Description

TECHNICAL FIELD

[0001] The invention relates to a plug connector part for connecting with a counterpart plug connector part, a connection device having such a plug connector part, and a method for manufacturing a connection device. BACKGROUND

[0002] Plug connector parts which guide not only data conductors but also load conductors are sometimes also referred to as hybrid plug connector parts. Such plug connector parts enable a single-cable solution and thereby make devices compact by integrating the functions of contacts for power transmission, signal transmission and data transmission for electrical / optical within the plug connection device.

[0003] In an exemplary embodiment of a circular plug connector part, the hybrid device plug connector part has a housing thread connection for connecting with a corresponding counterpart plug connector part. In actual embodiments, the housing thread connection can be made of an electrically conductive material and thus represents an external EMV shield. The abbreviation "EMV" here as usual stands for "Electro Magnetic Compatibility" and denotes the ability of a technical device not to disturb other devices or to be disturbed by other devices due to undesired electrical or electromagnetic effects.

[0004] The external EMV shield thus protects the plug connector part from external electromagnetic coupling or electromagnetic radiation, and vice versa protects external systems from interference from the plug connector part. Since sensitive data signals are often transmitted within hybrid plug connector parts, an additional "internal" EMV shield is often provided. The internal EMV shield protects the individual data conductors from electromagnetic interference from the load conductors (which can also be referred to as power contacts) within the plug connector part. The internal EMV shield and the external EMV shield can be electrically connected to one another or, alternatively, electrically isolated from one another.

[0005] For example, the standards IEC 63171-7 ("SPE M12 hybrid connector") and IEC 61076-2-117 ("M12-M40 hybrid connector") describe hybrid plug connector parts.

[0006] In general, there is an increasing interest in hybrid interfaces. Here, the challenge is that the number of different variants of plug connector parts is increasing and thus makes manufacturing relatively costly. SUMMARY

[0007] It is the task of the invention to simplify the manufacture of plug connector parts.

[0008] This task is solved by the subject matter having the features of claim 1.

[0009] Thus, the plug connector part, which is intended for connection to a mating plug connector part which it fits, comprises a plurality of data conductors, an inner shield which externally surrounds the data conductors, a plurality of conductors which are arranged externally to the inner shield, and an outer shield which externally surrounds the data conductors, the inner shield and the conductors. In this arrangement, the inner shield and the outer shield each have a connection contact section for electrical contact with a respective mating contact, wherein the inner shield and the outer shield are electrically isolated from one another and can be electrically connected to one another by means of the connection contact sections.

[0010] This is based on the recognition that some users of such plug connector parts take the electrical connection of the outer shield to the inner shield as a given, while other users wish to keep the two shields galvanically isolated from one another. Since, in the respective standards (IEC 63171-6, IEC 63171-7, IEC 61076-2-113 and IEC 61076-2-117), it is not specified whether the inner shield and the outer shield should be electrically connected to one another or galvanically isolated from one another. This leaves it to the manufacturer of the plug connector part to provide the hybrid plug connector part either with the shields isolated or connected, or to set up different product varieties. The proposed plug connector part solves this problem in that the user can himself decide on the electrical connection of the two shields, namely in that the user electrically connects or does not electrically connect the connection contact sections of the two shields to one another. The connection contact elements can be connected, for example, to corresponding contacts of a circuit board, for example by means of THR, SMD or wave soldering methods or crimping technology. With the design of the circuit board layout, the user can define the wiring of the circuit board contacts and thus the shielding scheme of the hybrid plug connector part. The inner shield and the outer shield are in particular EMV shields as described at the outset.

[0011] In this way, a variable shielding scheme can be provided for a hybrid plug connector part, in particular a device plug connector part, which enables the electrical connection or electrical isolation of the electrical potentials of the inner shield and the outer shield to be implemented according to the design. This scheme thus enables a reduction in product varieties. A reduction in product varieties firstly enables cost and time advantages in the development process for the manufacturer of the plug connector part. Furthermore, the effort in the procurement, assembly, quality assurance, warehousing and imaging processes of the products can be reduced in the EDV (IT) system. At the same time, the flexibility of the variable solution increases the convenience for the user. Furthermore, the risk of confusing products with connected shielding potentials with products with isolated shielding potentials can be reduced.

[0012] The plug connector part is constructed, for example, according to the standards IEC 63171-6, IEC 63171-7, IEC 61076-2-113 or IEC 61076-2-117. The conductors arranged outside the inner shield are, in particular, electrical conductors, for example signal conductors and / or power conductors, in particular load conductors for conducting a load current.

[0013] The inner shield can be electrically insulated from the outer shield inside the outer shield by an outer insulator. This achieves a reliable insulation and at the same time a stable retention.

[0014] The connection contact section of the inner shield and / or the connection contact section of the outer shield is constructed, for example, in the form of a pin, respectively. This enables a particularly simple electrical contacting, for example on a circuit board.

[0015] The connection contact section of the inner shield and the connection contact section of the outer shield can be oriented parallel to one another. Both connection contact sections can thus be electrically connected to a circuit board in a simple manner, for example in one step.

[0016] The connection contact section of the inner shield and / or the connection contact section of the outer shield and / or the connection contact section of the data conductor and / or the connection contact section of the (outer) conductor can be inserted into a hole of a circuit board. The plug connector part can thus be simply mounted on a circuit board in one step.

[0017] The outer shield can be constructed with a housing screw connection. The outer shield can have at least one thread. This enables a reliable fixing on a housing and / or a reliable fixing with a mating plug connector part.

[0018] The connection contact section of the outer shield can be constructed on a contact spring. The contact spring is optionally spring- elastically pre-tensioned relative to a base body of the outer shield. This enables a simple manufacture of the base body while at the same time a reliable electrical contacting with the connection contact section.

[0019] According to one aspect, a connection arrangement is provided, comprising a plug connector part according to any of the design solutions described herein, and a circuit board. With regard to advantages, reference is made to the above explanations for the embodiments of the plug connector part.

[0020] The mating contact for the connection contact section of the inner shield and the mating contact for the connection contact section of the outer shield can be electrically isolated from one another. The inner shield is thus galvanically isolated from the outer shield, and the plug connector part is suitable for applications in which such an isolation is intended.

[0021] The counter contact of the connection contact section for the inner shield and the counter contact of the connection contact section for the outer shield can be electrically connected or electrically connected with mutually different ground potentials or reference potentials. An effective EMV shielding can thus be ensured.

[0022] Alternatively, the counter contact of the connection contact section for the inner shield and the counter contact of the connection contact section for the outer shield can be electrically connected to one another. The plug connector part is then suitable for applications in which the two potentials are intended to be electrically connected.

[0023] Optionally, the counter contact of the connection contact section for the inner shield and the counter contact of the connection contact section for the outer shield are electrically connected to one another by means of at least one electrical or electronic structural element and / or are in operative connection. In this way, completely new application possibilities are provided, for example monitoring of the shields and / or selective electrical connection of the two shields.

[0024] The at least one structural element can comprise a resistor, an inductor, a capacitor, a diode and / or a varistor. Optionally, a network of the structural elements mentioned and / or others is provided. This allows a complex analysis of the shield potentials and also enables targeted influencing of the properties of the shielding system.

[0025] The counter contact of the connection contact section for the inner shield and the counter contact of the connection contact section for the outer shield can be constructed on mutually different circuit board layers of a circuit board. In this way, the shield potentials can be guided separately from one another.

[0026] According to one aspect, a method for manufacturing a connection device, in particular according to any of the design solutions described herein, is proposed. The method comprises the steps of manufacturing or selecting a circuit board having counter contacts, and electrically contacting the connection contact sections of the plug connector part according to any of the design solutions described herein with the counter contacts of the circuit board. It is provided here that the circuit board is manufactured or selected in such a way that the counter contact of the connection contact section for the inner shield and the counter contact of the connection contact section for the outer shield are selectively electrically isolated from one another or electrically connected to one another. With regard to the advantages, reference is made to the above explanations relating to the embodiments of the plug connector part. BRIEF DESCRIPTION OF DRAWINGS

[0036] Reference is made at the same time to Figures 1 to 5 which shows a plug-in connector part 1 for connection with a mating plug-in connector part 2. At present, the plug-in connector part 1 is configured, for example, as a circular plug-in connector part, more particularly as a hybrid device plug-in connector part. Furthermore, an exemplary circuit board 30 is shown, which together with the plug-in connector part 1 forms a connection device 3. In the assembled state, the plug-in connector part 1 lies against the circuit board 30 and is electrically connected therewith.

[0037] The plug-in connector part 1 comprises a plurality, here two, (electrical) data lines 10 and an inner shield 12 which surrounds the data lines 10. The data lines 10 can also be referred to as data contacts. The inner shield 12 has a base body 123 in which the data lines 10 are arranged. The base body 123 is configured in the form of a sleeve. The inner shield 12 is made of an electrically conductive material, here of metal, for example of aluminum or brass. The inner shield 12 provides an EMV shielding for the data lines 10. The inner shield 12 is configured in the form of a shield plate.

[0038] ​​​​Furthermore, the plug connector part 1 comprises conductors, which are here exemplarily shown as load conductors 11, arranged outside the inner shield 12 (wherein, alternatively or additionally, the conductors 11 can also comprise other data conductors, signal conductors or generally power conductors), and also an outer shield 13. In the example shown, the load conductors 11 have a larger cross section than the data conductors 10. The load conductors 11 serve for the transmission of a load current, for example for powering a device having the plug connector part 1 or for being powered by a device having the plug connector part 1. The outer shield 13 encloses the data conductors 10, the inner shield 12 and the load conductors 11. The outer shield 13 has an inner space in which the inner shield 12 together with the data conductors 10 arranged therein and the load conductors 11 next to the inner shield are arranged. The outer shield 13 provides an EMV shielding for the data conductors 10 and the load conductors 11.

[0039] The outer shield 13 is made of an electrically conductive material, here of metal, for example of aluminum or brass. The outer shield 13 has a thread 131 for the nut 16. Here, the outer shield 13 constitutes a housing thread connection. By means of the nut 16 screwed onto the thread 131, the plug connector part 1 can be screwed with a wall in an opening of the wall. The outer shield 13 also has a base body 133 on which, next to the thread 131 for the nut 16, a thread 134 is configured, which serves for a mating thread of a mating plug connector part 2, which is adapted to the thread. Thus, the base body 133 serves both as an outer EMV shield and for a housing thread connection and also for screwing with the mating plug connector part 2.

[0040] Furthermore, contacts for functional earthing "FE", shielding contacts and additional signal contacts for the protection of earthing "PE" can also be integrated.

[0041] Furthermore, the plug connector part 1 comprises an inner insulation 14. As especially according to Figure 5As can be seen, the data conductors 10 are held by the inner insulation 14. The inner insulation 14 surrounds the data conductors 10. Here, the plug-in contact ends of the data conductors 10 protrude on one side from the inner insulation 14 for plug-in connection with corresponding counter plug-in contacts of the counter plug-in connector part 2. On the opposite side of the inner insulation 14, the connection contact sections 100 of the data conductors 10 protrude from the inner insulation 14. The connection contact sections 100 of the data conductors 10 are intended for insertion into the holes 303 of the circuit board 30. Furthermore, the inner insulation 14 has a locking element 140 by means of which the inner insulation 14 is latched in the assembled state with a corresponding locking element 152 of the outer insulation 15. The form-fit connection ensures the position. To this end, the inner insulation 14 has in particular at least one locking hook which is latched in the assembled state in an undercut of the outer insulation 15. The inner insulation 14 electrically insulates the data conductors 10 from the inner shield 12.

[0042] The plug-in connector part 1 also comprises an outer insulation 15. The outer insulation 15 carries the load conductors 11 and the inner shield 12 (together with the inner insulation 14 and the data conductors 10). Here, the outer insulation 15 has a cylindrical section 151 in which and along which the load conductors 11 and the inner shield 12 (together with the inner insulation 14 and the data conductors 10) extend. In the example shown, the outer insulation 15 and the base body 133 do not latch into one another. The parts are not fixed to one another by the plug-in connector structure. The outer insulation 15 is fixedly connected with the circuit board 30 by means of the connection contact sections 100. The circuit board 30 is fixed in the device, for example, by means of screws or clips. This ensures that the outer insulation 15 is also positioned relative to the base body 133 which is likewise fixed on the device. There is thus no force expenditure which could bend the circuit board when assembling, and the housing can be opened simply without the latches being released. The outer insulation 15 has a foot 150 with which the plug-in connector 1 is in abutment in the assembled state with the circuit board. A positioning pin 153 is configured for insertion into a hole 303 in the circuit board 30 in order thus to ensure correct positioning. By means of the outer insulation 15, the inner shield 12 is electrically insulated from the outer shield 13 on the inside of the outer shield 13. The plug-in contact ends of the load conductors 11 are accessible on one side in the outer insulation 15 for plug-in connection with corresponding counter plug-in contacts of the counter plug-in connector 2. On the opposite side of the outer insulation 15, the connection contact sections 110 of the load conductors 11 protrude from the outer insulation 15. The connection contact sections 110 of the load conductors 11 are intended for insertion into corresponding holes 303 of the circuit board 30.

[0043] The data conductor 10, the inner insulation 14 and the inner shield 12 form a preassembled preassembly. This preassembly is pushed into the outer insulation 15 with the load conductor 11 during assembly.

[0044] The plug connector part 1 is optionally constructed according to any one of the standards IEC 63171-6, IEC 63171-7, IEC 61076-2-113 or IEC 61076-2-117.

[0045] The inner shield 12 and the outer shield 13 have a connection contact section 120, 130, respectively, for electrical contact with a corresponding mating contact 300A, 300B, which will be explained in detail below. The inner shield 12 and the outer shield 13 are electrically isolated from each other. The inner shield 12 and the outer shield 13 can be electrically connected to each other by the connection contact sections 120, 130. The connection contact sections 120, 130 are spaced apart from each other.

[0046] In the example shown, the connection contact section 120 of the inner shield 12 is constructed by a shield conductor 121, which extends in a receptacle 122 of the inner shield 12. The shield conductor 121 can be electrically contacted by a shield conductor of a mating plug connector 2.

[0047] The connection contact section 130 of the outer shield 13 is constructed on a contact spring 132. The contact spring 132 is spring- elastically pre-tensioned relative to a base body 133 of the outer shield 13. The contact spring 132 has a plurality of spring arms 136. The contact spring 132 is pre-tensioned relative to the base body 133 of the outer shield 13. Here, the contact spring 132 is currently supported on a shoulder 154 of the outer insulation 15. In the example shown, the shoulder 154 adjoins an end of a cylindrical section 151 of the outer insulation 15.

[0048] The contact spring 132 is pushed laterally onto the outer insulation 15. Furthermore, the contact spring 132 has an opening 137. In the assembled state, the opening 137 is plugged onto a positioning pin 155 of the outer insulation 15. The positioning pin 155 is oriented perpendicular to a direction in which the spring arms 136 are pushed against the base body 133 of the outer shield 13.

[0049] The connection contact section 120 of the inner shield 12 and the connection contact section 130 of the outer shield 13 are each constructed in the form of a pin. The connection contact section 120 of the inner shield 12 and the connection contact section 130 of the outer shield 13 are oriented parallel to each other. The connection contact section 120 of the inner shield 12 and the connection contact section 130 of the outer shield 13 can be respectively inserted into a hole 303 of a circuit board 30.

[0050] Therefore, the potential electrical connection between the inner shield 12 and the outer shield 13 is not realized inside the plug connector part 1, but outside the plug connector part 1 and onto the circuit board layout of the respective application. For this purpose, the inner shield 12 and the outer shield 13 are galvanically isolated from each other as described. Both shield potentials are separately, respectively, led out of the plug connector part 1 with at least one connection contact section 120, 130. The plug connector part 1 can also be referred to as a circuit board plug connector part. By means of the respective wiring of the circuit board contacts, the user defines whether the inner shield 12 and the outer shield 13 are electrically connected or not.

[0051] Reference is made to Figures 6A to 12C , where exemplary manufacturing steps of the connection device 3 are described in the following. Here, side views (e.g. Fig. 1 Figure 6A and Figure 7A ) are shown above, top views (e.g. Fig. 1 Figure 7B and Figure 8B ) are shown in the middle, where the inner shield 12 and the outer shield 13 in the connection device are electrically insulated from each other, and top views (e.g. Fig. 1 Figure 7C and Figure 8C ) are shown below, where the inner shield 12 and the outer shield 13 in the connection device are electrically connected to each other.

[0052] First, the circuit board layout is developed for the application, typically with circuit board design software. Here, the details of the circuit board are defined and, by this, also the wiring of the circuit board contacts. Therefore, this step decides whether the inner shield 12 and the outer shield 13 are connected or not. In particular, the circuit board design file is delivered to the circuit board manufacturer in a common format (e.g. in Gerber files or Zuken-Archiv files). Then, the circuit board material is selected. Here, for example, an insulating circuit board substrate (e.g. FR4) is used, on which a conductive coating (e.g. a copper film) has been applied (on one or both sides). This is shown in Fig. 1 Figures 6A-6C .

[0053] In a next step, the manufacture of the conductive pattern is carried out. By means of an ablative process (for example, etching, milling or laser), the conductor and pad geometry is revealed from the electrically conductive coating. Here, the mating contacts 300A, 300B, 300C are produced, which serve for the connection of the data conductor, the load conductor, the inner shield 12 and the outer shield 13 connection contact sections 100, 110, 120, 130. Furthermore, if an electrical connection conductor 301 is required between the mating contacts 300A, 300B of the inner shield 12 and the outer shield 13 in the design file, this electrical connection conductor is also produced here. From a cost perspective, the connections thus made are zero-cost, since no additional expenditure is incurred for the ablation of the connections on the circuit board 30 or for the non-ablation of the connections. In circuit boards with electrically conductive inner layers, these work steps are carried out for each inner layer. The individual circuit board planes are then stacked and pressed into a circuit board. In Figures 7A-7C The circuit board 30 after the completion of the manufacture of the conductive pattern is shown in

[0054] In a next step, drilling and optionally plating is carried out. Here, the holes 303 are produced, for example, for the connection contact sections 100, 110, 120, 130 and the positioning pins 153 of the plug connector part 1. The electrically conductive connections between the conductors in the different circuit board planes, so-called vias, are produced in an optional downstream plating or chemical deposition process. Subsequently, a solder resist film and / or printing is optionally applied. Further process steps for the manufacture of the circuit board contour can then be carried out. Here, material removal methods such as milling, sawing or scraping are usually involved. In Figures 8A-8C The circuit board 30 after the completion of the manufacture of the holes is shown in

[0055] In a next step, the configuration of the circuit board is carried out. The plug connector part 1 is configured manually or automatically, optionally as shown, with the exception of the housing screw connection consisting of the base body 133 of the outer shield 13 and the nut 16. For automatic configuration, a suction hood can be provided on the plug connector part 1 in order to position the product with a vacuum gripper. The connection between the connection contact sections 120, 130 of the inner shield 12 and the outer shield 13 of the plug connector part 1 and the mating contacts 300A, 300B can be achieved with a crimping technique. In this case, the circuit board 30 is then completed. If the connection is to be established by means of an SMD or THR reflow soldering method, for example, solder paste is applied to the circuit board joints before the configuration of the circuit board. Figures 9A-9C The circuit board 30 is shown, which is configured with the part of the plug connector part 1.

[0056] In a further step, the connection contact sections 100, 110, 120, 130 of the plug-in connector part 1 are soldered, for example by means of SMD, THR, wave soldering or hand soldering methods. After this work step (or in the crimping technique after the aforementioned steps), the connection contact sections 120, 130 of the inner shield 12 and the outer shield 13 are materially (in the crimping technique: force) connected to the counter contacts 300A, 300B of the circuit board 30. Figures 10A-10C The plug-in connector part 1 (in the example shown, apart from the housing screw connection consisting of the base body 133 of the outer shield 13 and the nut 16) is shown soldered on the soldering site 304. The contact spring 132 of the outer shield 13 is already fitted on the outer insulation 15 here.

[0057] Then (or already at an earlier point in time), the base body 133 of the outer shield 13 is fitted into the panel or switch cabinet wall or other housing wall 4 and is screwed fast thereon by means of the nut 16, see Figure 11A and Figure 11B .

[0058] Finally, the configured and soldered circuit board 30 is installed into the device, see Figures 12A-12C In this step, the inner components of the hybrid plug-in connector part 1 are joined with the housing screw connection. The contact spring electrically connects the housing screw connection with the corresponding connection contact section 130. Depending on the design of the circuit board layout, there is an electrical connection of the inner shield 12 and the outer shield 13 at this point, or the shield potential is isolated or otherwise bridged (see below).

[0059] According to Figure 12B , the counter contact 300A for the connection contact section 120 of the inner shield 12 and the counter contact 300B for the connection contact section 130 of the outer shield 13 are electrically isolated from one another.

[0060] According to Figure 12C , the counter contact 300A for the connection contact section 120 of the inner shield 12 and the counter contact 300B for the connection contact section 130 of the outer shield 13 are electrically connected to one another by means of the connection conductor 301 of the circuit board 30.

[0061] Generally, the following steps can be provided in a method for manufacturing the connection arrangement 3: (a) manufacturing or selecting a circuit board 30 having mating contacts 300A-300C, and (b) electrically contacting the connection contact sections 100, 110, 120, 130 of the plug connector part 1 with the mating contacts 300A-300C of the circuit board 30, wherein the circuit board 30 is manufactured or selected such that the mating contact 300A for the connection contact section 120 of the inner shield 12 and the mating contact 300B for the connection contact section 130 of the outer shield 13 are selectively electrically isolated from each other or electrically connected to each other.

[0062] Different possibilities can be considered for the specific design of the circuit board 30, wherein several examples are described in the following.

[0063] In an alternative according to Figure 12B , the connection contact sections 120, 130 of the inner shield 12 and the outer shield 13 of the plug connector part 1 are only connected with the circuit board joint for mechanical reasons and are electrically insulated from each other. Figure 19B The respective circuit diagram is shown.

[0064] In an alternative according to Figure 13A and Figure 13B , the circuit board 30 has an upper side with an electrically conductive circuit board layer 302A Figure 13A and a lower side with an electrically conductive circuit board layer 302B Figure 13B . The mating contacts 300A, 300B of the inner shield 12 and the outer shield 13 (in the form of circuit board joints) are electrically connected to different outer circuit board layers 302A, 302B. In the shown example, the central circuit board joint, i.e. the mating contact 300A of the inner shield 12, is electrically connected on the lower side with the electrically conductive outer circuit board layer 302B (so-called bottom layer) of the circuit board 30 by means of a contact 305. By means of an insulation 306, the mating contact 300B of the outer shield 13 is electrically insulated from said circuit board layer 302B. The circuit board joint with the mating contact 300B of the outer shield 13 is electrically connected with another outer circuit board layer 302A (top layer) by means of a contact 305. By means of an insulation 306, the mating contact 300A of the inner shield 12 is electrically insulated from said circuit board layer 302A. Here, the top layer and the bottom layer are embodied to be galvanically isolated from each other. Thus, for example, different ground potentials or reference potentials can be realized for the inner shield 12 and the outer shield 13.

[0065] Figure 14 The respective circuit diagram is shown according to Figure 19AFig. 2 shows another example of the electrically conductive connection of the mating contacts 300A, 300B of the inner shield 12 and the outer shield 13. Here, the mating contacts 300A, 300B are electrically connected to the same ground potential or reference potential. To this end, the two mating contacts 300A, 300B are connected by a contact 305 into the same electrically conductive circuit board layer. From this it follows that the inner shield 12 and the outer shield 13 are electrically connected to the same ground potential or reference potential. Figure 13A , 13B and Figure 15 Alternative embodiments result from the fact that the ground potentials or reference potentials inside the circuit board 30 are electrically connected to each other.

[0066] According to Figure 15 , the connection contact sections 120, 130 of the inner shield 12 and the outer shield 13 are connected to different inner circuit board layers 302C, 302D. In the example shown, the mating contact 300A of the central inner shield 12 is connected to an electrically conductive first inner circuit board layer 302D, and the mating contact 300B of the outer shield 13 is connected to an electrically conductive second inner circuit board layer 302C. These circuit board layers 302C, 302D are galvanically isolated from each other. According to Figure 13A and Figure 13B and according to Figure 15 the embodiments can be combined arbitrarily. Thus, for example, another embodiment can be realized by connecting the inner shield 12 and the outer shield 13 to an outer circuit board layer and to an inner circuit board layer.

[0067] According to Figure 16 , the mating contacts 300A, 300B are connected by connection wires 308A, 308B, respectively, to different regions 309 and thus to a ground potential or reference potential on the same circuit board layer.

[0068] According to Figure 17 , the mating contacts 300A, 300B are connected by connection wires 308A, 308B, respectively, to different ground contacts or reference contacts, which are, for example, directed to other circuit board planes or other system components.

[0069] According to Figure 18The counter contacts 300A for the connection contact section 120 of the inner shield 12 and the counter contacts 300B for the connection contact section 130 of the outer shield 13 are electrically connected to one another by the electric or electronic structural element(s) 31. It is provided here that at least one electric or electronic structural element 31 is used between the shield potentials. For this purpose, an interrupted connection site is provided in the connection line 301 between the counter contacts 300A, 300B of the inner shield 12 and the outer shield 13. The interruption is configured with at least one or a plurality of structural elements 31 (connected in series and / or in parallel using SMD and / or THR). Alternatively, the connection can also be realized between the counter contacts 300A, 300B and a ground plane or reference plane of the circuit board. This arrangement allows, for example, defined resistances, inductances or capacitances and networks of these structural elements to be installed. When the inner shield is terminated to the outer shield or to a ground plane with the common-mode impedance of the data line(s) 10, this arrangement can be used, for example, to optimize the asymmetrical attenuation. Furthermore, the data line 10 can be terminated to the inner shield 12 and / or to the outer shield 13 with its differential-mode impedance in order to, for example, terminate the transmission line. This application case is of particular interest for multipoint applications.

[0070] Furthermore, low-pass, band-pass or high-pass filters and resonant circuits can be provided between the shield potentials. They can couple or isolate the shield potentials from one another in certain operating states. Further implementation methods are obtained by using one or more diodes or one or more varistors, which only allow a coupling in one direction or in the event of a fault. In this view, interference can be conducted from the inner shield 12 to the outer shield 13, but no external interference reaches the inner shield 12 of the data line 10.

[0071] If desired, the connection site can be configured with measuring technology or optical or acoustic components. These structural elements can be used purposefully for fault indication in order to warn of a dangerous state or to switch off the supply in a hybrid connection. One or more fuses or one or more switches can be provided as structural elements. In this case, the combination of the hybrid plug connector part 1 and the connection of the terminal on a fault current-protecting switch as a structural element can be of particular interest in order to switch off the device in the event of a dangerous current on the accessible shield potential. The use of switches can be used purposefully to interrupt the potential in certain operating situations, for example, device start-up, motor start-up, welding process, etc.

[0072] Figure 19C and Figure 19DPossible circuit diagrams using one or more of the structural elements 31 are shown. At least one structural element 31 can be connected between the inner shield 12 and the outer shield 13, or the inner shield 12 and the outer shield 13 can be connected to other components via at least one structural element 31, respectively.

[0073] The idea on which the application is based is not restricted to the foregoing embodiments, but can in principle be implemented in different types of ways.
