Description

Technical Field

[0001] The invention relates to a retaining frame for a plug-in connector for installation in a metal plug-in connector housing and for protectively grounding the plug-in connector housing and for accommodating similar and / or different modules, wherein the retaining frame is composed of at least two different materials, at least one of which is electrically conductive, wherein the retaining frame has a basic frame and at least one cheek, wherein the basic frame is implemented as a die-casting, and wherein the at least one cheek is composed of a spring-elastic sheet. The invention also relates to a plug-in connector having such a retaining frame and an electronic device. Background Art

[0002] Such holding frames are used, for example, for modular application of modules, also referred to as contact inserts, to plug connectors. One or more modules or contact inserts can be arranged on such holding frames so that they can be inserted together with the holding frame into a plug connector part or into a housing of the plug connector and connected to the housing via the holding frame. In this way, contact inserts can be combined with one another in a modular manner and arranged in or on the plug connector part via the holding frame.

[0003] Such modules can have, for example, one or more electrical contacts. In this case, the module is connected to the electrical wires leading to the plug connector on the one hand and forms plug contacts on the other hand, by means of which the plug connector can be plugged into a mating plug connector part to achieve electrical contact.

[0004] The advantage of these modular modules is that the plug-in connectors can be combined flexibly and can therefore be used in a variety of ways.

[0005] When the module is introduced into the holding frame, the module needs to be held on the holding frame before the holding frame and the module can be mounted together, for example, on a plug connector. To this end, in the holding frame disclosed in DE 10 2012 110 907 A1, a first holding frame part has a recess for accommodating the protruding elements of the module, and a second holding frame part can be attached to the first holding frame part so as to block the protruding elements in the recess in this way and thus lock these protruding elements on the holding frame.

[0006] In the holding frame known from DE 20 2012 103 360 U1, two recesses are provided in the frame wall. The protruding element of the module can be snapped into the first recess on the upper edge of the frame wall, while the pin-shaped projection of the module can snap into the second recess in the form of an opening.

[0007] As shown in FIG. 13 , DE 10 2013 113 975 B4 describes a holding frame 100 for a plug-in connector having at least one cheek 16, which has a rectangular basic shape. Thus, the cheek 16 here has two opposite long edges, namely a first edge and a second edge, and two opposite short edges at right angles to each other, namely a third edge and a fourth edge. The two cheeks 16 are arranged oppositely on the basic frame 10, wherein the module 200 is held on the basic frame 10 by the cheeks 16. The cheeks 16 are flat over their entire extension, so that the cheeks 16 each extend only in one plane. Summary of the invention

[0008] The object of the present invention is to provide a holding frame, a plug-in connector and an electronic device, in which the fixing of the module in the holding frame can be further improved.

[0009] The solution of the present invention to achieve the above-mentioned object is characterized by the independent claim. The preferred technical solution and advantageous improvement of the present invention refer to the dependent claims.

[0010] The holding frame according to the invention is characterized in that the at least one cheek has a trapezoidal tapering.

[0011] Due to the tapering of the trapezoid, the cheeks (also called wall segments) are no longer rectangular. Due to the tapering, the two opposite outer edges of the cheeks are not parallel to each other, but at an angle to each other. In the direction of the tapering, the two outer edges approach each other. Due to the tapering, the cheeks have different widths over the length of the cheeks, so that the cheeks no longer have a continuous width like rectangular cheeks. This tapering makes it possible to achieve uniformly distributed bending stresses over the length of the cheeks and thus uniform deformation of the cheeks over the bending length of the cheeks when inserting and removing the modules from the inner cavity of the basic frame. In addition, compared with the use of rectangular cheeks with constant width, greater elastic deflections can be generated without plastic deflections. When the cheeks perform elastic movements during the insertion and removal of the corresponding module, a uniform stress characteristic curve can be achieved over the length of the cheeks due to the tapering. The tapering of the trapezoid reduces the spring stiffness of the cheeks made of spring elastic sheets. Under the same deflection, the pressing force can be reduced, so that the insertion force required to introduce the module into the holding frame can be further reduced. Furthermore, due to the tapering, material can be saved on the cheeks, thereby saving material in areas that are not required for the cheek function, preferably material for fastening the module to the basic frame.

[0012] The at least one cheek preferably has a fixing area for holding the module, wherein at least one cheek preferably tapers in the direction of the fixing area in a trapezoidal shape. Therefore, the cheek preferably has a minimum width directly adjacent to the fixing area. Therefore, when the module is introduced directly near or in the fixing area, the cheek can have a greater deflection, thereby simultaneously achieving a better rear clamping and thus achieving the clamping of the fixing area on the module. With this tapering, the elasticity of the cheek is improved in the direction of the fixing area, so that a certain form of flexible joint can be formed on the cheek. The cheek is formed as a spring elastic and can therefore be made of a spring sheet, for example. In this way, when the module is introduced, the cheek mounted on the basic frame can be ejected outwards from the inner cavity of the basic frame with its fixing area so that the module is introduced into the inner cavity. When the module is positioned in the desired position in the inner cavity of the basic frame, the fixing area of ​​the cheek can rebound or rotate toward the inner cavity of the basic frame again, so that the fixing area of ​​the cheek can keep the module in its position.

[0013] The fixing region is preferably constructed on a head region of at least one cheek, which is positioned on the end of the cheek opposite to the bottom region. Thus, the fixing region and the bottom region of the cheek preferably have a distance as large as possible.

[0014] The at least one cheek can have a middle section between the bottom area and the head area, wherein the middle section can gradually decrease in the shape of a trapezoid from the bottom area to the head area and can be reversibly deformed. By this gradual taper of the trapezoid, a uniform deformation of the cheek, especially in the range of the middle section, can be achieved within the bending length of the cheek when the module is inserted into and removed from the inner cavity of the basic frame. This deformation is reversible, which means that an elastic deformation of the middle section can be achieved instead of a plastic deformation. Due to the gradual taper of the trapezoid, the middle section forms a deformation section. Therefore, in the region of the deformation section, the cheek tapers in the shape of a trapezoid. The deformation of the cheek preferably occurs only in the middle section, not in the head area or the fixing area, nor in the bottom area of ​​the cheek. Due to the gradual reduction from the bottom area to the fixing area or the head area, the bending stress of the cheek can be reduced from the bottom area to the fixing area. The bottom area can form a clamping position of the cheek on the basic frame, especially on the receiving section of the basic frame. Since the width of the cheeks is gradually reduced from the clamping position (bottom area of ​​the cheeks) by the trapezoidal taper, a uniform stress characteristic curve can be achieved over the length of the cheeks during the elastic movement of the cheeks during the insertion and removal of the corresponding module. By means of this taper, the elasticity of the cheeks is increased in the direction of the head area, so that a kind of flexible joint can be formed on the cheeks. The area of ​​the middle section is preferably much larger than the bottom area and the fixing area of ​​the cheeks when viewed along the length of the cheeks. Compared with the middle section, the bottom area and / or the head area can have a constant width, so that it can be provided that the trapezoidal taper is formed only in the middle section. The trapezoidal taper is preferably carried out over the entire length of the middle section.

[0015] The two opposite outer edges of the cheeks, which are not parallel to each other but extend towards each other (so as to taper in the shape of a trapezoid), can be straight lines. However, it is also possible that the outer edges of the cheeks extending along the middle section have a curved shape. The curved shape of the outer edges can further improve the distribution of bending stresses in the cheeks, thereby reducing the loads acting on the cheeks when inserting and removing the module, while also achieving an optimized elastic effect of the cheeks.

[0016] In order to hold the module, the fixing region can have at least one fixing tongue. The fixing tongues can be designed so that in the installed position they can lie flat on the top side of the protruding element of the respective module, so that the fixing tongue can prevent the introduced module from moving in the direction of introduction of the module into the basic frame in the opposite direction to the direction of introduction of the module. At least one fixing tongue is preferably formed so that it protrudes from the main extension plane of the cheek.

[0017] In order to achieve greater stability when holding the module in its introduced position in the basic frame, the fixing area of ​​the cheek has two fixing tongues, so that the two fixing tongues can lie simultaneously on the top side of the protruding element of the corresponding module. The two fixing tongues of the fixing area of ​​a cheek can be symmetrical to each other. However, the two fixing tongues can also be designed to be asymmetrical to each other.

[0018] The two fixing tongues of the fixing area of ​​a cheek can be arranged on the outer edges of the cheeks arranged oppositely. The two outer edges preferably limit the corresponding cheeks to the outside. By being arranged on the outer edges, the fixing tongues can be arranged in the form of two wings on the cheeks.

[0019] The fixing tongue is preferably bent in the joining area of ​​the respective outer edge. Preferably, the fixing tongue is bent out of the main extension plane of the cheek. Preferably, the fixing tongue can be bent in such a way that it forms an angle α≥90° with the outer edge of the cheek. Particularly preferably, the fixing tongue can be bent in such a way that it forms an angle α≥180° with the outer edge of the cheek.

[0020] Preferably, the length of the at least one fixing tongue is at least three times the thickness of the cheek. The thickness of the cheek is the thickness of the cheek made of the spring sheet. It has been shown that a particularly good holding property of the fixing tongues for holding the module on the basic frame can be achieved if the length of each fixing tongue is at least three times the thickness of the cheek. The length of the fixing tongue is in the main extension direction of the fixing tongue.

[0021] The at least one cheek can be arranged on a receiving section constructed on the side wall of the basic frame in the installation position, wherein the receiving section can have an opening for accommodating a protruding element of a module introduced into the inner cavity of the basic frame, wherein the opening can be at least partially covered by the fixing area of ​​the cheek in the installation position of the cheek. The cheek and preferably a plurality of such cheeks can be arranged on the basic frame. Each module inserted or introduced into the basic frame can be held or fixed on the basic frame by two oppositely arranged cheeks, for example. The installation position refers to a position where the cheek is arranged on the basic frame and the module introduced into the inner cavity of the basic frame can be held by the cheek. Preferably, each receiving section in the plurality of receiving sections is formed on two opposite side walls of the basic frame, and the cheeks can be arranged on these receiving sections. The receiving sections of each side wall are preferably arranged side by side, thus arranged in a row. The receiving section is preferably formed at least partially on the corresponding side wall of the basic frame, so that the receiving section can form a limited receiving area for the cheek. Each cheek arranged on the basic frame corresponds to a receiving section, so that each cheek can be placed in a receiving section respectively. Each receiving section can preferably have an opening respectively, which can be at least partially covered by the fixing area of ​​the cheek corresponding to the receiving section in the installation position of the cheek on the basic frame. The opening is preferably constructed as a notch on the basic frame or on its side wall. The opening preferably extends into the basic frame from the upper edge of the basic frame. Through these openings, the cheeks can establish an operative connection with the module, in particular with the protruding elements of the module, so that the module is kept in the inner cavity of the basic frame. For this purpose, the protruding elements of the module extend into the corresponding openings. In the installation position, these openings can be at least partially covered by the fixing areas of the corresponding cheeks, so that the cheeks can cover or bridge a protruding element of the introduced module with their fixing areas respectively at the end side.

[0022] In order to form a code for introducing the module in the correct position, the opening formed on the first side wall of the receiving section can have a width greater than the opening formed on the second side wall of the receiving section. The two protruding elements constructed on the module preferably also have different widths, so that the module can only be introduced in the following way: the wider protruding element of the module is introduced into the wider opening of the receiving section, and the narrower protruding element is introduced into the narrower opening of the receiving section. In this way, it is possible to prevent the module from being inserted into the basic frame, that is, the holding frame by mistake.

[0023] The receiving sections are preferably each formed on the outer side of the basic frame facing away from the inner cavity. In the installed position, the cheeks thus preferably rest against the outer side of the basic frame. Preferably, no part or region of the cheeks is arranged on the inner side of the basic frame facing its inner cavity in the installed position. In this way, no complicated bending solutions are required for the cheeks, since it is not necessary to buckle the lower edge of the basic frame onto the cheeks of the invention.

[0024] The at least one cheek is preferably fixed or held by its base region on the receiving section assigned to it and thus on the basic frame. The cheek is therefore preferably not fixed to the basic frame by its head region or its fastening region. The head region or the fastening region is preferably exposed relative to the basic frame in comparison to the base region, so that preferably in the installed position no contact is established between the head region or the fastening region of the cheek and the basic frame.

[0025] The bottom area of ​​the cheek can be fixed on the receiving section or the basic frame in different ways. For example, the fixation can be formed by a snap connection and / or a riveted connection and / or an adhesive connection between the cheek and the basic frame.

[0026] The at least one cheek can have a fixing element on its bottom region, which in the installed position engages with an opening formed in the basic frame. Each receiving section can have such an opening. The fixing element can be designed, for example, as a tongue or a flange, which in the installed position can extend into an opening in the basic frame or in the corresponding receiving section and snap or hook onto it.

[0027] The cheeks can be preferably fixed on the basic frame so that the basic frame has at least one groove-shaped recess into which the bottom area of ​​at least one cheek can be pushed in the installation position. In this way, each cheek can be arranged and fixed on the basic frame individually, thereby being arranged and fixed on the corresponding accommodation section individually. However, in this fixing situation, the cheeks can also be arranged and fixed on the basic frame in pairs and therefore two or more cheeks can be arranged and fixed on the accommodation section assigned to them respectively at the same time. By pushing the cheeks at least with their bottom area into the groove-shaped recess of the corresponding accommodation section, the cheeks can be installed on the basic frame very simply and quickly. This can also greatly simplify the structural scheme of the holding frame. These groove-shaped recesses can form a groove on the basic frame for the cheeks to be at least partially (here with their bottom area) in the installation position. The bottom area of ​​the cheeks that enables it to be pushed into the groove-shaped recess is preferably constructed on the ends of these cheeks.

[0028] The at least one groove-shaped recess is preferably formed on the lower edge of the basic frame. In this way, the cheek can be fixed to the basic frame preferably from bottom to top and pushed into the groove-shaped recess. Therefore, the mounting direction of the cheek on the basic frame is preferably opposite to the insertion direction of the module into the inner cavity of the basic frame, so that the cheek can be pushed into the corresponding groove-shaped recess in the opposite direction to the insertion of the module into the basic frame. The module is preferably introduced into the inner cavity of the basic frame from top to bottom.

[0029] The groove-shaped recesses of the accommodation section constructed on the first side wall can be connected and / or the groove-shaped recesses of the accommodation section constructed on the second side wall can be connected. The groove-shaped recesses constructed on one side wall are preferably arranged in a row one after another. In the case where the groove-shaped recesses constructed on one side wall are connected, these groove-shaped recesses can be constructed as a recess that can span all the accommodation sections of one side wall. Such a groove-shaped recess can extend over more than 2 / 3 of the length of the side wall.

[0030] In order to achieve a functional separation between the base region and the middle section, an offset can be formed in the joining region of the base region and the middle section, so that the base region can extend in a first plane and the middle section can extend in a second plane offset from the first plane. In this way, the base region can be arranged in a groove-shaped recess in the basic frame in the installed position, wherein the cheeks can be guided out of the recess in the installed position at the offset joining region of the cheeks, so that the middle section and the fastening region or head region of the cheeks can be guided along the outside of the basic frame and cannot engage in the groove-shaped recess of the receiving section. Due to the offset in the longitudinal direction of the cheeks, the cheeks are no longer designed to be flat over their entire length.

[0031] The receiving sections can each have a contact surface, against which the inner surface of the cheek facing the interior of the basic frame can rest in the installed position. Since the cheek rests with its middle section on the corresponding receiving section, the cheek can be supported well and positionally locked on the receiving section and on the basic frame. The contact surface preferably faces away from the interior of the basic frame.

[0032] The particularly position-locking contact of the cheeks against the basic frame can be further achieved by the fact that the contact surface of the receiving section can be limited by two oppositely arranged inner edges, wherein in the installed position the outer edges of the cheeks can contact in a form-fitting manner in the region of the middle section of the cheeks against the inner edge of the receiving section corresponding thereto. This reliably prevents lateral displacement of the cheeks, in particular during the introduction and removal of the module, since the cheeks are supported on both sides by the outer edges and their movement is thus limited.

[0033] Furthermore, a marking element can be fixed to each of the cheeks. The marking elements can be marked or can be marked by the user himself. These marking elements can mark the module or its slot in the inner cavity of the basic frame. Particularly preferably, the marking elements can be fixed or fixed to the bottom area of ​​the cheek. The marking element can, for example, be inserted into a groove-shaped recess together with the bottom area so that the marking element is fixed. Furthermore, the marking elements can also be glued to the cheeks. The slots of the modules can be marked with the help of the marking elements without having to increase the necessary structural space of the holding frame.

[0034] Described cheek can be constructed as independent element, also can have two or more cheeks that are arranged on the sidewall to link to each other.In the case, these cheeks that link to each other are preferably integrally formed.

[0035] Particularly preferably, these cheeks are connected in one piece on its bottom area.When two or more wall segments connect to each other, these cheeks can also be fixed on the basic framework faster.

[0036] Another solution of the present invention for achieving the above object is a plug-in connector having a housing, a holding frame arranged in the housing, and at least one module accommodated in the holding frame, wherein the holding frame adopts the aforementioned construction scheme and improvement scheme.

[0037] Another solution of the present invention for achieving the above object is an electronic device having at least one plug-in connector adopting the above-mentioned construction scheme and improvement scheme. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Figures 2 to 7 Each is a schematic illustration of a holding frame 100 which can be arranged in a housing of a plug connector.

[0055] The holding frame 100 has an integrally formed basic frame 10. The basic frame 10 has a first side wall 11, a second side wall 12 arranged opposite to the first side wall 11, a first end wall 13, and a second end wall 14 arranged opposite to the first end wall 13. The two side walls 11, 12 are parallel to each other. The two end walls 13, 14 are also parallel to each other. The end walls 13, 14 form an angle of 90° with the side walls 11, 12. The two side walls 11, 12 and the two end walls 13, 14 together surround or limit an inner cavity 15 of the basic frame 10. It can be arranged along Figure 6 The illustrated insertion direction E introduces the module 200 into this interior 15 and fixes it there.

[0056] Through especially Figure 1a and 1b The cheeks 16 arranged on the basic frame 10 shown are used to fix the module 200. The cheeks 16 arranged on the basic frame 10 are of the same structure. Four such cheeks 16 are arranged on the basic frame 10 shown, two cheeks 16 are arranged on the first side wall 11 and two cheeks 16 are arranged on the second side wall 12.

[0057] The basic frame 10 is made of a different material than the cheeks 16. The basic frame 10 is made of a material that is less elastic than the cheeks 16 and therefore more rigid.

[0058] The basic frame 10 is rigid. The basic frame 10 is designed as a die-cast part.

[0059] These cheeks 16 all adopt elastic construction scheme.These cheeks 16 can be formed by a spring sheet.

[0060] Figure 1a 1 is a plan view of the outer surface 17 of the cheek 16 which faces away from the interior 15 of the base frame 10 in the position mounted on the base frame 10 .

[0061] Figure 1b 1 is a plan view of the inner surface 18 of the cheek 16 which, in the position mounted on the base frame 10 , points toward the interior 15 of the base frame 10 .

[0062] The cheeks 16 each have a bottom region 19, a head region 20, and a middle section 21 located between the bottom region 19 and the head region 20. Viewed from the bottom region 19 toward the head region 20 along the length of the cheeks 16, the middle section 21 has a much larger area than the head region 20 and the bottom region 19. The bottom region 19 is formed on a first end of the cheek 16, and the head region 20 is formed on a second end of the cheek 16 that is arranged opposite the first end.

[0063] In the bottom region 19 , the cheek 16 has a greater width B F In the head region 20, the cheeks 16 have a smaller width B K In the region of the middle section 21 , the cheeks 16 taper in the shape of a trapezoid, wherein the width B of the middle section 21 is M Starting from the base area 19, it tapers towards the head area 20. The width B of the middle section 21 M Starting from the base region 19 , the taper occurs towards the head region 20 , so that a uniform deformation of the cheek 16 over the length of the cheek 16 is achieved during the insertion and removal of the module 200 .

[0064] In the region of the middle section 21, the outer edges 22, 23 of the cheeks 16 are not shown here as straight lines, but rather have a curved shape along the length of the middle section 21, that is, starting from the base region 19 towards the head region 20. However, the two outer edges 22, 23 of the cheeks 16 can also be straight lines. The two outer edges 22, 23 do not extend parallel to each other, but are arranged relative to each other. Starting from the base region 19, the outer edges 22, 23 extend towards each other in the direction of the head region 20, so that the cheeks 16 in the region of the middle section 21 gradually taper in the shape of a trapezoid starting from the base region 19 towards the head region 20.

[0065] An offset is formed in the joining region 24 of the bottom region 19 and the middle section 21 so that the bottom region 19 extends in a first plane and the middle section 21 extends in a second plane offset from the first plane. The first plane and the second plane are substantially parallel to each other.

[0066] The bottom region 19 has two laterally formed shoulder surfaces 25, 26 which, in the position in which the cheeks 16 are mounted on the basic frame, engage in groove-shaped recesses 27 of the receiving section 35 formed on the basic frame 10, see Figure 5 The two shoulder surfaces 25 , 26 project laterally outwards, so that they laterally cover the middle section 21 and the head region 20 or protrude therefrom.

[0067] The base region 19 also has a fastening element 28 which can be snapped into an opening 29 formed in the base frame 10. The fastening element 28 is designed as a tongue cut out of the base region 19 and bent toward the base frame 10. The fastening element 28 in the form of a tongue can be hooked into the opening 29. The width B of the fastening element 28 in the base region 19 is F Build in the center.

[0068] A fixing region 30 is formed on the head region 20, which serves to hold the module 200 introduced into the interior 15 in the interior 15. The fixing region 30 has two fixing tongues 31, 32. The fixing tongues 31, 32 extend toward the interior 15 of the basic frame 10 in the position in which the cheek 16 is mounted on the basic frame 10. The two fixing tongues 31, 32 are respectively formed on one of the two outer edges 22, 23 of the cheek 16. Figure 1a , 1b In the solution shown, the fixing tongues 31 , 32 are bent at an angle α of approximately 90° to the outer edges 22 , 23 of the cheeks 16 . The fixing tongues 31 , 32 thus project from the main extension plane of the cheeks 16 .

[0069] The lower edges 33 of the fixing tongues 31, 32 are substantially straight and are used to place the fixing tongues 31, 32 flat on the protruding elements 210 of the module 200, thereby holding the module 200 in the inner cavity 15 of the basic frame 10. The upper edges 34 of the fixing tongues 31, 32, which are arranged opposite the lower edges 33, are inclined so that the upper edges 34 can form an introduction slope for introducing the module 200 into the inner cavity 15 of the basic frame 10 along the introduction direction E of the module 200. Through this introduction slope, the module 200, in particular the protruding elements 210 of the module 200, can slide along the upper edges 34 of the two fixing tongues 31, 32 during its introduction, so that the cheeks 16 are bent outwards, so that the cheeks 16 are ejected outwards and release the inner cavity 15 of the basic frame 10, so that the module 200 can be introduced into the inner cavity 15 of the basic frame 10 with its protruding elements 210. When the module 200 is introduced into the interior 15, the cheeks 16 can spring back again until they lie flat on the protruding element 210 with their lower edge 33, thereby holding the module 200 in the interior 15 of the basic frame 10. The length of each fixing tongue 31, 32 is preferably at least three times the thickness of the cheek 16 or the cheek piece, thereby achieving particularly good holding properties of the fixing tongues 31, 32 for holding the module 200 in the basic frame 10.

[0070] like Figure 2 As shown, the basic frame 10 has a receiving section 35 for each cheek 16. These receiving sections 35 are formed on the outer side 36 of the basic frame 10 facing away from the interior 15. These receiving sections 35 are formed on the two side walls 11 and 12 of the basic frame 10. In the technical solution shown here, two receiving sections 35 are respectively formed on the first side wall 11 and the second side wall 12.

[0071] Each receiving section 35 has a groove-shaped recess 27 into which the bottom area 19 of the corresponding cheek 16 can be pushed with its two shoulder surfaces 25, 26. Figure 5 As shown, the groove-shaped recess 27 of the receiving section 35 of the first side wall 11 and the groove-shaped recess 27 of the receiving section 35 of the second side wall 12 are respectively connected, so that the recess 27 of the receiving section 35 of each side wall 11, 12 together forms a recess 27 on each side wall 11, 12. The corresponding recess 27 extends over almost the entire length of the corresponding side wall 11, 12.

[0072] The recess 27 of the receiving section 35 is formed on the lower edge 37 of the base frame 10. This allows the cheek 16 to be fixed to the base frame 10 from bottom to top in the installation direction M. The cheek 16 is thus fixed to the base frame 10 opposite to the direction of introduction E of the module 200 into the interior 15 of the base frame 10.

[0073] The receiving sections 35 each have a contact surface 38 above their groove-shaped recesses 27. The contact surfaces 38 are each formed on the outer side 36 of the basic frame 10, wherein the contact surfaces 38 each form a recess on the outer side 36 of the basic frame 10. In the installed position, the respective wall section 16 rests against the contact surface 38 with the section 21 thereof in a planar manner. The contact surface 38 is each bounded by two oppositely arranged inner edges 41, 42, wherein in the installed position, the outer edges 22, 23 of the respective cheek 16 rest against the inner edges 41, 42 in a form-fitting manner. Thus, the inner edges 41, 42 have a curved shape like the outer edges 22, 23. The inner edges 41, 42 preferably have a height such that in the installed state the cheek 16 is flush with the outer side 36 of the basic frame 10. The inner edges 41 , 42 respectively arrange the contact surface 38 of the receiving section 35 offset from the outer side 36 of the basic frame 10 in the direction of the interior 15 of the basic frame 10 .

[0074] Above the contact surface 38, the receiving section 35 has an opening 39, which extends from the upper edge 40 of the basic frame 10 into the respective side wall 11, 12 of the basic frame 10. In the installed position of the cheek 16, the fixing region 30 or the head region 20 of the respective cheek 16 at least partially covers the opening 39. The fixing tongues 31, 32 can extend into the opening 39. In the region of the opening 39, the fixing tongues 31, 32 can fix the module 200 by placing the fixing tongues 31, 32 on the protruding elements 210 of the module 200 that extend into the opening 39, see Figure 6 .

[0075] Especially if Figure 2 and Figure 7 As shown, the opening 39 on the first side wall 11 has a greater width than the opening 39 on the second side wall 12 .

[0076] Figure 3 The mounting of one of the cheeks 16 on the basic frame 10 is shown by pushing the cheek 16 into the groove-shaped recess 27 in the mounting direction M, wherein in particular the two shoulder surfaces 25, 26 of the base region 19 are guided into the groove-shaped recess 27 so as to snap into the groove-shaped recess 27. In the process, the cheek 16 slides with its middle section 21 along the contact surface 38. The cheek 16 is pushed in until the fixing element 28 of the base region 19 hooks into the opening 29 on the basic frame 10, see Figure 4 In this installed position, the head region 20 or the fastening region 30 of the cheek 16 is located in the region of the opening 39 in order to at least partially cover it.

[0077] With the cheeks 16 mounted on the base frame 10, the module 200 can be introduced into the interior 15 of the base frame 10 in the insertion direction E. In the process, the module 200 slides with its protruding elements 210 along the upper edges 34 of the fixing tongues 31, 32, so that it and the fixing area 30 of the corresponding cheek 16 are ejected outwards so that the protruding elements 210 pass the fixing tongues 31, 32. When the module 200 passes the fixing tongues 31, 32, these fixing tongues spring back toward the interior 15 until they lie flat on the protruding elements 210 from top to bottom, see Figure 6 and 7 In this position, the protruding elements 210 are respectively covered by the cheeks 16 corresponding thereto, in particular by the middle sections 21 of the cheeks 16, end-side, cf. Figure 6 and 7 .

[0078] Figure 8 and 9 Shows something like Figure 1a , 1b 2 to 7, in which only the shape of the fixing tongues 31, 32 differs, the fixing tongues 31, 32 being bent at an angle α of ≥180° to the outer edges 22, 23 of the cheeks 16. Figure 8 and 9 In the illustrated embodiment, the fixing tongues 31 , 32 of the cheeks 16 are bent towards each other.

[0079] Fig.10 It is also shown that a marking element 43 is arranged in the region of the cheek 16. The marking element 43 is arranged on the bottom region 19 on the cheek 16. The marking element 43 is fixed to the bottom region 19 of the cheek 16 by an adhesive connection.

[0080] exist Fig.11 and 12 In the illustrated embodiment, the two cheeks 16 arranged on the side wall 12 are connected in one piece. The two cheeks 16 are formed in one piece on their bottom area 19. The cheeks 16 are connected in one piece via shoulder surfaces 25, 26 of the bottom area 19.

[0081] The recess 26 extends over the two receiving sections 35 of the side wall 12 and thus over almost the entire length of the side wall 12. In this way, the integrally formed cheek 16 can be simultaneously pushed with its integrally formed bottom area 19 into the recess 26 and thus mounted on the basic frame 10 or on the side wall 12 of the basic frame 10.
