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), SIM card (Subscriber Identification Module Card), etc. Among them, the SIM card is a plastic card equipped with an IC chip, which has functions of recording a personal user number and an address book, and can be used by a plurality of users by replacing the SIM 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 wafer card is generally exposed to the outside of the card slot, the portion is generally small. It is more difficult to directly press the exposed part; some models of the chip card are even placed 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 base body and a card mounting portion disposed on the base body for mounting a wafer card, the card mounting portion having an opening for inserting a wafer card; the wafer card The holding device further includes a top cover and a release member, the top cover is detachably mounted on the base body and located above the card mounting portion, the top cover is formed through a through hole; the release member is slidably The strip is inserted into the strip-shaped through hole of the top cover for pushing the wafer card out of the card mounting space.

Compared with the prior art, the wafer card holding device has a simple structure, and the wafer card is easily mounted and disassembled by a release member slidably mounted on the top cover, and the wafer card is installed at the same time. And the replacement process is easier and easier to operate.
