Definitions

  • the invention relates to a plug connector and a plug connection with the features in the preamble of the main claims.
  • Such a connector is from DE 20 2014 104 222 U1 known. It is intended for warm-edge hollow profiles of spacers in insulating glazing and has an essentially U-shaped cross section with a base, peripheral side walls and a center stop, as well as laterally flared retaining elements on the free edge of the side walls.
  • the retaining elements are designed to be flexible, with a wall opening being located below the retaining elements and the retaining elements having a wedge shape which widens towards the middle of the connector.
  • the DE 20 2006 009 491 U1 shows a two-part connector whose parts are clamped together in a form-fitting manner.
  • the upper part has projections which are overlapped and clamped by wedge-shaped retaining elements on the lower part.
  • the claimed connector technology ie the connector and its manufacturing process, as well as the connector, have various advantages.
  • the claimed connector offers a particularly good and secure hold in a hollow profile made of a soft, heat-insulating material, in particular a warm-edge hollow profile. This consists at least partially of plastic.
  • the connector is also suitable for other types of hollow profiles with similar advantages.
  • the spring-loaded retaining elements of the claimed connector which are set out at the side, grip optimally on the side walls of the hollow profile.
  • the flexural softness of the retaining elements is less than in the prior art mentioned at the outset.
  • the claimed retaining elements offer a particularly firm and immediately effective retention when pull-out forces act on the closed connector. A gap formation at the connection point of the hollow profiles can be avoided with a high degree of certainty.
  • the connector can easily be plugged into the two ends of the hollow profile.
  • the laterally flared, resilient retaining elements offer a low insertion resistance, which is favorable for manual or automatic insertion, despite their higher bending strength.
  • they act immediately in the above-mentioned manner in the event of pull-out forces acting in the opposite direction and prevent the ends of the hollow profile from being removed from the connection point.
  • the claimed arrangement and shape of the laterally flared retaining elements is particularly favorable for the aforementioned functions and the plugging effect achieved.
  • the pull-out strength on the one hand and the insertion resistance on the other hand are optimally balanced.
  • the lower edge of the retaining elements is straight and no longer has the undercut and the large opening at the bending point as in the prior art mentioned above.
  • the straight front edge of the retaining elements is aligned parallel to the main plane of the associated side wall, which is preferably set out at an angle.
  • the claimed rectangular shape of the retaining elements is advantageous for the said functions.
  • the retaining elements can have the same rectangular shape as one another. The dimensions can vary.
  • the spring-loaded retaining elements which are slanted outwards, can be deformed when inserted into the hollow profiles and set up a little.
  • the retaining elements can optimally engage with the adjacent lateral profile wall with their front edges. Due to the straight bottom edge and possibly the narrow, straight separating cut, the retaining elements have particularly good resistance to pull-out forces, and their straight front edge grips the profile side wall in a linear and optimal manner.
  • a free space between the front edge or front side of the retaining elements and the wall extension of the retaining element that follows next in the axial or longitudinal direction is favorable for an optimal design of said front edge and for the production of the metal connector designed as a stamped and bent part.
  • the bending point or bending edge of the laterally flared retaining elements can be located directly at the end of the axial separating cut.
  • the groove is also an advantage and prevents deformation of the leading edge when cutting free and bending out.
  • the retaining elements are arranged on both side walls and on each side of the middle of the connector in an axial row or group of preferably four pieces.
  • the number can also be different, in particular larger.
  • a preferably outwardly directed embossing on the side walls has advantages for the strength of the connector and for the sealing effect against the hollow profile in the plugged-in position.
  • the preferably upright embossing extends, if necessary, over the lower, bottom part of the side wall and in some areas also over a laterally flared retaining element. As a result, the strength and sealing effect is also present on the retaining element.
  • the embossing can also be omitted.
  • the retaining elements have the different deployment widths claimed.
  • the clamping effect increases with the insertion depth.
  • the deployment width of the spring-loaded stop lugs for finding the center can be the same as or smaller than the deployment width of the respective nearest retaining element.
  • a different height of the retaining elements above the ground is also advantageous.
  • the first retaining elements in the direction of insertion preferably have a lower height than the subsequent retaining elements. Their height can be the same.
  • the length of the front edge or the bending point of the retaining elements can be the same. In a development, these lengths can vary.
  • the retainers adjacent the connector center may have a shorter leading edge length than the other retainers. This is favorable for the insertion and retention of the connector.
  • the connector has a higher mechanical stability, especially flexural strength in the middle area.
  • the claimed quadruple arrangement of retaining elements on each side wall and on both sides of the middle of the connector is also favorable.
  • the connector claimed has a closed and, in particular, flat bottom. This is advantageous for the above-mentioned plug-in effect and the retaining function of the retaining elements set out at the side at the upper free edge of the side wall.
  • resilient retaining elements can be arranged on the floor. These can be directed outwards. Their length can be shorter than their width, in particular the width at the free end edge.
  • the retaining elements can have a conical shape that widens towards the free front edge.
  • Stabilization on the end faces of the floor tongues is also favorable, in particular in the form of an interlocking of the front edge of the tongue.
  • Locking elements are advantageous for handling the loose connectors, which prevent connectors from being plugged together and jammed. This is particularly advantageous for automated handling and pre-plugging of connectors on the ends of hollow profiles.
  • Finding the center in particular a center stop, is favorable in order to be able to position the ends of the hollow profile plugged onto the connector exactly.
  • the center finder can be arranged on one or both long sides of the connector. With suitable, in particular resilient, stop elements, the ends of the hollow profile can butt tightly against one another at the connection point with their end faces. In this way, the formation of gaps and the emergence of granulate at the connection or joint point can be avoided or at least minimized.
  • the raised exterior bottom areas of the connector are also optimized to avoid or minimize granule leakage.
  • the connector is preferably formed as a stamped and bent part made of metal, in particular made of, for example, electrolytically galvanized sheet steel, or also made of carbon steel, stainless steel or the like.
  • the connector is preferably designed as a straight connector. Alternatively, however, it can also be designed as a corner bracket.

  • the plug connector (1) when plugged in, can thus better absorb bending forces and bending moments that can occur when handling the spacer frame formed by the hollow profile (32).
  • figure 17 shows the design of the retaining elements (6,7,8,9) on the free edge (4) of the side walls (3) in a side view.
  • This design is the same in variants (1,2,3).
  • the retaining elements (6,7,8,9) have in accordance with figure 5 and 6 the said height (h1,h2) and the said opening widths (w6,w7,w8,w9).
  • the length of the upstanding leading edges (13) of the retaining elements (6,7,8,9) is essentially the same size.
  • the front edge length of the resilient stop lugs (25) of the center finder (24) can also have the same size.
  • the embossing (18) and the locking elements (21) of the first variant are missing. Alternatively, they may be present.
  • Figure 19 to 22 illustrate a fourth variant of the straight connector (1) in a side view and a folded top view of Figure 19 and 20 .
  • figure 21 shows a broken and enlarged representation of the detail XXI of figure 19 .
  • figure 22 is a perspective view of the connector (1).
  • the base (2) has two resilient retaining elements (37) of the type described above on both sides of the connector center (22).
  • the retaining elements (38) are slightly longer than in the second variant.
  • the base (2) has an outwardly directed elevation (39). It runs the length of the connector (1) and is located in its central area. It forms an outwardly protruding, rectangular base on the floor (2), which springs back again at the edges.
  • the bottom lugs (37) are arranged on the elevation (39).
  • the lateral retaining elements (6,7,8,9) on the free edge (4) of the side walls (3) have in principle the same rectangular shape as in the first three variants.
  • One difference is the length of the upstanding front edges (13).
  • the retaining elements (9) closest to the connector center (22) each have a smaller leading edge length (19). (13) as the front edge lengths (18,17,15) of the retaining elements (8,7,6) following in the direction of the end face (26).
  • the upper edges (12) of the retaining elements (7,8,9) are located accordingly figure 6 each at the same height (h2).
  • the shortened front edge length (19) causes the side wall (3) on the retaining element (9) to have a greater web height from the base (2) to the lower edge (11) or to the separating cut (14) than in the other retaining elements (6,7, 8) has.
  • the connector (1) is stiffened in the area near the center of the connector (22) due to the greater web height. Due to the shortened front edge length (19) and the correspondingly shorter bending point (10), the retaining element (9) is more flexible than the other retaining elements (6,7,8).
  • the length of the front edge (19) is essentially the same as the length of the front edge of the resilient stop lugs (25) on the center location (24).
  • figure 20 illustrates another modification of the fourth variant.
  • the lateral deployment width (w9) of the lateral retaining elements (9) closest to the center of the connector and the deployment width (wm) of the resilient stop lugs (25) can be the same.
  • the deployment width (wm) of the stop lugs (25) can also be smaller than the deployment width (w9).
  • the other opening widths (w6,w7,w8) are sized according to the first variant and figure 5 graded. For the sake of clarity, they are not shown in the fourth variant.
  • the embossing (18) and the locking elements (21) of the first variant are missing in the fourth variant. Alternatively, they may be present.
  • Figure 23 to 25 illustrate a fifth variant of the connector.
  • figure 24 shows a bottom view.
  • figure 23 show a perspective bottom view of the connector (1) and figure 25 a top perspective view of the open cavity.
  • the connector (1) again has a central elevation (39) on the base (2), which forms a base that protrudes outwards from the base (2) and has a substantially rectangular contour. Furthermore, a retaining element (37) and a further elevation in the form of a transverse bar (42) are arranged on the floor (2) on both sides of the connector center (22).
  • the bolt (42) is adjacent to the end face (26) in each case, with the retaining element (37) being located between the bolt (42) and the central elevation (39).
  • the central elevation (39) and the bars (42) can have a depression or recess in the middle.
  • a central row of perforations on the profile base (35) can be accommodated here.
  • the free end edge of the retaining elements (37) can also have such a recess.
  • the embossing (18) and the locking elements (21) of the first variant are missing in the fifth variant. Alternatively, they may be present.
  • the design of the outer surface of the connector base (2) and the inner surface of the profile base (35) can be adapted to one another.
  • the one shown in the other variants adapted, in particular complementary, contouring with peaks and valleys may be present.
  • the number of retaining elements (6,7,8,9) on the connector legs or in the row arrangements on the side walls (3) on both sides of the connector center (22) is also variable.
  • the ratios between the projection widths (w6,w7,w8,w9) and the heights (h1,h2) can also be variable.
  • the plug connection (31) and the hollow profile (32) can also be modified. It can have a different cross-sectional shape and a different material, for example a light metal alloy, steel, stainless steel or the like. It can be produced, for example, as an extruded profile or rolled profile.
