Abstract
A control rod (10) is grounded to a structure (14) at an opening (16) through which it moves longitudinally by sliding contact with a conductive wiper (18, 29, 40, or 48). The wiper is mounted to the structure (14) by conductive arms (26) and brackets (28), or by a joint (36), or by a housing (44), or by a boot (50) so that the wiper can track transverse motion of the rod (10).
Claims6
A structure having an opening therethrough, a control rod extending through said opening and being movable both longitudinally and transversely through the opening, and a grounding device providing an electrical path between said control rod and said structure;
- said grounding device including a conductive wiper surrounding and resiliently contacting the control rod while allowing for longitudinal motion of the control rod in the wiper;
- and
- mounting means attaching the wiper to the structure adjacent the opening while allowing for relative transverse motion between the wiper and the structure.
