An electromagnetic relay includes a fixed contact, a movable contact corresponding to the fixed contact, a movable element that retains the movable contact and moves in a contacting direction and a separating direction relative to the fixed contact, an axial core coupled to the movable element, a movable core coupled to the axial core to move in the contacting direction and the separating direction relative to a movement of the axial core, a driving part that drives the movable core in the contacting direction, an urging part that exerts force to the axial core in the separating direction, and a constraining part that constrains the relative movement of the axial core in the separating direction.

An electromagnetic relay includes: an electromagnet; a twin contact set that includes first twin contacts provided on a first movable spring, and second twin contacts that are provided on a first fixed contact plate and disposed opposite to the first twin contacts; a single contact set that includes a first single contact provided on a second movable spring, and a second single contact that is provided on a second fixed contact plate and disposed opposite to the first single contact; and a card that moves in response to excitation or non-excitation of the electromagnet, and moves the first and the second movable springs simultaneously with the movement of the card.

A relay includes an electromagnet, a plurality of springs having contacts which open and close in accordance with operation of the electromagnet and terminals, and a base which supports the springs, wherein at least one of the plurality of springs has a locked part which is locked on the base using resilience of the spring, and the base has a lock part which locks the locked part.

An electromagnetic relay includes a base, a spool provided on the base, a coil wound on the spool, a yoke inserted into a hole formed in the spool, an armature movably provided on the base, a movable contact fixed on the base, a static contact fixed on the base, and a driving member connected between the armature and the movable contact. The yoke is L-shaped. The yoke and the armature form a rectangular magnetic loop.

A high-insulation small-sized hinged electromagnetic relay, includes a bobbin, coil terminals, an iron core and a fixed contact block. The bobbin has a cylindrical portion for winding a coil, and the iron core includes a mandrel and a magnetic pole portion arranged on the upper end of the mandrel; the mandrel of the iron core is fitted into the central hole of the cylindrical portion of the bobbin, the coil terminals is assembled on the lower flange of the bobbin and positioned on one side in the width direction of the bobbin, and the fixed contact block is interposed in the upper flange and the lower flange of the bobbin and positioned on the other side in the width direction of the bobbin; the cylindrical portion is offset.

A relay includes an electromagnet, a plurality of springs having contacts which open and close in accordance with operation of the electromagnet and terminals, and a base which supports the springs, wherein at least one of the plurality of springs has a locked part which is locked on the base using resilience of the spring, and the base has a lock part which locks the locked part.

An electromagnetic relay includes a base, a first terminal, a fixing member, and a first adhesive. The base includes a first hole. The base is made of a thermosetting resin. The first terminal extends through the first hole. The fixing member is a separate body from the base. The fixing member has higher elasticity than the thermosetting resin. The fixing member fixes the first terminal to the base. The fixing member includes a first support wall and a first recess. The first support wall is disposed between an inner surface of the first hole and the first terminal. The first support wall extends upward along the first terminal. The first recess is disposed on an upper surface of the first support wall and faces the first terminal. The first adhesive is filled in the first recess. The first adhesive adheres the first terminal and the first support wall.

An electromagnetic relay includes a fixed terminal, a movable contact piece, and a support portion supporting the fixed terminal. The fixed terminal includes a fixed contact, a first terminal portion on which the fixed contact is disposed, a second terminal portion extending from one of both ends of the first terminal portion, a first protrusion disposed on the second terminal portion. The fixed terminal is bent between the first and second terminal portions. The first terminal portion has a first terminal surface opposite to the movable contact piece. The second terminal portion has a second terminal surface connected to the first terminal surface. The support portion has a contact surface contacting the first terminal surface of the first terminal portion, and a first side surface including a first groove where the first protrusion is fitted. The first protrusion is disposed on the second terminal surface of the second terminal portion.

An electromagnetic relay includes a first fixed terminal, a base, and a magnet. The first fixed terminal includes a first fixed contact. The base holds the first fixed terminal. The base includes a magnet insertion hole disposed in a vicinity of the first fixed contact. The magnet insertion hole has an opening opened toward the first fixed terminal. The magnet is disposed in the magnet insertion hole and is prevented from coming off from the magnet insertion hole by the first fixing terminal.
