[0001] DEVICE AND METHOD FOR COVERING A CABLE WITH A

[0002] SELF-CLOSING PROTECTIVE HOSE

[0003] Technical area

[0004] The present invention relates to a device and a method for covering a cable with a self-closing protective tube.

[0005] State of the art

[0006] The present invention will be described below mainly in connection with the manufacture of cable assemblies for vehicles.

[0007] A cable in a vehicle's wiring harness can be wrapped with a wrapping tape, at least in sections, to protect the cable from mechanical stress. The wrapping can also bundle multiple cables together to facilitate the wiring harness' installation into the vehicle. The wrapping process can be automated.

[0008] As an alternative to wrapping, the cable can be pulled through a cable protection conduit. The cable protection conduit can be made of a braided material. The cable protection conduit can then be pushed together axially to increase its inner diameter. This allows the cable to be pulled through the cable protection conduit, at least with a small connector. After the cable has been pulled through, the cable protection conduit can be stretched out again to fit the cable protection conduit to the cable.

[0009] For a cable with a large plug, a longitudinally slotted, self-closing

[0010] A protective conduit can be used. To enclose the cable in the self-closing protective conduit, a longitudinal slit in the protective conduit is manually opened and the cable is pushed into an interior space of the protective conduit. The longitudinal slit then closes automatically.

[0011] Description of the invention

[0012] An object of the invention is therefore to provide an improved device and an improved method for enclosing a cable with a self-closing protective sleeve, using the simplest possible design. An improvement in this case may, for example, relate to the automation of a production process and the associated reduction of production costs.

[0013] The object is achieved by the subject matter of the independent claims. Advantageous developments of the invention are specified in the dependent claims, the description, and the accompanying figures.

[0014] A longitudinally slit, self-closing protective sleeve consists of a strip of material that rolls lengthwise into a tube due to pre-tensioning of the material strip. The material of the strip can be a textile material, such as a woven or braided fabric. The rolling process causes the longitudinal edges of the strip to overlap.

[0015] In the approach presented here, a mandrel is inserted from one end of the protective sleeve into an interior space within the sleeve to increase the diameter of the interior space and thus reduce the overlap of the longitudinal edges. To achieve this, the mandrel thickens from a tip until the circumference of the mandrel is larger than the width of the material strip. A slit then opens between the longitudinal edges.

[0016] At the point where the slot opens, a shaft for attaching the mandrel is located. Within the shaft, in the approach presented here, a cable guide is located, which guides a cable from outside the protective sleeve into the expanded interior. After the cable guide, the shaft ends and the mandrel tapers. The longitudinal edges then begin to overlap again, wrapping around the cable inside. Using the approach presented here, a cable can be quickly and easily covered with a self-closing protective sleeve. The protective sleeve is expanded and reclosed in a controlled manner, while the cable is automatically guided into its position inside the interior.

[0017] According to a first aspect of the invention, a device for covering a cable with a self-closing protective hose is presented, wherein the device has a cable guide and a hose guide, wherein the hose guide has a spreading contour and a contact contour, wherein the spreading contour is designed to spread apart two edge regions of the protective hose at a slot running along the protective hose upon a relative movement between the protective hose and the device in order to open a local opening to an interior of the protective hose, the cable guide is designed to insert the cable through a relative movement between the cable and the device through the opening between the spreading contour and the contact contour into the opened interior, and the contact contour is designed to contact the self-closing edge regions against the cable arranged in the interior in order to close the local opening.

[0018] According to a second aspect of the invention, a method for covering a cable with a self-closing protective sleeve using a device according to the first aspect of the invention is presented, wherein two edge regions of the protective sleeve are spread apart at a slot running along the protective sleeve to open a local opening to an interior of the protective sleeve, the cable is inserted through the opening into the opened interior, and the self-closing edge regions are applied to the cable arranged in the interior to close the local opening.

[0019] A cable can be a high-voltage cable. The cable can have one or more electrically insulating sheaths and / or shields. The cable can have one or more cores. The cores can be stranded or wired. The cable can be flexible. Likewise, a group of cables can be sheathed. The cables in the group can be pre-bundled.

[0020] A self-closing protective sleeve can consist of a long strip of material that, due to a pre-tension in the material of the strip, rolls up in a longitudinal direction, forming an elongated hollow space. This hollow space can be referred to as the interior of the protective sleeve. Edge areas of the material strip can overlap. The degree of overlap can influence the diameter of the interior space. The material of the protective sleeve can be, for example, a woven or braided fabric.

[0021] The circumference of the interior space can be enlarged. A spreading contour can enlarge the circumference of the interior space through a wedge effect when the protective sleeve is moved relative to the spreading contour. The relative movement can be generated by a movement of the protective sleeve and alternatively or additionally by a movement of the device. The spreading contour can roll out the material strip at least partially lengthwise. If the circumference of the interior space is larger than a strip width of the material strip, the edge regions of the material strip no longer overlap, and an opening to the interior space is created between two side edges of the material strip. The side edges delimit the edge regions.

[0022] A cable guide can be a guide device for inserting the cable into the expanded interior space. The side edges can be moved apart sufficiently so that the cable guide fits between the side edges. The cable guide can have rollers for guiding or bending the cable. The cable guide can, for example, bend the cable into an S-shape. The cable guide can, in particular, have pairs of rollers arranged on opposite sides of the cable. The rollers of the pairs of rollers can have different diameters.

[0023] A contact contour can reduce the circumference of the interior if the protective sleeve is moved relative to the contact contour. The contact contour can reduce the circumference approximately to the circumference of the cable arranged in the interior. The contact contour can also act on the protective sleeve from the outside. By reducing the circumference, the edges of the material strip in the area of ​​the contact contour can begin to overlap. The contact contour can at least partially roll the material strip lengthwise. The contact contour can cause the protective sleeve to roll in.

[0024] The application contour can be designed to apply the edge areas to the cable one after the other. The application contour can first apply one edge area to the cable and then place the other edge area over the already applied edge area. By applying the edge areas in a defined order, complete encasing of the cable with the protective conduit can be ensured.

[0025] The expansion contour can have a ship's bow-like shape with a leading prow and a stem to separate the edge areas. A leading prow can be arranged in the interior without already expanding the interior. The prow can allow the protective hose to enter the device smoothly. A stem can be the leading edge of a shaft of the expansion contour. The stem can push the side edges of the material strip to the side through direct contact if the protective hose enters the device at an angle.

[0026] The hose guide can have a guide contour for guiding the expanded protective hose from the expansion contour to the contact contour. A guide contour can be an extension of the expansion contour and the contact contour. The guide contour can continue a section of the expansion contour up to the contact contour. The guide contour can provide the necessary space for the cable guide. The guide contour can have a channel for the expanded protective hose. The channel can be formed between an inner part of the cable guide and an outer part of the cable guide. The outer shell can encompass an outer part of the contact contour and guide the expanded protective hose from the outside. The channel can be substantially as wide as the material strip. The channel can be wider than the material strip by a movement tolerance.

[0027] The cable guide can have a lower part connected to the hose guide and an upper part movable relative to the lower part. The cable can be inserted between the upper and lower parts. The lower part can be connected to the hose guide. The upper part can be pivoted or lifted away from the lower part into an open position. The cable can be inserted between the upper and lower parts when the upper part is in the open position. The upper and lower parts can each have one of the rollers of the roller pairs of the cable guide.

[0028] The cable guide can have at least one hold-down device for temporarily securing the cable when the upper part is open. A hold-down device can be a pawl. The hold-down device can be pushed sideways against a spring force by the cable when the cable is inserted between the upper and lower parts. Once the cable is inserted, the hold-down device can spring back. The hold-down device can be arranged in the lower part. The hold-down device can be retracted when the upper part is closed so as not to impede movement of the cable. The cable guide can have several hold-down devices. The hold-down devices can be arranged in the area of ​​the rollers of the cable guide. The hold-down devices can hold the cable in the respective lower roller of the pair of rollers when the cable guide is open. The hold-down devices can in particular be arranged in pairs. The pairs of hold-down devices can each be pushed away by half a cable diameter when the cable is inserted.

[0029] The device can have a cable conveyor for automatically conveying the cable through the cable guide and a hose conveyor for automatically conveying the protective hose through the hose guide. The cable conveyor can be designed to generate the relative movement between the cable and the device. The hose conveyor can be designed to generate the relative movement between the protective hose and the device. The cable conveyor and the hose conveyor can be motor-driven. The cable conveyor and the hose conveyor can be driven in a synchronized manner. The cable conveyor and the hose conveyor can be driven independently of one another. This allows, for example, the protective hose applied to the cable to be moved along the cable. The applied protective hose can also be pushed together on the cable, for example to complete the application at one end of the protective hose.The cable conveyor and the hose conveyor can have driven rollers and / or belts. The rollers can be arranged in pairs on opposite sides of the cable or on the outside and inside of the protective hose. A belt can also be combined with at least one roller on the other side of the material strip of the protective hose.

[0030] The hose conveyor can have two conveyor sections. A cutting device for severing the protective hose can be arranged between the conveyor sections. A front conveyor section can be arranged in the region of the spreading contour. A rear conveyor section can be arranged in the region of the cable guide and / or in the region of the application contour. The conveyor sections can be spaced apart from one another. A cutting device can be arranged in a gap between the conveyor sections. The cutting device can be a hot-wire cutting device and can be designed to sever the protective hose using a heated hot wire or a heated blade. The cutting device can be held ready in a retracted position. To sever the protective hose, the cutting device can be moved between the conveyor sections. The cutting device can also be a conventional cutting device with a blade.In this case, the cutting device can be described as a guillotine. The cutting device allows the protective hose to be kept ready in roll form and cut to the required length.

[0031] The conveyor sections can be controlled independently of each other. The front conveyor section can operate synchronously with the rear conveyor section while the cable is being sheathed. During cutting, the conveyor sections can move in opposite directions, or apply force to the protective sleeve in opposite directions to tension the sleeve between the conveyor sections. This prevents the freshly cut ends of the protective sleeve from fusing together. Likewise, the front conveyor section can be stationary to hold one end of the protective sleeve ready for the next cable, while the rear conveyor section moves the freshly cut end to be applied to the cable currently in the device.

[0038] Detailed description

[0039] Fig. 1 shows a diagram of a device 100 for covering a cable 102. The device 100 is designed to cover the cable 102 with a self-closing protective sleeve. The protective sleeve is not shown here for the sake of clarity. The device 100 shown here is configured as a handheld tool and is designed to be moved in one direction of movement relative to the cable 102 and the protective sleeve using two handles.

[0040] A self-closing protective conduit is a longitudinally rolled strip of material, particularly textile. The material strip is rolled so tightly that the lateral edges overlap significantly. Inside the protective conduit, a longitudinally extending interior space is formed, in which the cable is to be placed.

[0041] The device 100 has a cable guide 104 for the cable 102 and a hose guide 106 for the protective hose. The hose guide 106 has a spreading contour 108 and a contact contour 110. The spreading contour 108 is arranged at a front end of the hose guide 106. The contact contour 110 is arranged at a rear end of the hose guide 106. The cable guide 104 is arranged between the spreading contour 108 and the contact contour 110.

[0042] The spreading contour 108 has a leading protrusion 112 or mandrel. The protrusion 112 is inserted into the interior of the self-closing protective tube. The protrusion 112 expands from a tip. When a diameter of the protrusion 112 is larger than a diameter of the interior, the spreading contour 108 begins to spread the protective tube. The protective tube is spread until the edge regions of the material strip no longer overlap and an opening is created between the side edges of the material strip. The edge regions can no longer overlap where a circumference of the spreading contour 108 is larger than a width of the material strip. At this point, the spreading contour has a stem 114, which pushes itself between the side edges due to the relative movement and deflects them laterally. The stem 114 is a leading edge of a shaft 116 of the hose guide 106.The shaft protrudes through the opening of the spread protective tube from the interior of the protective tube.

[0043] The cable guide 104 is arranged in the area of ​​the shaft 116. The cable guide 104 has several deflection rollers 118 that guide the cable 102 from above through the shaft into the hose guide 106. There, the cable 102 is arranged in the expanded interior of the protective hose.

[0044] The application contour 110 allows the expanded protective hose to wrap itself in a controlled manner around the cable 102 arranged in the interior. For this purpose, the hose guide 106 tapers to its rear end, where the cable 102 exits the device 100.

[0045] Fig. 2 shows a sectional view of a device 100 according to an exemplary embodiment. The device 100 essentially corresponds to the device in Fig. 1. The device 100 is cut through a center plane of the hose guide 106. A guide contour 200 of the hose guide 106 is arranged between the spreading contour 108 and the application contour 110. The guide contour 200 has a channel 202 for the protective hose. The channel 202 begins at a rear end of the spreading contour 108. The spread-open protective hose enters the channel 202 and is guided past the cable guide 104 in the channel 202. The channel 202 is flat and only wider than the material strip of the protective hose by a movement tolerance. Due to its flat shape, the channel 202 prevents the protective hose from spontaneously rolling up. The channel 202 thus guides the spread-open protective hose from an inside and an outside.

[0046] The contact contour 110 is also formed by the channel 202. The inner circumference of the contact contour 110 decreases until the edge areas rest against the cable 102. The channel 202 depicts the rolling movement of the protective conduit three-dimensionally. A radius of the channel 202 perpendicular to the cutting plane becomes increasingly smaller toward the rear end of the contact contour 110.

[0047] In one embodiment, the application contour 110 is asymmetrical. Due to this asymmetry, the channel 202 already has a smaller radius on one side than on the other. As a result, the edge regions are applied to the cable 102 one after the other. The edge region applied second to the cable is placed over the edge region applied first to the cable 102. As a result, the edge regions lie directly on top of one another when the cable 102 exits the rear of the device 100 together with the protective tube.

[0048] Fig. 3 shows an illustration of an automated device 100 according to an exemplary embodiment. The device 100 essentially corresponds to the device in Figures 1 and 2. The device 100 is designed here to enclose the cable 102 with the protective tube 300 in a highly automated manner. The protective tube 300 is shown here only in the expanded state as it enters the channel of the guide contour.

[0049] The device 100 comprises a cable conveyor 302 and a hose conveyor 304. The cable conveyor 302 and the hose conveyor 304 are driven by motors. The cable conveyor 302 has drive rollers 306 that press on the cable 102 from above to automatically move the cable 102 through the cable guide 104. The hose conveyor 304 has drive belts 308 to move the expanded protective hose 300 through the channel. The cable conveyor 302 and the hose conveyor 304 can be controlled independently of one another. This allows the cable 102 to be moved relative to the protective hose 300. The protective hose 300 attached to the cable 102 can thus be moved along the cable 102.

[0050] The cable conveyor 302 is integrated into the cable guide 104 and interacts with the deflection rollers of the cable guide 104. The cable conveyor 302 is arranged in a movable upper part 310 of the cable guide 104. The upper part 310 can be pivoted away to insert the cable 102 into the cable guide 104. A lower part of the cable guide 104 is integrated into the hose guide 106.

[0051] The hose conveyor 304 is arranged in the area of ​​the guide contour and in the area of ​​the contact contour. The drive belts 308 are arranged in pairs on the right and left sides of the channel and press against the spread protective hose 300 through cutouts in the channel. Fig. 4 shows a sectional view of an automated device 100 according to an exemplary embodiment. The device 100 essentially corresponds to the device in Fig. 3. The device 100 is shown here in a section perpendicular to the channel 202.

[0052] The cable conveyor 302 here has five drive rollers 306. The drive rollers 306 are all arranged in the upper part 310 of the cable guide 104. The drive rollers 306 are rubberized and knurled. This ensures that the drive rollers 306 have a high level of grip on the cable 102. Two of the drive rollers 306 are also deflection rollers 118 and each form a pair of rollers with a deflection roller 118 arranged opposite one another in the lower part of the cable guide 104. Another deflection roller 118 is arranged at a rear end of the upper part 310.

[0053] Three hold-down devices 400 are arranged between the drive rollers 306. The hold-down devices 400 each have a spring-loaded locking pawl that is pushed back by the cable 102 when the cable 102 is inserted and springs back again above the cable 102. The hold-down devices 400 are arranged on the lower part of the cable guide 104 and hold the cable 102 in the lower part until the upper part 310 is placed on the lower part and the cable 102 is pressed onto the lower part by the upper part 310. The hold-down devices 400 are then retracted.

[0054] The hose conveyor 304 is divided here into a front hose conveyor 304 and a rear hose conveyor 304. A cutting device 402 for separating the protective hose 300 is arranged between the front and rear hose conveyors 304. The front hose conveyor 304 and the rear hose conveyor 304 are each arranged in a separate cutout 404 in an outer wall of the channel 202.

[0055] The cutting device 402 is arranged in a space between the front hose conveyor 304 and the rear hose conveyor 304. In the area of ​​the space, the guide contour 200 has a slot 406 running perpendicular to the channel 202. The protective hose 300 extends over the slot 406. For cutting, a knife 408 of the cutting device 402 is moved into the slot 406 and cuts the protective hose 300 to length.

[0056] In one embodiment, the cutting device 402 is

[0057] The device is designed as a hot-wire cutting device. The blade 408 is an electrically heated wire or an electrically heated metal strip. The heated blade 408 cuts through the protective tube 300 without the application of significant force. Any vapors generated can be extracted. The blade 408 is tensioned by a spring mechanism to compensate for thermal expansion.

[0058] In one embodiment, the front tube conveyor 304 and the rear tube conveyor 304 can be controlled independently of one another. Thus, the front tube conveyor 304 can be driven against a processing direction, while the rear tube conveyor 304 is driven forward. The drive forces can cancel each other out and tension the protective tube 300 in the space between them. This assists in separating the protective tube 300, and the cut edges of the two parts of the protective tube 300 cannot re-weld.

[0059] In one embodiment, the drive belts 308 are designed as toothed belts. Due to the toothing, the drive belts 308 have no slippage on their pulleys 410 and can be moved synchronously. The drive belts 308 run over several pulleys 410. In the front hose conveyor 304, two pulleys 310 are arranged directly on the channel 202. In the rear hose conveyor 304, three pulleys 410 are arranged directly on the channel 202. Between the pulleys 410 arranged directly on the channel 202, the drive belts 308 run parallel to the outer wall of the channel 202. Suspensions of the pulleys 410 are pressed towards the channel 202 by spring assemblies in order to generate a contact force of the drive belts 308.

[0060] In one embodiment, support rollers 412 are arranged on the opposite side of the channel 202, opposite the pulleys 410 arranged directly on the channel 202, in an inner wall of the channel 202. The protective hose 300 runs between the drive belts 308 running on the pulleys 410 and the support rollers 412. The support rollers 412 support the contact pressure.

[0061] In other words, an insertion slide is presented to facilitate the mounting of open tubes on high-voltage cables.

[0062] Until now, the cables have been inserted into the tube by hand, which is very cumbersome, especially for longer sections, as the tube keeps curling up. When the finger is pulled through the tube to open it, the two relatively rough edges press so hard on the sides of the finger that it becomes painful after just a few centimeters.

[0063] The approach presented here simplifies the insertion of HV cables into open tubes. The consistent contour of the slide also ensures consistent quality.

[0064] The tube, which always tends to return to its original shape when spread open, is forced into a position by the relatively complex contour of the 3D-printed carriage, allowing the cable to be inserted over several pulleys. Once the cable is inserted, the two sides of the tube are laid one after the other over the cable in a defined manner, so that the cable is then completely enclosed by the tube without any overlap.

[0065] In one embodiment, the carriage is moved manually. In another embodiment, the process is automated.

[0066] The carriage presented here enables high assembly speed while making work easier for the operator. The carriage is ergonomically designed. The defined guidance of the cable and tube ensures consistently high quality. The manual process can be automated.

[0067] The carriage has a complex outer contour, resembling a ship's hull from the front. An inner contour overlaps the two side flanks. At least two pairs of pulleys guide the cable.

[0068] During automated sheathing of the pipe, the tube is pushed onto the spreading contour up to the cutting unit in the device's basic position. The conveyor head is in the upper position.

[0069] The beginning of the cable is inserted into the device using a mechanical gripper or by hand. The spring-loaded locks snap into place and hold the cable until the conveyor head is moved into a working position. The tube and cable rollers are then driven until a sensor detects the end of the cable shuts them off. The tube is then cut to the required length. The conveyor head is then moved back to its home position, and the end of the cable is removed using a mechanical gripper or by hand.

[0070] Since the devices and methods described in detail above are exemplary embodiments, they can be modified widely by those skilled in the art without departing from the scope of the invention. In particular, the mechanical arrangements and the relative sizes of the individual elements are merely exemplary.
