Definitions

  • the invention relates to a device for shake-proof accommodation of special electrical components and / or electrical circuits, in particular in the form of a second component level in a control unit.
  • a carrier which consists of a lead frame which is encapsulated with plastic.
  • the components are welded to forks, which are part of the lead frame, and the special components are held on the carrier by means of an adhesive bead, which is arranged between the component and the carrier.
  • the carrier itself is screwed to a base of a control unit by means of screws.
  • the invention is accordingly based on the object of making available a device for shaking-resistant accommodation of special electrical components and / or electrical circuits, which ensures that the special components are held securely in the event of various vibration excitations.
  • the inventive concept enables the use of various components, designs and circuits without major changes, and there is also the possibility of realizing the size of a control unit by moving the special components and, if necessary, circuits to a second electrical level.
  • the device according to the invention it is advantageously possible to achieve a high degree of flexibility when changing components, and the use of other components and designs is possible by simply changing the layout.
  • the circuit carrier is preferably applied at least in part over an electrically insulating medium.
  • This insulating medium can consist of an insulating film, advantageously with heat conduction properties. It can be applied to the carrier in individual sections or over the entire surface, in particular by gluing.
  • the carrier may have passages for contact pins that pass through and is accordingly not connected to the circuit carrier in such areas.
  • the circuit carrier is applied to the carrier after the circuit carrier has been fitted, in particular with SMD components. It is preferably provided that the circuit carrier fastened on the carrier can be connected to a control unit via pins or a flexible film or a plug connection.
  • the pins attached to the circuit carrier can preferably be designed as pin strips, SMD pins, stamped and bent parts or pin strips.
  • Pin strip is arranged on a tab of the circuit carrier, which protrudes outward beyond the carrier. This advantageously gives the pins an additional elastic property, what helps to secure the contact connection and to reduce the transmission of vibrational excitations to the circuit carrier.
  • the pin strip can advantageously be pressed into the circuit carrier as a pin strip in order to save a manufacturing step, the pin strip being soldered to a main circuit board.
  • a connection between the circuit carrier and the control device can also take place via the SMD pins, which are soldered to the circuit part, and project downwards over the lateral edges of the carrier for connection to a motherboard. This also advantageously enables good vibration decoupling of the circuit carrier.
  • the circuit carrier has screw openings for the passage of fastening screws which can be screwed into the bottom of a control device.
  • the carrier is preferably made of cast aluminum and thus combines the advantages of high rigidity with those of good heat dissipation.
  • the circuit carrier is applied in an electrically insulated manner via an electrically insulating medium, for example a plastic film. If the carrier alternatively consists of an electrically non-conductive material, the circuit carrier with special components attached to it can be applied directly at least over part of the surface.
