Embodiment Construction

[0037] Below, refer to Figure 1 to Figure 5 Embodiments of the present invention will be described.

[0038] like Figure 1 to Figure 4 As shown, the electromagnetic device 50 of the first embodiment is suitable for a self-resetting electromagnetic relay used for opening and closing a high-frequency circuit.

[0039] That is, in the electromagnetic relay of this embodiment, the electromagnetic device 50 is assembled in the space formed by integrally fitting the housing 90 on the base block 10 , and the electromagnetic device 50 assembles the movable iron piece 70 on the electromagnetic block 60 .

[0040] The base block 10 is configured by sandwiching the base 11 on which the pair of movable contact blocks 30 and 35 are assembled from the bottom and the bottom by the lower sealing plate 20 and the upper sealing plate 40 .

[0041] The base 11 is formed by inserting the common fixed contact terminal 12 cut out from the lead frame (not shown), the normally open fixed contact...

Abstract

The invention provides an electromagnet device which can make height of a contacting portion of a moveable iron piece have no difference, does not need to adjust action characteristic and has low cost. The electromagnet device has a movable iron piece having an end that is operable to contact and separate to and from a magnetic pole portion of an iron core. The movable iron piece rotates based on magnetization and demagnetization of a coil wound around the iron core. A tapered surface is formed on at least one end of an attraction surface of the movable iron piece, which attracts to and separates from the magnetic pole portion of the iron core. At least one contacting portion that is in flush with and continuous to the attraction surface and in contact with the magnetic pole portion of the iron core is arranged in a projecting manner on the tapered surface.

Description

technical field [0001] The invention relates to an electromagnetic relay, in particular to the shape of the movable iron piece of the electromagnetic device used in the electromagnetic relay. Background technique [0002] Conventionally, there is an electromagnetic device having a structure in which, as a movable iron piece of the electromagnetic device, for example, the end of the movable iron piece that rotates based on excitation and demagnetization of a coil wound on an iron core approaches and separates from it. The contact is opened and closed by driving the movable contact spring integrated with the movable iron piece (see Patent Document 1). [0003] However, both ends of the movable iron piece in contact with the magnetic pole portion of the iron core are flat surfaces, and the suction surface of the movable iron piece is in surface contact or line contact with the magnetic pole portion of the iron core. And, in the state where the movable iron piece and the magnet...
