Patent number: 7157994Abstract: For manufacturing a thin electromagnetic relay having desired attractive force, both arms as upstanding portions disposed at both ends of a barrel of a plate magnetic material which is punched to be substantially U-shaped as viewed from the front by press working are bended to form magnetic poles having magnetic-pole surfaces extending in a horizontal direction. A vertical face passing through the center of the barrel crosses the centers of the magnetic-pole surfaces at right angles. The width of the barrel is smaller than the height of the barrel.Type: GrantFiled: April 29, 2005Date of Patent: January 2, 2007Assignee: Omron CorporationInventors: Ryota Minowa, Keisuke Yano, Takeshi Nishiyama, Hironori Sanada

Patent number: 7116193Abstract: A relay is provided that has a base, connecting elements, a magnet system with a coil, a core arranged within the coil, an L-shaped yoke, and a plate-shaped armature, wherein the axis of the coil extends parallel to the first yoke leg, and a second yoke leg is connected to the first end of the core farthest from the base, and wherein the armature is pivoted on the first yoke leg and forms a working air gap with a second end of the core facing the base. A contact system has a contact spring that is fastened to the armature and carries a movable contact, and at least one fixed contact carrier that carries a fixed contact and is anchored in the base. The open end of the first yoke leg is supported on the upper surface of the base with two fork-shaped end sections, while the open end of the second yoke leg is likewise supported on the upper surface of the base by a yoke support parallel to the first yoke leg.Type: GrantFiled: September 29, 2004Date of Patent: October 3, 2006Assignee: Hella KGaA Hueck & Co.Inventor: Robert Campbell

Patent number: 7106154Abstract: An electromagnetic relay including a base having a first receptacle, a second receptacle and a partition wall defining the first and second receptacles on mutually opposite sides of the partition wall. The partition wall includes a major part and an auxiliary part, the major part being provided with a local opening. An electromagnet assembly is received in the first receptacle of the base and includes an electromagnet and an armature. The armature includes an extending portion extending in a direction toward the second receptacle of the base through the local opening of the partition wall. The auxiliary part of the partition wall is disposed between the electromagnet and the extending portion of the armature. A contact section is received in the second receptacle of the base. An actuating member is arranged between the electromagnet assembly and the contact section, and includes an envelope part for enclosing at least a part of the extending portion of the armature.Type: GrantFiled: August 12, 2004Date of Patent: September 12, 2006Assignee: Fujitsu Component LimitedInventors: Satoshi Takano, Shigemitsu Aoki

Patent number: 7053738Abstract: A relay and a process for producing a relay are described, three contact pins being provided for the relay. The three contact pins are preferably manufactured from a stamping and are fixed together as a contact stamping with respect to a yoke through insertion into a base. As a result of the use of a contact stamping with the three contact pins connected rigidly to one another, adjustment and handling of the three contact pins during production of the relay is relatively simple.Type: GrantFiled: February 11, 2005Date of Patent: May 30, 2006Assignee: Tyco Electronics AMP GmbHInventors: Ralf Hoffmann, Thomas Haehnel, Ralf Gollee, Joerg Schultheiss, Olaf Abel

Patent number: 6940375Abstract: An electromagnetic relay makes it difficult for deformation due to impact force to easily occur even when bending work is applied to a contact plate. A coil block is put on a base and a moving contact plate and fixed contact plates are so juxtaposed as to oppose one another. The moving contact plate is constituted by a contact-fitting portion to which a moving contact is fixed, a push-in fixing portion which is pushed in and fixed to the base and from which terminal portions extend, and a connection portion for connecting the contact-fitting portion and the push-in fixing portion. The connection portion has a width smaller than those of the contact-fitting portion and the push-in fixing portion.Type: GrantFiled: November 12, 2003Date of Patent: September 6, 2005Assignee: Omron CorporationInventors: Hironori Sanada, Hiroyasu Tanaka, Hiroaki Yamazaki

Patent number: 6903639Abstract: An electromagnetic relay prevents appropriately invasion of a sealant. A coil block 3 produced by winding a coil 29 on a core 27 through a spool 28 and connecting the coil 29 to coil terminals 42 disposed at flanges 28a and 28b of the spool 28 is put onto a base 1. The through-holes 15 are sealed under the state where the coil terminals 42 protrude from the through-holes 15 formed in the base 1. An attraction surface 27a of the plate 27 is positioned on the side of the base 1 so that a moving iron plate 32 can be attracted and operated between the coil block 3 and the base 1. An increased thickness portion 41 into which the coil terminal 42 can be pushed is formed in each flange 28a, 28b of the spool 28 and a recess 43 for storing a sealant entering inside from the through-hole 15 is formed around the coil terminal 42.Type: GrantFiled: October 28, 2003Date of Patent: June 7, 2005Assignee: Omron CorporationInventors: Hironori Sanada, Hiroyasu Tanaka, Hiroaki Yamazaki
