  • the known device has plug pins formed in one piece with the lead frame for receiving a mating connector with sockets.
  • a system for controlling a restraint device of a vehicle in which a control device arranged centrally in the vehicle is connected via a data line to an external ignition circuit arranged in the vicinity of the occupant protection means.
  • the central control unit detects an impact and transmits a coded ignition command to the outsourced ignition circuit, which decodes the incoming messages and, upon detection of an ignition command, transmits the energy provided on site by an energy storage capacitor to an igniter of the restraint device.
  • the object of the present invention is to provide a device with an electrical circuit arrangement for controlling a restraining means which, as a control device arranged spatially at the igniter, permits the connection of a conventional igniter via a mechanical interface with a high degree of contact reliability and at the same time takes up little space.

  • FIG. 1 shows, according to WO96 / 07302, a lead frame 12 with metal strips which serve as conductor tracks 121 for connecting electrical components 11 which are attached to the lead frame 12 - for example soldered, bonded or glued or soldered as an SMD component.
  • the components 11 are designed, for example, as an integrated circuit, as a sensor, as a resistor or as a capacitor.
  • Parts of the lead frame 12 are designed as connector pins 126.
  • the lead frame 12 is extrusion-coated for protection after all components have been mounted on the lead frame 12 and connected to it in an electrically conductive manner.
  • the lead frame 12 is thus surrounded by a watertight plastic housing firmly connected to it. In this housing, for example, a connector pin 126 surrounding Injection molded connector part or holders 111 for components.
  • the conductor tracks 121 can be mechanically connected to one another via injection-molded plastic bridges, as a result of which good insulation between the conductor tracks and mechanical strength of the lead frame 12 is ensured.
  • the unnecessary conductive connections in the lead frame 12 are subsequently punched out.
  • the circuit arrangement 1 can also achieve sufficient mechanical strength according to FIG. 1 simply by fastening the components 11. If the lead frame 12 has large edge regions 13 which extend beyond the actual region of the connection structures, then electromagnetic shielding can also be achieved by bending these edge regions 13. These edge areas 13 can also serve as cooling surfaces.
  • connection means for receiving and electrically contacting a supplied conductor or plug pin are to be provided according to the invention.
  • FIGs 2 and 3 advantageous developments of the invention are shown, in Figure 2 one piece with the

  • the tabs of a crimp sleeve 12211 and an insulating sleeve 12212 of the crimp connection part 1221 which still protrude planarly, are bent over with a suitable tool, so that the crimp connection part 1221 has a shape according to FIG 4 assumes and when the conductor 2 is supplied it is electrically conductively connected to the lead frame 12 and crimped mechanically by the crimp sleeve 12211, and a firm mechanical connection of the cable consisting of conductor 2 and conductor insulation 21 to the lead frame 12 is achieved by the conductor insulation clamped by the insulating sleeve 12212 21 is guaranteed.

  • the spring tongue and in particular the entire bushing 1231 are preferably made of copper beryllium, which has a high degree of rigidity, which leads to a long-lasting, constant spring action.

  • connection means a web formed in one piece with the lead frame is provided proposed on which a conductor is attached by welding or soldering.
  • All connecting means have in common that due to their one-piece design with the lead frame, there is only a single mechanical interface between the lead frame as the circuit carrier and the supplied conductor / plug pin, and not two mechanical interfaces, such as, for example, in the case of a socket that is swung onto the lead frame or a device with one printed circuit board and a plug part, e.g. between conductor and socket and between socket and lead frame or between connector pin and connector pin and between connector pin and printed circuit board.
  • the durability and safety of the electrical contact between the conductor and the circuit is thus significantly improved.
  • only one manufacturing step is required to create the connection, since the connection means is also produced when the lead frame is punched out. Consequently, the circuit arrangement takes up little space due to the use of the lead frame, which is particularly advantageous when the device is arranged in a vehicle.

  • a restraining means such as e.g. an airbag or a belt tensioner in a vehicle (see also FIG. 6).
  • Circuit arrangements are arranged close to the restraining means. They decode and check a coded trigger command delivered by a control unit for occupant protection located centrally in the vehicle.
  • the transmission line which ends with the conductor 2 in the circuit arrangement 1, is preferably a data bus trained so that several restraint devices can be controlled via a single bus line.
