Description
The present invention is a technique for maintaining a stable contact between the components included in the portable terminal. More specifically, the present invention relates to a technology for maintaining a stable contact between an antenna and a printed circuit board of a portable terminal and a technology for maintaining a stable contact between a housing rear of a mobile phone and a cover battery.
The antenna of the portable terminal serves to receive a radio frequency (RF) signal from the outside.
The external shape of the antenna has been developed from an external antenna to an internal antenna (Intenna) by slimming a portable terminal. In addition to the technology of attaching to the housing of the mobile phone in the form of a film, an in-mold antenna, which is embedded in the housing of a thin portable terminal having a thickness of about 1 mm, has been developed.
Equally important is the evolution of antenna performance. The essential function of an antenna is to accept an external signal. Factors that must be considered when designing the antenna should consider not only the structure and length of the antenna, but also the characteristics such as voltage standing wave ratio (VSWR), return loss (SAR) and specific absorption rate (SAR). What determines the performance of such an antenna affects the performance of the antenna as well as the antenna itself, as well as the printed circuit board (PCB) connected to the antenna. Because of the morphological evolution of the antenna, the antenna is inevitably close to the internal printed circuit board, so the interference with the RF component inside the portable terminal is increased and when the antenna is close to the LCD of the portable terminal, This is because performance may be degraded.
Factors that can also affect the performance of the antenna are not only the performance of each antenna and printed circuit board, but also the connection portion connecting the antenna and the printed circuit board. The connecting part transmits the signal received from the antenna to the printed circuit board and transmits the signal received from the printed circuit board to the antenna, which greatly affects the performance of the portable terminal.
This is because when the contact between the antenna and the printed circuit board is poor at the connection part, noise is generated and the noise may affect the signal transmitted from the printed circuit board. In addition, the electrical contact must be stably ensured to minimize the resistance at the contact point, and a uniform current can flow to improve the performance of the antenna to obtain reliable call quality.
Therefore, when the portable terminal is manufactured, it is a technical problem that exists in the design of the portable terminal to design the connection part of the portable terminal so that the contact between the printed circuit board and the antenna is not poor. Various connection members have been used as a technique for forming a conventional connection. The connection member with elastic force is fixed to the portable terminal, and the method of connecting the printed circuit board and the antenna of the portable terminal using the elastic force of the connection member was also used. The method of connecting the printed circuit board and the antenna using the POGO pin is used. It was also.
Conventionally, an antenna is embedded in a cover battery of a portable terminal through insert injection or metal printing using an Intenna technology for embedding the antenna in a case of the portable terminal. The antenna built into the cover battery using the conventional method may be connected to the rear case including the printed circuit board and the connecting portion by using a method of forming grooves and protrusions on the rear case and the cover battery and combining them.
Korean Patent No. 10-0910161 (Internal Antenna Integrated Portable Terminal Case and Manufacturing Method thereof) discloses a structure of an antenna of an internal antenna (110) type embedded in a
2 is a cross-sectional view showing an example of the integrated antenna integrated portable terminal of the Korean Patent No. 10-0910161.
Conventionally, in order to connect a printed circuit board and an antenna of a portable terminal, a connection member having an elastic force is connected. However, the elastic force decreases the elastic modulus while repeating a certain number of times of compression and relaxation, and thus does not guarantee stable electrical contact between the printed circuit board and the antenna of the portable terminal. Therefore, the stable performance of the two components of the portable terminal to ensure a minimum resistance and to allow a uniform current flow at the contact point of the connection between the two components can improve the performance of the antenna to obtain a reliable call quality.
When the rear case and the cover battery of the portable terminal are combined by the conventional method, if the fastening force of the rear case and the cover battery is reduced due to the frequent detachment of the cover battery, the connection between the antenna and the printed circuit board is the same as the above problem. This can be bad.
Accordingly, a first object of the present invention is to provide a portable terminal including a connecting portion for stably forming electrical contacts between a printed circuit board and an antenna of the portable terminal.
In addition, a second object of the present invention is to provide a portable terminal including a fastening portion connecting the cover battery and the printed circuit board of the portable terminal in order to stably form the electrical contact between the printed circuit board and the antenna.

The connection part may have the same curvature as the bend consisting of the first mounting part and the second mounting part of the housing rear so as to be located in the through hole of the housing rear of the portable terminal. The connection part may be made of a material having ductility so as to have the same curvature as the curvature formed of the first and second mounting parts of the housing. The permanent magnet may have the same shape as that of the groove formed in the connection portion, thereby widening the contact area. The antenna and the connecting portion may be formed of a ferromagnetic material. The antenna may be integrally formed on the cover battery by using at least one of insert molding, insert injection, and plating after metal printing. The antenna may be utilized for DMB, Bluetooth, and Wi-Fi.

The first fastening part is positioned to face the same number of permanent magnets as the at least one fastening insert to couple the housing and the cover battery, and the second fastening part forms a fastening structure with at least one groove and the groove. By using the same number of protrusions as the number of the grooves can be coupled to the housing and the cover battery.
As described above, according to an embodiment of the present invention, a portable terminal connecting a printed circuit board and an antenna using a permanent magnet and a portable terminal combining a housing and a cover battery using a permanent magnet according to an embodiment of the present invention may use a printed circuit using a permanent magnet. The connection between the board and the antenna prevents a poor contact between the printed circuit board and the antenna, and increases the coupling force between the cover battery and the housing by using a permanent magnet to fasten the cover battery with the antenna and the housing rear of the mobile phone. In addition, it is possible to prevent a poor contact between the printed circuit board and the antenna in the same manner as described above.
Therefore, by maintaining the electrically stable connection between the contacts to reduce the resistance of the contact so that less noise of the antenna is generated. In addition, by supplying a constant current to the contact point can improve the performance of the antenna through the improvement of the physical environment between the components of the portable terminal can bring a call quality improvement.
