Definitions

  • the present invention relates to fuse cartridges intended for the protection of electrical circuits and it relates more particularly to those which are equipped with an operating indicator capable of permanently informing as to the state of the incorporated fuse or fuses.
  • the body of cartridges of this type generally comprises an insulating envelope which is closed by lateral connection heads provided with connection knives and which encloses a mass of siliceous material inside which at least one fusible element is embedded connected to the aforementioned heads.
  • a conductor wire of very reduced section which retains, against a spring or other elastic means, a striker mounted in a cavity formed in the envelope, which striker, when released, is capable of acting against the actuation button of a microswitch connected to the power supply of an alarm circuit.
  • microswitches of the bistable type have a larger size and a significantly higher cost than those of the monostable type.
  • their operation usually involves a more pronounced actuation force, which results in associating with the striker a more powerful thrust spring and a conductive retaining wire with a larger section.
  • the present invention mainly intends to remedy, and this by arranging the cartridge so that it is capable of being fitted with a monostable microswitch capable of operating in the manner of a bistable microswitch.
  • the invention essentially consists in interposing between the striker and the actuation button of the microswitch an intermediate lever which, as a result of its cam-shaped profile, is capable of affecting two stable positions and thus conferring at the actuation button the two desired stable positions.
  • the cartridge considered is similar to that which has been described in detail in French patent No. 1,560,404 mentioned above.
  • the space thus defined by the body 1-2 contains a siliceous mass 4 in which is embedded at least one fusible strip 5, the ends of which are made integral with the heads 2.
  • These are also connected to each other by a conductive wire 6 of very reduced section, which runs along the internal wall of the casing 1 and which is shaped to determine a central loop suitable for ensuring the retention, against its spring 7, of a striker 8 slidably mounted in a lateral cavity of said envelope.
  • a striker 8 is associated with a microswitch 9 carried by an insulating support 10 fixed to the body 1-2 by two small lateral brackets 11, which microswitch ensures the control of an electric alarm circuit connected to its terminals 9a .
  • the support 10 is largely hollowed out and supports in its notch a fixed transverse axis 14 on which the lever 13 is mounted for the latter 13.
  • the latter provided with two wings 13a and 13b oriented perpendicularly to one another, is profiled in its central part to present two ranges 13c and 13d, themselves oriented square.
  • the wing 13b is located immediately above the central boss 8a of the usual cap 8b which covers the striker 8, while the part 13c forms a support for the actuation button 12, urged by elastic means 12a incorporated into the microphone -switch 9.
  • the internal mechanism of the microswitch 9 can be absolutely arbitrary, in particular of the bistable type, since it is the intermediate lever or cam 13 which gives the actuation button 12 two perfectly stable positions.
  • lever 13 can be provided sufficiently wide to ensure the actuation of two microswitches 9, mounted side by side on the insulating support 10.
