Description

The invention relates to a holding frame for a connector for receiving contact inserts. The invention further relates to a connector with such a holding frame.

Such holding frames are used for modular use of contact inserts, for example on connectors. One or more 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 contact inserts can have, for example, one or more electrical contacts. In this case, the contact inserts are connected, on the one hand, to electrical lines which 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 contact.

Such modular contact inserts offer the advantage of flexible combinability and thus a variable use of connectors.

If contact inserts are inserted into a holding frame, it is necessary for the contact inserts 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 contact inserts. With one from the DE 10 2012 110 907 A1 Known holding frame 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 contact inserts, in order in this way to lock projection 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 the frame walls of two recesses. Projection elements of contact inserts can be inserted into first recesses on an upper edge of the frame walls, while peg-like formations of the contact inserts can be latched into engagement with second recesses in the form of openings.

The object of the present invention is to provide a holding frame which enables simple insertion of contact inserts on the holding frame and reliable locking of the contact inserts on the holding frame with simultaneous easy removal of the contact inserts from the holding frame.

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

The holding frame according to the invention is characterized by 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, the first side wall, the second side wall, the first end wall and the second end wall encloses an interior of the base frame, into which the contact inserts can be inserted along an insertion direction, and is characterized by a plurality of wall segments which have an inner surface facing towards the interior and an outer surface facing away from the interior, and which, in a fastening position, face the interior of the base frame insert inserted contact inserts on the base frame, openings being formed on the first side wall and on the second side wall, with one of the plurality of wall segments in each opening for transfer into the fastening position and into an oven fenposition is pivotally mounted.

According to the invention, it is now provided that the wall segments, by means of which the contact inserts can be fastened to the base frame and thus to the holding frame, are no longer arranged in a fixed position on the base frame, but rather are arranged to be movable relative to the base frame, so that the wall segments are relative to the base frame can be pivoted or tilted into the fastening position and the open position. In the fastening position, the wall segments are preferably aligned with the respective side wall of the base frame on which they are positioned. In the fastening position, contact inserts inserted into the interior can be held in a fixed position on the wall segments, since the projection elements of the contact inserts can be in engagement with the recesses formed on the wall segments. When the wall segments are transferred from the fastening position into the open position, the wall segments are pivoted away from the interior in one direction, so that the wall segments in the open position out of the respective plane Side wall are tilted out. For example, in the open position, the wall segments can be tilted out of the plane of the respective side wall at an angle between 3 ° and 15 °, preferably between 5 ° and 10 °. By pivoting away or tipping away the wall segments when moving into the open position, the insertion area for the contact inserts into the interior of the base frame is enlarged or widened in the open position, so that the contact inserts can be inserted into the interior without a hindrance. Detaching and removing the contact inserts from the interior of the base frame is also easily possible in the open position of the wall segments, since the wall segments can be pivoted away or tilted away from the contact inserts. The pivotable mounting of the wall segments can be designed such that each wall segment can be pivoted individually. However, it is also possible for two or more wall segments arranged on a side wall to be connected or coupled to one another in such a way that these wall segments can be pivoted together. In the event of a possible pivoting movement of the wall segments individually, individual contact inserts can be inserted individually into the holding frame, independently of other contact inserts, and can also be detached therefrom.

Due to the pivotable mounting of the wall segments on the base frame, the wall segments can now preferably be formed from a dimensionally stable material. Rigid means here that the wall segments themselves are not deformable and thus maintain their shape in any position and do not change. The wall segments are preferably rigid. The wall segments therefore preferably have no spring action or no spring elasticity.

The base frame and the wall segments can be formed from the same material. The base frame is preferably made of a rigid, dimensionally stable material, so that the wall segments can then also be made of a rigid, dimensionally stable material. If the base frame and the wall segments are made of the same material, the compatibility and handling when mounting the wall segments on the base frame can be improved. In addition, the manufacturing effort can be reduced if the base frame and the wall segments are made of the same material.

The wall segments are preferably formed from a die-cast material. Due to the formation of a die-cast material, the wall segments can have a particularly smooth, clean surface without edges. In addition, particularly small wall thicknesses can be achieved when using a die-cast material. For example, an aluminum die-cast material or a zinc die-cast material can be used as the die-cast material. If the base frame is made of the same material as the wall segments, the base frame can also be made of a die-cast material.

To form a pivotable mounting of the wall segments, the wall segments are preferably pivotally mounted about an axis of rotation in the openings on the base frame or on the side walls of the base frame. The axis of rotation about which the wall segments can be pivoted or tilted is preferably arranged or formed off-center of the wall segments. The axis of rotation is preferably arranged or formed at a lower end of the wall segments. In the assembled state of the wall segments, the lower end of the wall segments is arranged closer to a lower edge of the base frame than an upper end of the wall segments. The upper end of the wall segments is preferably arranged adjacent to an upper edge of the base frame. A recess is preferably formed in the upper region of the wall segments, in each of which a projection element of the contact inserts inserted into the interior can be held in the fastening position. The axis of rotation can be designed as an axle body, which can be connected as a separate component to the wall segments and the base frame. Furthermore, the axis of rotation can also be formed by pivot pins formed in one piece on the wall segments, wherein the pivot pins can engage in recesses formed on the base frame and can be rotatably mounted in these recesses.

It can preferably be provided that each wall segment has its own axis of rotation. If each wall segment has its own axis of rotation, then each wall segment can be transferred individually and thus individually into the fastening position and into the open position without adjacent wall segments also being transferred into the respective position. The contact inserts can thus also be individually inserted and fastened in the holding frame or detached from the holding frame.

Furthermore, it is also possible that two or more wall segments arranged on the first side wall and / or on the second side wall can be pivotably mounted in the openings of the base frame or the side walls of the base frame via a common axis of rotation. The axis of rotation is then preferably in the form of an axle body which extends through two or more of the wall segments can. A coupling of two or more wall segments of a side wall is then possible via the axis of rotation, so that the wall segments do not have to be transferred individually into the fastening position and into the open position, but two or more wall segments at the same time by actuating only one of the wall segments into the fastening position and in the open position can be transferred.

In order to make it easier to insert the contact inserts into the interior and thus into an area between two opposing wall segments, the wall segments can each have an insertion bevel on their inner surface. The insertion bevel is preferably formed at the upper end of the wall segments. The insertion bevel is preferably formed in the insertion direction above the respective recess formed in the wall segment.

To hold the wall segments in the fastening position, the wall segments can each have a fastening region, which in the fastening position can interact with counter-fastening regions formed on the base frame. The fastening area of the wall segments is preferably formed at the upper end of the wall segments. The fastening region can be designed as a latching region and have the shape of a latching lug, for example. The counter-fastening area can be designed as a counter-latching area and have the shape of, for example, a rear grip, in which case the latching lug can hook or snap back on the rear grip in the fastening position.

In addition or as an alternative to the fastening areas and counter-fastening areas, at least one holding means can be fastened to the base frame in order to hold the wall segments in the fastening position, said holding means being able to grip around one or more of the wall segments at least in regions in the fastening position. The holding means is preferably an additional or separate component, which can be attached to the base frame after the insertion and positioning of the contact inserts in the holding frame. The holding means is preferably designed such that it can encompass both a partial area of the base frame and a partial area of one or more wall segments, so that the respective wall segments can be held in a fixed position relative to the base frame by means of the holding means.

For example, the at least one holding means can be designed in the form of a fastening rail, which can be placed or pushed onto an edge section of the base frame in such a way that, in the fastening position, the holding means can encompass the edge portion of the base frame and an edge portion of one or more of the wall segments at least in regions . The edge section of the base frame, on which the holding means can be pushed, is preferably formed on the upper edge of the base frame. The holding means in the form of a fastening rail preferably has a C-shaped cross section or U-shaped cross section, so that the base frame and also wall segments arranged in the fastening position can be encompassed in a C-shaped or U-shaped manner in the fastening position. The holding means designed as a fastening rail are preferably straight and elongated. Two holding means can preferably be provided, it being possible for a first holding means in the form of a fastening rail to be arranged on the first side wall of the base frame and a second holding means in the form of a fastening rail to be arranged on the second side wall of the base frame.

Furthermore, it is possible for the at least one holding means to be designed in the form of a tensioning element which, in the fastening position, can grip around the base frame on an outer surface facing away from the interior and the wall segments on its outer surfaces. If the wall segments are arranged in the fastening position after insertion of the contact inserts, the holding means designed as a tensioning element can be arranged on the base frame. However, it is also possible for the holding means designed in the form of a clamping element to be mounted on the base frame before the contact inserts are inserted. The holding means designed as a tensioning element encompasses the base frame preferably over its entire circumferential surface or its entire outer circumferential surface, so that all the wall segments arranged on the base frame can be encompassed with one holding means. If the holding means is mounted on the base frame prior to the insertion of the contact inserts, the holding means can provide a spring action, by means of which the holding means can apply an automatic restoring action to the wall segments when the wall segments are in a position, whereby the wall segments automatically move from the open position to the Mounting position can be pivoted back.

The tensioning element can be, for example, an elastically designed polymer element or a metal spring element. The tensioning element thus preferably has an elastic effect or spring action, as a result of which the mounting of the tensioning element on the base frame and on the wall segments can be facilitated. If the tensioning element is an elastically designed polymer element, it can, for example, be similar to a rubber band be trained. The polymer element can be formed, for example, from a rubber material or a plastic material. If the tensioning element is a metal spring element, it can be designed, for example, in the form of a spring ring, such as a spiral spring ring.

In order to facilitate the assembly of the contact inserts on the holding frame, the wall segments can each have at least one nose protruding towards the interior on their inner surfaces, which can cooperate with the insertion of the contact inserts in order to transfer the wall segments from the open position into the fastening position. Because the lugs protrude into the interior, the contact inserts can exert a compressive force on the lugs when inserted into the interior, as a result of which the wall segments can be pivoted from the open position into the fastening position. This makes it possible to trigger the movement of the wall segments from the open position to the fastening position by means of the contact inserts, so that an additional manual movement of the wall segments from the open position to the fastening position is no longer necessary. The lugs are preferably arranged at the lower end of the wall segments, so that the wall segments are actuated by the contact inserts when the contact inserts have almost reached their end position in the interior of the base frame.

Furthermore, it can be provided that at least one spring element is arranged on the base frame, which can cooperate with one or more of the wall segments in such a way that the pivoting movement of the wall segments from the fastening position into the open position enables the at least one spring element to be transferred into a prestressed position. Due to the prestressing effect of the spring element in the open position of the wall segments, the spring force acting on the wall segments can automatically pivot the wall segments back from the open position into the fastening position as soon as the contact inserts are inserted into the interior. The one or more spring elements are preferably designed such that they are attached to the base frame and span at least in regions one or more wall segments.

For example, the at least one spring element can be fastened to a lower edge of the base frame and the at least one spring element can have spring tabs that interact with the wall segments, wherein the spring tabs can each be held on the inner surfaces of the wall segments. The spring element can, for example, have a connecting web, which can be attached to the lower edge of the base frame. The connecting web can be U-shaped, so that the connecting web can grip around the lower edge of the base frame. The spring tabs can each be integrally formed on the connecting web. A spring tab is preferably provided for each wall segment. The spring tabs can engage or be hooked on the wall segments, in particular on the inner surface of the wall segments, so that the spring tabs can be fastened to the wall segments and can exert a spring effect when the wall segments move into the fastening position and into the open position. The spring element can, for example, be cut and bent from a spring plate.

Alternatively, the spring elements can be designed such that a spring element is assigned to each wall segment, wherein the spring elements can each span the outer surface of one of the wall segments. When the wall segments move from the fastening position into the open position, the respective spring element can be tensioned, since the wall segments can press against the respective spring element and deflect it. The spring elements preferably each extend over a partial area of the outer surface of the wall segments.

The spring elements preferably each extend along the width of the wall segments.

The spring elements are then preferably formed from a bent wire. A spring element can be formed in a simple manner by means of the wire. A spring element formed from a bent wire can, for example, be fastened to the axis of rotation or to the pivot pins formed on the wall segments and span the respective wall segment in the width direction.

The object according to the invention is further achieved by means of a plug connector which has a housing, a holding frame arranged in the housing and a plurality of contact inserts accommodated in the holding frame, the holding frame being designed and developed as described above.

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

1 shows a schematic representation of a holding frame 100 , which can be arranged in a housing of a connector.

The holding frame 100 has a basic framework 10 on which is integrally formed. The base frame has a first side wall 11 , one of the first side wall 11 opposite second side wall 12th , a first end wall 13 and one of the first end wall 13 opposite second end wall 14 on. The two side walls 11 , 12th 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 at a 90 ° angle to the side walls 11 , 12th arranged. The two side walls 11 , 12th and the two end walls 13 , 14 together enclose or delimit an interior space 15 of the basic framework 10 . In this interior 15 can contact inserts 200 in the direction of insertion E , as it is for example in 5 is shown, inserted and attached.

The attachment of the contact inserts 200 takes place on the base frame 10 arranged wall segments 16 . Every wall segment 16 has a recess 17th in which a projection element 210 a contact insert 200 can snap into place when the contact inserts 200 in the interior 15 of the basic framework 10 are introduced.

For every wall segment 16 is in the basic frame 10 an opening 18th formed in which a wall segment 16 can be arranged. In 1 is an opening 18th without such a wall segment 16 shown. In the other openings 18th is a corresponding wall segment 16 arranged.

The wall segments 16 are in the openings 18th pivoted so that the wall segments 16 can be pivoted or tilted into an open position and into a fastening position. In 1 are the three in the openings 18th arranged wall segments 16 positioned in the mounting position. The wall segments are in the fastening position 16 aligned with the respective side wall 11 , 12th of the basic framework 10 at which they are positioned. In the fastening position, you can look into the interior 15 introduced contact inserts 200 on the wall segments 16 be held in a fixed position. In the open position, such as this one in 2nd on one of the four wall segments 16 is shown are the wall segments 16 in one direction from the interior 15 swiveled away or tilted. In the open position is due to the pivoted or tilted position of the wall segments 16 The interior 15 in the area of the respective wall segment 16 enlarged, in particular widened, so that insertion of the contact inserts 200 can be facilitated without the wall segments 16 must be deformed themselves. The wall segments 16 can be formed from a dimensionally stable material, so that the wall segments 16 are rigid and cannot be deformed. The wall segments 16 can be made of the same material as the base frame 10 be trained. The wall segments 16 and the basic framework 10 can be formed from a die-cast material.

The pivotable mounting of the wall segments 16 is through an axis of rotation 19th reached. At the in 1 The configuration shown is the axis of rotation 19th an axle beam 20 which in the base frame 10 is attached. The axle beam 20 extends here over the entire length of the respective side wall 11 , 12th so that the axle beam 20 across all openings 18th a side wall 11 , 12th extends. The wall segments 16 a side wall 11 , 12th are here on a common axle beam 20 arranged and thus over a common axis of rotation 19th coupled with each other. The one on a side wall 11 , 12th arranged wall segments 16 thus perform the same movement so that all wall segments 16 a side wall 11 , 12th can be transferred to the open position and the fastening position at the same time. On each side wall 11 , 12th is an axis of rotation 19th or an axle beam 20 arranged.

Alternatively, it is also possible that the axle beam 20 in a fixed position on the base frame 10 is arranged. With such a configuration, the wall segments 16 rotatable on the axle beam 20 be arranged so that the wall segments 16 can be transferred separately from one another into the open position and into the fastening position.

3rd shows a sectional view through the base frame 10 and through two wall segments 16 . It can be seen here that the wall segments 16 one through hole each 25th have within which the axis of rotation 19th is formed and the axle beam 20 is led.

The axis of rotation 19th or the axle beam 20 are at a lower end 21st of the wall segments 16 arranged. The bottom end 21st is in the direction of insertion E below the top 22 of the wall segments 16 educated.

Every wall segment 16 points here towards its interior 15 pointing inner surface 23 an insertion slope 24th to insert the contact inserts 200 to facilitate. The lead-in chamfer 24th is at the top 22 of the wall segments 16 arranged. The lead-in chamfer 24th is above the recess 17th on the respective wall segment 16 educated.

In the fastening position, the wall segments can 16 at their top end 22 be latched by on the wall segments 16 trained attachment areas 26 with the base frame 10 trained counter-fastening areas 27 can work together. The fastening areas formed here as rest areas 26 can be designed in the form of locking lugs, which on the counter-fastening areas formed here as counter-locking areas 27 , which can be designed in the form of undercuts, hook or hook. The attachment areas 26 are at the top 22 of the wall segments 16 , especially at one at the top 22 trained edge section 28 of the wall segments 16 arranged. The counter fastening areas 27 are on one adjacent to the top edge 29 of the basic framework 10 trained edge section 30th of the basic framework 10 arranged.

Around the wall segments 16 in a fixed position relative to the base frame 10 To be able to hold in the fastening position can one or more holding means 31 be provided.

The holding means formed in the form of a fastening rail 31 has a C-shaped or U-shaped cross section and encompasses the edge section 30th or the top edge 29 of the basic framework 10 as well as the wall segments 16 at their edge sections 28 at the top 22 . The holding means designed as a fastening rail 31 borders at the in 4th shown configuration in the pushed-on state to the recesses 17th of the wall segments 16 so that the recesses 17th just not from the holding means 31 be covered.

At the in 5 shown sectional view can be seen that on the inner surface 23 of the wall segments 16 one or more each towards the interior 15 protruding noses 32 are formed, which when inserting the contact inserts 200 cooperate with these to the wall segments 16 to be transferred from the open position to the fastening position. This in 5 left wall segment 16 is positioned here in the open position and that in 5 wall segment arranged on the right 16 is positioned here in the fastening position. When inserted into the interior 15 is by means of the contact inserts 200 on the nose 32 a compressive force is applied, creating the wall segments 16 can be pivoted from the open position to the fastening position. This triggers the movement of the wall segments 16 from the open position to the Mounting position using the contact inserts 200 possible, so that an additional manual movement of the wall segments 16 from the open position to the fastening position is no longer necessary. The noses 32 are here at the bottom 21st of the wall segments 16 arranged so that an actuation of the wall segments 16 through the contact inserts 200 takes place when the contact inserts 200 almost their final position in the interior 15 of the basic framework 10 achieved.

6 and 7 show an embodiment with a holding means 33 to hold the wall segments 16 in the fastening position, which is in the form of a tensioning element, which in the fastening position is the base frame 10 on an outside surface 34 of the basic framework 10 and on the outer surfaces 35 of the wall segments 16 embraces. The holding device 33 is ring-shaped here. For safe and defined absorption of the holding device 33 is on the outer surface 34 of the basic framework 10 and on the outer surfaces 35 of the wall segments 16 a circumferential groove 36 trained in which the holding means 33 can be positioned. An unintentional slipping of the holding device 33 from the base frame 10 and the wall segments 16 can be done by inserting the holding device 33 in the groove 36 be prevented. In 7 is the holding device 33 in one on the base frame 10 fortified position shown. The holding device 33 is on the wall segments 16 at their top end 22 and close to the top edge 29 of the basic framework 10 positioned.

So that the wall segments 16 automatically after inserting the contact inserts 200 can pivot or tilt from the open position into the fastening position, the wall segments 16 by means of spring elements 37 , 38 as in the 8th to 14 is shown to be biased in the open position.

At the in 8th to 10 The configuration shown is the spring element 37 on a lower edge 39 of the basic framework 10 or a side wall 11 , 12th of the basic framework 10 arranged. As in 9 can be seen, the spring element 37 a connecting bridge 40 on which one at the bottom edge 39 of the basic framework 10 or the respective side wall 11 , 12th can be attached. The connecting bridge 40 is U-shaped, so that the connecting web 40 the bottom edge 39 of the basic framework 10 can embrace. At the connecting bridge 40 are several spring tabs 41 molded in one piece. The spring tabs 41 extend into the interior 15 of the basic framework 10 inside. For every wall segment 16 a side wall 11 , 12th the base frame is a spring tab 41 provided, which is based on the connecting web 40 down to the respective wall segment 16 extends so that the spring tab 41 with the respective wall segment 16 can be connected. The spring tabs 41 can on the wall segments 16 , especially on the inner surface 23 of the wall segments 16 intervene or be hooked so that the spring tabs 41 on the wall segments 16 can be attached and when the wall segments move 16 can apply a spring action in the fastening position and in the open position, as in the sectional view in 10 can be seen. On the inside surface 23 of the wall segments 16 is an assault 42 formed on which a free end portion 43 the spring tabs 41 can intervene. The free end section 43 is in the direction of the respective wall segment 16 bent to the rear handle 42 to be able to hook up. As in 10 can be seen when moving the wall segments 16 in the open position the spring tab 41 stretched and deflected so that a preload on the wall segment 16 can be applied. On each of the two side walls 11 , 12th is such a spring element here 37 arranged.
