The protrusion 324 protrudes from one surface of the lower housing 320 and is coupled to the hinge hole 421. The protrusion 324 serves as a rotation axis that forms a center of rotation when the second lever 420 is rotated by the force from the first lever 410. The mechanism by which the second lever 420 rotates and the tray 500 is pulled out will be described in more detail below with reference to FIG.

Although the upper and lower housings 310 and 320 are physically separated from each other in the above description, the upper and lower housings 310 and 320 may be vertically separated from each other for convenience of explanation. The upper housing 301 and the lower housing 302 are coupled to each other to form an opening on one side. It is also possible that the upper housing 310 and the lower housing 320 are integrally formed.

A tight contact portion is formed between the lever and the housing 300 to prevent noise generated when the lever and the housing collide with each other. For example, the projecting portion 414 of the first lever 410 and the projecting wall 322 can be combined with each other to form a tight contact portion. Hereinafter, the structure of the adhered portion will be described in detail.

FIG. 5A is a cross-sectional view of the socket module 200 taken along line VV in FIG. 3, FIG. 5B is a cross-sectional view showing another embodiment of the socket module 200 of FIG. 6B is a cross-sectional view taken along line VI-VI of FIG. 5B. FIG.

Referring to FIGS. 5A and 6A, protrusions 314 protruding toward the body portion 411 of the first lever are formed on one side of the housing 300.

That is, according to the present embodiment, the contact portion for closely contacting the housing 300 with the first lever includes the protrusion 314 formed on one surface of the housing 300.

The protrusion 314 protrudes from the lower housing 320 and the protrusion 314 protrudes from the lower housing 320. The protrusion 314 protrudes from the upper housing 310 and the lower housing 320, As shown in FIG.

A lever for pulling out the tray 500 is mounted on the housing 300, and a gap is formed between the lever and the housing 300 to secure a lever mounting space. That is, in the conventional case, a gap of about 0.06 mm is formed between the upper housing 301 and the lever 303 by design, and the lever flows when the mobile terminal is used by the gap. Unnecessary noise is generated when the terminal is used due to the flow of the lever, and such noise may be uncomfortable to the user.

The protrusion 314 can prevent the lever from flowing when the lever is not used while securing a space for mounting the lever. In other words, since the protrusion is formed on the housing 300, the lever 300 prevents the housing 300 from being hammered when the terminal vibrates.

The protrusion 314 may be formed of an elastic member. The resilient member contacts the body portion 411 of the first lever to elastically compress the resilient member and applies restoring force to the body portion 411.

The elastic member may be made of rubber or plastic, or may be formed so that the band-shaped metal plate bends and has an elastic force.

According to another embodiment of the present invention, a guide groove 415 may be formed on one surface of the body part 411. The guide groove 415 is extended in the advancing direction DR1 of the body portion 411 and is formed to engage with the protrusion 314. [

The projection 314 and the guide groove 415 are engaged with each other and move relative to each other. Since the protrusion 314 engages with the guide groove 415, the first lever does not move in the direction perpendicular to the protruding direction (DR2 in Fig. 4) as well as the protruding direction of the protrusion.

According to another embodiment of the present invention, the protrusion 314 includes a first extension extending from the upper housing 310 toward the lower housing 320, and a second extension extending from the one end of the first extension to the width direction of the housing, And may include an extension. For example, the projection may protrude in a T-shape (not shown). The guide groove is formed to engage with the projection. That is, the body portion may have a T-shaped groove extending along the longitudinal direction of the lever.

The upper housing 310 and the lower housing 320 may have protrusions facing each other. That is, the body portion 411 is prevented from vertically moving by the second protrusion contacting the opposite surface of the first protrusion contacting the one surface of the body portion 411.

First and second guide grooves may be formed on the upper surface and the lower surface of the body portion 411 to be engaged with the first and second projections, respectively.

The protrusions are engaged with the guide grooves to prevent the body portion 411 from flowing in the left-right direction.

Referring to FIGS. 5B and 6B, a protrusion 416 protruding to contact with the housing 300 may be formed on the body part 411. That is, the first lever and the housing are closely contacted by the protrusion 416 formed on the body portion 411.

The protrusion 416 may be formed of an elastic member. The elastic member elastically compresses against the body portion 411 and applies a restoring force to the body portion 411. The elastic member may be made of rubber or plastic, or may be formed so that the band-shaped metal plate bends and has an elastic force.

Referring to FIG. 5B, the protrusion 416 is elastically deformed in contact with the inner surface of the housing 310. One end 416a of the projection is fixed to the body portion 411 and the other end 416b is fixed to the body portion 411 in a first direction DR1 away from the one end 416a.

Between the first end 416a and the second end 416b, there is a protruding contact portion 416c. As shown, the contact portion 416c is resiliently deformed in contact with the upper housing 310. [ When the body portion 411 of the first lever is drawn out of the lever groove A, the projection 416 has a curved surface with a central portion protruding. When the first lever is mounted on the lever groove A, the contact portion 416c is elastically deformed in contact with the upper housing 310, and the contact between the contact portion and the upper housing 310 increases. The elastically deformed contact portion 416c applies a force to the upper housing 310 to bring the body portion 411 into close contact with the lower housing 320. [

That is, when the first lever is pulled out of the housing 300, the protrusion 416 is curved, and when the first lever is pulled into the housing 300, the first and second levers are elastically compressed and the face contacting the inner surface of the housing 300 is extended . The projection 416 pushes down the first lever by the restoring force. The lower surface of the first lever is brought into close contact with the lower housing 320 due to the restoring force and the upward and downward flow of the first lever is restricted.

FIGS. 7A to 7C are cross-sectional views of the socket module 300 taken along the line VII-VII of FIG. 3, illustrating embodiments for preventing the lateral flow of the first lever 410. FIG.

In the conventional case, a gap of about 0.05 mm exists on one side of the first lever 410. That is, there is a gap of about 0.1 mm on both sides of the first lever 410, which causes the flow of the first lever.

Referring to FIG. 7A, the housing 300 may be filled with the inside except for the lever groove A, the tray groove B, and the like. Alternatively, the protrusion wall 322 and the partition wall 323 may be formed in the housing 300. A lever groove in which the first lever is disposed is formed between the protruding wall 322 and the partition wall 323.

The head portion 412 includes a first extension portion 412a extending from one end of the body portion 411 toward the tray 500 and a second extension portion 412a extending from the one end of the first extension portion in a second direction DR2, Section 412b. That is, a protrusion facing the tray 500 is formed between the first extended portion 412a and the second extended portion 412b. The projection may be formed in contact with the tray 500 to limit the flow of the first lever.

On both sides of the lever groove, protrusions 325 and 326 facing each other are formed. The protrusions contact both sides of the lever body portion 411 to prevent the first lever from flowing. The protrusions 325 and 326 may be made of an elastic body. The elastic members apply an elastic force in opposite directions to each other to prevent the first lever from being pushed to one side of the lever groove. As a result, the first lever can slide smoothly.

7B is another embodiment for preventing the lateral flow of the first lever 410. As shown in FIG.

According to the drawings, protrusions 417 are formed on at least one side surface of the lever in contact with the protruding wall 322 or the boundary wall 323.

According to the drawings, there is a protruding contact portion having a curvature between one end and the other end of the protrusion 417. The contact portion can be resiliently deformed in contact with the protruding wall 322. When the body portion 411 of the first lever is drawn out of the lever groove A, the projection 417 has a curved surface with a central portion protruding. When the first lever is drawn into the lever groove A, the contact portion is elastically deformed in contact with the protrusion wall 322, and the contact area between the contact portion and the protrusion wall 322 increases. The elastically deformed contact portion applies a force to the protruding wall 322 to bring the body portion 411 into close contact with the boundary wall 323. Therefore, the body portion 411 is restricted from flowing to the left and right.

The protrusions may be formed on both side surfaces of the body portion 411. The protrusions on both side surfaces may have an elastic force, and the first lever 410 can be easily operated by preventing the body portion 411 from being shifted to one side.

7C is another embodiment for preventing the lateral flow of the first lever 410. As shown in FIG.

7C, the housing 300 includes a first protruding wall 322a, a second protruding wall 322b, and a partition wall 323, and the first lever 410 has a length A head 412 that is bent at one end of the body 411 and extends in a second direction DR2 and a second direction DR2 that is bent at the other end of the body 411, As shown in Fig.

An engagement region C is formed between the first projecting wall 322a and the second projecting wall 322b.

The body portion 411 may be curved to have a curvature in one direction. The body portion 411 includes a first contact region 411a and a second contact region 411c which are in contact with the boundary wall 323. The first contact area 411a is connected to the receiving part 413 and the second contact area 411c is connected to the head part 412. [ A curved region 411b is formed between the first contact region 411a and the second contact region 411c so as to protrude therefrom so as to be in contact with the boundary wall. The bend region 411b abuts the protruding wall 322 to limit the lateral flow of the first lever 410.

According to another embodiment of the present invention, the bending region 411b is formed to engage with the engaging region C. The edge 322a 'of the first protruding wall 322a may be formed with an oblique surface to allow the bending region 411b to slide. The edge 322b 'of the second protruding wall 322b may be formed with an oblique surface to allow the bending region 411b to slide.

The bent region 411b of the first lever is engaged with the engaging region C and the flow in the first direction DR1 and the second direction DR2 are restricted in a state in which the tray 500 is inserted into the tray groove B (II).

When the user applies a force in the first direction DR1 to the head portion 412, the bending region 411b slides in contact with the edge 322a 'of the first projecting wall 322a and is elastically deformed in the second direction DR2 (I).

That is, when the tray 500 is inserted into or drawn out from the tray groove B, the first lever 410 is deformed between the first state and the second state. In both states, the first lever is restricted from flowing in the second direction DR2. However, in the state II, the bending region 411b is fixedly engaged with the engaging region C, so that the first lever is prevented from being unintentionally moved in the first direction DR1 due to an external impact or the like.

8 is a conceptual diagram for explaining a state (a) and a drawn state (b) in which the tray 500 is pulled into the tray groove B. As shown in FIG. The tray groove B is formed between the boundary wall 323 and the protruding wall 322.

Referring to FIG. 8, the tray 500 includes a mold 501, a frame 502, an identification module seating portion 503, and the like.

The mold 501 may be formed to be engaged with the inlet of the tray groove B so as to prevent foreign matter from entering the tray groove B. That is, the mold 501 is formed wider than the frame 502 and engaged with the tray groove B.

The frame 502 is made smaller than the size of the tray groove B and can be inserted into the tray groove. In the frame 502, a hole 504 is formed at the center so that the identification module can contact the electrode terminal.

The frame 502 is formed with a seating portion 503 on which the identification module is seated, and the seating portion is formed so as to surround the hole 504. That is, the seat portion is disposed to overlap with the rim portion of the identification module, and the metal terminal of the identification module is exposed through the hole 504.

8 (a) shows a state in which the tray 500 is inserted into the tray groove.

Referring to FIG. 8A, the tray 500 is inserted and one end of the tray exerts a force on the second extension portion 423 of the second lever. The second extending portion 423 receives a downward force, and the second lever rotates counterclockwise about the rotational shaft coupled to the hinge hole 421. [ When the second lever rotates counterclockwise, the first extending portion 422 applies upward force to the receiving portion 413 of the first lever. The support portion is urged in the upward direction and the first lever moves upward. The protrusion 414 of the first lever contacts the protrusion wall 322 to prevent the first lever from flowing. The contact portion including the protruding portion 414 and the protruding wall 322 may be configured as described with reference to FIGS. The tray 500 can be taken out by applying a force in the direction of the arrow to the head 412 of the first lever.

8 (b) shows a state in which the tray is drawn out from the tray groove.

Referring to FIG. 8B, when a force is applied to the head 412, the first lever is moved downward and the second lever is rotated clockwise. In other words, the receiving portion 413 of the first lever applies a downward force to the first extending portion 422, and the second lever rotates clockwise about the rotating shaft coupled to the hinge hole 421. [ When the second lever rotates clockwise, the second extension portion 422 applies upward force to one side of the tray. The tray 500 is pulled out of the tray groove B by receiving force in the upward direction.

9 is a conceptual view showing another embodiment of the tray shown in FIG.

9 (a) includes a mold 501, a frame 502, an identification module seating portion 503, and the like.

In the frame 502, a hole 504 is formed so that the identification module can contact the electrode terminal. The frame 502 includes a seating portion 503 on which the identification module is seated, and a seating portion is formed to surround the hole 504. [ The contact area of the identification module is exposed through the hole 502.

The contact area of the identification module can be extended to overlap with the seating part. At this time, the seat portion may be coated with an insulating material to prevent the short-circuit failure from occurring due to the contact region and the seating portion being in contact with each other.

The tray 500 may be made of polycarbonate or a mixture of polycarbonate and glass fiber. By changing the material of the tray, the manufacturing process can be simplified and the material cost can be saved as compared with a method of adding or coating an insulating member.

When the contact area of the identification module is extended, the power contact part abuts against the contact area (A) of the seating part 503. In general, the tray is made of a metal material, and there is a risk of short-circuit failure due to the contact of the power source with the contact area (a).

In another embodiment of the present invention, the seat portion includes a first seat portion 503a and a second seat portion 503b.

The first seat portion extends from one side of the frame 502 toward the groove 504 and the second seat portion extends from the other side of the frame 502 toward the groove 504. [ The second seating portion 503b may be formed through the front surface and the other side of the frame. That is, as shown in the figure, they can be connected through two faces to form an L shape. As shown, the second seat portion is integrally formed as a whole extending from the front surface to the other side surface, but is not limited to this shape. In other words, the second seat portion may include an intermediate disconnected portion, and may be formed only on the other side surface or only on the front surface. And the second seat portion is formed only at a portion of the other side surface. In other words, it is formed so as to extend from one end formed to the outside of the contact region (A) to the front surface, so that the contact image of the identification module does not contact the seat.

The mobile terminal 100 described above is not limited to the configuration and the method of the embodiments described above, but the embodiments may be configured by selectively combining all or a part of each embodiment so that various modifications can be made .
