Description

Technical Field

[0001] The proposed solution relates to a plug with a circuit board. Here, the plug can be connected to a socket assigned to the plug in order to supply electrical energy and / or electrical signals to the circuit board. Background Art

[0002] Such plugs are known, for example, from the construction of large household appliances and vehicles. To protect the circuit board, the plug may have a housing that substantially surrounds the circuit board. To connect the circuit board to the socket, the housing must have at least one opening. This can reduce the protection of the circuit board from external influences, particularly the protection of the interior space defined by the housing from the intrusion of solid objects and / or liquids. Utility Model Content

[0003] Therefore, there is a need to improve a plug of the type mentioned at the outset with respect to shielding against potentially harmful influences.

[0004] This object is achieved with a plug having a printed circuit board.

[0005] Therefore, the proposed plug can be connected to a socket assigned to the plug in order to supply electrical energy and / or electrical signals to the printed circuit board, wherein:

[0006] the plug comprises a housing which, apart from at least one opening, encloses an interior space,

[0007] - the circuit board is disposed substantially within the interior space and extends through the at least one opening, and

[0008] The printed circuit board has at least one conductor track electrically connectable to the socket, the conductor track extending in a contact section of the printed circuit board adjoining the at least one opening of the housing, wherein the conductor track preferably extends on and / or within the printed circuit board.

[0009] By extending at least one conductor track within the circuit board's contact section, contact between the housing and the at least one conductor track can be avoided. This improves the protection of the at least one conductor track from potentially damaging influences. In particular, material scraping from the at least one conductor track through the housing due to relative movement of the housing relative to the circuit board can be reduced. For example, such relative movement can be caused by mechanically transmitted vibrations to the housing, thermal expansion fluctuations, or manufacturing processes. Therefore, the proposed solution can improve the service life of the circuit board.

[0010] In another embodiment of the proposed solution, the printed circuit board can have multiple, planarly connected layers. At least one conductor track can be extended within the printed circuit board by extending on a surface of one layer facing another layer. This can simplify the production of the printed circuit board and the at least one conductor track extending within the printed circuit board within the contact section.

[0011] Each layer can extend in a planar manner. In particular, each layer can extend within an extension plane. For example, the layers can be bonded, welded, screwed, or riveted to one another. This can reduce manufacturing effort and lower manufacturing costs.

[0012] Each layer can have multiple surfaces. In principle, a multilayer printed circuit board can be realized with different arrangements of the layers relative to each other. This improves the adaptation of the printed circuit board to different geometries of the installation space.

[0013] In a further embodiment of the proposed solution, the layers can be connected to one another along a stacking direction extending perpendicularly to the plane of extension of the layers. This can further reduce the production costs.

[0014] Each extension plane can be assigned a surface normal perpendicular to the respective extension plane. When the layers are connected to one another in the stacking direction, the surface normals of all layers can run parallel to one another. Parallel surface normals can define the stacking direction.

[0015] In another embodiment of the proposed solution, an inner section of at least one conductor track in the region of the contact section can extend over an inner surface of one of the layers. This inner surface can face another of the layers. This can further improve the protection of the at least one conductor track.

[0016] By way of example, a circuit board can have exactly two layers. The interconnected layers can each have an inner surface. The two inner surfaces of these layers can abut against one another. At least one conductor track can extend on one of the inner surfaces of the layers in the region of the contact section of the circuit board. This allows the circuit board and the conductor tracks extending therein to be manufactured from exactly two layers. This reduces material and manufacturing costs.

[0017] In principle, a circuit board can also have multiple conductor tracks. This improves the functionality of the circuit board. The multiple conductor tracks can be distributed over multiple layers. This allows the number of conductor tracks to be increased without falling below a critical spacing between the conductor tracks. This critical spacing can be the spacing at which the breakdown voltage associated with this spacing is not reached during normal operation.

[0018] For example, multiple conductor traces can be distributed across the inner surfaces of multiple layers within the contact section. Electrical insulation issues can arise between conductor traces on inner surfaces of different layers that face each other. For example, the circuit board can be constructed with more than two layers. Thus, the circuit board can have at least two inner surfaces that do not face each other. Consequently, multiple conductor traces can be arranged on these inner surfaces without being in electrical contact with each other.

[0019] By way of example, the layers can be numbered along the stacking direction. Here, the first and nth layers can have one inner surface, while the remaining n-2 layers arranged between the first and nth layers can each have two inner surfaces. Thus, a circuit board with n layers can have 2+(n-2)*2 inner surfaces. At least one conductor track can extend on each of the 2+(n-2)*2 inner surfaces within the contact section. In particular, in the case of multiple conductor tracks, the conductor tracks can be distributed across different inner surfaces within the contact section. This improves the electrical insulation between the conductor tracks within the contact section.

[0020] In a further embodiment of the proposed solution, an outer section of at least one conductor track outside the housing can extend on an outer surface of one of the layers facing away from the other layers. This improves the connectability of the printed circuit board to the socket.

[0021] For example, at least one conductor track extending outside the housing on an outer surface can be configured to electrically couple to a socket connectable to a plug via a spring-loaded contact. To this end, at least one conductor track can itself be configured to have a spring-loaded contact section outside the housing. Alternatively or additionally, at least one conductor track on an outer surface outside the housing can have a flat contact section that can be brought into contact with a spring-loaded contact of the socket. This can improve the reliable connection between the circuit board and the socket.

[0022] In principle, at least one conductor track can also extend on the outer surface within a section of the printed circuit board arranged in the interior of the housing.

[0023] If a circuit board has n layers, the outer surface of the circuit board can be defined by multiple outer sub-surfaces distributed across these layers. If multiple conductor tracks are present, conductor tracks extending on the outer surface outside or inside the housing can extend on outer sub-surfaces of different layers. In the contact section of the circuit board, multiple conductor tracks can extend along one of the inner surfaces. Alternatively, multiple conductor tracks can extend within the circuit board, distributed across multiple inner surfaces. This can further improve electrical insulation.

[0024] In a further embodiment of the proposed solution, at least one conductor track can be designed to connect the outer section to the inner section by means of an electrically conductive plated-through hole extending through one of the layers. This can further improve the reliable and cost-effective production of the circuit board.

[0025] Exemplarily, the plated through hole can be configured as a vertical conductive connection (via). Vias are already known from the manufacture of electronic printed circuit boards. Therefore, by configuring the plated through hole as a via, manufacturing costs can be reduced.

[0026] In a further embodiment of the proposed solution, at least one plated-through hole can extend in the stacking direction through one of the layers. This can simplify production.

[0027] In principle, it is conceivable and feasible for at least one conductor track to extend from the inner surface of one layer to the outer sub-surface of another layer via a plated through-hole. This allows at least one conductor track to extend across layers within the circuit board. In particular, at least one conductor track can extend from the outer sub-surface of one layer via at least one plated through-hole to the inner surface of one of the inner layers arranged between the first and nth layers. This improves the distribution of the multiple conductor tracks within the contact section and, therefore, the electrical insulation of the conductor tracks.

[0028] In another embodiment of the proposed solution, the printed circuit board can include an integrated circuit for adapting the voltage and / or current intensity of the current that can be transmitted via the socket to the at least one conductor track. This allows electrical energy to be tapped on the printed circuit board that is adapted to the specific application.

[0029] Exemplarily, the integrated circuit may include at least one structural element from the following group: a transistor, a capacitor, a coil, a diode.

[0030] In another embodiment of the proposed solution, the integrated circuit can be arranged in the interior space, thereby improving the protection of the components of the circuit.

[0031] In a further embodiment of the proposed solution, the printed circuit board can be configured with an electronic control unit for controlling electrical consumers connectable to the printed circuit board. As a result, the electrical consumers can be coupled to a socket via a durable, inexpensive connection for supplying electrical energy.

[0032] By way of example, the electrical consumer can be designed with an electric motor.

[0033] Furthermore, to protect the printed circuit board, the housing can rest against the printed circuit board in the region of the contact section with the at least one opening. Since the at least one conductor track extends within the printed circuit board within the contact section, the housing can rest against the printed circuit board without simultaneously resting against the at least one conductor track.

[0034] In further embodiments of the proposed solution, the housing can additionally or alternatively have an elastic edge extending along the at least one opening, thereby compensating for manufacturing tolerances and / or thermal dimensional changes and / or improving the sealing of the interior.

[0035] In principle, the housing can have exactly one opening or a plurality of openings. In the case of a housing having a plurality of openings, each of the openings can have a resilient edge. Similarly, the circuit board can extend through the exactly one opening or through a plurality of the openings.

[0036] In further embodiments of the proposed solution, the housing can additionally or alternatively have at least one seal for sealing the interior, thereby further improving the protection of the printed circuit board against the ingress of solid objects and liquids.

[0037] By way of example, the seal can be arranged on the housing in a circumferential manner around the edge of the at least one opening. In a further embodiment of the proposed solution, the at least one seal can extend along the at least one opening in such a manner that the at least one seal rests against an outer surface of the circuit board.

[0038] Additionally or alternatively, at least one seal may be arranged on the circuit board. The seal on the housing and the seal on the circuit board may abut against each other, thereby further improving the protection of the circuit board.

[0039] In an exemplary embodiment of the proposed solution, the housing can be constructed with a plurality of interconnected housing parts, which preferably have seals that are geometrically integrated into the housing parts. This allows the housing parts, when properly connected to one another, to seal the interior space enclosed by the housing parts via the geometrically integrated seals without additional components. This reduces assembly effort and material costs.

[0040] In one embodiment of the proposed solution, the seal on the housing and / or the seal on the printed circuit board can be designed with a labyrinth seal and / or a pinch lip or be arranged thereon. In particular, the housing can be designed with a pinch lip in the region of at least one opening of the housing. Additionally or alternatively, in the case of multi-part production, the housing can be designed with a labyrinth seal along the edges used to join the housing parts together.

[0041] In particular, the geometrically integrated seal can be configured to have a labyrinth seal. For this purpose, the housing portion can have sealing sections which, when the housing portion is assembled as required, can interlock and engage so that the interior space enclosed by the housing portion is sealed.

[0042] In another embodiment of the proposed solution, the circuit board may have a stop that rests against the housing and serves to secure the circuit board relative to the housing. This reduces relative movement of the circuit board relative to the housing and, therefore, damage to the circuit board. Exemplarily, the stop also reduces the intrusion of solid objects and / or liquids into the interior of the housing. The stop can be made of plastic, thereby reducing manufacturing costs. Alternatively, the stop can be made of metal, thereby improving heat dissipation from the circuit board.

[0043] In a further embodiment of the proposed solution, the printed circuit board can have a circumferential contour in the region of the contact section, into which the housing engages for fixing the printed circuit board. This can further improve the damping of relative movements.

[0044] In another embodiment of the proposed solution, the housing can have at least two housing parts, between which the printed circuit board is at least partially enclosed. This allows for good support of the printed circuit board, so that mechanical forces, particularly those occurring when connecting the plug to the socket, can be better dissipated via the housing. It can be particularly advantageous if one housing part rests against the top side of the printed circuit board, while the other housing part rests against the bottom side. It can also be particularly advantageous if the printed circuit board is enclosed by at least two housing parts, at least in the area of the opening, for example, along the edge of the opening.

[0045] In a further embodiment of the proposed solution, the printed circuit board can be fixed by means of at least two housing parts.

[0046] In another embodiment of the proposed solution, the seal can be configured to be plastically deformable and / or elastic in the contact region with the circuit board. Thus, a good sealing effect can be achieved without applying excessive pressure to the circuit board in the contact region.

[0047] In a further embodiment of the proposed solution, the seal can have at least one rib. The at least one rib can be formed and / or arranged on the housing.

[0048] According to a further embodiment, a particularly good and economical sealing of the printed circuit board can be achieved by designing the housing as a two-component component (2K component).

[0049] Can be more advantageously, seal is configured to be breathable and / or not pressure-resistant and / or not waterproof.Preferably, constitute dustproof portion by this seal, can better prevent or avoid dust and other particles from invading in the housing interior by dustproof portion.

[0050] According to another aspect of the proposed solution, the aforementioned object is also achieved by a motor assembly. The proposed motor assembly comprises a motor and a plug connected to the motor according to the proposed solution. The motor can be supplied with electrical energy and / or electrical signals via the plug.

[0051] The proposed plug allows the motor to be supplied with electrical energy via the socket. Furthermore, the proposed plug allows the printed circuit board to be shielded from solid objects and / or liquids. By extending the at least one conductor track within the printed circuit board in the region of the contact section, the at least one conductor track can be protected from harmful effects of the housing on the at least one conductor track.

[0052] In principle, it is conceivable and feasible to arrange the motor outside the housing or inside the housing. Here, the motor can include at least one stator and a rotor.

[0053] In the proposed motor assembly design, the plug housing may have an opening through which a circuit board extends for connecting at least one conductor track to the motor. The at least one conductor track may extend within the circuit board within a contact section of the circuit board adjacent to the opening for the motor connection. This also allows the conductor track to be protected in the area of the opening for the motor connection.

[0054] It is also conceivable and feasible that the motor assembly has at least one electrical connection wire for electrically connecting the motor to the circuit board. Thus, except for the section provided for connection to the socket, the circuit board can be completely arranged in the interior space of the housing.

[0055] The opening in the housing required for connecting the wires can be smaller than the opening through which the circuit board extends for connecting to the motor, thereby improving the shielding of the interior space.

[0056] In the proposed embodiment of the motor assembly, the stator and the rotor may be arranged in a motor housing.

[0057] Exemplarily, the plug housing and the motor housing can be connected to each other. Exemplarily, the motor housing and the plug housing can be snap-fitted and / or adhesively bonded and / or screwed together. Furthermore, the motor housing and the plug housing can overlap. A combined plug-motor-housing design is particularly advantageous.

[0058] In the proposed embodiment of the motor assembly, the motor housing and / or the housing of the plug has a partition wall which separates the motor space from the interior space of the motor housing.

[0059] In principle, the motor can be connected to the motor shaft on the output side.

[0060] In the proposed design of the motor assembly, the housing of the plug can define a shaft space that is closed relative to the interior space of the housing and is used to accommodate a portion of the motor shaft, thereby improving the compact support of the motor shaft.

[0061] The shaft space can be designed to be essentially cylindrical. The motor shaft can be mounted in this shaft space. By mounting the motor shaft in a housing that is closed relative to the interior space, the printed circuit board can be protected from possible abrasive particles and / or lubricants of the mounting element.

[0062] In another embodiment of the proposed motor assembly, the shaft space can have an opening for the motor shaft on the side facing the motor. Thus, the motor shaft can extend from the motor space into the shaft space.

[0063] In another embodiment of the proposed motor assembly, the motor shaft can be configured with a main shaft on the side facing away from the plug for driving the adjustment mechanism. This facilitates the coupling of the motor assembly to the drive.

[0064] For example, a spindle drive that can be actuated by external forces can be implemented via a motor assembly. Such a spindle drive can be used, in particular, in an externally actuated adjustment mechanism for seat adjustment. For example, seat adjustment can involve height adjustment, longitudinal adjustment, backrest inclination adjustment, and / or headrest adjustment of a vehicle seat.

[0065] It is also conceivable and feasible to implement a window regulating mechanism for opening and closing the window that is actuated by external force.

[0066] In the proposed design of the motor assembly, the spindle can extend through an opening in the motor housing on the side facing away from the plug, which further simplifies the coupling of the motor assembly to the adjusting mechanism.

[0067] The motor assembly can be fastened to the vehicle seat to drive the adjustment mechanism of the vehicle seat. For example, the motor housing can have at least one fastening section on the side facing away from the plug for connecting the motor assembly to the vehicle seat. This simplifies the assembly effort for connecting the motor assembly to the adjustment mechanism of the vehicle seat.

[0068] The fastening sections can each be formed with an elongated hole. Thus, the motor assembly can be pre-assembled by loosely screwing on the screws, subsequently placed in the final assembly position by moving along the elongated holes, and then fixed by tightening the screws.

[0069] By way of example, the motor assembly can have exactly two fastening sections for this purpose.

[0070] The motor assembly may further include a plug that is detachably connectable to a portion of the circuit board configured to connect to the socket, thereby protecting the plug. For example, the plug may function as a socket dummy, i.e., configured like a socket for connection to the plug, but not suitable for supplying electrical energy.

[0071] Furthermore, the proposed motor assembly can also have a transport securing device connected to the housing, which externally covers the section of the printed circuit board provided for connection to the socket.

[0072] The transport restraint can be designed to be irreversibly detachable from the housing. Exemplarily, the connection between the transport restraint and the housing can be formed by a perforation or other material weakening. Furthermore, the transport restraint can be designed to be detached by initially connecting the plug to a socket provided for this purpose. Exemplarily, the transport restraint can be formed from a film.

[0073] In another embodiment of the proposed motor assembly, the transport lock is pivotably connected to the housing so as to be pivoted into an exposed position to expose the section of the printed circuit board provided for connection to the socket. This improves the protection of the plug even during further transport.

[0074] For example, the transport securing device can be connected to the housing via a film hinge, which can reduce manufacturing costs.

[0075] The advantages and designs of the specific embodiments related to the plug are also applicable to the motor assembly.

[0076] According to a further aspect of the proposed solution, the aforementioned object is also achieved by a vehicle seat having an adjustment mechanism and a motor assembly according to the proposed solution coupled to the adjustment mechanism. The adjustment mechanism allows adjustment of a vehicle seat installed in the vehicle as intended, and the adjustment mechanism can be actuated by a motor.

[0077] The advantages and designs of the specific embodiments related to the motor assembly are also applicable to the vehicle seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0092] Figure 1 A longitudinal section through an embodiment of the proposed plug 1 is shown. The plug 1 comprises a housing 3, which is configured with an opening 32 on the side shown on the right in the figure. A circuit board 2 is arranged in an interior space 31 defined by the housing 3, extending through the opening 32 of the housing 3 into the space enclosed by the housing 3. Conductor tracks 21 for conducting current run on the circuit board 2. In the section of the circuit board 2 arranged within the interior space 31 of the housing 3, the conductor tracks 21 extend on the outer surface of the circuit board 2 facing the interior space 31. In the region of the contact section 22 of the circuit board, which adjoins the opening 32 of the housing 3, the conductor tracks 21 extend within the circuit board 2. In the section of the circuit board 2 arranged outside the housing 3, the conductor tracks 21 extend on the outer surface of the circuit board 2 facing the surrounding space.

[0093] In order to facilitate the extension of the conductor tracks 21 within the circuit board 2, in an exemplary embodiment, the circuit board 2 can be composed of a plurality of layers 23. Figure 2 A circuit board 2 is shown consisting of two layers 23. To further classify, Figure 2 The layers 23 in the figures and all subsequent figures (as long as they involve multiple layers 23) are marked with a numerical subscript i. The first layer (i=1) and the second layer (i=2) each have a surface normal 25 perpendicular to the surface of the respective layer. In the circuit board 2 shown, the surface normals 25 of the two layers 23 extend parallel here. In addition, the two layers 23 are connected to each other and are arranged relative to each other so that the surface normals 25 extend parallel to the stacking direction 24, along which the layers 23 are joined and connected to each other. Each of the two layers 23 has an inner surface 26 that faces the other of the two layers 23. The remaining surfaces of the layers 23 together form the outer surface 27 of the circuit board 2. Figure 2 In the exemplary section of the double-layer circuit board 2 shown in FIG, the conductor tracks 21 extend in sections on the outer surface of the circuit board 2 and on the inner surface of the second layer. Figure 2 As shown above, conductor tracks 21 are arranged on the outer surface. Figure 2 In the section shown on the right, the conductor track 21 is located on the inner surface of the second layer. The sections of the conductor track 21 extending on the outer surface and the inner surface are electrically connected to each other via plated-through holes 213.

[0094] In an alternative embodiment, the multilayer printed circuit board 2 can also have more than Figure 2 The two layers shown in 23. To this end, Figure 3A section of a longitudinal section through a circuit board 2 with n layers is shown. Each of the n layers 23 has two surfaces in the stacking direction 24. Here, both surfaces of all layers 23 between the first layer and the nth layer are inner surfaces 26. The first layer and the nth layer each have an inner surface 26 and a surface facing away from the remaining layers 23. The surfaces facing away from the remaining layers 23 together form the outer surface 27 of the circuit board 2. The circuit board 2 has two conductor tracks 21. One of the conductor tracks 21 is arranged on the outer surface of the circuit board 2 at the first layer. The conductor tracks 21 mentioned extend from the outer surface via plated through-holes 213 to the inner surface of the second layer. In addition, Figure 3 The n-th layer circuit board 2 shown in FIG also includes a conductor track 21 arranged on the outer surface of the n-th layer. The conductor track 21 extends from the outer surface via the plated through hole 213 to the inner surface 26 of the n-th layer in the opposite direction of the stacking direction 24.

[0095] Figures 4A to 4D The perspective views of the embodiments of the proposed motor assembly are shown respectively. Figure 4A As can be seen in FIG, the motor assembly comprises a plug 1 having a housing 3 which encloses an interior space 31 apart from two openings 32 , 33 .

[0096] exist Figure 4A In the embodiment shown, the housing 3 is composed of two housing half shells 34 that can be assembled with each other. They can be arranged on each other and connected to each other in such a way that the interior space 31 is completely enclosed except for two openings 32 and 33. The housing 3 is designed to accommodate a circuit board 2, which is basically arranged in the interior space 31 of the housing 3. In order to connect the circuit board 2 to the socket 5 provided for it, the circuit board 2 can be arranged in the housing 3 so that a section of the circuit board 2 extends through the socket 5 provided for the circuit board 2. Figure 4A The opening 32 of the housing 3 is shown in the lower right of the middle. In order to electrically connect the socket 5 to the circuit board 2 (not shown), the socket is set up to be locked on the housing 3 using two locking sections 36. On the side of the housing 3 opposite to the opening 32 of the circuit board 2, the electric motor 4 of the motor assembly is connected to the housing 3. The motor 4 includes Figure 4A The rotor 42 and stator 41 are not shown in detail. The spindle 431 can be driven via the rotor 42. The motor 4 is essentially arranged in a motor space 443, which is surrounded by a motor housing 44. The motor housing 44 is connected to the housing 3 of the plug 1. The housing 3 has an opening 33 on the side facing the motor 4, through which the circuit board 2 can be electrically connected to the motor 4. Thus, when connected to the socket 5, the motor 4 can be supplied with electrical energy and / or electrical signals via the circuit board 2. Figure 4AThe motor assembly shown in FIG is configured to operate the adjustment mechanism by external force. In particular, the spindle drive can be operated via spindle 431. To secure the motor assembly to the adjustment mechanism, the motor housing 44 has two fastening sections 442 on the side facing away from the housing 3 of the plug 1. Each fastening section 442 has a hole for receiving a fastening element such as a screw or rivet.

[0097] and Figure 4A compared to, Figure 4B The motor assembly is shown in the assembled state. The circuit board 2 is thus inserted into the interior space 31 of the housing 3 of the plug 1 in such a way that the circuit board 2 protrudes through the opening 32. The two housing halves 34 are connected to each other. The housing 3 is thus assembled. Figure 4B In the ready-to-operate state of the motor assembly shown, the printed circuit board 2 can be supplied with electrical energy by connecting it to a correspondingly provided socket 5. Figure 4A It can also be seen that the socket 5 can be locked with the latching section 36 of the housing 3 of the plug 1 so as to be detachably but firmly connected to the housing 3. Here, the motor 4 for driving the spindle 431 can be supplied with electrical energy via the printed circuit board 2.

[0098] Figure 4C Also shown is a section of the socket 5 connected to the plug 1 in the state of being connected to the plug 1. For better understanding, the housing 3 and the electrical connection part of the socket 5 are not shown. Figure 4A and 4B As described above, the socket 5 is detachably connected to the housing plug in a position defined by the housing 3. Here, the socket 5 is connected to the conductor track 21 extending in the outer section of the circuit board 2 to transmit electrical energy and / or electrical signals to the circuit board 2.

[0099] Figure 4D Shown with Figures 4A to 4C This figure shows the section of the plug 1 that is set up to be connected to the socket 5. Figure 4A and Figure 4C In contrast, the conductor track 21 is shown on an outer section of the circuit board 2 that projects through the opening 32 and is set up for connection to the socket 5. The conductor track 21 is arranged centrally on the outer section. Figure 4D The section shown in FIG is configured with plated through-holes 213. Here, the conductor tracks 21 extend within the circuit board 2 within the contact section 22 between the circuit board 2 and the housing 3. In the outer section of the circuit board 2, the conductor tracks 21 extend via the plated through-holes 213 to the outer surface 27 of the circuit board 2, so that electrical energy and / or electrical signals can be transmitted to the conductor tracks 21 at this location.

[0100] In designs of the outer surface of the circuit board 2 that differ from the embodiment shown, multiple conductor tracks 21 can also be arranged on the outer surface. This allows, in particular, electrical energy and / or electrical signal energy to be transmitted into multiple conductor tracks 21. This can increase redundancy or reduce heating of the conductor tracks 21. Furthermore, the design of at least one conductor track 21 on the outer surface can differ from the design shown here with plated through-holes 213.
