Circuit card insertion and removal system

Abstract

A system (22) for removably connecting a circuit card, such as an extension card (54), to an electronic device, comprises a sliding component (28) adapted to support the circuit card (54) and having a guiding edge (32) configured to be slidably inserted in a channel (26) disposed adjacent a connector (20) of the electronic device so as to position the card mating edge (56) in register with the connector (20). A lever (40) is provided for lowering the mating edge 56 of the extension card (54) until suitable connection is made between the card connector and the connector (20). Advantages of the present invention include the fact that the system allows for ergonomic insertion and removal of extension cards without the need for manual dexterity on behalf of the user.

Description

RELATED APPLICATIONS

This Because the lever 40 is not constrained against rotation by any part of the chassis 10 it follows that he lever 40 may be actuated with the sliding component anywhere along the path of travel (in the direction of the arrow 62) of the sliding component 28 so as to displace the auxiliary plate 34 and card 54 in the direction of the downwardly located arrow as seen in FIGS. 5 to 7. In other words, the lever 40 may be rotated to displace the auxiliary plate 34 and any attached card independently of the position of the sliding component along its path of travel within chassis 10.

The specific configuration of the lever 40 reduces the force required for proper connection. In order to remove the sliding component 28 from the chassis 10, the above-mentioned sequential steps merely need to be reversed.

An optional abutment prong (not shown) may be disposed within the chassis 10 to ensure proper positioning of the sliding component 28 therein.

Advantages of the present invention include the fact that the system allows for ergonomic insertion and removal of extension cards without the need for manual dexterity on behalf of the user. Furthermore, the present system ensures proper alignment and sound connection between the extension card 54 and the associated socket 20. Also, the system reduces the risk of damaging either the electronic device or the extension card 54 during installation or removal, and conforms to conventional forms of manufacturing so as to provide a system that is economically feasible, long-lasting and relatively trouble-free in operation. Moreover, the present system can be readily adapted to various computer configurations.

The sliding component 28 is preferably made of aluminum and acts as a shield for protecting the extension card 54.

Finally, it should be understood that although the present system has been described as being used in the field of computer and, more particularly, of personal computers, it could be used in other fields including fields wherein electronic circuitry is to be removably connected to an interface or substrate.
