Abstract
A modified wire guide and assembly method for facilitating the insertion of wires into a dot matrix print head. In the preferred embodiment, the wire guide has a planar surface with downwardly extending wire holes defined by first and second surfaces. The first surface has a truncated conical shape and the second surface has a cylindrical shape. Additionally, the wire guide has an upwardly extending, inclined cam surface that intersects the planar surface to form a closed path. The first surface defining each hole is positioned adjacent the cam surface and intersects the closed path so that a wire striking the cam surface will move down it toward and into one of the holes. The assembly method of the present invention involves inserting a wire through three wire guides using aids that apply a first force in a first direction to bow the wire and then apply a second force in an opposite direction to guide the wire through the print head.
