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. 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 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 two latching mechanisms; the base body includes a mounting surface, and the two latching mechanisms are oppositely disposed on the mounting surface of the base body and form a chip for receiving a chip together with the mounting surface The card holder accommodating device further includes an elastic member protruding from the mounting surface of the base body and partially received in the card accommodating space to elastically resist the wafer card to the card accommodating space Set the space.

Compared with the prior art, the wafer card holding device has a simple structure, and the mounting and dismounting of the chip card is easily realized by providing an elastic member on one of the stopper walls of the wafer card holding device, and at the same time, the wafer card is The installation and replacement process is simpler and easier to operate.

1 is a perspective view of a preferred embodiment of a wafer card holding device of the present invention; and FIG. 2 is a schematic view showing the operation of mounting a wafer card into or removing a wafer card from the wafer card holding device of FIG. 3 is a perspective view showing the wafer card completely mounted in the wafer card holding device shown in FIG. 1.

A preferred embodiment of the present invention discloses a wafer card holding device suitable for use in mobile power Portable electronic devices such as personal digital assistants (PDAs). In the present embodiment, the wafer card holding device is described by taking a mobile phone (not shown) as an example.

Referring to FIG. 1 , a wafer card holding device 30 according to a preferred embodiment of the present invention includes a base 31 , two latching mechanisms 33 , and an elastic member 37 . The base body 31 has a substantially rectangular plate shape, which may be a housing of a mobile phone. The base 31 includes a mounting surface 311.

The two holding mechanisms 33 are disposed on the mounting surface 311 of the base 31, and together with the mounting surface 311, form a card accommodating space 35 for accommodating a wafer card 50. In this embodiment, each of the latching mechanisms 33 includes a stop wall 331 and two anti-drop blocks 335. The stop wall 331 has a substantially U-shaped wall shape and protrudes from the base body 31 in a facing orientation. On the mounting surface 311. The two ends of each of the stop walls 331 extend away from the side of the mounting surface 311 toward the card accommodating space 35 to form a tamper-proof block 335. The distance between the detachment preventing block 335 and the mounting surface 311 is The wafer card 50 has a comparable thickness. A chip card connector 40 is disposed on the mounting surface 311 of the card accommodating space 35 for electrically connecting to the chip card 50 mounted in the card accommodating space 35.

The elastic member 37 is an arcuate tongue-shaped elastic piece protruding from the end of the retaining wall 331 of the latching mechanism 33 and partially received in the card accommodating space 35 to elasticize the wafer card 50. Resist in the card accommodation space 35.

Referring to FIG. 2 and FIG. 3, when the wafer card 50 is mounted, one side of the wafer card 50 is inserted into the elastic member 37 toward the end of the elastic member 37, and is biased toward the elastic member 37. On the wafer card 50, the wafer card 50 is pushed to press the elastic member 37 to be elastically deformed until the wafer card 50 is completely received in the card housing space 35. After the wafer card 50 is installed in the card accommodating space 35, the elastic member 37 elastically resists the wafer card 50 to prevent the wafer card 50 from being loosened. The anti-deblocking block 335 is stuck to the crystal Above the four corners of the card 50, the wafer card 50 is prevented from coming out. When the wafer card 50 needs to be taken out, the force is applied toward the elastic member 37, and the elastic member 37 is pushed to move away from the card accommodating space 35, so that the wafer card 50 is moved toward the elastic member 37 until the wafer card is moved. The wafer card 50 can be taken out by pulling up the side of the elastic member 37 away from the side of the elastic member 37 with a finger.

It can be understood that the holding mechanism 33 can be integrally formed with the base 31 by means of stamping, casting, injection molding or the like.

It can be understood that the holding mechanism 33 is not limited to the "U" shaped stop wall 331 in the embodiment, and may be formed by two stop walls of a substantially "L" shape.

It can be understood that the elastic member 37 can be directly protruded from the mounting surface of the base 31 and partially received in the card accommodating space 35.

The wafer card holding device 30 has a simple structure, and the mounting and dismounting of the wafer card 50 is easily realized by providing an elastic member 37 on a stopper wall 331, thereby simplifying the process of installing and replacing the wafer card 50. Easy to operate.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
