Definitions
- the invention relates to a cable strain relief which has a sheathing of the cable, means for fastening it to a body which absorbs the tensile load and a clamping part with which the cable is pressed together and fixed relative to the sheathing.
- DE-OS 23 40 314 describes a strain-relieved cable bushing in which a holding element, for example made of an elastic plastic, is seated in an opening in a housing wall and is molded onto the cable.
- a holding element for example made of an elastic plastic
- the outer cable sheath in the area of the extrusion coating is removed and the sheaths of the individual wires are roughened so that sufficient strain relief for the individual wires is ensured.
- DE-OS 27 48 419 describes a seal for a submersible motor or the like. The seal closes an opening in the housing for the motor through which a covered electrical strand is passed.
- the seal includes a pipe socket attached to the inside of the housing and coaxially surrounding the opening, and a cylindrical sealing element made of an elastomeric material with an axial passage for the encased strand.
- the outer diameter of the sealing element is larger than the inner diameter of the pipe socket, and the diameter of the axial passage is larger than the outer diameter of the casing. If the sealing element is pressed into the pipe socket, the diameter of the passage is reduced and the sealing element presses against the casing.
- a clamping ring is attached to the inside of the casing on the coated strand such that it comes into contact with the sealing element when the strand is pulled outward with respect to the housing.
- DE-OS 34 09 906 describes a cable grommet for fixing and stiffening a cable guided through an opening in a device.
- the cable grommet consists of an elongated hollow body made of a resilient material and has a thickening in the region of the opening with a groove arranged therein.
- the inner diameter of the hollow body is smaller than the outer diameter of the cable at least at one clamping point.
- the opening has a funnel-shaped extension inside the device. The thickening of the hollow body lies against the extension within the groove.
- the thickening becomes against the funnel-shaped extension pressed and thus the diameter of the hollow body in the region of the extension is reduced, with the result that the more that is pulled, the more the hollow body is pressed against the cable.
- the individual cores of a multi-core cable are also reliably strain relieved.
- the cable is clamped in by the clamping part anchored in the sheathing in such a way that the individual wires are relieved of tension towards the sheathing.
- the sheathing is advantageously molded onto the clamping part and the cable piece by means of extrusion coating.
- the clamping part has a U-profile, the distance between the legs being smaller than the diameter of the cable in the non-compressed state, and if the cable is held between the two legs.
- the clamping part shaped in this way can be easily attached and can be designed so massively that it can exert considerable pressure on the cable. Due to its shape, it is strongly anchored in the sheath - and with it the pinched cable.
- the clamping part is designed as a sleeve which is pressed together at least at one point to such an extent that the smallest distance between opposing regions of the inner wall of the sleeve is smaller than the diameter of the cable in the non-compressed state.
- the cable is passed through the sleeve.
- the anchoring of the clamping part designed in this way in the casing can be further improved if the sleeve has at least one terminal flange-like widening.
- the covering advantageously consists of an elastic plastic or a rubber-like material. These materials can be easily sprayed on in the uncured state and then polymerized or vulcanized.
- plastics from the group of polyvinyl chloride, polyurethane and a mixture of the two materials are particularly favorable.
- the clamping part can consist of one that permanently deforms during bending and one . elastic material exist. This option also opens up many possible variations in the manufacture of the cable strain relief, in particular if the sheathing is produced by means of extrusion coating. If the clamping part consists of a permanently bending material, the cable is pressed together with the clamping part and then the cable with the attached clamping part is placed in the injection mold. If the clamping part consists of an elastic material, it is necessary that a device that compresses the clamping part and the cable is present in the injection mold, the shape of the clamping part and the cable produced thereby being "frozen" during the encapsulation.
- the clamping part advantageously consists of a metal or a plastic with a higher melting point than the enveloping material.
- the means for attaching the cable strain relief to the sheathing are directly molded on and / or are set. Further advantageous configurations of the means are present if the means form widenings projecting from the sheathing, if the means have at least two mutually facing boundaries and are adapted to the body in such a way that the two boundaries when the cable strain relief is fastened to the body lie against at least one wall of the body, and if each of the two mentioned limitations and an adjoining region of the covering not belonging to an extension encompass an edge of the wall. All of the structural elements required in these configurations, which have to be produced on or in the casing, can be molded directly when the clamping part and the cable piece are encapsulated. Special precautions on the body which is to take up the strain relief for taking up the cable strain relief according to the invention are not necessary. Cable strain reliefs designed in this way can be very easily attached to the body.
- the cable strain relief according to the invention can advantageously be used if the body is designed as a housing with a feedthrough for the cable, if the sheath fits into the feedthrough in some areas, if the means are designed so that they feed into the feedthrough inserted cable strain relief with the above-mentioned limits on the wall of the housing that delimits the bushing. If the cable strain relief is inserted into the bushing, which is required in any case for the insertion of the cable into the housing, then a particularly stable fastening of the cable strain relief on the housing can be achieved in a simple manner.
- the cable strain relief according to the invention is advantageously equipped in such a way that the mutually facing limits of the means form the walls of at least one annular groove so that the annular groove has a width , which is adapted to the thickness of the wall (walls) of the housing cover or the lower housing part, that the outer and the inner contour of the annular groove is geometrically approximately similar to the opening formed by the one pair of recesses and that the inner diameter of the annular groove is the same as or smaller and its outer diameter is larger than the diameter of the bushing.
- the annular groove is also produced when the cable and the clamping part are encapsulated, and no additional changes are required on the housing in addition to the recesses which are required anyway.
- this embodiment of the cable strain relief according to the invention there is a further advantage that it closes the passage moisture-tight.
- the fastening of the cable strain relief to the housing - in particular when the hood is removed - can be improved further if the housing is double-walled and the bushing is formed from two pairs of mutually abutting recesses in the housing and the inner walls of the housing hood or the lower housing part if an annular groove is provided for each pair of recesses and if the position of the two ring grooves relative to one another is adapted to the position of the two pairs of recesses relative to one another.
- the clamping part is arranged in the region of the sheathing framed by the ring grooves.
- an advantageous embodiment of the cable strain relief according to the invention is equipped in such a way that the sheath as a means has a directly formed extension which projects from it and surrounds it in a ring shape, such that an extension is attached to it the area of the casing bordering the extension fits through the opening, that the extension lies against the housing wall when the cable strain relief is inserted into the opening and protrudes all around the edge of the opening, and that the other means is attached to the area adjacent to the extension is.
- a mechanically particularly stable anchoring of the cable strain relief in the opening is provided if at least one hole is formed in the area adjacent to the extension which is approximately parallel to the extension.
- the extension runs approximately at a distance from the extension, which is equal to or greater than the thickness of the housing wall, and if a pin that fits into the hole is present as another means.
- the hole, as well as the extension can be molded directly when the clamping part and the cable piece are overmolded. The pin is only inserted into the hole after the casing has been pushed into the opening until the extension on the housing wall stops. The pin prevents the cable strain relief from being pulled out of the opening.
- the cable strain relief can no longer be moved relative to the housing and the opening is closed moisture-tight.
- the anchoring of the cable strain relief can be improved even more if two holes, one on each side of the cable, are provided and the pin is designed as a U-shaped bent clip, the distance between the legs of which is equal to the distance between the holes.
- a further very stable anchoring of the cable strain relief in the opening can be achieved if an annular groove is formed in the area adjacent to the extension, which lies in a plane that runs approximately parallel to the extension, which is approximately a distance of of the extension, which is equal to or greater than the thickness of the housing wall and if, as another means, a clip which fits into the annular groove is present.
- the annular groove can be formed directly when the clamping part and the cable piece are encapsulated.
- the clip is only pushed into the ring groove after the Wrapping has been pushed into the opening until the extension on the housing wall stops.
- the clamp prevents the cable strain relief from being pulled out of the opening. If the distance between the extension (measured at the outer edge facing the annular groove) and the annular groove is equal to the thickness of the housing wall, the cable strain relief can no longer be moved relative to the housing and the opening is closed in a moisture-tight manner.
- the feedthrough and the cut parallel to the feedthrough have approximately the same non-circular shape through the wrapping area inserted in the feedthrough. This ensures that the cable strain relief is secured against rotation.
- FIG. 1 shows a longitudinal section through an exemplary embodiment of the cable strain relief according to the invention, including cutouts from a cable and a housing wall
- FIG. 2 shows in cross section the exemplary embodiment shown in FIG. 1 along the line 2-2 shown in FIG. 1,
- FIG. 3 shows a longitudinal section through another exemplary embodiment of the cable strain relief according to the invention, including sections from a cable and a housing wall,
- FIG. 5 shows a longitudinal section through a further exemplary embodiment of the cable strain relief according to the invention, including a section from a cable and a housing wall and
- FIG. 6 shows in front view in the direction of th e outside of the housing and partly in section auf ⁇ the Aus ⁇ shown guide 5, for example in Fig..
- a cable strain relief 1 shown in FIGS. 1 and 2 belongs to a housing which consists of a housing hood and a lower housing part and which is double-walled at least where the housing hood and the lower housing part abut one another, that is to say that the housing hood has a housing wall 12 and an inner wall 13 and the lower housing part has a housing wall 14 and an inner wall 15.
- a recess is formed in the mutually facing edges of the housing and inner walls, the two recesses 8 and 9 in the housing walls 12 and 14 and the two recesses 10 and 11 in the inner walls 13 and 15 being opposite one another and complementing each other to form circular openings.
- the two openings form a passage for "the cable, into which the cable strain relief 1 is fitted in the arrangement shown in FIG. 1.
- the cable strain relief 1 consists of a sheath 2 and a clamping part 6.
- the clamping part 6 has a U-profile and is plugged onto a cable 3. Since the leg distance of the clamping part 3 is smaller than the cable diameter, the cable 3 is compressed by the clamping part 6.
- the clamping part 6 and a cable area on both sides of the clamping part 6 are extrusion-coated with the sheath 2.
- the clamping part 6 is embedded in a circular cylindrical region 23 of the casing 2, which has two annular grooves 4 and 5 which lie in planes perpendicular to the cylinder axis, the clamping part 6 being arranged between the planes.
- the annular grooves 4 and 5 are so adapted in their dimensions and in their spacing from one another to the formation of the recesses 8 and 9 or 10 and 11 and their position relative to one another that when the cable strain relief is in the bushing, the housing is closed Edges of the recesses 8 and 9 in the annular groove 4 and the edges of the recesses 10 and 11 in the annular groove 5 fit so precisely that a mechanically stable and moisture-tight connection between the housing and the cable strain relief 1 is ensured.
- the circular cylindrical region 23 of the casing 2 with the ring grooves 4 and 5 is adjoined in a stepped manner on the one side by a further circular cylindrical region and on the other side by a conical region, which narrows with increasing distance from the region 23.
- the sheath 2 can consist of an elastic plastic, for example of polyvinyl chloride, polyurethane or a mixture of these two substances, or of a rubber material that is vulcanized onto the cable 3.
- the clamping part 6 consists of a metal or a hard plastic with a higher melting point than the material from which the casing 2 is made. The material from which the clamping part 6 is made permanently deforms when it is bent or is elastic. In the former case, the cable 3 is pressed together with the clamping part 6 during the production of the cable strain relief, and then the cable region, which includes the compressed point, is placed in the mold for extrusion coating.
- the shape must be such that the cable 3 and the clamping part 6 are pressed together during the spraying and the shape of the cable and clamping part produced in the process is "frozen" during the encapsulation.
- the clamping part 6 compresses the cable 3 and thereby - in the case of multi-core cables - presses the individual wires 7 against the insulation (see FIG. 2), tensile forces from the outside can no longer be exerted on the connection points inside the device via a single or several individual wires be transmitted. Rather, the tensile forces are transmitted via the insulation to the clamping part 6 and from there via the casing 2 to the housing. It is also advantageous that the clamping part 6 is strongly anchored in the casing 2 due to its shape.
- the cable strain relief 1 is inserted with the ring grooves 4 and 5 into the recesses 9 and 11 in the lower housing wall 14 and in the inner wall 15 with the housing hood removed.
- the housing hood is then placed in such a way that the recesses 8 and 10 engage in the ring grooves 4 and 5 in the housing wall 12 and in the inner wall 13, respectively.
- a cable strain relief 16 shown in FIGS. 3 and 4 belongs to a housing in which the cable 3 is guided into the housing through a circular opening 21 in a housing wall 20.
- the cable strain relief 16 In order for the cable strain relief 16 to be inserted into the opening 21 and to be fixed in it, it must have some special constructional features by which it differs from the cable strain relief 1, but only by this. This means that what has been said above in connection with the discussion of the cable strain relief 1 for the * clamping part 6, for the sheathing 2, for compressing the cable 3, for overmolding the clamping part 6 and the cable 3 and also for the materials used is, the same applies to the cable strain relief 16. Of course, the advantages mentioned here also apply to. the cable strain relief 16.
- the special design features are in particular the outer shape of the sheath 2.
- This essentially consists of a circular cylindrical region 22, the outer diameter of which is the same size as or slightly smaller than the diameter of the opening 21.
- the clamping part 6 is also embedded in the cylindrical region 22.
- One end of the cylindrical region also forms one end of the casing 2, while the other end of the cylindrical region merges in steps into a flange-like extension 17 which projects radially with respect to the cylinder axis and to which a truncated cone 26 which tapers with the distance from the extension 17 connects, which forms the other end of the casing 2.
- the cable strain relief 16 with the circular cylindrical region 22 is inserted into the opening 21 from the outside until the extension 17 stops on the housing wall 20. In this situation, the extension transmits 17 the cable strain relief 16 acting tensile forces directed towards the inside of the housing on the housing and ensures the kink and moisture protection.
- a bracket 18 attached to the casing 2 prevents the cable strain relief 16 inserted into the opening 21 as far as it will go, and transmits tensile forces acting on the cable strain relief 16 to the housing, which arise when the cable is pulled from the outside.
- the bracket 18 is bent in a U-shape and its legs are in two mutually parallel, through holes 19 in the casing 2, the distance from each other is equal to the leg distance, which are in a plane perpendicular to the cylinder axis, are arranged on both sides of the cable and which are at a distance from the extension 17 which is approximately equal to the thickness of the housing wall 20.
- the cable strain relief is pushed into the opening 21 until it stops and then the clip 18 is inserted into the holes 19.
- the legs of the bracket 18 are so long that when the base of the clamp 18 lies against the envelope 2, the leg tips protrude from the holes 19.
- the casing 2 of the cable strain relief 30 has some external similarities to that of the cable strain relief 16.
- the casing 2 includes, in particular, a cylindrical region 31 which, in the direction of the cylinder axis, on one side into a truncated cone 32 which tapers with the distance from the cylindrical region and which forms the one end of the casing 2, and on the other side step-like merges into a radially projecting circular extension 33.
- the extension 33 is arranged coaxially with the cylindrical region 31.
- the side wall 38 of the extension 33 facing the cylindrical region 31 overhangs over the cylindrical region 31 and forms an angle of approximately 80 ° with the cylinder axis.
- the opening 21 and the cross section perpendicular to the cylinder axis through the cylindrical region 31 preferably have the same configuration, it being particularly advantageous if the outer contour of the cylindrical region 31 and thus also the opening 21 have a non-round, for example hexagonal, shape.
- the extension 33 is followed by a truncated cone 34 which tapers away from the extension 33 and merges into a cylindrical region 35.
- the end of the cylindrical region 35 facing away from the truncated cone, one end of the cylinder protruding annular bead 37 forms the other end of the sheath 2.
- a narrow annular groove 39 with a circular inner contour is introduced into the outer surface of the cylindrical region 31, which runs in a plane perpendicular to the cylinder axis and whose distance in the direction of the cylinder axis from the side wall 38 (measured at the outer edge facing the annular groove) is equal to the thickness of the housing wall is.
- a "clamp 40 can be anchored in the annular groove 39.
- the clamp 40 is a split washer made of spring steel, the resilient area of which is formed as a cutout from a cylindrical surface oriented perpendicular to the washer.
- the clamp 40 is dimensioned such that it is under Pressure can be pushed into the annular groove 39 and springs back after insertion so that it is firmly anchored in the annular groove 39.
- the clip 40 is inserted only after the cable strain relief 30 with the truncated cone 32 has been inserted from the inside of the housing through the opening in the housing until the extension 33 stops on the housing wall.
- the extension 33 is pressed against the housing wall, the design of the side wall 38 ensuring a particularly good seal and thus further improved moisture protection.
- the extension 31 transmits to the cable strain relief 30 attacking, towards the inside of the housing directed tensile forces on the housing, while the clamp 40 transmits tensile forces acting on the cable strain relief 30 to the housing, which arise when the cable is pulled from the outside.
- the cable strain relief 30 is also secured against rotation about the cylinder axis of the region 31.
- the cable strain reliefs 1 and 16 it is advantageous to use the same non-circular, e.g. B. hexagonal formation of the opening in the housing or the recesses in the housing hood and the lower housing part and on the other hand the area framed by the opening or the recesses of the casing 2.
- the cable strain relief 30 does not require any further precautions for the stable and tight attachment to the housing, apart from the opening 21, which is required anyway.
- the cable strain relief 30 has a clamping part 41 designed as a cylindrical sleeve, the inside diameter of which is approximately equal to the outside diameter of the cable 3.
- the sleeve and thus the cable 3 are pressed together at two points.
- one end of the sleeve is bent over and designed as a vertically projecting flange-like widening 42.
- the axis of the sleeve coincides with the cylindrical axis of the cylindrical region 31, and the sleeve extends out of the truncated cone 32, through the cylindrical region 31 and into the truncated cone 34.
- the sleeve can also be pressed together at only one or at more than two locations, and it is also possible lent that both ends are formed as flange-like widenings.
- the clamping part 41 can be made from the same materials as the clamping part 6. The clamping of the cable 3 in the clamping part 41 and the installation of the clamping part 41 in the sheath 2 is carried out in the same way as has been described above in connection with the clamping part 6.
- the outer contour of the casing 2, including the extension 31 and the annular groove 39 is molded directly onto the cable 3 and the clamping part 41.
