FIG. 2 illustrates an embodiment of the prior art related to the present invention.

The mobile terminal may include a housing 201 including the front case 101 (see FIG. 1B) and the rear case 102 (see FIG. 1B) to form the appearance of the mobile terminal. A plurality of components 203 may be mounted on the inner surface of the housing 201 and a PCB 202 may be mounted thereon. A shield can 204 is positioned to cover the plurality of parts 203. However, the switch 206, which is a component for determining whether a signal is generated as the user selectively presses the button unit 207, may be exposed to the outside of the shield can 204. The shield can 204 forms a closed curved surface around the outer periphery of the PCB 202 or around the periphery of the cover 202, and serves to prevent the shielding can from the outside.

The shield can 204 includes a top surface portion 2041 covering the component and a bottom end portion 2042 joined to the periphery of a component of the PCB portion 202 and a bottom portion 2042 connecting between the top surface portion 2041 and the bottom end portion 2042 And may have a side wall portion 2043.

One surface 2071 of the button portion is exposed to the outside of the mobile terminal and the other surface 2072 is directed to the inside of the mobile terminal so as to be in contact with the switch 206. [ The pressing portion 2073 which receives the physical force directly from the user and the pressing portion 2073 are indirectly deformed due to the pressure received by the pressing portion 2073, (2074). This fastening portion 2074 is fixed to the inside surface of the housing 201 of the mobile terminal 100 (see FIG. 1B). A protrusion 2011 is present on a housing inner surface 201 of the mobile terminal 100 (see FIG. 1B) and a groove 2075 of the coupling portion is inserted into the housing 201 of the mobile terminal 100 (see FIG. 1B) So as not to be detached from the inner side.

The button portion 207 may be located at least one side of the housing 201 of the mobile terminal 100 (see FIG. 1B), and may be located on the left side and the right side respectively, or may be located on one side.

The conventional method in which the button unit 207 is coupled to the housing 201 of the mobile terminal 100 (see FIG. 1B) has the following disadvantages.

First, a space is required to make the projection 2011 on the inner side surface of the housing 201 of the mobile terminal 100 (see Fig. 1B), and therefore, the PCB 202 also has to be located avoiding the space.

Secondly, the PCB 202 positioned inside the housing 201 of the mobile terminal 100 (see FIG. 1B) can have a flow with respect to the housing 201 of the mobile terminal 100 (see FIG. 1B) have. Also, the switch 202 may have a tolerance in the assembling process, and as a result, the contact reliability of the button portion 207 and the switch 206 may be deteriorated.

Thirdly, when the button unit 207 is located on the left and right sides of the mobile terminal 100 (see FIG. 1B), the button unit 207 may be damaged when the PCB unit 202 is seated in the assembling process.

FIG. 3 shows an embodiment related to the present invention.

The button portion 301 in the present invention can be coupled to the shield can 302, unlike the conventional art. A portion of the shield can 302 to which the button unit 301 is coupled is referred to as a fixing unit 405 (see FIG. 4). In the manufacturing process, the button unit 301 is mounted on the PCB 303 in a state of being fixed to the shield can 302 and can be brought into contact with the switch 304 mounted on the PCB 303 Can be located.

The shield can 302 is positioned so as to cover all parts except the switch 304, which are inevitably exposed when the cover 303 is viewed from the front.

In the case of this embodiment, the case where the button unit 301 is provided at the lower left end of the PC unit 303 will be described as an example. The PCB 303 is seated on the housing 1001 (see FIG. 1B) of the mobile terminal and the shield can 302 is fixed on the upper portion thereof. When the button portion 301 is fastened to the shield can 302 to be assembled, it is necessary to prevent the button portion 301 from being pulled out so as to have a certain degree of reliability.

FIG. 4 shows an embodiment related to the present invention.

As an example in which the shield can 402 and the button unit 401 are fastened together, an example as shown in Fig. 4 can be considered. The fixed portion 405 of the shield can 402 for fixing the button portion 401 to the shield can 402 has a first protrusion 403 having one end protruding in the direction toward the cover 303 (see Fig. 3) And a second protrusion 404 protruding in the opposite direction. The first protrusion 403 extends from the upper end portion 408 and the second protrusion 404 extends from the lower end portion 409 when the stepped portion of the shield can 402 is divided into the upper end portion 408 and the lower end portion 409 Can be. The first protrusion 403 may be engaged with the first groove 4071 existing in the fastening part 407 of the button part 401. [

The assembly of the shield can 402 and the button unit 401 is performed by inserting the button unit 401 obliquely into the lower inner side of the shield can 402 and then rotating again in the direction parallel to the shield can 402, The engagement between the groove 4071 and the first projection 403 and the engagement between the second groove 4072 and the second projection 404 can be tightly fitted. When the direction from the shield can 402 to the PCB unit 303 (see Fig. 3) is defined as the rear direction, the button unit 401 is prevented from being displaced in the plane direction parallel to the shield can 402 .

As shown in FIG. 4, the second grooves 4072 may exist more than one. In the present embodiment, the fastening portion 407 forms a closed curve together with the pressing portion 406 to form an opening at the center. When the closed curve is formed, the button portion 401 may be more stably coupled from the fixed portion 405 of the shield can 402, thereby minimizing the flow.

When the shield can 302 to which the button unit 301 is coupled is seated in the PC unit 303, the button unit 301 surrounds the periphery of the switch 304 of the PC unit 303 (See Fig. 3)

Since the button portion 401 is inserted obliquely into the shield can 402 and then rotated in parallel with the shield can 402, it is necessary to prevent the button portion 401 from being detached again in the oblique direction . The fixing portion 405 may have an end protruding in the direction of the PC portion in addition to the coupling of the first projection 403 and the first groove 4071 and the coupling of the second projection 404 and the second groove 4072, And a third projection 408 that supports one side of the portion.

5A and 5B are cross-sectional views taken along the line A-A 'and the line B-B', respectively, of a part of the shield can and the PCB according to the present invention.

5A shows a cross section of the shield can 501 and the PCB 503 in the A-A 'direction.

The shield can 501 can be combined with the PCB 503 through the stepped portion composed of the upper end portion 5011 and the lower end portion 5012 and the engaging member 505 in order to maintain the reliability of the component protection and radio performance.

5B is a cross-sectional view of the shield can 501 and the PCB 503 in the B-B 'direction. Unlike the cross section taken along the line A-A 'in FIG. 5A, the component 502 is inevitably exposed when it has the first protrusion 403 (see FIG. 4) and the second protrusion 404 (see FIG. 4). (5b-1) It is possible that the exposure would not be able to completely shield itself from simple physical protection as well as radio performance from the outside. In order to prevent this, an auxiliary shielding wall 504 that shields the components 502 mounted on the PC unit 503 from the outside may be further included (5b-2).

6A to 6C show another embodiment related to the present invention.

6A is a front perspective view of a button unit 601 according to another embodiment related to the present invention. There is a pressing part 602 which is exposed to the outside of the housing 1001 (see FIG. 1B) of the mobile terminal 100 (see FIG. 1B), and the pressing part 602, starting from both ends of the pressing part 602, And at least one insertion portion 604 protruding in the direction of the protrusion 603.

6B shows that the button portion 601 is coupled to the shield can 602 in accordance with another embodiment related to the present invention.

The fixing portion 608 of the shield can 602 may have an insertion fixing hole 605 so that the insertion portion 604 may be inserted and not flow. The insertion portion 604 may have a circular cross section, and at least two insertion portions 604 may be provided to prevent the insertion portion 604 from moving in the lateral direction of the mobile terminal 100 (see FIG. 1B). The insertion hole 605 may be provided as many as the number of the insertion portions 604.

6C shows a side view of the button portion 601 for another embodiment related to the present invention.

In the assembling process, the insertion portion 604 has a fitting portion 610 having the same diameter as the insertion fixing hole 605 (see FIG. 6B). 6B) that is larger than the diameter of the insertion fixing hole 605 (see FIG. 6B) is formed in the lower portion of the fitting portion 610 to prevent the insertion portion 604 from being separated again after being inserted into the insertion fixing hole 605 And has an inclined portion 608 which is narrowed in cross section toward the bottom of the end portion so as to facilitate the engagement.

Referring back to FIG. 6B,
