Method and apparatus for pressure-welding an electric wire to a pressure terminal

Abstract

A method and apparatus for pressure-welding an electric wire to a pressure terminal in a manner that minimizes the deformation of pressure-welding cutters when the connection wire is pressed fit into the pressure terminal and provides electrical connections. An electric wire pressure-welding apparatus (1) is provided with a guide (9) constituting a vertically-extended fixed member, side pressing plates (6) constituting moving members each capable of pivoting about shafts (8) arranged in the upper portions of grooves (9a) longitudinally cut in the respective sides of the guide (9), and a sleeve (5) vertically slidable along the outer surfaces of the guide (9), and pressure-welding dies (2) each secured to the lower portion of the sleeve. An insulated wire (20) is laterally held and compressed by the side pressing plates (6) before or at the same time the insulated wire (20) is pressed fit into the cutting slots (22) of pressure cutters (21) so that the insulation of the wire is cut and the pressure cutter electrically contacts the wire conductor.
