Description
Technical Field
The present invention relates to a cable clamp and a system for monitoring a plug connector having such a cable clamp.
Background
In monitoring the plug connection, the electrical characteristic variables in the plug connector itself or in the vicinity of consumers or control devices connected to the plug connector should be measured as far as possible. Due to the small installation space available inside the plug connector, the integration of the sensor, the power supply unit for the sensor and the interface for controlling the sensor into the plug connector may be limited. Furthermore, the presence of temperature sources within the plug connector should be avoided as far as possible, since heat input may affect the structural integrity of the soldered connection or of the plug connector housing or other plastic parts.
Furthermore, the metal housing part of the plug connector may distort the measurement signal or prevent wireless communication with the sensor. It is also disadvantageous that the sensor system, which is installed fixedly in the plug connector, is not used to any great extent, since the measurement for diagnosis or maintenance must generally be carried out only in a punctiform manner.
Furthermore, it is not always clear which measurement variables are actually detected during operation to monitor the plug connector before the plug connector is fitted.
SUMMERY OF THE UTILITY MODEL
Against this background, the object of the present invention is to provide a cable clamp and a system for monitoring a plug connector which do not have the above-mentioned disadvantages or at least do so to a lesser extent and which enable a reliable, flexible and cost-effective monitoring of the plug connector in particular.
Correspondingly through according to the utility model discloses a cable clamp and according to the utility model discloses a system for monitoring plug connector solves above-mentioned technical problem. Other configurations of the present invention will be apparent from the following description.
According to a first aspect, the present invention relates to a cable clamp having: a housing configured for at least partially enclosing a cable or cables at a circumferential side; at least one securing device for releasably securing the housing to the at least one cable; a power supply unit configured to supply electric power to a sensor integrated into the cable clamp and/or a sensor separated from the cable clamp, and the like; a communication unit configured for transmitting sensor data to an evaluation and/or indication device, wherein the power supply unit and the communication unit are at least partially integrated into the housing.
The power supply unit may be used to supply electrical energy to a functional element, such as a sensor, a microcontroller, a memory unit, an interface or an indication element, which is at least partially integrated into the housing. Alternatively or additionally, the power supply unit can be used to supply electrical energy to an external sensor, microcontroller, memory unit, interface or indicator element separate from the cable clamp (e.g. integrated in the plug connector). For this purpose, the supply unit can supply a supply voltage of, for example, 2 to 8 volts, in particular 3 to 6 volts.
In particular, the housing can be fixed to the cable or cables in a form-fitting and/or force-fitting manner by means of a clamping connection. In this way, a releasable connection can be provided in a simple manner between the cable clamp and the cable or cables, so that the cable clamp can be used again, in particular in a spot-type manner for maintenance and/or diagnostic tasks.
The cable clamp may have one or more cylindrical recesses formed on the housing, which are configured for circumferentially enclosing one or more cables, respectively, and in particular flush with an outer mantle surface of the respective cable.
The power supply unit and the communication unit may be completely surrounded or encapsulated by the housing, so that only cable ends or plugs, for example for communication or power supply, protrude from the housing.
The housing may be at least partially formed of plastic or may be made entirely of plastic. The power supply unit and the communication unit may be arranged on a circuit board and cast in a plastic housing.
The evaluation and/or indication means may be, for example, a laptop, a desktop computer, a tablet computer, a smartphone or an analog or digital measuring device.
According to a further embodiment of the cable clamp, the housing has two half-shells which are connected to one another in an articulated manner by means of a hinge, wherein the fixing device is arranged on that side of the half-shells which faces away from the hinge. In a simple and cost-effective manner, a releasable cable clamp can thus be provided, which can be held or fixed to one or more cables by means of a clamping connection in a force-fitting and/or form-fitting manner.
It can be provided that the half-shells are connected to one another by means of a hinge in a releasable or exchangeable manner. In this case, the first half-shell can have the communication unit and the power supply unit as integral components, while the second half-shell has the sensor device and/or the measuring device arranged therein. The cable clamps can therefore each be equipped, if necessary, with the sensor means/measuring devices required for the respective application in that: a replaceable second half-shell with sensors for measuring environmental and/or electrical variables is combined with the first half-shell providing communication and power supply. The hinge can at the same time serve as an interface for power transmission and communication between the power supply unit and the communication unit and the sensor or sensors of the second half-shell.
A further embodiment of the cable clamp is characterized by a sensor interface for connecting the cable clamp to a sensor integrated into or fixed to the plug connector, wherein the interface enables the power supply to the sensor and/or the transmission of signals between the sensor and the communication unit. Accordingly, the cable clamp can be used as a means for transferring the device for operating the sensor from the plug connector to an external unit, i.e. the cable clamp, and in this way, on the one hand, a structural space inside the plug connector can be saved and, on the other hand, a more cost-effective plug connector can be realized. As long as the cable clamp is not connected to the sensor of the plug connector, the sensor of the plug connector accordingly does not function. In order to activate the sensor and to acquire measurement data, a cable clamp can be attached to the cable end associated with the plug connector and coupled to the sensor in order to activate the sensor.
The interfaces may for example be cable ends protruding from the housing, which are connected to the power supply unit and/or the communication unit. Alternatively or additionally, the sensor interface may be designed in the form of a socket or plug, which can be connected to the sensor of the plug connector with a complementary plug or a complementary socket.
The transfer of the device for operating the sensor out of the plug connector has the following advantages: the measurement signal detected by the sensor can be transmitted substantially without interference, wherein no additional temperature source is arranged within the plug connector.
Alternatively or additionally, the cable clamp can have an interface for connecting the cable clamp to a power supply unit integrated into the plug connector and/or a communication unit integrated into the plug connector. The power supply unit and/or the communication unit in the plug connector can be connected in this way to all sensors contained in the plug connector.
It can be provided that the communication unit has a module for wirelessly transmitting signals and/or data to the evaluation and/or indication device. For example, the communication unit may have a WLAN module, a bluetooth module, an NFC interface, an infrared interface, etc. in order to transmit signals or data wirelessly to the evaluation and/or indication means.
Alternatively or additionally, the communication unit may have a module for wired transmission of signals and/or data to the evaluation and/or indication device. This may be, for example, a conventional network socket, a USB interface (USB (1.0; 2.0; 3.0), mini-USB, micro-USB, USB-C), or the like.
The communication unit can be completely integrated into the housing, in particular cast into the housing.
The microcontroller, the capacitors, the antenna, etc., which are arranged on one or more circuit boards, can be cast into the plastic of the housing and can thus be substantially completely surrounded on the circumferential side by the plastic of the housing. The same applies to the power supply unit and/or any sensor arranged in the housing.
The cable clamp may have one or more sensors for detecting environmental and/or electrical characteristic variables. For example, the cable clamp may have one or more sensors for detecting ambient temperature or air humidity. Alternatively or additionally, the cable clamp can have sensors for detecting a characteristic variable of one or more guide cables which are partially or completely enclosed on the circumferential side by the cable clamp. In particular, one or more sensors of the cable clamp may be configured to detect amperage or voltage of one or more encapsulated wire sections.
Such a sensor can be partially or completely integrated into the housing, in particular cast in the plastic of the housing, so that the sensor is protected from the environment by the housing.
It may be provided that the cable clamp has a cooling device for actively and/or passively cooling the at least partially encapsulated cable or cables. It is to be understood that the functional unit, such as the communication unit, the power supply unit and any sensors accommodated in or at the cable clamp may likewise be actively and/or passively cooled by means of the cooling device.
The cooling device may have thermocouples, phase change materials, phase splitters, fins or other enlarged surfaces, in particular with a large mass.
The cable clamp may have a memory device for storing measurement data.
The cable clamp can have a control device and/or a data processing device for controlling a sensor integrated into the cable clamp or separated from the cable clamp.
Alternatively or additionally, the cable clamp may have one or more RFID tags for marking and identifying the cable clamp.
Further, alternatively or additionally, RFID technology may also be provided that wirelessly powers one or more external sensors integrated into or separate from the cable clamp.
Alternatively or additionally, the cable clamp may have a device for indicating the status.
The power supply unit may have a battery or a battery for self-contained power supply for the communication unit, the control device and/or the data processing device and/or the sensor. Alternatively or additionally, the power supply unit has one or more transformers, such as step-down regulators or the like. In particular, the power supply unit can have an output voltage of 2 to 8 volts, in particular 3 to 6 volts, for supplying the sensors, microcontrollers, etc.
According to a further embodiment, the cable clamp is of modular design and has two or more individual segments connected to one another, wherein at least one of the individual segments encloses one cable or a plurality of cables in each case.
The cable clamp can be of modular design and consist of a plurality of individual segments connected to one another, wherein each individual segment encloses one cable or a plurality of cables in each case. In this way, the cable clamp may be adapted for use with one or more cables.
According to a second aspect, the invention relates to a system for monitoring a plug connector, having a cable clamp according to the invention, wherein the cable clamp is fixed to at least one cable, and wherein the cable is accommodated in a connection opening of the plug connector on an end side.
The plug connection can be monitored by means of a cable clamp. Here, sensors integrated into the plug connector can be coupled to the cable clamp, controlled and/or evaluated for sensor data. Alternatively or additionally, sensors integrated into the cable clamp can be used to monitor the plug connection and/or to measure environmental variables. Thus, a plug connector can be provided cost-effectively in that: one or more sensors which are subsequently or already installed in the plug connector at the time of factory production need not be equipped with corresponding interfaces, such as power supply and communication.
