Hinged device for mobile phone with power supply means {DEVICE FOR OPENING AND SHUTTING FLIP COVER IN FLIP-TYPE PORTABLE TELEPHONE}

The present invention relates to a flip-type mobile phone, and more particularly to a hinge device for opening and closing the flip cover, and more particularly to a hinge device having a power supply means.

In general, mobile phones are widely used mobile devices including cellular phones, digital phones, CT-2, PCS phones, and such mobile phones are of a bar type and a flip type. Currently, the bar type and the flip type coexist, and the flip type mobile phone is becoming more and more common. The flip type mobile phone is widely used because a flip cover installed in the main body protects a plurality of keys and performs a negative reflector role. In addition, flip-type mobile phones are advantageous for miniaturization of a device set.

Moreover, the folder-type mobile phones, which are most advantageous for miniaturization, are becoming more and more common. In the future, flip-type or folder-type phones will become commonplace. Such flip-type or folder-type mobile phones will continue to be miniaturized and lightweight while maintaining a communication distance (usually about 14 cm) between the speaker and the microphone.

In the above-described flip type mobile phone, a hinge device is essentially installed in order to implement a call angle of the flip cover. Accordingly, the flip type mobile phone is composed of a main body, a flip cover, and a hinge device for mechanically connecting the flip cover to the main body.

No. 5,697,124, a hinge device is installed at the lower end of the main body, and the flip cover is coupled to the hinge device to implement a call angle of the flip cover.

However, the above-described conventional flip cover merely performs a simple cover role. In other words, the speaker cannot be mounted on the flip cover, and since the hinge device does not have a power supply means, only the flip cover is opened and closed. The conventional flip cover simply serves as a reflector for protecting the keys of the main body or collecting the microphone sounds.

In addition, the conventional hinge device is disadvantageous in miniaturization of the product due to the excessive number of the conveying element, and even if the microphone is mounted on the flip cover, it is difficult to electrically connect to the printed circuit board of the main body. The excessive amount of the component increases the occurrence of defective factors, and the excessive factor of the assembly process has become a major factor in the decrease in productivity.

All of these problems have limitations on the miniaturization and lightening of products, and have led to the recent trend toward miniaturization of products.

Therefore, the present invention proposes a hinge device that is advantageous for miniaturization of a product while maintaining the communication distance between the transmitter and the receiver.
