An electromagnetic relay includes a housing, a pair of fixed terminals, a movable contactor that is movably disposed so as to approach and separate from a fixed contact placement surface of each of the pair of fixed terminals, a movable shaft capable of moving in conjunction with the movable contactor, electromagnetic drive unit that drives the movable shaft to move the movable contactor in a moving direction, and an attenuation mechanism unit that includes an insulating attenuation member disposed between the movable contactor and the electromagnetic drive unit, and a sound insulating gap provided between the attenuation member and the electromagnetic drive unit.

Electromagnetic relay

An electromagnetic relay includes a box-shaped insulating housing in which a closed space is formed, a pair of fixed terminals fixed to the housing electrically independently of each other and each having a fixed contact placement surface in the closed space, a plate-shaped conductive movable contactor that is provided in the closed space, has a first surface facing the fixed contact placement surfaces of the pair of fixed terminals, and is movably disposed such that the first surface approaches and separates from the fixed contact placement surfaces of the pair of fixed terminals, a pair of fixed contacts respectively provided on the fixed contact placement surfaces of the pair of fixed terminals, and a pair of movable contacts that is respectively provided on the first surface of the movable contactor and respectively face the pair of fixed contacts.

Electric relay

An electromagnetic relay has a fixed touch piece having a fixed contact, a movable touch piece having a movable contact contactably and separably opposed to the fixed contact, and configured to elastically deform, an auxiliary member configured to energize the movable touch piece to the fixed contact piece side, an electromagnet, and an intermediate member configured to be operated by magnetization of the electromagnet and elastically deform the movable touch piece.

An electromagnetic relay has a fixed touch piece having a fixed contact; a movable touch piece, having a movable contact contactably and separably opposed to the fixed contact, and configured to elastically deform, an electromagnet, an intermediate member that rotates based on magnetization and demagnetization of the electromagnet and elastically deforms the movable touch piece, and an energization unit that energizes the movable touch piece to the fixed contact piece side via the intermediate member.

To promptly extinguish an arc generated between contacts with a simple and inexpensive structure without negatively influencing the spring property of a movable contact piece. A contact switching mechanism includes a fixed contact piece with a fixed contact and a movable contact piece with a movable contact which faces the fixed contact in a contactable manner. At least either one of the contact pieces is provided with an extension which extends toward the contact of the remaining contact piece.

Contact switching mechanism and electromagnetic relay

Provided is a technology which has a simple structure, is easy to manufacture, and does not increase cost. A terminal member to be press-fitted into a terminal hole formed in a base, includes a press-fitted portion which is to be press-fitted in the terminal hole, and a terminal portion extending from the press-fitted portion and protruding from the base. The terminal portion is formed by folding a plate-like body such that folded portions overlap a planar portion. At least one of the folded portions has a cut-away portion extending from the base, respectively at an edge near the press-fitted portion. A sealing agent can be injected into the terminal hole via the cut-away portions.
