Description

[Technical field]

[0001] The present invention relates to a retaining device for retaining a cable provided with braid, in particular a braided shield. [Background technology]

[0002] Retaining devices of this kind may be used on the one hand for strain relief of the cable and on the other hand for electromagnetic shielding and elimination of line disturbances. For this purpose, the cable is axially fixed and an electrical contact connection is established with the cable braid arranged under the outer cable sheath (insulation). From the prior art, a great number of different retaining devices are known. Current retaining devices usually comprise a sleeve-like base element which is arranged over the cable, a clamping element which fixes the cable and a tensioning element which may be connected to the base element and which positions the clamping element on the base element. Depending on the application, contact elements for the electrical contact connection of the cable braid may likewise be provided.

[0003] An example is DE 19523795, which discloses a cable gland for a shielded switch cable. The cable gland comprises a grounded clamping sleeve which surrounds the exposed shield sheath and clamps it so that a contact connection is made. The cable gland additionally comprises a crush sleeve which is divided into a thin-walled crushing part and a thick-walled support part. Here, the crushing part of the crush sleeve is pressed onto the sheath-free end part of the switch cable and is crushed against this end part by crimping. In this case, the exposed shield sheath is turned over and placed over the support part, and the clamping sleeve with the clamping part is pressed onto the support part including the shield sheath and is likewise crushed against this support part by (radial) crimping.

[0004] DE 10 2013 201531 discloses an electrical contact between the shield of a shielded line and a housing wall, in which the line is surrounded by a contact sleeve which is in electrical contact with the shield and the housing wall, and which is crimped onto the outer sheath of the line.

[0005] Known retaining devices for cables with braided shielding often result in poor electrical contact, which reduces the quality of the shielding and, in particular, leads to high shielding losses. Poor electrical contact can result, for example, when the braid is crimped too tightly, but also when it is too weak. For a good quality of shielding, therefore, it is not only necessary to use maximally shielded lines, but also to use retaining devices with good electromagnetic compatibility. In this case, it must be ensured that the contact of the shielding, in addition to meeting the electrical requirements, is mechanically stable as well. Summary of the Invention

[0006] SUMMARY OF THE DISCLOSURE It is an object of the present invention to provide a holding device with improved connection of the cable braid.

[0007] The retaining device according to the invention is for a cable with a braid located at least partially on the outside. The cable may comprise at least one conductor and a cable sheath that protects the braid. In the assembly area of ​​the cable, where the retaining device is to be attached, however, the cable sheath is preferably partially removed, whereby the braid is arranged on the outside. Depending on the configuration, the cable may be a shielded cable. The braid may be a braid shield of the cable. Alternatively or additionally, the braid may be used for earthing. Depending on the embodiment, the cable may also have, in addition to the braid, a sheet, in particular a protective sheet (such as, for example, a metal sheet and / or a metallized plastic sheet) above or below the braid.

[0008] The holding device according to the invention comprises a base element and a tension element and a crimping element which can be operatively connected to the base element. The crimping element is used in particular for fixing and contacting the braid to the crimping element by crimping. In this case, an axial crimping is particularly advantageous. The fixation of the cable or braid in the crimping element is preferably irremovable, so that a secure and durable connection is obtained. If the braid is used as a shield, such a connection results in a connection for a permanent and high-quality electrical contact connection. Axial crimping distributes the forces evenly on the braid and results in a symmetrical pressing. This results in less shielding losses and generally a more environmentally friendly connection. Furthermore, in the case of axial pressing, the influence of the resulting tolerances, which is caused, for example, by an unevenly spread braid, is reduced in contrast to radial pressing. However, in addition to the influence on the shield contact, axial crimping has a favorable effect on the insulation properties of the cable. This is because adverse loads, such as pinching of the cable insulation, can be minimized.

[0009] In the axial direction, a first opening for guiding the cable extends through the base member. Furthermore, the base member advantageously comprises a base for mounting and fixing the base member on the housing. Advantageously, the mounting surface of the base is formed such that the mounting surface at least partially contacts the housing. The base member may be manufactured from an electrically conductive material and / or may have an electrically conductive coating. In one possible embodiment, the base member has first operative coupling means, for example for operative coupling with the housing. The holding device may have a screw as the first operative coupling means. However, other types of operative coupling are also conceivable. Furthermore, the base member may have another (second) operative coupling means, for example a screw, for operative coupling with the tension member.

[0010] The tension member has a second axially extending opening for guiding the cable, which opening is advantageously arranged coaxially with the first opening. In one possible embodiment, the tension member has a third operative coupling means for operatively coupling with the second operative coupling means of the base member. In one possible embodiment, the tension member is a tension nut that can be screwed to the base member. The tension member may be used to fix a crimping member that is arranged between the base member and the tension member, as will be explained in detail below, and also to fix a clamping member, if necessary.

[0011] The clamping element may be used for additional holding and clamping of the cable in the holding device. Depending on the application, the clamping element may also be used for sealing the cable against the holding device. In the assembled state, the clamping element may be arranged in the axial direction between the base element and the tension element. The clamping element may be formed in one piece or in multiple pieces. Depending on the configuration, the clamping element may have, for example, at least one slit, in particular in the axial direction. The slit may be formed corrugated. A corrugated slit has the advantage that the clamping element can be opened (or widened) for inserting the cable from the side, but in the assembled state, the clamping element is not displaced. Advantageously, the clamping element consists of a deformable material, in particular a ductile material. Advantageously, the clamping element is configured to be deformable in particular radially and / or to be elastic in the radial direction. This may be due to the material properties and / or may be achieved by shaping of the clamping element. That is to say, the clamping element may have, for example, at least one slit. The at least one slit may be oriented in the radial or axial direction. Likewise, the at least one slit may be formed radially and / or axially uninterrupted, so that, for example, the annular clamping element is C-shaped. If a clamping element is provided, the crimping element serves in particular for the electrical contact-connection of the braid, while the clamping element serves to hold the cable, absorb tensile forces and, if necessary, seal the cable against the holding device. In this way, the braid is not overly stressed and the electrical contact-connection is locally separated from the fixed part of the cable.

[0012] In one preferred embodiment, the holding device may have an anti-twisting device. This anti-twisting device may be used to prevent twisting of the base member relative to the clamping member. For this purpose, the anti-twisting device may comprise at least one first fixing member arranged on the clamping member and a second fixing member arranged on the base member. In the assembled state, the fixing members at least partially engage with each other and circumferentially position the clamping member on the base member. In this case, the at least one first fixing member may be arranged on an outer peripheral surface of the clamping member. The outer peripheral surface is directed away (outward) from an opening extending axially through the clamping member for guiding the cable. Furthermore, the at least one second fixing member may be arranged on an inner peripheral surface of the base member. The inner peripheral surface of the base member is axially on the side of the first opening for guiding the cable. At least one first locking member may be formed in the form of a recess, whereas at least one second locking member may be a profiled member which in the assembled state at least partially engages in said recess (or vice versa). Advantageously, a plurality of (first and second) locking members are arranged over the respective circumferential surfaces, in particular at regular intervals relative to one another. For example, the anti-twisting device or the first locking member and / or the second locking member may be formed as interlocking teeth and / or indentations. The indentations may represent engraved or cut portions on the respective circumferential surfaces. The indentations are usually produced by knurling.

[0013] In the assembled state, the crimping member may be arranged between the base member and the tensioning member or between the base member and the clamping member. By tightening the tensioning member, the clamping member may be tensioned and positioned against the crimping member and the crimping member against the base member. The crimping member is advantageously multi-piece, in particular two-piece. The crimping member may, for example, comprise an outer crimping sleeve and an inner support sleeve arranged in the crimping sleeve. In the assembled state of the cable in the holding device, the (exposed) braid is arranged between the crimping sleeve and the support sleeve. In this case, the crimping sleeve may be crimped, in particular axially crimped, to the inner support sleeve such that the braid is fixed between the crimping sleeve and the support sleeve.

[0014] For crimping, the crimping sleeve may preferably have a crimping region. The crimping region may extend in the axial direction. For good deformation, the crimping region is advantageously thin-walled. The crimping region may protrude from the base of the wall thickness of the crimping sleeve. The crimping sleeve may have a receiving space for receiving the support sleeve. For positioning the support sleeve in the crimping sleeve, the crimping sleeve may alternatively or supplementarily comprise a stop for the support sleeve on its inner surface in the axial direction. That is to say, the crimping sleeve is pushed axially from one side into the support sleeve until the support sleeve reaches the receiving space and comes into contact with the stop. In the assembled state of the support sleeve in the crimping sleeve or in the receiving space and in the (not yet) deformed state of the crimping region, the crimping region preferably protrudes beyond the support sleeve in the axial direction. In this way, in the deformed state after crimping, the crimping sleeve covers the support sleeve with respect to the cable. After crimping, the deformed crimping area is advantageously partially (in the vicinity of the support sleeve) tightly fitted to the cable. The tight fit to the cable has the advantage that the cable is better supported, especially under bending loads, and the predetermined breakage points can be reduced. A good contact connection of the braid is achieved if the length C, measured in the axial direction from the folded edge where the braid is (firstly) folded back around the support sleeve to the distal end of the (undeformed) crimping area, has a ratio of C / D=0.3-0.5, in particular C / D=0.4-0.45, to the outer diameter D of the pressing surface of the crimping sleeve. Here, the pressing surface is used to apply an axial pressing force to the crimping sleeve and the supporting sleeve for crimping. The pressing surface is advantageously arranged at the base of the crimping sleeve, in particular at the distal end of the crimping sleeve, which is located axially opposite to the supporting sleeve. The diameter D may correspond to the minimum diameter of the first opening of the base member. Such a ratio ensures an optimal crimp for good electrical contact of the braid with little shielding losses. Furthermore, depending on the application, the crimping sleeve may have at least one radially extending through-opening, through which the assembler can visually inspect the braid in the assembled state.Advantageously, the crimping sleeve has a projection on its outer surface that extends (at least partially) in the circumferential direction. This projection can be used, on the one hand, to stop the crimping member in the axial direction on a shoulder of the base member or tension member in the assembled state. On the other hand, this projection can also be used, during axial crimping, as a stop on a crimping tool or the like for axial crimping. For this purpose, the face of the projection facing the crimping area can be inclined, so that an axially inclined crimping surface for the crimping tool is formed. Advantageously, the crimping sleeve is electrically conductive, in particular metallic. For example, the crimping sleeve can contain copper, brass or another well deformable and electrically conductive material.

[0015] The support sleeve is usually placed substantially on the cable sheath. For fast and easy assembly, the support sleeve may have a radially inwardly located shoulder for contacting one end of the cable sheath. In one possible embodiment, the cross section of the support sleeve is, for example, L-shaped. That is to say, the support sleeve is pressed onto the cable from one side in the axial direction up to a stop of the shoulder on the cable sheath. After positioning of the support sleeve, the braid may be unfolded and folded (at least partially) around the support sleeve or may be wrapped. The crimp sleeve is then pressed into the support sleeve together with the braid unfolded and folded onto the support sleeve, so that the braid is located between the crimp sleeve and the crimp sleeve. In the assembled state of the crimp sleeve on the support sleeve, the braid may be located between a first contact-connection surface of the crimp sleeve and a second contact-connection surface of the support sleeve. Advantageously, the first contact-connection surface and / or the second contact-connection surface may at least partially (in the first region) be oriented radially (normal to the cable) or may be configured conically, in particular in the axial direction. This orientation of the (first) region is particularly advantageous in the case of axial compression, since in this region the pressing force is on the one hand greatest and on the other hand can be adjusted and / or measured particularly simply and precisely. Advantageously, 20% to 40% of the exposed braid is arranged in this (first) region, or 20% to 40% of the contact-connection surface is preferably radially oriented. Furthermore, the first region of the first contact-connection surface of the crimping sleeve may transition along the inner surface of the crimping sleeve into a second region extending substantially in the axial direction. Meanwhile, the first region of the second contact-connection surface of the support sleeve may transition along the outer surface of the support sleeve into a second region extending substantially in the axial direction. However, as mentioned above, at least partially conical contact surfaces are also conceivable.One advantage of the conical embodiment is that, especially in the first region, the angled contact surface increases the contact area and thus provides a better conduction of the current in the braid.

[0016] Advantageously, the different regions of the respective contacting surfaces merge into one another via rounded regions, so that damage to the braid is reduced. This is particularly advantageous for the second contacting surface, which is arranged on the support sleeve. For good electrical contacting, the first contacting surface and / or the second contacting surface can be provided with an electrically conductive coating. Advantageously, however, the support sleeve is at least partially electrically conductive, in particular metallic. For example, the support sleeve can be at least partially made of copper or brass. The use of the same material for the crimping sleeve and the support sleeve is advantageous in that the respective temperature dependencies of the components to be crimped are similar.

[0017] For the axial crimping of the crimping elements, it is advantageous if the support sleeve is designed to be deformable in the axial direction. For this purpose, the support sleeve may have at least one deformation area for axial deformation. In the assembled state of the support sleeve in the crimping sleeve, the deformation area is advantageously arranged at the end of the crimping sleeve opposite the base. Furthermore, it is particularly advantageous if, in the assembled state of the support sleeve in the crimping sleeve and before crimping, the deformation area is arranged at least partly radially between the cable and the crimping area of ​​the crimping sleeve. The deformation area may, for example, be arranged on the inner surface of the support sleeve. The deformation area may have at least one strain relief groove and / or crushing groove. These grooves allow the support sleeve to be stretched in the axial direction better. These grooves may each extend around a guide opening of the support sleeve.

[0018] For a good routing of the electrical lines from the braid of the cable to, for example, a housing to which the holding device is operatively connected, a contact spring for the electrical contact connection of the crimping member may be arranged between the base member and the crimping member (or alternatively between the tension member and the crimping member). Advantageously, the contact spring is radially deformable. In the assembled state, the contact spring advantageously exerts a radial pressing force on the crimping member. The contact spring is advantageously annular or C-shaped in the axial direction. For example, a leaf spring or a flat spring may be used. The contact spring may be arranged in a radial groove of the base member and / or the crimping sleeve. In this case, the radial groove of the base member advantageously extends around the first opening. However, depending on the configuration, a variant is also conceivable in which the groove is arranged on the tension member. Depending on the configuration, the groove may have a swallow-tail shape in cross section.

[0019] To assemble the retention device, first the braid of the cable may be exposed at the cable end to be fixed. The retention device may then be prepared by threading the individual components in the assembly sequence over the exposed cable. For this purpose, first the tension member and then the support sleeve are pressed onto the cable. The support sleeve may be pressed with a radial shoulder up to the end of the cable sheath and positioned there. The braid of the cable is then expanded and placed around the support sleeve. The braid protruding from the support sleeve may be cut off. Alternatively, the braid may be appropriately sized before the components are provided. Afterwards, a crimping sleeve is pressed onto the cable and the support sleeve. In this case, the crimping sleeve and the support sleeve are crimped, in particular in the axial direction, so that the braid is preferably irremovably fixed between them. For axial crimping, the cable is inserted into an assembly tool together with the crimping member, where it is crimped with an axial force. After this step, the base member is pressed onto the cable. The base element preferably has a stop for the crimping element. In this case, the base element may be operatively connected to the tension element. If a clamping element is provided, it is pushed in before the support sleeve is pushed onto the cable. Alternatively, if the clamping element has a corresponding slit, it may be inserted laterally onto the cable. In this case, in the assembled state, the crimping element is arranged between the tension element and the base element or, if provided, between the clamping element and the base element. If the cable has a sheet below the braid, in particular a shielding sheet, this sheet may be partially removed. Alternatively, this sheet may be guided further along the cable without having to be folded back. However, if a sheet is arranged above the braid, it is particularly recommended to remove it, since this prevents the braid from being folded back.

[0020] Furthermore, the tool may leave further markings during crimping. The markings may be arranged on the outer surface of the crimping sleeve, for example on the crimping area and / or on the crimping surface. The markings may indicate information about the crimping parameters used, such as tool parameters, crimping times, pressing force, manufacturer logo, etc. Complementarily, the markings may represent quality indicators for the user.

[0021] Aspects of the present invention will now be described in detail with reference to the embodiments illustrated in the accompanying drawings and the corresponding description. [Brief description of the drawings]

[0022] [Figure 1] 1 shows a perspective partial cross-sectional view of one variation of a retaining device according to the invention. [Diagram 2] 2 shows a longitudinal section of a variation of the holding device shown in FIG. 1; [Diagram 3] 1 shows a cable with a crimping member. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] 1 to 2 show one variant of the holding device 1 according to the invention in the assembled state on a cable 2. The cable 2 comprises a conductor 18 and a braid 3, in particular a braid shield, which surrounds the conductor 18. Between the braid 3 and the conductor 18 an intermediate insulation 17 is arranged. From the outside, the braid 3 is surrounded by a cable sheath 19. However, other types of cables and constructions can be realised as well. In the area of ​​the holding device 1, the cable sheath 19 has been removed, leaving the ends of the braid 3 exposed.

[0024] The holding device 1 comprises a base member 4 and a tensioning member 5 which can be operatively connected to the base member 4. The base member 4 is used for fastening the holding device 1, for example, to a housing (not shown). For this purpose, the base member 4 has a base 9 with a rest surface for resting on the housing. A seal 23 can be arranged on the base 9 for sealing the holding device 1 to the housing. The tensioning member 5 is a tensioning nut in the illustrated case, but other configurations of the tensioning member are also conceivable. The base member 4 has a first axially extending opening 7 for guiding the cable 2, whereas the tensioning member 5 has a second axially extending opening 8 for guiding the cable 2. The tensioning member 5 is used in particular to clamp a clamping member 22 arranged between the base member 4 and the tensioning member 5, to hold the cable 2 and, if necessary, to seal it. Advantageously, the clamping member 22 consists of a deformable material. Furthermore, a crimping member 6 is arranged between the base member 4 and the tensioning member 5. The crimping member 6 is arranged axially between the clamping member 22 and the base member 4. Radially, a contact spring 20 is arranged in the base member 4 in a groove 21 extending radially around the first opening 7. The contact spring 20 provides an improved electrical contact from the crimping member 6 to the base member 4.

[0025] The crimping element 6 comprises an outer crimping sleeve 10 and an inner support sleeve 11 arranged in the crimping sleeve 10 and which is advantageously axially deformable. In FIG. 3, a cable 2 with the crimping element 6 is shown. In the lower part of the figure, the undeformed crimping sleeve 10 (before crimping) is shown. In the upper part of the figure, the deformed crimping sleeve 10 (after crimping) is shown. In both states, the braid 3 is arranged between the crimping sleeve 10 and the support sleeve 11. After crimping, the crimping element 6 is advantageously rigidly connected to the cable 2. In this case, the deformed crimping region 12 may bend around the support sleeve 11 and partially around the cable 2. An impression 25 of the crimping or of the crimping tool may be arranged on the outer surface of the crimping sleeve 10, for example in the crimping region 12. Before crimping, the deformable crimping region 12 extends in the axial direction. The crimping area 12 protrudes in the axial direction beyond the support sleeve 11 in the assembled state of the crimping sleeve 10 (see the lower part of the figure). In the illustrated variation, the length C, defined as the length from the end of the (undeformed) crimping area 12 to the folded end of the braid in the axial direction, has a ratio C / D=0.3-0.5 to the outer diameter D of the pressing surface 26 of the crimping sleeve 10 (see FIG. 2). Here, the pressing surface 26 is used to apply an axial pressing force to the crimping sleeve 10 and the support sleeve 11 for crimping. For crimping, the crimping sleeve 10 has a circumferentially extending projection 24 on its outer surface. In the assembled state, this projection 24 contacts the stopper 14 of the base member 4 in the axial direction.

[0026] It is furthermore possible for the support sleeve 11 to have at least one deformation region 15 for deformation in the axial direction. In the illustrated case, the support sleeve 11 has a number of grooves on its inner surface facing the cable 2, which may be used as strain relief grooves and / or crushing grooves during axial deformation. It can be seen that the support sleeve 11 has a radial shoulder 16 for contacting the end of the cable sheath 19, both in the deformed and in the undeformed state. Furthermore, the crimping sleeve 10 comprises a stop 14 for the support sleeve 11 in the axial direction, which means that the support sleeve 11 and, via it, the crimping sleeve 10 can be positioned on the cable 2 in a simple and quick way. It is furthermore advantageous for the crimping sleeve 10 to have at least one radial through-opening 13, so that in the assembled state the intervening braid 3 can be visually seen via this through-opening. In the deformed state, the support sleeve 11 is surrounded and held by the crimp sleeve 10 and the cable 2 .

[0027] To assemble the illustrated holding device 1, first the braid of the cable 2, which lies beneath the cable sheath 19, can be exposed. The tensioning member 5, the clamping member 22 and the support sleeve 11 can then be threaded in turn onto the cable 2. The support sleeve 11 can be pushed up to the end of the cable sheath 19 by means of the radial shoulder 16 and positioned there. The braid 3 of the cable 2 is then expanded and placed around the support sleeve 11. The protruding braid 3 can be cut off. The crimping sleeve 10 can then be pushed onto the cable 2 and the support sleeve 11. The braid 3 can then be axially crimped between the crimping sleeve 10 and the support sleeve 11. After this step, the base member 4 is pushed onto the cable 2 and is operatively connected with the tensioning member 5. [Explanation of symbols]
