Definitions

  • the invention relates to an electrical device, in particular a power distributor for a motor vehicle, with a circuit carrier and at least one contact element for supplying power.
  • a power distributor for a motor vehicle in which contacts are provided for power supply, which are connected by means of press-fitting with a stamped grid.
  • the contacts can be formed here as a flat plug or blade contacts.
  • the contacts may be connected to the stamped grid by means of several press-fit zones as proposed in this document, there remains the problem that the press-in zones form relatively small contact areas for the current transfer to the stamped grid, for example compared with the terminal area of a tab.
  • the transition region between the individual contacts and the lead frame is therefore to be regarded as critical especially for the transport of high currents.
  • contact element is connected to a bus bar, which is held by at least one resilient connecting element.
  • the busbar is connected via a plurality of resilient connecting elements with the circuit carrier in order to achieve an optimal power distribution.
  • the bus bar is designed as a simple flat sheet metal strip, to which the contact element is integrally formed and preferably one or more simple tabs forms.
  • the busbar is held by resilient connecting elements, which can be advantageously designed as blade contacts. It is particularly advantageous if the blade contacts, as described in DE 10 2004 006 575 A1, are connected in press-fit with the circuit carrier.
  • both a good mechanical and a particularly good electrical connection of the busbar and connected to the busbar contact element is made with the circuit carrier.
  • the advantage here is that can be used as blade contacts mass-produced and thus cost standard components.
  • the busbar as a simply shaped, flat component is very inexpensive, for example, produced as a stamped part.
  • circuit carrier is of course not limited to stamped grid, but may for example include any type of printed circuit boards or ceramic substrates.
  • FIGURE shows a schematic representation of the structure of an electrical device according to the invention.
  • essential features has been dispensed with a representation of electrical components on the circuit carriers.
  • the electrical device which for example forms a central electrics in a motor vehicle, consists of two circuit carriers (1a, 1b), which are arranged within a housing (2).
  • the circuit carriers (1 a, 1 b) can be embodied here, for example, as printed circuit boards, ceramic substrates or metal stamped parts.
  • connection of the circuit carrier (1 a, 1 b) with each other and the electrical connection of a circuit carrier (1 b) to external connections is carried out exclusively in Einpreßtechnik.
  • press-fit pins (5) and on the other hand blade contacts (6a, 6b) are provided.
  • the press-fit pins (5) are designed as preferably cylindrical metal pins which have an integrally formed press-in zone (7a, 7b) at each of their axial end sections (13a, 13b) which can be pressed into a recess of a circuit carrier (1a, 1b).
  • a first press-in zone (7a) of each press-in pin (5) is pressed into a respective recess of the first circuit carrier (1a).
  • a thickening (8) which each Einpreßconfig (5) above the first press-in zone (7a), comes to rest on the surface of the first circuit substrate (1a) and thus provides the exact press-in depth for the first press-in zone (7a).
  • the press-in zones (7b) at the second end sections (13b) of the press-fit pins (5) are inserted in recesses of the second circuit carrier (1b), whereby the two circuit carriers (1a, 1b) are electrically and mechanically connected to each other. Solder connections between the press-fit pins (5) and the circuit carriers (1 a, 1 b) are generally not required.
  • a spacer (9) made of a non-conductive material is arranged, which by its shape the circuit carriers (1 a, 1 b) defines their exact distance and their correct position relative to each other.
  • the spacer (9) has molded Mais Resultssdome (11) with openings (12a) through which the press-fit pins (5) are guided.
  • the spacer (9) thus also serves for positionally accurate mounting of the press-fit pins (5).
  • the spacer (9) can also serve as an assembly aid, in particular if, as shown in the figure, the openings (12a) of the Kunststoffestsdome (11) in the direction of the second circuit substrate (1 b) taper conically.
  • the funnel-shaped openings (12a) act when placing the spacer (9) on the first circuit carrier (1a) practically as Einfädel Anlagen for the already in the first circuit carrier (1a) inserted Einpreßlinke (5), the orientation perpendicular to the first circuit carrier (1a) first still has relatively large tolerances.
  • blade contacts (6a, 6b, 6c) also in Einpreßtechnik, so about spring eyes, solderless connected to the circuit carriers (1a, 1 b).
  • the blade contacts (6a, 6b, 6c) in breakthroughs (12b) of the spacer (9) are used and fixed in position by a tapered shape of the openings (12b).
  • a plurality of blade contacts (6a, 6b, 6c) are arranged to each other such that in their knife holders (10) a busbar (3a, 3b) can be inserted. The inserted into the knife holders (10)
  • Busbars (3a, 3b) are formed by stamped metal strips. A respective laterally projecting from the sheet metal strip section projects through a housing wall and integrally with the respective busbar (3a, 3b) forms a tab (4a, 4b) as a contact element.
