Description

[0001] The invention relates to a holder according to claim 1 and a molding system according to claim 11.

[0002] A mold for producing a cable harness is known from DE 10 2016 108 522 A1.

[0003] It is an object of the invention to provide a holder for a mold for producing a wire harness and an improved molding system for producing the wire harness.

[0004] This object is achieved by means of a holder according to claim 1 and a molding system according to claim 11. Advantageous embodiments are specified in the dependent claims.

[0005] An improved holder for a mold for producing a wiring harness can be provided in that the holder has at least one closure section and a receiving section. The receiving section adjoins the closure section in a direction of an insertion axis. The receiving section encloses a first holding space at least in sections on the circumference. The closure section has a first insertion opening which extends along the insertion axis and opens into the first holding space. The closure section is elastically reversibly deformable between a first mold state and a second mold state which is different from the first mold state. In the first mold state, the closure section closes the first insertion opening. In the second mold state, the first insertion opening is widened compared to the first mold state and the first holding space is accessible.

[0006] This design has the advantage that, in the second molding state, a cable can be introduced into the holding space by means of the elastically reversibly adjustable closure section, and in the first molding state, the cable inserted into the holding space is held in the first holding space.

[0007] In a further embodiment, the closure section is relaxed in the first molded state. In the second molded state, the closure section is tensioned relative to the first molded state. The closure section automatically returns from the second molded state to the first molded state. This eliminates the need for additional actuation means.

[0008] In a further embodiment, in the second molding state, the closure section is compressed at least partially adjacent to the first insertion opening. This configuration has the advantage that the cable can also be inserted into the receiving space automatically. Furthermore, the cable can be inserted into the receiving space even when the receiving space is almost completely filled.

[0009] In a further embodiment, the closure section has at least one closure body and a first closure element connected to the closure body at a first fixed end, wherein the first closure element extends inclined, preferably perpendicular, to the insertion axis in the first shaped state, wherein the first closure element delimits the first insertion opening at a first free end. In the first shaped state, the first closure element closes the insertion opening at least in sections. This configuration has the advantage that, in particular, the closure section can be bar-shaped and / or tapered from the fixed end to the free end. This configuration is particularly suitable for deforming the closure section particularly easily in order to deform the closure section between the first and the second shaped state.

[0010] It is particularly advantageous if, in the second molded state, the first closure element is bent by at least 50°, preferably by at least 70°, about a first bending axis toward the first holding space or away from the first holding space. The first bending axis is inclined, preferably perpendicular, to the insertion axis. This configuration has the advantage that the first closure section can be deformed particularly easily.

[0011] In a further embodiment, the first holding space is polygonal, wedge-shaped, conical, rectangular, and / or oval. These different shapes are particularly well-suited to avoiding an undercut, allowing the holder to be demolded particularly easily. Furthermore, the aforementioned shapes of the holding space can easily influence the shape of a cable bundle. The shape of the cable bundle ensures that a defined material thickness of the sheath is achieved that is sufficient to withstand the load on the cable harness.

[0012] In a further embodiment, the first insertion opening is slit-shaped. Additionally or alternatively, the first insertion opening can be tapered at least in sections, starting from the first side surface and reaching the first holding space. Additionally or alternatively, the first insertion opening can have a substantially constant width along the insertion axis in the first molded state.

[0013] In a further embodiment, the holder has a further receiving section and a further closing section, wherein the further receiving section has a third holding space and the further closing section has a constriction. The further receiving section is arranged on the side of the first holding space facing away from the closing section and is offset from the first holding space. The further closing section is arranged between the receiving section and the further receiving section and connects the first holder space to the third holding space. This configuration has the advantage that the first holding space and the third holding space can be designed to be slim in the transverse direction, thus allowing the cable harness to be demolded from the holder with low tensile force.

[0014] In a further embodiment, the further closure section is elastically and reversibly deformable between a third shaped state and a fourth shaped state that is different from the third shaped state. In the third shaped state, the further closure section, with the constriction, essentially closes the third holding space from the first holding space. This reliably prevents cables inserted into the third holding space from slipping out into the first holding space. In the fourth shaped state, the constriction is widened compared to the third shaped state, and the first holding space is connected to the third holding space via the constriction. This configuration has the advantage that, in the fourth shaped state, cables can be moved between the first holding space and the third holding space.

[0015] In a further embodiment, the receiving section encloses a second holding space on its circumference. The second holding space is arranged at an angle to the insertion axis and offset from the first holding space. The closure section has a second insertion opening which extends along the insertion axis and opens into the second holding space. The closure section is elastically and reversibly deformable between the first shaped state and a fifth shaped state which is different from the first shaped state. The fifth shaped state is likewise different from the second shaped state. In the first shaped state, the closure section closes the second insertion opening. In the fifth shaped state, the second insertion opening is wider than in the first shaped state.This design has the advantage that the cables can be routed transversely offset from one another in both the first and second holding spaces, allowing for particularly good foam encapsulation. Furthermore, demolding is particularly easy, as the cables do not have to be bundled into a particularly wide cable bundle in the transverse direction.

[0016] An improved molding system for producing a cable harness can be provided in that the molding system has a holder as described above and at least one first mold. The first mold defines a molding chamber, at least in sections. The holder is arranged on the first mold. The first holding chamber directly adjoins the molding chamber. This configuration has the advantage that, by means of the holder, cables that are inserted into the molding chamber and are also inserted into the holding chamber can be reliably fastened in the molding chamber. In particular, this prevents foaming of the cables during overmolding with a sheath, in particular during foaming of the sheath.

[0017] In a further embodiment, the mold system comprises a second mold and a connecting means. The first mold has a first end face facing the second mold, and the second mold has a second end face facing the first mold. The connecting means comprises at least one engagement element and an engagement element receptacle. The engagement element is arranged on the first end face of the first mold. The engagement element receptacle opens at the second end face and is designed to correspond, at least in sections, to the engagement element. The engagement element engages in the engagement element receptacle and connects the first mold to the second mold in a form-fitting manner. This configuration has the advantage that unintentional slipping of the first mold relative to the second mold, in particular in a transverse direction or in a vertical direction, can be reliably prevented.

[0018] It is particularly advantageous if the holder is arranged between the first mold and the second mold. The holder has at least one through-opening configured to correspond to the engagement element. The through-opening extends through the holder. The engagement element passes through the through-opening and fastens the holder to the mold in a form-fitting manner, at least in the direction of the insertion axis. This configuration has the advantage that unintentional slipping of the holder relative to the first and / or second mold can be prevented. This allows, in particular, a precise positioning of the first holding space relative to the mold space to be reliably determined.

[0019] In a further embodiment, the mold system comprises a holder fastening, wherein the mold has a holder receptacle. The holder receptacle opens into the mold cavity. The holder is arranged in sections within the holder receptacle. The holder fastening covers at least sections of the holder receptacle and secures the holder in the holder receptacle. The holder fastening is also connected to the mold. This reliably prevents the holder from accidentally slipping out, particularly during demolding.

[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 section of a wiring harness 10 according to a first embodiment for a motor vehicle.

[0024] The cable harness 10 has a cable bundle 15 with a plurality of electrical cables 20, 25. The cable harness 10 also has a sheath 30. The sheath 30 surrounds the cable bundle 15 on its circumference and fixes the electrical cables 20, 25 to one another. The sheath 30 preferably comprises a foam material. It is particularly advantageous if the sheath 30 comprises at least one of the following first materials: polyurethane, open-cell foam, closed-cell foam, mixed-cell foam, polymer, polymer filler matrix, silicone. The sheath 30 mechanically protects the cable bundle 15 from damage. Furthermore, the sheath 30 firmly connects the electrical cables 20, 25 of the cable bundle 15 to one another.

[0025] The sheath 30 has at least a first sheath section 35, a constriction 40, and a second sheath section 45. The second sheath section 45 is arranged at a distance from the first sheath section 35 in the longitudinal direction of the cable bundle 15 (x-direction). The constriction 40 is arranged between the first sheath section 35 and the second sheath section 45. Preferably, the sheath 30 has a plurality of first and second sheath sections 35, 40 spaced apart in the longitudinal direction, each of which is separated from one another by the constriction 40.

[0026] In the first and / or second sheathing sections 35, 40, a layer 55 of the first material is arranged between an outer circumferential side 50 of the sheathing 30 and the cable bundle 15. The layer 55 thus covers the cable bundle 15 circumferentially, so that the cable bundle 15 is guided at a distance from the outer circumferential side 50 of the sheathing 30. At the constriction 40, the layer 55 is interrupted, so that at the constriction 40, the cable bundle 15 is not circumferentially covered by the layer 55 and the sheathing 30.

[0027] In the longitudinal direction, the constriction 40 is significantly narrower than the first and / or second sheathing section 35, 40, so that despite the constriction 40, the cable bundle 15 is protected by the sheathing 30, in particular the layer 55.

[0028] Fig. 2 shows a molding system 70 according to a first embodiment for producing the Fig. 1 shown exemplary wiring harness 10.

[0029] In Fig. For reasons of clarity, only the cable bundle 15 of the cable harness 10 is shown in Fig. 2, whereby the sheath 30 is not shown.

[0030] The molding system 70 has at least one holder 75 and a first mold 80. Additionally, the molding system 70 can have a second mold 85. The holder 75 is arranged, for example, between the first mold 80 and the second mold 85. If the second mold 85 is omitted, the holder 75 can also be arranged at a longitudinal end of the first mold 80. The holder 75 is mechanically connected to the first mold 80 and preferably also to the second mold 85. This ensures the positioning of the holder 75 relative to the first mold 80 and / or the second mold 85.

[0031] The first mold 80 and the second mold 85 are in turn preferably mechanically connected to a mounting board 86. Fig. 2, the mounting board 86 is arranged underneath the first mold 80 and / or the second mold 85. The mold 80, 85 comprises at least one of the following second materials: polypropylene, polyethylene, polytetrafluoroethylene, silicone. The holder 75 comprises a third material, wherein the third material is significantly more elastic than the second material. It is particularly advantageous if the holder 75 comprises at least one of the following third materials: PE-LD, rubber, silicone, elastomer.

[0032] The mold 80, 85 is each designed as an open mold. An open mold means that the mold 80, 85 has a mold insertion opening 90, wherein the mold insertion opening 90 is preferably uncovered during foaming of the foam material. The mold insertion opening 90 is open at the top. The mold 80, 85 each has a first wall 95, a second wall 100 arranged transversely opposite the first wall 95, and a bottom section 105, wherein the first wall 95 and the second wall 100 extend in the same direction away from the bottom section 105. The bottom section 105 delimits a molding space 110 of the mold 80, 85 on the underside. In the transverse direction, the molding space 110 is delimited by the first wall 95 and the second wall 100. The mold insertion opening 90 is arranged opposite the base section 105 in the z-direction. A cross-section of the mold cavity 110 can be rectangular.

[0033] Fig. 3 shows a sectional view along a Fig. 2 shown section plane AA through the mold system 70.

[0034] The holder 75 has a closure section 115 and a receiving section 120. The receiving section 120 adjoins the closure section 115 along an insertion axis 125, which runs, for example, parallel to the z-axis. The receiving section 120 circumferentially delimits at least one first holding space 130 in the y- and z-directions. The receiving section 120 can be U-shaped. The first holding space 130 can be arranged approximately centrally in the transverse direction and at a distance from the first wall 95 and / or second wall 100. In the z-direction, the first holding space 130 is arranged at a distance from the base section 105.

[0035] In the longitudinal direction, the first holding space 130 is open on both end faces of the holder 75. The first holding space 130 thus opens longitudinally into both the mold space 110 of the first mold 80 and the mold space 110 of the second mold 85. In other words, the first holding space 130 connects, for example, the mold space 80 of the first mold 80 with the mold space of the second mold 85.

[0036] The holder 75 has in Fig. 3 has a first side surface 135 on the top side. The first side surface 135 preferably extends in an xy plane. The first side surface 135 can be flush with the first and / or second wall 95, 100. Opposite in the z direction, the holder 75 has a second side surface 140, wherein the first and second side surfaces 135, 140 are preferably guided parallel to one another, for example. The first holding space 130 is arranged at a distance from the second side surface 140 and is closed off from the second side surface 140. The first holding space 130 tapers towards the first side surface 135.

[0037] The closure section 115 has a first insertion opening 145, wherein the first insertion opening 145 is arranged in the first side surface 135. The first insertion opening 145 opens in the z-direction opposite the first side surface 135 in the first holding space 130. The first insertion opening 145 can be nozzle-shaped, as in Fig. 3. The first insertion opening 145 is divided into a first section 146 and a second section 147. The first insertion opening 145 tapers in the first section 146 from the first side surface 135 toward the second side surface 140 and the first holding space 130 and then widens again in the second section 146. The first insertion opening 145 opens into the first holding space 130. The first insertion opening 145 extends along the insertion axis 125.

[0038] In Fig. 3, the holder 75 is shown in a first molded state. In the first molded state, the closure portion 115 elastically and reversibly closes the first insertion opening 145. It is particularly advantageous if the closure portion 115 is relaxed in the first molded state. In the first molded state, the insertion opening 145 can be slit-shaped at a constriction 176 of the first insertion opening 145. The constriction 176 is arranged between the first partial section 146 and the second partial section 147. Alternatively, the closure portion 115 can be in contact at the constriction 176, so that the first insertion opening 145 is completely closed in the z-direction at the constriction 176.

[0039] The closure section 115 has a first closure body 150, a second closure body 155, a first closure element 160, and preferably a second closure element 165. In this embodiment, the first closure body 150 and the second closure body 155 are essentially bar-shaped in sectional view and adjoin the wall 95, 100 in the longitudinal direction. In particular, for example, with respect to the x-axis, the first closure body 150 is arranged in alignment with the first wall 95 and the second closure body 155 is arranged in alignment with the second wall 100. On the underside (in the z-direction), the closure body 150, 155 each adjoins the receiving section 120. The receiving section 120 connects, for example, the first closure body 150 to the second closure body 155 in the transverse direction.

[0040] On the transverse side facing the second closure body 155, the first closure element 160 adjoins the first closure body 150. The first closure element 160 tapers from a first fixed end 170, at which the first closure element 160 is connected to the first closure body 150, towards the second closure body 155. In Fig. 3, for example, the first closure element 160 has a substantially triangular cross-section. On the side facing the second closure element 165, the first closure element 160 delimits the first insertion opening 145 and defines a maximum opening width of the first insertion opening 145. The first free end 175 delimits the constriction 176.

[0041] In Fig. 3, as already explained above, the closure section 115 optionally has the second closure element 165 in addition to the first closure element 160. The second closure element 165 can also be omitted. In the embodiment, for example, the first closure element 160 and the second closure element 165 are mirror-symmetrical to a plane of symmetry 177. The plane of symmetry 177 can be formed as an xz plane and arranged in a central position with respect to a maximum transverse extent of the holder 75. Of course, an asymmetrical structure of the holder 75, in particular of the closure section 115, is also possible.

[0042] The second closure element 165 is arranged transversely between the first closure element 160 and the second closure body 155. The second closure element 165 is connected, for example, by a second fixed end 180 to the second closure body 155. From the second fixed end 180, the second closure element 165 extends transversely toward the first closure element 160. On the transverse side facing the first closure element 160, the second closure element 165 delimits the first insertion opening 145. At a second free end 185, the second closure element 165, together with the first free end 175, delimits the constriction 176. In particular, the second free end 185, together with the first free end 175, delimits a maximum opening cross-section of the first insertion opening 145 at the narrowest point of the first insertion opening 145.

[0043] In Fig. 3, the second closure element 165, as well as the first closure element 160, is shown in the first molded state, wherein preferably the second closure element 165, as well as the first closure element 160, is relaxed. In Fig. 3, for example, the second closure element 165 has a triangular design.

[0044] In the first molding state, as described above, the first closure element 160 and / or the second closure element 165 are, for example, relaxed and close the first insertion opening 145. The first closure element 160 and the second closure element 165 can be in contact with each other, in particular in the region of the free end 175, 185 and thus at the constriction 176.

[0045] In an alternative embodiment, the first free end 175 and the second free end 185 of the respectively associated closure element 160, 165 are arranged at a distance from one another, so that the first closure element 160 and / or the second closure element 165 do not touch each other. It is also particularly advantageous if the first closure element 160 and the second closure element 165, in particular the first and second free ends 175, 185 of the respective closure element 160, 165, are arranged in a common plane, in particular in a common xy plane.

[0046] Fig. 4 shows a sectional view along the Fig. 2 through the holder 75 of the molding system 70 in a second molding state.

[0047] In the second molding state, the first closure element 160 is in relation to the first molding state (cf. Fig. 3) elastically reversibly deformed. In particular, Fig. 4, the first closure element 160 is compressed in the transverse direction towards the first closure body 150 and away from the first insertion opening 145. Due to the compression of the first closure element 160, the first insertion opening 145 is in the second mold state of the first closure element 160 compared to the Fig. 3. Due to the compression of the first closure element 160, the first closure element 160 is tensioned in the second shape.

[0048] Analogous to the first closure element 160, the second closure element 165 can be converted into the second mold state in the same way as the first closure element 160. In Fig. 4, this is achieved by elastically reversibly deforming the second closure element 165 in the transverse direction away from the first insertion opening 145 in the direction of the second closure body 155. The deformation can be designed, in particular, such that the second closure element 165, in the second molded state, is compressed in the transverse direction away from the first insertion opening 145. As a result, the first insertion opening 145 can be widened particularly widely. In the second molded state, the first insertion opening 145 has at least a maximum opening width at the constriction 176, which corresponds at least to a maximum diameter of the electrical cable 20, 25. In the first molded state, the maximum opening width is smaller than the maximum diameter of the electrical cable 20, 25.

[0049] Due to the widely widened first insertion opening 145, the first holding space 130 is easily accessible from the first side surface 135 in the second molding state.

[0050] Furthermore, the reversibly elastic deformation of the closure element 160, 165 is understood to mean that the first and / or second closure element 160, 165 can be deformed, for example, compressed, at least 10,000 to 1,000,000 times between the first deformed state and the second deformed state, without, for example, cracks or other mechanical wear phenomena forming on the holder 75. Furthermore, the deformation of the first and / or second closure element 160, 165 occurs without plastic deformation.

[0051] Fig. 5 shows a flow diagram of a method for producing the Fig. 1 wiring harness 10.

[0052] In a first method step 205, the Fig. 2 and Fig. 3 is provided with at least one holder 75. Preferably, the molding system 70 has a plurality of holders 75 arranged at a distance from one another in the longitudinal direction. In the first method step, the holders 75 are each in the first molding state.

[0053] In a second method step 210 following the first method step 205, the first electrical cable 20 is inserted and routed into the mold cavity 110 along a predefined cable path. For example, the first electrical cable 20 is inserted from above into the mold cavity 110 of the first mold 80 via the mold insertion opening 90.

[0054] In order to insert the first cable 20 into the mold cavity 110 of the second mold 85, the first electrical cable 20 is introduced into the first holding chamber 130. This is done by elastically reversibly deforming the closure section 115 in a third method step 215 following the second method step 210. For this purpose, as shown in Fig. 4, for example, by means of an insertion means 181, for example a gripper of a robot arm or by means of a finger of a human hand, the first closure element 160 and preferably the second closure element 165 are compressed and transferred from the first mold state to the second mold state. For this purpose, the insertion means 181 presses the first electrical cable 20 to be inserted from above into the first insertion opening 145. In this case, the insertion means 181 can engage in the mold space 110 of the first mold 80 and / or the second mold 85. Alternatively, the insertion means 181 can also be inserted from above together with the first electrical cable 20 into the first insertion opening 145.

[0055] The first electrical cable 20, 25 slides circumferentially along the closure surfaces of the closure element 160, 165 arranged obliquely to the insertion axis 125, widening the first insertion opening 145 and transferring the closure element 160, 165 from the first molded state to the second molded state. After passing the constriction 176, the inclined closure surface can assist the insertion movement of the first electrical cable 20 along the insertion axis 125 by the self-relaxing closure element 160, 165 in conjunction with the surface of the closure element 160, 165 arranged obliquely to the insertion axis 125 in the direction of the first holding space 130.

[0056] If, after the third method step 215, the first electrical cable 20 is located in the first holding space 130, the insert means 181 is removed from the mold space 110 of the first and / or second mold 80, 85 and / or from the first insertion opening 145 in a fourth method step 220 following the third method step 215.

[0057] Because in the third method step 215 the first closure element 160 and preferably the second closure element 165 were compressed and / or tensioned and relaxed again during transfer from the first molded state to the second molded state, the closure element 160, 165 is in the relaxed first molded state in the fourth method step 220, so that the first insertion opening 145 is automatically closed by the closure section 115 in the fourth method step 220, without the need for any further aids.

[0058] Through the closed first insertion opening 145, the first closure element 160 and preferably also the second closure element 165 holds the first electrical cable 20 inserted into the first holding space 130 and prevents it from slipping out in the z-direction along the insertion axis 125 from the first holding space 130, even when the insertion means 181 is removed from the mold space 110 and / or the first insertion opening 145.

[0059] In a fifth method step 225 following the fourth method step 220, the first electrical cable 20 is further introduced into the mold space 110 of the second mold 85, for example by means of the insertion means 181.

[0060] The third to fifth method steps 215, 220, 225 are repeated for the first electrical cable 20 on the additional holders 75 of the molding system 70 until the first electrical cable 20 is inserted into the molding space 110 of the molds 80, 85 of the molding system 70 along the planned cable path. The holder 75 prevents the first electrical cable 20 from accidentally slipping out and fixes the first electrical cable 20 along the cable path.

[0061] The second to fifth method steps 210, 215, 220, 225 are also repeated for further first and second electrical cables 20, 25 until all electrical cables 20, 25 of the cable bundle 15 are inserted into the molding space 110.

[0062] In a sixth method step 230 following the fifth method step 225, which is carried out when all electrical cables 20, 25 of the cable bundle 15 have been introduced into the molding space 110 of the molds 80, 85, a first precursor and / or a mixture of a first precursor and a second precursor and / or the first material in the liquid phase state is introduced into the molding space 110.

[0063] Preferably, the first precursor and / or the mixture of the first and second precursor and / or the first liquid material has a low viscosity. The first precursor and / or the mixture of the first and second precursor and / or the low-viscosity first material flow from the penetration position toward the base section 105. In this case, the first precursor and / or the mixture of the first and second precursor and / or the first liquid material encloses the cable bundle 15. In this case, the first precursor and / or the mixture of the first and second precursor and / or the low-viscosity first material can flow from the molding space 110 into the first holding space 130 and also enclose the cable bundle 15 there.

[0064] In the sixth process step 230, which is optional, the first precursor and / or the mixture of the first precursor and the second precursor and / or the liquid first material is foamed. Foaming can be performed mechanically and / or chemically. For example, the first and second precursors can be selected such that the first and second precursors chemically react with each other and foam in the process.

[0065] The sixth method step 230 can also be carried out such that, upon introduction of the first material and / or the mixture of the first and second precursor products and / or the first precursor product, the first precursor product and / or the mixture of the first and second precursor products and / or the first material is / are foamed, in particular, if appropriate, mechanically and / or chemically foamed. In particular, it is conceivable that, upon foaming of the first material and / or the mixture of the first and second precursor products, said material oozes out upwards through the insertion opening 90. Likewise, the first precursor product and / or the mixture of the first and second precursor products and / or the first material foams up in the first holding space 130.

[0066] In a seventh method step 235 following the sixth method step 230, the first precursor and / or the mixture of the first and second precursors and / or the first material is cured to form the foam material of the casing 30. Curing is understood to mean that the liquid first precursor and / or the liquid mixture of the first and second precursors and / or the liquid first material present up to the sixth method step 230 undergoes crosslinking in a solid phase state to form the foam material of the casing 30. In this process, the first and second casing sections 35, 45 and the constriction are formed.

[0067] In an eighth method step 240 following the seventh method step 235, which is preferably carried out when the sheath 30 has at least partially, preferably substantially completely, cured, the cable harness 10 is removed from the mold space 110.

[0068] The removal takes place in that the cable harness 10 is pulled out of the respective molding chamber 110 of the mold 80, 85 at the first and second sheathing sections 35, 40 in the z-direction. In the area of the holder 75, in particular the constriction 40 formed in the cable harness 10 by the holder 75 and the first holding chamber 130, the cable harness 10 is also pulled upwards. The constriction 40 and the cable bundle 15 running along the constriction 40 deform the closure section 115. In particular, the cable bundle 15 compresses the first and / or second closure element 160, 165 and deforms it from the first molding state into the second molding state, so that, as in Fig. 4, the closure section 115, in particular the first and / or second closure element 160, 165, is deformed, in particular compressed. As a result, the first insertion opening 145 is widened, and the cable bundle 15 can be pulled out of the first holding space 130 via the first insertion opening 145. The holder 75 remains attached to the mold 80, 85. The holder 75 is again elastically and reversibly deformed upon removal.

[0069] After the cable bundle 15 and the cable harness 10 have been removed from the molding system 70 in the eighth method step 240, in a ninth method step 245 following the eighth method step 240, the closure element 160, 165 automatically returns from the second molding state to the first molding state due to the tensioned state of the first and second closure elements 160, 165, so that the second method step 210 can be continued and new electrical cables 20, 25 for a new cable harness 10 can be inserted into the molding system 70.

[0070] In summary, the holder 75 facilitates the assembly and tightening of the individual electrical cables 20, 25 when routing the electrical cables 20, 25 in the forming system 70. Furthermore, the insertion can be automated since it is a simple rectilinear movement along the insertion axis 125.

[0071] Fig. 6 shows a cross section through the Fig. 1 shown wiring harness 10 in the area of the constriction 40.

[0072] The constriction 40 essentially has the shape of the first holding space 130 plus, for example, the second partial section 147 of the first insertion opening 145, between the constriction 176 and the holding space 130, wherein the electrical cables 20, 25 of the cable bundle 15 are pressed tightly together in the constriction 40. This ensures that the electrical cables 20, 25 of the cable bundle 15 are also guided closely to one another in the first and second sheathing sections 35, 45, and thus the layer 55 on the circumference of the cable bundle 15 protects the cable bundle 15.

[0073] Fig. 7 shows a perspective view of a section of a molding system 70 according to a second embodiment.

[0074] The mold system 70 is essentially identical to that used in the Fig. 2 to 4. In the following, only the differences between the Fig. 7 shown form system 70 compared to that in Fig. The form system 70 shown in Figure 2 is discussed.

[0075] The mold system 70, in particular the first and second molds 80, 85, have an exemplary course.

[0076] Fig. 8 shows a sectional view along a Fig. 7 shown section plane BB through the mold system 70.

[0077] The holder 75 is in Fig. 8 opposite Fig. 3 is varied in that the first holding space 130 is conical. For example, the first holding space 130 and the second section 147 merge seamlessly into one another.

[0078] From the constriction 176, the second partial section 147 and the first holding space 130 widen in the direction of the second side surface 140. This configuration results in the first insertion opening 145 and the first holding space 130 together having a cross-section substantially similar to that of an Erlenmeyer flask.

[0079] By means of the Fig. 7 and Fig. The mold system 70 shown in Figure 8 can be formed by means of the Fig. The wiring harness 10 can be manufactured using the method described in 5.

[0080] Fig. 9 shows a cross section in the region of the constriction 40 through a cable harness 10 according to a second embodiment.

[0081] The wiring harness 10 is essentially identical to that shown in Fig. 1 and Fig. 6 shown wiring harness 10. In the following, only the differences of the wiring harness shown in Fig. 9 shown cable harness 10 according to the second embodiment compared to that shown in the Fig. 1 and Fig. 6 shown wiring harness 10 according to a first embodiment.

[0082] In the area of the constriction 40, the cable harness 10 has a triangular cross-section. Due to the triangular cross-section, the electrical cables 20, 25 of the cable bundle 15 are tightly packed together, and the layer 55 can preferably be wide in the y- and / or z-direction, so that the layer 55 reliably protects the cable bundle 15 from mechanical damage. Furthermore, the layer 55 protects against vibration due to its foam material design, thus preventing the cable harness 10 from striking a component of the vehicle, such as a body component, and rattling of the cable harness 10 can be prevented.

[0083] Fig. 10 shows a schematic representation of a molding system 70 according to a third embodiment.

[0084] The mold system 70 is essentially identical to that used in the Fig. 1 to 9 shown form system 70. In the following, only the differences of the Fig. 10 shown form system 70 compared to the one shown in the Fig. 1 to 5 according to the first embodiment.

[0085] The form 80, 85 has an exemplary different geometric progression compared to the one in the Fig. 2 shown course of the form 80, 85. Furthermore, in Fig. 10, the representation of the second form 85 is essentially omitted. Instead, it is indicated only by dashed lines.

[0086] Fig. 11 shows a sectional view along a Fig. 10 shown section plane CC through the Fig. Form system 70 shown in 10.

[0087] The holder 75 is opposite the one in the Fig. 2 to 5 is modified in that the holder 75 only has the first closure element 160. The second closure element 165 is omitted in this embodiment. The first closure element 160 is, for example, bar-shaped in a bar region 191 that adjoins the first fixed end 170 and tapers in a wedge-shaped manner towards the first free end 175 in an end region 195 that adjoins the bar region 191 in the transverse direction. The first closure element 160 extends essentially in a straight line in the first molded state. For example, in the first molded state, the first free end 175 can rest laterally against the second closure body 155. The second closure body 155, together with the wedge-shaped end region 195 of the first closure element 160, delimits the first insertion opening 145 in the transverse direction.

[0088] In the first molded state of the first closure element 160, the first holding space 130 has a substantially rectangular cross-section. Furthermore, the second partial section 147 of the first insertion opening is omitted.

[0089] In order to insert the electrical cable 20, 25 into the first holding space 130, it is possible to deviate from the Fig. 6, in the fourth method step 220 and in the seventh method step 235, the first closure element 160 is elastically reversibly deformed such that the first closure element 160 can be bent away from the first holding space 130 about a first bending axis 300, which runs, for example, parallel to the x-axis and is thus inclined, in particular oriented perpendicular to the insertion axis 125, or can be bent into the first holding space 130 in order to be transferred into the second shaped state. It is particularly advantageous if, for example, the first closure element 160 is bent, in particular bent into, the first holding space 130 by at least 50°, preferably by at least 70°, or is bent away from the first holding space 130 in the second shaped state.

[0090] Additionally or alternatively, it would also be possible for the first closure element 160 to be bent, in particular pivoted, away from the first holding space 130 by at least 50°, preferably by at least 70°, about a second bending axis 305, which runs parallel to the insertion axis 125, in order to transfer the first closure element 160 into the second shaped state, so that the first closure element 160 is no longer arranged in a common plane with the respective plate-shaped first and second closure bodies 150, 155. Bending the first closure element 160 about the second bending axis 305 has the advantage that the first holding space 130 is particularly easily accessible via the first insertion opening 145.

[0091] In a further development, the movements around the two bending axes 300, 305 can also be carried out simultaneously in combination.

[0092] The fact that the holder 75 is made of the elastically reversibly deformable material ensures that the first closure element 160 can be bent at least 10,000 to 1,000,000 times about the first and / or second bending axis 300, 305 without cracks or other mechanical wear phenomena forming on the holder 75.

[0093] Fig. 12 shows a cross section in the area of the constriction 40 through the Fig. 10 and Fig. 11 shown molding system 70 manufactured cable harness 10 according to a third embodiment.

[0094] In the area of the constriction 40, the cable harness 10 has, for example, a substantially rectangular configuration corresponding to the configuration of the first holding space 130 in the first shape state of the first closure element 160. The cable harness 10 according to Fig. 12 can be used by means of the Fig. 6 described manufacturing process.

[0095] Fig. 13 shows a partial perspective view of a section of a molding system 70 according to a fourth embodiment.

[0096] In Fig. 13, the second form 85 is not shown for reasons of clarity. The form system 70 is essentially identical to the Fig. 1 to 5. In the following, only the differences of the Fig. 13 shown form system 70 compared to the one shown in the Fig. 1 to 5 according to the first embodiment.

[0097] The first insertion opening 145 is zigzag-shaped. The first section 146 and the second section 147 can be slit-shaped with a constant width. The above-described tapered configuration of the first section 146 and the widened configuration of the second section 147 are also possible.

[0098] The constriction 176 is arranged at the joint between the first sub-section 146 and the second sub-section 147. The first sub-section 146 is arranged at an angle to the second sub-section 147. This prevents electrical cables 20, 25 of the cable bundle 15, which have already been inserted into the first holding space 130, from accidentally slipping out. Furthermore, this configuration results in the first closure element 160 forming a closure element receptacle 190, which is arranged at the first free end 175 of the first closure element 160. The closure element receptacle 190 can be approximately wedge-shaped / triangular in sectional view. In the first formed state, the first closure element 160 engages with the second free end 185 in the closure element receptacle 190.

[0099] Fig. 14 shows a perspective view of the holder 75 of the Fig. 13 shown form system 70.

[0100] The first holding space 130 is, for example, triangular in shape and can, for example, have the shape of an isosceles triangle, wherein one leg is guided parallel to the second side surface 140.

[0101] In order to transfer the closure section 115 into the second molded state, it is particularly advantageous if the first closure element 160 is pivoted away from the first holding space 130 about the second bending axis 310 and the second closure element 165 about a third bending axis 315, which runs parallel to the second bending axis 305 and to the insertion axis 125, so that the first and second closure elements 160, 165 protrude at the end beyond the first and second closure bodies 150, 155, respectively, and the first insertion opening 145 is open.

[0102] Fig. 15 shows a cross section through a cable harness 10 according to a fourth embodiment, manufactured by means of the method shown in the Fig. 13 and Fig. 14 shown forming system 70 in the area of the constriction 40.

[0103] The wiring harness 10 is essentially identical to that shown in the Fig. 1 and Fig. 6 shown wiring harness 10. In the following, only the differences of the wiring harness shown in Fig. 15 shown wiring harness 10 compared to the one shown in the Fig. 1 and Fig. 6 shown wiring harness 10.

[0104] In the area of the constriction 40, the cable harness 10 has a substantially triangular configuration. In particular, the cable harness 10 can have the shape of an isosceles triangle at the constriction 40, with one side of the triangle running parallel to an underside of the cable harness 10.

[0105] Fig. 16A shows a perspective view of a holder 75 of a molding system 70 according to a fifth embodiment. Fig. 16B shows the Fig. 16A with the cable bundle 15 of a cable harness 10 according to a fifth embodiment.

[0106] The mold system 70 according to the fifth embodiment is substantially identical to that shown in the Fig. 2 to 5. In the following, only the differences between the Fig. 16A and Fig. 16B described mold system 70 of the fifth embodiment compared to the one shown in the Fig. 2 to 5 described molding system 70 according to the first embodiment and the cable harness 10 according to the first embodiment. Furthermore, it is pointed out that by means of the Fig. 16A and Fig. 16B shown mold system 70 each also the cable harness 10 with the in Fig. 6. If necessary, it can also be used as described in the Fig. 10 and Fig. 11, the first holding space 130 can be opened through the first insertion opening 145.

[0107] In the Fig. 16A and Fig. 16B, the first holding space 130 is polygonal, so that the first and second closure elements 160, 165 are particularly short in the z-direction and are not only compressed, as in Fig. 6, but also analogously, as in the Fig. 10 and Fig. 11, can be bent and pivoted about the second and third bending axes 305, 315 in order to widen the first insertion opening 145.

[0108] In this case, Fig. 16A the holder 75 is shown without inserted cable bundle 15, while in Fig. 16B shows the cable harness 10 in the region of the constriction 40 prior to the sixth method step 230. Due to the polygonal configuration of the first holding space 130 in conjunction with the second partial section 147 of the first insertion opening 145, the cable harness 10 has a heptagonal cross-section in the region of the constriction 40.

[0109] Fig. 17A shows a perspective view of a holder 75 of a molding system 70 according to a sixth embodiment. Fig. 17B shows the Fig. 17A with the cable bundle 15 of a cable harness 10 according to a sixth embodiment.

[0110] The mold system 70 according to the sixth embodiment is substantially identical to that shown in the Fig. 2 to 5. In the following, only the differences between the Fig. 17A and Fig. 17B described mold system 70 of the sixth embodiment compared to the one shown in the Fig. 2 to 5 described molding system 70 according to the first embodiment and the cable harness 10 according to the first embodiment. Furthermore, it is pointed out that by means of the Fig. 17A and Fig. 17B shown mold system 70 also the cable harness 10 with the in Fig. 6. If necessary, it can also be used as described in the Fig. 10 and Fig. 11, the first holding space 130 can be opened through the first insertion opening 145.

[0111] In the Fig. 17A and Fig. 17B, the first holding space 130 is the same as in the Fig. 16A and Fig. 16B is polygonal, but in the Fig. 17A and Fig. 17B the first holding space 130 wider than in the Fig. 16A and Fig. 16B. Furthermore, the first holding space 130, together with the second partial section 147 of the first insertion opening 145, is essentially pentagonal. Due to the polygonal configuration of the first holding space 130 in conjunction with the second partial section 147 of the first insertion opening 145, the cable harness 10 has a pentagonal cross-section in the region of the constriction 40.

[0112] Fig. 18A shows a perspective view of a holder 75 of a molding system 70 according to a seventh embodiment. Fig. 18B shows the Fig. 18A with the cable bundle 15 of a cable harness 10 according to a seventh embodiment.

[0113] The mold system 70 according to the seventh embodiment is substantially identical to that shown in the Fig. 16A and Fig. 16B. In the following, only the differences between the Fig. 18A and Fig. 18B described mold system 70 of the seventh embodiment compared to the one shown in the Fig. 16A and Fig. 16B, the molding system 70 according to the fifth embodiment and the cable harness 10 according to the fifth embodiment will be discussed. Furthermore, it is pointed out that by means of the Fig. 18A and Fig. 18B shown mold system 70 each also the cable harness 10 with the in Fig. 6. If necessary, it can also be used as described in the Fig. 10 and Fig. 11, the first holding space 130 is opened through the first insertion opening 145. In Fig. 18, the first holding space 130 is particularly wide in both the transverse direction and the z-direction, in particular significantly wider than in the Fig. 16A and Fig. 16B. The second section 147 of the first insertion opening 145 widens significantly further in the transverse direction than the first section 146. The first section 146 can be slit-shaped.

[0114] Fig. 19A shows a perspective view of a holder 75 of a molding system 70 according to an eighth embodiment. Fig. 19B shows the Fig. 19A with the cable bundle 15 of a cable harness 10 according to an eighth embodiment.

[0115] The Fig. 19A and the mold system 70 shown in Fig. 19B shown wiring harness 10 according to the eighth embodiment are essentially a development of the one shown in Fig. 16A, Fig. 16B and Fig. 17A, Fig. 17B and the cable harness 10, wherein the first holding space 130 together with the second section 147 is oval.

[0116] Fig. 20 and Fig. 21 show a perspective view of a molding system 70 according to a ninth embodiment. The molding system 70 is substantially identical to the molding system shown in Fig. 2 to 5 described mold system 70.

[0117] The closure section 115 of the Fig. 20 and Fig. The holder 75 shown in Figure 21 has, in addition to the first holding space 130, a second insertion opening 320 and a second holding space 325. The second insertion opening 320 is arranged on the first side surface 135 and is offset in the transverse direction from the first insertion opening 145. The second holding space 325 adjoins the second insertion opening 320 on the underside in the z-direction.

[0118] In the exemplary embodiment, the second insertion opening 320 and the second holding space 325 are configured identically to the first insertion opening 145 and the first holding space 130. Of course, a different configuration of the holding spaces 130, 325 and the two insertion openings 145, 320 would also be conceivable.

[0119] The Fig. The method described in Figure 5 can also be applied to the second holding space 325. In this case, the closure portion 115 is additionally elastically reversibly deformable between the first molding state and a fifth molding state. In the first molding state, the closure portion 115 closes the second insertion opening 320. In the fifth molding state, which differs from the first to fourth molding states, the second insertion opening 320 is widened compared to the first molding state. In this case, the cables 20, 25 can be inserted into the second holding space 325 through the second insertion opening 320 in the fifth molding state.

[0120] Due to the offset in the transverse direction, the cable bundle 15 can be guided in two parts within the sheath 30, thus ensuring particularly good embedding of the electrical cables 20, 25 in the foam material of the sheath 30. This also prevents the cable bundle 15 from being too wide in the transverse direction, thus ensuring good flow of the first precursor and / or the mixture of the first precursor and the second precursor and / or the first liquid material in the region of the constriction 40.

[0121] Fig. 22 shows a perspective view of a molding system 70 according to a tenth embodiment.

[0122] The mold system 70 is essentially identical to that used in the Fig. 1 to 6. In the following, only the differences of the Fig. 22 shown mold system 70 and cable harness 10 compared to the one shown in the Fig. 1 to 5 shown mold system 70 and wiring harness 10.

[0123] The holder 75 has a further closure section 326 and a further receiving section 327. The further closure section 326 adjoins the receiving section 120 in the z-direction on a side facing the second side surface 140 and thus on a side facing away from the closure section 115. The further receiving section 327 adjoins the further closure section 326 in the z-direction on a side facing the second side surface 140 and thus on a side facing away from the closure section 115.

[0124] In the embodiment, the closure section 115 and the further closure section 326 are, for example, identical to one another. The further closure section 326 and the closure section 115 can also be designed differently from one another. In particular, the various configurations of the Fig. 1 to 21 described embodiments of the closure section 115 for the closure section 115 and the further closure section 326 are applied and combined with each other.

[0125] The further receiving portion 327 has a third holding space 330 between the second side surface 140 and the first holding space 130. The third holding space 330 is connected to the first holding space 130 via a constriction 335 of the further closure portion 326.

[0126] The receiving section 120 and the further receiving section 327 can be identical or different from each other. In particular, the Fig. 1 to 21 for the first holding space 130 and the receiving section 120 can be applied to the further receiving section 327 and the third holding space 330. In particular, the different geometric configurations of the receiving sections 120 and the first holding space 130 can be combined with each other. For example, the first holding space 130 is as shown in Fig. 16A and Fig. 16B and the third holding space 330 is as shown in the Fig. 7 to 9 for the first holding space 130 is triangular in shape.

[0127] Fig. 23 shows a perspective view of the holder 75 of the Fig. 22 shown form system 70.

[0128] For example, the third holding space 330 has a triangular configuration, while the first holding space 130, for example, is designed to extend elongatedly along the insertion axis 125 in a straight line. In particular, the first holding space 130 can be polygonal, for example, pentagonal or heptagonal.

[0129] An electrical cable 20, 25 can be displaced between the first holding space 130 and the third holding space 330 along the z-direction via the constriction 335, which, for example, has the same minimum width in the transverse direction as the first insertion opening 145 at the constriction 176.

[0130] Thanks to the first and third holding spaces 130, 330, the cable bundle 15 can be particularly slim in the transverse direction, even when a large number of electrical cables 20, 25 are accommodated. The transition between the first holding space 130 and the third holding space 330 is secured by the same locking mechanism as the first insertion opening 145, so that the holder 75 prevents an already inserted electrical cable 20, 25 from accidentally passing into the other holding space 130, 330.

[0131] The further closure section 326 can additionally have a third closure element 340 and a fourth closure element 345, wherein the third closure element 340 is functionally and / or geometrically identical to the first closure element 160 and the fourth closure element 345 is functionally and / or geometrically identical to the second closure element 165. The third and fourth closure elements 340, 345 can be actuated independently of the first and second closure elements 160, 165, so that, independently of the first insertion opening 145, the constriction 335 is widened when the third and / or fourth closure element 340, 345 is transferred from a relaxed, normally present third shaped state to a tensioned fourth shaped state. In the fourth shaped state, the third and / or fourth closure element 340, 345 can be elastically reversibly deformed, for example, compressed in the transverse direction.Additionally or alternatively, it is also conceivable for the third and / or fourth closure element 340, 345 to be bent by at least 50°, preferably at least 70°, around a fourth bending axis 350 into the third holding space 330 or away from the third holding space 330 into the first holding space 130. The fourth bending axis 350 runs parallel to the longitudinal axis or inclined, in particular perpendicular to the insertion axis 125. The fourth bending axis 350 can also run parallel to the insertion axis 125 and to the z-axis.

[0132] Fig. 24 shows a perspective view of a molding system 70 according to an eleventh embodiment.

[0133] The mold system 70 is essentially identical to that used in the Fig. 2 to 23. In the following, only the differences of the Fig. 24 compared to the mold system 70 shown in the Fig. The form system 70 shown in Figures 2 to 5 is discussed.

[0134] By way of example, the first mold 80 has a first holder receptacle 400 and a second holder receptacle 405 arranged transversely opposite the first holder receptacle 400. The first holder receptacle 400 is arranged, for example, in the first wall 95 and the second holder receptacle 405 is arranged in the second wall 100. Both the first holder receptacle 400 and the second holder receptacle 405 are, for example, open towards the mold cavity 110 and on the side facing away from the base section 105. Thus, the holder receptacles 400, 405 can each be groove-shaped in the associated wall 95, 100. The holder 75 engages with a first holder section 410 in the first holder receptacle 400 and with a second holder section 415 in the second holder receptacle 405.The first holder portion 410 may extend at least partially or completely over the first closure body 150 and the second holder portion 415 may extend partially or completely over the second closure body 155.

[0135] In addition, the mold system 70 has a holder attachment 420. The holder attachment 420 is arranged, for example, on the top side of the first mold 80 and serves to attach the holder 75 to the first mold 80 at least in the z-direction.

[0136] Fig. 25 shows a section of a perspective top view of the Fig. 24 shown form system 70.

[0137] In the embodiment, the holder attachment 420 has a first holder attachment part 425 and preferably a second holder attachment part 430. The first holder attachment part 425 is attached, for example, screwed, to the top of the first wall 95. The second holder attachment part 430 is attached, preferably screwed, to the top of the second wall 100. The first holder attachment part 425 at least partially closes the top of the first holder receptacle 400. Likewise, the second holder attachment part 430 closes the top of the second holder receptacle 405.

[0138] The holder fastening part 425, 430 can, for example, be plate-shaped. In this embodiment, the first holder fastening part 425 and the second holder fastening part 430 can, for example, be mirror-symmetrical to the plane of symmetry 435 arranged between the first holder fastening part 425 and the second holder fastening part 430.

[0139] Fig. 26A shows a side view of the holder 75 of the Fig. 25 shown form system 70. Fig. 26B shows a plan view of the Fig. 26A shown holder 75. In the following, the Fig. 26A and Fig. 26B described together.

[0140] The holder 75 is essentially identical to the one in Fig. 8 described holder 75. In the following, only the differences of the Fig. 26A, Fig. 26B shown holder.

[0141] On the upper side facing the first insertion opening 145, the holder 75 has a first shoulder 440 and a second shoulder 445 arranged transversely opposite the first shoulder 440. Between the first shoulder 440 and the second shoulder 445, the holder 75 is raised at the first insertion opening 145. The first shoulder 440 and the second shoulder 445 extend laterally outward in the transverse direction.

[0142] In the transverse direction between the first shoulder 440 and the second shoulder 445, the holder 75 has an intermediate section 446, wherein the intermediate section 446 projects beyond the first shoulder 440 and the second shoulder 445 in the z-direction. The intermediate section 446 can have the first insertion opening 145. The first shoulder 440 and the second shoulder 445 can be arranged extending in a common xy plane.

[0143] Fig. 27 shows a plan view of the holder fastening part 425, 430 of the Fig. 25 shown form system 70.

[0144] The holder fastening part 425, 430 has a plate-shaped configuration extending elongately in the longitudinal direction, for example. On a longitudinal side 450, the holder fastening part 425, 430 has a third insertion opening 455, which is groove-shaped and runs in the z-direction. The third insertion opening 455 can be arranged centrally relative to a maximum longitudinal extent of the holder fastening part 425, 430. The third insertion opening 455 is open toward the longitudinal side 450 and is designed as a through-opening in the z-direction. The third insertion opening 455 can have a rectangular cross-section. In particular, the third insertion opening 455 can be designed to correspond to the intermediate section 446.

[0145] Additionally, the holder fastening part 425, 430 can have at least one, preferably two, bores 459, each of which is arranged in the region of a respective longitudinal end of the holder fastening part 425, 430. In the longitudinal direction, for example, the third insertion opening 455 is arranged between the two bores 459.

[0146] Fig. 28 shows a sectional view along a Fig. 27 shown section plane DD through the Fig. Holder 75 shown in 27.

[0147] The third insertion opening 455 can be configured such that, starting from a contact surface 460 of the holder fastening part 425, 430, against which the holder fastening part 425, 430 rests against the wall 95, 100, it widens toward an upper side 461 facing away from the contact surface 460. This ensures that, in the assembled state of the holder fastening part 425, 430, the third insertion opening 455 is preferably pressed well into the intermediate section 446.

[0148] In the assembled state, the contact surface 460 closes the associated first holder receptacle 400 or the associated second holder receptacle 405 on the top side and fixes the holder 75 in the respectively associated holder receptacle 400, 405. In particular, the contact surface 460 can allow the first holder fastening part 425 to rest on the first shoulder 440 and the second holder fastening part 430 to rest on the second shoulder 445 and prevent the holder 75 from being accidentally pulled out of the first mold 80, in particular from the first holder receptacle 400 and the second holder receptacle 405 in the z-direction, for example when dismantling the finished wiring harness 10.

[0149] Fig. 29 shows a perspective view of a molding system 70 according to a twelfth embodiment.

[0150] The mold system 70 is essentially identical to that used in the Fig. 2 to 28. In the following, only the differences of the Fig. 29 shown form system 70 compared to the one shown in the Fig. The form system 70 shown in Figures 2 to 5 is discussed.

[0151] In Fig. 29, the holder 75 is wider in the transverse direction than in the Fig. 2 to 5. In particular, the holder 75 projects laterally beyond the first mold 80. Furthermore, the holder 75 is not arranged between the first and second molds 80, 85, but directly on the first mold 80.

[0152] The holder 75 has a first wall receptacle 465 and preferably a second wall receptacle 470, wherein the first wall receptacle 465 and the second wall receptacle 470 are arranged offset from one another in the transverse direction. The first insertion opening 145 is arranged in the transverse direction between the first wall receptacle 465 and the second wall receptacle 470.

[0153] The first wall receptacle 465 is preferably configured to correspond to the first wall 95, and the second wall receptacle 470 is configured to correspond to the second wall 100. The first wall receptacle 465 and the second wall receptacle 470 are configured to be open toward the base section 105. Furthermore, the wall receptacles 465, 470 are configured as a through-opening in the longitudinal direction.

[0154] The holder 75 is placed in the z-direction from the mold insertion opening 90 to the base section 105 on the first mold 80, so that the first wall 95 passes through the first wall receptacle 465 and the second wall 100 passes through the second wall receptacle 470 in the longitudinal direction.

[0155] The wall receptacle 465, 470 can, for example, be groove-shaped. It is particularly advantageous if the wall receptacle 465, 470 is slightly smaller than the associated wall 95, 100, so that when the holder 75 is placed onto the first mold 80, the holder 75 is expanded and thereby tensioned in the region of the respective wall receptacle 465, 470. Due to the tensioning of the holder 75 in the region of the wall receptacle 465, 470, the holder 75 presses against the respective wall 95, 100 and forms a frictional connection with the wall 95, 100.

[0156] It is particularly advantageous if the holder 75 rests against the bottom section 105 on its underside. This allows the attachment of the holder 75 to the first mold 80 to be limited in the z-direction.

[0157] Fig. 30 shows a perspective view of a molding system 70 according to a thirteenth embodiment.

[0158] The mold system 70 is essentially identical to that used in the Fig. 2 to 29. In the following, only the differences of the Fig. 30 shown form system 70 compared to the one shown in the Fig. The form system 70 shown in Figures 2 to 5 is discussed.

[0159] The holder 75 is in contrast to the one in the Fig. 2 to 5, the holder 75 is arranged exclusively on the first mold 80 and not between the first mold 80 and the second mold 85. The holder 75 is, for example, shorter in the transverse direction than the first mold 80. Laterally, the holder 75 has a first tab 475 and preferably a second tab 480 arranged transversely opposite the first tab 475. The first tab 475 and / or the second tab 480 are each plate-shaped. The holder 75 projects beyond the mold insertion opening 90 in the z-direction and thus projects out of the mold insertion opening 90 and the mold cavity 110.

[0160] The first tab 475 is arranged on the top side of the first wall 95, and the second tab 480 is arranged on the top side of the second wall 100. The tabs 475, 480 ensure that, when the cable harness 10 is to be removed from the mold cavity 110 and the holder 75 after the cable harness 10 has been manufactured, the holder 75 can be pressed from above onto the first mold 80, in particular onto the first wall 95 and the second wall 100, by means of the tab 475, 480, by an additional means in the z-direction, thereby ensuring the separation of the cable harness 10 from the holder 75 and from the first mold 80. The tab 475, 480 also allows the holder 75 itself to be particularly easily pulled out of the mold cavity 110 in the z-direction or inserted into the mold cavity 110.

[0161] Fig. Figure 31 shows a schematic representation of a molding system 70 according to a fourteenth embodiment. The molding system 70 is substantially identical to that shown in the Fig. 2 to 30. In particular, the mold system 70 shown in Fig. 31, the fourteenth embodiment shown is a further development of the Fig. 20 and Fig. 21 shown form system 70.

[0162] The mold system 70 is further developed in that the mold system 70, in addition to the holder 75 described above, has a further holder 485 and, for example, in addition to the first mold 80 and the second mold 85, a third mold 490. The first mold 80 and the second mold 85 are arranged next to one another at an angle to one another. The third mold 490 is designed as a type of distributor and is connected to the first mold 80 and the second mold 85. For example, the first mold 80 and the second mold 85 can be arranged diagonally next to one another on the mounting board 86. The holder 75 is arranged between the first mold 80 and the third mold 490, and the further holder 485 is arranged between the second mold 85 and the third mold 490. The holder 75 and the further holder 485 can be arranged diagonally to one another. In particular, the further holder 485 is designed essentially identically to the holder 75.On one side, the holder 75 and the other holder 485 are connected to each other.

[0163] By connecting the holder 75 to the additional holder 485, the mold system 70 can be manufactured particularly quickly and easily. In particular, when the first mold 80 and the second mold 85 are arranged next to each other at only a short distance, the assembly of the holder 75 and the additional holder 485 is particularly simple and cost-effective thanks to the holder 75 and the additional holder 485 connected to the holder 75.

[0164] The molding system 70 shown in the figures with the holder 75, 485 can effectively prevent the cables 20, 25 from floating during the foaming of the sheathing 30. This ensures a good mechanical, in particular material-to-material, connection of the cables 20, 25 to the cable bundle 15 via the sheathing 30. This makes it possible to provide a particularly robust cable harness 10. Furthermore, complete foam encapsulation of the cables 20, 25 can preferably be achieved. In particular, a targeted positioning of the cable bundle 15 in the sheathing 30 can be ensured during the entire embedding and foam encapsulation of the cable bundle 15 with the sheathing 30. This is also ensured in particular during the insertion of the cables 20, 25 into the molding space 110 and during the foam encapsulation.

[0165] The holder 75, 485 is functionally designed in such a way that it not only ensures the position of the cable bundle 15 with the geometry described above, but also acts as a type of seal at the end of the mold 80, 85, 490 and thereby prevents the material for the sheathing 30 introduced into the mold space 110 from escaping at the end of the mold 80, 85, 490.

[0166] The Fig. The respective configuration shown in Figures 20 to 23 ensures a multi-section routing of the cable bundle 15. In particular, the cable bundle 15 can be divided into several individual bundles, so that the cable harness 10 is particularly well deformable in this area.

[0167] Fig. 32 shows a perspective view of a molding system 70 according to a fifteenth embodiment.

[0168] The mold system 70 is essentially identical to the ones described in the Fig. 2 to 31 shown form systems 70. In the following, only the differences of the Fig. 32 shown form system 70 compared to the one shown in the Fig. The form system 70 shown in Figures 2 to 5 is discussed.

[0169] The holder 75 is arranged between the first mold 80 and the second mold 85. The first mold 80 has a first end face 505. The first end face 505 can be flat and extend in a yz plane. Longitudinally opposite the first end face 505, the second mold 85 has a second end face 510. The second end face 510 is aligned parallel to the first end face 505. The holder 75 is arranged in a gap between the first end face 505 and the second end face 510. The holder 75 rests against both the first end face 505 of the first mold 80 and the second end face 510 of the second mold 85. The plate-shaped design and the essentially constant thickness of the holder 75 in the longitudinal direction ensure that the holder 75 rests securely and flatly on both the first end face 505 and the second end face 510.

[0170] In order to connect the first mold 80 to the second mold 85 in a form-fitting manner and, if necessary, additionally in a force-fitting manner, the mold system 70 has a connecting means 500.

[0171] Fig. 33 shows that in Fig. 32 shows the mold system 70 according to the fifteenth embodiment in a partially assembled state.

[0172] The connecting means 500 has at least one engagement element 515 and an engagement element receptacle 520. The engagement element 515 is arranged on the first end face 505 of the first mold 80 and connected to the first mold 80. In the embodiment, the engagement element 515 is, for example, pin-shaped and / or bolt-shaped and extends parallel to the x-axis.

[0173] In the embodiment, Fig. 33, for example, two engagement elements 515 are provided, which are arranged, for example, at the same height in the z-direction. Preferably, the engagement element 515 is arranged between the mold cavity 110 and a bottom side 530 of the first mold 80. Laterally, in the transverse direction, the engagement element 515 can be arranged offset inward relative to the side surfaces 135, 140.

[0174] The engagement element 515 may, for example, have a circular or elliptical or polygonal or rectangular cross-section.

[0175] The holder 75 has at least one through-opening 525. The through-opening 525 is configured to correspond to the cross-section of the respectively associated engagement element 515. In the assembled state of the holder 75, the engagement element 515 extends through the respectively associated through-opening 525 such that the engagement element 515 protrudes beyond the holder 75 on a side of the holder 75 facing away from the first end face 505. In other words, the engagement element 515 is configured to be longer in the longitudinal direction than the thickness of the holder 75 in the longitudinal direction.

[0176] The second mold 85 has the engagement element receptacle 520 on the second end face 510, respectively associated with the engagement element 515. The engagement element receptacle 520 can be configured to correspond, at least in sections, to the engagement element 515.

[0177] Analogous to a number of engagement elements 515, a number of engagement element receptacles 520 are also selected. The arrangement of the engagement element receptacles 520 is selected such that the mold space 110 of the first mold 80 is aligned with the mold space 110 of the second mold 85.

[0178] The engagement element 515 can be selected for the engagement element receptacle 520 such that the engagement element 515 and the engagement element receptacle 520 form not only a positive connection but also a press-fit and / or friction-fit connection in order to mechanically connect the first mold 80 to the second mold 85 via the connecting means 500.

[0179] Furthermore, by the engagement element 515 passing through the through-opening 525, the holder 75 is additionally fixed to the mold 80, 85, so that when the finished cable harness 10 is removed in the fourth method step 220, it is ensured that the holder 75 remains on the mold 80, 85 and the cable harness 10 can be removed from the holding space 130, 325, 330 in a simple manner.

[0180] Fig. 34 shows a schematic representation of a molding system 70 according to a sixteenth embodiment for producing the wiring harness 10.

[0181] The mold system 70 is essentially identical to that used in the Fig. 2 to 33 form system 70. The following will focus exclusively on the differences of the Fig. 34 shown form system 70 compared to the one shown in the Fig. The form system 70 shown in Figures 2 to 5 is discussed.

[0182] The holder 75 is arranged at the end of the first mold 80, so that the arrangement of the holder 75 between the first mold 80 and the second mold 85 is omitted. The holder 75 is exemplary as shown in the Fig. 13 and Fig. 14. Due to the end-side arrangement of the holder 75, the holder 75 assumes a sealing function and essentially prevents the material introduced into the mold cavity 110 for producing the casing 30 from escaping.

[0183] Fig. 35 shows a perspective view of a molding system 70 according to a seventeenth embodiment for producing the wire harness 10.

[0184] The mold system 70 is essentially a combination of the Fig. 34 explained mold system 70 according to the sixteenth embodiment and the one in Fig. 16A, Fig. 16B. Here, too, the holder 75 is attached as an end-side holder to the first mold 80. The attachment can be made, for example, at the front side of the first mold 80, for example by means of a screw connection. The geometry of the holder 70 is shown in the Fig. 16A, Fig. 16B explained.

[0185] Fig. 36 shows a perspective view of a molding system 70 according to an eighteenth embodiment.

[0186] The Fig. The mold system 70 shown in Figure 36 is essentially identical to that shown in Fig. 34 and Fig. 35 shown mold system 70. Deviating from Fig. 34 and Fig. 35 is the holder 75 as in the Fig. 10 and Fig. 11 described.

[0187] The cable harness 10 shown in the figures further has the advantage that the cable bundle 15 is protected from mechanical impacts. Furthermore, the cable harness 10 can be preformed by the molding system 70, thus ensuring easier installation during final assembly of the vehicle. The holders 75 also ensure a distance between the cable bundle 15 and the outside of the sheath 30, but also to a vehicle body, for example, at least 3 millimeters from the cable bundle 15, so that the cable bundle 15 in particular is protected from sharp edges. Furthermore, the foamed sheath 30 makes the cable harness 10 particularly flexible and significantly more flexible than a cable harness 10 with a wound sheath.Furthermore, by means of the sheath 30 and the compression of the cables 20, 25 to form the cable bundle 15 by means of the holder 75, 485, the weight of the cable harness 10 can be optimized such that the sheath 30 is particularly thin while at the same time the sheathing is optimized.

[0188] The cable harness 10 can be manufactured with different cable bundle cross-sections using the molding system 70 shown in the figures. Furthermore, the constriction 40 on the cable harness 10 can be used to subsequently attach the cable harness 10 to the constriction 40 using additional components, such as clips / retainers, labels, and / or seals.

[0189] Furthermore, the sheath 30 provides reliable rattle protection, protecting the wiring harness 10 from vibrations and a highly electrically conductive part of the cables 20, 25. Furthermore, the constriction 40 can be used to perform an ultrasonic welding connection at the constriction 40 to weld the wiring harness 10. The holder 75, 485 can also be used with the forming system 70 to easily create different wall thicknesses across sections of the wiring harness 10.
