Description

Electronic card connector

The present invention relates to an electronic card connector, and more particularly to an electronic card connector having a switch terminal.

With the development of mobile storage technology, electronic cards used as extended storage are rapidly developing, for example, there are different types of expansion cards such as smart cards, SD cards, and CF cards. Among them, SD card or CF card and other large-sized cards are usually used in large-sized electronic devices such as desktop computers or notebook computers, and such large cards can be supported by hot-swappable USB card readers and electronic devices. The device is connected. When the electronic card is connected through the USB card reader, when the electronic card is removed, the electronic device usually displays a prompt message for the user to confirm whether the electronic card is to be removed.

Small cards such as smart cards are not used in small electronic devices such as mobile phones or digital cameras, and there is not enough space for connection using a USB card reader. Moreover, the aforementioned large card may also be directly inserted into the electronic card connector in the electronic device without using the USB adapter, and the smart card and the electronic card directly connected to the electronic card connector in the electronic device are returned. The prompt information cannot be displayed in the electronic device for the user to confirm whether the electronic card is actually to be removed. For example, in a mobile phone, when there is a number being edited or a text message is not saved, if the user forgets that the foregoing content is not stored, the smart card is directly removed from the mobile phone, and the smart card is directly removed without prompting, and the user edits The number or text message may be lost.

In order to avoid the above problems, the present invention proposes a new type of electronic card connector to make up for its deficiencies.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electronic card connector that can generate a time delay when a card is ejected for the user to confirm the card ejecting action.

In order to achieve the above object, an electronic card connector includes an insulative housing, a signal terminal assembled in the insulative housing, a card ejecting mechanism assembled on one side of the insulative housing, and an electronic card receiving space covered in the insulating body. The shielding case further includes a first switch terminal sliding along with the card ejecting mechanism, a second switch terminal assembled in the insulating body, and a third switch terminal. During the card retracting process, the first switch terminal moves with the card ejecting mechanism And moving to a second state in which the second switch terminal and the third switch terminal are disconnected by the first state of turning on the second switch terminal and the third switch terminal, and moving to the second state when the electronic card exits the final state The third state of the switch terminal and the third switch terminal.

Compared with the prior art, the electronic card connector of the present invention includes three switch terminals. When the electronic card is fully inserted, the first switch terminal is in the first state of turning on the second switch terminal and the third switch terminal, and the card is retracted. When the first switch terminal moves with the card ejecting mechanism, by the first state of turning on the second switch terminal and the third switch terminal, moving to the second state of disconnecting the second switch terminal and the third switch terminal, and in the electronic card The final state of the exit moves to a third state in which the second switch terminal and the third conductive terminal are re-conducted. Then, in the second state, the user can confirm whether it is determined to perform the card withdrawal operation to prevent the stored data from being lost.
