The present invention relates to a hinge module of a folding portable wireless terminal which is installed so that a predetermined sub body is opened and closed at a predetermined angle on the main body. In particular, the present invention is configured to perform a smooth hinge operation while applying a conductor for reducing SAR. It relates to a hinge module of a portable wireless terminal.

As portable wireless terminals become more and more popular, terminals of various functions and designs are appearing. In addition, the terminal is becoming smaller and lighter and smaller, and at the same time, the diversity of its functions is being highlighted. Therefore, in order to satisfy the needs of the consumers as described above, there is an emphasis on reducing the volume of the terminal to the maximum while maintaining or improving the function.

On the other hand, while maximizing the variety of functions, the terminal is becoming lighter and shorter and more and more convenient for the user, the terminal manufacturers are racing to solve the inconvenience caused when the user uses the terminal.

Recently, a portable wireless terminal is a folder type consisting of a main body, which is a main body rather than a bar type, and a sub body, which is a folder installed to be opened and closed at a predetermined angle by a predetermined hinge module on the main body. type or flip-up type terminals are becoming mainstream. The reason for using such a folder type terminal is that the sub-body (including a flip cover or a folder) connected to the main body protects a number of key buttons formed on the main body to prevent malfunction of the device and plays a negative reflector role during a call. Because it collects the notes. Moreover, in the folder type terminal, the wide LCD module can be separately mounted in the folder portion, which is advantageous in miniaturizing the product and in implementing a variety of functions.

Typically, the folder type terminal is equipped with a hinge module for opening and closing the sub body at a predetermined angle on the main body. The hinge module not only designates a predetermined opening / closing angle of the sub body, but also serves to store the predetermined elastic force when folded so that the folder does not open arbitrarily.

On the other hand, due to the rapid dissemination of portable wireless terminals and the development of various electronic industries, devices for shielding electromagnetic waves or reducing the absorption rate of electromagnetic waves, which are harmful to the human body, have gradually emerged. In particular, the Specific Absorption Rate (SAR) is used in human body protection standards as a measure of the amount of electromagnetic waves absorbed by the human body (head).

In general, the portable terminal is used in close contact with the human body (head), the electromagnetic wave absorption rate is affected by the near field (near field) of radio waves emitted from the antenna device of the terminal. Therefore, it will be said that there is a close relationship with the transmission power, the antenna characteristics, and the shape of the apparatus of the radio terminal to be used.

As described above, a method of reducing the electromagnetic wave absorption rate may include using a directional antenna device or attaching a separate conductor plate to shield the radio wave or inserting a radio wave absorber (conductive paint) or forming a component of the terminal using a conductive material. Power supply with the RF board of the main body to play the role of ground.

Therefore, in the related art, the hinge module is made of a conductive metal and fed with the RF board of the main body. For example, the hinge shaft, the hinge cam, the hinge spring, and the hinge housing constituting the hinge module are formed of metal, and have been fed to one side or the other side of the hinge module.

However, as described above, when the entire hinge module is formed of metal, it is difficult to assemble, and friction occurs between the metals during the hinge operation, and when used for a long time, all the lubricant is consumed and noise is generated. Occurs and causes a problem that the terminal is polluted.

The present invention has been made to solve the above problems is to provide a hinge module of a portable wireless terminal is configured so that noise does not occur even for a long time use.

Another object of the present invention is to form a component of the hinge module of a synthetic resin material to minimize the occurrence of debris by friction and at the same time to reduce the electromagnetic wave absorption rate of the portable wireless terminal having a conductive member fed to the main board of the main body To provide a hinge module.
