Molded Plastic Missile Lever Arm Assembly

In the preceding article, there is described wire matrix structure wherein the housing which supports the elements which make up the wire matrix printer assembly is made of molded plastic.

In the present structure, not only is the support made of plastic but the lever arm itself is made out of plastic and is unitary with the hinged housing structure. The resulting structure is diagrammatically shown in the figure. Lever arm 10 is part of a molded plastic member 11 which comprises armature assembly 12 in which the armature is embedded and is pivotable about hinge member 13 when activated by a coil 14 embedded in stator assembly 15. The structure is individually molded and positioned into a suitable opening 16 which serves to locate the molded lever arm assembly in the overall wire matrix assembly through a combination of locating tang 17 which mates with opening 16 to position the lever arm assembly in the overall wire matrix assembly support 18.

The use of such a molded plastic arm results in a lower inertia for the lever arm because of the higher strength to weight ratio of molded plastic over steel. In addition, there is improved manufacturability of the lever arm actuator. By molding the lever arm into the armature, the need for a separate lever arm metal laminate is eliminated.
