Abstract

A customer-replaceable electronic cartridge is described which can be detached from or re-attached to a housing for electrical equipment. Attachment of the cartridge automatically connects it electrically to the equipment. The cartridge contains circuit elements, such as electronic cards, which it is desirable for the user to be able to replace without calling a service engineer. The cartridge is built with electrical socket connections for power and logic supplies, air ducts that interface with the host equipment air cooling system and electrical screening of internal circuits from external interference. Hook-on hinges allow the (Image Omitted) cartridges to accurately engage on housing pivots and to swing into the closed position, locking by means of snap connectors at the side, top or back of a housing.

Replaceable Card Cartridge for Equipment Enclosure

A customer-replaceable electronic cartridge is described which can be detached from or re-attached to a housing for electrical equipment. Attachment of the cartridge automatically connects it electrically to the equipment. The cartridge contains circuit elements, such as electronic cards, which it is desirable for the user to be able to replace without calling a service engineer.

cartridges to accurately engage on housing pivots and to swing into the closed position, locking by means of snap connectors at the side, top or back of a housing. One cartridge can constitute the complete side or top of a small equipment enclosure. Cartridge 2 contains electronic components 3, such as a CPU card, volatile or read-only storage and items liable to require alteration during the life of the equipment. The construction material used for the cartridge must be able to protect the interior from damage by dirt and handling as well as screening the contents from electrostatic external disturbance when in use. Such a material could be a high impact resistant polycarbonate with a deposited metallized internal screen. The compliant connector detail is shown in Fig. 2. A connector body 5 locates and snaps onto the housing lugs 7 by means of spigots 8 but remains floating and able to align as pegs 9 mate onto the card connector 4 and slide into guidance holes 10 engaging electrically with internal...
