Description

Built-in antenna connection structure of portable radio device {STRUCTURE FOR CONTACTING INTERNAL ANTENNA OF PORTABLE RADIO APPARATUS}

The present invention relates to a built-in antenna mounted on a portable wireless device, and more particularly, to a built-in antenna connection structure of a portable wireless device that can improve the reliability and productivity of the built-in antenna for a portable wireless device, and can reduce the manufacturing cost.

The antenna converts electrical signals expressed by voltage and current and electromagnetic waves expressed by electric and magnetic fields. The antenna is mounted externally or internally to a portable radio device to receive electromagnetic waves from the air and detected by the radio device. It converts into electrical signal which can be done, and converts electrical signal of wireless device into electromagnetic wave and transmits it to the air.

The antenna of such a wireless device may be classified into an external type mounted on the outside of the wireless device and an internal type mounted on the inside according to the mounting position. In particular, in the case of the internal antenna mounted on the inside of the wireless device, the antenna main body is located inside the wireless device. Since it is mounted on, there are relatively many restrictions compared to the external antenna in the manufacturing process.

The antenna should transmit / receive electromagnetic waves while maintaining the electrical connection with the internal circuit of the wireless device. Especially, since the internal antenna is installed in a limited space inside the wireless device, the antenna may have a stable electrical connection with the main PCB provided inside the wireless device. It is very important to maintain.

However, it is very difficult to match the connection point with the connection point provided in the main PCB due to the characteristics of the built-in antenna installed in the limited space inside the wireless device.

In addition, since the built-in antenna is completely embedded in the wireless device, once it is installed inside the wireless device and the assembly is completed, proper failure processing may not be performed for the defective contact or the unstable connection.

In addition, conventionally, by using a method such as soldering to connect the built-in antenna with the main PCB inside the wireless device, there is a problem that is vulnerable to external impact after welding.

Accordingly, an object of the present invention for solving the above problems is to provide a built-in antenna connection structure of a portable wireless device that can maintain the connection between the built-in antenna and the main PCB of the wireless device in the built-in antenna of the portable wireless device. .

In addition, another object of the present invention is to provide a built-in antenna connection structure of a portable wireless device that can freely change the connection position of the connection point when connected to the main PCB in the built-in antenna of the portable wireless device.

In addition, another object of the present invention is to provide a built-in antenna connection structure of a portable wireless device that can improve the manufacturing productivity by simplifying the assembly process in the connection method of the built-in antenna of the portable wireless device.

In addition, another object of the present invention is to provide a built-in antenna connection structure of a portable wireless device that can maintain a strong connection force to the impact, not by soldering in the connection method of the built-in antenna of the portable wireless device.
