Description

The invention relates to a holding frame for a connector for installation in a metallic connector housing and for protective grounding of the same, as well as for accommodating similar and / or different modules, the holding frame being formed from at least two different materials, at least one of which is electrically conductive the holding frame has a base frame and at least one cheek part, the base frame being designed as a die-cast part, and the at least one cheek part being made of resilient sheet metal. The invention also relates to a connector with such a holding frame and an electronic device.

Such holding frames are used for the modular use of modules, also called contact inserts, for example on connectors. One or more modules or contact inserts can be arranged on such a holding frame in order to be inserted together with the holding frame into a housing of a plug connector part or a plug connector and to be 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 a connector part via the holding frame.

Such modules can have one or more electrical contacts, for example. In this case, the modules are connected on the one hand to electrical lines that are fed to a plug connector and on the other hand form plug contacts via which the plug connector can be inserted into engagement with a mating plug connector part for electrical contact.

Such modular modules offer the advantage of flexible combinability and thus variable usability of connectors.

If modules are inserted into a holding frame, it is necessary for the modules to be held on the holding frame in order to enable the holding frame to be attached, for example, to a connector together with the modules. With one from the DE 10 2012 110 907 A1 known holding frame, it is provided for this purpose that a second holding frame part can be attached to a first holding frame part, which has recesses for receiving protruding elements of modules, in order to act on them Way to lock protruding elements lying in the recesses and thus to lock them on the holding frame.

With one from the DE 20 2012 103 360 U1 known holding frames are provided on frame walls of two types of recesses. Projecting elements of modules can be pushed into first recesses on an upper edge of the frame walls, while pin-like projections of the modules can be brought into engagement with second recesses in the form of openings.

The DE 10 2013 113 975 B4 describes how in Fig. 13 is shown, a holding frame 100 for a connector with at least one cheek part 16, which has a rectangular basic shape. The cheek part 16 thus has two opposing long edges here, namely a first and a second edge, and at right angles thereto two opposing short edges, namely a third and a fourth edge. On the base frame 10, two cheek parts 16 are arranged opposite one another, the modules 200 being held in the base frame 10 via the cheek parts 16. The cheek parts 16 are flat over their entire extent, so that the cheek parts 16 each extend in only one plane.

The object of the present invention is to provide a holding frame, a connector and an electronic device in which the fastening of a module in a holding frame can be further improved.

The object is achieved according to the invention with the features of the independent claims. Appropriate refinements and advantageous developments of the invention are specified in the subclaims.

The holding frame according to the invention is characterized in that the at least one cheek part has a trapezoidal taper.

Due to the trapezoidal tapering, the cheek part, also called the wall segment, is now no longer rectangular. As a result of the taper, two opposite outer edges of the cheek part are not arranged parallel to one another, but rather these two outer edges are set at an angle to one another. In the direction of the taper, these two outer edges run towards one another. Through the Tapering, the cheek part has a width that changes over the length of the cheek part, so that the cheek part no longer has a constant width, as is the case with a rectangular cheek part. This tapering enables a uniformly distributed bending stress over the length of the cheek part and thus a uniform deformation of the cheek part over the bending length of the cheek part when inserting and removing the modules from an interior of the base frame. In addition, a greater elastic deflection can take place without plastic deformation than if a rectangular cheek part, which has a constant width, is used. As a result of the tapering, a uniform tension profile can be achieved over the length of the cheek part if the cheek part springs when the respective module is inserted and removed. The trapezoidal taper causes a reduction in the spring stiffness of the cheek part formed from a resilient sheet metal. With the same deflection, a pressing force can thereby be reduced, which in turn can reduce the insertion force required for inserting the modules into the holding frame. As a result of the tapering, material can also be saved on the cheek part, the material saving being made in the areas which are preferably not necessary for the function of the cheek part, namely holding the modules on the base frame.

The at least one cheek part preferably has a fastening area for holding the modules, the at least one cheek part preferably tapering in a trapezoidal shape in the direction of the fastening area. The cheek part thus preferably has the smallest width immediately adjacent to the fastening area. In this way, directly adjacent to the fastening area or in the fastening area, the cheek part can perform a greater deflection when the modules are inserted, which at the same time enables an improved rear locking and thus locking of the fastening area on the module to be achieved. In the direction of the fastening area, the taper can increase the elasticity of the cheek part, as a result of which a type of flexible joint can be formed on the cheek part. The cheek part is designed to be resilient and, for this purpose, can be made from a spring plate, for example. When inserting a module, the cheek part mounted on the base frame can spring outward at its fastening area and thus away from an interior of the base frame in order to enable the module to be introduced into the interior. If the module is positioned in the desired position in the interior of the base frame, the fastening area of the cheek part can return again Spring or pivot in the direction of the interior of the base frame so that the fastening area of the cheek part can hold the module in this position.

The fastening area is preferably formed on a head area of the at least one cheek part, which is positioned on an end section of the cheek part opposite a foot area. The fastening area and the foot area of a cheek part thus preferably have the greatest possible distance from one another.

The at least one cheek part can have a middle section between the foot area and the head area, wherein the middle section can taper trapezoidally starting from the foot area towards the head area and can be reversibly deformable. This trapezoidal taper allows a uniform deformation of the cheek part, particularly in the area of the central section of the cheek part, over the bending length of the cheek part when inserting and removing a module from the interior of the base frame. The deformation is reversible, which means that an elastic and precisely no plastic deformation of the central section can take place. The central section forms a deformation section of the cheek part due to the trapezoidal taper. In the area of its deformation section, the cheek part thus has the trapezoidal taper. A deformation of the cheek part takes place preferably exclusively in the middle section and not in the head area or fastening area and also not in the foot area of the cheek part. As a result of the tapering, starting from the foot region towards the fastening region or the head region, the bending stress of the cheek part can decrease from the foot region towards the fastening region. The foot area can form a clamping location of the cheek part on the base frame, in particular on a receiving section of the base frame. By reducing the width of the cheek part by the trapezoidal tapering starting from this clamping point, the foot area of the cheek part, a uniform tension curve over the length of the cheek part can be achieved if the cheek part springs when inserting and removing the respective module. In the direction of the head region, the tapering can increase the elasticity of the cheek part, whereby a type of flexible joint can be formed on the cheek part. Viewed along the length of the cheek part, the middle section preferably has a significantly larger area than the foot area and the fastening area of the cheek part. In contrast to the middle section, the foot area can and / or the head area have a constant width, so that it can be provided that the trapezoidal taper is formed exclusively in the central section. The trapezoidal taper is preferably formed over the entire length of the central section.

The two opposite outer edges of the cheek part, which are not arranged parallel to one another, but rather are designed to run towards one another in order to form the trapezoidal taper, can be linear. However, it is also possible for these outer edges of the cheek part, which extend along the central section, to have a curve shape. Due to the curved shape of the outer edges, the distribution of the bending stress within the cheek part can be further improved, so that the load acting on the cheek part when inserting and removing the modules can be reduced and at the same time an optimized spring effect of the cheek part can be achieved.

To hold the modules, the fastening area can have at least one fastening tab. The fastening tab can be designed such that in the mounted position the fastening tab can rest on an upper side of a projection element of the respective module, so that the fastening tab can prevent the inserted module from moving in the direction of insertion of the module into the base frame against the insertion direction of the module. The at least one fastening tab is preferably designed in such a way that it protrudes from a main plane of extent of the cheek part.

In order to be able to achieve greater stability when holding the modules in their position inserted into the base frame, the fastening area of the cheek part can have two fastening tabs, so that two fastening tabs can rest on an upper side of a projection element of the respective module at the same time. The two fastening tabs of a fastening area of a cheek part can be designed symmetrically to one another. The two fastening tabs can, however, also be designed asymmetrically to one another.

The two fastening tabs of a fastening area of a cheek part can be arranged on opposite outer edges of the cheek part. The two outer edges preferably delimit the respective cheek part towards the outside. Through the Arrangement on the outer edges, the fastening tabs can be arranged in the form of two wings on the cheek part.

The fastening tabs are preferably designed to be curved in the area of the connection to the respective outer edge. The fastening tabs are preferably bent out of the main plane of extent of the cheek part. The fastening tabs can preferably each be designed to be bent at an angle α ≥ 90 ° to the outer edge of the cheek part. Particularly preferably, the fastening tabs can each be designed to be bent at an angle α zu 180 ° to the outer edge of the cheek part.

The at least one fastening tab preferably has a length which is at least three times the thickness of the cheek part. The thickness of the cheek part means the sheet metal thickness of the cheek part when it is formed from a spring plate. It has been shown that with a length of the respective fastening tab of at least three times the thickness of the cheek part, particularly good holding properties can be achieved with the fastening tabs for holding the modules in the base frame. The length of the fastening tab is in the main direction of extent of the fastening tabs.

The at least one cheek part can be arranged in a mounted position on a receiving section formed on a side wall of the base frame, wherein the receiving section can have an opening for receiving a projection element of a module inserted into an interior of the base frame, the opening in the mounted position of the cheek part can be at least partially overlapped on the base frame by the fastening area of the cheek part. The cheek part and preferably several such cheek parts can be arranged on the base frame. For example, each module inserted or introduced into the base frame can be held or fastened to the base frame via two oppositely arranged cheek parts. The mounted position is the position in which the string part is arranged on the base frame and a module inserted into the interior of the base frame can be held by the string part. A plurality of receiving sections are preferably each formed on two opposite side walls of the base frame on which the cheek parts can be arranged. The receiving portions of a side wall are preferred side by side and thus arranged in a row. The receiving sections are preferably at least partially formed into the respective side wall of the base frame, so that the receiving sections can form a defined receiving area for the cheek parts. Each cheek part to be arranged on the base frame is preferably assigned a receiving section, so that a cheek part can be arranged on each receiving section. Each receiving section preferably has an opening which, in the mounted position of the cheek parts on the base frame, is at least partially overlapped by the fastening area of the cheek part assigned to the receiving section. The openings are preferably designed in the form of openings on the base frame or on the side walls of the base frame. The openings preferably extend from the upper edge of the base frame into the base frame. Via the openings, the cheek parts can be brought into operative connection with the modules, in particular with the protruding elements of the modules, in order to be able to hold the modules in the interior of the base frame. For this purpose, the protruding elements of the modules can protrude into the respective opening. In the mounted position, the openings can be covered at least in some areas by the fastening area of the respective cheek part, so that the fastening area of the cheek parts can each cover or overlap a projection element of an inserted module at the end.

In order to be able to form a coding for the insertion of the modules in the correct position, the openings of the receiving sections formed on the first side wall can have a greater width than the openings of the receiving sections formed on the second side wall. The two projection elements formed on a module also preferably have a different width, so that the module can only be inserted in such a way that the wider projection element is inserted into the wider opening of a receiving section and the narrower projection element of a module is inserted into the narrower opening of a receiving section can. Incorrect insertion of the modules into the base frame and thus into the holding frame can thus be avoided.

The receiving sections are preferably each formed on an outer side of the base frame facing away from the interior space. In the assembled position, the cheek parts therefore preferably rest on the outside of the base frame. Preferably, no part or region of a cheek part is arranged in the mounted position on an inside of the base frame pointing in the direction of the interior of the base frame. The cheek parts therefore no longer have to be curved in a costly manner, since it is no longer necessary to grip around the lower edge of the base frame in the case of the cheek parts according to the invention.

The at least one cheek part is preferably fastened or held via its foot region to the receiving section assigned to it and thus to the base frame. The cheek part is therefore preferably not attached to the base frame via its head area or its attachment area. In contrast to the foot area, the head area or the fastening area is preferably exposed with respect to the base frame, so that there is preferably no contact between the head area or the fastening area of the cheek part with the base frame in the mounted position.

The attachment of the foot area of a cheek part to the receiving section or to the base frame can be done in various ways. For example, the attachment can be formed by means of a latching connection and / or a rivet connection and / or an adhesive connection between the cheek part and the base frame.

The at least one cheek part can have a fastening element on its foot region which, in the assembled position, can engage with an opening formed on the base frame. Each receiving section can have such an opening. The fastening element can be designed, for example, in the form of a tab or a nose which, in the assembled position, can dip into an opening on the base frame or on the respective receiving section and snap behind or hook behind there.

A fastening of a cheek part to the base frame can preferably be designed in such a way that the base frame has at least one slot-shaped recess into which the foot area of the at least one cheek part can be inserted in the assembled position. Each cheek part can thereby be arranged and fastened individually on the base frame and thus individually on its respectively assigned receiving section. With such a fastening, however, the cheek parts can also be attached to the base frame in pairs and thus two or more cheek parts can be attached simultaneously to their respectively assigned receiving section are arranged and fastened. By inserting the cheek parts, at least with their foot area, into a slot-shaped recess of the receiving section assigned to them, the cheek parts can be mounted on the base frame particularly easily and quickly. The structural design of the holding frame can also be designed in a significantly simplified manner as a result. The slot-shaped recesses can each form a pocket on the base frame, into which the cheek parts can engage at least in some areas, here with their foot area, in the assembled position. The foot area of the cheek parts, with which the cheek parts can be pushed into the slot-shaped recess, is preferably formed on an end section of the cheek parts.

The at least one slot-shaped recess is preferably formed on a lower edge of the base frame. The cheek parts can thus preferably each be attached to the base frame from below and pushed into the slot-shaped recesses. The mounting direction of the cheek parts on the base frame is thus preferably opposite to the direction of insertion of the modules into the interior of the base frame, so that the cheek parts can be pushed into the respective slot-shaped recess in a direction opposite to the insertion of the modules into the base frame. The modules are preferably introduced into the interior of the base frame from above.

The slot-shaped recesses of the receiving sections formed on the first side wall can be connected to one another and / or the slot-shaped recesses of the receiving sections formed on the second side wall can be connected to one another. The slot-shaped recesses formed on a side wall are preferably arranged one behind the other in a row. If the slot-shaped recesses formed on a side wall are connected to one another, the slot-shaped recesses can be configured in the form of a recess which can span all of the receiving sections of a side wall. Such a slot-shaped recess can extend over more than 2/3 of the length of the side wall.

In order to be able to achieve a separation of the function between the foot area and the middle section, an offset can be formed in a connection area of the foot area on the middle section in such a way that the foot area is in a first Plane and the central portion can extend in a second plane arranged offset from the first plane. As a result, the foot area can be arranged in the mounted position within the base frame in the slot-shaped recess, wherein the cheek part can be led out of the recess in the mounted position on the connecting area of the cheek part having the offset, so that the middle section and also the fastening area or the head area of the cheek part can be guided along the outside of the base frame and so that it no longer engages in the slot-shaped recess of the receiving section. Due to the offset along the length of the cheek part, the cheek part is no longer flat over its entire length.

The receiving sections can each have a contact surface on which an inner surface of the cheek parts pointing in the direction of the interior of the base frame can rest in the mounted position. By resting the cheek parts on the respective receiving section via their middle section, good and positionally secure support of the cheek parts on the receiving sections and thus on the base frame can be achieved. The contact surface preferably points away from the interior of the base frame.

A particularly secure positioning of the cheek parts on the base frame can also be achieved in that the contact surface of a receiving section can be delimited by two opposing inner edges, with the outer edges of the cheek parts in the mounted position in the area of the central section of the cheek parts in a form-fitting manner on the inner edges of them assigned receiving section can rest. A lateral displacement of the cheek parts, in particular when inserting and removing the modules, can be reliably prevented because the cheek parts are supported on both sides by the outer edges and their movement is limited.

It is also possible that a marking element can be attached to each of the cheek parts. The identification element can already be labeled or it can be labeled individually by the user. The identification elements can offer the possibility of identifying the modules or the slots for the modules in the interior of the base frame. The marking element can particularly preferably be fastened or fastened to the foot region of the cheek part become. The identification element can for example be inserted into the slot-shaped recess together with the foot area in order to fasten the identification element. It can furthermore also be the case that the marking element is glued onto the cheek part. By means of the identification element, the slots for the modules can be individually identified without increasing the space required for the holding frame.

The cheek parts can be designed as individual elements, or two or more cheek parts arranged on a side wall can be connected to one another. The cheek parts connected to one another are then preferably formed integrally with one another.

The cheek parts are particularly preferably connected to one another in one piece at their foot area. If two or more wall segments are connected to one another, the fastening of the cheek parts to the base frame can take place even more quickly.

The object according to the invention is also achieved by means of a plug connector which has a housing, a holding frame arranged in the housing and at least one module accommodated in the holding frame, the holding frame being designed and developed as described above.

The object according to the invention is also achieved by means of an electronic device which has at least one previously described, developed and further developed connector.

The invention is explained in more detail below with reference to the attached drawings on the basis of preferred embodiments.

Fig. 13

a schematic representation of a holding frame according to the prior art.

Figures 2 to 7 each show a schematic representation of a holding frame 100 which can be arranged in a housing of a connector.

The holding frame 100 has a base frame 10 which is formed in one piece. The base frame 10 has a first side wall 11, a second side wall 12 opposite the first side wall 11, a first end wall 13 and a second end wall 14 opposite the first end wall 13. The two side walls 11, 12 are arranged parallel to one another. The two end walls 13, 14 are also arranged parallel to one another. The end walls 13, 14 are arranged at a 90 ° angle to the side walls 11, 12. The two side walls 11, 12 and the two end walls 13, 14 together enclose or delimit an interior space 15 of the base frame 10. In this interior space 15, modules 200 can be inserted in the direction of insertion E, as shown, for example, in FIG Fig. 6 is shown, inserted and secured.

The modules 200 are fastened by means of cheek parts 16 arranged on the base frame 10, as they are in particular in FIG Figures 1a and 1b are shown. The cheek parts 16 arranged on a base frame 10 are each designed in the same way. In the base frame 10 shown here, four such cheek parts 16 are arranged, two cheek parts 16 being arranged on the first side wall 11 and two cheek parts 16 on the second side wall 12.

The base frame 10 is made from a different material than the cheek parts 16. The base frame 10 is made from a material which has a lower elasticity and thus greater rigidity than the cheek parts 16.

The base frame 10 is rigid. The base frame 10 is designed as a die-cast part.

The cheek parts 16 are each designed to be resilient. The cheek parts 16 can be formed from a spring plate.

Fig. 1a shows a plan view of an outer surface 17 of a cheek part 16, which is directed away from the interior 15 of the base frame 10 in the position mounted on the base frame 10.

Figure 1b shows a plan view of an inner surface 18 of the cheek part 16 which, in the position mounted on the base frame 10, points in the direction of the interior 15 of the base frame 10.

The cheek parts 16 each have a foot region 19, a head region 20 and a central section 21 arranged between the foot region 19 and the head region 20. Along the length of the cheek part 16, viewed from the foot area 19 to the head area 20, the middle section 21 has a significantly larger area than the head area 20 and the foot area 19. The foot area 19 is formed at a first end section of the cheek part 16 and the head area 20 is formed on a second end section of the cheek part 16 opposite the first end section.

At the foot region 19, the cheek part 16 has the greatest width B _F. The cheek part 16 has the smallest width B _K at the head region 20. In the area of the middle section 21, the cheek part 16 tapers in a trapezoidal shape, in that the width B _{M of} the middle section 21 tapers starting from the foot area 19 towards the head area 20. By tapering the width B _{M of} the middle section 21 starting from the foot region 19 towards the head region 20, a uniform deformation of the cheek part 16 over the length of the cheek part 16 when inserting and removing the modules 200 can be achieved.

In the area of the middle section 21, the outer edges 22, 23 of the cheek part 16 in the one shown here are not straight, but rather have a curve shape along the length of the middle section 21 and thus starting from the foot area 19 to the head area 20. The two outer edges 22, 23 of the cheek part 16 can, however, also be designed in a straight line. The outer edges 22, 23 do not run parallel to one another, but they are arranged so as to be adjusted to one another. Starting from the foot region 19, the outer edges 22, 23 converge in the direction of the head region 20, so that the cheek part 16 tapers in a trapezoidal shape in the region of its central section 21, starting from the foot region 19 towards the head region 20.

In the connection area 24 of the foot area 19 to the middle section 21, an offset is formed such that the foot area 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 oriented essentially parallel to one another.

The foot region 19 has two laterally formed shoulder surfaces 25, 26, both of which, in the mounted position of the cheek part 16 on the base frame, can engage in a slot-shaped recess 27 formed on the base frame 10 of a receiving section 35, as shown, for example, in FIG Fig. 5 can be seen. The two shoulder surfaces 25, 26 protrude laterally outward in such a way that they laterally overlap or protrude beyond the central section 21 and the head region 20.

The foot region 19 also has a fastening element 28 which can engage in an opening 29 formed on the base frame 10. The fastening element 28 is designed here in the form of a tab that has been sheared out of the foot region 19 and is designed to be curved in the direction of the base frame 10. The fastening element 28 in the form of the tab can hook into the opening 29. The fastening element 28 is formed in the middle of the width B _{F of} the foot region 19.

A fastening area 30 is formed on the head area 20, via which a module 200 introduced into the interior space 15 can be held in the interior space 15. The fastening area 30 has two fastening tabs 31, 32. In the mounted position of the cheek part 16 on the base frame 10, the fastening tabs 31, 32 extend in the direction of the interior 15 of the base frame 10. The two fastening tabs 31, 32 are each molded onto one of the two outer edges 22, 23 of the cheek part 16. At the in Figures 1a, 1b In the embodiments shown, the fastening tabs 31, 32 are each bent at an angle α of approximately 90 ° to the outer edge 22, 23 of the cheek part 16. The fastening tabs 31, 32 thus protrude from the main plane of extent of the cheek parts 16.

The lower edges 33 of the fastening tabs 31, 32, with which the fastening tabs 31, 32 rest on the projection elements 210 of the modules 200 in order to be able to hold the modules 200 in the interior 15 of the base frame 10, are essentially straight. The upper edges 34 of the fastening tabs 31, 32 opposite the lower edges 33 are, however, formed at an angle so that the upper edges 34 have a Can form an insertion bevel in the direction of the insertion direction E of the modules 200 into the interior 15 of the base frame 10. As a result of the insertion bevel, the modules 200, in particular the projection elements 210 of the modules 200, can slide along the upper edge 34 of the two fastening tabs 31, 32 when they are inserted and thereby bend the cheek parts 16 outward so that the cheek parts 16 spring outward and the interior space 15 of the base frame 10, so that the modules 200 with their protruding elements 210 can be introduced into the interior 15 of the base frame 10. Once the modules 200 have been inserted into the interior 15, the cheek parts 16 can spring back again automatically until they rest with their lower edge 33 on the projection elements 210 in order to hold the modules 200 in the interior 15 of the base frame 10. The length of the individual fastening tabs 31, 32 is preferably at least three times the thickness or the sheet metal thickness of the cheek part 16, whereby particularly good holding properties can be achieved for the fastening tabs 31, 32 for holding the modules 200 in the base frame 10.

As in Fig. 2 As can be seen, the base frame 10 has a receiving section 35 for each cheek part 16. The receiving sections 35 are formed on an outer side 36 of the base frame 10 facing away from the interior 15. The receiving sections 35 are formed on the two side walls 11 and 12 of the base frame 10. In the embodiment shown here, two receiving sections 35 are formed both on the first side wall 11 and on the second side wall 12.

Each receiving section 35 has a slot-shaped recess 27 into which the foot region 19 of the respective cheek part 16 with its two shoulder surfaces 25, 26 can be inserted. The slot-shaped recesses 27 of the receiving sections 35 of the first side wall 11 and the slot-shaped recesses 27 of the receiving sections 35 of the second side wall 12 are each connected to one another in the embodiment shown here, as in FIG Fig. 5 can be seen, so that the recesses 27 of the receiving sections 35 of a side wall 11, 12 together form a recess 27 per side wall 11, 12. The respective recess 27 extends over almost the entire length of the respective side wall 11, 12.

The recesses 27 of the receiving sections 35 are formed on a lower edge 37 of the base frame 10. The cheek parts 16 can therefore be fastened to the base frame 10 from below along an assembly direction M. The cheek parts 16 can so that the modules 200 are fastened into the interior 15 of the base frame 10 on the base frame 10 counter to the insertion direction E.

Above their slot-shaped recess 27, the receiving sections 35 each have a contact surface 38. The contact surfaces 38 are each formed on the outside 36 of the base frame 10, in that the contact surfaces 38 each form a type of recess on the outside 36 of the base frame 10. In the mounted position, the respective wall section 16 rests flat against the contact surface 38 with its central section 21. The contact surfaces 38 are each delimited by two opposing inner edges 41, 42, the outer edges 22, 23 of the respective cheek part 16 resting positively on the inner edges 41, 42 in the assembled position. The inner edges 41, 42, like the outer edges 22, 23, thus have a curve shape. The inner edges 41, 42 are preferably designed so high that, in the assembled state, the cheek parts 16 are flush with the outer side 36 of the base frame 10. Due to the inner edges 41, 42, the contact surface 38 of the receiving sections 35 is arranged offset in the direction of the interior 15 of the base frame 10 relative to the outside 36 of the base frame 10.

Above the contact surface 38, the receiving sections 35 each have an opening 39 which, starting from an upper edge 40 of the base frame 10, extend into the respective side wall 11, 12 of the base frame 10. In the assembled position of the cheek parts 16, the fastening area 30 or the head area 20 of the respective cheek part 16 overlap the opening 39 at least in some areas. The fastening tabs 31, 32 can protrude into the opening 39. In the region of the opening 39, the fastening tabs 31, 32 can hold the modules 200 in place by the fastening tabs 31, 32 resting on the projection elements 210 of the modules 200 which protrude into the opening 39, as in particular in FIG Fig. 6 can be seen.

As in particular in Fig. 2 and Fig. 7 As can be seen, the openings 39 on the first side wall 11 have a greater width than the openings 39 on the second side wall 12.

Fig. 3 shows the assembly of one of the cheek parts 16 on the base frame 10 in that the cheek part 16 is pushed in the assembly direction M into the slot-shaped recess 27, in particular the two shoulder surfaces 25, 26 of the foot region 19 in the slot-shaped recess 27 are introduced and thus engage in the slot-shaped recess 27. With its middle section 21, the cheek part 16 slides along the contact surface 38. The cheek parts 16 are pushed in until the fastening element 28 of the foot region 19 hooks into the opening 29 on the base frame 10, as in FIG Fig. 4 can be seen. In this assembled position, the head region 20 or the fastening region 30 of the cheek part 16 is located in the region of the opening 39 in order to overlap it at least in regions.

If the cheek parts 16 are mounted on the base frame 10, the modules 200 can be inserted in the insertion direction E into the interior 15 of the base frame 10. The modules 200 slide with their protruding elements 210 along the upper edges 34 of the fastening tabs 31, 32, as a result of which they and thus the fastening area 30 of the respective cheek part 16 spring outwards in order to let the protruding elements 210 past the fastening tabs 31, 32. If the modules 200 are guided past the fastening straps 31, 32, they can spring back again in the direction of the interior 15 until they rest on the projection element 210 on top, as in FIG Fig. 6 and 7th can be seen. In this position, the protruding elements 210 are each covered on the front side by the cheek part 16 assigned to them, in particular by the central section 21 of the cheek part 16, as for example in FIG Fig. 6 and 7th can be seen.

Fig. 8 and 9 show a configuration similar to that in FIG Fig. 1a , 1b and 2 to 7 embodiment shown, wherein here only the shape of the fastening tabs 31, 32 is designed differently, since here the fastening tabs 31, 32 are bent at an angle α ≥ 180 ° to the outer edges 22, 23 of the cheek part 16. The fastening tabs 31, 32 of a cheek part 16 are in the in Fig. 8 and 9 embodiment shown bent towards each other.

Fig. 10 further shows the arrangement of a marking element 43 in the region of the cheek part 16. The marking element 43 is arranged on the foot region 19 on the cheek part 16. The marking element 43 is here attached to the foot region 19 of the cheek part 16 by an adhesive connection.

In Figures 11 and 12 an embodiment is shown in which the two cheek parts 16 arranged on a side wall 12 are connected to one another in one piece. The two cheek parts 16 are formed integrally with one another at their foot region 19. The Cheek parts 16 are connected to one another in one piece via the shoulder surfaces 25, 26 of the foot regions 19.

The recess 26 extends here over the two receiving sections 35 of the side wall 12 and thus over almost the entire length of the side wall 12. The one-piece cheek parts 16 can thus be pushed into the recess 26 via their one-piece foot regions 19 and thus on the base frame 10 or be mounted on the side wall 12 of the base frame 10.
