Definitions
- the invention relates to a device for screwless Fixing elements together.
- Electrical ballasts for gas discharge lamps or other electrical equipment usually have a housing on when using the concerned Equipment, for example in a lamp with another element, e.g. a light sheet, one Carrier rail or the like, is to be connected. Join in Screws, rivets or other known fasteners into consideration. It comes with such fortifications often insist on a secure mechanical fit achieve, at least in some cases additionally still a secure electrical connection between the produce the relevant device housing and the element with which the device housing is to be connected. Also it may be necessary to have safe mechanical and electrical Connections between different housing parts manufacture.
- connection In any case, it depends on the connection Can be manufactured cost-effectively, reliably and at low cost.
- the fastening device also enables Forming a connection between two plate-like Sections that have no on one side and on the opposite lying side only a little protrusion having.
- the bent through the mounting hole The length of tongues can be such that barely beyond the edge of the mounting hole protrude.
- Access is only required to establish the connection required from one side of the fastener.
- the tongues of the second element can be from one side forth through the mounting hole of the other element be pushed through. This is the training of Connections also possible under conditions where no access to one side of the fastener consists.
- connection particularly easy. Suffice it to the elements involved overlay that tongues of the second element via the fastening opening of the first element protrude. With a suitable one, for example on two flanks the tongues are then flattened by the Fastening opening pushed.
- 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.
- the fastening device 3 described so far is used to connect the two elements 14, 15 applied together:
- the Tongues 11, 12 first in a common plane to each other.
- the element 15 is on the element 14 placed so that the tongues 11, 12 approximately stand in the middle above the fastening opening 7.
- a Mandrel 35 used, preferably one in cross section rectangular or oval extension 36 with flattened Flanks 37, 38 has.
- the mandrel 35 is aligned so that the flanks 37, 38 approximately parallel to the preferably straight and parallel to each other Tongue ends 11a, 12a are aligned.
- the mandrel 35 will then in the direction of the arrow illustrated in Figure 4 43 is moved perpendicular to the tongues 11, 12.
- the width of the thorn i.e.
- the distance of the flanks 37, 38 from each other is significantly larger than the distance A ( Figure 3) so that the tongues 11, 12 in the mounting hole 7 can be pivoted or bent.
- the resulting Configuration is illustrated in Figure 5.
- the tongues 11, 12 are angled approximately at right angles and protrude with its ends the fastening opening 7, wherein the tongues 11, 12 in this area approximately parallel to each other are aligned.
- the thickness of the mandrel 35 is included dimensioned so that the ends of the tongues 11, 12 firmly on the Edges of the opening 7 are pressed.
- the tongues 11, 12 are thus plastically deformed and retain after pulling out the shape of the mandrel 35.
- the fastening device 3 is relatively insensitive with regard to the exact determination of the thickness of the first element 14.
- first element 14 For connecting plate-shaped elements 14, 15 or other flat parts, for example Sheet metal, together, is the first element 14 with one Fastening opening 7 and the second element 15 with two corresponding tongues 11, 12 provided, the ends of each are widened.
- the connection is made by inserting the two tongues 11, 12 into the fastening opening 7 are bent into it, with their widened ends reach behind the edge of the fastening opening 7.
