Patent number: 6002312Abstract: An electromagnetic relay has a base with a contact arrangement and a rocker armature mounted on the base. Above the base, a magnet system with a coil, a core and two yokes is provided, this system working together with the rocker armature. At least the coil with the core is embedded in the insulating material of a basic body which surrounds the base in box-type fashion with side walls that are integrally formed downwardly, and forms a sealed contact chamber. By means of the basic body surrounding the coil, a high insulation strength of the relay between the coil and the contact system is ensured, as is a high stability of the construction.Type: GrantFiled: September 2, 1998Date of Patent: December 14, 1999Assignee: Siemens AktiengesellschaftInventors: Michael Dittmann, Jens Heinrich, Heinz Stadler

Patent number: 5908568Abstract: A connecting pin of a coil, which has an end section with an end section of a winding wire wound thereon with a plurality of turns, is initially provided with a drop of a fluxless soft solder and then arranged in the vicinity of the points of two opposite electrodes. An arc of a specific strength and duration is struck between the electrodes, so that the soft solder is fused and connects the winding wire to the connecting pin. The result is a fluxless soldering of the winding end in conjunction with low thermal loading of the coil former and of the connecting pin.Type: GrantFiled: May 2, 1997Date of Patent: June 1, 1999Assignee: Siemens AktiengesellschaftInventors: Michael Dittmann, Erich Vojta

Patent number: 5734308Abstract: Electromagnetic, monostable, small relay has a rocker armature arranged between a base plate and a coil, the armature being mounted with its middle segment at the end of an L-shaped yoke, and forming a working air gap with a second yoke. Contact springs are connected with the armature, which work together with fixed contacts anchored in the base. A resetting spring is connected with the armature and prestresses the armature into a rest position on the first yoke. For stabilization of the construction, and for separation between a contact chamber and a coil chamber, a base body is provided with an H-shaped cross-section, which overlaps the base plate in an interleaving manner, and which forms supports for the terminal pins of the base plate on both sides of the armature. In this way, a monostable relay is created, which can have any of conventional soldering pin terminals, SMT terminals, or press-fit terminals.Type: GrantFiled: December 19, 1996Date of Patent: March 31, 1998Assignee: Siemens AktiengesellschaftInventors: Michael Dittmann, Jens Heinrich

Patent number: 5673012Abstract: The relay has a rocker armature (3) arranged between a base (1) and a coil (7), which is drawn respectively into one of two switching positions by a permanent magnet (55). Contact springs (34) that work together with the fixed contacts (14) anchored in the base are connected with the permanent magnet. For the stabilization of the construction and for the division between a contact chamber (4) and a coil chamber (6), a main body, preferably with an H-shaped cross-section, is provided, which overlaps the base (1) in the manner of a box, and which comprises projections (57) on both sides of the armature, on which terminal pins of the base can be supported. Through the injection of sealing compound into the coil chamber (6), the construction obtains a high stability. In this way, with one and the same construction, conventional solder pin terminals, SMT terminals and press-fit terminals can be used.Type: GrantFiled: June 3, 1996Date of Patent: September 30, 1997Assignee: Siemens AktiengesellschaftInventors: Heinz Stadler, Michael Dittmann

Patent number: 5617066Abstract: The relay has a base (1) with stationary mating contact elements (11, 12, 13, 14), a coil (5), a permanent magnet (4) and also a rocker armature (3) which is arranged between the coil and the base, is connected to movable contact elements (21, 22, 23, 24) and is mounted on the base by means of bearing strips, the bearing strips simultaneously serving as electrical connections for the movable contact elements. The bearing strips (25, 26) are secured to the bearing supports (15, 16), which are designed as connection elements, of the base in planes extending at right angles to the basic plane of the base. As a result, the contact separation can be set with low tolerance even during production, and it is not dependent on tolerances of the individual parts. This structure consequently permits non-problematic, cost-effective production of the individual parts and accurate assembly without the requirement of subsequent adjustment.Type: GrantFiled: September 25, 1995Date of Patent: April 1, 1997Assignee: Siemens AktiengesellschaftInventors: Michael Dittmann, Heinz Stadler, Herbert Mitschik

Patent number: 5235301Abstract: A relay has a coil body (1) as a support for a magnet system and also a base. Coil connection elements (3, 4) serve for the connection between coil body and base, which coil connection elements are fastened with horizontal fastening legs (33, 34, 35, 43, 44) in corresponding horizontal insert channels (13, 14, 15, 16, 17) of the coil flanges (11, 12). In addition, wind-on pieces (36, 46) which directly support the winding ends of the coil are formed onto the coil connection elements (3, 4). This results in a manufacture of the relay with few component parts which is simple and can be automated.Type: GrantFiled: March 18, 1992Date of Patent: August 10, 1993Assignee: Siemens AktiengesellschaftInventors: Michael Dittmann, Horst Hendel

Patent number: 4745382Abstract: A relay comprises a spool with flanges (2, 3), an angular yoke (7) and an angular armature (9) positioned in front of the free end of the yoke (7). A contact element (8) attached to the free end of the yoke is provided for contacting of the relay spring (10c), which is connected with said armature. During the assembly process an armature assembly including an armature (9), connecting element (8) and leaf spring (10) is preassembled and subsequently mounted as a single unit onto the yoke (7). Since all connecting elements are connected with the spool or with the yoke, additional soldering to the base is not required. This physical configuration enables a fully automatic production of the relay.Type: GrantFiled: May 11, 1987Date of Patent: May 17, 1988Assignee: Siemens AktiengesellschaftInventor: Michael Dittmann

Patent number: 4684909Abstract: An electromagnetic relay has a coil body with a core yoke formed from flat stock with a core leg extending through the coil body. A yoke leg, also formed from the same piece of flat stock, is disposed over or next to the coil in a plane which is at a right angle relative to the plane of the core leg. An armature is disposed at the free end of the yoke leg, forming a working air gap with the free end of the yoke leg and being mounted for movement on a leaf spring pivotable about a bearing location. The free end of the armature forms the contact spring which cooperates with a stationary contact element. A connection element functioning as a terminal is also integrally formed from the same piece of flat stock. Additional coil connection elements are secured in the coil body by being plugged therein. The relay assembly is mounted on a base which forms a portion of the housing in combination with a cap placed over the base covering the assembly.Type: GrantFiled: March 18, 1986Date of Patent: August 4, 1987Assignee: Siemens AktiengesellschaftInventor: Michael Dittmann

Patent number: 4684910Abstract: An electromagnetic relay includes a coil having a winding between two coil flanges wherein one of the coil flanges forms a pocket-shaped contact chamber. An angled yoke is provided for the coil on which is seated a flat armature that is secured by an armature retaining spring. Male retaining members extending from the angled yoke mount the retaining spring and can be bent to set the armature restoring force. Separation of the moving parts of the relay at an end face of one coil flange from the winding enables casting compound to fill the winding space and seal the contact chamber.Type: GrantFiled: August 8, 1986Date of Patent: August 4, 1987Assignee: Siemens AktiengesellschaftInventors: Michael Dittmann, Heinz Stadler
