Abstract: In an electromagnetic relay wherein one of the flanges 2b of the spool 2 is located inside of the opening of the case and a stationary terminal 11 is attached to this spool 2, the problem of dust occurrence due to the attachment of the stationary terminal 11 is solved so as to implement the attachment of the stationary terminal (in particular, a portion to which a stationary contact point 10 is provided) in an excellent condition. In order to achieve this, protruding portions 11e and 11f extending from the stationary terminal 10 are compressively inserted into through holes 2e and 2f configured in the flange 2b and the vicinity of the stationary contact point of the stationary terminal 11 is engaged with the engagement portion 2f formed on the other flange 2a and, thereby, the stationary terminal 11 is attached to this structure.

Abstract: An electromagnetic relay, comprising: a electromagnet consisting of an iron core and a solenoid wound thereon; a yoke extending in parallel with the electromagnet and attached to one end of the iron core; an armature pivotally attached to a part of the yoke adjacent to another end of the iron core at its base end; a fixed contact unit provided adjacent to the electromagnet; an pivotally supported moveable contact carrier; an extension arm extending from the armature and having a free end adapted to abut an actuation point of the moveable contact carrier located between its pivoted point and a moveable contact piece carried thereby; the moveable contact piece being adapted to cooperate with a fixed contact member provided in the fixed contact unit.

Abstract: An electromagnetic relay where a movable stand is retained by a pair of opposing leaf springs, the movable stand is operated in the opposing direction of the leaf spring in accordance with the energization, deenergization of the electromagnet, the movable terminal is disengageably brought into contact against the fixing terminal supported through the support stand, and the movable stand is provided with a through hole in the vertical direction to be press-fitted, mounted in it, a groove in the vertical direction in the contact portion of the movable stand and the leaf spring, and a passage for guiding into the groove portion the bonding agent to be put into the through hole.

Abstract: As thin type yoke having excellent magnetic characteristic to including a pair of yoke segments having a wide iron segment attracting part which is extended and bent at the one end of a coil winding part, wherein said coil winding part is offset in the lateral direction and the end part thereof is mutually and placed in contact with the wide iron segment attracting part of the other yoke segment.

Abstract: The electromagnetic relay has a pair of normally closed and normally open fixed terminals which are disposed opposing each other. At least two normally closed fixed contacts are mounted on the normally closed fixed terminal, and at least two normally open fixed contacts are mounted on the normally open fixed terminal. The normally closed and normally open fixed terminals are commonly used by a plurality of relay units. Therefore, the relay can be small enough to be installed on a small area, and allows high-density electric circuits to be provided on circuit boards.

Abstract: An electromagnet device is assembled to, e.g., an electromagnetic relay. This device comprises a movable assembly which is swingably supported and a core in which a coil is wound around a part thereof. The movable assembly has two magnetic plates arranged so as to face each other with a distance and one permanent magnet arranged between those magnetic plates. Each magnetic plate has operating portions at both end portions thereof in which magnetic poles appear due to the permanent magnet. The core has two end portions which are arranged so as to respectively face the operating portions of the magnetic plates. At least one of the operating portions which faces at least one of the end portions of the core is formed at the edge surface of the magnetic plate.

Abstract: An improved electromagnetic relay in which movable contact pieces of contact mechanisms are fitted into grooves formed in arm portions of a movable base for a movable block, while small projections formed on the movable contact pieces are fitted into recesses further formed in the grooves so as to fix the movable base to the movable contact pieces without any positional displacement or deviation for the prevention of various characteristic variations resulting from such deviation so as to maintain stable working characteristics over a long period.

Abstract: An electromagnetic relay comprising an electromagnet constituted by an I-like core and a coil wound around the core, a pair of contact mechanisms disposed at both sides of the electromagnet, respectively, a pair of permanent magnets disposed in parallel with the core in such magnetic orientation that the magnetic poles of the permanent magnets each positioned adjacent to each lateral end faces of the I-like core exhibit different polarities, the permanent magnets being interconnected by connecting beam members at both ends to thereby constitutes a frame-like movable armature, a H-like holder having four upstanding legs positioned in opposition to the lateral end faces of the I-like core, respectively, with the permanent magnet being interposed between the legs and the core, actuating members operatively coupled to the permanent magnetic for actuating the contact mechanisms in response to the movement of the armature frame, and a restorting spring for the movable armature frame.
