Description

Electrical connector

The present invention relates to an electrical connector, and more particularly to a subscriber identity module (SIM) card connector.

A subscriber identification module or a subscriber identity module typically appears in a removable card type that securely stores a service-subscriber key, where the user The service key is used to identify users of mobile communication devices (eg, mobile phones or laptops). Generally, a SIM card includes a unique serial number, an internationally unique number of the mobile user (IMSI), a security authentication and a ciphering information, and Temporary information related to the local area network, service access list accessed by the user, personal identification number (PIN), and PIN unlock key.

The SIM card is connected to the mobile communication device via the SIM connector. A wide variety of SIM connectors have been developed to connect SIM cards to different types of mobile communication devices. FIG. 1 shows a SIM connector disclosed in US Patent Application Publication No. 2010/0055985 A1.

The receiving member 70, wherein the terminal module 20 has a plurality of terminals 21 received therein; the metal mask 30 is mounted on the insulating housing 10 to partially cover the insulating housing 10 and defines a card receiving space.

The card receiving member 70 carries the electronic card inserted into the card housing space. The switching element 60 is received in the insulative housing 10 and includes a movable member 601 and a fixing member 602. When the card receiving member 70 is not inserted, the fixing member 602 abuts against the movable member 601. The movable member 601 has an arcuate portion that protrudes into the card receiving space, and the card receiving member 70 can be pressed against the curved portion to separate the movable member 601 from the fixing member 602 and trigger a card insertion signal.

The electronic card connector 100 has a disadvantage. Since the movable member 601 is moved by the card receiving member 70, even if the card receiving member 70 does not carry the SIM card, the card insertion signal is triggered to generate an unnecessary read/write operation.

In view of the aforementioned lack of conventional electrical connectors, a new electrical connector is provided.
