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 the 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 includes a base body and a card mounting space disposed on the base body for slidingly mounting a wafer card, the card mounting space having an opening for inserting a wafer card; The card retaining device further includes a release device slidably mounted on the base body in a direction perpendicular to a sliding direction of the wafer card and located in front of the opening for locking or unlocking the wafer card to the card Installed space.

Compared with the prior art, the wafer card holding device has a simple structure, and the wafer card is easily installed and disassembled by installing a releasing device in front of the card mounting space of the substrate, and the wafer card is installed and replaced at the same time. The process is much simpler and easier to operate.

The two clamping portions 40 are oppositely disposed on opposite sides of the card connector 31 on the circuit board 30, and together with the card connector 31 and the circuit board 30, a card mounting space 33 is defined. The space 33 has an opening (not shown) for inserting the wafer card 90 and facing the strip groove 12 so that the wafer card 90 is housed in the card mounting space 33.

The release device 50 is a block slider having a substantially "Z" shape in cross section, and is slidably mounted on the base 10 in a direction perpendicular to the sliding direction of the wafer card 90. The groove 12 is located at a position in front of the opening for locking or unlocking the wafer card 90 in the card installation space 33. The release device 50 includes a mounting end 51, a control end 53 disposed opposite the mounting end 51, and a connecting portion 55 connecting the mounting end 51 and the control end 53. A circular mounting blind hole 57 is recessed on one side of the mounting end 51. The length of the connecting portion 55 is equivalent to the thickness of the guiding protrusion 17 so that when the guiding slider 50 is installed in the strip groove 12, the connecting portion 55 is clamped to the guiding convex portion. The block 17 is formed in a strip-shaped groove surrounded by the longitudinal side walls of the strip-shaped recess 12 and is slidable along the strip-shaped groove.

The elastic member 70 is a cylindrical coil spring that is mounted in the strip-shaped recess 12 of the base 10. One end of the elastic member 70 is sleeved on the circular protrusion 15 in the strip groove 12, and the other end is installed in the mounting blind hole 57 of the release device 50.
