing base (11) and the housing cover (15) are held together by the clamping device (100), and for actuating closure end regions (106) of the clamping ring towards one another, a clamping actuating body (150) mounted so as to be movable on one annular body (103) for, in particular, releasably engaging in a clamping contour (151) of the other annular body (103). has,wherein the clamping actuating body (150) is adjustable by an operating lever (121) between a release position (L) and a clamping actuating position, wherein the clamping receptacle (102) assumes its clamping position (K) in the clamping actuating position and its open position (O) in the release position (L), wherein the operating lever (121) is adjusted closer to an outer circumference (114) of the clamping ring (101) in a clamping pivot position (KS) associated with the clamping actuating position than in a release pivot position (LS) associated with the release position (L). It is provided that the operating lever (121) is assigned a free passage (F) so that the operating lever (121) can be pivoted from the clamping pivot position (KS) in the direction of the release pivot position (LS) into a rear-engaging pivot position (HS) while the closure end regions (106) of the ring bodies (103) continue to abut one another,which lies between the clamping pivot position (KS) and the release pivot position (LS) and in which a free end region (124) of the operating lever (121) has a distance from the clamping ring (101) suitable for gripping behind with an operator's finger.
