Abstract

The invention relates to a hybrid plug connector system (100) for transmitting power and data. The plug connector system has a plug (110) with a plug / cable interface (110a) for wired data and energy transmission, and a plug interface (112) for wired energy transmission and wireless data transmission. The plug connector system (100) also has at least one complementary socket (120) with a socket interface (122) which is designed to be complementary to the plug interface (112). The plug connector system allows energy and data to be transmitted between devices (consumers and generators) connected to the plug / cable interface (110a) and the socket / cable interface (126), wherein the radio plug wireless transmitter and / or receiver (114) and the radio socket wireless transmitter and / or receiver (123) allow wireless transmission with a high bandwidth and short range, in particular in the 60 GHz band. As a result of the wireless data transmission within the plug connector system, the fragile and error-prone data contacts of the plug connection which are otherwise necessary are dispensed with, as a result of which the connector mechanism can have a simpler design and the data connection is more reliable. As a result, the use of hybrid connections between generators and consumers of high power is simplified and allows plug 'n' play, for example for load management or current direction reversal in electrical systems.

[0003] Hybrid connector system

[0004] The present invention relates to a hybrid connector system.

[0005] Hybrid connector systems for both data and power (energy transmission) are becoming increasingly important, replacing separate connectors for power and signals. A fundamental problem with hybrid connectors (plug and socket) can be the mechanical discrepancy between the power contacts (rough) and the data contacts (precise and fine). When contacting connectors, care must be taken to ensure that the data contacts are not damaged during insertion and removal. Furthermore, it is essential to protect the data contacts from contamination.

[0006] The German Patent and Trade Mark Office has searched the following documents in the German patent application that establishes the priority of the present application: DE 20 2020 103 990 U1 , DE 10 2015 216 060 A1 , DE 10 2016 104 196 A1 , DE 10 2010 045 131 A1 and DE 10 2010 045 329 A1 .

[0007] It is an object of the present invention to provide a hybrid connector system that at least partially overcomes the aforementioned disadvantages or meets the aforementioned requirements. In particular, it is an object to provide an improved connector system.

[0008] This problem is solved by a hybrid connector system according to claim 1.

[0009] Thus, a hybrid connector system for power and / or data transmission is provided, comprising a plug and a complementary socket. The hybrid connector system is therefore used to transmit power, data, or a combination of both. The connector system features a plug with a cable interface for wired data and power transmission, as well as a plug interface for wired power transmission and a wireless transmitter and / or receiver for wireless radio data transmission between the plug and socket, or vice versa.The connector system further comprises at least one socket complementary to the plug, with a socket interface that is designed to be complementary to the plug interface and allows a galvanic connection between the plug interface and the socket interface to transmit power from the plug to the socket or vice versa. The socket also includes a wireless transmitter and / or receiver for wireless radio data transmission between the plug and the socket or vice versa. The connector system is suitable for transmitting power galvanically coupled between the plug cable interface and the socket interface and for transmitting data wirelessly between them, in particular by tunneling.

[0010] The wireless plug transmitter and / or receiver and the wireless socket transmitter and / or receiver can allow wireless radio transmission with high bandwidth and short range.

[0011] Wireless radio transmission can be based on the IEEE 802.11ad or IEEE 802.11ay standard.

[0012] The connector thus features a plug-cable interface (for connecting to a cable for data and power transmission) and a plug interface (for coupling with a socket interface). The socket features a socket-cable interface (for connecting to a cable for data and power transmission) and a socket interface (for coupling with the plug interface). Power can be transmitted in both directions (from plug to socket or vice versa) via galvanic and mechanical coupling (plug interface and socket interface). Data can be transmitted wirelessly and via radio link between the plug and socket, or vice versa. The hybrid connector system therefore serves to transmit both power and data.

[0013] The hybrid connector enables Ethernet communication between two devices, each connected via a cable, with the cables themselves connected by the hybrid connector. The hybrid connector features a plug with a wireless transmitter / receiver and a socket with a wireless transmitter / receiver. The wired Ethernet communication is thus interrupted by the wireless interface. The wireless transmission between the plug and socket is designed to allow transparent Ethernet communication. This can be achieved, for example, by using an IEEE 802.11ad or IEEE 802.11ay standard for the wireless transmission. This provides a wireless transmission protocol suitable for Ethernet communication. For example, the bandwidth can be 10 / 100 / 1000 Mbit / s.The wireless plug-in transmitter / receiver and the wireless socket-inlet transmitter / receiver are each designed as media converters capable of converting wired Ethernet communication into wireless Ethernet communication. Specifically, a 1:1 connection is established between the wireless plug-in transmitter / receiver and the wireless socket-inlet transmitter / receiver.

[0014] The hybrid connector system thus enables seamless Ethernet communication between two devices via two Ethernet cables and the hybrid connector, even though two different transmission media (namely cable and radio link) are used.

[0015] Thus, a first device at one end of a first cable can communicate directly with a second device at the end of a second cable using Ethernet communication. Both devices are visible to each other via Ethernet. For example, an electric car (first device) connected to a wallbox via a hybrid connector can communicate directly with a second device via the same hybrid connector. The second device can see, via Ethernet communication, that an electric car is connected to the wallbox and which one. Direct Ethernet communication is possible with the hybrid connector, which allows wireless Ethernet communication.

[0016] The plug and socket can each have a housing, which may be made of metal. This can provide electromagnetic shielding.

[0017] The respective cable interfaces allow the socket and plug to be connected to electrical and / or electronic devices between which power and data are to be exchanged. The cable interfaces can be connected to cables, circuit boards, or electronic components. The plug interface and the socket interface each represent a mating face of the connector. The cable interfaces can therefore be located on the mating face of the plug or socket. The plug wireless transmitter and / or receiver can be configured as a transceiver (i.e., as a transmitter and receiver for sending and receiving), as a transmitter for sending, or as a receiver for receiving. The socket wireless transmitter and / or receiver can be configured as a transceiver (i.e., as a transmitter and receiver for sending and receiving), as a transmitter for sending, or as a receiver for receiving.

[0018] By using wireless data transmission, sensitive data contacts are eliminated, meaning the plugging mechanism of the connector system can be designed to meet the tolerances / requirements of the contacts for power transmission.

[0019] Optionally, power contacts (i.e., the plug interface and the socket interface) are provided on the plug and socket, enabling reliable power transmission between devices connected to them. By using wireless transmission, the sensitive data contacts are eliminated, meaning the plugging mechanism of the connector system can be designed to meet the tolerances / requirements of the power contacts. Using a transceiver in each case allows for bidirectional communication.

[0020] The hybrid connector system enables a significant improvement in vibration resistance, as no galvanic or mechanical coupling is required for data transmission. When designing the mechanical and galvanic coupling, only the requirements for the power contacts need to be considered. Furthermore, leakage and equalizing currents via the sheath or data lines between the power and data lines can be reduced.

[0021] The hybrid connector system consists of a plug and a socket. The power contacts, in the form of the plug and socket interfaces, are implemented conventionally using mechanical and electrical connections. The data connection, however, is wireless when the connector is plugged in (i.e., the plug is inserted into the socket or vice versa).

[0022] The power contacts can be designed to transmit a current of >16A. Since the hybrid connector system is suitable for bidirectional power and data transmission, the plug and socket can each be assigned to a (power) consumer or a (power) supplier.

[0023] Optionally, an auxiliary voltage (e.g. inductive) can be transmitted wirelessly via the wireless data connection, which allows communication before the power is switched on (through the power connection).

[0024] The plug can optionally have a plug housing, and the socket can optionally have a socket housing. Both housings can be made of metal. This is advantageous because it allows for electromagnetic shielding of the wireless data transmission.

[0025] Accordingly, the radio connection for wireless transmission can also be shielded via the connector housing, so that the data cannot be intercepted outside the connector, nor can it be disrupted from the outside. This is advantageous with regard to data security.

[0026] Furthermore, it is advantageous that the antennas of the transmitter and receiver of the wireless connection do not need to be precisely aligned and can move relative to each other even during operation. Additionally, contact interruptions on the data lines caused by vibrations or mechanical shocks can be reduced or avoided. The radio connection for short-range wireless transmission is also robust against contamination that can occur when the connector is not plugged in.

[0027] Furthermore, the wireless data connection effectively prevents unwanted equalizing currents via the data cable.

[0028] Because the wireless link is very short and defined, it can be more robust, cheaper, faster, or a combination of these properties compared to wireless transmission over longer distances with unclear environmental conditions.

[0029] Another advantage of the system is that, thanks to the hybrid interface and data tunneling (i.e., data communication can extend beyond the wireless interface), the higher-level system can implicitly recognize which consumers and suppliers are connected via the soft connection. Similar to USB plug-and-play, this enables intelligent control of currents (direction / load distribution) even in dynamically connected systems with bidirectional current flows (e.g., vehicle-to-home or battery storage). It is no longer necessary to inform the higher-level system, for example, through manual input, which generators and consumers are connected and how. In particular, this makes operation possible even for non-technical users. Optionally, controllers for plug-and-play installation can be integrated into the plug and / or socket to further enhance this functionality.This allows not only the identification of which generator is connected to which consumer, but also of which cables. Optionally, sensors (temperature) or actuators (status indicator, locking mechanism) can be integrated into the plug and / or socket.

[0030] Bidirectional data communication enables communication between the supplier and the consumer. Data can therefore be transmitted from the plug to the socket or from the socket to the plug.

[0031] Power can be transmitted bidirectionally between the plug and socket.

[0032] The connector system can be used by a power supplier or a power consumer. Furthermore, the connector system allows for a role reversal, so that the consumer transfers power to the supplier. Examples of this include power-to-home (P2H) in electric vehicles, electrical buffer storage, or recuperation of trailer braking energy into the traction battery of a towing vehicle.

[0033] The connector system can be used as a vehicle charging plug, as a connector system in power supply systems, as a connector system for electrical buffer storage, as a connector system in a tractor-implement combination, as a connector system in a tractor-trailer combination or in a train coupling.

[0034] Optionally, the wireless bidirectional data communication between socket and plug allows Ethernet communication or Single Pair Ethernet communication to be tunneled over the wireless link.

[0035] According to one aspect of the invention, a hybrid connector system for power and data transmission is provided. The connector system comprises a plug with a plug-cable interface for wired data and power transmission, as well as a plug interface for wired power transmission and wireless data transmission. The connector system further comprises at least one complementary socket with a socket interface, which is designed to be complementary to the plug interface. The connector system allows the transmission of power and data between consumers and producers (electrical and / or electronic devices) connected at the plug-cable interface and the socket-cable interface.Wireless data transmission within the connector system eliminates the otherwise necessary fragile and error-prone data contacts of the plug connection, allowing for a simpler connector mechanism and a more reliable data connection. This simplifies the use of hybrid connections between high-power generators and consumers and enables plug-and-play applications such as load management or current reversal in electrical systems.

[0036] The invention also relates to a hybrid connector for a hybrid connector system described above for power and / or data transmission. The connector has a connector-cable interface for data and power supply, a connector interface for power transmission, and a connector-wireless transmitter and / or receiver for wireless data transmission between the connector and a complementary socket or vice versa.

[0037] The invention also relates to a hybrid socket for a hybrid connector system described above for power and / or data transmission. The hybrid socket comprises a socket interface which is designed to be complementary to the plug interface and allows a galvanic connection between the plug interface and the socket interface in order to transfer power from the plug to the socket or vice versa, a socket cable interface, and a socket wireless transmitter and / or receiver for wireless data transmission between a complementary plug and socket or vice versa.

[0038] Further embodiments of the invention are the subject of the dependent claims.

[0039] The advantages and embodiments of the invention are explained in more detail below with reference to the drawing.

[0040] Fig. 1 shows a block diagram of a hybrid connector system, and

[0041] Fig. 2 shows a block diagram of a hybrid connector system.

[0042] Fig. 1 shows a block diagram of a hybrid connector system. The hybrid connector system 100 is used for transmitting voltage and / or data and comprises a plug 110 and a socket 120. The plug 110 is coupled via a plug-cable interface 110a to at least one first cable 10 for power transmission and / or data transmission. The plug 110 has a plug-voltage unit 111 and a plug-interface 112 for mechanical and galvanic coupling. Power transmitted via the cable 10 can be output by a plug 120 via the plug-voltage unit 111 and the plug-interface 112.

[0043] The socket 120 is designed to complement the plug 110 and has a socket interface 122, which can be mechanically and galvanically coupled to the plug interface 112 to transmit power. The socket 120 also has a socket voltage unit 121, which is coupled to the socket interface 122. The socket 120 has a socket cable interface 126, which can be coupled to at least one second cable or electronic device 20 to transmit power and / or data.

[0044] The first cable 10 can connect a first device 1 to the plug 110. The second cable 20 can connect the socket 120 to a second device.

[0045] Thus, power or voltage is transmitted from the first cable 10 via the plug-cable interface 110a, the plug interface 112, the socket interface 122 and the socket-cable interface 126 and the second cable 20. A galvanic and mechanical connection between the plug 110 and the socket 122 is established via the plug interface 112 and the socket interface 122 in order to achieve power or energy transmission.

[0046] For data transmission, the plug 110 has a wireless transmitter and / or receiver 114 and the socket 120 has a wireless transmitter and / or receiver 123, which together are suitable for transmitting and, in particular, tunneling data between the plug cable interface 110a and the socket cable interface 126 wirelessly, i.e., data communication can take place beyond the wireless interface, i.e., between the devices connected to the plug and socket 1. The plug wireless transmitter and / or receiver can be configured as a transceiver (i.e., as a transmitter and receiver for sending and receiving), as a transmitter for sending, or as a receiver for receiving. The socket wireless transmitter and / or receiver can be configured as a transceiver (i.e., as a transmitter and receiver for sending and receiving), as a transmitter for sending, or as a receiver for receiving.

[0047] Thus, data transmission from the plug to the socket and vice versa takes place wirelessly and without galvanic or direct mechanical connection.

[0048] Optionally, wireless data transmission between the plug-in wireless transmitter 114 and the socket-based wireless receiver 124 can take place with high bandwidth and short range. For example, this can be done in a frequency band of 60 GHz.

[0049] The radio wireless transmission can be based on the IEEE 802.11ad or IEEE 802.11ay standard or protocol.

[0050] Optionally, plug 1 10 and socket 120 have data units 113,124 (e.g. a microcontroller with suitable communication interfaces) which allow communication with the plug and / or socket via the data connection of the plug-cable interface 110a or the socket interface 126.

[0051] The plug 110 can optionally have a plug housing 110b, and the socket 120 can optionally have a socket housing 120b. Both housings 110b and 120b can be made of metal. This is advantageous because it allows for electromagnetic shielding of the wireless data transmission.

[0052] The cable interface allows the plug and socket to be connected to electrical and / or electronic devices 1 for the exchange of power and / or data. A cable, a circuit board, or electronics can be connected to the cable interface.

[0053] Fig. 2 shows a block diagram of a hybrid connector system. The plug 110 and the socket 120 are essentially the same as the plug 110 and socket 120 shown in Fig. 1. Furthermore, the plug 110 can have a plug inductive voltage unit 116. The socket 120 can have a complementary socket inductive voltage unit 127. Wireless power transfer can be achieved via the plug inductive voltage unit 116 and the socket inductive voltage unit 127. This wireless power transfer can at least partially supply power to the plug 110 or the socket 120. This can be particularly advantageous when no power or voltage is yet being transferred via the plug output interface 112 and the socket interface 122.

[0054] Optionally, connector 110 can have a sensor and / or actuator 115 for acquiring parameters or providing feedback to the operator or connector system. Similarly, socket 120 can have a sensor and / or actuator 125 for acquiring parameters or providing feedback to the operator or connector system. Acquired parameters can include, for example, temperature, humidity, vibration, operating elements, or the number of mating cycles. Actuators can include, for example, LEDs, latches, locking mechanisms, or ejection aids.

[0055] The plug 110 can optionally have a plug housing 110b, and the socket 120 can optionally have a socket housing 120b. The housings 110b and 120b can each be made of metal and can advantageously serve for electromagnetic shielding of the wireless communication. Optionally, the plug housing 110b and the socket housing 120b are substantially electromagnetically shielded. This protects the radio communication between the wireless transmitters / receivers in the plug and socket from external electromagnetic interference. Furthermore, the radio communication cannot be intercepted from the outside, which increases security.

[0056] For example, a hybrid connector system for high currents (e.g., < 16A) is combined with high-bandwidth wireless data transmission. This can improve the mechanical sensitivity of conventional data contacts and prevent signal interruptions on the data lines.

[0057] For example, an auxiliary voltage can be provided via the wireless connection for connected devices / cables, which enables communication before voltage / current is applied to the power contacts.

[0058] According to one example, galvanic isolation can be achieved on the data line (between plug and socket).

[0059] For example, the wireless connection can enable plug and socket identification. In this case, the plug and / or socket can have an identifier that can be detected wirelessly. For example, the hybrid connector system is used in vehicle charging plugs, power supply systems, or train couplings.

[0060] For example, the connector system has sensors for important parameters such as temperature, vibration load, or logging of the number of mating cycles.

[0061] For example, wireless transmission takes place with high bandwidth and short range, such as in the 60GHz band.

[0062] The radio wireless transmission can be based on the IEEE 802.11ad or IEEE 802.11ay standard or protocol.

[0063] For example, an Ethernet connection can be transparently tunneled over a wireless connection. The wireless transmitter and / or receiver (connected via a plug) and the wireless transmitter and / or receiver (connected via a socket) are not visible to the Ethernet communication. The Ethernet communication is not affected in the sense that the devices at the ends of the cables on both sides of the hybrid connector can communicate directly with each other via Ethernet.

[0064] For Ethernet communication, communication takes place, for example, via a wired Ethernet connection, interrupted by the radio transmission link, which is implemented through the hybrid connector.

[0065] Furthermore, the plug and socket can optionally each be equipped with a controller to improve or extend plug 'n' play functionality.

[0066] Hybrid connectors are special connectors that combine different types of transmission in a single housing. These transmissions can include electrical power, signals, data, or optical signals. The idea behind hybrid connectors is to bundle multiple functionalities into a single interface to save space, reduce wiring effort, and simplify installation.

[0067] Hybrid connectors can accommodate multiple transmission types. They can combine electrical or optical connections in a single housing. Integrating multiple connection types into a single connector reduces the space required in applications. Hybrid connectors can be modular, allowing them to be adapted to specific requirements. For example, one module could be for power transmission, another for data transmission, and another for optical transmission.

[0068] Hybrid connectors can be designed for industrial applications and therefore be robust enough to function under extreme conditions such as high temperatures, humidity, dust or vibrations.

[0069] Hybrid connectors are used in various fields: Industrial automation: Machines and robots often require a combination of power supply, data transmission, and signal communication. Hybrid connectors simplify wiring and increase reliability. Automotive industry: In vehicles, hybrid connectors are used for sensors, cameras, engine control units, and infotainment systems to optimize wiring and reduce weight. Telecommunications: In network equipment, hybrid connectors can combine electrical and optical transmissions to increase connection efficiency. Medical technology: Here, they are used to connect complex medical devices that need to carry power, data, and possibly even fluids through the same connection.

[0070] This results in simplified installation, as fewer connectors and cables are required, enabling faster and easier installation. Furthermore, it saves space; especially in applications where space is limited, hybrid connectors offer a compact solution. Additionally, it allows for reduced maintenance: fewer individual connections also mean fewer potential sources of error and therefore greater reliability.
