Definitions

  • the invention relates to a switching arrangement in motor vehicles, with an electromagnetic relay, which contains an electromagnetic coil, a movable contact driven by it and a fixed mating contact, and with a fuse element connected in series therewith.
  • the relays known, for example, from DE-OS 23 38 491 are used to switch ever higher currents.
  • the fuses are usually arranged separately in a relatively voluminous housing.
  • this configuration of the electrical switching arrangements in particular causes contacting problems due to the large number of electrical contacts - connection of the electrical lines from the relays to the fuses, the two contacts of the relays in their receptacles and the further electrical lines connected to this receptacle .
  • the invention has for its object to significantly reduce both the overall volume and the number of required contacts in a switching arrangement consisting of an electromagnetic relay and thus a fuse connected in series.
  • the invention solves this problem in a switching arrangement of the type mentioned at the outset in that one of the two relay contacts is additionally designed as an overcurrent protection device and remains at a distance from the other contact in the event of tripping.
  • the basic idea of the invention is to additionally design one of the two contacts of the relay as an overcurrent protection device. In this way, all connection contacts between relay and fuse are omitted. Due to the irreversible behavior of the relay contact serving as overcurrent protection, the contact separation is maintained regardless of the energized state of the relay coil and also regardless of the length of time that has elapsed since the overcurrent protection was triggered.
  • the safety function can be realized with the help of the movable as well as with the help of the fixed counter contact.
  • the design of the fixed counter contact as an overcurrent protection has the advantage of lower manufacturing costs, since conventional electromagnetic relays with a fixed counter contact without a safety function can also be modified subsequently in the manner according to the invention.
  • Such hot wire elements in particular, but also all other possible configurations of the relay contact serving as overcurrent protection, can be designed such that they can be brought manually into the starting position after the triggering event.
  • conventional separate fuses which usually contain a fuse element as a fuse element, the fuse element does not have to be replaced.
  • the relay 1 shown in FIG. 1 contains a coil 2 and a movable contact 3 driven by it. This sits at the end of a copper part 4, which has a magnetic armature part 5 on a magnetic yoke 6 is articulated.
  • the copper part 4 also provides the electrical connection between a connection contact, not shown, which is electrically connected to the yoke 6, and the contact 3.
  • the contact 3 operates with a - together stationary mating contact 7 which is shown schematically and as an overcurrent protection - - normally be used.
  • FIG. 2 In the upper part of this Fig. The counter contact 7 is shown in normal operation. It sits at the end of a hot wire element 8, which consists of two parallel current conductors 9 and 10 (FIG. 3) and a spring 11 arranged in the center. The conductors 9 and 10 and the spring 11 are clamped in a holding block-12.
  • a hot wire element 8 which consists of two parallel current conductors 9 and 10 (FIG. 3) and a spring 11 arranged in the center. The conductors 9 and 10 and the spring 11 are clamped in a holding block-12.
  • the relay shown in FIGS. 1 to 3 works in the usual way. If the coil 2 is energized, it moves the armature 5 and thus the contact 3 in FIG. 1 downward, so that the contact 3 comes to rest on the mating contact 7. The electrical connection between the one connection contact connected to the yoke 6 and another connection contact, also not shown and connected to the mating contact 7, is thus established. The power line between the mating contact 7 and the connection contact described last takes place via the two parallel electrical conductors 9 and 10.
  • the spring 11 is bent in the direction of the arrow 13 shown with the aid of a suitable tool, for example a pin or the like. It dips under the conductors 9 and 10 and leads them and the counter contact 7 back to the starting position. The overcurrent protection is effective again.
