[0006] An electronic device may include a plurality of circuit boards. When the circuit boards are connected to each other by a connector for board-to-board connection, it may be necessary to remove the circuit boards in a manner corresponding to the combination of these circuit boards. For this reason, when a user or the like wants to replace a specific circuit board among these circuit boards, the specific circuit board may not be removed quickly. Based on the above preliminary explanation, an embodiment will be described below.

[0007] (One Embodiment) FIG. 1 is a perspective view of an electronic device 10 according to an embodiment. FIG. 2 is an exploded view of the electronic device 10 of FIG. 1.

[0008] The electronic device 10 is, for example, a control device for controlling industrial machinery. The industrial machinery is, for example, a robot, but is not limited to that. The electronic device 10 comprises a housing 12 and a plurality of electronic units 14 (control unit 54, power supply unit 56).

[0009] The housing 12 is a structure having a housing space 16 and a housing opening (housing opening) 18. The housing space 16 is a space formed inside the housing 12. The housing 12 can house a plurality of electronic units 14 in the housing space 16. The housing opening 18 is an opening formed in the housing 12. The housing opening 18 is formed, for example, at the top of the housing 12, but is not limited thereto. The housing opening 18 communicates with the housing space 16. The electronic units 14 can be housed in or removed from the housing space 16 through the housing opening 18. In this embodiment, the direction in which the electronic units 14 are removed from inside the housing space 16 to outside the housing space 16 through the housing opening 18 corresponds to the first direction D1 shown in Figures 1, 2, etc. (see also Figure 8).

[0010] The housing 12 comprises a housing bottom portion 20 and a housing lid portion 22. The housing bottom portion 20 forms the bottom surface of the housing 12. The housing lid portion 22 is a lid that covers the housing opening 18. The housing lid portion 22 is, for example, a top plate that forms the top surface of the housing 12.

[0011] The housing 12 further comprises a pair of housing side sections 26 (261, 262), a housing front section 28, and a housing rear section 30. In the following description, one of the pair of housing side sections 26 will also be referred to as the first housing side section 261, and the other of the pair of housing side sections 26 will also be referred to as the second housing side section 262.

[0012] Each of the pair of housing sides 26 is formed in a wall shape to constitute the side of the housing 12. The direction from the first housing side 261 to the second housing side 262 intersects with the removal direction described above. In this embodiment, the direction from the first housing side 261 to the second housing side 262 coincides with the second direction D2 shown in Figures 1 and 2. The second direction D2 is perpendicular to the first direction D1.

[0013] At least one of the pair of housing side portions 26 is detachable from the housing bottom portion 20. In that case, as shown in Figure 2, both of the pair of housing side portions 26 may be detachable from the housing bottom portion 20.

[0014] The housing side portion 26, which is detachable from the housing bottom portion 20, may be integrated with the housing lid portion 22 described above. In that case, as shown in Figure 2, both of the pair of housing side portions 26 may be integrated with the housing lid portion 22.

[0015] The front portion 28 of the housing is formed in a wall shape to constitute the front of the housing 12. The front portion 28 of the housing may be provided with an external connection interface 32. The external connection interface 32 includes various interfaces for connecting external devices to a plurality of electronic units 14 housed in the housing space 16. For example, an external power supply connection section 321 is included in the external connection interface 32, but is not limited to this. An external power supply, which is a power supply provided outside the electronic device 10, is connected to the external power supply connection section 321. The external power supply is connected to a power supply unit 56, which will be described later, via the external power supply connection section 321.

[0016] A slot 34 may be formed in the front portion 28 of the housing. The slot 34 is an opening from which a circuit board 36, such as an option board, can be inserted and removed. The circuit board 36 inserted into the slot 34 may include a faceplate 38 that covers the slot 34. Note that the circuit board 36 inserted into the slot 34 is not limited to an option board.

[0017] The front portion 28 of the housing may include an air intake section 42. The air intake section 42 may include one or more air inlets that communicate with the housing space 16. The location of the air intake section 42 is not limited to the front portion 28 of the housing.

[0018] The housing panel 44 may be provided as the front part 28 of the housing. In that case, the external connection interface 32 and the air supply unit 42 described above may be provided on the housing panel 44. The housing panel 44 is a panel that can be pulled out.

[0019] Figure 3 is a perspective view showing the state in which the housing panel 44 of the electronic device 10 in Figure 2 is extended.

[0020] The direction in which the housing panel 44 is pulled out intersects with the direction in which the electronic unit 14 is removed. The direction in which the housing panel 44 is pulled out also intersects with the direction from the first housing side portion 261 to the second housing side portion 262. In this embodiment, the direction in which the housing panel 44 is pulled out coincides with the third direction D3 shown in Figure 1. The third direction D3 is perpendicular to the first direction D1 described above, and also perpendicular to the second direction D2.

[0021] The rear portion 30 of the housing is formed in a wall shape to constitute the rear of the housing 12. The rear portion 30 of the housing may be detachable from the bottom portion 20 of the housing. A slot 34 may be formed in the rear portion 30 of the housing, similar to the front portion 28 of the housing. In this case, a circuit board 36 such as an option board may be inserted into the housing space 16 through the slot 34 formed in the rear portion 30 of the housing.

[0022] Furthermore, the rear section 30 of the housing may be equipped with a fan 52. The rear section 30 of the housing may be equipped with multiple fans 52. The fan 52 is an electric fan driven by, for example, a motor (not shown). The fan 52 promotes ventilation of the housing space 16. For example, the fan 52 introduces air into the housing space 16 from the air supply section 42 described above. The fan 52 also discharges air from the housing space 16 through one or more exhaust ports appropriately arranged on the rear section 30 of the housing. At least one fan 52 provided on the rear section 30 of the housing may be detachable from the rear section 30 (exhaust port).

[0023] As described above, the housing 12 houses a plurality of electronic units 14. These plurality of electronic units 14 include a control unit 54 and a power supply unit 56. Within the housing space 16, the control unit 54 and the power supply unit 56 are adjacent to each other. In this embodiment, the second direction D2 described above coincides with the direction from the control unit 54 to the power supply unit 56.

[0024] The control unit 54 is an electronic unit 14 (module) that controls industrial machinery. The control unit 54 comprises multiple circuit boards 36 (see also Figure 8). In other words, the control unit 54 comprises multiple control boards 36C.

[0025] Multiple control boards 36C are interconnected without the use of cables by connectors (not shown) appropriately provided on each of the multiple control boards 36C.

[0026] Multiple control boards 36C are equipped with control circuits. The control circuits are circuits that control industrial machinery. A detailed illustration of the control circuits is omitted, but they include, for example, a processor and memory. The control circuits may also include amplifiers. The amplifiers supply drive current to the industrial machinery based on commands given by the processor. If an option board (circuit board 36) is inserted into the slot 34 described above, the control circuits may be connected to the electronic circuits formed on that option board.

[0027] One of the multiple control boards 36C, control board 36C1, is equipped with a first inter-unit connector 60. The first inter-unit connector 60 is a connector that can be connected to a second inter-unit connector 62, which will be described later. The first inter-unit connector 60 is provided on control board 36C1 so as to face the second direction D2. The out-of-plane direction of control board 36C1 may, but is not limited to, the first direction D1 described above.

[0028] Figure 4 is a perspective view showing the power supply unit 56 in Figure 3.

[0029] The power supply unit 56 is a separate electronic unit 14 (module) from the control unit 54. The power supply unit 56 comprises multiple power circuit boards 36P. Each of the multiple power circuit boards 36P is a circuit board 36 on which a power supply circuit is mounted. The power supply circuit is a circuit that converts power supplied from an external power supply and supplies power to the control unit 54. The power supply circuit and the external power supply are connected via the external power supply connection part 321 described above. A specific illustration of the power supply circuit is omitted, but the power supply circuit may include a current noise filter, a voltage transformer circuit, etc.

[0030] The multiple power circuit boards 36P include power circuit board 36P1, power circuit board 36P2, and power circuit board 36P3. Power circuit boards 36P1 and 36P2 are arranged so that their main surfaces face each other. The in-plane direction of the main surface of power circuit board 36P1 and the in-plane direction of the main surface of power circuit board 36P2 may be parallel. The direction from power circuit board 36P1 to power circuit board 36P2 may coincide with the first direction D1.

[0031] The power circuit board 36P1 is equipped with a power circuit connector 68A. The power circuit connector 68A is a connector 68 that connects the power circuit board 36P1 to another power circuit board 36P (36P3). Multiple power circuit connectors 68A may be provided on the power circuit board 36P1. The orientation of the power circuit connector 68A may be parallel to the in-plane direction of the main surface of the power circuit board 36P1.

[0032] The power circuit board 36P2 is equipped with a power circuit connector 68B. The power circuit connector 68B is a connector 68 that connects the power circuit board 36P2 to another power circuit board 36P (36P3). Multiple power circuit connectors 68B may be provided on the power circuit board 36P2. The orientation of the power circuit connector 68B may be parallel to the in-plane direction of the main surface of the power circuit board 36P2.

[0033] The power circuit board 36P3 is equipped with a plurality of power circuit connectors 70 (70A, 70B). Each of the plurality of power circuit connectors 70 is a connector that can be connected to the power circuit connector 68A of the power circuit board 36P1 or the power circuit connector 68B of the power circuit board 36P2. The plurality of power circuit connectors 70 are arranged on the first main surface 36Sa. The first main surface 36Sa is the main surface of the power circuit board 36P3. More specifically, the first main surface 36Sa is the main surface of the power circuit board 36P3 in the second direction D2.

[0034] Multiple power circuit connectors 70 include power circuit connectors 70A (one or more power circuit connectors 70A) and power circuit connectors 70B (one or more power circuit connectors 70B).

[0035] The power circuit connector 70A is a connector that corresponds to the power circuit connector 68A. The circuits mounted on the power circuit board 36P1 and the circuits mounted on the power circuit board 36P3 are electrically connected via the power circuit connector 68A and the power circuit connector 70A. The power circuit connector 68A and the power circuit connector 70A can be connected without using a cable.

[0036] The power circuit connector 70B is a connector that corresponds to the power circuit connector 68B. The circuits mounted on the power circuit board 36P2 and the circuits mounted on the power circuit board 36P3 are electrically connected via the power circuit connector 68B and the power circuit connector 70B. The power circuit connector 68B and the power circuit connector 70B can be connected without using a cable.

[0037] The power circuit board 36P3 further includes a second inter-unit connector 62. The second inter-unit connector 62 is a connector that can be connected to the first inter-unit connector 60 (control board 36C1). The second inter-unit connector 62 is disposed, for example, on the second main surface 36Sb. The second main surface 36Sb is the back surface of the first main surface 36Sa.

[0038] The first inter-unit connector 60 and the second inter-unit connector 62 can be connected without using a cable. Because the first inter-unit connector 60 and the second inter-unit connector 62 are connected without a cable, the control board 36C1 and the power circuit board 36P3 are connected without a cable. In other words, according to this embodiment, the control unit 54 and the power supply unit 56 are connected without a cable. The control circuit provided in the control unit 54 receives power from the power supply circuit provided in the power supply unit 56 via the first inter-unit connector 60 and the second inter-unit connector 62. This allows the control circuit to operate.

[0039] The disconnection direction for disconnecting the connection between the first inter-unit connector 60 and the second inter-unit connector 62 coincides with the direction from the control circuit board 36C1 toward the power circuit board 36P3. Therefore, in the present embodiment, the disconnection direction coincides with the second direction D2. In other words, the disconnection direction intersects the first direction D1 and also intersects the third direction D3.

[0040] The power supply unit 56 further includes a gripping portion 66. The gripping portion 66 is a portion that can be gripped by a user or the like. The power supply unit 56 may include a plurality of gripping portions 66.

[0041] The gripping portion 66 also serves as a connecting portion (structure) that physically connects the power circuit boards 36P to each other. That is, the gripping portion 66 has a connecting member 58. The connecting member 58 may connect, for example, the power circuit board 36P1 and the power circuit board 36P2.

[0042] For example, studs, screws, pins, etc. arranged so as to be electrically insulated from the above-described power circuit are included in the connecting member 58. At least a part of the connecting member 58 (gripping portion 66) may be formed of an insulating material. A portion of the connecting member 58 formed of an insulating material may be provided as a handle.

[0043] The gripping portion 66 may further include a bracket 72 for supporting the circuit board 36 (power circuit board 36P). As shown in FIG. 4, the bracket 72 is provided on, for example, the power circuit board 36P1 and supports the power circuit board 36P1. The bracket 72 may be connected to a connecting member 58 that connects a plurality of power circuit boards 36P. The gripping portion 66 may further include a connecting member 74 that connects the bracket 72 and the power circuit board 36P. For example, studs, screws, pins, etc. are included in the connecting member 74.

[0044] The above-described electronic device 10 exhibits, for example, the following operational effects.

[0045] Figure 5 is a top view (plan view) of the electronic device 10. Figure 6 is a top view of the electronic device 10 with the housing panel 44 of Figure 5 extended. Figure 7 is a top view of the electronic device 10 with the control unit 54 and power supply unit 56 separated. Note that the housing cover 22 is not shown in each of Figures 5 to 7.

[0046] In this embodiment, the control unit 54 (first electronic unit) and the power supply unit 56 (second electronic unit) are connected by connectors (first unit connector 60, second unit connector 62). The power supply unit 56 includes a plurality of power circuit boards 36P and a gripping portion 66 that connects the plurality of power circuit boards 36P. When a user wants to detach the power supply unit 56 from the control unit 54 housed in the housing 12, they can grasp the gripping portion 66 and pull in the disconnection direction. By pulling the gripping portion 66 that connects the plurality of power circuit boards 36P in the disconnection direction, the entire power supply unit 56 can be detached from the control unit 54 at once. Therefore, a user can quickly perform tasks such as replacing circuit boards on the control unit 54 without disassembling the power supply unit 56 into its plurality of power circuit boards 36P.

[0047] The gripping portion 66 may connect power circuit boards 36P that are not directly connected by connectors (68, 70). For example, the gripping portion 66 may connect power circuit board 36P1 and power circuit board 36P2. By connecting power circuit boards 36P that are not directly connected by connectors, the gripping portion 66 can supplement the structural strength of the power supply unit 56.

[0048] The power circuit board 36P1 and the power circuit board 36P2 may be arranged such that their main surfaces face each other. In this case, the direction from the power circuit board 36P1 toward the power circuit board 36P2 (the first direction D1) and the disconnection direction (the second direction D2) may intersect. A user or the like can grip the power circuit board 36P1 and the power circuit board 36P2 by extending a hand (finger) along the second direction D2. The power circuit board 36P1 and the power circuit board 36P2 arranged such that their main surfaces face each other along the first direction D1 are less likely to hinder a user or the like from gripping the gripping portion 66 along the second direction D2. Also, the power circuit board 36P1 and the power circuit board 36P2 arranged such that their main surfaces face each other along the first direction D1 are less likely to hinder a user or the like from pulling the gripping portion 66 along the second direction D2.

[0049] A user or the like can move the power supply unit 56 in the disconnection direction in a state where the control unit 54 and the power supply unit 56 are housed in the housing 12 (see also FIGS. 5 to 7). In this case, a user or the like can perform an operation on one of the control unit 54 and the power supply unit 56 without taking out both the control unit 54 and the power supply unit 56 from the housing 12.

[0050] The gripping portion 66 is arranged to be electrically insulated from a circuit (power supply circuit) provided in the power supply unit 56. The gripping portion 66 may have insulating properties. Thereby, when a user or the like contacts the gripping portion 66, the risk of the user or the like getting an electric shock is reduced.

[0051] Further, according to the present embodiment, the removal direction of the control board 36C1 through the housing opening 18 from the inside of the housing space 16 to the outside of the housing space 16 intersects the disconnection direction. By doing so, a user or the like of the electronic device 10 can separate the control board 36C1 and the power circuit board 36P3 by relatively moving the control board 36C1 and the power circuit board 36P3 along the disconnection direction. In other words, a user or the like can separate the entire control unit 54 and the entire power supply unit 56 only by relatively moving the control board 36C1 and the power circuit board 36P3 along the disconnection direction.

[0052] Figure 8 is a perspective view of the electronic device 10 showing the control unit 54 being removed from the housing 12 through the housing opening 18.

[0053] Users can easily remove the control board 36C1 (control unit 54), which has been disconnected from the power circuit board 36P3, through the housing opening 18. In this case, the power circuit board 36P3 (power supply unit 56), which is separated from the control board 36C1 along the disconnection direction intersecting the removal direction, is unlikely to obstruct the removal of the control board 36C1 through the housing opening 18.

[0054] The housing side portion 26 may be detachable from the housing bottom portion 20. By removing the housing side portion 26 from the housing bottom portion 20, an opening is formed on the side of the housing 12. At least a part of the power supply unit 56 may protrude from the housing 12 through this opening. This ensures that, regardless of the dimensions of the housing 12 in the direction from the first housing side portion 261 to the second housing side portion 262, there is room to separate the power supply unit 56 (power circuit board 36P3) from the control unit 54 (control board 36C1) along that direction. In other words, according to this embodiment, even if the dimensions of the housing 12 in the second direction D2 are set to the minimum dimensions that can accommodate the control unit 54 and the power supply unit 56, the power supply unit 56 can be sufficiently separated from the control unit 54. Such an electronic device 10 is advantageous in terms of miniaturizing the housing 12. Furthermore, the opening formed on the side of the housing 12 when the housing side portion 26 is removed from the housing bottom portion 20 may be connected to a housing opening 18 that is covered by the housing lid portion 22.

[0055] The housing side portion 26, which is detachable from the housing bottom portion 20, and the housing lid portion 22 may be integrated. This allows the housing side portion 26 to be removed from the housing 12 at the same time as the housing lid portion 22 is removed from the housing 12. This provides convenience for the user.

[0056] Furthermore, according to this embodiment, the housing 12 is provided with a housing panel 44 that can be pulled out along a third direction D3. The third direction D3 intersects with the direction in which the control unit 54 is removed (first direction D1) and also intersects with the direction in which the connection between the control unit 54 and the power supply unit 56 is disconnected (second direction D2). Since the housing panel 44 in the pulled-out state is separated from the control unit 54 and the power supply unit 56, it does not easily interfere with the operation of disconnecting the control unit 54 and the power supply unit 56. Also, since the housing panel 44 in the pulled-out state is separated from the control unit 54, it does not easily interfere with the operation of removing the control unit 54 through the housing opening 18.

[0057] In this embodiment, the control board 36C1, which includes the first inter-unit connector 60, constitutes at least a part of the control unit 54. The power circuit board 36P3, which includes the second inter-unit connector 62, constitutes at least a part of the power supply unit 56. The control unit 54 is an electronic unit 14 that operates using power supplied from the power supply unit 56. After the first inter-unit connector 60 and the second inter-unit connector 62 are separated along the disconnection direction, power cannot be supplied from the power supply unit 56 to the control unit 54. Since power cannot be supplied from the power supply unit 56 to the control unit 54, the user can safely remove the control unit 54 from the housing 12.

[0058] One embodiment may be modified as follows. In the following modifications, explanations that overlap with the embodiment will be omitted as appropriate. Also, in the figures used in the following modifications, components identical to those described in the embodiment will be denoted by the same reference numerals.

[0059] (Modification 1) The control unit 54 (control board 36C1) may be covered with an insulating covering member (first covering member), and the power supply unit 56 (power circuit board 36P3) may be covered with another insulating covering member (second covering member). These multiple covering members (first covering member, second covering member), like the gripping portion 66, reduce the risk of electric shock to the user or others by coming into contact with the control unit 54 or the power supply unit 56.

[0060] (Modification 2) Industrial machinery is not limited to robots. For example, industrial machinery may be machine tools, injection molding machines, etc.
