Definitions

  • the invention relates to a gas pressure switch for an ignition and safety device of an ammunition according to the features indicated in the preamble of claim 1.
  • Munitions Ignition and Safety Devices require two physically independent release mechanisms to enable firing circuits.
  • a spin-stabilized projectile for example, the launch acceleration and the projectile spin are used for this purpose.
  • plain tube ammunition for example, 120 mm HE ammunition, however, a spin-dependent release mechanism can not be used.
  • a gas pressure switch for an ignition and security device of an ammunition is from the FR 2 070 544 A known.
  • the gas pressure switch has a shear-off locking pin, which holds a switching piston until it reaches a defined gas pressure in the rest position and shears when reaching the defined gas pressure, whereby the control piston is free and can be moved into its contact position.
  • Same principle is the FR 1 417 132 A removable.
  • the invention is based essentially on the idea to perform the gas pressure switch as an assembly that is designed as a "switching element" once and preferably has the form of a screw which is obliquely screwed from the back into the projectile tail of a corresponding ammunition.
  • the gas pressure switch comprises a displaceable in the direction of the longitudinal axis of the switch switch piston, which is secured in its rest position by a perpendicular to the longitudinal axis of the switch arranged locking pin against unintentional displacement.
  • This locking pin is designed and arranged such that the control piston can not be damaged or moved in case of transport loads occurring and rough handling of the ammunition.
  • the locking pin is preferably sealed on the side facing the charge space by a membrane of a plastic material which is welded to the housing of the gas pressure switch.
  • the membrane presses against the head side of the control piston. As soon as the gas pressure has reached a predetermined value, the locking pin shears off and the switching piston is displaced axially into a sealing seat. During this displacement, the switching piston closes with its lower end two contacts, which forward a signal for ignition release. The plastically deformable membrane also causes the switching piston is held in its contact position, so that the contacts then remain securely closed.
  • the gas pressure switch according to the invention represents a crucial securing element for the firing and safety system of a projectile.
  • the gas pressure switch Before the single switching operation, the gas pressure switch is safely electrically opened until a predetermined pressure (for example 345 bar) is reached. The switching function takes place only when this defined pressure is exceeded. Within about 15 milliseconds after this pressurization, the switch is then closed and remains closed until the detonation of the explosive charge without bouncing. When the gas pressure switch is stored, it remains securely in its open position even after 15 years and meets all functional requirements.
  • Fig.1 illustrates the installation of a gas pressure switch 1 according to the invention in the rear-side region of a smooth-tube projectile, preferably HE projectile 114, wherein the gas pressure switch 1 has the shape of a hexagonal screw.
  • This hex screw 1 is screwed through a thread 14 in a bore of the bullet tail 17 and the screw receptacle sealed by a sealing ring 22.
  • the propellant charge of the projectile 114 is located in a manner known per se in a propellant charge shell 18. Since the projectile shown here is a wing-stabilized projectile, hinged tail wings 19 are arranged on the projectile tail 17.
  • the gas pressure switch 1 ( Fig.2 and 3 ) comprises a housing 100 made of stainless steel, which is designed in its outer shape like a hexagon screw. Inside the housing 100, a cylindrical bore 2 is arranged, which is designed as a conical countersinking 3 towards the upper end and with respect to a guided in the bore 2 control piston 6, which has a corresponding conical surface 3 'in the region of the countersink 3, with a sealing seat forms the sealing surfaces 3 and 3 '. As Figure 4 can be seen, between the sealing surfaces 3 and 3 'additionally an annular damping element 101 made of a plastic material (eg tin or lead) may be arranged.
  • a plastic material eg tin or lead
  • the housing 100 of the gas pressure switch 1 is provided on the outside with a fine thread 14 in the lower area, with the aid of which the gas pressure switch 1 is screwed into the projectile 114 and by means of the metallic sealing ring 22 (FIGS. Fig.1 ) is sealed.
  • the switching piston 6 is surrounded on the upper side by a hat-shaped, plastically deformable and welded to the switch housing 100 hat-shaped membrane 8 and is connected on its underside with a contact device 60 which consists essentially of a pin-shaped element 11, which is a ceramic insert with gold-plated contact surfaces 10 acts.
  • the pin-shaped element 11, which is arranged in an electrically insulated manner on the switching piston 6, is fastened in the region 13 by means of a retaining ring 12 (which is welded to the switching piston 6, for example, by means of laser light).
  • the gas pressure switch 1 may be a provided with the gas pressure switch ammunition body in a corresponding weapon and the control piston 6 in Fig.2 take shown rest position.
  • the pin-shaped element 11 of the contact device 60 is pressed between the two housing-fixed contact pins 5 and electrically connects them together, so that a signal for ignition release to the corresponding (not shown) device is forwarded.
  • the gold-plated contact points of arranged on the control piston 6 ceramic insert 11 and the contact pins 5 guarantee a perfect transfer function of the signal.
  • the membrane 8 Since the membrane 8 is plastically deformed by the gas pressure, it remains in the "everted” state, so that it the switching piston 6 in the lower closed position ( FIG. 3 ) positively fixed and the gas pressure switch 1 remains securely closed.
  • the gas pressure switch 1 according to the invention is gas-tight, if it is pressurized with pressures up to 6,500 bar up to 15 milliseconds. It has proved to be useful if not only the carrier 4 in the region 15, but also the metallic membrane 8 are welded to the housing 100 in the region 16.
  • the Figure 5 and 6 show a second embodiment of a gas pressure switch according to the invention, which is substantially in the Fig.2 and 3 illustrated gas pressure switch differs in that the designated 60 'contact device is not made of a ceramic insert with metallized contact surfaces, but of a metallic contact pin 102 which is connected to a plunger 102'.
  • the plunger 102 ' is held by an in the switching piston 6 holding device 103 made of an insulating material, preferably glass.
  • the switching pin 102 has a diameter and a shape that are selected such that it is in the contact position of the switching piston 6 (FIG. Figure 6 ) in the contact pins 5 "clawed".
  • FIG. 7 and 8th illustrated gas pressure switch differs from that in the Fig.2 and 3 illustrated gas pressure switch substantially by the designated 60 "contact device.
  • the switching piston 6 in its displacement from its rest position ( Figure 7 ) in his contact position ( Figure 8 ) causes a displacement of the contact device 60 "via a plan formed bottom side 105.
  • the contact device 60 "consists of a printed circuit board arrangement comprising four printed circuit boards 106-109 which adjoin one another axially, wherein the first printed circuit board 106 facing the housing-fixed contact pins 5 is intended to effect a centering of the contact pins 5.
  • the second printed circuit board 107 adjoining the first printed circuit board 106 is provided with bores 110 which are arranged above the contact pins 5 and in the rest position of the switching piston 6 (FIG. Figure 7 ) have a relation to the diameter of the contact pins 5 smaller diameter.
  • the second circuit board 107 is followed by a third circuit board 108, which is provided with two sleeve-shaped metallic receptacles 104, which are electrically conductively connected to one another via a copper coating 115.
  • the position of the two receptacles 104 in the third circuit board 108 is selected such that upon displacement of the control piston 6 from its rest to its contact position, the two housing-fixed contact pins 5 are pressed into one of the two sleeve-shaped receptacles 104.
  • a fourth circuit board 109 connects to the upper side, which abuts against the end face 105 of the control piston 6 and on the end face 112 of the third printed circuit board 108, to a movement of the circuit board assembly 60 "in the rest position of the control piston 6 (FIG. Figure 7 ) to prevent.
  • the locking pin 7 When this gas pressure switch is acted upon by a defined gas pressure, the locking pin 7 in turn shears off and the actuating piston 6 pushes down the entire printed circuit board arrangement 60 "via the fourth printed circuit board 109.
  • the contact pins 5 are pressed through the bores 110 of the second printed circuit board 107 and the sleeve-shaped receivers 104 of the third printed circuit board 108 slide over the contact pins 5 so that the gas pressure switch is closed, since the individual printed circuit boards 106-109 are insulated from the housing 100 of the gas pressure switch, between the elements of the printed circuit board assembly 60 "and the housing 100 no electrically conductive connection.
  • the housing-fixed contacts not only rigid, but also be resiliently connected to the housing 100 of the gas pressure switch.
