Description

Field of invention

[0001] The invention relates to a connector. State of the art

[0002] The present invention relates to a connector, in particular a connector designed as a “Vehicle-To-Load” (V2L) connector.

[0003] Connectors known from the prior art are designed as V2L connectors or V2L connector adapters. In the course of vehicle electrification, it is sometimes possible not only to charge the vehicle's energy storage device (e.g., a battery) with energy (e.g., electrical energy), but also to draw energy from this energy storage device (e.g., up to 400V and / or up to 30A, typically from approximately 100V to 240V and / or up to 20A or even up to 25A, although these values ​​may vary depending on the country), particularly via the vehicle's charging socket or charging port. In other words, the energy can not only be used internally within the vehicle (e.g., to supply an electrical system or to power the vehicle), but it may also be possible to operate external (especially electrical) consumers using the energy storage device ("vehicle-to-load").that this energy is transferred to another vehicle ("Vehicle-to-Vehicle," V2V), fed into the power grid ("Vehicle-to-Grid," V2G), or fed into a residential unit or home network ("Vehicle-to-Home," V2H). In the following, all these and other energy extraction possibilities will be referred to as "Vehicle-to-Load" (V2L) for ease of reading; the other possibilities (V2V, V2G, W2H, etc.) are included. It is understood that standard cigarette lighter sockets (e.g., in the vehicle's interior) are not to be understood as V2L, nor are the (permanently installed) sockets in the vehicle interior that are available as accessories or special equipment in some vehicles, into which, for example, a Europlug or a USB plug can be inserted.

[0004] In many cases, energy is drawn from the energy storage system in a V2L application by inserting a connector into the vehicle's charging port (usually located on the vehicle's exterior). However, the mechanical connection of this vehicle-side charging port (e.g., Type 2 connector) is often incompatible with standard connectors (e.g., Schuko plugs or Europlugs) of electrical devices (e.g., lamps, lawnmowers, grills, etc.). Therefore, to utilize a vehicle's V2L capability, connectors designed as adapters (V2L adapters or V2L connector adapters) are available. These connectors feature a housing with a primary connector that connects to the vehicle, specifically its charging port.Furthermore, they have a second connection for connecting to a consumer connector. This second connection is either permanently attached to the connector housing or connected to the first via a longer cable that extends from the connector housing at one end. In the latter case, the second connection may be located on another connector housing, which in turn is connected to another end of the cable.

[0005] From US 2023 / 0137396 A1, a V2L cable system is known which has a first connector for coupling to a vehicle and a second connector or a multi-connector connected to it via a longer cable for connecting one or more consumers, so that overall an adapter system for V2L applications is realized.

[0006] From CN 109177778 A a V2L connector adapter with two connections (vehicle-side first connection and consumer-side second connection) in a single connector housing is known.

[0007] From DE 11 2012 006 765 B4 a connector is known which has an outer housing, two terminals and a cover element, wherein the two terminals are designed to be rotatable relative to each other.

[0008] From the subsequently published DE 10 2023 212 804 B3, another connector adapter is known which has an outer housing, two terminals and a cover element, wherein the two terminals are designed to be rotatable relative to each other.

[0009] From DE 10 2022 000 665 A1 a cable connection device in the form of an adapter with return spring and ball joint for a second connection, but without a cover element, is known.

[0010] US patent 2024 / 0039221A1 describes a rotatable connector with a spring, but without a cover element. Disclosure of the invention

[0011] The invention is based on the understanding that such known connectors or cable systems, especially for V2L applications, are not particularly well suited for outdoor use under all conceivable weather conditions. In particular, operation in damp conditions (rain, snow, splashing water, etc.) poses a significant challenge with regard to operational reliability. Using a longer cable to connect the second terminal on the consumer side can help to relocate the second terminal outside the area exposed to moisture; however, such a cable requires a relatively large amount of storage space. Furthermore, the invention is based on the understanding that access to the second terminal on the consumer side can be very difficult in some cases, depending on the design of the consumer-side connector. One design, for example, might feature a straight connector exit, where, for example...The connector pins run approximately along the direction of a connected cable or line. Another design could be, for example, an angled connector outlet, where the connector pins run at an angle to the connected cable (e.g., rotated 90°). Furthermore, the invention is based on the understanding that users should always be able to operate such a connector safely and intuitively, even in dark, unclear, or restricted situations (e.g., a user's glasses are fogged up, the user is wearing gloves due to the cold, etc.). Users appreciate being able to connect the consumer connector to the second port intuitively and virtually "blindly," or to insert the consumer connector into the second port virtually "blindly."Furthermore, the invention is based on the understanding that conventional V2L connectors can easily lead to energy theft or the theft of a connected device. If the vehicle owner leaves the vehicle with the V2L connector plugged in, an unauthorized third party can easily connect their own device (possibly by first disconnecting the owner's electrical device) and illicitly draw energy from the vehicle's energy storage system for their own device. Alternatively, this unauthorized third party can simply steal the owner's connected device by unplugging its connector from the V2L adapter and then making off with the device.

[0012] Therefore, there may be a need to provide a device, in particular a connector, especially for V2L applications, that allows a consumer to be connected to the charging port or energy transfer port of another device, wherein the former device, in particular the connector, is designed to be particularly space-saving, offers high operational reliability, especially under adverse weather conditions (humidity, wetness), where access to the second (consumer-side) connection is as simple as possible, regardless of the consumer-side plug (straight cable exit vs. angled cable exit), where unauthorized connection of consumers can be prevented, and which can be operated virtually "blindly" by the user in many different, even restricted situations (e.g., in darkness, with gloves, with fogged glasses, parking close to a wall and poor accessibility, etc.).can be operated habitually (especially with regard to coupling the consumer connector to the second connection), and where theft of a connected consumer can also be easily prevented. Advantages of the invention

[0013] This need can be met by the subject matter of the present invention according to the independent claim. Advantageous embodiments of the present invention are described in the dependent claims.

[0014] According to a first aspect of the invention, a connector is proposed, configured for connecting to a mating connector of a device for extracting energy from the device, in particular from an energy storage device of the device. In particular, a connector is proposed that is configured for use in V2L applications. Specifically, the connector is configured to be coupled or connected to a charging port or an energy transfer port of a device. The device can be, for example, configured as a vehicle, energy storage system, power storage system, energy supply system (e.g., a charging station), wallbox, etc., which is particularly capable of bidirectional operation with respect to energy flow.

[0015] The connector has a longitudinal axis and a transverse axis (Q) that runs perpendicular to the longitudinal axis (L). The connector comprises an outer housing with a base element, a cover element, and an interior. A first connection for connecting to the mating connector of the device is provided on an outer surface of the outer housing, and a second connection for connecting to a consumer connector, in particular one connected to a cable, is provided in the interior of the outer housing. The second connection is rotatable relative to the first connection, in particular about a (connection) rotation axis. The second connection can, for example, rotate between a first position and a second position relative to the first connection.wherein the outer housing has a coupling element, wherein the second connection has a feedback element, wherein the coupling element and the feedback element are operatively connected to each other in such a way that a set position or rotational position of the second connection relative to the first connection is maintained.

[0016] This results in a particularly compact connector that takes up little space. The second connection is advantageously well protected against external influences (e.g., mechanical impacts, moisture, dampness, splashing water, temperature fluctuations, etc.), thus improving the operational reliability and lifespan of both the connector and any connected device. Furthermore, connecting a device is particularly convenient and easy, especially since the connection is easily possible regardless of the cable exit type, simplifying operation and improving operational reliability. This is achieved through the coupling or interaction...The interaction of the coupling element and the negative feedback element ensures that the set position of the second connection relative to the first connection is maintained. This advantageously means that the user finds the second connection in the set position before connecting it to the consumer connector. It also advantageously prevents (unintentional) displacement or rotation of the second connection during the plugging process, which significantly facilitates, for example, one-handed insertion of a consumer connector. "Wobbling" during the plugging process is also advantageously prevented. This facilitates use even in difficult situations (e.g., in darkness, with limited tactile sensitivity (e.g., due to gloves), with fogged-up glasses, etc., when parked close to a wall so that the second connection is not clearly visible), as the user finds the desired insertion situation or position of the second connection.The user can adjust the position of the second connector, and this position remains constant during the plugging process. This allows the user to insert or connect the consumer connector in a familiar, secure position. Operation is thus simplified, safer, and faster, improving the user experience. Safety is enhanced; for example, quick and easy connection can be very advantageous in rain or snow. Finally, this provides simple protection against unauthorized use of the second connector and against the unauthorized removal of a consumer connector connected to it.

[0017] The set position of the second connection relative to the first connection is maintained, particularly in force-free conditions (e.g., when only gravity and / or the weight of an inserted consumer connector are acting), through the interaction of the coupling element and the feedback element. Moving, especially rotating, the second connection relative to the first requires a defined force, for example, applied by an operator or user. Once the new position is set or reached, this new set position of the second connection relative to the first connection is maintained.

[0018] For example, the coupling element can be designed separately from the second connection. This allows for the advantageous implementation of a modular design. The coupling element can then be used for various connectors with different connector geometries.

[0019] For example, it may be provided that the coupling element interacts or couples with the feedback element at a single point or with a small area, or that they are in a operative relationship. It may also be provided, for example, that the feedback element, particularly at any given time, only mechanically couples with a coupling area of ​​the coupling element that corresponds to at most 10% of the total area of ​​the coupling element. Or, that the coupling element, particularly at any given time, only mechanically couples with a feedback area of ​​the feedback element that corresponds to at most 10% of the total area of ​​the feedback element.

[0020] For example, the coupling element may be arranged at a distance from the second connection, particularly when viewed in a direction parallel to the (connection) axis of rotation or in a direction perpendicular to the (connection) axis of rotation. It should be understood that, for the purpose of evaluating this distance, the feedback element should not be associated with the second connection. In other words, apart from the feedback element, the coupling element and the second connection can, by way of example, be spaced apart from each other.

[0021] For example, the coupling element may be arranged, attached, coupled to, or mounted on an outer housing element of the outer housing (e.g., the base element, another cover element, or a housing shell). The coupling element may also be located inside the outer housing.

[0022] For example, the coupling element can be designed in a ring shape (either closed or with an annular gap). This allows, for instance, at least one conductor to be advantageously routed through the coupling element, or the coupling element to be arranged around a conductor. This simplifies assembly and reduces the space required for the outer housing.

[0023] The longitudinal axis can, for example, be an axis that extends parallel to a plugging direction of the first connection into a counter-connection of the device (e.g., of a vehicle) through the first connection and / or through the second connection.

[0024] The cover element, together with the base element, can enclose or define the interior space, in particular enclose or define that part of the interior space in which the second connection is located.

[0025] The first connection can be located, for example, on the base element, e.g., in a first section of the outer casing or the base element. The second connection can be located, for example, on the base element, e.g., in a second section of the outer casing or the base element that differs from the first section.

[0026] For example, a first position (rotational position) and a second position for the second connection can be provided. In the first position, a consumer connector with a straight cable exit can be inserted particularly easily, and in the second position, a consumer connector with an angled (e.g., 90° angled) cable exit can be inserted particularly easily, so that the cable does not collide with the base element and / or the cover element of the outer housing or run in a sharply curved manner inside. It is understood that, in principle, further positions can be provided, which lie, for example, between the first and second positions, or which—starting from the first position and a specific direction of rotation—lie behind the second position. For example, the first and second positions are rotated apart by at least 20°, preferably at least 30°, about a (connection) rotational axis.

[0027] It may be designed, for example, that the second connection can only be rotated from the first position to the second position in a single direction (e.g., only clockwise or only counterclockwise when looking at the second housing section). Alternatively, it may be designed, for example, that the second housing section is rotatable in opposite directions relative to the first connection, thus allowing, for example, a transition from the first position to the second position in both possible directions.

[0028] For example, it may be provided that the first and second terminals are located directly adjacent to each other. It may be provided, for example, that the first and second terminals are not connected by a longer, flexible cable running outside the housing, i.e., not by a cable or such line running freely between the two terminals. It may be provided, for example, that the outer housing is rigid and that the first and second terminals are fixed to the outer housing (except for the rotation of the second terminal). It may be provided, for example, that the first and second terminals have a substantially defined or fixed distance relative to each other, particularly when viewed along a longitudinal axis of the connector.along a connecting line from the first connection to the second connection.

[0029] The outer housing can, for example, be designed as a single piece. It can be rigid (except for the rotation of the second connection relative to the first connection) (opening the cover element does not compromise the rigidity of the outer housing). It can be designed such that the first connection is captive to the outer housing, and the second connection is also captive to the outer housing. In particular, it can be provided that the outer housing and / or its base element does not consist of two elements that can rotate relative to each other.

[0030] For example, the outer housing may be designed to include means that prevent the interior from being opened (e.g., by opening the cover). Such means could be selected from the following: a lock, at least one eyelet on the base and one on the cover (through which, for example, a padlock or similar item can be threaded), or a bolt. This advantageously prevents unauthorized connection of a device to the connector or its second terminal. It also advantageously prevents unauthorized removal of a connected device and thus theft of the connected device.

[0031] The outer casing can, for example, comprise or consist of metal, particularly predominantly. Alternatively or additionally, it can also contain plastic. It is particularly advantageous for the outer casing to be manufactured as an injection-molded part or assembled from a plurality of injection-molded parts.

[0032] The outer housing can, by way of example, include additional elements besides the base element and the cover element, which in particular define an outer contour. For instance, the outer housing can have another cover element. This additional cover element, for example, can be permanently attached to the base element (e.g., screwed on) when the connector is assembled and cannot be moved relative to it.

[0033] For example, the set or defined position may be one in which a user has a particularly good view of the second connector. It may be a position in which the second connector is facing the eyes of a user of average height, for example, pointing upwards or into the upper hemisphere (against gravity). The set position can vary depending on the individual user and their preferences or physical characteristics, and / or the specific arrangement of the connector on the device, etc. A user can also set different positions (e.g., one after the other).

[0034] The term "show" is used synonymously with the term "comprise" unless otherwise stated.

[0035] In a further training course, it is stipulated that the second connection is designed to be rotatable around the longitudinal axis of the connector relative to the first connection.

[0036] The longitudinal axis here is, for example, the (connecting) rotation axis.

[0037] This provides a particularly high degree of flexibility for finding a user-friendly insertion position for a consumer connector. Furthermore, it allows for the easy insertion of both straight and angled consumer connectors, enabling secure and protected placement within the outer housing while maintaining the connector's compact dimensions.

[0038] The rotation about the longitudinal axis of the second connection relative to the first connection can be, for example, at least 90°, preferably at least 180°.

[0039] This rotation (e.g., at least 90°, preferably at least 180°) can be configured, for example, between the first position and the second position. In other words, a rotation from the first position to the second position or vice versa can, for example, require a rotation of at least 90° or at least 180°, particularly about the longitudinal axis.

[0040] The second connection can, for example, be rotated in the second position relative to the first position by an angle of rotation in the range of 165° to 195°, preferably by 180°.

[0041] Alternatively or additionally, it is provided that the second connection is designed to be rotatable relative to the first connection around the transverse axis of the connector.

[0042] The transverse axis here is, for example, the (connecting) rotation axis.

[0043] This provides a particularly high degree of flexibility for finding a user-friendly insertion position for a consumer connector. Furthermore, it allows for the easy insertion of both straight and angled consumer connectors. Additionally, it enables a particularly simple electrical connection between the first and second terminals. Finally, it allows for a particularly compact connector design.

[0044] The second connection can be designed to rotate around the transverse axis by at least 30°, preferably at least 45°, relative to the first connection.

[0045] This rotation (e.g., at least 30°, preferably at least 45°) can be configured, for example, between the first position and the second position. In other words, a rotation from the first position to the second position or vice versa can, for example, require a rotation of at least 30° or at least 45°, particularly about the transverse axis.

[0046] In a further development, it is provided that the second connection can be rotated relative to the first connection in such a way that, when the consumer connector is plugged into the second connection, the cover element can be mounted on the base element without a gap, especially in the case of a straight cable exit of the consumer connector and in the case of an angled cable exit of the consumer connector.

[0047] This design advantageously provides particularly good protection for the second connection against external influences and against misuse of the connector. Furthermore, it allows for a particularly compact connector design. Unauthorized disconnection of a coupled consumer connector is also effectively prevented. These advantages are also achievable regardless of the chosen cable exit of the consumer connector.

[0048] An optional slot for cable entry, described below, does not preclude gap-free mounting of the cover element to the base element. "Gap-free mounting" can mean, for example, that the cover element can be moved into a first (closed) position without any gap to the base element, i.e., that the cover element can be completely closed (and is not held (partially) open by the consumer connector with an unsuitable cable exit), so that the interior is protected against the ingress of fluids, dirt, and / or debris through a lateral gap between the cover element and the base element. If the cover element is not permanently attached to the outer housing element, gap-free mounting can also mean, for example, placing or resting the (initially separate) cover element onto the base element. This can then, for example,It should be provided that the cover element is fixed to the base element after this assembly, in particular in a captive manner.

[0049] In a further development, it is provided that one is designed as a friction element consisting of a coupling element and a counter-feedback element, wherein another is designed as a spring element consisting of a coupling element and a counter-feedback element, wherein the spring element is in mechanical contact with the friction element, wherein the spring element is pre-tensioned when contacting the friction element, or wherein the spring element is in a pre-tensioned state when contacting the friction element.

[0050] In other words, there can be a first configuration in which the coupling element is designed as a friction element and the counter-coupling element is designed as a spring element. In this case, the spring element can, for example, be pre-tensioned between the friction element and the second connection. There can also be a second configuration in which the counter-coupling element is designed as a friction element and the coupling element is designed as a spring element.

[0051] This advantageously results in a particularly cost-effective and simple design for preventing the second connection from rotating. The spring element is pre-tensioned against the friction element, so that for the second connection to rotate relative to the first connection, a force exerted by the spring element on the friction element must be overcome, specifically a frictional force. A user can, for example, set a position or rotational position of the second connection by applying a certain force to it – against the frictional force. This position is then maintained due to the frictional force.

[0052] The friction element can, for example, have a friction lining onto which the spring element is pressed or compressed.

[0053] In principle, it is also conceivable that the friction element is designed as a type of pinion disc or pinion ring. In this case, the spring element is "captured" in a defined position of the second connection relative to the first connection between two pinions (in a kind of pocket formed between the pinions or ribs). This prevents unintentional rotation of the second connection. If rotation is desired, a defined force must be exerted on the second connection (e.g., laterally), which compresses the spring element (e.g., vertically) so that the spring element jumps over the adjacent pinion or rib and is "captured" in the next pocket. For example, the pocket size can be designed to have only a slight oversize along the trajectory (laterally) of the spring element.In this way, the set position of the second connection is very constant and can only vary minimally - especially without external force (e.g., at most 2 mm or at most 1 mm or at most 0.5 mm).

[0054] The spring element can, for example, be formed in one piece or integrally as a spring workpiece. This can be achieved, for example, through a suitable choice of material or a defined shape. However, it is also possible for the spring element to be formed in multiple parts. It can, for example, include a spring (e.g., a coil spring, etc.) that presses another element (e.g., a plunger, separate from the spring) against the friction lining.

[0055] For example, the defined force required for rotation can be easily adjusted by the distance between the second connection and the coupling element. This distance affects the compression of the spring element and thus also the frictional force that must be overcome when the second connection is to be rotated. This distance can be fixed (e.g., factory-set according to customer specifications) or adjusted by the user.

[0056] In a further development, it is provided that the friction element is made of an elastic material and in particular consists of rubber or caoutchouc, especially to a predominant extent.

[0057] This advantageously provides a friction element that is particularly easy to manufacture and cost-effective.

[0058] Alternatively or additionally, the friction element is provided to have at least one rib facing the spring element. This at least one rib is specifically oriented such that the spring element is compressed when the second connection rotates and passes through the rib.

[0059] It may be provided, for example, that at least one rib is aligned in such a way that it intersects a trajectory of the spring element when the second connection is rotated relative to the first connection.

[0060] The inclusion of at least one rib provides the user with haptic and / or acoustic feedback at at least one defined point regarding the set position of the second connector relative to the first. This allows for precise adjustment of the second connector even in very poor visibility. For example, such a rib can be positioned to indicate when the first or second position has been reached. If multiple ribs are present, they can indicate several positions (e.g., the first and second positions, and possibly additional positions). Upon reaching the rib and the resulting increased force required to overcome it, the user receives feedback about the position.

[0061] It may be designed with exactly one rib. However, it may also be designed with multiple ribs. For example, the ribs may form the pinion disc or pinion ring described above. It may also be designed, for example, with the ribs being equidistant. Regardless of the design, it may be designed with at least one of the ribs having a different height than the other ribs. This allows, for example, haptic and / or acoustic feedback for reaching specific positions. For instance, reaching the first position and / or the second position can be indicated in this way.

[0062] Alternatively or additionally, it is provided that the spring element projects towards the friction element from the second connection or from the outer housing.

[0063] This advantageously enables a coupling or interaction between the friction element and the spring element using simple means.

[0064] The protrusion from the outer casing can, for example, mean a protrusion of an outer casing element. It can, for example, refer to a protrusion inside the casing.

[0065] In a further training, it is provided that the coupling element or the counter-coupling element is arranged in a ring shape around the (connection) axis of rotation.

[0066] This advantageously allows for a particularly space-saving design of the connector.

[0067] For example, if the second connection is rotatable about its longitudinal axis, the coupling element can be disc-shaped, e.g., oval or round. The coupling element can be particularly advantageously designed as a ring with a through-opening (e.g., for a cable passage). In other embodiments, no through-opening is provided; the coupling element is, for example, shaped like a circular or oval disc.

[0068] For example, if the second connection is rotatable around the transverse axis, the coupling element can be designed like a finger ring. Coupling with the counter-coupling element can be made, for example, on an outer side (pointing away from the center and the (connection) axis of rotation) or on an inner side.

[0069] In a further development, it is provided that the coupling element has a stop element, wherein the stop element is configured to couple with the counter-coupling element and to stop a rotation of the second connection relative to the first connection in a defined position.

[0070] This advantageously prevents the user from adjusting or twisting the second connection too far in any one direction. Damage to at least one cable that may be connected to the second connection is thus advantageously avoided.

[0071] It is understood that exactly one stop element can be provided. In this case, for example, rotation can be limited to a maximum of 360° (from one side of the stop element to the other). However, multiple stop elements can also be provided. This can advantageously create redundancy if, for example, a stop element breaks (e.g., snaps off). Furthermore, this allows for a well-defined rotation range to be set, particularly when stop elements are spaced apart on the coupling element.

[0072] It is understood that the stop element – ​​unlike the rib described above – cannot be overcome (or, in particular, not without damage). The stop element prevents the second connection from rotating, even under normal user force. The rib, however, can be overcome with a defined normal user force, allowing the second connection to be rotated over the rib.

[0073] In a further training, it is stipulated that when the consumer connector is plugged into the second connection, the consumer connector is located completely inside the outer housing.

[0074] This advantageously provides particularly good protection for the second connection and also for the consumer connector against external influences, thus increasing the service life of these components and improving operational reliability. Furthermore, this makes it more difficult for unauthorized third parties to tamper with the second connection and / or the consumer connector.

[0075] In a further development, it is provided that the outer housing has a first outer housing section and a second outer housing section, wherein the first outer housing section faces the first connection, wherein the second outer housing section faces away from the first connection, wherein the second outer housing section is angled relative to the first outer housing section, wherein a first angle between the first outer housing section and the second outer angle section lies in a range of 15° to 60°, preferably from 20° to 50°.

[0076] This advantageously makes it more difficult for moisture to penetrate the interior of the outer housing. For example, a cable from the consumer connector can be routed out of the interior through the angled second section of the outer housing. It is particularly advantageous for the second section of the outer housing to point downwards (geodesically downwards), especially when the connector is coupled to the mating connector of the device (e.g., a vehicle, etc.). Furthermore, it is advantageous that any moisture or liquid that has accumulated in the outer housing can be channeled in a defined manner to the lowest point – viewed from the direction of gravity – thus increasing operational reliability. Such a lowest point can, for example, be located as far away as possible from the second connection, e.g., within the second section of the outer housing. An opening for the drainage of moisture or liquid can be provided.Liquid should be provided in the area of ​​the lowest point. Furthermore, the angled design advantageously ensures that a cable from the consumer connector, regardless of its exit direction (straight or angled), always leaves the outer housing in approximately the same direction and does not need to be bent within the interior, or at least runs largely straight. The angled design also allows the consumer cable to be routed into the interior through a defined opening in the second section of the outer housing. If this second section of the outer housing and this opening are located in this way, moisture cannot penetrate into the interior along the cable due to gravity in damp or wet environments (e.g., rain).

[0077] In a further development, it is provided that an insertion direction of the second connection is angled relative to the longitudinal axis by a second angle, wherein the second angle, in particular an absolute value of the second angle, lies in a range of 15° to 60°, preferably from 20° to 50°.

[0078] This advantageously allows the cable of a consumer connector to be routed away from the connector without significant bending or curvature, regardless of the cable exit. When the connector is coupled or plugged into the mating connector of the device (e.g., the vehicle, etc.), the second terminal can, for example, point diagonally downwards in the first position. In this position, a consumer connector with a straight cable exit can be inserted particularly easily, and the cable runs diagonally downwards. If the second housing section is rotated into the second position (e.g., by approximately 160° to 200° around the longitudinal axis and / or approximately 45° to 110° around the transverse axis), the second terminal points diagonally upwards in this example. In this second position, a consumer connector with an angled cable exit can now be easily inserted.In this case, too, the cable of the consumer connector runs diagonally downwards. This advantageously allows for a well-defined cable routing direction for the consumer, regardless of the cable exit point of the consumer connector. This, in turn, provides a high degree of flexibility for connecting consumers.

[0079] In a further training course, it is stipulated that a seal be provided between the base element and the cover element.

[0080] This provides particularly good protection for the interior and thus the second connection against external influences (e.g., the ingress of moisture, dampness, splashing water, dirt, grime, insects, etc.). Operational reliability and service life are thus significantly increased.

[0081] In a further training, it is provided that the lid element is hinged on the base element and / or that the lid element 10 is hinged relative to the base element 9.

[0082] This advantageously enables particularly easy operation of the outer casing. Furthermore, it prevents the cover element from being accidentally lost. Additionally, it also makes it particularly easy to prevent unauthorized access.

[0083] In the second alternative, the cover element can, for example, be arranged on another cover element. In this case, a hinge can be provided between the cover element and the other cover element, for example. The hinge can be designed as a hinge with at least one pivot and at least one axis, e.g., a pivot pin. Alternatively or additionally, a film hinge can be provided.

[0084] In a further training course, it is stipulated that a hinge be provided between the lid element and the base element.

[0085] This design advantageously enables particularly safe and easy operation of the lid. The outer casing is then designed to be especially robust and durable, as the lid closes along a defined trajectory (dictated by the hinge). Furthermore, this design advantageously prevents the lid element from being accidentally lost. It also makes it particularly easy to prevent unauthorized access.

[0086] The hinge can be designed as a hinge with at least one pivot and at least one axle, e.g., a plug-in axle. Alternatively or additionally, a film hinge can be provided.

[0087] In a further training course, it is stipulated that a slot for the routing of a cable of the consumer connector is provided in the base element and / or in the cover element.

[0088] This advantageously increases operational reliability. Pinching of the cable as it exits the outer housing is effectively avoided, as is deformation of the base element and / or the cover element in the area of ​​the cable entry.

[0089] A slot seal can be installed in the slot, for example. This provides excellent protection for the interior against the ingress of fluids, dirt, grime, insects, etc. Operational reliability and service life are thus improved.

[0090] When the cover element is in the first (closed) position, the cable can be routed through the slot from the interior without being pinched. The presence of this slot does not prevent a gap-free installation or a gap-free closing of the cover element.

[0091] In a further training course, it is stipulated that the first connection is designed for connection to a high-voltage energy system of the device (e.g., the vehicle, etc.).

[0092] This advantageously enables the extraction of high power (several kW) from the device or the energy storage of the device without jeopardizing the operational safety of the connector or of connected consumers.

[0093] Alternatively or additionally, it is provided that the first connector is selected from the group comprising: Type 1 connector, Type 2 connector, Type 3A connector, Type 3C connector, CHADEMO connector, CCS COMBO TYPE1 connector, CCS COMBO TYPE2 connector, GB / T connector, Supercharger connector.

[0094] This advantageously enables connection to all common device connections or mating connectors of a device (e.g., a vehicle, an energy storage system, a power storage system, a power supply system, a wall box, etc.) that are common in 2023.

[0095] It is understood that the first connection may also be designed as a connection type that only becomes relevant in the period after the filing of this application.

[0096] In a further training course, it is stipulated that the second connection is designed for connecting a consumer connector for a low-voltage network, in particular for voltages from 90V to 440V.

[0097] This advantageously enables the connection of devices that can also be plugged into standard household sockets or three-phase sockets. The transmission of high power (several kW) to the device is thus facilitated without compromising the operational safety of the connector or the connected devices.

[0098] Alternatively or additionally, it is provided that the second connection, in particular designed as a socket, is selected from the group comprising: Type A, Type B, Type C, Type D, Type E, Type F, Type G, Type H, Type I, Type J, Type K, Type L, Type M, Type N, CEE, USB-A, USB-C.

[0099] This advantageously allows for the connection of all common consumer connectors that are standard in different countries in 2023 and / or 2024.

[0100] It is understood that the second connection may also be designed as a connection type that only becomes relevant in the period after the filing of this application.

[0101] In a further training course, it is stipulated that the connector is designed to transmit currents of at least 1A, or at least 5A, or at least 10A, or at least 16A, or at least 20A.

[0102] This advantageously enables the connector to be used for transmitting high power. This allows for the broadest possible and most reliable use of the connector, from operating low-power LED lights to operating high-power devices such as electric grills, heaters, hair dryers, power tools, etc. Drawings

[0103] Further features and advantages of the present invention will become apparent to the person skilled in the art from the following description of exemplary embodiments, which, however, are not to be interpreted as limiting the invention, with reference to the accompanying drawings.

[0105] Fig. Figure 1 shows a schematic representation of a connector 1. This connector is designed for connection to a mating connector 2 of a device, which is exemplified here as a vehicle 3, for extracting energy from the device, in particular from an energy storage device 4 of the device (here, for example, the vehicle 3). The connector 1 comprises a longitudinal axis L and a transverse axis Q, which runs perpendicular to the longitudinal axis L. The connector 1 further comprises an outer housing 8 with a base element 9, a cover element 10, and an interior 11, wherein a first connection 12 for connection to the mating connector 2 of the device (here, for example, the vehicle 3) is provided on an outer surface of the outer housing 8, exemplified here in a first section 6 of the outer housing 8.Inside the inner chamber 11 of the outer housing 8, a second connection 13 is provided (here shown by way of example in a second section 7 of the outer housing 8) for connection to a consumer connector 15 of a consumer 16, in particular connected to a cable 14. The second connection 13 is designed to be rotatable relative to the first connection 12 about a (connection) rotation axis R (see . Fig. 2a, Fig. 2b, Fig. 4, Fig. 5a, Fig. 5b and Fig. 6a), here by way of example, between a first position P1 and a second position P2. The outer housing 8 here by way of example has a coupling element 40. The second terminal 13 here by way of example has a negative feedback element 41. The coupling element 40 and the negative feedback element 41 are operatively connected to each other, i.e., coupled to each other, i.e., interact with each other. The operative relationship is designed in such a way that a rotational position of the second terminal 13 set – e.g., by a user or operator – relative to the first terminal 12 is maintained (see Fig. 1, 4 to 6c).

[0106] This allows a user to adjust the second connector 13, particularly when the cover element 10 is open, to a desired, defined position P0, in which the second connector 13 then remains. Despite the rotatability of the second connector 13, it cannot slip or rotate on its own due to the interaction of the coupling element 40 and the negative feedback element 41 (e.g., due to gravity (represented here by an arrow with the reference symbol G) or due to the weight of the consumer connector 15). Therefore, even in poor visibility conditions (darkness, fogged glasses, parking against a wall, etc.) or with limited tactile sensitivity (e.g., the user is wearing gloves), the user can intuitively (virtually "blindly") connect or plug in the consumer connector 15 to the second connector.This is particularly easy to do with one hand, as the second connector does not need to be held in an ideal position for insertion with the other hand. Furthermore, the user can advantageously adjust the second connector 13, for example in rainy conditions, so that the connector face with the live wires is not exposed to the path of raindrops. Even in this set direction or defined position P0, which may (but does not have to) differ from an ideal insertion position, the second connector 13 remains in place due to the interaction of coupling element 40 and feedback element 41. Depending on the design of the connector 1, the user will also find the second connector in the desired position even after a prolonged absence. Thus, a user can set a position that suits their needs (e.g.,depending on the user's height and / or the height of the charging socket on the device or on the vehicle 3 into which the connector 1 is plugged.

[0107] In the embodiments of the Fig. In sections 1 to 6c, it is provided – merely as an example – that the coupling element 40 is designed separately from the second connection 13. Fig. Figure 6a shows that, for example, it is arranged or attached to a support or retaining element 47 inside the outer housing 8, in an internal section 46 located between the first connection 12 and the second connection 13. This allows, for example, a modular design to be advantageously implemented. The coupling element 40 can be used, for example, for various connectors 1 with different connector geometries.

[0108] In the embodiments of the Fig. In sections 1 to 6c, it is provided – merely as an example – that the coupling element 40 interacts or couples with the feedback element 41 only at specific points or over a small area. The feedback element 41 is here, by way of example, designed as a projection of the second connection 41 extending towards the coupling element 40. It is provided here, by way of example, that the feedback element 41, particularly at any given time, mechanically couples only with a coupling surface F of the coupling element 40 that corresponds to at most 10% of the total coupling area (in particular, the total coupling area facing the feedback element 41) of the coupling element 40. Thus, no large-area surface interaction takes place, as, for example, when two elements rub against each other in a sliding bearing (a sliding bearing bushing and a cylindrical element inserted therein and sliding on the inner wall). Fig. Figure 6b shows an example of the coupling surface F.

[0109] If – in another embodiment not shown here – the coupling element 40 is designed as a kind of projection that extends in the direction of the counter-coupling element 41 arranged or formed at the second connection 13, then it can be provided that the coupling element 40, in particular at any given time, only mechanically couples with a counter-coupling surface of the counter-coupling element 41 which corresponds to at most 10% of the total counter-coupling surface (in particular the total counter-coupling surface facing the coupling element 40) of the counter-coupling element 41.

[0110] In the embodiments of the Fig. 1 to 6c is provided - merely as an example - that the coupling element 40 is arranged at a distance from the second connection 13, here in each case in a direction parallel to the (connection) rotation axis R (in Fig. 1 to 3b and 6: the (connecting) rotation axis corresponds to the longitudinal axis L; in Fig. 4 to 5b: the (connection) rotational axis R corresponds to the transverse axis Q). In other embodiments, the coupling element 40 can, for example, be designed like a kind of finger ring, so that the spacing is transverse or perpendicular to the (connection) rotational axis R (the coupling element 40 then lies radially outside or inside the second connection 13). It should be understood that, for the evaluation of this spacing, the feedback element 41 is not to be associated with the second connection 13. In other words, if the feedback element or feedback element 41 is disregarded, the coupling element 40 and the second connection 13 are shown here as being spaced apart from each other, in each case in the axial direction. In the case of a finger ring design, the coupling element 40 can, for example, be designed as a kind of pinion ring. The ribs 44 and pockets 50 can then, for example,They may be arranged radially inside (in the image of the finger ring: pointing towards the finger) or radially outside (in the image of the finger ring: pointing away from the finger on the outside of the ring).

[0111] In the embodiments of the Fig. 1 to 6c is provided – by way of example only – that the coupling element 40 is attached to an outer housing element 86 of the outer housing 8 (e.g. the base element 9 or a further cover element 85 or a housing shell or as in Fig. 6 shown on the retaining element 47 of the outer housing 8) is arranged or attached or coupled to it or mounted on it. The coupling element 40 is, for example, arranged inside the outer housing 8.

[0112] In the embodiments of the Fig. Figures 1 to 6c provide – by way of example only – that the coupling element 40 is designed in an annular form (here: closed annular form; in other embodiments, an annular gap is also conceivable). This allows, for example, at least one line 48 to be advantageously routed through the coupling element 40, or the coupling element 40 to be arranged around a line 48. This simplifies assembly and reduces the space required for the outer housing 8.

[0113] The cover element 10 can, for example, have a first, closed position S1 and, for example, a second, open, in particular fully open, position S2 (especially with respect to the base element 9). The cover element 10 can, for example, be arranged to rotate or fold from the first position S1 to the second position S2 relative to the base element 9 about a (cover) pivot axis A on an outer housing element 86 of the outer housing 8, in particular on the base element 9 or on a further cover element 85 of the outer housing 8.

[0114] In the figures, the direction of gravity is indicated by an arrow labeled "G". The connectors 1 are shown in a normal mounting or plugging position, particularly in the case of a device standing on a horizontal surface or a vehicle 3 standing on a level surface.

[0115] In the Fig. In sections 2a to 3 and 6a, the second terminal 13 is designed to be rotatable relative to the first terminal 12 about the longitudinal axis L of the connector 1, here by at least 180° (for example, approximately 180° lies between the first position P1 and the second position P2 when rotating about the longitudinal axis L, whereby the rotation can in principle also extend beyond the first position P1 to the second position P2). For example, the longitudinal axis L corresponds to the (terminal) rotation axis R.

[0116] The interaction between coupling element 40 and negative feedback element 41 prevents, for example, the unintentional rotation of the second connection 13 from a position set by a user, towards the first position P1 or the second position P2, for example during the insertion of the consumer connector 15. This allows the consumer connector 15 to be inserted easily, even with one hand.

[0117] In the Fig. In sections 4 to 5b, the second terminal 13 is designed to be rotatable relative to the first terminal 12 about the transverse axis Q of the connector 1, here by way of example by at least 30°, preferably by at least 45° (here, by way of example, there is a rotation of approximately 45° to 60° between the first position P1 and the second position P2 when rotating about the transverse axis Q, whereby the rotation can in principle also extend beyond the first position P1 to the second position P2). Here, the transverse axis Q corresponds by way of example to the (terminal) rotation axis R.

[0118] The interaction between coupling element 40 and negative feedback element 41 prevents, for example, the unintentional rotation of the second connection 13 from the first position P1 or a (deliberately) set position in the direction of the second position P2, e.g. due to gravity G, especially when inserting the consumer connector 15 or with the consumer connector 15 inserted, but also without the consumer connector 15 inserted.

[0119] The longitudinal axis L here is an axis that extends parallel to the insertion direction of the first terminal 12 into a mating terminal of the device (e.g., of the vehicle 3) through the first terminal 12. It can also extend through the second terminal 13.

[0120] In Fig. For the sake of clarity, connector 1 is not yet coupled or connected to the device (here: the vehicle 3) and not yet to the consumer 16, shown here as an example of a hairdryer.

[0121] Connector 1 can be considered a type of connector adapter that allows the consumer connector 15 to be electrically connected to the mating connector 2 of the vehicle 3. Connector 1 can therefore be used for V2L applications, in which energy is drawn from the (high-voltage) energy storage device of the device (here: the vehicle 3). In principle, V2G ("Vehicle-to-Grid"), V2V ("Vehicle-to-Vehicle"), V2H ("Vehicle-to-Home") applications, etc., can also be implemented using connector 1.

[0122] Advantageously, the connector 1 has only small external dimensions, e.g., when connected or plugged together or coupled with the mating connector 2 of the device (here: of the vehicle 3), it protrudes at most 35 cm from the device (here e.g., from the vehicle 3), preferably at most 30 cm, particularly preferably at most 25 cm, and most preferably at most 20 cm.

[0123] It is evident (see also) Fig. 2a to 6a), that the second connection 13 is well protected by the outer casing 8, e.g. from external influences (of a mechanical nature but also from fluid media, splashing water, dirt, grime, insects, etc.).

[0124] Furthermore, a consumer connector 15 can be easily arranged inside the interior 11 and coupled to the second connection 13, regardless of its cable exit (straight or angled), without cable kinking. Finally, it is generally possible to easily (in the Fig. (1 to 6c not shown) unauthorized access to the second terminal 13 is prevented and / or theft of a consumer 16 connected to the second terminal 13 is prevented (to prevent theft it is sufficient that the consumer connector 15 is located in the interior 11 and is larger than an opening in the outer housing 8).

[0125] The Fig. 2a and Fig. Figure 2b shows a perspective view of a connector 1 with the cover element 10 open and with a second terminal 13 located in a first position P1 ( Fig. 2a, but also Fig. 6a) or which is in a second position P2 rotated approximately 180° around the longitudinal axis L relative to the first position P1 ( Fig. 2b).

[0126] The Fig. 3a and Fig. Figure 3b shows a first perspective view of a connector 1 with a closed cover element 10 and a front end facing the viewer ( Fig. 3a) or with a rear end facing the viewer ( Fig. 3b). In Fig. Figure 3b shows two cables 14. These represent the cable exit from the outer housing 8 for the two different positions, the first position P1 and the second position P2, which are for different cable exits (straight cable exit, see Figure 3b). Fig. 2a and angled cable exit, see Fig. 2b) can be selected. In the illustrated embodiment of the Fig. 2a to 3b usually only have a single cable 14 which leaves the outer casing 8.

[0127] The Fig. Sections 2a to 6c are described together below.

[0128] The second terminal 13 can be rotated relative to the first terminal 12 as an example, such that when the consumer connector 15 is plugged into the second terminal 13, the cover element 10 can be mounted on the base element 9 without a gap (see Fig. 3a, Fig. 3b, Fig. 5a, Fig. 5b), especially in the case of a straight cable exit of the consumer connector 15 (see Fig. 2a, Fig. 5a) and in the case of an angled cable exit of the consumer connector 15 (see Fig. 2b, Fig. 5b).

[0129] The second connection, number 13, is located in Fig. 2a, Fig. 5a (but also in Fig. 6a) in the first position P1 and in Fig. 2b, Fig. 4, Fig. 5b in the second housing position P2. The rotatability of the second terminal 13 relative to the first terminal 13 (in particular from the first position P1 to the second position P2 or vice versa) is indicated by the double arrow in each case (see Fig. 2a, Fig. 2b, Fig. 4).

[0130] It goes without saying that the one in the Fig. 1, Fig. 2a, Fig. 2b and Fig. The slot 19 shown in Figure 3b and described below for cable routing does not preclude gap-free mounting of the cover element 10 on the base element 9 or gap-free closing of the cover element 10 on the base element 9. This also applies in the same way to the cable routing of the connectors 1 of the Fig. 4 to 5b. In the illustrated figures, the gap-free assembly or gap-free closing of exemplary connectors 1 refers in particular to the fact that an inserted consumer connector 15 does not prevent the closing of the cover element 10 or its transition into the first (closed) position P1. This is shown in the Fig. 3a, Fig. 3b, Fig. 5a and Fig. 5b clearly visible: the cover element 10 and the base element 9 are in contact with each other on the side walls and on the back of the connector, in particular without gaps.

[0131] In the Fig. 2a and Fig. 2b shows that the housing tapers to a point at the rear end (distal end) of the second connection 13 and, by way of example, has a first chamfer 71 or a first chamfer section and a second chamfer 72 or a second chamfer section. The second connection 13 is arranged in the first chamfer section by way of example (in Fig. 2a shows this pointing downwards, in Fig. 2b upwards). The first chamfer 71 or the first chamfer section and the second chamfer 72 or the second chamfer section advantageously also facilitate gap-free closing of the cover element 10 on the base element 9 with a particularly compact design in length and height of the outer housing 8 or the cover element 10. In particular, the first chamfer 71 with the second connection 13 arranged in this (first) chamfer section enables a very compact design in height and length, since even in the second position P2 (with angled cable exit of the consumer connector 15) a cable exit area 31 (see Fig. 2b) of the consumer connector 15 does not or only very slightly protrudes beyond an upper edge 32 of an element arranged in the interior 11, which has the second connection 13, in the second section 7 of the outer housing 8.

[0132] In the embodiments of the Fig. In sections 1 to 6c, it is provided – by way of example only – that the coupling element 40 is designed as a friction element 42. Furthermore, it is optionally provided, and by way of example only, that the counter-feedback element 41 is designed as a spring element 43. The spring element 43 is in mechanical contact with the friction element 42. For example, it is in a pre-tensioned state when the friction element 42 makes contact, or the spring element 43 is pre-tensioned when the friction element 42 makes contact (here, for example, compressed relative to a rest position of the spring element 43). For example, the spring element 43 is pre-tensioned here between the second connection 13 and the friction element 42.

[0133] In other embodiments not shown here, the feedback element 41 can, for example, be designed as a friction element 42, and the coupling element 40 as a spring element 43. The spring element 43 can then, for example, be in mechanical contact with the friction element 42. The spring element 43 is, by way of example, in a pre-tensioned state when the friction element 42 makes contact.

[0134] This prevents the second connection from rotating. The spring element 43 is pre-tensioned against the friction element 42, so that a force exerted by the spring element 43 on the friction element 42, in particular a frictional force, must be overcome to rotate the second connection 13 relative to the first connection 12. A user can, for example, adjust the position or rotational position of the second connection 13 by applying a certain force to the second connection 13, in particular against a frictional force and / or an overcoming force to overcome a mechanical structure, such as a rib 44 along a trajectory T (see Fig. 6b) of the feedback element, here: by way of example the spring element 43, relative to the friction element 42 when the second connection 13 is rotated. This set position is then maintained due to the friction force and / or the overcoming force.

[0135] The friction element 42 can, for example, have a friction lining (or be designed as a friction lining) against which the spring element 43 is pressed. Such a friction lining can, for example, have an increased coefficient of friction (relative to the spring element 43) (e.g., compared to a smooth and hard surface or a lubricated or oiled surface; for example, the coefficient of friction, in particular the static friction coefficient, can be at least 0.2, or even at least 0.3, or even at least 0.4). This is the case in the embodiments of the Fig. 1 to 6c are examples of this case.

[0136] In principle, it is also conceivable that the friction element 42 is alternatively or additionally (here: additionally) designed as a kind of pinion disc 49 (or in other embodiments as a kind of pinion ring) (see e.g. Fig. 6a, Fig. 6b). The spring element 43 is "trapped" in a well-defined position of the second connection 13 relative to the first connection 12 between two pinions (in a kind of pocket 50 or compartment formed between the pinions or ribs 44). This prevents unintentional rotation of the second connection 13. If rotation is desired, a defined force must be exerted on the second connection 13 (e.g., laterally, rotation about the (connection) axis of rotation R), which compresses the spring element 43 (e.g., vertically, i.e., perpendicular to the rotational movement) so that the spring element 43 jumps over the adjacent pinion or rib 44 (against which it is currently resting) and is "trapped" in the next pocket 50. It may be provided, for example, that the pocket size or compartment size has only a slight excess along the trajectory T (lateral) of the spring element 43.In this way, the set position of the second connection 13 is very constant and can vary only minimally - especially without external force - (e.g. at most 2 mm or at most 1 mm or at most 0.5 mm). For example, a friction element 42 designed as a pinion disk 49 may have a plurality of ribs 44 (e.g., between 10 and 90 ribs 44 arranged circumferentially around 360°, preferably between 30 and 75 ribs 44, e.g., 36, 40, or 72 ribs 44). It may be provided, for example, that the ribs 44 of the pinion disk 49 have inclined flanks (in the form of a ramp) that facilitate the compression of the resilient element 43. The flanks may, for example, have an angle of 30° to 75° to the perpendicular; the higher the angle, the shallower the ramp. The flanks of a rib 44 may have the same angle on both sides of the apex of the rib 44.Alternatively, they can have different angles (this allows the tactile feel to be adjusted depending on the direction of rotation). The pinion disc 49 advantageously allows the second connection 13 to be rotated incrementally by a defined angle. In this way, (fairly) precise rotation angles or positions of the second connection 13 can be set, which are secured against accidental rotation.

[0137] The spring element 43 can, for example, be formed in one piece or integrally as a spring workpiece. This is well suited in Fig. 6a and Fig. 6c. This can be achieved, for example, through a suitable choice of material or a defined shape. Here, the spring element is designed, for example, as a closed oval ring 51 with a hollow interior. On its side facing the coupling element 40, the oval or the spring element 43 has a projection or a coupling rib 52. This allows, for example, a particularly well-defined, small coupling surface F to be provided for the coupling element 40 (here the friction element 42).

[0138] In other embodiments, not shown here, the spring element may also be designed in multiple parts. For example, it may include a spring (e.g., a coil spring, etc.) that presses another element (e.g., a plunger, separate from the spring) against the friction lining (not shown here).

[0139] For example, the defined force required for rotation can be easily adjusted by the distance between the second connection 13 and the coupling element 40 (or between the counter-coupling element 41 and the coupling element 40). This distance affects the compression of the spring element 43 and thus also the frictional force and / or the pressing force required to overcome a rib 44 when the second connection 13 is to be rotated. This distance can be fixed (e.g., factory-set according to customer specifications) or adjusted by the user.

[0140] In the embodiments of the Fig. 1 to 6c, for example, it may be provided that the friction element 42 is made of an elastic material and in particular comprises rubber or caoutchouc, especially predominantly. Alternatively, it may be provided that the friction element 42 merely comprises a friction lining made of the aforementioned materials, wherein the friction lining is arranged on a carrier material.

[0141] As described above, in the embodiments of the Fig. Figures 1 to 6c provide that the friction element 42 has at least one rib 44 facing the spring element 43 (here: a plurality of ribs 44). The ribs 44 are oriented (in their arrangement) such that the spring element 43 is compressed when the second connection 13 rotates and passes through a rib 44. In other words, the ribs 44 are arranged here, by way of example, such that they intersect the trajectory T of the spring element 43.

[0142] It is understood that in other embodiments, in addition to or as an alternative to the pinions or ribs 44 of the pinion disk 49, at least one rib 44 (a single rib 44 or a plurality of ribs 44) may be provided which has a different shape than the "usual" pinions or ribs 44. For example, such a "different" rib 44 may have a different flank angle (on one side or on both sides) and / or a different crest height than the "usual" ribs 44. This allows a user to receive defined (especially different) haptic and / or acoustic feedback at a specific position when rotating the second connector 13. For example, such a "different" rib may indicate that the first position P1 has been reached or that the second position P2 has been reached.

[0143] In the embodiments of the Fig. 1 to 6c is provided - only by way of example - that the spring element 43 projects from the second connection 13 in the direction of the friction element 42.

[0144] In the embodiments of the Fig. Figures 1 to 6c illustrate – by way of example only – that the coupling element 40 (in other embodiments the counter-coupling element 41) is arranged in a ring shape around the (connection) rotational axis R. In the Fig. In 1 to 3b, 6a it is arranged around the longitudinal axis L, preferably concentrically. In the Fig. 4 to 5b it is arranged around the transverse axis Q, preferably concentrically.

[0145] In the Fig. 6a and Fig. Figure 6b clearly shows that the coupling element 40 has a stop element 45, which is configured to couple with the negative feedback element 41 and to stop a rotation of the second connection 13 relative to the first connection 12 in a defined position P0. This stop element 45 is formed integrally with the coupling element 40. It is located in the trajectory T (see Figure 6b). Fig. 6b) of the feedback element 41. When the second terminal 13 is rotated and the feedback element 41 reaches the stop element 45, the stop element 45 blocks the feedback element 41. Further rotation of the second terminal 13 in the same direction is then no longer possible with normal force. This provides good haptic feedback for the user, indicating that the rotation in the selected direction has reached its limit. Further rotation could damage the stop element 45 and / or the feedback element 41. In the embodiment of the Fig. 6a and Fig. 6b provides exactly one stop element 45. This allows the second connection 13 to be rotated approximately 360°. For example, the rotation can start at approximately 0° (on the first side of the stop element 45) in the first position P1, reach the second position P2 at 180°, and return to the first position P1 at approximately 360° (on the second side of the stop element 45). This prevents excessive twisting or bending of the wires 48, which pass through the friction element 42 and are connected to the second connection 13. This reduces the risk of damage to the wires 48.

[0146] It is understood that more than one stop element 45 can be provided on or at the coupling element 40. In particular, at least two or exactly two stop elements 45 can be provided. If at least two of the stop elements 45 are arranged at a distance from each other on the coupling element 40 (with respect to the trajectory T), a smaller rotation angle range than approximately 360° can be set (e.g., 270°, 225°, 180°, 120°, 90°, 60°, etc.). This can be achieved, for example, in the embodiment of Fig. 4 to 5b may be advantageous.

[0147] In the Fig. 1, Fig. 2b, Fig. 4 and Fig. In 5b, the defined position P0 is shown as being identical to the second position P2. A user can set or select this second position P2, for example, if they want a particularly good view of the second connector 13 and / or want to plug in an angled consumer plug 15. Fig. In Figure 6a, the defined position P0 is, for example, the same as the first position P1. A user can select this first position P1, for example, when it is raining and / or when they want to plug a consumer connector 15 with a straight cable exit into the second port 13. It is understood that, in principle, the second port 13 can also have a different position than the defined position P0, or that there can be several defined positions P0. The position set by a user (and thus held by coupling element 40 and feedback element 41) can differ from the defined position P0.

[0148] In Fig. In Figure 6c, two circumferential grooves 53 can be seen at the second connection 13. By means of these grooves 53 or guide grooves (in principle, a single groove 53 is also conceivable), the second connection 13 is arranged, held, or mounted in a bearing element 54 or a bearing ring located inside the outer housing 8, in particular rotatably mounted (see also Fig. 6a).

[0149] With the consumer connector 15 plugged into the second terminal 13, the consumer connector 15 is shown here as an example completely arranged inside the interior 11 of the outer housing 8, see Fig. 2a, Fig. 2b, Fig. 5a and Fig. 5b.

[0150] The outer housing 8 here exemplarily comprises a first outer housing section 81 and a second outer housing section 82, wherein the first outer housing section 81 faces the first connection 12 and the second outer housing section 82 faces away from the first connection 12. The second outer housing section 82 is, by way of example, angled relative to the first outer housing section 81 (here it is angled downwards, in particular, gravity G also points downwards). A first angle W1 between the first outer housing section 81 and the second angled outer housing section 82 can, for example, be in a range of 15° to 60°, preferably from 20° to 50°. This advantageously prevents the ingress of splash water or rain from above into the interior 11.Furthermore, the cable routing for both positions P1, P2 of the second connection 12 is approximately the same, regardless of whether an angled consumer connector 15 (especially with approximately 90° cable exit) is arranged in the second position P2 or a straight consumer connector 15 is arranged in the first position P1.

[0151] In the illustrated embodiments of the Fig. As exemplified in paragraphs 1 to 5b, the bending on a lower side 84 of the outer housing 8, viewed along the longitudinal axis L starting from the first connection 12, begins earlier than on a upper side 83 of the outer housing 8.

[0152] In the embodiment shown here as an example, the underside 84 and the upper side 83 of the outer housing 8 run approximately parallel to each other only in the first outer housing section 81. In the second outer housing section 82, the upper side 83 slopes towards the distal end of the outer housing 8 and towards the underside 84. In other words, the angle of inclination on the upper side 83 is greater than the first angle W1 on the underside 84. The first angle W1 refers to the underside 84. However, there may also be embodiments in which the underside 84 and the upper side 83 run approximately parallel to each other or diverge from each other in the second outer housing section 82 as well.

[0153] How particularly good in Fig. 2a, Fig. 2b, Fig. 5a, Fig. 5b and Fig. As can be seen in Figure 6a, the insertion direction E of the second connection 13 is shown here as an example, angled relative to the longitudinal axis L by a second angle W2. The second angle W2, in particular its absolute value, can, for example, lie in a range of 15° to 60°, preferably from 20° to 50°. Fig. 2a, Fig. 5a and Fig. 6a the second angle W2 lies below the longitudinal axis L, in Fig. 2b and Fig. 5b it lies above the longitudinal axis L. Therefore, the angle specifications preferably refer to the absolute value of the second angle W2.

[0154] In the exemplary embodiment of the Fig. 2a, Fig. 2b and Fig. 6a This angled arrangement of the second connection 13 is achieved particularly easily by arranging the second connection 13 in or on the first chamfer section of the first chamfer 71, whereby an angled arrangement is of course also conceivable without this chamfer 71.

[0155] In the exemplary embodiment of the Fig. 4 to 5b the angled arrangement is achieved by a suitable rotation of the second connection 13 about the transverse axis Q.

[0156] The insertion direction E can be defined, for example, as the insertion direction of the consumer connector 15 into the second connection 13.

[0157] A seal 17 is provided here as an example between the base element 9 and the cover element 10 (see Fig. 2a, Fig. 2b, Fig. 4 and Fig. 6a). This seal 17 can, for example, be designed as a sealing cord. It can be arranged or mounted on the base element 9 and / or the cover element 10 (e.g., in a way that allows for non-destructive removal). In other embodiments, it can also be attached to the base element 9 and / or the cover element 10 in a way that is not removable without damage, e.g., by injection molding. The seal 17 enables a particularly good seal of the interior 11 against moisture, wetness, splashing water, dirt, grime, insects, etc.

[0158] The lid element 10 is in the Fig. 1 to 3b and 6a are arranged, by way of example, to be foldable or pivotable on the base element 9. Here, the cover element 10 can be pivoted upwards, by way of example, in the direction of the first connection 12.

[0159] In the embodiment of the Fig. In figures 4 to 5b, the cover element 10 is hinged relative to the base element 9. Here, the cover element 10 is coupled to another cover element 85. In this case, the other cover element 85 does not contribute to the enclosure of the interior space 11 or that part of the interior space 11 in which the second connection 13 is located. This interior space 11 (or part of the interior space 11) is shown here as an example – as also in the Fig. 1 to 3b - limited or enclosed or defined only by the base element 9 and the cover element 10.

[0160] Between lid element 10 and base element 9 is in Fig. Figures 1 to 3b and 6a show, by way of example, a hinge 18. This can be designed as a hinge 18, for example, with a pin axis and pivot, or as a film hinge, or in the form of another hinge design or joint design.

[0161] The hinge 18 is shown here as an example on a top surface 83 of the outer housing 8, approximately halfway along the length of the first outer housing section 81.

[0162] In the embodiment of the Fig. 4 to 5b the hinge 18 is arranged between the cover element 10 and the further cover element 85.

[0163] In the embodiment shown here, the Fig. In sections 1 to 3b, a slot 19 is provided in both the base element 9 and the cover element 10 for the passage of a cable 14 of the consumer connector 15. The two slots are aligned when the cover element 10 is closed (see Fig. 3b). It is understood that in other embodiments only the base element 9 or only the cover element 10 may have a slot 19 for the passage of the cable 14. In principle, the slot 19 can even be omitted entirely.

[0164] Each of the two slots 19 is fitted with a slotted seal 20. The slotted seal 20 can be formed integrally with the seal 17, which allows for particularly simple, secure, and durable installation. However, such a one-piece design is not strictly necessary.

[0165] In the embodiment of the Fig. 4 to 5b shows an opening or recess at the rear end of the base element 9, shown here as an example in the deepest part, through which the cable 14 can be routed. This opening is not completely closed by the cover element 10.

[0166] The first connector 12 is designed here as an example for connection to a high-voltage energy system of the device (here, by way of example, the vehicle 3). It is designed here as an example Type 2 connector. In other embodiments, the first connector 12 can be selected from the group comprising: Type 1 connector, Type 3A connector, Type 3C connector, CHAdeMO connector, CCS Combo Type 1 connector, CCS Combo Type 2 connector, GB / T connector, and Supercharger connector. Other connector types are, of course, also conceivable.

[0167] The second terminal 13 is designed for connecting a consumer connector 15 for a low-voltage network, in particular for voltages from 90V to 440V. The second terminal 13, specifically designed as a socket, can be selected from the following group, for example: Type A, Type B, Type C, Type D, Type E, Type F, Type G, Type H, Type I, Type J, Type K, Type L, Type M, Type N, CEE, USB-A, USB-C. Here, it is shown as an example for connecting a Schuko® plug commonly used in Germany.

[0168] Connector 1 is designed to transmit currents of at least 1A, 5A, 10A, 16A, or 20A, particularly at voltages between 90V and 440V. This allows even high-power devices, such as heaters, hair dryers, kettles, power tools, etc., to be operated safely and reliably in V2L mode using connector 1.
