Definitions

  • the invention relates to a motor vehicle-technical component carrier for electrical / electronic components, for example for combination with a lock housing or as part of a lock housing of a motor vehicle door lock, with an electrically insulating support element and a conductor path structure of individual metallic conductor paths that can be connected to the support element, wherein the respective conductor track has at least one component clip element for plug connection with an associated metallic clip holder on the component.
  • Component carriers for electrical / electronic components are generally known and are described by way of example in DE 100 07 263 A1. This is generally about an arrangement for fastening conductor track levels on a mounting plate.
  • the associated conductor track structure is mostly a so-called standing grid, that is to say a structure made up of individual conductor tracks that are typically produced from a metal plate or metal foil by a punching process.
  • the known arrangement is used in particular in a so-called central electrical system and is used in automobiles to connect different conductor strands.
  • the mounting plate or the carrier element has a relief-like structured surface with recesses. The recesses are intended to accommodate individual conduction bands.
  • Motor vehicle applications and an associated component carrier are also the subject of the generic DE 20 2012 105 073 U1.
  • the component carrier there which can be traced back to the applicant, is composed of a conductor track structure of at least two conductor track sub-structures of different material thickness.
  • the individual metallic conductor tracks have upstanding conductor lugs as clip elements, with the help of which the components can be electrically coupled by simply plugging in contacts. That has basically proven its worth.
  • the present invention is based on the technical problem of further developing a motor vehicle component carrier of the structure described above so that the plug-in connection between the component clip element and the associated clip holder is made available simply and quickly and with as little force as possible.
  • a generic motor vehicle component carrier is characterized within the scope of the invention in that the component clip element has at least one conductor strip curvature or is designed as such. Also will Preferably, the procedure is such that the clip holder is designed as a clip loop through which the strip curvature can be penetrated by the conductor track.
  • the invention therefore provides a component carrier for motor vehicles, that is to say a component carrier which is suitable and designed for applications in motor vehicle technology.
  • vehicle-specific requirements are met in this context, for example temperature stability, which enables use in a temperature range of approximately -50 ° C to +80 ° C.
  • component carriers are usually designed to be protected from moisture, dust, etc. ingress.
  • the invention takes account of the specific field of application in that typically low DC voltages of mostly a maximum of 48 V are processed at this point.
  • the current intensities can also be described as rather low and are at most in the low single-digit ampere range.
  • the component clip element is now equipped with the at least one conductor strip curvature or is designed entirely as such.
  • This conductor strip curvature is usually produced by curving a conductor strip.
  • the strip conductor as such can be defined, for example, by punching the strip conductor. As a rule, this is done in such a way that the conductor track in question is punched in the longitudinal direction, for example having one or more slots.
  • This slot or the plurality of slots defines the respective conductor track strip with a length predetermined by the punching process in the longitudinal direction of the conductor track in question.
  • the conductor strip in question is now provided with the desired curvature, for example by means of a deep-drawing process.
  • the curvature usually and in side view has a wavy or arched character.
  • the conductor strip curvature now ensures overall for the fact that the conductor track equipped with it experiences an increase in cross-section in the area of the conductor track strip curvature.
  • This cross-sectional enlargement of the conductor track in the area of the conductor track strip curvature is now used according to the invention in such a way that the conductor track enters the desired plug connection with the clip eyelet when reaching through the clip eye as a clip holder on the component to be contacted. This happens as soon as the cross-sectional enlargement achieved by the curvature of the conductor strip passes or should pass the clip eyelet and the desired mechanical plug-in connection is thereby achieved.
  • This presupposes that the cross section of the clip eyelet is adapted to the cross section or the cross section enlargement of the conductor track in the area of the curvature of the conductor track strip.
  • the design will be such that the largest cross section of the clip eyelet is slightly smaller than the largest cross section of the strip curvature so that the conductor inserted into the clip eyelet is securely held in the clip eyelet as soon as the conductor strip curvature is anchored inside the clip eyelet.
  • an electrical plug connection that is easy to produce can be implemented as a result.
  • the operating forces required for this are low.
  • the conductor track can be combined with the clip eyelet by inserting the conductor track into the relevant clip eyelet in its longitudinal extension.
  • the conductor strip curvature is found a fold of the conductor track and the coupling between the conductor strip curvature on the one hand and the clip eyelet on the other hand takes place in that the component in question with the clip eyelet is simply plugged onto the fold of the conductor track with the conductor strip curvature provided there.
  • the electronic or electrical component is usually at the same time a desired placement on the electrically insulating carrier element.
  • positioning elements can additionally be provided on the relevant component and associated counter-positioning elements on or in the mostly plate-shaped, electrically insulating carrier element. The interaction between the positioning elements and counter-positioning elements also ensures the desired alignment of the component in question in or on the carrier element in the assembled state.
  • the curvature of the conductor strip strip extends in the longitudinal direction and / or transverse direction of the associated conductor track, which in turn extends longitudinally.
  • the cross-sectional enlargement of the conductor track equipped with the conductor track strip curvature can take place both in the longitudinal direction and in the transverse direction in comparison to the associated conductor track.
  • the design is usually made in such a way that the curvature of the strip conductor has a transverse expansion and / or longitudinal expansion predetermined by the curvature in comparison to the longitudinally extending conductor.
  • the design is usually made such that the conductor track strip bulges predominantly run parallel to one another in the longitudinal direction of the associated conductor track.
  • the procedure here can also be such that the plurality of conductor track strip curvatures have and have a respective complementary transverse extent and / or longitudinal extent compared to the longitudinally extending conductor track.
  • Another and particularly advantageous variant of the invention is characterized in that, in addition to the at least one component clip element, the conductor tracks have at least one carrier clip element for plug-in connection with the carrier element.
  • the procedure here is usually such that the carrier clip element interacts with a detent spring on the carrier element. In this way, the conductor track can be combined with the carrier element particularly easily, quickly and intuitively, namely also in the sense of a plug connection comparable to the union between the component and the conductor track.
  • the electrically insulating carrier element is generally a plate-shaped element made of plastic, which is advantageously designed as a plastic injection-molded part.
  • the detent spring for the associated carrier clip element and also the counter-positioning elements interacting with the positioning elements on the component can easily be defined on or on the carrier element in question.
  • This can ultimately be implemented in a joint plastic injection molding process.
  • the conductor track structure can initially be coupled to the electrically insulating carrier element (made of plastic) by means of a plug-in or clip connection.
  • the conductor track structure is formed in several parts and is composed, for example, of two or more conductor track structures.
  • the conductor track structure can first be coupled to the carrier element by the described plug connection, in that the one or more carrier clip elements defined on the respective conductor track interact with the detent springs on the carrier element.
  • the respective carrier clip element may be defined as a fold on the conductor track and engage in an associated recess in the carrier element which is equipped with the detent spring for interaction with the carrier clip element.
  • the component carrier in question is typically encased with a potting compound after it has been fitted with the electrical or electronic components in order to protect it from environmental influences.
  • the conductor track structure is generally designed as a stamped grid, which combines various conductor tracks and enables them to be produced together by a punching process, for example a metal plate or metal foil. Together with the carrier element and the electrical / electronic components, the conductor track structure is largely or entirely closed after it has been fitted with the potting compound and can then be installed, for example, in the lock housing of a motor vehicle door lock.
  • the production of the lock housing which is usually carried out by a plastic injection molding process, finally ensures that the carrier element equipped with the components is completely or partially sealed.
