Definitions

  • the invention relates to a motor vehicle technical electrical component arrangement, with an electrical component, and with a component carrier with conductor tracks for electrical contacting of the component, the component being received in a receptacle of the component carrier without casting compound.
  • Motor vehicle technical electrical component arrangements refer to arrangements of components that are used in and on a motor vehicle. As a result, specific requirements for the intended use must be met. This typically includes not only covering a large temperature range from approx. -60 °C to +100 °C, without any functional impairment of the components being observed.
  • electrical component arrangements usually have to be sealed in a moisture- and dust-tight manner in order to ensure functional reliability over long time scales.
  • so-called component carriers are usually used, on or with the help of which the electrical components are positioned and held.
  • the component carriers are equipped with conductor tracks, with the help of which the components are electrically contacted. In most cases, sealing with potting compound is also provided.
  • the components mentioned here are, by way of example and not by way of limitation, switches or sensors in general, as well as electric motors, LEDs, etc.
  • the conductor tracks can be glued to the component carrier (made of plastic) or embedded in the component carrier.
  • component arrangements are used in connection with electric motor drive units, with the help of which control elements are moved.
  • These can be window lift drives, spindle drives, seat adjustments, etc.
  • automotive-technical electrical component arrangements that are used in connection with motor vehicle locking devices.
  • the component carrier carries, for example, drives for electrically opening or locking the locking device as well as one or more sensors with the help of which the respective functional position of the motor vehicle locking device can be queried.
  • the generic prior art according to DE 10 2014 222 428 A1 is about a component carrier switch assembly.
  • an interface is implemented between a switch and the component carrier.
  • the switch is not cast with the component carrier.
  • a ring seal is provided in connection with the interface in question between the component carrier and the switch.
  • a generic motor vehicle technical electrical component arrangement is characterized in the context of the invention in that a sealing projection closing the receptacle is provided on a cover of the component carrier, the cover sealing with the sealing projection when it is combined with the component carrier in the assembly direction the recording intervenes.
  • the invention is initially based on the knowledge that the attachment of the component to the component carrier requires placement of the component in the receptacle of the component carrier. During this process, the component is not only held mechanically in the holder. At this point, electrical contact is typically made between the component and the one or more conductor tracks.
  • the component in question can be equipped with, for example, plug-in contacts, solder contacts or clamping contacts, which form the desired electrical connection with corresponding mating contacts on the associated conductor track.
  • an attempt will be made at this point to establish a solder-free electrical connection, for example in such a way that the switch is equipped with plug contacts which are plugged onto or into corresponding mating plug contacts at the ends of the associated conductor track.
  • the invention is based on the further finding that the component carrier, together with the one or more components mounted thereon and electrically contacted, is generally covered with the aid of an additional cover to be attached.
  • the component carrier can, for example, be arranged inside a housing or itself represent a component of the housing.
  • the attachment of the cover as a generally further component of the housing ensures that the receptacle in the area of the electrical connections between the component and the associated conductor track is properly closed with the help of the sealing projection on the cover. This is because the sealing projection engages in a sealing manner in the receptacle when the cover and the component carrier are combined in the assembly direction.
  • the sealing projection as a whole ensures that any free areas remaining within the receptacle enclosing the component are closed with the help of the sealing projection.
  • the cover can in principle be removed from the component carrier, so that if necessary and for repair purposes, the component and in particular its electrical connection or contact area with the associated conductor track becomes accessible. This is where the main advantages can be seen.
  • the cover for the component carrier does not necessarily have to cover the entire surface of the component carrier. That is, within the scope of the invention there are also variants such that the cover only partially covers the component carrier, for example Area of the component or several components. Either way, mounting the cover relative to the component carrier in the mounting direction not only ensures the desired coverage of the component carrier, but also ensures that the receptacle with the component placed therein is closed by the sealing projection.
  • the sealing projection is equipped with at least one sealing lip for sealing.
  • the sealing lip can be formed onto the sealing projection.
  • An embodiment has proven to be particularly favorable here, in which the sealing lip is molded onto the sealing projection.
  • the sealing lip for example made of an elastomeric plastic, can therefore be injected directly onto the sealing projection in this way, for example in a two-component injection molding process.
  • the component carrier is usually also a plastic molded part and in particular a plastic injection molded part.
  • the relevant conductor track or a conductor track structure can be surrounded by the plastic, for example by inserting a lead frame into a plastic injection molding tool for producing the component carrier and overmolding it with the plastic of the component carrier.
  • a plastic injection molding tool for producing the component carrier and overmolding it with the plastic of the component carrier.
  • other types of production are also conceivable, for example in such a way that the conductor tracks are glued to the component carrier (also made of plastic) as a conductor track film.
  • the sealing lip can be connected to the sealing projection transversely to the assembly direction.
  • the sealing lip it is also alternatively or additionally possible for the sealing lip to be connected to the sealing projection in the assembly direction.
  • the sealing lip consequently has an extension transversely to the assembly direction, while the second-mentioned case corresponds to the extension of the sealing lip in the assembly direction.
  • the sealing projection is generally designed as a plug-in pin or at least one plug-in pin. It is also possible for two or more spaced-apart plug pins to be used, which in conjunction with the cover ensure the sealing of the receptacle or the remaining free area in the receptacle.
  • the plug-in pin or the two or more plug-in pins can be equipped with a sealing formation.
  • the sealing formation can be a flexible area that is provided on the plug pin in question. This flexible area can be defined in a similar way to the sealing lip by, for example, injection molding of elastomeric plastic.
  • the plug-in pin and the receptacle are equipped with corresponding bevels.
  • the bevel on the plug-in pin automatically slides along the corresponding bevel or counter-bevel of the receptacle and thus ensures the desired sealing of the receptacle.
  • a motor vehicle-related electrical component arrangement is made available which has particular advantages in terms of manufacturing and assembly technology. Such advantages are observed in basically all applications of the component arrangement in question.
  • a component arrangement is used in conjunction with an electric motor drive.
  • This electric motor drive can be placed inside a motor vehicle lock housing.
  • the component carrier may coincide with a wall of the associated housing.
  • a design of the component carrier that is separate from the housing is also conceivable.
  • the component in question can be placed in the receptacle of the component carrier, while at the same time the desired electrical Connection to the conductor track or a conductor track structure is made.
  • the free area observed in this way inside the receptacle is then sealed because the cover closing the component carrier engages sealingly in the receptacle with its sealing projection. This is where the main advantages can be seen.

  • the automotive electrical component arrangement with its electrical component or switch 1 is accommodated inside a lock housing 2, 3.
  • the lock housing 2, 3 is a lock housing 2, 3 of a motor vehicle door lock, in which, in addition to the switch 1, there is space for a locking device (not shown) and an operating lever arrangement.
