  • Publication number: 20100087074
    Abstract: An electronic card connector (100) defining a receiving space (10) and includes an insulative housing (1), a number of contacts (2) and an ejecting mechanism (3) retained in the insulative housing (1), and a metal shell (5). The ejecting mechanism (3) includes a slider (31) and a latch strip (34) fixed on the slider (31). The latch strip (34) has a retention portion (341) retained on the slider (31) and a spring arm (343) extending sidewardly. The spring arm (343) has an arm portion (3431) and a resistive portion (3432) extending sidewardly. The resistive portion (3432) is offset from the arm portion (3431) along a width direction. The metal shell (5) has a limiting wall (55) extending into the receiving space (10) for protecting the spring arm (343) from being resisted overly by an electronic card. The limiting wall (55) defines a plane which is located between that of the resistive portion (3432) and arm portion (3431).

  • Publication number: 20090253280
    Abstract: An electrical card connector (100) for insertion of an electrical card (200) includes an insulative housing (1) defining a receiving space (14) for insertion of the electrical card. The insulative housing includes a bottom wall (10) and a side wall (12) extending from a lateral side of the bottom wall. A number of terminals (3) are retained in the insulative housing and extend into the receiving space for electrical connection to the electrical card. An ejecting mechanism (4) includes a slider (41) movable along card-insertion or card-withdraw directions, a coil spring (42) for urging the slider, and a connecting rod (43) having an one-end bend portion retained in the insulative housing and an other-end bend potion movable in a heart-shaped cam groove (412) formed in the slider. The side wall of the insulative housing has a protrusion (125) extending from an upper side thereof to abut downwardly against the slider (41).

  • Publication number: 20090246993
    Abstract: A card connector (100) for connecting an electronic card (200) includes an insulative housing (1), a plurality of contacts (2) retained in the insulative housing (1), and an ejector (3). The insulative housing (1) defines a receiving space (10) for receiving the electronic card (200). The ejector (3) includes a slider (31) retained in the insulative housing (1), a spring (32) and a pole (33) mounted between the slider (31) and a rear end of the insulative housing (1). The slider (31) has an inner side wall (310), an inclined face (3100) angled with respect to the inner side wall (3100) to abut against the electronic card (200), and a protrusion (3102) projecting inwardly from the inner side wall (310) to resist the electronic card (200) sideward. Thereby the electronic card (200) can be inserted in or ejected from the card connector (100) smoothly.

  • Publication number: 20090221168
    Abstract: A memory card connector includes an insulative housing, a plurality of contacts retained in the insulative housing, a card eject mechanism and metal shell attached to the insulative housing. The insulative housing defines a card receiving cavity for insertion of a memory card. The card eject mechanism includes a slider moveable along card-insertion or card-withdraw directions and a locking member fixed to the slider. The locking member includes a protrusion which forms a sideward dimple. The metal shell includes a top wall covering the card receiving cavity. The top wall defines a slit for receiving the protrusion. An arced surface of the dimple is driven to abut against an inner side of the slit in order to reduce friction therebetween.
