Description

Wafer card holding device

The present invention relates to a holding device for accommodating and holding a wafer card, and more particularly to a wafer card holding device for a portable electronic device.

With the rapid development of the communication industry, the use of various portable electronic devices such as mobile phones and personal digital assistants (PDAs) has become more and more popular. As the functions of these portable electronic device products become increasingly diversified, more and more wafer cards for storing memories are applied to such portable devices, such as an SD card (Secure Digital Memory Card) and a CF card ( Compact Flash Card), a Subscriber Identification Module Card, etc. The chip card is a plastic card equipped with an IC chip, which has the functions of recording a personal user number and an address book, and can be used by a plurality of users by replacing the chip card.

Conventional wafer cards are generally housed in a card slot of a portable electronic device. When the chip card is received in the card slot, the integrated circuit on the chip card is connected to the circuit board of the portable electronic device by a connector. When the wafer card needs to be replaced, the user directly presses the exposed portion of the wafer card with a finger and drags the card card outside, and the wafer card is driven by the friction between the user's finger and the wafer card. The user's finger moves until the wafer card slides out of the card slot.

However, in actual use, since the portion of the wafer card exposed to the card slot is generally small, it is difficult to directly press the exposed portion; some types of wafer cards are even accommodated in the card slot. Therefore, it is difficult for the user to drive the wafer card to slide out of the card slot by directly pressing the wafer card.

In view of the above drawbacks, it is necessary to provide a wafer card holding device that can easily replace a wafer card and can effectively accommodate and hold the wafer card.

A wafer card holding device includes a body and a cover body, wherein the body is provided with a receiving chamber; the cover body has a top wall, and includes a hinge end and a fastening end opposite to the hinge end. The cover body is rotatably hinged to the body and fastened to the body by the fastening end thereof; the cover body further includes an elastic portion disposed on the hinge end of the top wall, the elastic portion elastically resisting The cover body is slidably mounted on the body by the elastic portion and elastically fastened to the body.

Compared with the prior art, the wafer card holding device has a simple structure, the chip card is mounted on the cover body, and is rotatably mounted on the body with the cover body, and an elastic portion is disposed by the hinge end of the cover body. Correspondingly, a fastening portion is disposed on the other side of the cover body, which facilitates the installation and removal of the wafer card, and at the same time, the process of installing and replacing the wafer card is simpler and easier to operate.
