Description

[0001] The invention relates to an electrical cable for an automation system and a repair method for the electrical cable of the automation system.

[0002] From EP 2 608 321 B1, a connector with a compression sleeve and an inner sleeve is known. The inner sleeve has a stepped slot and extends circumferentially around an axis. Electrical cables of a shielded conductor are guided through the inner sleeve. On the outside, a shield conductor of the shielded cable rests against the inner sleeve when the contact device is mounted and is enclosed on the outside by a ferrule.

[0003] Furthermore, a contact device for a coaxial cable is known from US 7,588,460 B2. The contact device has a gripping ring that is enclosed circumferentially by a connector body. The gripping ring contacts both an outer insulation and a shield conductor of the coaxial cable and is pressed onto the outside of the coaxial cable by a sealing sleeve.

[0004] Furthermore, numerous other contact devices for contacting a coaxial cable are known in the prior art. To prevent tampering and unintentional disassembly of these contact devices, they are often additionally enclosed by a protective sleeve made of melted plastic. This sleeve can only be removed from the contact device by means of a destructive process; moreover, the molten plastic frequently penetrates the contact device and can reduce electrical contact between individual components or increase susceptibility to faults. Disassembly of the plastic sleeve also often leads to further damage to other components of the contact device during the disassembly process.

[0005] The purpose of the invention is to provide a tamper-proof electrical cable for an automation system with an easy-to-repair contact device.

[0006] This problem is solved by means of an electrical cable for an automation system according to claim 1 and by means of a repair method according to claim 10. Advantageous embodiments are specified in the dependent claims.

[0007] It was recognized that an improved electrical cable for data communication and / or the transmission of electrical power in an automation system can be provided by the electrical cable comprising a contact device and a shielded cable with a shield conductor. The contact device has at least one shield sleeve and a crimp sleeve. The shield sleeve has a crimp section extending circumferentially about an axis and a shield contact spring assembly arranged axially offset from the axis with at least one first shield contact spring. The crimp section is connected to the shield contact spring assembly and has a crimping surface and a receiving groove arranged in the crimping surface on an outer circumferential side of the shield sleeve.The crimp sleeve is pressed onto the crimping surface of the crimping section of the shielding sleeve, so that the shield conductor is arranged radially between the crimp sleeve and the shield contact spring assembly of the shielding sleeve. The shield contact spring assembly is pre-tensioned and presses the shield conductor with a clamping force against a sleeve contact surface formed on an inner circumferential side of the crimp sleeve, thus making electrical contact with the shield conductor. Furthermore, the receiving groove and the crimp sleeve form a tool receiving space.

[0008] In this design, the crimp sleeve is securely attached to the shielding sleeve by a force-fit connection that prevents manipulation and therefore cannot be removed from the shielding sleeve without causing damage.

[0009] This design has the advantage that the crimp sleeve can only be cut open using a separating tool, thus releasing the crimp of the sleeve onto the crimping surface. Manual manipulation of the crimp sleeve by unauthorized personnel is therefore easily detectable.

[0010] To remove the crimp sleeve, the cutting tool can be inserted into the tool receiving chamber while a cutting slot is being made in the crimp sleeve, without damaging the shield sleeve with the cutting tool.

[0011] This design has the further advantage that even if the crimp sleeve is removed by machining, other components of the contact device and the shield cable are not mechanically damaged and can be reused.

[0012] The crimp sleeve pressed onto the shield sleeve also provides additional protection for the contact device against unintentional manipulation, or manipulation of the contact device, for example by an inadequate disassembly attempt, is easily recognizable by a specialist.

[0013] Furthermore, the crimp sleeve, which is hollow and continuous in the circumferential direction, protects the contact element from the ingress of dirt and moisture. This ensures a reliable electrical connection within the cable's contact element.

[0014] Furthermore, the application of a protective sleeve, for example made of plastic, to the contact device using an injection molding process can be avoided, thereby preventing unwanted ingress of molten plastic into the contact device and a potentially associated increased electrical contact between individual components of the contact device caused by the intruding plastic.

[0015] In a further embodiment, the shielding sleeve has a first spring gap and a second spring gap laterally to the first shielding contact spring in the circumferential direction, wherein the first spring gap and the second spring gap extend along the axis, and the first spring gap and / or the second spring gap are aligned with the receiving groove. This design has the advantage that when machining the separation slot into the crimping sleeve, the separating tool can continue to advance and can penetrate into the first spring gap without further damaging the shielding sleeve. The spring gap also ensures that the separating tool does not unintentionally damage the shielding sleeve, so that the shielding sleeve can be reused even after the contact device has been disassembled.

[0016] In a further embodiment, the contact device has a contact carrier and a contact element arrangement with at least one first contact element, wherein the first contact element extends through the contact carrier, wherein the shielding sleeve radially surrounds the contact carrier at least partially on the outside, wherein the shielding sleeve has a coding receptacle extending along the axis between the second spring gap and the receiving groove, wherein the contact carrier engages in the coding receptacle with a first coding nose.

[0017] In a further embodiment, the crimp sleeve is aligned with a predefined circumferential orientation relative to the axis of the shielding sleeve, and is positively locked to the shielding sleeve in a rotationally secure manner. This defined orientation allows the disassembly tool to be positioned precisely relative to the tool receptacle on the crimp sleeve during repairs. Furthermore, the rotationally secure connection prevents unintentional twisting of the crimp sleeve.

[0018] In a further embodiment, the crimp sleeve has a marking on an outer circumferential side, wherein the marking and the receiving groove are arranged circumferentially offset from each other at a predefined angle or are at least partially overlapping in the radial direction. This defined orientation allows a person qualified to use the marking to indicate the orientation of the shield sleeve relative to the crimp sleeve. The marking can be either a colored marking on the crimp sleeve and / or a geometric deformation of the crimp sleeve to mark the receiving groove.

[0019] The marking of the receiving groove on the outside of the crimp sleeve allows the electrical cable to be precisely aligned relative to the cutting tool, ensuring that the cutting tool engages in the receiving groove when the crimp sleeve is cut. In particular, the cutting tool can be placed directly onto the marking.

[0020] In another embodiment, the marking is groove-shaped. Preferably, the marking is embossed into the crimp sleeve. This design has the advantage that the groove-shaped shape effectively prevents unwanted lateral movement of the cutting tool when it is applied to the crimp sleeve, thus ensuring that the cutting tool cuts the crimp sleeve precisely at the marking. In particular, this also effectively prevents damage to the shield sleeve caused by the cutting tool, which would otherwise occur due to possible lateral movement.

[0021] In a further embodiment, the crimp sleeve has a bulge on its inner circumferential side, the bulge engaging in the receiving groove and connecting the crimp sleeve to the shielding sleeve in a torque-locking manner. The bulge ensures that unintentional rotation of the crimp sleeve relative to the shielding sleeve is prevented, thus keeping the marking on the outer circumferential side correctly aligned with the shielding sleeve. This ensures that the cutting tool can reliably penetrate the tool holder when the cutting slot is created.

[0022] In a further embodiment, the crimp sleeve has at least one first sleeve recess and preferably a second sleeve recess arranged circumferentially offset from the first sleeve recess, wherein a pulling force acting axially away from the shielding sleeve along the axis can be introduced into the crimp sleeve at the first sleeve recess and / or at the second sleeve recess. This allows the crimp sleeve to be easily pulled off the shielding sleeve in the axial direction.

[0023] In a further embodiment, the first sleeve recess and / or the second sleeve recess is arranged circumferentially offset from the marking with respect to the axis. This ensures a clearly identifiable orientation of the contact device for repair.

[0024] In a further embodiment, the contact device has a first sealing element, wherein the shield sleeve has a circumferential sealing groove on the outside of the crimping section, with the first sealing element being arranged in the sealing groove, and preferably the receiving groove opening into the sealing groove. This design has the advantage that the interior of the crimp sleeve is fluid-tightly sealed from the surroundings of the contact device by means of the second sealing element. This prevents the ingress of liquids or gases as well as dirt particles into the interior of the sleeve. This ensures reliable contact over the service life of the electrical cable. Furthermore, when the crimp sleeve is cut, the cutting tool can also penetrate the second sealing element.The second sealing element can be made of a soft, elastic material, such as a polymer, thus preventing further damage to the contact mechanism and requiring only the replacement of the second sealing element in addition to the crimp sleeve. Replacing the second sealing element is advisable anyway to ensure a reliable, long-term seal between the sleeve's interior and the environment when the crimp sleeve is replaced. The second sealing element is already pre-separated, allowing for easy and reliable removal.

[0025] In another embodiment, the shield sleeve has a shoulder that extends radially outwards and projects beyond the pressing surface in the radial direction. The crimp sleeve rests against the shoulder at its end face. The shoulder can connect to the pressing surface essentially in the axial direction. This design ensures that the crimp sleeve is easily positioned axially relative to the shield sleeve by means of the stop.

[0026] An improved repair method for the electrical cable described above can be provided by supplying a disassembly device in addition to the electrical cable described above. A cutting tool of the disassembly device acts on the crimp sleeve and creates a cutting slot extending along the axis in the crimp sleeve. The cutting slot extends radially through the crimp sleeve and opens into the tool receiving space. The cutting slot reduces the crimp of the crimp sleeve on the crimping section of the shielding sleeve in such a way that the crimp sleeve is pulled off the shielding sleeve along the axis. The separated crimp sleeve is replaced by another crimp sleeve that is continuous in the circumferential direction. The additional crimp sleeve is arranged on the shielding sleeve and pressed onto the crimping section.

[0027] This design of the repair method has the advantage that, particularly when the specified process steps are carried out in the specified order, the shielding sleeve can be separated from the crimping sleeve very easily, thus providing access to the internal structure of the contact device without the need for further process steps. Separating the shielding sleeve, which is preferably made of a metallic material, especially a material identical to that of the shielding sleeve, ensures good recyclability of the contact device.

[0028] Following the repair, almost all components of the contact assembly can be reused to rebuild the contact assembly; only an undamaged, for example a new, crimp sleeve needs to be used to replace the slotted, split crimp sleeve.

[0029] Furthermore, the individual components of the contact device can be easily separated from each other and recycled according to their materials, thus ensuring good recyclability with regard to the raw materials of the contact device.

[0030] Furthermore, the electrical cable can be mounted without the need for an overmolding step with, for example, plastic. Consequently, thermal separation of molten plastic from other components of the contact device is also unnecessary, resulting in a disassembly process with very few steps and a particularly fast procedure.

[0031] Therefore, the disassembly process can also be carried out on-site within an assembled automation system, for example in a production plant, without having to disconnect the electrical cable beforehand. This allows the shielding cable, in particular, to remain in place within the automation system and does not need to be disconnected or re-routed after the electrical cable has been repaired.

[0032] In a further embodiment, the separating tool, when creating the separation slot in the crimp sleeve, penetrates a wall of the crimp sleeve and enters the tool receiving chamber, at least partially, with the separating tool preferably being guided at a distance from the shielding sleeve within the tool receiving chamber. This ensures that the shielding sleeve is not damaged by the separating tool during the disassembly process and that the shielding sleeve can therefore be reused after disassembly of the contact device, in particular reinstalled in the contact device.

[0033] In another embodiment, the separation slot is milled or sawn. These methods are particularly well suited for creating the separation slot by machining and weakening the press-fit sleeve.

[0034] In another embodiment, the additional crimp sleeve is defined and aligned in the circumferential direction to the shield sleeve, and after alignment of the additional crimp sleeve, the additional crimp sleeve is pressed onto the crimp section.

[0036] Fig. Figure 1 shows a schematic representation of an electrical cable 10 according to a first embodiment.

[0037] The electrical cable 10 can, for example, be designed for data communication and / or for the transmission of electrical power. In particular, the electrical cable 10 can be used in an automation system 15 to connect, for example, individual participants of the automation system 15 to each other and / or to a control device for data communication and / or power transmission.

[0038] The electrical cable 10 points in Fig. 1 a contact device 20 and a shielded cable 25. The contact device 20 can, for example, be connected to a mating contact device 30 (schematically shown in) when the electrical cable 10 is mounted. Fig. The mating contact device 30 is designed to correspond to the contact device 20 and can, for example, be part of a component, such as a participant or the control device, of the automation system 15.

[0039] The contact device 20 extends along an axis 35 when assembled. For ease of understanding regarding the arrangement of individual components of the electrical cable 20, reference is made to the axis 35 in the following. The axis 35 can also be referred to as the assembly axis or plug-in axis.

[0040] Radially on its outer side with respect to the axis 35, the shield cable 25 has an outer cable surface 40. An outer cable insulation 45, made of an electrically insulating material, adjoins the outer cable surface 40.

[0041] The shielded cable 25 has at least one shield conductor 50, wherein the shield conductor 50 connects radially to the inner surface of the outer cable insulation 45. The electrically conductive shield conductor 50 can, for example, be designed as a braided shield and extends circumferentially around the axis 35. The shield conductor 50 can, for example, be formed from a braid of copper wires, which may be tinned. Alternatively, the shield conductor 50 can, for example, be formed from an electrically conductive foil.

[0042] With respect to axis 35, an inner cable insulation 55 is attached to the inside of the shield conductor 50. The inner cable insulation 55 can, for example, be formed from a foil wrapping. Both the inner cable insulation 55 and the outer cable insulation 45 electrically insulate the shield conductor 50 from the surroundings 60 of the shield cable 25.

[0043] Radially on the inside side of the inner cable insulation 55, the shield cable 25 can have a cable assembly 65. The cable assembly 65 can have one or more individual cables 70, wherein the individual cables 70 are in Fig. 1 are only indicated.

[0044] The individual cables 70 can be arranged parallel to the axis 35, or can, for example, be grouped together in pairs as a twisted pair. Each of the individual cables 70 has core insulation and an electrical conductor. The core insulation is arranged circumferentially around the electrical conductor and electrically insulates the conductor. The number of individual cables 70 in the cable arrangement 65 can, for example, be four individual cables 70. However, any other number of individual cables 70 can also be provided in a cable arrangement 65.

[0045] The individual cable 70 can, for example, be configured to transmit a data signal from the automation system 15, in particular a digital signal. It is also possible that at least some of the individual cables 70 can transmit electrical power with a current of 0.1 amperes to 20 amperes between participants in the automation system 15. Furthermore, the individual cables 70 of the cable arrangement 65 can have different cross-sectional areas, depending on whether the individual cable 70 is used to transmit electrical power or a data signal.

[0046] The shield conductor 50 protects the cable arrangement from the coupling of electromagnetic influences, for example by actuators of a production plant controlled by the automation system 15, and the shield conductor 50 reduces or prevents electromagnetic radiation from the cable arrangement 65 into the environment, in particular to the participants of the automation system 15.

[0047] In the context of using the electrical cable 10 within the automation system 15, it may be necessary to bridge relatively long distances of 5 meters to 500 meters using the shielded cable 25. Preferably, the shielded cable 25 is continuous, so that the electrical conductors extend continuously from the contact device 20 to the opposite end of the shielded cable 25.

[0048] At the opposite end of the electrical cable 10, analogous to the one in Fig. 1 shown contact device 20, for example, also another contact device (in Fig. (1 not shown) arranged, for example identical to the one in Fig. 1 shown contact device 20 is trained.

[0049] Fig. 2 shows a perspective view of the in Fig. 1 electrical cable shown 10.

[0050] The contact element 20 is elongated and extends along the axis 35 between a contact side 85 and a cable side 90. The contact side 85 faces the mating contact element 30 and thus away from the shielded cable 25. The cable side 90 faces away from the mating contact element 30 and thus away from the shielded cable 25 (dashed line in Fig. 2 indicated) turned towards.

[0051] The contact device 20 comprises a coupling element 95, a shielding sleeve 100, and a crimping sleeve 105. The coupling element 95 connects axially to the contact side 85. Axially opposite, the crimping sleeve 105 connects to the cable side 90. The shielding sleeve 100 is arranged axially with respect to the axis 35 between the coupling element 95 and the crimping sleeve 105.

[0052] Together, the overlock element 95, the shield sleeve 100 and the crimp sleeve 105 define a contact housing interior 109, with the shield cable 25 being inserted into the contact housing interior 109 on the cable side 90.

[0053] In order to be able to use the electrical cable 10 particularly in EX areas or damp areas, the contact housing interior 109 is preferably sealed against the environment 60 of the electrical cable 10.

[0054] Fig. Figure 3 shows an exploded view of the [unclear text] in the Fig. 1 and Fig. 2 electrical cables shown 10.

[0055] The contact device 20 additionally comprises an insulating body 110, a contact carrier 115, a contact element arrangement 120, preferably an insert 125, and a sealing element arrangement 130. The sealing element arrangement 130 can, for example, comprise a first sealing element 135 and / or a second sealing element 140 and / or preferably a third sealing element 145.

[0056] The contact element arrangement 120 comprises at least one first contact element 150 and a second contact element 155 arranged circumferentially offset from the first contact element 150 with respect to the axis 35. Preferably, the number of contact elements 150, 155 corresponds to the number of individual cables 70, wherein, in the assembled state of the contact device 20, each contact element 150, 155 is electrically connected to the associated individual cable 70 on the shield cable 25.

[0057] The contact element arrangement 120 is arranged in the contact carrier 115, whereby a position of the respective contact element 150, 155 is secured by the contact carrier 115.

[0058] Fig. Figure 4 shows a perspective view of the insulating body 110.

[0059] The insulating body 110 extends along the axis 35. The insulating body 110 has a first insulating body section 195 and a second insulating body section 200. In the first insulating body section 195, the insulating body 110 is designed as a hollow body.

[0060] The insulating body 110 has a first coding nose 160, which is arranged on an outer circumferential side 165 of the insulating body 110 and extends radially outwards.

[0061] Preferably, the insulating body 110 has several first coding lugs 160 arranged in a common plane perpendicular to the axis 35. The first coding lugs 160 are arranged circumferentially offset from one another. In this embodiment, for example, the two first coding lugs 160 are arranged with an offset of, for example, 180°.

[0062] Offset axially from the first coding lug 160, the insulating body 110 has a circumferential first groove 170 on its outer circumferential side 165. The first groove 170 is open radially outwards on its outer circumferential side 165.

[0063] In the axial direction, a first slot-shaped recess 185 can be arranged on the side facing away from the first groove 170, following the first coding nose 160.

[0064] The first recess 185 extends, for example, in a radial direction essentially completely through a wall of the insulating body 110. Subsequently, in an axial direction on the side facing away from the first groove 170, the first recess 185 extends, for example, to a second insulating body end face 190 in an axial direction.

[0065] Fig. 5 shows a perspective view from an opposite side Fig. 4 changed viewing angles on the insulating body 110.

[0066] In the first insulating body section 195, the insulating body 110 radially encloses a support receiving space 187 on its inner side. The support receiving space 187 is, for example, open at the second insulating body end face 190 and extends axially towards the first insulating body end face 186. The support receiving space 187 terminates at a distance from the first insulating body end face 186 and at a receiving base 205.

[0067] Fig. Figure 6 shows a sectional view along a [unclear] in Fig. Section plane AA shown in 4 through the in Fig. 4 insulating bodies 110 shown, wherein in Fig. 6. For example, hatching of the cut surface of the insulating body 110 is omitted.

[0068] The insulating body 110 has at least one first contact element receptacle 206 and a second contact element receptacle 207 arranged offset from the first contact element receptacle 206 in the second insulating body section 200. Preferably, the first and second contact element receptacles 206, 207 are selected according to the number of contact elements 150, 155. The first contact element receptacle 206 and / or the second contact element receptacle 207 each extend axially from the first receptacle base 205 to the first end face 186 of the insulating body and can, for example, be designed as a bore.

[0069] Fig. Figure 7 shows a perspective view of the umbrella sleeve 100.

[0070] The umbrella sleeve 100 extends between a first umbrella sleeve end 210 and a second umbrella sleeve end 215 along the axis 35. The umbrella sleeve 100 is, for example, designed as a body of revolution and circumferentially encloses an inner umbrella sleeve space 249. The inner umbrella sleeve space 249 is, for example, open in the axial direction at both the first umbrella sleeve end 210 and the second umbrella sleeve end 215.

[0071] A first engagement section 220 extends axially from the first end of the umbrella sleeve 210. The first engagement section 220 can be hollow and cylindrical.

[0072] A shoulder 225 adjoins the first engagement section 220 on a side facing the second end 215 of the shielding sleeve, the shoulder 225 having a first contact surface 230 on the side facing the first end 210 of the shielding sleeve. The first contact surface 230 can be circumferential and preferably extends in a plane perpendicular to the axis 35.

[0073] On the side of the paragraph 225 facing away from the first end of the shield sleeve 210, the paragraph 225 has a second contact surface 235, wherein the second contact surface 235 is aligned parallel to the first contact surface 230.

[0074] In the axial direction, a crimped section 240 adjoins the shoulder 225 on the side facing away from the first shield sleeve end 210. The crimped section 240 terminates at a distance from the second shield sleeve end 215, with a shield contact spring assembly 280 arranged in a spring section 245 between the second shield sleeve end 215 and the crimped section 240. The spring section 245, which adjoins the crimped section 240 and extends along the axis 35 to the second shield sleeve end 215, comprises a shield contact spring assembly 280.

[0075] Fig. Figure 8 shows a longitudinal section through the in Fig. 7 shown umbrella sleeve 100, wherein in Fig. 8. For example, hatching of the cut surfaces of the umbrella sleeve is omitted.

[0076] The shielding sleeve 100 is made of an electrically conductive material, in particular an aluminum and / or copper alloy. The shielding sleeve 100 is preferably manufactured in one piece and made of a single material.

[0077] For example, a first locking groove 255 is arranged in an outer circumferential side 250 of the first engagement section 220 of the shield sleeve, spaced apart from both the first shield sleeve end 210 and the first contact surface 230. The first locking groove 255 preferably extends circumferentially around the axis 35 and is radially open to the outside. The first locking groove 255 can, for example, have a rectangular groove profile.

[0078] Furthermore, the first end of the umbrella sleeve 210 may be chamfered.

[0079] The shoulder 225 projects radially beyond the circumferential side 250 of the first engagement section 220 of the shield sleeve. Likewise, the shoulder 225 can project radially beyond the crimping section 240.

[0080] A sealing groove 260 can be arranged in the press-fit section 240, wherein the sealing groove 260 is located near or adjacent to the second contact surface 235. The sealing groove 260 is radially open to the outside.

[0081] A second groove 265 can be arranged in the press-fit section 240 on the side of the sealing groove 260 facing the second end of the shield sleeve 215, wherein the second groove 265 is formed circumferentially around the axis 35 and is preferably narrower in the radial direction than the sealing groove 260.

[0082] The crimping section 240 further comprises a crimping surface 270 radially outside on the circumferential side 250 of the shield sleeve, which, for example, has a substantially cylindrical shape. The crimping surface 270 can, particularly in the axial direction, connect to the sealing groove 260 on the side facing away from the second shield sleeve end 215 and extend towards the second shield sleeve end 215 as far as the shield contact spring assembly 280.

[0083] At a transition 266 between the crimping section 240 and the spring section 245, the outer diameter of the shielding sleeve 100 is reduced. The shielding sleeve 100 may be chamfered at the transition 266. The crimping surface 270 ends axially at the transition 266.

[0084] Fig. Figure 9 shows a perspective view of the umbrella sleeve 100 from a Fig. 7 different perspectives.

[0085] The shield contact spring assembly 280 comprises at least one first shield contact spring 290 and a second shield contact spring 295 arranged circumferentially offset from the first shield contact spring 290 with respect to the axis 35. Preferably, the shield contact spring assembly 280 comprises several first and second shield contact springs 290, 295, which are spaced apart from each other circumferentially. The first shield contact spring 290 and / or the second shield contact spring 295 can be tongue-shaped and is attached at a fixed end at the transition 266 and thus to the crimped section 240. The first shield contact spring 290 and the second shield contact spring 295 can be substantially identical to each other and, for example, extend by approximately 90° around the axis 35.

[0086] The first shield contact spring 290 and / or the second shield contact spring 295 each define a first spring gap 300 and a second spring gap 301 arranged circumferentially opposite the first spring gap 300. The first spring gap 300 and the second spring gap 301 extend radially completely through the spring section 245 and spatially separate the first shield contact spring 290 from the second shield contact spring 295 circumferentially. The first spring gap 300 can have a first gap width and the second spring gap 301 a second gap width circumferentially, which may differ from the first gap width. For example, in Fig. 9 the first spring gap 300 is narrower than the second spring gap 301.

[0087] Furthermore, the first spring gap 300 and the second spring gap 301 can be arranged at a predefined first angle, for example by 90°, offset from each other to form the shield contact springs 290, 295.

[0088] The shield sleeve 100 further comprises a receiving groove 275. The receiving groove 275 extends in a straight line parallel to the axis 35 in the contact surface 270. The receiving groove 275 extends at least between the sealing groove 260 and the transition 266. The second groove 265 can extend circumferentially over the receiving groove 275. In a further embodiment, the receiving groove 275 can be extended axially to near or completely to the second contact surface 235 of the shoulder 225. In the circumferential direction, the receiving groove 275 thus interrupts the contact surface 270, so that the latter is formed in an annular shape around the axis 35.

[0089] The receiving groove 275 is bounded circumferentially by a first groove side surface 281 and a second groove side surface 282 arranged circumferentially offset from the first groove side surface 281. The receiving groove 275 has a maximum width b in the circumferential direction between the first groove side surface 281 and the second groove side surface 282.

[0090] The receiving groove 275 is radially closed inwards, so that a groove base 305 of the receiving groove 275 is spaced apart from the interior of the shielding sleeve 249 and is closed towards the interior of the shielding sleeve 249. This makes the shielding sleeve 100 rigid in the crimping section 240 in the radial direction with respect to the axis 35.

[0091] The recording unit 275 can, as in Fig. Figure 9 shows the first spring gap 300 arranged along the axis 35 in alignment with the first spring gap 300. The maximum width b can be independent of the first gap width of the first spring gap 300. The receiving groove 275 can also be arranged offset circumferentially from the first spring gap 300 and / or the second spring gap 301.

[0092] In the crimping section 240, the crimping sleeve 105 can furthermore have a coding receptacle 310, offset circumferentially from the receiving groove 275. The coding receptacle 310 is preferably configured circumferentially corresponding to the first coding lug 160 of the insulating body 110. The coding receptacle 310 can, for example, be formed as a through-slot in the crimping section 240 and open radially inside the shielding sleeve interior 249.

[0093] The coding receptacle 310 can be aligned axially with respect to the second spring gap 300 and adjoin the second spring gap 301 longitudinally on the side facing the first end of the shield sleeve 210. The coding receptacle 310 and the second spring gap 301 can be of the same width circumferentially.

[0094] The coding receptacle 310 can be shorter in the axial direction than the receiving groove 275 and thus end at a distance from the second step 275 on the side facing the first shield sleeve end 210. In particular, the coding receptacle 310 can, for example, end at the second groove 265.

[0095] In the assembled state of the contact device 20, the first coding nose 160 of the insulating body 110 engages in the respective assigned coding receptacle 310, so that the insulating body 110 is thereby aligned in a defined circumferential direction with respect to the shielding sleeve 100.

[0096] Fig. Figure 10 shows a perspective view of the [unclear] in the Fig. 1 and Fig. 2 shown crimp sleeve 105 of the contact device 20.

[0097] The crimp sleeve 105 has a sleeve-shaped wall and extends essentially in a hollow form, in particular in a sleeve- or hollow-cylindrical manner, around the axis 35. The crimp sleeve 105 has a first sleeve end 320 and a second sleeve end 325 arranged axially opposite the first sleeve end 320. The crimp sleeve 105 and its wall are continuous and uninterrupted in the circumferential direction. The crimp sleeve 105 encloses an inner sleeve space 330. On an outer circumferential side 335, the crimp sleeve 105 preferably has a marking 340, which extends, for example, parallel to the axis 35.

[0098] Furthermore, a first sleeve recess 345 can be arranged on the outer circumferential side 335 of the sleeve, spaced apart from the first sleeve end 320 and the second sleeve end 325. The first sleeve recess 345 can be formed tangentially to the outer circumferential side 335 of the sleeve and be planar.

[0099] In the embodiment, for example, the first sleeve recess 345 is arranged in the circumferential direction, for example offset by 90°, to the marking 340, provided that the marking 340 is provided.

[0100] Fig. Figure 11 shows a perspective view of the in Fig. 10. Press-fit sleeve 105 shown from another angle.

[0101] Radially opposite the first sleeve recess 345, the crimp sleeve 105 has a second sleeve recess 365. The second sleeve recess 365 is arranged circumferentially, for example, spaced apart from the marking 340.

[0102] The second sleeve recess 365 can, for example, be identical to the first sleeve recess 345, such that the second sleeve recess 365 is formed tangentially to the axis 35 in the crimp sleeve 105. The second sleeve recess 365 can be arranged opposite the first sleeve recess 345.

[0103] The first sleeve recess 345 and the second sleeve recess 365 are of the same length in the axial direction and are spaced at identical distances from the first sleeve end 320 and the second sleeve end 325.

[0104] Furthermore, it is advantageous if the first sleeve recess 345 and the second sleeve recess 365 are longer in the axial direction with respect to the axis 35, for example, than the marking 340.

[0105] Fig. Figure 12 shows a longitudinal section through the Fig. 10 and Fig. 11 shown crimp sleeve 105 along the axis 35, wherein in Fig. 12. Hatching of the cut surfaces of the crimp sleeve 105 is omitted as an example.

[0106] The crimp sleeve 105 has a first sleeve opening 355 at the first sleeve end 320, wherein the first sleeve opening 355 has a first cross-sectional area. At the second sleeve end 325, the crimp sleeve 105 has a second sleeve opening 360, wherein the second sleeve opening 360 has a second cross-sectional area that is smaller than the first cross-sectional area.

[0107] On an inner circumferential side 385 of the sleeve, the crimp sleeve 105 has a flare 390 that adjoins the first sleeve end 320. In the axial direction, on the side facing away from the first sleeve end 320, a sleeve contact surface 395 adjoins the flare 390 on the inner circumferential side 385 of the sleeve. This contact surface is essentially cylindrical and extends around the axis 35. The flare 390 is wider in the radial direction than the sleeve contact surface 395. Axially adjacent to the sleeve contact surface 395, the crimp sleeve 105 tapers towards the second sleeve end 325.

[0108] Fig. Figure 13 shows a sectional view along a [unclear] in Fig. Section BB through the crimp sleeve 105 shown in section 10, wherein in Fig. 13. Hatching of the cut surfaces of the crimp sleeve 105 is omitted as an example.

[0109] At the marking 340, radially opposite on the inner circumferential side 385 of the sleeve, the crimp sleeve 105 has a bulge 400, which is formed essentially corresponding to the geometric shape of the marking 340. The marking 340 is designed in the crimp sleeve 105 such that the wall thickness in the area of ​​the marking 340 is essentially constant compared to the areas adjoining the marking 340 in the circumferential direction. The bulge 400 projects into the interior of the sleeve 330 and extends radially beyond the remaining inner circumferential side 385 of the sleeve.

[0110] Furthermore, the first sleeve recess 345 and the second sleeve recess 365 are, by way of example, essentially planar at the respective sleeve recess base and aligned parallel to each other.

[0111] Fig. Figure 14 shows a perspective view of the throw-over element 95 of the in Fig. 1 shown contact device 20.

[0112] The locking element 95 extends essentially along the axis 35 and is hollow. The locking element 95 extends between a first locking end 405 and a second locking end 410. The first locking end 405 faces away from the umbrella sleeve 100 and the crimp sleeve 105, while the second locking end 410 faces both the umbrella sleeve 100 and the crimp sleeve 105.

[0113] The coupling element 95 can have an external thread 415 axially adjoining the first coupling end 405 with respect to the axis 35, which is designed, for example, for mechanical contacting and connecting the contact device 20 with the mating contact device 30. Additionally, a profile section 420 can be connected axially to the outside of the external thread 415 to introduce a torque into the coupling element 95 in order to screw the external thread 415 into the mating contact device 30.

[0114] Fig. Figure 15 shows a longitudinal section along axis 35 through the in Fig. 15 shown throw element 95, wherein in Fig. 15. For example, hatching of the cut surfaces of the throw-over element 95 is omitted.

[0115] The locking element 95 has a second locking groove 430 on an inner circumferential side 425, which extends radially outwards. The second locking groove 430 can, for example, be arranged axially offset from the external thread 415. The second locking groove 430 is preferably formed circumferentially with respect to the axis 35.

[0116] Fig. 16A and Fig. Figure 16B shows a perspective view of the contact carrier 115 and the contact element arrangement 120 from different viewpoints.

[0117] The contact carrier 115 has an associated contact receptacle 450 for each of the contact elements 150, 155, wherein the first contact element 150 or the second contact element 155 engages in the contact receptacle 450 on the reverse side on a side facing away from a contact section 440 of the contact element 150, 155.

[0118] In this embodiment, for example, the contact section 440 is configured as a plug-in contact. A design as a socket contact is also possible for the contact section 440. The contact receptacle 450 orients the first contact element 150 and the second contact element 155 and holds them securely in their position relative to each other.

[0119] The contact carrier 115 has a substantially cylindrical basic shape, wherein, for example, on the side facing away from the contact section 440, the contact carrier 115 has at least one second coding lug 455. Preferably, two second coding lugs 455 are arranged opposite each other on the contact carrier 115 and extend radially outwards. On the axial side facing the second coding lug 455, for example, the individual cable 70 can be encoded – shown in dashed lines in Fig. 16B - be inserted into the associated contact receptacle 450, wherein in the contact receptacle 450 a corresponding electrical conductor of the respective single cable 70 is connected both electrically and mechanically to the associated first or second contact element 150, 155.

[0120] In a further training course that was held in the Fig. 16A and Fig. In the embodiment of the contact carrier 115 shown in 16B, the contact indexing carrier can be extended, in particular along the axis 35.

[0121] Fig. Figure 17 shows a perspective view of the optional insert 125.

[0122] The insert 125 is exemplarily designed in two parts and comprises a first insert element 460 and a second insert element 465, which are shaped like hemispheres. Both the first insert element 460 and the second insert element 465 together enclose an insert interior 470 and are essentially hollow bodies. The first insert element 460 and the second insert element 465 can interlock and be positively connected to each other, for example, by means of a snap-fit ​​connection. It is also possible for the insert 125 to be designed as a single piece.

[0123] On its radial outer surface, the insert 125 has a third coding lug 475. Preferably, two opposing third coding lugs 475 are arranged on the insert 125, wherein the third coding lug 475 is shaped circumferentially, for example, identically to the second coding lug 455 of the contact carrier 115. Alternatively, the third coding lug 475 can be shaped circumferentially identically to the first coding lug 160 on the insulating body 110.

[0124] Furthermore, the insert 125 has a second recess 480, which is slot-shaped and, in the assembled state, is located on the side facing the contact element arrangement 120. The second recess 480 is open at its end face.

[0125] Furthermore, it is possible that in a further development of the embodiment shown, the insert 125 and the insulating body 110 are formed in one piece and of a single material.

[0126] Fig. Figure 18 shows a perspective view of the partially assembled contact device 20.

[0127] This is in Fig. The insulating body 110, the contact element arrangement 120, the contact carrier 115, and the insert 125 are arranged axially relative to one another with respect to the axis 35. The first coding lug 160, the second coding lug 455, and the third coding lug 475 are arranged axially one behind the other in alignment. Preferably, the first coding lug 160, the second coding lug 455, and the third coding lug 475, which are arranged opposite each other, are arranged in a common plane in which the axis 35 is also located.

[0128] Fig. Figure 19 shows a longitudinal section through the in Fig. 19 partially assembled contact device 20 shown, wherein in Fig. 19. Hatching of the cut surfaces is omitted as an example.

[0129] In its partially assembled state, the contact carrier 115 engages in the carrier receiving space 187, preferably bearing against the first receiving base 205 at its end face. On the side facing away from the insulating body 110, in the axial direction with respect to the axis 35, the insert 125 and the contact carrier 115 engage with each other, so that they are arranged relative to each other in a defined circumferential direction. The insert 125 can bear against the end face of the contact carrier 115 on the side facing away from the insulating body 110, and the first coding lugs 160, the second coding lugs 455, and the third coding lugs 475 are arranged axially directly one behind the other.

[0130] The second coding nose 455 engages not only in the first recess 185 in the axial direction, but also in the second recess 480 in the radial direction, so that in the circumferential direction the insulating body 110, the contact carrier 115 and the insert 125 are defined relative to each other. Fig. Figure 20 shows a perspective view of the contact device 20 in a partially assembled state.

[0131] Opposite Fig. 19 is in Fig. Figure 20 additionally shows the shielding sleeve 100. In the partially assembled state, the first coding lug 160 of the insulating body 110, the second coding lug 455 of the contact carrier 115, and the third coding lug 475 of the insert 125 engage in the coding receptacle 310 of the shielding sleeve 100, so that the insulating body 110, the contact carrier 115, and the insert 125 are also aligned relative to each other in a defined circumferential direction with respect to the axis 35. In particular, the respective engagement causes the coding lugs 160, 455, and 475 to be offset circumferentially with respect to the axis 35 relative to the receiving groove 275.

[0132] Fig. Figure 21 shows a longitudinal section through the electrical cable 10, where in Fig. 21. For example, hatching of the cut surfaces is omitted.

[0133] In Fig. 21 the electrical cable 10 is fully assembled and can be used, for example, to connect the mating contact device 30 (in Fig. 21 not shown and in Fig. 1 indicated). Furthermore, the shield cable 25 is only partially connected to the contact device 20 in Fig. 21 shown.

[0134] In a first section adjoining one cable end of the shielded cable 25, both the outer cable insulation 45 and the inner cable insulation 55 are removed from the shielded cable 25, so that the individual cables 70 and the shield conductor 50 are guided parallel to the axis 35. Furthermore, the shield conductor 50 is arranged radially on the outside. A second section of the shielded cable 25 adjoins the first section, in which the shielded cable 25 has its complete structure (as shown in Fig. 1 described) and in particular the outer cable insulation 45 and / or the inner cable insulation 55 are not removed.

[0135] In the assembled state, the shield cable 25 is inserted at the second sleeve end 325 via the second sleeve opening 360 into the sleeve interior 330 with the second subsection, so that the first subsection, in which, as just described, the inner and outer cable insulation 45, 55 are removed, is completely arranged within the contact device 20, in particular within the sleeve interior 330.

[0136] On the outer side, the shielding cable 25 is axially enclosed by the third sealing element 145 adjacent to the second sleeve opening 360 on the cable's outer side 40. The third sealing element 145 bears radially against the sleeve contact surface 395 of the inner sleeve circumferential side 385, thereby sealing the shielding cable 25 fluid-tight against the environment 60 at the second sleeve opening 360. This prevents gas and / or liquid from entering the sleeve interior 330 from the environment 60 at the second sleeve opening 360.

[0137] Axially opposite the crimp sleeve 105, the shield sleeve 100 engages the coupling element 95 with its first engagement section 220. The coupling element 95 is rotatable relative to the shield sleeve 100 in the axial direction with respect to the axis 35. This rotatability is ensured by the engagement of a locking element 435 in the first locking groove 255 and the second locking groove 430. The locking element 435 can, for example, be designed as a retaining ring.

[0138] Additionally, secure support and rotation of the locking element 95 in the axial direction towards the shield sleeve 100 are ensured by the fact that the locking element 95 rests against the first contact surface 230 on the side facing the shield sleeve 100. At the same time, an assembly force acting in the axial direction along the axis 35 towards the crimp sleeve 105 can be reliably supported by the locking element 95 resting against the first contact surface 230.

[0139] The contact element arrangement 120 is, for example, arranged in the insulating body 110 such that, on the side facing away from the crimp sleeve 105, each of the contact elements 150, 155 projects beyond the insulating body 110 with a contact section 440. The contact element arrangement 120 is positioned relative to the insulating body 110 and to the retaining element 95 such that a tip 445 of the first contact element 150 and / or a tip 445 of the second contact element 155 is set back from the first retaining end 405. This ensures that the contact section 440 is protected from unintentional mechanical contact, in particular from stress on the contact section 440 in the bending direction, for example, by lateral pressure on the contact section 440, and thus prevents unintentional mechanical damage to the contact section 440.

[0140] The first contact element 150 and / or the second contact element 155 is fluid-tightly inserted into the insulating body 110 and is additionally mechanically supported on the side facing away from the contact section 440 by the contact carrier 115. Furthermore, the first contact element 150 and the second contact element 155 are each electrically connected to the associated single cable 70 on the side facing away from the contact section 440.

[0141] In addition to the overlock element 95, the insulating body 110 also partially engages in the shield sleeve 100, wherein the insulating body 110 is arranged radially inside the first engagement section 220, the shoulder 225 and the crimping section 240.

[0142] On the inside, the contact carrier 115 engages in the carrier receiving space 187 in the insulating body 110 and is inserted up to the first receiving base 205 in the direction of the overlocking element 95.

[0143] Fig. 22 shows one in Fig. 21 marked section E of the in Fig. 21 electrical cables shown 10.

[0144] The second sealing element 135 is inserted radially on the outside in the first groove 170 in order to seal the inner space 330 of the sleeve against the environment 60 on the insulating body 110.

[0145] The spring section 245 is in its fully assembled state compared to the one in Fig. The individual component of the shielding sleeve 100 shown in Figure 9 is tensioned and pressed radially inwards towards the axis 35. The spring section 245 provides a clamping force FS that acts radially outwards. The shielding conductor 50 is arranged radially between the spring section 245 and the sleeve contact surface 395, and the shielding conductor 50 may be expanded relative to the second section of the shielding cable 25. The shielding conductor 50 rests radially against the inner side of the spring section 245. Due to the clamping force FS, the spring section 245 presses the shielding conductor 50 radially outwards and presses it against the sleeve contact surface 395, so that the shielding conductor 50 is electrically connected to both the crimping sleeve 105 and the spring section 245 of the shielding sleeve 100.

[0146] In the fully assembled state, the first sleeve end 320 rests against the end face of the second contact surface 235 of the shoulder 225 of the shield sleeve 100, so that the position of the crimp sleeve 105 relative to the shield sleeve 100 is defined in the axial direction.

[0147] The expansion 390 is arranged radially outside the sealing groove 260, with the first sealing element 140 of the sealing element arrangement 130 being arranged in the sealing groove 260. The first sealing element 140 seals the interior of the sleeve 330 against the shielding sleeve 100 from the surrounding environment 60. Due to the second sealing element 135 being arranged radially inside the first groove 170 of the insulating body 110, replacement of the second sealing element 135 is unnecessary, as it cannot be damaged during the separation of the crimp sleeve 105.

[0148] Axially between the spring section 245 and the sealing groove 260, the crimp sleeve 105 is crimped onto the crimp section 240 of the shielding sleeve 100 in the area of ​​the crimp section 240, so that the sleeve contact surface 395 is positively connected to the shielding sleeve 100 at the crimp section 240. This positive connection prevents the crimp sleeve 105 from being unintentionally pulled off the shielding sleeve 100. Furthermore, the metallic design of the crimp sleeve 105 and the positive connection with the shielding sleeve 100 ensure that manipulation and unintentional reversible loosening of the crimp sleeve 105 from the shielding sleeve 100 are avoided and preferably prevented.

[0149] In particular, this ensures that security-relevant data communication between individual participants in automation system 10 is not disrupted by unintentional and unauthorized manipulation of the contact device 20. This avoids time-consuming troubleshooting within automation system 10.

[0150] Furthermore, the sealed design of the electrical cable 10 ensures that it can be used particularly in corrosive environments or in potentially explosive atmospheres (EX areas).

[0151] Fig. 23 shows a sectional view along a Fig. Section FF shown in section 22 through the electrical cable 10, wherein in Fig. 23. For example, hatching of the cut surfaces is omitted.

[0152] In the circumferential direction, for example, the crimp sleeve 105 is aligned with the shield sleeve 100 such that the marking 340, which is arranged on the outside of the crimp sleeve 105, engages with the recess 400 arranged on the inside of the crimp sleeve 105 in the receiving groove 275 and thereby, in addition to the force-fit connection between the sleeve contact surface 395 and the crimping surface 270, the crimp sleeve 105 is connected to the shield sleeve 100 in a torque-resistant manner.

[0153] In its assembled state, the sleeve contact surface 395 and the receiving groove 275 form a tool receiving chamber 485. The orientation of the tool receiving chamber 485, both axially and circumferentially with respect to the axis 35, is indicated externally by the marking 340 and is thus defined in both the circumferential and axial directions with respect to the axis 35. The marking 340 therefore indicates the orientation of the receiving groove 275 on the outside of the press-fit sleeve 105.

[0154] The tool mounting space 485 and the mounting groove 275 can be extended circumferentially along the axis 35 to the coding lugs 160, 455, 475 (clearly shown in the Fig. 19 and Fig. 20 recognizable) offset and thus non-aligned. An aligned arrangement in the axial direction is understood to mean that when at least two components (for example, the first coding nose 160 and the tool holding space 485 and / or the holding groove 275) are projected parallel to the axis 35 into a projection plane that is perpendicular to the axis 35, the two components overlap in the projection plane.

[0155] Fig. Figure 24 shows a perspective view of a dismantling device 600 according to a first embodiment.

[0156] The disassembly device 600 comprises a cutting tool 605 and a carrier 610. The cutting tool 605 and the carrier 610 are movable relative to each other along the axis 35. In this embodiment, the cutting tool 605 has, for example, a saw blade 615, wherein the saw blade 615 is arranged in a cutting plane 630, in which the axis 35 also runs. The saw blade 615 is driven. Additionally, the cutting tool 605 can be moved away from and towards the cable 10 in a radial direction with respect to the axis 35.

[0157] The carrier 610 has a carrier receptacle 625, wherein at least the contact device 20 can be mechanically fixed in the carrier receptacle 625.

[0158] In particular, the disassembly device 600 serves to weaken the shield sleeve 105 so that the contact device 20 can be separated from the shield cable 25 and, if necessary, replaced by a repaired or a new contact device 20 of the same type (this can be the same or a different contact device 20). The disassembly procedure described below is used for this purpose.

[0159] Fig. 25 shows a flowchart of a procedure for repairing the [unclear] in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23 to Fig. 24 electrical cable shown 10. The individual steps of the in Fig. The flowchart shown in 25 is described in connection with the following figures.

[0160] Fig. Figure 26 shows a section of a perspective view of the in Fig. 24 Disassembly device 600 shown according to a first embodiment during a second process step 510 of the repair process of the in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22 to Fig. 23 electrical cables shown 10. Fig. 27 shows a sectional view along a Fig. 24 shown section plane GG through the in Fig. 26 Disassembly device 600 shown with inserted electrical cable 10 during the second process step 510, wherein in Fig. 27. For example, hatching of the cut surfaces is omitted.

[0161] In a first procedural step 505 (see Fig. 24) The contact device 20, in its assembled state, is inserted and positioned in the carrier receptacle 625 on the shield cable 25 such that the tool receptacle 485, and thus also the receptacle groove 275, is arranged in the parting plane 630 with the cutting tool 605, and the tool receptacle 485 faces the cutting tool 605. The axis 35 can also run in the parting plane 630.

[0162] The alignment of the contact device 20 can be determined, for example, by means of the first sleeve recess 345 and / or the second sleeve recess 365 (in Fig. 24 (covered). The marking 340 (see also) can also be used. Fig. 10) can be used for aligning the contact device 20 or taken into account when aligning the contact device 20. For example, the receiving groove 275 can be arranged inside the crimping sleeve 105 to optimally align the contact device 20 relative to the separating tool 605 in the first process step 510.

[0163] Alternatively, the contact device 20 can be configured by the defined alignment of the contact elements 150, 155 ( Fig. 21) via the contact carrier 115 and the second coding nose 455 (see Fig. 18) are defined on the crimp sleeve 105 by means of the contact element arrangement 120 and aligned to the carrier 610.

[0164] In the second process step 510, the separating tool 605 is activated and driven (see Fig. 26) to selectively weaken the crimp sleeve 105 during crimping and to selectively separate it. The separating tool 605, by means of a defined orientation relative to the contact device 20, cuts through the crimp sleeve 105 at the crimping surface 270 and penetrates the tool receiving chamber 485 from radially outside to radially inside during the separating process. In doing so, the separating tool 605 creates a separating slot 635 in the crimp sleeve 105 extending radially in the direction and along the axis 35. The separating of the crimp sleeve 105 can be carried out independently of the direction along the axis 35.

[0165] The carrier 610 and the cutting tool 605 are preferably moved relative to each other such that the cutting slot 635 extends substantially completely along the axis 35 over the tool receiving space 485 and the pressing section 240 of the shield sleeve 100 and opens radially into the tool receiving space 485 (cf. Fig. 27). The separating slot 635 is thus a slot-shaped through-opening in the previously closed crimp sleeve 105.

[0166] Through the separating slot 635 (see Fig. 27) The crimp sleeve 105 is selectively weakened at the crimping section 240, so that the crimping of the crimp sleeve 105 at the crimping section 240 is reduced, preferably eliminated. The crimp sleeve 105 may widen slightly at the separating slot 635 after being separated.

[0167] In addition, the saw blade 615 is selected with regard to its outer diameter in such a way that sawing into the shoulder 225 and into the profile section 420 of the collating element 95 is avoided during the cutting of the crimp sleeve 105.

[0168] Furthermore, opposite paragraph 225 of the shield sleeve 100, it is avoided that the cutting tool 605 engages in one of the coding lugs 160, 455, 475, in particular the first coding lug 160 located closest to the receiving groove 275.

[0169] In the radial direction, the cutting tool 605 is only inserted into the press-fit sleeve 105 to such an extent that the cutting tool 605 is spaced apart from the groove base 305 of the receiving groove 275, and plunging and thus chip removal on the press-fit sleeve 105 is avoided.

[0170] Furthermore, the preferably wider design of the receiving groove 275 compared to the thickness of the saw blade 615 prevents contact between the saw blade 615 and at least one of the two groove side surfaces 281, 285 due to the defined orientation of the contact device 20 to the cutting tool 605. This prevents damage to the shield sleeve 100.

[0171] Furthermore, it is noted that penetration and thus damage / destruction of the first sealing element 140 by the separating tool 605 is possible and permissible, whereby damage is preferably avoided by a suitable selection of the separating tool 605 and the travel path along the axis 35 in the direction of the shoulder 225. In particular, immersion of the separating tool 605 into the sealing groove 260 is avoided.

[0172] In a third process step 515, which follows the second process step 510, the separating tool 605 is removed from the contact device 20 and the electrical cable 10 is removed from the disassembly device 600.

[0173] In a fourth process step 520 following the third process step 515, the weakened crimp sleeve 105 is pulled off the other components, in particular the shielding sleeve 100 and the contact carrier 115, along the axis 35. The retaining element 95 can remain on the shielding sleeve 100. For this purpose, a tool can, for example, be applied to the first and / or second sleeve recess 345, 365, and a pulling force acting away from the retaining element 95 along the axis 35 can be applied to the crimp sleeve 105. Additionally, the crimp sleeve 105 can be rotated around the axis 35 via the first and / or second sleeve recess 345, 365 with a circumferentially alternating torque to enable the crimp sleeve 105 to be pulled off the other components of the contact assembly 20.

[0174] In a fifth process step 525 following the fourth process step 520, the further components, in particular the contact carrier 115, together with the insulating body 110 and the contact element arrangement 120, can be pulled out of the sleeve interior 330 along the axis 35.

[0175] It is also possible that in the fifth process step 525 the individual components of the contact device 20 are disassembled according to their material composition in order to improve the recycling of the contact device 20 and the shield cable 25.

[0176] If necessary, the contact device 20 will be further repaired following the first to fifth steps 505 to 525.

[0177] The crimp sleeve 105, which was slit open and provided with the separation slot 635 in the second process step 510, is recycled. Any damaged first sealing element 140 is replaced, ensuring a reliable seal between the contact device 20 and the environment after assembly of the contact device 20 and the shield cable 25 to the electrical cable 10, even after repair of the electrical cable 10.

[0178] By slitting the crimp sleeve 105 and immersing the separating tool 605 in the receiving groove 275, unintentional damage to the shield sleeve 100 and the other insulating elements 110, contact carrier 115 and insert 125 arranged inside the shield sleeve 100 is prevented. This allows the contact assembly 20 to be disassembled and reassembled cost-effectively and almost reversibly without damage (with the exception of the crimp sleeve 105).

[0179] In a sixth process step 530, the contact device 20 is reassembled using a new, additional crimp sleeve 105. This additional crimp sleeve 105 is identical to the original crimp sleeve 105. Furthermore, the additional crimp sleeve 105 is continuous in the circumferential direction and without a separating slot 635.

[0180] During the reassembly of the contact device 20 of the electrical cable 10, the new crimp sleeve 105 can be pushed onto the shield sleeve 100 along the axis 35 until the first sleeve end 320 abuts the second contact surface 235. Furthermore, in the sixth process step 530, the additional crimp sleeve 105 is aligned circumferentially, for example, based on the first and / or second sleeve recess 345, 365.

[0181] Then, in a seventh process step 535, the crimp sleeve 105 can be crimped onto the shield sleeve 100 in the crimping section 240.

[0182] Furthermore, the (newly) crimped crimp sleeve 105 prevents unintentional manipulation of the contact device 20, thus ensuring that transmission errors, particularly within the automation system 15, which may be caused by a defective electrical cable 10, cannot be caused by a manipulated contact device 20. This avoids lengthy troubleshooting, especially in the automation system 15.

[0183] Furthermore, it is possible that the in Fig. The disassembly procedure described in section 25 is carried out on-site on the electrical cable 10 laid in the automation system 15, thus eliminating the need to re-lay the shield cable 25 within the automation system 15. This can significantly reduce repair time, especially for long shield cables 25.

[0184] Fig. Figure 28 shows a disassembly device 600 according to a second embodiment.

[0185] The dismantling device 600 is essentially identical to the one in the Fig. 24, Fig. 26 and Fig. Dismantling device 600 shown in 27. The following refers exclusively to the differences of the Fig. Disassembly device 600 shown in 28 according to the second embodiment compared to the one shown in the Fig. 24, Fig. 26 and Fig. 27 Disassembly device 600 shown according to the first embodiment.

[0186] In contrast, in Fig. 28 The cutting tool 605 is designed not as a saw blade 615, but as a milling cutter 640. The milling cutter 640 preferably has a maximum milling width b equal to the maximum width of the mounting groove 275. This ensures that when the cutting slot 635 is inserted into the crimp sleeve 105, the shield sleeve 100 is not damaged, even in the area of ​​the mounting groove 275.

[0187] With the in Fig. The dismantling device 600 shown in 28 can also be used in Fig. The disassembly procedures described in section 25 are carried out, with the exception that in the second process step 510 the press-fit sleeve 105 is not sawn open, but milled open. The separation slot 635 is also made along the axis 35 into the press-fit sleeve 105.

[0188] Fig. Figure 29 shows a longitudinal section through the electrical cable 10 according to the second embodiment, wherein in Fig. 29. For example, hatching of the cut surfaces is omitted.

[0189] The electrical cable 10 is essentially identical to the one in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24, Fig. 25, Fig. 26, Fig. 27 to Fig. 28 explained electrical cables 10 formed, but in the following only the differences of the in Fig. Cable 10 shown in 29 according to the second embodiment compared to the one shown in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24, Fig. 25, Fig. 26, Fig. 27 to Fig. 28. Electrical cables 10, as described in the first embodiment, are discussed. In particular, the cable described in Fig. 29 electrical cables 10 the contact device 20 shown in parts opposite the one in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24, Fig. 25, Fig. 26, Fig. 27 to Fig. 28 explained contact device 20 modified, while the shield cable 25 is identical to the one described in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24, Fig. 25, Fig. 26, Fig. 27 to Fig. The first embodiment of the electrical cable 10 is described in Figure 28. The changes are discussed in the following figures.

[0190] Fig. Figure 30 shows a perspective view of the umbrella sleeve 100 of the in Fig. 29 shown electrical cable 10 according to the second embodiment.

[0191] In particular, the contact device 20 of the electrical cable 10 according to the first embodiment and the contact device 20 of the electrical cable 10 according to the second embodiment are essentially identical. This also applies to the Fig. 31 shown umbrella sleeve. In contrast, the receiving groove 275 is different from the one shown in particular in Fig. In the embodiment shown in 9, the umbrella sleeve 100 is arranged offset in the circumferential direction with respect to the axis 35. Fig. 30, the receiving groove 275 is formed, for example, flush with the second spring gap 301 and the coding receptacle 310 in the contact surface 270. The receiving groove 275 can have the maximum width b, which is shown in Fig. 30, for example, is narrower than the second gap width of the second spring gap 310.

[0192] Due to the identical circumferential width of the second spring gap 301 and the coding receptacle 310, the receiving groove 275 is also narrower in the circumferential direction than the coding receptacle 310 which ends at the receiving groove 275.

[0193] In Fig. 30 is in the axial direction with respect to axis 35 compared to the one in Fig. In the first embodiment of the electrical cable 10 shown in 9, the receiving groove 275 is shortened. For example, it extends into Fig. 30 the receiving groove 275 in axial direction between the second groove 265 and the sealing groove 260, wherein the second groove 265 and the coding receptacle 310, for example, meet one another. Furthermore, in Fig. 30 the pressure surface 270 is formed in a ring shape by the receiving groove 275.

[0194] It is pointed out that in a further training course of the in Fig. 30 and Fig. In the different embodiments of the electrical cable 10 shown in Figure 9, with their respective different configurations of the shield sleeve 100, it would also be possible for the receiving groove 275 to be arranged circumferentially between the first spring gap 300 and the second spring gap 301, and thus also circumferentially between the second spring gap 301 and the coding receptacle 310. It is advantageous if the receiving groove, as shown in Figure 9, is arranged in the same way as the first spring gap 300 and the second spring gap 301. Fig. Figure 9 shows that it extends in the axial direction at least between the sealing groove 260 and the transition 266. This further development is described in Figure 9. Fig. 30 indicated by dashed lines.

[0195] Fig. Figure 31 shows a longitudinal section through the in Fig. 30 shown umbrella sleeve 100, wherein in Fig. 31. For example, hatching of the cut surfaces is omitted.

[0196] As already mentioned in the context of Fig. As explained in section 9, the coding receptacle 310 is also designed as a through-opening, so that the coding receptacle 310 opens into the interior of the shield sleeve 249.

[0197] The sealing groove 260 extends radially deeper from the contact surface 270 towards the interior of the shield sleeve 249 than the receiving groove 275. This ensures that damage to or destruction of the sealing groove 260 and the risk of damage to the first sealing element 140 are reduced when the separation slot 635 is introduced in the second process step 510. If the first sealing element 140 should nevertheless be damaged in the second process step 510, it can be replaced by a new first sealing element 140 during the subsequent disassembly or assembly process.

[0198] The in the Fig. 29 and Fig. The second embodiment of the electrical cable 10 shown in Figure 30 can be connected by means of the Fig. The repair procedure described in section 25 is used to disassemble the electrical cable 10 and subsequently reassemble it. The repair procedure can be carried out using the method described in section 25. Fig. 24 and Fig. Disassembly device 600 shown in 26 according to the first embodiment or by means of the Fig. The disassembly device 600 shown in 28 is separated according to the second embodiment. In doing so, the components within the scope of the Fig. The 25 explained procedural steps were also implemented.

[0199] In contrast to Fig. In the first process step 505, the cable 10 and thus also the shield sleeve 100 arranged in the contact device 20 are oriented differently, such that the receiving groove 275 is arranged in the parting plane 630 and preferably the parting plane 630 is positioned centrally between the first groove side surface 281 and the second groove side surface 285 in the circumferential direction with respect to the axis 35. Furthermore, the contact device 20 of the cable 10 is positioned in the carrier receptacle 625 in the circumferential direction such that the receiving groove 275 faces the cutting tool 605.

[0200] In the second process step 510, the crimp sleeve 105 is separated by the separating tool 605 in such a way that damage to the first sealing element 140 and to the first coding lug 160 engaging in the coding receptacle 310 is preferably avoided. For this purpose, the separating slot 635, which is introduced into the crimp sleeve 105 by the separating tool 605, is positioned opposite the one in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22 to Fig. The contact device 20 shown in 23 is shortened. However, this weakening is sufficient to reduce the pressure exerted on the crimping sleeve 105 on the crimping surface 270 so that the crimping sleeve 270 is not shortened in the fourth process step 520 (see 23). Fig. 25) can be withdrawn from the other components, in particular the shield sleeve 100 and the contact carrier 115, along the axis 35.

[0201] The umbrella sleeve 100 is oriented circumferentially in Fig. 29 compared to the one in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24, Fig. 25, Fig. 26, Fig. 27 to Fig. 28 shown embodiment, arranged offset. In particular, the crimp sleeve 105 with the marking 340 can be rotated such that the marking 340 is aligned in the circumferential direction at a defined angle, for example 90°, offset from the receiving groove 275.

[0202] Fig. 32 shows a sectional view along the in Fig. Section BB shown in 10 through the in Fig. 29 shown crimp sleeve 105, wherein in Fig. 32. Hatching of the cut surfaces is omitted as an example.

[0203] It is clear in Fig. 32. It is evident that the offset of marking 340 in the circumferential direction indicates that the marking in Fig. The bulge shown in 13 400 does not form, but rather the inner circumferential side of the sleeve 385 is essentially cylindrical on the inside.

[0204] This design has the advantage that the tool receiving space 187 formed by the receiving groove 275 and the inner sleeve circumferential side 385 is enlarged in the radial direction and, when the operation is carried out in Fig. In the repair procedure described in section 25, the separating tool 605 does not need to penetrate radially into the crimping sleeve 105 as far as it would in the procedure described in section 25. Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24, Fig. 25, Fig. 26, Fig. 27 to Fig.28 is necessary in the first embodiment shown. This also prevents damage to the shield sleeve 100 in the area of ​​the receiving groove 275, in particular in the area of ​​the first and / or second groove side surfaces 281, 285.

[0205] The invention is not limited to the embodiments described above and can be modified in various ways within the scope of the claims. For example, a straight contact device 20 is shown in the embodiments described. To facilitate accessibility, particularly in very confined automation systems, the contact device 20 is offered not only in a straight version but also in a version angled by 90°. Even with such an angled version of the contact device 20, the inventive design of the contact elements allows for particularly simple and space-saving connection of the electrical cable to the contact elements. 10 electrical cables 15 Automation system 20 Contact facility 25 shielded cables 30 Counter-contact device 35 axle 40 Cable outer side 45 Outer cable insulation (sheath insulation) 50 shield conductors 55 inner cable insulation 60 surroundings 65 Cable arrangement 70 individual cables 85 Contact page 90 cable side 95 Overthrow element 100 umbrella sleeves 105 Press-fit sleeve 109 Contact housing interior 110 insulating bodies 115 contact carriers 120 contact element arrangement 125 inserts 130 Sealing element arrangement 135 second sealing element 140 first sealing element 145 third sealing element 150 first contact element 155 second contact element 160 first coding nose 165 outer perimeter side 170 first groove 185 first exception 186 first insulating body end face 187 Carrier reception room 190 second insulating body end face 195 first insulating body section 200 second insulating body section 205 Reason for admission 206 first contact element recording 207 second contact element intake 210 first end of umbrella sleeve 215 second end of umbrella sleeve 220 first intervention phase Paragraph 225 230 first planting area 235 second planting area 240 Press-fit section 245 spring section 249 Umbrella tube interior 250 Umbrella sleeve circumference side 255 first locking groove 260 sealing groove 265 second groove 266 Transition 270 pressure surface 275 recordings 280 Shield contact spring arrangement 281 first groove side surface 282 second groove side surface 290 first shield contact spring 295 second shield contact spring 300 first spring gap 301 second spring gap 305 Groove 310 Coding recording 320 first case end 325 second end of case 330 Case interior 335 outer sleeve circumference side 340 Marking 345 first sleeve recess 355 first case opening 360 second sleeve opening 365 second sleeve recess 385 inner sleeve circumference side 390 widening 395 Sleeve contact area 396 first sleeve section 397 second sleeve section 400 bulge 405 first overthrow end 410 second overthrow end 415 External thread 420 Profile section 425 inner circumferential side (of the throw-over element) 430 second locking groove 435 Safety element 440 Contact section 445 Peak 450 contacts 455 second coding nose 460 first insert element 465 second insert element 470 insert interior 475 third coding nose 480 second recess 485 Tool storage area 505 first procedural step 510 second procedural step 515 third procedural step 520 fourth procedural step 525 fifth procedural step 530 sixth procedural step 535 seventh process step 600 Dismantling device 605 Cutting tool 610 carriers 615 saw blade 620 drive motor 625 Carrier attachment 630 Separation plane 635 Separating slot 640 milling cutters b Maximum width FS clamping force
