Opening and Closing Mechanism of Card Enclosing Cartridge Box

This invention provides a cartridge box for a circuit card. The cartri is equipped with side doors which open automatically when it is connected to another cartridge.

Fig. 1 shows an assembly structure of the cartridge. A circuit card 2 with a number of electronic components, such as IC modules 10 and electric connectors 9 and 12, is enclosed in the cartridge which comprises an upper cover 1, a lower cover 3, openings 8, 11, and side doors 4. These doors are biased to a closed position by means of spring 6.

When a plurality of the cartridges are stacked, circuit cards 2 are electrically connected to adjacent ones with connectors 9 and 12.

Fig. 2 shows a cross sectional view of stacked cartridges. When the cartridge A is connected to another cartridge B, boss 5' on the lower cover 3' pushes projection 7 of the side door 4 of cartridge A against the bias by spring 6 so that side door 4 opens. Cartridge C shows the condition before stacking. Thus, electronic components are provided with air flow for cooling.

The cartridge including the circuit card may be sent to customers by mail for replacement or extension.
