Description

PROCEDURE AND DEVICE FOR HOLDING AND REPLACING LONG-HAULED OBJECTS DESCRIPTIVE MEMORY The present invention relates to a device and a method for supporting and guiding, in particular driving elongate objects, in particular multiple wire bundles, multiple sheathed wires, bundles of flat strips or multiple flat cables of the type specified in the preamble of the claim 1. A device of this type is already known from DE 196 40 816A1. This known device is divided along the central plane and with each two arched pressure elements which, during their use, engage in a similar manner to rings around the elongate object (bundle of wires or the like). With the aid of suitable clamping devices, the arched pressure elements can be interconnected by applying the desired contact pressure to the elongate object that is surrounded by the elements. Since it is bipartite, this device makes it possible to produce bundles of wires or other bundles of multiple wires automatically, since it is not necessary when this device is used, whether for holding, driving, or the like, that the wire bundles are threaded in regularly closed structures, perhaps eat conventional hoses or rubber clamps, shrinkable tubes with heat or similar. Since the beginning of the industrial production of multiple wire bundles, such as automobile equipment, it has always been considered that it is an indispensable measure that such bundles of wires are made by hand on so-called forming boards. Therefore, in the course of globalization, efforts have been made to change intensive conventional production in terms of work, for example, bundles of wires to low-income countries. As already mentioned, the main reason why such equipment has to be produced by hand is that the individual wires of a bunch of multiple wires must be threaded by hand through annular structures, such as hoses or rubber clamps, tubes Shrinkable with heat, insulating tubes or similar. It is known from document 196 40 816A1 (Figure 7) that the outer circumferences of each of the two parts of the known divisible devices are lined with a part consisting of a soft rubber sleeve, so that the device can be used as a wall passage, because the outer edge of the rubber sleeve can be put into sealing engagement with the inner circumference with an opening extending through the wall. The dividing surfaces of the rubber sleeve are not dimensionally stable in the case of material-saving types, with the effect that after the action of the external forces there will be an opening at least locally in the area of the dividing surfaces, which risks the fluid tightness that is required in the area of the dividing surfaces. Furthermore, it is known from document 196 40 816A1 that the passage of liquids and gases through the spaces between the wires (slants) in the bipartite device area with the help of butyl is effectively avoided. For the purpose of this measure, which will be referred to hereinafter precisely as "water tightness in the longitudinal direction", the individual wires are adhered in parallel to one another on a butyl layer of a so-called adhesive tape and the individual wires connected This adhesive tape is composed of layers in a part of the divided device, so that the individual wires are interposed between the butyl layers. The through opening that is formed between two arcuate pressure elements of the known device is undersized with respect to the wire system provided with butyl adhesive, so that a uniform pressure will be exerted on the wire bundle when the two elements of the wire are joined together. The pressure and the bundles of wires will be firmly pressed in their entirety against the inner wall of the passage opening, so that liquids and / or gases will not pass between the individual wires or between the inner circumference of the wire bundles and the inner surface of bipartite device. It is an object of the present invention to provide improved split devices of the type outlined in the preamble of claim 1.

This object is achieved with the subject of claim 1. The technical progress that can be achieved with the help of the present invention is mainly due to the fact that in its simplest form of the device of the invention, which will be designated as a " "clamp" or "sleeve" in the following text, is capable, because of the sealing and dimensionally stable divider surfaces provided with a connecting section and the pressure section, to retain bundles of multiple wires or the like, hermetically sealed fluids in the desired position, whereby not only the electrical wires, but also the conduits carrying the means can be guided, held and driven with the aid of the inventively divided clamp. Conveyor conduits are, for example, thin hollow bodies that conduct liquids, such as washing liquids, cooling liquids and braking liquids, to their place of use. The inventively designed and divided clamp, comprising at least one pressure section and at least one connection section following said pressure section in the direction of extension of the elongate objects and having dimensionally stable sealing divider surfaces, is capable of replacing the annular or tubular soft rubber clamps that have been in use up to now and to which they can be introduced only by hand bundles of cable or the like in a time-consuming manner.

In a preferred embodiment of the invention, dimensional stability and sealability on the dividing surfaces of the connecting section are ensured, in the sense that the connecting section on its outer side consists of an elastic material (such as EPDM / TPE) comprises an insert of stiffening, for example of PA, in its interior. It is thanks to such structure that the connecting section is dimensionally stable to a sufficient degree, in order to withstand the external forces that are expected during the operation so that in the area of the dividing surfaces of the two halves (parts) of connection there will be no leakage during the operation. The elastic material on the outside of the connection section allows a fluid-tight connection of the outer circumference of the inventive clamp to the edge position of an aperture formed in the wall, ie in principle in all types known today of sleeves or clamps, for example, insert clamps by tension, pressure or push. The preferred embodiment discussed above with a stiffening "skeleton" inside at least the connection section (which, by the way, retains a flexible elastic material) creates a technically useful split rubber band for the first time. If tubular rubber or soft annular clamps, which are known in the art, are longitudinally separated, the two halves can not be reliably and sealably joined together again, because leakage areas of the divider surface would automatically be encountered with the application of forces external. With rigid materials it would perhaps be possible to achieve adequate dimensional stability, but such rigid materials could not ensure the fluid tightness that is sought, which requires an elastic, soft and flexible material. The above discussed embodiment of a stiffening "skeleton" consisting of a rigid plastic material, such as PA, in the connection area of a bipartite clamp is a prior connection of the technically useful divisibility that is achieved with the aid of the invention and for the sealability of the clamp that can be achieved with the aid of the invention. Other preferred embodiments of the clamp are described in the dependent claims 2 to 16. The two clamp parts of the invention, also referred to precisely as "halves" in the following text, are not in contact with each other at the moment when a clamp is inserted. bundle of wires. Next to the insertion of the bundle of wires, the two halves are joined, which comprise a pressure section surrounding the bundle of wires and a connection section next to said pressure section in the longitudinal direction, in the area of its dividing plane. The dividing planes are joined by screwing, interlocking, embracing or in any other suitable manner. The bundle of wires is fixed in the clamp according to the invention by exerting pressure after the two halves have been joined. The following alternatives have been provided for each application of fixing pressure: - light oversize of the diameter of wire bundle in relation to the free diameter of the passage channel formed between the pressure sections joined; - increasing the diameter of the bundle of wires by wrapping in it with a suitable material; - provision of a rubber-like coating on the inner surfaces of the passage channel halves of the two pressure sections, whereby the free diameter of the passage channel can be reduced so that pressure is exerted; - selection of a flexible or semi-flexible material for the passage channel of the pressure sections; possibly such a rubber-like material, flexible or semi-flexible, is provided only in one of the two pressure sections, the material forced to reduce the diameter of the passage channel. As regards the "sealability" mentioned above, a distinction must be made between two cases: 1. fluid-tight seal in the inventive clamp as such, and 2. the so-called water tightness in the longitudinal direction or sealed to the test longitudinal water in the case in which liquids or gases are to be prevented from slipping through the inventive clamp along the surfaces of the individual wires of the bundle of wires or wires or over the insulating sleeves. Accordingly, within the scope of the present invention, "water tightness in the longitudinal direction" designates the ability of the inventive clamp to effectively prevent fluids from passing axially from one side of the clamp to the other side of the clamp. In contrast, within the scope of the present invention, the term "fluid tight seal" does not consider the prevailing conditions within the wire bundle, but the conditions that exist outside the bundle of wires, in particular, can be assured of a wall opening sealing the outer circumference of the connecting section with the help of the clamp. In the clamp according to the invention, the waterproofing in the longitudinal direction can be achieved in the sense that a sealing compound is provided, preferably a butyl compound, as described in DE 44 41 513 A1 or another sealing compound, for example a pressureable gel, a grease, or a suitable sealing compound and adhesive, between the individual wires of the wire bundle or between its insulating sleeves on which it presses immediately after the union of the two halves of clamp. Such application of pressure (constant) is carried out on the sealing compound, according to the invention preferably with the help of the following alternatives: the pressure element sections have a rubber-like lining at least in the area of its passage channels; - the pressure element sections consist, at least in the area of the passage channels, of a plastic material similar to rubber, flexible or semi-flexible, such as a plastic material that is possibly provided in one of the two section elements of pressure of a clamp. Needless to say, the diameter of the wire bundle will be increased when a sealing compound is placed between the wires individual wire bundles or between the insulating sleeves of these individual wires. A bundle of wires having such oversize can be fixed in correct position in the pressure section elements when said pressure element is provided two opposing springs react together with the receiver positions that are formed in the , 0 section of opposite pressure. Such springs ensure that the two clamp halves join centrally. The springs mentioned above serve not only to place a bunch of oversized wires, but also serve as 2 level gauges "to ensure that high enough pressure is exerted on the sealing compound." To this end, a bundle of wires is verified. The diameter is oversized because of the sealing compound contained in the wire bundle, as long as the diameter of the wire bundle is so large that it corresponds to the height of the upper edge of said spring. If the wires are not so large that they reach the upper edges of said opposite springs, the diameter of the wire bundle can be clogged with sealants until the diameter of the bundle of wires (crowded) reaches to the upper edge of the spring.

It is inferred from the foregoing that the clamp that can be divided according to the invention is fluid-tight on all its dividing surfaces and also in its connecting portions with a wall opening. According to a preferred embodiment, water tightness in the longitudinal direction can be achieved by using a sealing compound, possibly in the form of adhesive tape. Furthermore, it goes without saying that the area formed by the pressure elements can be not only straight, but also curved, that is, it can have any desired design. The clamp according to the invention guarantees the following economic advantages: as a result of its divisibility, the conventional operation of stringing time consuming and therefore cost intensive can be dispensed with. This also creates conditions in which simple and complicated wire bundles, such as automobile cable equipment, can be produced automatically. Furthermore, according to the invention, the water tightness in the longitudinal direction does not necessarily have to be created in a separate operation. In addition, the dividable clamp according to the invention can be easily repaired and maintained, because when they are to be located, for example faults, the two halves of the clamp can be separated from one another and inspected from inside the clamp. The clamp which is divided according to the invention and which allows a subsequent opening operation without any problem makes it possible for example to introduce electrical or other additional wires at a later time and also to remove an electrical wire or another originally provided without damaging the clamp as a whole, its tightness to fluids or its water tightness in the longitudinal direction. The water-tight variant in the longitudinal direction of the dividable clamp according to the invention can replace non-divisible rubber sleeves or clamps, together with sealing or shrinkable tube components with the heat consisting of adhesives of the hot melt type or the like , which have been used so far for the purpose of achieving water tightness in the longitudinal direction. Accordingly, costly insertion in bundles of wires or the like (ie through the conventional rubber sleeve and the conventional shrinkable tube) can be dispensed with. As for the method to be created, the aforementioned objective is achieved with the subject matter of claim 17. The technical process that can be achieved with the help of the inventive method is mainly to the fact that they can be supported and guide elongated objects, such as bundles of wires, through a wall opening with the aid thereof, by means of which it is ensured that it is placed and fixed with precision of the elongated object, but it is guaranteed in particular that the two half cases of clamp are connected in a dimensionally stable (proportionally rigid) and fluid-tight manner. Advantageous developments of the invention allow application of a (constant) pressure on the elongate object (bunch of wires), said pressure being exerted on the elongate object providing a slight oversize for the elongated object or cluttering the elongated object or providing a similar inner lining to rubber in the two pressure sections that are to be used. Such permanent pressure acting on the elongate object (bundle of wires), can be exerted by producing the pressure elements of a plastic material similar to rubber, flexible or semi-flexible, in the passage channel area. The method of the invention can also be carried out in such a way that the sealing compound is introduced between the individual wires or the individual wire isolations of a bundle of wires. When acting on this sealing compound, preferably butyl (butyl rubber), with the pressure mentioned above, the bundle of wires is protected with sealing against the passage of liquids or gases with the effect that liquids or gases can not pass through. one side of the bipartite clamp to be used on the other side. The bipartite rubber clamp to be used in the method of the invention is dimensionally stable, ie torsionally rigid, at least in the area of its dividing surface (connecting surfaces) and in addition in a preferred embodiment of the method of agreement. With the invention, use is made of a diameter of the elongate object (bundle of wires) mentioned above and ensures a constant pressure, because the bipartite clamp to be used is equipped with suitable level indicators for this purpose. Other preferred embodiments of the method according to the invention are described in subclaims 18 to 24.

All the embodiments of the clamp according to the invention have in common that they comprise a pressure section that is engageable with a bunch of wires another elongated structure, and that a connecting section comprising an outer circumference that is connectable, at least in part, to a wall is joined to said pressure section in the longitudinal direction (axial direction). The inventive clamp is preferably separated or divided along a central plane, so that each clamp consists of two interconnectable halves of which each comprises a part (for example a half) of the pressure section of a part (for example). example 1 half) of the connection section. In the illustrated embodiments, the division planes of the pressure section and the pressure section and the connection section that joins always extend in the same plane. However, it goes without saying that the division plane of the connection section can have an orientation that differs from that of the division plane of the pressure section. The surface of the passage channel formed by the pressure section can be hard and smooth and consist of polyamide. Alternatively, however, the surface of the through opening may have an additional coating, preferably a soft, elastic material, such as EPDM, TPE, and the surface coated in this manner is either smooth or rib-shaped, as will be described in more detail in the following text. The connection sections that serve to connect the pressure sections of the clamp of the invention to a wall, in particular a wall opening, are dimensionally stable (torsionally rigid) and has a sealing effect, at least in the area of these dividing surfaces (connection surfaces). A special advantage of the clamp of the invention results from the fact that the connecting section is made of an elastic material, such as EPDM, TPE, and a reinforcing material, such as polyamide. It is only thanks to such a combination of materials that a sealing and torsion-free clamp can be obtained, in particular due to the reinforcement shown in Figure 3 in the connection section. In the following description, the terms "parts" and "half" as synonyms for the two half helmets of which the clamp is composed and inventively divided. However, it goes without saying that the two parts of a device according to the invention do not need to have the same size, because it is also possible in principle an angular separating cut through the device, whereby a larger first section would be obtained and a second smaller section. Figure 1A is a view illustrating an assignment of the essential parts and the use of a preferred embodiment of the inventively divided clamp. The clamp consists of two halves (half helmets), namely one upper and one lower. Each half-shell has a pressure element 2a and 2b, respectively and a connection section element 4a and 4b, respectively, which is attached to said pressure element in the longitudinal direction. When the two half-hulls are interconnected as detailed in FIG. 1A, they form an elongated passage channel 5 and a funnel-shaped connection section 4 which joins said channel in the longitudinal direction. A bundle of wires, for example a section of a cable assembly, can be safely received between the two half shells of the clamp, a sufficiently large pressure being exerted in the area of the pressure elements on the bundle of wires to fix the same surely. The dimensionally stable connecting section 4 having a sealing effect can be placed with its outer circumference in sealing engagement with the edge portion of a passage opening in a wall (not shown). The funnel-shaped connecting section 4 consists of two different materials. Beside the pressure elements, the connection section is made of a rigid plastic material, such as PA: This stronger material is surrounded by a non-rigid flexible material, such as EPDM / TPE. A locking edge 12 and a sealing lip 14 are formed on the outer circumference of the non-rigid part. A tongue and groove system 16, 18 is formed in the dividing surfaces of the connecting sections 4a, 4b. Also shown are the vertical springs 8 and the receiving depressions 9 which act in conjunction with the springs. In its operative position, the two half shells are connected to one another in a fixed manner but, if necessary, releasable, the bundle of wires being received between the two half shells in a fixed and reliable manner. Within the scope of the present invention the expression "dividing surfaces" means all those surfaces that are arranged in a dividing plane (the division planes) of the clamp of the invention. To make more specific, "dividing surfaces" are always those surfaces with which the two half helmets are in intimate contact in the interconnected state. In the area of the pressure section, the divider surfaces preferably consist of a rigid plastic material, such as PA, optionally coated with rubber-like materials, such as EPDM / TPE, or an adhesive. In the area of the connecting section 4, the dividing surfaces consist, however, of the material of the non-rigid material mentioned above. The dividing surfaces of the connecting section comprise the tongue and groove system by means of which the two parts of the connecting section can be interconnected in a divisionally stable and sealing manner. Figure 1 B shows a half shell in an inventive clamp embodiment, comprising a pressure element 2a (lower) has connection section element 4a (lower). The pressure element 2 a is here configured in the form of a tubular element. Likewise, the upper pressure element (not shown) is also formed as a tubular element, so that the two pressure elements form a complete tube with a passage channel 5 after they have been joined. The two clamp parts are interconnected by opposing flange elements 6 extending outward in the dividing plane of the pressure elements. Consequently, after the clamping parts have been joined, they touch one another with their dividing surfaces in the area of the dividing plane and through the surfaces of the flange elements 6 which are oriented towards each other. The clamp parts are screwed together through the holes provided in the flange elements 6 or are interconnected differently after a bundle of wires is inserted into the passage channel 5. In addition, each pressure element is provided with Guide element that facilitates the operations of hooking and joining. Such a guide element is shown in Figure 1B. in this embodiment, the pressure element 2a is provided with spring elements 8 which are designed as an extension of the dividing surface of the pressure element. The upper pressure element (not shown) is suitably formed with receiving depressions to which the spring elements 8 insert. In addition, each pressure element 2a is to be provided on a final portion with a section having a smaller cross section in order to exert additional pressure on the bundle of cables to be inserted, by means of which it goes against subtracting the butyl outlet. In addition, this portion of a lower cut (30) has been provided which makes it possible to couple, for example, flexible and ribbed corrugated pipes to protect the bundle of wires. Each pressure element is provided integrally in a die of a connecting section element 4a which has the shape of half funnel. The portion to the narrow funnel is assigned to the pressure element while the pressure of the expanding funnel is oriented away from said element. The connecting section element is formed on the upper pressing element (not shown) so that there is a play opposite, so that the two elements form a connecting section 4 in the form of a full funnel when the two half helmets are joined together. . Preferably, the dividing surfaces of the connecting section element 4a are also formed with a groove and tongue (figure 12) to ensure the fluid-tight connection of the two elements and to allow, at the same time, a more solid connection of said elements. elements. In addition, the divider surfaces can be moistened with an adhesive to provide a particularly firm connection. Gels, grease or similar can be used to ensure that the connection is fluid-tight. The structure of the funnel-shaped connecting section element 4a is shown in FIG. 3. In its interior, the element 4a has a reinforcing element 25. This reinforcement element is integrally made with the pressure element 2a, which comprises preferably of PA, and extends to a predetermined degree to the funnel-shaped structure. The reinforcing element provides the necessary stiffness for the funnel in the narrow funnel portion, while the extending outer funnel portion is made flexible and preferably consists of EPDM / TPE, so that the inner cut provided therein can be locked applying a normal typical force. Such rigidity is a necessary precondition for achieving torsional rigidity in the dividing plane, without which there will be no water tightness in the area of the dividing plane. According to FIG. 2, a locking edge 12 acting in conjunction with a sealing lip 14 is formed on the outer side of the connecting section element 6a on the extending funnel. During its use, the funnel-shaped connecting section 4 is inserted with its outer circumference to a corresponding wall opening whose edge (not shown) is seated sealingly between the locking edge 12 and the sealing lip 14. Figure 4 shows schematically a modality different. The two pressure elements form a hemispherical element which are joined on a dividing surface (not shown) to form a sphere. The two pressure elements are supported on a helmet 3 (see FIG. 7) which makes it possible for the sphere to perform a rotational movement inside the helmet. In addition, the helmet is made integrally with a funnel-shaped connection section 4, the funnel configuration extending to be remote from the helmet 3 being configured. The exact structure of the pressure elements 2a, 2b of the Ifc mode Figures 4,6 and 7 are made apparent by Figures 5A and 5B.

As shown, each of the pressure elements is formed as a hemisphere, the divider surfaces 6a, 6b being joined during use to form a sphere. Each of the dividing surfaces of the hemispheres has a cavity shaped in the manner of a groove that extends over the entire surface to the surfaces of the sphere semirredondas. During use, the two pressure elements are interconnected in such a way that these cavities together form a passage channel 5 which are arranged centrally in the resulting sphere. To simplify the joining operation for the two pressure elements, centering elements are also provided on the surfaces dividers 6a, 6b. As shown, one of the pressing elements comprises the shoulders 7 in the area of the dividing surface 6b. Consequently, the divider surface 6a is provided with the cavities T that coincide with the projections 7 in dimension and arrangement. During use, the shoulders 7 of the pressure element 2a engage the cavities T of the element of pressure 2b, so that the two members are virtually entangled. The pressure elements 2a, 2b are additionally provided with side guiding elements which, during use, guide the bundle of wires during the pressing operation. For this purpose, the guiding elements 8 are formed on the dividing surfaces 6a of the pressure element 2a to directly connect the two longitudinal sides of the slot of the passage opening, the guide elements 8 being exceeded in the form of springs in one direction approximately perpendicular to the dividing surface. The other pressure element 2b is likewise provided on the divider surface 6b with the grooves or depressions 9 which are connected directly to the longitudinal sides of the groove of the passage opening and which coincide with the springs 8 in shape and size. During use, the springs and slots or depressions engage with each other and ensure - apart from an additional guide wire bundle - that reduces pressure elements are locked in an improved manner. After a bundle of wires has been inserted and the two pressure elements 2a, 2b have been joined, the elements are screwed from the outside through the drilled holes that have been provided. The two elements, however, can also be connected by means of adhesives, rivets or other positive connection methods. The joined pressure elements are subsequently received by two half helmets which are formed on the two narrower funnel portions and together form a spherical shell 3. The dimensions of the outer spherical surface and the inner side of the half shell are chosen in such a way that the sphere formed by the elements 2a and 2b can move in the middle helmet. Each half shell is preferably designed in such a way that only about half of the spherical surfaces are covered by the half shell, such that the opening portions subsequently interconnected by a threaded joint or with rivets are exposed. Each half-shell is formed integrally with one half of a funnel-shaped connecting section 4, with the funnel portion extending oriented away from the half-shell (Figure 6). The extending funnel portion is provided on its outer side with a locking edge 12 extending outwardly around the entire circumference of the funnel. In direct vicinity of the locking edge 12, the outer side of the funnel has formed on it a shoulder which also extends over the entire circumference of the funnel. During use, the funnel is secured by the locking edge 12 and the adjacent shoulder in apertures of thin-walled brackets or wall plates. The locking edge is arranged here on one side and the shoulder on the other side of the wall opening. Pressure elements 2a, 2b are preferably made of polyamide. Likewise, the reinforcing portions 25 preferably consist of polyamide. The outer cover of the funnel preferably consists of EPDM, TPE which is provided around the reinforcing element 25. To put the device into operation, a bundle of wires is first inserted into the through opening of one of the pressing elements 2a, 2b only the bundle of wires was dimensioned with respect to the diameter of the through opening. The wire bundle consists of prepared wires which, if water tightness in the longitudinal direction is desired, are embedded in adhesives, and consist, in particular, of a plurality of individual wires or individual insulated wires which are arranged on a adhesive tape in such a way that the individual wires are sandwiched between the individual layers of the adhesive tape. The active layers of the adhesive tape preferably consist of butyl (butyl rubber). Subsequently, the two pressure elements 2a, 2b are combined and pressure is applied to the bundle of inserted cable. If butyl or the like is not introduced between the individual wires, the wires are supported and guided only by the pressure exerted by the two pressure elements of the pressure section. However, if a material, such as butyl, is provided between the wires and between the wires and the inner wall of the through opening, the water tightness in the longitudinal direction is also achieved, so that no moisture can be spread. along the individual wires. Such seal obtained with the help of butyl or the like is also gas tight. The bipartite connecting section according to the invention which is joined to the bipartite pressure section allows a fluid-tight guide, for example, of a bundle of cables through a wall opening. As already served, the outer circumference of the funnel-shaped connecting section acts fluidly in a fluid-tight manner with the wall section surrounding the passage opening, so that the moisture as a result of the longitudinal water-tightness is not It can propagate through the inside of the bundle of wires and as a result of the fluid-tight seal in the area of the outer circumference of the connecting section can not be propagated through the wall opening. As already mentioned, the two pressure elements of the pressure section are positively interconnected by a tongue and groove connection and the two correction section elements of the funnel-shaped connection section are also positively interconnected by a tongue and groove connection after the bundle of wires has been inserted another elongated object into one of the split device halves and the other half is used to close the device. As far as the mode shown in FIGS. 4 to 7 is concerned, it should be noted that the pressing element 2 which are joined to form a sphere is movable in various directions within the hull elements 3 holding the sphere, so that the contrast with the modality according to figures 1 to 3 and the directional orientation of the passage channel 15 is variable. As already mentioned, the device of the invention in its function of "clamp", that is to say of "body in the form of a funnel of insulating material to conduct electric lines through walls or to introduce the same to electrical devices" has a function dual. On the one hand, the clamp ensures that the wall opening through which the bundle of wires passes (bundle of wires) is sealed, as the outer edge of the funnel-shaped connecting section, which is preferably made elastic, it is with a seal that can be connected to the circumferential wall of the opening. On the other hand, the circumferential surfaces that exert pressure on the cable bundle and belong to the passage of the pressure section that joins the connection section in the longitudinal direction ensures that the cable bundle is retained in said passage opening in a manner Slip proof. If butyl or equivalent material provided with other individual wires is providedThe water tightness is achieved in the longitudinal direction, above all, between the individual wires of the bundle of cables and also between the outer surface of the cable bundle and the inner surface of the through opening. Experience shows, however, that sealing measures employing butyl or other suitable sealing compounds tend to lead to brittleness and slight shrinkage over time. Such shrinkage, however, will deteriorate the seal of the bundle of wires unless this shrinkage behavior is taken into account. With the aid of the method described in the following text, in particular with figures 9A, 9B, 10A and 10B, 11 A, 12 to 14, 16 to 18, the collecting of butyl or the like can be compensated in a "self-healing" manner. Figure 8a is a perspective view looking for an elongated object in the form of a section of a bundle of wires. As is known, the wire bundle consists of a plurality of wires each of which is insulated with respect to one another with the aid of the plastic material. A selected section of the surface of the wire bundle is provided with a liner 50 which, for example, is guided around a bundle of wires in the form of at least one winding to increase the cross section thereof. It is thus possible to increase the circumference of the wire bundle of a predetermined section of the wire bundle surface to a desired degree. Along with the embodiment of the clamp of the invention, which will be described in the following text in more detail, such an increase in diameter can be very convenient. For example, when the outer circumference of the wire is not large enough to be retained in the inventive clamp in an anti-slip manner, the diameter of the wire bundle can be increased by wrapping or forming a winding around a pre-selected section of the wire bundle, i.e. to such a degree that the diameter of the pass channel of the clamp is undersized to the bundle of wires lined, so that after the insertion of the lined section of the bundle of wires this will be held with a snap fit in a non-slip manner in the clamp after the lined section of the wire bundle has been inserted. Needless to say, the circumference of the wire bundle can be increased in principle by taking any suitable measures. Figure 8B is a section taken along line AA of Figure 8A, showing the resulting increase in circumference of the wire bundle as a consequence of the liner 50. Needless to say, the waterproofing of the steering can not be achieved. longitudinal in the area of the lining 50 simply taking the measurements illustrated in Figures 8A and 8B, since such winding 50 has no influence on the spaces between the adjacent wires of the wire bundle. The shoulder springs 8 that are assigned to the pressure section elements serve mainly to guide the bundle of wires to be inserted into the clamp halves. When properly dimensioned, however, they can also serve as level indicators to monitor the desired diameter of the bundle of cables to be inserted during assembly. If it is to be made apparent during the assembly that the cable bundle has a diameter that is too small, the filler member, which is known from DE 196 40 816 A1, must be additionally used to increase the overall diameter of the system of cables in the area of the clamp to the desired degree. The aforementioned filling members serve to locally increase the circumference of the wire bundle in cases in which the circumference of the original wire bundle is not sufficient to ensure the necessary contact pressure within the clamp of the invention while the two are joining together. clamp halves. These filling members preferably consist of a flexible elastic material, such as EPDM. Semi-flexible plastic materials, such as PE and PVC, however, have also proved suitable for this purpose. In addition, it has been determined that it is advantageous when these fillers are provided with a liner which preferably has a sticky and therefore sealant effect. The butyl to result be particularly suitable for such purpose. Such filler members that are butyl-lined should preferably be sandwiched between release paper and cut to the desired size. The use of the springs 8 as level indicators indicates that the pressure required to obtain the perfect and permanent water tightness for a bundle of wires and the longitudinal direction can be produced within the clamp. The butyl adhesive tape that is particularly preferred is preferably processed to achieve water tightness in the longitudinal direction, within a temperature range of about 60 ° C. In cases where water tightness in the longitudinal direction is not desired, the diameter can be increased with the help of the liners 50 (FIG. 8A, 8B) and 50 '(FIG. 11B) in bundles of cables whose diameter is undersized . Figures 9A and 9B are a perspective view illustrating the two parts of a split clamp designed according to the invention. The half-shell shown in Figure 9A comprises an upper pressing element 2A and an adjacent element of the connecting section 4A. Thus, the other half shell of the clamp as shown in Figure 9B comprises a lower pressing element 2B joined by a connecting section element 4B. The shoulder springs 8 between which a passageway for a bundle of wires extends along rib-like shoulders 10 are provided on the bottom clamp half shown in Figure 9B. The half-shell shown in Figure 9A comprises two groove-like receiving depressions 9 which are engaged by the springs 8 when the clamp halves shown in Figures 9A and 9B are joined. In the united state, the curved sections are provided with the similar ribs in Figures 9A and 9B forming a passage channel for an elongate object, ie for example for the bundle of wires shown in Figure 8. Similar ridges at ribs 10 are arranged side by side in the pressure elements 2A and 2B. When the two clamp halves of Figures 9A and 9B are joined in the operative position, the rib-shaped projections extend to the passage channel to reduce the free diameter thereof. Rib-like shoulders 10 consist of a flexible material, such as rubber, rubber, silicone or the like, and are advantageously formed of a layer (not shown) that is connected to the inner surface of the passage channel. Each of the clamp halves shown in Figures 9A and 9B is provided with flange elements 6 which are opposite one another in pairs. These flange elements extend in the dividing plane along the clamp that is divided. Each of the flange elements 6 is provided with clamping measurement by boring holes with the help of which the clamp halves shown in Figures 9A and 9B can be fixed in the operative position. It is urgent to say that in the operative position a bunch of wires is arranged in the passage channel formed by the two pressure elements 2A and 2B and that pressure is exerted on the section of the wire bundle which is arranged in said passage channel, to know by exerting pressure on the flange members 6. Preferably, the rib-like shoulders have a height of about 3 mm and are preferably separated from each other by about 2 to 5 mm. Advantageously, the shoulders 10 have a wedge-shaped cross-sectional design, said shoulders being secured with their wide ends to the associated pressure elements 2a and 2b, respectively, and are oriented with their tips into the interior of the passageway formed by the two parts of the inventive clamp to slightly reduce the free diameter of said channel. These rib-like shoulders 10 have double function. First, they ensure that the wire bundle formed by the wires is retained in an anti-slip manner even in cases in which the diameter of the wire bundle becomes smaller as a result of the shrinking process over time and secondly , in the case of such shrinkage phenomena, the ridges ensure that the sealing effect achieved between the surface of the wire bundle and the inner circumference of the clamp is maintained by means of a "self-healing" procedure. The shrinking processes mentioned above can be caused when a sealing means used to fill the cavities between the adjacent wires of the wire bundle and to fill a space between the outer circumference of the wire bundle and the inner circumference of the clamp disappears in over time. Such sealing means contain, for example, butyl, or other adhesive sealants. Among the experts, so-called "adhesive tapes" are known which make use of the butyl adhesive and sealant effect, as described in DE 4441513A1 of the applicant. Each of Figures 10A and 10B are a plan view on the parts illustrated in Figures 9A and 9B in perspective. The end shown on the left side of the drawings and belonging to the pressure elements 2A, 2B with rib-like shoulders 10 is followed by a connecting section consisting of the halves 4A and 4B. This connection section is divided in the same plane as the pressure section comprising the pressure elements 2A, 2B adjacent to said connection section. The connection section is funnel-shaped and a passage opening extends in a funnel-shaped manner. This passage opening is aligned with the passage channel of the pressure section and, in the transitional area extending from the pressure section to the connection section, the passage opening of the connection section has the same internal diameter than the passage channel of the pressure member. This passage opening expands progressively to the left side in the drawing.

As already described, the connection section elements 4A, 4B of all the embodiments described may have reinforcing portions, such as the reinforcing element 25, within their interiors. This reinforcing element 25 can be made integrally with the pressing elements 2A, 2B and a predetermined degree can be extended to the connecting element. The area of the funnel elements 4A, 4B which is close to the pressure sections 2A, 2B is enhanced with the reinforcing element 25, in particular in the narrowest funnel portion that can be seen in the drawing. In this preferred embodiment, the outer edge portion of the funnel-shaped connecting section elements 4A, 4B has a lower strength than the remaining clamp. The outer part of this flexible elc edge portion of the funnel-shaped connection section has formed thereon a locking edge 12 which actuates together with a sealing lip 14 to provide a sealing means. When the clamp according to the invention is inserted into an opening of a partition wall, this sealing means sealingly surrounds an edge (not shown) of the wall with the elements 12 and 14. The clamp according to the invention preferably comprises in part of polyamide (PA). It is only the flexible elc edge portion with the sealing lip 14 and the locking edge 12 which consists of a softer material, such as EPDM / TPE, and extends around the reinforcing element (refer to Figure 3). As already mentioned, the rib-like shoulders 10 which are provided in the passage channel formed by the two pressure elements 2A, 2B in their joined operative position consist of a flexible elc material, such as rubber or silicone. The divided clamp according to the invention is preferably used as follows: First, a bundle of wires such as the bundle of wires shown in Figure 8 is inserted into one of the two clamp halves. When it is desired to make the bundle of water-tight wires in the longitudinal direction in the area of the clamp, adequate quantities of butyl or other suitable sealant material must be provided to seal all the spaces between the adjacent wires of the wire bundle with seal. but also all those existing between the outer circumference of the wire bundle and the inner circumference and the clamp in the area of the pressure elements 2A, 2B. In such a case, the opening of the passage is undersized in the area of the pressure elements in relation to the bundle of wires (bundle of wires) comprising the sealing material. When the divided clamp is closed around the bundle of wires and the flange elements 6 move towards one another, a uniform pressure is exerted on the part of the bundle of wires that is located inside the passageway by means of which it is pressed with sealing the sealing material to all the hollow and intermediate spaces and thus the wire bundle is made watertight in the longitudinal direction. If longitudinal waterproofing is not attempted in the above-described sense, butyl or other sealing materials can be dispensed with. If the outer diameter of a bundle of wires is too small to ensure the required sub-dimensioning with respect to the inner diameter of the passage channel (in the area of the pressure elements 2A, 2B), the bundle of wires will be provided in the desired area with the liner 50 shown in Figure 8. This section 50, which has an enlarged diameter, is then introduced into one of the halves of the split clamp, whereupon the other half of the clamp is connected to the first half, surrounding with it the bundle of wires. In this way, the clamp according to the invention makes it possible to conduct a bundle of wires through a wall opening with the outer edge of a clamp surrounding the wall opening with sealing., if desired, the bundle of water-tight cables should be oriented in the longitudinal direction in the area of the clamp. The annular ribs 10 which are provided in the passage channel area of the pressure member 2A, 2B ensure a slide-proof retention of the bundle of wires of the clamp (if sealing materials are not provided between the wires of the wire bundle and / o between the outer circumference of the wire bundle and the clamp) and ensure a self-healing effect of the case of sections of the bundle of wires that are made watertight in the longitudinal direction, if the outer diameter of the bundle of wires should exclude, as consequence of phenomena of shrinkage of the sealing compound. In such a case, the elastic-like and flexible rib-like shoulders 10 compensate for the shrinkage, with the result that the water tightness in the longitudinal direction is ensured despite the shrinkage. Figure 11B shows a bundle of flat ribbon cables that are covered by a liner 50 'which, in regard to its purpose, is identical to the liner 50 shown in Figures 8A and 8B. While the bundle of cables shown in Figures 8A and 8B has a substantially circular cross section, the bundle of flat ribbon cables shown in Figure 11B has a substantially square or rectangular cross section. The part of an inventive bracket as shown in Figure 11A has a through channel having a square or rectangular design and is therefore adapted to the cross-sectional design with a bundle of wires as shown in Figure 11B. Needless to say, such a passageway with a square or rectangular design does not necessarily comprise the rib-like shoulders 10 as shown, but may have a smooth surface, as shown for example in Figures 1, 3, 5A and 5B. In its preferred embodiment, the clamp according to FIG. 11A is provided in the funnel-shaped connection element with the reinforcement element described with reference to FIG. 3, which preferably comprises polyamide. The outer member of this funnel-shaped connection element consists, as described with reference to FIG. 3, of a more flexible material, preferably EPDM. Figures 9 to 12 show that the clamp on the dividing surfaces of the funnel-shaped connecting section 4 has a tongue and groove system by means of which the halves of the connecting funnel can be fluid-tightly interconnected. To be more specific, these figures show a tongue of shoulder 16 and a receiving groove 18 on the surfaces on the illustrated dividing surfaces. A tongue and groove system is preferred on the dividing surfaces of the connecting sections in all embodiments of the inventive bracket. The divider surfaces, including grooves and tabs, consist of soft plastic material, such as EPDM / TPE. In the case of the connection portions does not consist entirely of such plastic material, the dividing surfaces, including grooves and tabs, are coated with at least one flexible plastic material (EPDM). As an alternative to the tongue and groove system described above, full-area adhesive joints can be used for the water-tight connection of the dividing surfaces of the connecting sections. The provision of two dividing surfaces with a sealing compound can also be used successfully. The clamping flanges 6 can also be coated with a rubber-like material, such as EPDM / TPE, to obtain a fluid-tight design. The design of the outer circumference of the funnel-shaped connecting section 4 with the locking edge 12 and the sealing lip 14, as discussed in the embodiments described above of the inventive clamp, can be replaced by any other suitable design. For example, Figure 13 shows a clamp that is divided according to the invention and with the funnel-shaped connecting section 4 to a body sheet 19 in the area of its circumference. To this termination, appropriate screw means are provided. in the circumferential area of the connection 4. Figure 13 shows a sealing ring which is integrated into the J * funnel shape by connecting section 4. All the known drawing modes, push or push clamps can be produced as a split type, provided that the design is appropriate for it. The funnel portion can have the desired shape. Figure 14 shows the outer circumferential design connecting the external thread 22 which is formed on the lower circumference outside of the funnel-shaped connection section 4. The internal cord that is provided on a divisible ring 24 can be screwed into this external thread 22 to retain the body sheet 19 disposed therebetween. As can also be inferred from Figure 14, a sealing ring 20 is provided which is integrated into the connection section 4 in the form of funnel to ensure the watertight connection of the clamp to the wall. Figures 15 to 17B show a clamp which is divided according to the invention and which differs from the modalities previously described, in essence by the feature that the connecting section 4 is not funnel shaped. In the embodiment shown in FIGS. 15 to 17B, the connection section 4 also follows the pressure section in the longitudinal direction, ie axially.

The embodiment of the split clamp of the invention as shown in Figure 15 differs from the embodiment of the split clamp of the invention as shown in Figure 1A mainly by the design of the P connection section that in both modes consists of a top 4b and a lower part 4a. Although this is not shown in Figure 15, the connecting section elements 4a, 4b of the embodiment according to Figures 15 to 17B consist of hybrid material, namely a stiffening material that serves as a "skeleton", which corresponds to the reinforcement material in Figure 3, and a non-rigid elastic material, such as EPDM / TPE, which surrounds said stiffening material. As the embodiments of the inventive clamp that are provided with the funnel-shaped connecting section, the connecting sections 4a and 4b of the embodiment shown in FIG. 15 are provided on their divider surfaces with a tongue and groove system 16, 18. As a consequence of the structure described above that consists of a rigid inner material, preferably polyamide, and a softer outer material (EPDM / TPE), in combination with the tongue system I and slot described above, it has been possible to ensure dimensional stability and airtightness in the area of the dividing planes. The absence of dimensional stability in the area of the divider surfaces would result in the formation of small passage openings between the dividing surfaces with the action of external forces, which would result in leakage.

In contrast to the modalities described above, the embodiment according to Figures 15 to 17B is not designed to be pulled with seal to a board wall, but is designed to be slid with seal towards the wall. Such a wall is designated schematically in Figure 15 with the reference number 28 (lower part) and the reference number 28 '(upper part). As can be inferred from FIG. 15, the lower portion 4a of the connecting section includes a profiled portion 26 which positively drives together with a shaped portion formed in the lower wall 28 to form a seal. The upper half 4b of the connection section is provided with sealing strips 34 whose design acts together in a positive manner with a corresponding design at the lower edge of the upper wall section 28 'to form a seal. In the operative position, the connecting sections 4a and 4b are connected with seal to the wall 28, 28 ', so that the wire handling illustrated in Figure 15 passes through sealing through said wall 28, 28'. As already described with reference to the preceding embodiments, a pressure element 2a (lower part) and 2b (upper part), respectively, axially (longitudinally) follows the connection selection elements 4a, 4b. As described with reference to the preceding embodiments, the pressure elements consist, at least in the area of the connection flange 6, of a sufficiently rigid material, such as polyamide (PA). Advantageously, the pressure elements and the stiffened portions for the connection section elements 4a, 4b are integrally made in all the embodiments of the inventive bracket. Figures 16a and 16b show several perspective views of an upper half shell of Figure 15, each with the pressing element 2b and the connecting section element 4b and with the sealing strips 34, as described with reference to the Figure 15. Figure 16B shows that the pressure element section 2b consisting of a rigid material is provided with an inner liner similar to rubber in which transverse ribs 10 are formed, as described and shown above with reference to the figures 9 to 11a and 12. In Figures 17A and 17B, the lower half shell according to Figure 17 is shown in several perspective views. As can be inferred from Figure 17B, the lower half-shell pressure section is also provided with an inner rubber-like liner which may comprise the shoulder ribs 10 already described. It should be noted that the tongue and groove means provided on the dividing surfaces of the connecting section elements 4a and 4b are not shown in FIGS. 16 and 17. The screws 37 can be screwed through the bored holes formed in the FIGS. fastening flanges 6 to the screw receiving means 39, which are shown in Figures 15 and 17, are provided in Figure 15 for attaching the upper helmet half and the lower helmet half.

The bundle of wires shown in Figure 15 is provided with a liner 50 that is already described above with reference to Figure 8A. Such liner 50 is conveniently provided with the diameter of the bundle of wires not having the necessary oversize with respect to the diameter of the passage channel 5. It can be secured with the help of the lining 5C that the wire bundle is held with a pressure adjustment between the pressure elements 2a and 2b when interconnecting in their operative position the two half shells forming clamp according to the invention. In the embodiment according to Figures 15 to 17, the connecting section 4 may consist predominantly of a preferably rigid material and it is possible only that the profiled portion, ie the lamellae shown in the drawing, is coated with a material softer or more flexible plastic to ensure the desired design of dimensionally stable seal in the area of the divider surfaces. As an alternative, the edge portion of the passage can also be provided with a flexible elastic lobe, whereby the connecting section 4, including the shaped portion (contour) is made of a preferably rigid plastic material. In some cases, it may be advantageous, when the free ends of the pressure sections of all the modalities described above, that is to say the end opposite the connection section, have mounted on them support or coupling elements, such as lower cuts. , with the aid of which the collapsible coupling members of conventional corrugated protective tubes can be coupled with the clamp of the invention. Such coupling elements are designated, for example, in figures 1, 2 and 3 with the reference numerals 30. Figure 18 shows only one pressing element 2a of a half shell of the inventive bracket, the pressure element being combinable with each one of the connection section elements 4a described above to form a complete (lower) helmet means. In the pressing member shown in Fig. 18, the curved section 55 of the passage channel that is formed between the two spring elements 8 consists of a rubber-like, flexible or semi-flexible material, such as EPDM / TPE. In the illustrated embodiment, this rubber-like material is held in the opposite areas designated with 56, with the rubber-like material extending between these areas in the manner of a hammock, as illustrated by the drawn curvature. The parts in the illustrated pressure element 2a that differ from the section 55 of the "hammock" type consist of a rigid material, such as polyamide (PA). The clamp according to the invention can be a pressure element with a flexible or semi-flexible section 55 in each of its two half shells or only in one of its half shells. The design of at least one of the pressure elements with section 55 of the "hammock" type, as shown in figure 18, makes it possible to adapt the diameter of the passage channel to the diameter of the bundle of wires received in the channel in passing, in particular with the handling of wires has certain dimension. As already described with reference to FIG. 8, an over dimension of the diameter of the bundle of wires in relation to the diameter of the passage channel must always be oriented to exert the desired pressure on the bundle of wires. received in the pass channel. As already described, all the embodiments of the invention have in common that in cases where water tightness in the longitudinal direction is not necessary within the wire bundle, the desired oversize can be achieved with the help of the liners 50. (figure 8A) and 50 '10 (figure 11 B) or the fillers described in DE 19640 816 A1. In contrast, when water tightness is required in the longitudinal direction, an over dimension will be obtained almost automatically through the measurement of a sealing compound, such as butyl, which increases the circumference of the wire bundle is incorporated in compliance among the 15 wires of the wire bundle. In the embodiment according to figure 18, the section of type I of "hammock" exerts a constant pressure on the bundle of wires provided in the channel of the passage, by means of which it is ensured that the pressure exerted on the bundle of wires is maintained. In cases where the sealant compound 20 could shrink in this manner, the rubbery, flexible or semi-flexible material of section 55 has a continuous effect on the sealing compound, resulting in a "self-healing effect" in case which disappears the sealing compound. The embodiments according to figures 9 to 14 and 16B to 17B differ from the embodiment of figure 18 by the characteristic that in the aforementioned, which consists of a solid (rigid) material, such as polyamide, is provided only an inner liner of a flexible material, such as rubber, rubber, silicone, or the like, of which rib-like shoulders 10 are illustrated. For clarity, it should be noted that in all embodiments of the inventive clamp illustrated and described in this application, "passageway" always means the tubular space that is provided to receive a bundle of wires and is obtained between the two pressure elements 2a, 2b which are interconnected as desired. Furthermore, for clarity it should be noted that within the scope of the present application, "middle helmet" means a structure comprising respectively a pressure element and a connecting section element, the structure being adapted to be joined with a second half helmet for forming a clamp that is divided according to the invention. To connect the two halves, screw connections (Figures 1 to 3 and 15 to 17), lock connections (Figures 5 to 7) and the like have been described above. Figure 19 illustrates a design that is advantageous with respect to the shrinkage described above of a sealing compound that is provided in the bundle of wires. This figure shows schematically the right hand parts of the upper half helmet (4b, 2b) and the lower half helmet (4e, 2a) of the arrangement illustrated in figure 15. For example, the sealing strips 34 and the tabs 16 are also shown. Figure 19, the reference number 60 designates a spring fastener which serves to securely interconnect the upper half helmet and the lower half helmet in the operative position. When in the operative position, the fastening flanges 6 of the upper half helmet and the lower half helmet are placed one above the other, the spring fastener 60 fixed around the fastening flanges placed one on top of the other, with the securing strip of the fastener of spring 60 acting on the upper separating flange and the other separating strip of the spring fastener acting on the lower part of the lower separating flange. In the illustrated embodiment, longitudinal grooves 61, of which Figure 19 uses such groove 61 in the clamping flange, are provided in clamping flanges. If the diameter of the wire bundle is shrunk during the service life of an inventive clamp, the advantageous pressure exerted on the wire bundle cross-section is maintained and as a consequence of the spring force of the spring clamp 60 and the self-locking effect. desired is secured or at least supported in this way.
