Definitions

  • the invention relates to an induction component, in particular a high-current throttle.
  • Such components contain in a housing a coil whose winding ends are to be connected to solder pads of a circuit board.
  • the tinned winding ends are formed as an SMD soldering surface.
  • JP 2011-159957 A discloses here an induction component according to the preamble of claim 1.
  • the winding ends of the coils wound from round wire are wound around terminal formations ( US 5952907 ).
  • the coil ends of the round wire coils are also wound around terminal contacts ( US 2011/00503783 A1 ).
  • a housing for an induction component, which simultaneously forms the core is also known (US Pat. EP 0026104 A1 ).
  • the coil ends are wound around terminal contacts of a carrier.
  • an induction component in which the coil is wound from flat wire, wherein the flat side of the flat wire runs parallel to the coil axis ( JP 7-3 20961 ).
  • JP 2010219473 and US 2003/0201859 A1 disclose further induction components with a flat coil.
  • the invention is based on the object to provide a particularly suitable for automatic assembly induction component.
  • the invention proposes an induction component with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.
  • the induction component proposed by the invention thus contains a housing, in particular of ferrite material or of pressed substrate powder, in which at least one coil is arranged.
  • the coil is carried by a support member which is also disposed in the housing.
  • the support member includes on the one hand terminal contacts to mechanically and functionally connect the induction member to a circuit board, and on the other hand terminal formations, which are attached to the coil ends of the coil and with which they are connected.
  • the planarity of the terminals thus no longer depends on the shape and nature of the coil ends of the coil and the coil ends of the coil can be reliably and reliably connected to the terminal training.
  • the terminal formations are designed as welding plates with which the coil ends are welded.
  • the carrier element consists of plastic and the connection contacts are injected or pressed into the plastic. This facilitates the production.
  • connection formation for the connection of each winding end is formed integrally with the respective associated connection contact. There are therefore no additional connections between the coil ends and the metal parts required to form or have the connection contacts. These metal parts may be coated on their side forming the terminal contact, depending on the requirements of the case. Connection formations and connection contacts can then be injected in sections into the plastic of the carrier part.
  • the carrier element is fixed immovably in the housing. This can preferably be done by a positive connection between the carrier element and the housing, wherein, optionally, an additional bonding may be provided.
  • the carrier element is centered in the housing through the housing.
  • the housing has a cylindrical spool core and the carrier element is centered with a tubular portion on the spool core.
  • the carrier element has a centering for the coil.
  • This centering makes it possible that the carrier element simultaneously forms an assembly aid for assembly during assembly of the induction component.
  • the centering for the coil is formed as a tubular portion of the carrier element. With the outer periphery of the tubular portion of the coil is centered and with the inner circumference of the tubular portion, the support member is centered on the housing.
  • the housing has a flat bottom and a plane parallel to this extending flat top, wherein the end faces may be formed on the short end faces as flat surfaces.
  • the bottom is that side of the housing to understand, which is opposite to the mounting on a circuit board of the circuit board.
  • the coil of the induction component proposed by the invention is wound from flat wire whose flat side is perpendicular to the coil axes.
  • the support member may have a third surface which is constructed as a contact surface, so that it can be attached to the circuit board with the same technology with which the terminals are connected to the circuit board.
  • this third pad does not make contact because it is not conductively connected to a coil.
  • the third surface or other surfaces may also be made of plastic, for example at the end of a plastic pin or plastic pin, which is then pressed or hot-spliced with the circuit board.
  • This solution applies primarily to an induction component with only one coil.
  • the carrier element also serves for centering and holding the coil.
  • the carrier element may have a central annular portion or tubular portion, which serves both for centering the carrier element relative to the housing and for centering the carrier element relative to the coil or vice versa.
  • This central ring portion may be plate-shaped, so lie substantially in a plane. Both its outer edge and its inner edge can serve for centering with respect to the housing.
  • the coil can be attached to the inner edge of the ring portion individual perpendicular to the plane of the ring portion extending fingers.
  • the central ring portion may also be cylindrical.
  • the cylindrical shape of the ring section can serve both for fixing the carrier element and for centering the coil.
  • the support element may have at least one leg that extends to the bottom of the housing of the induction component and is provided there with a foot.
  • the underside of the foot is preferably located approximately in the plane of the underside of the housing.
  • connection formations for connecting the winding ends of the coil project at right angles out of a surface of the carrier element in the direction of the coil axis, preferably out of the upper side of the foot of the carrier element.
  • a surface for connection between the coil ends and the connection formation is available, which allows for the assembly and the preparation of the compound free access, for example for a welded joint.
  • the connection formation may for example also have a U-shaped bent sheet, wherein the coil end is pushed between the legs of the sheet and then connected thereto.
  • Fig. 1 shows in a perspective view obliquely from above an inventive induction component according to a first embodiment.
  • the induction component has a lower housing half 1a and an upper housing half 1b, which are formed identical to one another.
  • a coil 7 is arranged within the housing.
  • the coil is wound from flat material and has opposite the actual winding of the coil at right angles bent coil ends 8, 9 up.
  • the winding ends 8, 9 are disposed within each U-shaped terminal formations 31 and welded to these terminal formations 31.
  • the terminal formations are arranged on a support part 32, which also holds the coil 7, as will be explained below.
  • the presentation of the Fig. 2 shows the induction component of Fig. 1 in an exploded view.
  • the coil 7 with the coil ends 8, 9 is placed on the support member 32 and held on a ring portion 16 of the support member 32 by means of three webs 26 which are arranged on the circumference of a central hole of the ring member 16 and follow the curvature of the hole.
  • the webs 26 thereby define portions of a cylindrical surface, which is tuned to the inner diameter of the coil 7 and the coil 7 thereby centered on the support member 32.

These bent sheets are injected during the production of the support member 32 made of plastic in this. This can ensure that the connection contacts 33 lie in a common plane. It is thus easily possible to connect the induction component by means of the connection contacts 33 with solder pads 34 on a circuit board 35.
  • the circuit board 35 has a third solder pad 36.
  • This solder pad 36 is provided with the underside of a leg 37 of the support member 32, see Fig. 3 to be connected, for example, to be soldered.
  • the solder pad 36 is preferably insulated and inoperative in electrical terms. Since the leg 37 is injected in the production of the support member 32 and contains at its bottom, for example, an injected, metallic surface, it can be ensured in the manufacture of the support member 32 that the terminal contacts 33 and the underside of the leg 37 are exactly in a plane and The induction component according to the invention can thus be reliably soldered to the circuit board 35.
