Patent number: 8381650Abstract: A safety and arming unit for a fuse includes a firing chain having first and second firing devices defining an intermediate space therebetween and a barrier blocking the intermediate space in a safe position. The firing chain is brought into an armed position by a releasing movement vacating the intermediate space. First and second mutually independent securing devices lock the barrier in the safe position and execute an unlocking action based on two mutually independent physical arming parameters. A compact and very reliable safety and arming unit can be achieved in this way.Type: GrantFiled: November 5, 2008Date of Patent: February 26, 2013Assignee: Junghans Microtec GmbHInventors: Karl Glatthaar, Reiner Hennig, Gerhard Heussler, Karl Kautzsch, Frank Martin Kienzler, Alexander Zinell

Patent number: 8007934Abstract: An activatable battery for an electronic artillery fuse and mortar fuse includes an ampoule filled with an electrolyte, and an activation device for rupturing the ampoule. In order to evaluate the duration of a mechanical impulse acting on the battery, the activation device can be freed by a timing member having an inertia body which is axially and rotatably displaceable and against which a compression spring is operative. A compact structure and reliable installation of the ampoule in the battery is achieved in that the battery has an upper battery portion and a lower battery portion, the activation device is provided in the upper battery portion and the ampoule is disposed immovably in the lower battery portion.Type: GrantFiled: September 20, 2007Date of Patent: August 30, 2011Assignee: Junghans Microtec GmbHInventors: Karl Glatthaar, Herbert Höni, Alexander Zinell

Patent number: 7699003Abstract: A safety and arming unit with a safe separation distance device (14), which acts as a function of a free-flight incident flow and temperature, for the fuze (12) of a projectile (11), which fuze is hermetically sealed from environmental influences, has, as a measurement device for the cooling, as a function of the incident flow, of a conductor through which current passes, in the heating circuit (18) of a resistant heating element (16) which is fitted flat on the fuze casing surface (17), an electronic current measurement apparatus (21) which is connected upstream of an evaluation circuit (22), in order to ram a firing circuit. Two heating elements (16, 16?), which are fed in the same way, are preferably arranged one behind the other in the incident flow direction (15), and, additionally as an environmental temperature sensor, a comparison heating element (16?) which is not influenced by the incident flow (15).Type: GrantFiled: September 20, 2007Date of Patent: April 20, 2010Assignee: Junghans Microtec GmbHInventors: Alexander Zinell, Reiner Hennig, Rolf Kaden

Patent number: 7685941Abstract: A penetration-capable projectile has a casing and a fuze with a fuze housing lower part. An interface area between the casing of the projectile and the fuze housing lower part is formed with a shape and/or strength modification which prevents the fuze housing lower part from being pushed into the casing on impact with a target that is to be penetrated.Type: GrantFiled: April 7, 2008Date of Patent: March 30, 2010Assignees: Junghans Microtec GmbH, Diehl BGT Defence GmbH & Co.

Patent number: 7661364Abstract: A safety and arming unit (11) which is designed in particular for an electrical fuze circuit (27) does not reliably respond just to lateral loads on one side, but responds only to centrifugal forces produced by the spin during free flight, in that two contact pairs (22-23, 22-23) which are connected electrically in parallel with one another via rings (14, 15) and are arranged diametrically opposite one another on a cross-sectional plane of the fuze (12) are both no longer electrically conductively bridged at the same time by the bolt (17) because, just by virtue of the centrifugal force, both bolts (17) are simultaneously moved radially outwards from their short-circuit safety positions in their blind holes (16), which are oriented transversely with respect to the rotation axis (13).Type: GrantFiled: September 20, 2007Date of Patent: February 16, 2010Assignee: Junghans Microtec GmbHInventors: Alexander Zinell, Reiner Hennig, Alfred Boos

Publication number: 20090255431Abstract: A modular miniaturized priming chain has a detonator and a priming booster assembly. The priming booster assembly includes a first priming booster and a second priming booster which can be modularly combined together depending on the respective power requirement at an output of the priming chain, or only the first priming booster is combined with the detonator, which is a miniature detonator.Type: ApplicationFiled: February 12, 2009Publication date: October 15, 2009Applicants: JUNGHANS MICROTEC GMBH, DIEHL BGT DEFENCE GMBH & CO.

Patent number: 7491099Abstract: A pressuretight contact connection for the programming and power supply for fuze electronics is described, which is provided in a housing (10) from which a contact pin (34) projects in an electrically insulated and pressuretight manner in order to make contact with a connecting element (12). The connecting element (12) has a contact surface element (16), which is provided in an insulating housing (14) and has contact fingers (24) in the area of a through-hole (18) which is formed in the insulating housing (14), which contact fingers (24) clasp the contact pin (34) in an interlocking manner when the connecting element (12) and the housing (10) of the fuze electronics are in the mated contact state.Type: GrantFiled: May 11, 2006Date of Patent: February 17, 2009Assignee: Junghans Feinwerktechnik GmbH & Co., KGInventors: Alexander Zinell, Martin Leonhardt, Frank Kienzler, Egon Klaussner

Patent number: 7461596Abstract: A safety and arming unit (10) for a spinning projectile fuze, which has a fuze body (12) and a bearing body (14), which define a spherical cavity (16) between them, in which a spherical rotor (18) is mounted such that it can rotate, in which rotor (18) a detonator (20) is provided. In order to make the safety and arming unit suitable for fuzes in weapon systems with extremely fast munition feed units, the rotor (18) can be surrounded by a rotor locking ring (28) in the safe position, prevents the rotor (18) from rotating through an acceleration ring (30) and a spring element (32) which connects the acceleration ring (30) to the rotor locking ring (28) in an interlocking manner, with the rotor locking ring (28) being formed with a slot (36) in order that it can be spread open by rotation and centrifugal forces into an open space (34).Type: GrantFiled: October 12, 2007Date of Patent: December 9, 2008Assignee: JUNGHANS Microtec GmbHInventors: Alexander Zinell, Frank Kienzler, Martin Leonhardt, Ronald Ketterer, Günter Westphal
