Description

[Technical Field]

[0001] The technology disclosed in this specification relates to a device including a plurality of electrical components, and more particularly to a wiring structure within a device including a plurality of electrical components. [Background technology]

[0002] In a device equipped with multiple electrical components, a housing is provided to house the electrical components, and the multiple electrical components are installed inside the housing, along with wiring connected to these electrical components (for example, power lines that supply power to each electrical component, signal lines for communication between the multiple electrical components, etc.). For example, Patent Document 1 discloses a wiring structure within a device that houses multiple electrical components. The device in Patent Document 1 is a control panel, and is configured with an opening on the front. During maintenance, etc., a worker opens a door attached to the front to access the inside of the device. In the device in Patent Document 1, the wiring is arranged below the electrical components.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-208369 Summary of the Invention [Problem to be solved by the invention]

[0004] Because the device in Patent Document 1 is a control panel, it has a small depth, and no other electrical components are arranged behind the electrical components. However, some devices have a relatively large depth width, and multiple electrical components are arranged side by side in the depth direction. When wiring is arranged below the electrical components, as in the device in Patent Document 1, during maintenance, when removing electrical components located at the back side as seen from the opening from the housing, the wiring arranged on the opening side (i.e., the front side) gets in the way. For this reason, it was necessary to remove the wiring arranged on the opening side from the housing before removing the electrical components.

[0005] This specification discloses a technique for making it easier to remove electrical components from within a device. [Means for solving the problem]

[0006] The device disclosed in this specification includes a plurality of electrical components, a housing that houses the plurality of electrical components and has an opening through which the electrical components can be removed, wherein when viewed from the opening, at least one of the plurality of electrical components is positioned behind the other electrical components, a plurality of wires connected to the electrical components, and a plurality of support members that support the wires within the housing, the support members being installed so as to support the wires at a position where the wires do not overlap with the plurality of electrical components on the opening side when the plurality of electrical components and the plurality of wires are viewed from the opening.

[0007] In the above device, the support member supports the multiple wirings so that, when viewed from the opening, the wirings do not overlap with the multiple electrical components on the opening side. This reduces the interference caused by the wiring when moving the electrical components from the opening to the outside of the housing. This makes it easier to remove the electrical components from the housing. [Brief explanation of the drawings]

[Figure 3] FIG. 2 is a diagram for explaining the arrangement of power lines and signal lines inside a housing. [Figure 4] FIG. 4 is a side view of the power supply line and the signal line inside the housing as viewed from the opening. [Figure 5] FIG. 10 is a diagram showing a state in which electrical components taken out of the housing are connected to power lines and signal lines via extension wiring. DETAILED DESCRIPTION OF THE INVENTION

[0009] The main features of the embodiments described below are listed below. Note that the technical elements described below are independent technical elements that exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.

[0010] In the device disclosed herein, the opening may be provided on a side surface of the housing. The multiple support members may support the multiple wirings so that the wirings extend along the top surface of the housing and extend downward above the electrical equipment. With this configuration, since the opening is provided on the side surface of the housing, the electrical equipment can be removed sideways. Since the wirings extend along the top surface, the wirings are less likely to get in the way when the electrical equipment is removed sideways.

[0011] In the device disclosed herein, the multiple wirings may include power lines that supply power to the electrical components and signal lines that communicate signals between the multiple electrical components. The multiple support members may support the power lines so that the power lines extend along a first line when the device is viewed from above, and may support the signal lines so that the signal lines extend along a second line different from the first line. With this configuration, the power lines and the signal lines are arranged on different lines, providing a relatively large space between the power lines and the signal lines. This reduces the likelihood of noise from the power lines being generated in the signal lines.

[0012] In the device disclosed in this specification, the multiple wirings may include one or more power lines that supply power to the electrical components and one or more signal lines that communicate signals between the multiple electrical components. The multiple support members may support the power lines at a first height and support the signal lines at a second height different from the first height. With this configuration, the power lines and the signal lines are arranged at different heights, providing a relatively large space between them. This reduces the likelihood of noise from the power lines being generated in the signal lines.

[0013] In the device disclosed in this specification, each of the multiple support members may be a frame member having a recess. The multiple wiring may be disposed in the recess. The multiple support members may be installed at intervals. With this configuration, by disposing the wiring in the recess of each frame member, it becomes easier to properly support the wiring and to easily dispose the wiring in the recess of the frame. Furthermore, by disposing the multiple frame members at intervals, it becomes easier to extend the wiring downward between adjacent frame members, making it easier to connect the wiring to electrical components.

[0014] In the device disclosed in this specification, a specific wire among the multiple wires may have a connection portion connected to a specific electrical component among the multiple electrical components. The connection portion of the specific wire may be connectable to another extension wire. When the specific electrical component is removed from the housing, the specific wire may be connectable to the specific wire via the other extension wire. With this configuration, the specific electrical component can be connected to the specific wire within the housing via the other extension wire. Therefore, it is possible to perform tasks such as setting up the specific electrical component and checking its operation while the specific electrical component is removed from the housing. [Example]

[0015] An apparatus 10 according to an embodiment will be described with reference to the drawings. As shown in FIG. 1, the apparatus 10 includes multiple electrical components 12, a housing 14 that houses the multiple electrical components 12, wiring 20 connected to the electrical components 12, and multiple support members 30 that support the wiring 20. Note that in FIG. 1, for ease of viewing, the housing 14 is indicated by a dashed line, allowing the internal configuration of the housing 14 to be seen. Also, only a portion of the multiple support members 30 and multiple support columns 18 (described later) are shown, with the rest omitted. In this embodiment, the apparatus 10 is a manufacturing apparatus that produces three-dimensional electronic modules using inkjet technology to perform base molding, circuit printing, component bonding bump formation, adhesive application, and other processes. Typically, the apparatus 10 is arranged alongside other apparatuses (e.g., a component mounter that mounts components on a substrate) to form a single production line. When incorporated into a production line, other apparatuses are often arranged on one of the two sides (i.e., two surfaces parallel to the XZ plane) of the apparatus 10, and access from the front and rear is often difficult. Therefore, the electrical components 12 inside the device 10 are accessed from one side of the device 10. Note that the technology of this embodiment can be applied to any device that houses multiple electrical components in a housing, and there is no particular limitation on the type of device.

[0016] The housing 14 is shaped like a rectangular parallelepiped box and accommodates multiple electrical components 12 therein. An opening 16 is provided on one of the four side surfaces of the housing 14 (in FIG. 1, the side surface on the +Y direction side parallel to the XZ plane). The multiple electrical components 12 can be removed through the opening 16. That is, the multiple electrical components 12 can be removed from the inside of the housing 14 to the outside by moving them in the +Y direction through the opening 16. As shown in FIG. 1, the multiple electrical components 12 are arranged side by side in the lateral direction (X direction) within the housing 14 and also arranged side by side in the depth direction (Y direction) as viewed from the opening 16. Therefore, when looking inside the housing 14 from the opening 16, another electrical component 12 is arranged behind (on the -Y direction side) the electrical component 12 arranged in the front (on the +Y direction side). A plurality of support columns 18 are arranged within the housing 14 along the inner surfaces (specifically, the top and side surfaces) of the housing 14. 1, for ease of viewing, only two of the multiple support columns 18 are shown, and the others are not shown. The support columns 18 are arranged to maintain the shape of the housing 14. The support columns 18 are also used to install support members 30, which will be described later.

[0017] The wiring 20 is arranged inside the housing 14 and connected to the electrical components 12. Examples of the wiring 20 include a power line 22 and a signal line 24. The power line 22 connects a power source (not shown) to the electrical components 12 and supplies power to the electrical components 12. The signal line 24 connects multiple electrical components 12 and communicates signals between the multiple electrical components 12. The power line 22 and the signal line 24 are supported by a support member 30. Specifically, the power line 22 and the signal line 24 are supported by the support member 30 and arranged along the top surface of the housing 14. Furthermore, the power line 22 and the signal line 24 arranged along the top surface of the housing 14 are arranged above the electrical components 12, from near the top surface of the housing 14 downward. The arrangement of the power line 22 and the signal line 24 will be described in detail later.

[0018] The support member 30 is disposed within the housing 14 and supports the power line 22 and the signal line 24. The support member 30 is a frame material and is attached to the support column 18. Specifically, the support member 30 is installed on the support column 18 that is disposed along the top surface of the housing 14. A plurality of support members 30 are disposed at intervals along the axis of the support column 18, so that the power line 22 and the signal line 24 are disposed along the top surface of the housing 14. Note that in FIG. 1, for ease of viewing the drawing, only some of the plurality of support members 30 are shown, and the others are not shown, but the plurality of support members 30 are also disposed along the power line 22 and the signal line 24 that are disposed along the top surface of the housing 14 in FIG. 1.

[0019] As shown in FIG. 2 , the support member 30 includes a fixing portion 32 that fixes the support member 30 to the support column 18 and a support portion 36 that supports the wiring 20 (i.e., the power line 22 or the signal line 24). The fixing portion 32 is flat and is fastened to the upper surface of the support column 18 using a fastening member 34. The support portion 36 is generally U-shaped and has a recess 37. One end of the support portion 36 is connected to the fixing portion 32. The wiring 20 (i.e., the power line 22 or the signal line 24) is placed in the recess 37. The power line 22 and the signal line 24 are each supported by a separate support member 30. The recess 37 in the support portion 36 allows the wiring 20 to be supported by the support member 30 without falling off the support member 30. One end of the support portion 36 is connected to the fixing portion 32, while the other end is open. This allows the wiring 20 to be placed in the recess 37 of the support portion 36 from the other end side of the support portion 36. Therefore, the wiring 20 can be easily placed on the support portion 36.

[0020] Furthermore, the support member 30 is mounted on a support column 18 that is disposed along the upper surface of the housing 14. As a result, the wiring 20 is disposed so as to extend along the support column 18 and also along the upper surface of the housing 14. As shown in FIG. 1 , when the wiring 20 is disposed along the upper surface of the housing 14, the wiring 20 can be easily disposed so as not to be positioned in front of the electrical component 12 when viewed from the opening 16. By not disposing the wiring 20 in a position that is in front of the electrical component 12 when viewed from the opening 16, the wiring 20 can be prevented from getting in the way when the electrical component 12 is removed from the housing 14 for maintenance or the like. Therefore, the electrical component 12 can be removed from the housing 14 without removing the wiring 20 to the outside of the housing 14.

[0021] 1, the multiple support members 30 are arranged at intervals. The number of support members 30 arranged within the housing 14 is not particularly limited as long as the number of support members 30 is sufficient to support the wiring 20 and are arranged at positions where the wiring 20 can be supported. The wiring 20 is arranged downward from near the top surface of the housing 14 above the electrical component 12 to be connected to the connection portion (connector portion) of the electrical component 12. In positions where no support members 30 are arranged (positions between adjacent support members 30), the wiring 20 can extend downward. By arranging the multiple support members 30 at intervals along the support pillar 18, it becomes easier to extend the wiring 20 downward in positions where the electrical component 12 is arranged.

[0022] The arrangement of the wiring 20 will now be described. Specifically, the arrangement of the power line 22 and the signal line 24 will be described. As shown in FIG. 3, the power line 22 and the signal line 24 are arranged to extend along different lines. Note that in FIG. 3, the electrical components 12, the support posts 18, and the support member 30 are not shown to make the drawing easier to understand. The power line 22 and the signal line 24 each extend in the X direction. The position of the power line 22 extending in the X direction in the Y direction (depth direction) is different from the position of the signal line 24 extending in the X direction in the Y direction (depth direction). In FIG. 3, the power line 22, the signal line 24, the signal line 24, and the power line 22 are arranged in this order from the front to the back (from the +Y direction to the −Y direction). By arranging the power line 22 and the signal line 24 on different lines, the power line 22 and the signal line 24 are arranged close to each other and contact between them can be prevented. Therefore, it is possible to suppress noise from being generated in the signal line 24 from the power line 22 .

[0023] 4, the power supply line 22 and the signal line 24 are arranged at different heights. Specifically, the signal line 24 is supported at a higher position than the power supply line 22. By arranging the power supply line 22 and the signal line 24 at different heights, a space is formed between the power supply line 22 and the signal line 24 at the intersection of the power supply line 22 and the signal line 24, and the power supply line 22 and the signal line 24 can be arranged without contacting each other. This makes it possible to suppress noise from the power supply line 22 from being generated in the signal line 24.

[0024] In this embodiment, the signal line 24 is supported at a higher position than the power line 22, but the signal line 24 may be supported at a lower position than the power line 22. Furthermore, although the support member 30 supports the power line 22 and the signal line 24 so that they are arranged on different lines, this configuration is not limiting. The support member may also support the power line 22 and the signal line 24 so that they are arranged at different heights on the same line. Even when the power line 22 and the signal line 24 are arranged in this manner, by forming a space between the power line 22 and the signal line 24, the power line 22 and the signal line 24 can be arranged so that they do not come into contact with each other, and noise from the power line 22 can be suppressed from being generated in the signal line 24.

[0025] 5, the power line 22 and the signal line 24 can be connected to an extension wiring 26 such as an extension cable. For example, the power line 22 and the signal line 24 located near the opening 16 can be connected to the extension wiring 26. The extension wiring 26 is configured so that one end can be connected to the connection portion 23 at the end of the power line 22 and the other end can be connected to a connection portion (not shown) for connecting the power line 22 of the electrical component 12. The extension wiring 26 is also configured so that one end can be connected to the connection portion 25 at the end of the signal line 24 and the other end can be connected to a connection portion (not shown) for connecting the signal line 24 of the electrical component 12. The electrical component 12 taken out of the housing 14 can be connected to the power line 22 and the signal line 24 inside the housing 14 via the extension wiring 26. When the electrical component 12 is taken out of the housing 14 for maintenance or the like, the taken-out electrical component 12 cannot be directly connected to the power line 22 and the signal line 24 inside the housing 14. By connecting the electrical component 12 outside the housing 14 to the power line 22 and the signal line 24 inside the housing 14 via the extension wiring 26, the electrical component 12 taken out of the housing 14 is connected to the other electrical components 12 inside the housing 14 via the extension wiring 26, the power line 22, and the signal line 24. This makes it possible to perform tasks such as setting up the electrical component 12 and checking its operation while the electrical component 12 is taken out of the housing 14. Therefore, it is possible to properly set up the electrical component 12 and check that the electrical component 12 is operating properly before returning the electrical component 12 taken out of the housing 14 to the housing 14.

The technology described in the claims includes various modifications and variations of the specific examples exemplified above. Furthermore, the technical elements described in this specification or drawings exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.
