Definitions

  • the invention relates to a coil arrangement with a winding body on which the coil winding is attached and a method for contacting this on a carrier body.
  • Coils are used in a large number of measuring mechanisms to generate a magnetic field utilized. This requires that the coil winding be continuous Current signals or current pulses are supplied. For this purpose the winding ends of the coil with live electrical leads connected. In most cases, one end of the winding comes with the electrical one Lead soldered or glued.
  • the coil winding is wound on a winding body.
  • the wire ends are soldered to separate contact pins. This The contact pin is soldered to the electrical leads. For every Coil arrangement therefore requires several operations.
  • a coil arrangement is known, with a winding body, on which the coil winding is attached, with the winding body two contact feet are arranged and one end on each contact foot the coil winding is attached.
  • the contact feet are designed such that they are connected to a circuit board in push-through assembly can.
  • the object of the invention is to provide a coil arrangement specify the generic features of claim 1, which also at surface mounting leads to a safe and durable contact. This object is achieved in that at least one contact foot is fork-shaped is designed.
  • the fork-shaped contact foot advantageously has one on the coil former facing recess.
  • the recess enables the accumulation of even more contact paste during the contacting process, which is due to the wide contact area for an even safer and more durable contact leads.
  • the contact foot advantageously has a recess or elevation Take up the winding end. This recess is between the winding body and the recess arranged. Below the fork-shaped contact foot a guide for the winding of the respective winding end is provided.
  • each winding end has at least one turn looped a contact foot.
  • a multilayer wrap around each contact foot leads to a reliable fastening of the respective winding end on the contact foot.
  • Such a cleverly designed winding body with two molded contact feet carries the coil winding and ensures a secure fixation of the wire ends on the contact feet.
  • the wire ends themselves are made with the electrical ones Supply lines directly connected.
  • the contact foot parallel or perpendicular to the coil winding at one end of the winding body is arranged.
  • the distances between the two contact feet make sense chosen so that they correspond to the distance of the interconnects of the circuit board.
  • the coil arrangement according to the invention enables simple contacting on a support body provided with electrical leads, in which the windings of one winding end of the coil winding fastened to the contact foot are arranged close enough to the supply line and by means of a suitable connection method, e.g. B. with the help of an electrically conductive Contact paste can be contacted with electrical leads.
  • a mechanical contact between the winding end of the coil winding and the supply line is desirable but not absolutely necessary.
  • a small gap between the winding and the lead can be soldered with Capillary action or welding can be easily overcome with contact pressure.
  • the contacting can be done using methods such. B. thermocompression welding, Soldering with a solder paste, melting with infrared radiation, Laser or thermode or conductive adhesive.
  • the carrier body is a printed circuit board, an automatic reflow soldering or melting process for contacting.
  • the circuit board is preferred a flexible conductor foil or a composite conductor system.
  • the coil arrangement consists of a winding body 24 with a coil winding 22.
  • This winding body 24 has two electrically insulating contact feet 25a and 25b on a plane at one end of the bobbin 24 are attached parallel to the winding 22.
  • the contact feet 25a and 25b have an identical structure. They are so fork-shaped that they have a recess in the opposite direction to the winding body 24 34a, 34b, which is open to the interconnect of the circuit board 27.
  • the contact feet 25a and 25b each have a recess 32a and 32b for fixing the turns 28a and 30a on the respective contact foot.
  • a first end 28 of the coil winding 22 is produced multiple times wrapped around the first contact foot 25a so that the turns 28a after the Assembly on the circuit board touch the interconnect 26.
  • the winding body 24 After the first contact foot 25a has been wrapped around, the winding body 24 also becomes the coil winding 22 provided. Then the second contact foot 25b in the same way as the first contact foot 25a with the second Coil end 30 wrapped.
  • the contact feet 25a and 25b on the printed circuit board 27 attached and are electrically connected to the interconnect 26, 26a of the printed circuit board 27 connected.
  • the turns 28a touch the interconnect 26 and the Turns 30a the interconnect 26a.
  • the fork-shaped design allows contact paste to accumulate, in the present case solder paste and thus ensures reliable contacting the interconnects with the winding ends.
  • the contacting can also done by conductive gluing.
