Description

The invention relates to a cable entry device for configuring a cable entry arrangement and a strain relief device for a cable entry device. The invention further relates to a method for configuring a cable bushing arrangement.

Cable bushing arrangements are used in particular to carry out an electrical line, in particular a cable, through a wall opening, for example a housing wall opening or a control cabinet wall opening. Such cable bushing arrangements can be used in particular to combine and hold a number of electrical lines or other strands.

Cable bushing arrangements of the type mentioned at the outset can prevent the electrical lines from being damaged by relative movements during operation at the edges of the wall opening. In addition, cable entry arrangements can have additional functions. In particular, cable entry arrangements often have a sealing function. Here, a line is sealed within the cable bushing arrangement against liquid passage and possibly gas passage. Furthermore, a function can be provided which provides for the grounding of a shielded line via the cable bushing arrangement, in that an electrical contact is made from a shielding braid of a line to the wall in which the wall opening is formed, through the cable bushing arrangement.

Cable entry arrangements are used in numerous applications in large numbers and are therefore subject to high price pressure as mass products, from which the endeavor results in a simple and therefore inexpensive production method. In addition to this requirement for production that is as simple and therefore inexpensive as possible, it is also desirable for the fitter to be able to install cable lead-through arrangements as quickly and correctly as possible. This means that neither an incorrect assembly of the cable entry arrangement or incorrect alignment / attachment / tightening of individual parts of the cable entry arrangement nor a time-consuming selection of the correct individual parts is desirable.

Regardless of the fact that savings are indicated in the manufacturing costs and a simpler assembly is desired, the claim is made on a cable bushing arrangement that it reliably clamps the cable guided through the wall opening and thereby relieves strain. In order to ensure reliable strain relief, cable bushing arrangements must be adapted to the cables to be clamped, in particular their diameters. It must be taken into account here that often several cables, for example also with different diameters, have to be produced and kept available with a single cable bushing arrangement. The manufacturing costs are kept high by manufacturing a wide variety of cable bushing arrangements. Furthermore, the assembly costs are increased by time-consuming selection of a suitable cable bushing arrangement from a large stockpile. Large stocks also have a negative impact on manufacturing costs and assembly costs.

In the sense of low stockpiling, it is desirable that cable bushing arrangements are available which enable the receptacle for lines with different diameters and / or for a different number of lines. This striving for a low stock level usually stands in the way of striving for a high level of assembly functionality, particularly with regard to reliable strain relief.

Out DE 10 2016 223 425 A1 For example, a cable holder with an elongated strip with partition walls standing thereon, each of which forms a space between them, with grommets arranged in some or all of the spaces, each having a bore for the passage of a cable and which can be opened. The grommets are made of an elastic material to accommodate cables. Cable holders that can be fitted with grommets are also from the publications DE 10 2017 209 368 A1 , DE 10 2017 220 665 A1 , DE 10 2005 037 561 B4 , DE 299 24 314 U1 , EP 2 746 634A1 , EP 1 376 795 B1 , DE 102 25 046 B4 , EP 1 792 377 B1 , DE 10 2011 011 868 A1 , DE 10 2009 060 988 B3 and EP 1 236 256 B1 known. Such cable holders known in the prior art can often be fitted with different grommets and are used to carry out cable runs through a wall without chafing.

The publication also discloses DE 103 49 996 B4 a grommet for passing a line with a sleeve for enclosing the line, a base body enclosing the sleeve, the base body and the sleeve being formed in one piece with one another and a cavity being located between the base body and the sleeve. The spout has a slot for opening to receive the line, the elasticity of the material of the spout being smaller in the area of the slot than outside this area. At this The type of grommet is also aimed at the function of a bushing of an electrical cable that is secured against the insulation being chafed, while at the same time offering the possibility of simplified installation.

Such grommets known in the prior art are suitable for receiving a line cable and holding it in the cable bushing arrangement. The cable is protected from mechanical damage by preventing it from being chafed at the edge of the wall lead-through opening by the grommet and by mechanical movement overload within the grommet and through the grommet. However, this type of grommet is not suitable for certain requirements in which such grommets are also intended to protect an internal connection point of the cable line from mechanical stress.

The invention is therefore based on the object of providing a screwed cable gland which increases the functionality in terms of assembly technology and thereby enables mechanical protection for a line connection of the line cable being carried out.

According to a first aspect of the present invention, this object is achieved by a cable lead-through device for configuring at least one first cable lead-through arrangement for leading one or more cables through a wall opening and one different from the first second cable lead-through arrangement for leading several cables through the wall opening, comprising: a frame body , which frames an inner receiving section, a first strain relief insert which is designed to be received in the receiving section of the frame body, the first strain relief insert having an outer circumference, at least one cable passage opening and in each case one insertion slot connecting each cable passage opening to the outer circumference, a second strain relief insert , which is designed to in the receiving portion of the frame body instead of the first strain relief insert or next to the first strain relief insert The second strain relief insert has an outer circumference, at least two cable passage openings and in each case an insertion slot connecting each cable passage opening to the outer circumference, the first strain relief insert and the second strain relief insert each having strain relief elements which delimit a cable passage opening and are movable between a cable pull position and a strain relief position , and which limit a first passage cross-section of the cable passage opening in the cable pull-through position, which allows the passage of a cable through the cable passage opening in at least one pull-through direction, and limit a second passage cross-section of the cable passage opening in the strain-relief position, which allow the passage of a cable through the cable passage opening in at least one pull-through direction locks.

The invention is based, inter alia, on the knowledge that cable bushing arrangements as a whole, preferably in a preassembled state, are placed on the market in order to simplify the assembly of the cable gland itself. However, it is necessary to provide a wide variety of cable routing arrangements for holding and relieving strain on a different number of cables and of cables with different cable diameters. This requires a larger stock of individual cable entry arrangements.

The inventors have recognized that the solutions known in the prior art hold cables by means of a frictional resistance between an outer cable jacket and a grommet made of elastic material. According to the inventors' knowledge, this frictional resistance can make it difficult to move the grommet and the cable against one another, but it cannot lead to a frictional connection. Therefore, such a grommet cannot reliably block the passage of a cable in at least one direction of passage. Known solutions therefore do not guarantee reliable strain relief for the cables. Furthermore, the invention is based on the knowledge that a passage opening of the grommets for receiving the cables must be matched exactly to the respective cable diameter in order to be able to hold the cable.

In the solution described here, therefore, a cable feed-through device is provided, which comprises individual parts as a kind of kit, in order to enable configuration of different cable feed-through arrangements. The cable bushing device in this case comprises a frame body, a first strain relief insert and a second strain relief insert, preferably in an unassembled state, and accordingly describes a storage state of different cable bushing arrangements. By arranging the first strain relief insert and / or the second strain relief insert in the frame body, a cable bushing arrangement can be provided according to the invention. The frame body is designed to receive and thereby hold the first strain relief insert and / or the second strain relief insert.

The combination of the frame body with the first strain relief insert and / or the According to the invention, the second strain relief insert enables a configuration of at least the first cable entry arrangement and the second cable entry arrangement. The first cable bushing arrangement can be different from the second cable bushing arrangement.

According to the invention, the first strain relief insert differs from the second strain relief insert in that the first strain relief insert has at least one cable passage opening for the passage of a cable and the second strain relief insert has at least two cable passage openings each for the passage of a cable. Accordingly, the first strain relief insert can accommodate exactly one cable and the second strain relief insert can hold at least two, that is to say several, cables. Therefore, cable bushing arrangements with a different number of cable passage openings can preferably be configured to accommodate a different number of cables.

The specification "several" can preferably describe "more than a single" cable. Accordingly, this specification can preferably also include two and three cables.

A frame body can preferably be understood to mean a hollow body which has the receiving section. The receiving section can preferably be formed by the cavity of the frame body.

A frame body can preferably comprise at least two, preferably four, frame parts assigned to one another, which can preferably define an intermediate space. Here, the receiving section can preferably be formed by the intermediate space.

With the strain relief insert, the cable can be clamped inside the frame body and thereby relieved of strain. For this purpose, the first strain relief insert and the second strain relief insert each have strain relief elements, which each delimit a cable passage opening. The passage cross section of the cable passage opening can be limited by moving the strain relief elements from a cable passage position into a strain relief position such that the passage of a cable through the cable passage opening is blocked in at least one direction of passage. This configuration enables the passage of a cable through the cable passage opening in the cable passage position and the cable in the strain relief position can be clamped in the cable passage opening in such a way that it is strain relieved in at least one direction of passage. As a result, cables can preferably be fixed axially in their longitudinal direction in at least this one pulling direction.

A movement of the cable in the pulling direction can preferably describe a pulling of the cable inside the cable passage opening in the longitudinal direction of the cable. This allows, for example, positioning of the strain relief element and / or the frame body.

The strain relief insert can preferably be designed such that when a cable is inserted therein and is moved in a first direction, the cable pulling direction, it is moved into the cable pulling position, for example by elastic deformation of the strain relief insert. The strain relief insert can furthermore be designed such that, when a cable is inserted therein and is moved in a second direction, the strain relief direction that is opposite to the first direction, it is moved into the strain relief position, for example by elastic deformation of the strain relief insert . Thus, a one-sided locking effect can be achieved by elastic deformation of the strain relief insert.

As an alternative or in addition, a pull-through can also be blocked in both possible pull-through directions in the strain relief position in order to be able to position the cable in the strain relief insert in a stationary manner.

To block the passage in this at least one pulling direction and thus to achieve the strain relief, the strain relief inserts each have strain relief elements which are arranged and designed to limit the passage cross section of the cable passage opening. The first strain relief insert here has strain relief elements which are arranged and designed to form at least one cable passage opening and in each case to limit the passage cross section of the at least one cable passage opening. The second strain relief insert has strain relief elements which are arranged and designed to form at least two cable passage openings and in each case to limit the passage cross section of the at least two cable passage openings.

A cable passage opening can preferably be understood to mean an opening with the passage cross section which is designed to receive a cable. According to the invention, the cable passage opening is connected to the outer circumference of the strain relief element via the insertion slot. The outer circumference can preferably be one Describe the area outside an outside of the strain relief element.

The insertion slot can preferably be understood as a narrow, in particular elongated, opening which is designed to lead a cable through the insertion slot and to insert it into the cable passage opening.

The cable can be easily inserted and positioned in the strain relief insert through the insertion slot. This enables particularly simple and quick installation.

The corresponding strain relief insert can preferably be arranged in the frame body after the cable has been inserted into the cable passage opening. Alternatively, the corresponding strain relief insert can first be arranged in the frame body, in particular on a part of the frame body, and then the cable can be inserted into the cable passage opening.

A cable bushing arrangement can preferably be understood to mean an arrangement comprising the frame body and at least one strain relief insert, which is designed to be preferably arranged on or in the wall opening.

In particular, the cable bushing arrangement can also be combined with existing cable bushings, such as, for example, flange plates and / or screwed cable glands, in order to supplement them with the cable bushing arrangement. In this case, the cable entry arrangement can preferably be attached to the existing cable entry arrangement. This means that already installed cable bushings can be upgraded in order to achieve reliable strain relief.

Another advantage of this cable lead-through device is the modularity, which enables cable lead-through arrangements to be configured as required, in particular with regard to the cables to be clamped.

The strain relief elements can preferably be arranged on the strain relief inserts. In particular, the strain relief elements can be moved individually from the cable pull-through position into the strain relief position. Furthermore, the strain relief elements can be fastened to a strain relief insert in such a way that they can be moved from the cable pulling position into the strain relief position even by moving the strain relief insert.

Due to the movement of the strain relief elements from the cable pull-through position into the strain-relief position, cables with different cable diameters can preferably be clamped by means of the same strain-relief elements and thereby reliably strain-relieved. Due to the movable strain relief elements, the strain relief inserts can be adapted to the cable diameter.

It is also advantageous that due to the modularity and the usability of individual strain relief inserts for a large number of different cable diameters, the cable bushing arrangements can be assembled in a simple manner by personnel on site.

In a preferred development of the cable feed-through device, the first passage cross section of the cable passage opening in the cable passage position is larger than the second passage cross section of the cable passage opening in the strain relief position.

This can preferably ensure that the cable can be passed through the cable passage opening in the cable passage position in at least one direction of passage and that the passage in at least one direction of passage can be blocked in the strain relief position. Due to the reduced passage cross section in the strain relief position, which is limited by the strain relief elements, a clamping effect can be generated on the cable by means of the strain relief elements. By moving the strain relief elements from the cable passage opening into the strain relief position, the cable can thus be clamped in the cable passage opening and thereby strain relieved.

It is further preferred that the strain relief elements are designed to be movable, in particular axially-radially movable, from a prestressing position into the cable pull-through position, the strain-relief elements limiting a third passage cross-section of the cable passage opening in the prestressing position, which is smaller than the first passage cross-section of the cable passage opening in the cable pull-through position and the second passage cross section of the cable passage opening in the strain relief position. In this case, the strain relief elements can preferably be moved axially-radially outward by introducing the cable into the cable passage opening, so that the passage cross section is enlarged. As a result of this axial-radial movement, the strain relief elements can preferably be moved from a rest position, so that they bring about a restoring force on the cable sheath in the cable pull-through position and clamp the cable in the strain relief position.

In particular, it is preferred that the strain relief elements in the cable pull-through position and / or in the pretensioning position within the cable passage opening are spaced from or rest on the cable jacket of the cable. In the strain relief position, the strain relief elements can preferably be pressed onto the cable sheath, in particular pressed in, and thereby clamp the cable. For example, the cable can be inserted into the cable passage opening and can be passed in a pulling direction in order to bring the cable or the strain relief element into position. Applying a force against this pull-through direction can preferably cause the strain relief elements to press against the cable jacket, preferably press into the cable jacket, and thereby clamp and relieve the cable.

It is particularly preferred that the strain relief insert has an outer edge and the strain relief elements extend from the outer edge in the direction of a longitudinal axis, the strain relief elements being designed to be axially and radially movable from the cable pulling position into the strain relief position, and the outer edge being the insertion slot having.

The longitudinal axis can preferably be understood to mean an axis which extends essentially through a center point of the cable passage opening, in particular of the strain relief insert. The longitudinal axis can preferably be substantially parallel to the outer edge.

The strain relief elements can preferably be designed as a type of web. In the prestressed position, that is to say in a relaxed state, the strain relief elements can extend essentially radially from the edge in the direction of the longitudinal axis. Alternatively, the strain relief elements can extend axially-radially from the edge in the direction of the longitudinal axis. Here, the strain relief elements can be moved radially outward in the axial direction, preferably from the pretension position into the cable pull-through position, by inserting a cable. Furthermore, the strain relief elements can be moved radially inwards in the axial direction, in particular by applying a force against the at least one pulling direction from the cable pulling position into the strain relief position. The clamping effect can preferably be brought about by a diameter of the cable itself.

If reference is made to outward and / or inward, these directions refer to the frame body, in particular the cavity or intermediate space formed by the frame body, or to the outer edge of the strain relief insert, in particular the cavity formed by the outer edge. Inward is therefore to be understood as a direction starting from the frame body or the outer edge into the corresponding cavity or intermediate space, that is to say preferably in the direction of the longitudinal axis. Accordingly, an outward direction is to be understood as starting from the frame body or the outer edge outwards, that is to say away from the longitudinal axis.

The cable bushing arrangement, in particular the frame body and / or the first strain relief insert and / or the second strain relief insert and / or the strain relief elements, can preferably comprise a hard plastic or be formed from a hard plastic. In particular, the hard plastic can be polypropylene and / or polyamide and / or polycarbonate and / or polyvinyl chloride and / or polyethylene and / or another thermoplastic. By designing the strain relief elements from a hard plastic, a reliable clamping and strain relief of the cable can be guaranteed within the cable passage opening.

In particular, it is preferred that boundary webs are arranged on the outer edge, which are designed to limit a maximum second passage cross section. This configuration limits the maximum passage cross section and thereby also limits a maximum, clampable cable diameter in order to avoid cables having such a large cable diameter that cannot be reliably clamped being inserted and / or in particular also leading to material fatigue of the strain relief elements and / or the outer edge.

Preferably, at least one boundary web can be arranged on the outer edge, which is designed to limit a maximum second passage cross section.

A boundary web can preferably be understood to mean an element which is arranged within the outer edge, preferably on an inner circumference of the outer edge, and thereby reduces an interior space of this outer edge, which is defined by the outer edge and essentially corresponds to the passage cross section. Here, the delimiting web can preferably have straight and / or curved and / or round sections.

It is further preferred that at least two strain relief elements are connected to one another at free ends via a connecting element, wherein the connecting element is preferably designed to be elastic and / or wherein the connecting element preferably has a predetermined breaking point. Providing the at least two strain relief elements with a connecting element at the free ends can ensure particularly simple assembly. In addition, it can be avoided that a cable is positioned incorrectly within the cable passage opening and is therefore not relieved of strain. Due to the elastic configuration and / or the configuration with a predetermined breaking point, it can be ensured that the strain relief elements can be moved into the strain relief position in order to clamp the cable.

The connecting element can preferably have straight and / or curved and / or round sections.

According to one embodiment variant, it is preferred if the first strain relief insert and the second strain relief insert are designed to be arranged next to one another and to move the strain relief elements between the cable pull-through position and the strain relief position by twisting each other, preferably in the strain relief position the strain relief elements of the first strain relief insert blocking each cable passage opening with the insertion slot of the second strain relief insert connecting the outer circumference, and preferably in the strain relief position the strain relief elements of the second strain relief insert blocking the insertion slot of the first strain relief insert connecting each cable passage opening with the outer circumference. The first and the second strain relief insert can preferably be identical. The two identical strain relief inserts can be connected to one another, for example, in a mirrored arrangement.

According to this embodiment variant, the strain relief elements are attached to a strain relief insert in such a way that they can be moved from the cable pulling position into the strain relief position even by moving the strain relief insert.

Preferably, the strain relief inserts with the strain relief elements can each have a flat extension and be designed to be preferably stacked on top of one another. The strain relief inserts can preferably each be arranged in a frame part which is part of the frame body.

The frame body may preferably comprise a first frame part and a second frame part, the first frame part and / or the second frame part each being connected to a strain relief insert. The first frame part can preferably be connected to the first strain relief insert and in particular have a holding means, which is preferably designed to receive the second strain relief insert and fix it in one position. The holding means can preferably be designed as a groove on an inner circumference of the first frame part. The holding means can particularly preferably have latching means in order to enable the second strain relief insert to be fixed in one position, preferably in the strain relief position and / or in the cable pulling position.

The second frame part can preferably be connected to the second strain relief insert and in particular have a holding means, which is preferably designed to receive the first strain relief insert and to fix it in one position. The holding means can preferably be designed as a groove on an inner circumference of the second frame part. The holding means can particularly preferably have latching means in order to enable the first strain relief insert to be fixed in a position, preferably in the strain relief position and / or in the cable pulling position.

In particular, the strain relief inserts arranged in the frame parts can first be put together in such a way that the cable passage openings and insertion slots of the strain relief inserts are essentially flush with one another. The assembled state can preferably describe the cable pulling position. In a next step, the cables can preferably be introduced into the cable passage openings and the strain relief inserts rotated relative to one another in such a way that the first strain relief elements block the insertion slots of the second strain relief insert and the second strain relief inserts block the insertion slots of the first strain relief insert. As a result, the cable can be held in the cable bushing arrangement, preferably without a clamping effect being achieved. In this position, which is preferably also to be understood as a cable pull-through position, the cable bushing arrangement can simply be brought into the correct position. Only after positioning can the strain relief inserts then preferably be rotated further against one another in order to achieve the strain relief.

According to a further preferred development, it is provided that the frame body has a holding means which is designed to hold the first strain relief insert and / or the second strain relief insert captively. This configuration allows the first and / or the second Strain relief insert introduced into the frame body and fastened to the frame body by means of the holding means. Accordingly, the holding means is used to fasten the first and / or second strain relief insert in the frame body.

Preferably, the individual strain relief inserts can also have holding means in order to enable a strain relief insert to be attached to a strain relief insert arranged next to it in the frame body.

In particular, it is preferred that the holding means is formed on an inner circumference of the frame body, a corresponding holding means being formed on the outer circumference of the strain relief insert, the holding means being designed to be brought into engagement with the corresponding holding means. This configuration enables particularly simple assembly, since the first strain relief insert and / or the second strain relief insert can preferably be assembled without tools and preferably can be fastened in the frame body without an additional holding means.

The holding means can preferably be designed as corresponding latching means. A simple and reliable fastening of the strain relief inserts in the frame body can be made possible by latching.

It is further preferred that the holding means of the frame body is designed as a groove, the corresponding holding means of the strain relief insert is formed as a projection, the projection being designed to be brought into engagement with the groove. This configuration enables a particularly simple and quick assembly, which ensures secure fastening of the strain relief inserts or the strain relief insert within the frame body and thereby enables reliable strain relief.

The projection can preferably be formed by an outer edge of the strain relief insert or a part of the outer edge.

According to a further preferred development, it is provided that the frame body comprises a first frame part and a second frame part, the first frame part and / or the second frame part in an open state having a receiving opening and being designed to accommodate the first strain relief insert and / or the to record the second strain relief insert, the first frame part and the second frame part being connected to one another in the closed state and captively holding the first strain relief insert and / or the second strain relief insert.

The two-part design of the frame body with a first frame part and a second frame part enables particularly simple assembly since the first strain relief insert and / or the second strain relief insert can be introduced into the frame body through the receiving opening in the open state.

The frame body can preferably comprise two outer webs and two central webs. In this case, for example, the first frame part can be configured in three parts and in particular be formed by two central webs and an outer web that connects the two central webs to one another. The second frame part can preferably be formed as an outer web. This configuration ensures a simplified manufacturing process.

It is further preferred that the first frame part and the second frame part are loosely assigned to one another in the open state or the first frame part and the second frame part are connected to one another via a joint section.

By connecting the first frame part and the second frame part via a joint section, these are also fastened to one another in the open state, so that none of the frame parts can be lost during assembly. This further simplifies assembly.

According to a preferred embodiment variant, the frame body can preferably have fastening means which are designed to lock the frame body in the wall opening. For example, the frame body can have perforations that are designed to accommodate in particular screws and / or rivets and / or pins and / or bolts and / or the like in order to fasten the frame body to the wall opening. The frame body can preferably also have a thread, in particular an external thread or an internal thread, which is designed to fasten the frame body to the wall opening.

According to a further preferred development, it is provided that the cable bushing arrangement comprises a base body with an internal cable channel, the base body being designed to be arranged in and / or at the wall opening and the base body having a fastening section which is designed to mount the To attach the frame body to the base body. In this case, the base body can preferably be arranged on one side of the wall opening and the cable bushing arrangement on another side of the wall opening.

The fastening section can preferably be designed to be mechanically coupled to the frame body. Accordingly, a fastening section can preferably be understood to mean an area which has locking means, preferably non-positive and / or positive locking means or is designed to receive, preferably anchor, positive and / or non-positive locking means. The locking means can preferably be designed as a thread, preferably an external thread and / or a locking means and / or a bushing for screws and / or pins and / or rivets and / or bolts and / or the like.

In particular, a corresponding locking means can be provided, which is formed on the frame body or can be arranged on it, in order to enable locking with the locking means of the fastening section of the base body. Such a fastening section enables the frame body to be fastened to the base body and thereby securely anchors the cable bushing arrangement or the base body in and / or to the wall opening.

The base body can preferably be designed as a connecting piece, the frame body preferably being designed to rotatably support the first strain relief insert and / or the second strain relief insert, or as a flange plate. In particular, the strain relief arrangement, preferably the frame body, can be adapted to the shape and / or the function of the base body.

For example, the sealing element with the strain relief insert can be accommodated in the frame body. The sealing element can preferably also have a cable passage opening and an insertion slot connecting the cable passage opening with an outer circumference. In particular, it is preferred if the sealing element and the strain relief insert are connected to one another, preferably integrally, wherein the insertion slots and the cable passage openings are essentially aligned with one another.

According to a further aspect of the invention, the above-mentioned object is achieved by a strain relief device for a cable feedthrough device, comprising a first strain relief insert with an outer circumference, at least one cable passage opening and in each case an insertion slot connecting each cable passage opening to the outer circumference, a second strain relief insert which takes place in a frame body of the first strain relief insert or next to the first strain relief insert, the second strain relief insert having an outer circumference, at least two cable passage openings and in each case an insertion slot connecting each cable passage opening to the outer circumference, the first strain relief insert and the second strain relief insert each having a strain relief element which delimits a cable passage opening a cable pull position and a strain relief position are movable, and in the cable passage position limit a first passage cross section of the cable passage opening, which permits the passage of a cable through the cable passage opening in at least one pulling direction, and in the strain relief position limit a second passage cross section of the cable passage opening which blocks the passage of a cable through the cable passage opening in at least one passage direction.

By providing such a strain relief device, different strain relief inserts can be stored and can be used as required. As a result, cable bushing arrangements can be supplemented and completed accordingly, in addition to allowing the cable to pass through the wall opening and also to provide reliable strain relief for the cable.

According to a further aspect of the present invention, the above-mentioned object is achieved by a strain relief device for a cable bushing device, comprising a first strain relief insert part with an outer circumference, at least one first cable passage opening and in each case one insertion slot connecting each first cable passage opening with the outer circumference, a second strain relief insert part with an outer circumference , at least one second cable passage opening and in each case one insertion slot connecting every second cable passage opening to the outer circumference, the second strain relief insert being arranged adjacent to and attachable to the first strain relief insert, the first strain relief insert and the second strain relief insert being designed to be arranged against one another and through a relative movement against each other the first and second cable passage openings from a cable passage tensile position, in which the first and second cable passage openings are arranged completely or partially in alignment with one another and limit a cable passage cross section, into a strain relief position in which the first and second cable passage openings are arranged partially in alignment with one another and limit a strain relief cross section that is smaller than the cable passage cross section move.

According to this aspect of the invention, the strain relief on one or more cables is brought about by a relative movement between two strain relief insert parts. Each of the two strain relief insert parts has one or more cable passage openings that are larger than a cable that is to be strain relieved. In the aligned or - depending on the excess of the openings - partially aligned position of the opening in one strain relief insert and the opening in the other strain relief insert, a cable can be passed through a sufficiently large cross-section of the two openings or inserted in the radial direction. A relative movement of the two strain relief insert parts to one another reduces the degree of overlap of the two openings and brings the two openings into an only partially aligned position with one another. In this partially aligned position with reduced coverage of the two openings, the cable is clamped through the edges of the two openings and is thus relieved of strain.

The two strain relief insert parts are particularly suitable for use in a frame of a strain relief device of the type described above.

According to this development, the two or one of the strain relief insert parts have a frame section which blocks the radial insertion slot into an opening in the strain relief position in which the cables are clamped, which openings overlap fully or partially. This prevents the cables from slipping out radially.

It is still further preferred if the first and the second strain relief insert are identical. This reduces the manufacturing costs due to identical parts and leads to a simple inventory. In particular, the identical strain relief insert parts can be mirrored to one another or mounted to the strain relief device rotated relative to one another by 180 °.
