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 around 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 a return spring for a second connection is known.

[0010] A rotatable connector is known from DE 10 2015 114 570 A1.

[0011] From DE 102 54 529 A1 a rotatable connector with a spring is known, but without a cover element.

[0012] A rotatable connector with a spring, but also without a cover element, is known from US 2024 / 0 039 221 A1. Disclosure of the invention

[0013] 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.

[0014] 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

[0015] 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.

[0016] 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.

[0017] 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, particularly one connected to a cable, is provided in the interior of the outer housing. The second connection is rotatable relative to the first connection. The second connection can, for example, rotate between a first position and a second position relative to the first connection. The second connection is preferably coupled to a spring element, which particularly preferably forces the second connection into a defined position.

[0018] This advantageously provides a particularly compact connector that takes up little space. The second connection is particularly well protected against external influences (e.g., mechanical impacts, moisture, dampness, splashing water, temperature fluctuations, etc.), thus improving the operational reliability and service life 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 because the second connection, especially when not under load (i.e., without manual manipulation or an inserted device connector), is preferably in the defined position or is automatically brought into the defined position.Being forced into the defined position ensures that the user always finds the second connector in the same or nearly the same position before connecting it to the consumer connector. 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 connector is not clearly visible), as the user always encounters a similar or identical insertion point and can routinely plug in or connect the consumer connector in the same way. Operation is thus simplified, safer, and faster: The user experience is improved. Safety is also enhanced; for example, quick and easy connection can be very advantageous in rain or snow.Finally, protection against unauthorized use of the second port and protection against unauthorized removal of a consumer connector connected to the second port are advantageously provided in a simple manner.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] For example, a first position (rotational position) and a second position for the second connector 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 an axis of rotation.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] For example, the defined position may be one in which a user has a particularly good view of the second port. It may be a position in which the second port is facing the eyes of a user of average height, for example, pointing upwards or into an upper hemisphere (against gravity).

[0030] For example, the spring element may be arranged, attached, or coupled to the second connection or to a connection abutment of the second connection. The spring element may, for example, be arranged on or mounted on an outer surface of the second connection.

[0031] For example, the spring element may be arranged, attached, coupled to, or mounted on an outer housing element (e.g., the base element, another cover element, or a housing shell) or on an outer housing abutment. The spring element may also be arranged or mounted on an inner surface of the outer housing element.

[0032] It may be provided, for example, that the spring element is arranged, fixed, or attached, in particular directly or immediately, between the second connection and the outer housing element.

[0033] The term "show" is used synonymously with the term "comprise" unless otherwise stated.

[0034] In a further training, it is provided that the second connection 13 is designed to be rotatable relative to the first connection 12 about the longitudinal axis L of the connector 1.

[0035] 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.

[0036] 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°.

[0037] This rotatability (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.

[0038] 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°.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] In a further development, it is provided that, in the case of a straight cable exit of the consumer connector, the cover element can be mounted on the base element without a gap when the second connection is in the first position, and in the case of an angled cable exit of the consumer connector, in particular a cable exit angled by 90°, the cover element can be mounted on the base element without a gap when the second connection is in the second position, wherein the defined position is the first position.

[0047] This advantageously ensures that for many devices that are typically used outdoors (e.g., grill, lawnmower, hedge trimmer, etc.) and that often have a straight cable exit at the consumer connector, the user always finds the second connection in a position suitable for this cable exit design, and then the cover element can be directly placed in the closed position.

[0048] If, during normal use of the connector, the first position is in the lower hemisphere (with respect to gravity) or points (more) downwards, the operation of the connector is further advantageously safer, especially in damp weather (snow, rain, fog), as the risk of moisture penetrating the second connection is reduced.

[0049] Alternatively, it can be stipulated, for example, that the defined position is the second position.

[0050] This has the advantage of making it particularly easy for a user to connect a consumer connector with an angled cable exit to the second port. With an angled cable exit, the insertion direction differs from the cable exit direction, which makes inserting the consumer connector somewhat less precise. Inserting such a consumer connector into the second port, which is pressed into the second position, can therefore be done more routinely; there is no need to force the connector in, for example, against the force of the spring element.

[0051] If, during normal use of the connector, the second position is located in the upper hemisphere (relative to gravity) or points (more) upwards, the insertion process is further facilitated. The second connection is advantageously oriented towards the field of vision of a (normally sized) user.

[0052] In a training course, it is stipulated that the spring element is selected from the following group: a spiral spring; a coil spring, a leaf spring, an volute spring, a compression spring, a tension spring, a torsion spring.

[0053] A coil spring can be advantageously installed in a very space-saving manner for the chosen application. For example, it can be positioned between the second connection and the outer housing element.

[0054] A coil spring can advantageously make the connector particularly cost-effective.

[0055] A leaf spring can advantageously have a particularly small space requirement.

[0056] An evolute spring can advantageously provide a particularly high restoring force and a particularly high stability of the restoring mechanism (into the defined position) while requiring little space.

[0057] A compression spring enables a particularly compact design of the connector.

[0058] A tension spring advantageously allows for a particularly high angle of rotation of the second connection relative to the first connection.

[0059] A torsion spring advantageously enables a particularly compact design of the connector. At the same time, it also allows a defined axial distance between the second terminal and the outer housing to be easily bridged without requiring the abutments to be positioned particularly close to the opposite part.

[0060] Alternatively or additionally, it is provided that the spring element comprises a metal, in particular predominantly spring steel.

[0061] This results in a particularly stable and durable spring element. Furthermore, it allows for a particularly high spring constant, enabling the spring element to be compact, material-efficient, and / or lightweight while maintaining a defined desired spring force.

[0062] The spring element can, for example, be designed or constructed from stainless steel. In particular, it can consist entirely of stainless steel materials, or even just one material. A stainless steel design advantageously increases the service life of the spring element and / or the connector.

[0063] 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.

[0064] 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.

[0065] 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°.

[0066] 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).

[0067] 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°.

[0068] 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.

[0069] In a further training course, it is stipulated that a seal be provided between the base element and the cover element.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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, merely as an example. The hinge can be designed as a hinge with at least one pivot and at least one axis, e.g., a plug-in axis. Alternatively or additionally, a film hinge can be provided.

[0074] In a further training course, it is stipulated that a hinge be provided between the lid element and the base element.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.).

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] This advantageously allows for the connection of all common consumer connectors that are standard in different countries in 2023 and / or 2024.

[0090] 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.

[0091] 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.

[0092] 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

[0093] 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.

[0094] They show Fig. 1. Schematic representation of a connector, Fig. 2a a perspective view of a connector with the cover element open and with a second connector in a first position, Fig. 2b of the connector from Fig. 2a, in which the second connection is in a second position rotated 180° about a longitudinal axis relative to the first position, Fig. 3a A first perspective view of a connector with a closed cover element, Fig. 3b a second perspective view of the connector from Fig. 3a with closed lid element, Fig. 4.

[0095] 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 or has a longitudinal axis L and a transverse axis Q, which runs perpendicular to the longitudinal axis L. The connector 1 further comprises or has 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 (see . Fig. 2a, Fig. 2b, Fig. 4, Fig. 5a and Fig. 5b), here by way of example between a first position P1 and a second position P2. The second connection 13 is here by way of example coupled to a spring element 40, wherein the spring element 40 forces the second connection 13 by way of example into a defined position P0.

[0096] This ensures that the user always finds the second connection in the same position (the defined position P0), especially when the cover element 10 is open. 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), etc., the user can intuitively (virtually "blindly") connect or plug in the consumer connector 15 to the second connection.

[0097] 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 rotatable or hinged relative to the base element 9 about a pivot axis A from the first position S1 to the second position S2 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.

[0098] In the Fig. 2a to 3 the second connection 13 is designed to be rotatable relative to the first connection 12 about the longitudinal axis L of the connector 1, here by at least 180° (here, for example, there is approximately 180° between the first position P1 and the second position P2 when rotating about the longitudinal axis L, whereby the rotation can in principle also go further than from the first position P1 to the second position P2).

[0099] In the Fig. 4 to 5b the second connection 13 is designed to be rotatable relative to the first connection 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 are about 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 be further than from the first position P1 to the second position P2).

[0100] 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.

[0101] 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.

[0102] 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"), etc., applications can also be implemented using connector 1.

[0103] 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.

[0104] It is evident (see also) Fig. 2a to 5b), that the second connection 13 is well protected by the outer housing 8, e.g. from external influences (mechanical but also from fluid media, splashing water, dirt, grime, insects, etc.). Furthermore, a consumer connector 15 can be easily arranged in 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 5b not shown) unauthorized access to the second terminal 13 is prevented and / or the 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).

[0105] 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) or which is in a second position P2 rotated approximately 180° around the longitudinal axis L relative to the first position P1 ( Fig. 2b).

[0106] 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.

[0107] The Fig. Sections 2a to 5b are described together below.

[0108] 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).

[0109] The second connection, number 13, is located in Fig. 2a, Fig. 5a 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).

[0110] It goes without saying that the one in the Fig. 3a and Fig. The slot 27 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.

[0111] 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 10 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.

[0112] In the Fig. 2a and Fig. 5a shows particularly clearly that with a straight cable exit of the consumer connector 15, the cover element 10 can be mounted without gaps on the base element 9 when the second connection 13 is in the first position P1.

[0113] In the Fig. 2b and Fig. 5b shows particularly clearly that in the case of an angled cable exit of the consumer connector 15, especially in the case of a cable exit angled by 90°, the cover element 10 can be mounted without gaps on the base element 9 when the second connection 13 is in the second position P2.

[0114] It may be intended, for example, that the defined position P0 is the second position P2, as shown in the figures here. The second position P2 is shown here in the Fig. 1 to 5b a position in which the second connection 13 (especially with normal mounting of connector 1 on a vehicle 3, a horizontally positioned vehicle 3 and a user of average height) is oriented towards the user's field of vision or line of sight. The second connection 13 points "upwards" or into the upper hemisphere (with respect to gravity G). This offers the advantage that the user always finds the second connection 13 in the same position (defined position P0) and can therefore plug in the consumer connector 15 virtually "blindly," as well as the further advantage that, under good visibility conditions, coupling or plugging in the consumer connector 15 can be carried out even better and more precisely, without contortions. In the case of connector 1 of the Fig. 4 to 5b and in the case of a straight cable exit, after coupling the consumer connector 15 with the second terminal 13, the second terminal 13 can be moved towards the first position P1 by applying (a small) force, e.g., to the cable 14 (e.g., with one hand of the user) or to the cover element 10 (against the spring action of the spring element 40), and the cover element 10 can then be mounted on the base element 9, in particular without gaps, or folded onto the base element 9. To ensure that the cover element 10 is securely closed or mounted on the base element 9, it can be secured, for example, to the base element 9 by means of a clip connection and / or by means of locking tabs and / or by means of locking lugs and / or by means of a locking bracket, etc. Such mechanisms are also possible in all other conceivable embodiments.When the cover element 10 is opened, the spring element 40 can push the second connection 13 back towards the defined position P0 (here: the second position P2). This also simplifies opening the cover element 10; it becomes easier to lift (indirectly assisted by the spring element 40).

[0115] In other embodiments, the defined position P0 may alternatively be the first position P1. If this were the case in the connectors 1 shown here, the second terminal 13 would point towards the lower hemisphere (with respect to the direction of gravity G) in the defined position P0 (especially with the connector 1 in its normal position and, for example, a horizontally positioned vehicle 3). In this case (second position corresponds to the defined position P0), the second terminal would also be protected against direct ingress of moisture (e.g., rain or snow) even when the cover element 10 is open.

[0116] It is understood that in not all conceivable embodiments does a consumer connector 15 with a straight cable exit need to be in the first position P1 of the second terminal 13, nor does it mean that in not all conceivable embodiments does a consumer connector 15 with an angled cable exit need to be in the second position P2 of the second terminal 13 to close the cover element 10 without a gap. The embodiments shown here are merely exemplary.

[0117] The spring element 40 is shown here as a spiral spring 41 only as an example. It can, for example, be selected in other embodiments from the group consisting of: a helical spring, a leaf spring, an volute spring, a compression spring, a tension spring, a torsion spring.

[0118] The spring element 40, as an example, is made of a metal, particularly predominantly. Here, the spring element 40 can, for example, be made of spring steel or contain spring steel, particularly predominantly, especially more than 50%. The spring element 40 is, as an example, designed to be stainless.

[0119] 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.

[0120] 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 because gravity 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.

[0121] 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.

[0122] In the embodiment shown here as an example, the underside 83 and the upper side 84 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 84 slopes towards the distal end of the outer housing 8 and towards the underside 83. 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 83 and the upper side 84 run approximately parallel to each other or diverge from each other in the second outer housing section 82 as well.

[0123] How particularly good in Fig. 2a, Fig. 2b, Fig. 5a and Fig. As can be seen in Figure 5b, the insertion direction E of the second connection 13 is 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 and Fig. 5a 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.

[0124] In the exemplary embodiment of the Fig. 2a and Fig. 2b 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.

[0125] 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.

[0126] The insertion direction E can be defined, for example, as the insertion direction of the consumer connector 15 into the second connection 13.

[0127] A seal 17 is provided here as an example between the base element 9 and the cover element 10 (see Fig. 2a, Fig. 2b and Fig. 4) 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.

[0128] The lid element 10 is in the Fig. 1 to 3b are arranged, by way of example, in a foldable or pivotable manner on the base element 9. Here, the cover element 10 can be pivoted upwards, for example, in the direction of the first connection 12.

[0129] 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.

[0130] Between lid element 10 and base element 9 is in Fig. 1 to 2b show, for example, a hinge 18. This can be designed as a hinge 18, e.g., with a pin axis and pivot, or as a film hinge, or in the form of another hinge design or joint design.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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 guided. This opening is not completely closed by the cover element 10.

[0136] 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.

[0137] 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.

[0138] 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.
