Definitions

  • the invention relates to an electrical impulse generator, in particular for igniting the propellant or explosive charge in a projectile, in which on movement of an armature by means of an energy store a permanent-magnet circuit is opened and an electrical impulse is produced in an induction coil, and which has an actuating member in the form of a cap engaged over the front end of the housing of the electrical impulse generator.
  • An example of such a generator is found in British patent specification No. 913,896.
  • the present invention concerns a further improvement to an electrical impulse generator of that form in which, by simplification of the construction, easier and thus more economic manufacture is made possible together with greater reliability of operation.
  • An electrical impulse generator is characterised by the fact that the energy store is arranged within the cap-like actuating member and acts by way of a plunger on the armature, which consists, in a known manner, of a cylindrical piston.
  • This construction allows the generator to be assembled from turned and moulded parts which are comparatively simple and cheap to produce, thus rendering manufacture particularly economic.
  • means stop, pins or similar
  • the actuating member ensures the discharge of the energy store and thus the opening of the permanent magnet circuit by mechanical means. An electrical impulse is even produced with certainty, therefore, if the energy store should fail, as is quite possible.
  • the housing 1 of the electrical pulse generator consists substantially of a tube into which a thread is cut at both ends in order to fix the individual components of the electrical impulse generator.
  • an annular permanent magnet 2 Inside the housing 1 is arranged an annular permanent magnet 2, with its pole surface in contact with soft iron pole plates 3 and 4.
  • Inside the annular magnet 2 is situated an induction coil 5 wound on a former 6 made of non-magnetic material.
  • the upper pole plate 3 has a tubular extension 3a which projects into the former 6 for about half the length of the latter.
  • an armature 7 in the form of a cylindrical piston is arranged so that it is longitudinally displacea ble and fits with its end face against the annular surface of the extension 311 of the pole plate 3 forming a surface 21.
  • the lower pole plate 4 has a tubular extension 4a which projects into the space formed by the distance piece 10 and serves to guide the armature 7.
  • the housing 1 is closed, at its upper end, by a caplike actuating member 11 which consists of a pressure plate 11a, which is guided on the housing 1 by means of a tubular extension 11b of the plate. Movement of member 11 which is described later is helped by two circlips 12 fitted externally on the housing 1. A further circlip 13 is positioned on the lower end of the tubular section 11b and prevents the cap being lifted off the housing. A recess 14 is provided on the housing 1 to enable this circlip to be fitted.
  • a plunger 15 made of non-magnetic material, and guided for movement by the extension 3a of the pole plate 3.
  • the plunger 15 rests on the armature 7.
  • the plunger carries a spring disc 16 between which and the pressure plate 11a is arranged an energy store in the form of a spiral spring 17.
  • a further spiral spring 18 serving as a return spring is compressed between the annular disc 8 and the pressure plate 11a.
  • the return spring 18 also guides the actuating member 11 back into its rest position. In this way, electrical impulses of constant strength are produced in quick succession.
  • a buffer cap 20 made of resilient material and supported against a buffer spring 19 is provided in the space provided by the distance piece 10. The armature which is accelerating downwards after pulling away from the gap surface 21 is thereby brought resiliently to rest.
  • the buffer spring 19 and buffer cap 20 are covered over by a plastic tube 22 which separates them from the surrounding space 23 which contains the leads to and from the induction coil and is also filled with an insulating and sealing mass.
  • a buffer disc 24 is provided which is held by the annular disc 8.
  • a further spring 25 initiates and ensures the return of the spring disc 16 with plunger 15.
  • the spring 25 is supported against the upper pole plate 3 and is dimensioned so that its pre-loading is equal to or slightly less than that of the energy store spring 17. This also ensures that the plunger, in the rest position, fits on the armature 7 without loading it by means of the pre-loading of the energy store spring 17.
  • pin 26 does not normally meet the spring disc when the electrical impulse generator is actuated as described previously.
  • the compression spring 17 acting as an energy store is for this purpose so dimensioned that the travel of the spring until the holding force of the magnet is [reached is less than the distance between the pin 26 and the spring disc 16.
  • An electrical impulse generator comprising in combination a housing containing a normally-closed magnetic circuit, an induction coil located within the magnetic circuit, a movable armature forming part of said magnetic circuit, an actuating cap fitted over said housing and movable relatively to said armature, an energy store located in the actuating cap and operable on movement of said actuating cap and an actuating plunger linking said energy store to said armature whereby initial movement of the actuating cap first stores energy in said energy store until the force existing between the actuating cap and the anmature is equal to the magnetic force between the armature and the magnetic circuit when further movement of the actuating cap separates the armature from the magnetic circuit, the energy stored in said energy store serving to accelerate the armature away from the magnetic circuit, and a return device for the actuating cap located within the latte-r.
