    - 1 Socket for a multiDole plu-in connection The invention relates to a socket for a multipole plug-in connection, in particular for the electric connection of a motor vehicle trailer to a motor vehicle, comprising a socket housing and a socket cover which is arranged on the socket housing in a pivoted manner, wherein the socket housing provides a plug-in pattern comprising seven contact openings and comprises a base body having a cross section that is circular in at least some sections. Furthermore, the invention relates to a plug-in system comprising a socket and a connector corresponding to the socket. A socket of the initially mentioned type is known from the state of the art, for example from DE 32 12 848 C2 and DE 29 17 952 Al. The socket housings of the known sockets are so-called "round housings", i.e. they comprise a base body, the cross section of which is circular in at least some sections. This kind of socket design has proved to be good in daily practice, especially for reasons of the housing stability and the comparatively large housing space for accommodating electric and/or electronic components as well as because of favorable assembly options. The known sockets are seven-pole sockets, i.e. they comprise seven contact sockets. In the due application case, these ones cooperate with a corresponding number of plug in contacts of a corresponding connector. Herein, the contact sockets are accessible via a respective contact opening. The contact sockets are typically arranged in a circular manner, wherein a centrally placed contact socket is surrounded in a circle by the other contact sockets. This circular arrangement of the contact sockets corresponds to the socket housing which is round, i.e. the cross section of which is circular at least in some sections. Furthermore, thirteen-pole plug-in connections are known from the state of the art. In such plug-in connections, thirteen receptacles are used instead of seven receptacles for each socket. Herein, the thirteen receptacles are also arranged in a circle, wherein four central receptacles are surrounded in a circle by nine receptacles. The connector which -2 corresponds to this is correspondingly designed and provides thirteen plug-in contacts on his part, which are also arranged in a circle and are thus compatible with the plug-in pattern of the sockets. Apart from the above described "round" sockets and "round" connectors, also multipole flat sockets or tabs (flat connectors) are known from the state of the art. In contrast to "round" sockets and "round" connectors, such sockets or connectors comprise rectangular-shaped housings. Accordingly, the above described "round" sockets and "round" connectors are not compatible with such flat sockets or tabs. They are also not compatible because not only the housings have different shapes, but also plug-in patterns which are not compatible with each other are provided. For solving the problem of lacking compatibility, corresponding adapters are known from the state of the art. In the due application case, these ones are inserted between non compatible sockets and connectors, which allows a combination of otherwise non compatible plug-in connections. The o b j e c t on which the invention is based is to propose a novel type of socket which makes use of the advantages of the "round" socket, but is simultaneously compatible with tabs. For a c h i e v i n g this aim, the invention proposes a socket of the initially mentioned type, which is characterized in that six of the contact openings are placed on a common fictive straight line. The socket according to the invention is designed as a "round" socket and thus comprises a socket housing having a base body, the cross section of which is circular at least in some sections. But in contrast to the "round sockets" known from the state of the art, the socket according to the invention does not provide a circular plug-in pattern. Breaking with the known state of the art, the socket according to the invention provides a plug-in pattern according to which six of the contact openings and thus also the contact sockets received by them are placed on a common fictive straight line. In this way, a "round" socket is created which is compatible with tabs known from the state of the art and this without insertion of an adapter which is to be handled separately.
    -3 The design according to the invention proves to be advantageous for several reasons. Thus, the socket according to the invention provides a socket housing which is compatible with tabs and which is much more stable and robust than flat sockets known from the state of the art thanks to its geometric design as "round" housing. Thus, the socket according to the invention is much more resistant to mechanical stresses which may also occur in the due application case, which results in an increased service life in comparison to the state of the art. Furthermore, the socket housing according to the invention allows providing a greater socket space such that there is more space for electricity and/or electronics to be accommodated in the socket housing. Thus, the spectrum of possible applications of the socket according to the invention is wider than the one of conventional sockets compatible with tabs. What is more is another synergetic effect. The socket housing of the socket according to the invention offers sufficient reception space with respect to the arrangement of more than seven contact sockets. In so far, a thirteen-pole socket has a socket housing of the same size with respect to its geometric dimensions. This has the advantage that a retrofitting from a seven-pole plug-in system to a thirteen-pole plug-in system can be easily realized on the motor vehicle by simply exchanging the socket housing, wherein the connections for attaching the socket to the motor vehicle can be used in an unchanged manner. Thus, the mounting effort is reduced to a minimum in case of a retrofitting. Herein, also a retrofitting to a "round" socket having a circular plug-in pattern can be realized in an equally simple way. The socket designed according to the invention furthermore proves to be easy to install. The cross section of the socket base body which is circular in at least some sections provides sufficient space for corresponding connection and/or attachment devices. Thus, the socket housing can be for example provided with corresponding through holes for screwing. This permits an easy installation in so far as for the due installation of the socket on a counterpart, corresponding screws have to be guided through the through holes of the socket housing and be secured on the counterpart, for which purpose the counterpart comprises threaded holes or also corresponding through holes, such that a counter-securing can be realized by means of corresponding female screws. Preferably, a retaining and/or mounting plate which is attached to a vehicle is used as counterpart. Herein, the retaining and/or mounting plate can be attached to the bumper -4 or also to the trailer coupling of the motor vehicle. Thanks to the above described design it is possible to mount the socket housing in a simple manner on the retaining and/or mounting plate or to dismount it in the case of repair or maintenance by releasing the screws which connect the socket housing to the retaining and/or mounting plate. Altogether, the invention proposes a socket which comprises a socket housing of a "round" socket, but provides a plug-in pattern with respect to its contact sockets which is compatible with tabs. Thus, the design according to the invention allows combining a tab with a "round" socket housing without using an adapter which has to be handled separately. A retrofitting to a plug-in system comprising more poles is furthermore possible in a simple manner, also to such a one comprising contact sockets or plug-in contacts arranged in circles. According to another feature of the invention it is provided that a contact opening is spaced from the fictive straight line. This design serves to prevent turning, whereby it is assured that the connector compatible with the socket will not be turned by mistake into a wrong position, i.e. by 1800, and inserted like this into the socket housing. An unintended false contacting of the contact sockets provided by the socket with the plug in contacts provided by the connector will thus be safely prevented. According to another feature of the invention it is provided that the base body of the socket housing carries a contact block, which contact block comprises the contact openings. Herein, the contact block is at least partially rectangular, whereby the geometric compatibility with a tab which can be combined with the socket according to the invention is obtained. Herein, the contact block comprises an extension, which is compatible with an opening width of a corresponding connector, in the direction of the fictive straight line of the contact openings. The result of this geometric design is that the contact block will be at least partially received by the connector in the due application case, such that a positive reception of the connector by the socket will result. A position safe arrangement of the connector within the socket is thus assured. According to a first alternative embodiment, the contact block is made as one piece with the base body of the socket housing. Such a design is in particular advantageous for reasons of tightness against splash water and dirt. According to a second alternative -5 embodiment, the contact block is separate from the base body of the socket housing and in the due application case it is inserted in a replaceable manner into an opening provided by the base body. Such an embodiment offers the advantage of a simplified assembly, in particular in case of a retrofitting or a replacement, since the contact block with the contact sockets held therein can be inserted in a preassembled state into the base body of the socket housing. A preceding cabling of the contact block is also allowed, such that this one can be equipped in a finishing manner in the sense of a preassembly, before this one is inserted into the opening of the base body of the socket housing, which opening is provided for this, for a due utilization. Corresponding lock-in devices are provided for the position safe arrangement of a replaceable contact block in the base body of the socket housing. Such lock-in devices can be for example pivoting lock-in legs which spring out upon insertion of the contact block and spring in again upon arrival of the contact block in the end position, wherein they hold the contact block on the rear side by means of corresponding lock-in prolongations in the deflected state, such that the contact block is supported by the lock-in legs with respect to the base body of the socket housing. According to an alternative embodiment, a sort of support body can also be provided instead of lock-in legs, which support body supports the contact block with respect to a mounting and/or retaining plate in the due application case, such that if in the due application case the connector is plugged into the socket, the contact block will not be pushed rearwards out of the socket housing. The contact block according to the second alternative embodiment which is received in a replaceable manner by the base body of the socket housing can also be designated as contact carrier insert. The socket according to the invention is furthermore characterized by a wall which is carried by the base body and spaced from the contact block while leaving a gap between them. In the due application case, this wall serves as abutment to the connector, such that in combination with the support of the connector obtained by the contact block, a tilt resistant arrangement of the connector within the socket is achieved. Herein, the gap provided between the wall and the contact block serves as guiding gap to guiding prolongations provided on a corresponding connector. This embodiment is advantageous for two reasons. On the one hand, an additional coding protection is provided which counteracts a misalignment of the socket and the connector. On the -6 other hand, a guiding set is provided which permits a safe insertion of the connector into the socket, whereby an intended contacting of the contact sockets on the socket, on the one hand, and the plug-in contacts on the connector, on the other hand, is assured. The dimensions of the socket housing are preferably chosen, such that not only the contact block or the contact sockets provided by this one can be accommodated in the housing. An additional volume space is preferably formed within the socket housing which for example serves to receive additional electronic devices and circuits, for example in the form of micro-switches. Such micro-switches can for example serve to detect a connector which is plugged into the socket in the due application case. If a connector is not properly plugged in, there won't be any operation of the micro-switch, which can be indicated to the user for example in form of a visual and/or acoustic signal. For securing contact sockets which are received by the contact openings of the contact block in the due application case, a corresponding holding device can be provided according to another feature of the invention, for example in the form of a comb. In the due application case, this comb is received by a receiving shaft of the contact block, which shaft extends transversely to the contact openings of the contact block. In the assembled state, the fork-like openings of the comb-like holding device respectively encompass a contact socket arranged in a contact opening of the contact block, such that the position safe arrangement of the contact socket in the contact opening is assured. According to another feature of the invention it is provided that the socket cover comprises a holding claw, which cooperates with a corresponding connector, on its side opposite the articulated attachment to the socket housing. This holding claw serves to secure the position of, i.e. to hold down a connector which has been plugged in the intended manner into the socket housing. An unintended disengagement of the connector from the socket, for example by vibrations which also occur in the due application case, is thus counteracted effectively. Herein, the socket cover is preferably arranged on the socket housing by interposition of a spring, such that the socket cover is under the action of a prestressed spring in the opened state, which in case of a plugged-in connector leads to the fact that the socket cover presses onto the connector inserted into the socket housing under the influence of resilience. Thereby, the -7 connector is fixed in a position safe manner and held not only by the socket housing due to its geometrically compatible design with the socket housing, but additionally also by the spring-loaded socket cover, wherein the socket cover acts upon the connector with its holding claw provided according to the invention. According to another aspect, the invention proposes a plug-in system for a multipole plug-in connection, in particular for the electric connection of a motor vehicle trailer to a motor vehicle, which system comprises a socket of the above described type as well as a connector which corresponds to the socket. Herein, the plug-in system according to the invention stands out in that a retaining plate for receiving the socket housing and an attachment device for arranging the retaining plate on a trailer coupling of a motor vehicle are provided. The socket housing is disposed on the motor vehicle by means of the retaining plate. For this purpose, the retaining plate comprises through bores which serve to guide through fastening means for fixing the socket housing on the retaining plate. Herein, especially screws can be considered as fastening means. A fastening device serves to fasten the retaining plate on the motor vehicle. Herein, it is preferred to place the retaining plate on a trailer coupling of a motor vehicle, for which reason the fastening device is correspondingly designed. According to a particular feature of the invention, it comprises a retaining shackle, on the one hand, as well as a clip-lock on the side of the retaining plate, on the other hand. In the finally assembled state, the retaining shackle encompasses the neck of a trailer coupling, whereby thanks to the interposition of the clip-lock, a safe arrangement of the retaining plate for receiving the socket housing on the trailer coupling of the motor vehicle is assured. The above described embodiment has the advantage of a comparatively simple mounting or dismounting, which in particular favors a retrofitting of a motor vehicle with a socket according to the invention. The socket according to the invention can also be part of an adapter. An adapter in the sense of the invention is a component which is interposed between a socket on the one hand and a connector on the other hand and serves to connect sockets and connectors -8 in an intended way which are principally non compatible with each other. An adapter in this sense therefore comprises a socket side on the one hand and a connector side on the other hand, wherein the socket side of the adapter serves to receive a connector and the connector side of the adapter serves to be received in a socket. It is within the scope of the invention to design the socket side of such an adapter as a socket according to the invention. In such an application case, the socket cover that is disposed in a pivoting manner on the socket housing can eventually be omitted. For the first time, the invention proposes a socket which has a "round" socket housing, but also serves to receive tabs. Thus, for the first time a cross-system socket construction is proposed which has the already described advantages. Hitherto, the experts have assumed that compatibility between flat systems on the one hand and round systems on the other hand is not practicable, for which reason corresponding adapters have been developed. The design according to the invention counters this prejudice, since for the first time a socket having a "round" socket housing which is compatible with a tab is proposed. This enables to insert identical housing base bodies independent from the connector design. On the one hand, this is production-technically advantageous, on the other hand, the mounting or dismounting, in particular in case of retrofitting, is simplified, since one and the same fastening devices can be used on the motor vehicle. Furthermore, a socket retrofitting can take place in a simple manner, if a user wants to have a socket comprising a different plug-in pattern, for example if another motor vehicle trailer having different connector plugs is chosen. Thanks to this, also a retrofitting from a flat plug-in system to a "round" plug-in system becomes in particular possible. A standardization of the plug-in systems is thus advantageously enabled, which besides also helps to avoid the inconvenient use of additional adapters to be handled separately. Other features and advantages of the invention will become apparent from the following description by means of the figures. Herein: Fig. 1 is a schematic perspective view from above of a socket housing of a socket according to the invention; -9 Fig. 2 is a schematic perspective view from below of the socket housing according to fig. 1; Fig. 3 is a schematic top view from above of the socket housing according to fig. 1; Fig. 4 is a schematic plan view from below of the socket housing according to fig. 1; Fig. 5 is a side view of the socket housing according to fig. 1; Fig. 6 is a schematic perspective view from above of a socket cover of a socket according to the invention; Fig. 7 is a schematic perspective view from below of the socket cover according to fig. 6; Fig. 8 is a schematic top view from above of the socket cover according to fig. 6; Fig. 9 is a schematic plan view from below of the socket cover according to fig. 6; Fig. 10 is a schematic side view of the socket cover according to fig. 6; Fig. 11 is a schematic perspective view from above of a holding device which is designed like a comb; Fig. 12 is a schematic perspective view of a connector compatible with a socket according to the invention; Fig. 13 is a schematic perspective view of a retaining plate; Fig. 14 is a schematic perspective view of a retaining shackle and Fig. 15 is a schematic perspective view of a clip-lock.
    -10 Figures 1 through 10 are different views showing the socket 1 according to the invention, wherein figures 1 through 5 show the socket housing 3 and figures 6 through 10 show the socket cover 4. In the due application case, the socket cover 4 is arranged on the socket housing 3 in a pivoting manner, with interposition of a spring which is not further represented in the figures, such that the socket cover 4 is always under the effect of a prestressed spring and permanently aims at pivoting into its closed position, in which the socket 1 is closed. As it is in particular visible in figures 1 through 5, the socket housing 3 comprises a base body 9. This base body 9 has a circular design with respect to its cross section, apart from lateral flat faces 18. Therefore, the socket housing 3 is also called "round" housing. The base body 9 carries a contact block 5. This one provides contact openings 6 which are respectively allocated to a contact socket which is not further represented in the figures. A connector 2 plugged into the socket 1 comprises plug-in contacts 8 which in the due application case pass through the respectively associated contact openings 6 in the contact block 5 and are in electric contact with the respectively associated contact sockets of the socket 1, which are not further represented in the figures. The socket 1 comprises a seven-pole plug-in pattern. Herein "seven-pole" means that the socket 1 provides seven contact sockets in total and thus also seven contact openings 6 are provided which respectively enable the access to the respective contact sockets. On the inner side of the socket housing 3 a housing case 22 is provided, as it is in particular visible in the representation of fig. 2. This housing case 22 serves to receive contact sockets which are accessible through the contact openings 6 and/or other electric and/or electronic components of the socket 1. The base body 9 furthermore carries a top portion which provides a wall 15. Herein, the wall 15 is spaced from the contact block 5 while leaving a gap 16. This gap 16 serves as guiding gap, as it will still be described in the following.
    - 11 Domes 21 formed within the interior of the housing serve to fix the socket housing 3 on a motor vehicle, which domes respectively provide a bore 20, as it is in particular visible in the representations of figures 2 and 4. In the due application case, the bores 20 serve to receive for example respective screws which are screwed with a motor vehicle in the due application case for fixing the socket housing 3 on the motor vehicle. Herein, preferably a retaining plate, such as represented in fig. 13, is used for fixing the socket housing 3 on a motor vehicle. As it is furthermore visible in figures 2 through 4, the socket housing 3 comprises a reduced wall thickness in the area of the flat side faces 18. This design allows creating lateral cable outputs 19 in case of need, in that the reduced wall material in the area of the flat side faces is removed by breaking it out. In this case, the electric connection cables which lead to the contact sockets that are not further represented in the figures can be laterally passed inside the socket housing 3. Alternatively they are passed through the rear side. As it is in particular visible in the representation of fig. 3, six of the contact openings 6 are placed on a fictive straight line 14. These six contact openings 6 are successively placed side by side on this straight line 14. A central seventh contact opening 6 is slightly spaced with respect to this fictive straight line 14 which connects the other contact openings 6 to each other, which fact advantageously leads to a plug-in coding and in the utilization case takes care that a connector 2 compatible with the socket 1 according to the invention cannot be plugged into the socket housing 3 in a position turned by 1800. For a position safe placement of the contact sockets which are in the due application case received by the contact openings 6 of the contact block 5, a holding device in form of a comb 40 can be used, such as it is exemplarily represented in figure 11. In the due application case, the comb 40 is inserted into a correspondingly shaped shaft of the contact block 5, wherein this shaft extends transversely to the longitudinal extension of the contact openings 6, such that the fork-shaped openings of the comb 40 respectively encompass the contact sockets placed in the associated contact openings 6 and thus assure the position safe placement.
    -12 Such a connector 2 which is compatible with the socket 1 according to the invention is represented in fig. 12. This connector is a so called tab, the plug-in contacts 8 of which are arranged in a way that corresponds to the plug-in pattern 7 provided by the socket housing 3. As it is visible in Fig. 12, the connector 2 comprises a connector body 10. A connection part 11 is provided on its side opposite the plug-in contacts 8. Connection cables which are not further represented in the figures are guided through this connection part 11, which connection cables are connected to the plug-in contacts 8 on the side of the contacts. On the side of the plug-in contacts, the connector 2 comprises lateral extensions 12 as well as guiding prolongations 13, wherein the latter are attached to the lateral extensions 12 in an angle of 900. In the due application case, the connector 2 encompasses the contact block 5 provided by the socket housing 3 by means of its lateral extensions 12, wherein the inner surfaces of the lateral extensions 12 are adjacent to the outer sides of the small faces of the contact block 5. Furthermore, the guiding prolongations 13 of the connector 2 engage in the gap 16 between the wall 15 and the contact block 5 of the socket housing. Altogether, a position safe placement of the connector 2 in the socket housing 3 is thus assured on the one hand and a geometric coding security is provided on the other hand. The socket 1 furthermore comprises a socket cover 4, such as it is represented in figures 6 through 10. Herein, ribs 17 serve to the pivoting arrangement of the socket cover 4 on the socket housing 3, which ribs are in particular visible in the representations of the figures 1 and 5. For fixing the socket cover 4 on the socket housing 3 in an articulated manner, an articulated section 23 provided by the socket cover 4 is used, which articulated section 23 is held by the ribs 17 of the socket housing 3 with interposition of a spring in the finally assembled state. The socket cover 4 provides a holding claw 24 which comprises two webs 25, as it is in particular visible in the representations of the figures 6, 8 and 9. In the due application - 13 case, this holding claw 24 serves to fix a connector 2 which is properly plugged into the socket 1 in its position and thus to prevent it from falling out of the socket housing 3 in an undesired manner. Herein, the design of the holding claw 24 or the webs 25 is such that it encompasses the connection part 11 provided by the connector 2 by means of the claw opening 26 formed between the webs 25. The socket cover 4 furthermore comprises cover extensions 27 which get to be placed on the side of the contact block 5 of the socket housing 3 if the socket is not used and which provide for a tight cover of the contact block 5 in particular against splash water and soils. A retaining plate 28, such as it is shown in fig. 13, is preferably used for fixing the socket 1 on a motor vehicle. Herein, the retaining plate 28 comprises a socket section 31 and an angular section 33. The socket section 31 serves to receiving the socket housing 3, for which purpose the socket section 31 provides a cable opening 32 for a rearward outlet of the cable on the one hand and bores for screwing the socket housing 3 to the retaining plate 28 on the other hand. The angular section 33 however serves to place the retaining plate 28 on the motor vehicle, for example on a trailer coupling, for which purpose the angular section 33 provides long hole bores 34. A fastening device which comprises a retaining shackle 29 as well as a clip-lock 30 serves to fix the retaining plate 28 on a trailer coupling of a motor vehicle. The retaining shackle 29 is represented in fig. 14. It comprises a curved section 36 which in the finally assembled state encompasses the arm of the trailer coupling which carries the trailer ball. Threaded sections 35 are respectively provided at the ends of the retaining shackle 29. The clip-lock 30 which is represented in fig. 15 provides circular openings 38 which in the assembled state are adjacent to the arm of the trailer coupling. The threaded sections 35 of the retaining shackle 29 pass through bores 39 formed in the clip-lock 30. On its side opposite the circular openings 38, the clip-lock 30 comprises a supporting - 14 surface 37. In the finally assembled state, the retaining plate 28 has its angular section 33 adjacent to this supporting surface 37 and the threaded sections 35 provided by the retaining shackle 29 pass through the bores 34 provided by this angular section. A screwing is realized by means of corresponding female screws, such that in the finally assembled state the retaining shackle retains the retaining plate 28 safely on the arm of a trailer coupling with interposition of the clip-lock 30. According to the exemplary embodiment shown in the figures, the socket comprises seven contact sockets in total. The invention is not limited to such an embodiment, but also applies to such sockets which provide at least seven contact sockets, i.e. they eventually have more than seven contact sockets. Thus, it can be in particular provided that the socket provides twelve contact sockets in total, wherein it is only of importance with respect to the invention that six of the contact openings provided for the contact sockets in the contact block are placed on a common fictive straight line. Thus, the invention also applies to such embodiments according to which twelve contact sockets are provided which are spaced from each other in two rows, wherein the one row provides five contact sockets and the other row provides seven contact sockets.
