Definitions

  • the present invention relates to an arrangement for the electrical connection of an electronic circuit in a housing, in particular in a hermetically sealed housing, which is in electrical connection with at least one connection element, and a corresponding method.
  • hermetically sealed housings which are currently available in different designs.
  • One embodiment of such a hermetic housing has a base plate, through which connection pins are inserted for the electrical connection of the circuit located inside the housing.
  • the connection pins which are also referred to as connection elements, are used during production in receiving bores of the base plate with a glass blank. By melting the glass at appropriate temperatures and then cooling it creates a dense electrically isolated bond between the pins and the base plate.
  • the pins are electrically connected to the electronic circuit in a known manner, such as by bonding.
  • the base plate with the circuit disposed thereon is closed by a lid, which is sealed under a protective atmosphere with the base plate, whereby a hermetically sealed housing is formed.
  • the pins protruding outward from the base plate are usually round solid wires made of certain materials that are suitable for glass remelting. They are connected outside of the hermetically sealed housing to electrical line elements, such as electrical busbars by means of laser welding or soldering.
  • the electrical busbars connect to peripheral devices such as sensors, actuators, plugs of the vehicle.
  • peripheral devices such as sensors, actuators, plugs of the vehicle.
  • Other cable connections for example in the vehicle wiring harness, have previously been formed by flat ribbon cables (Flexible Flat Cable or FFC).
  • Out EP 820119 is the connection of a ceiling light on a vehicle roof to a device for power supply known.
  • the housing of the ceiling light has on its back outstanding contact pins for connection to the power supply.
  • a first and an attached second line element are contacted with the contact pins.
  • the first line element is a conductor bundle or a flexible circuit with conductor tracks, which is connected to evt. Other electrical devices on the vehicle roof.
  • the second line element comprises power supply cable with attached at the ends eyelets with clamping straps. Before attaching the eyelets to the contact pins for connecting the ceiling light to the power supply, the eyelets are laterally inserted into receiving channels of a connector made of a plastic. By means of the connector, the first line element and the second line element are electrically isolated from each other. An insulation of the first conduit member to the housing is not provided.
  • GB 2341485 describes a method for contacting line elements with contact pins protruding from a housing. Specifically, an alignment element is placed over the connection elements between the housing and the line elements for this purpose. The alignment serves as an alignment aid for the correct positioning of the contact pins to each other. Thus can be welded at right angles to it at the end defined line elements.
  • connection of the ribbon cables takes place in a simple manner, the geometry selected allows a compact design. Furthermore, a protection of the terminal against electrical short circuits and bridges, for example, starting from conductive chips, easy to implement.
  • An arrangement according to the invention for the electrical connection of an electronic circuit in a housing, in particular in a hermetically sealed housing, which is in electrical connection with at least one connection element, has the features of the independent claim 1:
  • the contact portions and / or the connection elements are formed such that the contact portions for forming the electrical connection of the connection elements are penetrable.
  • the contact portions are provided with at least one recess and / or an incision, and / or that the connection elements are provided with a formed for penetrating the contact portions tip and / or cutting edge.
  • connection elements are connected to the corresponding contact sections by welding, preferably laser welding.
  • a further embodiment provides that the contact sections and / or the connection elements are formed such that the electrical connection is formed by a press-in connection in the form of an insulation displacement connection or "speed-groove" connection.

  • the layer applied in the connection section has the function of positioning the pins and thus positioning the line element.
  • the cover has openings that cooperate with the pins.
  • the cover is applied to the terminal portion.
  • the layer in the connection section serves in other functions: Through this layer, a positioning of the cover and at the same time its attachment to the layer is made possible.
  • the line element is a flat cable (Flexible Flat Cable, FFC), a flexible printed circuit board, a stamped grid or a plastic extrusion-coated stamped grid.
  • a ribbon cable can be easily processed for connection to the connection elements advantageous. It is also used for the wiring harness in the vehicle and thus does not form a new component, wherein a stamped grid can be omitted as a conduit element with elaborate processing or preparation. However, a punched grid with or without plastic extrusion is also usable. Flexible printed circuit boards are also used as line elements. Thus, an advantageous versatility is possible.
