The adhesive is filled in a gap between the side part and the inner surface.

An assembled member including a press-fit part, a molded part having a hole into which the press-fit part is press-fit, and a lid provided on the press-fit part or the hole so as to form a closed space for holding shavings between the hole and the press-fit part when the press-fit part is press-fit into the hole.

The disclosure provides an ultra-small electromagnetic relay with high stationary contact positioning precision, comprises: a stationary spring, a bobbin and a base which are integrated by injection molding, the stationary spring comprises a stationary spring body on which stationary contacts are disposed and a leading-out terminal of the stationary spring extending from the stationary spring body to an outer part of the base; in the leading-out terminal, a first positioning part is disposed at a position corresponding to an edge of the base; in the stationary spring body, a convex extending part extending outside the base is designed as a second positioning part; in the base, a through hole formed through the base of is provided at a position corresponding to a back surface of the stationary spring body on which the stationary contact is mounted, the back surface is designed as a third positioning part during injection molding.

The present disclosure provides a highly-reliable insulating ultra-small electromagnetic relay, comprising a coil portion and static spring portions. The coil portion comprises a bobbin; the bobbin comprises two flanges that are located at the two end portions of the bobbin; each static spring portion comprises a static spring provided at at least one end of the bobbin; the static spring comprises a contact portion comprising a static contact; the contact portion of the static spring is provided at the position close to the flange of the bobbin; and in each flange of the bobbin, a first retaining wall and a second retaining wall used for together limiting the position of the contact portion of the static spring in two horizontal directions are respectively and upwardly arranged in a protruding mode.

An electromagnetic relay includes: a fixed terminal including a fixed terminal main body extending in a first direction, a fixed terminal arm portion, and two fixed contacts; a movable spring including two movable contacts, and extending in a second direction; a backstop; and a fixed terminal retainer. One of the fixed terminal main body and the fixed terminal arm portion is a first side terminal portion facing in the second direction, and the other is a second side terminal portion curving from a first edge of the first side terminal portion in a direction opposite to the second direction. A leg portion of the backstop is provided away from the first side terminal portion in the direction opposite to the second direction, and is provided between the two movable contacts on a projection plane with a perpendicular extending in the second direction when viewed from the first direction.

An electromagnetic relay includes a base, a fixed terminal, a fixed contact, a movable piece, a movable contact, a magnet, a base holder, and a case. The fixed terminal is supported by the base. The fixed contact is connected to the fixed terminal. The movable piece is supported by the base. The movable contact is connected to the movable piece and faces the fixed contact. The magnet exerts a Lorentz force on an arc generated between the fixed contact and the movable contact. The base holder is a separate body from the base. The base holder is attached to the base. The base holder is disposed in at least a direction in which the Lorentz force acts with respect to the base. The case is attached to the base holder.

A motor protection relay including a housing and a printed circuit board disposed within the housing, the printed circuit board including a central processing unit and a wireless communication interface, the wireless communication interface adapted to receive wireless communication signals for configuring operating parameters of the motor protection relay via the central processing unit.

An electronic-device seal structure includes a base, a case which covers an upper surface of the base and has an opening at a surface thereof, and a pair of terminals attached to the base. A first clearance sealed with a sealing material is provided between the base and the case, and a second clearance is provided between the pair of terminals attached to an end surface of the base to face each other.

A cradle for a relay comprises a force introduction section at which a force is introduced from a triggering system and a force diversion section in which the force that is introduced from the triggering system is diverted to a contact system. A direct connection line extending between the force introduction section and the force diversion section runs through a receptacle. A bottom of the receptacle is spaced apart from the direct connection line.

An electromagnetic relay includes an armature, and a movable body configured to move in association with a swing of the armature. The armature includes a support portion opposed to a leg portion of an iron core, a magnetic pole opposed to another leg portion of the iron core, and an arm portion extending to connect the support portion and the magnetic pole. A movable body is attached to the arm portion and provided with a pressure projection for moving movable contacts. The pressure projection is located on a segment connecting the center of gravity of the support portion and the center of gravity of the magnetic pole.
