Description

[0001] The invention relates to a retaining frame for a connector for receiving contact inserts, comprising a base frame which has a first side wall, a second side wall opposite the first side wall, a first end wall and a second end wall opposite the first end wall, wherein the first side wall, the second side wall, the first end wall and the second end wall enclose an interior of the base frame into which the contact inserts can be inserted along an insertion direction, and with several wall segments, each having a fastening area by means of which the contact inserts inserted into the interior of the base frame can be held on the base frame, wherein the several wall segments are arranged in a mounted position on a receiving section formed on the first side wall or on the second side wall.wherein the receiving sections each have an opening for receiving a protruding element of a contact insert inserted into the interior, wherein the openings in the mounted position are at least partially overlapped by the mounting area of ​​the wall segment associated with the receiving section. The invention further relates to a connector with such a retaining frame and an electronic device.

[0002] A corresponding retaining frame is known, for example, from DE 10 2015 114 814 A1. Further retaining frames are known, for example, from DE 10 2015 103 563 A1, DE 10 2013 113 975 B4, and DE 10 2016 211 300 A1. Such retaining frames serve for the modular use of contact inserts, for example, on connectors. One or more contact inserts can be arranged on such a retaining frame so that, together with the retaining frame, they can be inserted into the housing of a connector part or a connector and connected to the housing via the retaining 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 retaining frame.

[0003] Such contact inserts can, for example, have one or more electrical contacts. In this case, the contact inserts are connected on the one hand to electrical conductors that are fed into a connector and on the other hand form plug contacts via which the connector can be inserted to engage with a mating connector part for electrical contact.

[0004] Such modular contact inserts offer the advantage of flexible combinationability and thus variable usability of connectors.

[0005] If contact inserts are inserted into a retaining frame, it is necessary that the contact inserts be held in place by the retaining frame to allow the retaining frame, for example, to be attached to a connector together with the contact inserts. In a retaining frame known from DE 10 2012 110 907 A1, it is provided that a second retaining frame part can be attached to a first retaining frame part, which has recesses for receiving protruding elements of contact inserts, in order to lock the protruding elements located in the recesses and thus secure them to the retaining frame.

[0006] In a retaining frame known from DE 20 2012 103 360 U1, two types of recesses are provided on the frame walls. First recesses at an upper edge of the frame walls allow protruding elements of contact inserts to be inserted, while second recesses, in the form of openings, allow pin-like projections of the contact inserts to be engaged in a snap-fit ​​manner.

[0007] The object of the present invention is to provide a mounting frame, a connector and an electronic device which are characterized by a simplified design.

[0008] The problem is solved according to the invention by the features of the independent claims. Advantageous embodiments and further developments of the invention are specified in the dependent claims.

[0009] The mounting frame according to the invention is characterized in that the fastening area of ​​the wall segments each has at least one fastening tab projecting through the opening of a receiving section in the mounted position.

[0010] The wall segments can be arranged on the base frame. Each contact insert placed or inserted into the base frame is held or fastened to the base frame by two opposing wall segments. The mounted position is the position in which the wall segments are arranged on the base frame and contact inserts inserted into the interior of the base frame can be held by the wall segments. Preferably, a plurality of receiving sections are formed on each of the two side walls of the base frame. The receiving sections of a side wall are preferably arranged next to each other and thus in a row. The receiving sections are preferably at least partially formed into the respective side wall of the base frame. Each wall segment to be arranged on the base frame is assigned a receiving section, so that one wall segment can be arranged on each receiving section.According to the invention, each receiving section has an opening which, in the mounted position of the wall segments on the base frame, is at least partially overlapped by the mounting area of ​​the wall segment associated with the receiving section. The openings are preferably formed as through-holes in the base frame or in the side walls of the base frame. The openings preferably extend from the upper edge of the base frame into the base frame. The wall segments can be brought into operative contact with the contact inserts, in particular with the projecting elements of the contact inserts, via the openings in order to hold the contact inserts in the interior of the base frame. The projecting elements of the contact inserts can project into the respective opening for this purpose.In the assembled position, the openings are at least partially covered by the mounting area of ​​the respective wall segment, allowing the wall segments to overlap or overlap the end face of a protruding element of an inserted contact insert. By covering the end face of the protruding elements of the contact inserts with the wall segments, each wall segment can apply a force, particularly a compressive force, to the end face of its associated protruding element. This force is oriented transversely to the insertion direction of the respective contact insert into the base frame. This improves the positioning and, in particular, the alignment of the contact insert within the base frame.In particular, this allows the contact insert to be centered within the base frame, thus reducing any play between the contact insert and the base frame.

[0011] To enable correct positioning of the contact inserts, the openings on the first side wall of the receiving sections can be wider than those on the second side wall. The two projections on a contact insert also preferably have different widths, ensuring that the insert can only be inserted by placing the wider projection into the wider opening of a receiving section and the narrower projection into the narrower opening of a receiving section. This prevents incorrect insertion of the contact inserts into the base frame and thus into the retaining frame.

[0012] To hold the contact inserts in the desired position within the interior of the base frame, the mounting area of ​​the wall segments, according to the invention, each has at least one mounting tab that projects through the opening of a receiving section in the mounted position. The mounting tab can be designed such that, in the mounted position, the mounting tab can rest on the upper side of a protruding element of the respective contact insert, so that, in the insertion direction of the contact insert into the base frame, the mounting tab can prevent movement of the inserted contact insert against the insertion direction of the contact insert.

[0013] To achieve greater stability in holding the contact inserts in their position within the base frame, the mounting area of ​​the wall segments can have two mounting tabs that protrude through the opening of a receiving section when mounted. The two mounting tabs of a wall segment's mounting area can be symmetrical to each other.

[0014] The two mounting tabs of a wall segment's mounting area can be arranged on opposite outer edges of the wall segment. These two outer edges preferably define the boundaries of the respective wall segment. By arranging them on the outer edges, the mounting tabs can be configured as two wings on the wall segment.

[0015] The mounting tabs are preferably bent in the area where they connect to the respective outer edge. Preferably, the mounting tabs are bent outwards from the main plane of extension of the wall segments. Preferably, the mounting tabs can each be bent at an angle α ≥ 90° to the outer edge of the wall segment. The mounting tabs are thus bent towards the interior of the base frame. Particularly preferably, the mounting tabs can each be bent at an angle α ≥ 180° to the outer edge of the wall segment. When bent at an angle α ≥ 180°, the mounting tabs have an approximately U-shaped bend.

[0016] The receiving sections are preferably formed on an outer surface of the base frame facing away from the interior. In the assembled position, the wall segments thus preferably rest against the outer surface of the base frame. Preferably, no part or area of ​​a wall segment is located on an inner surface of the base frame facing the interior in the assembled position. The wall segments therefore no longer need to be elaborately curved, since it is no longer necessary to wrap around the lower edge of the base frame in the wall segments according to the invention.

[0017] The fastening area of ​​the wall segments can be formed at the head of each wall segment, which can be positioned at an end section of the wall segment opposite a foot. The fastening area and the foot of a wall segment thus preferably have the greatest possible distance between them.

[0018] The wall segments are preferably attached or held to their respective mounting section and thus to the base frame via their base. The wall segments are therefore preferably not attached to the base frame via their head or mounting area. In contrast to the base, the head or mounting area is preferably exposed relative to the base frame, so that there is preferably no contact between the head or mounting area of ​​the wall segment and the base frame in the assembled position.

[0019] The base of a wall segment can be attached to the mounting section or the base frame in various ways. For example, the attachment can be achieved using a snap-fit ​​connection, a rivet connection, and / or an adhesive bond between the wall segment and the base frame.

[0020] Particularly preferably, the fastening can be designed such that each receiving section has a slot-shaped recess into which the base of one of the several wall segments can be inserted in the mounted position. This allows the wall segments to be individually positioned and fastened to the base frame and thus individually to their respective receiving section. With such a fastening, the wall segments can also be attached to the base frame in pairs, allowing two or more wall segments to be positioned and fastened to their respective receiving sections simultaneously. By inserting at least their base into a slot-shaped recess of their respective receiving section, the mounting of the wall segments to the base frame can be particularly simple and quick. The design of the retaining frame can also be significantly simplified as a result.The slot-shaped recesses can each form a pocket on the base frame into which the wall segments, at least partially, can engage in the assembled position, specifically with their base. The base of the wall segments, which allows them to be inserted into the slot-shaped recess, is preferably located at one end of the wall segments.

[0021] The slot-shaped recesses of the mounting sections are preferably formed on a lower edge of the base frame. This allows the wall segments to be preferably attached to the base frame from below and inserted into the slot-shaped recesses. The mounting direction of the wall segments on the base frame is thus preferably opposite to the insertion direction of the contact inserts into the interior of the base frame, so that the wall segments can be inserted into their respective slot-shaped recesses in the opposite direction to the insertion of the contact inserts into the base frame. The contact inserts are preferably inserted into the interior of the base frame from above.

[0022] The slot-shaped recesses of the receiving sections formed on the first side wall can be interconnected, and / or the slot-shaped recesses of the receiving sections formed on the second side wall can be interconnected. 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 interconnected, they can form a single recess that spans all the receiving sections of that side wall. Such a slot-shaped recess can extend over more than two-thirds of the length of the side wall.

[0023] The wall segments are preferably designed to be spring-like. For this purpose, the wall segments can, for example, be made of spring steel. When a contact insert is inserted, the wall segments mounted on the base frame can spring outwards at their heads, away from the interior of the base frame, to allow the contact insert to be inserted. Once the contact insert is positioned in the desired position within the base frame, the mounting area of ​​the wall segments can spring back towards the interior of the base frame, thus holding the contact inserts in this position.

[0024] To achieve particularly good spring action, each wall segment can have a central section between the base and the head, with the width of this central section tapering from the base to the head. This tapering ensures uniform deformation of the wall segment, especially the central section, along its entire bending length when inserting and removing the contact inserts from the interior of the base frame. The tapering from the base to the mounting area also reduces the bending stress of the wall segment from this point. The base can form a clamping point for the wall segment on the base frame, particularly on a receiving section of the base frame.By reducing the width of the wall segment starting from the clamping point, the base of the wall segment, a uniform stress distribution can be achieved along the length of the wall segment when the wall segment flexes during the insertion and removal of the respective contact insert. Towards the head, the tapering increases the elasticity of the wall segment, creating a kind of flexible joint. Viewed along the length of the wall segment, the central section preferably has a significantly larger surface area than the base and the mounting area of ​​the wall segment.

[0025] In the central section, the outer edges of the wall segment are preferably not straight. Instead, the outer edges of the wall segment extending along the central section can have a curved shape. This curved shape of the outer edges further improves the distribution of bending stress within the wall segment, thus reducing the load acting on the wall segments during the insertion and removal of the contact inserts and simultaneously achieving optimized spring action of the wall segments.

[0026] To achieve a functional separation between the base and the middle section, an offset can be formed in the connection area of ​​the base to the middle section such that the base extends in a first plane and the middle section extends in a second plane offset from the first plane. In the assembled position, the base can thus be arranged within the base frame, in the slot-shaped recess. At the connection area of ​​the wall segment exhibiting the offset, the wall segment can extend out of the recess in the assembled position, so that the middle section, as well as the fastening area or the head of the wall segment, can be guided along the outside of the base frame and thus no longer engage in the slot-shaped recess of the receiving section.

[0027] The mounting sections can each have a contact surface against which an inner surface of the wall segments, facing the interior of the base frame, can lie flat in the mounted position. This flat contact of the wall segments with the respective mounting section via their central section ensures good and positionally stable support of the wall segments against the mounting sections and thus against the base frame. The contact surface preferably faces away from the interior of the base frame.

[0028] Particularly secure positioning of the wall segments on the base frame can be achieved by limiting the contact surface of a receiving section to two opposing inner edges. In the assembled position, the outer edges of the wall segments, in the area of ​​the central section, can form a positive fit against the inner edges of their corresponding receiving section. This reliably prevents lateral displacement of the wall segments, especially during the insertion and removal of the contact inserts, as the wall segments are supported on both sides by the outer edges and their movement is limited.

[0029] To further improve the attachment of the wall segments to the base frame, each wall segment can have a fastening element at its base which, in the mounted position, engages with an opening formed in the base frame. Each mounting section can have such an opening. The fastening elements can, for example, be in the form of a tab or a lug which, in the mounted position, can engage in an opening on the base frame or on the respective mounting section and lock or hook into place.

[0030] Furthermore, it is possible to attach an identification element to each wall segment. The identification element can be pre-labeled or can be individually labeled by the user. The identification elements can be used to identify the contact inserts or the slots for the contact inserts within the base frame. Preferably, the identification element can be attached to the base of the wall segment. For example, the identification element can be inserted into the slot-shaped recess along with the base to secure it. Alternatively, the identification element can also be glued to the wall segment. Using the identification element, the slots for the contact inserts can be individually labeled without increasing the required installation space for the mounting frame.

[0031] The wall segments can be designed as individual elements, or two or more wall segments arranged on a side wall can be connected to each other. The connected wall segments are then preferably formed in one piece.

[0032] The wall segments are preferably joined together at their base in one piece. If two or more wall segments are joined together, attaching them to the base frame can be done even faster.

[0033] The problem according to the invention is further solved by means of a connector which has a housing, a retaining frame arranged in the housing and several contact inserts received in the retaining frame, wherein the retaining frame is designed and further developed as described above.

[0034] Furthermore, the problem according to the invention is solved by means of an electronic device which has at least one connector as described above, developed and further refined.

[0035] The invention is explained in more detail below with reference to the accompanying drawings and preferred embodiments.

[0037] Fig. 2 bis 7 Each shows a schematic representation of a holding frame 100, which can be arranged in a housing of a connector.

[0038] The retaining 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 each other. The two end walls 13, 14 are also arranged parallel to each other. 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 define an interior space 15 of the base frame 10. Contact inserts 200 can be inserted into this interior space 15 in the insertion direction E, as is the case, for example, in Fig. 6 It is shown how to be inserted and attached.

[0039] The contact inserts 200 are attached via wall segments 16 arranged on the base frame 10, as are used in particular in the Fig. 1a und 1b The wall segments 16 arranged on a base frame 10 are all identical. In the base frame 10 shown here, four such wall segments 16 are arranged, with two wall segments 16 on the first side wall 11 and two wall segments 16 on the second side wall 12.

[0040] Fig. 1a shows a top view of an outer surface 17 of a wall segment 16, which in the position mounted on the base frame 10 is directed away from the interior 15 of the base frame 10.

[0041] Fig. 1b shows a top view of an inner surface 18 of the wall segment 16, which in the position mounted on the base frame 10 points towards the interior 15 of the base frame 10.

[0042] The wall segments 16 are each designed to be spring-elastic. The wall segments 16 can be made of spring steel.

[0043] The wall segments 16 each have a base 19, a head 20, and a middle section 21 located between the base 19 and the head 20. Along the length of the wall segment 16, viewed from the base 19 to the head 20, the middle section 21 has a significantly larger area than the head 20 and the base 19. The base 19 is formed at a first end section of the wall segment 16, and the head 20 is formed at a second end section of the wall segment 16 opposite the first end section.

[0044] The wall segment 16 has its greatest width BF at the base 19. At the head 20, the wall segment 16 has its smallest width BK. In the middle section 21, the wall segment 16 tapers, with its width BM decreasing from the base 19 to the head 20. This tapering of the width BM of the middle section 21 from the base 19 to the head 20 ensures uniform deformation of the wall segment 16 along its length during insertion and removal of the contact inserts 200.

[0045] In the area of ​​the middle section 21, the outer edges 22, 23 of the wall segment 16 are not straight, but have a curved shape along the length of the middle section 21 and thus from the foot area 19 to the head area 20.

[0046] In the connection area 24 of the foot section 19 to the middle section 21, an offset is formed such that the foot section 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 essentially parallel to each other.

[0047] The foot area 19 has two laterally formed shoulder surfaces 25, 26, both of which, in the mounted position of the wall segment 16 on the base frame, can engage in a slot-shaped recess 27 of a receiving section 35 formed on the base frame 10, as is the case, for example, in Fig. 5 This can be seen. The two shoulder surfaces 25, 26 project laterally outwards in such a way that they overlap or protrude laterally over the middle section 21 and the head region 20.

[0048] Furthermore, the foot section 19 has a fastening element 28 which can engage in an opening 29 formed in the base frame 10. The fastening element 28 is designed here as a tab sheared out from the foot section 19, which is bent towards 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 located at the center of the width BF of the foot section 19.

[0049] A fastening area 30 is formed on the head region 20, by means of which a contact insert 200, inserted into the interior 15, can be held in the interior 15. The fastening area 30 has two fastening tabs 31, 32. In the mounted position of the wall segment 16 on the base frame 10, the fastening tabs 31, 32 extend towards the interior 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 wall segment 16. Fig. 1a, 1b In the illustrated embodiments, the fastening tabs 31, 32 are each bent at an angle α of approximately 90° to the outer edge 22, 23 of the wall segment 16. The fastening tabs 31, 32 are bent towards the interior 15 of the base frame 10. The fastening tabs 31, 32 thus project from the main extension plane of the wall segments 16.

[0050] The lower edges 33 of the mounting tabs 31, 32, with which the mounting tabs 31, 32 rest on the projecting elements 210 of the contact inserts 200 in order to hold the contact inserts 200 in the interior 15 of the base frame 10, are essentially straight. The upper edges 34 of the mounting tabs 31, 32, opposite the lower edges 33, are, however, inclined, so that the upper edges 34 can form an insertion chamfer in the direction E of insertion of the contact inserts 200 into the interior 15 of the base frame 10.The chamfered edge allows the contact inserts 200, and in particular the projecting elements 210 of the contact inserts 200, to slide along the upper edge 34 of the two mounting tabs 31, 32 during insertion, thereby bending the wall segments 16 outwards. This causes the wall segments 16 to spring outwards, exposing the interior 15 of the base frame 10. This allows the contact inserts 200, with their projecting elements 210, to be inserted into the interior 15 of the base frame 10. Once the contact inserts 200 are inserted into the interior 15, the wall segments 16 spring back automatically until their lower edge 33 rests on the projecting elements 210, thus holding the contact inserts 200 in the interior 15 of the base frame 10.

[0051] As in Fig. 2 As can be seen, the base frame 10 has a receiving section 35 for each wall segment 16. The receiving sections 35 are formed on an outer surface 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 on both the first side wall 11 and the second side wall 12.

[0052] Each receiving section 35 has a slot-shaped recess 27 into which the foot section 19 of the respective wall segment 16, with its two shoulder surfaces 25, 26, can be inserted. In the embodiment shown here, 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 section 35 of the second side wall 12 are connected to each other, as shown in Fig. 5 It can be seen 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.

[0053] The recesses 27 of the receiving sections 35 are formed on a lower edge 37 of the base frame 10. The wall segments 16 can therefore be attached to the base frame 10 from below along a mounting direction M. The wall segments 16 can thus be attached to the base frame 10 opposite to the insertion direction E of the contact inserts 200 into the interior 15 of the base frame 10.

[0054] 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 outer surface 36 of the base frame 10 by forming a kind of recess on the outer surface 36 of the base frame 10. In the assembled position, the respective wall section 16 with its central section 21 lies flush against the contact surface 38. The contact surfaces 38 are each bounded by two opposing inner edges 41, 42, whereby in the assembled position the outer edges 22, 23 of the respective wall segment 16 abut the inner edges 41, 42 in a form-fitting manner. The inner edges 41, 42, like the outer edges 22, 23, thus have a curved shape. The inner edges 41, 42 are preferably formed to such a height that, in the assembled state, the wall segments 16 are flush with the outer surface 36 of the base frame 10.The inner edges 41, 42 offset the mounting surface 38 of the receiving sections 35 in the direction of the interior 15 of the base frame 10 relative to the outer surface 36 of the base frame 10.

[0055] Above the mounting surface 38, the receiving sections 35 each have an opening 39 extending from an upper edge 40 of the base frame 10 into the respective side wall 11, 12 of the base frame 10. In the mounted position of the wall segments 16, the mounting area 30 or the head area 20 of the respective wall segment 16 overlaps the opening 39, at least partially. The mounting tabs 31, 32 can project into the opening 39. In the area of ​​the opening 39, the mounting tabs 31, 32 can hold the contact inserts 200 in place by resting on the projecting elements 210 of the contact inserts 200, which project into the opening 39, as shown in particular in Fig. 6 can be seen.

[0056] As particularly 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.

[0057] Fig. 3 Figure 1 shows the assembly of one of the wall segments 16 on the base frame 10 by inserting the wall segment 16 into the slot-shaped recess 27 in the assembly direction M, whereby in particular the two shoulder surfaces 25, 26 of the foot section 19 are inserted into the slot-shaped recess 27 and thus engage in the slot-shaped recess 27. With its central section 21, the wall segment 16 slides along the contact surface 38. The wall segments 16 are inserted until the fastening element 28 of the foot section 19 engages in the opening 29 on the base frame 10, as shown in Figure 2. Fig. 4 This can be seen. In this assembled position, the head area 20 or the fastening area 30 of the wall segment 16 is located in the area of ​​the opening 39 in order to overlap it at least partially.

[0058] Once the wall segments 16 are mounted on the base frame 10, the contact inserts can be inserted into the interior 15 of the base frame 10 in the insertion direction E. The contact inserts 200, with their projection elements 210, slide along the upper edges 34 of the mounting tabs 31, 32, causing these tabs and thus the mounting area 30 to spring outwards to allow the projection elements 210 to pass the mounting tabs 31, 32. Once the contact inserts 200 have passed the mounting tabs 31, 32, they can spring back towards the interior 15 until they rest on top of the projection element 210, as shown in the figure. Fig. 6 and 7This can be seen.
