Description
Steckverbinderteil mit einer Widerstandkodierung Connector part with a resistance coding
Beschreibung Die Erfindung betrifft ein Steckverbinderteil zum Übertragen eines Ladestroms nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zum Herstellen eines Steckverbinderteils. The invention relates to a connector part for transmitting a charging current according to the preamble of claim 1 and to a method for producing a connector part.
Ein solches Steckverbinderteil umfasst mindestens zwei Kontaktelemente zum Herstellen eines elektrischen Kontakts mit zugeordneten Kontaktelementen eines anderen Steckverbinderteils. Die mindestens zwei Kontaktelemente sind an einem Trägerelement des Steckverbinderteils angeordnet und werden über das Trägerelement in Position gehalten. Steckverbinderteile der hier beschriebenen Art dienen zum Übertragen eines Ladestroms insbesondere zum Aufladen eines Elektrofahrzeugs. Üblicherweise wird hierbei ein Elektrofahrzeug über eine Ladestation geladen, wobei das Elektrofahrzeug beispielsweise ein Steckverbinderteil in Form einer Ladebuchse aufweist, die über ein geeignetes Ladekabel an die Ladestation angeschlossen werden kann. Such a connector part comprises at least two contact elements for producing an electrical contact with associated contact elements of another connector part. The at least two contact elements are arranged on a carrier element of the connector part and are held in position via the carrier element. Connector parts of the type described here are used to transmit a charging current, in particular for charging an electric vehicle. Typically, in this case an electric vehicle is charged via a charging station, wherein the electric vehicle, for example, has a connector part in the form of a charging socket, which can be connected via a suitable charging cable to the charging station.
Ein Elektrofahrzeug kann grundsätzlich auf unterschiedliche Weise geladen werden. Entsprechend sind zur Verbindung eines Elektrofahrzeugs mit einer Ladestation auch unterschiedliche Verbindungseinrichtungen bekannt, die unterschiedliche Steckverbinderteile aufweisen können. Beispielsweise kann eine Verbindungseinrichtung zum Übertragen eines Wechselstroms ausgelegt sein, um dem Elektrofahrzeug einen Ladestrom in Form eines Wechselstroms zuzuführen. Beim Anschließen eines Elektrofahrzeugs an eine Steckdose wird beispielsweise ein einphasiger Wechselstrom übertragen. Über eine Ladestation kann jedoch auch ein dreiphasiger Wechselstrom eingespeist werden. Alternativ kann das Aufladen auch mittels eines Gleichstroms erfolgen. Abhängig von der Stromart und Stromstärke sind daher die Steckverbinderteile zum Anschließen des Elektrofahrzeugs an eine Ladestation oder eine Steckdose ausgelegt. An electric vehicle can basically be charged in different ways. Accordingly, different connection devices are known for connecting an electric vehicle with a charging station, which may have different connector parts. For example, a connection device for transmitting an alternating current may be designed to supply a charging current in the form of an alternating current to the electric vehicle. When connecting an electric vehicle to a socket, for example, a single-phase alternating current is transmitted. However, a charging station can also supply a three-phase alternating current. Alternatively, the charging can also be done by means of a direct current. Depending on the type of current and current, therefore, the connector parts for connecting the electric vehicle to a charging station or a socket are designed.
Um sicherzustellen, dass bei Verbindung eines Elektrofahrzeugs mit einer Ladestation über ein Ladekabel ein in das Elektrofahrzeug eingespeister Ladestrom eine zulässige Maximalstromstärke, für die das Ladekabel und ein Ladesystem des Elektrofahrzeugs ausgelegt sind, nicht überschritten wird, wird an Steckverbinderteilen eine
Widerstandskodierung verwendet, wie dies beispielsweise in der DE 10 2010 053 074 A1 und der DE 20 2012 100 613 U1 beschrieben und zudem in einschlägigen Normen, beispielsweise der IEC 62196, normiert ist. Beispielsweise kann in einem Stecker eines Ladekabels zwischen einem so genannten Näherungskontakt und einem Schutzleiterkontakt ein Widerstand geschaltet sein, dessen Widerstandswert bei Anschließen des Steckers an eine Ladestation über die Ladestation gemessen werden kann, um anhand des Widerstandswerts den Typ des angeschlossenen Ladekabels zu erkennen. Unterschiedlichen Widerstandswerten sind hierbei bestimmte Typen von Ladekabeln oder Ladeeinrichtungen zugeordnet, so dass anhand des Widerstandswerts dieser Typ identifiziert werden kann. Insbesondere kann auf diese Weise eine zulässige Maximalstromstärke, die beispielsweise über ein Ladekabel übertragen werden kann (beispielsweise 16 A oder 32 A) identifiziert werden, so dass entsprechend die Ladestation einen eingespeisten Strom begrenzen kann. Zu ähnlichem Zweck dient eine Widerstandskodierung beispielsweise an einem Steckverbinderteil in Form einer Ladebuchse an einem Elektrofahrzeug. In diesem Fall kann anhand eines Widerstandswerts insbesondere ein maximal zulässiger Ladestrom, für den das Ladesystem des Elektrofahrzeugs ausgelegt ist, identifiziert werden. Herkömmlich ist das Anordnen eines solchen Widerstands zum Zwecke der Widerstandskodierung an einem Steckverbinderteil vergleichsweise aufwendig und erfordert beispielsweise ein Verbinden eines Widerstands mit zugeordneten Kontaktelementen durch Krimpen oder dergleichen. Aus der EP 1 094 566 B1 ist ein Steckverbinder bekannt, bei dem zwischen zwei Kontaktstiften ein Metallblech mit einem daran angeordneten Widerstandschip angeordnet und zwischen die Kontaktstifte geschaltet ist. To ensure that when connecting an electric vehicle with a charging station via a charging cable a charging current fed into the electric vehicle, a maximum permissible current for which the charging cable and a charging system of the electric vehicle are designed, is not exceeded in connector parts Resistance coding used, as described for example in DE 10 2010 053 074 A1 and DE 20 2012 100 613 U1 and also standardized in relevant standards, such as the IEC 62196. For example, in a plug of a charging cable, a resistor may be connected between a so-called proximity contact and a protective conductor contact, the resistance of which can be measured when the plug is connected to a charging station via the charging station in order to recognize the type of connected charging cable based on the resistance value. Different resistance values are associated with certain types of charging cables or charging devices, so that this type can be identified on the basis of the resistance value. In particular, in this way an allowable maximum current that can be transmitted, for example, via a charging cable (for example, 16 A or 32 A) can be identified, so that correspondingly the charging station can limit an applied current. For similar purpose, a resistor coding is used for example on a connector part in the form of a charging socket on an electric vehicle. In this case, a maximum permissible charging current, for which the charging system of the electric vehicle is designed, can be identified on the basis of a resistance value. Conventionally, the placement of such a resistor for the purpose of resistance coding on a connector part is comparatively expensive and requires, for example, a connection of a resistor with associated contact elements by crimping or the like. From EP 1 094 566 B1, a connector is known in which a metal sheet with a resistor chip arranged thereon is arranged between two contact pins and connected between the contact pins.
Bei einem aus der DE 10 2009 023 292 A1 bekannten elektrischen Verbinder ist eine Kontaktbrücke vorgesehen, die zwei Kontaktstifte kurzschließt. In an electrical connector known from DE 10 2009 023 292 A1, a contact bridge is provided which short-circuits two contact pins.
Aufgabe der vorliegenden Erfindung ist es, ein Steckverbinderteil und ein Verfahren zum Herstellen eines Steckverbinderteils zur Verfügung zu stellen, dem auf einfache Weise die Integration einer Widerstandseinrichtung in ein Steckverbinderteil zum Zwecke einer Widerstandskodierung ermöglichen.
Diese Aufgabe wird durch einen Gegenstand mit den Merkmalen des Anspruchs 1 gelöst. Object of the present invention is to provide a connector part and a method for producing a connector part available, which allow in a simple way the integration of a resistance device in a connector part for the purpose of a resistance coding. This object is achieved by an article having the features of claim 1.
Demnach weist die Widerstandseinrichtung eine Leiterplatte, einen an der Leiterplatte angeordneten elektrischen Widerstand und mindestens eine an der Leiterplatte angeordnete, mit dem Widerstand elektrisch verbundene Kontaktfeder auf, wobei die Leiterplatte an dem Trägerelement gehalten ist und die mindestens eine Kontaktfeder eins der mindestens zwei Kontaktelemente elektrisch kontaktiert. Die vorliegende Erfindung geht von dem Gedanken aus, eine Widerstandseinrichtung modular unter Verwendung einer Leiterplatte und eines daran angeordneten Widerstands auszubilden. Die Widerstandseinrichtung kann in einfacher Weise an dem Trägerelement des Steckverbinderteils angeordnet werden und wird in einem Montagezustand fest an dem Trägerelement gehalten. Dadurch, dass ein Kontakt zwischen dem Widerstand und einem zugeordneten Kontaktelement über eine an der Leiterplatte angeordnete Kontaktfeder ausgebildet wird, kann der elektrische Kontakt des Widerstands mit dem zugeordneten Kontaktelement in einfacher, leicht zu montierender Weise hergestellt werden, indem die Kontaktfeder und das zugeordnete Kontaktelement kontaktierend miteinander in Anlage gebracht werden. Insbesondere entfällt hierdurch das Erfordernis für eine in der Montage aufwendige Verbindung des Widerstands mit einem zugeordneten Kontaktelement beispielsweise durch Krimpen, so dass sich die Montage des Steckverbinderteils insgesamt vereinfacht. Accordingly, the resistance device has a printed circuit board, an electrical resistor arranged on the printed circuit board and at least one contact spring electrically connected to the resistor, the printed circuit board being held on the carrier element and the at least one contact spring electrically contacting one of the at least two contact elements , The present invention is based on the idea of forming a resistance device in a modular manner using a printed circuit board and a resistor arranged thereon. The resistance device can be arranged in a simple manner on the carrier element of the connector part and is held firmly in an assembled state on the carrier element. Characterized in that a contact between the resistor and an associated contact element is formed via a arranged on the circuit board contact spring, the electrical contact of the resistor with the associated contact element can be made in a simple, easy to install manner by contacting the contact spring and the associated contact element be brought into contact with each other. In particular, this eliminates the need for a complicated in the assembly connection of the resistor with an associated contact element, for example, by crimping, so that simplifies the installation of the connector part as a whole.
Vorzugsweise sind an der Leiterplatte zwei Kontaktfedern angeordnet, von denen eine erste Kontaktfeder ein erstes der mindestens zwei Kontaktelemente und eine zweite Kontaktfeder ein zweites der mindestens zwei Kontaktelemente elektrisch kontaktiert. Über die zwei Kontaktfedern ist der Widerstand somit elektrisch mit den zugeordneten Kontaktelementen verbunden, so dass der Widerstand elektrisch zwischen die Kontaktelemente geschaltet ist. Die Kontaktfedern sind zumindest abschnittsweise elastisch ausgebildet und können federnd mit den zugeordneten Kontaktelementen in Anlage gebracht werden, so dass, bei Anlage der Kontaktfedern an den zugeordneten Kontaktelementen, die Kontaktfedern unter Vorspannung sind und somit ein zuverlässiger, niederohmiger Kontakt zwischen den Kontaktfedern und den zugeordneten Kontaktelementen hergestellt wird. Preferably, two contact springs are arranged on the printed circuit board, of which a first contact spring electrically contacts a first of the at least two contact elements and a second contact spring electrically contacts a second of the at least two contact elements. Via the two contact springs, the resistor is thus electrically connected to the associated contact elements, so that the resistor is electrically connected between the contact elements. The contact springs are elastically formed at least in sections and can be resiliently brought into abutment with the associated contact elements, so that, upon contact of the contact springs on the associated contact elements, the contact springs are biased and thus a reliable, low-resistance contact between the contact springs and the associated contact elements will be produced.
Vorzugsweise sind die Kontaktfedern an unterschiedlichen Seiten der Leiterplatte angeordnet. So weist die Leiterplatte eine erste Seite und eine der ersten Seite
abgewandte, zweite Seite auf. Die erste Kontaktfeder kann hierbei an der ersten Seite und die zweite Kontaktfeder an der abgewandten, zweiten Seite angeordnet sein, so dass die Kontaktfedern zu unterschiedlichen Seiten von der Leiterplatte vorstehen. An einer der Seiten, beispielsweise der ersten Seite, ist hierbei auch der Widerstand angeordnet. An der Leiterplatte erstrecken sich geeignete Leiterbahnen, die die Kontaktfedern mit dem Widerstand elektrisch kontaktieren. Preferably, the contact springs are arranged on different sides of the circuit board. Thus, the circuit board has a first side and a first side opposite, second side on. The first contact spring may in this case be arranged on the first side and the second contact spring on the remote, second side, so that the contact springs protrude to different sides of the circuit board. On one of the sides, for example the first side, in this case, the resistor is arranged. On the circuit board suitable tracks extend, which electrically contact the contact springs with the resistor.
Möglich ist aber auch, dass die Kontaktfedern an der gleichen Seite der Leiterplatte angeordnet sind. It is also possible that the contact springs are arranged on the same side of the circuit board.
Die Leiterplatte (engl. „Printed Circuit Board") verwirklicht wie üblich einen Träger für elektrische Bauelemente und besteht beispielsweise aus einem elektrisch isolierenden Grundkörper, auf dem Leiterbahnen angeordnet sind. Zur Herstellung des elektrischen Kontakts zwischen der Kontaktfeder und dem zugeordneten Kontaktelement weist die Kontaktfeder vorzugsweise eine Kontaktfläche auf, die in dem Montagezustand des Steckverbinderteils mit einem zylindrischen Kontaktabschnitt des zugeordneten Kontaktelements kontaktierend in Anlage ist. Die Kontaktfläche der Kontaktfeder ist von der Seite der Leiterplatte, an der die Kontaktfeder angeordnet ist, entfernt und liegt somit von der Seite ab. Über einen Federarm ist die Kontaktfläche an die zugeordnete Seite der Leiterplatte angebunden und somit federnd an der Leiterplatte gehalten. As usual, the printed circuit board realizes a carrier for electrical components and consists, for example, of an electrically insulating basic body on which printed conductors are arranged a contact surface which is in contact with a cylindrical contact portion of the associated contact element in the assembled state of the connector part, the contact surface of the contact spring being away from the side of the circuit board on which the contact spring is located, and thus being away from the side a spring arm, the contact surface is connected to the associated side of the circuit board and thus resiliently held on the circuit board.
Der Kontaktabschnitt muss nicht notwendigerweise zylindrisch, insbesondere kreiszylindrisch geformt sein, sondern kann auch eine andere Form, beispielsweise einen rechteckigen oder auf andere Weise mehreckigen Querschnitt aufweisen. The contact portion does not necessarily have to be cylindrical, in particular circular-cylindrical, but may also have another shape, for example a rectangular or otherwise polygonal cross-section.
Die Leiterplatte ist in einer vorteilhaften Ausgestaltung formschlüssig an einer Halteeinrichtung des Trägerelements gehalten. Die Leiterplatte kann hierbei beispielsweise in die Halteeinrichtung eingesteckt sein, so dass die Halteeinrichtung die Leiterplatte zumindest abschnittsweise umgreift und die Leiterplatte somit steckend an dem Trägerelement befestigt ist. Es ergibt sich ein einfacher Montageprozess, bei dem die Widerstandseinrichtung mit ihrer Leiterplatte in einfacher Weise durch Einstecken in die Halteeinrichtung an dem Trägerelement festgelegt werden kann. The circuit board is held in an advantageous embodiment form-fitting manner to a holding device of the carrier element. In this case, the printed circuit board can be plugged into the holding device, for example, so that the holding device engages around the printed circuit board at least in sections and the printed circuit board is thus fastened to the carrier element in a plug-in manner. This results in a simple assembly process, in which the resistance device can be fixed with its printed circuit board in a simple manner by insertion into the holding device on the support element.
Der Widerstand und/oder die mindestens eine Kontaktfeder der Widerstandseinrichtung können vorteilhafterweise als SMD-Bauteile ausgebildet und mittels Lötens an der
Leiterplatte befestigt sein. SMD-Bauteile haben, im Gegensatz zu Bauelementen zur Durchsteckmontage, keine Drahtanschlüsse, sondern werden mittels lötfähiger Anschlussflächen direkt auf eine Leiterplatte gelötet. Die Befestigung solcher Bauteile an der Leiterplatte erfolgt somit in Oberflächenmontage, ohne dass Anschlussdrähte durch Bestückungslöcher der Leiterplatte hindurchgeführt werden müssen. The resistor and / or the at least one contact spring of the resistance device can advantageously be designed as SMD components and soldered to the PCB attached. SMD components, in contrast to through-hole components, have no wire connections, but are soldered directly onto a circuit board using solderable pads. The attachment of such components to the circuit board is thus carried out in surface mounting, without connecting wires must be passed through mounting holes of the circuit board.
Grundsätzlich können die Bauteile aber auch mittels Durchsteckmontage an der Leiterplatte angeordnet sein. Der Widerstand der Widerstandseinrichtung dient insbesondere zur Widerstandskodierung. Entsprechend weist der Widerstand vorzugsweise einen Widerstandswert auf, der einer vorbestimmten Kenninformation zugeordnet ist, so dass anhand des Widerstandswerts die Kenninformation über ein mit dem Steckverbinderteil verbundenes, anderes Steckverbinderteil identifiziert werden kann. Verwirklicht das Steckverbinderteil beispielsweise einen Ladestecker eines Ladekabels, so kann bei Anschließen des Ladesteckers beispielsweise an eine Ladestation über eine geeignete Messeinrichtung der Ladestation der Widerstandswert des Widerstands der Widerstandseinrichtung in dem Ladestecker des Ladekabels gemessen werden. Anhand des gemessenen Widerstandswerts, der beispielsweise in normierter Weise einer vorbestimmten Kenninformation zugeordnet ist, kann diese Kenninformation dann identifiziert werden. Die Kenninformation kann beispielsweise einen maximal zulässigen Ladestrom (beispielsweise 16 A oder 32 A), eine Typinformation eines Ladekabels oder einer Ladeeinrichtung eines Elektrofahrzeugs oder auch andere Informationen über ein Steckverbinderteil oder ein Ladesystem angeben. In principle, however, the components can also be arranged by means of push-through mounting on the printed circuit board. The resistance of the resistance device is used in particular for resistance coding. Accordingly, the resistor preferably has a resistance value which is assigned to a predetermined characteristic information, so that the identification information can be identified by means of the resistance value via a different connector part connected to the connector part. Realizes the connector part, for example, a charging connector of a charging cable, it can be measured when connecting the charging plug, for example, to a charging station via a suitable measuring device of the charging station, the resistance of the resistor device in the charging connector of the charging cable. On the basis of the measured resistance value, which is assigned, for example, in a standardized manner to a predetermined characteristic information, this identification information can then be identified. The identification information can specify, for example, a maximum permissible charging current (for example 16 A or 32 A), type information of a charging cable or a charging device of an electric vehicle or other information about a connector part or a charging system.
Die Aufgabe wird auch gelöst durch ein Verfahren zum Herstellen eines Steckverbinderteils zum Übertragen eines Ladestroms, wobei das SteckverbinderteilThe object is also achieved by a method for producing a connector part for transmitting a charging current, wherein the connector part
- mindestens zwei Kontaktelemente zum Herstellen eines elektrischen Kontakts mit zugeordneten Kontaktelementen eines anderen Steckverbinderteils, at least two contact elements for establishing an electrical contact with associated contact elements of another connector part,
- ein Trägerelement, an dem die mindestens zwei Kontaktelemente angeordnet werden, und a carrier element on which the at least two contact elements are arranged, and
- eine Widerstandseinrichtung, die elektrisch mit den mindestens zwei Kontaktelementen verbunden wird, a resistance device, which is electrically connected to the at least two contact elements,
aufweist. Dabei ist vorgesehen, dass die Widerstandseinrichtung eine Leiterplatte, einen an der Leiterplatte angeordneten elektrischen Widerstand und mindestens eine an der Leiterplatte angeordnete, mit dem Widerstand elektrisch verbundene Kontaktfeder aufweist, wobei die Leiterplatte an dem Trägerelement angeordnet und sodann das
mindestens eine Kontaktelement an das Trägerelement angesetzt wird derart, dass die mindestens eine Kontaktfeder eins der mindestens zwei Kontaktelemente elektrisch kontaktiert. Zu Vorteilen und vorteilhaften Ausgestaltungen des Verfahrens soll auf das vorangehend Ausgeführte verwiesen werden, das analog auch auf das Verfahren Anwendung findet. having. It is provided that the resistance device has a printed circuit board, an arranged on the circuit board electrical resistance and at least one arranged on the circuit board, electrically connected to the resistor contact spring, wherein the circuit board is arranged on the support member and then the at least one contact element is attached to the carrier element such that the at least one contact spring electrically contacts one of the at least two contact elements. For advantages and advantageous embodiments of the method, reference should be made to the above, which also applies analogously to the method.
Der der Erfindung zugrunde liegende Gedanke soll nachfolgend anhand der Figuren dargestellten Ausführungsbeispiele näher erläutert werden. Es zeigen: eine schematische Ansicht eines Elektrofahrzeugs, das über ein Ladekabel an eine Ladestation anzuschließen ist; Fig. 2 eine schematische Ansicht eines beispielhaften Steckbereichs eines The idea underlying the invention will be explained in more detail with reference to the figures illustrated embodiments. It shows: a schematic view of an electric vehicle, which is to be connected via a charging cable to a charging station; Fig. 2 is a schematic view of an exemplary plug-in portion of a
Steckverbinderteils; Connector part;

Fig. 4 eine Ansicht des Trägerelements ohne die Kontaktelemente; und eine gesonderte Ansicht einer Widerstandseinrichtung mit einer Leiterplatte, einem Widerstand und Kontaktfedern zum Kontaktieren von zwei Kontaktelementen. 4 shows a view of the carrier element without the contact elements; and a separate view of a resistance device with a printed circuit board, a resistor and contact springs for contacting two contact elements.
Fig. 1 zeigt in einer schematischen Ansicht ein Fahrzeug 2, das einen elektrischen Antrieb und ein elektrisches Ladesystem mit einer Speichereinrichtung in Form von aufladbaren Batterien zur Versorgung des elektrischen Antriebs aufweist (umgangssprachlich bezeichnet auch als„Elektrofahrzeug"). Das Fahrzeug 2 kann zum Aufladen seiner Batterien über ein Ladekabel 3 an eine Ladestation 1 angeschlossen werden, wobei sowohl am Fahrzeug 2 als auch an der Ladestation 1 jeweils ein Steckverbinderteil 20, 10 in Form einer Ladebuchse vorgesehen ist, die mit Steckverbinderteilen 30, 31 in Form von Ladesteckern des Ladekabels 3 in Eingriff gebracht werden können. Ist das Fahrzeug 2 über das Ladekabel 3 an die Ladestation 1 angeschlossen, kann über ein Kabel 32 des Ladekabels 3 elektrischer Strom zum Aufladen der Batterien des Fahrzeugs 2 hin zum Fahrzeug 2 fließen.
Ein Ladestrom kann grundsätzlich als Gleichstrom oder als Wechselstrom übertragen werden, und entsprechend können das Ladekabel 3 und die verwendeten Steckverbinderteile 10, 20, 30, 31 in unterschiedlicher weise ausgestaltet sein. 1 shows a schematic view of a vehicle 2 which has an electric drive and an electric charging system with a storage device in the form of rechargeable batteries for supplying the electric drive (colloquially referred to as "electric vehicle") its batteries are connected via a charging cable 3 to a charging station 1, wherein both the vehicle 2 and the charging station 1 each have a connector part 20, 10 is provided in the form of a charging socket with connector parts 30, 31 in the form of charging plugs of the charging cable. 3 If the vehicle 2 is connected to the charging station 1 via the charging cable 3, electrical current for charging the batteries of the vehicle 2 towards the vehicle 2 can flow via a cable 32 of the charging cable 3. A charging current can in principle be transmitted as direct current or as alternating current, and correspondingly the charging cable 3 and the connector parts 10, 20, 30, 31 used can be designed in different ways.
Fig. 2 zeigt schematisch einen Steckbereich 5 eines Steckverbinderteils 20, der als Ladebuchse beispielsweise an einem Fahrzeug 2 angeordnet sein und zur Übertragung eines Ladestroms in Form eines einphasigen Wechselstroms dienen kann. Das Steckverbinderteil 20 umfasst in seinem Steckbereich 5 fünf Kontakte, von denen zwei Kontakte K1 , K2 als Lastkontakte zum Übertragen des Wechselstroms hin zum Fahrzeug 2 dienen. Über die Lastkontakte K1 , K2 kann ein einphasiger Wechselstrom beispielsweise von einer üblichen Steckdose hin zum Fahrzeug 2 übertragen werden, so dass das Fahrzeug 2 durch Anschließen an eine Steckdose und somit über das übliche Energieversorgungsnetz versorgt werden kann (die Lastkontakte K1 , K2 werden in diesem Fall auch L- und N-Leiter bezeichnet). Der Steckbereich 5 weist weiter einen Schutzleiterkontakt PE, der mit einem Schutzleiter verbunden ist, einen Pilotkontakt CP zum Übertragen von Steuersignalen und einem Annäherungskontakt PP auf. Fig. 2 shows schematically a plug-in portion 5 of a connector part 20, which may be arranged as a charging socket, for example on a vehicle 2 and may serve to transmit a charging current in the form of a single-phase alternating current. The connector part 20 comprises five contacts in its plug-in region, of which two contacts K1, K2 serve as load contacts for transmitting the alternating current to the vehicle 2. Via the load contacts K1, K2, a single-phase alternating current can be transmitted, for example, from a conventional socket to the vehicle 2, so that the vehicle 2 can be supplied by connecting to a socket and thus via the usual power supply network (the load contacts K1, K2 are in this Case also called L and N conductors). The plug-in area 5 further has a protective conductor contact PE, which is connected to a protective conductor, a pilot contact CP for transmitting control signals and a proximity contact PP.
Anzumerken ist an dieser Stelle, dass das in Fig. 2 dargestellte Steckverbinderteil 20 mit der Konfiguration seiner Kontakte K1 , K2, CP, PE, PP lediglich beispielhaft zu verstehen ist. Grundsätzlich kann auch eine andere Kontaktkonfiguration, beispielsweise zur Übertragung eines Dreiphasen-Wechselstroms oder zur Übertragung eines Gleichstroms vorgesehen sein, wobei abhängig von der Auslegung des Steckverbinderteils 20 die Anzahl der Kontakte K1 , K2, CP, PE, PP variieren kann. Ein Steckverbinderteil 20 zum Übertragen eines Dreiphasen-Wechselstroms weist beispielsweise üblicherweise vier Lastkontakte zum Übertragen des Dreiphasen- Wechselstroms und insgesamt sieben Kontakte auf. It should be noted at this point that the connector part 20 shown in Fig. 2 with the configuration of its contacts K1, K2, CP, PE, PP is to be understood merely by way of example. In principle, another contact configuration, for example for transmitting a three-phase alternating current or for transmitting a direct current, may also be provided, wherein the number of contacts K1, K2, CP, PE, PP may vary depending on the design of the connector part 20. For example, a connector part 20 for transmitting a three-phase alternating current usually has four load contacts for transmitting the three-phase alternating current and a total of seven contacts.
Bei Ladesteckern und Ladebuchsen ist üblicherweise eine Widerstandskodierung vorgesehen, die dazu dient, eine Kenninformation eines Steckverbinderteils 10, 20, 30, 31 oder eines Ladesystems, wie z. B. des Ladekabels 3 oder eines Ladesystems des Fahrzeugs 2, zu kodieren. Über die Widerstandskodierung kann beispielsweise kodiert sein, für welchen Ladestrom ein Ladesystem, beispielsweise das Ladekabel 3, ausgelegt ist, beispielsweise 16 A oder 32 A. Mittels einer solchen Widerstandskodierung, die beispielsweise von der Ladestation 1 ausgelesen werden kann, kann beispielsweise die Ladestation 1 erkennen, welcher Ladestrom maximal zulässig ist, so dass ein über ein Ladekabel 3 übertragener Ladestrom limitiert werden
kann und somit sichergestellt ist, dass das Ladekabel 3 oder ein über das Ladekabel 3 angeschlossenes Fahrzeug 2 nicht überlastet wird. In charging plugs and charging sockets usually a resistance coding is provided, which serves a characteristic information of a connector part 10, 20, 30, 31 or a charging system, such. B. the charging cable 3 or a charging system of the vehicle 2 to encode. By way of example, the resistor coding may encode for which charging current a charging system, for example the charging cable 3, is designed, for example 16 A or 32 A. By means of such a resistance coding, which can be read out, for example, from the charging station 1, the charging station 1 can recognize it , which charging current is maximum permissible, so that a charge current transmitted via a charging cable 3 is limited can and thus ensures that the charging cable 3 or connected via the charging cable 3 vehicle 2 is not overloaded.
Zur Widerstandskodierung ist, wie bei dem Ausführungsbeispiel gemäß Fig. 3 bis 5 dargestellt, eine Widerstandseinrichtung 4 an einem Trägerelement 200 eines Steckverbinderteils 20 angeschlossen derart, dass ein auf einer Leiterplatte 43 angeordneter Widerstand 40 elektrisch zwischen zwei Kontaktelemente 50, 51 , zugeordnet den Kontakten PP und PE (siehe Fig. 2), geschaltet ist. Über die Kontakte PP, PE kann der Widerstandswert des Widerstands 40 ausgelesen werden, wobei anhand des Widerstandswerts eine Kenninformation, beispielsweise ein maximal zulässiger Ladestrom, kodiert ist, so dass durch Messen des Widerstandswerts auf die Kenninformation zurückgeschlossen werden kann. For resistance coding, as shown in the embodiment of FIGS. 3 to 5, a resistance device 4 connected to a support member 200 of a connector part 20 such that a arranged on a circuit board 43 resistor 40 is electrically connected between two contact elements 50, 51, the contacts PP and PE (see Fig. 2). The resistance value of the resistor 40 can be read out via the contacts PP, PE, with characteristic information, for example a maximum permissible charging current, being coded based on the resistance value, so that the characteristic information can be deduced by measuring the resistance value.
An dem Trägerelement 200 sind in dem dargestellten Ausführungsbeispiel insgesamt fünf Kontaktelemente 50-54 in Form von Kontaktstiften zur Bereitstellung der fünf Kontakte K1 , K2, CP, PE, PP angeordnet. Die Kontaktelemente 50-54 sind hierbei jeweils im Wesentlichen rotationssymmetrisch ausgestaltet und mit einem Bund 501-541 in eine zugeordnete Aufnahmeöffnung 202-206 des Trägerelements 200 eingesteckt, so dass über das Trägerelement 200 die Kontaktelemente 50-54 ortsfest in Position gehalten werden. In the illustrated embodiment, a total of five contact elements 50-54 in the form of contact pins for providing the five contacts K1, K2, CP, PE, PP are arranged on the carrier element 200. In this case, the contact elements 50-54 are configured in each case substantially rotationally symmetrical and are inserted with a collar 501-541 into an associated receiving opening 202-206 of the carrier element 200, so that the contact elements 50-54 are held in position in position via the carrier element 200.
Die Kontaktelemente 50-54 sind derart formschlüssig an dem Trägerelement 200 angeordnet, dass die Kontaktelemente 50-54 stiftartig über einen Boden 207 des Trägerelements 200 hinaus vorstehen. Mit ihren vorstehenden Enden können die Kontaktelemente 50-54 mit einem zugeordneten anderen Steckverbinderteil elektrisch kontaktierend in Eingriff gebracht werden, so dass über die Kontaktelemente 50-54 ein anderes Steckverbinderteil, beispielsweise ein Stecker 31 eines Ladekabels 3, an das Steckverbinderteil 20 angeschlossen werden kann. Die Widerstandseinrichtung 4 ist mit ihrer Leiterplatte 43 in eine Halteeinrichtung 201 des Trägerelements 200 eingesteckt, so dass die Widerstandseinrichtung 4 formschlüssig an dem Trägerelement 200 gehalten ist. Die Halteeinrichtung 201 ist an dem Boden 207 des Trägerelements 200 angeordnet, so dass die Widerstandseinrichtung 4 an dem Boden 207 des Trägerelements 200 gehalten ist. The contact elements 50-54 are arranged in such a form-fitting manner on the carrier element 200 that the contact elements 50-54 project in a pin-like manner over a bottom 207 of the carrier element 200. With their protruding ends, the contact elements 50-54 can be electrically contacted with an associated other connector part, so that via the contact elements 50-54 another connector part, such as a plug 31 of a charging cable 3, can be connected to the connector part 20. The resistance device 4 is inserted with its printed circuit board 43 into a holding device 201 of the carrier element 200, so that the resistance device 4 is held in a form-fitting manner on the carrier element 200. The holding device 201 is arranged on the bottom 207 of the carrier element 200, so that the resistance device 4 is held on the bottom 207 of the carrier element 200.
Wie aus der gesonderten Ansicht gemäß Fig. 5 ersichtlich, sind die elastisch federnd aus metallenen Federstreifen ausgebildeten Kontaktfedern 41 , 42 an unterschiedlichen
Seiten 430, 431 der Leiterplatte 43 angeordnet, so dass die Kontaktfedern 41 , 42 zu unterschiedlichen Seiten 430, 431 von der Leiterplatte 43 vorstehen. Jede Kontaktfeder 41 , 42 weist hierbei eine Kontaktfläche 410, 420 auf, die von der Seite 430, 431 der Leiterplatte 43, an der die jeweilige Kontaktfeder 41 , 42 angeordnet ist, beabstandet ist. Die Kontaktflächen 410, 420 liegen somit von der jeweils zugeordneten Oberfläche der Leiterplatte 43 ab und sind über jeweils einen Federarm elastisch federnd an die Leiterplatte 43 angebunden. As can be seen from the separate view according to FIG. 5, the resilient springs made of metal spring strips contact springs 41, 42 are at different Pages 430, 431 of the circuit board 43 arranged so that the contact springs 41, 42 project to different sides 430, 431 of the circuit board 43. Each contact spring 41, 42 in this case has a contact surface 410, 420 which is spaced from the side 430, 431 of the printed circuit board 43, on which the respective contact spring 41, 42 is arranged. The contact surfaces 410, 420 are thus from the respective associated surface of the circuit board 43 and are connected via a spring arm elastically resiliently connected to the circuit board 43.
Die Kontaktfedern 41 , 42 und der Widerstand 40 sind bei dem dargestellten Ausführungsbeispiel als SMD-Bauteile ausgestaltet und somit auf der jeweils zugeordneten Oberfläche der Leiterplatte 43 montiert. An der Leiterplatte 43 sind geeignete Leiterbahnen zur elektrischen Kontaktierung des Widerstands 40 einerseits mit der ersten Kontaktfeder 41 und andererseits mit der zweiten Kontaktfeder 42 vorgesehen, so dass der Widerstand 40 elektrisch mit beiden Kontaktfedern 41 , 42 verbunden ist. The contact springs 41, 42 and the resistor 40 are configured in the illustrated embodiment as SMD components and thus mounted on the respectively associated surface of the circuit board 43. On the circuit board 43 suitable tracks for electrical contacting of the resistor 40 are provided on the one hand with the first contact spring 41 and on the other hand with the second contact spring 42, so that the resistor 40 is electrically connected to two contact springs 41, 42.
In montiertem Zustand, dargestellt in Fig. 3, ist die Leiterplatte 43 in die Halteeinrichtung 201 des Trägerelements 200 eingesteckt und somit an dem Trägerelement 200 gehalten. Bei an das Trägerelement 200 angesetzten Kontaktelementen 50-54 stehen die Kontaktfedern 41 , 42 über ihre Kontaktflächen 410, 420 mit zylindrischen Kontaktabschnitten 500, 510 der zugeordneten Kontaktelemente 50, 51 (Kontakte PP, PE) in Anlage, wobei die Anlage unter zumindest geringfügiger Federvorspannung erfolgt, so dass eine zuverlässige elektrische Kontaktierung der Kontaktfedern 41 , 42 mit den zugeordneten Kontaktelementen 50, 51 gewährleistet ist. In the assembled state, shown in Fig. 3, the circuit board 43 is inserted into the holding device 201 of the support member 200 and thus held on the support member 200.

Die Kontaktabschnitte 500, 510 der Kontaktelement 50, 51 schließen an den jeweiligen Bund 501 , 541 des zugeordneten Kontaktelements 50, 51 an und stehen über den Boden 207 des Trägerelements 200 hinaus vor, so dass die Kontaktfedern 41 , 42 elektrisch kontaktierend mit den Kontaktabschnitten 500, 510 in Anlage gebracht werden können. The contact portions 500, 510 of the contact elements 50, 51 adjoin the respective collar 501, 541 of the associated contact element 50, 51 and protrude beyond the bottom 207 of the carrier element 200, so that the contact springs 41, 42 are electrically contacting the contact sections 500 , 510 can be brought into contact.
Das Trägerelement 200 ist aus einem elektrisch isolierenden Material, beispielsweise einem Kunststoffmaterial, hergestellt. Die Leiterplatte 43 kann aus üblichen Leiterplattenmaterialien, beispielsweise aus einer mit Epoxidharz getränkten Glasfasermatte, hergestellt sein, wobei Leiterbahnen auf einer oder auf beiden Seiten 430, 431 der Leiterplatte 43 angeordnet sein können. Gegebenenfalls können auch
noch weitere elektrische oder elektronische Bauelemente auf der Leiterplatte 43 angeordnet sein. The carrier element 200 is made of an electrically insulating material, for example a plastic material. The printed circuit board 43 can be made of conventional printed circuit board materials, for example of a fiberglass mat impregnated with epoxy resin, whereby printed conductors can be arranged on one or both sides 430, 431 of the printed circuit board 43. If necessary, too still further electrical or electronic components may be arranged on the circuit board 43.
Der der Erfindung zugrunde liegende Gedanke ist nicht auf die vorangehend geschilderten Ausführungsbeispiele beschränkt, sondern lässt sich grundsätzlich auch bei gänzlich anders gearteten Ausführungsformen verwirklichen. The idea underlying the invention is not limited to the above-described embodiments, but can in principle be realized even in completely different types of embodiments.
Insbesondere ist das Vorsehen einer Widerstandskodierung der hier beschriebenen Art grundsätzlich bei beliebigen Konfigurationen von Steckverbinderteilen zur Übertragung von Gleichstrom oder Wechselstrom denkbar und möglich. Eine Widerstandskodierung kann auch bei so genannten Kombo-Steckern, die sowohl zur Übertragung von Wechselstrom als auch zur Übertragung von Gleichstrom verwendet werden können, zum Einsatz kommen.
In particular, the provision of a resistance coding of the type described here is basically conceivable and possible in any configurations of connector parts for the transmission of direct current or alternating current. A resistance coding can also be used in so-called combo plugs, which can be used both for the transmission of alternating current as well as for the transmission of direct current.
