Abstract
A ground electrode is disposed between a card-side connector and an upper panel, movably forward or backward in the card insertion direction, the ground electrode including protuberances projecting through the protuberance receiving holes of the upper panel. The ground electrode is energized to move forward in the card insertion direction by means of a torsion spring such that, when the PC card is inserted into a 16-bit card slot corresponding to a predetermined high driving voltage, the protuberances in the protuberance receiving holes are moved backward in the card insertion direction against the spring force of the torsion spring.
Claims13
A personal computer (PC) card for electrical and mechanical communication with a personal computer card slot, the PC card comprising:
- a frame having forward and rearward ends and sides defining an interior volume, the forward and rearward ends defining forward and rearward directions corresponding to respective card insertion and removal directions into and out of the personal computer card slot;
- a circuit board disposed within the volume and including a ground;
- a connector disposed at the forward end of the frame which provides an electrical interface between the circuit board and the PC card slot;
- and
- a ground electrode coupled to the ground of the circuit board and disposed on the connector, the ground electrode being movable in the forward and rearward directions with respect to the frame such that it may make contact with a receiving ground electrode of the PC card slot.
