Definitions

  • the present invention relates to fuse cartridges intended for the protection of electrical circuits and it relates more particularly devices of this kind which are equipped with an indicator of proper functioning to permanently inform about the state of the or incorporated fuses.
  • this type of cartridge is generally equipped with a striker signaling which is held against elastic means of recall by a very small cross-sectional conductor wire mounted in parallel with the fusible element (s) of the cartridge. This thread 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 a microswitch connected to the power supply of a circuit alarm.
  • the tilting lever has two wings oriented perpendicularly to each other, while the central part between said wings is profiled to have two spans, themselves oriented the square. It is this profiled central part which is in contact with the microswitch actuation button 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 part profiled control unit or hub of the tilting lever and the loaded button actuating the microswitch, a movable arm whose end free is provided with a projection arranged to cooperate with a tooth corresponding provided on the hub of the intermediate lever, which arm mobile is articulated at a point far enough from the button that the curved trajectory of its free end can be assimilated to a straight line oriented substantially along the axis of the button, in thus eliminating practically any lateral component liable to cause a sliding effect in the contact area.
  • Fig. 1 is a partial section showing the actuation mechanism of the alarm circuit associated with a next fuse cartridge the invention.
  • Fig. 2 shows on an enlarged scale the arrangement of the contact area between the rocking lever and the movable arm of the following mechanism fig. 1.
  • FIG. 3 and 4 are sections similar to that of FIG. 1 illustrating the mechanism.
  • the reference 1 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 with it.
  • this striker 2 advantageously provided with a central boss 2a , is intended to come to control the actuation button 3 of an alarm micro-switch 4, this control being effected against the elastic means 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 6a and 6b oriented at 90 ° relative to each other, the free end of the wing 6b being located in the axis of the boss 2a 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 9a which is turned towards a tooth 6c provided on the central part or hub of the lever 6.
  • pivot 10 of the arm 9 can be oriented perpendicularly to axis 7 of lever 6 without modifying the operation of the assembly, provided of course that this pivot 10 is sufficiently away from the axis of button 3 so that its tilting under the effect striker practically does not involve any axial displacement of its free end.
