Abstract

A card holder for large scale integration (LSI) cards provides a means for installing and retaining LSI cards on LSI boards. The holder protects the card and simplifies the installation of the card in a system frame. A locking device on the card holder fastens the card holder onto the system frame after it is installed. In Fig. 1, card holder consists of two molded plastic parts, a card holding frame 2 and a card cover 4. Frame 2 has guide rails 5 and 6 which guide the holder into the system frame when the card holder is installed. The inside surface of these rails contains slots (only slot 7 is visible) to receive and hold card 8 in position in frame 2. With card 8 in slots 7 in frame 2, cover 4 is attached to frame 2 by "T" fasteners 9. Fasteners 9 fit into mating receivers 10 on frame 2.

Card Holder and Lock

A card holder for large scale integration (LSI) cards provides a means for installing and retaining LSI cards on LSI boards. The holder protects the card and simplifies the installation of the card in a system frame. A locking device on the card holder fastens the card holder onto the system frame after it is installed. In Fig. 1, card holder consists of two molded plastic parts, a card holding frame 2 and a card cover 4. Frame 2 has guide rails 5 and 6 which guide the holder into the system frame when the card holder is installed. The inside surface of these rails contains slots (only slot 7 is visible) to receive and hold card 8 in position in frame 2. With card 8 in slots 7 in frame 2, cover 4 is attached to frame 2 by "T" fasteners 9. Fasteners 9 fit into mating receivers 10 on frame 2. When the cover is in place, a user may easily handle a card mounted in frame 2 without actually touching the card. This helps to protect the card from electrical shock and physical damage from handling. Once the card is installed in the holder, the holder may be fastened into the system frame, as shown in Fig. 2A. Fig. 2B is an edge view of the card holder showing the card lock. Lock mount 12 is molded as part of card-holding frame 2. Lock 14 has a handle 15, engaging member 16 and a shaft 17. Shaft 17 is inserted through a hole in lock mount 12. The hole compresses shaft 17 until it is fully inserted. Then the shaft can expand to hold lock 14 in lock moun...
