In wire matrix printers it is necessary to electrically connect a movable printhead to logic which causes the print wires to be actuated. As the printhead moves up and back across the paper, the wires are bent and tend to break. The technique disclosed herein consists of making the cable guide 10 with a predetermined curved chamber 12, as shown in Fig. 1. The cable guide 10 may be a metal strip, including printed wires connecting the logic in the printhead 14, as shown in Fig. 2. The curve will maintain a predicted and constant radius of bend 16 on the strip. This will result in a predicted applied stress due to the bending. Without the curve, the radius is unpredictable and will expand to fill all of the space.
