Definitions
- the invention relates to an electromechanical primer, i. a primer with an explosive mixture for selectively electrical or mechanical initiation of the explosive mixture, with an outer metal well, an electrically conductive pole piece, a Zünd Portugalny body of an electrically insulating material with a through hole, on the top of a firing bridge is arranged and with a abutment placed on the explosive mixture, wherein in the bottom of the metal
- Cup is introduced a hole into which the pole piece protrudes and the pole piece is electrically connected to a second pole of the ignition bridge and the first pole of the ignition bridge is electrically coupled to the metal cup.
- ANZDH primer caps
- mechanically triggered and electrically triggered are simple containers which are filled with an explosive mixture and which optionally contain an anvil in the form of an anvil (in some cases
- ANZDH is this counter bearing in the cartridge case). To trigger a striker strikes the floor of the ANZDH and presses it quickly, so that the explosive is crushed between the deformed soil and the anvil and its chemical reaction begins.
- the electromechanical Anzündhütchen invention has approximately the dimensions of classic mechanical primer. This shortening of the height is achieved in that the pole piece is used as an electrical connection element, as in the prior art, but it also serves as an impact surface for a firing pin. This is made possible on the one hand by the fact that a part of the explosive mixture rests on the support surface of the pole piece and the counter bearing to above the
- the anvil has a tip and engages at a distance the inner circumferential surface of the through hole in Zündmaschineniharmonic Sciences the tip of the thrust bearing. Therefore, the ZündGermanmaschineni- body claimed no additional height, because he does not increase the distance abutment to the support surface.
- the pole piece is disc-shaped of two mutually offset in height arranged planes, wherein the first plane forms the support surface for the explosive mixture and the second level, the tip of the thrust bearing in the
- the pole piece is thus extremely flat without restricting the function. Since the first level projects into the hole in the bottom of the metal cup, the used height of the pole piece is the thickness of the second level.
- the anvil is an anvil and the tip is a funnel-shaped anvil tip.
- Anvils are sufficiently low in deformation and are well suited as an abutment.
- a metal inner sleeve is advantageously used in the metal cup, which presses the ZündGermanmaschinenyes emotions on the contact surface of the pole piece and electrically couples the first pole of the ignition bridge with the metal wells.
- the inner sleeve is angled at its end facing the Zündmaschinenily Arts end by 90 °, so that a flat surface is formed, which presses on the contact surface of the pole piece.
- the anvil preferably ends with the inner sleeve and is advantageously designed to be three-flighted.
- the anvil is advantageously formed with outlet openings for the ignition gases.
- the underside and the through hole of Zündmaschinenunities are metallized and are electrically connected to each other and is arranged on the edge of the top of a metallic edge contact, which is electrically connected to the first pole of the ignition bridge and is the second pole of the Ignition bridge connected to the metallization of the through hole.
- Zündmaschinenyes emotionss are known per se.
- FIG. 1 shows a sectional view of an inventive electromechanical firing cap and FIG. 2 shows a plan view of the firing bridge carrier body 5 according to FIG. 1.
- the primer (ANZDH) is designed so that the user has free choice as to how he intends to initiate the ANZDH - each ANZDH also offers the possibility of electrical or mechanical initiation.
- a metal cup 1 is used. At the bottom there is an insulation 2 and a pole piece 3 made of metal, which projects into a hole 4 in the bottom of the well 1. Pole piece 3 and metal cups 1 form the two electrical contacts for the electrical initiation.
- the pole piece 3 simultaneously forms the impact surface for a firing pin (not shown here) in the mechanical initiation.
- a Zündmaschinenyes 5 which is a thin ring of an electrically insulating material on which an ohmic resistance is applied as ignition bridge 9 exists (see below).
- a metallic inner sleeve 6 holds on the one hand the insulation 2, the pole piece 3 and the Zündmaschinennic 5 at the bottom of the metal cup 1 and on the other hand, the inner sleeve 6 makes electrical contact between the metal well 1 and the top of Zündmaschinenyes 5.
- the inner sleeve 6 has a relatively large hole in the bottom and has contact with the Zünd stipulatennic 5 only at its upper edge.
- the interior of the inner sleeve 6 is filled with an explosive mixture 7.
- an abutment 8 here an anvil, placed, which closes with the inner sleeve 6 and looks a little beyond.
- the anvil 8 is shown here as anvil, can also be replaced by a corresponding abutment similar shape in the cartridge case.
- An important design feature is the elongated shape of the anvil 8, which ensures a small distance between the tip 15 of the thrust bearing 8 and the pole piece 3. This small distance is for a reliable mechanical
- an ohmic resistance is applied as ignition bridge 9, preferably as a narrow film of conductive material, which produces electrical contact between outer part 12d of the upper side of ignition bridge carrier body 5 and inner part 12c with through hole 13 , This can be done at
- An essential feature of the invention is that at least part of the explosive mixture 7 rests on a support surface 14 of the polar body 3. This ensures that during the mechanical initiation, the explosive mixture 7 is squeezed between the support surface 14 and the tip 15 of the anvil 8, thereby initiating it.
- the anvil 8, here the anvil is usually used in dreierieliger execution (but there are also other versions conceivable), which does not appear symmetrical in section in Figure 1, since one of the openings on the left was captured by the section and right one of the wings ,
- the background image shows a parabolic line that represents one of the exit openings 17 between the wings. Through these exit openings 17 between the wings of the anvil the igniting gases can escape upwards and reach the cartridge in a propellant powder and ignite this.
