Description

[0001] Support sleeve system, method for assembling a support sleeve system, method for assembling a cable gland, cable and cable gland

[0002] The invention relates to a support sleeve system, a method for assembling a support sleeve system, a method for assembling a cable gland, a cable with a support sleeve system and a cable gland.

[0003] Various designs for contacting cable armoring are known from the prior art. For example, CH 690 809 A5 discloses a connection element for shielded conductors with a conical clamping sleeve that is arranged beneath a cable armoring. When a terminal fitting is screwed together with a ring nut, the cable armoring is clamped between a ring element of the terminal fitting and the conical clamping sleeve.

[0004] A disadvantage of the contacts known from the prior art is that they are complex to install and cannot be used multiple times. For example, with the clamping sleeves known from the prior art, which can be arranged under the cable armor, the cable armor is usually damaged when the latter is clamped. If, for example, a cable gland is loosened again, the damaged cable armor cannot be re-contacted or the contact surface is disadvantageously reduced, for example if individual strands of the cable armor break during clamping. The clamping sleeves known from the prior art are also loseable. Especially during reassembly, the clamping sleeve can get lost when the gland is dismantled.

[0005] The object of the invention is therefore to provide an improved support sleeve system for use as a counterbearing and / or contact surface for electrically contacting a cable armoring. In particular, the object of the invention is to provide a support sleeve system that can be pre-assembled onto a cable. In particular, the object of the invention is to provide an improved method for assembling a support sleeve system, an improved method for assembling a cable gland, an improved cable with a support sleeve system, and an improved cable gland. Preferably, the object of the invention is to provide a support sleeve system that enables convenient assembly and disassembly, or multiple assembly, of an armored cable.

[0006] The object is achieved according to the invention by means of a support sleeve system for use as a counter bearing and / or contact surface for electrical contacting of a cable armoring, at least comprising a fixing means and a support means, wherein the support means can be arranged under the cable armoring and the fixing means for fixing the support means can be applied to at least one end section of the cable armoring.

[0007] Furthermore, the object is achieved according to the invention by means of a method for assembling an above-mentioned support sleeve system comprising the steps

[0008] Stripping a cable to expose a cable armouring, threading a fixing means of the support sleeve system and a support means of the support sleeve system onto the cable such that the support means is arranged at least partially under the cable armouring and the fixing means is arranged at least partially over an end section of the cable armouring, and

[0009] Force-locking and / or form-locking connection of the fixing device to the cable reinforcement.

[0010] Furthermore, the object is achieved according to the invention by means of a method for assembling a cable gland comprising the steps

[0011] Mounting a support sleeve system on a cable as mentioned above, threading a cable gland onto the cable in such a way that at least one contact element electrically contacts a cable armoring in the region of a support means of the support sleeve system and / or electrically contacts a fixing means of the support sleeve system.

[0012] Furthermore, the object is achieved according to the invention by means of a cable with an above-mentioned support sleeve system, wherein a support means of the support sleeve system is arranged at least partially under a stripped cable armoring of the cable and wherein an end section of the cable armoring is arranged in a fixing means of the support sleeve system and fixed by means of the fixing means.

[0013] Furthermore, the object is achieved according to the invention by means of a cable gland with an above-mentioned cable with a support sleeve system, wherein at least one contact element of the cable gland contacts a cable armoring of the cable and / or a support sleeve system.

[0014] A support sleeve system, preferably pre-assembled on a cable, is proposed for use as a counterbearing and / or contact surface for electrically contacting a cable armor. The support sleeve system comprises at least one fixing means and one support means, wherein the support means can be arranged beneath the cable armor, and the fixing means can be applied to at least one end section of the cable armor to fix the support means.

[0015] Unless otherwise stated, the support sleeve system is described in an unassembled state.

[0016] An advantage of the proposed support system is that the outer diameter of the cable armoring arranged around the support system can be defined, so that the contact properties can be designed identically for different cables with the same support system or the same support sleeve system. A particularly advantageous feature is that the support sleeve system can be pre-assembled and arranged on the cable. This allows the cable with the pre-assembled support sleeve system to be conveniently provided with a cable gland, for example. If the cable gland is removed from the cable, the armoring is protected by the support sleeve system. Reassembly into a cable gland, even one with a different design, is possible, especially with the same contact properties of the cable armoring and / or the support sleeve system.Contacting properties include, for example, an outer diameter of the cable armoring, a conductivity and / or a material hardness of the support means and / or fixing means designed as a counter bearing.

[0017] The support sleeve system comprises a fixing means. Preferably, a radial force that is substantially uniform over a circumference of the cable armoring can be applied to the cable armoring by means of the fixing means. Preferably, the cable armoring and support means, more preferably the cable and support sleeve system, can be fixed by means of the fixing means in such a way that the cable armoring and support means, or the support means system and cable, cannot be displaced relative to one another. Preferably, the fixing means is a means for radially fixing the cable armoring to the support means. Preferably, the cable armoring can be fixed to the support means only by means of the fixing means. Preferably, the fixing means is designed as a single piece. Advantageously, no means other than the fixing means is required to fix the cable armoring to the support means. Preferably, the support sleeve system can be attached to the cable by means of the fixing means independently of, for example, a cable gland.Further preferably, the support sleeve system can be permanently attached to the cable by means of the fixing means. "Permanently" in the context of the invention means that the support sleeve system can be arranged on the cable in a substantially undetachable manner. A permanent arrangement of the support sleeve system on the cable is preferably designed such that at least the fixing means must be destroyed in order to detach the support sleeve system from the cable. In one embodiment, the fixing means is designed as a crimp sleeve or snap ring. For example, the snap ring comprises a spring-elastic, slotted sleeve. In another embodiment, the fixing means is designed as a shrink tube, adhesive tape, cable tie, or the like. A shrink tube is advantageously a cost-effective design by means of which the cable armor can be arranged, preferably permanently, on the support means.The fixing means is preferably designed as a crimp sleeve. A fixing means designed as a crimp sleeve has the advantage that it allows the support sleeve system to be permanently attached to the cable. This allows for easy installation and removal of the cable, for example, in a cable gland, without the risk of losing the support sleeve system or damaging the cable armor.

[0018] Crimping, as defined by the invention, refers to plastic deformation caused by a preferably radial pressure on the part to be crimped. In particular, crimping is understood to mean crimping, whereby parts are joined together by means of plastic deformation, preferably in a force-fitting and / or form-fitting manner. A crimp sleeve is therefore a sleeve designed to be plastically deformed, preferably to join it to the cable, the cable armoring, and / or the support means.

[0019] The fixing means, preferably designed as a ferrule, preferably comprises a plastically deformable material, preferably an electrically conductive material, for example a metal, preferably a brass alloy, steel, bronze and / or brass. In one embodiment, the fixing means and the supporting means comprise the same materials. The fixing means, designed as a snap ring, preferably comprises an elastically deformable material, for example spring steel or a plastic, preferably an electrically conductive plastic. The fixing means preferably comprises a rigid material. A rigid material is preferably not deformable by contact via a provided contact element. A rigid material has the advantage that contact can be made with a defined pressure, preferably without the outer diameter of the supporting means or the cable armoring being changed in the contact area.The fixing means preferably comprises an electrically conductive material, for example a metallic material. The advantage of an electrically conductive material is that the fixing means can be contacted, in particular for the dissipation of electrical currents, for example from a contact element of a cable gland. Furthermore, this advantageously creates an enlarged, defined contact surface compared to a design in which only the cable armoring can be electrically contacted. The fixing means, which is preferably designed as a shrink tube, comprises, in one design, at least one material selected from a group comprising thermoplastic elastomers, polyolefins, polyvinyl chloride, polytetrafluoroethylene, ethylene-propylene-diene rubber, and / or polyimides.

[0020] Examples are not to be regarded as exhaustive within the meaning of the invention, but can be supplemented within the scope of general technical knowledge.

[0021] The fixing means can advantageously be used to fix the support means. The fixing means is also advantageously used to fix the cable armoring to the support means. In particular, the fixing means prevents the support means from slipping out from under the cable armoring. Furthermore, in an embodiment in which the fixing means is squeezable or crimpable and can be arranged at least partially over the support means, the support means can also be squeezable, thus preventing the support means from slipping on the cable.

[0022] The fixing agent can be applied to an end section of the cable armor. Preferably, an end section of the cable armor is at least partially covered by the fixing agent. This advantageously prevents damage to the end section of the cable armor, or to a stripped cable armor. For example, a cable with stripped cable armor can be prepared with the support sleeve system for later assembly, for example, with a cable gland. For example, fraying or breakage of the ends of the cable armor can be prevented by the fixing agent.

[0023] For the purposes of the invention, an end section of the cable armoring is understood to be a stripped end section of the cable armoring, preferably a free end of the cable armoring. The end section is preferably used for contacting a cable gland, preferably a contact element in a cable gland. The end section of the cable armoring is preferably the section under which the support sleeve can be pushed.

[0024] In one embodiment, the fixing means has an inner wall. The inner wall is preferably cylindrical. Further preferably, the inner wall is electrically conductive. The inner wall is preferably designed to ensure a preferred electrical contact with the cable armoring. Advantageously, at least the inner wall can be used to dissipate electrical currents.

[0025] In one embodiment, the fixing means comprises a receptacle for at least one end section of the cable armoring. The receptacle can preferably be a through-opening of the fixing means, which is preferably hollow-cylindrical. The fixing means is preferably designed in the shape of a pipe section or a ring. The fixing means preferably forms an annular space which serves as a through-opening for a cable. The fixing means preferably comprises an inner wall which surrounds the receptacle. The receptacle preferably extends centrally through the fixing means along the longitudinal axis of the fixing means. Advantageously, the cable armoring can be easily inserted into the receptacle. Preferably, the cable can be arranged in the receptacle with the stripped cable armoring. Further preferably, the support sleeve can be arranged in the receptacle of the fixing means.

[0026] The support sleeve system comprises a support means that can be arranged beneath a cable armor. Preferably, the support means ensures a defined diameter of the cable armor, preferably in a contact area in which, for example, in an intended use, a contact element of a cable gland is intended to preferably electrically contact the cable armor.

[0027] The support means is preferably a cylindrical sleeve, preferably a hollow-cylindrical sleeve. The support means preferably comprises a circular-cylindrical outer shell. The support means further preferably comprises a circular-cylindrical inner shell. The advantage of the cylindrical design is that a contact area is formed over the entire length of the support means, which contact area preferably has the same diameter.

[0028] The support means preferably comprises a rigid material that is preferably non-deformable under at least the pressure caused by a contact element, for example a cable gland. This advantageously ensures that the contact or the contact force exerted by the contact element remains constant. The contact force preferably remains substantially constant over the service life of a contact element, for example a cable gland, connected to the cable having the support sleeve system. Further advantageously, the contact between the contact element and the cable armoring has the same contact properties along the support sleeve. This creates a large tolerance range within which the contact element can contact the cable armoring.

[0029] The term "essentially" indicates a tolerance range that is acceptable to a person skilled in the art from an economic and technical point of view, so that the corresponding feature can still be recognized or realized as such.

[0030] The support means preferably comprises an electrically conductive material, for example a metal, preferably copper, a copper alloy, steel, brass, an electrically conductive plastic, and / or bronze. The advantage of the electrically conductive material is that it improves the dissipation of electrical currents from the cable armoring. Particularly in cable armorings with a wide mesh, the electrically conductive support means can promote the flow of electrical current. The material of the support means can be the same as or different from the material of the fixing means.

[0031] In one embodiment, it is provided that the fixing means and the support means are designed as one or two parts. One-piece in the sense of the present invention means that the support means and the fixing means form a unit, so that the fixing means is preferably pre-assembled and held on the support means. In an embodiment in which the support means and the fixing means are designed as one piece, the fixing means is, for example, soldered or welded to the support means. The advantage of this embodiment is that the support means and the fixing means are captively connected to one another. The receptacle for the fixing means for the cable reinforcement is preferably formed by an annular space between the inner wall of the fixing means and the outer wall of the support means. The shoulder preferably forms a floor region of the annular space. The annular space preferably comprises a base against which the cable reinforcement can preferably be abutted.Advantageously, by inserting the cable armor into the annular space between the support and the fixing means, a defined length, preferably starting from one end of the cable armor, can be secured by the fixing means and / or contacted by the support. Preferably, the support and / or the fixing means comprise a stop. This advantageously allows the cable armor to be positioned precisely.

[0032] In one embodiment, it is provided that the support means can be arranged in the fixing means. The support means can preferably be arranged in the receptacle of the fixing means. The fixing means can preferably be arranged above the support means. For example, during assembly, the fixing means can be threaded onto the cable. The support means can also be threaded onto the cable, wherein the support means can be arranged at least partially beneath the cable armoring. If, for example, the fixing means is threaded onto the cable before the support means and, in a first assembly step, is pushed further onto the cable than the support means, the support means can be pushed into a desired position after the support means has been arranged at least partially beneath the cable armoring. This advantageously involves smoothing the end region of the cable armoring, which may have been widened or bent over by arranging the support means beneath the same.

[0033] The nested design of the support means and the fixing means advantageously creates a compact system. Furthermore, a defined electrical connection is advantageously created between the support means and the fixing means and / or between the cable armoring and the fixing means, particularly if the fixing means itself is at least partially crimped onto the support means and / or the fixing means exerts a radial force on the cable armoring.

[0034] In one embodiment, it is provided that the cable armoring can be squeezed onto the support means by means of the fixing means. In a further embodiment, it is provided that the cable armoring can be pressed onto the support means by means of the fixing means, i.e., a force is applied by means of the fixing means that holds the cable armoring at least force-fittingly on the support means. This advantageously achieves a defined, preferably permanent connection between the cable armoring and the support sleeve system. The connection of the cable armoring and the support sleeve system is particularly advantageous for pre-assembly of the cable, for secure assembly and / or repeated disassembly and reassembly of the cable, preferably with a cable gland.

[0035] In one embodiment, the support means has an outer wall. In one embodiment, it is provided that the fixing means has an inner wall and the support means has an outer wall, wherein the inner wall and the outer wall can be arranged substantially concentrically with one another. In particular, the support means and the fixing means can be arranged concentrically with one another if they can be squeezed or pressed together. For example, the support means and the fixing means can be arranged concentrically with one another if the cable armoring can be fixed to the support means by means of the fixing means, for example, squeezed or pressed onto the support means.

[0036] In one embodiment, the support means has an outwardly projecting, at least partially circumferential shoulder onto which the fixing means can be placed. The shoulder preferably comprises a radially outwardly projecting accumulation of material and / or a wall. More preferably, the shoulder is designed to be completely circumferential. More preferably, the shoulder is arranged on an outer wall of the support means. More preferably, the shoulder forms an end face of the support means on one side. The shoulder advantageously enables the precise positioning of the support means and the fixing means relative to one another. The fixing means can preferably be placed on the at least partially circumferential shoulder of the support means, in particular when the support means is arranged in the receptacle of the fixing means. Furthermore, the shoulder advantageously simplifies the assembly of the support sleeve system because it represents an assembly aid or positioning aid.The shoulder preferably functions as a stop. The shoulder preferably forms the stop for the end of the cable armor. Furthermore, the cable armor can be optimally positioned between the support means and the fixing means, for example, by pushing the support means under the cable armor until the end section or the free end of the cable armor abuts the shoulder or ends near it and is preferably completely covered by the fixing means.

[0037] In an exemplary embodiment of the support sleeve system, it comprises a sleeve-shaped support means and a sleeve-shaped fixing means, wherein the support means can preferably be received in a receptacle of the fixing means. For assembly of the support sleeve system, the support means of the support sleeve system can be arranged under an end section of a cable armoring, preferably under a free end of the cable armoring, of a cable. The cable armoring can thereby be expanded in a defined manner in the region of the support sleeve system. The fixing means, which is designed as a crimp sleeve, for example, is arranged partially over the end section. As long as the fixing means is in an uncrimped state, it can be freely moved or positioned over the cable armoring and the support means.

[0038] The fixing device can be arranged in an assembly position, for example. To facilitate the arrangement of the fixing device in the assembly position on the support device, the support device has, for example, a circumferential shoulder at its end protruding from the cable armor. The shoulder protrudes radially outward far enough that the uncrimped fixing device can be placed onto it. This enables optimal positioning of the fixing device relative to the support device. The end section of the cable armor is arranged, for example, in a receptacle of the fixing device. The inner wall of the fixing device and the outer wall of the support device enclose the end section of the cable armor.

[0039] In an exemplary assembled state, the fixing device is crimped to the cable armor and the support sleeve in the installed position. This ensures secure electrical contact with the cable armor, and the support sleeve system is firmly connected to the cable. In the exemplary crimped state of the fixing device, the support sleeve is also deformed by the crimping of the fixing device, creating a force-locking and form-locking connection between the fixing device and the support sleeve. Furthermore, the cable armor is permanently held between the support sleeve and the fixing device.

[0040] Furthermore, a method for assembling, preferably for pre-assembling, a support sleeve system described above is proposed, which comprises the steps:

[0041] - Stripping a cable to expose a cable armor,

[0042] - threading a fixing means of the support sleeve system and a supporting means of the support sleeve system onto the cable in such a way that the supporting means is arranged at least partially under the cable armouring and the fixing means is arranged at least partially over an end section of the cable armouring, and

[0043] - force-locking and / or form-locking connection of the fixing device with the cable reinforcement.

[0044] In one embodiment, the cable pre-assembled in this way is advantageously transported to a place of use. In one embodiment, it is provided that the fixing means is connected to the cable in a force-fitting and / or form-fitting manner. In one embodiment, it is provided that the fixing means is connected to the support means in a force-fitting and / or form-fitting manner. For example, the fixing means is crimped. In a further embodiment, in which the fixing means is designed as a snap ring, for example, the fixing means is elastically expanded and, after the cable armoring has been arranged in the receptacle of the fixing means, is released. In a further embodiment, it is provided that the fixing means is designed as an adhesive tape and that this is adhered around the end region of the cable armoring.For example, by means of the fixing means designed as an adhesive tape, the cable armoring is glued to a cable core, for example comprising a sheath and / or at least one wire.

[0045] The fixing means is connected to the cable armoring at least partially on or along the cable extension, adjacent to the support means. Preferably, the cable armoring is deformed by the fixing means in such a way that the support means is prevented from slipping out from under the cable armoring.

[0046] In an exemplary embodiment of the method for assembling a support sleeve system with a cable, the cable is stripped in a first step, exposing an end section of the cable armoring. For example, the fixing means and the support means are threaded onto the cable. In a further step, the fixing means is pushed over the cable armoring. The support means is then pushed at least partially under the cable armoring. For example, the fixing means is then placed on the circumferential shoulder of the support means so that the end section of the cable armoring is at least partially arranged between the support means and the fixing means. In a further exemplary step, the fixing means is squeezed or crimped so that a force-fitting and / or form-fitting connection is created between the fixing means, cable armoring and support means.

[0047] Furthermore, a method for assembling a cable gland is proposed, which comprises the steps of: assembly as described above, preferably pre-assembly, of a support sleeve system on a cable,

[0048] Threading a cable gland onto the cable or inserting the cable with the mounted support sleeve system into a cable gland in such a way that at least one contact element electrically contacts the cable armoring in the region of the support means of the support sleeve system and / or electrically contacts the fixing means of the support sleeve system.

[0049] In one embodiment, the pre-assembled cable is mounted with a cable gland after pre-assembly. In an exemplary embodiment, a cable gland is arranged on the cable. The cable gland has, for example, two contacting elements, both of which contact the cable armoring in the area of ​​the support element. The support element creates an abutment that enables secure contact using the spring-shaped contacting elements.

[0050] In another exemplary embodiment of the cable gland, the cable is positioned with the support sleeve system in such a way that a first contacting means contacts the cable armoring in the area of ​​the support means. A second contacting means, for example, contacts the fixing means, which is electrically connected to the cable armoring.

[0051] Furthermore, a cable with a support sleeve system described above is proposed, wherein a support means of the support sleeve system is arranged at least partially under a stripped cable armoring of the cable and wherein an end section of the cable armoring is arranged in a fixing means of the support sleeve system and fixed by means of the fixing means.

[0052] The proposed cable preferably has the support sleeve system in an assembled state.

[0053] The support sleeve system preferably comprises at least one fixing means and one support means, wherein the support means is arranged under the cable reinforcement and the fixing means for fixing the support means is applied to at least one end section of the cable reinforcement.

[0054] The fixing means is designed, for example, as a crimp sleeve. A fixing means designed as a crimp sleeve has the advantage that it permanently fastens the support sleeve system to the cable. A permanent, particularly non-destructively removable, fastening of the support sleeve system to the cable can also be achieved by designing the fixing means, for example, as a shrink tube or a crimp sleeve. The outer diameter of the cable armoring arranged around the support means is defined by the support means, preferably in the area of ​​the support means.

[0055] The fixing means is used to secure the support means. In particular, the fixing means prevents the support means from slipping out from under the cable armoring. Furthermore, in one embodiment, the fixing means is advantageously arranged at least partially on the support means, so that the support means is at least partially crimped together with the fixing means. This advantageously prevents the support means from slipping on the cable.

[0056] The fixing agent is applied to an end section of the cable armor. Preferably, an end section of the cable armor is covered by the fixing agent. This advantageously prevents damage to the end section of the cable armor, in particular to a stripped cable armor.

[0057] In one embodiment, the support means is arranged in the fixing means. Preferably, the support means is arranged in the receptacle of the fixing means. Preferably, the fixing means is arranged above the support means. For example, the fixing means is threaded onto the cable. The support means is also threaded onto the cable, being arranged at least partially beneath the cable armoring.

[0058] In one embodiment, the cable armoring is crimped to the support means by means of the fixing means. In another embodiment, the cable armoring is pressed onto the support means by means of the fixing means, i.e., a force is applied by means of the fixing means that holds the cable armoring force-fitted to the support means. The fixing means preferably presses onto the cable armoring using an elastic force. This advantageously achieves a defined, preferably permanent, connection between the cable armoring and the support sleeve system.

[0059] In one embodiment, it is provided that the fixing means has an inner wall and the supporting means has an outer wall, wherein the inner wall and the outer wall are arranged substantially concentrically to one another. In particular, the supporting means and the fixing means are arranged concentrically to one another when they are squeezed or pressed together. For example, the supporting means and the fixing means are arranged concentrically to one another when the cable armouring is fixed to the supporting means by means of the fixing means, for example squeezed or pressed onto the supporting means. In one embodiment, it is provided that the supporting means has an outwardly projecting, at least partially circumferential shoulder on which the fixing means is placed. In this embodiment, the supporting means and the fixing means are advantageously optimally positioned relative to one another.Preferably, the fixing means is placed on or against the at least partially circumferential shoulder of the support means, particularly when the support means is arranged in the receptacle of the fixing means. Preferably, the cable reinforcement is arranged between the support sleeve and the fixing means. Further preferably, the cable reinforcement is applied substantially to the shoulder of the support means.

[0060] Furthermore, a cable gland with an above-mentioned cable with a support sleeve system is proposed, wherein at least one contact element of the cable gland contacts a cable armoring of the cable and / or a support sleeve system.

[0061] In one embodiment, the support means and / or fixing means comprise an electrically conductive material. Advantageously, the support means and / or fixing means are electrically connected to the contact element, in particular for discharging electrical currents.

[0062] An example cable gland that can be arranged on the cable has two contact elements, both of which contact the cable armoring in the area of ​​the support element. The support element creates an abutment that enables secure contact using the preferably spring-shaped contact elements.

[0063] In another exemplary embodiment of the cable gland, it can be positioned such that a first contacting means contacts the cable armoring in the area of ​​the support means. A second contacting means contacts the fixing means, which is electrically connected to the cable armoring.

[0064] In a further exemplary embodiment, the cable gland has exactly one contacting means which is electrically connected to the cable armouring in the region of the support means or to the fixing means.

[0065] Furthermore, the use of a support sleeve system as defined above for pre-assembly on a cable is proposed. In one embodiment, the cable pre-assembled with the support sleeve system is used with a cable gland.

[0066] Furthermore, the use of an above-mentioned support sleeve system as a counter bearing and / or contact surface for electrical contact with a contact element of a cable gland is proposed.

[0067] In one embodiment, the contact element exerts a force on the cable armoring in order to make electrical contact with the cable. In order to counteract deformation of the cable armoring, the support sleeve system, in particular the support means, preferably functions as a counterbearing for the force preferably applied directly to the cable armoring by the contact element. If the contact element makes direct contact with the cable armoring, the contact element and cable armoring come into direct contact. A force flow preferably occurs from the contact element through the cable armoring into the support means. In a preferred embodiment, the fixing means functions directly as a counterbearing for the contact element, namely when the contact element contacts the cable at least partially in the region of the fixing means. A force flow preferably occurs from the contact element through the fixing means and through the cable armoring into the support means.In a further embodiment, in which the contact element is arranged on the cable below the support element along a cable extension, a force flows from the contact element through the fixing means to the cable armor. In a further embodiment, a force flows both through the fixing means to the cable armor and via the fixing means through the cable armor into the support means, namely when the fixing means is connected to the cable armor partially below and partially on the support means along a cable extension. By using the support sleeve system as a counterbearing, cables with the same contact properties can be advantageously produced.

[0068] Further advantageous embodiments will become apparent from the following drawings. However, the developments presented therein are not to be interpreted as limiting; rather, the features described therein can be combined with one another and with the features described above to form further embodiments. Furthermore, it should be noted that the reference numerals used in the description of the figures do not limit the scope of the present invention, but merely refer to the exemplary embodiments shown in the figures. Identical parts or parts with the same function have the same reference numerals below. They show:

The support means 14 is therefore not visible in Fig. 1A, and the reference symbol is therefore provided with a dashed line. The cable armor 32 is expanded in a defined manner in the region of the support sleeve system 14. A fixing means 12, designed as a crimp sleeve, is arranged partially over the end section 34. In Fig. 1A, the fixing means 12 is in an uncrimped state in which it is freely movable over the cable armor 32 and the support means 14.

[0075] In Fig. 1B, the fixing means 12 is crimped to the free end of the cable armor 32 and the support means 14. This ensures secure electrical contact with the cable armor 32, and the support sleeve system 10 is firmly connected to the cable 30.

[0076] Fig. 1 C and Fig. 1 D each show a cable gland 40 arranged on the cable 30 in different positions, which is described in detail in Fig. 2 C and Fig. 2 D.

[0077] Fig. 2 shows the different assembly states A, B, C, and D from Fig. 1 in a partially sectioned view. Fig. 1A shows that the support means 14 is arranged beneath the cable armor 32 of the cable 30. The fixing means 12, in the uncrimped state, is arranged on the support means 14, with the cable armor 32 being arranged at least partially between the support means 14 and the fixing means 12.

[0078] Fig. 2B shows the crimped state of the fixing means 12. The support means 14 is also deformed when the fixing means 12 is crimped, creating a force-locking and form-locking connection between the fixing means 12 and the support means 14. Furthermore, the free end of the cable reinforcement 32 is permanently held between the support means 14 and the fixing means 12.

[0079] Fig. 2C shows a cable gland 40 arranged on the cable 30. The cable gland 40 has two contacting elements 42 and 44, both of which contact the cable armoring 32 in the region of the support element 14. The support element 14 creates an abutment that enables secure contacting by means of the spring-shaped contacting elements 42 and 44.

[0080] Fig. 2 D shows an alternative arrangement of the cable gland 40 on the cable 30. The cable gland 40 is positioned such that the contacting means 42 contacts the cable armor 32 in the region of the support means 14. The contacting means 44 contacts the fixing means 12, which is electrically connected to the cable armor 32.

[0081] Fig. 3 shows section III of Fig. 2 A. The support element has a circumferential shoulder 15 at its end protruding from the cable armor 32. The shoulder 15 protrudes radially outward far enough for the fixing element 12 to be placed onto it. This enables optimal positioning of the fixing element 12 relative to the support element 14. The end section 34 of the cable armor 32 is arranged in a receptacle 16 of the fixing element 12. The inner wall 18 of the fixing element 12 and the outer wall 19 of the support element 14 enclose the end section 34 of the cable armor 32.

[0082] Fig. 4 shows section IV from Fig. 3. It can be seen that the fixing means 12 is placed on the circumferential shoulder 15 of the support means 14 in order to simplify assembly of the support sleeve system 10.

[0083] Fig. 5 shows an assembly sequence A, B, C, D and E for the assembly of a support sleeve system 10 with a cable 30 in a partially sectioned view. In step A, the cable 30 is stripped, exposing an end section 34 of the cable armor 32. The fixing means 12 and the support means 14 are threaded onto the cable. In step B, the fixing means 12 are pushed over the cable armor 32. In step C, the support means 14 is at least partially pushed under the cable armor 32. Then, in step D, the fixing means 12 is placed onto the circumferential shoulder 15 of the support means 14, so that the end section 34 of the cable armor 32 is at least partially arranged between the support means 14 and the fixing means 12. In step E, the fixing means 12 is squeezed or crimped so that a force-fitting and form-fitting connection is created between the fixing means 12, the cable reinforcement 32 and the support means 14.

[0084] The proposed support sleeve system 10 allows for simple and secure pre-assembly of cables, which can be screwed together, for example, using a cable gland 40. The support means 14 secured beneath the cable armor 32 and the fixing means 12 create electrical abutments that enable secure and reliable electrical contacting, for example, using resilient contact elements 42, 44.
