FIG. 2 is an exploded perspective view of a mobile terminal according to an embodiment of the present invention. FIG. 3 is an enlarged view of a rear case portion of the mobile terminal shown in FIG. Fig. 4B is a partial cross-sectional view taken along line II-II of the mobile terminal shown in Fig. 1B.

2 to 4, a mobile terminal 100 according to an embodiment of the present invention includes a case 101 and a case 102 forming a space for accommodating electronic components therein, A main circuit board 81 and a case 101 which are housed in the case 101 and 102 and in which the contact portion 82 is exposed through one side of the case 101 and 102 through a connecting hole 106 formed in the case 101 and 102, An interface module 1 which is seated in the seating grooves 107a and 107b formed on one surface of the main circuit board 102 and is connected to external equipment and is electrically connected to the main circuit board 81, A shielding cover 103 for shielding at least the interface module 1 and the contact portion 82 and a waterproof member 71 arranged to surround the connect hole 106 and watertight between the connect hole 106 and the outside, .

The interface module 1 may configure the interface unit 160 described above. The interface module 1 is a path through which the mobile terminal 100 can be connected to an external device. For example, the interface unit 160 may include a connection terminal for connection with another device (for example, an earphone or an external speaker), a port for short-range communication (for example, an infrared port (IrDA Port), a Bluetooth port A wireless LAN port, or the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented as a socket for receiving an external card such as a SIM (Subscriber Identification Module) or a UIM (User Identity Module) or a memory card for storing information.

Specifically, the interface module 1 may be a port to which one of an earphone, a speaker, a communication device, and a storage device is connected.

The interface module 1 is seated in the seating grooves 107a and 107b formed on one surface of the case 101 and 102 and is electrically connected to the main circuit board 81. [ The interface module 1 transfers input / output signals between the external device and the main circuit board 81.

The interface module 1 is seated in the seating grooves 107a and 107b formed on one surface of the case 101 and 102. [ Specifically, the interface module 1 is seated in the seating grooves 107a and 107b formed on the rear surface of the rear case 102. [

More specifically, the interface module 1 includes a connection terminal 12 to which an external device is connected, a base substrate 10 electrically connected to the connection terminal 12, And a connector 13 coupled to the contact portion 82 of the connector 81.

The base board 10 is electrically connected to at least one connection terminal 12 and the connector 13, and supports the connector 13.

The base substrate 10 transmits an electric signal input / output through the connection terminal 12. Specifically, the base board 10 transfers electrical signals between the connection terminals 12 and the main circuit board 81. [ Also, according to the embodiment, the base substrate 10 may convert the signal inputted from the main circuit board 81 into another signal and transmit it to the connection terminal 12. However, the present invention is not limited thereto.

The base substrate 10 is implemented as a printed circuit board (PCB) and is connected to a flexible printed circuit board 10 (not shown) so as to be connected to a main circuit board 81 (not shown) FPCB).

The base substrate 10 is seated in the rear case 102. Specifically, the base substrate 10 is accommodated in the seating grooves 107a and 107b formed on one surface (specifically, the rear surface) of the rear case 102. [

The connector 13 electrically connects the main circuit board 81 and the base board 10 and inputs and outputs electric signals generated by the base board 10. [ For example, the connector 13 may be formed of a conductive material, and may have a shape favorable to contact with an external power source. Specifically, the connector 13 has a shape that is elastically deformed.

The connector 13 is provided on one surface of the base substrate 10. Specifically, the connector 13 is positioned on one side of the base board 10 facing the main circuit board 81. [ More specifically, the connector 13 is connected to the contact portion 82 of the main circuit board 81.

The connection terminal 12 provides a place to which an external device is connected, and is electrically connected to the base substrate 10 to exchange signals.

Specifically, a part of the connection terminal 12 is exposed to the outside through the connection hole 102a on the side surface of the case 101 (102) (the side surface of the rear case 102). At this time, the connection terminal 12 may be submerged by water to be leaked. However, in order to prevent flooding of the main circuit board 81, the connector 13 and the connection terminal 12 are spaced apart from each other by a predetermined distance .

For example, the connection terminal 12 includes a socket portion 12a having one side exposed to the outside and connected to an external device, a connection portion 12b accommodated in the mounting recesses 107a and 107b and connected to the base substrate 10 ).

The socket portion 12a may have a structure such as a groove or a projection in order to facilitate coupling of external devices.

The cases 101 and 102 form a space for accommodating the electronic components therein. The case 101 (102) may be formed as a single component, but it is preferable to form a space in which the internal electronic parts are accommodated by the combination of the front case 101 and the rear case 102.

Mounting grooves 107a and 107b, an engaging groove 105 and a connecting hole 106 are formed on one surface of the case 101 and 102. One surface of the case 101 (102) may be a surface of the rear case 102 or a rear surface of the rear case 102.

The rear case 102 supports or receives the interface module 1. Specifically, the interface module 1 is supported on the rear surface of the rear case 102.

Specifically, a region where the interface module 1 is located is formed in the rear case 102. A protrusion or groove for determining the position of the interface module 1 may be provided in a region where the interface module 1 is located in the rear case 102. [ In the embodiment, as shown in Figs. 2 and 3, the rear case 102 is formed with seating grooves 107a and 107b in which the interface module 1 is received and / or seated.

The mounting grooves 107a and 107b determine the position of the interface module 1 and provide a space in which the interface module 1 is accommodated and the fluid flowing from the outside through the connection terminal 12 is stored. The seating grooves 107a and 107b are formed by recessing one side of the rear case 102 downward (in more detail, toward the front of the mobile terminal).

The seating grooves 107a and 107b accommodate at least a lower portion and a side portion of the interface module 1 so that the upper portion of the interface module 1 is exposed to the outside.

For example, the seating grooves 107a and 107b have a first seating groove 107a in which the connection terminal 12 is seated and a second seating 106b in which the base substrate 10 is seated, And a groove 107b.

The first seating groove 107a and the second seating groove 107b may have a shape corresponding to the shape of the connection terminal 12 and the base substrate 10. [ Therefore, the depths of the first seating groove 107a and the second seating groove 107b may be different from each other. Preferably, the first seating groove 107a is formed deeper than the second seating groove 107b.

A connection hole 102a through which a part of the connection terminal 12 is exposed is formed on the side surface of the case 101 (102). The side surfaces of the cases 101 and 102 where the connection hole 102a is formed are the side surfaces adjacent to the seating grooves 107a and 107b in the side surface of the rear case 102. [ This is because a part of the connection terminal 12 seated in the seating grooves 107a and 107b is exposed to the outside through the connection hole 102a. The connection hole 102a is a hole through which a part (more specifically, the socket portion 12a) of the connection terminal 12 passes.

The connection hole 102a communicates with the first seating groove 107a. Specifically, the connection hole 102a is formed in one of the side surfaces of the first seating groove 107a.

The diameter of the connection hole 102a passes through the socket portion 12a, but does not pass through the connection portion 12b. Therefore, when the seating grooves 107a and 107b have a size exactly the same as the connecting terminal 12, the connecting terminal 12 is moved in the forward direction from the rear and is seated in the seating grooves 107a and 107b, There is a problem that the socket portion 12a can not pass through the connection hole 102a.

Referring to FIG. 4, in order to solve the above-described problem, the width of the first seating groove 107a increases from one side of the first seating groove 107a toward the outside (from the front to the back of the mobile terminal) The inclined surface 21 is formed.

Specifically, the inclined surface 21 is disposed facing the connection hole 102a. More specifically, the inclined surface 21 is a side surface of the first seating groove 107a facing the side surface 22 of the first seating groove 107a in which the connection hole 102a is formed. In order to facilitate insertion of the connection terminal 12, the inclined surface 21 may have a stepped shape or be rounded.

 The width of the lower portion of the first seating groove 107a corresponds to the width of the lower portion of the connecting portion 12b and the width of the upper portion of the first seating groove 107a is larger than the width of the lower portion of the connecting portion 12b. The connecting terminal 12 is inserted into the first seating groove 107a from the rear side of the mobile terminal by the inclined surface 21 and is easily inserted into the connection hole 102a formed in the side surface 22, ) Can be inserted.

The second seating groove 107b provides a place where the base substrate 10 is seated. The second seating groove 107b has a shape corresponding to the base board 10. The second seating groove 107b accommodates the lower and side portions of the base substrate 10.

A coupling groove 105 is formed in the rear surface of the rear case 102 to receive and engage the shielding cover 103. The coupling groove 105 has a shape in which the back surface of the shielding cover 103 is exposed to the outside and a surface other than the back surface of the shielding cover 103 is received in the coupling groove 105.

Specifically, the mounting grooves 107a and 107b and the connecting hole 106 are disposed in the coupling groove 105. In addition, That is, the coupling groove 105 forms the periphery of the seating groove 107a, 107b and the connecting hole 106 in the rear case 102. [ Although the shape of the coupling groove 105 is not limited, a positioning portion 108 protruding inward or outward is disposed on the side surface of the coupling groove 105. The positioning portion 108 is combined with the shielding cover 103 to determine the engagement position of the shielding cover 103.

A hook groove 102b is formed on the rear surface of the rear case 102 to be engaged with the hook 103b of the shielding cover 103. [

A connector hole 106 through which the connector 13 is passed is formed in the rear case 102. The connector hole 106 penetrates the connector 13 for electrically connecting the interface module 1 to the control unit or the main circuit board 81.

Preferably, the connecting hole 106 is formed by opening one region of the seating groove 107a, 107b of the rear case 102. [ Specifically, for effective watertightness, the connect hole 106 is formed so that a part (bottom surface) of the second seating groove 107b of the rear case 102 is opened. At this time, the depth of the first seating groove 107a is formed to be deeper than the depth of the second seating groove 107b, so that the water introduced through the connection terminal 12 is primarily supplied to the first seating groove 107a .

Particularly, the main circuit board 81 is positioned in front of the rear case 102 and the main circuit board 81 has a contact portion 82 in contact with the connector 13. At this time, the contact portion 82 of the main circuit board 81 is exposed through the connect hole 106 and comes into contact with the connector 13. The electrical connection between the interface module 1 and the main circuit board 81 is facilitated by the connect hole 106. [ The main circuit board 81 is housed in the case 101 (102).

The waterproofing member 71 is tightly sealed between the connect hole 106 and the exterior to prevent water introduced into the interface module 1 from entering the main circuit board 81 or the connector 13 from the outside. Further, the waterproofing member 71 seals between the connector 13 and the outside. Particularly, since the connector 13 is electrically connected to the control unit of the mobile terminal and / or the main circuit board 81, if a fluid flows into the connector 13, a catastrophic failure occurs.

The base substrate 10 covers the peripheral area (specifically, the second seating groove 107b) of the connect hole 106 and the connect hole 106 of the case 101 and the case 102. At this time, the waterproofing member 71 is in contact with one surface of the case 101 or 102 forming the periphery of the base substrate 10 and the hole of the connector 13.

The waterproofing member 71 is water tight between the rear case 102 and the base substrate 10. Specifically, the waterproofing member 71 is disposed in close contact with or in contact with the facing surfaces of the rear case 102 and the base substrate 10. The waterproof member 71 of the embodiment is in contact with the rear surface of the rear case 102 and the front surface of the base substrate 10. [

According to the embodiment, a groove (not shown) may be formed on one surface of the rear case 102 and / or the base substrate 10 to insert the waterproof member 71 therein. These grooves determine the position of the waterproofing member 71.

The waterproof member 71 is arranged to surround the connecting hole 106 of the rear case 102 when viewed from the front of the mobile terminal so as to prevent the fluid from leaking to the connector 13 and the main circuit board 81 . At this time, the waterproofing member 71 is brought into contact with the seating grooves 107a and 107b in the periphery of the connect hole 106. [

The waterproofing member 71 may be a material that is elastically deformed. For example, the waterproof member 71 includes a resin material such as rubber or silicone having elasticity. The waterproofing member 71 may also include an adhesive tape or a waterproof tape.

The waterproofing member 71 floods only the interface module 1, not the important component, even if the fluid flows from the outside through the interface module 1, and the waterproof member 71 is immersed in the portion other than the interface module 1 (main circuit board 81) Thereby preventing fluid from entering.

The shielding cover 103 is coupled to one surface of the case 101 or 102 to shield at least the interface module 1 and the contact portion 82. That is, it covers a part of the rear surface of the rear case 102 of the shielding cover 103. The rear surface of the shielding cover 103 is disposed on the same line as the rear surface of the rear case 102. [

The shielding cover 103 has a shape to be coupled to the coupling groove 105 formed in the rear case 102. More specifically, the shielding cover 103 further includes a positioning portion 103a that cooperates with one surface of the case 101 (102) to determine the position of the shielding cover 103. [ The positioning portion 103a may be a groove or a projection which is formed with a projection or groove formed on a side surface of the coupling groove 105. [

The shielding cover 103 may further include a position fixing protrusion 103c for pressing the connection terminal 12 to fix the position of the connection terminal 12. [

The position fixing protrusion 103c presses the connection terminal 12 in the direction of the connection hole 102a. Preferably, the position fixing protrusion 103c can be inserted between the side surface of the connecting portion 12b and the inclined surface 21. When the shielding cover 103 is coupled by the position fixing protrusion 103c, the position of the connection terminal 12 is fixed.

The shielding cover 103 may further include an antenna for receiving an electrical signal and transmitting it to the main circuit board 81. The antenna receives a wireless communication signal.

The antenna may be formed in the shielding cover 103. For example, the antenna forming part of the broadcast receiving module 111 (see FIG. 1A) may be formed in a film type and attached to the inner surface of the shielding cover 103. As another example, the antenna may be configured such that the shielding cover 103 including a conductive material functions as an antenna.
