[0003] Connector arrangement

[0004] State of the art

[0005] The present invention relates to a plug arrangement for an electrical plug connection.

[0006] Currently, a multitude of different solutions exist for connector arrangements for electrical connectors. A key requirement when providing connector arrangements that include a plug and a mating connector is to ensure the secure connection of a connector and prevent accidental disconnection. Furthermore, it is often required to keep the required operating force low compared to the direct insertion force required to avoid overloading the installer. This can be achieved, for example, by providing a transmission ratio between the plug and mating connector.

[0007] A well-known variant is the provision of a locking lever, by which a rotary movement performed by the user is converted into a linear movement with the help of a link in the lever and bolts in the mating connector.

[0008] However, due to the rotating movement, a lever usually requires a lot of space during installation.

[0009] A connector arrangement with a lever is known, for example, from DE 20 2013 000 998 U1. Another very common variant is the provision of a slider, which is moved perpendicular to the plugging direction between the plug and the mating connector. A corresponding link and bolt in the mating connector also generate a movement in the plugging direction (and thus perpendicular to the movement of the slider).

[0010] Like the lever, a slider that can be moved vertically or transversely to the plug-in direction requires a lot of space during installation.

[0011] Such a concept is known from DE 196 51436 A1.

[0012] There may therefore be a need to provide a connector assembly that is easy to use, has a low operating force when mating the plug and connector, and has a small space requirement, particularly during assembly.

[0013] Disclosure of the invention

[0014] 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.

[0015] According to one aspect of the invention, a connector assembly is proposed.

[0016] The plug arrangement has a plug, a mating plug, a slide, and a tooth arrangement. The plug can be plugged together with the mating plug along a plugging direction. The tooth arrangement has a first tooth contour, a second tooth contour, and a third tooth contour. The slide is slidably arranged on the plug. The slide is designed to carry out the plugging process between the plug and mating plug with a sliding movement. The third tooth contour is operatively connected or is operatively connected to the mating plug. The first tooth contour and the third tooth contour mesh with the second tooth contour. Provision is made for the second tooth contour to be designed as a gear, for the first tooth contour to be arranged on the slide, in particular stationary relative to the slide, and for the gear to be rotatably arranged on the plug.

[0017] Alternatively, it is provided that the second tooth contour is designed as a gear, that the first tooth contour is arranged on the plug, in particular stationary relative to the plug, and that the gear is arranged rotatably on the slide.

[0018] In these two alternatives, a displacement of the slider along the plug-in direction causes a displacement of the mating connector also along the plug-in direction and vice versa - i.e. a displacement of the slider and connector in the same direction.

[0019] Alternatively, it is provided that the third tooth contour is designed as a gear, in particular as a rotatable gear, wherein the first tooth contour is formed on the slide (or on the plug) and wherein the second tooth contour is formed on the plug (or on the slide).

[0020] In this third alternative, a displacement of the slider along the plug-in direction causes a displacement of the mating connector opposite to the plug-in direction and vice versa - i.e. an opposite displacement of the slider and the plug.

[0021] In principle, it is conceivable that the first two alternatives are implemented simultaneously. For example, on one side of the plug, a gear can be rotatably arranged as a second tooth contour and the first tooth contour on the slide, while on a further side (e.g. on the opposite side) of the plug, a (further) first tooth contour is formed and a (further gear) is rotatably arranged on the slide. On this further side, a (further) third tooth contour can additionally be arranged, which is operatively connected to the mating plug. The plug arrangement according to the invention has the advantage that the plug arrangement provides a low operating force, so that an operator or user only has to apply a low operating force (e.g. when plugging and unplugging) even with high plugging forces between the plug and mating plug, e.g. a maximum of 50N.Another advantage is that the cable outlet can be freely selected without coming into conflict with the operating element (here: the slider). This means that both a cable outlet parallel to the plug-in direction and a cable outlet rotated by 90° to the plug-in direction (angled plug) can be selected (generally: rotated from 0° to 90° to the plug-in direction) without having to adapt the operating mechanism. Another advantage is that the plug arrangement enables particularly simple, intuitive, quick and low-friction joining or plugging together and / or simple, intuitive, quick and low-friction disassembly of the plug and mating plug. A particularly simple plug-in movement is advantageously achieved.

[0022] Operating movement is enabled, in particular along the plug-in direction. Furthermore, the connector arrangement advantageously reduces the risk of the connector tilting relative to the mating connector when plugging or unplugging. This increases the service life of the connector and mating connector or of the contact elements arranged in the connector or of the mating contact elements arranged in the mating connector, and reduces the operating force. Furthermore, it can be advantageous that the connector arrangement only requires an extremely small amount of space when plugging or unplugging the connector and mating connector, in particular transversely to the plug-in direction. For example, the space requirement can be only slightly larger (e.g., at most 10% or at most 20%) than the so-called footprint of the connector along the plug-in direction.

[0023] The term “sliding movement” can be understood in particular as a movement of the slider relative to the plug.

[0024] For example, it can be provided that the sliding movement of the slider occurs parallel to the plug-in direction. This advantageously enables a particularly small footprint or installation space for the plug arrangement or the plug, or enables a particularly small space requirement for installation transverse to the plug-in direction. Furthermore, this advantageously enables optimal application of force, since the operating force constantly acts parallel to the plug-in direction (the force of an operator acts in the same direction as the closing movement or the closing movement).

[0025] Opening movement of the plug relative to the mating plug) and thus supports the plugging process.

[0026] Alternatively, the sliding movement of the slider can be arranged transversely to the plug-in direction. This advantageously reduces the space required by the plug assembly or the plug itself along the plug-in direction.

[0027] The plugging process can involve plugging together and / or unplugging.

[0028] The tooth arrangement is preferably a system comprising gears and racks. Such a gear preferably does not have a guide slot in which a projection of a counter element is guided.

[0029] For example, the connector can have a starting position (first position) and a final position (second position) relative to the mating connector. In the final position (second position), the connector is in mechanical and electrical contact with the mating connector.

[0030] The slider may, for example, have a first position and a second position relative to the plug.

[0031] It can be provided, for example, that by moving the slider relative to the plug from the first position to the second position, the plug is moved from the starting position (first position) with respect to the mating plug to the end position (second position) (e.g. when plugging together the plug and mating plug). Advantageously, by moving the slider relative to the plug from the second position to the first position, the plug is moved from the end position (second position) with respect to the mating plug to the starting position (first position) (e.g. when plugging apart the plug and mating plug). In other words, the plug arrangement has a mechanism for assisting the plugging process (reducing the operating forces) between a plug and a mating plug, in particular when a user performs a plugging process.In this case, a slider and at least one gear and / or at least one rack are arranged on the plug. In the case that at least one gear is arranged on the plug, this at least one gear is rotatably arranged on the plug.

[0032] In the case that at least one gear is arranged on the slide, this at least one gear is preferably arranged rotatably on the slide

[0033] Various configurations of the operative connection of the third tooth contour with the mating connector or with a component to which the mating connector is attached are conceivable. Possible embodiments of these configurations, which may be detachable without destruction, are described below purely as examples:

[0034] The (at least one) third tooth contour can, for example, be coupled or coupleable to the mating connector and / or to a component (e.g. a housing of a control unit) to which the mating connector is mounted. It can, for example, be firmly connected to the mating connector or to the component to which the mating connector is attached. Alternatively or additionally, the (at least one) third tooth contour is movably arranged on the connector and can be connected or coupled to the mating connector or the component (e.g. detachably without destruction). The expression “movably arranged on the connector” can be understood to mean, for example, that the third tooth contour is designed to be movable relative to a connector housing of the connector. It can, for example, be plugged over an outer contour of the connector or the connector housing in the manner of a sleeve or a collar. In this case, the connector has the third tooth contour.In principle, it is also conceivable that at least one of several third tooth contours is coupled or (fixedly) connected to the mating connector and can thus be assigned to the mating connector, and at least one of several third tooth contours is movably arranged on the connector and can thus be assigned to the connector. If the (at least one) third tooth contour is fixedly arranged on the mating connector or the component, it can be provided, for example, that the connector is first brought towards the mating connector until the third tooth contour comes into contact with the at least one second tooth contour. This position can, for example, be referred to as the starting position (first position) of the connector. The first tooth contour on the slide then meshes with the second tooth contour or is coupled to the second tooth contour or engages with it.If the slider is now moved from the first position to the second position, the connector moves from the initial position (first position) to the end position (second position). During this process, both the first tooth contour on the slider and the third tooth contour simultaneously engage or mesh with the second tooth contour.

[0035] If the third tooth contour or at least one of several third tooth contours is movably arranged on the plug or on the plug housing and can be connected or coupled to the mating plug or the component, it can be provided, for example, that the plug is moved towards the mating plug until this connectable or coupleable third tooth contour is in contact with the mating plug or the component and couples with it or connects with the mating plug. This position can, for example, be regarded as the starting position (first position) of the plug in the alternative or additional embodiment of the third tooth contour. The slide can then be moved from the first position into the second position. As a result, the plug is guided or displaced from the starting position (first position) towards the mating plug into the end position (second position).

[0036] It goes without saying that the unplugging process is reversed. In the last-described embodiment, it may be provided, merely as an example, that after reaching the starting position (first position), the third tooth contour can be removed from the mating connector (non-destructively) starting from the end position (second position).

[0037] In both embodiments, the movement of the slider and the first tooth contour in the plugging direction causes the at least one gear (second tooth contour or third tooth contour) to rotate. The at least one gear, in turn, engages the third tooth contour (or second tooth contour). Thus, when the slider moves (e.g., in the plugging direction (or opposite to the plugging direction)), the plug is pulled toward the mating connector by means of the at least one gear.

[0038] Preferably, the plug has (at least) one, in particular electrical, contact element, and the mating plug has (at least) one, in particular electrical, counter-contact element. The counter-contact element is configured to establish electrical contact with the electrical contact element. In principle, optical contact elements and optical counter-contact elements are also conceivable.

[0039] Preferably, the plug is moved from the starting position (first position) to the end position (second position) parallel to the plugging direction.

[0040] Preferably, the slider is moved from the first position to the second position along the plug-in direction.

[0041] The term “have” is used synonymously with the term “include” unless otherwise stated.

[0042] The subclaims show preferred developments of the invention.

[0043] In a further development, the connector assembly comprises an intermediate component. The third tooth contour is arranged on the intermediate component.

[0044] In one possible embodiment, the intermediate component is slidably or displaceably arranged on the plug or on a plug housing of the plug or is coupled to the plug or the plug housing. The intermediate component is connectable or connected to the mating plug and / or to a component to which the mating plug is fastened by means of a first connection, in particular by means of a first snap connection. In particular, the first connection can be released without destruction. This advantageously has the effect that both the first tooth contour and the third tooth contour and the second tooth contour are arranged on the plug. This allows the second tooth contour to be constantly engaged with the third tooth contour and prevents difficult contact between the third tooth contour and the second tooth contour. This embodiment thus enables simple handling and simple connection of the plug to the mating plug.In addition, this design advantageously avoids the mating connector having a very long or high and exposed element, which could be easily damaged.

[0045] It is understood that a component on which the mating connector is located (e.g., a housing of a control unit) is also considered to be associated with the mating connector. The case where the intermediate component couples to this component, to which the mating connector is attached, is thus encompassed by the wording of a coupling of the intermediate component to the mating connector. For reasons of readability, only the mating connector will be referred to below.

[0046] For example, it can be provided that the intermediate component is arranged captively on the plug or on the plug housing.

[0047] Alternatively or additionally, the intermediate component can be arranged on the mating connector before the plug is connected to the mating connector, or before the plug and mating connector are connected. The intermediate component can, for example, be formed as a single piece or integrally with the mating connector. Alternatively, the intermediate component can be connected to the mating connector, in particular in a non-destructively removable manner.

[0048] This advantageously results in the connector having fewer components and eliminating the need to route the intermediate component to the connector. This can have the advantage of making the connector easier to manufacture.

[0049] The provision of at least one intermediate component on the plug and at least one intermediate component on the mating plug can advantageously ensure that the plug can only be arranged in a defined orientation on the mating plug (Poka-Yoke).

[0050] In a further development, it is provided that the plug is designed to block the release of the operative connection between the third tooth contour and the mating plug in an end position (second position).

[0051] This has the advantageous effect - particularly in the event that the third tooth contour is provided on the plug and is coupled (only) during the plugging process with the mating connector or a component to which the mating connector is fastened - that the plug and mating connector can be plugged apart with reduced force by actuating the slider. If the operative connection between the third tooth contour and mating connector were to be released when plugged together, e.g. due to vibrations or other mechanical influences, actuating the slider (e.g. from the second position towards the first position) would possibly lead primarily to a displacement of the third tooth contour relative to the plug and / or the mating connector due to the high forces between the plug and mating connector and not to a displacement of the plug relative to the mating connector by means of the third tooth contour coupled to the mating connector.

[0052] In a further development, it is provided that the gear is rotationally symmetrical.

[0053] The rotation axis of the gear can only correspond, for example, to the symmetry axis of the gear.

[0054] This advantageously achieves uniform support along the sliding movement of the slider from the first position to the second position in the plug-in direction. Furthermore, this advantageously results in a particularly simple construction of the plug, connector, slider, and tooth arrangement, making production particularly cost-effective.

[0055] The force transmission (and thus the required travel of the slider from the first position to the second position) can be advantageously adjusted by selecting the gear diameter. The larger the gear diameter, the larger the lever arm that can be applied by the slider and, consequently, the greater the transmission ratio. Thus, for different connectors or different transmission ratio requirements, simply changing the gear diameter can be a simple way to meet the operating force requirements.

[0056] In the event that the gear is rotationally symmetrical, but the rotation axis of the gear lies outside the axis of symmetry, a variable transmission ratio along the plug-in path can be advantageously and easily enabled.

[0057] In a further development, it is provided that the gear is designed asymmetrically in a rotation plane.

[0058] The first tooth contour and the third tooth contour (or alternatively, in the third alternative described above, in which the third tooth contour is designed as a gear: the first tooth contour and the second tooth contour) can be designed, merely by way of example, to mesh with the second tooth contour (or, in the third alternative, with the third tooth contour) in the rotational plane over the predominant part (e.g., at least along 180°) of the circumference of the gear, in particular over substantially the entire circumference of the gear. In this case, substantially means an angular range of the second tooth contour (or, in the third alternative, the third tooth contour) between 315° and 360°.

[0059] This advantageously enables a transmission ratio that is variable along the plug-in path. In other words: a path-dependent transmission ratio is enabled depending on the plug-in forces that occur. This advantageously makes it possible, for example, to keep the operating force essentially or approximately constant along the plug-in path. This makes the plug-in process easier and safer and is also beneficial to the health of the operator. For example, at the beginning, with the force applied, a large plug-in path between the plug and mating plug can be created with a relatively short displacement of the slider, since at the beginning of the plug-in process, for example, only low plug-in forces are effective. As the process progresses, for example, towards the end of the plug-in process or in positions where high plug-in forces occur (e.g., opening peaks), a high force transmission can then be used. This means: A longer operating travel of the slider results in a slight displacement of the connector relative to the mating connector, but along this distance, the applied operating force translates into a greater insertion force. This is because, at the end of the insertion travel, all contacts are often engaged with the mating contacts. Furthermore, there are, for example, over-pressing ribs that must be pressed over.

[0060] It is understood that a gear can be designed to be both rotationally symmetrical and asymmetrical. This is the case, for example, when the gear has multiple planes (different from one another or spaced apart from one another along the direction of the rotational axis), where, for example, a first plane engages or meshes with the first tooth contour and a second plane engages or meshes with the third tooth contour (in the third alternative: with the third tooth contour). For example, the first plane can be designed to be rotationally symmetrical and the second plane asymmetrical, or vice versa.

[0061] In a further development, the gear comprises a first gear element and a second gear element. The first gear element and the second gear element are arranged offset from one another along a common rotational axis. In particular, the first gear element and the second gear element are fixedly connected to one another.

[0062] The first gear element meshes with the first tooth contour. The second gear element meshes with the third tooth contour (in the third alternative, in which the third tooth contour is designed as a gear, the second gear element meshes with the second tooth contour). This advantageously means that two different tooth contours can be realized with the same gear. This allows a freer or more targeted design of the transmission along the plug-in direction between the first position and the second position of the slider. This optimizes user support during the sliding movement. Another advantage is that the forces during the plug-in process are transferred to a thicker structure, making the plug assembly more robust and durable.

[0063] The first gear element and the second gear element can advantageously be designed, for example, as a single piece or as one piece (in particular with each other). They can be manufactured, for example, using the same injection-molding process, milling process, 3D printing process, or the like.

[0064] It can advantageously be provided, for example, that the first gear element and the second gear element are designed to be congruent. This can thus be a "thick gear": the upper part (e.g., first gear element) meshes with one tooth structure, the lower part (e.g., second gear element) with the other tooth structure – however, both parts (top / bottom) are designed identically ("congruent"). This can, for example, advantageously separate the planes of the tooth structures from each other, and wear on the gear teeth can be reduced (since the meshing occurs in different planes).

[0065] It can advantageously be provided, for example, that the offset of the first gear element and the second gear element corresponds to the thickness of the first rack and / or the second rack.

[0066] In a further development, the gearwheel has a first tooth contour section of the second tooth contour (in the third alternative: the third tooth contour) and a second tooth contour section of the second tooth contour (in the third alternative: the third tooth contour). The first tooth contour section meshes with the first tooth contour. The second tooth contour section meshes with the third tooth contour (in the third alternative, in which the third tooth contour is designed as a gearwheel, the second tooth contour section meshes with the second tooth contour). The first tooth contour section differs from the second tooth contour section.

[0067] This advantageously ensures that different support can be provided along a displacement path of the slide from the first position to the second position over the sliding path. This makes it easy to set a variable force transmission along the plug-in path. Furthermore, it is also advantageous to easily meet different geometric or stability-related requirements. For example, in the first alternative (in which the first tooth contour is arranged on the slide and the gear is rotatably arranged on the plug), the first tooth contour section interacting with the slide can have close teeth, which enables precise transmission of the slide path to the second tooth contour. The second tooth contour section interacting with the third tooth contour in this example, on the other hand, can have a coarse tooth contour with, for example,only one tooth or only two or three teeth (e.g., in the form of lever teeth). This can advantageously enable the transmission of large forces and prevent jamming. Furthermore, it minimizes the risk of an overly fine tooth contour being damaged by the high insertion forces. Similar considerations also apply to the second and third alternatives.

[0068] The first tooth contour section may, for example, differ from the second tooth contour section with regard to the tooth spacing and / or the tooth size and / or the tooth flank angle, etc.

[0069] For example, the first tooth contour section can extend in a circumferential range from 90° to 225°. The second tooth contour section can be located on the opposite side with respect to the rotational axis. It can, for example, extend in a circumferential range from 90° to 225°.

[0070] In a further development, it is provided that the first tooth contour, in particular at the point meshing with the second tooth contour, has a first distance from the rotational axis of the gear. The third tooth contour, in particular at the meshing point, has a second distance from the rotational axis of the gear (in the third alternative, in which the third tooth contour is designed as a gear, the second tooth contour, in particular at the meshing point, has a second distance from the rotational axis of the gear). The first tooth contour and the third tooth contour (or in the third alternative, the second tooth contour) are designed such that the ratio of the first distance to the second distance changes depending on the plug-in path.

[0071] This advantageously enables a variable force transmission along the plug-in path using simple and cost-effective means. This allows the operating force to be kept constant along the plug-in path, for example, and / or the operating path to be optimized (compared to a fixed transmission). It also advantageously enables particularly ergonomic operation. These considerations apply both to plugging and unplugging the plug and mating plug.

[0072] For example, it can be provided that the ratio of the first distance and the second distance at the beginning of the plugging process differs from the ratio of the first distance and the second distance at the end of the plugging process.

[0073] In other words: It is advantageously made possible that a movement of the slider by the user towards the mating connector, for example in a first section of the outward movement, leads to an accelerated movement of the plug towards the mating connector. This results in the plug being pulled towards the mating connector quickly. Furthermore, for example when the plug is already closer to the mating connector, a transmission is provided which, with little force being applied by the user to the slider, applies a particularly high torque or a particularly high force from the slider to the plug by means of the transmission. This supports the plug being pulled towards or brought closer to the mating connector (for example in mating sections where high mating forces are necessary) without requiring a greater effort from the user.Thus, this embodiment allows both an accelerated pulling of the plug towards the mating plug in a first section of the plugging path, as well as support of the approach of the plug to the mating plug by a high torque or a high force in a second section of the movement.

[0074] For example, it can be provided that before the plugging process, the first distance is shorter than the second distance and after the plugging process, the first distance is longer than the second distance, or that before the plugging process, the first distance is longer than the second distance and after the plugging process, the first distance is shorter than the second distance. In principle, it is conceivable that the ratio does not change continuously, but remains constant over certain sections of the path, and / or that the ratio initially increases (decreases) and then decreases (increases).

[0075] It can be provided, for example, that the gear is arranged in such a way that it meshes with the first tooth contour and with the third tooth contour (in the third alternative, in which the third tooth contour is designed as a gear: with the second tooth contour) along the entire displacement path in the plug-in direction.

[0076] In a further development, the plug has a plug housing and the mating plug has a mating plug housing. The slider is arranged on the plug housing, particularly parallel or perpendicular to the plugging direction, and is displaceable. The gear is arranged rotatably on the plug housing, on the slider, or on the intermediate element.

[0077] This advantageously ensures that the connector housing and the mating connector housing provide mechanical protection for the connector and the mating connector against external influences. Furthermore, the connector housing and the mating connector housing can simplify handling of the connector and the mating connector. Another advantage of the connector housing is that it enables well-defined guidance of the slider on the connector.

[0078] It can be provided, for example, that the (electrical) contact element can be or is arranged in the plug housing, in particular at a defined position. For example, at least one contact chamber can be provided in the plug housing, in which the contact element is or can be arranged. It can be provided, for example, that the (electrical) mating contact element can be or is arranged in the mating connector housing, in particular at a defined position. For example, at least one contact chamber can be provided in the mating connector housing, in which the mating contact element is or can be arranged.

[0079] The movement of the slider can, for example, result in a movement of the contact element relative to the counter contact element.

[0080] In a further development, it is provided that the plug can be connected to the mating plug by means of a snap connection or locking connection to secure the end position.

[0081] This advantageously prevents the connection between the plug and the mating plug from becoming accidentally loose.

[0082] For example, it can be provided that the plug and the mating plug are detachably connected to one another in a non-destructive manner, particularly in the second position (end position). For example, the plug and the mating plug can be detachably connected to one another in a non-destructive manner by means of a locking connection or a snap connection.

[0100] In the exemplary embodiments described below, it is always provided by way of example that the first tooth contour 21a is arranged on the slide 21, that the second tooth contour 23a, 24a is designed as a gear 23, 24 and that the gear 23, 24 is rotatably arranged on the plug 20.

[0101] It is understood that there may also be other alternative embodiments - not shown here, but easily deducible from the figures shown - some of which have already been described above.

[0102] This includes, for example, an embodiment (not shown here) in which the second tooth contour is designed as a gear, and in which the first tooth contour is arranged, in particular in a fixed position, on the plug or on the plug housing, and in which the gear is rotatably arranged on the slide, in particular in a fixed position on the slide. Preferably, the gear is formed between the first tooth contour and the third tooth contour.

[0103] In a further embodiment (not shown here), the third tooth contour is designed as a gear, the first tooth contour is formed on the slide, and the second tooth contour is formed on the plug. Preferably, the gear is formed between the first tooth contour and the second tooth contour.

[0104] In the embodiment shown in Figs. 1 and 2, two gears 23, 24 are provided by way of example, although embodiments with exactly one second tooth contour 23a, 24a or with more than two second tooth contours 23a, 24a are also conceivable. The plug 20 can have a first position or initial position S1 (see Fig. 1) and a second position or end position S3 (see Fig. 2) relative to the mating plug 30. The plug 20 can be displaced between the two positions S1, S3 relative to the mating plug 30.

[0105] The plug 20 here, for example, has a plug housing 29. The mating plug 30 here, for example, has a mating plug housing 31. The slider 21 is arranged, for example, displaceably on the plug housing 29, in particular parallel or perpendicular to the plugging direction 100. The gear 23, 24 is arranged, for example, rotatably on the plug housing 29.

[0106] The plug 20 has, for example, at least one electrical contact element (not shown here). The mating plug 30 has, for example, at least one electrical counter-contact element (not shown here). The at least one electrical counter-contact element is configured to establish electrical contact with the at least one electrical contact element.

[0107] The slider 21 is displaceable or slidable relative to the plug 10 between a first position P1 (see Fig. 1) and a second position P2 (see Fig. 2). In Fig. 1, the slider 21 is in the first position P1. The plug 20 is in the starting position S1, which can also be referred to as the first position. The first tooth contour 21a and the third tooth contour 22a mesh with the second tooth contour 23a, 24a. Here, the left first tooth contour 21 in Fig. 1 on the one hand and the left third tooth contour 22a on the other hand are in engagement with the left second tooth contour 23a and the right first tooth contour 21 and the right third tooth contour 22a are in engagement with the right second tooth contour 24a and mesh with it.

[0108] A displacement of the slider 21 from the first position P1 (see Fig. 1) to the second position P2 (see Fig. 2) along the plugging direction 100 leads to a displacement of the plug 20 from the starting position S1 or the first position to the end position S3 or the second position. This corresponds to a mating of the plug 10 and the mating plug 30. The end position S3 or second position of the plug 20 is shown in Fig. 2. A displacement of the slider 21 from the second position P2 counter to the plugging direction 100 to the first position P1 leads to a displacement of the plug 20 from the end position S3 or the second position to the starting position S1 or the first position. This corresponds to a separation of the connector 10 and the mating connector 30. As already described above, the intermediate component 22 is arranged on the mating connector 30 merely as an example - before the connector 20 is connected to the mating connector 30.

[0109] A Cartesian coordinate system is shown in all figures. The plug-in direction 100 corresponds to a first direction (in all figures, the plug-in direction 100 runs from top to bottom, for example). A second direction 200 runs perpendicular to the plug-in direction 100, and a third direction 300 runs perpendicular to the plug-in direction 100 and perpendicular to the second direction 200.

[0110] In Figs. 1 and 2, the two gears 23, 24 are designed to be rotationally symmetrical, for example. A rotation axis 23b, 24b of the respective gear 23, 24 corresponds, for example, to the respective axis of symmetry of the gear 23, 24. The rotation axis 23b, 24b extends in the third direction 300.

[0111] The connector assembly 10 here has, for example, an intermediate component 22. The third tooth contour 22 is arranged or formed on the intermediate component 22 merely by way of example. Here, it is arranged, for example, in the manner of a rack. A third tooth contour 22 is formed on each of the two longitudinal sides of the intermediate component 22. The two gears 23, 24, each of which has the second tooth contour 23a, 24a or each of which represents a second tooth contour 23a, 24a, are arranged, for example, on both sides of the intermediate component 22.

[0112] The operative connection between the mating connector 30 and the third tooth contour 22a is achieved here, for example, by the intermediate component 22. The intermediate component 22 can be designed, for example, as an injection-molded part or as a stamped and bent part. It can be designed, for example, to be inherently rigid and / or torsionally rigid, in particular such that it can transmit forces and does not twist or bend, or only slightly, when force is applied by the second tooth contour 23a, 24a.

[0113] Here, the intermediate component 22 is connected to the mating connector 30 merely by way of example. The operative connection is established. This can be achieved, for example, by means of a (first) connection. The (first) connection is embodied here, for example, as a first snap connection 26. The (first) connection is embodied here, for example, such that the intermediate component 22 is detachably connected to the mating connector 30 in a non-destructive manner.

[0114] The intermediate component 22 can, for example, be arranged on the mating connector 30 before the connector 10 is connected or plugged together with the mating connector 30 (this is the case here by way of example). Alternatively (or additionally, in the case of multiple intermediate components 22), it can also be provided that the intermediate component 22 (or at least one of multiple intermediate components 22) is already arranged on the connector 10 or on the connector housing 29 before plugging together (in particular displaceable relative to the connector 10 or to the connector housing 29, particularly preferably captively and displaceable relative to the connector 20 or to the connector housing 29).

[0115] Figure 2 shows the connector assembly 10 according to the first embodiment. The connector 20 is in the end position S3 or second position, and the slider 21 is in the second position P2. In the end position S3 or second position, the connector 20 is in mechanical and electrical contact with the mating connector 30.

[0116] In the end position S3 or second position, a locking connection 32 is provided here merely by way of example between the plug 20 and the mating connector 30, or the plug 20 is connected to the mating connector 30 by means of a locking connection 32, in particular connected in a non-destructively releasable manner, to secure the end position S3. In this case, a locking hook or clip hook or snap hook is arranged on the slide 21, which is locked to an undercut on the mating connector 30. The locking connection 32 makes it difficult to pull the slide 21 off the mating connector 30, in particular from a mating connector housing 31. This reduces the risk of the established plug connection being inadvertently released.

[0117] Figure 3a shows a highly schematic view of a connector arrangement 10.

[0118] Two cables 40 are shown as an example on the plug 20. In a first option, a first cable outlet 51 is shown as a straight cable outlet or 180° cable outlet (solid lines), whereby the cables 40 leave the plug 20 or the plug housing 29 approximately parallel to the plugging direction 100. In a second, alternative option, a second cable outlet 52 is provided. This second cable outlet 52 is designed as an angled cable outlet, e.g. rotated by 90° to the plugging direction 100, although other directions are also conceivable (the second cable outlet 52 is shown with dashed lines). The slide 21 can be moved independently of the cable outlet 51, 52, here for example parallel to the plugging direction 100, between the first position P1 (see Fig. 3a) and the second position P2 (see Fig. 3b) relative to the plug 20 or the plug housing 29.

[0119] Here, for example, the third tooth contour 22 is arranged on an intermediate component 22, as in Figs. 1 and 2. The intermediate component 22 is arranged displaceably, in particular captively, on the connector 20 or displaceably relative to the connector 20 or displaceably relative to the connector housing 29. The intermediate component 22 is connected to the mating connector 30; here, the (first) connection is designed, for example, as a, in particular first, (non-destructively releasable) snap connection 26.

[0120] In Fig. 3a, the connector assembly 10 is in a snap position S2 or snap position. The snap position S2 or snap position can correspond to the starting position S1 or the first position. In the snap position S2 or snap position, the connector 20 with the intermediate component 22 and the mating connector 30 are connected to one another via the (first) snap connection 26. The highly schematically illustrated slide 21 is - as already described above - in the first position P1. If the slide 21 is now moved from the first position (see Fig. 3a) to the second position P2 (see Fig. 3b), the connector 20 together with the connector housing 29 is moved from the starting position S1 to the end position S3, relative to the mating connector 30 or the mating connector housing 31, i.e. along the plug-in direction 100 (here: downwards).

[0121] Figure 3b shows the connector assembly 10 from Figure 3a. The slider 21 is displaced relative to the connector 20 or the connector housing 29—here, for example, parallel to the plugging direction 100—into its second position P2. The connector 20 is in the end position S3 or the second position. In the end position S3 or the second position, an electrical contact is established between the connector 20 and the mating connector 30. In the end position S3 or the second position, the release of the operative connection between the third tooth contour 22a and the mating connector 30 is blocked.

[0122] The operative connection between the third tooth contour 22a and the mating connector 30 is established here by the connection between the intermediate element 22 and the mating connector 30 and is formed here by the (first) snap connection 26. This (first) snap connection 26 can, for example, only be opened by displacing the snap hook or locking hook or clip inwards (i.e., towards the connector housing 29), since otherwise the snap hook cannot be unlocked from the undercut. If the connector is now in the second position or end position S3 (see Fig. 3b), the snap hook or the intermediate component 22 can no longer be displaced inwards (here, for example, parallel to the second direction 200), since it is blocked from this displacement by the connector 20 or the connector housing 29, for example.

[0123] In other words: Here, for example, a release of the (first) snap connection 26 between the intermediate component 22 and the mating connector 30 is blocked by the connector 20, in particular by the connector housing 29.

[0124] Figure 4 shows a connector assembly 10 in the initial position S1, which here corresponds, for example, to the snap-in position S2 or snap-in position. The gear 23, 24 is designed asymmetrically in the rotation plane 100, 200, for example.

[0125] The first tooth contour 21a and the third tooth contour 22a are designed here merely as an example to mesh with the second tooth contour 23a, 24a over the majority of the circumference of the gear 23, 24, in particular over substantially the entire circumference of the gear 23, 24 in the rotation plane 100, 200. "Substantially the entire circumference" can mean, for example, an angular range of 315° to 360° of the second tooth contours 23a, 24a.

[0126] The plug 20 has the plug housing 29 and the mating plug 30 has the mating plug housing 31. The slider 21 is arranged here merely by way of example on the plug housing 29 so as to be displaceable parallel to the plugging direction 100. Alternatively, the slider 21 is arranged on the plug housing 29 so as to be displaceable orthogonally or in another angled direction to the plugging direction 100 (not shown here). Furthermore, an intermediate component 22 is arranged on the plug housing 29, which here has the third tooth contour 22a and which can enter into a (releasable) operative connection with the mating plug 30 by means of the first snap connection 26. The plug encloses a mating plug collar (without reference symbol) of the mating plug 30 with a plug collar (without reference symbol) arranged at the lower end of the plug housing 29 in Fig. 4. The plug 20 is thus designed as an external plug which accommodates the mating plug collar.The slider 21 lies outside the intermediate component 22 when viewed in a radial direction perpendicular to the plugging direction 100. In other words, the slider 21 can be displaced outside the plug housing 29 and outside the intermediate element 22 in the region of the third tooth contour 22a relative to the plug 20 and relative to the intermediate component 22.

[0127] The slider 21 is designed here, for example, in the form of a sleeve, a cuff, or a collar that can be displaced along the connector housing 29 or along the connector 20. The slider 21 can be guided on the connector 20 or on the connector housing 29, in particular by means of a guide structure.

[0128] The at least one gear 23, 24 (here: two gears 23, 24 as in Figs. 1, 2) is rotatably mounted on the connector housing 29. The connector housing 29 is configured to block the release of the operative connection between the third tooth contour 22a and the mating connector 30 (here, for example, established by the first snap connection 26) in the end position S3.

[0129] In the first position P1 shown in Fig. 4, the second tooth contour 23a, 24a has a first distance 27 from the first tooth contour 21, starting from the respective rotation axis 23b, 24b, and a second distance 28 from the third tooth contour 22a, starting from the respective rotation axis 23b, 24b. Due to the asymmetry of the at least one gear 23, 24 and due to the design or shape of the first tooth contour 21a and the third tooth contour 22a, the first distance 27 and the second distance 28 differ in the first position P1 shown here for the shape of the gears 23, 24 shown here.

[0130] If the slider 21 is now displaced in the direction of the second position P2 (here, for example, parallel to the plug-in direction 100, although in other embodiments a different displacement direction, e.g. perpendicular or otherwise angled to the plug-in direction 100 is also conceivable), the ratio of the first distance 27 and the second distance 28 changes depending on the plug-in path of the plug 20 or depending on the displacement path of the slider 21. This results in different transmission ratios or different lever arms along the plug-in path of the plug 20, whereby the operating force on the slider can be adjusted as required, e.g. can be evened out: with low plug-in forces, a long plug-in path of the plug 20 can be achieved with a small displacement path of the slider 21, for example, with a reasonable amount of force from an operator. If, on the other hand, the plug-in forces are increased (e.g.when opening peaks occur or at the end of the plugging process, when the mechanical resistances between the contact elements and mating contact elements and / or between the plug housing 29 and the mating plug housing 31 are particularly high), the transmission can be designed in such a way that the greatest possible force transmission occurs: a high travel of the slide 21 only causes a small plugging travel of the plug 20, but the operating force remains low.

[0131] Here, for example, it is provided that the ratio of the first distance 27 and the second distance 28 at the beginning of the plugging process differs from the ratio at the end of the plugging process.

[0132] It is understood that other shapes or contours or contour profiles of the first tooth contour 21a, the second tooth contour 23a, 23b and the third tooth contour 22a can also be provided.

[0133] Figure 5 shows a schematic detailed view of a plug assembly 10 in a first position P1 of the slider 210—essentially a tooth arrangement 25 of a plug assembly 10 is shown. The gear 23 has a first gear element 23c and a second gear element 23d. The first gear element 23c and the second gear element 23d are offset from one another along a common rotation axis 23b and are fixedly arranged relative to one another. The first gear element 23c meshes with the first tooth contour 21a, and the second gear element 23d meshes with the third tooth contour 22a. The rotation axis 23b extends here, for example, along a third direction 300.

[0134] The first tooth contour 21a has a first distance 27 at a meshing point with the rotational axis 23b, 24b of the gear 23, 24, and the third tooth contour 22a has a second distance 28 at the meshing point with the rotational axis 23b, 24b of the gear 23, 24. The first tooth contour 21a and the third tooth contour 22a (together with the second tooth contour 23a, 24a) are designed such that the ratio of the first distance 27 and the second distance 28 changes depending on the insertion path, and in particular the ratio of the first distance 27 and the second distance 28 at the beginning of the insertion process differs from the ratio at the end of the insertion process. Here, for example, it is provided that before the plugging process, the first distance 27 is smaller than the second distance 28 and after the plugging process, the first distance 27 is greater than the second distance 28. In principle, an embodiment is also conceivable in which, for example,before the plugging process, the first distance 27 is greater than the second distance 28 and after the plugging process, the first distance 27 is smaller than the second distance 28.

[0135] The gear 23, 24 is designed such that it meshes with the first tooth contour 21a and the second tooth contour 22a along the entire displacement path in the insertion direction 10. Thus, the first distance 27 in the first position P1 of the slider 21 is longer than the second distance 28.

[0136] This advantageously enables a transmission ratio that can be varied along the plug-in path, as in the plug arrangement of Fig. 4, as will be seen further below in connection with Fig. 6.

[0137] By arranging the gear elements 23c, 23d in different planes, a large gear ratio change can be made possible particularly easily, since the first tooth contour 21a and the third tooth contour 22a no longer have to be in the same plane and thus different first and second distances 27, 28 can be realized in a small space, without, for example,

[0138] Slider 21 and intermediate component 22 (or generally: first and third tooth contour 21a, 22a) come into conflict (mechanical contact) with each other.

[0139] Figure 6 shows the detailed view from Fig. 5 in a second position P2 of the slider 21.

[0140] The second distance 28 is now smaller than the first distance 27. The ratio of the first distance 27 to the second distance 28 has thus changed along the plug-in path of the plug 20 or along the displacement path of the slide 21.

[0141] Figure 7 shows a schematic view of a plug assembly 10 - the focus of Fig. 7 is on the tooth arrangement 25 of the plug assembly 10. The plug assembly 10 has an intermediate component 22, wherein the third tooth contour 22a is arranged on the intermediate component 22. The intermediate component 22 is here, for example, already arranged on the mating connector (30) before the plug 20 and mating connector 30 are plugged together. The intermediate component 22 is here, for example, formed in one piece or in one piece with the mating connector 30 or with the mating connector housing 31. Here, for example, it is not formed in a way that can be removed non-destructively from the mating connector 30 or the mating connector housing 31. It can, for example, be manufactured with the mating connector 30 or the mating connector housing 31 in a common manufacturing process (e.g., an (injection) molding process, a 3D printing process, etc.).

[0142] The gear 23, 24 has a first tooth contour section 23e of the second tooth contour 23a and a second tooth contour section 23f of the second tooth contour 23a. The first tooth contour section 23e meshes with the first tooth contour 21a, and the second tooth contour section 23f meshes with the third tooth contour 22a. The first tooth contour section 23e and the second tooth contour section 23f differ from each other.

[0143] In the right hemisphere of gear 23 (shown in Fig. 7), a tooth structure with a plurality of closely spaced and, for example, relatively fine teeth is formed. In the right hemisphere, only a single, and, for example, quite coarse (lever) tooth is provided.

[0144] The third tooth contour 22a, for example, is very coarse or coarsely segmented compared to the first tooth contour 21a. The third tooth contour 22a has only a first (upper) projection, a recess below it, and again a second (lower) projection. Furthermore, only the single (lever) tooth protruding from the gear disk, as described above, is provided as the second tooth contour section 23f. This allows particularly high forces to be transmitted without the risk of jamming.

[0145] Figure 8 shows a schematic detailed view of a plug assembly 10—essentially depicting a tooth arrangement 25 of a plug assembly 10. The embodiment depicted in Fig. 8 differs from that in Fig. 7 in that the first tooth contour 21a is not parallel to the plugging direction 100. Furthermore, the individual teeth of the second tooth contour 23a have different sections relative to the rotation axis 23b.

[0146] Preferably, the tooth contour 21a runs along a straight line and has an angle greater than zero to the insertion direction 100. In other embodiments, the tooth contour 21a can have a curved profile.

[0147] The embodiment of Fig. 8 effects a variable transmission ratio along the plug-in path of the plug 20 or along the displacement path of the slide 21.

[0148] It is understood that for all embodiments, the slider 21 and / or the connector housing 29 and / or the mating connector housing 31 and / or the tooth contours 21a, 22a, 23a and / or the intermediate component 22 can comprise a material, in particular predominantly, which is selected from the group: a plastic (in particular glass fiber-filled or non-glass fiber-filled polyamide (PA), polybutylene terephthalate (PBT), polyethylene (PE), etc.), a metal (in particular aluminum, iron, etc.).
