Patent number: 5515019Abstract: A relay has a polarized magnetic system (2) with a three-pole magnet (17) arranged above a coil (14) and rocking armature (18) which actuates a contact spring (30) arranged beneath the coil by means of a frontally arranged slide (23). The contact spring (30) is inserted from one side into the base body, by means of an elongated spring carrier (29), whereas a counter contact element (33) is inserted therein from the opposite side. This relay allows with a compact design long insulating sections between the magnetic system and the set of contacts, as well as a short circuit-resistant design of the set of contacts.Type: GrantFiled: November 8, 1994Date of Patent: May 7, 1996Assignee: Siemens AktiengesellschaftInventor: Helmut Schedele

Patent number: 5289145Abstract: An electromagnetic system having a coil (8), a yoke (10) and an armature (11) is arranged in the upper region of the cap in the relay having a housing cap (1) which is closed at the top, while a contact system (5, 6, 7) is mounted in the lower region in the vicinity of the connection side of the relay. Coil connecting elements (20) are embedded in each case in one side wall of the cap (1), for the connection of the coil winding, in such a manner that their ends open on the top of the cap in each case in a depression (18) which is open to the exterior. During the assembly of the magnet system, winding supporting elements (15), which are provided in each case on the coil former, are inserted into these depressions. The ends of the winding supporting elements (15) and of the coil connecting elements (20) are then be electrically conductively connected from the exterior by soldering or using a conductive adhesive.Type: GrantFiled: October 9, 1992Date of Patent: February 22, 1994Assignee: Siemens AktiengesellschaftInventor: Helmut Schedele

Patent number: 5250919Abstract: In a relay, the magnet system is mounted in the upper zone of a cap-shaped housing, while the contact system (8) is inserted into the housing from the open underside until the contact (91, 92) closes when the magnet system is excited. After further insertion by a prescribed extra way, the contact system (8) is connected to the housing (1) without a stop at its edge (82a). It is therefore possible to compensate manufacturing tolerances during assembly, so that subsequent adjustment of the contact system is not required.Type: GrantFiled: May 6, 1992Date of Patent: October 5, 1993Assignee: Siemens AktiengesellschaftInventor: Helmut Schedele

Patent number: 5243312Abstract: The relay has an actuation member (7) which is connected to the armature (6) and which covers by means of a partition (76) the entire surface between the magnet system (2, 4, 5) and the contact system (8) and also surrounds the contact system (8) and/or the magnet system (2, 3, 4, 5) with integral side walls (71, 72, 74) in the form of a tub. As a result, very long creepage distances and clearances between the coil and the contact system are ensured in a relay of small dimensions.Type: GrantFiled: January 27, 1992Date of Patent: September 7, 1993Assignee: Siemens AktiengesellschaftInventor: Helmut Schedele

Patent number: 5144270Abstract: A relay with a moveable contact element which is actuated through armature movement transmitted via a slide is switched by the application of torsional forces to the movable contact element. The torsional forces are generated by the slide pushing the leaf spring contact element eccentrically in the region of one edge so that twisting of the contact element occurs during the switching event. A lower spring modulus for a spring of predetermined thickness and dimensions result so that a smaller magnetic system and a smaller overall relay is achieved given matching of the spring force curve to the magnetic system force curve.Type: GrantFiled: July 3, 1991Date of Patent: September 1, 1992Assignee: Siemens AktiengesellschaftInventors: Helmut Schedele, Franz Rappl

Patent number: 5144271Abstract: In an electromagnetic power relay, a spring carrier and a cooperating contact element are plugged into slots in a base member from two opposite sides. Terminal rails extending parallel along the outside walls of the base member to an end face of the relay have, at the end face, portions which are crimped inwardly within pockets in the housing cap. The terminal elements then emerge from the outside walls of the relay at a predetermined insulating distance from the side walls of the relay and form solder and plug terminals. Within the pockets, the terminal elements are provided with fastening projections for anchoring, the fastening projections lying in the inwardly offset planes of the terminal elements. An adequate insulating distance from the side walls of the relay is, thus, provided so that the relays may be tightly grouped on a printed circuit board.Type: GrantFiled: July 3, 1991Date of Patent: September 1, 1992Assignee: Siemens AktiengesellschaftInventor: Helmut Schedele

Patent number: 5008641Abstract: A relay having a coil body with two contact spaces extending parallel to the coil body axis is provided with two tongue armatures arranged oppositely in parallel fashion through the contact spaces. The coil body has coil flanges at the opposite ends and the tongue armatures are plugged into the contact space from opposite one of the coil flanges to extend to an air gap between pairs of pole pieces arranged at the other coil flange. The pole pieces are arranged in pairs adjacent the terminal end of the other tongue armature. On each of the pairs of pole pieces is a flat four-pole permanent magnet having two outside poles coupled to a contact end of the appertaining tongue armature via a flux plate. The permanent magnet areas which are allocated individually to each pole piece to enable independent balancing to be performed so that synchronous switching of the tongue armatures is achieved.Type: GrantFiled: May 31, 1990Date of Patent: April 16, 1991Assignee: Siemens AktiengesellschaftInventor: Helmut Schedele

Patent number: 4672344Abstract: A polarized electromagnetic relay has an armature extending through an axial opening in a coil body, a free end of the armature being switchable between two planar pole plates. The pole plates each have pole members disposed opposite one another and each further have top and bottom stop tabs received in spacer members which are a part of a flange of the coil body. Each pole plate with the pole members and stop tabs is stamped in a single cutting from sheet material. By positioning the stop tabs within the spacer members, a precise contact spacing between the two pole plates is insured with a low tolerance during assembly.Type: GrantFiled: April 14, 1986Date of Patent: June 9, 1987Assignee: Siemens AktiengesellschaftInventor: Helmut Schedele

Patent number: 4609896Abstract: A polarized miniature relay incorporates a rod-shaped armature pivotally mounted at one end and axially arranged within the coil member with its free end projecting between two oppositely magnetically polarized pole shoes coupled with two opposite poles of a quadripole permanent magnet. A flux plate is connected to the other poles of the permanent magnet and has an aperture which supports the armature for pivoting motion in contact therewith. A very low reluctance for the magnetic circuit results in the magnetic flux paths of the relay.Type: GrantFiled: June 18, 1985Date of Patent: September 2, 1986Assignee: Siemens AktiengesellschaftInventor: Helmut Schedele

Patent number: 4602230Abstract: An improved polarized relay characterized by a coil body being received in a recess of a base body along with a permanent magnet arrangement which has a pair of pole plates extending in a common plane with portions bent to form an air gap for receiving a free end of an armature, a flux plate extending perpendicular to the axis of the coil and having a recess to mount the armature and segments extending parallel to the pole plates to form spaces for receiving at least one permanent magnet with the recess being entirely closed by a protective covering so that the only exposure of the magnet arrangement and coil to the contacts is through an opening in which the armature extends to actuate the movable contact element. The polarized relay due to the insulation of the magnet arrangement and the coil is particularly adapted for contacts handling high currents at high ambient temperatures.Type: GrantFiled: December 20, 1984Date of Patent: July 22, 1986Assignee: Siemens AktiengesellschaftInventor: Helmut Schedele
