A predetermined PCB 13 is provided in the case 11, 12 of the terminal 10. For reference, the detailed configuration of the terminal 10 can be understood from a known configuration, and thus detailed descriptions and explanations thereof will be omitted. In the present embodiment, the PCB 13 is provided between the two cases 11 and 12. However, the present invention is not limited thereto, and the PCB 13 may be provided between the case 11 and the case 12 And may be practically variously modified. The cases 11 and 12 may refer not only to the outer case of the terminal 10, but also to the case and internal components constituting the inside of the terminal 10.

The shell housing 25 is provided inside the terminal 10 and has a connection terminal 24 for electrically connecting the terminal housing 10 to the terminal 10. The shell housing 25 is formed such that the tray 22 is slidably insertable. For example, the shell housing 25 has a form in which a part or the whole of the tray 22 is received, and as shown in the figure, one side is provided so that the tray 22 can be inserted into the shell housing 25 Open. Further, the shell housing 25 may be formed such that the cover portion 251 and the base portion 252 are coupled to each other. However, the shell housing 25 is not limited thereto, and it is also possible that the cover portion 251 and the base portion 252 are integrally formed. In addition, the shell housing 25 may have various forms in which the tray 22 can be inserted.

The connection terminal 24 is provided inside the shell housing 25 and is mounted on the PCB 13 to electrically connect the PCB 13 and the card 21. [ The connection terminal 24 can be formed to protrude toward the card 21 so as to be in contact with a contact portion (not shown) of the card 21 when the card 21 is inserted. The connection terminal 24 has a predetermined elasticity so as to maintain a stable contact state with the card 21 and fix the card 21. [ However, the present invention is not limited to the drawings, and the shape, arrangement, and the like of the connection terminal 24 can be changed substantially in various ways.

A mold part 23 for fixing the connection terminal 24 can be formed. For example, the molded portion 23 may be formed by inserting the connection terminal 24. [ Here, the shape of the molded part 23 is not limited to the drawings, and may be substantially varied.

The tray 22 is formed to be insertable into the shell housing 25 in a state in which the card 21 is mounted. The tray 22 is formed with a card insertion portion 221 on which the card 21 is mounted and a flange 223 formed on the rear side. In order to separate the tray 22, a key groove 225 may be formed on one side of the flange 223. The keyway 225 described in this embodiment may be a hole formed through the flange 223 or a groove that does not penetrate through the flange 223.

Here, a separate separating member 14 may be provided for separating the tray 22 from the shell housing 25, which is coupled to the tray 22. For example, the tray 22 is formed with a key groove 225 having a slit-like shape elongated in the horizontal direction, and the separating member 14 has a latching protrusion 141 which is inserted into the key groove 225 at one end to be fastened It may have a formed lever shape. The separating member 14 is stored at one side of the terminal 10 or at a place designated by the user and is connected to the tray 22 as needed to separate the tray 22 and the card 21 from the terminal 10 . The separating member 14 has a simple shape in which a predetermined engaging projection 141 is formed at one end, and is formed to have a small size for easy storage. Here, the shape of the separating member 14 is not limited to the drawings, and may have substantially various shapes that can be selectively separated and separated from the tray 22.

The flange 223 is formed at a position rearward relative to the direction in which the tray 22 is inserted into the shell housing 25, that is, at a position where the user faces the tray 22. Further, the flange 223 extends outwardly to have a thickness greater than the thickness of the tray 22. Here, the thickness of the card 21 is thin, so that the thickness of the card insertion portion 221 is also formed to be about the thickness of the card 21. However, by forming the flange 223 thicker than the card insertion portion 221 to a predetermined thickness, the key groove 225 can be formed and the separating member 14 can be easily attached to the tray 22. [ Further, even if the thickness of the tray 22 is made thin by forming the flange 223, the strength of the entire tray 22 can be secured to a predetermined size or more. The flange 223 also serves as a stopper for regulating the insertion of the tray 22 into the shell housing 25 when the tray 22 is inserted into the shell housing 25. [

The card insertion portion 221 is formed as a groove or an opening formed at a predetermined depth on the surface of the tray 22. Here, the card insertion portion 221 keeps the card 21 stably mounted on the tray 22, and when the card 21 is mounted, the card 21 is prevented from protruding from other portions of the tray 22 The entire height of the tray 22 can be reduced. An opening is formed in the card insertion portion 221 so that the card 21 can be coupled to the connection terminal 24 while being inserted into the tray 22.

The tray 22 may have a guide rib 222 for supporting the lower surface of the card 21 in the card insertion portion 221 when the card insertion portion 221 is formed as an opening. However, the present invention is not limited to the drawings, and the shape and size of the guide ribs 222 can be substantially varied. Although the card insertion portion 221 and the guide rib 222 are separately described in the present embodiment, the card insertion portion 221 and the guide rib 222 may be integrally formed without distinguishing the card insertion portion 221 from the guide rib 222 .

When inserting the tray 22 into the shell housing 25, guide means for guiding movement may be formed. For example, a slide guide 224 formed at a predetermined height along the direction in which the tray 22 is inserted into the shell housing 25 may be formed on the lower surface of the tray 22. Here, the slide guides 224 may be formed on both side ends of the tray 22, and may have two flanges or ribs formed parallel to each other. A guide groove 253 may be formed on the inner side surface of the base portion 252 of the shell housing 25 so as to be engaged with the slide guide 224 thus formed. However, the present invention is not limited to the drawings, and the shapes of the slide guide 224 and the guide groove 253 can be substantially varied and can be omitted.

Although not shown in the drawing, a sealing member (not shown) for waterproofing the inside of the tray 22 may be provided at one side of the terminal 10, the tray 22, and the shell housing 25.

The separating member 14 may be omitted and the tray 22 may be attached to the shell housing 25 in the tray 22 itself, Alternatively, an ejecting unit may be provided for separating from the terminal 10.
