Definitions

  • the object of the invention relates to a device for supplying electric power to the subammunition fuses in a carrier projectile, allowing electrical connections to be established between its carrier projectile fuse, acting as a power supply, and the subammunition fuses, making connection between the subammunition fuses by an interface.
  • One of the objectives of subammunition carrier projectiles is to cover an extensive area and avoid having the subammunition items arriving at the target together.
  • the ammunition carries with it an electric or electronic element, for instance the fuse as such, a retarder, and so forth, it will need to be supplied with electric power through connections.
  • an electric or electronic element for instance the fuse as such, a retarder, and so forth, it will need to be supplied with electric power through connections.
  • the projectile has a single power supply and these connections are made with standard commercial elements, the extent of bonding of the subammunition items to each other and to the projectile is enhanced, thereby hindering ejection and expulsion of the subammunition items, whence the possibilities of the same arriving together at the target is greater.
  • the present device to power the subammunition fuses in a carrier projectile is original and differs from existing electrical connection devices or elements, its main advantages being as follows:
  • the carrier projectile fuse is the powersup- ply, during carriage and storage the electrical circuit will be disabled, for no electric power is generated until after firing.
  • this device can withstand powerful acceleration without its power supplying capacity being diminished it can be applied to any kind of subammunition carrier projectile, such as artillery grenades, mortar grenades, rockets and so on.
  • the device for supplying electric power Fig. 1, essentially comprises a distributor 1, common for the whole device and a column 2 and a contact plate 3, for each subammunition 15.
  • the distributor 1 is a printed circuit and works to receive through the leads 5 and distribute to its contactors 6, the electric power received from an outside power supply 4, in our case the carrier projectile fuse.
  • the distributor 1 and the last contact plate 3 are insulated from the decks 7 and 8 through insulating plates 9 and 10.
  • the columns 2 allow interface connection between the printed circuit 1 and the contact plates 3.
  • the column 2 comprises a body 11 and inside there are as many contactors 12 and flexible conductors 13 joined to one another, as each application may require, generally positive supply, negative supply and short-circuit.
  • the contact plate 3 is a printed circuit having contacts 17 on either side, Fig. 2.
  • the subammunition 15 fuse 14 is connected to the contact plate 3 joining the feeder cables 16 to the contacts 17.
  • the distributor 1 and the contact plates 3 are connected by means of the pressure exerted by the flexible conductors 13 on the contactors 12, supported by the distributor 1 contacts 6 and the contact plates 3 contacts 17.
  • both the columns 2 and their contactors 12 and flexible conductors 13 are designed to withstand without collapsing the strains produced by the firing acceleration and to take up the misalignments that may come about between subammunition items 15 in a same column.
  • the device causes no additional bonding that might hinder ejection and expulsion of the subammunition items 15, as a result of such electrical connections.
  • the fuses 14 are communicated to each other and to the distributor 1.
  • the external power supply 4 is set going and the distributor 1 is powered through the feeder cables 5 and distributes the power to its contacts 6.
  • connections between the printed circuit 1 and the contact plates 3 are made only by interface such connections are no hindrance nor a bond for each subammunition 15 and its fuse 14 and contact plate 3 to be sent off from the carrier projectile as easily as they would be if there were no connections.
