Description

Technical Field

[0001] The present invention relates to a fixing device for securing cables having braided layers, particularly shielding braided layers. Background Technology

[0002] This type of fixing device serves two purposes: relieving cable tension and providing electromagnetic shielding and dissipating interference in the circuit. To this end, the cable is axially fixed and makes electrical contact with the cable braid layer located beneath the cable's outer sheath (insulation layer). Various fixing devices are known in the prior art. Current fixing devices typically include a sleeve-shaped base element disposed on the cable, a clamping element for securing the cable, and a tensioning element that can be connected to the base element and positions the clamping element on the base element. According to this application, a contact element for making electrical contact with the cable braid layer may also be included.

[0003] One example is DE19523795, which illustrates a cable conduit for a shielded switch cable. This cable conduit includes a grounded clamping sleeve that surrounds and engages the exposed shielding sheath to provide contact. The cable conduit also has a compression sleeve, which is divided into a thin-walled compression portion and a thick-walled support portion. The compression sleeve is pushed onto the unstripped end of the switch cable by means of its compression portion and is crimped to said end. The exposed shielding sheath is then folded back onto the support portion, and the clamping sleeve is pushed onto the support portion with the shielding sheath by means of its clamping portion and is also crimped to the support portion by (radial) crimping.

[0004] DE102013201531 illustrates an electrical contact connection structure between the shielding layer and the outer casing wall of a shielded wire. The shielded wire is surrounded by a contact sleeve, which makes electrical contact with both the shielding layer and the outer casing wall. The contact sleeve is pressed against the outer sheath of the shielded wire.

[0005] Inadequate electrical contact is frequently encountered in known securing devices for cables with braided shielding layers. This results in poor shielding quality and high shielding loss. For example, insufficient electrical contact can occur when the braided layer is over- or under-compressed. Therefore, to achieve good shielding quality, not only is it necessary to use shielded wire with maximum shielding performance, but also to use securing devices with good electromagnetic compatibility. The contact mechanism of the shielding layer must be designed to be mechanically stable in addition to meeting electrical requirements. Summary of the Invention

[0006] The purpose of this invention is to provide a fixing device with an improved cable braided layer connection.

[0007] The fixing device according to the invention is intended for cables having at least a partial outer braided layer. The cable includes at least one conductor and a cable sheath protecting the braided layer. However, the cable sheath is preferably partially removed in the assembly area of ​​the cable where the fixing device is to be connected, thus leaving the braided layer on the outside. According to an embodiment, the cable may be a shielded cable. The braided layer may be a shielding braided layer of the cable. Alternatively or additionally, the braided layer may be used for grounding. In addition to the braided layer, according to an embodiment, the cable may also have a film / foil, particularly a shielding film / foil (e.g., metal foil and / or metallized plastic film or the like) above or below the braided layer.

[0008] The fastening device according to the invention comprises a base element, a tensioning element interconnected with the base element, and a crimping element. The crimping element is particularly used to secure and contact the braided layer to the crimping element by crimping. Axial crimping is particularly advantageous. The securing of the cable or braided layer to the crimping element is preferably non-releasable, thus achieving a reliable and durable connection. When the braided layer is used as a shielding layer, this connection ensures durable, high-quality electrical contact. Axial crimping ensures symmetrical compression, with forces evenly distributed across the braided layer. This results in a generally smooth connection with low shielding loss. Furthermore, unlike radial compression, the effects on tolerance, such as those caused by the braided layer not being evenly stretched, are reduced in the case of axial compression. In addition to its effect on shielding layer contact, axial crimping also has a positive effect on the insulation performance of the cable, as it minimizes negative stresses such as cable insulation shrinkage.

[0009] A first opening for the cable to pass through extends axially through the base element. Additionally, the base element advantageously includes a base for supporting and mounting the base element onto a housing. The support surface of the base is advantageously configured such that it at least partially supports the housing. The base element may be made of a conductive material and / or have a conductive coating. In one possible embodiment, the base element has a first operable connection for operablely connecting the base element to, for example, the housing. The fixing device may have threads as the first operable connection. However, other operable connection types are also conceivable. Furthermore, the base element may have another (second) operable connection, such as threads, for interconnection with a tensioning element.

[0010] The tensioning element has a second opening extending in the axial direction for the passage of a cable. This opening is advantageously arranged coaxially with the first opening. In one possible embodiment, the base element has a third operable connection for operably connecting the tensioning element to the second operable connection of the base element. In one possible embodiment, the tensioning element is a clamping nut that can be screwed onto the base element. As described in more detail below, the tensioning element can be used to secure a crimping element disposed between the base element and the tensioning element, and optionally secure a clamping element.

[0011] Clamping elements can be used to additionally secure and clamp cables in a fixing device. According to this application, clamping elements can also be used to seal cables to the fixing device. In the assembled state, the clamping element can be positioned axially between the base element and the tensioning element. The clamping element can be designed as one or more parts. According to an embodiment, the clamping element, particularly in the axial direction, can have, for example, at least one groove. The groove can be designed to be corrugated. The advantage of a corrugated groove is that the clamping element for laterally inserting a cable can be opened (or spread out), but the clamping element will not loosen in the assembled state. The clamping element is advantageously made of a deformable material, particularly a ductile material. The clamping element is advantageously designed to be particularly radially deformable and / or radially resilient. This can be caused by the properties of the material and / or achieved by the shaping of the clamping element; thus, the clamping element can, for example, have at least one groove. The at least one groove can be oriented in the radial or axial direction. Similarly, the at least one groove can be designed to be continuous in the radial and / or axial directions, such that annular clamping elements are, for example, given a C-shape. When clamping elements are present, crimping elements are specifically used for electrical contact with the braided layer, while clamping elements are used to secure the cable, absorb tension, and optionally seal the cable to the fixing device. In this way, the braided layer is not subjected to excessive stress, and the electrical contact of the cable is separated from the cable fixing.

[0012] In a preferred embodiment, the fixing device may have an anti-torsion device. The anti-torsion device can be used to prevent rotation of the base element relative to the clamping element. For this purpose, the anti-torsion device may include at least one first fixing element disposed on the clamping element and at least one second fixing element disposed on the base element. In the assembled state, these fixing elements are at least partially engaged with each other, positioning the clamping element in the base element circumferentially. The at least one first fixing element may be disposed on the outer shell surface of the clamping element. The outer shell surface faces away from (outwards) the opening through which the cable passes in the axial direction of the clamping element. The at least one second fixing element may further be disposed on the inner shell surface of the base element. The inner shell surface of the base element faces the direction of the first opening through which the cable passes. The at least one first fixing element may be embodied in the form of a groove, while the at least one second fixing element may be a shaped element (or vice versa) at least partially engaged with each other in the groove in the assembled state. A plurality of (first and second) fixing elements are advantageously arranged to surround the respective shell surfaces, particularly at uniform intervals. For example, the anti-torsion device or the first and / or second fixing elements may be implemented as teeth and / or knurled, respectively. Knurling can represent stamping or milling features on the corresponding shell surface. Knurling is usually produced by a knurling process.

[0013] In its assembled state, the crimping element can be positioned between the base element and the tensioning element, or between the base element and the clamping element. By tensioning the tensioning element, the clamping element can be tensioned and positioned on the crimping element, and the crimping element can be tensioned and positioned on the base element. The crimping element advantageously comprises multiple parts, particularly two parts. For example, the crimping element may include an outer crimping sleeve and an inner support sleeve disposed within the outer crimping sleeve. In the assembled state of the cable in its fixing device, the (exposed) braided layer is disposed between the crimping sleeve and the support sleeve. The crimping sleeve can be crimped onto the inner support sleeve, particularly axially, such that the braided layer is fixed between the crimping sleeve and the support sleeve.

[0014] For crimping, the crimping sleeve preferably has a crimping region. The crimping region can extend axially. For good deformability, the crimping region is advantageously designed to be thin-walled. The crimping region can protrude from the base of the crimping sleeve, which has a thicker wall. The crimping sleeve can have a receiving space for accommodating a support sleeve. To position the support sleeve within the crimping sleeve, the crimping sleeve may alternatively or additionally include a stop for the support sleeve on its inner side along the axial direction. Thus, the crimping sleeve can be pushed axially from one side onto the support sleeve until the support sleeve enters the receiving space and abuts against the stop. In the assembled state, with the support sleeve in either the crimping sleeve or the receiving space, and in the (not yet) deformed state of the crimping region, the crimping region advantageously protrudes axially from the support sleeve. Thus, the crimping sleeve, deformed during crimping, covers the support sleeve onto the cable. After crimping, the deformed crimped area advantageously abuts against a portion of the cable (adjacent to the support sleeve). The latter offers the advantage of better cable support, particularly under bending loads, and can reduce predetermined breakage points. Good contact of the braided layer is achieved when the ratio of the axial length C, measured from the folded edge of the braided layer (first time) folded around the support sleeve to the distal end of the (undeformed) crimped area, to the outer diameter D of the contact surface of the crimped sleeve is C / D = 0.3-0.5, particularly C / D = 0.4-0.45. The contact surface is used to apply axial contact pressure to axially crimp the crimped sleeve and the support sleeve. The contact surface is advantageously located on the base of the crimped sleeve, particularly on the distal end of the crimped sleeve facing away from the support sleeve in the axial direction. The diameter D can correspond to the minimum diameter of the first opening of the base element. Such a ratio produces optimal compression, thereby achieving good electrical contact with the braided layer with minimal shielding loss. According to this application, the crimped sleeve may also have at least one through opening extending in the radial direction. The through-opening allows a technician to visually identify the braided layer in the assembled state. The crimping sleeve advantageously has a circumferential protrusion on its outer side (at least in some areas). On the one hand, this protrusion, in the assembled state, can be used to allow the crimping element to abut against a shoulder in the base element or tensioning element in the axial direction. On the other hand, in the case of axial crimping, the protrusion can also serve as a stop or similar element in the crimping tool used for axial crimping. For this purpose, the side of the protrusion facing the crimping area can be beveled, thus forming a crimping surface for the crimping tool at an angle to the axial direction. The crimping sleeve is advantageously conductive, especially metallic. For example, the crimping sleeve can include copper, brass, or other easily deformable and conductive materials.

[0015] The support sleeve typically rests generally against the cable sheath. For quick and easy assembly, the support sleeve may have a radially inwardly projecting shoulder for abutting against the end of the cable sheath. In one possible embodiment, for example, the support sleeve has an L-shaped cross-section. This allows the support sleeve to be pushed onto the cable from one side in the axial direction until the shoulder strikes the cable sheath. After positioning the support sleeve, the braided layer can be opened and folded around the support sleeve, or (at least in some areas) flipped onto the support sleeve. Subsequently, a crimp sleeve is pushed onto the support sleeve with the folded, opened braided layer thereon, such that the braided layer is positioned between the support sleeve and the crimp sleeve. Thus, in the assembled state with the crimp sleeve on the support sleeve, the braided layer can be positioned between the first contact surface of the crimp sleeve and the second contact surface of the support sleeve. The first and / or second contact surfaces may advantageously be oriented radially (perpendicular to the cable) or designed to be tapered, particularly tapered in the axial direction, at least in some areas (in the first area). In the case of axial compression, alignment of this (first) region is particularly advantageous because the contact pressure is greatest in this region on the one hand, and can be adjusted and / or measured with particular precision on the other. 20% to 40% of the exposed braided layer is advantageously disposed in this (first) region, or 20% to 40% of the contact surface is advantageously aligned in the radial direction. The first region of the first contact surface of the crimp sleeve can also transition to a second region, which extends substantially axially along the inner side of the crimp sleeve. Simultaneously, the first region of the second contact surface of the support sleeve can transition to a second region, which extends substantially axially along the outer side of the support sleeve. However, as mentioned above, a contact surface that is at least partially tapered is also possible. One advantage of the tapered embodiment, particularly in the first region, is that the angled contact surface enlarges the contact area, thus improving current dissipation in the braided layer.

[0016] Different areas of the corresponding contact surfaces advantageously transition to each other via rounded corners, thereby reducing damage to the braided layer. This is particularly advantageous when the second contact surface is located on the support sleeve. Regarding good electrical contact, the first and / or second contact surfaces may be provided with a conductive coating. However, the support sleeve is advantageously at least partially conductive, particularly metallic. For example, the support sleeve may be at least partially composed of copper or brass. It is advantageous to use the same material for the crimping sleeve and the support sleeve because the corresponding temperature dependencies of the parts to be crimped are similar.

[0017] For axial crimping of crimping elements, it is advantageous to design the support sleeve to be axially deformable. For this purpose, the support sleeve can have at least one deformation region for axial deformation. In the assembled state of the support sleeve within the crimping sleeve, the deformation region is advantageously located at an end opposite to the base of the crimping sleeve. Furthermore, it is particularly advantageous that, in the assembled state of the support sleeve within the crimping sleeve, and before crimping, the deformation region is at least partially located in the radial direction between the cable and the crimping region of the crimping sleeve. For example, the deformation region can be located on the inner side of the support sleeve. The deformation region can have at least one stress-relieving groove and / or at least one compression groove. With the aid of these grooves, the support sleeve can be better stretched or compressed axially. In each case, these grooves can be provided along a through opening in the support sleeve.

[0018] To create a good path for the wire to enter the housing interconnected with the fixing device from the braided layer of the cable, a contact spring for electrical contact with the crimping element can be provided, for example, between the base element and the crimping element (or between the tensioning element and the crimping element). The contact spring is advantageously radially deformable. In the assembled state, the contact spring advantageously applies radial contact pressure to the crimping element. The contact spring is advantageously annular or C-shaped in the axial direction. For example, a laminated spring or a layered spring can be used. The contact spring can be disposed in a radial groove in the base element and / or the crimping sleeve. The radial groove of the base element advantageously surrounds the first opening. However, according to embodiments, variations in the arrangement of the groove in the tensioning element are also conceivable. According to embodiments, the cross-section of the groove can be dovetail-shaped.

[0019] To assemble the fastening device, the cable braid at the end of the cable to be fastened can be exposed first. The fastening device can then be prepared, as the components have already been threaded onto the exposed cable in the installation sequence. For this purpose, the tensioning element is first pushed onto the cable, followed by the support sleeve. The support sleeve can be pushed to one end of the cable sheath and positioned there by its radial shoulder. The cable braid is then opened and placed around the support sleeve. The braid protruding from the support sleeve can be cut off. Alternatively, the braid dimensions can be correctly determined before applying the components. Afterward, the crimping sleeve is pushed onto the cable and then onto the support sleeve. The crimping sleeve and support sleeve are then crimped, particularly axially, so that the braid is advantageously and non-releasably secured between them. For axial crimping, the cable and crimping element are placed together in the assembly tool and crimped therein while applying force in the axial direction. After this step, the base element is pushed onto the cable. The base element advantageously has a stop for the crimping element. The base element can be interconnected with the tensioning element. If a clamping element is present, it is pushed onto the cable before the support sleeve is pushed up. Alternatively, when the clamping element has a corresponding slot, it can also be subsequently laterally clamped onto the cable. In the assembled state, a crimping element is then positioned between the tensioning element and the base element, or, if the clamping element is present, between the clamping element and the base element. When the cable has a foil / film, particularly a shielding foil / film, below the braid, the foil / film can be removed in some areas. Alternatively, the foil / film can be further guided along the cable without being flipped. However, when the foil / film is positioned above the braid, removal is particularly expedient because the foil / film hinders the folding back of the braid.

[0020] During the extrusion process, the tool can also leave embossing. Embossing can be applied to the outside of the crimping sleeve, such as in the crimping area and / or on the crimping surface. Embossing can display information related to the crimping parameters used, such as tool parameters, number of extrusions, pressure, manufacturer markings, etc. Furthermore, embossing can represent quality characteristics for the user. Attached Figure Description

[0021] Various aspects of the invention will be explained in more detail with reference to the exemplary embodiments shown in the accompanying drawings and the associated description. In the drawings,

[0023] Figure 2 The cross-sectional side view shows the results according to Figure 1 Variations in the fixing devices; and

[0024] Figure 3 A cable with a crimping element is shown. Detailed Implementation

[0025] Figures 1 to 2 A variation of the fixing device 1 according to the invention is shown in the assembled state on the cable 2. The cable 2 includes a conductor 18 having a braided layer 3 surrounding the conductor 18, particularly a shielding braided layer. An intermediate insulation layer 17 is provided between the braided layer 3 and the conductor 18. The braided layer 3 is surrounded from the outside by a cable sheath 19. However, other types of cables and structures are also possible. In the area of ​​the fixing device 1, the cable sheath 19 is removed, and one end of the braided layer 3 is exposed.

[0026] The fixing device 1 includes a base element 4 and a tensioning element 5 that can be interconnected with the base element. The base element 4 is used to mount the fixing device 1 onto, for example, a housing or the like (not shown). Therefore, the base element 4 has a base 9 with a support surface for support on the housing. A seal 23 for sealing the fixing device 1 to the housing can be provided on the base 9. In the illustrated case, the tensioning element 5 is a clamping nut, but other embodiments of the tensioning element are conceivable. The base element 4 has a first opening 7 extending axially for the cable 2 to pass through, while the tensioning element 5 has a second opening 8 extending axially for the cable 2 to pass through. The tensioning element 5 is particularly used to clamp a clamping element 22 disposed between the base element 4 and the tensioning element 5, and to fix the cable 2 and optionally seal the cable. The clamping element 22 is advantageously made of a deformable material. Furthermore, a crimping element 6 is provided between the base element 4 and the tensioning element 5. The crimping element 6 is disposed axially between the clamping element 22 and the base element 4. Furthermore, a contact spring 20 is provided radially in the base element 4, the contact spring 20 being disposed in a groove 21 radially surrounding the first opening 7. The contact spring 20 ensures improved electrical contact between the crimping element 6 and the base element 4.

[0027] The crimping element 6 includes an outer crimping sleeve 10 and an inner support sleeve 11, the support sleeve 11 being disposed within the crimping sleeve 10, which is advantageously axially deformable. The cable 2 having the crimping element 6... Figure 3The figure shows the undeformed crimping sleeve 10 (before crimping) in the lower part of the figure. The deformed crimping sleeve 10 (after crimping) is shown in the upper part of the figure. In both states, the braided layer 3 is disposed between the crimping sleeve 10 and the support sleeve 11. After crimping, the crimping element 6 is advantageously fixed to the cable 2. The deformed crimping area 12 can abut against some areas of the cable 2 adjacent to the support sleeve 11. Embossing 25 produced by crimping or crimping tools can be arranged on the outside of the crimping sleeve 10, for example, on the crimping area 12. Before crimping, the deformable crimping area 12 extends in the axial direction. In the assembled state where the support sleeve 11 is in the crimping sleeve 10, the crimping area 12 protrudes from the support sleeve 11 in the axial direction (see the lower part of the figure). In the illustrated variation, the length C defined from the axial end of the (undeformed) crimped area 12 to the folded edge of the braided layer is perpendicular to the outer diameter D of the contact surface 26 of the crimped sleeve 10 (see...). Figure 2 The ratio of C / D is C / D = 0.3-0.5. The contact surface 26 is used to apply axial contact pressure around the crimping sleeve 10 and the support sleeve 11 for crimping. For crimping, the outer side of the crimping sleeve 10 has a surrounding protrusion 24. In the assembled state, the surrounding protrusion is supported in the axial direction on the stop portion 14 of the base element 4.

[0028] Alternatively, the support sleeve 11 may have at least one deformation region 15 for axial deformation. In the illustrated case, the support sleeve 11 has multiple grooves on its inner side facing the cable 2, which can serve as stress-relieving grooves and / or compression grooves in the event of axial deformation. It can be seen that, in both deformed and undeformed states, the support sleeve 11 has a radial shoulder 16 for abutting against the end of the cable sheath 19. Additionally, the crimp sleeve 10 includes a stop 14 in the axial direction for supporting the sleeve 11. Thus, the support sleeve 11 can be easily and quickly positioned onto the cable 2 by means of the crimp sleeve 10. Furthermore, it is advantageous that the crimp sleeve 10 has at least one radial through-opening 13, allowing the intermediate braided layer 3 to be visually identified through the through-opening 13 in the assembled state. In the deformed state, the support sleeve 11 is surrounded and secured by the crimp sleeve 10 and the cable 2.

[0029] To assemble the shown fixing device 1, the braided layer of the cable 2 beneath the cable sheath 19 is first exposed. Then, the tensioning element 5 is threaded onto the cable 2, followed by the clamping element 22 and the support sleeve 11 being threaded onto the cable. The support sleeve 11 is pushed to one end of the cable sheath 19 by means of the radial shoulder 16 and positioned there. Subsequently, the braided layer 3 of the cable 2 is opened and placed around the support sleeve 11. Any protruding braided layer 3 can be cut off. Next, the crimping sleeve 10 is pushed onto the cable 2 and above the support sleeve 11. The braided layer 3 is then axially crimped between the crimping sleeve 10 and the support sleeve 11. After this step, the base element 4 is pushed onto the cable 2 and interconnected with the tensioning element 5.
