Definitions
- the invention relates to a connector part for mechanical and electrical connection to a mating connector part, in particular a motor vehicle charging socket for coupling to a charging plug as part of an electrical charging infrastructure for electric or hybrid motor vehicles, or vice versa, with a housing and at least one electrical contact element arranged in the housing , and with a temperature monitoring device with at least one flat carrier element and at least one temperature sensor arranged thereon for the contact element, wherein the carrier element can be thermally coupled to the contact element using at least one spring element.
- the connector part is generally a charging socket in a motor vehicle, which can be coupled to an associated charging plug that is present, for example, on an electric charging station.
- the charging plug (and also the charging socket) is part of an electrical charging infrastructure that can be used to charge the rechargeable energy storage devices or accumulators of electric or hybrid motor vehicles.
- the connector part on the motor vehicle can also be a charging plug instead of a charging socket.
- the charging station is equipped with an associated charging socket.
- the electric or hybrid motor vehicle has a charging socket with several electrical contact elements arranged in the housing, into which the charging plug connected to the charging station is inserted for charging the motor vehicle in question.
- the temperature monitoring device has a support element which extends flatly along a plane and on which the sensor device or the temperature sensor is arranged.
- the carrier element is equipped with two clip arms, via which the carrier element is clipped onto the contact element to be monitored with regard to the temperature.
- EP 3 286 804 B1 involves a connector part, which is again equipped with a carrier element. With the help of the carrier element, heating on the at least one contact element is detected. For this purpose, the contact element extends through at least one opening in the carrier element.
- the state of the art has fundamentally proven itself when it comes to detecting and evaluating any heating of the contact element of the connector part using the temperature monitoring device.
- the temperature monitoring device is typically connected to a control unit, for example to ensure rapid shutdown in the event of overheating. This prevents any damage to the connector part and in particular to the associated housing, which is usually made of plastic.
- the known embodiments of the carrier element generally require a special design with regard to the contact element to be monitored in terms of temperature.
- Such clips must be adapted to the geometry of the contact element and can often only be connected to the electrical contact element in a specific assembly position.
- the invention as a whole aims to provide a remedy here.
- the invention is based on the technical problem of further developing a connector part of the structure described above in such a way that a flexible attachment of the temperature monitoring device to the electrical contact element to be monitored is possible while taking into account simple assembly.
- a generic connector part for mechanical and electrical connection to a mating connector part is characterized in the context of the invention in that the carrier element is arranged tangentially on the (cylindrical) contact element in a front view of the contact element.
- the carrier element is not connected, for example, directly to the contact element in order to provide the required thermal coupling and thus temperature monitoring, as is the case in the prior art with the clips according to EP 3 616 270 B1.
- the invention relies on a contacting contact of the carrier element on the cylindrical contact element in such a way that the carrier element is arranged tangentially on the cylindrical contact element or the carrier element touches the cylindrical contact element tangentially.
- the carrier element and with it the temperature sensor arranged on the carrier element can be flexibly attached to the cylindrical contact element.
- the design according to the invention expressly does not require a specific adaptation of the carrier element to the geometry of the cylindrical contact element - in contrast to the prior art.
- the diameter of the cylindrical contact element plays practically no role for the tangential contact of the carrier element.
- the contact element is cylindrical at least in the contact area with the carrier element, so that the carrier element can be arranged tangentially on the cylindrical contact element or the cylindrical area of the contact element. This gives the contact element a variety of degrees of freedom in its implementation. The same applies to the connector part as such and the associated housing, which the prior art cannot provide.
- the contact element has an insulating collar on the housing side with an insertion opening for the carrier element.
- the invention is based on the knowledge that a high-voltage direct voltage is present on the contact element or the usually two contact elements provided at this point.
- the contact element in question is equipped with the insulating collar on the housing side, ie inside the housing usually up to a connection area of the contact element.
- the contact element is a contact socket because the plug connector part is usually designed as a charging socket on the vehicle side.
- the insulating collar now ensures that the contact element or the contact socket is covered practically over the entire surface with the insulating collar except for the insertion opening for the carrier element, so that only a contact plug can be inserted into the contact socket as part of the charging plug and ensures the required electrical contact. Nevertheless, the support element can be easily assembled. All that is required is for the carrier element to pass through the insertion opening in the insulating collar and in this way to be applied tangentially to the contact element or its cylindrical region.
- the at least one spring element or, as a rule, the several spring elements ensure that the carrier element is positioned accordingly and is held in contact with the cylindrical contact element inside the insertion opening with the required force.
- the insulating collar generally represents a component of the housing and, like this, may be made of plastic, for example defining a one-piece plastic injection-molded part together with the housing.
- the insulating collar can also be provided separately from the housing.
- the contact element can be received by the insulating collar and the assembly assembly formed in this way can be installed in the housing by, for example, snaps.
- the size of the insertion opening is usually adapted to the carrier element or to the temperature sensor. This means that the size of the insertion opening typically corresponds to the external dimensions of the carrier element or the temperature sensor, so that no uncovered areas of the contact element are observed when the carrier element is installed in the insertion opening.
- the carrier element has a simultaneously heat-conducting and electrically insulating covering also contributes to this, so that the contact element is covered in an electrically insulating manner overall by means of the insulating collar and by the carrier element, which is also equipped with the insulating covering.
- the carrier element is typically a sensor board with conductor tracks for the electrical transmission of sensor signals.
- a circuit board made of an electrically non-conductive carrier material, such as plastic, is usually used, which is equipped with applied or inserted conductor tracks. Signals from the temperature sensor can be transmitted via the conductor tracks, for example, to a control unit connected to the carrier element via a supply line.
- the temperature sensor is typically a semiconductor sensor or a resistance sensor, which can, for example, have a positive temperature coefficient in the sense of a PTC resistor. With such temperature sensors, the resistance value increases as the temperature increases. Colloquially, these temperature sensors are also referred to as PTC thermistor and can be made, for example, from a ceramic material as so-called ceramic PTC thermistor. In addition, it is also conceivable to use electrical resistors with negative temperature coefficients, so-called NTC resistors, as temperature sensors. In this case, the resistance of the relevant temperature sensor decreases as the temperature increases. As a rule, the temperature sensor is arranged at the end of the carrier element on its top or bottom side. The carrier element itself is designed as a rectangular strip.
- the temperature sensor By attaching the temperature sensor at the end with reference to the rectangular strip, the temperature sensor can be placed in such a way that it comes into direct thermal contact with the cylindrical contact element or the cylindrical region of the contact element with the carrier element arranged tangentially to the contact element. In principle, however, it is also possible for the temperature sensor not to be located at the end, but rather in the middle of the carrier element.
- the carrier element may be equipped with a metal core, with the help of which heat is conducted from the contact surface of the carrier element with the contact element to the temperature sensor.
- the carrier element is designed, for example, as a so-called metal core printed circuit board, as described in detail in DE 39 35 680 A1.
- a metal plate is covered with plastic on the inside and additional conductor tracks can be applied, for example photolithographically, as described in detail in the aforementioned prior art.
- the sensor board or printed circuit board made of plastic with applied or embedded conductor tracks and without an additional metal core is used as a support element. This is because the temperature sensor located on the carrier element or the circuit board is generally arranged on the contact surface of the carrier element with the contact element, so that the heat flow emanating from the contact element hits the temperature sensor directly and almost without delay.
- the heat flow emanating from the contact element must first pass through the envelope that is generally provided and encloses the carrier element, which according to the invention is designed to be both heat-conducting and electrically insulating.
- the covering as a whole is designed so that it covers the sensor board or the circuit board and the Temperature sensor together encloses.
- the covering is typically a plastic covering.
- the covering usually uses a compound, which is initially a thermoplastic such as PA (polyamide), PBT (polybutylene terephthalate), PP (polypropylene), PPS (polyphenylene sulfide) or comparable thermoplastics.
- a thermoplastic such as PA (polyamide), PBT (polybutylene terephthalate), PP (polypropylene), PPS (polyphenylene sulfide) or comparable thermoplastics.
- PA polyamide
- PBT polybutylene terephthalate
- PP polypropylene
- PPS polyphenylene sulfide
- comparable thermoplastics are particularly easy to process by injection molding.
- a filler is added to the plastic in question or the plastic compound as a plastic coating.
- Graphite, carbon fibers or ceramics are recommended as suitable fillers.
- thermosets or thermoplastics that are equipped with electrically insulating, thermally conductive fillers are advantageously used at this point.
- aluminum compounds or boron compounds preferably aluminum oxide or boron nitride, have proven to be particularly suitable.
- the grammage of these electrically insulating and thermally conductive fillers in the plastic can be up to 50% by weight and more. Thermal conductivities of more than 1 W/(m ⁇ K) up to 25 W/(m ⁇ K) can be achieved. Further details with regard to such plastics can be found in the prior art according to DE 102007 037 316 A1, which can be cited as a reference here. Similar information can be found in DE 10 2013 208 605 A1.
- the invention also recommends that the casing for the carrier element including the temperature sensor typically has a material thickness of less than 1 mm, in particular 0.5 mm and less. This ensures very rapid heat transfer from the contact element to the temperature sensor, so that any overheating at this point can be detected immediately and, for example, result in a power shutdown.
- the invention recommends a special design of the carrier element, namely one in which the carrier element is equipped with two opposing temperature sensors. In this case, for example, two contact elements for a DC charging process can be temperature monitored simultaneously with a (single) carrier element. It goes without saying that by using the two opposite temperature sensors, the two contact elements can be monitored separately from one another for possible overheating.
- the control unit supplied with the sensor signals to mean that a switch-off or a current reduction takes place.
- the two opposite temperature sensors are again arranged in the area of the contact surface of the carrier element with the associated contact element in order to be able to realize and implement a temperature measurement that is as delay-free as possible.
- the design is usually such that the conductor track or the several conductor tracks define one or more contact areas as components of the carrier element or the sensor board or circuit board implemented at this point.
- the sensor signals can now reach the control unit particularly advantageously via these contact areas and the spring elements that generally enclose the contact areas at least on one side. It is understood that the contact areas in question are not covered by the covering of the sensor board including the temperature sensor, so that when the carrier element is mounted, the spring elements can directly electrically contact the contact areas in question.
- the spring elements take on a dual function, namely in such a way that, on the one hand, the carrier element in question is held in tangential contact with the contact element to be monitored.
- the spring elements also function as electrical contacts, namely in order to be able to forward the sensor signals from the temperature sensor attached to or on the carrier element to the control unit.
- additional contact areas to be implemented at this point, which do not necessarily serve to transport the sensor signals from the temperature sensor.
- a connector part and in particular a vehicle-side charging socket with a temperature monitoring device is made available and realized, in which the temperature monitoring device can be particularly flexibly adapted to different installation situations and designs of the relevant charging socket.
- the temperature monitoring device uses at least one flat support element, which is arranged tangentially on the cylindrical contact element for this purpose. This means that special fastenings on the contact element or specific mounting directions are not required, which explains the particular flexibility. This is where the main advantages can be seen.

- Fig. 2 shows the corresponding rear view of Fig. 1,
- Fig. 3 shows the object according to Fig. 2 enlarged in detail
- Figures 4A to 4C show the assembly of an alternatively used support element as a temperature monitoring device.
- the figures show a connector part for mechanical and electrical connection to a mating connector part.
- the connector part according to the exemplary embodiment in FIGS. 1 and 2 is a charging socket 1 on the motor vehicle side.
- the charging socket 1 is set up for coupling with a charging plug, which is not shown in detail and represents part of an electrical charging infrastructure for electric or hybrid motor vehicles.
- the charging socket 1 is equipped with a housing 2 made of plastic and at least one electrical contact element 3 arranged in the housing 2.
- a housing 2 made of plastic
- at least one electrical contact element 3 arranged in the housing 2.
- the additional electrical contact elements 4 provided are, in contrast, required for an AC charging process and will not be discussed in more detail below.
- the two contact elements 3 are equipped with a temperature monitoring device 5, 6.
- the temperature monitoring device 5, 6 has at least one flat support element 5 and at least one temperature sensor 6 arranged thereon for the contact element 3.
- the carrier element 5 is flat and designed as a rectangular strip or as a rectangular element. It is also clear that the temperature sensor 6 is arranged on a surface of the carrier element 5, namely at the end of the carrier element 5 in the area of a contact surface 7 with the contact element 3.
- the carrier element 5 is held with the help of several spring elements 8 and is achieved in this way that the carrier element 5 is thermally coupled to the contact element 3.
- the respective spring elements 8 are U-shaped springs, which surround the rectangular carrier element 5 on the edge.
- the individual spring elements 8 not only serve to hold the support element 5, but are also connected to electrical lines 9, which are only indicated in FIG. 3 and which in turn are connected to a control unit 10.
- the carrier element 5 is arranged tangentially on the contact element 3, namely in a front view of the contact element 3.
- the contact element 3 is cylindrical at least in the area of the contact surface 7.
- the contact element 3 is enclosed on the housing side with an insulating collar 11, which has an insertion opening 12 for the carrier element 5 or the temperature sensor 6 engaging in the insertion opening 12 on the carrier element 5.
- the insulating collar 11 can also be made in one piece with the housing 1 from plastic.
- the insulating collar 11 and the contact element 3 can also represent a pre-assembled assembly assembly 3, 11, which is connected to the rest of the housing 1, for example in a latching manner. However, this is not shown in detail.
- the size of the insertion opening 12 is adapted to the carrier element 5 or the temperature sensor 6 carried by the carrier element 5.
- the carrier element 5 is a sensor board or circuit board that is equipped with conductor tracks for the electrical transmission of sensor signals from the temperature sensor 6.
- the conductor tracks open into contact areas 13, which can be seen in particular in FIG.
- the spring elements 8 encompass the carrier element 5 in these contact areas 13, so that in this way not only the carrier element 5 is held in tangential contact with the relevant contact element 3, but at the same time the sensor signals emitted by the temperature sensor 6 are transmitted the spring elements 8 and the supply lines 9 can be transmitted to the control unit 10.
- the carrier element 5 and the temperature sensor 6 are equipped overall with a casing 14 that is both heat-conducting and electrically insulating.
- Envelope 14 is designed in such a way that only the previously mentioned contact areas 13 are left out. That is, the casing 14 encloses the sensor board or printed circuit board and thus the carrier element 5 and the temperature sensor 6 together.
- the casing 14 is a plastic casing that is applied by overmolding the carrier element 5 including the temperature sensor 6.
- the invention relies on a thermoplastic material, as has already been described in the introduction to the description.
- the plastic is a plastic compound with added fillers.
- the fillers used are those which simultaneously ensure good heat conduction and electrical insulation of the thermoplastic in question, for example in the form of aluminum oxide or boron nitride, as already described in the introduction.
- the covering 14 made of plastic can still be processed by injection molding and at the same time it is ensured that the covering 14 practically does not hinder the heat conduction from the contact element 3 to the temperature sensor 6 in the area of the contact surface 7. Nevertheless, the casing 14 provides the necessary electrical insulation in this area, so that any problems are not observed at this point.
- the casing 14 has a material thickness that is generally less than 1 mm and in particular 0.5 mm and less.
- a heat flow emanating from the contact element 3 can pass through the casing 14 immediately and in a short time and pass through the temperature sensor 6 in the area of the contact surface 7 almost without delay to reach.
- any overheating of the contact element 3 is immediately detected using the temperature sensor 6 and reported to the control unit 10 as described.
- the control unit 10 can then, for example, reduce the charging current at the contact elements 3 or even switch it off completely.
