Definitions

  • the object of the invention is to design the contact spring and its attachment in a relay of the type mentioned at the beginning, that the spring can be easily assembled even in confined spaces and that the desired prestress can be achieved by the shape of the spring itself, together with the overall construction, which makes adjustment after assembly unnecessary.
  • prestressing legs 73 and 83 are also formed on these contact springs 7 and 8, respectively, which are supported on the respective coil flange 22 and 32, respectively. Due to the non-positive Fastening by means of the clamping sleeves 71 and 81 and the biasing legs 73 and 83, both contact springs 7 and 8 are biased towards the center contact element 61. Even with a switching movement of the contact springs, there is no rotation on the connecting pins 9 or 10. Rather, the two legs of the approximately hairpin-shaped contact spring 7 or 8 are pressed together when switching, so that they sit even more firmly on the respective connecting pin 9 or 10. In some cases, however, it may be necessary to attach the contact springs to the connection pins by additional means, such as soldering or welding. However, this has no influence on the pretension, since this pretension is already fixed during assembly by inserting the respective contact spring between the center contact element 61 and the respective coil flange 22 or 32.
