Definitions

the invention relates to a transformer or a Throttle according to the preamble of claim 1 and on a method of manufacturing a transformer or a Throttle.
a transformer or a Throttle Such a transformer or such Chokes are known from EP 0 309 690 B1.
a transformer or a choke the core of which from yoke packages and windings arranged between them load-bearing thigh packages.
On the yoke packages are Clamping plates placed from the outside, parallel over the sides tension rods led to the legs are to be braced. The constructive effort for the mutual determination of the Core components are significant.
Claims 11 and 12 include a method for producing the transformer according to the invention or the throttle according to the invention.
each footplate consists of an S-shaped sheet metal strip, one of which Leg 6.11 or 6.21 with recesses 6.12 or 6.22 for Provide recording of fasteners, not shown is.
the respective other leg 6.13 or 6.23 has recesses 6.14 or 6.24 provided for receiving the tongues serve at the free ends of the welding tabs 5.1 to 5.4. Of these tongues, only the tongues are in the drawing 5.22 to 5.42 can be seen.
the tongues protruding in the base plates are usually standing down over the legs 6.13, 6.23 of the foot plates in front. Become more or thicker to create larger air gaps Air gap inserts used, so the tongues protrude less far through the foot plates or close with them flush. The tongues thus cause a limited adjustment the height of transformers and chokes to each present circumstances.
the welding tabs are mirror-symmetrical for universal use executed. Their yokes are so long that they are in the specified manner with the sheets of the yoke stack and have the foot plates butt welded. There where the thighs the L-shaped welding tabs from the yokes of the welding tabs protrude are the yokes with notches 5.13 to 5.43 provided. The depth of these incisions is of the order of magnitude one or a few mm. The cut edges of the incisions converge in an arc at the bottom of the incisions. The purpose of the incisions is to tear the thighs to avoid when bending.
the manufacture of the transformer according to the invention or Choke according to the invention occurs in several on top of each other following work steps; the transformer or the But throttle does not leave the respective workplace, like it does when using tie rods to set the individual core components is required. Reduce it the manufacturing costs in addition to saving the previously required clamping elements and the assembly costs not irrelevant.
