Abstract

The present structure provides a protective shield for printed circuit board edge connectors which prevents failures caused by contamination of these connectors through paper dust, particularly when printed circuit structure is used in impact printers and typewriters. The protective shield which is shown in the figures includes a cover 2 over edge connectors 3 which extend from vertical daughter board 1 which is plugged into edge connectors 3 in turn connected to a horizontal mother board 4.

Protective Contamination Shield for Circuit Board Edge Connectors

The present structure provides a protective shield for printed circuit board edge connectors which prevents failures caused by contamination of these connectors through paper dust, particularly when printed circuit structure is used in impact printers and typewriters. The protective shield which is shown in the figures includes a cover 2 over edge connectors 3 which extend from vertical daughter board 1 which is plugged into edge connectors 3 in turn connected to a horizontal mother board 4.

The protective shield 2 may be die cut or molded from a material such as polyvinyl chloride. Surface 5 around holes 9 is extruded to provide a spring effect to maintain the parts under tension when they are assembled. The pins 6 are constructed such that they have a shoulder 7 somewhat larger than the hole to maintain the cover 2 firmly against the vertical daughter board 1.
