Definitions

  • the invention relates to an electrical circuit arrangement, comprising a circuit board carrying an electrical conductor structure and one or more electrically conductive lead frames connected to the circuit structure of the circuit board.
  • circuit arrangements are used, for example, in motor vehicles to create a so-called central electrical system.
  • the circuit arrangement described above is a hybrid version in which a circuit board carrying conductor tracks is in electrical connection with one or more lead frames.
  • At least one lead frame has solder pins.
  • the electrical connections made in this way between one or more lead frames and the circuit board meet the desired requirements.
  • automated soldered connections can only be made economically on objects that have a certain size or configuration.
  • the board and the lead frame or lead frames are in a layered structure to each other in prior art central electronics.
  • Such central electrical systems have become known, for example, from DE 42 44 046 C2 and DE 197 13 008 C1.
  • the handling of the individual parts is complex; in particular, when assembling on the assembly line, a mechanic with different equipment of the motor vehicle must have different complete central electronics available.
  • the invention is therefore based on the object of developing an electrical circuit arrangement, in particular suitable for forming a central electrical system for a motor vehicle, in such a way that the disadvantages indicated in relation to the prior art are avoided.
  • the at least one lead frame for electrically connecting it to a conductor track of the board has at least one plug contact element and the board has a plug contact element which interacts with the at least one plug contact element of the lead frame.
  • both the at least one lead frame and the circuit board for electrically connecting these two elements to one another each have at least one plug contact element and these plug contact elements are connected to one another by an electrical plug connector element which interacts with these plug contact elements.
  • the at least one lead frame is connected to the circuit board via contact elements which can be engaged in a plug-like manner.
  • both the lead frame and the circuit board each have complementary interacting plug contact elements for this purpose.
  • These plug contact elements can, for example, be plug-shaped plug contact elements, expediently assigned to the lead frame, and socket-like plug contact elements, expediently assigned to the circuit board. Electrical contact between a lead frame and the circuit board is thus achieved by connecting two complementary plug contact elements.
  • a joining is basically not necessary with the subject of this circuit arrangement. The advantages of such a circuit arrangement concern in particular the possibilities of designing the same, since their design is now not limited by factors determined by the joining method.
  • the circuit board and the at least one lead frame can also be arranged essentially in one plane to one another. It is also possible to connect a plurality of circuit boards to one another by means of leadframes, in order in this way, for example, to implement larger circuit arrangements or also circuit arrangements with a complicated structure. It is also conceivable to arrange one or more lead frames, which have an edge in them, in order to arrange two or more boards at an angle to one another in this way. In this embodiment, space can be filled while the boards and, in particular, the slots are accessible.
  • the two elements - lead frame and circuit board - also have plug contact elements. These cannot be directly engaged to bring about the desired electrical connection between the lead frame and the circuit board.
  • An electrical connection between two such contact elements is made by using an electrical connector element.
  • This connector element works together with the plug contact elements of the circuit board and the lead frame.
  • Such a connector element can be a pure connector element.
  • this plug connection element can also be a functional element, for example a fuse or the like. In this way, the circuit board can in principle be contacted by the lead frame without the lead frame having to be connected directly to the circuit board.
  • plug-in contact element used in the context of these explanations includes all elements with which an electrical connection between such elements can be established by means of mechanical points of engagement with one another.
  • this term encompasses both plug-shaped plug-in contact elements in the actual sense of the word, which are plugged together and disconnected several times However, this term also encompasses those configurations in which initially only the one-off creation of an electrical connection is in the foreground.
  • These contact elements are so-called press-in contacts, the plug parts of which are complementarily designed when they are introduced Plastic parts of the socket are deformed while retaining a residual relaxation.
  • a plug contact element of the lead frame is formed by folding an extension from the plane of the lead frame. It is provided that the contour of the plug contact element is already formed by the stamping process. The folding takes place so that a contact of the two elements with one another is possible with a parallel arrangement of the lead frame and blank with respect to their plane.
  • the blade contact connections that are otherwise used to provide the slots can also serve as the plug contact element.
  • a circuit board for contacting a lead frame can have such a knife receiving contact.
  • the knife-like plug contact element of the lead frame which is complementary to this knife receiving contact, is an extension of the lead frame which engages in the knife opening of the knife receiving contact. This extension is also expediently part of the lead frame.
  • circuit arrangement formed from the at least one lead frame and the at least one circuit board can be retrofitted.
  • Fig. 5 a three-dimensional representation of the board with the
  • Figure 1 connected lead frame of Figure 2, inserted into a housing.
  • Part of a central electrical system for a motor vehicle is a circuit board 1 with a conductor track structure located on the underside of the circuit board 1.
  • the circuit board 1 is equipped with knife receptacle contacts M which protrude upwards in order to provide slots.
  • the knife receiving contacts M are used for electrical contacting of relays, fuses and other electrical / electronic elements.
  • the board 1 also has press-fit contact sockets. Such press-in contact sockets are described in more detail below in relation to FIG. 3.
  • the press-in contact sockets are used to make electrical contact with the conductor tracks of the circuit board 1.
  • Figure 2 shows a lead frame 2, which consists of an electrically conductive metal.
  • the lead frame 2 is used, among other things, for contacting conductor tracks of the circuit board 1.
  • the lead frame 2 also carries knife receiving contacts M.
  • Some knife receiving contacts M of the circuit board 1 and the lead frame 2 are parallel to one another in the assembled position of the two elements - circuit board 1 and lead frame 2 arranged horizontally, so that certain components can be supported both in knife receiving contacts M of the circuit board 1 and in knife receiving contacts M of the lead frame 2.
  • the lead frame 2 has a plurality of plug-shaped plug contacts S, which in the exemplary embodiment shown are designed as press-in contacts.
  • the plug-shaped plug contacts S are each designed as double plug contacts. Each plug-shaped plug contact S engages in a contact socket arrangement of the circuit board 1 formed from two press-in contact sockets.
  • FIG. 3 shows the contacting provided in the illustrated embodiment between a plug-type plug contact of the lead frame 2 and a contact socket arrangement 3 of the circuit board 1.
  • the plug-shaped plug-in contact S shown in FIG. 3 and in the form of a double plug is a continuation of the lead frame 2 and, in its end region opposite the plane of the lead frame 2 to the board 1, is bent downward by approximately 90 ° (see FIG. 2).
  • Two plug extensions 4, 5 of the plug-shaped plug contact element S of the lead frame 2 are used for the actual contacting of a conductor track L of the circuit board 1.
  • the plug extensions 4, 5 are materially formed by their eye-like design in the transverse direction to the plug direction, so that they are under a certain prestress abutting the inside of the press-in contact bushes 6, 7 forming the contact socket arrangement 3.
  • the press-in contact sockets 6, 7 are electrically conductive on the inside, this material being connected to the conductor track L.
  • the contact between the lead frame 2 and the circuit board 1 can thus be addressed as press-in contact. With a contact, as described in FIG. 3, larger currents can be transmitted to the conductor track L of the circuit board 1.
  • FIG. 4 shows a further possibility of electrically connecting a lead frame 2 'to a circuit board 1'.
  • the circuit board 1 ' has knife receiving contacts serving this connection, into which a knife-like plug contact element formed by an extension 9 of the lead frame 2' is inserted.
  • these contact elements are also plug-in contact elements that can be electrically connected to one another only by merging.
  • the lead frame 2 connected to the circuit board 1 is inserted into a housing 10, as shown in FIG. In Figure 5, only the lower, carrier-like area of the housing 10 is shown.
  • the circuit board 1 has first been inserted onto the carrier-like bottom of the housing 10. Code corners 11, two of which are identified by this reference number in FIG. 5, are used for the correct mounting of the circuit board 1.
  • the circuit board 1 is supported on the underside by the housing 10.
  • the lead frame 2 was inserted into the housing 10. Coding pins 12 arranged on the housing 10 serve the purpose of using the lead frame 2 in the correct position. These pass through corresponding openings in the lead frame 2.
