Description of the embodiments A wiring device and a rail vehicle control device according to embodiments of the present disclosure are described in detail below with reference to the drawings. Identical or corresponding components are identified in the drawings by the same reference numerals. A railway vehicle control device (hereinafter simply referred to as the control device) 1, as illustrated in Fig. 1, comprises an electronic device, such as a circuit breaker, a power conversion circuit, and a control circuit that controls switching elements in the power conversion circuit. The control device 1 is installed under the floor of a railway vehicle. As illustrated in Fig. 1, the control device 1 comprises a housing 11, which accommodates an electronic device, and an openable and closable cover 12, which is detachably mounted on the housing 11 and covers an opening 11a of the housing 11. In Fig. 1, the Z-axis indicates the vertical direction. The direction of penetration of the opening 11a is defined as the Y-axis direction. The X-axis extends horizontally along a surface where the opening 11a of the housing 11 is formed. The X-axis, Y-axis, and Z-axis are orthogonal to each other. The same applies to the following figures. The housing 11 is mounted on the underbody of the rail vehicle, for example, in a direction in which the Y-axis is aligned with a lateral direction of the rail vehicle. The housing 11 is electrically conductive. In particular, the housing 11 is made of a conductor and grounded to a reference potential. The reference potential is sufficiently low to allow maintenance personnel to safely carry out maintenance and inspection work. For example, it is sufficient to manufacture the housing 11 from a metal such as aluminum, iron, or stainless steel and to ground it. As illustrated in Fig. 1, the cover 12 is detachably mounted on the housing 11 and covers the opening 11a and a periphery or edge of the opening 11a. The cover 12 is rotatably mounted on the housing 11 about a rotation axis AX1, indicated by a dashed line. This allows the cover 12 to be opened and closed. The control device 1 comprises, as a mechanism for mounting the cover 12 to the housing 11, a first link 13 mounted on the housing 11 and a second link 14 mounted on the cover 12. For example, the control device 1 comprises two first links 13 and two second links 14. The first links 13 are mounted on the housing 11, for example, by fastening elements. The second links 14 are attached to the cover 12 and engage with the first links 13. In particular, if every second link 14 is attached to the cover 12, each second link 14 is detachably mounted on the corresponding first link 13 and is rotatably supported by the first link 13 about the axis of rotation AX1. The first links 13 and the second links 14 corresponding to the first links 13 form a hinge. As illustrated in Fig. 2, which is a partially enlarged view of Fig. 1, the control device 1 comprises a frame 15 attached to the housing 11, an electronic device 21 housed in the housing 11, a support member 16 supporting the electronic device 21, and a wiring device 31 housed in the housing 11 to guide an electrical wire 41 to the electronic device 21. In Fig. 2, the cover 12, the first member 13, and the second member 14 are omitted. The frame 15 is attached to the housing 11, for example, by a fastening element. The frame 15 comprises a main surface 15a parallel to the YZ plane. The frame 15 has a through-hole 15b extending through the frame 15 in the X-axis direction. Preferably, the frame 15 is formed from a conductor. By being formed from a conductor and being attached to the housing 11 by conductive fastening elements, the frame 15 is brought to the same electrical potential as the housing 11. The frame 15 can, for example, be made of a metal such as aluminum, iron, or stainless steel. The electronic device 21 can, for example, be a subrack system comprising a plurality of plug-in units 21a, each having a printed circuit board, a backplane (not shown) with a plurality of slots to which the plug-in units 21a are connected, and a subrack 21b that accommodates the backplane and the plug-in units 21a connected to it. For example, the electronic device 21 is housed in the enclosure 11, with a front panel 21c of each plug-in unit 21a facing the opening 11a. The electrical wire 41 is connected to the front panel 21c of each plug-in unit 21a. The electronic device 21 is detachably attached to the wiring device 31 by a device fastening element 22. The device fastening element 22 is mounted on both the wiring device 31 and the electronic device 21 in order to detachably attach the electronic device 21 to the wiring device 31. The device mounting element 22 is formed from a curved flat plate segment. One section of the device mounting element 22 is mounted on the wiring device 31. Another section of the device mounting element 22 is mounted on the vertically upper surface of the electronic device 21. One section of the device mounting element 22 is attached to the wiring device 31 by a fastening element (not shown) in a state of contact with the wiring device 31. Another section of the device mounting element 22 is attached to the electronic device 21 by a fastening element (not shown) in a state of contact with the vertically upper surface of the electronic device 21. The support member 16 is attached to an inner surface 11b of a vertically lower section of the housing 11 to support the electronic device 21. In this embodiment, the support member 16 is formed from a flat plate member having a main surface parallel to the XY plane. Preferably, the support member 16 is attached to the housing 11 so firmly that the relative position between the support member 16 and the housing 11 remains unchanged during vibrations while a rail vehicle is in motion. The support member 16 is attached to the housing 11, for example, by a fastening element. The wiring device 31 is housed in the casing 11 and leads a plurality of electrical wires 41 to the electronic device 21. As illustrated in Fig. 3, which omits the parts of the casing 11 from Fig. 2 and Fig. 4 (a sectional view along line IV-IV in Fig. 2), the wiring device 31 comprises a plate-shaped element 32 detachably mounted on the casing 11 and a plurality of guide elements 33a and 33b formed on the main surfaces 32a and 32b of the plate-shaped element 32. The electrical wires 41 are omitted in Fig. 4. The wiring device 31 comprises a fastening element 34 for attaching the plate-shaped element 32 to the frame 15 attached to the housing 11 and a fastening element 35 for attaching the plate-shaped element 32 to the housing 11. The plate-shaped element 32 is formed with a device retaining element 36 on which the electronic device 21 is mounted. The plate-shaped element 32 is detachably mounted on the housing 11 in a position where the distance between an inner surface of the housing 11 and one of the two main surfaces 32a and 32b, which face the inner surface of the housing 11 in an adjacent position, is greater than or equal to the threshold value, which is greater than the diameter of an electrical wire 41 that is thickest among the plurality of electrical wires 41. In particular, as illustrated in Fig. 4, the plate-shaped element 32 is detachably mounted on the housing 11 in a position where the distance between the main surface 32a and an inner surface 11c of a vertically upper section of the housing 11 is greater than or equal to the threshold value. The threshold value is set such that it is larger than the diameter of the thickest electrical wire 41 from the plurality of electrical wires 41. If, for example, the diameter of the thickest electrical wire 41 is within a range of 30 mm to 50 mm inclusive, the plate-shaped element 32 is positioned where the distance between the main surface 32a and the inner surface 11c is within a range of 60 mm to 90 mm inclusive. This allows the electrical wires 41 to be guided between the inner surface 11c and the main surface 32a of the plate-shaped element 32. Preferably, the plate-shaped element 32 is detachably mounted on the housing 11 in a position between the housing 11 and the electronic device 21, where the distance between the electronic device 21 and one of the two main surfaces 32a and 32b facing the electronic device 21 is greater than or equal to the threshold value. In particular, the plate-shaped element 32 is preferably detachably mounted on the housing 11 in a position where the distance between the main surface 32a and the inner surface 11c of the vertically upper section of the housing 11 is greater than or equal to a threshold value, and where the distance between the main surface 32b and the electronic device 21 is greater than or equal to the threshold value.In this case, the plate-shaped element 32 is positioned such that 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 each within a range of 60 mm to 90 mm inclusive. This allows the electrical wires 41 to be routed between the electronic device 21 and the main surface 32b of the plate-shaped element 32. The plate-shaped member 32 has a through-hole 32c extending through the plate-shaped member 32 in a direction that intersects the main surfaces 32a and 32b, for example in the Z-axis direction. The electrical wires 41 are inserted through the through-hole 32c. Preferably, the plate-shaped element 32 is formed from a conductor. By being electrically connected to the housing 11, which is set to a reference potential, the plate-shaped element 32 is brought to the same electrical potential as the housing 11. The plate-shaped element 32 can, for example, be made of a metal such as aluminum, iron, or stainless steel. The main surfaces 32a and 32b are, for example, flat surfaces. The multiple guide elements 33a are formed on the main surface 32a. The guide elements 33a define the placement position and / or the placement direction of the electrical wires 41 on the main surface 32a and guide the electrical wires 41 to the electronic device 21. For example, each guide element 33a includes a projection that extends from the main surface 32a in the positive Z-axis direction. The guide element 33a has a shape that allows for the fastening of the electrical wire 41, such as an insertion hole through which a binding wire is inserted to fasten the electrical wire 41, a recess into which the electrical wire 41 can be fitted, or a through-hole through which the electrical wire 41 can be inserted. The plurality of guide elements 33b are formed on the main surface 32b. The guide elements 33b define the placement position and / or the placement direction of the electrical wires 41 on the main surface 32b and guide the electrical wires 41 to the electronic device 21. For example, each guide element 33b includes a projection that extends from the main surface 32b in the negative Z-axis direction. The guide element 33b has a shape that allows for the fastening of the electrical wire 41 and includes, for example, an insertion hole through which a binding wire is inserted to fasten the electrical wire 41, a recess into which the electrical wire 41 can be fitted, or a through-hole through which the electrical wire 41 can be inserted. By arranging the electrical wire 41 along the projection, its placement position and direction are defined. In particular, its horizontal position is defined. Furthermore, by securing the electrical wire 41 to the projection with a binding band, its vertical position is defined. In this way, by holding the electrical wire 41 with each of the guide members 33a and 33b, its placement position and direction are defined. The guide elements 33a regulate or determine the placement position and / or the placement direction of a subset of the plurality of electrical wires 41, and the guide elements 33b regulate or determine the placement position and / or the placement direction of another subset of the plurality of electrical wires 41. As illustrated in Figures 3 and 4, the fastening member 34 is formed from a curved, flat plate member. One section of the fastening member 34 is in contact with and mounted to the frame 15, and another section of the fastening member 34 is in contact with and mounted to the plate member 32. For example, one section of the fastening member 34 is attached to the frame 15 by a fastening member (not shown) in a state where it is in contact with the surface of the frame 15 facing the positive X-axis direction. Another section of the fastening member 34 is attached to the plate member 32 by a fastening member (not shown) in a state where it is in contact with the main surface 32a of the plate member 32. The fastening element 35 is formed from a curved, flat plate element. Both end sections of the fastening element 35 are in contact with and mounted to the plate-shaped element 32, and the middle section of the fastening element 35 is in contact with and mounted to the housing 11. For example, both ends of the fastening element 35 are attached to the plate-shaped element 32 by fastening elements (not illustrated) in a state where they are in contact with the main surface 32a of the plate-shaped element 32. The middle section of the fastening element 35 is attached to the housing 11 by a fastening element (not illustrated) in a state where it is in contact with the inner surface 11c of the vertically upper section of the housing 11. The fastening element 34 is formed from a conductor and electrically connects the plate-shaped element 32 to the frame 15. The fastening element 35 is formed from a conductor and electrically connects the plate-shaped element 32 to the housing 11. By electrically connecting the housing 11 to the frame 15, which has the same electrical potential as the housing 11, the plate-shaped element 32 is brought to the same electrical potential as the housing 11. The device holding element 36 comprises a flat plate shape that extends in the negative Z-axis direction from the main surface 32b of the plate-shaped element 32. The device fastening element 22 is mounted on a surface of the device holding element 36 that faces the negative Y-axis direction. The electrical wire 41 is guided into the housing 11 between the underbody of the rail vehicle and the vertical top 11d of the housing 11 and mounted on the projection of the guide member 33a or on the projection of the guide member 33b. Specifically, a portion of the plurality of electrical wires 41 is arranged along the main surface 32a, bypassing the through-hole 32c, and is attached to the projection of the guide member 33a. Another portion of the plurality of electrical wires 41 is arranged along the main surface 32b through the through-hole 32c and is attached to the projection of the guide member 33b. For example, of the multitude of electrical wires 41, the electrical wire 41 serving as a current conductor is arranged along the main surface 32b through the through-hole 32c and attached to the projection of the guide member 33b. Of the multitude of electrical wires 41, the electrical wire 41 serving as a signal conductor is arranged along the main surface 32a bypassing the through-hole 32c and attached to the projection of the guide member 33a. By arranging the electrical wire 41 serving as a current conductor and the electrical wire 41 serving as a signal conductor on opposite sides of the plate-shaped member 32, made of metal as described above, the effects of electromagnetic noise emitted from the current conductor to the signal conductor can be reduced. The electrical wires 41 described above are arranged before the wiring device 31 is attached to the housing 11. In other words, the electrical wires 41 are arranged before the plate-shaped link 32 is mounted to the frame 15 and the housing 11 via the mounting elements 34 and 35. Specifically, the electrical wires 41 are arranged along the main surfaces 32a and 32b of the plate-shaped link 32 and attached to the guide elements 33a and 33b. Subsequently, the mounting elements 34 and 35 are mounted to the plate-shaped link 32 to form the wiring device 31. The wiring device 31 is inserted into the housing 11 through the opening 11a, and the mounting elements 34 and 35, which are attached to the plate-shaped link 32, are respectively fastened to the frame 15 and the housing 11, thus enabling the wiring device 31 to be mounted to the housing 11.This eliminates the need for arrangement work for the electrical wires 41 inside the housing 11 and thus simplifies the manufacturing process of the control device 1. As described above, the wiring device 31, according to the embodiment, comprises a plate-shaped element 32 that is detachably mounted on the housing 11, and the electrical wires 41 are attached to the guide elements 33a and 33b, which are formed on the respective main surfaces 32a and 32b of the plate-shaped element 32. Since the plate-shaped element 32 is detachable, the electrical wire 41 can be arranged before the plate-shaped element 32 is mounted on the housing 11, and maintenance work on the electrical wire 41 can be carried out after the plate-shaped element 32 has been removed from the housing 11. This facilitates the arrangement, maintenance, and other operations involving the electrical wires 41.Since the electrical wires 41 are arranged along both sides of the plate-shaped element 32, i.e., the main surfaces 32a and 32b, the distance between adjacent electrical wires 41 can be increased compared to a case where the electrical wires 41 are arranged only on one side, thereby reducing the influence of electromagnetic noise emitted from the power line on the signal line. This configuration enables compliance with the electromagnetic compatibility (EMC) requirements placed on the control device 1 installed in railway vehicles. If the plate-shaped element 32 is made of metal, arranging the electrical wire 41 serving as a current conductor and the electrical wire 41 serving as a signal conductor on opposite sides of the plate-shaped element 32 can further reduce the influence of electromagnetic noise emitted from the current conductor to the signal conductor. The present disclosure is not limited to the embodiment described above. The structure and shape of the plate-shaped member 32 are not limited to the above example and can be any structure and shape that allows the electrical wires 41 to be arranged on both main surfaces 32a and 32b, and that allows the plate-shaped member 32 to be detachably mounted on the housing 11. By way of example, the main surfaces 32a and 32b of the plate-shaped member 32 can be curved surfaces. The mounting position of the plate-shaped link 32 is not limited to the example above and can be any position that allows the electrical wire 41 to be arranged on both main surfaces 32a and 32b. For example, the plate-shaped link 32 can 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 link 32 and the inner surface 11b is greater than or equal to a threshold value. For example, the distance between the main surface 32b of the plate-shaped link 32 and the inner surface 11b can be in a range of 60 mm to 90 mm inclusive. The position and shape of the through-hole 32c in the plate-shaped member 32 can be any position and shape that allows a subset of the electrical wires 41 to be routed from one of the principal surfaces 32a and 32b to the other principal surface 32a and 32b. For example, the plate-shaped member 32 can have a notch as a through-hole 32c. The design position and shape of the guide elements 33a and 33b can be any design position and shape that defines the placement position and / or the placement direction of the electrical wire 41. For example, the guide elements 33a can be formed at unequal intervals on the main surface 32a. Another example is that the guide element 33a, which is a projection, can be formed integrally with the plate-shaped element 32. Another example is that the guide element 33a can be a groove formed on the main surface 32a. The same applies to the guide element 33b. The shape, mounting position, and mounting method of the fastening elements 34 and 35 are not limited to the examples above and can be any shape, mounting position, and mounting method that allows the plate-shaped element 32 to be detachably attached to the housing 11. For example, the fastening element 34 can have the same shape as the fastening element 35 and be mounted directly to the housing 11. Alternatively, the fastening element 34 can be attached to the frame 15 and the plate-shaped element 32 by a fitting. Similarly, the fastening element 35 can be attached to the housing 11 and the plate-shaped element 32 by a fitting. Finally, the fastening element 35 can be attached to a different frame provided inside the housing 11. The fastening elements 34 and 35 can be permanently attached to the plate-shaped element 32 and detachably mounted to the frame 15 and the housing 11. For example, the fastening elements 34 and 35 can be formed integrally with the plate-shaped element 32 or attached to the plate-shaped element 32 by gluing, welding, or other assembly methods. Alternatively, the fastening elements 34 and 35 can be permanently attached to the frame 15 and the housing 11, respectively, and detachably mounted to the plate-shaped element 32. For example, the fastening elements 34 and 35 can each be attached to the frame 15 and the housing 11 by gluing, welding, or other assembly methods. As illustrated in Fig. 5, a locking element 17, having a shape capable of locking the plate-shaped element 32, can be provided inside the housing 11. In the example of Fig. 5, the control device 1 comprises a pair of locking elements 17 attached to the inner surface 11c of the housing 11. One end of each locking element 17 is attached to the inner surface 11c, and the other end of each locking element 17 is capable of locking the plate-shaped element 32. By providing the pair of locking elements 17, the fastening elements 34 and 35, mounted on the plate-shaped element 32, can be mounted on the housing 11 and on the frame 15 in a state in which the plate-shaped element 32 is locked to the pair of locking elements 17. This facilitates the task of attaching the plate-shaped link 32 to the housing 11. As another example, a frame with a main surface parallel to the XZ plane can be provided inside the housing 11, and a locking element, which is a plate-shaped element extending horizontally from the frame, can be formed. The foregoing describes some exemplary embodiments for illustrative purposes. Although the preceding discussion has presented specific embodiments, those skilled in the art will recognize that changes can be made with respect to a shape and a detail without departing from the broader spirit and scope of the invention. Accordingly, the description and the drawings are to be regarded as illustrative and not as restrictive. This detailed description is therefore not to be understood in a limiting sense, and the scope of the invention is defined only by the appended claims, together with the full scope of the equivalents to which such claims refer.
