DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. For the sake of convenience, components having the same reference numerals as components already described in the description of the embodiments will not be described. Furthermore, for the sake of convenience, the dimensions of each component shown in the drawings may differ from the actual dimensions of each component. In the following description, front, back, left, right, top, and bottom are defined as directions viewed from the side of the device on which the DIN rail is installed.

[0011] FIG. 1 is a schematic rear view of a device 1 according to an embodiment of the present invention. The device 1 includes a first device 100, a second device 200, a DIN rail R, and a device mounting part 10. The left side of FIG. 1 shows the first device 100 and the second device 200 in a state before they are attached to the DIN rail R. The right side of FIG. 1 shows the first device 100 and the second device 200 attached to the DIN rail R and fixed with the device mounting part 10. Note that the example in FIG. 1 shows a structure in which the first device 100 and the second device 200 can be attached, but three or more devices may be attached.

[0012] The first device 100 includes a casing having a generally rectangular parallelepiped shape with a left side L, a right side R, and a back side B that is attached to a DIN rail R. The casing contains electronic components such as a power converter and a control circuit.

[0013] The DIN rail R is a strip-shaped component that extends vertically and horizontally. The illustrated DIN rail R extends elongatedly in the horizontal direction. For this reason, in the following explanation, the horizontal direction will be referred to as the longitudinal direction of the DIN rail R, and the vertical direction will be referred to as the lateral direction of the DIN rail R.

[0014] An attachment mechanism 110 for attaching a DIN rail R is provided on the back surface B of the casing. The attachment mechanism 110 is composed of a rail groove portion 111, a locking portion 112, and a guide portion 113. The DIN rail R has a substantially rectangular shape. When actually installing the device 1 in a factory or the like, the DIN rail R is fixed in place in advance, and the first device 100 and the second device 200 are respectively fixed to the DIN rail R using the device attachment parts 10.

[0015] The rail groove portion 111 has a shape that extends in the left-right direction and is configured to fit over the DIN rail R. The locking portion 112 has an eave shape that protrudes downward from the upper end of the rail groove portion 111 and is configured to lock over the upper end of the DIN rail R.

[0016] The guide portion 113 is configured to slide the device attachment part 10 in the up and down direction.

[0017] The procedure for mounting the first device 100 and the second device 200 on the DIN rail R will be described. As shown on the right side of FIG. 1 , the rail groove portion 111 of the first device 100 is fitted from above onto the fixed DIN rail R, thereby engaging the locking portion 112 with the upper end of the DIN rail R. Furthermore, with the rail groove portion 111 of the first device 100 fitted onto the DIN rail R, the device mounting part 10 is slid upward via the guide portion 113 to lock onto the DIN rail R. Similarly, with the second device 200, the rail groove portion 111 of the second device 200 is fitted onto the DIN rail R so that the first device 100 and the second device 200 are adjacent to each other, and the DIN rail R is locked with the device mounting part 10. As a result, the first device 100 and the second device 200 are fixed onto the DIN rail R. First Embodiment

[0018] Hereinafter, a procedure for assembling the second device 200 to the first device 100 using the device attachment part 10 according to the first embodiment of the present disclosure will be described with reference to FIGS.

[0019] FIG. 2 is a perspective view of a device mounting part 10 according to a first embodiment of the present disclosure. As shown in FIG. 2, the device mounting part 10 has a mounting portion 11 and an extension portion 12. The mounting portion 11 is a portion for mounting a device to a DIN rail R, and is locked to the DIN rail R by sliding it upward via a guide portion 113. The extension portion 12 has a shape that extends in a direction intersecting the longitudinal direction of the DIN rail R, i.e., in a direction intersecting the guide portion 113. Specifically, the extension portion 12 protrudes forward from the plate-shaped mounting portion 11 that extends in the up-down and left-right directions. The extension portion 12 has a lower end plate portion 13, an upper end plate portion 14, and a relay plate portion 15 that connects the lower end plate portion 13 and the upper end plate portion 14.

[0020] The lower end plate 13 is a plate-like member extending in a direction intersecting the guide portion 113 and has an equipment fixing portion 12a at its rear end and an equipment fixing portion 12b at its front end. The upper end plate 14 is a plate-like member extending parallel to the longitudinal direction of the lower end plate 13 and has an equipment fixing portion 12c at its rear end and an equipment fixing portion 12d at its front end. In other words, the equipment fixing portions 12a to 12d are provided on a second plane intersecting a first plane including the DIN rail R. Furthermore, the equipment fixing portions 12a to 12d each have a shape that protrudes toward the left and bends upward, and may be engaging portions having the same structure and dimensions. The relay plate 15 is a plate-like member extending in the vertical direction and connects the center of the lower end plate 13 to the center of the upper end plate 14. Here, it is desirable that the equipment fixing portions 12b to 12d be located at positions away from the mounting portion 11. Furthermore, the mounting portion 11, the extension portion 12, and the device fixing portions 12a to 12d may be integrally molded to reduce the number of parts.

[0021] Hereinafter, a detailed structure of the device according to the first embodiment of the present disclosure will be described with reference to Figures 3 and 4. Figure 3 is a perspective view of the left side surface L of the first device 100. Figure 4 is a perspective view of the right side surface R of the second device 200.

[0022] 3, the left side surface L of the first device 100 is provided with four through holes 114a to 114d and a locking protrusion 115. The through holes 114a to 114d are shaped so that the device fixing portions 12a to 12d of the device mounting part 10 can be inserted therethrough. The locking protrusion 115 has a substantially rectangular parallelepiped shape and has a square cylindrical shape that protrudes outward from the left side surface L.

[0023] As shown in Fig. 4, the right side surface R of the second device 200 is provided with four through holes 116a to 116d and a locking hole 117. The through holes 116a to 116d are shaped so that the device fixing portions 12a to 12d of the device mounting part 10 can be inserted therethrough. The locking hole 117 is an opening having a substantially rectangular parallelepiped shape. Note that the locking holes 117 may be replaced by locking recesses.

[0024] The right side surface R of the first device 100 may be provided with four through holes 116a to 116d and a locking hole 117, similar to the right side surface R of the second device 200. Furthermore, the left side surface L of the second device 200 may be provided with four through holes 114a to 114d and a locking protrusion 115, similar to the left side surface L of the first device 100.

[0025] Hereinafter, a detailed structure of the device according to the first embodiment of the present disclosure will be described with reference to Fig. 5. Fig. 5 is an internal front view of the device 1 according to the first embodiment of the present disclosure as viewed from the rear surface B side.

[0026] In the procedure for assembling the second device 200 to the first device 100, first, as described above, the rail groove portion 111 of the first device 100 and the rail groove portion 111 of the second device 200 are fitted into the DIN rail R. At this time, as shown in FIG. 5 , the left side surface L of the first device 100 and the right side surface R of the second device 200 face each other, and the locking protrusion 115 on the left side surface L of the first device 100 enters and is locked into the locking hole 117 on the right side surface R of the second device 200. In addition, the extension portion 12 of the device mounting part 10 attached to the first device 100 is arranged in the internal space of the first device 100 so as to extend along the left side surface L, and the device fixing portions 12a to 12d enter into the through holes 114a to 114d on the left side surface L of the first device 100 and the through holes 116a to 116d on the right side surface R of the second device 200, respectively.

[0027] The through-holes 114a to 114d on the left side surface L of the first device 100 and the through-holes 116a to 116d on the right side surface R of the second device 200 are arranged at corresponding positions. Therefore, when the first device 100 and the second device 200 are adjacent to each other, the through-holes 114a to 114d on the left side surface L of the first device 100 and the through-holes 116a to 116d on the right side surface R of the second device 200 face each other.

[0028] Next, the device mounting component 10 is slid upward along the guide portion 113 to lock the DIN rail R. At this time, as shown in FIG. 5, the device fixing portions 12a to 12d are also slid upward. Because the device fixing portions 12a to 12d are bent upward, they face and engage with the upper portions of the through-holes 114a to 114d on the left side surface L of the first device 100 and the upper portions of the through-holes 116a to 116d on the right side surface R of the second device 200. In other words, the portions above the through-holes 114a to 114d and the portions above the through-holes 116a to 116d become engaged portions. As a result, the portions above the through-holes 114a to 114d and the portions above the through-holes 116a to 116d are fixed in the left-right direction, and the left side surface L of the first device 100 and the right side surface R of the second device 200 are fixed relatively to each other.

[0029] As described above, multiple devices can be firmly fixed because device fixing portions 12b to 12d are provided at positions spaced apart from mounting portion 11. Furthermore, because mounting portion 11, extension portion 12, and device fixing portions 12a to 12d are integrally molded, multiple devices can be firmly fixed with a small number of parts and a small number of assembly steps.

[0030] In this embodiment, the extension 12 is composed of three plates: the lower end plate 13, the upper end plate 14, and the relay plate 15. However, it may be composed of four or more plates, or may be composed of a single planar plate. In this embodiment, the extension 12 has four device fixing portions 12a-12d, and the device has four through holes 114a-114d on the left side L and four through holes 116a-116d on the right side R. However, the number of device fixing portions, through holes on the left side L, and through holes on the right side R may each be three or less, or five or more. In this embodiment, the device mounting component 10 is configured to slide upward along the guide portion 113 to lock the DIN rail R. However, it may also be configured to slide downward along the guide portion 113 to lock the DIN rail R.

[0031] Second Embodiment 6 to 9, a procedure for assembling the second device 200 to the first device 100 using the device attachment part 10′ according to the second embodiment of the present disclosure will be described. Note that in the second embodiment, only the differences from the first embodiment will be described, and descriptions of the same parts will be omitted.

[0032] Fig. 6 is a perspective view of a device mounting part 10' according to a second embodiment of the present disclosure. Unlike the device mounting part 10 according to the first embodiment shown in Fig. 2, the lower end plate 13 of the device mounting part 10' has an engaged part 12a' at the rear end and an engaged part 12b' at the front end, and the upper end plate 14 has an engaged part 12c' at the rear end and an engaged part 12d' at the front end. The engaged parts 12a' to 12d' may have the same structure and dimensions as one another. Here, the engaged parts 12a' to 12d' are: It is desirable that they are disposed at a position away from the mounting portion 11. Furthermore, the mounting portion 11, the extension portion 12, and the engaged portions 12a' to 12d' may be integrally molded to reduce the number of parts.

[0033] Hereinafter, a detailed structure of the device according to the second embodiment of the present disclosure will be described with reference to Figures 7 and 8. Figure 7 is a perspective view of the left side L of the device according to the second embodiment of the present disclosure. Figure 8 is a perspective view of the right side R of the device according to the second embodiment of the present disclosure. Since the first device 100 and the second device 200 have the same structure and dimensions, the detailed structure of the first device 100 will be described as a representative.

[0034] 7, four locking pieces 114a' to 114d' and a locking protrusion 115 are provided on the left side surface L of the first device 100. Each of the locking pieces 114a' to 114d' protrudes outward from the left side surface L and has a shape that is bent downward.

[0035] 8, four through holes 116a to 116d and a locking hole 117 are provided on the right side surface R of the first device 100. The through holes 116a to 116d are shaped so that the four locking pieces 114a' to 114d' on the left side surface L of the first device 100 can be inserted therethrough, respectively.

[0036] Hereinafter, a detailed structure of the device according to the second embodiment of the present disclosure will be described with reference to Fig. 9. Fig. 9 is an internal front view of the device 1 according to the second embodiment of the present disclosure as viewed from the rear surface B side.

[0037] In the procedure for assembling the second device 200 to the first device 100, first, as described above, the rail groove portion 111 of the first device 100 and the rail groove portion 111 of the second device 200 are fitted into the DIN rail R. At this time, as shown in FIG. 9 , the left side surface L of the first device 100 and the right side surface R of the second device 200 face each other, and the locking protrusion 115 on the left side surface L of the first device 100 enters and is locked into the locking hole 117 on the right side surface R of the second device 200. In addition, the four locking pieces 114a' to 114d' on the left side surface L of the first device 100 enter into the through holes 116a to 116d on the right side surface R of the second device 200, respectively. In addition, the extension portion 12 of the device mounting part 10' attached to the second device 200 is arranged in the internal space of the second device 200 so as to be along the right side surface R.

[0038] The locking pieces 114a' to 114d' on the left side surface L of the first device 100 and the through holes 116a to 116d on the right side surface R of the second device 200 are arranged at corresponding positions. Therefore, when the first device 100 and the second device 200 are adjacent to each other, the locking pieces 114a' to 114d' on the left side surface L of the first device 100 and the through holes 116a to 116d on the right side surface R of the second device 200 face each other.

[0039] Next, the device mounting part 10' is slid upward along the guide portion 113 to lock the DIN rail R. At this time, as shown in FIG. 9, the engaged portions 12a' to 12d' are also slid upward. Because the locking pieces 114a' to 114d' are bent downward, they face and engage with the engaged portions 12a' to 12d'. As a result, the engaged portions 12a' to 12d' are fixed in the left-right direction, and the left side surface L of the first device 100 and the right side surface R of the second device 200 are fixed relatively to each other.

[0040] As described above, multiple devices can be firmly fixed because engaged portions 12a' to 12d' are provided at positions spaced apart from mounting portion 11. Furthermore, because mounting portion 11 and extension portion 12 are integrally molded, multiple devices can be firmly fixed with a small number of parts and a small number of assembly steps.

[0041] In this embodiment, the extension 12 has four engaged portions 12a' to 12d', and the device has four locking pieces 114a' to 114d' on the left side surface L and four through holes 116a to 116d on the right side surface R. The numbers of the device fixing portion, the locking pieces on the left side surface L, and the through holes on the right side surface R are as follows: The number of each may be three or less, or may be five or more. The device mounting part 10' is configured to slide upward along the guide part 113 to lock the DIN rail R, but it may also be configured to slide downward along the guide part 113 to lock the DIN rail R.

[0042] However, if the device mounting part 10 is not provided with any guide mechanism, the device mounting part 10 will move freely inside the first device 100. In particular, the device mounting part 10 has a plate-shaped connecting plate part 12 (described as the extension part 12 in FIG. 2 ), and when the device mounting part 10 moves in the left-right direction, this connecting plate part 12 may interfere with electronic components inside the first device 100. Therefore, in order to restrict the left-right movement of the device attachment part 10, it is conceivable to provide a guide part for guiding the device attachment part 10 inside the first device 100. However, if such a guide part is provided inside the first device 100, the first device 100 will become larger in size. Therefore, the present disclosure uses a structure described in detail below to prevent the device attachment part 10 from moving in an unintended direction without increasing the size of the first device 100.

[0043] Fig. 10 is a perspective view of the equipment mounting part 10. Note that the equipment mounting part 10 shown in Fig. 10 is the same as the equipment mounting part 10 shown in Fig. 2, but in the following description, the names of some parts will be changed for ease of explanation. As shown in Fig. 10, the equipment mounting part 10 of this embodiment has a rail connecting part 11 (described as the mounting part 11 in Fig. 2), four claw parts 20, and a plate-shaped connecting plate part 12.

[0044] The rail connecting portion 11 is a portion that engages with the DIN rail R as the equipment mounting part 10 moves in the vertical direction (the short side direction of the strip-shaped DIN rail R), and can switch between a connected state and a non-connected state with the DIN rail R. In the illustrated example, the rail connecting portion 11 is provided at the rear lower part of the equipment mounting part 10, and is a substantially plate-shaped portion that extends in the left-right and up-down directions.

[0045] 11 is a diagram illustrating the connection state by the rail connecting portion 11. FIG. 11 is a diagram illustrating the rail connecting portion 11 and the DIN rail R in a cross section extending in the front-rear and up-down directions. As shown in FIG. 11, the first device 100 is attached to the DIN rail R from above, and the DIN rail R is inserted into the rail groove portion 111. In this state, the upper part of the DIN rail R fits into the canopy-shaped locking portion 112 of the first device 100.

[0046] When the equipment mounting part 10 is moved upward in this state, the rail connecting part 11 is positioned at the rear surface of the lower part of the DIN rail R, and the DIN rail R is sandwiched between the rail connecting part 11 and the rear surface of the first equipment 100. This places the first equipment 100 in a connected state in which movement in the front-to-rear direction relative to the DIN rail R is prevented. Note that when the equipment mounting part 10 is moved downward from this connected state, the first equipment 100 enters an unconnected state in which movement in the front-to-rear direction relative to the DIN rail R is possible. Note that in Figure 11, the equipment mounting part 10 in the connected state is drawn with imaginary lines.

[0047] 10, the connecting plate 12 of the equipment mounting part 10 is a plate-shaped portion extending in the up-down and front-rear directions. The connecting plate 12 has an intermediate plate 15 extending in the up-down direction, an upper end plate 14 protruding forward and rearward from the upper end of the connecting plate 12, and a lower end plate 13 protruding forward and rearward from the lower end of the connecting plate 12.

[0048] The four claws 20 are provided on the left surface of the connecting plate 12. The first claw 21 is provided at the rear end of the lower end plate 13. The second claw 22 is provided at the front end of the lower end plate 13. The third claw 23 is provided at the rear end of the upper end plate 14. The fourth claw 24 is provided at the front end of the upper end plate 14.

[0049] Fig. 12 is a cross-sectional view showing how the first device 100 and the second device 200 are connected by the device mounting part 10. Fig. 12 is a cross-section extending in the up-down and left-right directions through the first claw portion 21 and the third claw portion 23, showing the device mounting part 10, the first device 100, and the second device 200.

[0050] The claw portions 20 of the device mounting part 10 extend from the inside of the first device 100 to the inside of the second device 200 so as to pass through the through holes of the casing 120 of the first device 100 and the through holes of the casing 220 of the second device 200. The connecting plate portion 12 is a plate-shaped portion provided inside the first device 100 and connecting the plurality of claw portions 20 together.

[0051] 12, the first claw portion 21 penetrates a first through-hole 114a provided in the left side surface portion 121 of the casing 120 of the first device 100 and a fifth through-hole 116a provided in the right side surface portion 221 of the casing 220 of the second device 200. The tip portion (left end portion) of the first claw portion 21 penetrates into the interior of the second device 200. The second claw portion 22 penetrates through a second through-hole 114b provided in the left side surface portion 121 of the casing 120 of the first device 100 and a sixth through-hole 116b provided in the right side surface portion 221 of the casing 220 of the second device 200. The tip portion (left end portion) of the second claw portion 22 enters the interior of the second device 200. The third claw portion 23 penetrates a third through-hole 114c provided in the left side surface portion 121 of the casing 120 of the first device 100 and a seventh through-hole 116c provided in the right side surface portion 221 of the casing 220 of the second device 200. The tip portion (left end portion) of the third claw portion 23 enters the interior of the second device 200. The fourth claw portion 24 penetrates a fourth through-hole 114d provided in the left side surface portion 121 of the casing 120 of the first device 100 and an eighth through-hole 116d provided in the right side surface portion 221 of the casing 220 of the second device 200. The tip portion (left end portion) of the fourth claw portion 24 enters the interior of the second device 200. In the following description, the first claw portion 21 to the fourth claw portion 24 may be collectively referred to simply as the claw portions 20.

[0052] 10, each of the claw portions 20 has a shaft portion 31 protruding leftward from the connecting plate portion 12, an inter-device connection claw portion 32, and a guide claw portion 33. The inter-device connection claw portion 32 and the guide claw portion 33 are each provided at the tip of the shaft portion 31 (the left end portion in the illustrated example).

[0053] The shaft portion 31 has a smaller diameter than the first through hole 114a to the fourth through hole 114d provided in the left side surface portion 121 of the first device 100. The shaft portion 31 has a smaller diameter than the fifth through hole 116a to the eighth through hole 116d provided in the right side surface portion 221 of the second device 200. The shaft portion 31 is movable in the up and down direction inside the first through hole 114a to the fourth through hole 114d and the fifth through hole 116a to the eighth through hole 116d.

[0054] The inter-device connection claw portion 32 is engaged with the flat portion (right side surface portion 221) of the casing 220 of the second device 200 as the device mounting part 10 moves in the short direction, and is a portion that can switch between a connected state and a non-connected state of the first device 100 with the second device 200.

[0055] 12, the inter-apparatus connection claw 32 is a portion bent upward from the tip of the shaft 31. Focusing on the first claw 21, when the shaft 31 abuts against the upper surfaces forming the first through hole 114a and the fifth through hole 116a, the right surface of the inter-apparatus connection claw 32 faces the left surface of the right side surface 221 of the second device 200. In this state, the left side surface 121 of the first device 100 and the right side surface 221 of the second device 200 are sandwiched between the right surface of the inter-apparatus connection claw 32 and the connecting plate 12, and the first device 100 and the second device 200 are prevented from moving in the left-right direction.

[0056] Fig. 13 is a view of the left side surface part 121 of the first device 100 as seen from the left. In Fig. 13, the fifth through hole 116a to the eighth through hole 116d of the second device 200 connected to the first device 100 are shown by virtual lines. As shown in FIG. 13, the guide claw portion 33 is a portion that is always engaged with the flat portion (right side portion 121) of the casing 120 of the first equipment 100, regardless of the movement of the equipment mounting part 10 in the short direction (up and down direction) of the DIN rail R, and guides the movement of the equipment mounting part 10 in the short direction (left and right direction) of the DIN rail R.

[0057] In the illustrated example, the guide claw portion 33 of the first claw portion 21 is at a position that protrudes leftward from the right side portion 221 of the casing 120 of the first device 100, and protrudes rearward from the rear surface 114a1 that forms the first through hole 114a. The guide claw portion 33 of the second claw portion 22 is located at a position protruding leftward from the right side surface portion 221 of the casing 120 of the first device 100, and protrudes forward from the front surface 114b1 forming the second through-hole 114b. The guide claw portion 33 of the third claw portion 23 is located at a position protruding leftward from the right side surface portion 221 of the casing 120 of the first device 100, and protrudes rearward from the rear surface 114c1 forming the third through-hole 114c. The guide claw portion 33 of the fourth claw portion 24 is located at a position protruding leftward from the right side surface portion 221 of the casing 120 of the first device 100, and protrudes forward from the front surface 114d1 forming the fourth through-hole 114d.

[0058] 13, even if the inter-device connecting claw portion 32 moves up and down, the guide claw portion 33 is always kept engaged with the right side surface portion 221 of the casing 120 of the first device 100, guiding the up and down movement of the device mounting part 10. Since the guide claw portion 33, together with the connecting plate portion 12, is always kept in a state of sandwiching the right side surface portion 221 of the casing 120 of the first device 100, the device mounting part 10 does not rattle in the left and right directions relative to the first device 100. In this way, the guide claw portion 33 is provided on the claw portion 20 provided for connecting the devices 100, 200 of the device attachment part 10, so there is no need to provide a separate guide portion inside the first device 100, and an increase in size of the first device 100 is suppressed. In this way, the device attachment part 10 of the present disclosure prevents movement in an unintended direction without causing an increase in size of the first device 100.

[0059] The front-to-rear dimensions of the fifth through hole 116a to the eighth through hole 116d provided in the right side surface portion 221 of the casing 220 of the second device 200 are made larger than the front-to-rear dimension of the claw portion 20 to avoid interference with the guide claw portion 33.
