Description

The invention relates to a holding frame for a connector for installation in a metal connector housing and for protective earthing of the same, and for accommodating identical and/or different modules, the holding frame being made of at least two different materials, at least one of which is electrically conductive, with 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 consisting of resilient sheet metal. Furthermore, the invention 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 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 via the holding frame in or on a connector part.

Such modules can have one or more electrical contacts, for example. In this case, the modules are on the one hand connected 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 brought into engagement with a mating connector part for electrical contacting.

Such modular modules offer the advantage of being able to be combined flexibly and thus allowing connectors to be used in a variety of ways.

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 to a connector together with the modules, for example. At 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 projection elements of modules, in order to onto this Way to lock inset projection elements in the recesses and thus to lock them on the holding frame.

At one from the DE 20 2012 103 360 U1 known holding frame two types of recesses are provided on frame walls. In first recesses on an upper edge of the frame walls, projection elements of modules can be inserted in an engaging manner, while pin-like projections of the modules can be brought into locking engagement with second recesses in the form of openings.

The DE 10 2013 113 975 B4 describes as in 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 opposite long edges, namely a first and a second edge, and at right angles thereto two opposite short edges, namely a third and a fourth edge. Two cheek parts 16 are arranged opposite one another on the base frame 10 , 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 plug 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. Expedient configurations and advantageous developments of the invention are specified in the dependent claims.

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 taper, the cheek part, also called wall segment, is no longer rectangular. Due to the tapering, two opposite outer edges of the cheek part are not arranged parallel to one another, but these two outer edges are set at an angle to one another. In the direction of the taper, these two outer edges converge. 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. Due to this tapering, 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 can be achieved when inserting and removing the modules from an interior space of the base frame. In addition, a larger elastic deflection can take place without plastic deformation than when a rectangular cheek part having a constant width is used. Due to the tapering, a uniform stress profile over the length of the cheek part can be achieved if the cheek part springs when the respective module is inserted and removed. The trapezoidal tapering causes a reduction in the spring stiffness of the cheek part, which is made from a spring-elastic sheet metal. With the same deflection, a contact pressure force can be reduced, which in turn can reduce the plug-in force required to insert the modules into the holding frame. Due to the tapering, material can also be saved on the cheek part, with the material being saved in the areas which are preferably just not necessary for the function of the cheek part, namely holding the modules on the base frame.

According to the invention, the at least one cheek part has a fastening area for holding the modules, with the at least one cheek part preferably tapering in a trapezoidal manner 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, the cheek part can perform a greater deflection when inserting the modules directly adjacent to the fastening area or in the fastening area, whereby improved rear locking and thus locking of the fastening area on the module can be achieved at the same time. In the direction of the attachment area, the elasticity of the cheek part can be increased by the narrowing, 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 can be designed for this purpose, for example, from a spring steel sheet. When a module is inserted, the cheek part mounted on the base frame can spring outwards at its fastening area and thus away from an interior space of the base frame in order to enable the module to be inserted into the interior space. If the module is positioned in the desired position in the interior of the base frame, the fastening area of the cheek part can go back again bounce 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.

According to the invention, the fastening area is 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 are therefore preferably at the greatest possible distance from one another.

According to the invention, the at least one cheek part has a middle section between the foot area and the head area, the middle section tapering in a trapezoidal manner starting from the foot area towards the head area and being reversibly deformable.

This trapezoidal taper allows a uniform deformation of the cheek part, particularly in the area of the middle 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 rather than a plastic deformation of the middle section can take place. Due to the trapezoidal taper, the middle section forms a deformation section of the cheek part. In the area of its deformation section, the cheek part thus has the trapezoidal taper. A deformation of the cheek part preferably takes place 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. Due to the tapering, starting from the foot area towards the fastening area or the head area, the bending stress of the cheek part can decrease from the foot area towards the fastening area. The foot area can form a clamping location for 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 due to the trapezoidal taper starting from this clamping location, the foot area of the cheek part, a uniform stress profile 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 area, the elasticity of the cheek part can be increased by the narrowing, as a result of which a type of flexible joint can be formed on the cheek part. The center portion preferably has a substantially larger area as viewed along the length of the cheek portion than the foot portion and attachment portion of the cheek part. In contrast to the middle section, the foot area and/or the head region have a constant width, so that it can be provided that the trapezoidal taper is formed exclusively in the middle section. The trapezoidal taper is preferably formed over the entire length of the middle section.

The two opposite outer edges of the cheek part, which are not arranged parallel to one another but are designed to run towards one another in order to form the trapezoidal taper, can be designed in a straight line. However, it is also possible for these outer edges of the cheek part, which extend along the central section, to have a curved 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 strap. The fastening strap can be designed in such a way that in the mounted position the fastening strap can rest on an upper side of a projection element of the respective module, so that the fastening strap can prevent movement of the inserted module counter to the insertion direction of the module in the insertion direction of the module into the base frame. The at least one fastening strap is preferably designed in such a way that it protrudes from a main extension plane of the cheek part.

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

The two fastening straps of a fastening region of a cheek part can be arranged on opposite outer edges of the cheek part. The two outer edges preferably limit the respective cheek part to 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 curved in the area of the connection to the respective outer edge. The fastening tabs are preferably bent out of the main extension plane of the cheek part. Preferably, the fastening tabs can each be bent at an angle α≧90° to the outer edge of the cheek part. Particularly preferably, the fastening tabs can each be bent at an angle α≧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 if it is made from a spring steel sheet. It has been shown that with a length of the respective fastening strap of at least three times the thickness of the cheek part, particularly good holding properties can be achieved with the fastening straps for holding the modules in the base frame. The length of the fastening strap is in the main direction of extension of the fastening straps.

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 space of the base frame, the opening being 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 piece. 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 cheek parts arranged opposite one another. The mounted position is the position in which the cheek part is arranged on the base frame and a module inserted into the interior space of the base frame can be held by the cheek part. A plurality of receiving sections are preferably 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 arranged next to each other and thus in a row. The receiving sections are preferably formed at least in regions into the respective side wall of the base frame, so that the receiving sections can form a defined receiving area for the cheek parts. A receiving section is preferably assigned to each cheek part to be arranged on the base frame, so that a cheek part can be arranged on each receiving section. Each receiving section preferably has an opening, which in the installed 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 in the form of openings on the base frame or on the side walls of the base frame. The openings preferably extend into the base frame starting from the upper edge of the base frame. The cheek parts can be brought into operative connection with the modules, in particular with the projection elements of the modules, via the openings in order to be able to hold the modules in the interior of the base frame. For this purpose, the projection elements of the modules can protrude into the respective opening. In the installed position, the openings can be at least partially covered by the attachment area of the respective cheek piece, so that the cheek pieces can each cover or engage over a projection element of an inserted module at the end with their attachment area.

In order to be able to form a code for inserting 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. This can prevent the modules from being incorrectly plugged into the base frame and thus into the holding frame.

The receiving sections are preferably each formed on an outside of the base frame facing away from the interior. In the assembled position, the cheek parts are preferably in contact with the outside of the base frame. Preferably, no part or area 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 no longer have to be curved in a complex manner, since gripping around the lower edge of the base frame is no longer necessary with the cheek parts according to the invention.

The at least one cheek part is preferably fastened or held via its foot area on the receiving section assigned to it and thus on the base frame. The cheek piece 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 attachment area is preferably exposed relative to the base frame, so that there is preferably no contact between the head area or the attachment area of the cheek part and the base frame in the assembled position.

The foot area of a cheek piece can be attached to the receiving section or to the base frame in various ways. For example, the attachment can be formed by means of a latching connection and/or a riveted 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 in its foot area, which in the mounted position can engage in 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 lug which, in the mounted position, dips into an opening on the base frame or on the respective receiving section and can latch or hook behind there.

A cheek piece can preferably be fastened to the base frame in such a way that the basic frame has at least one slot-shaped recess into which the foot area of the at least one cheek piece can be inserted in the installed position. As a result, each cheek part can be arranged and fastened individually on the base frame and thus individually on its respective associated receiving section. With such an attachment, the cheek pieces can also be attached in pairs to the base frame and thus two or more cheek pieces to their at the same time each associated receiving section are arranged and fixed. By inserting the cheek parts, at least with their foot region, 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 made much simpler 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 certain areas, here with their foot area, in the mounted 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 fastened 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 therefore 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 inserted 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 slit-shaped recesses formed on a side wall are connected to one another, the slit-shaped recesses can be formed in the form of a recess which can span all 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 separate the function between the foot area and the middle section, according to the invention an offset is formed in a connection area of the foot area to the middle section in such a way that the foot area is in a first Level and the central portion extends in a offset to the first level arranged second level.

The foot area can thus be arranged in the installed position within the base frame in the slot-shaped recess, whereby the cheek part can be guided out of the recess in the installed position at the connection area of the cheek part that has 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 against which an inner surface of the cheek parts pointing in the direction of the interior of the base frame can rest in the assembled position. By the cheek parts resting on their central section on the respective receiving section, a 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 position 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 opposite inner edges, with the outer edges of the cheek parts in the area of the middle section of the cheek parts being in a form-fitting manner on the inner edges of them associated recording section may be present. Lateral displacement of the cheek parts, in particular when inserting and removing the modules, can be reliably prevented in this way, since the cheek parts are supported on both sides by the outer edges and their movement is limited.

It is also possible for a marking element to be fastened to each of the cheek parts. The identification element can already be labeled or it can be individually labeled 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. Particularly preferably, the identification element can be attached or attached to the foot area of the cheek part become. The identification element can be inserted into the slot-shaped recess together with the foot area, for example, in order to fasten the identification element. Furthermore, it can also be the case that the identification element is glued onto the cheek piece. Using the identification element, an individual identification of the slots for the modules is possible without increasing the space required for the holding frame.

The cheek parts can be formed 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 in one piece 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 cheek parts can be fastened to the base frame 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 plug connector which has been developed and developed as described above.

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

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 designed 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. Modules 200 can be inserted into this interior space 15 in the insertion direction E, as is the case, for example, in 6 shown, inserted and secured.

The attachment of the modules 200 is arranged on the base frame 10 cheek parts 16, as in particular in the Figures 1a and 1b are shown. The cheek parts 16 arranged on a base frame 10 are each of the same design. Four such cheek parts 16 are arranged in the base frame 10 shown here, two cheek parts 16 being arranged on the first side wall 11 and two cheek parts 16 being arranged on the second side wall 12 .

The base frame 10 is made of a different material than the cheek parts 16. The base frame 10 is made of a material which has less elasticity and therefore 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 steel sheet.

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 mounted position on the base frame 10. FIG.

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

The cheek parts 16 each have a foot area 19 , a head area 20 and a middle section 21 arranged between the foot area 19 and the head area 20 . Viewed along the length of the cheek piece 16 from the foot area 19 to the head area 20, the middle section 21 has a substantially 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 piece 16 and the head area 20 is formed at a second end portion of the cheek portion 16 opposite the first end portion.

The cheek part 16 has the greatest width B _F in the foot area 19 . The cheek part 16 has the smallest width B _K in the head region 20 . In the area of the central section 21, the cheek part 16 tapers in a trapezoidal manner, in that the width B _M of the central section 21 tapers, starting from the foot area 19 towards the head area 20. Due to the tapering of the width B _M of the middle section 21 starting from the foot area 19 towards the head area 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 are not straight in the case shown here, but have a curved shape along the length of the middle section 21 and thus starting from the foot area 19 to the head area 20. However, the two outer edges 22, 23 of the cheek part 16 can also be formed in a straight line. The outer edges 22, 23 do not run parallel to one another, but rather they are arranged in relation to one another. Starting from the foot area 19, the outer edges 22, 23 converge in the direction of the head area 20, so that the cheek part 16 tapers in the area of its middle section 21, starting from the foot area 19 towards the head area 20 in a trapezoidal manner.

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 to the first plane. The first level and the second level are oriented substantially parallel to each other.

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

Furthermore, the foot area 19 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 clip that has sheared out of the foot area 19 and is 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 area 19 .

A fastening area 30 is formed on the head area 20 , via which a module 200 inserted into the inner space 15 can be held in the inner space 15 . The fastening area 30 has two fastening straps 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 space 15 of the base frame 10. The two fastening tabs 31, 32 are each formed on one of the two outer edges 22, 23 of the cheek part 16. At the in Figures 1a, 1b 90 ° to the outer edge 22, 23 of the cheek part 16 are each bent at an angle α of about 90 °. The fastening tabs 31, 32 thus protrude from the main extension plane 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 lower edges 33 opposite upper edges 34 of the fastening tabs 31, 32, however, are formed obliquely, so that the upper edges 34 a Can form insertion bevel in the direction of the insertion direction E of the modules 200 in the interior 15 of the base frame 10. Due to 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 straps 31, 32 during their insertion and thereby bend the cheek parts 16 outwards, so that the cheek parts 16 spring outwards and the interior Release 15 of the base frame 10, so that the modules 200 can be inserted with their projection elements 210 into the interior 15 of the base frame 10. If the modules 200 are inserted into the interior 15, the cheek parts 16 can spring back 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 lugs 31, 32 is preferably at least three times the thickness or sheet metal thickness of the cheek part 16, as a result of which particularly good holding properties can be achieved with the fastening lugs 31, 32 for holding the modules 200 in the base frame 10.

As in 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 pointing away from the interior space 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 area 19 of the respective cheek part 16 can be pushed with its two shoulder surfaces 25, 26. The slit-shaped recesses 27 of the receiving sections 35 of the first side wall 11 and the slit-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 figure 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 a mounting direction M. The cheek parts 16 can so that the modules 200 are fastened to the base frame 10 in the interior 15 of the base frame 10 counter to the insertion direction E.

The receiving sections 35 each have a contact surface 38 above their slot-shaped recess 27 . 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 lies 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, with the outer edges 22, 23 of the respective cheek part 16 being in positive contact with the inner edges 41, 42 in the mounted position. The inner edges 41, 42 thus have, like the outer edges 22, 23, a curved shape. The inner edges 41, 42 are preferably formed 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 offset in the direction of the interior 15 of the base frame 10 to the outside 36 of the base frame 10 is arranged.

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, extends into the respective side wall 11, 12 of the base frame 10. In the mounted position of the cheek parts 16, the fastening area 30 or the head area 20 of the respective cheek part 16 overlaps the opening 39 at least in certain areas. The fastening tabs 31, 32 can protrude into the opening 39. In the area 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 6 can be seen.

As in particular in 2 and 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.

3 shows the assembly of one of the cheek parts 16 on the base frame 10 by the cheek part 16 being pushed into the slot-shaped recess 27 in the assembly direction M, in particular the two shoulder surfaces 25, 26 of the foot area 19 in the slit-shaped recess 27 are introduced and thus engage in the slit-shaped recess 27. The cheek part 16 slides with its central section 21 along the contact surface 38. The cheek parts 16 are pushed in far enough for the fastening element 28 of the foot region 19 to hook into the opening 29 on the base frame 10, as shown in FIG 4 can be seen. In this mounted position, the head area 20 or the attachment area 30 of the cheek part 16 is located in the area of the opening 39 in order to overlap this at least in areas.

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 projection elements 210 along the upper edges 34 of the fastening straps 31, 32, as a result of which these and thus the fastening area 30 of the respective cheek part 16 spring outwards in order to let the projection elements 210 past the fastening straps 31, 32. If the modules 200 are guided past the fastening straps 31, 32, they can spring back in the direction of the interior 15 until they rest on the projection element 210 at the top, as in FIG 6 and 7 can be seen. In this position, the projection elements 210 are each covered at the end by the cheek part 16 assigned to them, in particular by the middle section 21 of the cheek part 16, as for example in 6 and 7 can be seen.

8 and 9 show a similar configuration to that in Figures 1a, 1b and 2 to 7 shown configuration, in which case only the shape of the fastening straps 31, 32 is designed differently, since here the fastening straps 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 8 and 9 shown configuration bent towards each other.

10 also shows the arrangement of an identification element 43 in the area of the cheek part 16. The identification element 43 is arranged in the foot area 19 on the cheek part 16. FIG. The identification element 43 is attached here to the foot area 19 of the cheek part 16 by means of an adhesive connection.

In 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 in one piece with each other at their foot area 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 integrally formed cheek parts 16 can thus be pushed into the recess 26 via their integrally formed foot regions 19 and thus on the base frame 10 or mounted on the side wall 12 of the base frame 10.
