    Descriptive Report of the Invention Patent for MODULAR SYSTEM FOR FITTING CONNECTOR MODULES, FITTING CONNECTOR UNIT, AND MODULAR HOUSING STRUCTURE FOR THE SAME.
    [001] The invention generally relates to a modular system for the production of plug connector units based on different plug connector modules, in particular rectangular plug connector units for different types of transmission and a connector unit corresponding plug-in. The invention relates specifically to a modular housing structure for this purpose.
    [002] In particular, the invention relates to the field of electrical connectors, that is, plug connectors for electrical energy and / or electrical signals.
    [003] A generic modular system with a plurality of different plug connector modules is, for example, offered by HARTING Deutschland GmbH & Co. KG, D-32427 Minden, under the trade name Han-Modular® System. This system is described for example in the catalog HARTING Selection Guide - HanModular® Steckverbinder (Version 3, 11/21/2016). Other manufacturers offer comparable systems. This allows you to connect different plug-in modules to a single unit.
    [004] This is done, for example, in the HARTING company system based on a so-called retaining frame, in particular hinged frame with several identical housing elements for the accommodation of several plug connector modules in the hinged structure. The articulated structure has two parallel longitudinal side walls, which define the structure width and perpendicularly to this, two parallel narrow side walls, which define the height of the structure. In this system, the rotating joints are provided for in the
    Petition 870190096173, of 26/09/2019, p. 24/64
    2/30 narrow side walls, which serve to open and close the longitudinal side walls to or from a locking position. The DE 197 07 120 C1 patent describes this articulated structure and its interaction with plug-in connector modules. The articulated structure allows the mechanical connection of the designed connector modules with the corresponding modular fixing means.
    [005] An example of a suitable plug-in connector module is shown in figure 3 of patent document DE 197 07 120 C1, others are described for example in patent document EP 1 398 853 B1.
    [006] With a system according to the generic concept, optionally, a plurality of different plug-in connector modules for different transmission media, such as electricity, signals, operational means, etc., can be combined in one connector unit of fitting. Merging different plug-in modules into one unit reduces installation and maintenance times and reduces space requirements. As can be seen in the aforementioned catalog and patent document EP 1 398 853 B1 (cf. Fig. 4), in the state of the art system, after assembly with the desired connector modules, an articulated structure is provided with a connector or complementary housing, which serves as the actual housing of the plug-in connector unit and for example has the cable eyelets or fixing means for installation.
    [007] In another generic system from another manufacturer and other plug connector modules is described by patent EP 1 309 040 B1 (Figure 5). In figure 6 of patent document EP 1 309 040 B1, a principle is also apparent in which several identical housing structures are arranged side by side in an extension direction as a unit, each of the housing structures accommodating only a single module plug connector.
    Petition 870190096173, of 26/09/2019, p. 25/64
    3/30 [008] Furthermore, as for example in US Patent 3,289,145 A or DE-OS DE 30 14 755 A1, non-generic systems are known in which the insulating bodies of the plug-and-socket connector are lined up one next to each other to make electrical contact and are connected to each other by means of connection, which are provided directly on the connectors or sockets, forming a unit. Here, no separate retaining structure and no plug or socket housing are provided. This alternative modular principle for the plug and socket connector body allows only low mechanical loads, only partially enables the combination of different transmission media and is unsuitable for many industrial applications. In addition, the sealing classes required in the industry are difficult to carry out. In addition, in US Patent Document 2011/0287661 A1, connectable housing structures Al have been proposed, which are intended for the assembly of special coaxial interconnection sockets in the frame of a rack. In addition, this approach is not in accordance with the general principle or is outside the field of application, since in the case of the frames they are merely assembly aids for the installation of a rack, but not of parts of the carcass. plug connector units themselves, that is, units that are pluggable as a connector and corresponding plug connector.
    [009] The modular system according to the aforementioned generic concept has demonstrated good results in practice, however, and offers many advantages. However, several different components are required, for example with different widths of articulated structure and a plurality of connector housings, sockets or complementary.
    [0010] A first task of the present invention lies in the fact that it increases the modularity of the system, in which preferably at the same
    Petition 870190096173, of 26/09/2019, p. 26/64
    4/30 m time a reduction in the total required number of components or modules of the modular system is possible. The plug connector unit built here must be particularly suitable for electrical connectors in industrial applications. This task is solved by a modular system according to claim 1 and regardless of that by a modular housing structure according to claim 15.
    [0011] The modular system according to the generic principle for connector modules, in particular for the production of rectangular connectors, comprises a series of housing structures, but in any case at least a first housing structure with several housing elements identical to house several plug connector modules within the housing structure, where the housing structure has two parallel longitudinal side walls, which define the width of the housing structure and perpendicularly there two parallel narrow side walls, which define the height of the carcass structure.
    [0012] According to the invention, it is provided in this first type of carcass structure, that the structure width is substantially an integer multiple of the structure height, that is, exactly an integer multiple plus a first gap (excluding the tolerance of manufacturing), this gap is designed as a predetermined joint gap size; longitudinal side walls and narrow side walls, that is to say, all side walls, each having connecting elements, in particular for detachable connection based on the external sides and preferably for connection in positive union or fixation, where respectively a connecting element of a longitudinal side wall with a connecting element corresponds to a narrow side wall corresponds or both have a suitable configuration for interaction for purposes of fixing to another structure
    Petition 870190096173, of 26/09/2019, p. 27/64
    5/30 carcass; and on each longitudinal side wall, at least two connecting elements are spaced apart from each other at a grid distance, where that grid distance measured along the width of the structure substantially corresponds to the height of the structure, that is, exactly the height of the frame structure plus a second pre-determined assembly clearance (manufacturing tolerance excluded).
    [0013] The combination of characteristics above makes it possible for a plurality of housing structures - possibly also identical by the first type - to be mechanically connected mechanically to each other based on their connection elements to form a connector unit.
    [0014] In this case, the first frame structure with almost N times the frame width in relation to the frame height selected as the basic unit, represents a basic module or a basic housing module, which extends the modularity of the connector system, for example so to speak, to the housing plan for an additional second level. On the one hand, the housing structures serve in this case, individually or with other housing structures, as an effective housing for the housing of plug connector modules known per se, which represent the so-called first module level. These connector modules essentially consist of a modular insulating body and electrical contacts or other media connectors, which hold the insulating body in a predefined position. In addition, through a small number of housing structures that interact in modular construction (such as modular components) the number of components required for the production of housings, in particular rectangular connector housings. It is no longer necessary, among other things, for a plurality of connector sizes to keep stock retention structures in stock.
    Petition 870190096173, of 26/09/2019, p. 28/64
    6/30 properly sized, plug connector housings, socket housings, complementary housings, etc.
    [0015] An important aspect here is the dimensioning of a grid-like correspondence in the two extension directions perpendicular to the installation depth of the carcass structure, that is, in width and height. In these two extension directions perpendicular to the connection or assembly plane (perpendicular to the installation depth), the dimension of the longitudinal side and the dimension of the narrow side are selected in a ratio of sides suitable for module N modularity. In other words, the dimension in the extension direction of the longitudinal side is always n-times the dimension in the extension direction of the narrow side, neglecting the slight assembly clearance, where N represents an integer, in particular from 1 to 4, preferably 2 to N, preferably with 2 <N <4.
    [0016] Another important aspect is the predefined dimension according to which the connectors are arranged in a modular way, so that several housing structures can be optionally assembled as components of a module. At least one connecting element or only one connecting element can be provided on the narrow side walls, at least two connecting elements are always provided at the distance of the predefined dimension, on the long side walls.
    [0017] When assembling several housing structures, a connector unit can be formed, which can be connected as a connector in one step, with another connector unit, in particular with a connector unit composed analogously of modular structures housing, as a corresponding connector, or can be removed from it. Both to dimension the side walls and to determine the predefined dimension of the elements
    Petition 870190096173, of 26/09/2019, p. 29/64
    7/30 of connection, an adequate mounting clearance must be planned respectively, which facilitates assembly in any direction and takes into account manufacturing tolerances and, possibly, also slight deformations of the housing structure. This facilitates the assembly of connector units from the individual housing structure. The first mounting clearance for n-times the dimensioning of the longitudinal sides can be identical to the second mounting clearance in the predefined dimension. Both are only a very small percentage, in particular «5%, preferably <3%, of the dimension in the direction of extension of the narrow side (perpendicular to the depth). The first and second mounting clearance may be, for example, from a few tenths of a millimeter to a few millimeters, depending on the dimension of the narrow side in the direction of extension of the mounting plane. The mounting clearance is adjusted sufficiently to be small, respectively, to ensure a tight fit or union of the interconnected housing structures. The fixing of the carcass structure must be carried out essentially without relative clearance.
    [0018] The modular housing structures within the meaning of the invention thus unite, at least in large part, the function of the articulated structure previously known to the function of the housings of plug connectors, sockets or complementary ones that house this, in a module modular.
    [0019] The or each carcass structure can be assembled or built in one piece or preferably be composed of several parts. The carcass structure can be composed of two main parts. In one embodiment, the housing structure has three main parts, in particular a front part in the form of a structure, which itself or through a retaining structure, forms the receptacles for individual connector modules and two back parts in the form of shell cooperatives who, in particular in the direction
    Petition 870190096173, of 26/09/2019, p. 30/64
    8/30 of the depth, are connected to the front and to each other perpendicularly to it. In this way, it is possible to facilitate the cable assembly and, possibly, obtain a fixing effect with regard to elastic strain relief. For this purpose, in particular, an elastic strain relief device can be provided in the internal space between the cable passage openings and the receptacles of the connector modules. Alternatively, a strain relief can be performed with only one main part at the rear.
    [0020] Another noteworthy aspect is the configuration with connectors on the four external sides of the housing structure, that is, on each side wall. As a result, modular assembly is possible in both extension directions, perpendicular to the depth of the structure or to the direction of the connector (in the assembly plan). This allows for a relatively freely selectable total dimension in both dimensions of the modular connector unit.
    [0021] In particular, in the case of the first basic module or the housing structure of the first type, the structure width can be exactly twice (twice the dimension) of the structure height plus mounting clearance.
    [0022] Furthermore, at least one carcass structure of a second type, which represents the smallest unit or the smallest component of the structure module, can be provided as a second component. This housing structure has at least two identical receptacles for mounting various connector modules within the housing structure, for example, by fixing in positive union.
    [0023] Again, according to the invention, similar to the first type, in the second type of carcass structure, it is predicted that the width of the structure is equal to the height of the structure, that is, the multiple N with N = 1; all the side walls have at least one possibly several connecting elements, respectively
    Petition 870190096173, of 26/09/2019, p. 31/64
    9/30 particular for positive coupling connection, in which a connecting element of a side wall to a connecting element of the adjacent side wall and, in particular, also corresponds, respectively, to a connecting element of the longitudinal side wall or narrow side wall of the first carcass structure.
    [0024] Thus, several second housing structures can be connected modularly by means of their connecting elements, to at least one additional housing structure, in particular of the first type, to form a connector unit.
    [0025] The correspondence of the connection elements must be understood in this case in general terms. The mutually corresponding connection elements can interact directly with each other or be designed for fixation by a separate additional connection element, which is designed to fit the two corresponding connection elements. A particularly simple embodiment of the modularly extended modular system for connector units consists of only the first type of housing structure mentioned above or only the two types of housing structure mentioned above and, where appropriate, additional compatible components that do not house modules of connectors, in particular matching covers or rear side latches and, for example, mounting plates, mounting elements, connector latches, etc. At least one modularly usable connection element can also be part of the modular system.
    [0026] With only one type of housing structure, as described above, uniform connectors can be built with a relatively freely selectable total dimension in both stretching directions.
    [0027] In particular, with both types of housing structure, uniform connectors with a total relative dimension can be built
    Petition 870190096173, of 26/09/2019, p. 32/64
    10/30 freely selectable in both stretching directions. In each type of carcass structure, in particular, both in the first type of carcass structure and in the second type respectively connection elements are provided, respectively corresponding in pairs or suitable for interaction, for purposes of connection preferably in positive union. In principle, any type of positive coupling and / or fitting coupling is suitable, which has a mechanically firm connection in the main plane of the side walls and a minimum resistance against the pulling force perpendicular to it. For the operation of the plug connection, a resistance in the plug direction is significant. A minimum tensile strength can optionally be complemented by other components, such as mounting plates, covers or the like for the necessary fastening. In accordance with a preferred improvement, it is envisaged that all, but at least a part of the connection elements, are designed for connection in positive union. The corresponding connection elements can, in particular, be identical or complementary or conjugated in pairs.
    [0028] The connection elements are preferably provided on the outside next to or on the outside on the side walls. In principle, all suitable types of connection elements are considered for the connection in positive union and / or in union by adjustment force, in particular for the removable connection, in union by adjustment force, for example removing cooperating protrusions in a way complementary with snap action provided with recesses or pins with holes, pushbutton connectors with indentations, pressure connectors with hooks and hook edges, etc. Preferably, connecting elements in the form of cavities externally on the side walls are provided as integral parts of the carcass structure,
    Petition 870190096173, of 26/09/2019, p. 33/64
    11/30 which increases modularity and avoids interference edges, bumps or the like on exposed external sides.
    [0029] Particularly preferably, therefore, additional separate connection elements are provided, which interact with the cavity type connection elements of the side walls. This increases modularity and facilitates the detachment of an individual housing structure from a connector unit already assembled or installed, that is, for repair or maintenance.
    [0030] In a simple, particularly preferred embodiment, a part, preferably all connecting elements, are designed as grooves that extend in the direction of the depth of the housing structure or perpendicular to the mounting plane with a suitable cross section for a spring-to-groove connection, for example T-shaped, dovetailed or similar, on the side walls.
    [0031] In particular, when all connecting elements are designed as grooves, other connecting elements, separated as springs, can be provided in the form of connecting springs for connecting the housing structure based on the grooves. The connecting elements can, in particular, be designed in cross section for a dovetail connection, where the connecting springs are designed with a cross section in the form of a double dovetail, with directed V-wedges in the opposite way.
    [0032] In a preferred embodiment, separate connection springs, suitable for cooperation with the connection elements of the housing structure, are provided for the manufacture of a spring-groove connection. These are preferably designed in cross section for a dovetail connection.
    [0033] Regardless, separate connectors, I preferred
    Petition 870190096173, of 26/09/2019, p. 34/64
    12/30, those with positive union, interact with the connecting elements of the carcass structures.
    [0034] Connectors or connection springs preferably have two latches inversely symmetrical to lock with the housing structure, so that they can be locked in both orientations. For attachment to external components, the separate connectors or connection springs on the main body preferably have two threaded holes, preferably with a tapered screw on at least one main side.
    [0035] When using grooves for spring-to-groove connection, it is also possible to foresee that they are executed of the blind-hole type in the direction of the depth of the carcass structure or perpendicular to the assembly plane, which allows to lock the spring in the desired position. For a stable connection, the grooves, preferably starting at the rear, must extend for at least 33% of the depth of the housing structure.
    [0036] For mounting connector modules known per se, a retention structure known per se can be mounted on the housing structure. For the installation of connector modules known per se, as an alternative, it can be provided that, for each receptacle on both internal sides of the longitudinal side walls, respectively, first and second opposing positive union recesses are provided, which interact to lock with of a connector module. Thus, the connector modules known per se can be locked and aligned directly on the housing structure, without the need for another intermediate structure, such as the usual articulated structure already known.
    [0037] To close and, optionally, also to seal the lines, a properly sized cover can be fixed, alternatively to two rear parts, also on the rear side of the
    Petition 870190096173, of 26/09/2019, p. 35/64
    13/30 carcass structure, being preferred in this case, cable outlets with cable passage washers. Preferably, the rear parts or the cover simultaneously hold the connection elements separate or integrated in the direction of depth or in the direction of insertion.
    [0038] In particular, the invention makes it possible for two connector units composed essentially of housing structures (and conventional connector modules), to interact respectively without another connector housing that surrounds the housing structure or similar, for the plug-in connection of connector modules. The two connector units that serve as the corresponding plug-in connectors and plug-in connectors can be mounted, in particular, by means of identical housing structures.
    [0039] The carcass structures can be made of plastic, in particular polycarbonate or fiber-reinforced plastic, preferably by injection molding, where at the same time additional electrical insulation is obtained. If an EMV shielding of the connector unit is required, this will be achieved, for example, through the appropriate coating technology. Of course, the housing structures, depending on the requirements, can be made in part or entirely of metal. In the case of metal housing structures, in particular, production made using the pressure molding process, for example aluminum, zinc or suitable alloy, in particular with aluminum and / or zinc, is taken into account, since the structures carcass are composed of one or more molded parts. Metal housing structures allow protective earthing or better signal integrity by inherently better shielding. It can be provided inside the metal housing structure, a connection or a terminal to connect the housing structure with a PE protective conductor.
    Petition 870190096173, of 26/09/2019, p. 36/64
    14/30 [0040] As additional components, separate mounting parts, in particular mounting brackets and / or mounting plates, which cooperate with the connecting elements of the side walls, can be provided in particular to secure the connector unit at the respective connection point, such as a machine part, switch cabinet or similar. In principle, additional components are needed only for these functions, which cannot by themselves make the appropriate housing structure or connector modules.
    [0041] For example, locking parts or locking means that can be fixed on the housing structures, such as locking handles or the like, for securing two connected connector units. For mechanical locking of the plug connection, 1 or 2 loop locks can be used, for example according to the Han-Easy Lock® principle (see catalog above), knee lever locks or screw locks, bayonet locks etc. The cooperating locking components can be provided in complementary or assembly parts. However, suitably adapted locking components, for example locking handles, can also be placed directly on the connection elements of the housing structures. In this way, any desired locking can also be mounted modularly in a connector unit of the housing structure.
    [0042] Preferably, each housing structure envisaged as a basic module or the first type of housing structure has an even number (2 xn, with n as an integer) of identical receptacles for up to 2n connector modules, in particular four , six or eight receptacles, for attaching connector modules. In this case, the receptacles can be designed specially adapted for connector modules of the Han-Modular® system
    Petition 870190096173, of 26/09/2019, p. 37/64
    15/30 mentioned above, which provides more than 50 different modules for different means of transmission and in different connection techniques. [0043] In particular, the optional housing structure of the second type can have exactly two receptacles for a connector module, in particular half the number in comparison with the housing structure of the first type. The receptacles are preferably arranged so that the assembled connector modules have their main extension transversely to the longitudinal sides of the housing structure. The dimension in the direction of extension of the width or the longitudinal sides, therefore, is preferably dimensioned with the dimension of the narrow sides of the connector modules, that is, the connector modules are preferably located with their longitudinal side parallel to the narrow side of the housing structure. .
    [0044] In addition to the modular system, the invention also naturally refers to individual housing structures, as such, since this allows the second stage of modularity (as in the housing plan) in the modular system. Each carcass structure has at least two identical receptacles for respectively a connector module within the carcass structure, two parallel side walls, which define the width of the structure and perpendicular to it, two parallel side walls which define the height of the structure. [0045] The module-shaped housing structure, in the sense of the invention, is characterized by the fact that the width of the structure is essentially a multiple N of the height of the structure, optionally adding an assembly clearance, with N being an integer , in particular from 1 to 8, preferably with 1 <N <4, particularly preferably 2 <N <4; all side walls have connecting elements, in particular for the positive union connection, where respectively a connecting element of a wall la
    Petition 870190096173, of 26/09/2019, p. 38/64
    16/30 teral corresponds to a connecting element of a wall perpendicular to it; and that the connecting elements are arranged in relation to each other, according to a grid distance, so that several housing structures are connected modularly to each other by means of their connecting elements to form a connector unit.
    [0046] The grid distance can be twice the distance to the boundary surface of the adjacent side wall. This applies when, in each case, only one connecting element is centrally arranged on the side wall, which defines the height of the structure. This applies in particular to the smallest housing structure and / or to the housing structures provided as a basic unit or basic module. In the case of the second largest structural module or a longitudinal side wall with two connecting elements, the grid distance corresponds to the distance between two adjacent connecting elements on the longitudinal side wall.
    [0047] The invention also relates to a connector unit comprising a plurality of connector modules for lines such as cables, flexible tubes or the like, optionally also for different means of transmission, in particular for electric lines, in which this unit is composed of at least two carcass structures according to one of the previous embodiments. Thus, the or all of the connector modules are housed in one of the housing structures and the housing structures are attached to each other by means of their connecting elements and connected forming a unit. Each connector unit can optionally, depending on the selection of built-in connector modules, represent a plug connector or a corresponding plug connector. The invention also relates to the use of carcass structures according to one of the previous embodiments for the design

    17/30 production of connector units, in particular rectangular connectors, for lines, in particular electrical lines, but also for optical, liquid, gaseous or other means of transmission. Other advantageous characteristics and effects of the invention are explained in more detail below, without limiting the generality of the description above, based on two examples of embodiment with reference to the accompanying drawings, where:
    [0048] figure 1 is a perspective view of an exemplary connector unit, which consists of several housing structures of a first and a second type;

    [0053] figure 8 shows an exemplary plug connector unit made of a housing structure according to figures 6-7A, 7B in perspective view; and figure 9 shows a perspective view of a connection spring for molar connection of the housing structure according to figures 6-7A, 7B. In all drawings, equal reference signs designate

    18/30 equal characteristics or characteristics with equivalent constitution or equivalent effect. For convenience, some consistent features will not be reassigned.
    [0054] figures 1-2 show a connector unit 10 of a purely exemplary configuration of the rectangular connector type, which is composed of the first housing structure 11 and the second housing structure 12 and two side mounting flanges 13. Only two types of housing structures 11,12 offer high modularity in the construction of the connector unit 10. Each of the housing structures 11, 12 is designed as a hollow structure with four side walls arranged in a rectangular shape, successively at right angles to each other 14, 16 and open at the front and rear. On the front side, the plug-in connection is made on the mounting plane (plane perpendicular to figure 5) with another connector unit (not shown). Two parallel side walls 14 define the width of the structure B1 or B2 of the housing structure 11 and 12 and the other two parallel side walls 16, the height of the structure H of the housing structure. The vertical extension directions of the frame width B and the height of frame H cover the mounting plane perpendicular to the depth T of the frame structure 11, 12.
    [0055] In the case of two frame structures 11, 12, the frame width B1, B2 is essentially a multiple N of the frame height H, with N being an integer. Mathematically, B1, B2 and H are congruent in relation to the smallest dimension unit selected, here H. In the first frame structure 11, the structure width B1 is technically exactly 2 times the height of structure H plus a small predetermined mounting clearance a few tenths of a millimeter to facilitate assembly. In the second housing structure 12, the width of structure B2 is technically identical (excluding manufacturing tolerance) to the height of structure H, in this case no leaves
    Petition 870190096173, of 26/09/2019, p. 41/64
    19/30 ga of assembly must be provided. The height of frame H represents, in this case, the basic unit or the smallest unit for design and is identical in the two frame structures 11, 12. Figures 1 to 5 also show, by way of example, in each frame structure 11 , 12, suitable connecting elements 20 for modular assembly, which are provided externally on the four side walls 12. In this case, 20 slots for positive connection are provided as connecting elements. Basically, each of the connection elements 29 corresponds to a side wall 14 or an associated connection element 16 of a side wall 16 perpendicular to it, so that both can fit or possibly interact using a separate connector piece. In the example according to figures 1-5, all the grooves are designed identically as connecting elements 20.
    [0056] The connecting elements 20 are arranged along the circumference or in both extension directions of the width B1, B2 and the height in relation to each other according to a predefined dimension R, so that several frame structures 11 , 12 are connectable to each other based on their connecting elements in a modular way and in each of the four spatial alignments or next to each side wall 14, 16. Thus, the user can use the carcass structures 11,12 as components of a module to form a connector unit in almost any desired project. Other fastening parts, such as mounting flanges 13, can be equipped with connectors 23 for modular construction. In the case of the first housing structure 11, in the example shown, two connecting elements 20 are provided on the longitudinal side walls 14 at the grid distance R in relation to each other. On the narrow sides 16, a connection element 20 is mounted or incorporated exactly centrally. The connecting elements 20 shows
    Petition 870190096173, of 26/09/2019, p. 42/64
    20/30 ram in relation to the boundary surface of the vertically adjacent side wall 14 and 16, the grid distance ie 1/2 R. Not shown, but possible, is a larger number of connecting elements 20 arranged modularly in each side wall 14, 16, for example with a shorter grid distance or larger carcass structure 11, 12. The longitudinal side walls 14 have a number of connecting elements mxn 20, preferably with m even, where n corresponds to the number of connecting elements 20 on the narrow side walls. The integer value m corresponds to the dimension ratio B1: H or B1: B2 (since B1 = H).
    [0057] By adequately adapting the side walls 14, 16 with dimensions B1, B2 Module H (possibly with addition of mounting clearance) in combination with the grid-arranged or modularly arranged 20 connecting elements, the modular principle or modularity for the assembly of the frame structure 11,12 as illustrated by an example in figure 2. All four side walls 14, 16 can be used respectively for connection or assembly, so that the configuration in both directions of assembly plan length is freely selectable, with each total width of Module H and each total height of Module H (with H or B2 as the smallest unit).
    [0058] The connection technology not shown in detail in figure 1-2 is illustrated in figures 3-5. The connecting elements 20 always extend in parallel in the direction of the depth T or in the direction of insertion of the connector unit 10 and are designed as grooves for a dovetail connection or back pressure generation. For fixing two frame structures 11; 12, an adequate number of connecting springs 22 is provided, which fit in half of the cross section respectively in the elements
    Petition 870190096173, of 26/09/2019, p. 43/64
    Groove-like connection 21/30 on the side walls 14, 16, so that the other half in the opposite groove or connecting element 20 of the housing structure to be connected 11; 12 is housed. The connection springs 22 are designed accordingly as elongated molded pins or guide pins with a cross section in the shape of approximately |> <| -. Thus, the connecting springs 22 have opposite sides parallel to the V-shaped narrowing in the longitudinal direction, which are engaged from behind by the dovetail shape of the cross section of the connecting elements 20 (not shown), for achieve positive union.
    [0059] Connection springs 22 are protected against displacement in the depth direction. This is done, on the one hand, respectively by a cover on the rear side 40 or zipper and, on the other hand, by the blind hole type configuration of the grooves that serve as connecting elements 20 and end from the end on the rear side extended in more than 40% of the depth within the respective side wall 14, 16, that is, they do not exceed the entire depth. For locking by means of the lid 40, a locking shoulder 25 is provided on one side of the connection spring 22, which is fixed in a corresponding receptacle 42 with clearance in the lid. The cover can be fixed, for example, by means of a screw connection through the corresponding holes 44 with the corners of the housing structures 11, 12. On the inside of the cover 40, a circumferential seal (not shown) for the front edges side walls 14, 16 can be provided. On the cover wall 40, the most different means of cable entry can be made (not shown). For this purpose, and for the effective lines, the corresponding free space 46 is planned within the carcass structure 11, 12.
    [0060] Figures 3-5 show several identical receptacles, for example
    Petition 870190096173, of 26/09/2019, p. 44/64
    22/30 example four receptacles 30a, 30b, 30c, 30d in the first housing structure 11 for respectively a connector module 18 inside the housing structure 11. (In figures 1-5, the same connector module 18 is always shown for illustrative purposes only, where several connector modules known per se and different connector modules are used 18) All connector modules 18 thus have, for example on their narrow sides, externally on the plastic insulating bodies, fixing interfaces arranged in an identical way. These modular fastening interfaces are intended for locking with previously known retaining structures (not shown) and can, for example, comprise several latching lugs 19A; 19B, coupling hooks or the like. In each receptacle 30a, 30b, 30c, 30d of the two frame structures 11, 12, respectively, compatible means are provided for fixing in positive union, with the fixing interface of the connector module. Figure 5 shows, for example, first and second positive union recesses 31, 32 with an intermediate coupling shoulder 33. The rectangular positive union recesses in this case 31, 32 face each other in parallel and are provided on the inner wall of the side walls that extend in width 14,
    16. The first positive coupling recesses 31 flow outwards on the rear side to allow the insertion of the connector module 18, whose front hooks 19 B engage the second positive coupling recess 32 and are fixed by the coupling shoulder 33 against displacement in the insertion direction. Through the positive union recesses 31, 32, the connector modules 18 are immediately locked in the housing structure 11,12 against displacement against the insertion direction, properly aligned and removably connected to the housing structure. The number of receptacles 30a, 30b, 30c, 30d is preferably an even number in the two structures
    Petition 870190096173, of 26/09/2019, p. 45/64
    23/30 ras of carcass 11, 12.
    [0061] All components of the modular system, in particular the housing structures 11, 12, can be made of plastic at low cost, in which technical plastic with high resistance to flexion, in particular plastic reinforced with fiber, is preferred for purposes of rigidity against use. Other system components, such as mounting parts with various locking means for the connector unit 10, mounting plates for fixing to equipment or machines, etc. they are not shown, but are apparent to those skilled in the art.
    [0062] In the example shown in figures 1-5, only two basic types of carcass structures 11,12 are shown, in which naturally the system is even more scalable, for example with a height direction compared to the first structure of housing of the third type folded with square cross section with doubled height 2H and the same width B1, etc. All housing structures are modularly compatible and can be combined as desired.
    [0063] Through the modular system that is expanded according to the invention by an additional level of modularity, all conceivable geometries of connector units 10 can be produced quickly, easily and economically with some types of housing structures 11, 12. The connector sets 10 thus constructed can be used in all fields, especially in industrial applications, for example as a central plug-in connector unit to supply and control a machine, as a point of separation between relatively moving parts, as in connection elements for power transmission current, in switch cabinets and other equipment, etc. Figures 6-9 show a second preferred embodiment of a housing structure according to invention 211 for the construction of
    Petition 870190096173, of 26/09/2019, p. 46/64
    24/30 connectors 210 or a plug connector connection (figure 8). An essential difference from the first example of embodiment is that the housing structure 211 is essentially composed of three molded parts produced separately, for example, in metal die casting or plastic die casting. [0064] Figure 6 shows the three main components: a front part in the form of structure 211 A, which forms the fitting side of the housing structure 211 and two rear parts 211B, 211C that must be joined perpendicularly to the insertion direction or depth T, which form the part of the finished carcass structure 211, away from the locking side (cf. Figures 7A, 7B). In the internal space of the front in the form of structure 211A - analogous to figures 3-5 - several housing areas 230a-230d are provided for each connector module 18 (not shown here), so that the known connector modules 18 in front part 211A can be mounted. In the example according to figures 6 to 9, a separate retaining structure (not shown) for the connector modules 18 is mounted on the front part 211 A for this purpose. For example, it is possible to provide a retention structure according to figure 4 from EP 2 537 212 B1, the relevant teaching of which is included here. This retaining structure forms a receptacle in each of the housing areas 230a-230d. On the front side and on the inner side of the side walls 216, which specify the height of structure H, a pair composed of a centering spigot 250 and a corresponding centering receptacle 252 is provided in an inverted image. Centering spigots 250 and the associated centering receptacles 252 facilitate the production of the plug-in connection from two plug-in connector units 210, which respectively form plug-in connectors and corresponding plug-in connectors (see figures 7A-7B). In addition, on both sides of the
    Petition 870190096173, of 26/09/2019, p. 47/64
    25/30 large side walls 214 of the front part 211, respectively centrally a receptacle 254 is provided for a label 256.
    [0065] Outside all the side walls 214, 216 of the front part 211A, according to the invention, according to grid dimension R, the first connection grooves 220A extending in the direction of the depth T Here, too, several housing structures 211 are modular based on their connecting elements and can be connected to each other in each of the four spatial alignments or on each side wall 214, 216 (see figure 8). The first connection grooves 220A cooperate together with the second aligned connection grooves 220B on the two rear parts 211B, 211C with a connection spring (figure 9) to produce a spring-groove connection between two or more frame structures 211.
    [0066] At least in the second connection slots 220B of the rear parts 211B, 211C, it is also provided a coupling recess 221, which forms a coupling edge on the rear side to enable one of the two symmetrical coupling tabs to be engaged respectively mirror 225 of the connection spring (see figure 9) in the direction of stretching or direction of depth T. The connection spring 222 is shown in more detail in figure 9. It comprises at one end the two mirror-symmetrical latches 225. The locking tabs 225 have, respectively, on the outside a recess 227, which is aligned in an assembled arrangement with a corresponding recess 217 of the rear parts 211 B, 211 C and allows a release of the locking tabs, for example, by using a screwdriver. In the main body of the connection spring 222, two through threaded connection holes 228 are also provided, which may have a conical head screw 229 on at least one side. Threaded connection holes 228 allow fixing
    Petition 870190096173, of 26/09/2019, p. 48/64
    26/30 of the connector unit 210 on any surface, for example, in a switch cabinet or on a mounting plate.
    [0067] In addition, the connection spring 222, analogously to the first example of embodiment, to produce the molar-groove connection, has V-shaped narrows 224 in the cross section arranged opposite on both sides. The nips 224 cooperate with the longitudinal edges of the grooves 220A, 220B and allow a robust connection of two opposite housing structures 211 (see figure 8).
    [0068] For fixing the rear parts 211B, 211C on the front part 211 A, threaded connection holes are provided on the rear parts 211B, 211C, respectively in the corner, and threads (not shown) on the front part 211 A. Perpendicular to the direction of insertion, the two rear parts 211B, 211C can also be fastened together by screw connection or other suitable firm connection. In the internal space between the rear parts 211B, 211C, a strain relief device can be provided.
    [0069] In the example according to figure 6, the strain relief device comprises an upper strain relief part 270A and a lower strain relief part 270B, which can be of the same construction. The strain relief parts 270A, 270B may have elastically deformable areas, similar to honeycomb type, according to the principle of the utility model DE 20 2017 101 483 IU. The strain relief parts 270A, 270B, after connecting the upper rear 211B to the lower rear 211C, generate a clamping force on the cables to be connected to the connector modules, respectively (not shown). However, it is not high clamping force is required, as with a suitable design of the strain relief parts 270A, 270B sufficient relief can already be achieved by surface adhesion in a plastic pairing

    27/30 suitable.
    [0070] For the creation of wires or cables (not shown), 211B, 211C are also provided on the rear side with fitting on cable feed washers 280. The cable feed washers provided with slot 280 with a cross section approximately in rhombic shapes are preferably used, so that an additional tightening effect on the line can be achieved by connecting the rear parts 211B, 211C by suitable starting chamfers 282 due to the shaping of the sides of the cable feed washers 280, which are in acute angle to each other. In this case, four outputs for lines are shown, for example, in which less than four cable outputs and / or different output diameters are also possible.
    [0071] In addition to the cable feed washers 280, there are provided between the main parts of the housing structure 211, that is, the front part 211A and the rear parts 211B, 211C respectively suitable seals. In the example shown here (figure 6), the seals are produced, for example, entirely on the strain relief parts 270A, 270B. Separate seals can also be provided between the front part 211A and the two rear parts 211B, 211C. Based on the seals, the connector unit 210 is sealed at least against dripping water and, optionally, against splashing water. Preferably, connector units 210 are designed to be splash proof and optionally resistant to water jets. Also on the connector side, a surrounding seal (not shown) can be provided on the front side of the front part 211 A.
    [0072] Figures 7A-7B illustrate the interaction of two connector units 210 as plug connectors and corresponding plug connectors (in this case, for example, without connector modules and with only a connection spring 222).
    Petition 870190096173, of 26/09/2019, p. 50/64
    28/30 [0073] Figure 8 shows, as an example, an arrangement with three connector units 210, which are connected to each other to form a plug connector connection. When using this connector set consisting of 210 connector units, non-interchangeable contact safety as compared to conventional connectors is enhanced. The plug connector and the corresponding plug connector in a plug connector set suitably composed of 210 units are inherently torsion-proof, and / or non-interchangeable contact proof.
