Abstract

This article describes a mechanism for safety grounding a pluggable feature without using a screw or similar type of fastener. (Image Omitted) Conventionally, for safety grounding a removable part of a system, screws or similar types of fasteners are used to secure two metal parts (base portion and removable portion) together. The safety grounding mechanism disclosed herein is integrated in a pluggable array of modules called shrouds. A shroud houses a printed circuit (PC) board that is required to be safety grounded. This mechanism alleviates the need for using a screw or other fastening means when plugging a shroud into the system. Referring to the exploded perspective view of Fig. 1, the mechanism of this disclosure is shown utilizing a connector specifically designed for safety grounding pluggable shrouds.

Pluggable Safety Grounding Mechanism for a Printed Circuit

This article describes a mechanism for safety grounding a pluggable feature without using a screw or similar type of fastener.

(Image Omitted)

Conventionally, for safety grounding a removable part of a system, screws or similar types of fasteners are used to secure two metal parts (base portion and removable portion) together. The safety grounding mechanism disclosed herein is integrated in a pluggable array of modules called shrouds. A shroud houses a printed circuit (PC) board that is required to be safety grounded. This mechanism alleviates the need for using a screw or other fastening means when plugging a shroud into the system. Referring to the exploded perspective view of Fig. 1, the mechanism of this disclosure is shown utilizing a connector specifically designed for safety grounding pluggable shrouds. The male portions of the connector are mounted to the system frame where they are connected to the system ground. As can be seen, the connector has nine male portions (one for each shroud slot) that bus all of the pluggable shroud grounds together. The female connector is shown in exploded perspective in Fig. 2. It consists of a card bracket, spring clip and rivet that fastens these parts to make the assembly shown in Fig. 3. The assembly is attached to a PC board. The PC board is placed into a protective shroud which forms the pluggable assembly (see Fig. 4). Fig. 5 shows a cross section of the sys...
