  • the mounting hole can have both round and polygonal borders. The round shape is due to the insensitivity different angular positions preferred.
  • the tongues have one at their ends and one overall Width that is less than the diameter of the mounting opening. This allows the tongues to pass through easily be pushed through the mounting hole.
  • the Recesses on the flanks of the tongue allow that the tongue lies against the edge of the opening, whereby the correspondingly widened end of the tongue Reaches behind the edge of the fastening opening. This is particularly so possible if the tongues are each one length have, which exceeds the thickness of the other element.
  • the tongues only have to be at an angle of be bent about 90 °. It is not necessary to leave them behind the ' the fastener element away from each other to bend. It is sufficient if the through the opening protruding portions of the tongue approximately parallel to each other extend through the mounting hole. This enables easy connection straight insertion of the mandrel mentioned above.
  • the second element is preferably made of a plastic cold-formable material so that the Formation of the connection without special pretreatment of the element can be done. For example, on heating can be dispensed with.
  • the invention Fastening device is particularly suitable for connection of sheet metal parts with each other.
  • the fastening device can do this be used to connect any elements together, provided they have a flat plate-like section have and the connection made other claims enough.
  • the fastening device is particularly suitable for connecting housing parts to each other, and to connect one housing to another Elements, such as a frame, a carrier or similar.
  • ballasts or other electrical equipment by an inventive Fastening device with a lamp plate, connected to a mounting rail or other elements become. It is sufficient to use the device in question, or alternatively on the element that connects to the device is the free cut to be pointed towards each other Attach tongues, one on each side Have recess or indentation to a counter element to be able to reach behind.
  • Devices prepared in this way can be attached to support elements, such as mounting rails or the like, are attached by positioned them over appropriate openings and by piercing a spike that makes the tongues rectangular bends into the fastening openings, fastened become.
  • a ballast 1 is illustrated in FIG. 1, which is arranged on a mounting rail 2.
  • a fastening device 3 serves a fastening device 3 that both Part of the ballast 1 and part of the mounting rail 2 is.
  • the ballast 1 has a housing 4 which at least one flat plate-like, made of sheet metal Section 5 has. This lies flat a flat and thus also plate-like section 6 of the mounting rail 2.
  • For fastening the ballast 1 on the mounting rail 2 are in the mounting rail 2 and in section 6 one or more fastening openings 7, 8 arranged. Tongues 11, 12 engage in these which are free on section 5 of the housing 4.
  • the section 6 with the fastening opening 7 forms a first element of the fastening device 3.
  • the Section 5 forms a second element with the tongues 11, 12 15 of the fastening device 3.
  • Section 5 has an opening 17, for example in a Punching process is generated.
  • the opening 17 represents the two Tongues 11, 12 free, which are opposite and to extend to each other.
  • the opening 17 is so shaped that each tongue 11, 12 on its two flanks 18, 19 and 21, 22 each have an indentation or recess 23, 24 or 25, 26.
  • the opening 17 double symmetrical, namely both symmetrical to a first line of symmetry 27 as well symmetrical to a line of symmetry 28 that is perpendicular stand on each other and both in the plane of the section 5 lie.
  • the tongues 11, 12 are symmetrical bezügl.
  • the line of symmetry 28 formed as the center line lies between the two tongue ends.
  • the opening 17 comprises two lines symmetrical to the line of symmetry 27 kidney-shaped areas centered along the line of symmetry 28 are connected by a slot.
  • the shape of the opening 17 and the tongues 11, 12 goes in detail from Figure 3.
  • the border follows the recess 21 starting from the end of the tongue Radius R which is slightly smaller than the diameter of the Attachment opening 7 or 8, with the center of curvature M in the area of the tongue end 12a of the opposite one Tongue 12 lies.
  • the border follows the Recess 23 in the area of the end of the tongue 12 a same curvature, the center of curvature M1 in Area of the tongue end 11a of the tongue 11 is.
  • the radius is, for example 1.9 mm while the mounting hole has a diameter of 4.2 mm.
  • the final in straight edges 41, 42 Tongue ends 11a, 12a are at a distance A.
  • each tongue 11, 12 has the smallest width D of 2 mm.
  • the tongues 11, 12 thus point near their respective free tongue end 11a, 12a a divergent Border on. Following this, the boundary shows parallel sections 31, 32, which in turn in curved diverging sections 33, 34 pass over. To this The recesses 21, 22, 23, 24 (or indentations) are educated.
