Description

PORTABLE TERMINAL HAVING STABLE CONTACT STRUCTURE USING MAGNETIC}

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 cover battery 100 shown in FIGS. 1 and 2. It is. The radiation pattern of the antenna is formed on the housing of the portable terminal, and the radiation pattern may be printed, deposited, plated, laser direct structuring (LDS), or MID (Molded Interconnect Device) on the housing of the portable terminal formed of ceramic. Intenna form as shown in Figure 1 is a radiation pattern is molded in the housing of the portable terminal by inserting the antenna integrally to the housing of the portable terminal using insert injection to reduce the volume of the product to meet the consumer's slimmer needs It can be made thinner. In addition, in the form of the intenna 110 of FIG. 1, since a radiation pattern is present inside the housing, a short circuit problem, etc., generated when the radiation pattern is exposed to the outside can be solved. Can strengthen. There is a point when designing a portable terminal including the form of such an antenna 110. First, since the antenna 110 is built in the case of the portable terminal, the fastening force between the cover battery 100 in which the antenna of the portable terminal is embedded and a housing area (not shown) including a connection part connecting the printed circuit board are included. In addition, when the cover battery 100 and the housing rear (not shown) are combined, it is necessary to form a stable contact between the connection portion of the printed circuit board of the portable terminal and the antenna.

2 is a cross-sectional view showing an example of the integrated antenna integrated portable terminal of the Korean Patent No. 10-0910161. Feeding unit 220 in contact with the radiation pattern 210 and the connecting portion (not shown) of the printed circuit board is included.

Forming a stable contact between the feeding unit 220 and the antenna 230 is a point in designing a portable terminal.

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.
