[0053] However, it is not limited to this, and the printed circuit board (51) may be provided at various locations in the case (20, 30, 40).

[0054] As described above, the configuration according to the concept of the present disclosure is not limited to being applied to a display device (1) and can be applied to various types of electronic devices (1).

[0055] A display device (1) according to one embodiment of the present disclosure may be referred to as an electronic device, and a case (20, 30, 40) of the display device (1) may be referred to as a main body of the electronic device.

[0056] The description of the configuration of the printed circuit board of the electronic device according to the concept of the present disclosure may be consistent with or similar to the description of the configuration of the printed circuit board assembly (50) of the display device (1).

[0057] Therefore, for convenience of explanation, the following description of examples according to the concept of the present disclosure is based on a display device (1), which is a type of electronic device, and descriptions of other types of electronic devices or general descriptions of electronic devices may be omitted.

[0058] The printed circuit board assembly (50) may include a printed circuit board (51) mounted on the bottom chassis (40) of the case (20, 30, 40) and electronic components mounted on the printed circuit board (51).

[0059] A printed circuit board (51) can be formed by printing a circuit line pattern with a conductive material, such as copper, on an electrically insulating substrate.

[0060] The circuit line pattern on the printed circuit board (51) and the electronic components mounted on the printed circuit board (51) can be provided in various ways depending on the functions that the printed circuit assembly (50) intends to provide.

[0061] The printed circuit board assembly (50) can be provided in various types of printed circuit board assemblies (50) according to the function or configuration to be provided for driving the display device (1).

[0062] For example, the printed circuit board assembly (50) may include a main board, a power supply board, a source board, etc.

[0063] The main board may include a processor and a power management device for driving the display device (1). The power supply board may supply power for driving the display device (1). The source board may control the display panel (10) of the display device (1).

[0065] As illustrated in FIG. 2, a plurality of printed circuit board assemblies (50) may be provided, and each of the plurality of printed circuit board assemblies (50) may be composed of the aforementioned main board, power supply board, source board, etc. The plurality of printed circuit board assemblies (50) may be electrically connected to each other to perform a function for driving the display device (1). However, alternatively, the printed circuit board assemblies (50) may be configured to be integrated with each other to perform a function.

[0066] In the following, the printed circuit board assembly (50) is described as a power supply board.

[0067] However, the concept of the present disclosure is not limited to cases where the printed circuit board assembly (50) is configured as a power supply board, and the concept of the present disclosure may also be applied to other types of printed circuit board assemblies (50) other than the power supply board.

[0068] The power supply board (50) may be configured to receive power from an external power source and supply power to the display device (1). The power supply board (50) may include various components mounted on the printed circuit board (51) to supply power for driving the printed circuit board (51) and the display device (1).

[0069] The power supply board (50) may include a switch mode power supply board, i.e., an SMPS board (Switched Mode Power Supply Board), which includes a switch element that performs an on / off switching operation.

[0070] The SMPS board is a modular power supply board that converts electricity supplied from an external source so that it can be used in various electronic devices such as computers, TVs, and wireless communication devices. It performs the role of converting commercial power into high-efficiency / high-quality power required by various electronic devices by utilizing the switching function of semiconductor devices and the power conversion function of a transformer. For example, the power supply board (50) may include a power converter.

[0071] FIG. 3 illustrates a part of a power supply board according to one embodiment of the present disclosure. FIG. 4 illustrates a disassembled view of a part of the power supply board and a power cord according to one embodiment of the present disclosure. FIG. 5 illustrates a cross-section along the line A-A' indicated in FIG. 3. FIG. 6 illustrates a cross-section along the line B-B' indicated in FIG. 3.

[0072] Referring to FIGS. 3 and 4, a power supply board (50) according to one embodiment of the present disclosure may include a power inlet (100) configured to be connectable to a power cord (120). As the power cord (120) is connected to the power inlet (100), the power supply board (50) may receive power from the power cord (120). The external power source may be an AC power source. The power inlet (100) may be mounted on a printed circuit board (51) of the power supply board (50).

[0073] A power inlet (100) according to one embodiment of the present disclosure may include an inlet body (101). The inlet body (101) may be mounted on a printed circuit board (51) of a power supply board (50).

[0074] The inlet body (101) may include a cord coupling portion (102a, 102b, 102c) for coupling with a power cord (120). For example, the cord coupling portion (102a, 102b, 102c) may include a first cord coupling portion (102a), a second cord coupling portion (102b), and a third cord coupling portion (102c). As an example, the cord coupling portion (102a, 102b, 102c) may include a space capable of accommodating at least a portion of the power cord (120).

[0075] For example, the first code coupling part (102a), the second code coupling part (102b), and the third code coupling part (102c) may be arranged in a line. Referring to FIGS. 3 and 4, the second code coupling part (102b) may be placed on one side of the first code coupling part (102a), and the third code coupling part (102c) may be placed on the other side opposite to the one side of the first code coupling part (102a). The arrangement order of the first code coupling part (102a), the second code coupling part (102b), and the third code coupling part (102c) is not limited to what is described above. The first code coupling part (102a), the second code coupling part (102b), and the third code coupling part (102c) may be arranged in the direction in which the printed circuit board (51) of the power supply board (50) extends. According to this configuration, the thickness of the power supply board (50) of the electronic device (1) according to one embodiment of the present disclosure may be reduced, and as the thickness of the power supply board (50) is reduced, the thickness of the electronic device (1) may be reduced.

[0076] A power inlet (100) according to one embodiment of the present disclosure may include a first terminal (105), a second terminal (106), and a third terminal (107). For example, the first terminal (105) may include a ground terminal, the second terminal (106) may include a live terminal, and the third terminal (107) may include a neutral terminal. However, the first terminal (105), the second terminal (106), and the third terminal (107) are not limited thereto, and for example, the second terminal (106) may include a neutral terminal and the third terminal (107) may include a live terminal.

[0077] In the following, for example, the first terminal (105) may be received in the first code coupling part (102a), the second terminal (106) may be received in the second code coupling part (102b), and the third terminal (107) may be received in the third code coupling part (102c).

[0078] The inlet body (101) may include partitions (103a, 103b) for partitioning the first code coupling part (102a), the second code coupling part (102b), and the third code coupling part (102c) from each other. For example, the inlet body (101) may include a first partition (103a) partitioning the first code coupling part (102a) and the second code coupling part (102b), and a second partition (103b) partitioning the first code coupling part (102a) and the third code coupling part (102c).

[0079] The partitions (103a, 103b) may extend from one end of the inlet body (101) to the other end in the direction in which the power cord (120) is coupled to the power inlet (100) (e.g., Z direction). According to this configuration, the electronic device (1) according to one embodiment of the present disclosure can improve safety by satisfying the insulation specifications between the terminals (105, 106, 107) by the partitions (103a, 103b). In addition, the electronic device (1) according to one embodiment of the present disclosure can reduce interference between the first terminal (105), the second terminal (106), and the third terminal (107).

[0080] Referring to FIGS. 3 and 4, a second terminal (106) may be located to the left of the first terminal (105) and a third terminal (107) may be located to the right. However, the positions of the second terminal (106) and the third terminal (107) are not limited thereto, and the second terminal (106) may be located to the right of the first terminal (105) and the third terminal (107) may be located to the left of the first terminal (105).

[0081] An electronic device (1) according to one embodiment of the present disclosure may further include a power cord (120). The power cord (120) may be provided to supply external power to the electronic device (1). The power cord (120) may be detachably coupled to a power inlet (100) of a power supply board (50). The power cord (120) may be electrically connected to the power inlet (100).

[0082] A power cord (120) according to one embodiment of the present disclosure may include a cord body (121) and connector portions (122a, 122b, 122c) protruding from the cord body (121). The connector portions (122a, 122b, 122c) may be detachably coupled to cord coupling portions (102a, 102b, 102c) of a power inlet (100). The cord body (121) of the power cord (120) may be provided with a wire (123) for receiving power from an external source.

[0083] For example, the connector portions (122a, 122b, 122c) may include a first connector portion (122a), a second connector portion (122b), and a third connector portion (122c). The first connector portion (122a) can be detachably coupled to the first code coupling portion (102a), the second connector portion (122b) can be detachably coupled to the second code coupling portion (102b), and the third connector portion (122c) can be detachably coupled to the third code coupling portion (102c).

[0084] The first connector part (122a), the second connector part (122b), and the third connector part (122c) may be arranged to be separated and spaced apart from each other. For example, when the power cord (120) is connected to the power inlet (100), a first partition (103a) may be located between the first connector part (122a) and the second connector part (122b), and a second partition (103b) may be located between the first connector part (122a) and the third connector part (122c).

[0085] A power inlet (100) according to one embodiment of the present disclosure may be provided such that at least one of a first code coupling part (102a), a second code coupling part (102b), and a third code coupling part (102c) has a shape and / or size different from the other.

[0086] For example, the first code coupling part (102a) may be provided to have a shape different from that of the second code coupling part (102b) and the third code coupling part (102c). The cross-section perpendicular to the direction in which the power cord (120) of the first code coupling part (102a) is inserted may have a shape different from the cross-section perpendicular to the direction in which the power cord (120) of the second code coupling part (102b) is inserted and the cross-section perpendicular to the direction in which the power cord (120) of the third code coupling part (102c) is inserted. As an example, the lower corner portion of the first code coupling part (102a) may be formed to be inclined, and the upper corner portions of the second code coupling part (102b) and the third code coupling part (102c) may be formed to be inclined. The cross-section perpendicular to the direction in which the power cord (120) of the second code coupling part (102b) is inserted can be provided in the same way as the cross-section perpendicular to the direction in which the power cord (120) of the third code coupling part (102c) is inserted.

[0087] A cross-section perpendicular to the direction in which the power cord (120) of the first connector part (122a) is coupled to the power inlet (100) may correspond to a cross-section perpendicular to the direction in which the power cord (120) of the first cord coupling part (102a) is coupled to the power inlet (100). A cross-section perpendicular to the direction in which the power cord (120) of the second connector part (122b) is coupled to the power inlet (100) may correspond to a cross-section perpendicular to the direction in which the power cord (120) of the second cord coupling part (102b) is coupled to the power inlet (100). A cross-section perpendicular to the direction in which the power cord (120) of the third connector part (122c) is coupled to the power inlet (100) may correspond to a cross-section perpendicular to the direction in which the power cord (120) of the third cord coupling part (102c) is coupled to the power inlet (100).
