A terminal block includes a housing that has an opening through which a wire is to be inserted, a terminal configured to be connected to the wire that is inserted through the opening, and a plate spring member configured to fix the wire by pressing the wire against the terminal. The plate spring member has a pressing portion configured to press the wire against the terminal, and a plastic deformation preventing portion configured to prevent the pressing portion from bending in a direction away from the terminal by more than a predetermined amount.

Terminal block

An electromagnetic relay is provided with an iron core ( ) which has a virtually J-letter shape on a plan view with one end serving as a support-receiving portion ( ) and the other end serving as a magnetic pole portion ( ), and a movable iron member ( ) which is supported by a movable contact member ( ) attached to a corner thereof, and has a virtually L-letter shape on a plan view with one end ( ) being supported on the support-receiving portion ( ) of the iron core ( ) so as to freely pivot thereon and an adsorb portion ( ) that is the other end being allowed to face the magnetic pole portion ( ) of the iron core ( ) so as to be adsorbed thereon. The objective of the present invention is to provide an inexpensive electromagnetic relay which is less susceptible to deviations in the adsorb portion of the movable iron member that comes into contact with and separates from the magnetic pole portion of the iron core, and has stable operation characteristics.

Electromagnetic relay

The invention provides an improved heat seal structure for electronic devices. A heat seal structure comprises a base of synthetic resin formed integrally with an outwardly extending projection, with a gas vent running through the base and projection, the gas vent being sealed off by melting the projection, the improvement that the gas vent is configured generally in the shape of the letter V or Y bifurcating in the outward direction. In another embodiment, the projection has an annular extension disposed on the outward side of the base and adapted to be melted for a double seal effect. In another version of the structure, heat-sealing is performed with a sealing member or composition interposed in the gas vent. In still further embodiments, heat sealing is performed using a sealing member melting at a temperature below the melting point of the resin forming the base.
