Description

[0001] Connector part with electrically connectable shields

[0002] The invention relates to a connector part for connection to a mating connector part, a connection arrangement with such a connector part and a method for producing a connection arrangement.

[0003] Connector components that carry both data lines and power lines are sometimes referred to as hybrid connector components. Such connector components enable single-cable solutions and thus compact devices by functionally integrating contacts for electrical / optical power, signal, and data transmission within a single connector.

[0004] In an exemplary embodiment of a circular connector part, a hybrid device connector part has a housing screw connection for connecting to a corresponding mating connector part. In practical designs, the housing screw connection can be made of a conductive material and thus represent an external EMC shield. The abbreviation EMC stands, as usual, for "electromagnetic compatibility" and describes the ability of a technical device not to interfere with other devices through unwanted electrical or electromagnetic effects, or conversely, not to be interfered with by other devices.

[0005] The outer EMC shielding thus protects the connector part from external electromagnetic interference or radiation, and conversely, external systems from interference from the connector part. Since sensitive data signals are typically transmitted within a hybrid connector part, additional "inner" EMC shielding is usually provided. The inner EMC shielding protects the respective data lines from electromagnetic interference from the load lines within the connector part, which can also be referred to as power contacts. The inner EMC shielding and the outer EMC shielding can be electrically connected to each other or, alternatively, galvanically isolated from each other.

[0006] For example, the standards IEC 63171-7 ("SPE M12 Hybrid") and IEC 61076-2-117 ("M12-M40 Hybrid") describe hybrid connector components. There is generally growing interest in hybrid interfaces. One challenge is the increasing number of different variants of connector components, which makes manufacturing relatively complex.

[0007] The object of the present invention is to simplify the production of connector parts.

[0008] This object is achieved by an article having the features of claim 1.

[0009] Accordingly, a connector part for connection to a matching mating connector part comprises a plurality of data lines, an inner shield surrounding the data lines on the outside, a plurality of lines arranged outside the inner shield, and an outer shield surrounding the data lines, the inner shield, and the lines on the outside. It is provided that the inner shield and the outer shield each have a connection contact section for electrically contacting a respective mating contact, wherein the inner shield and the outer shield are electrically separated from one another and electrically connectable to one another via the connection contact sections.

[0010] This is based on the realization that some users of such connector components require an electrical connection between the outer and inner shielding, while others prefer to keep the two shields galvanically isolated. The corresponding standards (IEC 63171-6, IEC 63171-7, IEC 61076-2-113, and IEC 61076-2-117) do not specify whether the inner and outer shields should be electrically connected or galvanically isolated. This presents connector component manufacturers with the decision of whether to offer a hybrid connector component with separate or connected shields, or to provide different product variants.The proposed connector component solves this problem by allowing the user to decide on the electrical connection of the two shields, namely by electrically connecting the connection contact sections of the two shields or not. The connection contact elements can be connected to corresponding terminals on a printed circuit board, e.g., using THR, SMD, or wave soldering processes or press-fit technology. By designing the printed circuit board layout, the user can define the interconnection of the printed circuit board terminals and thus the shielding concept of the hybrid connector component. The inner shielding and the outer shielding each represent, in particular, EMC shielding, as described above.

[0011] In this way, a variable shielding concept can be created for hybrid connector components, particularly device connector components, which, depending on the configuration, enables either an electrical connection or galvanic isolation of the potentials of the inner and outer shielding. This concept thus enables reduced product variance. Reduced product variance initially provides the connector component manufacturer with cost and time advantages in the development process. Furthermore, costs in procurement, assembly, quality assurance, warehousing, and the representation of the products in IT systems can be reduced. At the same time, the benefits for users increase due to the flexibility of a variable solution. Furthermore, the risk of confusing products with connected shielding potentials and those with separate shielding potentials can be reduced.

[0012] The connector part is constructed, for example, according to the standard IEC 63171-6, IEC 63171-7, IEC 61076-2-113, or IEC 61076-2-117. The cables arranged outside the inner shielding are, in particular, electrical cables, e.g., signal cables and / or power cables, especially load cables for carrying a load current.

[0013] The inner shielding can be electrically insulated from the outer shielding by an external insulating body. This enables reliable insulation and, at the same time, a stable mounting.

[0014] The connection contact section of the inner shield and / or the connection contact section of the outer shield is / are (each) designed in the form of a pin. This enables particularly simple electrical contact, 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 aligned parallel to each other. This allows the two connection contact sections to be easily electrically connected, for example, to a printed circuit board 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 sections of the data lines and / or the connection contact sections of the (outer) lines can be plugged into holes in a printed circuit board. This allows the connector part to be easily plugged onto a printed circuit board in one step.

[0017] The outer shielding can form a housing screw connection. The outer shielding can have at least one thread. This enables secure attachment to a housing and / or to a mating connector part.

[0018] The connection contact section of the outer shield can be formed on a contact spring. The contact spring is optionally spring-loaded against a base body of the outer shield. This enables simple production of the base body while simultaneously ensuring secure electrical contact with the connection contact section.

[0019] According to one aspect, a terminal assembly is provided, comprising the connector part according to any embodiment described herein and a printed circuit board. Regarding the advantages, reference is made to the above statements regarding the 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 separated from each other. This galvanically isolates the inner shield from the outer shield, making the connector suitable for applications where such isolation is required.

[0021] 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 connected or connected to different ground or reference potentials. This ensures effective EMC shielding.

[0022] Alternatively, 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 connected to one another. The connector part is then suitable for applications in which an electrical connection between the two potentials is specified. Optionally, 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 are electrically connected and / or operatively connected to one another via at least one electrical or electronic component. This opens up entirely new application possibilities, such as monitoring the shields and / or selective electrical connection between the two shields.

[0023] The at least one component can comprise a resistor, an inductor, a capacitor, a diode, and / or a varistor. Optionally, a network of such and / or other components is provided. This allows for a complex analysis of the shielding potentials and also enables targeted manipulation of the properties of the shielding system.

[0024] 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 located on different PCB layers. This allows the shield potentials to be routed separately from each other.

[0025] According to one aspect, a method for producing a connection arrangement, in particular according to any embodiment described herein, is specified. The method comprises the following steps: producing or selecting a printed circuit board with mating contacts, and electrically contacting the connection contact sections of a connector part according to any embodiment described herein with the mating contacts of the printed circuit board. Provision is made here for the printed circuit board to be produced or selected such that the mating contacts for the connection contact section of the inner shield and for the connection contact section of the outer shield are or will be selectively electrically separated from one another or electrically connected to one another. With regard to the advantages, reference is made to the above statements regarding the connector part.

[0026] The concept underlying the invention will be explained in more detail below with reference to the exemplary embodiments illustrated in the figures. They show:

[0035] Fig. 13A to 18 different designs of the circuit board; and

[0036] Fig. 19A to 19D Circuit diagrams for different designs of the circuit board.

[0037] Figs. 1 to 5, which are referred to jointly, show a connector part 1 for connection to a mating connector part 2. In the present case, the connector part 1 is designed, for example, as a circular connector part, specifically as a hybrid device connector part. Furthermore, an exemplary printed circuit board 30 is shown, which, together with the connector part 1, forms a connection arrangement 3. In the assembled state, the connector part 1 rests against the printed circuit board 30 and is electrically connected thereto.

[0038] The connector part 1 comprises several, here two, (electrical) data lines 10 and an inner shield 12 surrounding 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 sleeve-shaped. The inner shield 12 is made of an electrically conductive material, in this case a metal such as aluminum or brass. The inner shield 12 provides EMC shielding for the data lines 10. The inner shield 12 is in the form of a shielding plate.Furthermore, the connector part 1 comprises lines arranged outside the inner shielding 12, which are shown here by way of example as load lines 11 (wherein the lines 11 can alternatively or additionally also comprise further data lines, signal lines or general power lines), and an outer shielding 13. In the example shown, the load lines 11 have a larger cross-section than the data lines 10. The load lines 11 are used to transmit load currents, e.g. to supply power to a device with the connector part 1 or to supply power to a device with the connector part 1. The outer shielding 13 surrounds the data lines 10, the inner shielding 12 and the load lines 11. The outer shielding 13 has an interior space in which the inner shielding 12 with the data lines 10 arranged therein and, next to it, the load lines 11 are arranged.The outer shield 13 provides EMC shielding for the data lines 10 and the load lines 11.

[0039] The outer shield 13 is made of an electrically conductive material, in this case a metal such as aluminum or brass. The outer shield 13 has a thread 131 for a nut 16. In this case, the outer shield 13 forms a housing screw connection. By means of the nut 16 screwed onto the thread 131, the connector part 1 can be screwed to the wall in an opening in a wall. The outer shield 13 further has a base body 133, on which (next to the thread 131 for the nut 16) a thread 134 is formed for a matching counter-thread of the mating connector part 2. The base body 133 thus serves both as external EMC shielding and as a housing screw connection and for screwing to the mating connector part 2.

[0040] Furthermore, contacts for a protective earth “PE”, a functional earth “FE”, shield contacts and additional signal contacts can be integrated.

[0041] Furthermore, the connector part 1 comprises an inner insulating body 14. As can be seen in particular from Fig. 5, the data lines 10 are held by the inner insulating body 14. The inner insulating body 14 encloses the data lines 10. On one side, plug contact ends of the data lines 10 protrude from the inner insulating body 14 for plugging into corresponding mating plug contacts of the mating connector 2. On the opposite side of the inner insulating body 14, connection contact sections 100 of the data lines 10 protrude from the inner insulating body 14. The connection contact sections 100 of the data lines 10 are used for insertion into holes 303 in the printed circuit board 30. Furthermore, the inner insulating body 14 has locking elements 140, by means of which the inner insulating body 14, in the assembled state, is locked to corresponding locking elements 152 of an outer insulating body 15. A positive connection secures the position.For this purpose, the inner insulating body 14 specifically has at least one locking hook, which locks into an undercut of the outer insulating body 15 during assembly. The inner insulating body 14 electrically insulates the data lines 10 from the inner shielding 12.

[0042] The connector part 1 further comprises the outer insulating body 15. The outer insulating body 15 carries the load lines 11 and the inner shielding 12 including the inner insulating body 14 and data lines 10. The outer insulating body 15 has a cylindrical section 151 in and along which the load lines 11 and the inner shielding 12 including the inner insulating body 14 and data lines 10 run. In the example shown, the outer insulating body 15 and the base body 133 do not snap together. These parts are not fastened to one another by the connector construction. The outer insulating body 15 is firmly connected to the printed circuit board 30 via the connection contact sections 100. The printed circuit board 30 is fastened in a device, e.g., by screws or clamps. This secures the position of the outer insulating body 15 relative to the base body 133, which is also fastened to the device.This eliminates the need for force during assembly that could cause the circuit board to bend, and allows the housing to be opened easily without releasing any locking mechanisms. The outer insulating body 15 has feet 150 with which the connector 1 rests against the circuit board when assembled. Positioning pins 153 are designed to be inserted into holes 303 in the circuit board 30 to ensure correct positioning. The outer insulating body 15 electrically insulates the inner shielding 12 inside the outer shielding 13 from that of the outer shielding 13. On one side, plug contact ends of the load lines 11 are accessible for plugging into corresponding mating contacts of the mating connector 2 in the outer insulating body 15. On the opposite side of the outer insulating body 15, connection contact sections 110 of the load lines 11 protrude from the outer insulating body 15.The connection contact sections 110 of the load lines 11 are used for insertion into corresponding holes 303 of the circuit board 30.

[0043] The data lines 10, the inner insulating body 14, and the inner shielding 12 form a pre-assembled subassembly. The subassembly is inserted into the outer insulating body 15 with the load lines 11 during assembly. The connector part 1 is optionally designed according to one of the standards IEC 63171-6, IEC 63171-7, IEC 61076-2-113, or IEC 61076-2-117.

[0044] The inner shield 12 and the outer shield 13 each have a connection contact section 120, 130 for electrically contacting a respective mating contact 300A, 300B, which will be explained in more detail below. The inner shield 12 and the outer shield 13 are electrically separated from one another. The inner shield 12 and the outer shield 13 are electrically connectable to one another via the connection contact sections 120, 130. The connection contact sections 120, 130 are spaced apart from one another.

[0045] In the example shown, the connection contact section 120 of the inner shield 12 is formed by a shield cable 121, which runs in a receptacle 122 of the inner shield 12. The shield cable 121 can be electrically contacted by a shield cable of the mating connector 2.

[0046] The connection contact section 130 of the outer shield 13 is formed on a contact spring 132. The contact spring 132 is resiliently preloaded against the base body 133 of the outer shield 13. The contact spring 132 has a plurality of spring arms 136. The contact spring 132 is preloaded against the base body 133 of the outer shield 13. In this case, the contact spring 132 is supported on a shoulder 154 of the outer insulating body 15. In the example shown, the shoulder 154 borders one end of the cylindrical section 151 of the outer insulating body 15.

[0047] The contact spring 132 is pushed laterally onto the outer insulating body 15. The contact spring 132 also has an opening 137. In the assembled state, the opening 137 is plugged onto a positioning pin 155 of the outer insulating body 15. The positioning pin 155 is oriented perpendicular to the direction in which the spring arms 136 press against the base body 133 of the outer insulating body 13.

[0048] The connection contact section 120 of the inner shield 12 and the connection contact section 130 of the outer shield 13 are each designed 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 aligned parallel to one another. The connection contact section 120 of the inner shield 12 and the connection contact section 130 of the outer shield 13 can each be inserted into a hole 303 of the printed circuit board 30. Thus, a potential electrical connection point between the inner and outer shields 12, 13 is not realized within the connector part 1, but outside the connector part 1 and transferred to the printed circuit board layout of the respective application. For this purpose, the inner and outer shields 12, 13 are galvanically isolated from one another as described.Both shield potentials are separate, each with at least one connection contact section 120, 130.

[0049] Connector part 1 is brought out. Connector part 1 can also be referred to as a printed circuit board connector part. By wiring the printed circuit board connections, the user defines whether the inner shielding 12, 13 is electrically connected or not.

[0050] With reference to Figs. 6A to 12C, steps of an exemplary manufacture of the connection arrangement 3 will now be described below. In each case, a side view is shown at the top (e.g., Figs. 6A and 7A), a top view in the middle in a case in which the inner and outer shields 12, 13 in the connection arrangement are electrically insulated from one another (e.g., Figs. 7B and 8B), and a top view in a case in which the inner and outer shields 12, 13 in the connection arrangement are electrically connected to one another (e.g., Figs. 7C and 8C) is shown below.

[0051] First, a circuit board layout is developed for an application, usually using circuit board design software. This defines the details of the circuit board and thus also the wiring of the circuit board connections. This step determines whether the inner and outer shields 12, 13 are connected. A circuit board design file is submitted to a circuit board manufacturer, preferably in a common format (e.g., as a Gerber file or as a Zuken archive). A circuit board material is then selected. This could be, for example, an insulating circuit board base material (e.g., FR4) to which conductive coatings (e.g., copper foils) have already been applied (on one or both sides). This is shown in Fig. 6A-6C.

[0052] The next step involves creating the conductive pattern. Using an ablation process (e.g., etching, milling, or lasering), conductor and pad geometries are exposed from the conductive coating. This creates the mating contacts 300A, 300B, 300C for the connection contact sections 100, 110, 120, 130 of the data lines, the load lines, the inner shield 12, and the outer shield 13. Furthermore, an electrical connecting line 301 is created between the mating contacts 300A, 300B of the inner and outer shields 12, 13, if required in the design file. From a cost perspective, the connection produced in this way is neutral because the removal or non-removal of the connection on the circuit board 30 does not result in any additional expenditure. For circuit boards with conductive inner layers, these work steps are performed for each inner layer.The individual circuit board layers are then stacked and pressed together to form a single circuit board. Figures 7A-7C show the circuit board 30 after the circuit pattern has been created.

[0053] In the next step, drilling and optionally electroplating are performed. This creates holes 303, e.g., for the connection contact sections 100, 110, 120, 130 and positioning pins 153 of the connector part 1. Conductive connections between conductors in different circuit board levels, so-called through-holes, are created in an optional downstream electroplating or chemical deposition process. Solder mask and / or printing are then optionally applied. Further process steps may follow to produce the circuit board contours. These typically involve separating processes such as milling, sawing, or scribing. Figs. 8A-8C show the circuit board 30 after the holes have been created.

[0054] In a subsequent step, the printed circuit board is populated. The connector part 1 (optionally as shown except for the housing screw connection consisting of the base body 133 of the outer shield 13 and the nut 16) is populated manually or automatically. For automatic assembly, a suction cap can be provided on the connector part 1 to position the product with a vacuum gripper. The connection between the connection contact sections 120, 130 of the inner and outer shield 12, 13 of the connector part 1 and the mating contacts 300A, 300B can be realized using a press-fit technology; in this case, the printed circuit board 30 is then fully populated. If the connection is to be made using SMD or THR reflow soldering processes, a solder paste is applied to the printed circuit board connections, for example, before the circuit board is populated. Fig. 9A-9C show the printed circuit board 30 equipped with the mentioned parts of the connector part 1.

[0055] In a further step, the connection contact sections 100, 110, 120, 130 of the connector part 1 are soldered, e.g., using SMD, THR, wave, or hand soldering processes. After this step (or after the previous step in the case of press-fit technology), the connection contact sections 120, 130 of the inner and outer shielding 12, 13 are firmly connected (positively connected in the case of press-fit technology) to the mating contacts 300A, 300B of the printed circuit board 30. Figs. 10A-10C show the connector part 1 soldered at soldering points 304 (in the example shown, except for the housing screw connection consisting of the base body 133 of the outer shielding 13 and the nut 16). The contact spring 132 of the outer shielding 13 is already mounted on the outer insulating body 15.

[0056] Then (or at an earlier point in time), the base body 133 of the outer shielding 13 is mounted in a panel or a control cabinet wall or another housing wall 4 and screwed thereto by means of the nut 16, see Fig. 11A and 11B.

[0057] Finally, the populated and soldered circuit board 30 is installed in a device, see Figs. 12A-12C. In this step, the internal components of the hybrid connector part 1 are joined to the housing screw connection. The contact spring electrically connects the housing screw connection to the corresponding terminal contact section 130. Depending on the configuration of the circuit board layout, an electrical connection now exists between the inner and outer shields 12, 13, or the shield potentials are separate or interconnected differently (see below).

[0058] According to Fig. 12B, the mating contact 300A for the terminal contact section 120 of the inner shield 12 and the mating contact 300B for the terminal contact section 130 of the outer shield 13 are electrically separated from each other.

[0059] According to Fig. 12C, the mating contact 300A for the terminal contact section 120 of the inner shield 12 and the mating contact 300B for the terminal contact section 130 of the outer shield 13 are electrically connected to each other via the connecting line 301 of the printed circuit board 30.

[0060] In general, the following steps can be provided in a method for manufacturing the connection arrangement 3: (a) manufacturing or selecting the printed circuit board 30 with mating contacts 300A-300C and (b) electrically contacting the connection contact sections 100, 110, 120, 130 of the connector part 1 with the mating contacts 300A-300C of the printed circuit board 30, wherein the printed circuit board 30 is manufactured or selected such that the mating contacts 300A, 300B for the

[0061] Connection contact section 120 of the inner shield 12 and for the

[0062] The connection contact section 130 of the outer shield 13 is either electrically separated from one another or electrically connected to one another. Various options are conceivable for the specific design of the printed circuit board 30, several examples of which are described below.

[0063] In the alternative shown in Fig. 12B, the terminal contact sections 120, 130 of the inner and outer shields 12, 13 of the connector part 1 are connected to the circuit board terminals only for mechanical reasons and are electrically insulated from each other. Fig. 19B shows a corresponding circuit diagram.

[0064] In the alternative according to Figs. 13A and 13B, the circuit board 30 has a top side with a conductive circuit board layer 302A (Fig. 13A) and a bottom side with a conductive circuit board layer 302B (Fig. 13B). The mating contacts 300A, 300B (in the form of circuit board terminals) of the inner and outer shielding 12, 13 are electrically connected to the different outer circuit board layers 302A, 302B. In the example shown, the central circuit board terminal, the mating contact 300A of the inner shielding 12, is electrically connected on the bottom side to the so-called bottom layer as an outer conductive circuit board layer 302B of the circuit board 30 by means of a contact 305. The mating contact 300B of the outer shielding 13 is electrically insulated from this circuit board layer 302B by an insulation 306.The circuit board connection with the mating contact 300A of the outer shield 13 is electrically connected to the top layer as another outer circuit board layer 302A by means of a contact 305. The mating contact 300A of the inner shield 12 is electrically insulated from this circuit board layer 302A by an insulation 306. The top and bottom layers are galvanically isolated from each other. This allows, for example, different ground or reference potentials to be implemented for the inner and outer shields 12, 13.

[0065] Fig. 14 shows another example with electrically connected mating contacts 300A, 300B of the inner and outer shields 12, 13 according to the circuit diagram of Fig. 19A. Here, the mating contacts 300A, 300B are electrically connected to the same ground or reference potential. For this purpose, both mating contacts 300A, 300B are connected via contacts 305 in the same electrically conductive circuit board layer. An alternative embodiment is shown in Figs. 13A, 13B, and 15, where the ground or reference potentials within the circuit board 30 are electrically connected to one another.

[0066] According to Fig. 15, the connection contact sections 120, 130 of the inner and outer shields 12, 13 are connected to different inner circuit board layers 302C, 302D. In the example shown, the central mating contact 300A of the inner shield 12 is connected to a first inner conductive circuit board layer 302D, and the mating contact 300B of the outer shield 13 is connected to a second inner conductive circuit board layer 302C. The circuit board layers 302C, 302D are galvanically isolated from one another. The embodiments according to Figs. 13A and 13B and according to Fig. 15 can be combined as desired. For example, another embodiment could be achieved by connecting the inner and outer shields 12, 13 in an outer and an inner circuit board layer.

[0067] According to Fig. 16, the mating contacts 300A, 300B are each connected via a connecting line 308A, 308B to different fields 309 and thus to ground or reference potentials on the same circuit board layer.

[0068] According to Fig. 17, the mating contacts 300A, 300B are each connected via a connecting line 308A, 308B to different ground or reference terminals, which lead, for example, to other circuit board levels or other system components.

[0069] According to Fig. 18, 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 electrically connected to one another via (at least) one electrical or electronic component 31. The use of at least one electrical or electronic component 31 between the shield potentials is provided. For this purpose, an interrupted connection point is provided in a connecting line 301 between the mating contacts 300A, 300B of the inner and outer shields 12, 13. The interruption is equipped with at least one or more (series and / or parallel connection, SMD and / or THR) component(s) 31. Alternatively, the connection can also be realized between the mating contacts 300A, 300B and the ground or reference planes of a printed circuit board. This arrangement allows, for example,the installation of defined resistors, inductors, or capacitances, as well as networks of these components. Such an arrangement can be used, for example, to optimize asymmetry attenuation if the inner shielding is terminated with the common-mode impedance of the data line(s) 10 against the outer shielding or a ground plane. Furthermore, the data lines 10 can be terminated with their differential-mode impedance against the inner and / or outer shielding 12, 13, for example, to terminate a transmission line. This application is particularly interesting for multidrop applications. Furthermore, low-pass, band-pass, or high-pass filters, as well as resonant circuits, can be provided between the shield potentials. These can couple or separate the shield potentials under certain operating conditions.Further embodiments result from the use of one or more diodes or one or more varistors, which allow coupling only in one direction or in the event of a fault. From this perspective, interference could be diverted from the inner shield 12 to the outer shield 13, but no external interference could reach the inner shield 12 of the data lines 10.

[0070] If necessary, the connection point can be equipped with measuring technology or optical or acoustic components. These components can be used specifically for fault indication, to warn of dangerous conditions or to switch off the power supply in the hybrid connection. One or more fuses or one or more switches can be provided as component(s). In this context, the combination of a hybrid connector part 1 and the connection to a residual current device (as a component) could be particularly interesting for switching off a system in the event of dangerous currents on the accessible shield potentials. The use of switches can be specifically used to interrupt the potentials in certain operating situations (e.g., system startup, motor start-up, welding processes, etc.).

[0071] Figs. 19C and 19D show possible circuit diagrams for the use of one or more of the described components 31. The at least one component 31 can be connected between the inner and outer shielding 12, 13 or the inner and outer shielding 12, 13 can each be connected to further components via at least one component 31.

[0072] The concept underlying the invention is not limited to the embodiments described above, but can in principle also be implemented in a completely different manner.
