A memory card connector includes a pair of guide frames and a connector head. The ejection mechanism of the memory card connector comprises a top cover plate that has a pair of arms each extending from one end thereof for engaging one corresponding pair of guide frames. The top cover plate has a pair of guide rings each located at one end thereof and a guide sliding space formed between the guide rings. A rocker lever has a pivotal hole approximately at the center, and a guide containing opening is formed at one end. A push-out plate has a pair of sliding recessions and a pair of card pushing edges, wherein each pushing edge is located adjacent one end thereof and a guide rod formed between the sliding recession. A push rod has a rocker lever engaging slot at one end thereof. The pivotal hole of the rocker lever receives one of the guide ring shaft formed by the guide rings. The guide containing opening receives the guide rod of the push-out plate. Each pair of guide rings is slidably received in one corresponding pair of sliding recessions of the push-out plate. The guide rod of the push-out plate is further received in the guide sliding space of the top cover plate. The distal end of the rocker lever opposing the end thereof having the guide containing opening, is received in the rocker lever engaging slot of the push rod.

Memory card connector with card ejection mechanism

A grounding strip for a memory card connector is disclosed to provide the electrical grounding of the memory card inserted. The memory card connector comprises a guide frame having a pair of guiding slots. Each of the guiding slots has formed therein a pair of notches and a receiving slot. The grounding strip comprises a substantially elongated body. A curved contact portion is formed approximate one end of the elongated body that arises generally above the surface of the elongated body. An end portion is formed at the remote end beyond the contact portion of the elongated body. A first pair of bent portions are respectively located at the opposing sides of the elongated body and extending away from the surface of the elongated body, and each of the first bent portions has formed thereon a latching means. When the grounding strip is assembled to the designated location on the guide frame of the memory card connector, the end portion would be received in the receiving slot of the guiding slot. Each of the first pair of bent portions would be inserted into a corresponding one of the first pair of notches, and the latching means of the first pair of bent portions would latch with the corresponding configuration inside the corresponding notch. Firm attachment of the grounding strip to the guide frame of the memory card connector can therefore be secured.
