Terminal device for grounding direct current electrical component

摘要

A terminal device used in grounding direct current electrical components, such as audio amplifiers, having a metal contact plate provided with a first opening sized to receive a securing screw and having a second opening sized to receive a locking screw used to attach the terminal device to a metal member of another structure, wherein the first opening is positioned relative to the second opening so that with the securing screw attaching the metal contact plate to a grounding surface, the head of the locking screw will contact and apply anti-rotational forces against the head of the securing screw when the locking screw is also screwed into the grounding surface.

主权项

1. A terminal device comprising a grounding wire receiving section to affix a ground wire to the grounding wire receiving section and a metal grounding plate section having a securing screw opening and a locking screw opening to receive a securing screw comprising a securing screw head section having a predetermined diameter and a locking screw comprising a locking screw head section having a predetermined diameter, respectively, the securing screw opening and the locking screw opening being positioned relative to one another such that when both the securing screw and the locking screw have been extended through the securing screw opening and the locking screw opening, respectively, the locking screw head section will contact and apply an anti-rotational force against the securing screw head section;
wherein the securing screw and the locking screw are sheet metal screws having approximately the same size and shape.
