Im Bereich Internet-of-Things loT (Internet der Dinge) sind typischerweise Sensoren und/oder Aktoren über Kabel (oder drahtlos) mit einem Netzwerk verbunden, um eine Kommunikation mit Diensten in dem Netzwerk zu erlauben. Eine Kommunikation der Sensoren und/oder Aktoren und den Diensten in dem Netzwerk kann beispielsweise auf einem IP- Protokoll basieren. In the area of Internet of Things loT (Internet of Things), sensors and / or actuators are typically connected to a network via cables (or wirelessly) in order to allow communication with services in the network. Communication between the sensors and / or actuators and the services in the network can be based on an IP protocol, for example.
Typischerweise werden loT Geräte über Ethernetleitungen an ein Netzwerk angeschlossen, um eine Datenübertragung zu ermöglichen. Elektromagnetische Verträglichkeit EMV Schutzmaßnahmen werden hierbei in den loT Geräten implementiert. Typically, loT devices are connected to a network via Ethernet cables to enable data transmission. Electromagnetic compatibility EMC protective measures are implemented in the loT devices.
Es ist eine Aufgabe der Erfindung, einen elektromagnetische Verträglichkeit EMV Schutz für loT Geräte zu verbessern. It is an object of the invention to improve electromagnetic compatibility EMC protection for loT devices.
Diese Aufgabe wird durch einen Stecker für Internet-of-Things Geräte nach Anspruch 1 gelöst. This object is achieved by a plug for Internet of Things devices according to claim 1.
Gemäß der Erfindung wird ein Stecker zum Verbinden mit einem loT Gerät vorgesehen, der ein Gehäuse und eine Leiterkarte aufweist. Das erste Ende der Leiterkarte ist mit einem hybriden Single Pair Ethernet Kabel verbunden. Am anderen Ende der Leiterkarte ist ein Steckgesicht mit Kontaktflächen vorgesehen, mittels welcher der Stecker mit einem loT Gerät gekoppelt werden kann. Auf der Leiterkarte ist eine elektromagnetische Verträglichkeit EMV Schutzeinheit vorgesehen. Der EMV Schutz wird somit innerhalb des Steckgehäuses vorgesehen. According to the invention, a plug for connecting to a loT device is provided, which has a housing and a printed circuit board. The first end of the circuit card is connected with a hybrid single pair Ethernet cable. At the other end of the circuit card, a plug face with contact surfaces is provided, by means of which the plug can be connected to a loT Device can be paired. An electromagnetic compatibility EMC protection unit is provided on the circuit board. The EMC protection is thus provided within the plug-in housing.
Gemäß einem Aspekt der Erfindung ist eine Dichtung im Bereich des zweiten Endes der Leiterkarte zwischen dem Steckgesicht und dem Gehäuse vorgesehen. Somit wird ein durch das Gehäuse und die Dichtung abgedichteter Raum oder Bereich vorgesehen. According to one aspect of the invention, a seal is provided in the area of the second end of the printed circuit card between the plug face and the housing. Thus, a space or area sealed by the housing and the seal is provided.
Gemäß einem Aspekt der Erfindung wird ein Rastelement außerhalb des abgedichteten Bereichs an dem Gehäuse vorgesehen. According to one aspect of the invention, a latching element is provided on the housing outside the sealed area.
Gemäß einem Aspekt der Erfindung wird eine typischerweise in einem Stecker für ein loT Gerät vorhandene Leiterkarte dazu verwendet, auch eine EMV Schutzmaßnahme aufzunehmen. Mit anderen Worten, eine EMV Schutzmaßnahme wird in ein Gehäuse eines Steckers für loT Geräte integriert. According to one aspect of the invention, a printed circuit card typically present in a plug for a loT device is used to also accommodate an EMC protective measure. In other words, an EMC protective measure is integrated into a housing of a connector for loT devices.
Gemäß einem Aspekt der Erfindung sind die Gehäuse der Stecker um 90 bezogen auf eine Leiterkarte des loT Gerätes gedreht. Die Stecker werden somit hochkant mit der Lei- terkarte des loT Gerätes gekoppelt. According to one aspect of the invention, the housings of the plugs are rotated by 90 in relation to a circuit card of the loT device. The plugs are thus coupled upright with the circuit board of the loT device.
Gemäß einem Aspekt der Erfindung ist die Leiterkarte mittig zur langen Steckgesichtseite angeordnet und parallel zur kurzen Achse des Steckgesichtes ausgerichtet. According to one aspect of the invention, the circuit card is arranged in the middle of the long plug face side and is aligned parallel to the short axis of the plug face.
Gemäß der relevanten europäischen EMV-Norm ist bei hybriden Single Pair Ethernet Geräten ab einer Anschlussleitungslänge von 30m ein Schutz gegen Stoßspannungen (Surge) notwendig. Gemäß einem Aspekt der Erfindung wird ein hybrides Single Pair Ethernet Kabel mit einem oben beschriebenen Stecker zum Verbinden mit einem Internet of Things Gerät vorgesehen, welches eine größere Anschlussleitungslänge als 30m zulässt, auch wenn das Gerät keine Schutzbeschaltung gegen Stoßspannungen (Surge) aufweist. Somit kann durch Einsatz der Stecker gemäß einem Aspekt der vorliegenden Erfin- düng die maximale Länge der verwendbaren Kabel gesteigert werden. According to the relevant European EMC standard, hybrid single pair Ethernet devices with a connecting cable length of 30m or more require protection against surge voltages. According to one aspect of the invention, a hybrid single pair Ethernet cable with a connector described above for connecting to an Internet of Things device is provided, which allows a connection line length greater than 30m, even if the device does not have a protective circuit against surge voltages. Thus, by using the plug according to one aspect of the present invention, the maximum length of the cables that can be used can be increased.
Die notwendige Schutzbeschaltung (EMV Schutzeinheit), üblicherweise eine Spezialdiode zwischen den Gleichspannungsanschlüssen, wird in den Stecker z.B. durch rückseitiges Anlöten an die Steckkontakte eingebracht. Gemäß einem Aspekt der vorliegenden Erfindung weist der Stecker bzw. Steckverbinder einen M8 H-codierten Stecker auf. Alternativ dazu kann auch ein M8 D-codierter Stecker vorgesehen sein. Die Stecker unterstützen den Ethernet Protokoll Standard IEEE802.3. Die Stecker können nach PAS IEC61076-2-14 genormt sein. Gemäß einem Aspekt der vorliegenden Erfindung weist der Steckverbinder vier elektrische Anschlüsse auf. Von den vier elektrischen Anschlüssen dienen zwei der Gleichspannungsübertragung und zwei Anschlüsse dienen der Datenübertragung basierend auf dem Ethernet Standard. The necessary protective circuit (EMC protection unit), usually a special diode between the DC voltage connections, is inserted into the plug, for example by soldering it to the plug contacts on the back. According to one aspect of the present invention, the plug or connector has an M8 H-coded plug. Alternatively, an M8 D-coded connector can also be provided. The connectors support the Ethernet protocol standard IEEE802.3. The plugs can be standardized according to PAS IEC61076-2-14. According to one aspect of the present invention, the connector has four electrical connections. Of the four electrical connections, two are used for direct voltage transmission and two connections are used for data transmission based on the Ethernet standard.
Die Erfindung betrifft ebenfalls ein Internet-of-Things Gerät, welches einen Steckverbinder aufweist, der mit einem Stecker gemäß einem Aspekt der vorliegenden Erfindung koppelbar ist, damit das Internet-of-Things so über ein hybrides Single Pair Ethernet Kabel sowohl mit Energie als auch mit Daten und/oder Befehlen versorgt werden kann. Das Internet-of- Things wird somit über den Stecker gemäß einem Aspekt der vorliegenden Erfindung und dem sich daran befindlichen hybriden Single Pair Ethernet Kabel vorgesehen, um mit ei- nem Netzwerk kommunizieren zu können. The invention also relates to an Internet of Things device which has a connector that can be coupled to a plug according to one aspect of the present invention, so that the Internet of Things can be supplied with both power and energy via a hybrid single pair Ethernet cable can be supplied with data and / or commands. The Internet of Things is thus provided via the connector according to one aspect of the present invention and the hybrid single pair Ethernet cable located on it, in order to be able to communicate with a network.
Gemäß einem Aspekt der vorliegenden Erfindung weist das Internet-of-Things Gerät optional lediglich eine Schnittstelle, nämlich den Steckverbinder, auf. Damit verfügt das Inter- net-of-Things Gerät weder über eine Tastatur noch über ein Display noch weitere Schnittstellen zur Konfiguration durch den Benutzer. Optional kann ein Web-basiertes User Inter- face zur Einstellung der Parameter des Gerätes verwendet werden. According to one aspect of the present invention, the Internet of Things device optionally has only one interface, namely the connector. This means that the Internet of Things device has neither a keyboard nor a display, nor any other interfaces for configuration by the user. Optionally, a web-based user interface can be used to set the parameters of the device.

The plug 100 is used to couple an Internet of Things device (loT device) to a network using a hybrid single pair Ethernet cable.
Vorteilhafterweise sind die EMV Schutzeinheiten in dem Gehäuse 6 des Steckers 100 integriert, so dass eine kompakte Ausgestaltung von Stecker und loT Gerät im gesteckten Zustand durch teilweise oder vollständige Verlagerung des EMV Schutzes aus dem loT Gerät in den Stecker erreicht wird. Das Kabel 1 stellt gemäß einem Aspekt der Erfindung eine 4-polige T1 Verbindung dar, d.h. es handelt sich hierbei um eine hybride Single Pair Ethernet Leitung SPE. The EMC protection units are advantageously integrated in the housing 6 of the plug 100, so that a compact design of the plug and loT device when plugged in is achieved by partially or completely relocating the EMC protection from the loT device to the plug. According to one aspect of the invention, the cable 1 represents a 4-pin T1 connection, ie it is a hybrid single pair Ethernet line SPE.
Fig. 2 zeigt eine schematische perspektivische Darstellung eines Steckers gemäß einem zweiten Ausführungsbeispiel der Erfindung. In Fig. 2 sind die Stecker 100 hochkant vorge- sehen, so dass eine platzsparende Verbindung von mehreren Steckern mit einem loT Gerät 200 ermöglicht wird. Das loT Gerät 200 weist eine Leiterkarte 11 auf, mit welchem die Stecker 100 gekoppelt werden. Insbesondere sind die Stecker 100 um 90° zur Leiterkarte 11 des loT Gerätes 200 gedreht. Dies ist insbesondere vorteilhaft, da die Bedienbarkeit der Stecker verbessert wird, da der Nutzer besser an die einzelnen Stecker herankommt. Fer- ner können mehrere Stecker bei geringerem Raumbedarf mit dem loT Gerät 200 gekoppelt werden. Insbesondere werden auf Steckseite lediglich Kontaktflächen und keine Bauteile für die Kontaktierung benötigt. Fig. 2 shows a schematic perspective illustration of a plug according to a second embodiment of the invention. In FIG. 2, the plugs 100 are provided upright, so that a space-saving connection of several plugs with a loT device 200 is made possible. The loT device 200 has a printed circuit board 11, with which the plug 100 is coupled. In particular, the plugs 100 are rotated by 90 ° to the printed circuit board 11 of the loT device 200. This is particularly advantageous since the usability of the connector is improved since the user has better access to the individual connectors. In addition, several plugs can be coupled to the loT device 200 if less space is required. In particular, only contact surfaces and no components are required for contacting on the plug side.
Da der Stecker bereits über wenigstens ein Rastelement verfügt, muss die Leiterkarte des loT Gerätes nicht über ein Rastelement verfügen. Der Stecker 100 gemäß dem zweiten Ausführungsbeispiel entspricht dem Stecker gemäß dem ersten Ausführungsbeispiel. Since the plug already has at least one locking element, the circuit card of the loT device does not have to have a locking element. The connector 100 according to the second exemplary embodiment corresponds to the connector according to the first exemplary embodiment.
Das Kabel 1 stellt gemäß dem zweiten Ausführungsbeispiel der Erfindung eine 4-polige T 1 Verbindung dar, d.h. es handelt sich hierbei um eine hybride Single Pair Ethernet Leitung SPE. Fig. 3 zeigt eine schematische perspektivische Darstellung eines Steckers gemäß einem dritten Ausführungsbeispiel der Erfindung. Der Stecker 100 gemäß dem dritten Ausführungsbeispiel entspricht im Wesentlichen dem Stecker gemäß dem ersten Ausführungsbeispiel. Gegenüber dem ersten und zweiten Ausführungsbeispiel ist die Leiterkarte im Stecker um 90 gedreht, wodurch diese co-planarzur Leiterkarte im loT Gerät ausgerichtet ist und im loT Gerät übliche Buchsen zur Kontaktierung verwendet werden können. According to the second exemplary embodiment of the invention, the cable 1 represents a 4-pin T 1 connection, i.e. it is a hybrid single pair Ethernet line SPE. 3 shows a schematic perspective illustration of a plug according to a third exemplary embodiment of the invention. The connector 100 according to the third exemplary embodiment corresponds essentially to the connector according to the first exemplary embodiment. Compared to the first and second exemplary embodiment, the circuit card in the plug is rotated by 90, so that this co-planar is aligned with the circuit card in the loT device and conventional sockets can be used for contacting in the loT device.
Gemäß einem Aspekt der Erfindung ist der Stecker um 180° verdreht in das loT Gerät steckbar. Dies wird erreicht durch die doppelte Auslegung der Kontaktflächen, welche jeweils auf Ober- und Unterseite der Leiterkarte vorhanden sind, wobei die Anordnung auf beiden Seiten gleich ist. Zusätzlich kann die Buchse im IoT-Gerät mittig im Steckgesicht positioniert sein. Gemäß einem Aspekt der Erfindung ist die Leiterkarte im Stecker aus einem besonderen Material (Wasserverträglichkeit, Abnutzungsverhalten, Stabilität, ...) wie z.B. Keramik hergestellt und kann so ohne weiteren Schutz im Steckgesicht genutzt werden. According to one aspect of the invention, the plug can be plugged into the loT device rotated by 180 °. This is achieved through the double design of the contact surfaces, which are present on the top and bottom of the circuit board, the arrangement being the same on both sides.
