Chip card locking device and portable electronic device

The invention relates to a wafer card locking device and a portable electronic device having the same.

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. By replacing the SIM card, the same portable electronic device can be used by a plurality of users.

The conventional chip card is generally detachably mounted and housed in a card slot or a card accommodating portion of the portable electronic device, and the chip card is connected to the bottom wall of the card slot or the card accommodating portion by a connector. The circuit board in the portable electronic device establishes an electrical connection. In order to prevent the wafer card from coming out of the card slot or the card accommodating portion during use (ie, the battery is in a power supply state), a locking device is usually disposed at the opening position of the card slot or the card accommodating portion. To prevent the wafer card from coming off.

However, the structure of the conventional locking device is generally complicated and occupies a large space in the portable device. Moreover, since the locking device usually does not have an assembly and control relationship with the battery in the portable device, the wafer card is actually used. When the battery is still in the power supply state, it is easy to be directly taken out, thereby causing serious damage to the portable electronic device.

In view of the above drawbacks, it is necessary to provide a wafer card latching device which is simple in structure and can effectively protect the wafer card from being erroneously taken out by the battery card in a battery supply state.

It is also necessary to provide a portable electronic device having the wafer card locking device.

A wafer card locking device is mounted on a portable electronic device; the wafer card locking device includes a main body, a holding portion and an elastic locking member, the holding portion is disposed on the main body, The wafer card locking device is mounted on the portable electronic device; the elastic locking member is bent and formed on the clamping portion of the main body to elastically lock the wafer mounted in the portable electronic device. card.

A portable electronic device includes a body, a battery and a wafer card, the body including a battery mounting portion and a wafer card mounting portion disposed adjacent thereto for correspondingly mounting the battery and the wafer The portable electronic device further includes a wafer card locking device detachably mounted on the body; the wafer card locking device includes a resilient locking member, and the elastic locking member is received in the card In the battery mounting portion, the battery mounted in the battery mounting portion is pushed to lock the wafer into the wafer card mounting portion.

Compared with the prior art, the wafer card locking device has a simple structure and is easy to operate, and is mounted on the body of the portable electronic device adjacent to the opening portion of the chip card mounting portion, and is mounted on the battery. The battery in the unit controls the wafer card locking device, which effectively ensures that the battery is detached and the user is in a non-power supply state when the wafer card is taken out, thereby easily protecting the wafer card and the portable electronic device.
