With such a configuration, the dimension of the case 11 in the thickness direction can be shortened, and the mobile phone 10 can be thinned.

  The circuit board 20 includes a sub board 22 and a card connector 30 disposed on the sub board 22. The card connector 30 accommodates the SIM card 60 and is used for electrical connection between the SIM card 60 and the mobile phone 10, and includes a housing portion 31 and a tray portion 32. The card connector 30 is mounted on the sub board 22. Specifically, the card connector 30 is disposed on the sub-board 22, and the housing portion 31 is fixed to the sub-board 22 using solder, anisotropic conductive resin, or the like. Thereby, the card connector 30 is fixed to the sub-board 22.

  As shown in FIGS. 4 and 5, the housing portion 31 is formed of a predetermined insulating material and has a substantially box shape with one end (front side in the drawing) and the other end (rear side in the drawing) opened. Inside the tray portion 32 is slidable in the direction from one end to the other end or in the direction from the other end to the other end (indicated by an arrow A in FIG. 4, this direction is hereinafter referred to as a slide direction). It is stored.

  As shown in FIG. 5, the housing portion 31 is provided with a connection terminal 311 that is electrically connected to an electrode provided on the SIM card 60 at a predetermined position on the bottom surface side. On the other hand, a round hole 312 is formed in one surface (upper surface in FIG. 5) of the housing portion 31 at a site corresponding to the installation position of the connection terminal 3111.

  In the housing portion 31 having such a configuration, the tray portion 32 on which the SIM card 60 is mounted is inserted and set to a predetermined position inside the housing portion 31, and the SIM card 60 and the tray portion 32 are placed in the housing portion 31. When accommodated, the SIM card 60 and the connection terminal 311 are electrically connected, and the user can use the mobile phone 10.

  As shown in FIG. 6, the tray portion 32 is formed in a substantially plate shape with a predetermined insulating material, and a first surface 321 facing the SIM card 60 and a second surface opposite to the first surface 321. Surface 322. In particular, the tray portion 32 has a U-shaped one end portion (base end portion) in the sliding direction in order to ensure electrical connection between the electrode on the SIM (or UIM) card 60 side and the connection terminal 311 of the housing portion 31. A notched opening 323 is provided. That is, the opening 323 passes between the first surface 321 and the second surface 322. Thus, when the SIM card 60 is set at a predetermined position, the electrodes of the SIM (or UIM) card 60 can contact and conduct with the connection terminal 311 of the housing portion 31.

Tray unit 32, the other end portion of the sliding direction at the (tip), the first convex portion P ₁ is provided on the second surface 322.

Further, as shown in FIG. 3, the first convex portion P <b> ₁ is arranged in a state where the side portion 331 on the sub substrate side faces the end surface (tip surface) 221 of the sub substrate 22. Furthermore, the first convex portion _{P 1} is opposed to the battery 50. That is, in the thickness direction of the mobile terminal device 10, the first protrusion P ₁ and the battery 50 are disposed so as to overlap each other, and the end of the first protrusion P _{1 on} the upper case 40 side is the battery 50 battery. It is on the upper case 40 side from the surface on the cover 11B side.

By the way, when the mobile phone 10 is accidentally dropped, the battery 50 is displaced and comes into contact with the tray unit 32, and a force acts to push up the tray unit 32. Further, the SIM card 60 and the card connector 30 are shocked. Is transmitted. Under this structure, the force transmitted from the battery 50 can be distributed to the opposing sub-substrate 22 through the first convex portion P ₁ and the end surface (tip surface) 221, and the impact transmitted to the SIM card 60 and the card connector 30 can be dispersed. It can be reduced.

Further, the tray unit 32, at the tip, and a second projecting portion P ₂ which projects along a direction from the second surface 322 to first surface 321. Accordingly, the second convex portion P ₂ is the first convex portion P ₁ protrudes along the opposite direction. Furthermore, the tray part 32 includes a stopper part S formed thick in the width direction of the tray part 32 (the depth direction in FIG. 3) in order to stop the tray part 32 itself at a predetermined position with respect to the housing part 31. (See FIGS. 4 and 6). The stopper portion S has a surface facing the rising portion 31, and the housing portion 31 has a surface facing the stopper portion S. The stopper portion S and the housing portion 31 are arranged so that their surfaces abut. With this arrangement, the stopper portion S prevents the tray portion 32 from entering the housing portion 31 beyond a predetermined distance. In this embodiment, the distance D ₁ from the first convex portion P ₁ to the end surface (tip surface) 221 of the sub-board 22 is the distance D from the stopper portion S to the end portion (tip portion) 311 of the housing portion 31. _The configuration is smaller than ₂ (that is, D ₁ <D ₂ ). In such a configuration, a gap is always ensured between the stopper portion S and the housing portion 31 even when the first convex portion P ₁ hits the end surface 221 of the sub-board 22. Therefore, even when the tray part 32 is pushed in, the collision of the tray part 32 against the housing part 31 can be prevented.

Further, in the present embodiment constitutes a first projecting portion P ₁ and the second end surface of the convex portion P ₂ in the same plane (smooth surface without steps). That is, the first convex portion P ₁ and the second convex portion P ₂ have the same surface at the tip of the tray portion 32. Typically, the same surface is a flat surface, but it is not limited to a flat surface and may be any surface as long as it is a smooth surface without a step. This makes it difficult to hook the pawl such the fingers between the first convex portion P ₁ and the second projecting portion P _2. Therefore, it becomes difficult to remove the SIM card 60 by forcibly lifting and pulling out the tray portion 32 with the battery 50 set.
