Definitions

• the invention relates to a method for contacting electrically conductive stamped gratings, wherein at least a first and a second stamped grid are brought into electrical contact with each other at at least one location. Furthermore, the invention relates to an arrangement of at least two electrically conductive stamped gratings.
• Punching grids are known from the prior art. They are used in the areas of an electrical network, in particular in a motor vehicle, in which conductive elements and printed conductors with a high current carrying capacity and a sufficient intrinsic stability are required.
• the basis for producing a stamped grid is a sheet-like starting material, for example a sheet metal, in particular a copper sheet, from which the electrical paths and connections are formed by means of shaping processes, in particular stamping and / or bending. It is known to the person skilled in the art that a punch grid does not have to be understood as a grid in the narrower sense of the word, but rather that even the simplest geometries, such as a strip-shaped conductor track, fall under this term.
• At least one recess with at least one contact zone is formed on a first stamped grid for electrical contacting of electrically conductive stamped grid, and the contact tongue is inserted into the recess such that at least by means of the contact zone an electrical connection between first and second punched grid is produced.
• first and second stamped grid allows that only the contact tongue has to be inserted into the recess for electrical contacting. Since no further machines or tools are required, as would be the case, for example, with spot welding or riveting, the production costs are reduced.
• the method shown offers the advantage that the connection between the stamped bars can be broken down in a simple manner - can be solved trouble-free again.
• the method according to the invention enables a multiple connection and disconnection of the two punched grids by inserting or removing the contact tongue.
• the shape of the contact zone can be manufactured in different shapes depending on the existing requirements.
• the contact zone may be substantially punctiform, linear or planar.
• the contact zone can also be composed of several contact areas, for example opposite sides of the recess.
• the proposed contacting of stamped gratings can be used particularly advantageously in the central electrical system of a motor vehicle.
• punched grids are used to produce electrical connections between printed circuit boards, plugs and interchangeable elements, such as fuses or relays. For details on Gott ⁇ electrics of a motor vehicle is made to DE 100 21 217 C1.
• the contact tongue is angled relative to the first stamped grid, in particular approximately at right angles. This allows a particularly flexible arrangement of the stamped grid to each other, so that can be taken into account special spatial conditions.
• first and second punched grids are positioned approximately parallel to one another prior to insertion of the contact tongue into the recess. This results in a particularly space-saving arrangement of the two stamped grid, in particular in zu ⁇ sammengesteckt state.
• At least one contact nose is formed integrally with the second punched grid.
• the contact nose is formed in particular at the edge of the recess and faces the center of the recess. If now the contact tongue is inserted into the recess, then at least a well-defined contact point results.
• the contact nose bends partially elastic when inserting the contact tongue and exerts a compressive force against the contact tongue.
• Partially elastic is to be understood in the context that the contact nose is deformed both plastically and elastically during insertion, so that a - albeit small - elastic restoring force remains.
• the contact nose securely holds the contact tongue in its seat. The force exerted by the contact nose on the contact tongue force - A -
• the contact tongue lies in a narrowly defined, in particular (almost) punctiform area, so that a sufficient pressure for holding the contact tongue is established. If the contact tongue is pulled out of the recess, for example during disassembly, then the contact nose springs back by a certain amount in the direction of its original position so that the secure contact is ensured even if the contact tongue is inserted again.
• an insertion aid in particular in the form of a material taper, is formed in the front region of the contact tongue.
• Such an insertion aid may be formed, for example in the form of a tip.
• a recess on the third stamped grid is formed such that the contact tongue passes through the recess without contacting the third stamped grid in order to avoid contact with a third stamped grid which is positioned between the first and second stamped grid ,
• a leadframe arrangement with multiple punched grid levels it will not always be necessary for each leadframe to have electrical contact with each other leadframe. Rather, different groups of leadframes may be required, with the leadframes of one group being at a potential which should be different (at least temporarily) from the potential of another group of stamped gratings.
• a stamped grid arrangement could carry a ground potential, while another stamped grid arrangement bears an operating voltage potential.
• a punched grid of a punched grid arrangement is now located between punched grids of another stamped grid arrangement, unwanted contacting by means of the proposed cutout can be avoided in a simple manner.
• This allows a high flexibility in the arrangement of stamped gratings.
• a recess with at least one contact zone is preferably formed on the third stamped grid (ie in addition to the recess present in the second stamped grid) and the contact tongue through the Recesses inserted in the second and third punched grid. This makes it easy to establish a connection between a plurality of lead frames.
• At least the contact zone of the third stamped grid has a contact nose formed integrally with the stamped grid, which is bent in the direction of the second stamped grid upon insertion of the contact nose in such a way that the contact nose contacts the second stamped grid.

• Such a arrangement enables a particularly favorable electrical contacting of two stamped gratings with simultaneous mechanical stability of the connection.
• a third stamped grid is arranged between the first and second stamped grid, which has a recess in which the contact tongue is arranged without an electrical contact.
• the stamped grids (at least at least at certain times) should carry different potentials.
