Abstract: 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.

Abstract: An electromagnetic device includes a spool including a cylindrical body portion in which a through hole extending to a first direction is provided, a coil wound around the body portion, an iron core disposed in a through hole of the body portion, a yoke including a first member and a second member, the first member being connected to the iron core and the second member extending from the first member along an outer peripheral surface of the coil, and a movable iron piece, which has a plate shape, including a bent portion in a middle thereof. The yoke includes at least one positioning projection provided in a middle of the free end in the second direction. The movable iron piece includes a positioning recessed portion that accommodates and positions the positioning projection, the positioning recessed portion being provided in a middle between the pair of rotation supporting points.

Abstract: A screwless terminal block allows easy insertion and removal of a wire. A housing (2) includes a fixture insertion opening (23) through which a rod-like fixture (6) is inserted to come in contact with a contact pressure spring (4) and deform the spring (4) away from a wire (5). When the fixture (6) is inserted through the fixture insertion opening (23), an acute angle of 45° or less is formed by an axis of the fixture (6) and a straight line connecting a contact point A between the housing (2) and a part of the fixture (6) adjacent to the wire insertion opening (24) and a contact point B between the housing (2) and a part of the fixture (6) adjacent to the spring (4) at a cross-section taken along a plane including the axis of the fixture (6) and parallel to a pressing direction of the spring (4).
