Abstract
Abstract A PC card connector comprises a header connector, a shielding cover and an ejection mechanism. The ejection mechanism includes ejection means and actuation means. The ejection means is adapted to eject a fully inserted PC card from the header connector. The actuation means includes an elongate base and an elongate rod received in the base. A slider is moveably mounted between the base and the rod. The rod defines a recess for receiving the slider and forms an inclined inner surface for downwardly pressing against the slider thereby preventing the slider from becoming disengaged from the base. The ejection mechanism further includes a jacketing member adapted to receive the rod and the base of the actuation means. The jacketing member forms a number of latches along side edges thereof for engaging with a side wall of the shielding cover thereby securing the actuation means thereto.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
375 words
A PC card connector for providing electrical connection between a PC card and a circuit board, comprising: a header connector including an insulative housing and a plurality of terminals retained in the housing; a shielding cover attached to a side of the header connector for shielding the PC card connector and an inserted PC card; ejection means assembled to the shielding cover and being adapted to eject the fully inserted PC card from the header connector; a bracket secured to a lateral edge of the shielding cover and including a central wall, an upper side wall and a lower side wall; an elongate base received in the bracket and defining a cam channel; an elongate rod movably attached to the base and received in the bracket, the rod defining a groove and a recess in a bottom surface thereof, the groove being in communication with the recess; a spring provided between the base and the rod; a slider being movably received in the groove and including a pin slidably received in the cam channel, the slider having a leading end proximate the pin and a rear end opposite the leading end, the slider being adapted to push one end of the ejection means to eject the PC card; and an inclined inner surface formed in the recess, wherein at a first position where the rod is about to be manually pushed in the bracket and compress the spring, an inner end of the groove presses against the rear end of the slider, and wherein at a second position where the rod is about to be projected out of the bracket by the spring, the inclined surface presses against the leading end of the slider; wherein the slider includes a convex portion, and the inclined surface urges an edge of the convex portion with a force perpendicular to the inclined surface wherein a horizontal component of the force outwardly pushes the slider and a vertical component of the force downwardly presses against the edge of the convex portion of the slider; wherein a leaf spring is provided between the rod and the slider, the leaf spring including one end fixed in an inner top wall of the groove and another end downwardly pressing against the slider.
