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 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 comprising a base body and a card accommodating chamber formed on the base body for mounting a wafer card; the card accommodating chamber is recessed on a surface of the base body, and correspondingly Forming a bottom wall, two opposite longitudinal side walls and two opposite lateral side walls; the wafer card holding device further comprises an elastic body mounted on a lateral side wall of the card accommodating chamber The device is housed in the card accommodating chamber to elastically mount the wafer card in the card accommodating chamber and provide an elastic thrust when the wafer card is taken out.

Compared with the prior art, the wafer card holding device has a simple structure, and the wafer card is easily mounted and disassembled by the provision of an elastic body on the lateral side wall of the card receiving chamber of the substrate, and the wafer card is simultaneously obtained. The installation and replacement process is simpler and easier to operate.

A preferred embodiment of the present invention discloses a wafer card holding device suitable for use in a portable electronic device such as a mobile phone or a personal digital assistant (PDA). 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 , the wafer card holding device 30 includes a base 31 , a card accommodating chamber 32 formed on the base 31 , a release member 35 , an elastic body 37 and at least one retaining portion 39 . The release member 35 and the elastic body 37 are respectively disposed opposite to opposite end positions of the card accommodating chamber 32, The retaining portion 32 is disposed above the card accommodating chamber 32.

The base body 31 has a substantially rectangular plate shape, and may be a bottom wall of a casing mounted on a circuit board (not shown) in the mobile phone.

The card accommodating chamber 32 has a substantially rectangular groove shape, and is recessed downwardly on a surface 311 of the base body 31, and correspondingly forms a bottom wall 321 , two longitudinal walls 322 , 323 disposed opposite to each other, and another Two lateral walls 326, 327 are disposed opposite each other. The card accommodating chamber 32 can accommodate a wafer card 50 which is an accommodating space formed on the base 31 and has a shape corresponding to the wafer card 50. A rectangular through hole 325 is defined in the bottom wall 321 for receiving a chip card connector (not shown). The lateral side wall 326 is disposed as a slanting wall connecting the bottom wall 321 and the surface 311 to facilitate the removal of the wafer card mounted in the card accommodating chamber 32. A substantially U-shaped notch 328 is formed in a direction substantially parallel to the two longitudinal side walls 322, 323 at a substantially central position of the lateral side wall 326, thereby correspondingly forming the substantially rectangular tongue disposed toward the other lateral side wall 327. a release member 35. When the release member 35 is urged in a direction perpendicular to the surface 311 of the base 31, the release member 35 is elastically movable up and down in a direction perpendicular to the surface 311 of the base 31. A substantially central position of the other lateral side wall 327 is recessed away from the lateral side wall 326 in a direction away from the lateral side wall 326 to form a rectangular cutout 329 communicating with the rectangular through hole 325 and the card receiving chamber 32 for loading The elastic body 37 is provided.

The elastic body 37 is disposed in the rectangular cutout 329 and partially received in the card accommodating chamber 32 to elastically mount the wafer card 50 in the card accommodating chamber 32 and provided when the wafer card 50 is taken out. An elastic thrust. The elastic body 37 is a relatively reciprocatingly bent or elastically deformable elastic member. In this embodiment, the elastic body 37 is a substantially "W" shaped compression spring, which is integrally formed in the same. Within the slit 329.

The retaining portion 39 is substantially in the shape of a rectangular bump, and is disposed on the surface 311 of the base 31 adjacent to the card receiving chamber 32 and partially extends above the card receiving chamber 32 for holding Place The wafer card 50 mounted in the card accommodating chamber 32 is prevented from coming off the card accommodating chamber 32. In the present embodiment, the retaining portions 39 are two, which are respectively disposed on the surface 311 of the base 31 adjacent to the two longitudinal side walls 322, 323 of the card receiving chamber 32, and are partially disposed at the position The card accommodating chamber 32 is above.

Referring to FIG. 2, a perspective view of a wafer card 50 mounted in the wafer card holding device 30 is shown. When the wafer card 50 is mounted, one end of the wafer card 50 is slid along the beveled end of the lateral side wall 326 of the wafer card holding device 30, and the wafer card 50 is pushed against the release member during the sliding process. 35. At the same time, the release member 35 is pressed downward until the wafer card 50 is completely mounted in the card accommodating chamber 32 and elastically abuts against the elastic body 37 at the end of the lateral side wall 327. The elastic body 37 is compressed, and the other end of the wafer card 50 is correspondingly abutted against the release member 35. The retaining portion 39 is located above the wafer card 50 to prevent the wafer card 50 from being detached from the card housing chamber 32.

Referring to FIG. 3 together, when the wafer card 50 needs to be taken out, the release member 35 is pressed downward, so that the slope of the release member 35 toward the surface 311 side is lower than the lower surface of the wafer card 50. The wafer card 50 is moved toward the lateral side wall 326 by the elastic force of the elastic body 37, and slides along the slope of the lateral side wall 326 to take out the wafer card 50.

It can be understood that the elastic body 37 can also be a sponge, an elastic plastic body, a leaf spring or a compression spring or the like directly mounted on the lateral side wall 327.
