Definitions

  • the invention relates to a corner connector for a control cabinet, according to the preamble of claim 1.
  • the individual frame rods are connected to one another at their ends by means of a corner connector, the frame rods each running perpendicular to one another.
  • a cube-shaped profile element has become known with which three or more frame bars can be connected to one another.
  • the cube-shaped profile element is therefore also a corner connector that is complicated to manufacture.
  • a corner connector has become known from DE 199 32 304, which has an elongated base part with fastening projections which can be partially inserted into hollow chambers.
  • the so-called depth and width struts are constructed with the same cross-section, whereas the vertical frame profile has a different cross-sectional shape.
  • This corner connector is not suitable for attaching a hollow profile similar to that of DE 41 32 803 C3 or that of DE 101 54 706.4 (dated November 9, 2001).
  • the object of the invention is to provide a corner connector of the type mentioned, in which the assembly of triangular hollow profiles is considerably simplified.
  • the corner connector is formed in two parts, both parts each having three mutually perpendicular arms; the frame rods are then clamped between the arms of the two parts for assembly.
  • the second part is then connected to the first part by the second part in one or parallel to a plane spanned by two arms from the outside with respect to the control cabinet against the first part and against the Frame rod is pushed; then the two parts are connected to each other by means of a screw which is aligned in the sliding direction of the second part.
  • the frame rods are clamped between the two parts by tightening the screw.
  • a corner connector with three plug-in lugs has indeed become known from EP 1 152 506 B1, over which triangular profile bars are pushed.
  • the fixation takes place with the help of a clamping piece, which fixes the profile bars by means of its clamping legs.
  • the clamping piece is placed from the inside against the corner connector with the plug-in lugs and screwed tight.
  • the clamping piece encompasses two adjacent side faces of the profile bars.
  • FIG. 1 is a plan view of a corner connector according to the invention
  • Fig. 2 is a plan according to arrow direction II and
  • Fig. 3 is a perspective view of the second part for the corner connector.
  • An electrical control cabinet is composed of frame rods 60, 61, 62, these frame rods being connected to one another at the individual corners by means of a corner connector 10, 11.
  • the control cabinet itself is not shown, but only the corner connector 10, 11, together with the frame rods, of which only parts are shown.
  • the frame rods are designed as described in DE 101 54 706.4. For reasons of simplification, however, these triangular frame bars 60, 61, 62 are only drawn schematically without further details. This is how the hypotenuse is drawn, even though it actually has a tub shape. For these further details, reference is made to the aforementioned DE 101 54 706.4.
  • the corner connector is composed of two parts 10 and 11, between which the frame rods 60, 61, 62 are clamped.
  • the first part 10 has three mutually perpendicular legs 12, 13 and 14, also called arms 12, 13 and 14, of which the two legs 12 and 13 lie in a horizontal plane which is directed towards the floor and runs parallel to it or carry the upper control cabinet roof, depending on where parts 10 and 11 are to be arranged.
  • the leg 14 runs parallel to the plane of the drawing, so that a vertical frame rod 61 of the control cabinet can be connected to it.
  • the leg 14 runs perpendicular to the plane of the drawing, which runs parallel to the floor surface.
  • an eyelet 15 projects into the interior of the control cabinet, which, together with a collar 16 formed on the first part 10, forms an anti-twist protection.
  • the fully assembled control cabinet can then stand up on the end face of the collar 16.
  • the collar 16 surrounds an internal thread 17 into which a lifting eye can be screwed when the corner connector is located on the top of the control cabinet.
  • the second part 11, see Fig. 3, is also a tripod with mutually perpendicular legs 18, 19 and 20, briefly also called arms 18, 19 and 20, of which - in the assembled state - the legs 18 and 19 horizontally run; the leg 20 projects perpendicular to the horizontal plane. If the corner connector is located in the floor area, then the leg 20 projects vertically upward, and if the corner connector is arranged in the ceiling area of the control cabinet, then the leg 20 projects vertically downward.
  • the inner contour, that is the contour of the legs 18, 19 and 20, which is directed towards the first part 10, has a trough shape with a central region 21 which runs in the longitudinal direction of the legs 18, 19 and 20, and with on the longitudinal edges of the central region 21 adjoining bevels 22 and 23.
  • the surface thus formed, which is executed for the first part 10, is a trough-shaped surface which forms a convex surface for the first part 10.
  • a pin 26 running parallel to the arm 12 and a collar-like projection 27 running vertically and at a distance from it are formed, which are located approximately in the area in which the three legs 18, 19 and 20 run together; the pin 16 jumps in the opposite direction as the leg 12 and the projection 27 projects in the opposite direction as the arm or leg 13.
  • the projection 27 there is a bore shown in dashed lines, the inside diameter of which is adapted to the outside diameter of the pin 26, so that when a second control cabinet, for example to the right of the control cabinet, to the corner connector shown in FIG. 1 is associated, is set up, the pin 26 of the second cabinet can engage in the bore 28 of the first, whereby a fixation of the two cabinets against each other and an alignment thereof is generated.
  • the leg 14 which runs perpendicular to the plane of the drawing in accordance with FIG. 1, comprises two walls 40 and 41 which run approximately perpendicular to one another, with projecting strips 42, 43 and 44 being provided on the inner side of each wall 40, 41 facing the control cabinet 1 (in FIG. 1, the strips of the wall 40 are identified by reference numbers; identical strips are also located on the corresponding side of the wall 41, these strips having no reference numbers).
  • shoulders 42 and 43 are provided, which extend in the longitudinal direction of the walls 40 and 41 and are located in a plane 47 which extends at an angle of 45 ° to the walls 40 and 41 ,
  • the sections between the steps 45 and 46 and the free longitudinal edges of the walls 40 and 41 together with the plane 47 form a trough shape which is adapted to the trough-shaped contour of the arms 18, 19 and 20 of the second part 11, so that between the first Part 10 and the second part 11, a trough-shaped gap 25 is formed, in which the hypotenuse section of a hollow profile is located after the respective frame rods 60, 61, 62 have been attached, the hypotenuse section having a shape corresponding to the gap.
  • the frame rod 60 which has a triangular shape, is placed over the arm 12, the cathets 63, 64 running parallel to the legs of the arm 12, which the Legs 40, 41 of the arm 14 corresponds.
  • the catheter 65 corresponding to the cathete 63 is visible; the hypotenuse of the frame rod 61 corresponding to the hypotenuse is not visible. Only the hypotenuse 67 is visible from the frame rod 62.
  • the frame rod 60 is pushed onto the arm 12 in the direction of the arrow M1, the frame rod 62 onto the arm 13 according to the arrow direction M2 and frame frame 61 onto arm 14 according to the arrow direction M3.
  • There are stops on the individual arms in FIG. 1 only the stop 68 on the arm 13 with a Reference numeral designates so that the frame rods 60, 61 and 62 are initially fixed immovable relative to the first part 10.
  • the second part 11 shown in FIG. 3 can be attached in the direction of arrow T1, the trough-like outer surfaces of the arms 18 and 19 against the outer surfaces hypotenuses 66 and 67 of the two frame bars 60 and 62; the arm 20, which runs parallel to the arm 14, rests on the outer surface of the hypotenuse of the frame rod 61.
