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).
