Description

Battery pack connection device of watch type telephone {CONTACT DEVICE FOR BATTERY PACK IN WATCH-TYPE RADIOTELEPHONE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable wireless terminal, and more particularly, to a battery pack connection device for a watch-type radiotelephone that can be worn on a wrist.

Typically, portable small terminals refer to portable devices such as HHP, CT-2, cellular phones, digital phones, PCS phones and the like. Such a portable device performs a communication function while performing wireless communication with a base station.

At present, such portable terminals are becoming more and more miniaturized and lighter in electronic components, and the first generation of bar-type mobile phones has become commonplace, and the second generation of flip-type mobile phones has become commonplace. Nowadays, flip-type and third-generation folder-type mobile phones are coexisting. In the future, folder-type mobile phones or more compact portable terminals will come into the spotlight.

A typical bar-type mobile phone has a body element, an antenna unit installed on an upper part of the main body, an earpiece including a speaker under the antenna unit, and an LCD unit installed under the earpiece. (LCD unit), a key pad including a plurality of number keys and function keys located below the LCD unit, and a microphone unit located below the keypad.

A typical flip type mobile phone (e.g., disclosed in US Pat. No. 5,629,979) comprises a main body, a flip, and a hinge device connecting the main body and the flip. An antenna device is installed at the top of the body of the flip type mobile phone, and an ear piece including a speaker is located below the antenna device, and an LCD is mounted below the ear piece, and a plurality of number keys and numbers are located below the LCD part. A key pad including a key is installed, and a microphone device is mounted below the keypad. If necessary, a microphone device may be installed on the flip element.

A typical folder type mobile phone (e.g., disclosed in US Pat. No. 5,628,089) comprises a main body, a folder, and a hinge device for opening and closing the main body and folders to a call angle. The conventional folder type mobile phone is provided with an antenna device on the top of the main body, a keypad including a plurality of number keys and numeric keys is installed below the antenna device, and a microphone device is installed below the keypad. The folder opened and closed by the hinge device in the main body is located in the ear piece including the speaker, the LCD is mounted below the ear piece. At this time, the hinge device for opening and closing the folder from the main body to the call angle performs a function of connecting the folder and the main body mechanically and electrically.

In such a bar type, flip type and folder type mobile phones, flip type or folder type mobile phones with excellent sound sensitivity have become common in flip type or folder type mobile phones.

The reason why such flip type mobile phones and folder type mobile phones are becoming common is as follows.

This is because the flip type mobile phone protects a plurality of keys in a call standby mode to protect a plurality of keys and prevents malfunction of the keys, and collects sounds by performing a role of a reflector of a call during a call mode. Moreover, the flip type mobile phone can install a microphone device on the flip element, which is advantageous in miniaturizing the main body.

This is because the folder-type mobile phone protects the keypad mounted on the main body in the call waiting mode to protect the keypad mounted on the main body, and prevents the malfunction of the keys. Moreover, the folder type mobile phone is very advantageous for miniaturizing the main body since the speaker device or the LCD may be installed in the folder.

At this time, the current mobile phone is a trend of miniaturization, but the mobile phone is limited in miniaturization for ensuring the distance between the user's ear and the mouth. That is, in the case of a portable terminal, the distance between the talker (part where the microphone device is installed) and the receiver (part of the earpiece including the speaker) should be 14 cm or more. Therefore, flip-type or folder-type mobile phones will be miniaturized while maintaining communication distance.

However, the conventional bar type, flip type, or folder type mobile phones have a limitation in miniaturization. Therefore, there is a problem that the portability of the mobile phone falls. It was common for users to carry their phones in their pockets or carry them in a separate bag or hand. The portability of such a conventional mobile phone is very high, and a problem arises in that the mobile phone cannot be used if a drop or an impact is applied during use by a careless mistake.

Moreover, the conventional mobile phone has a problem that the structure is very vulnerable to waterproof.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a battery pack connection device for a watch type telephone which is installed to be detachable in a sliding manner from the bottom of the main body.
