  • Patent number: 7341465
    Abstract: An electrical card connector (100) for electrically connecting with an electrical card (6) includes an insulator (1) defining a receiving space (14), a number of contacts (2) retained in the insulator, a pair of latching portions (45) and a shield (5) covering the insulator (1). The shield includes a pair of fingers (512) corresponding to the latching portions (45). Each finger defines a cantilever (5121) extending into the receiving space (14) and a latch member (5122) for engaging with the latching portion (45). When a complementary card is inserted into the connector, it abuts against the cantilever (5121) and lifts the latch member (5122) outwardly. The latch member (5122) disengages from the latching portion (45). The card is further inserted in the connector and electrically connects the contacts thereof.

  • Patent number: 7214075
    Abstract: A portable memory device (1) includes a memory unit, a USB mating port (20) electrically connecting with the memory unit, a protective case (30) detachably mated with the USB mating port and a plastic waterproof member (32) secured in the case. The plastic waterproof member is pressed against a periphery (213) of the USB mating port to seal a gap between the USB mating port and the case. The USB mating port is protected in the case form water penetration. Moreover, the plastic waterproof member imposes a force rising from plastic deformation of the plastic waterproof member on the USB mating port. Therefore, the USB mating port and the case is firmly engaged with each other.
