Generic "D" Shell Bracket

This article describes a generic input/output I/O bracket design for personal computers (PCs). It can be used for option cards with "D" shell I/O connectors and for option cards with daughter cards that have the same size "D" shell connectors.

Conventionally, additional tooling and unique P/Ns for brackets were required for each daughter card I/O application using a "D" shell connector.

Referring to Fig. 1, an I/O bracket opening for a "D" shell I/O connector is typically configured to match the shape of the "D" itself. This provides the minimum gap or clearance around each "D" shell which provides the maximum electromagnetic interference (EMI) shielding. The mechanical architecture allows for a daughter card 2 as shown in Fig. 2 to be .50" from the mother (standard) card 3 position. Therefore, the centerline of the "D" shell connector of the daughter card is coincident with the centerline of the "D" shell connector on the mother card.

The bracket disclosed herein is shown in Fig. 3. It was designed by superimposing the daughter card application over the mother card. This shows that with only minimal material 4 (Fig. 1) removal from the mother card bracket both left-hand "D" and right-hand "D" configurations can be accommodated.
