Description

Method for equipping an object with a cable harness formed from at least one flat conductor and electrical / electronic devices connected to it

The invention relates to a method for equipping an object with a cable harness formed from at least one flexible flat conductor and with electrical / electronic devices connected to the at least one flat conductor, and to the use of such a method. The invention further relates to a system with a plurality of electrical / electronic devices, with a cable harness formed from at least one flexible flat conductor and with an object to be fitted with the electrical / electronic devices.

Numerous applications are known in which certain objects are to be equipped with electrical and / or electronic devices and these devices are to be wired to one another or to their external connection to an existing system. If it is provided that the object with its devices should be connected to another unit or an existing system, a connector is also integrated into the electrical wiring. Depending on the design of the object, the devices and the intended assembly method, the object can first be equipped with the at least one flat conductor and then with the devices to be assembled. Electrical contacting of the devices with individual conductors of the line set is carried out using plug-in connectors, the conductor ends of a flat conductor section to be contacted carrying a corresponding plug-in connection part — either designed as a plug part or as a socket part. An electrical connection between the conductors and the electrically conductive parts of the plug-in connection part arranged at the end of a conductor usually takes place via a crimp connection or by a joining process.

As a set of cables, flat conductor ribbon cables - so-called flexible foil conductors - are used increasingly for the assembly of larger objects. When equipping larger objects with the necessary electrical / electronic equipment, for example at a door technology carrier, the handling of the flat cables or the cable harness formed from them is cumbersome considering the desired expansion and extension due to its size and its limp condition. To form such a cable harness, a section of a flat conductor can be cut with the sufficient number of electrical conductors and brought into the desired cable harness shape by bending certain flat conductor branches. However, this process is complex and basically entails the risk that during the manufacture of the kinks for the desired change of direction of a flat conductor branch at the kink point the conductors break. Therefore, the process of kinking or bending must be carried out with special care. The creation of such cable harnesses produced from a larger flat conductor section can only be implemented mechanically with a disproportionately high outlay. In addition, all of the conductors contained therein have the same cross-sectional area, so that it is not possible to assemble them differently between current-carrying lines and signal lines. Furthermore, it is possible to create such a wiring harness to connect individual, possibly also differently dimensioned and assembled flat conductors by means of suitable connections, for example by using jumper connectors, to form the desired wiring harness. For this purpose, however, all of the conductors of the individual flat conductors to be made in electrical connections with one another must be equipped with such connectors.

This problem of the cumbersome handling of such a wiring harness can (theoretically) be avoided if the objects are equipped with the so-called MID technology (Molded Interconnect Device) with the necessary electrical lines. In this method, the conductor tracks are mostly applied to the object via a printing process. Small openings are used to contact devices arranged thereon, into each of which a contact pin is soldered. Such a contact pin can then be contacted by means of a plug connector. However, MID technology is not suitable for equipping larger objects, especially if the cross-sectional area of the conductors used is to be of a certain size, as is the case, for example, with the wiring harness assigned to a door technology support of a motor vehicle. Based on this discussed prior art, the invention is therefore based on the object to provide a method for equipping an object of the type mentioned, which is not only possible for equipping larger objects with different flat conductors to form a cable harness, but which is particularly is simple and can be carried out with just a few procedural steps, even from an economic point of view, even when handling large, slack cable harnesses.

Furthermore, the invention is based on the object of providing a system mentioned at the outset with which even larger objects can be fitted with individually designed cable harnesses formed from flat conductors with simple means and justifiable economic outlay.

The process-related problem is solved by the method characterized in claims 1 or 5. The system-related problem is solved according to the invention in that the object for the formation of a respective connector part for contacting the electrical / electronic devices to be mounted thereon via an element for forming part of the connector and the electrical / electronic devices to be mounted via a corresponding have complementary connector part.

In the method according to the invention according to claim 1, the object itself, for example a door technology support, serves as an assembly table and workpiece support on which at least one flat conductor for forming a cable harness is brought into its intended extension and extension and fixed thereon. Due to the actual formation or deployment of the cable harness in its intended, even large extension on the object itself, isolated handling of the cable harness alone, for example from another base on the object, is avoided. Before arranging the flat conductor on the object, those sections of the flat conductor on which electrical / electronic devices are to be contacted are stripped, expediently only on one side, so that the conductors to be contacted are exposed in the flat conductor section. However, the object serves not only as an assembly table, but also includes elements for forming one part of a connector using the stripped flat conductor sections. When arranged on the object, these sections of the flat conductors extend over such an element. The elements for forming a plug connector can be, for example, a contact web protruding from the object if the object is to have a male plug connection part. In the event that a female connector part is assigned to the object, however, such an element can be a rectangular opening in the object. The electrical / electronic devices used each comprise a complementarily designed plug-in connection part, which is designed as a socket for contacting a male plug-in connection part located on the object or as a male plug-in connection part for insertion into the opening made in the object. In the latter case, the section of the film conductor above the opening is drawn into the opening during the insertion process, so that the opening then forms a socket with the flat conductor section held therein in a loop. The electrical / electronic devices are attached in a suitable manner to the object, which can be realized, for example, by screw connections or clip connections.

The method according to claim 5 differs from the method according to claim 1 in that the wiring harness is not created on the object itself but on an intermediate carrier. It is provided that the surface of the intermediate carrier, on which the arrangement of the mostly several flat conductors is carried out, has a surface which is negative compared to the surface of the object to be fitted. The use of such an intermediate carrier is useful in those cases in which, when arranging and forming the wiring harness to be formed on the object, such process steps are to be carried out which could possibly result in damage to the actual object. For example, the use of an intermediate carrier is suitable if a plurality of individual flat conductors or their electrical conductors contained therein are used to form the desired wiring harness with one another by means of a joining process, for example by laser welding or by ultrasonic welding. ultrasonic welding should be connected. To carry out such a method, access to the joint on both sides is required, so that for this purpose the intermediate carrier can have an opening at these points, which may be undesirable in the case of the object, such as a door technology carrier. By designing the intermediate carrier with a negative complementary to the surface of the actual object to be fitted, the cable harness formed on the intermediate carrier can be transferred to the object in a simple manner by bringing the intermediate carrier together with the cable harness and the object. so that the wire harness formed on the intermediate support is sandwiched between the two elements. The object has suitable connecting means so that the cable harness remains on the object when the two elements are separated from one another. For example, the object can have adhesive points to which the flat conductor adheres. Other connection techniques, for example latching or clip connections, are also conceivable.

In the method according to claim 5, so to speak, a transfer takes place between the cable harness located on the intermediate carrier and brought into its final extension and the actual object to be fitted. Thus, the intermediate carrier as a tool for equipping the object designed as a molded part. It can also be provided that those electrical / electronic devices with which the object or the molded part are subsequently to be equipped are arranged on the intermediate carrier. Such an arrangement appears to be particularly expedient when an object is to be loaded in several levels one above the other, since a working basis is then provided by the intermediate carrier and transfer to the object only takes place when this layer has been fully assembled and wired is.

In particular in the case of a three-dimensional trunk tree design, the intermediate carrier can also be used to bring the wiring harness into its corresponding three-dimensional configuration during the transfer process, after it has previously reached its intended extent in the plane of the intermediate carrier. kung has been brought. The assembly process is then used simultaneously to deform the wiring harness in the third dimension.

Also in the method according to claim 5 using an intermediate carrier, the plug connection parts for contacting the electrical / electronic devices are expediently provided, including the flat conductors, on the object equipped with the wiring harness. Depending on the configuration of the plug-in connection part assigned to the object, the intermediate carrier has corresponding negative structures.

The description of the claimed methods makes it clear that they are suitable for equipping objects with electrical / electronic devices arranged thereon if the wiring harness is to be produced from several individual flat conductors. The sections provided for connecting the electrical conductors of the individual flat conductors, which are connected to one another, for example, by a joining process, have been stripped accordingly beforehand and arranged overlapping on the object or the intermediate carrier in these areas, so that, for example, one for feeding the individual joining points Ultrasonic welding machines the object or the intermediate carrier is fed as a stable work surface and not individual ends or sections of the flexible film conductor. The arrangement of the individual sections on the object or the intermediate carrier is particularly advantageous when angled, in particular angled, outlets are to be produced from a central flat conductor section, since the individual flat conductor sections are already in their intended arrangement and in this arrangement the automatic joining machine can be supplied. The outlets, which are not carried out in the intended angle, lead to the fact that the outgoing flat conductor branch must be bent to reach the electrical / electronic device to be contacted, so that it no longer lies flat on the surface of the object. However, this is prevented with the method according to the invention.

By providing a working basis on which the wiring harness is brought into its intended configuration - for example the object itself or the intermediate carrier - the individual steps of the method can also take place at different locations and without a time connection, since the cable harness or its individual flat conductor sections are fixed to the object or the intermediate carrier.

The methods according to the invention are particularly suitable for equipping larger objects with decentrally arranged electrical / electronic devices in the manner claimed. For this reason, a preferred use of these methods is aimed at equipping a door technology support for a door of a motor vehicle.

The claimed assembly system includes, in addition to the necessary electrical / electronic devices and the flexible flat conductors for forming the wiring harness as the core, the object to be assembled itself, which, in order to provide contacting of the devices with the flat conductors, elements for forming part of a plug-in connection part, each including a flat conductor section having. The element assigned to the object can, for example, be designed as a contact web protruding from its surface if the devices are to be contacted with a male plug connection part. However, if the devices are to be contacted with a female plug connection part, the object has corresponding openings, into which a male plug connection part of a device can be inserted and takes the flat conductor section located above the opening with it during this insertion process. Through this measure, the devices are contacted directly by the electrical conductors contained in a flat conductor branch, without these having to be additionally equipped with corresponding plug parts. Correspondingly, this contacting has fewer electrical transitions compared to the previously known prior art.

The system can further comprise an intermediate carrier with a surface that is negative relative to the surface of the object to be fitted, on which the arrangement and formation of the cable harness formed from individual flat conductors takes place.

A method for equipping a carrier with decentrally arranged Electrical / electronic devices and with a cable harness formed from individual flexible flat conductor sections is shown in FIG. 1 in two different variations, the method in the left column of FIG. 1 providing a carrier on which all the method steps are carried out, while that shown in the right column Procedure uses an intermediate carrier.

In a first step, the first-mentioned method comprises the provision of appropriately assembled flat conductor sections Fi-F ₄ and a carrier 1 which can be, for example, a door technology carrier (cf. FIG. 2). The flat conductor sections F ₁ - F ₄ are flexible foil conductors, in which copper conductors arranged parallel and at a distance from one another are contained between two polyester foils serving as insulators, and which have been unrolled and cut to length from commercially available rolls. The flat conductor sections F ₂ - F ₄ are stripped at their two ends on opposite upper sides, so that the conductors contained in the flat conductor sections F ₂ - F ₄ are exposed on the respective surfaces. The flat conductor section F ₁ serves as the main line of a cable harness 2 to be created from the flat conductor sections F ₁ - F ₄ and is stripped on the upper side in the area of those sections in which the outlets for the flat conductor sections F ₂ - F _{4 are} provided with respect to those conductors that the conductors contained in the outgoing flat conductor sections F ₂ - F ₄ are to make electrical contact. The carrier 1 comprises three openings D, which are provided for engaging a welding apparatus. Furthermore, the carrier 1 includes the aforementioned positions P ₁ - P ₃ , at which three electrical / electronic devices are to be positioned. In each assembly position P ₁ - P ₃ , a contact web K ₁ - K ₃ is arranged so as to protrude from the surface of the rigid flat plate. The contact webs K ₁ - K ₃ serve - as explained further below - to form a male plug-in connection part, taking into account the stripped ends of the flat conductor sections F ₂ - F ₄ .

After the appropriately assembled flat conductor sections F ₁ - F ₄ and the carrier 1 have been provided, the carrier 1 is then fitted with the individual flat conductor sections F ₁ - F ₄ (cf. FIG. 3). First, the flat conductor section F ₁ with its stripped sections points from the surface of the carrier 1 to the carrier 1 hung up. In this case, the flat line section Fi is arranged over the openings D of the carrier 1 in such a way that the sections stripped on the upper side are arranged within the openings D. The further flat conductor sections F ₂ - F serve to implement outgoings from the flat conductor section F- |. The flat conductor sections F ₂ - F ₄ are arranged with their sections stripped to form the plug-in connection parts with the contact webs Ki-K ₃ facing upward on the carrier 1 and overlapping the flat conductor section Fi. The conductors of the flat conductor sections F ₂ -F _{4 which} are exposed on the underside now lie on the predetermined exposed conductors of the flat conductor section F ₁ .

To connect the conductors of the flat conductor section F ₁ to those of the flat conductor sections F ₂ - F ₄ , the carrier 1 is now fed to an automatic welding machine in which the conductors associated with an opening D are successively welded. Depending on the desired joining process, a solder paste is applied to the carrier 1 with the flat conductor section F ₁ and before arranging the flat conductor sections F ₂ - F4 serving as outlets on the exposed conductors of the flat conductor section F ₁ .

After the electrical conductors have been contacted, the cable harness 2 formed from the individual flat conductor sections F ₁ - F _{4 is} completed. The flat conductor section F _{1 has} already been equipped with a plug part 3 for connecting the cable harness 2.

The individual flat conductor sections F ₁ - F ₄ are expediently fixed on the carrier 1, for example by adhesive points or clip or snap connections, this fixing having already been carried out when the individual flat conductor sections F ₁ - F _{4 were arranged} on the carrier 1.

In the illustration of the free end of the flat conductor section F ₃ , enlarged in FIG. 4, the arrangement of the flat conductor section F ₃ stripped on the upper side to the contact pin K ₂ underneath is shown; the same applies to the ends of the further flat conductor sections F ₂ and F ₄ . The longitudinal section shown in FIG. 5 of the arrangement in FIG. 4 makes it clear that the stripped end of the flat conductor section F ₃ surrounds the contact web K ₂ projecting upward from the carrier 1, so that In this way, a male connector part is created with four adjacent contact tongues formed by the conductor L of the flat conductor section F ₃ . The underside of the flat conductor section F _{3 can be connected} to the contact web K ₂ , for example, by adhesive bonding or by a retaining ring which is fastened, for example, in the region of the fillet. As will be apparent from the description of the subsequent assembly of the carrier plate 1, it is only necessary to ensure with this connection that the section of the flat conductor section F ₃ surrounding the contact web K ₂ remains approximately in the position shown in FIG.

The carrier 1 equipped in this way with the cable harness 2 is then equipped with the electrical / electronic devices provided for the positions P ₁ - P ₃ (see below for FIGS. 9 and 10).

In order to reach this process step, for example in the event that openings as described for the exemplary embodiment in FIGS. 1 to 5 are not provided in the carrier, an intermediate carrier 4, as shown in FIG. 6, can be used, on which the An order and the assembly of a wiring harness 5 takes place. The surface provided for fitting the intermediate carrier 4 represents the negative form to the surface of the actual object to be fitted, which is a door technology carrier 6 in this exemplary embodiment. Since a transfer of the formed cable harness 5 from the intermediate carrier 4 to the door technology carrier 6 is provided as part of this method, the necessary arrangements on the intermediate carrier 4 are also provided in mirror-inverted fashion compared to the arrangement on the door technology carrier 6. The intermediate carrier 4 also includes openings D 'for attaching an automatic welding machine. At those points where male plug-in connection parts are to be formed on the door technology support 6, including the free ends of flat conductor sections, the intermediate support 4 has mounting slots Mi - M ₃ . Flat conductor sections FT-F ₄ 'are also used to equip the intermediate carrier ₄ . In contrast to a fixation of the individual flat conductor sections F ₁ - F4 in their arrangement on the carrier 1, when using the intermediate carrier 4, the flat conductor sections FT - F ₄ 'are only fixed on the intermediate carrier 4 to such an extent that they readily pass in the subsequent step of the transfer be released from the intermediate carrier 4 again can. The arrangement of the flat conductor sections FT-F ₄ '(cf. FIG. 7) is carried out in accordance with the exemplary embodiment described above, the flat conductor sections F ₂ ' - F ₄ 'coming from the flat conductor section FT being stripped at their two ends on the same upper side, on the one hand to contact the corresponding conductors in the flat conductor section F ₁ 'and, on the other hand, to be able to form the desired connector part.

The electrical connection between conductors of the flat conductor section F ₁ 'and the conductors of the flat conductor sections F ₂ ' - F ₄ 'is then established by a joining process.

The transfer of the now completed cable harness 5 to the door technology support 6 is shown in an enlargement of the area of the mounting slot M ₂ in FIGS. 8a to 8d. The cable harness 5 is transferred to the door technology support 6 by merging the intermediate support 4 with the cable harness 5 and the door technology support 6, as can be seen schematically in FIG. 8b. The door technology support 6 comprises a contact web K ₄ , the two lateral surfaces of which are each coated with an adhesive point KL; Another adhesive point KL is located on the underside of the door technology support 6 in the area of the foil conductor section F ₃ 'to be placed. The assembly slot M _{2 of} the intermediate carrier 4 represents a matrix for the contact web K ₄ , into which the contact web K4 is inserted as an associated male part when the intermediate carrier 4 and door technology carrier 6 are brought together. During this process of inserting the contact web K ₄ into the assembly slot M ₂ , the end section of the foil conductor section F ₃ 'with its exposed conductors L is placed around the contact web K _{4 of} the door technology support 6, as shown in FIG. 8c.

After the adhesive of the adhesive points KL has hardened, the intermediate carrier 4 is then removed from the door technology carrier 6, so that the cable harness 5 is now fastened to the door technology carrier 6 to form the desired male plug connection parts S _M. The door technology support 6 is then ready to be equipped with the necessary electrical / electronic devices.

Equipping the door technology support 6 - the same applies to the Carrier 1 - is carried out with devices which each have a connector part Sw designed to complement the male connector part SM formed on the door technology carrier 6. A female counterpart Sw with corresponding contact lamellae is placed on the male plug connection part SM and, under a certain prestress, bears against the top of the exposed conductor L of the male plug connection part SM. The device is identified in FIG. 9 by reference number 7 and is only shown schematically. The device 7 rests on the door technology support 6 and comprises a cable inlet duct 8 for bridging the flat conductor section F ₃ '. The device 7 is positioned at the position corresponding to the position P ₂ in FIG. 2 on the door technology support 6. The device 7 is connected to the door technology support 6 by a plurality of clip-like catches.

Figure 10 shows schematically the door technology carrier 6 fully equipped with the wiring harness 5 and the devices 7, 9, 10. The door technology carrier 6, which is dimensionally stable and rigid, subsequently also serves as a transport and storage module for the before it is installed in the door of a motor vehicle entire arrangement. If the described method is carried out without using an intermediate carrier, the carrier also serves as an assembly table. The simultaneous formation of the connector parts assigned to the support 1 or the door technology support 6, the exposed L of the flat conductor sections F ₂ - F4 or F ₂ - F4 'forming the contact parts of the connector parts, also saves the connection of own connector parts at the free ends the flat conductor sections. From the description it is also clear that an assembly of the electrical / electronic devices 7, 9, 10 is very simple, automatically with the described locking attachment of the devices 7, 9, 10, for example on the door support 6, the electrical connection by inserting the male Plug connector part S in the corresponding counterpart Sw.

The method described is suitable on the basis of the method steps to be carried out with simple movements, in particular also for implementation in a production line. Reference numerals list
