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 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 comprising a base body and a bottom plate, the base body having an outer surface, an inner surface opposite to the outer surface, and a side perpendicular to the outer surface and the inner surface; the inner surface is recessed a strip-shaped recess penetrating through the side surface, and forming two opposite parallel guiding sidewalls on the base body; the bottom plate is mounted on the inner surface of the base body, and together with the strip-shaped recesses, forms a receiving cavity for mounting the wafer card The wafer card holding device further includes a pushing device including a main body and a pushing wall; the pushing device is slidably mounted in the strip groove of the base body, and the strip groove is on the side A rectangular opening is formed in the upper portion to facilitate insertion and clamping of the wafer card from the rectangular opening between the main body and the bottom wall, and push the push wall to push the wafer card out by the sliding push device.

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