Definitions

  • the invention relates to an inductive circuit element with a toroidal core and a composite of U-shaped bracket winding material.
  • the invention relates to a method for mounting a circuit element with a toroidal core and a composite of U-shaped bracket winding.
  • inductive circuit elements such as transformers or chokes to realize the current-carrying windings by using bow-shaped (U-shaped) wire elements, which arch over the core cross-section and are inserted into the printed circuit board individually and parallel to each other, so that they form complete turns together with corresponding traces to which they are soldered.
  • U-shaped wire elements which arch over the core cross-section and are inserted into the printed circuit board individually and parallel to each other, so that they form complete turns together with corresponding traces to which they are soldered.
  • DE3720739 (Meinel ) a substantially O-shaped core, which is held by soldered Windungsbügel, which serve to form two, distributed on both legs windings on the board.
  • U-shaped wire hanger is known from the JP 05090035 A , which will be the closest prior art.
  • the wire bow made of lead wire are formed and arranged around a toroidal core, wherein the ends of the upper bracket are inserted into quiver-shaped forms of the lower bracket and soldered.
  • a mechanical assembly is difficult because the upper and lower bracket must be mounted alternately around the toroidal core.
  • An Indian US Pat. No. 3,638,156 specified method describes the composition of a wound on a ceramic base material.
  • a U-shaped base body is provided with U-shaped conductor tracks, in which a cylindrical core is inserted, wherein the adjacent ends of the conductor tracks are connected diagonally with sheet-metal brackets.
  • Such a ceramic base body is difficult to manufacture for an annular core, which is why the solution for toroidal cores is not considered.
  • the invention is therefore based on the object to provide an inductive switching element with a toroidal core and a composite of U-shaped bracket winding material, which is easy to manufacture and has constant electrical-magnetic parameters. Furthermore, a method for easy installation should be specified.
  • this object is achieved with an inductive circuit element of the type mentioned in at the first bracket and second bracket are provided and the first bracket so arranged the second bracket opposite and are directly connected to each other that they enclose the toroidal core as comprehensive turns and wherein the brackets are formed from sheet metal and have at their back a web, with all the first bracket on a first carrier board and all second bracket are mounted on a second carrier board.
  • the circuit element according to the invention has the advantage that the turns are constructed solely of brackets, which can be adapted in their dimension to the thermal loads. Furthermore, it is achieved by a stable mounting on the carrier boards with constant distances between the individual windings that the electrical-magnetic parameters of identical circuit elements compared to conventional designs have lower scattering.
  • a particularly favorable Feld bedring is achieved with the fact that the bracket made of silvered beryllium, copper or bronze. This results in a uniform distribution of the current and the thermal load.
  • the bracket on the leg ends have contact surfaces at which they are soldered together or that the bracket at one leg end a male connector and at the other leg end male plug and the strap are connected plugged. This results in a simple assembly of the Wicklungsguts.
  • first bracket and the second bracket are made identical. As a result, all the stirrups can use the same tools and production steps for the production.
  • the carrier boards are made of a ceramic material, so that the resulting heat can be better dissipated. Another advantage is the low deformation when heating the carrier boards.
  • Assembly is particularly favorable when the second bracket spanning the toroidal core is preassembled on a common second carrier board. This can be done as in the attachment of the first bracket on the first carrier board by soldering or gluing and leads to a uniform distance between the brackets.
  • Fig. 1 shows an inventive switching element with bracket, which are plugged together, with a variant is selected with a winding surrounding the entire ring core.
  • the base used is a carrier board 1 made of ceramic. These are the first bracket 2 with the off Fig. 3 apparent web 10 rotationally symmetrical soldered to the axis of symmetry of the toroidal core 3, wherein the individual solder joints with each other have no electrically conductive connection allowed to. The distance between the individual first bracket 2 is constant.
  • first bracket 2 of the toroidal core 3 is inserted electrically isolated. This is accomplished by isolating the toroidal core 3 prior to insertion with a dielectric material.
  • the toroidal core 3 spanning second bracket 4 connect two juxtaposed first bracket 2 in such a way that complete windings are given.
  • the winding formed from the bracket is interrupted at one point by the absence of a second bracket.
  • the first bracket 6 and 7 to winding ends which can be contacted via printed conductors 8 and 9 on the carrier board 1 with a circuit.
  • Fig. 2 also shows a circuit element according to the invention, in which case the variant of brackets 2 and 4 soldered together is shown. Due to the absence of two second bracket 4, the toroidal core 3 is enclosed by two windings whose winding ends form the first brackets 6 and 7. These can be contacted via the tracks 8 and 9 on the carrier board 1 with a circuit.
  • the in the Fig. 3 to 6 illustrated bracket is the plug-in version made of sheet metal.
  • Fig. 3 shows the U-shape of the bracket, which has a beveled web 10 on the back.
  • the first leg end 11 is designed as a plug female, wherein the leg is slotted in the middle and the resulting two leg segments as off Fig. 6 are clearly spread apart, so that they serve as a clamping receptacle for the second leg end 12.
  • This second leg end 12 is designed as a straight sheet segment with rounded edges.
  • Fig. 5 shows the slight S-shape of the temple. The extent of the bend is dependent on the pitch of the winding and causes the mating plug female and male plug of the brackets to be connected to each other 2 and 4 lie in a common plane.
