  • Patent number: 7686639
    Abstract: An electrical card connector (100) includes an insulating housing (10), a metal shield (30) defining a plurality of channels (110, 142, 141), a terminal module (20) with a plurality of contacts (21) received therein and a clip. The metal shield shields over the insulating housing for defining a card receiving space. The clip includes a pair of first elastic pieces (40) and a second elastic piece (50). The first elastic piece forms a first contact portion (42) and a second contact portion (41). The first contact portion protrudes into the card receiving space for connecting with an inserted card (70). The second elastic piece forms a flexible arm (51) interfering with the second contact portion.
