As such, the card socket 150 is provided with a connection terminal unit 160 (refer to FIG. 5) to electrically connect the external card and the circuit board.

According to an exemplary embodiment, connection terminals 145 are disposed in the circuit board 144, and through holes 146 corresponding thereto are formed in the circuit board region 144a. The connection terminal unit 160 extends from the card socket 150 to pass through the through holes 146 and to be connected to the connection terminals 145.

Hereinafter, the connection terminal unit 160 will be described in more detail. 4 is an enlarged view of the card socket of FIG. 3, and FIG. 5 is an exploded view of the card socket of FIG.

Referring to the drawings, the card socket 150 includes a housing chamber 151, a housing 152 and a cover 153.

The accommodation chamber 151 is formed to accommodate the external card 180 and is stacked with the circuit board 144 (see FIG. 3). An opening 151a is formed at one side of the accommodation chamber 151 to accommodate the exterior card 180. As shown, the card socket 150 is configured such that the opening 151a of the accommodation chamber 151 is disposed on the side of the battery seating portion 141.

The external card 180 is divided into a terminal portion 181 inserted into the card socket 150 and electrically connected to the circuit board 144, and a grab portion 182 in which the terminal portion 181 is not formed. The grab portion 182 becomes a portion that a user can hold by hand. The exterior card 180 is formed to be long in one direction, and the opening 151a is formed to correspond to the long edge of the exterior card 180.

The housing 151 is mounted on the circuit board area 144a, and a connection terminal 160 electrically connected to the external card 180 is mounted on one surface of the housing 151. As such, as the card socket 150 is mounted on the rear case 122, the card socket 150 is spaced apart from the surface on which the connection terminals 145 are disposed on the circuit board 144. At least one electronic device may be mounted on a portion of the surface where the connection terminals 145 of the circuit board 144 is disposed to be covered by the spaced card socket 150. As such, the circuit board 144 and the card socket 150 are spaced apart from each other, and as the electronic device is mounted in the space, the surface mounting area of the circuit board 144 is expanded.

Referring to the drawings, the connection terminal portion 160 includes an elastic deformation portion 161 and a mobile connection portion 162.

The elastic deformation part 161 is elastically deformed by the pressure of the external card 180 when the external card 180 is inserted into the accommodation chamber 151. For example, the elastic deformation portion 161 is mounted on one surface of the housing 151 and extends in a direction (direction toward the cover) protruding from one surface so that the end portion is pressed by the outer card 180.

The movable connection part 162 is formed to be interlocked with the elastic deformation part 161 and moved to connect with the connection terminals 145 of the circuit board 144 by the elastic deformation of the elastic deformation part 161.

In this case, poor contact between the protruding portion and the terminal portion 181 may be prevented by the elastic restoring force of the elastic deformation portion 161.

In response to the bending deformation of the elastic deformation part 161, the movable connection part 162 penetrates the through hole 154 and the through hole 146 and is pressed in the direction toward the circuit board 144. Through this, the mobile connection unit 162 is in contact with the connection terminal 145 of the circuit board 144, and eventually the external card 180 and the circuit board 144 are electrically connected.

As such, the structure in which the card socket 140 is not surface-mounted on the circuit board 144 eliminates the need for soldering connection between the circuit board 144 and the card socket 140 and further enhances the beautiful appearance of the terminal case. Appearance can be implemented.

When the external card is inserted, one end of the mobile connecting portion 262 is pressed, and the mobile connecting portion 262 slides along the through hole 254. At this time, the movable connecting portion 262 passes through the insertion hole 247 and is connected to the connection terminal 245 of the circuit board 244, and the elastic deformation portion 261 exerts an elastic force on the movable connecting portion 262. When the external card is extracted, the mobile connector 262 is restored to its original position by the elastic force.

In addition, some of the embodiments may be combined with the embodiments shown with reference to FIGS. 3 to 5. For example, in the embodiment shown with reference to FIGS. 3 to 5, an insertion hole 247 may be formed instead of the through hole 146 (see FIG. 4), in which case the card socket protrudes from one surface of the terminal case. The height can be reduced.
