Description

The invention relates to a high-voltage connector safety flap device for an electric high-voltage connector, in particular a high-voltage charging connector for a vehicle having an electric traction motor or a charging station. The invention further relates to an electrical high-voltage connector, in particular a high-voltage charging connector, and an electrical high-voltage entity, in each case in particular for a vehicle having an electric traction motor or a charging station.In the electrical field (electrical, electrical technology, electrical energy technology, etc.), a large number of high-voltage electrical connectors are known. These serve to transmit electrical voltages in the high-voltage range (high voltages: alternating voltages above 24 V to above 1 kV, direct voltages above 48 V to above 1.5 kV), electrical currents in the high-current range (high currents above 25 A to above 1 kA) and / or electrical powers in the high-power range (high powers from 20 kW to above 350 kW). In this case, the high-voltage connectors must ensure a satisfactory transmission for a short term and / or permanently for supplying and / or distributing electrical energy in cold, warm, possibly hot, contaminated, moist and / or chemically aggressive environments.Due to a wide range of applications, a large number of such high-voltage connectors are known in the automotive sector and in the non-automotive sector apart from ground-bound energy technology and analogues thereto. In the automotive sector, such a high-voltage connector is suitable, for example, for electrically connecting a high-voltage and / or high-current line to a corresponding electrical high-voltage entity or vice versa, for connecting electrical high-voltage and / or high-current lines, or for other electromechanical high-voltage and / or high-current contacting.High costs for fossil fuels and efforts to reduce environmental loads necessitate hybrid or electric vehicles, for example, in the automotive sector. One aspect of these vehicles is the handling of high electrical charging and operating voltages and high electrical charging and operating currents, wherein relevant components of the vehicles must be designed accordingly. This relates in particular to high-voltage and / or high-current lines (e.g. stranded lines, busbars, busbars, etc.) and to the relevant high-voltage and / or high-current terminals (e.g. connecting pieces, flat contacts, busbars, busbars, etc.) and therefore also to the high-voltage connectors.If a high-voltage connector is located on a high-voltage cable, this is also referred to as a flying (plug-in) connector or a coupling. If a high-voltage connector is located on / in an electrical high-voltage entity (cf. below), for example a section of a housing thereof, this is also referred to as a connector device, such as, for example, an (installation / attachment) connector.Efforts are constantly being made to improve high-voltage electrical connectors. In this case, the coming generation of electromobility is distinguished in particular by more rapid and convenient charging methods for fully electric and hybrid road vehicles and commercial vehicles. In this case, high-voltage charging connectors require protective flaps in order to prevent contact of current-carrying parts of the high-voltage charging connectors. - It is an object of the invention to specify a protective flap for a high-voltage connector, in particular a high-voltage charging connector for a vehicle having an electric traction motor or a charging station.The object of the invention is achieved by means of a high-voltage connector safety flap device (in the following description only referred to as "safety flap device") for an electrical high-voltage connector, in particular a high-voltage charging connector; by means of an electrical high-voltage connector, in particular a high-voltage charging connector; and by means of an electrical high-voltage entity; in each case in particular for a vehicle having an electric traction motor or a charging station. - Advantageous developments, additional features and / or advantages of the invention result from the dependent claims and the following description.The protective flap device according to the invention comprises a holder, an actuator and a protective flap, wherein the protective flap is configured to be pivotable between a closed position and an open position of the protective flap device, on the holder for opening and closing a plug face of the high-voltage connector, and the protective flap device is configured such that the protective flap is pivotable electromechanicalally by the actuator as intended on the one hand, and preferably further the protective flap can alternatively be pivoted manually as intended on the other hand. - I.e. the protective flap is actuatable both electromechanically and manually in particular independently of one another.The holder can be mounted on / in a high-voltage connector or a part of the high-voltage connector, e.g. a section of its connector housing. Such a connector housing can be formed, for example, as an essential connector housing, a partial housing, an outer or inner housing, a housing skirt, a housing section, a housing region, etc. of the high-voltage connector. - The protective flap is formed in particular in the shape of a lid. - The plug face can be formed as the single plug face or also a plug face of a plurality of, in particular two, plug faces of the high-voltage connector. In the second case, the high-voltage connector can be designed as a CCS high-voltage connector (CCS: combined charging system), wherein the protective flap device serves for opening and closing, in particular, the plug face with the DC poles.For the electromechanical pivoting of the protective flap, the actuator can act translationally or rotationally on the protective flap. - For the manual pivoting of the protective flap, a coupling can be configured in a force flow between the actuator and the protective flap, by means of which coupling the protective flap can be decoupled from a holding force of the actuator. That is, the clutch is configured as an actuator disconnect clutch and may be further configured as a slip clutch, lock-up clutch, release clutch, disconnect clutch, disconnect clutch, short circuit clutch, etc. In this specification, where appropriate, the term 'force' is intended to include the term 'torque' analogous thereto.The protective flap can be pivotable about a pivot axis. In this case, the protective flap device or the protective flap can have a radial lever with respect to the pivot axis, on which the actuator acts and via which the protective flap can be pivoted. Furthermore, the radial lever of the protective flap device or of the protective flap, and a cover plane of the protective flap can be configured at an angle of approximately: 0°, 15°, 30°, 45°, 60°, 75°, 90°, 105°, 120°, 135°, 150°, 165° or 180° with respect to one another. Preferably, the radial lever, i.e. a radial extension of the radial lever, and the cover plane, i.e. a radial extension of the cover plane, are substantially radially opposite one another with respect to the pivot axis, wherein an angle deviating therefrom (180°) by about: 10°, 20°, 30° or 40° can be configured.The actuator for the electromechanical pivoting of the protective flap can be configured to be movable back and forth on / in the holder in a substantially translatory manner. In this case, the actuator is guided supported on / in the holder, for example. Preferably, the holder guides the actuator on two mutually opposite sides, for example each by means of a protrusion which is slidable in a groove. In this case, the groove can be configured in the holder / actuator and the projection can be configured in the actuator / holder. The projection is in particular an elongate projection and is preferably only slightly shorter (stroke of the actuator, tolerance compensation, safety) than the groove.The actuator can have an actuating device, by means of which a pivoting device of the protective flap device or of the protective flap can be moved about the pivot axis. When the pivoting device is actuated by means of the actuating device, the pivoting device can be moved parallel with respect to the pivot axis. A circumferential movement angle of the pivot device with respect to the pivot axis is preferably at least about: 75°, 90°, 105°, 120°, 135°, 150°, 165° or 180°. The actuating device of the actuator can be designed in particular as an actuating recess and the pivoting device of the protective flap device or of the protective flap can be designed in particular as a pin with a preferably round, in particular circular diameter.A bearing between the actuating device and the pivoting device can translate a translatory movement of the actuator into a rotatory movement of the pivoting device with respect to the pivot axis. In this case, the pivoting device can preferably move both translationally and rotationally with respect to the actuating device or the pivoting device in the actuating device (cf. below). The bearing between the actuating device and the pivoting device can be configured as a slide bearing. The slide bearing is configured both as a radial slide bearing and as an axial slide bearing, wherein this radial axial slide bearing is essentially simultaneously subjected to both radial and axial stress during pivoting of the protective flap.The actuator with its actuating device can be designed substantially as a claw in the region of the pivot device. An extension of the claw in the direction of the pivot axis is preferably at least twice a diameter of the pivot device. The actuating recess forms the opening of the claw. Here, it is preferable that, when viewed in six sides, the claw is open in three sides (front and both sides) and closed in three sides (back and top and bottom) (see, for example, FIGS. 2, 6, and 7 ).The protective flap device can be designed in such a way that during the electromechanical pivoting of the protective flap, the entire coupling also pivots. Furthermore, the clutch can be held closed in a force-fit and / or form-fit manner in the unloaded state. In addition, the coupling can be used to manually pivot the protective flap. That is, by means of a manual pivoting movement, the protective flap can be decoupled from the holding force of the actuator by means of the coupling. Furthermore, the clutch can permit the manual pivoting of the protective flap substantially independently of a position of the actuator.The clutch can comprise a clutch assembly, by means of which a force flow between the actuator and the protective flap can be set up on the one hand and interrupted on the other hand. In a rest state of the clutch assembly, the force flow between the actuator and the protective flap can be configured. In the case of electromechanical pivoting of the protective flap, the force flow between the actuator and the protective flap can be set up. And, in the case of manual pivoting of the protective flap, the force flow between the actuator and the protective flap can be interrupted.The coupling assembly can be mounted on / in the holder so as to be pivotable or rotatable about the pivot axis, wherein the coupling assembly is preferably received on / in the holder by means of a coupling axis. In this case, a pivotability of the coupling assembly can be limited to below approximately: 360°, 270°, 180°, 150°, 120°, 105°. A rotation capability can naturally be over 360° and comprise no or a rotation capability of the clutch assembly. The clutch axle is preferably designed as an inner pivot bearing part and does not transmit any substantial torques; the substantial torques transmit the clutch assembly seated on the clutch axle. The coupling axle merely holds the coupling assembly and optionally the protective flap on / in the holder.Furthermore, the clutch assembly can be accommodated on the clutch axis such that it can be moved back and forth in one or both axial directions (play). That is to say, the clutch assembly is pushed onto the clutch axis, wherein an at least slight radial clearance is preferably set up between the clutch axis and the clutch assembly. Furthermore, the clutch assembly can be designed to be elastic or springable in the axial direction of the pivot axis. In addition, the clutch assembly can be drum-shaped or box-shaped.The coupling assembly may comprise two thrust pieces movable relative to each other. The pressure pieces can be configured in the clutch assembly mechanically prestressed against one another in the axial direction. This can be effected, for example, by means of a spring element, in particular a spiral spring (preferred) or an elastic element, for example an elastomer element. The pressure pieces can be designed such that they guide each other in the axial direction such that they can only be pivoted or rotated together in the circumferential direction.For the mutual guidance of the pressure pieces, mutually related guide devices of the pressure pieces can engage in one another. The pivot device of the protective flap device for the protective flap can be configured between the pressure pieces in the axial direction. In order that the pressure pieces remain configured to be movable relative to one another, the pivoting device is mounted in the axial direction in at least one of the two pressure pieces, preferably mounted in a sliding manner. This preferably relates to both pressure pieces. By means of the pivoting device, a torque can be introduced into the pressure pieces or the clutch assembly.The guide devices can be designed as axially elongated guide devices. In this case, at least one guide projection of one pressure piece can be guided in the axial direction in a guide recess of the other pressure piece. Furthermore, apart from the pivoting device, the pressure pieces can be designed crown-shaped and inserted into one another by means of their serrations. The serrations of both pressure pieces are interlocked with each other or the guide projections of both pressure pieces are inserted into each other in such a way that a torque can be transmitted with respect to the pivot axis from the one pressure piece to the other pressure piece and vice versa.Two guide devices directly adjacent in the circumferential direction of only a single pressure piece of the clutch assembly can be connected to one another by means of a radially inner circumferential connection (increased stability).In this case, the circumferential connection is (also) configured in particular on a free end section of the two guide devices.The coupling assembly can be configured between two mounting devices of the protective flap, which are furthermore mounted pivotably or rotatably on the coupling axis. In this case, a relevant mounting device can be designed as a mounting tab protruding away from the protective flap. The mounting device or the mounting tab can have a through-recess for mounting the protective flap on the coupling axle.Furthermore, the clutch assembly can have a clutch surface of the clutch of the protective flap device on at least one axial outer side. In particular, this relates to both axial outer sides. And at least one mounting device of the protective flap can have a coupling surface of the coupling of the protective flap device on an axial inner side. In particular, this relates to both mounting devices.For the transmission of force within the protective flap device, two mutually related clutch surfaces of the clutch assembly and of an assembly device can be designed as friction surfaces and / or form-fit surfaces. Two mutually related coupling surfaces of the coupling assembly and of an assembly device may have mutually related coupling latching devices.A relevant coupling latching device can be designed as a form-fit latching device, which can be designed as a projection or a recess. In this case, one coupling surface can have a projection (coupling latching device or form-fit latching device) and the relevant other coupling surface can have a recess (coupling latching device or form-fit latching device).Preferably, a coupling surface of the coupling assembly has a projection and a respective other coupling surface of the mounting device has at least one recess; this can of course also be embodied in the opposite way.The coupling latching devices of the mutually relevant coupling surfaces can cooperate in such a way that the protective flap can be pivoted between the closed position and the open position both electromechanically and manually. - In particular, two mutually relevant coupling surfaces are respectively arranged on both sides of the coupling assembly between the coupling assembly and the relevant mounting device.For the transmission of force within the protective flap device, a coupling surface of the coupling assembly can have an individual coupling catch device for catching the coupling catch devices of the mounting device. A coupling surface of the mounting device can have at least two, in particular three, coupling latching devices which are arranged offset with respect to one another in the circumferential direction. Optionally, in each case two coupling latching devices directly adjacent in the circumferential direction can be configured at an angle of approximately: 80°, 85°, 90°, 95°, 100° or 105° on / in the coupling surface of the mounting device. The coupling surface of the mounting device can have coupling latching devices for a manual open position, an electromechanical pivoting and / or a manual closed position of the protective flap device.The protective flap device can be designed such that in its closed position and / or in its open position, a self-locking between the actuator and the clutch assembly or a preferably single pressure piece is substantially configured. The actuator can be seated on the clutch assembly in such a way that the clutch assembly prevents a further movement of the actuator. Furthermore, the actuator can be seated with a flat region on a flat region of the clutch assembly or on a flat region of a single pressure piece. These two regions are arranged on the actuator opposite one another, for example, in a region of the actuating device.The pivoting device of the protective flap device for the protective flap can be designed as a pin produced independently of the pressure pieces or as a pivoting device on a pressure piece. In the second case, a cross section of the pivot device is formed as far as possible in the shape of a segment of a circle or an ellipse.An integral configuration is understood to mean a configuration of the relevant component (holder, actuator, protective flap or pressure piece), in which there is only a single component which can be divided only under the destruction thereof. The component is made of a single original piece and / or a single original mass (plastic melt), which in turn is necessarily integral. Internal cohesion takes place (exclusively) by means of adhesion and / or cohesion. In this case, coating, etc., can additionally be present.The protective flap device may comprise a motor for actuating the actuator. In this case, the motor can be designed as an electric motor, a linear motor or a drive in this respect. The motor is preferably arranged in a housing. Furthermore, an actuator of the motor is operatively connected mechanically to the actuator, or the actuator of the protective flap device is designed as an actuator of the motor or vice versa. The holder can be screwed to the preferably housed motor. And the protective flap device can form a section of a connector housing of the high-voltage connector. The holder can be mounted on / in the connector housing or be a section of the connector housing.The high-voltage connector according to the invention comprises at least one connector housing and a protective flap device, wherein the protective flap device is designed according to the invention. In this case, the high-voltage connector can naturally have an electrical high-voltage contact device with at least one electrical high-voltage terminal. The high-voltage connector can be designed as an electrical module, for example for servicing or replacing the high-voltage connector.The high-voltage entity according to the invention comprises an electrical high-voltage device and a protective flap device and / or an electrical high-voltage connector, wherein the protective flap device and / or the high-voltage connector is configured according to the invention. - Such a high-voltage entity can be configured, for example, as an electrical component, an electrical module (e.g. for replacing the high-voltage device together with the high-voltage connector), an electrical device, an electrical apparatus (e.g. a charging station), an electrical unit, etc.A vehicle-in particular a motor vehicle (road vehicle, commercial vehicle, etc.), but also: rail vehicle, watercraft and / or aircraft-having an electric traction engine is understood to mean a motor vehicle which, in addition to an electric traction engine, can have a further non-electric drive, such as an internal combustion engine. That is, a vehicle with an electric traction motor may be understood to mean, for example, an electric vehicle (electric motor drive only), a hybrid electric vehicle, a fuel cell vehicle, etc.The invention is explained in more detail below on the basis of exemplary embodiments with reference to the appended schematic drawing, which is not true to scale. Sections, elements, components, units, components and / or diagrams which have an identical, univocal or analogous configuration and / or function are identified by the same reference symbols in the description of the figures (see below), the list of reference symbols, the patent claims and in the figures (FIG. ) of the drawing. A possible alternative, not explained in the description of the invention (see above), not shown in the drawing and / or not concluding, a static and / or kinematic reversal, a combination etc. to the exemplary embodiments of the invention or a component, a diagram, a unit, a component, an element or a section thereof can furthermore be gathered from the list of reference numerals and / or from the description of the figures.In the invention, a feature (section, element, component, unit, component, function, size, etc.) can be designed to be positive, i.e. present, or negative, i.e. absent. In this specification (description (description of the invention (see above), description of the figures (see below)), list of reference numerals, patent claims, drawing), a negative feature is not explicitly explained as a feature unless value is placed according to the invention on the absence thereof. That is, the invention actually made, rather than one constructed by the prior art, is to omit this feature.A feature of this specification may be applied not only in a stated manner, but also in another manner (isolation, summary, replacement, addition, division, omission, etc.). In particular, it is possible to replace, add or omit a feature in the patent claims and / or the description based on a reference sign and a feature or vice versa assigned thereto, in the description, the list of reference signs, the patent claims and / or the drawing. Moreover, a feature can thereby be designed and / or specified in more detail in a patent claim.The features of the description can also be interpreted as optional features (in view of the (initially mostly unknown) prior art); i.e. each feature can be understood as an optional, arbitrary or preferred feature, that is to say as a non-binding feature. Thus, a solution of a feature, optionally including its periphery, from an exemplary embodiment is possible, wherein this feature can then be transferred to a generalized inventive idea. The lack of a feature (negative feature) in an embodiment shows that the feature is optional (skilled in the art) with respect to the invention. Furthermore, in the case of a generic term for a feature, a generic term for the feature is also readable (optionally further hierarchical organization in subgatting etc.), as a result of which generalization of the feature is possible, e.g. with attention to equality and / or equivalence.The figures of the drawing show, merely by way of example and schematic:FIG. 1 is a side sectional view of an exemplary embodiment of a first embodiment of a protective flap device according to the invention for a high-voltage connector according to the invention,FIGS. 2 and 3 are a side sectional (FIG. 2 ) and a front (FIG. 3 ) perspective view from obliquely above, each showing an embodiment of a second embodiment of the protective flap device according to the invention,FIGS. 4 and 5 are front (FIG. 4 ) and side (FIG. 5 ) perspective views of a coupling assembly for mounting between a protective flap and a holder of the protective flap device of FIGS. 2 and 3, respectively,FIGS. 6 and 7 are side-sectional perspective views each showing an inner self-locking of the protective flap device in a closed position (FIG. 6 ) and an open position (FIG. 7 ) of the protective flap, andFIG. 8 is a perspective view from obliquely front of a CCS high-voltage connector for a vehicle with an exemplary embodiment of the second embodiment of the protective flap device according to the invention.The invention is explained in more detail below with reference to exemplary embodiments of two embodiments (FIGS. 1 and 2-8 ) of a safety flap device 2 for an electric high-voltage charging connector 0 (cf. FIG. 8 : CCS high-voltage charging connector 0 (cf. also above)) for a vehicle, which is designed as a high-voltage charging socket 0. Of course, the invention is also applicable to other electrical connectors (cf. above), in particular high-voltage connectors 0. In this case, the high-voltage connector 0 can be designed, for example, as a mounting connector 0, a built-in connector 0, optionally a flying plug connector 0, etc.Although the invention is described and illustrated in more detail by preferred exemplary embodiments, the invention is not restricted by the disclosed exemplary embodiments, but is of a more fundamental nature. Other variations can be derived from this and / or from the above (description of the invention) without departing from the scope of protection of the invention. The invention can be used in general in the electrical field, i.e. also in the non-automotive field, in an electrical high-voltage entity (cf. above). An exception is the ground-bound electrical energy technique and analogues thereto.In the drawing, only those spatial sections of an object of the invention are shown which are necessary for an understanding of the invention. Terms such as connectors and mating connectors, terminals and mating terminals, etc. are to be interpreted as synonyms, i.e. optionally each interchangeable. The explanation of the invention (cf. also above) on the basis of the drawing relates below inter alia to a pivot axis SA of the protective flap device 2, its axial direction Ar (non-directional), its radial direction Rr (non-directional) and / or its circumferential direction Ur. The pivot axis SA is preferably coaxial to a coupling axis 430 (see below).FIG. 1 shows an exemplary embodiment of the first embodiment of the protective flap device 2 according to the invention. the protective flap device 2 comprises a holder 20, an actuator 30 and a pivotable protective flap 50. the protective flap 50 is arranged on the holder 20 or on / in the protective flap device 2 so as to open and close a plug face 10 of the high-voltage connector 0 (cf. FIG. 8 ) so as to be pivotable about the pivot axis SA. For this purpose, the protective flap 50 can be shut and fro electromechanically as intended between a closed position G (FIG. 7 ) and an open position O (FIG. 6 ) of the protective flap device 2 by means of the actuator 30.For this purpose, the actuator 30 engages the protective flap 50 in a translatory manner, wherein a radial lever 52 of the protective flap 50 (FIG. 1 ) or on the protective flap 50 (FIGS. 2 to 8 ) translates the translatory movement of the actuator 30 into a rotatory movement of the protective flap 50. For this purpose, the actuator 30 has an actuating device 304, which is in particular designed as an actuating recess 304 and gives the actuator 30 in the region of the actuating recess 304 the appearance of a claw in which a pivoting device 404, which is in particular pin-shaped, of the protective flap 50 or of the protective flap device 2 is accommodated. The claw can be constituted by a single claw section or a plurality of claw sections, in particular two claw sections.The pivoting device 404 is configured to be pivotable about the pivot axis SA, wherein the rotational movement of the pivoting device 404 about the pivot axis SA is generated by a translatory movement of the actuating recess 304. In this case, the pivoting device 404 moves both slightly translationally and slightly rotationally in the actuating recess 304, wherein the pivoting device 404 also carries along the translatory movement of the actuator 30. The translatory movement portion of the pivoting device 404 within the actuating recess 304 is preferably substantially perpendicular to the translatory movement of the actuator 30.FIGS. 2 to 7 show an exemplary embodiment of the second embodiment of the protective flap device 2 according to the invention, wherein the protective flap device 2 is designed analogously to the protective flap device 2 of FIG. 1 and further comprises a clutch 40 or an actuator decoupling clutch 40. By means of the coupling 40, the protective flap 50 can be manually pulled back and forth between the closed position G (FIG. 7 ) and the open position O (FIG. 6 ) of the protective flap device 2 as intended. That is, the actuation of the protective flap 50 by means of the actuator 30 is bypassed. The clutch 40 is configured in a force flow between the actuator 30 and the protective flap 50, wherein the protective flap 50 can be decoupled from a holding force of the actuator 30 by means of the clutch 40.The actual coupling (cf. in particular FIGS. 2 and 3 ) is located between two mounting devices 54 of the protective flap 50, which mounting devices are in particular configured as mounting brackets 54, and a coupling assembly 400 (coupling surfaces 550 of the mounting device 54 and coupling surfaces 450 of the coupling assembly 400), which coupling assembly is preferably configured in the shape of a drum or box, which coupling assembly is accommodated therebetween. Both the mounting brackets 54 and the coupling assembly 400 are preferably seated on a coupling axle 430 which is provided or mounted on / in the holder 20 so as to be somewhat movable to and fro in the axial direction Ar (play). Between the inner sides of the mounting brackets 54 (coupling surfaces 450) and the relevant outer sides of the coupling assembly 400 (coupling surfaces 550), the actual coupling of the protective flap device 2 is configured.For an electromechanical pivoting (cf. also FIGS. 6 and 7 ) of the protective flap 50, the mutually relevant coupling surfaces 550, 450 of the mounting tabs 54 and of the coupling assembly 400 each bear firmly, in particular frictionally and / or positively, against one another, such that a torque can be transmitted in this way, in particular from the coupling assembly 400 via the mounting tabs 54 to the protective flap 50 (cf. below: coupling latching device 452 engages in coupling latching device 552). That is, the clutch 40 is engaged. The protective flap 50 and the coupling assembly 400 can be pivoted substantially (play) by the same angle. For this purpose, the actuator 30 acts with its actuating device 304 in particular on the clutch assembly 400, for which purpose the clutch assembly 400 has the pivoting device 404.For the manual pivoting (cf. in particular FIGS. 4 and 5 ) of the protective flap 50, the respective above fixed connection (cf. above the mutual position of the coupling latching devices 452, 552) between the mutually relevant coupling surfaces 550, 450 of the mounting brackets 54 and the coupling assembly 400 is released, so that the protective flap 50 can be pivoted independently of the coupling assembly 400. That is, the clutch 40 is disengaged. No substantial torque is transmitted between the protective flap 50 and the clutch assembly 400. A torque that can still be transmitted in this case results only from a sliding frictional force of the mounting lugs 54 on the clutch assembly 400.In order that the clutch 40 can be disengaged, the clutch assembly 400 is designed to be resilient, elastic or compressible and re-stretchable in the axial direction Ar in such a way that a length of the clutch assembly 400 can decrease in the axial direction Ar and enlarge or enlarge and reduce again. - The clutch 40 is automatically set both for the electromechanical pivoting and for the manual pivoting, wherein the clutch assembly 400 assumes its enlarged size for the electromechanical pivoting and its reduced size for the manual pivoting in the axial direction Ar. A force for reducing the size of the coupling assembly 400 results from a force for manually pivoting the protective flap 50.A force flow during the electromotive pivoting of the protective flap 50 takes place starting from the motor-driven actuator 30 via the clutch assembly 400 and the engaged clutch 40 into the protective flap 50, wherein the clutch pit 400 also pivots. - A force flow during the manual pivoting of the protective flap 50 takes place starting from the protective flap 50 via the disengaging and then disengaged clutch 40, wherein the clutch assembly 400 is not pivoted and is retained by the actuator 30.Two mutually related coupling surfaces 550, 450 of an individual mounting bracket 54 and of the coupling assembly 400 are explained in more detail below in terms of their design and their function (cf. in particular FIGS. 4 and 5 ). The explanations in this respect also relate in particular to the other coupling surfaces 550, 450 on the other side of the coupling assembly 400 in the axial direction Ar. In this case, the coupling surfaces 550, 450 are preferably of substantially circular design in a first approximation and in a plan view in the axial direction Ar and are arranged coaxially with respect to one another with respect to the coupling axis 430.The coupling surface 450 of the coupling assembly 400 preferably has a coupling catch 452 for catching the coupling catches 551, 552, 553 of the coupling surface 550 of the mounting device 54. In this case, the clutch latching device 452 is designed in particular as a form-fit latching device 452 and is preferably designed as a projection, wherein a recess can of course likewise be used. - Depending on a configuration of the clutch 40, the clutch latching device 452 can comprise more than one projection and / or more than one recess.Furthermore, the coupling surface 550 of the mounting device 54 preferably has three coupling catch devices 551, 552, 553 offset in the circumferential direction Ur. The clutch latching device 551 is designed for a manual open position O, the clutch latching device 552 for an electromechanical pivoting and the clutch latching device 553 for a manual closed position G. The relevant clutch latching device 551, 552, 553 is designed in particular as a form-fit latching device 551, 552, 553 and is preferably designed as a recess, wherein a projection can of course likewise be used. - Depending on a configuration of the clutch 40, the clutch latching device 551, 552, 553 can comprise more than one recess and / or more than one projection; only condition is that they are designed substantially identically to one another so that they can interact with the clutch latching device 452 of the clutch assembly 400.The preferably single coupling catch device 452 of the coupling assembly 400 on one side serves to catch the coupling catch devices 551, 552, 553 of the mounting device 54. If the coupling catch device 452 catches with the coupling catch device 552 on the middle in the circumferential direction Ur, the protective flap 50 can be moved by electric motor from its open position O into its closed position G and from its closed position G into its open position O.Now for the two cases, in which the protective flap 50 is to be moved manually and the clutch latching device 452 is latched to the clutch latching device 552 which is central in the circumferential direction Ur. When the protective flap 50 is moved manually, the clutch assembly 400 compresses on account of a cooperation of the projections provided between the mutually relevant clutch surfaces 450, 550; that is to say, on the one hand, the projection 452 of the clutch assembly 400 and, on the other hand, the projections formed between the clutch residual devices 551 & 552 and 552 & 553 (cf. FIG. 5 ). This, of course, occurs on both sides of the clutch assembly 400, thereby disengaging the clutch 40.If the protective flap 50 is moved from its closed position G manually into its open position O (initial position: clutch residual device 452 and clutch residual device 552 are engaged), the clutch 40 disengages and the clutch residual device 452 snaps into the clutch residual device 553. If the protective flap 50 is moved from its open position O manually into its closed position G (initial position: clutch residual device 452 and clutch residual device 552 are engaged), the clutch 40 disengages and the clutch residual device 452 snaps into the clutch residual device 551. - By actuating the actuator 30, the clutch residual device 452 can be brought back into engagement with the clutch residual device 552.In order for the clutch assembly 400 to be designed to be springable, elastic or compressible in the axial direction Ar, the clutch assembly 400 can have two pressure pieces 410, 420, which are opposite one another in the axial direction Ar, are in particular arranged rotatably on the clutch axis 430 and preferably engage one another in such a way that they guide one another in the axial direction Ar. In this case, a spring element 440 is configured, in particular on the coupling axis 430, which spring element mechanically prestresses the two pressure pieces 410, 420 with respect to one another in the axial direction Ar. The spring element 440 is in particular designed as a spiral spring 440, an elastic element, an elastomer element, etc. The spring element 440 realizes, in particular, a reengagement of the clutch 40 after its disengagement.For mutual guidance, the pressure pieces 410, 420 have guide devices 411, 412; 421, 422 by means of which the pressure pieces 410, 420 mutually engage one another, as a result of which they can only be pivoted or rotated jointly in the circumferential direction Ur (coupling assembly 400 without spring element 440). For actuating the clutch assembly 400, the preferably pin-shaped pivot device 404 is configured between the two pressure pieces 410, 420, for which purpose the pressure pieces 410, 420 are correspondingly recessed so that the actuator 30 can engage the pivot device 404The first pressure piece 410 comprises at least one or preferably at least two guide projections 411 (guide devices 411) which are in particular designed as guide pins 411. Here, two guide projections 411 directly adjacent to one another in the circumferential direction Ur preferably do not have a radially inner circumferential connection (see below). Furthermore, the first pressure piece 410 comprises at least one or preferably at least two guide recesses 412 (guide devices 412), which are in particular configured as longitudinal guide recesses 412, wherein one guide recess 412 can be configured between two guide projections 411 in the circumferential direction Ur.The second pressure piece 420 comprises at least one or preferably at least two guide projections 422 (guide devices 422) which are in particular designed as guide pins 422. Here, two guide projections 422 directly adjacent to one another in the circumferential direction Ur preferably have a radially inner circumferential connection 423. Furthermore, the second pressure piece 420 comprises at least one or preferably at least two guide recesses 421 (guide devices 421) which are in particular configured as longitudinal guide recesses 421, wherein one guide recess 421 can be configured between two guide projections 422 in the circumferential direction Ur.Within the clutch assembly 400, the guide projections 411 of the first pressure piece 410 engage in the guide recesses 421 of the second pressure piece 420, and the guide projections 422 of the second pressure piece 420 engage in the guide recesses 412 of the first pressure piece 410. By means of this mutual guidance by the guide devices 411, 412; 421, 422 a transferability of a torque from one pressure piece 410 / 420 to the other pressure piece 420 / 410 is also ensured.The protective flap device 2 is preferably designed in such a way (cf. FIGS. 6 and 7 ) that, in the closed position G and / or in the open position O, the actuator 30 is seated on the clutch assembly 400 or on one of the pressure pieces 410, 420 in such a way that the protective cap device 2 itself inhibits itself in its own movement. The actuator 30 prevents a further movement of the clutch assembly 400 and the clutch assembly 400 prevents a further movement of the actuator 30.See FIG. 6, in which a portion above the actuator 304 of the actuator 30 abuts a radial portion of the thrust piece 420. And see FIG. 7, in which a portion below the actuator 304 of the actuator 30 abuts a portion of the thrust piece 420 extending in the circumferential direction Um and the radial direction Ra. This can of course be realized analogously with the pressure piece 410.Finally, FIG. 8 also shows a CCS high-voltage connector 0 with a preferably multi-part connector housing 1 and two plug-in faces 10, 12. Furthermore, this figure shows a housed motor 60 (cf. above), by means of which the protective flap 50 can be pivoted via the actuator 30 and the clutch assembly 400. The motor 60 or a housing of the motor 60 can be fixedly connected, in particular screwed, to the holder 20.
