摘要： A nut-fixing part 20 formed in a housing 10 has a nut-holding room 26, where a nut 30 is insertable and detachable by a movement in a direction perpendicular to the thickness direction of the nut 30. At the entrance of the nut-holding room 26, a projection 27 is provided to prevent the inserted nut 30 from sliding out. By this construction, this type of connector can be miniaturized further. In addition, when this connector mounted on a circuit board is heated in a furnace for soldering electrical connections, even if the housing experiences a stress relief, there is no possibility of any nut falling off from the housing.
