The terminal bodies 101 and 102 constitute an external appearance of the mobile terminal, and various components constituting the mobile terminal are disposed therein.

The circuit board 200 includes an insulating layer 210 which is embedded in the terminal body 101 and covers one surface of the terminal body 200 and a conductive pattern 210 which is recessed from the insulating layer 210 and is exposed in a predetermined pattern, (220).

In detail, the circuit board 200 includes a conductive layer and an insulating layer (solder resist layer) 210 stacked thereon. The insulating layer 210 is recessed from one side of the insulating layer 210 to expose a conductive layer stacked on the lower surface of the insulating layer 210. The conductive pattern 220 may be a solder resist open.

The first protrusions 411 of the connection member 400, which will be described later, are in contact with the conductive pattern portion 220 and are electrically connected to each other.

The cover member 300 is formed to cover at least a part of the circuit board 200. Further, the cover member 300 has a mounting portion 320 on which a module component 500 configured to perform an independent function is mounted.

In general, the circuit board 200 of the mobile terminal includes mounted electronic circuits, which are sensitive to electromagnetic interference (EMI) and electromagnetic interference (RFI). In particular, since electromagnetic disturbance noise originates from an interference source or an external interference source in the terminal, a shielding structure is required in order to block such interference and protect the electric devices 240. As one of such shielding structures, a cover member 300 such as one embodiment of the present invention can be considered. The cover member 300 is made of a stainless or titanium material that does not require plating, and is processed by a step-by-step molding operation using a press method.

The module component 500 includes a conductive pattern portion 510 mounted on a mounting portion 320 of the cover member 300 and exposed in a predetermined pattern. The module part 500 can input and output a signal from the outside and a signal from the inside through the conductive pattern part 220.

The module component 500 refers to a component that is assembled by assembling various components to perform one independent function, and examples thereof include a camera module, a speaker module, and a vibration motor module (a vibration mode operation module of the mobile terminal). In the present embodiment, a camera module is used for the module component 500.

The connecting member 400 is mounted on the cover member 300 to be sandwiched between the circuit board 200 and the cover member 300 and contacts the conductive pattern portion 220 of the circuit board 200 1 protrusion 411 and a second protrusion 421 contacting the conductive pattern 220 of the module component 500. [

The connection member 400 includes a first protrusion 411 formed on the first frame part 410 coupled to the conductive pattern part 220 of the circuit board 200, The second protrusion 421 is formed on the second frame part 420, which is engaged with the mounting part 320 of the second frame part 420.

The first projecting portion 411 and the second projecting portion 421 of the connecting member 400 have opposite projecting directions. This is because the camera module, which is the module component 500 of the present embodiment, is a camera module for rearward photographing and is coupled to the connecting member 400 in the direction opposite to the circuit board 200, and has first protrusions 411 and 2 protrusions 421 are formed.

The first protrusion 411 and the second protrusion 421 are formed at a predetermined angle a on one side of the connection member 400 and are formed so as to be elastically deformed As shown in Fig.

Since the first protrusion 411 and the second protrusion 421 are formed to have an elastic force greater than a certain level as described above, the impact of the electric element 240 due to buffering can be alleviated and good contact with the circuit board 200 You can maintain sex.

One end of the first protrusion 411 and one end of the second protrusion 421 may be formed to have a sharp point or a rounded surface by removing the rim of the first protrusion 411 and the second protrusion 421.

The cover member 300 and the connection member 400 can be integrated by spot welding or the like and the state in which the cover member 300 and the connection member 400 are integrated is referred to as a shield member It is also called collectively.

Fig. 5 is a perspective view showing a state in which the module parts are disassembled in a state where the circuit board, the connecting member, and the cover member are combined in Fig. 4, Fig. 6 is a perspective view showing a state in which the module parts are combined in Fig. 4 is a cross-sectional view showing a cross section taken along line AA in Fig.

The mounting portion 320 of the cover member 300 includes a mounting portion 321 on which the module component 500 is mounted and a fixing portion 322 surrounding the outer portion of the module component 500 And a guide portion 323 for guiding the second frame portion 420 of the connection member 400. [0031]

Further, the fixing portion 322 is formed of a plurality of fixing protrusions, and the fixing protrusions are spaced apart from each other, so that the flexible circuit board 510 connected to the module component 500 can pass through the space between the fixing protrusions .

A through hole 321a is formed in the seating portion 321 of the cover member 300 and a second projection portion 421 of the connection member 400 protrudes through the through hole 321a.

In this case, the second protrusion 421 may be longer than the first protrusion 411. This is because the second protruding portion 421 needs to be longer than the thickness t of the mounting portion 320 in order to connect with the module 500.

The module component 500 is mounted on the mounting portion 320 of the cover member 300 and the second protrusions 421 are electrically connected to the conductive pattern portion 220 of the module component 500 . The module component 500 may be adhered and fixed to the mounting portion 320 using an adhesive or the like.
