[0004] In the railway vehicle underfloor device disclosed in Patent Document 1, electrical components, wiring, etc. are attached in advance to the bottom wall, a pair of side walls, and a ceiling wall, respectively, to form subunits. In the railway vehicle underfloor device disclosed in Patent Document 1, the wiring forms subunits together with part of the housing, so when performing work such as wiring installation or maintenance, work inside the subunits or work to disassemble the housing into subunits is required, making the work complicated.

[0005] The present disclosure has been made in consideration of the above circumstances, and aims to provide a wiring device that facilitates work such as wiring and maintenance of electric wires, and a railway vehicle control device having the wiring device.

[0006] To achieve the above object, the present disclosure provides a wiring device that is housed in a housing and is used to route multiple electric wires to an electronic device housed in the housing, and includes a plate-shaped member and multiple guide members. The plate-shaped member is detachably attached to the housing at a position where a distance between one of its two main surfaces, which is adjacent to the inner surface of the housing and faces the inner surface of the housing, and the inner surface of the housing toward which the plate-shaped member faces, is equal to or greater than a threshold value that is greater than the thickness of the thickest electric wire among the multiple electric wires. The multiple guide members are formed on each of the main surfaces of the plate-shaped member and define at least one of the positions and directions of the electric wires on the main surface, guiding the electric wires to the electronic device.

[0007] The wiring device according to the present disclosure includes a plate-shaped member detachably attached to a housing at a position where the distance between the main surface and the inner surface of the housing is equal to or greater than a threshold value that is greater than the thickness of the thickest electric wire, and a plurality of guide members formed on each of the main surfaces of the plate-shaped member define at least one of the position and direction of the electric wires on the main surface, and guide the electric wires to an electronic device. With the above configuration, a wiring device and a railway vehicle control device having a wiring device that facilitates work such as wiring and maintenance of the electric wires can be obtained.

A cross-sectional view of the railway vehicle control device according to an embodiment taken along line IV-IV in FIG. 2. A partial perspective view of a modified example of the railway vehicle control device according to an embodiment.

[0009] Hereinafter, a wiring device and a railway vehicle control device according to an embodiment of the present disclosure will be described in detail with reference to the drawings, in which the same or equivalent parts are designated by the same reference numerals.

[0010] 1 includes electronic devices such as a circuit breaker, a power conversion circuit, and a control circuit that controls switching elements of the power conversion circuit. The control device 1 is installed under the floor of a railway vehicle.

[0011] As shown in Fig. 1, the control device 1 includes a housing 11 that houses electronic devices, and an openable cover 12 that is detachably attached to the housing 11 and covers an opening 11a of the housing 11. In Fig. 1, the Z axis indicates the vertical direction. The Y axis direction is the direction through which the opening 11a penetrates. The X axis extends horizontally along the surface of the housing 11 where the opening 11a is formed. The X axis, Y axis, and Z axis are perpendicular to each other. This also applies to subsequent figures.

[0012] The housing 11 is attached, for example, under the floor of the railway vehicle with the Y-axis direction aligned with the width direction of the railway vehicle. The housing 11 is conductive. Specifically, the housing 11 is formed of a conductor and set to a reference potential. The reference potential is a sufficiently low potential that allows workers to safely perform maintenance and inspection. For example, the housing 11 may be formed of a metal such as aluminum, iron, or stainless steel, and may be grounded.

[0013] 1, the cover 12 is detachably attached to the housing 11 to cover the opening 11a and the area around the opening 11a. The cover 12 is attached to the housing 11 so as to be rotatable about a rotation axis AX1 indicated by a dashed line. This allows the cover 12 to be opened and closed.

[0014] The control device 1 includes a mechanism for attaching the cover 12 to the housing 11, which includes a first member 13 attached to the housing 11 and a second member 14 attached to the cover 12. For example, the control device 1 includes two first members 13 and two second members 14. The first members 13 are attached to the housing 11, for example, by fastening members. The second members 14 are fixed to the cover 12 and engage with the first members 13. Specifically, each second member 14 is detachably attached to the corresponding first member 13 while fixed to the cover 12, and is supported by the first member 13 so as to be rotatable around the rotation axis AX1. The first member 13 and the second member 14 corresponding to the first member 13 form a hinge.

[0015] 2, which is a partially enlarged view of FIG. 1, the control device 1 includes a frame 15 fixed to the housing 11, an electronic device 21 housed in the housing 11, a support member 16 that supports the electronic device 21, and a wiring device 31 housed in the housing 11 and that runs electric wires 41 to the electronic device 21. In FIG. 2, the cover 12, the first member 13, and the second member 14 are omitted from illustration.

[0016] The frame 15 is fixed to the housing 11 by, for example, a fastening member. The frame 15 has a main surface 15a parallel to the YZ plane. The frame 15 has a through-hole 15b that penetrates the frame 15 in the X-axis direction. The frame 15 is preferably made of a conductor. When the frame 15 is made of a conductor and fastened to the housing 11 by a fastening member that is also a conductor, the frame 15 has the same potential as the housing 11. The frame 15 may be made of a metal such as aluminum, iron, or stainless steel.

[0017] The electronic device 21 is, for example, a subrack device that includes a plurality of plug-in units 21a each having a circuit board, a backplane (not shown) having a plurality of slots to which the plug-in units 21a are connected, and a subrack 21b that houses the backplane and the plug-in units 21a connected to the backplane. For example, the electronic device 21 is housed in the housing 11 with the front panel 21c of each plug-in unit 21a facing the opening 11a. An electric wire 41 is connected to the front panel 21c of each plug-in unit 21a.

[0018] The electronic device 21 is detachably fixed to the wiring device 31 by the device fixing member 22. The device fixing member 22 is attached to the wiring device 31 and the electronic device 21, thereby detachably fixing the electronic device 21 to the wiring device 31.

[0019] The device fixing member 22 is formed of a folded flat plate member. A part of the device fixing member 22 is attached to the wiring device 31. Another part of the device fixing member 22 is attached to the vertical upper surface of the electronic device 21. A part of the device fixing member 22 is fixed to the wiring device 31 by a fastening member (not shown) while abutting against the wiring device 31. A part of the device fixing member 22 is fixed to the electronic device 21 by a fastening member (not shown) while abutting against the vertical upper surface of the electronic device 21.

[0020] The support member 16 is fixed to the inner surface 11b of the lower vertical portion of the housing 11 to support the electronic device 21. In this embodiment, the support member 16 is formed of a flat plate member having a main surface parallel to the XY plane. It is preferable that the support member 16 is attached to the housing 11 firmly enough that the relative positional relationship between the support member 16 and the housing 11 does not change due to vibrations caused when the railway vehicle is running. For example, the support member 16 is fixed to the housing 11 by a fastening member.

[0021] The wiring device 31 is housed in the housing 11 and routes a plurality of electric wires 41 to the electronic device 21. As shown in FIG. 3 , which is a diagram in which a portion of the housing 11 is omitted from FIG. 2 , and FIG. 4 , which is a cross-sectional view taken along line IV-IV in FIG. 2 , the wiring device 31 includes a plate-shaped member 32 that is detachably attached to the housing 11, and a plurality of guide members 33a, 33b formed on main surfaces 32a, 32b of the plate-shaped member 32, respectively. The electric wires 41 are not shown in FIG. 4 . The wiring device 31 includes a fixing member 34 that fixes the plate-shaped member 32 to a frame 15 fixed to the housing 11, and a fixing member 35 that fixes the plate-shaped member 32 to the housing 11. The plate-shaped member 32 is formed with an equipment holding member 36 to which the electronic device 21 is attached.

[0022] The plate-like member 32 is detachably attached to the housing 11 at a position where the distance between the inner surface of the housing 11 and the principal surface of both main surfaces 32a, 32b that faces the inner surface of the housing 11 at a position adjacent to the inner surface is equal to or greater than a threshold value that is a value greater than the thickness of the thickest electric wire 41 among the plurality of electric wires 41. Specifically, as shown in Fig. 4, the plate-like member 32 is detachably attached to the housing 11 at a position where the distance between the principal surface 32a and the inner surface 11c at the vertical upper part of the housing 11 is equal to or greater than a threshold value.

[0023] The threshold value is set to a value greater than the thickness of the thickest electric wire 41 among the plurality of electric wires 41. For example, when the thickness of the thickest electric wire 41 is in the range of 30 millimeters or more and 50 millimeters or less, the plate-shaped member 32 is provided at a position where the distance between the main surface 32a and the inner surface 11c is in the range of 60 millimeters or more and 90 millimeters or less. This makes it possible to pass the electric wire 41 between the inner surface 11c and the main surface 32a of the plate-shaped member 32.

[0024] Furthermore, the plate-shaped member 32 is preferably detachably attached to the housing 11 at a position between the housing 11 and the electronic device 21, where the distance between the electronic device 21 and the main surface 32a, 32b facing the electronic device 21 is equal to or greater than a threshold value. Specifically, the plate-shaped member 32 is preferably detachably attached to the housing 11 at a position where the distance between the main surface 32a and the inner surface 11c at the vertical upper part of the housing 11 is equal to or greater than a threshold value, and the distance between the main surface 32b and the electronic device 21 is equal to or greater than a threshold value. In this case, the plate-shaped member 32 is provided at a position where the distance between the main surface 32a and the inner surface 11c and the distance between the main surface 32b and the electronic device 21 are both within the ranges of 60 millimeters or more and 90 millimeters or less. This makes it possible to route the electric wire 41 between the electronic device 21 and the main surface 32b of the plate-shaped member 32.

[0025] The plate-shaped member 32 has a through-hole 32c formed therein, which penetrates the plate-shaped member 32 in a direction intersecting the main surfaces 32a and 32b, for example, in the Z-axis direction. An electric wire 41 is inserted through the through-hole 32c.

[0026] The plate-shaped member 32 is preferably made of a conductor. By electrically connecting the plate-shaped member 32 to the housing 11, which is set to a reference potential, the plate-shaped member 32 has the same potential as the housing 11. For example, the plate-shaped member 32 may be made of a metal such as aluminum, iron, or stainless steel. The main surfaces 32a and 32b are, for example, flat surfaces.

[0027] The plurality of guide members 33a are formed on the main surface 32a. The plurality of guide members 33a define at least one of the arrangement position and arrangement direction of the electric wires 41 on the main surface 32a and guide the electric wires 41 to the electronic device 21. For example, each guide member 33a has a protrusion that protrudes from the main surface 32a in the positive direction of the Z axis. The guide members 33a have a shape that allows the electric wires 41 to be attached, such as an insertion hole through which a binding wire for attaching the electric wires 41 is inserted, a recess into which the electric wires 41 can be fitted, a through-hole through which the electric wires 41 can be inserted, etc.

[0028] The plurality of guide members 33b are formed on the main surface 32b. The plurality of guide members 33b define at least one of the arrangement position and arrangement direction of the electric wires 41 on the main surface 32b and guide the electric wires 41 to the electronic device 21. For example, each guide member 33b has a protrusion that protrudes from the main surface 32b in the negative direction of the Z axis. The guide members 33b have a shape that allows the electric wires 41 to be attached, such as an insertion hole through which a binding wire for attaching the electric wires 41 is inserted, a recess into which the electric wires 41 can be fitted, a through-hole through which the electric wires 41 can be inserted, etc.

[0029] The electric wire 41 is arranged along the protrusions, thereby defining the position and direction of the electric wire 41. Specifically, the horizontal position of the electric wire 41 is defined. Furthermore, the electric wire 41 is attached to the protrusions with a cable tie, thereby defining the vertical position of the electric wire 41. In this way, the guide members 33a, 33b hold the electric wire 41, thereby defining the position and direction of the electric wire 41.

[0030] The guide member 33 a regulates at least one of the position and direction of a portion of the plurality of electric wires 41 , and the guide member 33 b regulates at least one of the position and direction of another portion of the plurality of electric wires 41 .

[0031] 3 and 4 , the fixing member 34 is formed of a folded flat plate member. A portion of the fixing member 34 is attached by abutting against the frame 15, and another portion of the fixing member 34 is attached by abutting against the plate-like member 32. For example, one portion of the fixing member 34 is fixed to the frame 15 by a fastening member (not shown) while abutting against the surface of the frame 15 facing the positive direction of the X-axis. The other portion of the fixing member 34 is fixed to the plate-like member 32 by a fastening member (not shown) while abutting against the main surface 32 a of the plate-like member 32.

[0032] The fixing member 35 is formed of a folded flat plate member. Both ends of the fixing member 35 are attached by abutting against the plate-like member 32, and the central portion of the fixing member 35 is attached by abutting against the housing 11. For example, both ends of the fixing member 35 are fixed to the plate-like member 32 by fastening members (not shown) while abutting against the main surface 32a of the plate-like member 32. The central portion of the fixing member 35 is fixed to the housing 11 by fastening members (not shown) while abutting against the inner surface 11c (at the top of the vertical direction) of the housing 11.

[0033] The fixing member 34 is made of a conductor and electrically connects the plate-shaped member 32 to the frame 15. The fixing member 35 is made of a conductor and electrically connects the plate-shaped member 32 to the housing 11. The plate-shaped member 32 is electrically connected to the housing 11 and the frame 15, which has the same potential as the housing 11, and thus has the same potential as the housing 11.

[0034] The equipment-holding member 36 has a flat plate-like shape extending in the negative direction of the Z axis from the main surface 32b of the plate-shaped member 32. The equipment fixing member 22 is attached to the surface of the equipment-holding member 36 facing in the negative direction of the Y axis.

[0035] The electric wires 41 are routed between the underfloor of the railway vehicle and the vertical upper surface 11d of the housing 11, then drawn into the interior of the housing 11, and attached to the protrusion of the guide member 33a or the protrusion of the guide member 33b. Specifically, some of the plurality of electric wires 41 are arranged along the main surface 32a, bypassing the through-holes 32c, and attached to the protrusion of the guide member 33a. Other parts of the plurality of electric wires 41 pass through the through-holes 32c, are arranged along the main surface 32b, and are attached to the protrusion of the guide member 33b.

[0036] For example, among the plurality of electric wires 41, the electric wire 41 serving as a power line passes through the through hole 32 c, is arranged along the main surface 32 b, and is attached to the protrusion of the guide member 33 b. Among the plurality of electric wires 41, the electric wire 41 serving as a signal line is arranged along the main surface 32 a, bypassing the through hole 32 c, and is attached to the protrusion of the guide member 33 a. By arranging the electric wire 41 serving as a power line and the electric wire 41 serving as a signal line with the metal plate-like member 32 sandwiched therebetween as described above, it is possible to reduce the effect of electromagnetic noise emitted from the power line on the signal line.

[0037] The above-described arrangement of the electric wires 41 is performed before the wiring device 31 is fixed to the housing 11. In other words, the arrangement of the electric wires 41 is performed before the plate-shaped member 32 is attached to the frame 15 and the housing 11 by the fixing members 34, 35. Specifically, the wiring device 31 is formed by arranging the electric wires 41 along the main surfaces 32a, 32b of the plate-shaped member 32, attaching the electric wires 41 to the guide members 33a, 33b, and then attaching the fixing members 34, 35 to the plate-shaped member 32. The wiring device 31 is inserted into the housing 11 through the opening 11a, and the fixing members 34, 35 attached to the plate-shaped member 32 are attached to the frame 15 and the housing 11, respectively, thereby attaching the wiring device 31 to the housing 11. This eliminates the need to perform the work of installing the electric wires 41 inside the housing 11, simplifying the manufacturing process of the control device 1.

[0038] As described above, the wiring device 31 according to the embodiment includes a plate-shaped member 32 that is detachably attached to the housing 11. The electric wires 41 are attached to guide members 33a, 33b formed on the main surfaces 32a, 32b of the plate-shaped member 32. Because the plate-shaped member 32 is detachable, the electric wires 41 can be installed before the plate-shaped member 32 is installed in the housing 11, and the electric wires 41 can be maintained after the plate-shaped member 32 is removed from the housing 11. This facilitates installation, maintenance, and other tasks for the electric wires 41. Because the electric wires 41 are installed on both sides of the plate-shaped member 32, specifically along the main surfaces 32a, 32b, the spacing between adjacent electric wires 41 can be increased compared to when the electric wires 41 are installed on one side. This reduces the impact of electromagnetic noise emitted from the power supply line on the signal line. As a result, the EMC (Electromagnetic Compatibility) requirements required for the control device 1 installed in a railway vehicle can be met.

[0039] When the plate-shaped member 32 is formed of metal, the electric wire 41 serving as the power supply line and the electric wire 41 serving as the signal line are arranged on either side of the plate-shaped member 32, thereby making it possible to further reduce the impact of electromagnetic noise emitted from the power supply line on the signal line.

[0040] The present disclosure is not limited to the above-described embodiment. The structure and shape of the plate-shaped member 32 are not limited to the above-described example, and may be any structure and shape as long as the electric wires 41 can be arranged on both main surfaces 32 a, 32 b and the plate-shaped member 32 can be detachably attached to the housing 11. As an example, the main surfaces 32 a, 32 b of the plate-shaped member 32 may be curved.

[0041] The mounting position of the plate-shaped member 32 is not limited to the above example, and may be any mounting position as long as it allows the electric wires 41 to be arranged on both main surfaces 32a, 32b. As an example, the plate-shaped member 32 may be mounted on the inner surface 11b of the housing 11. In this case, it is sufficient that the distance between the main surface 32b of the plate-shaped member 32 and the inner surface 11b is equal to or greater than a threshold value. For example, the distance between the main surface 32b of the plate-shaped member 32 and the inner surface 11b may be within the range of 60 millimeters or more and 90 millimeters or less.

[0042] The position and shape of the through hole 32c in the plate-shaped member 32 are arbitrary as long as they allow some of the electric wires 41 to be guided from one of the main surfaces 32a, 32b to the other of the main surfaces 32a, 32b. As an example, the plate-shaped member 32 may have a notch as the through hole 32c.

[0043] The guide members 33a, 33b may be formed at any position and in any shape as long as they can define at least one of the position and direction of the wires 41. As one example, the guide members 33a may be formed at irregular intervals on the main surface 32a. As another example, the guide members 33a, which are protrusions, may be formed integrally with the plate-like member 32. As another example, the guide members 33a may be grooves formed on the main surface 32a. The same applies to the guide members 33b.

[0044] The shape, attachment position, and attachment method of the fixing members 34, 35 are not limited to the above examples, and any shape, attachment position, and attachment method may be used as long as they allow the plate-shaped member 32 to be detachably fixed to the housing 11. As one example, the fixing member 34 may have the same shape as the fixing member 35 and be attached directly to the housing 11. As another example, the fixing member 34 may be fixed to the frame 15 and the plate-shaped member 32 by fitting. Similarly, the fixing member 35 may be fixed to the housing 11 and the plate-shaped member 32 by fitting. As another example, the fixing member 35 may be fixed to another frame provided inside the housing 11.

[0045] The fixing members 34, 35 may be permanently fixed to the plate-like member 32 and detachably attached to the frame 15 and the housing 11. As an example, the fixing members 34, 35 may be formed integrally with the plate-like member 32, or may be attached to the plate-like member 32 by an attachment method such as bonding with an adhesive or welding.

[0046] Alternatively, the fixing members 34, 35 may be permanently fixed to the frame 15 and the housing 11, and may be detachably attached to the plate-like member 32. As an example, the fixing members 34, 35 may be attached to the frame 15 and the housing 11 by adhesive bonding, welding, or other attachment methods.

[0047] As shown in Fig. 5, locking members 17 having a shape that allows plate-shaped members 32 to be locked may be provided inside the housing 11. In the example of Fig. 5, the control device 1 includes a pair of locking members 17 fixed to the inner surface 11c of the housing 11. One end of each locking member 17 is fixed to the inner surface 11c, and the other end of each locking member 17 allows the plate-shaped member 32 to be locked. By providing a pair of locking members 17, it is possible to attach the fixing members 34, 35 attached to the plate-shaped member 32 to the housing 11 and the frame 15 with the plate-shaped member 32 locked to the pair of locking members 17. This facilitates the process of fixing the plate-shaped member 32 to the housing 11.

[0048] As another example, a frame having a main surface parallel to the XZ plane may be provided inside the housing 11, and a locking member that is a plate-like member extending horizontally from the frame may be formed.

[0049] The present disclosure allows various embodiments and modifications without departing from the broad spirit and scope of the present disclosure. Furthermore, the above-described embodiments are intended to illustrate the present disclosure and do not limit the scope of the present disclosure. That is, the scope of the present disclosure is defined by the claims, not the embodiments. Various modifications made within the scope of the claims and the meaning of equivalent disclosures are considered to be within the scope of the present disclosure.
