Description

[0001] The invention relates to a holding device and an assembly device comprising such a holding device, particularly for the automated production of a preferably electrical wiring harness. The invention further relates to a method for producing such a wiring harness using such a holding device. The holding device generally comprises a base body extending in a longitudinal direction, which has a holding region for receiving a connection component arranged at the end of the wiring harness.

[0002] The wiring harness typically comprises a plurality of individual wiring components, in particular individual electrical wires. The wiring harness is preferably branched and forms a cable harness. The wiring harness is intended for installation in a motor vehicle and, in the installed state, is arranged in such a motor vehicle.

[0003] DE 10 2017 206 139 A1 and DE 10 2017 206 140 A1 each describe methods for the automated production of a cable harness. Among other things, this involves the connectors attached to the ends of partial strands of the cable harness being picked up in a holding device known as a transporter and moved along rails to form the cable harness into a desired branched structure. In a subsequent process step, for example, the individual wires are collectively wrapped in a banding.

[0004] DE 10 2022 101 493 A1 describes a manufacturing device for producing a wiring harness, in which the wiring harness is secured to a frame unit using holding devices. The connectors attached to the ends of each wiring harness are held to the frame, for example, by a tension spring, so that the individual strands are kept taut. Wrapping and banding of the strands is also provided here.

[0005] Especially when the cable harness is wrapped, it is subjected to mechanical stress and tensile stresses can occur, which can lead to a load on the cable ends connected to contact elements in the plug, so that there is a risk of impairing the contact of the cable ends.

[0006] Based on this, the invention is based on the object of enabling a particularly automated production of, in particular, electrical cable harnesses, in which the manufactured cable harness meets predetermined quality criteria and in which, in particular, a reliable contact connection of the cable ends is ensured.

[0007] The object is achieved according to the invention by a holding device having the features of claim 1, which is designed and used for the particularly automated production of a preferably electrical wiring harness. The wiring harness typically comprises a plurality of electrical wiring components, such as individual electrical wires. The object is further achieved according to the invention by an assembly device having at least one such holding device and by a method for producing such a wiring harness.

[0008] The preferred embodiments listed below with regard to the holding device are also to be transferred analogously to the mounting device and the method and vice versa.

[0009] The cable harness is in particular a branched cable harness, also referred to as a cable set or wiring harness. Besides electrical cable components, the cable harness preferably does not have any further cable components. Alternatively or additionally, it has optical lines or fluid lines. A connection component, in particular an electrical plug, is attached to at least one end and preferably to several ends of the cable harness. The plug generally has a plug housing with contact elements embedded therein, for example crimp contacts, to which the cable ends of the individual cable components are electrically contacted. Alternatively, particularly in the case of non-electrical cable types, the connection component is another contact element or other connection components, couplings or fittings.In general, the connection component is used to connect the cable harness to another, in particular electrical, component, which in turn is, for example, a cable harness or an electrical device.

[0010] The holding device has a base body that extends from a rear end to a front end in a longitudinal direction. The longitudinal direction corresponds to the longitudinal direction of the cable harness or the longitudinal direction of a sub-harness connected to the connection component.

[0011] A holder is arranged in the base body, which has a holding area for temporarily securing the connection component. When the cable harness is inserted into the holder, it extends longitudinally from the connection component and thus toward the front end of the base body, exiting the base body and thus extending beyond it.

[0012] For temporary fixation, a holding element is preferably provided, which can be releasably attached to the holder, so that the connection component can be inserted into the holder and secured therein. The holding element is, for example, a type of cover or a clamping tab, which covers at least part of the preferably upwardly open holding area and thereby secures the connection component in the holding area.

[0013] In order to ensure a specified quality of the cable harness during the particularly automated production of the cable harness, especially for example when wrapping the cable harness with a banding, and in particular to avoid damage, for example as a result of tensile stresses during wrapping, at least one and preferably both of the following measures are provided: a) The holder is elastically mounted on the base body and can be moved longitudinally, i.e. from the rear end to the front end, and is counteracted by a spring force. The spring force therefore acts counter to the longitudinal direction. When the cable harness is inserted, a tensile force is exerted on the holder counter to the longitudinal direction and counter to the spring force. The cable harness is typically held taut at its ends by suitable holding elements. The spring force can be exerted mechanically, pneumatically, or hydraulically. Preferably, it is exerted mechanically, and at least one spring element is arranged. This is designed, for example, as a compression spring or a tension spring. The base body forms, in particular, a type of guide channel for the holder, which, viewed in cross-section, is, for example, U-shaped. The holder is inserted in this guide channel with a particular fit.The elastic mounting of the holder absorbs tensile forces that occur during production and thus at least relieves the connection component of such tensile stresses, so that the stress is lower and the risk of damage to the connection component, in particular the risk of impairment of the contact connection between the cable ends and the contact elements, is at least reduced. b) A releasable securing element is attached which limits or prevents longitudinal movement of the connection component and in particular of the holder until a predetermined force acting on the securing element, in particular in the longitudinal direction, is exceeded. In this case, the securing element is triggered. The force is generated by a tensile force acting on the cable harness and thus on the connection components, via which the connection component and with it the holder is pulled longitudinally.The securing element is therefore a releasable lock for the longitudinal movement of the connecting component and, in particular, also of the holder in the longitudinal direction. When the securing element is triggered, this lock is released and the connecting component and, preferably, the entire holder can be moved (further) in the longitudinal direction. The triggering of the securing element therefore indicates that a maximum permissible tensile stress has been exceeded. The triggering of the securing element can be recorded, in particular retrospectively, so that the exceeding of a specified tensile stress is recorded. A corresponding cable harness can be rejected as part of a quality control process or at least subjected to a re-inspection to ensure the desired quality requirements.

[0014] In both cases, the holding device itself is designed to ensure the desired quality of the cable harness. For this purpose, the holder is arranged within the base body so that it can be moved against the spring force, and / or the locking element is part of the holding device, which is triggered when the connection component or the holder is pulled with excessive force against the barrier formed by the locking element.

[0015] In a preferred embodiment, both variants are combined. This means that the holder is mounted against the elastic spring force and simultaneously triggers the locking element when a predetermined tensile force is exceeded.

[0016] In both variants, the holder does not necessarily have to be permanently in contact with the securing element. Alternatively, in an unloaded state, the holder is initially spaced from the securing element and only comes into (temporary) contact with the securing element when tensile load is applied.

[0017] The mounting device according to the invention comprises at least one such holding device. The cable harness is generally held on the mounting device, with at least one end of the cable harness resting in such a mounting device.

[0018] The mounting device preferably comprises a support, which is designed, for example, as a frame or a mounting board, on which several retaining elements are mounted, for example, protruding from the mounting board, which fix and hold the cable harness, in particular according to a predetermined, branched installation geometry. The retaining elements are typically designed like pins or forks, so that the cable harness is held at a higher level, spaced from the support. This allows the individual components of the cable harness to be surrounded by banding.

[0019] The holding device is therefore generally designed solely to hold the connection component attached to the end of the cable harness. In particular, it is designed solely to hold a single connection component. Specifically, the holding device is designed for attachment to a pin-shaped holding element, for example, of such a mounting device.

[0020] The cable harness is, in particular, a branched cable harness with several sub-strands. Sub-strands typically branch off from a main strand. Specifically, it is an at least partially pre-assembled cable set, with connection components, in particular connectors, attached to the ends of the sub-strands. Preferably, at least one such holding device is assigned to each sub-strand. The elastically mounted holder exerts a tensioning force on the holder, and thus, via the connection component, on the cable harness, for a particular sub-strand or the cable harness as a whole. This keeps the cable harness taut. At the same time, the elastic mounting serves to compensate for length tolerances.

[0021] During the manufacturing process, the cable harness with its end-mounted connection component, in particular a plug, is inserted into the holding device. In a branched cable harness, several ends of the branched cable harness are each inserted into a holding device. When a tensile load is applied to the cable harness, in the first variant the holder is elastically displaced longitudinally within the body against the spring force. Alternatively or additionally, a securing element is attached to the base body, which is triggered when the specified (tensile) force acting on the securing element in the longitudinal direction is exceeded. The force is exerted as a result of the tensile load acting on the cable harness.

[0022] The base body preferably has a front wall against which the holder can be moved longitudinally. The front wall thus forms a longitudinally acting barrier for the holder.

[0023] Preferably, at least one spring element is arranged between the front wall and the holder. This spring element is a compression spring. Alternatively, a tension spring can also be arranged between the holder and a rear region of the base body.

[0024] The holder is preferably arranged like a slide, allowing it to be moved linearly within the base body. For this purpose, the base body, for example, forms guide structures.

[0025] In a preferred embodiment, the holder and especially the carriage can be displaced along at least one guide pin, wherein the spring element is arranged around the guide pin.

[0026] The guide pin is conveniently located in the front wall, ensuring reliable guidance of the holder.

[0027] In a practical embodiment, the front wall is part of the aforementioned securing element and is detachably attached to the base body. This means that when the specified tensile force is exceeded, the front wall is detached from the base body and releases the holder, so that it no longer forms a barrier to the holder's longitudinal movement. In particular, the connecting component is firmly fixed in the holder's receiving area and does not leave the holder.

[0028] In an alternative embodiment, the holder itself has such a front, detachable wall, which is detachable and part of the securing element. In this case, if the specified force is exceeded, the connecting component is released from the holder and can leave it.

[0029] In general, in such an alternative design, the securing element is attached to the holder and, when the specified force is exceeded, (only) releases the connecting component so that it can leave the holder.

[0030] In the design in which the movement of the holder is limited by the locking element until the specified force is reached, the locking element is attached to the base body.

[0031] In a preferred embodiment, the securing element has a releasable locking element, which is preferably oriented transversely to the longitudinal direction and thus acts transversely to the longitudinal direction. This locking element is released when the specified tensile force is exceeded, thus releasing the displacement path for the holder or the connecting component when triggered.

[0032] The locking element can be electrical, magnetic, pneumatic, or, in particular, mechanical. With a magnetic locking element, the securing element is held in the desired locking position, for example, by a magnetic force.

[0033] According to a first variant, the locking element is triggered in a controlled manner, particularly when, for example, an excessive tensile load is detected. This is actively detected, for example, using a suitable sensor element, such as a force sensor. The locking element is then released via a corresponding control signal.

[0034] Alternatively, such active control and detection of the tensile load is dispensed with, and the releasable locking element operates purely passively. This means that the locking element is automatically released by the force acting on it in the longitudinal direction if this force exceeds a predetermined value.

[0035] In one embodiment, the locking element directly forms the securing element. The locking element is designed, for example, like a barrier or bolt, which forms the barrier for the holder or connecting component.

[0036] Preferably, the locking element has a (transversely) displaceable locking bar, by means of which the securing element is held on the base body until the predetermined tensile force is exceeded.

[0037] The locking bolt is preferably held elastically in the transverse direction, in particular mechanically counteracting the spring force of a locking spring.

[0038] Preferably, the front wall is releasably secured to the base body via the locking bar. In this case, the locking bar and the front wall form the securing element. Alternatively, a front wall of the holder is releasably secured to the rest of the holder via the locking bar.

[0039] The at least one locking element and in particular the at least one locking bolt are preferably integrated in the base body and engage resiliently in the front wall. Alternatively, they are integrated in the front wall and engage resiliently in the base body. Specifically, at least one locking element is arranged on each of the opposite edge-side end faces of the front wall. For this purpose, bores are drilled into the front wall from the end faces, into which bores the locking bolt, designed, for example, in the manner of a locking pin, engages under spring load. A front end of the locking bolt is suitably designed, for example, to be bevelled or rounded, so that a force acting in the longitudinal direction generates a radial force component that pushes the locking bolt radially away, thereby releasing the lock.

[0040] The front wall is preferably connected to the base body via a securing thread, so that if the front wall is released and separated from the base body, it remains connected to the base body via the securing thread and is not pushed out into the room uncontrollably upon release. In the version where a front wall of the holder is detachable, it is connected to the rest of the holder via the securing thread.

[0041] The front wall can be easily reinserted into the base body after a release. The front wall is reversibly attached to the base body, allowing the holding device to be refitted and used again even after a release.

[0042] The spring force for the elastic mounting of the holder is selected and the locking element is designed in such a way that it only triggers when a certain value of the spring force is exceeded. In the design with the spring element to exert the spring force, for example, the spring hardness of the spring element is suitably selected so that the holder can initially be moved longitudinally until the spring force exceeds the specified tensile force. Alternatively, it is also possible for the spring hardness of the spring element to be so low that the spring force generated by the spring element never exceeds the specified tensile force. Instead, in this case, the holder moves to an end position in which, for example, the spring element is fully compressed, and then presses on the locking element.

[0043] In a preferred embodiment, the holding device is designed such that, in the event of a safety element being triggered, the holder leaves the base body. The holder is therefore pulled out of the base body by the exerted tensile force. Exceeding the maximum permissible tensile force can therefore be easily detected immediately, since the holder is no longer in the base body.

[0044] Alternatively, the holder remains within the base body even after the locking element is released. The release of the locking element can be detected because the locking element, and especially the front wall, is no longer held to the base body. In this variant, a stop is designed to prevent the holder from leaving the base body. The stop is located in the travel path of the holder.

[0045] According to a preferred variant, the base body has a first guide element, preferably designed as a guide groove. The holder has a second guide element, preferably designed as a guide web or guide knob, which is formed in particular on the side or bottom of the holder. The two guide elements form, in particular, a linear guide.

[0046] Preferably, the stop is arranged in the guide groove, for example, at a front end of the base body. Specifically, the previously described locking element, in particular the locking bolt, forms the stop. The locking element therefore engages in the guide groove and forms the stop.

[0047] The guide web or a guide knob is preferably formed only in a rear part of the holder, so that in the event of triggering, the holder can slide at least a short distance over the barrier formed by the safety element, but is still held in the base body and cannot fall out of it.

[0048] In both cases, i.e. both in the variant in which the holder leaves the base body and in the variant in which it remains in the base body, the holder can be reversibly inserted back into the base body, in particular into a defined starting position, so that it can be used again.

[0049] An embodiment of the invention is explained in more detail below with reference to the figures, which show, in simplified representations: FIG 1 a perspective view of a holding device with a connecting component inserted therein, which is designed as a plug, FIG 2 a longitudinal section through the holding device according to FIG 1 , without connection component, FIG 3 a cross section through the holding device according to FIG 1 in the area of ​​a front wall, which is also designed as a securing element, FIG 4 a plan view of a schematically illustrated mounting device.

[0050] One in the Figures 1 to 3 The holding device 2 shown has a base body 4 and a holder 6 displaceably mounted therein in a longitudinal direction L. The holder 6 has a holding area 8 which is used to receive and fix a connection component 10 (see FIG 1), in particular a plug, specifically a plug housing. In the exemplary embodiment, the connection component 10 is secured by a holding element 12 in the holding area 8, which in the exemplary embodiment is open at the top. The holding area 8 fixes the connection component 10 in the longitudinal direction L in a form-fitting manner, so that when a tensile force acts on the connection component 10 in the longitudinal direction L, this tensile force is transferred to the holder 6. The holding element 12 can be detachably fixed to the holder 6. It covers a partial area of ​​the holding area 8 and is fastened to the holder 6, for example, with a screw.

[0051] The base body 4 extends in the longitudinal direction L from a rear end 4A to a front end 4B. In the exemplary embodiment, the base body 4 forms a guide channel for the holder 6, in which the latter is guided in a particularly precise manner. Specifically, the base body 4 has a U-shaped cross-section, and the holder 6 is arranged within the open U-shaped area.

[0052] At the front end 4B, a front wall 14 is attached as a separate element, which closes the guide channel formed by the base body 4 to the front in the longitudinal direction L. According to the illustrated embodiment, the front wall 14 is arranged to be detachable, specifically in such a way that it is released when a predetermined force acting in the longitudinal direction L is exceeded, so that it is separated from the base body 4. In this respect, this front wall 14 forms a partial element of a securing element 16, which is triggered when a predetermined (tensile) force acting on the holder 6 and acting in the longitudinal direction L is exceeded.

[0053] The holder 6 preferably has a cross-sectional contour complementary to the guide channel of the base body 4. In particular, the base body 4 and thus the guide channel have at least one guide groove 17 or alternatively a guide web as the first guide element, which is arranged, for example, on the bottom side or on the edge side. According to the Figures 1 to 3 Two opposing edge-side guide grooves 17 are formed. Correspondingly, the holder 6 preferably has at least one complementary guide web or guide groove as a second guide element (not visible in the figures).

[0054] Alternatively or additionally - as shown in the exemplary embodiment - the holder 6 is guided along preferably two guide pins 18 which extend in the longitudinal direction L. As can be seen in particular from the FIG 2As can be seen, a respective guide pin 18 is mounted in a bore of the holder 6 with one end and with its other end in a respective bore in the front wall 14. A spring element 20 designed as a compression spring is arranged around a respective guide pin 18, so that it acts between the front wall 6B and the holder 6 and exerts a compressive force on it counter to the longitudinal direction L (cf. FIG 2 ). The holder 6 is therefore displaceably mounted within the base body 4 against the elastic restoring force of this spring element 20.

[0055] The front wall 14, as part of the securing element 16, is secured by two opposing locking elements 22 oriented in the transverse direction. These locking elements 22 are designed such that they release the front wall when a predetermined tensile force acting on the holder 6 and thus indirectly also on the front wall 14 is exceeded.

[0056] In the exemplary embodiment, the locking elements 22 have a locking bar 26 which is elastically mounted against a locking spring 24 and which is formed by a ball in the exemplary embodiment. In principle, this could also be designed as a bolt-shaped element. In addition to the locking bar 26 and the locking spring 24, the locking element 22 also has a sleeve 28 which is designed in particular as a screw sleeve which can be screwed from the outside into a corresponding threaded bore in a respective side wall of the base body 4. The locking spring 24 and locking bar 26 are mounted within this sleeve 28. As an alternative to this configuration, the locking bar 26 and locking spring 24 are mounted directly in a blind hole, for example.

[0057] The front wall 6A has an indentation on each of its opposite end walls, for example a blind hole or a depression, into which the ball forming the locking bolt 26 is pressed by means of the locking spring 24. When a force acting in the longitudinal direction L is exceeded, the axial force component is at least partially converted into a radial force component, which presses the locking bolt 26 outwards in the transverse direction, so that the front wall 14 and thus the securing element 16 as a whole are released and thus releases the guide channel for the holder 6.

[0058] In an alternative variant, not shown in detail here, the securing element 16 serves only as a lock for the connection component 10, which in the

[0059] Holding area 8. If the predefined force is exceeded, the securing element 16 is triggered and only releases the connecting component 10 so that it can leave the holding area 8.

[0060] As from FIG 1 or FIG 3 As can be seen, at least one of the locking elements 22 engages in the guide groove 17. This means that the locking element 22 is guided from the side through the wall of the base body 4 and through the guide groove 17. The locking element therefore forms a stop for the holder 6, specifically for the guide web of the holder 6 projecting from the edge. This prevents the holder 6 from falling out of the base body 4 in the event of triggering.

[0061] According to an alternative embodiment, such a stop is omitted, so that in the event of triggering, the holder 6 falls out of the base body 4. For this purpose, the holder 6, for example, does not have a laterally projecting guide web that engages in the guide groove 17.

[0062] According to an alternative embodiment not shown here, the holding device 2 does not have a detachable securing element 16. In particular, the wall 14 is non-detachable and is an integral part of the base body 4. In this variant, the holder 6 is supported only elastically against a spring force, which is exerted in particular by the previously described spring element 20. The holding device 2 is preferably identical or at least largely identical to the embodiment described in the figures, except for the features for the securing element 16 (in particular the detachable wall 14, the locking element 22, and the securing thread 38).

[0063] FIG 4shows a mounting device 30 with a support 32, particularly designed as a laying board. The mounting device 30 serves for assembling a particularly branched cable harness 36. In the exemplary embodiment, this harness has several sub-harnesses that, for example, cross each other. Each sub-harness has, for example, two opposite ends.

[0064] A plurality of holding elements 34 are fastened to the carrier 32, which are designed in particular in the manner of pins or forks projecting upwards from the carrier 32. These are designed to fix one end of the cable strand 36 in place. In the exemplary embodiment, a plug is attached to each cable end as a connection component 10. At one end of each partial strand, the respective connection component 10 is received in the holding device 2 described above. At the other ends, in the exemplary embodiment shown, the connection component 10 is held directly on the respective holding element 34.

[0065] During assembly, the branched cable harness 36, which is designed as a preconfigured cable set, is first attached to the carrier 32. For this purpose, the connection components 10 previously attached to the ends of the cable harness 36 are fastened to the holding elements 34, with at least a portion of the connection component 10 being inserted into a respective holding device 2.

[0066] In a subsequent assembly step, the cable harness 36 undergoes a further assembly step and, in particular, is provided with a banding at least in some areas. For this purpose, a band is wound around a respective section of the cable harness 36 consisting of several individual cable components. This is preferably carried out fully automatically using a suitable winding device. During this process - i.e. generally during the further assembly step - tensile forces are exerted on the cable harness 36. These are at least partially compensated by the elastic mounting of the holders 6. However, if the tensile stress exceeds a predetermined tensile force, the securing element 16 is triggered. In the exemplary embodiment, the front wall 14 is separated from the remaining base body 4. According to a preferred variant, the holder 6 is completely pulled out of the base body 4 due to the exerted tensile force, i.e., is no longer contained in the base body 4.The triggering of the safety element 16 is therefore easily detectable, and such a cable harness 36 can be sent for further processing to ensure the required quality or can be rejected. Alternatively, the holder 6 remains in the base body 6, for example, by being held by the previously described stop formed by the locking element 22.

[0067] The front wall 14 is connected to the base body 4 in particular via a securing thread 38 (cf. FIG 1 ), so that the front wall 14 is held captive on the base body 4 and does not fly around the room in an uncontrolled manner when triggered. List of reference symbols
