Description

Title of the invention: Connector and connector device STATE OF THE ART

[0001] The present invention relates to a modular connector for connection to a complementary connector and to a connection device comprising a connector and a complementary connector.

[0002] Connection devices typically comprise a connector and a complementary connector. A connection is established when the connector and complementary connector are assembled, for example, by engaging one another along an axis or in a specific direction of engagement or insertion. Applications for such connectors include, for example, the automotive sector for connecting various components, control devices, or wiring harnesses. Connector assembly often still involves significant manual intervention. Due to the complexity of wiring harnesses, automation is desirable. Improving the automation capabilities would also be desirable.

[0003] Document DE 10 2011 006 195 Al describes a modular electrical connection device according to which several connection modules are first installed relative to each other in a module support and then connected by an assembly process, in a manner fixed to the module support.

[0004] DESCRIPTION AND ADVANTAGES OF THE INVENTION

[0005] The modular connector according to the invention is a modularly constructed connector for connection to a complementary connector, comprising:

[0006] - a housing with a set of cup-shaped connection slots, each connection point is defined by an enclosing wall device.

[0007] - at least one connection module that is in a connection slot and that is designed specifically to securely receive at least one connection element, preferably several connection elements, and

[0008] - a mechanical coding device made between each connection point and each engaged connection module, to have a defined association between the connection module and the connection location,

[0009] - the mechanical coding device having a first coding element and a second complementary coding element to the first coding element,

[0010] - the first coding element being provided at the connection location in the form of the bucket and the second coding element being on the connection module, and

[0011] - each first and second complementary coding element are different and / or are at another position at the connection location.

[0012] This device has the advantage of allowing the automated assembly of the connector with the connection modules. This offers high cost potential and considerably simplifies connector manufacturing. A wide variety of connection modules equipped with a wide variety of connection elements can be used. This allows for simple, quick, and flexible adaptation of the connector equipment according to different types of complementary connectors or connection elements. Each connection module can—in other words—be equipped with different connection elements (or at least one connection element) depending on the type of complementary connector. The modular design allows the connection modules to be placed manually or automatically in the connector, i.e., in its housing.

[0013] This is achieved, according to the invention, in that the modular connector has a housing with a set of connection slots, preferably cup-shaped. The connection slots are defined respectively by an enclosing wall device. The connector further has at least one connection module installed at a connection slot and designed, in particular, to securely receive at least one connection element. Preferably, several connection elements are contained within a connection module. In addition, the connector according to the invention has a mechanical coding device located between each connection slot and each engaged connection module to ensure a defined association between the connection module and the connection slot. The mechanical coding device comprises a first coding element and a second coding element complementary to the first.The first coding element is fitted to the cup-shaped connection location, and the second coding element is fitted to the connection module. Thus, each first and second coding element, complementary to this one, for each connection location or each connection module can be different and / or be installed in a different position within a connection location or connection module.

[0014] The expression "another position" means that at least a part of the mechanical coding device or of the first / second coding element differs from all other coding devices, i.e. first and / or second coding elements at the position.

[0015] In other words:

[0016] A single connection module can therefore only be used at a single connection location. Thus, in the case of a housing with a defined number of connection locations, it is necessary, for each connection location, Its own connection module, which is itself preferably replenished each time with at least one connection element, preferably several connection elements. If, for example, there are nine connection slots, nine different first coding elements or first coding means are provided, and correspondingly, there will be nine different types of connection modules, each with complementary second coding elements; that is, second coding means are required. Each type of connection module can only engage correctly in a single connection slot. The different connection modules may be all or some identical (with the same connection elements) or may be replenished with different connection elements.

[0017] Surprisingly, while individual coding of the connection locations and their respective connection modules does increase the number of different types of connection modules (each connection location requires its own type of connection module with, respectively, secondary coding methods, thus increasing the number of variants), this implementation has the advantage of simplifying the automation of equipping the connection locations and connection modules with connecting elements. Furthermore, it reduces the risk of installation errors, even with a large number of variants on an assembly line.Indeed, the configuration of connection modules with connection elements can be flexibly adapted to each customer's requirements and advantageously avoid any incorrect exchange or positioning of the various connection modules in the wrong connection locations thanks to the first and second coding elements or coding means.

[0018] The coding device may have a single first coding element for each connection location. However, it is also possible to have a set of first coding elements for a coding location, for example, for a defined geometry layout, such as width, length and / or height, or other such characteristics.

[0019] Surprisingly, despite the very wide variety of connection element variants for a piece of equipment, different configurations, or even any configuration, can be achieved within the housing, i.e., the connector housing, without the need to develop and implement a connection system specific to each customer request. Moreover, it is possible, for example, with slightly different connector housings, to meet the majority of customer requirements regarding the number of connection elements and functionality. Furthermore, the customer can install or predefine the desired connection elements in the connection modules for assembly. In other words, the customer can, Simply put, the connector can be individually adapted, according to the construction box or modular principle, from the housing and the connection modules that equip it; the connection modules can be individually equipped with the connection elements. Because the connection modules can be easily equipped, and because the few types of housings (for example, for different numbers of connection modules) are known and confirmed and easily adaptable to the complementary connector housing, this significantly reduces development time compared to developing a connector individually for customers.

[0020] Furthermore, and advantageously, the manufacturing time or the equipment required for the connectors is considerably reduced. Thus, instead of equipping each connector housing with a set of connection elements (for example, more than one hundred connection elements) individually and especially manually, the equipment allows the connection modules to be pre-filled according to the customer's requirements. These connection modules can be equipped, for example, with one to 50, and preferably one to 26, connection elements. Such a number of connection elements is well suited to the equipment, in a simple and quick manner, and in particular, in an automated way. Then, the pre-equipped connection modules can simply be placed in the housing (connector). This operation can be easily automated.In other words: instead of manually equipping the housing (connector) with connection elements, this assembly operation can be automated by first equipping the connection modules with connection elements, and then equipping the housing with the connection modules. The initial coding elements ensure that the pre-equipped connection modules are mounted in the correct location.

[0021] The mechanical coding device can be implemented at the connection point using different coding elements and / or different positions. The connector is suitable for both electrical and optical connections. A connection element may, for example, be selected from the group comprising electrical contact elements or optical elements (transmitting elements, receiving elements, optical or analog coupling elements) or even sensor elements or analog elements.

[0022] The wall device can, for example, be in the form of a wall that surrounds the connection location, for example, a closed, enveloping wall.

[0023] The connection module is preferably at least one chamber and preferably a set of chambers in which at least one connection element can be installed. This allows for the inclusion, within a connection module, of chambers of different sizes, or chambers of the same size.

[0024] The connecting element is preferably attached, or can be attached, in a primary manner in the chamber by means of a primary locking device to prevent loss (for example, against extraction or ejection in the direction opposite to the direction of engagement). Such primary attachment is achieved, for example, by a reversibly movable elastic element on the connecting element (for example, a latching lance that moves transversely to the direction of engagement) and that can attach to an undercut in the chamber of the connecting module or penetrate it. The reverse embodiment is also possible (a latching lance fitted to the chamber, and this latching lance attaches to an undercut of the connecting element).

[0025] In addition, in each connection module other connection elements can be installed and for each connection location connection modules can be used equipped in any way.

[0026] The connection module of the connection location can be made according to the complementary connector and / or the application to receive different connection elements and / or a different type of connection elements.

[0027] The connection locations (e.g., cup-shaped) may be provided or installed in a matrix arrangement within the housing. The matrix arrangement may have, for example, at least two columns and at least two rows (2x2 matrices). It may have, for example, three columns and two rows (3x2 matrices) or, for example, three columns and three rows (3x3 matrices), or more columns and / or rows. However, in principle, a matrix arrangement with one row or one column, or housings, may be possible, for example, a 2x1 matrix or a 3x1 matrix, etc. In principle, a 1x1 matrix may even be possible.

[0028] The housing with all the connection points (for example, cup-shaped) can be made, for example, in one piece, i.e., it can be made monolithically in one piece so that it cannot be decomposed into smaller units without being destroyed. For example, if a housing with a different matrix arrangement is required (for example, instead of a 3x1 matrix, a 3x2 matrix), it can be provided that only a second 3x1 matrix is ​​coupled to the first 3x1 matrix, for example, by a connecting element. Moreover, it is then preferable to provide a separate housing as a 3x2 matrix.

[0029] The housing can be manufactured by an injection molding process. It can be, for example, made of plastic.

[0030] Advantageously, the connection modules have different shades or colors depending on the connection location to which they are associated, or depending on the coding device, or depending on the type of the second coding element. Thus, the user or operator can easily recognize which The connection module must be installed at the connection point. A particularly advantageous feature is that a different color is used for each connection point. This color coding allows for the simple and reliable automatic assembly of the housing with the connection modules. For example, the colors can be applied during injection molding using different colors of the material, such as plastic. This enables simple and cost-effective production of the connection modules. Furthermore, the color coding, and thus the nature or type of the connection module, is recognizable from all directions, allowing for particularly simple and reliable automated assembly of the housing with the connection modules.

[0031] The expression "including" in this description is synonymous with the expression "having" unless otherwise indicated.

[0032] Preferably, the cup-shaped connection slots of the connection module all have the same cross-section, i.e., the same external dimensions. In particular, the housing thus allows for the creation of a connection matrix with connection slots of the same cross-section or the same external dimensions. This offers the advantage of equipping connection slots with connection modules in a particularly simple and potentially automated manner. Furthermore, and advantageously, this method allows for equipping the connection modules with connection elements in a particularly simple and potentially automated manner, for example, using an automated equipment system equipped with a gripper that always applies a similar or identical gripping range or reach length, thereby reducing the risk of errors and shortening the production rate.Furthermore, this method advantageously optimizes the mechanical stability of the housing because the cross-section is chosen so that, for example, in the case of an injection molding process, the housing undergoes minimal deformation. Additionally, the same cross-section makes manufacturing the connection modules particularly simple and economical. For example, the same injection mold can be used to easily produce the second coding elements for each type of connection module, for instance, using movable elements within the injection mold.

[0033] The connecting modules may have the same cross-section or the same external dimensions, or identical external dimensions. The cross-section or external dimension or external dimensions of the different connecting modules allow for different configurations of room layouts using the connecting elements. For example, each connecting module may have two different types of rooms, different numbers of rooms, and different room layouts. The user can thus, for a defined connection location, choose a corresponding connection module with a different occupation in connection elements.

[0034] The cup-shaped connection locations are essentially in the form of rectangular parallelepipeds, all of whose sections are identical.

[0035] The rectangular parallelepiped shape advantageously allows for very simple integration into an automated equipment. Furthermore, it offers the advantage of a particularly compact housing design.

[0036] Minor variations from the ideal rectangular parallelepiped shape correspond, for example, to rounded corners and / or a mechanical anti-rotation device. This prevents, for example, the incorrect insertion of a connection module into a connection slot by 180° or 90°, right from the start of the insertion process (similar to the anti-rotation protection of a SIM card thanks to a single cut corner).

[0037] The corresponding connection modules can also have a shape that is practically rectangular. They can, for example, all have the same cross-sectional size or the same external dimensions. This facilitates the handling of the connection modules, for example, manually or with an automated equipment.

[0038] According to another preferred embodiment of the invention, the first coding element is installed at the connection location only in a bottom area oriented towards the complementary connector for the cup-shaped connection location. Each wall of the cup-shaped connection location's wall assembly is made, for the remaining wall portion or wall area outside the bottom area, without a coding element. Thus, (with the exception of the bottom area) the connection location will have smooth walls, which considerably simplifies, in particular, the engagement phase of a connection module in a cup-shaped connection location. The walls of the connection location do not include a coding element and, preferably, do not include any other engagement elements.Furthermore, and advantageously, this simplifies the manufacture of the connector or the wall device for the connection location. Another advantage is that this method also allows for the inclusion of other functional elements on the connection module (e.g., a movable secondary locking element) without interfering with the operation of a coding rib that runs the entire length of the wall or is geometrically complex.

[0039] The bottom zone extends, for example, to a maximum height of 35% or a maximum of 25% and preferably a maximum of 20% and, in a particularly preferential manner, a maximum of 15% and in an extremely preferential, up to a maximum of 10% of the respective wall height. The wall height is measured, for example, parallel to the direction of engagement of the connection module at the respective connection location.

[0040] According to another advantageous feature, the bottom area of ​​the connection location has an opening and a virtually peripheral inner flange, the first coding element being provided on, or respectively, within the inner flange. The inner flange thus preferably covers an internal surface area of ​​10% of the cross-section of the bottom area of ​​the connection location. The first coding elements may be provided, for example, exclusively on the walls, directly adjacent to the inner flange. Other wall areas, particularly those beyond the inner flange, may, for example, not have any first mechanical coding elements.

[0041] The inner collar is, for example, briefly interrupted at one or more places, for example, over less than 10% of the developed length, for example, for manufacturing reasons.

[0042] The inner flange advantageously provides an axial stop for a connection module engaged in the connection slot, preventing the connection module from being pushed too deeply into the slot. Furthermore, and advantageously, the inner flange provides a more robust coding element. The opening has the advantage of constituting at least one additional connection element for the supplementary connector to be coupled or linked to the connection element of the connection module.

[0043] The first coding element is, for example, connected to the collar and / or the wall or the wall assembly. It can, for example, be made in one piece with the collar and / or the wall or the wall assembly.

[0044] According to another advantageous feature, to ensure the connection operation between the connector and the complementary connector, between adjacent cup-shaped connection locations, an engagement aid device is provided. The engagement aid device is designed to guide and simplify the connection phase between the connector and the complementary connector. In this way, the risk of jamming between the connector and the complementary connector is reduced, for example. It also reduces the risk of damage to the connector and complementary connector during assembly.

[0045] The engagement aid device preferably has at least one recess or includes such a recess for receiving a blade or blade-shaped element of a complementary connector. At least this recess (in particular, all the recesses) has a cross-section smaller than the cross-section of the connection locations. This recess is preferably slot-shaped. In a particularly Preferably, there are several engagement aids between the connector and the complementary connector. In a particularly preferential manner, between directly adjacent connection locations, there are recesses for the engagement aid.

[0046] According to another feature, at least one recess is formed continuously, not in the form of a channel, from the lower side of the housing to the upper side. This recess can be formed, in particular, in the direction of the complementary connector in the form of a pocket. This prevents the penetration of fluid through the recess in the direction of the complementary connector. An intermediate bottom is provided in at least one recess. In this way, at least one recess is open only on one side in the direction of the complementary connector. Such an intermediate bottom also increases, for example, the stability of the recess so that the walls of the recess can be made with less thickness. Above the intermediate bottom, there is at least one recess extending further upwards and open. In this way, deformation is reduced, for example, during the manufacturing of the housing by injection molding.

[0047] For precise positioning of the connection module at the connection location, the connector preferably also has at least one alignment device between each connection location and each engaged connection module. The alignment device is designed to ensure the final engagement position of the engagement module in a bucket-shaped location (for example, a directional x- / y- position, i.e., transverse to the engagement direction). The alignment device preferably includes at least one first alignment element at the bucket-shaped connection location and (at least) one second alignment element on the connection module.

[0048] The tolerance or tolerance measurement of the alignment device is preferably less than the tolerance of the mechanical coding device. Furthermore, preferably, the tolerances of the alignment elements are at least 20% less than the tolerance of the coding elements, and in particular, preferably at least 10% less. The tolerances relate to both the position and the dimensions, i.e., the width and / or length and / or height of the respective alignment elements. The alignment elements offer the advantage of mechanically relieving stress on the coding installation or device.

[0049] In other words, the coding device ensures that a connection module is correctly engaged (particularly in the axial direction) in the connection slot only if the connection module has been properly engaged according to the connection slot in that connection slot. Otherwise, the connection of the connection module in the connection slot This cannot be done until the end (for example, according to the connection direction, i.e., the axial direction). The alignment device ensures that, particularly at the end of the connection phase, the connection module is correctly positioned in the connection location, in the plane (e.g., xy for a connection direction along the z-direction) perpendicular to the connection direction, and also to remain fixedly positioned in the connection location despite mechanical influences (e.g., vibrations or alternating thermal stresses). Thus, simple means allow for safe and damage-free connection assembly with the complementary connector.

[0050] This results in the advantage of a functional separation obtained with simple means.

[0051] Alternatively or in addition, the alignment device may be provided to have a lower or higher height (in particular depending on the direction of connection) (for example less than 10% in height or depth or, for example, less than 1 mm in height or depth) than the coding device.

[0052] If the alignment device is taller than the coding device, then advantageously, when mounting the connection module, the alignment (particularly in the xy plane) is first correctly adjusted before verifying or confirming with the coding device that the correct connection module is installed in the correct connection location. This has the advantage of preventing seizing.

[0053] If the height is low, then during reassembly, it will be advantageously possible to quickly determine whether the connection module is installed in a suitable connection location before adjusting the exact alignment (in the xy plane). Connection errors can be detected quickly. This allows for a particularly delicate alignment device.

[0054] In both cases, it can be foreseen that, for example, only a first alignment direction has a different height than at least a first coding element (for example, ribs of different or identical lengths at the connection location—the corresponding recesses as second alignment elements or second coding elements can be provided on the connection module, for example, respectively, they can have the same height). Or, for example, only at least a second alignment element has a different height than a second coding element.

[0055] Alternatively or in addition, the alignment device is installed at a lower or higher height (in particular parallel to the direction of connection) (for example, at a height or depth of at least 10% or for example, a height or depth of at least 1 mm) than the coding device.

[0056] If the alignment device is at a greater height (above the bottom) than the coding device, it is advantageous that, during the assembly of the connection module, its alignment (particularly in the x, y plane) is first correctly adjusted before then verifying, using the coding device, that the correct connection module has been installed in the correct connection location. This has the advantage of preventing jamming.

[0057] If the height is less, then during assembly it is advantageously possible to quickly determine whether the connection module has been installed in the correct connection location before adjusting the exact alignment (in the xy plane). Connection faults can be detected quickly, which allows for the implementation of the alignment device, particularly in a delicate manner.

[0058] It can be foreseen, by way of example, in both cases that, for instance, only at least one first alignment element is at a different height than at least one first coding element (for example, ribs or similar means spaced differently from the bottom at the connection location—the corresponding recesses as second alignment elements or second coding elements of the connection module can begin and / or end, for example, at identical heights respectively. Or, alternatively, for instance, only at least one second alignment element will have a different height than at least one second coding element.

[0059] It is clear that in principle an alignment device and an coding device can also be at the same height or installed or mounted at the same height. Thus, the two functions are applied simultaneously during the connection phase.

[0060] In a particularly preferred manner, the first alignment element (or at least the first alignment elements) of each bucket-shaped connection location are respectively in the same position (or in respectively identical positions) at each connection location.

[0061] Thus, there is the advantage of particularly simple manufacturing of the connection modules and connector housings. Furthermore, quality control after the manufacture of the housing and connection modules is particularly simple. In addition, there is the advantage of providing at least one first alignment element that can be specifically designed to ensure high positioning accuracy. For example, by providing several first alignment elements, these can have a particularly large gap between them.

[0062] Alternatively or in addition, the first alignment element (or elements) of each cup-shaped connection location are geometrically identical. This results in the advantage of a particularly The simple design of the housing and connection modules makes it particularly easy to manage. Furthermore, this greatly simplifies post-manufacturing quality control.

[0063] Preferably, the first and second alignment elements are complementary to each other.

[0064] This allows for very simple mechanical coupling when there is correct positioning between the connection module and the connection location.

[0065] Alternatively, or in addition, the first alignment element is provided only on the bottom area of ​​the cup-shaped connection slot, oriented towards the complementary connector, so that each wall in the vicinity of the bottom area of ​​the connection slot will not have a first alignment element, or that each wall in the remaining wall area or in the wall area beyond the bottom area will not have a first alignment element. Thus, the remaining wall areas of the connection slots (particularly above the bottom area) will be practically free of alignment elements and without coding elements. Furthermore, advantageously, this simplifies the manufacture of the connector or the wall arrangement of the connection slots.

[0066] Thus, (with the exception of the bottom area) the connection slot will have smooth walls, which considerably simplifies, in particular, the process of inserting a connection module into a cup-shaped connection slot. Furthermore, it has the advantage of simplifying the manufacturing of the connector or the design of the connection slot walls.

[0067] Furthermore, advantageously, no other functional element will be provided on the connection module (for example, a secondary, movable locking element) without the latter being influenced in operation, for example, by an alignment element which completely occupies the wall or without requiring a complicated geometric design.

[0068] The background area may occupy, for example, a maximum height of 25%, preferably a maximum of 15%, and particularly preferably a maximum of 10% of the respective wall height. The wall height is measured, for example, parallel to the connection direction of the connection module at the respective connection location.

[0069] According to another preferred development of the invention, the connection module has at least one (secondary) locking device which, in the engaged state of the connection module, applies against the connection location and which is designed to lock or hold at least one connection element in the connection module.

[0070] The secondary locking device advantageously has an optional primary latch for the connecting element in the connection module. Furthermore, advantageously, the provided secondary locking automatically ensures the Secondary locking of the connection element to the engaged state of the connection module relative to the connection slot. For example, the secondary locking device is designed so that the connection module can only be inserted into the connection slot or mounted in the connection slot if the secondary locking device has been properly engaged or closed. This eliminates the need for a separate secondary locking element (e.g., a slider) on the entire connector.

[0071] In the case of the secondary locking device, in the absence of primary latching or primary locking of the connecting elements in the connection module or the chambers of the connecting element, it is simply a locking device. Such primary locking or primary latching is, for example, implemented in the form of a latching spear on the connecting element or on the connection module in the respective chamber corresponding to the connecting element. It engages, for example, in an undercut (of the chamber) in the chamber or in the connecting element. This element is elastically reversible transversely to the direction of engagement of the connecting element in the chamber.

[0072] The (secondary) locking device can be designed to receive greater pull-out forces than those of a conventional primary hooking device.

[0073] The secondary latching device preferably includes a first tab. This first tab pivots about an axis for locking. Advantageously, at least one or more connecting elements can thus be locked into the connection module, in particular, even before the connection module is mounted in the associated connection location. This has the advantage that, even after the connection module has been fitted (and thus at a still very low level of value creation), it is possible to verify that the connecting elements are correctly installed in the connection module and, if necessary, correct the fitting.

[0074] A second tab for the secondary locking device can be provided, for example, on the side of the connection module opposite the first tab. The second tab can, for example, pivot around a (different or second) axis (in particular parallel to the axis of the first tab) during the locking phase. Thus, the same advantages are obtained as with the first tab. Furthermore, it is advantageous that, for double-row connection modules (i.e., connection modules that have two rows, in particular parallel rows, of connection elements in corresponding chambers), the individual connection elements can be locked securely in the connection modules or in their chambers using simple means.

[0075] In other words:

[0076] If one or both tabs fail to close, this indicates that at least one connection element is not correctly installed in the connection module. The two tabs offer the advantage of having, for example, the double-row trim of the connection module locked with the connection elements.

[0077] Alternatively, a single secondary locking device comprises the first and second tabs.

[0078] Preferably, for the (secondary) locking of the connection elements, a separate component of the connection module is not required.

[0079] In a particularly preferential way, the locking element (here in the form of the first tab or the second tab) is made in a non-losable way with the connection module.

[0080] The first tab and / or the second tab can be made in one piece with the connection module. The first tab and / or the second tab can be installed, for example, with a film hinge on the connection module.

[0081] For example, the first and / or second tab may be provided with a hook or a latching element or a hook-shaped element, for example, at their free end. Such a hook or hooking element or hook-shaped element may, for example, engage with an undercut of the connecting module and thus hook or clip the first and / or second tab onto the connecting module in the closed position. The hook or hooking element may, by way of example only, have a raised feature or a curve or similar characteristics. In other words: in the closed position, the respective tab is then protected against accidental or elastically reversible opening. Opening the respective tab (i.e., tilting outwards) may be achieved, for example, by unlocking the hooking element or the hook.Furthermore, and only as an example, it can be foreseen that the hook or hook element will engage in an undercut of at least one connection element installed in the connection module and thus be locked.

[0082] According to another feature, at least one first alignment element and at least one first coding element are juxtaposed on a line in the bucket-shaped connection location. The line is, for example, parallel to a wall of the wall assembly. Thus, the alignment elements and the coding elements are all on a common side of a wall of a connection location. The advantage is that the mechanical elements are arranged in such a way particularly compact for the correct association of connection modules and the correct positioning of the connection module at the connection location.

[0083] If there are several first alignment elements and several first coding elements and if these elements are on several walls of the wall arrangement, for example, on walls opposite each other of the wall arrangement, then, preferably, all the first alignment elements and the first coding elements installed against or on a wall are aligned next to each other.

[0084] According to one development, at least one connection module is hooked into the connection location, which advantageously allows for a very simple mounting of the connection module in the connection location.

[0085] Preferably, the connection module in the installed state at the connection location is coupled, that is to say, attached to the connection location in a way that cannot be lost.

[0086] For the attachment, for example, an attachment structure is provided at the connection point and a complementary attachment structure on the connection module. A single attachment structure and / or a single complementary attachment structure may be provided. Alternatively, there may be a set of attachment structures (for example, two, three, four, five, six or more) and / or a set of complementary attachment structures (for example, two, three, four, five, six or more).

[0087] For example, all the attachment structures for a connection point can be located on one side of the wall assembly or on a single wall of the wall assembly for the connection point in question. This offers the advantage of a particularly simple manufacturing process for the connection point. Furthermore, it results in a particularly compact footprint for the connection point.

[0088] According to another feature, the connection module has, on opposite sides of the connection module, one or more additional mounting structures. In this way, the connection module can be advantageously and securely mounted at the connection point, regardless of which side of the connection point wall or the mounting structures are located on.

[0089] The attachment can be made, for example, removable, thanks to a reversible elastic attachment structure. Thus, after assembly, in the event of a defect in a connecting element or a connection module, the connection module can be removed again without damaging the connection point, for example, by using a suitable tool. This offers the advantage of being able to easily repair the connector.

[0090] Preferably, at least one attachment structure and at least one additional attachment structure (in particular laterally) are beyond the first and second coding elements or are installed or constructed beyond the first or second coding elements. In other words:

[0091] There is no first or second coding element between the hooking structure or the supplementary hooking structure and the nearest adjacent wall to the connection location or the connection module. This provides the advantage of functional separation, particularly in the lateral direction, between the hooking and the coding. Alternatively, at least one hooking structure and at least one supplementary hooking structure may be provided or constructed (particularly laterally) beyond the first or second alignment element.

[0092] If, for example, there are two attachment structures on a wall at a connection point, it is possible, for example, to ensure that all the first coding elements and / or first alignment elements are located between the two attachment structures. This can be provided, for example, for each connection point of the connector.

[0093] According to another development, the wall device has a wall hooking element in the bottom area for hooking with an undercut of the connection module.

[0094] This has the advantage that the wall attachment element and the undercut of the connection module do not influence functional elements located higher up, for example, a (secondary) locking device. This achieves a spatial functional separation.

[0095] The wall attachment element (e.g., elastically reversible, for example, in the form of a hook or a lance) can serve as an attachment structure. The undercut of the connecting module can serve as a supplementary attachment structure.

[0096] It is clear that one can precisely foresee a wall attachment element which can also correspond to several wall attachment elements.

[0097] According to a preferred embodiment, all wall attachment elements are on the same side of a wall of the wall device of the respective connection location.

[0098] It is clear that, precisely, one can foresee exactly one undercut of connection module but that one can also foresee a set of undercuts of connection module.

[0099] According to a preferred embodiment, on the opposite walls of the connection module, connection module undercuts are respectively provided, in particular each time the same number of undercuts of connection modules (for example, each time a single undercut of connection module or several) in a particularly preferential way, the undercuts of connection modules are installed symmetrically in plan on opposite walls of the connection module, with respect to the median plane of the connection module.

[0100] Alternatively or in addition, the wall arrangement in the bottom area includes a wall undercut which can hook with a connecting module hooking element (e.g. elastically reversible, e.g., as a hook or as a hooking lance.

[0101] This has the advantage that the undercut of the wall and the connection module attachment element do not influence functional elements installed higher up, for example, a (secondary) locking device. This achieves a spatial functional separation.

[0102] The undercut of the wall can serve as a hanging structure. The connecting module hanging element can also serve as a supplementary hanging structure.

[0103] A single undercut of the wall can be provided, but several undercuts of the wall can also be provided.

[0104] According to a preferred embodiment, all the wall undercuts are on the same side of a wall of the wall arrangement of the respective connection location.

[0105] It is clear that one can foresee exactly one connection module attachment element, but also a set of connection module attachment elements.

[0106] According to a preferred embodiment, the opposite walls of the connection module each have connection module attachment elements, in particular each time the same number of connection module attachment elements (for example, each time a single connection module attachment element or several such elements). In a particularly preferred embodiment, the connection module attachment elements are on the opposite walls of the connection module, symmetrically arranged in a plane with respect to the median plane of the connection module.

[0107] The invention further relates to a connection device comprising a connector according to the invention and a complementary connector with at least one additional connection element. The additional connection element is designed for coupling with at least one connection element of a connection module in a connector.

[0108] The connection device can be designed, for example, for connection or plugging operations of electrical and / or optical sensor elements.

[0109] A (secondary) locking device is preferably designed to primarily hook connecting elements into the respective connection module, thus permanently fixing them. Preferably, a hook-shaped element engages behind the (secondary) locking device in an undercut of a connecting element.

[0110] It can also be provided that before engaging the connection module in the connection slot in the housing, at least one tab is closed, for example, manually or by machine. For example, this tab will be folded down or tilted towards the main area of ​​the connection module. Thus, several, or even all, of the engaged connection elements can be locked automatically by locking them in a secondary manner.

[0111] Mounting the respective connection module in the associated connection location will, for example, only be possible if the (secondary) locking device has been mounted or closed correctly.

[0112] Preferably, the (secondary) locking device is outside the bottom area of ​​the connection module (for example, in the middle area and / or in the head area).

[0113] Sliding or mounting the connection module in the connection slot is straightforward because, preferably, the coding and alignment elements are located in the back area of ​​the connection slot, facing the complementary connector. Therefore, a secondary locking mechanism (e.g., recesses for the coding ribs) is not required. When the connection module is removed from the connection slot, the secondary locking mechanism is easily and simultaneously released for several contact elements by folding back a tab.

[0114] According to another preferred feature, the second coding unit or the second coding element and / or the second alignment unit or the second alignment element of the connection module corresponds, in the area of ​​the connection module facing the background area of ​​the connection location (for example, below a maximum of 35% or, below a maximum of 25%, preferably below a maximum of 15% or, in a particularly preferred manner, below a maximum of 10% of the height of the connection module). Thus, the function of a tab of the connection module is not impaired. Other functionalities can also be easily provided. on the connection module, for example, beyond the background area without thus hindering, disturbing or influencing the second coding element and / or the second alignment element.

[0125] DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0126] With reference to figures 1 to 9, a connection device 1 consisting of a modular connector 2 and a complementary connector 3 is described in detail below.

[0127] Figure 1 shows the basic construction of a connection device 1 in exploded view. The connection device 1 comprises two main components, namely the connector 2 and the complementary connector 3.

[0128] The supplementary connector 3 here presents a supplementary connector housing 31 by way of example, in which there are, by way of example, several supplementary connection elements 30.

[0129] Connector 2 is assembled with complementary connector 3.

[0130] The connection device 1 optionally includes a cover 10 (for a cable exit) for the connector 2 and, optionally, a lever 11, that is, generally, an actuating element (it may also be a push button) which, here by way of example, acts upon the actual insertion between the connector 2 and the complementary connector 3, for example, thus releasing the connection. The lever 11 or the actuating element is Designed to reduce the maneuvering force for insertion or extraction. Insertion is done in the insertion direction, which here is parallel to the Z-axis.

[0131] The optional cover 10 of connector 2 can be rotated according to the desired cable exit, without difficulty by 180° or be provided or installed further below the housing 20 described for connector 2 or be engaged on it. In this case, the cable exit would be oriented to the right unlike in [Fig. 1].

[0132] The optional lever 11 can also be rotated 180° and / or according to the orientation of the optional cover 10 or be pivoted around the vertical axis on the connector 2 or on the housing 20 described below of the connector 2 or on the cover 10.

[0133] The connector 2 comprises a housing 20 (connector housing) which is shown in detail in Figures 2, 6, 8, and 9. The housing 20 is shown here, by way of example, in the shape of a rectangular parallelepiped. The edges are, for example, parallel to the x-axis (long side) and the y-axis (short side) in a Cartesian coordinate system whose third axis is the z-axis. The housing has a set of connection slots 21; here, by way of example, there are nine connection slots 21. The connection slots 21 are arranged here, by way of example, in three rows of three. Thus, a 3x3 matrix arrangement is shown; but other arrangements are obviously possible (for example, a 2x3 matrix arrangement or other matrix arrangement).The connection locations 21 are delimited respectively by a wall or a wall device 22 which surrounds them, or they are defined by the wall device 22, or the wall device 22 surrounds the respective connection location 21.

[0134] Each connection slot 21 is designed to receive a connection module 7. However, it is also possible that not all connection slots 21 are filled with connection modules 7. The figure shows, as an example, a connection module 7 inserted into a connection slot 21. Examples of connection modules of different shapes are shown in Figures 3 to 5. The connection module 7 may, for example, have a connection module housing 9. The connection module 7 may, for example, have at least one chamber 70 for receiving a connection element 12, or the connection module housing 9 may have at least one such chamber 70. In this embodiment, each connection module 7 has several chambers 70.

[0135] In this embodiment, particularly advantageously, all the connection locations 21 are identical in cross-section, i.e., in external dimensions. All the connection modules 7 have, for example, the same cross-section or the same external dimensions. This simplifies the planning of the use of the various connection modules and also facilitates installation, particularly in an automated manner. This results in a concept of This modular connector is particularly simple and economical. If the user does not want to use the entire surface area of ​​a connection module 7, or is unable to do so, then several chambers 70 of the connection module 7 remain empty, or a connection module 7 with fewer chambers 70 is provided. Thus, the user can variably design the internal layout of a connection module 7. However, the external shape of each connection module 7 ensures that it can only be correctly installed in a single connection slot 21. This allows for simple and easy-to-automate mounting of connection modules 7 in the connection slots 21; at the same time, the user has a high degree of flexibility in the use of the connection surface. This enables the implementation and use of complex connection configurations in a simple and economical manner.

[0136] Advantageously, the connection modules 7 are provided to have a different color or colors (in Figures 3, 4, 5, and 9 this is represented by different hatching) depending on the connection location 21 to which they are associated, or depending on the coding 4, or depending on the type of the second coding element 42. This facilitates the allocation of the connection locations 21 with the corresponding connection modules 7. Particularly advantageously, a different color is provided for the appropriate connection module 7 for each connection location 21. Such color coding allows for automated assembly of the housing 21 with the connection modules 7 in a particularly simple and reliable manner. Color recognition for automated assembly can be achieved, for example, with a camera and operating electronics.For example, the connection modules 7 can be illuminated with a defined wavelength, and the infrared spectrum (or any other spectrum) of the illuminated connection module 7 can be captured and analyzed. Based on this analysis, the module can be associated with the appropriate connection location 21. This is then verified using the mechanical coding device 4. For instance, the color of the connection module 7 can be applied during manufacturing in the injection molding process using colors different from those of the material being used, for example, plastic. This results in simple and economical manufacturing of the plug-in modules 7. Furthermore, the color, and thus also the nature or type of the connection module 7, will be clearly recognizable from all directions, enabling particularly simple and reliable automated assembly of the housing with the connection modules 7.

[0137] Fig. 3 shows, by way of example, a connection module 7 with two parallel rows of chamber 70, of rectangular and in particular practically quadratic section.

[0138] Fig. 4 shows, by way of example, a variant of connection module 7 with three large chambers 70 in rows and having rounded edges.

[0139] Fig. 5 shows, by way of example, two rows of each time five small chambers 70 of substantially quadratic section with rounded corners.

[0140] Thus, the connection modules 7 are designed to receive at least one connection element 12 and, preferably, several connection elements 12 in a captive manner. Preferably, one connection element 12 is provided for each chamber 70. In the case of the connection elements 12 shown (for example, in [Fig. 7]), these may be electrical contact elements or optical connection elements (e.g., light guides, diodes, or the like), or even sensor elements. This connection element 12 has a latching blade 13 or a primary latching element for primary locking or primary latching. The latching blade 13 may be elastically movable reversibly transversely to the engagement direction.It can be attached, for example, to an undercut 86 (primary attachment) of the connection module 7 or the connection module housing 9 when the connection element 12 is placed in the connection module 7. This prevents, at least temporarily, the extraction or falling of the connection element 2 during the connection module 12. The connection element 2 can be connected, for example, to a cable 14. For example, a conductor of the cable 14 can be crimped to the connection element 12 (see [Fig.7]).

[0141] As further shown in [Fig. 3]-5, the connection modules 7 are practically rectangular in shape with two long sides (here, for example, parallel to the x-axis) and two short sides (for example, parallel to the y-axis), and, for example, a locking device 8 (secondary locking) is provided on the long side. The (secondary) locking device 8 comprises, for example, a first tab 81 on a first long side and a second tab 82 on a second, opposite long side. The two tabs 81, 82 can pivot about an axis which is parallel to the x-axis or parallel to the long side. They are connected, for example, only to the connection module 7 or to the connection module housing 7 by a hinge film 85 (see [Fig. 7]). Their free end has a hook-shaped area or a hook element 83.The hook or hook element 83 at the free end is shown here, by way of example, facing inwards, i.e. towards a connection module housing 9; the chambers 70 are made in the connection module housing 9. The hook or hook element area 83 is designed to lock the connection elements 12 which are engaged in the chambers 70 of the connection module 9 and, where appropriate, hooked in a primary manner (see [Fig. 7]) to lock them (secondary locking). In addition, the hook element 83 has a relief 84 or reinforcement (see also the . [Fig.7], which is oriented upwards). This relief 84 allows the tab 80, 82 corresponding to an undercut 87 (locking) of the connection module housing 9 to be hooked, which is notably detachable without destruction so that the tab 81, 82 cannot be detached accidentally if it is put in the closed (locked) position (see [Fig.7]).

[0142] Before fitting the housing 20 or the corresponding connection slots 21, the (secondary) locking device 8 must be closed, i.e., locked. For this purpose, the first and second tabs 81, 82 are pushed towards the housing 9 of the connection module 7, as an example. The locking mechanism is then engaged using the hook area or the hook element 83. The hook element 83 engages behind an undercut 15 of the connection element. The connection element 12 or the connection elements 12 are thus protected against being pulled out of the connection module 7 or are blocked. The primary hooking lance or the optional hooking lance 13 or primary hooking element is thus unloaded (see [Fig. 7]).

[0143] It is evident that the connection modules 7 in other embodiments can also be made without the secondary locking device 8.

[0144] Furthermore, the embodiments indicate in which the connecting elements 12 are not hooked to the primary hook or primarily locked in the connecting module 7. In this case, the secondary locking device 8 will be, for example, the only locking or the only element that protects or blocks the connecting elements 12 at least along the direction of engagement in the respective chamber 70 (here also parallel to the z-axis) against extraction. Nevertheless, for the sake of readability, the term secondary locking device 8 is used for such cases, although in the following cases, it generally refers to a locking device.

[0145] To automate or facilitate the automation of the engagement of the plug-in module 7 in the housing 20, the connector 2 has a mechanical coding device 4 located between each plug-in position 21 and each engaged plug-in module 7. The mechanical coding device 4 thus has coding elements both at the connection position 21 and also on the connection module 7. This defines the association between the connection module 7 and the connection position 21. Only one connection module 7 can therefore be correctly installed in a specific connection position 21. For each connection position 21, only a single type of connection module can be engaged (adapter solutions of connection modules 7 that are suitable for several connection positions 21 are made suitable by appropriate coding devices, for example, recesses at all the respective positions of the connection module 7, or it is possible in principle to implement, for example, early coding elements 41 in the form of relief or rib or even inverse variants which are not represented here).

[0146] More specifically, the mechanical coding device 4 has a first coding element 41 (see [Fig. 6]) and a second coding element 42 (see Figures 3 to 5) complementary to the first coding element 41. The first coding element 41 is provided at the connection location 61 (shaped like a cup), or the complementary second coding element 41 is provided on the connection module 7. For example, the first coding elements 41 of the connection locations 61 can be formed or added to the respective wall. In particular, it forms a single piece with the respective wall. As shown in Figures 3, 4, and 5, the second coding element 42 is formed in the form of slotted recesses on the long sides of the connection module 7. It occupies only the lower area (approximately the lower 10%-20%) of the connection module housing 9, which is also referred to as the bottom area 23.The first coding element 41 is made at the connection location 21 in the housing 20 as a raised area, complementary to the recesses. In principle, another embodiment is also possible, for example, the connection module 7 can receive, alternatively or in addition, studs or angled pieces that protrude downwards or laterally and engage in corresponding recesses in the connection location 21.

[0147] As the first coding element 41, a single element is provided (for example, a stud, a raised or projecting area, a ramp, a recess, a hole, etc.) or several elements (for example, studs or raised areas or biases or recesses, holes, etc.).

[0148] Similarly, and as a second coding element 42, a single element or several elements may be provided; this element or these elements are mechanically adapted to each respective first coding element 41 (key and lock principle). They may thus be complementary elements.

[0149] Each first and second coding element 41, 42 of each coding device 40 is of a different embodiment and / or each first coding element 41 is in a different position in or on the connection location 21 and each corresponding, adapted second coding element 42 is in a different corresponding position in or on the connection module 7. In other words: each connection location 21 can only receive one type or nature of connection module 7, only one type or nature of connection module 7 can be engaged or installed correctly.

[0150] As shown in [Fig. 6], the first mechanical coding elements 41 are in the form of raised areas at the connection location 21 for only one background area 23 oriented towards the complementary connector (this background area 23 extends here, for example, up to a maximum of 10% or a maximum of 15% or a maximum of 20% in height (parallel to the z direction) of the wall of the connection location 21) of the connection location 21. This also appears clearly in figures 3 to 5 in which the second coding elements 42 are only realized in the lowest area of ​​the connection module housing 9 (i.e. at the lowest height of the bottom area 23 which corresponds to 10%-20% of the height of the connection module housing 9).

[0151] As shown in [Fig. 2], the walls or partitions of the wall assembly 22 in the remaining wall area (upper area), which also extends from the bottom area 23 towards the engagement opening, do not have any coding elements or other features. In this area, the walls are smooth, in particular without any raised features. In this embodiment, the wall has, in the area above the bottom area, a particularly simple, non-sticking, and friction-free engagement of the connection module 7 in the connection slots 21. Furthermore, in this way, additional features can be provided on the outer side of the connection module 7, for example, tabs 81, 82 of the (secondary) locking device 8, without these being obstructed, for example, by coding ribs along (virtually the entire) height of the wall or in the upper area of ​​the respective wall.In other words: we can have a functional separation by distributing the functions (for example, coding, alignment, locking, etc.) at different heights of the connection locations 21 or the connection modules 7.

[0152] In each instance (here, by way of example), two corners of the connection slots 21 have a rib extending from the bottom area 23 to the top, or a rotation rib 25. This rib serves as an anti-rotation device that prevents the connection modules 7 from being engaged and rotated 180° around the vertical axis in the connection slot 21. Corresponding recesses are also provided on the connection modules 7 (on all connection modules 7 in the same location). However, these anti-rotation elements do not prevent the functional separation described above because they are only provided in the corners, and the wall is continuously smooth in its upper area; in particular, it does not have any raised elements.

[0153] As shown in [Fig. 6], the bottom area 23 has a peripheral edge 24 on which the first coding elements 41 rest or which comprise the first coding elements 41. The first coding elements 41 are, for example, also connected here to the wall of the wall assembly 22. The height in the engagement direction of the first coding elements 41 is, therefore, reduced, as shown in Figures 3-5 for the second, complementary coding elements 42. of the connection module 21 so that the remaining wall areas of the connection location 21 are smooth.

[0154] Furthermore, the connector 2 has an alignment device 6 comprising a first alignment element 61 and a second alignment element 62. The alignment device 6 thus ensures the correct orientation of the connection module 7, engaged in the connection slot 21 (xy plane). As with the coding elements 41, 42 of the mechanical coding device 4, the alignment elements 61, 62 of the alignment device 6 are, for example, complementary to slots or raised areas. Thus, the second alignment elements 62 are made, for example, in the form of slots or recesses (at least one slot or recess) and the first alignment elements 61 are raised areas or studs or ramps (at least one raised area or stud or ramp).It is clear that one can also have a reverse realization and a mixed realization (at least one slot or recess as the first alignment element and at least one raised area or stud or ramp as the second alignment element).

[0155] According to [Fig.6], the first coding elements 41 and the first alignment elements 61 are provided respectively on the edge 24 of the background area 23. Thus, the first coding elements 41 and the first alignment elements 61 are on a common line perpendicular to the connection direction (parallel to the z-axis) of the connection modules 7. The background area 23 thus has, on each long side of each connection location, a first coding element 41 and a first alignment element 61.

[0156] The first alignment elements 61 of the alignment device 6 can be provided to be of greater height or a greater distance from the edge than the first coding elements 41 of the coding device 4. For example, the first alignment device can have a height at least 10% greater than that of the coding device. This has the advantage that, during assembly, the correct positioning of the connection module 7 in the connection slot 21 is first achieved, and at the end of the engagement phase, it is ensured or confirmed that the correct connection module 7 has been engaged in the connection slot 21.

[0157] The connection device 1 further includes an engagement aid 5 which facilitates the engagement of connector 2 into the complementary connector 3 or vice versa. The engagement aid 5 includes a recess 52 for receiving a blade 51 of the complementary connector 3 (see Figures 1 and 8). As shown in Figure 6, the recesses 52 are provided between the connection locations 21. In addition to the recesses 52, there are blades 51 on the complementary connector (see [Fig. 1]). The engagement aid 5 thus facilitates the insertion of connector 2 into the complementary connector 3 and guides the connector 2 within the recesses 52 during the engagement process. The recesses 52 are closed here, as an example, by an intermediate base 53 (see [Fig. 9]). They have one end open downwards (towards the auxiliary connector 3 or the blade 51, see Figures 8, 9). This creates a pocket-like shape. The upper end is open and pocket-like. The intermediate base 53 prevents the ingress of fluid or dirt into the recesses 52 towards the auxiliary connector 3. It also increases, for example, the stability of the recess 52 and / or allows for thinner walls that define the recess 52. The blade 51 can simultaneously provide a protective function against contact with the auxiliary connector 3 and / or a protective function against damage to the auxiliary connection elements 30 of the auxiliary connector 3.

[0158] The recesses 52 have a smaller cross-section than the cross-section of the connection locations 21. By the arrangement between the rows of connection locations 21, a very compact connector device 1 is obtained.

[0159] The alignment device 6 is made between each connection location 21 and each connection module 7. The alignment device 6 thus fixes the final insertion position of the connection module 7 in the connection slot 21 (particularly in the cup shape) by ensuring (in the xy plane). The alignment device 6 may have a tolerance between the first and second alignment elements 61, 62 that is less than the tolerance between the first and second coding elements 41, 42 of the mechanical coding device 4.

[0160] The first alignment elements 61 and the first coding elements 41 are realized here by way of example, in the form of studs or ribs or reliefs of the wall on the inside side of the connection location.

[0161] In this embodiment, the alignment device 6 is higher than the coding device 4. Thus, for example, the first alignment element 61 or the first alignment elements 61 are higher than the first coding element 41 or the first coding elements 41 (in [Fig. 6], the first alignment elements 61 are closer to the observer than the first coding elements 41), parallel to the direct engagement. During the engagement of the connection module 7 in the connection slot 21, at least one first alignment element 61 encounters at least one second alignment element 62. The correct lateral alignment (xy plane) of the connection module 7 in the connection slot is achieved. During the subsequent engagement, the coding device 4 comes into play.When the connection module 7, adapted to the connection location 21, has been engaged, the first and second coding elements 41, 42 are adapted to each other; that is, the two coding elements 41, 42 are matched. The connection module 7 can be fully engaged in the engagement direction z. the connection location 21 (see [Fig.9] and at the end of the engagement operation there is a hook). In figures 3-5, it appears that the second orientation elements 61 and the second coding elements 41 (realized here in the form of recesses) have the same height, which is not contrary to the functional sequence described above (first alignment in the lateral direction then control of the engagement by error).

[0162] Alternatively, or in addition, the coding device can also be had at one height or another height, in particular at the engagement location 21 as an alignment device 6.

[0163] The first and second alignment elements 61, 62 as well as the first and second mechanical coding elements 41, 42 are provided in the bottom area 23 of the connection locations 21 and do not disrupt the engagement which will take place on a large part of the connection locations 21 on smooth walls.

[0164] The alignment elements 61 and the coding elements 41, 42 do not interfere with the secondary locking device 8, preferably against the engagement of the connection modules 7 in the connection locations 21 by the folding down of the tabs 81, 82 which activate it.

[0165] Figure 7 shows, by way of example, a section of a connection module 7. Figure 7 shows two connection elements 12, here implemented as electrical contact elements. These connection elements 12 can thus be easily engaged in the chambers 70 and hooked by the primary hooking, for example, with the primary locking device or primary hooking device. For this purpose, a safety feature to prevent loss of the connection elements 12 is provided in the chambers 70 of the connection module 7. At the lower end of [Fig.7] (facing the opposite connector) for both cut chambers 70 there is each time an engagement hole 88 in the housing of the connection module 9. This engagement hole 88 allows, for example, an additional connection element 30 to be engaged in the chamber 70 and coupled to the connection element 12, for example, to make an electrical and / or mechanical and / or optical connection.

[0166] This can be done, for example, with at least one latching lance 13, in particular elastic, reversibly movable, or primary latching lance or lances in or on the connecting element 12 itself (in principle, such a latching lance can also be considered on or in the connection module housing 9 or in the chamber 70, which then latches onto an undercut of the connecting element 12). On the left side of [Fig. 7], the first tab 81 is shown in the open position (first position) PI. The hook element 83 has not yet reached a locking position.

[0167] On the right side of [Fig.7], the second tab 82 has been tilted around the tilting axis (here by way of example, made by or near a hinge film 85 in a second closed position P2 in which the hook element 83 comes into an undercut of the connecting element 15 of the right connecting element 12 and thus avoids the extraction of the connecting element 12 in the opposite direction to the engagement direction (here upwards) in the connecting module 7. In the state of the connecting module 7 engaged in the connecting location 21, the two tabs 81, 82 are in the closed (second position).

[0168] In the (second) closed position P2, the first or second tab 81, 82 are coupled, for example, as shown here, hooked by their free end to the connection module housing 9 so as not to move on their own to the open (first) position P1. This is achieved, here by way of example, by a raised feature 84 (here projecting upwards) of the hook element 83 which hooks behind a (locking) undercut 87. On the side opposite the raised feature (facing the complementary connector 3) the hook element 83 engages with the undercut of the connection element 15. The hook element 83 is thus in a closed (second) position relative to the connection element 12 between the undercut of the connection element 15 and the cable 14 or the crimped segment 16 of the cable 14.

[0169] A connection module 21 may be provided which has a (secondary) locking device 8 that can only be installed, engaged, or mounted at the connection location 21 (for example, without damage and / or by applying reduced force) if the (secondary) locking device 8 is in the closed (second position) P2 position or is closed. If, for example, a connection element 12 is not correctly installed in the connection module 7, the corresponding tab 81, 82 cannot be moved to the closed (second position) P2 position, and therefore the connection module 7 cannot be installed at the connection location 21. In this way, a defect can be detected in a particularly simple manner, even in the case of automated manufacturing or assembly of the housing 20 with connection modules 7.

[0170] It should also be noted that another connection module 12 can be installed in each connection module 7 so that the connection modules 7 can perform a wide variety of functions. The connection elements 12 are, for example, selected from the group of electrical contact elements or optical elements, for example, transmitting elements, receiving elements, optical coupling elements, sensor elements, or similar elements. A combination of electrical and optical elements or sensor elements (for example, magnetic sensors that cooperate with a magnetic field or with a magnet from the complementary connector 3 or inductive sensors, etc).

[0171] Furthermore, each connection module 7 can be made differently depending on the additional connector 3 or the application to receive different connection elements 12 and / or a different number of connection elements 12. In addition, [Fig.2] shows, as already indicated above, that in the corners of the wall device 22 of the connection locations 21 one or more anti-rotation ribs 25 can be provided. The anti-rotation ribs 25 prevent the connection module 7 from being engaged in a rotated manner, for example 180° relative to the housing 20 of the connector 2, during the engagement phase, for the connection module 7 to be engaged in the assigned connection location 21.

[0172] The tolerance of the alignment device 6 is, for example, less than 20% of the tolerance of the coding device 4. The tolerances preferably relate to the position at the connection location and / or dimensions such as the width and / or length and / or height of the elements.

[0173] In this embodiment, the coding elements 41, 42, the alignment elements 61, 62, and the engagement aid elements 5 are described as being primarily raised and recessed features, each associated with a component. However, raised and recessed features can also be provided on other parts of the component. For example, in the case of a mechanical coding device 4, several different coding elements 41 can be provided on the housing 20, for instance, in terms of raised areas and recesses. This also applies to the alignment elements 61, 62.

[0174] The extension of the coding elements 41, 42 and the alignment elements 61, 62 in the engagement direction (here this direction is parallel to the z direction or the z axis) corresponds, for example, to a maximum of 25%, preferably to a maximum of 20% and in a particularly preferential manner, to a maximum of 10%, in particular a maximum of 5% of the entire wall height (z direction) of the connection location 21.

[0175] The [Fig.8] is a diagram of the housing 20 of connector 2 in the direction of the complementary connector 3 (viewed from below).

[0176] By way of example, for each connection location 21, two latching structures 92 are identified for coupling to complementary latching structures 93 (see [Fig. 9]) of the connection module 7. The connection module 7 is fixed to the connection location 21 (see also [Fig. 9]). This may, in particular, be a lockable latching mechanism so that the different connection modules 7 can be exchanged simply and quickly. The two structures 92 attachment points are provided here, for example, each time at the outer ends of one of the two long sides or of the long side walls. Between them, one can have the alignment device 6 with at least one first alignment element 61 and the coding device 4 with at least one coding element 41 (or at least parts of such elements can be provided between the attachment structures 6).

[0177] As a hooking structure 92, for example, there are two wall hooking elements 90 made in the bottom area 23 of the wall device 22. The two wall hooking elements 90 of the respective connection location 21 can hook onto two corresponding undercuts of the connection module 91 of the connection module 7 and which represent the complementary hooking structure 93 (see [Fig.9]).

[0178] Alternatively or in addition, the wall device 22 may have, in the bottom area 23, at least one wall undercut which can hook onto at least one hooking element of the connection module 7.

[0179] Figure 9 is a schematic section of connector 2 of Figure 1. Three connection locations 21 are shown in section; in the two outermost connection locations 21, a connection module 7 is engaged each time. As can be seen (in combination with Figures 3 to 5), the additional attachment structures 93, in this case the undercuts of the connection module 91, are provided on the two long sides of the connection module 12, even though the attachment structures 92, in this case the wall attachment elements 90, are only on one side of the connection location 21. In this way, the connection locations 21, although they ensure the attachment of the connection modules 7, can be made with a particularly small (particularly narrow) footprint.At the same time, the additional mounting structures 93 on the opposite sides (walls) of the connection module 7 ensure great flexibility for the arrangement of the mounting structures 93 at the connection location 21. Indeed, for example, for other housing shapes (such as for other matrix arrangements) it is possible, without difficulty, to provide the mounting structures 92 (exclusively) on the opposite sides without having to modify the connection module 7. In principle, it is naturally also possible to have the mounting structures 92 on both walls or sides (opposite each other).

[0180] Preferably, the additional attachment structures 93 are provided on the connection module 7, in a symmetrical planar manner with respect to the longitudinal plane (or a transverse plane) of the connection module 7.

[0181] In other embodiments, the hanging structure 92 or the supplementary hanging structure 93 may be provided on one or both of the short sides. It is also possible to have only a single structure hanging structure 92 or additional hanging structure 93 or more than two hanging structures 92 and additional hanging structure 93.

[0182] The invention as described makes it possible to produce connectors with different configurations corresponding to a modular, box-like system. In particular, the number of connection slots 21 can be easily increased or decreased with a different housing 20 (generally, by adapting to customer requirements). The connection modules 7 can thus be used independently of the housing size. This box-like system avoids the costly development of customer-specific connectors or connector devices and simply requires adapting the housing 20 with the corresponding mechanical codings to prevent any module engagement errors. If, for example, the number of connection slots 21 increases from 9 to 12 (from a 3x3 matrix to a 4x3 matrix), then the first nine codings can be left as is, for example, and only three new codings added.Thus, in this modular system, the first nine types of connection modules will be used for the two 1-pin connectors, and for the nine connectors, it is sufficient to add three additional types of connection modules.

[0183] The geometric shape of the mechanical coding devices can be chosen in any way, preferably in the form of small columns or small ribs and complementary recesses. The arrangement in the bottom area 23 of the connection locations 21, which is oriented towards the complementary connector 3, allows for simpler engagement than between otherwise smooth walls.
