Technical Examples
  1. An electrical card connector (1) includes an insulative housing (10) enclosed by a metallic shield (28). The housing (10) defines a receiving space (18) with first and second sets of contacts (22, 24) disposed in the housing (10) and communicating with the receiving space (18). A protection door (40) is pivotally mounted to the housing (10) in an entrance opening (19) blocking the receiving space (18) from an exterior. A moveable locking member (60) releasably locks the protection door (40). The protection door (40) defines a cutout to leave a small entrance opening (46) to allow a small sized card (300) to be guidably and snugly inserted into the receiving space (18) wherein the protection door (40) is equipped with another small pivotal anti-dust door (56) to cover that small entrance opening (46). Therefore, the card connector (1) can mutually exclusively receive the large sized card (200) and the small sized card (300) guidably and reliably.
