Definitions

  • the present invention relates to fuse cartridges intended for the protection of electrical circuits and it relates more particularly to devices of this kind which are equipped with an operating indicator capable of permanently informing about the state of the fuse (s). incorporated.
  • this type of cartridge is generally provided with a signal striker which is held against elastic return means by a conductive wire of very reduced section mounted in parallel with the fuse or elements of the cartridge. This wire is immediately broken in the event of fusion of the fusible element (s), so that the striker, thus released, comes to act against the actuation button of a microswitch connected to the power supply of an alarm circuit. .
  • the rocking lever has two wings oriented perpendicular to one another, while the central part comprised between said wings is profiled to have two bearing surfaces, which are themselves oriented square. It is this central profiled part which is in contact with the actuating button of the microswitch and whose movement under the effect of the release of the striker ensures the control of said button.
  • the invention essentially consists in providing, between the profiled central part or hub of the rocking lever and the button responsible for actuating the microswitch, a mobile arm whose free end is provided with a projection arranged to cooperate with a corresponding tooth provided on the hub of the intermediate lever, which movable arm is articulated at a point sufficiently distant from the button so that the curved trajectory of its free end can be compared to a straight line oriented substantially along the axis of the button, eliminating thus practically any lateral component capable of causing a sliding effect at the level of the contact zone.
  • the reference designates the insulating envelope which carries the two usual connection heads connected to each other on the one hand by the fuse element or elements of the cartridge embedded in the usual siliceous mass, on the other hand by the conductor wire with reduced section which retains the striker 2 against the elastic means associated therewith.
  • this striker 2 advantageously provided with a central boss 2 a , is intended to come to control the actuation button 3 of an alarm micro-switch 4, this control being effected against the means elastic 5 associated with said button.
  • a rocking lever 6 which pivots freely on an axis 7 carried by the insulating support 8 supporting said microswitch 4.
  • This lever 6 comprises two wings 6 a and 6 b oriented at 90 ° relative to each other, the free end of the wing 6 b being located in the axis of the boss 2 a of the striker 2.
  • a movable arm 9 which is carried by an axis or pivot 10 oriented parallel to the axis 7 of the lever 6. It will be observed that this pivot 10 is located at a relatively large distance from the axis of the actuation button 3. Furthermore and as shown in FIG. 2, the end of the arm 9 is provided with a projection 9 a which is turned towards a tooth 6 c provided on the central part or hub of the lever 6.
  • pivot 10 of the arm 9 can be oriented perpendicular to the axis 7 of the lever 6 without modifying the operation of the assembly, provided of course that this pivot 10 is sufficiently distant from the axis of the button 3 to that its tilting under the effect of the striker involves practically no axial displacement of its free end.
