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 chip card holding device includes a base body and a card mounting portion formed on the base body for slidingly mounting a wafer card, the card mounting portion having an opening for inserting a wafer card; The card retaining device further includes a release member slidably mounted on the base body and respectively positionable in front of or on one side of the opening for locking or unlocking the wafer card in the card mounting portion.

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

A preferred embodiment of the wafer card holding device of the present invention will be described as an example of a mobile phone (not shown).

Referring to FIG. 1 , a wafer card holding device 100 includes a base 10 , a circuit board 30 , two clamping portions 40 , and a release member 50 . The base body 10 has a substantially rectangular frame shape, which may be a casing of a mobile phone. The base body 10 has a side wall 12 which is recessed downwardly at a position near one end thereof. A substantially rectangular strip-shaped recess 121 defines an outer sidewall 123 and an inner sidewall 125 opposite the outer sidewall 123 at an end portion of the sidewall 12. A strip-shaped guide groove 13 is formed on the outer surface of the outer side wall 123 in a direction parallel to the strip-shaped groove 121. The length of the guide groove 13 is equivalent to the length of the strip-shaped groove 121. A first positioning portion 15 and a second positioning portion 17 are recessed in the guiding groove 13 for positioning the release member 50 mounted on the sidewall 12 of the base 10. In the embodiment, the first positioning portion 15 and the second positioning portion 17 are respectively spaced apart from the two hemispherical limiting grooves recessed at the two ends of the guiding groove 13 .

The circuit board 30 has a substantially rectangular plate shape and is disposed on the base body 10 adjacent to the strip-shaped recess 121 of the base body 10. A card connector 31 is mounted on one side of the circuit board 30 adjacent to the strip-shaped recess 121.

The two clamping portions 40 are opposite to the two sides of the card connector 31 mounted on the circuit board 30, and together with the card connector 31 and the circuit board 30, form a card mounting portion 33, the card The mounting portion 33 has an opening (not shown) for inserting the wafer card 90 and facing the strip-shaped recess 121 so that the wafer card 90 is housed in the card mounting portion 33.

Referring to FIG. 2, the release member 50 is a substantially U-shaped block slider having a substantially U-shaped cross section, and is slidably mounted on the side wall of the base 10 in a direction perpendicular to the sliding direction of the wafer card 90. The outer side wall 123 is located at a position in front of the opening for latching or unlocking the wafer card 90 into the card mounting portion 33. The release member 50 includes an engaging wall 51 and a mounting wall 53 spaced apart from the engaging wall 51. The engaging wall 51 and the mounting wall 53 define a substantially rectangular groove-shaped assembly space 55. . The distance between the engaging wall 51 and the mounting wall 53 is equivalent to the thickness of the outer wall 123 of the base 10. The thickness of the mounting wall 53 is equivalent to the width of the strip groove 121 so that The release member 50 is slidably mounted on the outer side wall 123, and the mounting wall 53 of the release member 50 is slidably mounted in the strip-shaped recess 121. The inner surface of the engaging wall 51 facing the mounting wall 53 corresponds to the first positioning portion 15 or the first in the guiding groove 13 The two positioning portions 17 are respectively provided with two spherical protrusions 52 so as to be slidable along the guiding groove 13 when the releasing member 50 is mounted on the side wall 12 of the base body 10, and are respectively positioned at the first of the guiding grooves 13 The positioning portion 15 and the second positioning portion 17 are located.
