    专利说明:

    The invention relates to a plug according to the preamble of claim 1.
    Plugs are known, which are intended to connect high power devices, such as chargers for electric vehicles, to a low voltage grid. Due to the increasing spread of electromobility and the need to charge electric vehicles at home by means of a connectable to the household network charger, there is an increasing demand for such plugs.
    Due to the high connection power for a low-voltage network, charging may generate heat on the plug. This heat development can be monitored by means of temperature sensors, so that in the event of excessive heat generation of the charging current can be reduced to prevent damage to the plug, which could lead to electrical accidents or fire. The integration of temperature sensors in a plug is connected here for safety reasons with high restrictions. On the one hand, it must be ensured that the circuit with the mains voltage and the sensor circuit, whose supply voltage makes up only a small fraction of the mains voltage, are electrically reliably separated from one another. This can be done for example by the use of electrically insulating shrink tubing, with which the sensor circuit is isolated from the circuit with the mains voltage. Furthermore, a good thermal contact between the contact pins and the temperature sensors is required so that a temperature rise can be detected quickly enough.
    The disadvantage of this is that such connectors are very expensive to manufacture, and many manufacturing steps are to be done manually. For example, the insulation of the sensor circuit with shrink tubing is very labor intensive and therefore very expensive in mass production. Furthermore, during production, it must be ensured that small defects can develop a great potential danger. For example, it must be ensured during production that, when the electrical conductors are connected to the contact pins, there are no individual strands which could come into contact with the sensor circuit or reduce breakdown voltages.
    The object of the invention is therefore a connector of the type mentioned / 24
    36858, with which the mentioned disadvantages can be avoided, with which reliable and electrically safe, the temperature of the plug can be monitored at high currents, and which can still be made easily and in large quantities.
    This is achieved by the features of claim 1 according to the invention.
    This results in the advantage that a critical heat development of the plug can be reliably measured, the plug provides high electrical safety with respect to the separation of the two circuits, but is still easy to produce in large quantities. Due to the partition, the circuits with the mains voltage and the supply voltage are reliably electrically isolated from each other over a large area, even if they are located close to each other in space. This eliminates the need for reliable isolation of the circuit of the temperature sensor, whereby it can be produced with less effort. The built-in form part with the partition wall and at least one receptacle, in which the temperature sensor is arranged, can in this case first be fitted and prefabricated separately from the support plate, and then connected to the support plate. This allows a high degree of automation in the production. Furthermore, the part of the plug with the support plate, pins and electrical lines can be made largely independent of the built-in form part with the temperature sensor, and must not be subsequently manipulated, making a production of a connector with temperature sensors quickly switched to a production of a connector without temperature sensors can be. The arrangement of the temperature sensor in the at least one receptacle of the built-in form part is a good thermal contact between the built-in form part with the partition and the temperature sensor given because the built-in form part through the partition has a large heat transfer area to the contact pins and the electrical conductors, making a total of good thermal connection of the temperature sensor is ensured. Due to the arrangement of the temperature sensor in the at least one receptacle, this is also reliably fixed in position.
    Furthermore, the invention relates to a method for producing a plug according to / 24
    36858 the preamble of claim 11.
    The object of the invention is therefore further to provide a method by which a plug can be made easily and in large quantities, which can reliably and electrically safely monitor the temperature of the plug at high currents.
    The advantages of the method of manufacturing a plug correspond to the advantages of the plug.
    The subclaims relate to further advantageous embodiments of the invention.
    It is hereby expressly referred to the wording of the claims, whereby the claims at this point are incorporated by reference into the description and are considered to be reproduced verbatim.

    1 to 13 show at least parts of preferred embodiments of a plug 1, comprising a support plate 2 and at least two attached to the support plate 2 contact pins 3, wherein the contact pins 3 each have a free end 4 and a terminal end 5, wherein electrical conductors 19 of a Cable 6 are connected to the terminal ends 5 of the contact pins 3.
    The plug 1 is particularly intended for use with a charger for charging an electric vehicle. Furthermore, a charger for charging an electric vehicle with the plug 1 is provided. The plug 1 is also advantageous for use with other devices, in particular those in which heat is expected at the plug 1.
    The plug 1 is in particular a plug-in device. Furthermore, the plug 1 is designed in particular as a mains plug for a low-voltage network of 110 V to 250 V. The plug 1 may in particular be a plug 1 for luminous flux, / 24
    36858 thus have only a single contact pin 3 for an outer conductor. The plug 1 may be in particular a 3-pin connector. Such connectors for luminous flux are designed for lower power than plug 1 for heavy current. Particularly preferably, the plug 1 may be a Schukostecker, or similar to the Schukostecker standardized plug, such as type B plug or type G. sockets for such connector 1 are essentially present in every household, so that the charger is almost everywhere pluggable.
    The plug 1 has a support plate 2, on which the contact pins 3 attached, in particular carried out. The support plate 2 may be made of an insulating material, in particular plastic. The free ends 4 of the contact pins 3 are intended to be inserted into a socket. Here, a first side of the support plate 2 facing the free ends 4. The connection ends 5 may be arranged on a, the first side of the support plate 2 facing away from the second side of the support plate 2 or within the support plate 2.
    The terminal ends 5 are connected to electrical conductors 19, which are brought together in a cable 6. The connection of the terminal ends 5 with electrical conductors 19 can be effected in particular via a crimp connection. Here, a first electrical conductor 19 may be formed as an outer conductor, and a second electrical conductor 19 as a neutral conductor. Furthermore, an electrical conductor 19 designed as a protective conductor can be connected to lateral contact surfaces 23.
    It is provided that a built-in form part 7 is fixed to the support plate 2 with a dividing wall 8, that the mounting form part 7 has at least one receptacle 9 on a side of the dividing wall 8 facing away from the contact pins 3, and that a temperature sensor 10 is provided in the at least one receptacle 9 is arranged.
    Since built-in mold part 7 is an electrically insulating part, preferably made of plastic, which is installed in the plug 1 by attaching to the support plate 2. The built-in form part 7 is particularly preferably formed in one piece, whereby its attachment to the support plate 2 is substantially simplified.
    The built-in molded part 7 has a partition wall 8, which has a first / 24
    36858
    Interior region of the plug 1 with the electrical conductors 19 of the contact pins 3, and a second inner region of the plug 1 with the temperature sensors 10 and the sensor lines 14 from each other. The partition wall 8 is in a fixed state of the built-in form part 7, in particular at the, the free ends 4 facing away from the first side of the support plate 2 to the support plate 2 and extending from the support plate 2 away.
    The built-in molded part furthermore has at least one receptacle 9, in which receptacle a temperature sensor 10 is arranged. The receptacle 9 is preferably formed directly on the partition 8. The receptacle 9 is furthermore preferably arranged on a region of the dividing wall 8 which is directly opposite a connection end 5. The receptacle 9 preferably has a profile which corresponds to a profile of the temperature sensor 10. Furthermore, the receptacle 9 can completely surround the temperature sensor 10, in particular at least annularly.
    The temperature sensor 10 is provided to measure a temperature within the plug 1, preferably at the terminal ends 5 of the contact pins 3. The temperature sensor 10 may particularly preferably be an NTC sensor, whereby alternatives such as a PTC sensor or other types of sensors would also be possible. Preferably, a separate temperature sensor 10 may be provided per contact pin 3. The temperature sensor 10 is connected to sensor lines 14, which in particular can also be removed via the cable 6. The sensor lines 14 may be connectable to a temperature control at another end of the cable 6. In particular, it can be provided that parts of the circuit of the temperature sensor 10 are only partially insulated up to a height of the partition wall 8, as a result of which this circuit is easier to produce.
    Furthermore, in a method for producing the plug 1, wherein at least two contact pins 3 are fastened to the support plate 2, the electrical conductors 19 of the cable 6 being connected to the connection ends 5 of the contact pins 3, it is provided that in the at least one receptacle 9 one
    Einbauformteils 7, a temperature sensor 10 is arranged, wherein the
    Built-in part 7 has a partition 8 and the at least one receptacle 9 is arranged on a, the contact pins 3 opposite side of the partition 8, / 24th
    36858
    Ί and that the built-in form part 6 is fixed to the support plate 2.
    This results in the advantage that a critical heat development of the plug 1 can be reliably measured, the plug 1 provides high electrical safety with respect to the separation of the two circuits, but is still easy to produce in large quantities. By the partition 8 in this case the circuits with the mains voltage and the supply voltage are reliable from each other over a large area electrically isolated, even if they are spatially close to each other. This eliminates the need for reliable isolation of the circuit of the temperature sensor 10, whereby it can be manufactured with less effort. The built-in form part 7 with the partition wall 8 and at least one receptacle 9, in which the temperature sensor 10 is arranged, can in this case first be fitted and prefabricated separately from the support plate 2, and then connected to the support plate 2. This allows a high degree of automation in the production. Furthermore, the part of the plug 1 with the support plate 2, pins 3 and electrical leads 19 can be made largely independent of the built-in form part 7 with the temperature sensor 10, and subsequently must not be manipulated, thereby producing a connector 1 with temperature sensors 10 quickly can be switched to a production of a connector 1 without temperature sensors 10. The arrangement of the temperature sensor 10 in the at least one receptacle 9 of the built-in form part 7 is a good thermal contact between the built-in form part 7 with the partition 8 and the temperature sensor 10 given because the built-in form part 7 through the partition 8, a large heat transfer area to the contact pins 3 and has the electrical conductors 19, whereby a total of good thermal connection of the temperature sensor 10 is ensured. Due to the arrangement of the temperature sensor 10 in the at least one receptacle 9, this is also reliably fixed in position.
    It can preferably be provided that the plug 1 has an injection-molded casing 21. In this case, the plug 1 is provided in a state shown in FIGS. 1 to 3 and 13 for producing the finished plug 1 with an injection-molded casing 21, which surrounds the support plate 2 and the built-in molded part Ί. 4 and 5, the finished connector 1 of the preferred / 24
    36858
    Embodiments shown. In particular, the built-in molded part 7 is completely surrounded by the injection-molded casing 21. The injection-molded casing 21 represents a widespread and cost-effective method for producing a housing for the plug 1. Alternatively, however, a housing could also be produced from a hard shell.
    In the width, the partition wall 8 preferably extends over the substantially entire width of the support plate. 2
    In the height, the partition wall 8 preferably extends beyond the height of the lateral contact surfaces 23.
    A thickness of the partition wall 8 may be at most 2 mm, preferably at most 1 mm, particularly preferably at most 0.5 mm.
    Particularly preferably, it can be provided that the temperature sensor 10 is in thermal contact by means of a press fit with an inner wall of the at least one receptacle 9. The interference fit ensures a good and consistent thermal contact between the temperature sensor 10 and the built-in molded part 7, whereby there is no risk of the thermal contact being unpredictably reduced by possible air inclusions. Furthermore, the production is particularly simple, since the temperature sensor 10 only needs to be pressed with a sufficient force into the at least one receptacle 9.
    In particular, provision may be made for an insertion opening 11 of the at least one receptacle 9 for the temperature sensor 10 to be arranged on a side of the fitting part 7 facing the support plate 2, and for the insertion opening 11 to be closed by the support plate 2. In the method, provision may be made for the temperature sensor 10 to be introduced through the insertion opening 11 into the at least one receptacle 9, and for the insertion opening 11 to be closed by the support plate 2 when the fitting part 6 is fastened to the support plate 2. With the attachment of the built-in form part 7 on the support plate 2, therefore, the insertion opening 11 is automatically closed for the temperature sensor 10, whereby it can no longer leave the receptacle 9.
    The temperature sensor 10 preferably has two parallel contact pins 13/24
    36858, with which the temperature sensor 10 can be connected to the sensor circuit.
    The contact pins 13 may in particular run parallel to the partition 8.
    Preferably, it may further be provided that at a side facing away from the insertion opening 11 of the at least one receptacle 9 outlets 12 for two electrical contact pins 13 of the temperature sensor 10 and a stop for the temperature sensor 10 are arranged. In particular, a separate outlet 12 can be provided per contact pin 13, whereby the area between the two outlets 12 is formed as a stop for the temperature sensor 10 in the at least one receptacle 9. As a result, the contact pins 13 at well-defined positions, which simplifies further connection of the contact pins 13 with the remaining circuit of the temperature sensor.
    In particular, it can be provided that an associated receptacle 9 with a temperature sensor 10 appears for each contact pin 3. In the case of two contact pins 3, therefore, two receptacles 9 each having a temperature sensor 10 can be provided. In Fig. 11, the preferred arrangement of the temperature sensor 10 is shown to the contact pins 3, wherein for the purpose of better visibility, the built-in form part 7 is hidden.
    FIG. 6 shows the built-in form part 7 of the preferred embodiment in a state in which the temperature sensors 10 are still arranged outside the recesses 9. In Fig. 7, the temperature sensors 10 are then disposed within the recesses.
    It can preferably be provided that a sensor neutral conductor 16 is connected to a conductor bracket 17, and that the conductor bracket 17 is electrically connected to at least two temperature sensors 10. The sensor neutral conductor 16 connects a zero potential with the temperature sensor 10. When the temperature sensor 10 is operated with direct current, the sensor neutral conductor 16 can be regarded as ground. The conductor bracket 17 may in particular be uninsulated, so that the sensor neutral conductor 16 can be easily connected to this. Due to the bow shape, the conductor bracket 17 on the attachments to the lateral / 24
    36858
    Contact surfaces 23 are passed.
    The conductor bow 17 can be produced in particular by angling and then connecting in each case one contact pin 13 of two temperature sensors 10. Alternatively, the conductor bracket 17 may be formed by an additional conductor connected to a respective contact pin 13 of at least two temperature sensors 10.
    In Figs. 8, 9 and 12, the built-in molded part 7 is shown in a state in which the conductor bracket 17 has been formed. In this state, the mounting mold part 7 is preferably attached to the support plate.
    It can preferably be provided that the built-in form part 7 is fastened to the support plate 2 by means of a clip connection 18.
    In particular, two side regions 22 on the dividing wall 8 can extend around the first inner region of the plug 1 with the electrical conductors 19 and the contact pins 3, wherein the dividing wall 8 with the two side regions 22 form a substantially U-shaped but edge-open demarcation. As a result, it can be prevented that a free strand of an electrical conductor 19 around the dividing wall 8 in the first inner region of the plug 1 with the
    Temperature sensors 10 protrudes. Furthermore, this makes the built-in molded part 7 more stable, and it reduces the risk that during the injection of the injection-molded casing 21, the built-in molded part 7 is displaced. Two clip connectors of the clip connection 18 can be arranged in particular at free ends of the side regions 22.
    Furthermore, clip connectors of the clip connection 18 can be integrally formed on projections formed on the recesses.
    Preferably, the built-in molded part 7 is open-edge relative to a first inner region of the plug 1 with the electrical conductors 19 of the contact pins 3, so that the built-in form part 7 can be attached to the support plate in a manufacturing state of the plug 1, when the electrical conductors 19 already with the contact pins. 3 are connected. As a result, the usual manufacturing steps for a plug 1 without temperature sensor 10 unchanged / 24
    36858 are retained.
    In particular, it may be provided that on the dividing wall 8 in the at least one receptacle 9, an extension 15 arranged between two sensor lines 14 connected to the temperature sensor 10 is formed. In particular, an extension 15 can be formed with each recording. The extension 15 may in particular extend from the receptacle 9 to an upper end of the partition 8. The extension 15 reliably separates the two contact pins 13 of a temperature sensor 10 from each other, so that there is no risk that during the injection of the injection-molded casing 21, a contact pin 13 is pressed against the other, thereby short-circuiting the temperature sensor 10. On the other hand, the extension 15 allows easy access to the contact pin 13 in the connection to the sensor lines 14 or the conductor bracket 17 during manufacture.
    It can preferably be provided that the temperature sensors 10 each have a separate power supply via a separate sensor line 14. As a result, it can be better recognized when a contact pin 3, for example due to an increased contact resistance, leads to a critical development of heat. Alternatively, the temperature sensors 10 may be connected in series or in parallel, and have a common sensor neutral conductor 16 and a common power supply.
    Preferably, it can be provided that a fixing the temperature sensor 10 in the at least one receptacle 9 spaced from the support plate 2 holds. Due to the spacing of the temperature sensor 10, the length of a creepage distance from the temperature sensor 10 to the contact pins 3 can be extended by the contact surface 23 between the built-in form part 7 and the support plate 2, whereby the breakdown voltage is increased. The fixation should further prevent the temperature sensor 10 from being pressed in the direction of the support plate 2 by the injection molding compound during the injection of the injection-molded casing 21.
    The fixation can particularly preferably be effected indirectly by at least one contact pin 13. As a result, the temperature sensor 10 is held by its contact pin 13 against the stop in the receptacle 9. The contact pin 13 can in this case be fixed in particular outside the receptacle 9.
    / 24
    36858
    In the first preferred embodiment in FIGS. 1 to 11, a fixing takes place in that the conductor bow 17 rests on the attachments on the lateral contact surfaces 23.
    Particularly preferably, it can be provided that the fixing takes place in that at least one of the outlets 12 of the at least one receptacle 9 projecting contact pin 13 or, the contact pin 13 extending conductor, after the outlet 12 to a molded-on part 7 on the formwork support 20th is angled. In one, the temperature sensor 10 from the outlets 12 pushing force of the contact pin 13 or, the contact pin 13 extending conductor is pressed against the support 20, whereby the temperature sensor 10 is reliably held in position. By integrally formed on the mounting member 7 pad 20, this is done independently of the actual design of the rest of the plug, whereby the fixation is reliable even with plug types without lateral contact surface 23. This is particularly advantageous in the formation of a conductor bow 17, since a tensile force is counteracted on a contact pin 13 in any direction by the two, applied to the attacks temperature sensor 10. Such a preferred embodiment is shown in FIGS. 12 and 13.
    The support 20 may in this case be part of a further, in particular parallel to the extension 15 extending, further extension.
    Furthermore, it can be provided that on the partition wall 8, in particular between the pads 20 arranged, Anlötauflage 24 is formed. Here, the solder joint between the conductor bracket 17 and the sensor neutral conductor 16 may be arranged on the Anlötauflage 24 formed as a projection, the Anlötauflage 24 ensures reliable positioning of the guide bracket 17 for soldering the sensor neutral conductor 16.
    In another, in the Fig. But not shown, preferred
    Embodiment, the fixation can take place in that at least one, from the outlets 12 of the at least one receptacle 9 projecting contact pin 13 is angled immediately after the outlet 12. The angled contact pin 13 can then be angled again S-shaped.
