Description

[0001] The invention relates to a multi-part connector having the features in the preamble of the main claim.

[0002] Such a multi-part connector is known from DE 10 2008 048 998 B4. The bridge is loosely inserted into the plug-in shell and is clamped to the shell base by the bridge web edges between the base studs and the adjacent shell web. The connection of the plugged-together connector parts is insecure.

[0003] DE 20 2004 004 734 U1, EP 2 027 355 B1, and EP 2 134 916 B1 show other forms of multi-part connectors, in which the bridges plugged into the plug-in shell rest on the shell base with the lower edge of their lateral bridge webs and are locked to the shell webs by lateral studs on the bridge webs. The protruding studs engage in recesses below cut-out retaining elements of the shell webs. A separate guide device for the connector parts is not provided.

[0004] DE 20 2017 101 315 U1 and EP 1 785 575 A2 show one-piece connectors without a bridge.

[0005] The object of the present invention is to demonstrate an improved connector technology.

[0006] The invention solves this problem with the features in the independent claims for the connector and the plug connection.

[0007] The claimed connector technology, i.e. the connector, its connector parts, the plug connection and the connection method have various advantages.

[0008] In addition to a locking device, the claimed connector has an additional guide device for its connector parts. The guide device is provided separately. It is spatially and functionally separate from the locking device.

[0009] The guide device can be provided and configured to guide the connector parts during mating in a mating direction and also in the mated position. The mating direction can be oriented transversely to the shell base, in particular transversely to its main plane. It can preferably be oriented perpendicularly to the shell base, in particular perpendicular to its main plane. The guide device can hold the mated connector parts relative to each other in the direction of their longitudinal axis. The holding function can be effective in the mated final position and also prior to mating the connector parts.

[0010] The locking device and the additional, separate guide device offer the advantage that the mated connector parts, i.e., the plug-in shell and the bridge, have a better, more precise, and more resilient connection. The guide device also improves handling and alignment, or rather, the mutual positioning of the connector parts during mating. The correct mating position and the locking device can be found more quickly and reliably. These advantages also apply to the stressed plug connection.

[0011] The high load-bearing capacity is particularly advantageous when inserting the multi-part connector into a hollow profile and the forces that occur during this process. This applies both to the so-called pre-insertion of the connector into a hollow profile and to the insertion of hollow profiles or hollow profile ends onto the connector from both sides. The connector parts remain in their relative positions and are not displaced or even separated by the insertion forces.

[0012] Positive aspects arise from the tight butting of the hollow profile end faces at a joint near the connector center, which improves the seal. The inserted bridge is located at least near the connector center and at the joint. The leakage of granulated desiccant from a hollow profile at the joint into the interior of the insulating glazing can be reliably prevented. Gas tightness is also improved.

[0013] Furthermore, this results in improved mechanical stability of the connector against external forces or moments, such as bending moments during transport of a closed spacer frame. At the same time, the tolerance tolerance of the multi-part connector and its adaptability to the given dimensions of the hollow profile(s) are improved. Tolerances can occur in the height and / or width of the connector connection. This is particularly advantageous for warm-edge hollow profiles, which have particularly good thermal insulation properties.

[0014] The locking device and the separate guide device each have interacting locking elements and interacting guide elements. The locking elements and guide elements are arranged at a spatial distance from each other and are functionally separate. A positive-locking interaction between the locking elements and the guide elements is advantageous.

[0015] Said guide elements and said locking elements can be arranged at a mutual distance transverse to the longitudinal axis and, if applicable, transverse to the shell base of the connector. Accordingly, the locking devices and the guide devices are spaced apart from each other, which ensures a particularly favorable overall connection of the mated connector parts.

[0016] The guide device, which is preferably located at the front in the plug-in direction, can act first when the connector parts are plugged together and can serve as a guide for the subsequent precise alignment and closure of the interacting locking elements and the locking function. The guide device can be easily located and closed when the connector parts are plugged together. It also has a positioning function for the connector parts.

[0017] For the guiding and guiding function, it is advantageous if the interacting guide elements each have a stop edge and an associated stop side, which interact for guiding purposes and are each aligned transversely to the shell base. In particular, the stop edges and stop sides of the interacting guide elements can be aligned parallel to each other and preferably along the insertion direction. They can also be aligned diagonally to the insertion direction.

[0018] In an advantageous embodiment, the interacting guide elements are spaced a greater distance from the shell base of the connector than the interacting locking elements. Furthermore, it is advantageous to arrange the interacting guide elements and the interacting locking elements in the region of an axial connector center of the connector.

[0019] The inserted bridge is located at least in the area of ​​the connector center. From there, it can extend along the longitudinal axis in both directions. The bridge can be significantly shorter than the plug-in shell and can act primarily at the joint and in the adjacent surrounding area on both sides of the hollow profiles. The connector can be divided into two connector legs, which extend from the connector center in different directions along the longitudinal axis. The multi-part connector is preferably designed as a straight connector. Alternatively, it can have an angled shape and be designed as a corner connector.

[0020] The guide device, in particular the interacting guide elements, can be designed to hold the mated connector parts relative to each other in the direction of the longitudinal axis. This can be achieved with a stop function, in particular a preferably two-sided stop function. The guide device and the guide elements can allow limited relative mobility of the connector parts in the direction of the longitudinal axis.

[0021] In a preferred embodiment, the guide device and the guide elements position the mated connector parts with a stop function that acts bilaterally along the longitudinal axis. The bridge and the plug-in shell can thus have a predetermined and precise mutual position, which can be assumed without play or at least with minimal play. This is advantageous for absorbing forces and resistance when inserting the connector into a hollow profile and for the aforementioned guiding function.

[0022] In an advantageous embodiment, the guide elements and the guide device can mutually support the mated connector parts against compressive forces in a direction transverse to the longitudinal axis and, if necessary, transverse to the shell base. This is particularly advantageous when the connector accommodates height tolerances of the hollow profile(s). Such compressive forces are often introduced from the outside onto the bridge and are directed against the shell base of the plug-in shell. The support function of the guide device can be present in addition to a support function of the locking device or can replace a possibly missing support function of the locking device.

[0023] The cooperating locking elements and the locking device can prevent the mated connector parts from being lifted off and released at least in a direction transverse to the longitudinal axis of the connector, in particular counter to the plugging direction. This can be achieved by a stop connection or a snap-in connection. The locking elements and the locking device can also mutually position and / or support the mated connector parts in a direction along and transverse to said longitudinal axis and, if necessary, transverse to the shell base. For this purpose, a design of the locking device as a positive snap-in connection is advantageous. The locking elements and the locking device can also support the bridge with contact or, preferably, at a distance from the shell base in a direction transverse to the longitudinal axis.

[0024] The guide device and the locking device, as well as their interacting guide elements and locking elements, can be designed and arranged differently with respect to the connector parts. In the plug-in shell, it is advantageous to arrange the one or more guide elements and the one or more locking elements on one or both shell webs.

[0025] In the bridge, the one or more guide elements and the one or more locking elements can each be arranged on one or both longitudinal sides, preferably on the outside of one or both bridge webs. The guide element(s) can be arranged near the bridge roof, and the locking element(s) can be arranged at a distance below the bridge roof. In the case of plugged-together connector parts, the interacting locking elements are arranged below the interacting guide elements and closer to the shell floor.

[0026] One or more of the interacting guide elements of the bridge and the plug-in shell can be arranged at the connector center and / or at least one of the axially adjacent connector areas or connector legs on both sides. An arrangement at the connector center has the advantage of stabilizing and supporting the connector and its connector parts at the connector center and is also beneficial for a centering guide function when plugging the connector parts together.

[0027] In an advantageous embodiment, in a plug-in shell, the guide element(s) can be arranged on a free edge of one or both shell webs. The locking elements can be arranged on the shell web at a distance below the free edge. The one or more guide elements of the plug-in shell can each be designed as a recess on the free edge of the shell web(s) and have an access opening facing away from the shell base. The guide element(s) on the bridge can be inserted here when the connector parts are plugged together. The recess can, for example, have a U-shape or V-shape in side view or another suitable shape.

[0028] The guide device can comprise a central guide element at the connector center, arranged on one or both sides of the connector. This is advantageous for central relative positioning and support of the connector parts. A central guide element can be arranged as a recess between spring-loaded stop lugs for a one-sided or two-sided center-finding device.

[0029] Alternatively or additionally, the guide device can have one or more decentralized guide elements, in particular recesses. These can be arranged between the centering element and an adjacent retaining element at a free edge of the shell web(s). One or more recesses can also be arranged at a greater distance from the connector center between adjacent retaining elements at a free edge of the shell web.

[0030] In these various configurations, it is advantageous if one or more guide elements of the bridge are each designed as a laterally projecting side projection and extend into one of the aforementioned recesses. Furthermore, one or more guide elements of the bridge can be supported on a lower edge of a recess and rest thereon to fulfill the aforementioned support function of the guide device. This is particularly advantageous if the locking device only has a stop function that prevents the connector parts from lifting off one another transversely to the aforementioned longitudinal axis. Other structural and functional configurations of guide elements of the bridge are also possible.

[0031] The locking device and the respective cooperating locking elements can be designed and arranged differently in the manner mentioned above. One locking element of the plug-in shell can, for example, be designed as a latching opening on a shell web. Another locking element of the plug-in shell can, for example, be designed and function as a stop on a shell web.

[0032] The locking opening enables a positive, locking interaction with a locking element on the bridge. This can also serve a guiding and supporting function. The locking opening can be positioned at a distance below the guide element(s) or recesses on the free edge of the shell web and at a distance above the shell base. The inserted bridge can thus be distanced from the shell base and supported against the locking opening.

[0033] A locking element of the bridge can be designed as a lateral locking projection that projects transversely from the bridge and engages positively into the associated locking opening on a shell web. There are various options for the design of the locking projection. A design as a locking lug that is diagonal and angled in the direction of the roof is particularly advantageous. This locking lug shape can cause the locking lug to slide along the shell web when the connector parts are plugged together, with bridge deformation and subsequent snapping of the locking lug into the locking opening. In the locking opening, the locking lug can rest with its underside on a lower edge of the locking opening. Its upper side can rest against an upper edge of the locking opening or be closely adjacent. This can prevent the bridge from lifting off against the plugging direction.

[0034] The locking opening and the associated lateral locking projection can vary in shape and be coordinated with each other. The locking opening can, for example, have a circular, oval, or prismatic cross-sectional shape, possibly with rounded corners. The lateral locking projection can, for example, be designed as a locking pin protruding laterally from the bridge. The locking pin can, for example, have a cylindrical or cuboid shape with side walls aligned parallel to each other and to the shell base. The underside can be angled to facilitate sliding.

[0035] The aforementioned designs and functions of the locking lug and the locking pin are also possible with other structural designs of a locking projection.

[0036] A wedge-shaped outer contour of a lateral bridge web that widens toward the bridge roof is also advantageous. The outer contour can be adapted to a shell web that slopes outward, allowing the bridge web with the wedge-shaped outer contour and the shell web to lie flush against each other. This is beneficial for the stability of the connector and the plug connection.

[0037] In another embodiment of the locking device as a stop connection, a locking element of the plug-in shell can be designed as a stop on a shell web that protrudes laterally into the shell cavity. The stop can be formed, in particular, by a correspondingly protruding web section of a shell web that is angled several times and subdivided into several web sections. The claimed design and arrangement of the web sections is advantageous for accommodating lateral or width tolerances and height tolerances. The shell web in question can be resilient to accommodate the tolerance in a controlled manner and without adverse or undesirable deformations.

[0038] In a stop connection, a locking element of the bridge can be designed as a laterally projecting stop protrusion and preferably located at the lower edge of one or both bridge webs. The preferably wedge-shaped stop protrusion can also yield resiliently when the connector parts are mated together and then positively engage behind the said stop on the shell web. The stop protrusion can also have a support foot on its underside, which allows the bridge to be supported on the shell base. Alternatively or additionally, the aforementioned support function of the guide device can be used.

[0039] The bridge can have a bulging and preferably rounded roof recess on the end face of the bridge roof, viewed in the longitudinal direction. It can also include a roof slope sloping down to the roof edge in this area. This is advantageous for absorbing and aligning any deformations on the hollow profile wall adjacent to the bridge roof, particularly a profiled roof, when attaching a hollow profile. Such deformations can occur, for example, when separating a hollow profile from a profile section. The alignment function of the roof recess and / or roof slope can bring the relevant profiled roof area into the desired position and ensure a tight connection of the profile end faces at the joint.

[0040] The bridge can have a flat bridge roof on the outside. In another embodiment, one or more roof projections, possibly arranged axially, can be arranged on the bridge roof in the longitudinal direction and on one or both edge sides. These projections can engage with hollow roof webs of a hollow profile. They can prevent unwanted flow of granulated drying agent and can also have a guiding function. A sealant, e.g. a sealing strip aligned transversely to the longitudinal axis of the plug-in connector, can also be arranged on the bridge roof. The sealant can be located at the joint of the hollow profile(s) in the plug-in connection. The bridge roof itself can be arranged close to the profile roof without contact, or it can rest against the profile roof with little pressure.

[0041] The plug-in shell can have various and plural retaining elements, which are arranged, for example, on the free edge of the shell web(s) and / or on the shell base. For the retaining elements arranged on the free edge of the shell web(s), a rectangular shape in side view is advantageous, particularly for optimal retention in a plug-on hollow profile, in particular a warm-edge hollow profile. The rectangular retaining elements can have parallel upper and lower edges and an upright front edge. The parallel upper and lower edges can extend parallel to the main plane of the shell base.

[0042] The connector parts of the claimed connector can be made of the same or different materials. For the connector, it is advantageous if the bridge is designed as a plastic part and the plug-in shell as a metal part, in particular as a stamped and bent part. The metallic bridge shell offers high mechanical stability combined with a favorable spring effect. Designing the bridge as a plastic part has the advantage of a simple and inexpensive design in terms of both construction and manufacturing technology, with adaptability to the plug-in shell. The plug-in shell can be designed as a standard connector that can also be used for other purposes, in particular as a single connector for hollow profiles.

[0043] The connector parts can be coordinated with one another. Each connector part represents an independent, separately claimable invention. The connector parts can be manufactured and supplied individually or as an assembly. The connector parts can be joined together by the manufacturer of the connector parts or elsewhere, e.g., by an insulating glass manufacturer.

[0044] The hollow profile is preferably designed as a warm-edge hollow profile. It can have a profile body made of plastic and a profile shell made of metal, particularly stainless steel. However, the hollow profile can also have any design other than a pure plastic profile or a pure metal profile, e.g., a drawn or rolled metal profile.

[0045] Further advantageous embodiments of the invention are specified in the subclaims.

[0046] The connector and the plug connection can have the following advantageous configurations. These can be used individually or in any combination with each other and with the claimed configurations.

[0047] Interacting guide elements and interacting locking elements can be arranged on the connector parts at a mutual distance transverse to the longitudinal axis. The interacting guide elements can be arranged in front of the interacting locking elements in the plugging direction.

[0048] The respective cooperating guide elements and the respective cooperating locking elements can be arranged in the region of an axial connector center of the connector.

[0049] The interacting guide elements can be designed to guide and direct the connector parts along the mating direction during mating. In particular, they can prevent mutual slippage in the longitudinal direction of the connector.

[0050] The cooperating guide elements can be designed to hold and preferably position the mated connector parts relative to each other in the direction of the longitudinal axis, preferably with a two-sided stop function. This holding function and, if applicable, positioning function can be effective during mating and in the mating position.

[0051] The guide device, in particular the cooperating guide elements, can be designed to mutually support the assembled connector parts against compressive forces in a direction transverse to the longitudinal axis.

[0052] The interacting guide elements can each have a stop edge and a stop side, which interact for guiding purposes and are each aligned transversely to the shell base. The stop edges and stop sides of the interacting guide elements can be aligned parallel to each other and preferably along the insertion direction.

[0053] The cooperating locking elements can be designed to prevent the mated connector parts from lifting off and detaching in the opposite direction of insertion. The cooperating locking elements can be designed to position and / or support the mated connector parts along and transversely to the longitudinal axis. The cooperating locking elements can be designed to support the bridge in the insertion direction with contact or at a distance from the shell base.

[0054] One or more guide elements and one or more locking elements of the plug-in shell can each be arranged on one or both shell webs. One or more guide elements and one or more locking elements of the bridge can each be arranged on one or both longitudinal sides of the bridge, in particular on the outside of one or both bridge webs.

[0055] The guide element(s) of the bridge may be arranged close to the bridge roof and the locking element(s) of the bridge may be arranged at a distance below the bridge roof.

[0056] Interacting guide elements of the bridge and the plug-in shell can be arranged at the axial connector center and / or at the axially adjacent connector areas on both sides.

[0057] The guide element(s) of the plug-in shell can be arranged on a free edge of the shell web. The locking element(s) of the plug-in shell can be arranged on the shell web at a distance below the free edge of the shell web.

[0058] One or more guide elements of the plug-in shell can each be designed as a recess at the free edge of the shell web with an access opening pointing away from the shell base. One or more recesses on the plug-in shell can have an upright web edge that forms a stop edge and that interacts with a stop side of the associated guide element of the bridge for a stop function. One or more recesses can be arranged between a center finding and an adjacent retaining element at a free edge of the shell web. One or more recesses can be arranged between adjacent retaining elements at a free edge of the shell web. One recess can be arranged at the axial connector center between stop lugs of the center finding.

[0059] One or more guide elements of the bridge can be designed as a laterally protruding side projection and can protrude into a corresponding recess in the plug-in shell when the connector parts are plugged together and in their plug-in position. The one or more guide elements of the bridge can be supported on a lower edge of the recess.

[0060] A locking element of the plug-in shell can be designed as a locking opening on a shell web. The locking opening can be arranged at a distance below the guide element(s) on a free edge of the shell web and at a distance above the shell base.

[0061] A locking element of the bridge can be designed as a lateral locking projection, in particular as a locking lug angled obliquely in the direction of the roof or as a transverse locking pin. A locking projection of the bridge, in particular the locking lug or the locking pin, can be designed to engage positively and preferably resiliently in the associated locking opening when the connector parts are plugged together. A locking projection of the bridge, in particular the locking lug or the locking pin, can be designed to rest with its underside on a lower edge of the locking opening. A locking projection of the bridge, in particular the locking lug or the locking pin, can be arranged on a lower edge, in particular in the corner region, of a lateral bridge web.

[0062] A lateral bridge web may have a wedge-shaped outer contour in the central area, widening toward the bridge roof. This widening outer contour may be adapted to a shell web that slopes outward.

[0063] A locking element of the plug-in shell can be designed as a stop on the shell web that projects laterally into the shell cavity. The shell web can have a multiply angled cross-sectional shape divided into several web sections, with one web section forming a stop on the shell web. A web section that projects laterally into the shell cavity can form a stop on the shell web.

[0064] A first web section adjoining the edge of the shell base can have a laterally outwardly bulging shape. A second web section adjoining this section can have a shape that protrudes laterally into the shell cavity. Any web section adjoining this section can have an upright extension directed transversely to the shell base.

[0065] A locking element of the bridge can be designed as a laterally projecting stop protrusion. The stop protrusion can be designed to positively and preferably resiliently engage behind a stop on the shell web when the connector parts are plugged together. The stop protrusion can have an upper stop side and a wedge-shaped sliding side that widens toward the bridge roof.

[0072] The invention relates to a multi-part plug connector (1), its connector parts (2, 3) and a plug connection (8) as well as a plug-in method.

[0073] The multi-part connector (1) is intended for a hollow profile (11) of a spacer (10) or a spacer frame of an insulating glazing unit (9). It comprises two or more connector parts (2, 3) adapted to one another. The plug connection (8) consists of the multi-part connector (1) and one or more attached hollow profiles (11).

[0074] Figure 19shows a partially broken-off side view of insulating glazing (9) comprising two or more panes and a spacer (10) arranged between them and enclosing the interior of the pane, said spacer having at least one plug-in connection (8). The plate-shaped panes are designed, for example, as glass panes. The parallel panes lie flat on both sides of the spacer (10), enclose the interior of the pane, and are fastened to the spacer (10), for example by gluing. The spacer (10) has, for example, a closed frame shape, which can have a rectangular, triangular, or other shape. The spacer or spacer frame (10) is formed by at least one hollow profile (11). The hollow profile (11) contains a preferably granulated desiccant, which is connected to a gas in the interior of the pane by perforations in the profile base (61). The desiccant is also located in the multi-part, hollow plug-in connector (1).

[0075] In the embodiment shown, the spacer (10) is formed by a single hollow profile (11) that is bent at the frame corners. The two ends of the hollow profile (11) preferably meet at a straight profile area at a joint (12). Located at this point are the plug connection (8) and the multi-part plug connector (1) inserted into both hollow profile ends. Alternatively, the frame-shaped spacer (10) can be formed by several individual hollow profiles (11) connected at an angle, e.g., straight hollow profiles.

[0076] The connector (1) consists of several, preferably two, pluggable connector parts (2, 3). The connector (1) has a longitudinal axis (4) and a connector center (5) viewed in the longitudinal axis direction. The two connector parts (2, 3) can be plugged together transversely to the longitudinal axis (4) along a plugging direction (65).

[0077] A first connector part (2) is designed as a plug-in shell, which has, for example, a straight shape and extension. The plug-in shell has a U-shaped cross-section at least in some regions and comprises a shell base (19) and lateral shell webs (20) extending from the latter on both sides at the longitudinal edges. The plug-in shell further has open axial end faces (38) with a base lip (40) thereon and an axially continuous inner shell cavity (39). The plug-in shell further comprises a plurality of preferably resilient retaining elements (26, 27, 28) for retention in a plugged-on hollow profile (11) and a centering element (33).

[0078] On a free edge (21) of the shell webs (20) and on both connector legs (6, 7) there are resilient retaining elements (26, 27) which are inclined outwards and are arranged one behind the other in the longitudinal direction (4) and each point towards the connector center (5). In side view, the retaining elements (26, 27) are each rectangular in shape with straight upper and lower edges and an upright front edge. The upper and lower edges are aligned parallel to one another and to a main plane of the shell base (19). For example, at least one resilient retaining element (28) is arranged on the shell base (19) and on both connector legs (6, 7). The retaining elements (26, 27, 28) can form thin-walled spring noses. They can be cut out of the respective shell web (20) or the shell base (19).

[0079] A further, in particular second, connector part (3) is designed as a bridge with a U-shaped cross-section and comprises a bridge roof (42) and edge and lateral bridge webs (41) extending from the bridge roof (42), preferably on both sides, as well as an axially continuous bridge cavity (45). The further connector part (3) or the bridge is inserted, with the bridge webs (41) pointing towards the shell base (19), transversely to the longitudinal axis (4) in the insertion direction (65), into the first connector part (2) or the plug-in shell between the shell webs (20) and locked there.

[0080] The connector (1) can be divided into two connector legs (6, 7) that extend from the connector center (5) on either side in different directions along the longitudinal axis (4). In the embodiment shown, the connector (1) is designed as a straight connector in which the legs (6, 7) are aligned and merge into one another.

[0081] The multi-part plug-in connector (1) has a locking device (14) and a separate guide device (13) for the connector parts (2, 3), which is spatially and functionally separate from the locking device. The locking device (14) is formed by two or more locking elements (16, 18) on the connector parts (2, 3), each of which preferably interacts in a form-fitting manner. The guide device (13) is formed by two or more guide elements (15, 17) on the connector parts (2, 3), each of which preferably interacts in a form-fitting manner. The said locking elements (16, 18) and the guide elements (15, 17) are arranged at a spatial distance from one another and are functionally separate from one another. The guide elements (15, 17) are arranged at a distance above the locking elements (16, 18) in a direction transverse to the longitudinal axis (4) and transverse to the shell base. The guide elements (15,17) are arranged in front of the locking elements (16,18) in the plug-in direction (65) and have a guiding function.

[0082] The guide elements (15,17) are in Figure 1 arranged at the connector center (5) and on both sides of the connector center (5) on both legs (6,7) as well as on both long sides of the connector (1).

[0083] In the exemplary embodiments shown, the guide elements (17) of the plug-in shell are arranged on the free edge (21) of the shell webs (20). They are designed as recesses on the free edge (21) and have an access opening pointing away from the shell base (19). The recesses (30) are each arranged between the center finding element and the retaining element (27) following in the direction of the adjacent end face (38). The recess (30) is each arranged as a free space between the front edge of the retaining element (27) and the rear side of the center finding element (33). An associated or cooperating guide element (15) on the bridge (3) can insert into this recess (30) when the connector parts (2, 3) are plugged together.

[0084] The central guide element (17) at the connector center (5) is also designed as an upwardly open recess (35) at the free edge (31) of the respective shell web (20). The recess (35) is located at the centering point (33), which in the illustrated embodiment is formed by two stop lugs (34), each aligned toward the connector center (5) and angled outward.

[0085] The guide elements (15) on the bridge (3) are each designed as a laterally projecting side projection (47, 48). The guide elements (15) are designed and positioned on the bridge (3) in such a way that, when the connector parts (2, 3) are plugged together, they protrude into their associated recess (30, 35). The guide elements (15) of the bridge (3) preferably at least largely fill the recesses (30, 35). They have a corresponding height and lateral projection.

[0086] The recesses (30) on the retaining elements (27) each have an upright and preferably straight stop edge (31) extending transversely to the shell base (19) and in the insertion direction (65) of the connector parts (2, 3). The stop edge (31) is formed by an upright web edge. It is arranged on the legs (6, 7) on the side of the recess (30) facing the connector center (5).

[0087] The associated guide elements (15) or projections (47) on the bridge (3) rest with a stop side (47') against the associated stop edge (31) or are at least directly adjacent to it. The stop side (47') is designed, for example, as a flat end wall on the side of the respective guide element (15) facing the connector center (5). The straight stop side (47') also extends transversely to the shell base (19) and in the plug-in direction (65) of the connector parts (2, 3).

[0088] The interacting guide elements (15, 17) on the two legs (6, 7) form a bilateral stop function for the mated connector parts (2, 3), acting like a clamp in both directions along the longitudinal axis (4). This stop function ensures that the connector parts (2, 3) are precisely aligned and positioned relative to each other when mated together.

[0089] The central guide element (15) or the central projection (48) engages in the central recess (35) between the stop lugs (34) when the connector parts (2,3) are plugged together.

[0090] The guide device (13) can also have a supporting function for the assembled connector parts (2, 3). The recesses (30, 35) on the free edges (21) of the shell webs (20) have a lower edge (32) that preferably extends parallel to a main plane of the shell base (19). The guide elements (15, 17) on the bridge and plug-in shell can be coordinated with one another in such a way that the guide elements (15) or lateral projections (47, 48) rest against the lower edge (32) of the respective recess (30, 35) and are supported there. The lower edge (32) forms a supporting edge. At the central recess (35), the lower edge (32) can have a groove or depression in the center, which is adapted to the contour of the central lateral projection (48) and positively receives it in the stop position. This can create an additional axial guide and stop function.

[0091] How Figures 13 to 15As illustrated in the drawing, the guide elements (15) or side projections (47, 48) are arranged on the outside of the bridge in its upper area. They can be located on a connecting roof (42) and / or on a lateral bridge web (41).

[0092] The guide device (13) serves as a guide for the locking device (14) explained below. When the connector parts (2, 3) are plugged together in the plugging direction (65), the interacting guide elements (15, 17) of the bridge and plug-in shell engage in mutual guiding engagement before the locking device (14) is located and closed. This guide function facilitates the plugging together and mutual positioning of the connector parts (2, 3).

[0093] The cooperating locking elements (16, 18) of the locking device (14) are in the embodiment of Figures 1 to 17 also arranged on the bridge (3), in particular the lateral bridge webs (41), and on the shell webs (20).

[0094] In the first embodiment shown, a locking element (18) of the plug-in shell is designed as a latching opening (36) on a shell web (20). In this case, for example, four latching openings (36) are arranged on both sides and at a distance from the connector center (5) on the legs (6, 7) and the shell webs (20). The latching openings (36) are each designed as a through-opening in the wall of the connector web (20) and are arranged at a distance above the shell base (19). The latching openings (36) have a rectangular shape, for example in side view. The latching openings (36) are arranged at a distance below the guide elements (17) on the free edge (21) of the relevant shell web (20).

[0095] An associated locking element (16) of the bridge is designed as a lateral locking projection (49) which, when the connector parts (2, 3) are in the inserted position, engages positively from the inside into the associated locking opening (36). With appropriately adjusted positioning of the locking projection (49) and the associated locking opening (36), a guiding and supporting function can be provided in addition to the locking function. The guiding function can exist in the longitudinal direction (4) and transversely thereto. A supporting function can be provided against transverse forces directed toward the shell base (19).

[0096] In the embodiment shown by Figures 1 to 17 the respective lateral locking projection (49) is designed as a locking lug (50) which has an oblique shape and is angled towards the bridge roof (42). Figure 4 and 17 illustrate this design and the interaction with the respective locking opening (36).

[0097] The locking projection (49) or the locking lug (50) engages positively, preferably resiliently, in the associated locking opening (36) when the connector parts (2, 3) are plugged together. Due to the oblique bend and the likewise oblique outer wall, the locking lug (50) can slide along the facing shell web (20) when the bridge is inserted. It can elastically deflect due to bridge deformation and can spring back upon reaching the locking opening (36) and engage there with a positive fit. Figure 16 shows this situation.

[0098] In the engagement or immersion position according to Figure 4 and 17The spring nose (50) can rest with its underside (52) on a lower edge of the locking opening (36). The spring nose (50) can rest with its upper side (51) on the upper edge of the locking opening (36). The locking device (40) allows the inserted bridge to be supported on the shell web (20) in a floating manner and at a distance above the shell base (19), thus preventing it from lifting off.

[0099] How Figures 12 to 15 As illustrated in the bridge, the locking projection (49), in particular the latching lug (50), can be arranged on a lower edge of a lateral bridge web (41). The four locking projections (49) or latching lugs (50), for example, can be arranged at the corner regions of the bridge.

[0100] Figure 5 and 13 to 17also illustrate that one or both lateral bridge webs (41) can have a wedge-shaped outer contour (57) that widens towards the bridge roof (42). The outer contour (57) can be located in the middle area of ​​the bridge web(s) (41) between the locking projections (49) or latching lugs (50). The outer contour (57) is adapted, for example, to an outwardly directed inclined position of the associated shell web (20) and can bear against this. In the loaded middle area of ​​the plug-in connector (1), the shell webs (20) can support one another via the said contact surface and the bridge (3). The bridge web area above the latching lugs (50) is designed with parallel walls, which is favorable for the said web deformation during insertion.

[0101] The connector part (3) or the bridge can have a surface on the outside of the bridge roof (42) of essentially any shape, preferably adapted to the contour of the hollow profile (11). In the illustrated embodiment, the outer surface of the bridge roof (42) is largely flat and, in the plug-in position, is aligned parallel to the shell base (19).

[0102] In the illustrated embodiment, one or more roof projections (46) projecting from the surface can be arranged on one or both longitudinal edges of the bridge or bridge roof (42). These projections can be designed, for example, as studs and arranged one behind the other in a straight line along the longitudinal axis (4). In another embodiment, a single, beam-shaped roof projection can be provided instead of a row of studs. The roof projection(s) (46) can also be omitted.

[0103] The connector part (3) or the bridge can have, viewed in the longitudinal direction (4), a bulging and, for example, rounded roof recess (44) on one or both end faces and, if appropriate, a roof slope (43) sloping from the roof surface to the end edge of the roof. The roof slope (43) can extend across the entire bridge width, leaving a gap for the roof recess (44). The roof recess (44) can be arranged centrally and extend only over part of the bridge width.

[0104] Figure 18 shows a plug connection (8) which consists of the above-described multi-part plug connector (1) according to Figures 1 to 17 and a hollow profile (11). The plug connection (8) is also Figures 20 to 23 shown in various frontal views and longitudinal sections.

[0105] The hollow profile (11) has a profile base (61), an opposite profile roof (60) and profile side walls (62) arranged therebetween, which enclose a hollow interior of the hollow profile (11). Figure 19 In the installation position shown in an insulating glazing unit (9), the profile base (61) and the shell base (19) of the plug-in connector (1) face the interior of the pane. The profile roof (60) and the bridge (3) are directed toward the outside of the spacer (10) and the insulating glazing unit (9). In the plug-in connection (8), the shell base (19) rests against the profile base (61) of the hollow profile (11) plugged onto one or both legs (6, 7).

[0106] How Figure 18 and 19As can be seen from the drawings, the hollow profile (11) is designed as a warm-edge hollow profile. It is constructed as a composite body made of plastic and metal. The hollow profile (11) can, for example, comprise a profile body (58) made of plastic with a U-shaped cross-section, which forms the profile base (61) and the profile side walls (62). The hollow profile (11) can further comprise a profile shell (59) which covers the upwardly directed opening of the profile body (58) and forms the profile roof (60). The profile shell (59) can be made of metal, in particular of heat-insulating stainless steel. The profile shell (59) can also encompass the profile body (58) and its side walls on the outside and can, for example, be held on both sides with a lower shell edge in a clip groove on the lower region of the profile body (58).

[0107] One or more roof deformations (63) can be arranged on the profiled roof (60). These can be designed, for example, as a ribbed structure or a corrugated sheet structure. An axial roof web (64) can also be arranged on the longitudinal edges of the profiled roof (60) and, if applicable, the profiled shell (59). This axial roof web is open at the bottom and has a curvature directed upwards or toward the outside of the hollow profile. The roof projections (46) of the inserted connector (1) can be received in the hollow roof web (64).

[0108] When forming the plug-in connection (8) and plugging the hollow profile(s) (11) onto the connector legs (6, 7), the plugged-on hollow profile (11) can be pushed until it reaches the center (33) and until it reaches an opposing stop lug (34). In doing so, the stop lug (34) located in front of the connector center (5) in the plug-on direction is passed over and springs back, with the stop lug (34) located beyond the connector center (5) serving with its front side as a stop for the hollow profile (11). The other hollow profile or hollow profile end is then plugged onto the other connector leg and pushed until it reaches the front stop on the first hollow profile (11). The joint of the hollow profiles or hollow profile ends (11) is located at the connector center (5) and is tightly closed. The plugged-in plug-in connector (1) bridges the joint (12) with both connector parts (2, 3).A granulated desiccant can flow through the shell and bridge cavities (39, 45) and through the connector (1). It is prevented from escaping from the connector (1) and at the joint (12) in the region of the joint (12) by the mated connector parts (2, 3). A sealing agent (66) is applied to the connector (1) according to . Figure 24 can additionally seal the joint (12).

[0109] When the hollow profiles (11) or hollow profile ends are plugged in, the retaining elements (26, 27, 28) directed in the plugging direction and toward the connector center (5) are overrun and spring back. When the plug connection (8) is closed, the spring-loaded retaining elements (26, 27, 28) engage the corresponding hollow profile side wall (62) or profile base (61), preventing unwanted removal of an attached hollow profile and opening of the plug connection (8).

[0110] Figures 9 to 12illustrate, by way of example, a design of the connector part (2) designed as a plug-in shell. The connector part (2) is designed, for example, as a metal part, in particular as a stamped and bent part made of sheet steel. Alternatively, it can be made of plastic or another material.

[0111] The connector part (2) is used for insertion and fixation in the attached hollow profiles (11). It has the aforementioned connector legs (6, 7) and the previously described centering device (33). Outwardly curved web embossments (25) are arranged on the shell webs (20) on both sides of the connector center (5). These web embossments are located on the legs (6, 7). They seal against the adjacent hollow profile side walls (62) and prevent the desiccant from flowing through the connector center (5).

[0112] On the free edges (21) of both shell webs (20), on each leg (6, 7), several, e.g. four, retaining elements (26, 27) of the type described above are arranged axially one behind the other. They all have, for example, the aforementioned rectangular shape. Alternatively, a different shape, e.g. a wedge shape, is possible. The retaining elements (26) closest to the end face (38) are arranged lower and at a shorter distance above the shell base (19) than the retaining elements (27) following in the direction of the connector center (5). The upper and, if applicable, lower edges of these retaining elements (27) are at the same height below one another. The aforementioned design can also be modified.

[0113] The retaining elements (26, 27) are cut free from the shell web (20), for example, by a web cutout (29) and bent diagonally outwards. The web cutout (29) has a greater axial length than the retaining elements (26, 27). This creates a free space in each case. In the case of the retaining elements (27) arranged on both legs (6, 7) adjacent to the connector center (5), the free space forms the aforementioned guide element (17) and the recess (30). The stop edge (31) is designed as an upright web edge of the shell web area following the connector center (5).

[0114] The aforementioned design of the retaining elements (26, 27) and the web cutout (29) has particular advantages for a stamped and bent metal plug-in shell, but is also suitable for a plug-in shell made of plastic or another material. If the plug-in shell is designed as a cast or injection-molded part, e.g., from plastic, the shape can be modified, for example, by molding the retaining elements (26, 27) onto the outside of the solid shell webs (20) and by separately introducing the recess(es) (30) at the free edges (21) of the shell webs (20).

[0115] The locking elements (18) or the locking openings (36) are arranged on both sides at a distance from the connector center (5) and, for example, beyond the web embossings (25).

[0116] The bottom lips (4) are directed obliquely upwards and have a stepped shape. The free lip edges may be slit in the middle, with the edge halves being bent and interlaced vertically.

[0117] Figures 24 and 25 show a variant of the plug connector (1) and its connecting parts (2, 3). In this variant, the bridge (3), for example, has a greater height of its bridge webs (41) than in the previously described embodiment. As a result, the upper side of the bridge roof (42) projects beyond the free edge (21) of the shell webs (20). In addition, for example, the surface of the bridge roof (42) is flat and designed without any roof projections. A sealant (66), for example a sealant bead made of butyl, can be located on the bridge roof (42) at the connector center (5) and aligned transversely to the longitudinal axis (4).

[0118] The guide and locking device (13, 14) can be designed somewhat differently than in the manner described above, wherein the locking openings (36) have, for example, a circular cross-sectional shape. Figure 25 The right half of the image shows the previously described design of the locking projection (49) as an angled locking lug (50). In the left half of the image, a design of the locking projection (49) as a locking pin (50') projecting transversely from the bridge web (41) is indicated by hatching. The locking pin (50') can, for example, have a largely cylindrical shape to match the circular locking opening. It can have a sloping, sliding underside.

[0119] In the first embodiment of Figures 1 to 17 For example, the top side of the bridge roof (42) is located at the level of or below the upper side web edge (21) when the connector parts (2,3) are inserted.

[0120] Figures 26 to 33show another variant of the connector (1). The differences affect both connector parts (2,3).

[0121] The guide device (13) and its interacting guide elements (15, 17) on the connector parts (2, 3) can be designed as in the previously described embodiments. The locking device (14) is designed differently in this variant.

[0122] The locking device (14) has a stop connection that acts counter to the insertion direction (65) and prevents the bridge from being lifted off the plug-in shell. For this purpose, a stop (37) is provided as a locking element (18) on the respective shell webs (20), which interacts with one or more stop protrusions (53) as locking elements (16) on the bridge and its bridge webs (41).

[0123] The plug-in shell has according to Figure 26 , 32 and 33a different cross-sectional shape than in the previous embodiments. The two shell webs (20) each have a multiply angled cross-sectional shape subdivided into a plurality of web sections (22, 23, 24). A first web section (22), which adjoins the longitudinal edge of the shell base (19) at the side, has a shape that bulges outwards laterally. The bulge can be designed as a gentle curve or angular. A second web section (23) adjoins the upper edge of the web section (22), which has a shape that protrudes laterally into the shell cavity (39). A third web section (24) adjoins the second web section (23), which has an upright extension directed transversely to the shell base (19). The retaining elements (26, 27) and the centering element (33) can be arranged on the upright web section (24).The second and re-entrant web section (23) forms the said stop (37), which in the plug-in position is supported by the stop hump (53) according to . Figure 33 is undermined.

[0124] Figure 32 shows the position of the two connector parts (2, 3) prior to insertion in the insertion direction (65). The stop protrusions (53) are arranged at the lower edge of the bridge webs (41). They each have a wedge shape with a sliding side (55) directed diagonally outwards and an upper side (54) projecting transversely to the bridge web (41), which interacts with the stop (37) and forms a stop side. A gap or free space is arranged between the guide element (15) and the upper side (54).

[0125] When the bridge (3) is inserted, the stop bosses (53) slide on the shell webs (20) and, while deforming the bridge webs (41), spring inwards into the shell cavity (39), whereby they spring outwards again after passing over the re-entrant web sections (23) and engage behind the stop (37) formed there with the upper side (54).

[0126] How Figure 33 As illustrated, the stop protrusions (53) can have a support foot (56) on their underside, which, in the inserted position, rests on the shell base (19) and supports the bridge (3). The support foot (56) can also be omitted, in which case the aforementioned support function of the guide device (13) comes into play. The lateral projections (47, 48) can rest against and abut the lower edges (32) of the recesses (30, 35).

[0127] Modifications of the embodiments shown and described are possible in various ways.

[0128] In the exemplary embodiments shown and described, the guide elements (15, 17) and the locking elements (16, 18) are arranged on both shell webs (20) and on both sides of the connector center (5) on both legs (6, 7). This arrangement can be modified. The central guide elements (15, 17) in the form of the central lateral projections (48) and the recesses (35) can be omitted. Furthermore, it is possible to omit one or more guide elements (15, 17) on the legs (6, 7). It is also possible to arrange guide elements (15, 17) only on one leg (6, 7) or on both legs, and in each case only on one side of a shell web (20) and with a mutual diagonal offset across the connector center (5). The locking elements (16, 18) can also be modified in the same or a similar way.In this case, the design features of the previously described embodiments and in particular of the various designs of the locking device (14) as a snap-in connection or as a stop connection can also be interchanged and combined with one another.

[0129] Furthermore, it is possible to interchange the mutual design and assignment of the guide elements (15, 17) and locking elements (16, 18) compared to the previously described embodiments. In this case, for example, lateral projections can be arranged as guide elements (17) on the plug-in shell and associated recesses can be arranged as guide elements (15) on the bridge. In the case of the snap-in connection, for example, locking elements (18) on the plug-in shell can be designed as snap-in projections, snap-in noses or snap-in pins and interact with locking elements (16) in the form of snap-in openings on the bridge. A guide bevel for the resilient deflection of the bridge web when the connector parts (2, 3) are plugged together can be arranged on the upper side of the locking elements (18).

[0130] Otherwise, the features of the above-described embodiments and the modifications mentioned can be combined and interchanged in any way within the scope of the claims. LIST OF REFERENCE SYMBOLS
