A nut-fixing part,formed in a housing,has a nut-holding room,, where a nut,is insertable and detachable by a movement in a direction perpendicular to the thickness direction of the nut,. At the entrance of the nut-holding room,, a projection,is provided to prevent the inserted nut,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.

Nut-prefixed connector

An electrical connector has an insulative housing, a fixture, and a shield. The fixture is used for fixing this insulative housing on a circuit board, and the shield is to cover the insulative housing. The insulative housing, which is made of an electrically insulating material, comprises a main body and an engaging portion, which protrudes forward from the main body to engage with a matable connector. The insulative housing also comprises fixture retaining slots, which extend through the main body in the vertical or to-and-fro direction at the lateral ends of the main body of the housing. Into each of these fixture retaining slots, a fixture, which is made of an electrically conductive metallic material, is press-fit to fix the insulative housing onto a circuit board. The shield, which is made of an electrically conductive metallic material, comprises a peripheral portion and contact portions in a one-piece body. The peripheral portion covers the perimeter of the engaging portion of the insulative housing, and each of the contact portions extends into a respective fixture retaining slot. With this construction, each fixture is retained in contact with a respective contact portion in a respective fixture retaining slot grounding the shield when the electrical connector is mounted on a circuit board with the fixtures being surface-mounted onto grounding pathways on the circuit board.
