Description

[0001] The invention relates to an arrangement according to claim 1 and a method for producing the cable harness according to claim 8.

[0002] From DE 10 2012 217 618 A1 a method for encapsulating a contour-shaped flat conductor is known.

[0003] From JP 6 289 523 B2 a method for producing a wire harness and a device for producing a wire harness are known.

[0004] EP 2 234 120 A2 discloses a mold for producing a cable harness. To prevent foaming of the cables, the mold has a holding device.

[0005] Furthermore, a method for producing a foamed cable harness is known from DE 10 2016 108 522 A1.

[0006] It is an object of the invention to provide an improved shape, an improved arrangement and an improved method for producing a wiring harness.

[0007] This object is achieved by means of an arrangement according to claim 1 and a method according to claim 8. Advantageous embodiments are specified in the dependent claims.

[0008] An improved arrangement can be provided in that the arrangement has a mold and a router clip. The mold has a fastening device and at least one first mold part arranged on the fastening device. The fastening device has a holding element and a fastening part, wherein the fastening part has a clip receptacle for partially receiving a router clip of the cable harness and a holding element receptacle. The holding element receptacle is aligned at an angle to the clip receptacle and opens into the clip receptacle. In the holding element receptacle, the holding element is arranged displaceably between an unlocking position and a locking position different from the unlocking position. In the locking position, the holding element projects into the clip receptacle with an engagement section. In the unlocking position, the engagement section is arranged substantially in the holding element receptacle.The router clip has a cable holder with an encompassing section and a fastening section connected to the cable holder. The cable holder is arranged at least in section in the molding space. Furthermore, the fastening section is arranged at least in section in the clip receptacle. The fastening section of the router clip has at least one locking element. With the locking element, the router clip can be fastened, for example, to a component of a vehicle, for example to a body element. The locking element can be designed, for example, as a locking lamella. In the locking position of the holding element, the holding element projects with the engagement section into the clip receptacle and the locking element engages behind the engagement section. In the unlocking position, the engagement section is arranged laterally offset from the locking element.The engagement section is preferably located at least partially in the holding element receptacle of the fastening part.

[0009] By engaging the locking element behind the engagement section, the position of the router clip can be secured by the fastening device. In particular, the position of the cable holder in the mold cavity can be fixed particularly reliably. In particular, unintentional pulling out of the mold during routing is prevented.

[0010] This design has the advantage that, in the locking position, a locking element of the locking portion can engage behind the engagement portion of the retaining element, allowing the router clip to be held in place particularly easily by means of the fastening device. In the unlocking position, the retaining element releases the locking element in the clip receptacle due to the retracted or countersunk engagement portion, and is no longer held in the clip receptacle by the engagement portion.

[0011] In a further embodiment, the retaining element receptacle extends along a first straight line. The retaining element is pin-shaped and extends along the first straight line. The engagement portion is arranged adjacent to a second end of the retaining element. This allows the retaining element to be particularly short. Furthermore, the actuating device can be particularly short in the transverse direction.

[0012] In a further embodiment, the mold cavity extends along a main direction of extension. The retaining element is inclined, preferably perpendicular, to the main direction of extension. This configuration has the advantage that the retaining element can be actuated particularly easily from the side of the mold, thus ensuring a high level of operating convenience. Furthermore, the retaining element can also be actuated automatically, for example, by a manipulator, and can be moved between the locking position and the unlocking position.

[0013] In a further embodiment, a sealing element is arranged between the fastening part and the first molded part, wherein the sealing element at least partially seals the clip receptacle from the molding cavity. The sealing element can preferably be designed as a surface seal. This configuration has the advantage that a liquid first material and / or a liquid first precursor for producing the first material and / or a mixture of a first precursor and a second precursor for producing a sheathing of the cable harness cannot penetrate from the molding cavity into the clip receptacle. This ensures that the holding element can move between the locking position and the unlocking position.

[0014] In a further embodiment, the fastening part has a mold receptacle on the side facing the mold cavity, wherein the mold receptacle is designed to correspond at least in sections to the first molded part. The first molded part is arranged in the mold receptacle, wherein the mold cavity extends over the first molded part and the fastening part. This embodiment has the advantage that the position of the first molded part relative to the fastening part can be determined in at least one spatial direction by the arrangement of the first molded part in the mold receptacle, thereby ensuring a preferably continuous course of the mold cavity over the first molded part and the fastening part. This can ensure continuous production of the cable harness in the region of the first molded part and the first fastening part.

[0015] In a further embodiment, the first molded part has a receptacle on a side facing the fastening part, which is preferably groove-shaped. The receptacle extends at an angle to a main extension direction of the molding space. The fastening part has an engagement web that engages in the receptacle and positively connects the fastening part to the first molded part at least in the main extension direction. This configuration has the advantage that unintentional levering of the first molded part relative to the fastening part can be avoided when inserting cables into the molding space or when inserting the router clip into the first molded part and the fastening part.

[0016] In a further embodiment, the fastening part comprises at least one of the following second materials: polyethylene, polypropylene, or polytetrafluoroethylene. The holding element comprises at least one of the following third materials: polyethylene, polypropylene, polytetrafluoroethylene, metal, stainless steel, rust-proof steel, aluminum, or VA steel. This configuration has the advantage that adhesion of material for producing the sheath to the fastening part and / or to the holding element can be avoided. Furthermore, reliable sliding of the holding element in the fastening part is ensured.

[0017] An improved method for producing a cable harness can be provided by providing a mold configured as described above. The holding element is moved into the unlocked position, and in the unlocked position, the fastening section of the router clip is inserted into the clip receptacle. The holding element is moved into the locked position, and a locking element of the fastening section is engaged behind by the holding element. This configuration has the advantage that the router clip can be particularly well secured in the mold.

[0018] In a further embodiment, an electrical cable is inserted into the mold cavity to form a cable bundle in such a way that the cable is encompassed by the cable holder and held in the mold cavity. A liquid first material and / or a first precursor of the first material and / or a mixture of a first precursor and a second precursor of the first material is introduced into the mold cavity. The liquid first material and / or the liquid first precursor and / or the mixture of the liquid first and second precursor of the first material flows around the cable holder and the electrical cables, at least in sections. The liquid first material and / or the liquid first precursor and / or the mixture of the first precursor and the second precursor is cured to form a sheath for the cable harness.After at least some of the liquid first material and / or the liquid first precursor and / or the liquid mixture of the first and second precursors has hardened, the retaining element is moved from the locking position to the unlocking position. The cable harness is removed from the mold with the router clip by removing the fastening section from the clip receptacle.

[0019] It is particularly advantageous if the fastening section, preferably laterally, is guided past the retaining element in the unlocked position without the fastening section striking the retaining element. This results in particularly low assembly forces for installing the router clip in the mold.

[0020] In a further embodiment, the liquid first material and / or the liquid first precursor and / or the liquid mixture of the first precursor and second precursor is only introduced into the mold cavity when the retaining element is in the locking position and the router clip is secured in the mold. The cables are also already inserted into the mold cavity and the cable holder before the liquid first material and / or the liquid first precursor and / or the mixture of the first and second precursor is introduced.

[0021] The invention is explained in more detail below with reference to the figures. These show: Fig. 1 a schematic representation of a section of a wiring harness; Fig. 2 a schematic sectional view along a Fig. 1 shown section plane AA through the Fig. 1 wiring harness shown; Fig. 3 a schematic representation of an arrangement with a mold for producing the Fig. 1 and Fig. 2 wiring harness shown; Fig. 4 a sectional view along a Fig. 3 shown section plane BB through the Fig. 3 arrangement shown; Fig. 5 a partially transparent representation of the Fig. 3 and Fig. 4 shown arrangement; Fig. 6 is a flowchart of a method for manufacturing the wire harness; and Fig. 7 a sectional view along the Fig. 3 shown section plane BB through the Fig. Arrangement shown in Figure 3.

[0022] For ease of understanding, the following figures refer to a coordinate system. The coordinate system is designed as a right-handed system and has an x-axis (longitudinal direction), a y-axis (transverse direction), and a z-axis (height direction).

[0023] Fig. 1 shows a schematic representation of a section of a wiring harness 10.

[0024] The wiring harness 10 is installed in a vehicle 15, in particular in a motor vehicle. The wiring harness 10 comprises a cable bundle 20, a sheath 40, and a router clip 50. The cable bundle 20 comprises a plurality of electrical cables 25 extending in the longitudinal direction (x-direction). The electrical cables 25 run substantially parallel to one another. Each of the electrical cables 25 has an electrical conductor 30 and a cable insulation 35, wherein the cable insulation 35 is arranged circumferentially around the corresponding electrical conductor 30 and electrically insulates the electrical conductor 30.

[0025] The electrical cable 25 can be configured for transmitting data signals and / or electrical power. The electrical cable 25 can also be configured as a shielded cable 25, so that shielding can be provided circumferentially around the electrical conductor 30 configured for data or power transmission. One or more cables 25 can also be twisted together in a spiral pattern and run within the cable bundle 20, for example, as a twisted-pair cable.

[0026] The cable bundle 20 is embedded in the sheath 40 of the cable harness 10. The sheath is in Fig. 1 is shown transparently. The sheath 40 connects the individual electrical cables 25 to one another in a materially bonded manner, at least in sections. The sheath 40 can comprise a first material which in particular comprises a foam material. The foam material can be closed-pore, open-pore, or mixed-pore. In particular, the sheath can comprise polyurethane or silicone as the first material. In the embodiment, the sheath 40 has, for example, a substantially rectangular outer contour 45. The outer contour 45 of the sheath 40 can, however, also be circular, elliptical, or trapezoidal. In the embodiment, the cable bundle 20 is arranged in the sheath 40 such that the cable bundle 20 is guided in the sheath 40 at a distance from the outer contour 45.

[0027] The router clip 50 is, for example, formed as a single piece and made of the same material. It is particularly advantageous if the router clip 50 comprises a cable holder 55 and a fastening section 60 connected to the cable holder 55 (essentially in Fig. 1). The fastening section 60 and the cable holder 55 mechanically fix the cable bundle 20 in the vehicle 15.

[0028] Fig. 2 shows a schematic sectional view along a Fig. 1 shown section plane AA through the Fig. 1 wiring harness 10.

[0029] The cable holder 55 has a surrounding section 70. The surrounding section 70 is connected to the fastening section 60. The surrounding section 70 circumferentially encloses a receiving space 75 in the y- and z-directions, wherein the cable bundle 20 of the cable harness 10 runs in the receiving space 75 and is encompassed in the circumferential direction by the surrounding section 70. The receiving space 75 is open in both longitudinal directions, so that the cable bundle 20 with the electrical cables 25 can pass through the receiving space 75.

[0030] On the upper side, the cable holder 55 has an insertion opening 80 on a side facing away from the fastening section 60, wherein the insertion opening 80 opens into the receiving space 75. Because the router clip 50 is embedded in the sheath 40, particularly in the region of the encompassing section 70, the sheath 40 prevents the insertion opening 80 from being opened unintentionally.

[0031] In the partially assembled state of the router clip 50, i.e., in particular, when the router clip 50 is not yet embedded in the sheath 40, the insertion opening 80 can be widened by an elastically reversible deformation of the encompassing section 70. For this purpose, the closure region 85 can be bent about a bending axis 90 into the receiving space 75 or away from the receiving space 75 by at least 45°, so that the insertion opening 80 is widened, and the electrical cable 25 of the cable bundle 20 can be inserted individually or several cables 25 at once into the receiving space 75 from above, i.e., in the z-direction opposite the fastening section 60, along a movement that runs essentially parallel to the z-axis.

[0032] The fastening section 60 can, for example, have one or more locking elements 95. The locking element 95 serves, when the wiring harness 10 is mounted in the vehicle 15, to engage behind an opening of a component of the vehicle 15, for example, a body component of the vehicle 15, and to fasten the router clip 50 to the body component. The locking element 95 can be designed as a locking lamella. The wiring harness 10 is also fastened to the body component of the vehicle 15 by means of the router clip 50.

[0033] Fig. 3 shows a schematic representation of an arrangement 195 with a mold 200 for producing the Fig. 1 and Fig. 2 shown wiring harness 10.

[0034] In addition to the mold 200, the assembly 195 also includes the router clip 50 of the wiring harness 10. The mold 200 has at least one first mold part 205. In addition, the mold 200 can have a second mold part 210 and preferably at least one third mold part 215. In addition, the mold 200 has at least one fastening device 220. In particular, the mold 200 can have a plurality of fastening devices 220 arranged spaced apart from one another in the longitudinal direction.

[0035] In the embodiment, the mold 200 is designed, for example, as an open mold 200. The mold 200 is fastened to a mounting board 225, which extends, for example, in an xy plane. The mold 200 is designed to be open on a side opposite the mounting board 225 in the z direction. The arrangement of a cover on the mold 200 is omitted in the embodiment, for example. The mold 200 delimits a mold space 230 in the transverse direction and downwards in the z direction. The mold space 230 extends essentially in the longitudinal direction.

[0036] The Fig. However, the exemplary embodiment of the form 200 shown in Figure 3 can also be different from that shown in Fig. 3. In particular, contrary to the rectilinear configuration of the molding space 230 extending substantially along the x-direction, the mold 200 may also have a different type of molding space 230, for example, one that extends in a curved manner.

[0037] The fastening device 220 is arranged in the longitudinal direction, for example, between the second molded part 210 and the third molded part 215. The second and third molded parts 210, 215 can have a cross-section that is substantially constant in the longitudinal direction. In particular, Fig. 3 the geometric design of the mold space 230 of the second and third mold parts 210, 215 is identical in the longitudinal direction.

[0038] The fastening device 220 has a fastening part 235. The fastening part 235 has a mold receptacle 240. The mold receptacle 240 is arranged in the longitudinal direction between a first end face 245 of the fastening part 235 and a second end face 250. At the first end face 245, the second mold part 210 preferably bears fluid-tight against the fastening part 235. Opposite in the longitudinal direction, at the second end face 250, the third mold part 215 preferably bears fluid-tight against the second end face 250. The fastening part 235 likewise delimits the mold space.

[0039] The mold receptacle 240 is arranged at a distance from the first and second end faces 245, 250 and is configured to correspond to the first mold part 205. In this embodiment, the first mold part 205 is arranged in the mold receptacle 240. The configuration of the mold receptacle 240 is, for example, such that a first upper side 255 of the first mold part 205 is arranged substantially in a common plane with a second upper side 260 of the fastening part 235.

[0040] The molding space 230 extends beyond the fastening part 235 and the first mold part 205. The first mold part 205 delimits a molding space section 265 of the molding space 230. For example, the molding space section 265 is widened in the transverse direction in some regions in the first mold part 205 and is wider than, for example, in the second mold part 210 and / or the third mold part 215. In the molding space section 265, a contour of the molding space 230 is selected such that the router clip 50 is arranged at a distance from at least one lateral wall 270, 275 of the first mold part 205.

[0041] Furthermore, a holding element receptacle 280 is arranged in the fastening part 235. The holding element receptacle 280 is arranged at a distance in the z-direction from the mold cavity 230 and the mold receptacle 240. The holding element receptacle 280 extends, for example, substantially in the transverse direction and opens at least at a first side surface 285 of the fastening part 235. The holding element receptacle 280 can, for example, have a circular, oval, elliptical, rectangular, or polygonal cross-section. The holding element receptacle 280 extends rectilinearly, preferably parallel to the y-axis. Thus, the holding element receptacle 280 is arranged inclined to a main extension direction (longitudinal direction) of the mold cavity 230. Furthermore, the holding element receptacle 280 is arranged at a distance in the z-direction from the molding space 230 such that neither the molding space 230 opens into the holding element receptacle 280 nor the holding element receptacle 280 opens into the molding space 230.

[0042] The first side surface 285 can extend between the second upper side 260, which is configured, for example, as an xy plane, and a first lower side 290 of the fastening part 235. The first side surface 285 can be flat.

[0043] The holding element receptacle 280 is arranged on the underside in the z-direction between the mold receptacle 240 and the first underside 290. In particular, for example, the holding element receptacle 280 is arranged overlapping the mold receptacle 240 in the z-direction. Overlapping in the z-direction means that when two components are projected along the z-axis in the z-direction into a projection plane, which is configured, for example, as an xy-plane and oriented perpendicular to the projection direction, the two components, for example the holding element receptacle 280 and the mold receptacle 240, overlap in the projection plane.

[0044] Fig. 4 shows a sectional view along a Fig. 3 shown section plane BB through the Fig. 3 shown arrangement 195.

[0045] The first mold part 205 and the fastening part 235 together define a clip receptacle 295. The clip receptacle 295 opens into the mold cavity 230 at the top, on the side facing the insertion opening 80. The clip receptacle 295 extends, for example, between the mold cavity 230 and the first underside 290. The clip receptacle 295 can, for example, be tapered from the first underside 290 toward the mold cavity 230. The router clip 50 engages the clip receptacle 295 with the fastening section 60.

[0046] In addition to the fastening part 235, the fastening device 220 has a holding element 305. The holding element 305 is arranged at least partially in the holding element receptacle 280. The holding element receptacle 280 and the holding element 305 extend along a first straight line 310. The first straight line 310 can be aligned parallel to the y-axis. Thus, the holding element 305, but also the holding element receptacle 280 and the first straight line 310, are aligned at an angle to a main extension direction (longitudinal direction) of the molding space 230, but also of the cable harness 10.

[0047] The fastening part 235 comprises at least one of the following second materials: polyethylene, polypropylene, polytetrafluoroethylene. The holding element 305 comprises at least one of the following third materials: polyethylene, polypropylene, polytetrafluoroethylene, metal, stainless steel, rust-proof steel, aluminum, or stainless steel.

[0048] An outer peripheral side 315 is configured to correspond to an inner peripheral side 320 of the retaining element receptacle 280. The retaining element receptacle 280 is configured as a through-opening and extends transversely between the first side surface 285 of the fastening part 235 and the clip receptacle 295. In particular, the retaining element receptacle 280 opens into the clip receptacle 295. It is particularly advantageous if the retaining element receptacle 280 is arranged in the fastening part 235 at a distance in the z-direction from both the mold space 230 and the first underside 290.

[0049] Furthermore, a sealing element 325 is arranged in the z-direction between the first mold part 205 and the fastening part 235. The sealing element 325 can, for example, be substantially plate-shaped. Furthermore, the sealing element 325 at least partially delimits the clip receptacle 295 in the transverse direction. The sealing element 325 is arranged, for example, in the z-direction between the first mold part 205 and the fastening part 235. In this case, the sealing element 325 is designed, for example, such that the sealing element 325 seals the clip receptacle 295 against the mold space 230 at the fastening section 60.

[0050] The holding element 305 is arranged to be displaceable between an unlocking position and a locking position along the first straight line 310. Fig. 4 shows the retaining element 305 in the unlocked position by way of example. In the unlocked position, the retaining element 305 preferably protrudes with an actuating portion 330 beyond the first side surface 285 of the fastening part 235. The actuating portion 330 adjoins, for example, a first end of the retaining element 305.

[0051] Transversely opposite the first end of the holding element 305, the holding element 305 has an engagement portion 335. The engagement portion 335 adjoins a second end of the holding element 305. The second end is arranged transversely opposite the first end. In the transverse direction, a connecting portion 340 connects the actuating portion 330 to the engagement portion 335. A profile of the holding element 305 can be identical along the first straight line 310 across the engagement portion 335, the actuating portion 330, and the connecting portion 340.

[0052] The first mold part 205 has a first wall 270, a second wall 275, and a base section 355. In the transverse direction, the first wall 270 is arranged opposite the second wall 275, wherein in the transverse direction the first wall 270 and the second wall 275 delimit the mold cavity 230. On the underside, the first wall 270 and the second wall 275 are connected to one another via the base section 355. The base section 355 delimits the mold cavity 230 on the underside. Furthermore, the clip receptacle 295 extends through the base section 355 between the sealing element 325 and the mold cavity 230. The base section 355 forms a mold base 360 ​​of the mold cavity 230.

[0053] When the router clip 50 is inserted into the mold space 230, the fastening section 60 engages the clip receptacle 295. Furthermore, the cable holder 55 preferably sits on the underside of the mold base 360.

[0054] Fig. 5 shows a partially transparent representation of the Fig. 3 and Fig. 4 shown arrangement 195.

[0055] In this case, Fig. 5 the first molded part 205 is transparent and the other components are shown in the arrangement 195 as non-transparent.

[0056] The first molded part 205 has, for example, a receptacle 380 on the side facing the fastening part 235. The receptacle 380 extends essentially along the first straight line 310 between the first side surface 285 and a second side surface 385 of the fastening part 235 arranged transversely opposite the first side surface 285. The receptacle 380 is, for example, groove-shaped in the first molded part 205. The receptacle 380 is, for example, shorter in the longitudinal direction than a maximum longitudinal extent of the first molded part 205. The receptacle 380 is, for example, wider than the clip receptacle 295 and the router clip 50. In the longitudinal direction, the receptacle 380 can be formed in a central position relative to the maximum longitudinal extent of the first molded part 205.

[0057] The fastening part 235 has an engagement web 390, wherein the engagement web 390 is configured to extend transversely along the first straight line 310. The engagement web 390 is configured in the longitudinal direction substantially corresponding to a longitudinal extension of the receptacle 380. The sealing element 325 is arranged on the upper side between a groove base 395 of the receptacle 380 and the engagement web 390. The sealing element 325 is configured, for example, as a surface seal. The holding element receptacle 280 is arranged, for example, at least in sections in the engagement web 390.

[0058] By engaging the engagement web 390 in the receptacle 380, the first molded part 205 is positively connected to the fastening part 235 in the longitudinal direction. In particular, this reliably prevents movement of the first molded part 205 relative to the fastening part 235 in the longitudinal direction.

[0059] To prevent movement of the first mold part 205 relative to the fastening part 235 in the y-direction and z-direction, the mold 200 has, for example, a fastening means 396. The fastening means 396 can be designed, for example, as a screw connection. Another configuration of the fastening means 396 would also be possible.

[0060] In the embodiment, the fastening means 396 is arranged in the longitudinal direction between the receptacle 380 and a third end face 397 of the first molded part 205. With the third end face 397, the first molded part 205 rests against the mold receptacle 240 of the fastening part 235. In the longitudinal direction opposite the third end face 397, a further fastening means 396 can be arranged between the engagement of the engagement web 390 in the receptacle 380 and a fourth end face 398 of the first molded part 205 in order to fasten the first molded part 205 to the fastening part 235 and to prevent displacement of the molded part 205 relative to the fastening part 235. The fourth end face 398 is aligned, for example, in the x-direction parallel to the third end face 397 and is arranged opposite the third end face 397 in the longitudinal direction.

[0061] It is also particularly advantageous if the first molded part 205 and the fastening part 235 are flush and flat on the top side. This prevents the cables 25 from getting caught on the first molded part 205 when routing.

[0062] Fig. 6 shows a flowchart of a method for manufacturing the wiring harness 10. Fig. 7 shows a sectional view along the Fig. 3 shown section plane BB through the Fig. 3, wherein the holding element 305 is in the locking position.

[0063] In a first method step 400, the mold 200 and the router clip 50 are provided.

[0064] In a second method step 405 following the first method step 400, the holding element 305 is moved into the unlocking position on the actuating portion 330. In the unlocking position, the engagement portion 335 preferably does not protrude into the clip receptacle 295, but is retracted, preferably completely, into the holding element receptacle 280. In the unlocking position, the actuating portion 330 can protrude beyond the first side surface 285.

[0065] In a third method step 410 following the second method step 405 (cf. Fig. 4 and Fig. 5) The router clip 50 is mounted in the mold 200, thereby forming the arrangement 195. In this case, the router clip 50 is inserted into the mold cavity 230 via the insertion opening 80 along a second straight line 365, which runs parallel to the z-axis. The router clip 50 is inserted into the mold cavity 230 and, with the fastening section 60, into the clip receptacle 295 along the second straight line 365, so far that the fastening section 60 is preferably arranged completely in the clip receptacle 295. The cable holder 55 is then located in the mold cavity 230 and sits on the underside of the mold base 360.

[0066] If the mold 200 has a plurality of fastening devices 220, a router clip 50 is inserted into each of the plurality of fastening devices 220 in the third method step 410.

[0067] In a fourth method step 415 following the third method step 410 (cf. Fig. 7), the retaining element 305 is moved from the unlocking position along the first straight line 310 into the locking position. In doing so, the retaining element 305 is displaced in the direction of the clip receptacle 295 in the retaining element receptacle 280. The retaining element receptacle 280 preferably guides the retaining element 305 with the inner peripheral side 320.

[0068] In the locked position, the holding element 305 extends with the engagement section 335 into the clip receptacle 295. The actuating section 330 engages behind the holding element 305 at the engagement section 335 with locking elements 370, so that an unintentional withdrawal of the router clip 50 in the z-direction out of the forming space 230 away from the holding element 305 is prevented by the engagement of the locking elements 370. This ensures a secure hold of the router clip 50, in particular of the cable holder 55, in the forming space 230.

[0069] The second to fourth method steps 405 to 415 are also repeated for further router clips 50 to be inserted into the mold 200 on further fastening devices 220.

[0070] In a fifth method step 420 following the fourth method step 415, the electrical cables 25 of the cable bundle 20 are inserted into the molding chamber 230 and into the receiving space 75 of the cable holder 55. The cable holder 55 secures the inserted electrical cables 25 of the cable bundle 20 in the molding chamber 230, preventing the electrical cables 25 from accidentally escaping from the molding chamber 230. This ensures secure insertion of the cables 25 of the cable bundle 20 into the upwardly open molding chamber 230.

[0071] In a sixth method step 425 following the fifth method step 420, the liquid first material and / or a liquid first precursor, or a mixture of the first precursor and a second precursor is introduced into the molding cavity 230. In particular, the liquid first material and / or the liquid first precursor, or the mixture, is applied to the top of the cable bundle 20 and the router clip 50.

[0072] The liquid first material and / or the liquid first precursor, or the mixture, is preferably thin-bodied. A curing time of the first material and / or the liquid first precursor, or the mixture, is selected such that sufficient time is available for the liquid first material and / or the liquid first precursor, or the mixture, to seep into the mold cavity 230 toward the mold base 360 ​​and / or to enter the receiving space 75.

[0073] It is particularly advantageous, for example, if the first liquid material and / or the liquid first precursor, or the mixture, is mechanically and / or chemically foamed. The first material and / or the liquid first precursor, or the mixture, particularly during foaming, encloses the cable bundle 20 and the cable holder 55 surrounding the cable bundle 20. As a result, the cable holder 55 and the cable bundle 20 are at least partially, preferably substantially completely, embedded in the first material and / or the liquid first precursor, or the mixture.

[0074] During or after foaming, the first material, the first liquid material and / or the liquid first precursor, or the mixture is cured to form the foam material of the sheathing 40. The first material and / or the liquid first precursor or the mixture forms a material-to-material bond both with the individual electrical cables 25 of the cable bundle 20 and with the cable holder 55 of the respective router clip 50.

[0075] The sealing element 325 prevents the liquid first material and / or the liquid first precursor, or the mixture from the molding space 230 from entering the clip receptacle 295, in particular in an area in which the engagement portion 335 protrudes into the clip receptacle 295, in order to ensure the functionality of the fastening device 220.

[0076] In a seventh method step 430 following the sixth method step 425, the cable harness 10 moves the holding element 305 in the molding space 230 from the locking position into the unlocking position by means of the actuating section 330, so that the engagement section 335 is located, preferably completely, in the holding element receptacle 280 (cf. Fig. 4).

[0077] In an eighth method step 435 following the seventh method step 430, the cable harness 10 is removed from the mold cavity 230 by pulling the cable harness 10 upward in the z-direction. The path for the fastening section 60 in the clip receptacle 295 is thereby cleared upward by the retaining element 305 recessed into the retaining element receptacle 280. The manufacturing process is concluded with the eighth method step 435.

[0078] In order to mount the cable harness 10 in the vehicle 15, the fastening section 60 is inserted into a fastening opening of a component of the vehicle 15, wherein the locking element 370 comes to rest behind the fastening opening and engages behind the component in sections.

[0079] Through the Fig. 2 to 5 and 7, the router clip 50 can be particularly easily, preferably fully automatically, fastened in the mold 200. Furthermore, the mold 200 is particularly well suited for a plurality of fastening devices 220, each of which holds a router clip 50, so that even a complex cable harness 10 can be produced using the mold 200.

[0080] The transversely displaceable design of the retaining element 305 in the retaining element receptacle 280 ensures high durability of the fastening device 220 and a long service life. This allows the cable harness 10 to be manufactured particularly cost-effectively.

[0081] Likewise, very easy demolding of the mold 200 and removal of the manufactured cable harness 10 from the mold 200 is ensured by means of the fastening device 220. In particular, no further mechanical devices are necessary for this purpose.

[0082] Furthermore, it is also ensured that when inserting the electrical cables 25 into the router clips 50 and when unintentionally pulling in the z-direction on the cables 25 to be inserted or on the cables already inserted, unintentional removal of the router clips 50 from the forming space 230 is avoided.

[0083] To produce the fastening device 220, preferably by injection molding, the geometry of the fastening device 220 can also be easily adapted to the respective cable harness 10 to be produced. By fixing the router clip 50 by means of the holding element 305 and the clip receptacle 295, which is preferably significantly larger than the fastening section 60, the router clip 50 can be reliably held in the mold cavity 230 by means of the holding element 305. In particular, a cross-section of the fastening section 60 can be varied as a result.

[0084] Furthermore, after producing a cable harness 10 with a first geometry, the fastening device 220 can be mounted with the first mold 200 on a second molded part 210, which has a different geometry than the first molded part 205. This enables recycling of the fastening device 220 and long-term use of the fastening device 220 in the production of a variety of cable harnesses. The fastening device 220 is therefore particularly suitable for molds 200 designed according to the modular principle.
