Description

Technical Field

[0001] This invention relates to an electrical connector. It also relates to a method for operating a system having an electrical connector, wherein the connector includes a sensor device for detecting one or more electrical operating parameters. Background Technology

[0002] Connectors are used in many fields, such as manufacturing and automation, to interconnect electrical current and other devices. One challenge here is ensuring the functionality of cables and connectors and quickly identifying potentially damaged components when connection problems occur.

[0003] For example, in known solutions, the power supply unit is equipped with a display or other form of information display scheme, such as a scheme provided through a communication interface, where current power data is output based on voltage and current intensity data. Furthermore, diagnostic information can be generated for the relevant equipment in the event of undervoltage, overvoltage, or power outage.

[0004] One of the problems that connectors may solve is monitoring the power supply and cable status of the cables connected to them. Summary of the Invention

[0005] The object of this invention is to provide an electrical connector that can ensure particularly reliable and efficient use of established electrical connections or existing power distribution networks.

[0006] The electrical connector includes a housing, at least one input-side contact, at least one output-side contact, and circuitry, the circuitry being disposed inside the housing. Here, the circuitry includes a sensor device, a control device, and a communication interface. The sensor device is configured to detect electrical operating parameters, and the control device is configured to generate output data based on the electrical operating parameters and output the output data via the communication interface.

[0007] The circuit may include, for example, a power supply circuit, a sensor circuit, a microprocessor, and a remote communication module, particularly a radio module.

[0008] In the operation of equipment using connectors of known embodiments, damage may occur in the power supply lines, power distribution components such as Y-type power distribution units, connectors or extension cables, or on the powered equipment. As a result, an entire part of the equipment may fail, and it is extremely tedious to determine where the connection was interrupted or where the damage occurred. Consequently, the equipment is shut down for extended periods.

[0009] Now, the electrical connector according to the invention allows for continuous measurement of voltage and / or current intensity between power supply pins at corresponding connection points in the power supply line, for example, directly at the pins of the connector. Furthermore, the detected values ​​can be transmitted and / or stored for later output. This is done in the connector of the power supply line, or using a measurement point pre-installed for initial operation, for example, using an M12 to M12 measurement bridge with the same characteristics as the connector. For example, the voltage difference measured at different power supply points can be used as information to evaluate device operation in further investigation.

[0010] For example, the voltage and / or current difference detected at the power supply measurement point can be mainly used for: - Ensure that the equipment to be powered has sufficient operating voltage during operation; - Determine the voltage drop on the power supply line; - Continuously determine the operating current with known conductor resistance, for example, during a test run, by utilizing the voltage difference of a current source to determine the conductor resistance; - Evaluate the voltage drop over time to identify, for example, load peaks or detect deteriorating cable quality; - Status detection means continuously detecting the status of electrical connections and / or data connections; - Export the overall health status of a system's equipment and plan maintenance intervals; and / or - Quickly locate the source of the fault, especially in the way of locating potential cable faults or cable failures.

[0011] In the automation industry, device connectors with pre-fabricated cables are used to transmit signals and / or power to actuators and sensors. An example is the M12 connector, which uses multiple pins and corresponding wires to connect to equipment and mating cables. This connection is typically sealed against water and dust.

[0012] This connection is used, for example, to connect a voltage source to field devices and / or sensors and provide them with power. This is done according to the so-called star or daisy-chain distribution principle. In the first case, the devices to be powered are each powered through a power supply line leading to the voltage source (logic star). In the second case, the first device is connected to the voltage source, and other devices are linearly connected to corresponding other devices through separate power supply lines. The distribution principle can also be combined within a single device.

[0013] For example, field devices and sensors require an operating voltage to function, which, with tolerance, is approximately 24V DC. Each device also requires a defined power source, i.e., a defined operating current, to draw power from the voltage source during operation.

[0014] One drawback of the current known solutions is that the power supply must be configured in advance based on existing power requirements. Therefore, users must know the power consumption of the operating equipment and design the power supply accordingly. The power supply must provide sufficient power to the equipment; that is, it must provide the total operating power, and the operating voltage of all equipment must be within the required tolerance range. However, within the equipment, the operating voltage will decrease depending on the current and line length. The operating current of the equipment is also related to the magnitude of the DC voltage supplied to the equipment.

[0015] The electrical connectors of this invention can be used, for example, in power supply for industrial production or logistics. Furthermore, various applications in automation and manufacturing technologies, as well as in the automotive and other technological fields, are also envisioned, where high safety standards and high reliability must be ensured.

[0016] Therefore, this type of electrical connector advantageously allows for the identification of weak points in power supply installations or power grids, especially before a fault occurs. Furthermore, it ensures particularly rapid diagnosis of damaged areas, for example, in the event of a cable break. It also allows for installation and immediate operation, ensuring that the system meets specific requirements. This, for example, can prevent downtime in warehouses or equipment. It also reduces the time required to locate faults when necessary. Additionally, it avoids the need for excessively large power supply systems.

[0017] The electrical connector can be configured in various ways. This is not limited to connectors that can be connected via a simple mating connection, but also includes other connectors. It can be configured such that the input-side contacts can connect, at least partially, to complementary mating elements via a mating process. In particular, the input-side contacts can be configured in various ways, for example, according to existing standards and specifications. For example, the connector can achieve threaded connections according to IP67, such as those with different M12 codes, 7 / 8" connections, or connections according to "M12 power" for high power requirements.

[0018] This type of electrical connector ensures power supply with the desired quality, particularly in terms of power requirements within the power grid. Here, for example, when the connector is used in a 12V environment, the achievable accuracy can be related to the corresponding infrastructure or technical conditions.

[0019] For example, for connectors, the input and / or output voltages can be determined, for instance, by measuring the current intensity, and the voltage difference between the connectors can be calculated from this. In this way, voltage drop can be detected in particular. Furthermore, cable temperature can be detected, which can, for example, indicate the resistance of the connection, such as temperature-dependent resistance.

[0020] In addition, cable status can be monitored, for example, to identify damaged cables.

[0021] Here, for example, the microcontroller and / or storage unit and / or power supply circuitry can be directly integrated into the connector. Furthermore, a voltage measurement system can be provided, for example, located on a power supply pin. Additionally, the communication interface can be implemented wired or wirelessly, for example via radio transmission, such as Bluetooth.

[0022] The contacts on at least one output side can be configured in different, known ways. Multiple output side contacts can be provided, and these contacts can also be configured differently; in particular, at least one output side contact can be used to establish an electrical connection for power transmission, and at least one output side contact is used to establish a data connection.

[0023] The contacts on at least one output side can be configured to connect a cable or wire; this connection can be permanent, such as for brazing or fusion welding, or a detachable connection can be established, for example by clamping, threading, or other methods known per se for connecting cables. In one configuration, a cable or wire is connected to the contacts on the output side. In particular, for a cable with multiple wires, one wire can be connected to each of the contacts on the multiple output sides of the electrical connector. In another embodiment, the contacts on the output side may include contact surfaces for establishing optical data connections, particularly for connecting optical wires.

[0024] The at least one input-side contact can be configured in different, known ways. Multiple input-side contacts can be provided, and these contacts can also be configured differently; in particular, at least one input-side contact can be used to establish an electrical connection for power transmission, and at least one input-side contact is used to establish a data connection.

[0025] The at least one input-side contact is specifically configured to connect to complementary connectors. The input-side contact may include, for example, pins or sockets, and furthermore, the contact may be configured as a contact surface. In another embodiment, the input-side contact may include a contact surface for establishing an optical data connection.

[0026] In another embodiment, the circuit is at least partially disposed outside the housing of the electrical connector.

[0027] Here, the detected operating parameters can be, for example, values ​​assigned to the connector and / or the cables or wires connected to the connector, and / or other connected units. These operating parameters are specifically selected to represent characteristics of power and / or data transmission.

[0028] Operating parameters can have different values, such as voltage and / or current. Additionally, other values ​​can be detected as operating parameters, such as capacitance, inductance, resistance, impedance, frequency, thermal characteristics, and / or other conductor characteristics.

[0029] The detection is performed, in particular, in a manner known per se, for example, by sensor elements that measure current intensity or voltage. For instance, the operating parameters can be detected between contacts on the input and output sides, for example, by a series connection or a series connection of sensor elements in a sensor device. Here, the measurement can be performed for connections existing between contacts on the output side. Furthermore, electrical operating parameters can also be detected between different connections, each existing between contacts on the input side assigned to that connection. Thus, for example, the potential difference between two electrical wires connected to a connector can be measured.

[0030] In one embodiment, the sensor device and the control device are mounted on a common carrier, and the carrier is configured as a circuit carrier injection-molded from plastic, on which metallic conductor lines are present. The carrier and / or at least a portion of the circuit can be fabricated by 3D printing or additive manufacturing. Alternatively or additionally, injection molding can be used to fabricate a housing and a carrier optionally connected to the housing.

[0031] In one embodiment, the control device is configured to generate stored data based on detected operating parameters, and to store the stored data via a storage device. The stored data may, for example, have a defined data format.

[0032] This allows for particularly flexible data provision and evaluation of historical data. In particular, it enables the determination of the evolution of detected operating parameters over time.

[0033] In particular, the storage device is integrated into the electrical connector, and the circuitry disposed, for example, in the housing includes the storage device.

[0034] Here, the output can be performed in different ways. For example, the output data can be generated and output automatically, for example, at regular intervals, such as by time interval or according to the number of times a unit starts running, or the output can be performed in response to a call, such as when a call signal is detected, for example, when an external unit receives a corresponding signal.

[0035] In another embodiment, the control device is configured to automatically and / or output the output data upon receiving a request signal.

[0036] Advantageously, this allows for flexible access to the detected data.

[0037] For example, the output can be performed at regular time intervals. Furthermore, the output can be automatically triggered by a determined event, exceeding / below a threshold of a detected operating parameter, or otherwise. Request signals can be generated and received by the control device in various ways, particularly via a communication interface. For example, request signals can be designed to be digital, but they can also include analog signals, such as operations on a switch or the receipt of determined analog data signals.

[0038] In another improvement, the detected or determined operating parameters include voltage, current intensity, field strength, resistance, impedance, inductance, capacitance, temperature, and / or air humidity.

[0039] Advantageously, this allows for the detection of particularly important parameters of the operation.

[0040] For example, the sensor device can be configured to detect temperature and air humidity.

[0041] For example, the detected electrical operating parameters may be values ​​assigned to the connector, and / or the cables or wires connected to the connector, and / or other connected units. These operating parameters are specifically selected to describe characteristics of power and / or data transmission.

[0042] The operating parameters can be different values, such as voltage and / or current. Furthermore, other values ​​can also be detected as operating parameters, such as capacitance, inductance, resistance, impedance, frequency, thermal characteristics, and / or other conductor characteristics. For example, the electric field strength can be detected using a Hall effect sensor.

[0043] Cables can be connected to the connectors, particularly to the contacts on the output side of the electrical connectors.

[0044] In one embodiment, a cable is connected to two electrical connectors of the present invention, the cable being connected in particular to a contact on the output side of the first connector at a first end and to a contact on the output side of the second connector at a second end.

[0045] When detecting electrical operating parameters, for example, the voltage difference between the connectors can be determined, particularly according to formula U. diff =U1-U2 calculates the voltage difference, U diff U1 and U2 represent the voltage difference, and U1 and U2 represent the voltage measured at the first or second connector.

[0046] When testing electrical operating parameters, for example, the resistance between the ends of the cable can be determined, particularly the resistance between the first and second connectors.

[0047] For example, this measurement can be used to identify broken wires and / or to identify short-term interruptions in cable conductivity, such as interruptions that occur due to poor contact.

[0048] In addition, the insulation resistance between the wires connected to the connector can be detected as an operating parameter.

[0049] Furthermore, the current intensity through the wires connected to the connector can be detected as an operating parameter.

[0050] For example, current can be measured indirectly by the electric or magnetic field surrounding a conductor. Field sensors, current sensors, Hall effect sensors, and / or other sensor circuits are used in particular here.

[0051] It can be configured that detected operating parameters, such as measured voltage or current intensity, and / or values ​​determined based on the operating parameters, are transmitted via wired or wireless communication through a communication interface. In this case, the output data is output and / or the output data can be acquired externally.

[0052] In one implementation, the output data can be output via a communication interface, either wired or wirelessly. Here, the communication interface may be configured as a radio interface or include a radio interface.

[0053] This makes it particularly easy to obtain the output.

[0054] Methods known per se, such as Bluetooth, 5G, RFID, near-field communication methods, and / or WLAN / LAN, can be used. For example, the communication interface may be included in a remote communication module. Furthermore, an antenna element may be provided for transmitting and / or receiving electromagnetic waves for data connection.

[0055] For wired outputs, known methods can be used, such as providing data via a power supply wire, in which case the voltage value is modulated to transmit the data.

[0056] In another embodiment, the circuit further includes a storage device configured to store detected operating parameters and / or output data; wherein the data stored by the storage device can be read out via a communication interface.

[0057] Advantageously, this makes it particularly easy to evaluate past data. In particular, there is no need for continuous output; stored data is only requested or output when evaluating a specific cause.

[0058] For example, the stored data can be determined based on operating parameters detected within a specific time interval. That is, the stored data may involve the values ​​of operating parameters detected within said time interval, and / or stored within that specific time interval. Furthermore, storage can be triggered by predetermined events, such as external control signals, malfunctions, exceeding or falling below limits, or specific changes in detected operating parameters over time. For instance, storage can be triggered when a detected operating parameter or its derived value changes rapidly or deteriorates.

[0059] Furthermore, the stored data is generated and stored according to the principle of a ring memory. It can be configured to always store the values ​​of detected operating data and / or values ​​determined based on the operating parameters within the elapsed time period, and then remove them. When specific events occur, such as external control signals, malfunctions, exceeding or falling below limits, or specific changes in detected operating parameters over time, the data stored in the ring memory can be accessed, and the evolution of the operating parameters over the specified time period can be evaluated.

[0060] The time interval here can be defined as the elapsed period of time; but it can also represent the occurrence of a specific number of predefined events, such as a switching process or similar events.

[0061] In another improved embodiment, a cable is also provided connected to the contacts on the at least one output side. Here, the cable has cable parameters, the values ​​of which are stored in a storage device. The cable parameters may include, for example, length, resistance, current intensity, maximum voltage and / or power, inductance, capacitance, heat value, material properties, or model number.

[0062] This advantageously provides data on the connected cables, which is typically constant and has been advantageously integrated into the manufacturing process, provided through simple measurement methods and / or after a single measurement. This allows for a more comprehensive evaluation of the detected operational data.

[0063] The cable can be constructed in different, known per se, ways. In particular, the cable is suitable for conducting or transmitting electrical power, current, voltage, signals, and / or optical signals. The cable can, in particular, have multiple conductors, which can be configured equivalently or for different transmission modes.

[0064] For example, the storage device can be used to store information about the connector and / or the connected cable.

[0065] For example, the conductor length of a pre-fabricated cable can be stored. In this case, the length of the cable is known, so this information can be directly provided to the storage device when manufacturing electrical connectors with cables.

[0066] For example, different production parameters and / or identification data can be stored via the connector and / or connecting cable. For example, model number can be stored.

[0067] For example, the resistance of the wires connected to the connector can be stored, in which case the resistance is measured at the manufacturer, particularly during manufacturing.

[0068] For example, when manufacturing a connector with a connecting cable, a calibration step can be performed, and a storage device can store calibration data; the calibration data can be values ​​of different parameters, which may be specific to the cable and / or connector and are related to the operation of the cable and / or connector and / or power supply unit.

[0069] For example, the storage device can store the insulation resistance between the individual wires of the cable connected to the connector, which in particular can be measured and stored in the storage device at the manufacturer's place of manufacture and / or at a later time.

[0070] For example, the storage device can store characteristic values ​​of the evolution of wire resistance with temperature.

[0071] Furthermore, the stored cable parameters can be configured such that they can determine other parameters. In this case, the other parameters do not need to be directly detected. For example, the thermal insulation value of the cable can be stored, and during operation, the cable's temperature or the amount of heat it releases can be determined. In this way, for example, the risk of cable overheating can be identified in a timely manner.

[0072] For the operation of cables and / or connectors, relationships between different cable parameters or between environmental parameters and cable parameters can be stored. For example, parameters relating to the current load capacity of connecting wires, particularly those related to temperature, can be stored in the storage device. For instance, data from characteristic curves can be stored, which allow for the determination of load capacity based on detected temperature, such as determining the maximum permissible values ​​for power, voltage, and / or current intensity.

[0073] For example, the thermal conductivity of the cable insulation structure connected to the connector can be stored in the storage device accordingly, and in particular, data on the correlation between the thermal conductivity and specific installation conditions can also be stored.

[0074] Furthermore, it is possible to subsequently store additional information, particularly cable parameters, in the connector's storage device. For example, control devices and communication interfaces can be configured to provide an operating interface through which additional information can be detected, for example, based on user input and / or signals received from external units.

[0075] Other stored information may relate to installation conditions, which may affect thermal conductivity. For example, thermal conductivity may depend on whether the cable is embedded in insulation or whether the surrounding materials are suitable for absorbing the radiated heat.

[0076] In addition, the additional information may relate to the ambient temperature, for example, when the ambient temperature can be determined to be a fixed value, such as in an air-conditioned room or a cold storage room.

[0077] Furthermore, the additional information may relate, for example, to individual limits for the current load, particularly in order to provide the conductor reserve available in use. Additionally, the additional information may also relate to electromagnetic compatibility parameters, such as information associated with the characteristics of the shielding structure.

[0078] Furthermore, the additional information may, for example, relate to individual limits on the voltage that can be applied to the conductors and / or cables. Additionally, the additional information may relate to other limits on the conductors and / or cables, such as current intensity.

[0079] In addition, the additional information may, for example, involve identification data of the connector and / or the connected cable, such as model or type name, serial number, item number, or similar information.

[0080] In addition, other data can be automatically detected and stored in a storage device via a control device, for example, through a connection to a database or a pre-defined data source.

[0081] In one embodiment, the circuit further includes a positioning device. The output data specifically includes positioning information detected by the positioning device. To achieve the connector's locatability, methods known per se can be used, such as 5G or GPS technology, or other methods.

[0082] Advantageously, this facilitates maintenance, as the source of fault reports or alarm reports can be easily identified when necessary.

[0083] The location information is used to determine the arrangement of connectors and / or cables connected to the connectors, particularly relative to an initial point, such as a central unit or voltage source. For example, in dense local 5G networks, location information is determined relative to the location of the transmitting station, and by means of methods such as propagation time and / or angle determination based on radio signals.

[0084] Here, the positioning information is associated with the electronic or communication unit of the connector; for example, the positioning information can be detected by an integrated positioning device, or in other embodiments, it can be provided in other ways, such as by inputting the positioning information during connector installation. For example, positioning information relative to one or more reference positions is determined and stored. Furthermore, the positioning information can be formed descriptively, such as "next to another element X," "in cabinet Y," or otherwise described with reference to other elements.

[0085] The location information can be used to identify, for example, the topology of the conductors, or the topology of the entire (voltage) supply network can be determined from the topology of individual conductors. For example, the power consumption at each node, particularly at a substation, due to connected equipment can be determined based on the measured current intensity and / or voltage difference.

[0086] For example, the electrical connector can be used for methods of condition detection or monitoring cable connections. Here, the cable connection can be configured to transmit data and / or electrical power.

[0087] Here, for example, feature values ​​can be calculated, and the existence of defined alarm conditions can be checked. Specifically, the detected operating parameters are compared with defined thresholds, and an alarm is output when the parameters exceed or fall below the thresholds.

[0088] Thresholds can be predefined to define alarm conditions. Alternatively, the thresholds can be determined dynamically, for example, based on detected operating parameters and / or environmental parameters, such as temperature, humidity, or requirements for connected devices.

[0089] Here, the processing of detected operating parameters and the detection of alarm conditions can be performed through the connector circuitry.

[0090] Alternatively or additionally, processing can be performed using an external storage and / or computing unit, in which case the presence of alarm conditions can be checked. Such an external storage and / or computing unit can be configured, for example, as a fieldbus device or a field control unit.

[0091] For example, it can identify when the detected current intensity suddenly decreases or when a voltage drop occurs on the connected wires. This indicates, for example, a failure in a downstream fieldbus device, sensor, or other connected device.

[0092] An assessment of the conductor's condition can be determined based on the temporal evolution of detected operating parameters. This includes, for example, assessing the detected conductor resistance, or detecting changes in cable characteristics caused by ongoing aging, mechanical damage, and / or heating or cooling of the cable, for example, upon contact with liquids such as rainwater.

[0093] An assessment of the conductor's condition can be determined based on the evolution of voltage drop over time. Changes in cable characteristics caused by aging, mechanical damage, or heating or cooling of the cable, for example, upon contact with liquids such as rainwater, can also be identified.

[0094] The electrical connector of this invention enables communication between itself and a connected device, such as a fieldbus device, communication unit (e.g., a converter), connected sensor, power supply, or other device. During communication, a data connection exists specifically between the connector and the device. Furthermore, during communication, a data connection is also established between the connector and an external unit, and / or data connections can be established between different accessed and / or connected units via the connector.

[0095] In one embodiment, for example, when the operation of a connected device causes an overload on the wires connected to the connector, a message can be output through the connector. At this time, the device can be shut down, particularly automatically via an integrated or external control device. Furthermore, the device can be configured to minimize its power consumption, for example by shutting down I / O, and to output a report on the fault condition that has occurred when outputting such a message about a dangerous overload.

[0096] In another example, a message about the cable's load capacity is transmitted to the power supply. The power supply can then reduce its output current, shut down for safety, or trigger an alarm or output an alarm message.

[0097] In addition, the current / voltage status can be displayed on the connector itself, for example, via LEDs and / or other display devices.

[0098] For example, a green LED indicates that the voltage and current intensity are within pre-defined limits. An orange or yellow LED can indicate a dangerous overload, overvoltage, or undervoltage. A red LED can indicate that the specified limits have been exceeded. Other forms of output can be configured in other examples.

[0099] In one implementation, a communication protocol is established through which multiple connectors communicate with each other; this communication can be performed directly or indirectly through a central unit, such as an external control unit, or components included in an external control unit. Here, for example, measured operating parameters can be compared between different cables, particularly for identifying the conductor topology. For example, the difference in measured current or current intensity can be determined. Next, the magnitude of power consumption at each node due to the connected equipment can be determined. This makes monitoring equipment and / or cables particularly simple and efficient.

[0100] In one implementation, an alarm report can be output when an emergency is detected, and the alarm report may include location information. Specifically, it may include location information detected by a positioning device of the connector.

[0101] In one implementation, it can be configured to identify induced interference in wires and / or connectors, particularly induced voltages, which are caused, for example, by external fields, and by, for example, by adjacent wires or motors.

[0102] In one implementation, a mechanism can be set to identify functional failures in connected devices through abnormal power consumption patterns. This could be, for example, identifying changes in the device's power consumption over time, such as abrupt changes, or exceeding or falling below predefined limits. Such identification may be advantageous, for example, for power-consuming devices that lack corresponding protection or diagnostic devices, in order to identify and / or diagnose mechanically obstructed motors or malfunctioning heating elements.

[0103] To evaluate the detected operating parameters, methods from the fields of machine learning or artificial intelligence can be employed. Specifically, this is used to identify anomalous patterns in power consumption. In this case, evaluation can be performed using an external unit. Machine learning methods can be trained based on historical values ​​of the detected operating parameters.

[0104] Furthermore, it can be configured to interrupt the wire when predefined conditions are met, such as exceeding or falling below predefined limits or when a sudden change in operating parameters is detected. The interruption of the wire can be implemented in a protective shutdown manner known per se, in which case, for example, the circuitry included in the electrical connector is interrupted and / or triggered. For this purpose, a switch can be provided, constructed in a known manner, for example, as a semiconductor device, and alternatively or additionally, an electrical fuse can be provided.

[0105] Furthermore, safety devices for electronic components can be incorporated into the connector, particularly for short-term power outages. For example, a buffer capacitor can be used for this purpose.

[0106] In addition, in particular for short-term power outages, a power supply protection device can be set for the electronic devices in the connector, for example, so that an alarm report can be generated and output when the power is interrupted.

[0107] The system includes a cable having a first cable end and a second cable end, the first and / or the second cable end being connected to a contact on the output side of an electrical connector according to this specification.

[0108] The system uses the electrical connector according to the invention, and therefore has the same advantages as the electrical connector.

[0109] Furthermore, it can be configured that the first cable end is connected to a first electrical connector according to this specification, and the second cable end is connected to a second electrical connector according to this specification. Furthermore, it can be configured that a data connection exists between the first and second electrical connectors, through which data can be sent and / or received, particularly detected operating parameters, by means of data detected and generated by the first and / or second connectors.

[0110] In a method for operating a system with an electrical connector, the connector has a sensor device for detecting electrical operating parameters, comparing the detected operating parameters with thresholds, and generating and outputting output data based on the comparison result. Specifically, the comparison can be performed by a control device included in the electrical connector.

[0111] The connector is constructed in particular according to this specification. Specifically, first and second connectors may be provided, which connect to a first or second end of the cable and are constructed according to this specification.

[0112] The generation and / or output of the output data can be triggered based on a control signal. This control signal can be received, for example, by an external unit.

[0113] The method is specifically designed for operating the device. Therefore, the method has the same advantages as the device according to the invention.

[0114] When comparing detected operating parameters with thresholds, it is particularly important to check whether a condition exists. The output data is generated based on whether and how the condition is met.

[0115] The threshold used for comparison can be predetermined as fixed or determined dynamically, for example, dynamically during the iterative implementation of the method.

[0116] In particular, when making comparisons, the values ​​of typical, time-related or predefined expected values ​​and / or previously detected operating parameters of the system can be considered as thresholds.

[0117] In addition, when comparing detected operating parameters, one or more thresholds may be considered and / or one or more operating parameters may be detected and considered during comparison.

[0118] The comparison between operating parameters and thresholds can be performed in different ways: the detected operating parameters can be directly compared with predefined fixed or dynamically determined thresholds; in this case, the output data is generated based on whether it exceeds or falls below the threshold.

[0119] Alternatively or additionally, the changes in the detected operating parameters over time and / or with another value can be determined and used in the comparison; the output data is then generated based on the progression of the changes. For example, the first, second, and / or third derivatives of the detected operating parameters with respect to time and / or with respect to another variable can be used for comparison to identify, for example, rapid or abrupt changes that may indicate damage, or to identify gradual changes, such as those occurring with wear or aging.

[0120] The method described above allows for monitoring, for example, the connections established via the connectors for power and / or data transmission. In particular, multiple connectors and the resulting power supply network can be configured according to power requirements, and / or abnormal conditions can be identified. For example, rapid changes in the electrical characteristics of connected cables and / or accessed devices can be detected based on detected operating parameters.

[0121] Furthermore, the comparison results can trigger response measures to abnormal situations, such as shutting down, controlling power consumption, outputting alarm signals, or controlling the shutdown of components in the power supply network.

[0123] refer to Figure 1 To illustrate one embodiment of the electrical connector.

[0124] In the first embodiment, the electrical connector 10 has a housing 12 in which input-side contacts 14, 16, 18 and output-side contacts 20, 22, 24 are disposed.

[0125] In addition, the connector 10 also includes a circuit 30, which in this embodiment is also disposed in the housing 12.

[0126] In addition, the connector 10 also includes a sensor device 32, a control device 34, a storage device 36, a positioning device 37, and a communication interface 38.

[0127] In other embodiments, additional means may be included, particularly some of these means 32, 34, 36, 37, 38 may be missing and / or some of these means may be combined in other ways.

[0128] In this embodiment, sensor device 32, control device 34, storage device 36, positioning device 37, and communication interface 28 are included in the circuit 30. In particular, these devices may be mounted on a single circuit board and / or on a common component.

[0129] In another embodiment, these devices 32, 34, 36, 37, and 38 are not or not fully included in the circuit 30. These devices may also be located at least partially outside the housing 12.

[0130] In this example, contacts 20, 22, and 24 on each output side are connected to one wire 42, 44, or 46 of a cable 40 connected to the connector 10, respectively. In this embodiment, the electrical wires 42, 44, and 46 are used to transmit data and / or electrical power. In this embodiment, one end 41 of the cable 40 is connected to the connector 10.

[0131] Contacts 20, 22, and 24 on the output side are connected to circuit 30. These connections are... Figure 1 The diagram is for illustrative purposes only. Other circuits and connections can also be configured, particularly parallel and / or series circuits.

[0132] Contacts 14, 16, and 18 on the input side are also connected to circuit 30. These connections are... Figure 1 The diagram is only schematic; other circuits and connections can also be set up here, especially parallel and / or series circuits.

[0133] The connector 12 is configured to establish a correspondence between the wires 42, 44, 46 and the contacts 14, 16, 18 on the input side in a manner known per se. For example, the cable 40 can be connected to a device (not shown) through the connector 10 and / or multiple cables 40 can be interconnected.

[0134] In this embodiment, wires 42, 4, 46 are configured to be conductive and configured to transmit electrical power and / or data signals.

[0135] In another embodiment, at least some of the wires 42, 44, 46 may be configured solely for transmitting electrical power or electrical data signals. Furthermore, at least one wire 42, 44, 46 may be configured for optical data transmission, particularly as an optical conductor or glass fiber.

[0136] In this embodiment, the storage device 36 includes a non-volatile data memory. The data memory can be controlled by the control device 34 to store data and / or retrieve stored data. Furthermore, data stored on the storage device 36 can also be processed and / or deleted.

[0137] In this embodiment, it is further configured that a data connection 52 with the external unit 50 is established at least temporarily through the communication interface 38. This connection can be established in different ways known per se, such as via Bluetooth, near field communication / RFID, G5 or other mobile radio networks, WLAN, or other standards, particularly via radio signal transmission.

[0138] In another embodiment, a wired data connection 52 can be established between the communication interface 38 and the external unit 50. In particular, the data connection 52 can also be configured to be established via at least one wire 42, 44, 46 connected to the contacts 20, 22, 24 on the output side; in particular, the signal used for data transmission can be superimposed on the current used for power transmission.

[0139] In this embodiment, the positioning device 37 is further configured to detect information regarding the positioning of the connector 10. This can be implemented in different ways, such as via GPS, 5G, or other methods. The detected positioning information regarding the connector 10 may relate to, for example, an absolute position within a global coordinate system, or the information may relate to a relative position relative to an initial position, such as a relative position relative to a central control unit.

[0140] In another embodiment, the connector 10 further includes an output unit (not shown). The output unit may be configured as a display unit and may include, for example, a display and / or a light-emitting element. For example, it may include a light-emitting diode (LED), the emitting state of which can be controlled by the control device 34. In particular, light parameters such as brightness, color temperature, or flicker frequency can be controlled.

[0141] refer to Figure 2To illustrate an embodiment of the system, we will take, in particular, the embodiment of the electrical connector described above as a starting point.

[0142] In this embodiment, the cable 40 is configured to connect to a first connector 10' at a first end 41' and to a second connector 10'' at a second end 41''. Each connector 10', 10'', and their connections to the cable 40 are substantially as described above. Figure 1 As described above. These two connectors 10' and 10'' can also establish data technology connections 51' and 52'' with the external unit 50.

[0143] refer to Figure 1 and Figure 2 To illustrate one embodiment of the method, see the above references. Figure 1 and Figure 2 The explanation is the starting point.

[0144] In this embodiment of the method, when using cable 40 to transmit electrical power and / or data, electrical operating parameters are detected by sensor device 32.

[0145] In this embodiment, the detected operating parameters include voltage, current intensity, resistance, impedance, inductance, capacitance, temperature, and / or air humidity.

[0146] In this embodiment, the detected electrical operating parameters include the voltage and current intensity transmitted through cable 40 or through the two conductors 42, 44, 46 of cable 40.

[0147] In this embodiment, the control device 34 generates output data based on the detected operating parameters. The output data is then output through the communication interface 38, where it is transmitted to the external unit 50 in this embodiment.

[0148] Here, in this embodiment, so-called "state detection" is performed through the output data, that is, monitoring the state of cable 40, its wires 42, 44, 46, connectors 10, 10', 10'' and / or the entire system. Therefore, the output data is generated in such a way that parameters related to power and / or data transmission of the system and / or its individual components can be continuously monitored.

[0149] In this embodiment, in particular, the monitored operating parameters are checked to see if they exceed or fall below predefined limits. If such an event, such as an unexpected voltage drop, is detected, an alarm signal is output and transmitted to an external unit 50. At this time, the external unit can generate a control signal to introduce protective measures, such as shutting down a unit that may be damaged due to the voltage drop.

[0150] Different events can be defined, and alarm or warning signals can be triggered when the events occur, and different measures can be triggered.

[0151] For example, a gradual or sudden change in conductor characteristics may be detected, such as when cable 40 is damaged, when a specific external condition occurs, such as when a specific temperature is present, or when changes occur due to aging.

[0152] In this embodiment, the control device 34 is configured to generate stored data based on detected operating parameters, and to store the stored data via the storage device 36. Here, the stored data is configured to store and retrieve the detected operating data within a specific time period. This allows for the reproduction and evaluation of the evolution of operating parameters over time, such as determining how quickly the operating parameters change and / or when / with what frequency certain events occur, such as deviations from a threshold.

[0153] In this embodiment, storage device 36 stores detected operational data and / or output data. The data stored by storage device 36 can be read out via communication interface 38.

[0154] In this embodiment, the output data is also output automatically, for example at regular intervals or after a defined event, and / or upon receiving a request signal, particularly by transmission to external unit 50. This request signal, in this embodiment, is generated by external unit 50 and transmitted to connector 10 via a data connection.

[0155] In this embodiment, the output data can be output wirelessly via communication interface 38. Alternatively or additionally, in another embodiment, wired output can be performed, for example, via wires 42, 44, 46 of a connected cable 40.

[0156] Furthermore, in this embodiment, the cable 40 also has cable parameters, and these cable parameters are stored in the storage device 36. For example, the length, resistance, current intensity, maximum voltage and / or power, inductance, capacitance, calorific value, material properties, and / or model of the cable 40 and / or individual conductors 42, 44, 46 can be stored in the storage device 36.

[0157] This facilitates the determination of other values ​​based on the detected operating parameters, such as the temperature rise of cable 40, and ensures that the temperature does not exceed or fall below the determined specific limit values.

[0158] For example, the cable parameters can be determined by measurements performed during the manufacture of the cable and / or connector. Furthermore, a calibration step can be included in which the cable parameters are stored in the storage device 36.

[0159] In the current embodiment, the cable parameters are stored in storage device 36 in a manner that is substantially unchangeable for the user.

[0160] In another embodiment, the cable parameters can be changed at least partially afterward. In this case, for example, control device 34 provides an operating interface that can be accessed via data connections 52', 52'', and the operating interface allows for corresponding input. Furthermore, an authentication step can be included to ensure that the user has permission to perform write operations on storage device 36.

[0161] In this implementation, the output data includes location information detected by the positioning device 37. In this example, the location information is formed such that cable 40 and / or connectors 10, 10', 10'' can be easily located, for example, so that repair can be performed, upon output of an alarm or warning signal, in the event of cable 40 failure, or for other reasons.
