Description

electronic devices

[0001] The embodiment relates to an electronic device.

[0002] An electronic device that supplies power may include a case and a circuit board positioned within the case. Electronic components may be mounted on the circuit board. The electronic device may also include a blower for blowing outside air into the case. The case may include a panel having air vents corresponding to the blower.

[0003] These electronic devices require a configuration that allows the user to visually perceive the product's operation. Typically, a configuration exists that notifies the user of the product's operation through light. To achieve this, a substrate is placed near the panel, a light source is placed on the substrate, and the light emitted from the light source is transmitted to the outside of the panel, enabling the user to perceive it.

[0004] At this time, the substrate is fixed to the panel, and the panel and substrate need to be insulated. Furthermore, the light emitted from the light source needs to be transmitted to the outside of the panel with good visibility.

[0005] Accordingly, the purpose of the present invention is to solve the above-described problems, and to provide an electronic device that insulates a panel and a substrate and allows light emitted from a light source to be transmitted to the outside of the panel with good visibility.

[0006] The problems to be solved by the embodiment are not limited to the problems mentioned above, and other problems not mentioned herein will be clearly understood by those skilled in the art from the description below.

[0007] An embodiment for achieving the above object may provide an electronic device including a case including a panel having a light-transmitting hole formed therein, a substrate disposed in the case so as to face the panel and having a light source disposed therein, and an intermediate member including a light-transmitting portion aligned with the light source, wherein the intermediate member is disposed between the panel and the substrate to space the panel and the substrate apart from each other, and the substrate and the intermediate member are fastened to the panel through a fastening member including an insulating region.

[0008] The substrate may include a first connector to which an external device is connected, the intermediate member may include a body aligned with the light source, and an extension extending from the body and aligned with the first connector, and the extension may include a hole exposing the first connector.

[0009] The body may include a first receiving portion forming an internal space, the extension portion may include a second receiving portion forming an internal space, the light source may be located inside the first receiving portion, and the first connector may be located inside the second receiving portion.

[0010] The first receiving portion may include a first surface in contact with the panel and a second surface in contact with the substrate.

[0011] The above light transmitting portion can be placed in the first receiving portion.

[0012] The first receiving portion includes a first outer wall spaced apart from the outer surface of the body and a first side wall connecting the outer surface of the body and the first outer wall, and the first outer wall can be in contact with the panel.

[0013] The first receiving portion may include a rib protruding from the inner wall of the first outer wall, and the light transmitting portion may be arranged on the inner side of the rib.

[0014] The above rib can be in contact with the substrate.

[0015] A part of the light-transmitting portion may protrude beyond the outer surface of the first outer wall, and another part of the light-transmitting portion may protrude beyond the inner surface of the first outer wall.

[0016] The above insulating member includes a nut portion fixed to the panel and a bolt portion that penetrates the substrate and the intermediate member and is coupled to the nut portion, the nut portion is made of an insulating material, and an end of the nut portion can be in contact with the body.

[0017] The body includes a groove, a seating surface formed by the bottom surface of the groove, and a through hole arranged on the seating surface, the nut portion contacts the seating surface, and the bolt portion can be fastened to the nut portion by passing through the through hole.

[0018] The second receiving portion can be in contact with the panel.

[0019] The second receiving portion includes a second outer wall spaced apart from the body and a second side wall connecting the body and the second outer wall, and the second outer wall can be in contact with the panel.

[0020] The first outer wall and the second outer wall may be positioned on the same plane.

[0021] The distance between the above light transmitting portion and the light source may be within the range of 1.2 mm to 3.2 mm.

[0022] According to the embodiment, there is an advantage in that a sufficient distance for insulation can be secured between the substrate and the panel through the intermediate member and the insulating member.

[0023] According to an embodiment, there is an advantage in that the light from the light source is spread out rather than concentrated through the light-transmitting portion, thereby enabling good visibility to be transmitted to the outside of the panel.

[0024] According to an embodiment, the distance between the light transmitting portion and the light source is set to a range of 1.2 mm to 3.2 mm, thereby securing the assemblyability of the intermediate member while increasing the visibility of the light from the light source.

[0025] According to an embodiment, there is an advantage of accommodating a first connector that is connected to an external device through an extension of the intermediate member without the addition of a separate component.

[0049] FIG. 1 is a drawing illustrating an electronic device (10) according to an embodiment, FIG. 2 is an exploded view of the electronic device (10) illustrated in FIG. 1, and FIG. 3 is an enlarged view of the electronic device (10) illustrated in FIG. 2.

[0050] Hereinafter, in the drawings, the x-axis represents the front-back direction (x) of the electronic device (10), the y-axis represents the width direction (y) of the electronic device (10), and the z-axis represents the up-down direction (z) of the electronic device (10). Hereinafter, front and rear are based on the front-back direction (x) of the electronic device (10).

[0051] Referring to FIGS. 1 to 3, an electronic device (10) according to an embodiment may include a case (100), a substrate (200), an intermediate member (300), and a fastening member (400).

[0052] The case (100) can form a space for receiving a substrate (200) therein. The case (100) can include a panel (110). The panel (110) can be located on one side of the front or rear of the case. The panel (110) can include an air vent (111).

[0053] The substrate (200) is spaced apart from the panel (110) in the front-back direction (x). Electronic components may be mounted on the substrate (200). In addition, a plurality of light sources (210) may be mounted on the substrate (200). For example, the light sources (210) may be arranged in a row along the up-down direction (z). Each light source (210) may be turned on and off or its color may change depending on the operating state of the electronic device (10). A first connector (C1) may be arranged on the substrate (200). The first connector (C1) is a place where an external device is connected. For example, a test device for testing the electronic device (10) may be electrically connected to the first connector (C1).

[0054] The intermediate member (300) is disposed between the panel (110) and the substrate (200), and prevents the panel (110) made of a metal material from coming into contact with the substrate (200) or the electronic elements mounted on the substrate (200), thereby electrically insulating the panel (110) and the substrate (200) or the electronic elements mounted on the panel (110) and the substrate (200). In addition, the intermediate member (300) may include a light-transmitting portion (310). The light-transmitting portion (310) serves to spread light emitted from a light source to increase user visibility. A plurality of light-transmitting portions (310) may be disposed in a row along the vertical direction (z). The position of the light-transmitting portion (310) may correspond to the position of the light source.

[0055] The fastening member (400) serves to fasten the substrate (200) and the intermediate member (300) to the panel (110). The fastening member can penetrate the substrate (200) and the intermediate member (300) and be fixed to the panel (110). The fastening member (400) includes an insulating region and serves to insulate the substrate (200) and the panel (110).

[0056] Figure 4 is an enlarged view of the panel (110).

[0057] Referring to FIGS. 3 and 4, the panel (110) may include a plurality of light-transmitting holes (111a). The plurality of light-transmitting holes (111a) may be arranged in a row. In addition, the panel (110) may include a hole (112) that exposes the first connector (C1).

[0058] The electronic device (10) may include a cover (500). The cover (500) may be coupled to the panel (110) to cover the hole (112). The cover (500) may be coupled to a fastening structure disposed on the substrate (200) by penetrating the panel through a separate bolt (B).

The first connector (C1) may be located on one side of the substrate (200) in the forward-backward direction (x). The substrate (200) includes a second connector (C2). The second connector (C2) is for connecting another substrate (200) of an electronic device (10). The second connector (C2) may be located on the other side of the substrate (200) in the forward-backward direction (x). The positions of the first connector (C1) and the second connector (C2) may be different in the vertical direction (z).

[0061] Meanwhile, the substrate (200) may include a fastening hole (220). The fastening hole (220) is formed by penetrating the substrate (200) in the front-back direction (x). A plurality of fastening holes (220) may be arranged. For example, two fastening holes (220) may be formed in the substrate (200), and one of the two fastening holes (220) may be positioned above the light source (210) in the vertical direction (z), and the other of the two fastening holes (220) may be positioned below the light source (210) in the vertical direction (z).

[0062] Fig. 6 is a perspective view showing the front side of the intermediate member (300), Fig. 7 is a perspective view showing the rear side of the intermediate member (300), and Fig. 8 is a side cross-sectional view of the intermediate member (300).

[0063] Referring to FIGS. 6 to 8, the intermediate member (300) may include a light-transmitting portion (310), a body (320), and an extension portion (330).

[0064] A plurality of light transmitting portions (310) may be arranged. The light transmitting portions (310) serve to gently spread the light emitted from the light source (210) and guide it to the outside of the panel (110).

[0065] The body (320) can be aligned with the light source (210) of the substrate (200).

[0066] The body (320) may include a first receiving portion (321) forming an internal space. The first receiving portion (321) forms a space that includes a light source (210) of the substrate (200) on the inside. The first receiving portion (321) may include a first outer wall (321a), a first side wall (321b), and a rib (321c). The first outer wall (321a) is positioned spaced apart from the outer surface of the body (320). The first side wall (321b) connects the outer surface of the body (320) and the first outer wall (321a). That is, the first outer wall (321a) protrudes forward to form a space on the inside. The rib (321c) protrudes from the inner wall of the first outer wall (321a).

[0067] A plurality of light-transmitting portions (310) may be arranged in the first receiving portion (321). A portion of the light-transmitting portions (310) may protrude beyond the outer surface of the first outer wall (321a). Another portion of the light-transmitting portions (310) may protrude beyond the inner surface of the first outer wall (321a). All of the plurality of light-transmitting portions (310) may be positioned within the rib (321c).

[0068] The first receiving portion (321) may include a first surface (S1) that contacts the panel (110) and a second surface (S2) that contacts the substrate (200). The first surface (S1) corresponds to the outer surface of the first outer wall (321a) and may contact the outer surface of the panel (110). The second surface (S2) is an end surface of a rib (321c) and may contact the substrate (200). Since the rib (321c) contacts the substrate (200), the rib (321c) confines the light irradiated from the light source (210) located inside the rib (321c), thereby preventing the light from leaking to the outside of the first receiving portion (321).

[0069] The body (320) may include a groove (G) formed concavely on the outer surface. The groove (G) may be arranged near the edge of the body (320). A through hole (321d) is arranged in the groove (G). The through hole (321d) may be formed by penetrating from one side of the body (320) to the other side in the front-back direction (x). A plurality of grooves (G) may be arranged. For example, two grooves (G) may be arranged. One of the two grooves (G) may be located above the light source (210), and the other of the two grooves (G) may be located below the light source (210). A through hole (321d) may be arranged in each of the two grooves (G).

[0070] The extension (330) may extend from the body (320). The extension (330) may extend from one side of the body (320) in the vertical direction (z). The extension (330) is positioned to be aligned with the first connector (C1) of the substrate (200). The extension (330) may include a hole (330a) that exposes the first connector (C1). In addition, the extension (330) includes a second receiving portion. The second receiving portion (331) forms an internal space that receives the first connector (C1). The extension (330) may include a second outer wall (331a) and a second side wall (331b). The second outer wall (331a) is spaced apart from the body (320).

[0071] Figure 9 is a cross-sectional side view of the panel (110), the intermediate member (300), and the substrate (200).

[0072] Referring to FIGS. 6 to 9, when the intermediate member (300) and the substrate (200) are combined with the panel (110), the light-transmitting portion (310) is inserted into the light-transmitting hole (111a) of the panel (110). A portion of the light-transmitting portion (310) may be positioned to protrude beyond the panel (110).

[0073] The first surface (S1) of the first receiving portion (321) contacts the inner surface of the panel (110). The second surface (S2) formed on the rib (321c) contacts the substrate (200). The panel (110) and the substrate (200) are spaced apart from each other by a predetermined distance (D) by an intermediate member (300). Since the intermediate member (300) is made of an insulating material, the panel (110) and the substrate (200) are insulated.

[0074] The light transmitting portion (310) is aligned with the light source (210). Light emitted from the light source (210) spreads smoothly as it passes through the light transmitting portion (310) and is transmitted to the outside of the panel (110).

[0075] Figure 10 is a drawing showing the bonding relationship between an intermediate member (300) and a substrate (200).

[0076] Referring to Fig. 10, the fastening member (400) may include a nut portion (410) and a bolt portion (420). The nut portion (410) is fixed to the panel (110). The bolt portion (420) may penetrate the substrate (200) and the through hole (321d) of the intermediate member (300) to be fastened to the nut portion (410). When the bolt portion (420) is fastened to the nut portion (410), the first connector (C1) is received in the second receiving portion (331), and the first connector (C1) is exposed by the hole (330a).

[0077] Figure 11 is a drawing showing the distance (d) between the light transmitting portion (310) and the light source (210).

[0078] Referring to Fig. 11, in the forward-backward direction (x), the distance (d) between the end of the light-transmitting portion (310) and the light source (210) may be within the range of 1.2 mm to 3.2 mm. Within this range, the assemblability of the intermediate member (300) and the substrate (200) can be secured while the visibility of the light irradiated from the light source (210) can be improved. Specifically, when the distance between the end of the light-transmitting portion (310) and the light source (210) is less than 1.2 mm, the visibility of the light irradiated from the light source (210) can be improved; however, there is a risk that the light-transmitting portion (310) may touch the light source (210) due to tolerance during the process of assembling the intermediate member (300) and the substrate (200). And if the distance between the end of the light transmitting portion (310) and the light source (210) is greater than 3.2 mm, the distance between the light transmitting portion (310) and the light source (210) is sufficiently secured, but there is a problem that the amount of light irradiated from the light source (210) that is incident on the light transmitting portion (310) becomes small.

[0079] Figure 12 is a cross-sectional side view showing in detail the fastening structure of the intermediate member (300) and the substrate (200).

[0080] Referring to Fig. 12, the nut portion (410) is fixed to the panel (110). The bolt portion (420) penetrates the substrate (200) and the intermediate member (300) and is rotationally fastened to the nut portion (410). As the bolt portion (420) is rotationally fastened to the nut portion (410), the end of the nut portion (410) comes into contact with the groove (G) of the intermediate member (300). Since the nut portion (410) comes into contact with the groove (G) of the intermediate member (300), the bonding strength between the substrate (200) and the intermediate member (300) can be increased. The nut portion (410) can be formed of an insulating material. Since the nut portion (410) is formed of an insulating material, the panel (110) and the substrate (200) can be insulated.
