Summary of the Invention

Problems to be Solved by the Invention

[0005] The problem to be solved by the present invention is to provide a substrate device capable of preventing incorrect insertion.

Means for Solving the Problems

[0006] The substrate device of the embodiment includes a control board, a board-side connector, a transmission module board, and a mounting kit. The board-side connector inserts and removes a plurality of pins parallel to the substrate surface of the control board. The transmission module board has a transmission-side connector that inserts and removes from the board-side connector. The transmission module board is mounted on the control board in a manner parallel to and spaced apart from the control board. The mounting kit is provided with a pair of mounting kits for attaching the transmission module board to the control board at positions on both sides of the transmission module board that intersect with the mounting direction parallel to the pins relative to the control board. Each of the mounting kits comprises a B part and a T part. The B part is attached to the control board. The T part sandwiches the transmission module board between itself and the B part. The aforementioned part B has a mounting surface and a mounting position clamping regulating portion. The mounting surface is used to mount the transmission module board in a position parallel to and spaced apart from the control board. The mounting position clamping regulating portion contacts the two lateral ends of the transmission module board. The T-part has a mounting contact surface and a mounting position direction restricting portion. The mounting contact surface contacts the B-part outward in a direction intersecting the mounting direction from the two lateral end positions of the transmission module board. The mounting position direction restricting portion is formed on the mounting contact surface. The mounting position direction restricting portion restricts the mounting position of the T-part relative to the B-part. The mounting position direction restricting portion restricts the combined position of the T-part to be mounted relative to the B-part at both outer positions of the transmission module board intersecting the mounting direction.

[Modes for carrying out the invention]

[0008] The substrate device of the embodiment will be described below with reference to the drawings. Figure 1 is a top view showing the substrate device in this embodiment. Figure 2 is a front view showing the substrate device in this embodiment. Figure 3 is a side view showing the substrate device in this embodiment. In the figures, reference numeral 10 denotes the substrate device. Hereinafter, the axial directions of the X-axis, Y-axis, and Z-axis that are orthogonal to each other in the three-dimensional space are directions parallel to each axis. For example, as shown in FIG. 1, the X-axis direction is parallel to the left-right direction orthogonal to the mounting direction of the transmission module substrate 20 described later. The Y-axis direction is parallel to the front-rear direction which is the mounting direction of the transmission module substrate 20. The Z-axis direction is parallel to the up-down direction of the transmission module substrate 20.

[0009] The substrate device 10 according to the present embodiment is used, for example, in a drive device that can be connected to a motor control or a control device of a programmable logic circuit. The substrate device 10 is expandable. The substrate device 10 can be used as a drive for plant control. As shown in FIGS. 1 to 3, the substrate device 10 includes a control substrate 11, a transmission module substrate 20, and a mounting kit 30.

[0010] The control substrate 11 is attached with the mounting kit 30. The transmission module substrate 20 is attached to the mounting kit 30. The control substrate 11 has a contour shape that is larger than the transmission module substrate 20 in a plan view in the Z-axis direction. The control substrate 11 has a substantially rectangular contour shape when viewed in the Z-axis direction. The contour shape of the control substrate 11 is not limited to this. The control substrate 11 has a substrate surface 11a extending along the X-axis direction and the Y-axis direction. Among the contour shapes of the control substrate 11 viewed in the Z-axis direction, the ends extend along the X-axis direction and the Y-axis direction. In addition to the substrate-side connector 12, electrical components are attached to the control substrate 11. These electrical components are not shown.

[0011] The control substrate 11 is electrically connected to the transmission module substrate 20. The control substrate 11 has a substrate-side connector 12. The substrate-side connector 12 is electrically connected to the transmission-side connector 22. The transmission-side connector 22 is disposed on the transmission module substrate 20. The control substrate 11 and the transmission module substrate 20 are attached parallel to each other. The mounting kit 30 and the transmission module substrate 20 are attached to the substrate surface 11a of the control substrate 11. The substrate surface 11a is the upper surface of the control substrate 11 when viewed in the Z-axis direction.

[0012] The board-side connector 12 is attached to the control board 11. The board-side connector 12 is attached to the board surface 11a. The board-side connector 12 is electrically connected to the control board 11 via wiring or the like. The wiring or the like connecting the board-side connector 12 and the control board 11 is not shown in the figure. The board-side connector 12 is arranged adjacent to the transmission module substrate 20 in a plan view in the Z-axis direction. The board-side connector 12 extends in the X-axis direction. The board-side connector 12 has the Y-axis direction as the insertion / removal direction as described later. The board-side connector 12 has a plurality of pins 12a (see FIG. 4).

[0013] In the X-axis direction, a straight line along the Y-axis direction passing through the center of the board-side connector 12 is defined as the center position (center line) C. The center line C extends along the mounting direction, which is the relative movement direction between the transmission module substrate 20 and the control substrate 11 when attaching the transmission module substrate 20 to the control substrate 11. The center line C is along the insertion / removal direction between the board-side connector 12 and the transmission-side connector 22. The center line C may be treated as the YZ plane in the following description.

[0014] A plurality of pins 12a are arranged in the X direction. All of the plurality of pins 12a protrude in the Y-axis direction from the connector body 12b. The connector body 12b has a rectangular contour when viewed from above in the Y-axis direction. All of the plurality of pins 12a are parallel to each other. All of the plurality of pins 12a are parallel to the board surface 11a. All of the plurality of pins 12a are spaced apart from each other. All of the plurality of pins 12a have the same separation distance Te in the X-axis direction. All of the plurality of pins 12a extend in the Y-axis direction. All of the plurality of pins 12a extend in the through-ahead direction of the transmission module substrate 20. The direction in which the plurality of pins 12a extend defines the through-ahead direction of the transmission module substrate 20.

[0015] Multiple pins 12a all have the same Y-axis length. Multiple pins 12a are arranged such that their base ends are the same in the Y-axis direction along the X-axis. Multiple pins 12a are arranged such that their tip positions are the same in the Y-axis direction along the X-axis. The tips of multiple pins 12a are all located in a plane along the XZ plane.

[0016] The pins 12a are arranged in multiple rows in the Y direction. For example, the pins 12a are arranged in two rows in the Y direction. Multiple pins 12a are all positioned at the same base end position in the Y-axis direction. Multiple pins 12a are arranged in the Z-axis direction so that their base end positions are the same as in the Y-axis direction. Multiple pins 12a are arranged in the Z-axis direction so that their tip positions are the same as in the Y-axis direction. The arrangement of the pins 12a is not limited to these.

[0017] The control board 11 is provided with mounting holes 13a, 13b, and 13c. Mounting hole 13a is formed in a position symmetrical with respect to the center line C. Mounting hole 13b is formed in a position symmetrical with respect to the center line C (see Figure 5). Mounting hole 13c is formed in a position symmetrical with respect to the center line C. Mounting holes 13a, 13c, and 13b form a row along the Y-axis. The row of mounting holes 13a, 13c, and 13b is arranged on both sides with respect to the center line C.

[0018] The transmission module board 20 is mounted on the control board 11. The transmission module board 20 is mounted close to a corner of the control board 11. The transmission module board 20 is electrically connected to the control board 11. The transmission module board 20 has an external connection connector 21. The external connection connector 21 is connected to an external PLC (Programmable Logic Controller), etc. The transmission module board 20 has a transmission-side connector 22. The transmission-side connector 22 is connected to the board-side connector 12. In addition to the transmission-side connector 22 and the external connection connector 21, other electrical components are attached to the transmission module board 20. These electrical components are not shown in the illustration.

[0019] The transmission module substrate 20 has a substrate surface 20a that extends along the X-axis and Y-axis. The substrate surface 20a of the transmission module substrate 20 is mounted parallel to the substrate surface 11a of the control board 11. The transmission module substrate 20 and the control board 11 are spaced apart from each other in the Z-axis direction. The substrate surfaces 20a and 11a are parallel to each other. The substrate surfaces 20a and 11a are spaced apart from each other in the Z-axis direction. The substrate surface 20a is the upper surface of the transmission module substrate 20 when viewed in the Z-axis direction.

[0020] The transmission module substrate 20 has a smaller profile than the control substrate 11 when viewed in plan along the Z-axis. The transmission module substrate 20 has a substantially rectangular profile when viewed in plan along the Z-axis. The profile of the transmission module substrate 20 is symmetrical with respect to the center line C when mounted on the control substrate 11. The profile of the transmission module substrate 20 is not limited to this. The transmission module substrate 20 has a contour shape when viewed in the Z-axis direction, with its ends extending along the X-axis and Y-axis directions. The edges of the transmission module substrate 20's contour shape, when viewed in the Z-axis direction, along the X-axis and Y-axis directions, are mounted parallel to the edges of the control substrate 11's contour shape.

[0021] The transmission-side connector 22 and the external connection connector 21 are located at the ends of the transmission module board 20 in the Y direction.

[0022] The transmission-side connector 22 is positioned at the front end of the transmission module board 20 in the Y direction. The transmission-side connector 22 is positioned parallel to the front end extending in the X direction of the contour shape of the transmission module board 20 when viewed in the Z direction. The dimension of the transmission-side connector 22 along the X direction is approximately equal to the total length of the front end of the contour shape of the transmission module board 20 when viewed in the Z direction. The thickness dimension of the transmission-side connector 22 in the Z direction is greater than the thickness dimension of the transmission module board 20.

[0023] The transmission-side connector 22 is positioned closer to the control board 11 in the Z-axis direction than to the substrate surface 20a. The transmission-side connector 22 protrudes from the transmission module substrate 20 in the Z-axis direction, closer to the control board 11. The thickness dimension Tt22 of the transmission-side connector 22 in the Z-axis direction is greater than the thickness dimension Tt of the transmission module substrate 20 (see Figure 15). The transmission-side connector 22 protrudes from the back surface 20b in the direction from the substrate surface 20a toward the back surface 20b. The transmission-side connector 22 has an insertion / removal direction in the Y-axis direction relative to the board-side connector 12. The transmission-side connector 22 has an insertion / removal direction parallel to the board surface 11a relative to the board-side connector 12. The transmission-side connector 22 has an insertion / removal direction parallel to the board surface 20a relative to the board-side connector 12.

[0024] The external connection connector 21 is located at the rear end of the transmission module board 20 in the Y direction. The external connection connector 21 is positioned parallel to the rear end extending in the X direction of the contour shape of the transmission module board 20 when viewed in the Z direction. The dimension of the external connection connector 21 along the X direction is shorter than the total length of the rear end of the contour shape of the transmission module board 20 when viewed in the Z direction. The external connection connector 21 may have fixing parts 21a such as bolts for fixing an external connector. The insertion and removal direction of the external connection connector 21 to the external connector is in the Y direction.

[0025] The transmission-side connector 22 and the external connection connector 21 are parallel to each other. The external connection connector 21 is positioned at a distance from the control board 11 in the Z-axis direction from the substrate surface 20a. The external connection connector 21 protrudes from the transmission module substrate 20 so as to be at a distance from the control board 11 in the Z-axis direction. The insertion and removal direction of the external connection connector 21 is parallel to the substrate surface 20a. The insertion and removal direction of the external connection connector 21 is parallel to the substrate surface 20a. The insertion and removal direction of the external connection connector 21 is not limited to this.

[0026] The mounting kit 30 fixes the transmission module board 20 to the control board 11. The mounting kit 30 fixes both lateral ends of the transmission module board 20 in the X-axis direction. The mounting kit 30 makes contact with both lateral ends of the transmission module board 20 in the X-axis direction. A pair of mounting kits 30 are positioned corresponding to both lateral ends of the transmission module board 20 in the X-axis direction.

[0027] The pair of mounting kits 30 attach the transmission module board 20 to the control board 11. The pair of mounting kits 30 attach the transmission module board 20 to the control board 11 at both lateral ends of the transmission module board 20 in the X-axis direction. The pair of mounting kits 30 have a distance Tc in the Y-axis direction between their front ends and the substrate-side connector 12 (see Figure 4). The distance Tc is the distance between the front end of the mounting kit 30 and the tip of the pin 12a in the Y-axis direction.

[0028] The pair of mounting kits 30 are arranged symmetrically on both sides of the transmission module substrate 20 with respect to the center line C in the X-axis direction. The pair of mounting kits 30 are positioned along both ends of the transmission module substrate 20 in the X-axis direction. The pair of mounting kits 30 extend along the Y-axis direction. The pair of mounting kits 30 are spaced apart from each other in the X-axis direction. The distance between the pair of mounting kits 30 in the X-axis direction is slightly narrower than the X-direction dimension of the transmission module board 20.

[0029] The pair of mounting kits 30 are configured to be symmetrical with respect to the center line C. In the pair of mounting kits 30, the distances from the center line C of each component are equal in the Y-axis direction.

[0030] The mounting kit 30 on the right side of Figure 1 will be described below. Note that the mounting kit 30 on the left side of Figure 1 will be described separately, with the corresponding components being denoted by the same reference numerals.

[0031] The mounting kit 30 comprises part B 31 and part T 41. Part B 31 is attached to the control board 11. Part B 31 is attached to the board surface 11a. Part B 31 is in contact with the transmission module board 20 above in the Z-axis direction. Part B 31 is sandwiched between the transmission module board 20 and the control board 11. T-part 41 sandwiches the transmission module board 20 between itself and B-part 31. Both B-part 31 and T-part 41 extend along the Y-axis.

[0032] Figure 4 is a perspective view showing the control board 11 and part B 31 in this embodiment. The control board 11 contacts the back surface 32b of part B 31 in the Z-axis direction. The transmission module board 20 contacts the mounting surface (top surface) 32a of part B 31 in the Z-axis direction. Part B 31 is fixed to the control board 11 by bolts B. The bolts B are screwed into mounting holes 13c, which are through holes formed in the control board 11. Part B 31 has a mounting portion 32, an upright portion 33, and an overhanging portion 34.

[0033] The mounting portion 32 extends in the Y-axis direction. The upright portion 33 rises upward in the Z-axis direction from the front end of the mounting portion 32 in the Y-axis direction. The overhanging portion 34 extends from the upper end of the upright portion 33 in the Z-axis direction toward the center line C in the X-axis direction.

[0034] The mounting portion 32 has a rectangular cross-section in the ZX plane. The mounting portion 32 has a thickness dimension Tg in the Z-axis direction. The mounting portion 32 extends along the X-axis edge of the transmission module substrate 20. The mounting portion 32 contacts the back surface 20b of the transmission module substrate 20. The mounting portion 32 has a predetermined width dimension in the X-axis direction. The mounting portion 32 extends inward and outward in the X-axis direction of the contour of the transmission module substrate 20 when viewed in the Z-axis direction.

[0035] The mounting portion 32 has a mounting surface 32a and a back surface 32b. The mounting portion 32 has a through hole 36c for the bolt B. The through hole 36c for the bolt B penetrates from the mounting surface 32a to the back surface 32b in the Z-axis direction. The through hole 36c coincides with the fastening position 36c of the bolt B.

[0036] The mounting surface 32a contacts the back surface 20b of the transmission module substrate 20. The mounting surface 32a is formed on the upper surface of the mounting portion 32 in the Z-axis direction. The mounting surface 32a is formed in the region of the upper surface of the mounting portion 32 in the Z-axis direction that is close to the center line C. The back surface 32b contacts the substrate surface 11a of the control board 11. The back surface 32b is formed on the lower surface of the mounting portion 32 in the Z-axis direction. The control board 11 contacts the back surface 32b. The back surface 32b extends from the lower end of the mounting portion 32 to the lower end of the upright portion 33.

[0037] The mounting surface 32a is formed on the upper surface of the mounting portion 32 in the Z-axis direction. The mounting surface 32a forms a plane along the XY plane. The mounting surface 32a extends in the Y-axis direction. The mounting surface 32a has a predetermined width dimension in the X-axis direction. The mounting surface 32a extends inward and outward in the X-axis direction of the contour of the transmission module substrate 20 when viewed in the Z-axis direction. The mounting surface 32a is parallel to the substrate surface 11a. The mounting surface 32a is spaced a predetermined distance from the substrate surface 11a in the Z-axis direction. The mounting surface 32a is spaced a predetermined distance from the substrate surface 11a in the Z-axis direction.

[0038] The back surface 20b of the transmission module board 20 has its edges placed on the mounting surface 32a. The back surface 20b of the transmission module board 20 has its edges in contact with the mounting surface 32a. The mounting surface 32a has a mounting contact surface 32c that does not come into contact with the transmission module substrate 20, located outside the contour of the transmission module substrate 20 when viewed in the Z-axis direction.

[0039] The mounting contact surface 32c is formed on the upper surface of the mounting portion 32 in the Z-axis direction. The mounting contact surface 32c is parallel to the substrate surface 11a. The mounting contact surface 32c forms a plane along the XY plane. The mounting contact surface 32c is continuous with the mounting surface 32a. The mounting contact surface 32c lies on the same XY plane as the mounting surface 32a. The mounting contact surface 32c is flush with the mounting surface 32a. The mounting contact surface 32c is spaced a predetermined distance from the substrate surface 11a in the Z-axis direction. The boundary line G between the mounting contact surface 32c and the mounting surface 32a extends in the Y-axis direction. The mounting contact surface 32c is located further away from the center line C than the boundary line G. The mounting surface 32a is located closer to the center line C than the boundary line G. The boundary line G follows the contour of the transmission module board 20. The boundary line G is a straight line corresponding to the movement of the contour of the transmission module board 20. The boundary line G may not be a straight line depending on the contour of the transmission module board 20.

[0040] The mounting contact surface 32c has a pair of direction-restricting recesses 35a and 35b. The direction-restricting recesses 35a and 35b constitute a mounting position direction-restricting portion. Direction-restricting recesses 35a and 35b are positioned spaced apart from each other in the X-axis direction on the mounting contact surface 32c. Direction-restricting recesses 35a and 35b are located close to both ends of the mounting contact surface 32c in the X-axis direction. Both direction-restricting recesses 35a and 35b are recessed in the Z-axis direction from the mounting contact surface 32c.

[0041] The direction-restricting recesses 35a and 35b have different contour shapes when viewed in the Z-axis direction. For example, the contour shape of the direction-restricting recess 35a can be made shorter in the X-axis direction dimension than the contour shape of the direction-restricting recess 35b. Alternatively, the contour shape of the direction-restricting recess 35a can be made longer in the Y-axis direction dimension than the contour shape of the direction-restricting recess 35b. Such contour shapes are just examples; it is sufficient that the contour shapes of the direction-restricting recess 35a and 35b are different, and that there is a difference in relative shape such that the T-part 41 cannot be attached and fixed to the B-part 31 simply by placing it in the wrong orientation.

[0042] The direction-restricting recesses 35a and 35b correspond to the direction-restricting protrusions 42a and 42b formed on the T-part 41, which will be described later. The direction-restricting protrusions 42a and 42b formed on the T-part 41, which will be described later, can be fitted into the direction-restricting recesses 35a and 35b. When the direction-restricting recesses 35a and 35b are fitted into the T-part 41, which will be described later, in the correct orientation, the direction-restricting protrusions 42a and 42b can be housed in them. The direction-restricting protrusions 42a and 42b constitute the mounting position direction-restricting section.

[0043] Here, the fact that the direction-restricting projection 42a can be housed in the direction-restricting recess 35a, and that the direction-restricting projection 42b can be housed in the direction-restricting recess 35b, corresponds to the state in which the mounting contact surface 41b and the mounting contact surface 32c, which are the lower surfaces of the T-part 41 described later, are in parallel contact. The direction-restricting recess 35a and the direction-restricting recess 35b have such fitting conditions.

[0044] Furthermore, the directional restricting recess 35a and the directional restricting recess 35b may have different separation distances from each other in the Y-axis direction with respect to the fastening position 36c of the bolt B located near the center of the mounting contact surface 32c. The direction-restricting recess 35a, the fastening position 36c of bolt B, and the direction-restricting recess 35b are positioned in this order in the Y-axis direction. In the Y-axis direction, the distance between bolt B and the direction-restricting recess 35a can be different from the distance between bolt B and the direction-restricting recess 35b.

[0045] Furthermore, the directional restricting recesses 35a and 35b may be arranged differently from each other in the X-axis direction. Arrangement differently from each other in the X-axis direction means that the distance between the center line C and the directional restricting recess 35a is different from the distance between the center line C and the directional restricting recess 35b in the X-axis direction.

[0046] The direction-restricting recesses 35a and 35b can have different contour shapes when viewed in the Z-axis direction. In Figure 4, both the direction-restricting recesses 35a and 35b are shown as rectangular contours, but the shape is not limited to this. For example, the direction-restricting recess 35a can have a rectangular contour shape, while the direction-restricting recess 35b can have a triangular contour shape that does not fit within this rectangle.

[0047] The depth dimensions in the Z-axis direction of the directional restricting recess 35a and the directional restricting recess 35b can be different from each other. The length dimensions in the Z-axis direction of the directional restricting protrusion 42a and the directional restricting protrusion 42b can be different from each other. For example, the depth dimension of the directional restricting recess 35a can be smaller than the depth dimension of the directional restricting recess 35b. For example, the length dimension of the directional restricting protrusion 42a can be smaller than the length dimension of the directional restricting protrusion 42b.

[0048] In this case, if the T part 41 is placed in the wrong orientation, the directional restricting protrusion 42a, which has a smaller Z-axis dimension, is inserted into the directional restricting recess 35b, which has a larger Z-axis dimension. The directional restricting protrusion 42b, which has a larger Z-axis dimension, is inserted into the directional restricting recess 35a, which has a smaller Z-axis dimension. The directional restricting protrusion 42b abuts against the bottom of the directional restricting recess 35a. The mounting contact surface 41b and the mounting contact surface 32c are tilted at an angle, and there are areas where the mounting contact surface 41b and the mounting contact surface 32c do not come into contact with each other. The mounting contact surface 41b and the mounting contact surface 32c do not come into full contact with each other. This makes it possible to determine if the T part 41 is placed in the wrong orientation. Note that the depth dimension in the Z-axis direction of the orientation restricting recess 35a and the orientation restricting recess 35b is not limited to this condition.

[0049] The mounting kit 30 is configured to be symmetrical with respect to the center line C, except for the direction-restricting recesses 35a and 35b. In other words, the T part 41 that is attached to the B part 31 on the right side in Figure 1 cannot be attached to the B part 31 on the left side in Figure 1.

[0050] To achieve this configuration, in Figure 4, the directional restricting recesses 35a and 35b shown above the center line C have different contour shapes and / or arrangements compared to the directional restricting recesses 35a1 and 35b1 shown below the center line C. This difference in contour shape and / or arrangement can be based on the conditions for fitting the directional restricting recesses 35a and 35b described above.

[0051] On the back surface 32b, direction-regulating protrusions 36a and 36b are formed, which are inserted into the mounting holes 13a and 13b of the control board 11, which will be described later. The direction-regulating protrusions 36a and the mounting hole 13a have corresponding shapes to each other. The direction-regulating protrusions 36b and the mounting hole 13b have corresponding shapes to each other. The direction-regulating protrusion 36a is inserted into the mounting hole 13a. The direction-regulating protrusion 36b is inserted into the mounting hole 13b.

[0052] The direction-regulating projection 36a is located on the back surface 32b near the end in the Y-axis direction. The direction-regulating projection 36a may be located in the Y-axis direction, overlapping with the upright portion 33 when viewed in the Z-axis direction. The direction-regulating projection 36a may be located in the Y-axis direction, not overlapping with the upright portion 33 when viewed in the Z-axis direction. When the direction-regulating projection 36a is inserted into the mounting hole 13a, its tip may slightly protrude from the back surface 11b of the control board 11. When the direction-regulating projection 36a is inserted into the mounting hole 13a, its tip may be slightly recessed from the back surface 11b of the control board 11. When the direction-regulating projection 36a is inserted into the mounting hole 13a, its tip may be flush with the back surface 11b of the control board 11.

[0053] The direction-regulating projection 36b is located near the end in the Y-axis direction on the back surface 32b. The direction-regulating projections 36a and 36b are located near both ends in the Y-axis direction on the back surface 32b, respectively. When the direction-regulating projection 36b is inserted into the mounting hole 13b, its tip may slightly protrude from the back surface 11b of the control board 11. When the direction-regulating projection 36b is inserted into the mounting hole 13b, its tip may be slightly recessed from the back surface 11b of the control board 11. When the direction-regulating projection 36b is inserted into the mounting hole 13b, its tip may be flush with the back surface 11b of the control board 11.

[0054] The relationship between these directional restricting protrusions 36a and 36b and the mounting holes 13a and 13b can have conditions similar to those of the relationship between the directional restricting recesses 35a and 35b and the directional restricting protrusions 42a and 42b described above. The conditions similar to those of the relationship are the contour shape when viewed in the X-axis direction, Y-axis direction, and Z-axis direction.

[0055] The direction-regulating protrusions 36a and 36b secure the mounting kit 30 to the control board 11. Specifically, the tips of the direction-regulating protrusions 36a and 36b are fixed to the back surface 11b surrounding the mounting holes 13a and 13b. The tip of the direction-regulating protrusion 36a is fixed to the back surface 11b surrounding the mounting hole 13a. The tip of the direction-regulating protrusion 36b is fixed to the back surface 11b surrounding the mounting hole 13b. The direction-regulating protrusions 36a and 36b can be fixed by potting. Potting involves applying a viscous resin and then fixing it by curing or the like. Alternatively, the direction-regulating protrusions 36a and 36b can be fixed by forming threads on their outer surfaces and screwing them together with nuts.

[0056] The upright portion 33 is located at the front end of part B 31 in the Y-axis direction. The upright portion 33 stands upright from the mounting portion 32 in a direction that is further away from the control board 11 in the Z-axis direction. The upright portion 33 has a substantially rectangular cross-section in the XY plane. The upright portion 33 is formed integrally with the mounting portion 32.

[0057] The upright portion 33 has an inward contact surface 33a. The inward contact surface 33a is the side surface of the upright portion 33 that is close to the center line C. The inward contact surface 33a is a plane. The inward contact surface 33a faces the inward contact surface 33a of the paired B part 31 across the center line C. The inward contact surface 33a is parallel to the center line C. The inward contact surface 33a extends in the Z-axis direction. The inward contact surface 33a extends in the Y-axis direction. In the paired inward contact surfaces 33a across the center line C, the separation distance Td in the X-axis direction is set in advance to a predetermined range, as will be described later.

[0058] The inward contact surface 33a constitutes a mounting position clamping restriction section. The inward contact surface 33a constitutes a mounting position lateral clamping restriction section. The pair of inward-facing contact surfaces 33a contact the lateral ends of the transmission module board 20, respectively, during installation. The pair of inward-facing contact surfaces 33a restrict the tilt of the transmission module board 20 from the Y-axis direction to the X-axis direction. The inward-facing contact surfaces 33a are set to a predetermined range in advance, as described later, with respect to the Y-axis dimension Ta1.

[0059] The protruding portion 34 is located at the upper end of the upright portion 33 in the Z-axis direction. The protruding portion 34 extends from the upper end of the upright portion 33 in the X-axis direction toward the center line C. The dimensions of the protruding portion 34 extending from the upright portion 33 in the X-axis direction are not particularly limited. The dimensions of the protruding portion 34 in the X-axis direction are the distance from the inward contact surface 33a to the tip of the protruding portion 34. The dimensions of the protruding portion 34 in the X-axis direction are within a range that allows the transmission module substrate 20 to be positioned, as will be described later.

[0060] The thickness dimension of the overhang 34 in the Z-axis direction is not particularly limited. The thickness dimension of the overhang 34 is within a range that has sufficient strength to restrict the position of the transmission module substrate 20, as will be described later. The length dimension of the overhang 34 in the Y-axis direction is set to be equal to the dimension Ta1 of the inward contact surface 33a.

[0061] The protruding portion 34 has a downward contact slope 34a and a bottom surface 34b. Both the downward contact slope 34a and the bottom surface 34b are formed downward in the Z-axis direction on the protruding portion 34. The downward contact slope 34a and the bottom surface 34b are adjacent in the Y-axis direction. The downward contact slope 34a and the bottom surface 34b are located continuously in the Y-axis direction. Both the downward contact slope 34a and the bottom surface 34b are planes.

[0062] The downward contact slope 34a is formed on the protruding portion 34 at a position close to the mounting portion 32 in the Y-axis direction. The lower surface 34b is formed on the protruding portion 34 at a position spaced apart from the mounting portion 32 in the Y-axis direction. The downward contact slope 34a has its front end in the Y-axis direction connected to the rear end of the lower surface 34b.

[0063] The lower surface 34b is parallel to the mounting surface 32a. The lower surface 34b is parallel to the substrate surface 11a. The lower surface 34b is planar. The lower surface 34b extends along the XY plane. The length dimension Ta2 of the lower surface 34b in the Y-axis direction is smaller than the dimension Ta1 of the inward contact surface 33a in the Y-axis direction.

[0064] The lower surface 34b is spaced apart from the mounting surface 32a in the Z-axis direction. The protruding portion 34 and the mounting portion 32 are spaced apart in the Z-axis direction. The distance between the lower surface 34b and the mounting surface 32a in the Z-axis direction is equal to the thickness dimension of the transmission module substrate 20.

[0065] The lower surface 34b is spaced apart from the substrate surface 11a in the Z-axis direction when part B 31 is attached to the control board 11. The protruding portion 34 and the substrate surface 11a are spaced apart in the Z-axis direction. The height dimension Tb in the Z-axis direction from the substrate surface 11a to the lower surface 34b is equal to the height dimension of the inward contact surface 33a. The distance Tb in the Z-axis direction between the lower surface 34b and the substrate surface 11a is equal to the distance in the Z-axis direction between the substrate surface 11a and the substrate surface 20a.

[0066] The downward contact slope 34a is parallel to the Y-axis. The downward contact slope 34a is inclined with respect to the lower surface 34b. The downward contact slope 34a is inclined upward in the Z-axis direction as it moves away from the lower surface 34b in the Y-axis direction. In the Y-axis direction, the downward contact slope 34a is inclined upward from the end connected to the lower surface 34b toward the end of the protruding portion 34. In the Y-axis direction, the downward contact slope 34a is inclined such that the distance from the substrate surface 11a decreases as it approaches the substrate-side connector 12. The downward contact slope 34a has a rectangular profile. The downward contact slope 34a constitutes a vertical mounting position restricting section. The downward contact slope 34a constitutes a vertical mounting position clamping restricting section. When the transmission module board 20 is mounted, the downward contact slope 34a contacts the board surface 20a, which is near the lateral ends of the transmission module board 20.

[0067] Part B 31 has an upward contact slope 37a. The upward contact slope 37a constitutes a vertical mounting position restricting section. The upward contact slope 37a constitutes a vertical mounting position clamping restricting section. When the transmission module board 20 is mounted, the upward contact slope 37a contacts the back surface 20b, which is near the lateral ends of the transmission module board 20.

[0068] The upward contact slope 37a is formed on the mounting portion 32. The upward contact slope 37a is adjacent to the front end of the mounting surface 32a in the Y-axis direction. The upward contact slope 37a is a plane. In the X-axis direction, the upward contact slope 37a is closer to the center line C than the mounting contact surface 32c. When viewed in the Z-axis direction, the upward contact slope 37a is adjacent to the mounting contact surface 32c. When viewed in the Z-axis direction, the upward contact slope 37a is located further away from the substrate-side connector 12 in the Y-axis direction than the upright portion 33.

[0069] The upward contact slope 37a is inclined in the Z-axis direction. The rear end of the upward contact slope 37a in the Y-axis direction is connected to the front end of the mounting surface 32a. The front end of the upward contact slope 37a in the Y-axis direction is in contact with the substrate surface 11a. The upward contact slope 37a is parallel to the Y-axis. The upward contact slope 37a is inclined with respect to the mounting surface 32a.

[0070] The upward contact slope 37a is inclined downward in the Z-axis direction as it moves away from the mounting surface 32a in the Y-axis direction. The upward contact slope 37a is inclined downward in the Y-axis direction from the rear end connected to the mounting surface 32a towards the upright portion 33. The upward contact slope 37a is inclined in the Y-axis direction as it approaches the substrate side connector 12, so as it moves closer to the substrate surface 11a, the distance between it and the substrate surface 11a decreases. The upward contact slope 37a has a rectangular contour.

[0071] The upward contact slope 37a has a rectangular contour when viewed in the Z-axis direction, and the ends that are spaced apart from the center line C coincide with the contour of the mounting contact surface 32c when viewed in the Z-axis direction. The upward abutment slope 37a has a front end in the Y-axis direction that extends in the X-axis direction. The upward abutment slope 37a has a front end in the Y-axis direction that is spaced apart from the rear end of the overhang 34 as viewed in the Z-axis direction. The upward abutment slope 37a has a front end in the Y-axis direction that is parallel to the rear end of the overhang 34 as viewed in the Z-axis direction.

[0072] The upward contact slope 37a faces the downward contact slope 34a. The upward contact slope 37a and the downward contact slope 34a come into contact with the vicinity of both lateral ends of the transmission module board 20 when the transmission module board 20 is installed. The upward contact slope 37a and the downward contact slope 34a form a vertical mounting position restricting section as a pair. The upward contact slope 37a and the downward contact slope 34a form a clamping section for mounting position as a pair. The upward contact slope 37a and the downward contact slope 34a form a vertical clamping section for mounting position as a pair.

[0073] As a result, the upward contact slope 37a and the downward contact slope 34a restrict the insertion and removal angle of the transmission module board 20 with respect to the control board 11 when the transmission module board 20 is installed. The upward contact slope 37a and the downward contact slope 34a restrict the angle of the transmission module board 20 with respect to the control board 11 in the YZ plane when the transmission module board 20 is installed.

[0074] The T-part 41 extends in the Y-axis direction. The T-part 41 has a length dimension in the Y-axis direction that is approximately equal to that of the mounting portion 32. The front end of the T-part 41 in the Y-axis direction is approximately in contact with the rear end of the upright portion 33. The rear end of the T-part 41 in the Y-axis direction is approximately at the same position as the rear end of the mounting portion 32. The T-part 41 has a width dimension that is slightly smaller than or approximately equal to that of the mounting portion 32 in the X-axis direction. The lateral end of the T-part 41, which is spaced away from the center line C in the X-axis direction, is positioned to coincide with the lateral end of the mounting portion 32 when viewed in the Z-axis direction.

[0075] The T-part 41 has a mounting contact surface 41b, a mounting pressing contact surface 41c, a direction-regulating projection 42a, a direction-regulating projection 42b, and a through hole for the bolt B1.

[0076] The mounting contact surface 41b and the mounting pressing contact surface 41c are the lower surfaces of the T-part 41 that are facing downwards in the Z-axis direction. The mounting contact surface 41b is formed in a flat plane. The mounting contact surface 41b has a contour shape that corresponds to the mounting contact surface 32c when viewed in the Z-axis direction. The entire area of ​​the mounting contact surface 41b is in contact with the mounting contact surface 32c. The mounting contact surface 41b is in contact with part B 31 outward in the X-axis direction from the lateral ends of the transmission module substrate 20.

[0077] The mounting contact surface 41c is formed on a flat surface. The mounting contact surface 41c is adjacent to the mounting contact surface 41b. The mounting contact surface 41c has a region that overlaps with the mounting surface 32a when viewed in the Z-axis direction. The boundary line between the mounting contact surface 41c and the mounting contact surface 41b has a portion that overlaps with the boundary line G between the mounting contact surface 32c and the mounting surface 32a when viewed in the Z-axis direction. The mounting contact surface 41c is located inward, closer to the center line C in the X-axis direction than the mounting contact surface 41b.

[0078] The mounting contact surface 41c is located above the mounting contact surface 41b, spaced further away from the substrate surface 11a in the Z-axis direction. A step is formed between the mounting contact surface 41c and the mounting contact surface 41b. The mounting contact surface 41c contacts the substrate surface 20a at both lateral ends of the transmission module substrate 20.

[0079] Direction-regulating protrusions 42a and 42b are formed on the mounting contact surface 41b. Direction-regulating protrusions 42a and 42b constitute the mounting position direction-regulating portion. The directional restricting protrusions 42a and 42b are positioned spaced apart from each other in the X-axis direction on the mounting contact surface 41c. The directional restricting protrusions 42a and 42b are located close to both ends of the mounting contact surface 41b in the X-axis direction. Both the directional restricting protrusions 42a and 42b protrude downward from the mounting contact surface 41b in the Z-axis direction.

[0080] The direction-restricting protrusions 42a and 42b have different cross-sectional contour shapes when viewed in the Z-axis direction. For example, the cross-sectional contour shape of the direction-restricting protrusion 42a can be made shorter in the X-axis direction dimension than the cross-sectional contour shape of the direction-restricting protrusion 42b. Alternatively, the cross-sectional contour shape of the direction-restricting protrusion 42a can be made longer in the Y-axis direction dimension than the contour shape of the direction-restricting protrusion 42b. Such cross-sectional contour shapes are just examples; it is sufficient that the cross-sectional contour shapes of the direction-restricting protrusion 42a and 42b are different, and that there is a difference in relative shape such that the T-part 41 cannot be attached and fixed to the B-part 31 if the T-part 41 is placed on the B-part 31 and the substrate surface 20a in the wrong orientation (position).

[0081] Direction-restricting protrusions 42a and 42b correspond to direction-restricting recesses 35a and 35b formed in part B 31. Direction-restricting protrusions 42a and 42b can be fitted into direction-restricting recesses 35a and 35b formed in part B 31. Direction-restricting protrusions 42a and 42b can be stored in direction-restricting recesses 35a and 35b when part T 41 is fitted into part B 31 in the correct position.

[0082] Here, the fact that the direction-restricting projection 42a can be housed in the direction-restricting recess 35a, and that the direction-restricting projection 42b can be housed in the direction-restricting recess 35b, corresponds to the correct orientation in which the T part 41 and the B part 31 can fix the transmission module board 20 together. In other words, the correct orientation of the T part 41 and the B part 31 corresponds to a state in which the mounting contact surface 41b and the mounting contact surface 32c are in parallel contact, and the mounting pressing contact surface 41c and the board surface 20a are in parallel contact. The direction-restricting projection 42a and the direction-restricting recess 35a, and the direction-restricting projection 42b and the direction-restricting recess 35b have such fitting conditions.

[0083] Furthermore, the directional restricting projection 42a and the directional restricting projection 42b may have different separation distances from each other in the Y-axis direction with respect to the fastening position of the bolt B1 located near the center of the mounting contact surface 41b. The direction-regulating projection 42a, the fastening position of the bolt B1, and the direction-regulating projection 42b are positioned in this order in the Y-axis direction. In the Y-axis direction, the distance between the bolt B1 and the direction-regulating projection 42a can be different from the distance between the bolt B1 and the direction-regulating projection 42b. Note that bolts B and B1 can be positioned at different locations in the Z-axis direction. Bolts B and B1 can also be used interchangeably.

[0084] Furthermore, the direction-restricting protrusions 42a and 42b may be arranged differently in the X-axis direction. Arrangement differently in the X-axis direction means that the distance between the center line C and the direction-restricting protrusion 42a is different from the distance between the center line C and the direction-restricting protrusion 42b in the X-axis direction.

[0085] The direction-restricting protrusions 42a and 42b can have different cross-sectional contour shapes when viewed in the Z-axis direction. Although both the direction-restricting protrusions 42a and 42b are shown as rectangular cross-sectional contours, they are not limited to this shape. For example, the direction-restricting protrusion 42a can have a rectangular contour shape, while the direction-restricting protrusion 42b can have a triangular cross-sectional contour shape that does not fit within this rectangle.

[0086] The Z-axis oriented regulating projection 42a and the Z-axis oriented regulating projection 42b may have different lengths. The Z-axis oriented regulating recess 35a and the Z-axis oriented regulating recess 35b may have different depths. For example, the length of the Z-axis oriented regulating projection 42a may be smaller than the length of the Z-axis oriented regulating projection 42b. For example, the length of the Z-axis oriented regulating projection 42a corresponds to the depth of the Z-axis regulating recess 35a. The length of the Z-axis oriented regulating projection 42b corresponds to the depth of the Z-axis regulating recess 35b.

[0087] In this case, if part T 41 is placed on part B 31 in the wrong orientation, the direction-restricting projection 42b, which has a larger Z-axis dimension, is inserted into the direction-restricting recess 35a, which has a smaller Z-axis dimension. The direction-restricting projection 42b abuts against the bottom of the direction-restricting recess 35a. The mounting contact surface 41b and the mounting contact surface 32c are tilted at an angle. A region is created between the mounting contact surface 41b and the mounting contact surface 32c that does not contact each other. The mounting contact surface 41b and the mounting contact surface 32c do not make full contact with each other. Also, the mounting pressing contact surface 41c and the back surface 20b do not make full contact with each other. This makes it possible to determine if the T part 41 is placed on the B part 31 in the wrong orientation. Note that the length dimension in the Z-axis direction between the direction regulating protrusion 42a and the direction regulating protrusion 42b is not limited to this condition.

[0088] The mounting kit 30 is configured to be symmetrical with respect to the center line C, but the direction-restricting protrusions 42a and 42b do not conform to this configuration, similar to the direction-restricting recesses 35a and 35b. In other words, the T part 41 that can be attached to the B part 31 on the right side of Figure 1 cannot be attached to the B part 31 on the left side of Figure 1.

[0089] To achieve this configuration, in Figure 4, the directional restricting protrusions 42a and 42b shown above the center line C have different contour shapes and / or arrangements compared to the directional restricting protrusions 42a1 and 42b1 shown below the center line C. This difference in contour shape and / or arrangement can be based on the conditions for fitting the directional restricting protrusions 42a and 42b described above. The direction-regulating protrusions 42a1, 42b1, 42a, and 42b serve as mounting position direction-regulating parts, regulating the combined position and orientation of the T part 41 attached to the B part 31.

[0090] The following describes a method for attaching the transmission module board 20 to the control board 11 using the mounting kit 30 in the substrate device of this embodiment. Figure 5 is a top view showing the control board in the substrate device of this embodiment. Figure 6 is a front view showing the control board in the substrate device of this embodiment. Figure 7 is a side view showing the control board in the substrate device of this embodiment.

[0091] First, prepare the control board 11. The control board 11 is equipped with a board-side connector 12. The arrangement of the board-side connector 12 determines the center line C. The control board 11 has mounting holes 13a, 13b, and 13c formed therein.

[0092] Figure 8 is a top view showing the control board of the substrate device of this embodiment with part B attached. Figure 9 is a front view showing the control board of the substrate device of this embodiment with part B attached. Figure 10 is a side view showing the control board of the substrate device of this embodiment with part B attached. Next, a pair of B parts 31 are attached to the control board 11.

[0093] The combined position and orientation of part B 31 relative to the control board 11 are restricted by the mounting position direction restricting portion. The combined position and orientation of part B 31 relative to the control board 11 are restricted with respect to the control board 11 by the direction restricting protrusions 36a and 36b, and the mounting holes 13a and 13b.

[0094] Part B 31 is positioned so that the upright portion 33 is close to the board-side connector 12 in the Y-axis direction. Part B 31 is positioned so that the protruding portion 34 extends toward the center line C in the X-axis direction. Insert the directional regulating projection 36a corresponding to the mounting hole 13a. Insert the directional regulating projection 36b corresponding to the mounting hole 13b. This regulates the position of part B 31 in the correct position relative to the board-side connector 12. The directional regulating projection 36a is fixed to the control board 11 by a method such as potting. The directional regulating projection 36b is fixed to the control board 11 by a method such as potting. Bolt B is fastened to the mounting hole 13c. This secures the pair of B parts 31 to the control board 11 in the correct position.

[0095] Figure 11 is a top view showing the transmission module board attached to part B of the substrate device according to this embodiment. Figure 12 is a front view showing the transmission module board attached to part B of the substrate device according to this embodiment. Figure 13 is a side view showing the transmission module board attached to part B of the substrate device according to this embodiment. Next, the transmission module board 20 is attached to the pair of B parts 31.

[0096] The insertion position of the transmission-side connector 22 into the board-side connector 12 is maintained in the correct position by the mounting position clamping regulating part, allowing for insertion. The insertion orientation of the transmission-side connector 22 into the board-side connector 12 in the X-axis direction is maintained in the correct position by the mounting position lateral clamping restrictor, allowing for insertion. The insertion orientation of the transmission-side connector 22 into the board-side connector 12 in the Z-axis direction is maintained in the correct position by the mounting position vertical clamping restrictor and the mounting surface 32a, allowing for insertion.

[0097] The transmission module board 20 is moved along the Y-axis so that the transmission-side connector 22 faces forward. The transmission module board 20 is inserted so that the transmission-side connector 22 passes between the upward contact slope 37a and the downward contact slope 34a. The upward contact slope 37a and the downward contact slope 34a form a pair that constitutes a vertical mounting position restricting section. The transmission module board 20 is inserted so that the transmission-side connector 22 passes between the inward contact surfaces 33a located on both sides of the center line C. The inward contact surfaces 33a located on both sides of the center line C form a pair that constitutes a horizontal mounting position restricting section.

[0098] When the transmission-side connector 22 is inserted into the mounting position vertical clamping restriction section, the transmission module board 20 is tilted such that the board surface 20a is inclined with respect to the board surface 11a. When the transmission-side connector 22 is inserted into the mounting position vertical clamping restriction section, the board surface 20a is tilted such that the external connection connector 21 is spaced apart from the board surface 11a in the Z-axis direction relative to the transmission-side connector 22. When the transmission-side connector 22 is inserted, the transmission module board 20 is positioned such that both lateral ends of the transmission-side connector 22 in the X-axis direction are equidistant from both lateral ends of the board-side connector 12 in the X-axis direction in the Y-axis direction.

[0099] In this position, the transmission module board 20 is moved further forward in the Y-axis direction. At the same time, the inclination of the transmission module board 20 is reduced so that the board surface 20a becomes closer to parallel with the board surface 11a. The transmission-side connector 22 gradually moves closer to the board-side connector 12.

[0100] As the transmission module board 20 moves further forward in the Y-axis direction, both lateral ends of the transmission module board 20 in the X-axis direction are sandwiched between the downward contact slope 34a and the upward contact slope 37a. The downward contact slope 34a contacts the board surface 20a. The upward contact slope 37a contacts the back surface 20b. Alternatively, the transmission module board 20 contacts either the downward contact slope 34a or the upward contact slope 37a. Alternatively, the transmission module board 20 contacts both the downward contact slope 34a and the upward contact slope 37a. As a result, the transmission module substrate 20 moves forward in the Y-axis direction while the substrate surface 20a maintains a predetermined inclination angle range with respect to the substrate surface 11a.

[0101] Simultaneously, as the transmission module board 20 moves further forward in the Y-axis direction, both lateral ends of the transmission module board 20 in the X-axis direction are sandwiched between the inward contact surfaces 33a in the X-axis direction. The orientation of both lateral ends of the transmission module board 20 in the X-axis direction is controlled along the inward contact surfaces 33a. Both lateral ends of the transmission module board 20 in the X-axis direction maintain their orientation along the inward contact surfaces 33a. In other words, both lateral ends of the transmission module board 20 in the X-axis direction maintain their orientation along the Y-axis direction.

[0102] As a result, the transmission module board 20 moves forward in the Y-axis direction while the transmission-side connector 22 and the board-side connector 12 maintain a position that is approximately parallel to each other when viewed in the Z-axis direction. At the same time, the transmission module board 20 moves forward in the Y-axis direction while the transmission-side connector 22 and the board-side connector 12 maintain the correct position in the X-axis direction.

[0103] As the transmission module board 20 moves further forward in the Y-axis direction, the transmission-side connector 22 moves away from the protruding portion 34 in the Y-axis direction. The transmission-side connector 22 comes close to the tip of the pin 12a of the board-side connector 12. When the inclination of the transmission module substrate 20 is reduced, the back surface 20b at the lateral end of the transmission module substrate 20 comes into contact with the mounting surface 32a. The back surface 20b at the lateral end of the transmission module substrate 20 comes into contact only with the rear end of the upward contact slope 37a.

[0104] Simultaneously, reducing the inclination of the transmission module substrate 20 causes the substrate surface 20a at its lateral end to be aligned with the lower surface 34b of the protruding portion 34. Alternatively, reducing the inclination of the transmission module substrate 20 causes the substrate surface 20a at its lateral end to abut against the lower surface 34b of the protruding portion 34. The substrate surface 20a at its lateral end of the transmission module substrate 20 contacts only the front end of the downward contact slope 34a.

[0105] As a result, the transmission module board 20 has a substrate surface 20a that is parallel to the substrate surface 11a. The transmission module board 20 has its substrate surface 20a in contact with the lower surface 34b. The transmission module board 20 has its back surface 20b in contact with the mounting surface 32a. The transmission module board 20 has both lateral ends sandwiched between the lower surface 34b and the mounting surface 32a.

[0106] The transmission module board 20 is positioned so that the transmission-side connector 22 is in the correct insertion position relative to the board-side connector 12. In other words, the transmission module board 20 is positioned so that the insertion direction of the transmission-side connector 22 is parallel to the pins 12a. The transmission module board 20 is positioned so that the insertion position of the transmission-side connector 22 corresponds to the X-axis direction relative to the numerous pins 12a. The transmission module board 20 is positioned so that the insertion position of the transmission-side connector 22 corresponds to the Z-axis direction relative to the multi-stage pins 12a.

[0107] As the transmission module board 20 moves further forward in the Y-axis direction, it moves in the Y-axis direction while maintaining the state in which its back surface 20b is in contact with the mounting surface 32a. Both lateral ends of the transmission module board 20 in the X-axis direction move in the Y-axis direction while maintaining their orientation along the inward contact surface 33a. As a result, when the transmission module board 20 moves further forward in the Y-axis direction, the transmission-side connector 22 and the board-side connector 12 are inserted in the correct insertion position. This prevents misinsertion of the transmission-side connector 22 and the board-side connector 12.

[0108] With the transmission-side connector 22 and the board-side connector 12 inserted, the transmission module board 20 does not cover the mounting contact surface 32c. The lateral edge of the transmission module board 20 is located along the boundary line G. With the transmission-side connector 22 and the board-side connector 12 inserted, the transmission module board 20 has its board surface 20a parallel to the board surface 11a. The transmission module board 20 has its board surface 20a in contact with the bottom surface 34b. The transmission module board 20 has its back surface 20b in contact with the mounting surface 32a. The transmission module board 20 maintains a state where both lateral ends are sandwiched between the bottom surface 34b and the mounting surface 32a.

[0109] Next, as shown in Figures 1 to 3, a pair of T parts 41 are attached to the B part 31 and the transmission module board 20. The combined position and orientation of part T 41 relative to part B 31 are restricted with respect to the control board 11 by the mounting position direction restricting protrusions 42a1, 42b1, 42a, and 42b. The combined position and orientation of part T 41 are restricted with respect to part B 31 and the transmission module board 20 by the mounting position direction restricting section.

[0110] The T-part 41 is positioned such that the directional regulating protrusion 42a is close to the substrate-side connector 12 in the Y-axis direction. The T-part 41 is positioned such that the mounting contact surface 41c is closer to the center line C than the mounting contact surface 41b in the X-axis direction. Insert the direction-restricting projection 42a corresponding to the direction-restricting recess 35a. Insert the direction-restricting projection 42b corresponding to the direction-restricting recess 35b.

[0111] Similarly, insert the direction-restricting projection 42a1 corresponding to the direction-restricting recess 35a1. Insert the direction-restricting projection 42b1 corresponding to the direction-restricting recess 35b1. These measures ensure that the T-part 41 is positioned correctly relative to the B-part 31 and the transmission module board 20 at both sides of the center line C.

[0112] Furthermore, the T part 41 is pressed downward in the Z-axis direction against the B part 31 and the transmission module substrate 20. The mounting contact surface 41b is brought into contact with the mounting surface 32a. The mounting pressing contact surface 41c is brought into contact with the substrate surface 20a. The step formed by the mounting pressing contact surface 41c and the mounting contact surface 41b is brought into contact with both lateral edges of the transmission module substrate 20. Furthermore, bolt B1 is fastened to complete the assembly of the circuit board device 10.

[0113] In this embodiment, the substrate device 10 allows for easy and correct setting of the mounting position and orientation of part B 31 relative to the control board 11 by the mounting position orientation regulating unit. The substrate device 10 also allows for easy and correct setting of the mounting position and orientation of part T 41 relative to the control board 11 and part B 31 by the mounting position orientation regulating unit.

[0114] This allows the transmission-side connector 22 and the board-side connector 12 to be inserted in the correct orientation. It prevents the transmission-side connector 22 and the board-side connector 12 from being inserted in an incorrect orientation. It also makes it easy to prevent incorrect insertion of the transmission-side connector 22 and the board-side connector 12.

[0115] The substrate device 10 allows for easy and correct setting of the mounting position and orientation of the transmission module board 20 relative to the control board 11 by the mounting position clamping section. The substrate device 10 allows for easy and correct setting of the mounting position and orientation of the transmission module board 20 in the Z-axis direction relative to the control board 11 by the mounting position vertical clamping restrictor. The substrate device 10 also allows for easy and correct setting of the mounting position and orientation of the transmission module board 20 in the X-axis direction relative to the control board 11 by the mounting position lateral clamping restrictor.

[0116] The mounting kit 30 prevents mis-insertion of the transmission-side connector 22, which has a multi-stage configuration of pins 12a, and the board-side connector 12 in the board device 10. The mounting kit 30 prevents mis-insertion of the transmission-side connector 22, which has a multi-stage configuration of pins 12a, and the board-side connector 12 in the Z-axis direction.

[0117] The mounting kit 30 in the board device 10 prevents the transmission-side connector 22 and the board-side connector 12, which have a large number of pins 12a arranged in the X-axis direction, from being misinserted into adjacent pins 12a along the board surface 11a. The mounting kit 30 in the board device 10 prevents the transmission-side connector 22 and the board-side connector 12, which have a multi-stage arrangement of pins 12a, from being misinserted in the X-axis direction.

[0118] In the mounting kit 30, the board device 10 has an upward contact slope 37a and a downward contact slope 34a that are inclined opposite to each other, so that the movement of the transmission module board 20 is not obstructed when the transmission module board 20 is mounted. The board device 10 makes it easier to insert the transmission module board 20. The board device 10 improves ease of assembly.

[0119] When the transmission-side connector 22 and the board-side connector 12 are inserted into the board device 10, the transmission module board 20 is positioned so that its board surface 20a is parallel to the board surface 11a. The board device 10 ensures that the board surface 20a of the transmission module board 20 is in contact with the lower surface 34b. The board device 10 ensures that the back surface 20b of the transmission module board 20 is in contact with the mounting surface 32a. The board device 10 maintains a state in which both lateral ends of the transmission module board 20 are sandwiched between the lower surface 34b and the mounting surface 32a. This ensures that the insertion direction of the transmission module board 20 does not deviate in the Z-axis direction.

[0120] When inserting the transmission-side connector 22 into the board-side connector 12, the board device 10 causes the transmission module board 20 to move between the inward contact surfaces 33a located on both sides of the center line C. The board device 10 ensures that both lateral ends of the transmission module board 20 move along the inward contact surfaces 33a located on both sides of the center line C. The board device 10 maintains a state in which both lateral ends of the transmission module board 20 are sandwiched between the inward contact surfaces 33a located on both sides of the center line C. This ensures that the insertion direction of the transmission module board 20 does not deviate in the X-axis direction.

[0121] The circuit board device 10 does not require a step to check for incorrect insertion during the mounting process of the transmission module board 20 during its assembly process. Power can be turned on and the device can be shipped without performing a step to check whether the transmission-side connector 22 and the board-side connector 12 are correctly inserted. As a result, the control board 11 or the transmission module board 20 will not be damaged by overvoltage or the like due to incorrect insertion of the transmission-side connector 22 and the board-side connector 12.

[0122] The substrate device 10 can achieve the above effects simply by replacing the mounting kit 30. Furthermore, the substrate device 10 does not require the use of a jig for checking for incorrect insertion. In addition, the substrate device 10 does not require the use of a jig or the like for regulating the insertion orientation between the transmission-side connector 22 and the substrate-side connector 12. The substrate device 10 can achieve the above effects without increasing the number of components.

[0123] The following describes the dimensional settings for the mounting kit 30.

[0124] Figure 14 is a top view showing the relationship between the dimensions of the substrate device in this embodiment. Figure 15 is a side view showing the relationship between the dimensions of the substrate device in this embodiment. For the mounting kit 30, the following dimensions are set as shown in Figures 4, 14, and 15. • Length dimension Ta1 of the inward contact surface 33a in the Y-axis direction • Length dimension Ta2 of the lower surface 34b in the Y-axis direction • Height dimension Tb from substrate surface 11a to bottom surface 34b in the Z-axis direction • Distance Tc between the front end of part B 31 and the tip of pin 12a in the Y-axis direction • Distance Td between the inward contact surfaces 33a with respect to the center line C in the X-axis direction

[0125] The height dimension Tb is set to prevent the transmission module board 20 from moving in the Z-axis direction. The spacing distance Td is set to prevent the transmission module board 20 from moving in the X-axis direction. The spacing distance Tc is set to prevent incorrect insertion of the transmission-side connector 22 and the board-side connector 12. The length dimension Ta2 is set to position the transmission module board 20 along the center line C. The length dimension Ta1 is set to provide the necessary strength to hold the transmission module board 20 in the Z-axis direction.

[0126] Here, the separation distance Td is defined as the width dimension Tf of the transmission module substrate 20 in the X-axis direction and the separation distance Te between adjacent pins 12a in the X-axis direction. Td = Tf + Te / 2 Let the relationship satisfy the following conditions.

[0127] The separation distance Tb is determined by the thickness dimension Tg of the mounting section 32 in the Z-axis direction, the thickness dimension Tt of the transmission module substrate 20, and a small amount of play α. Tb = Tg + Tt + α Let the relationship satisfy the following conditions. Furthermore, the separation distance Tb is greater than the thickness dimension Tt22 in the Z-axis direction of the transmission-side connector 22 (Figure 15).

[0128] The relationship between the length dimension Ta1 and the separation distance Tc is defined as follows: First, the range of insertion angles θ for the transmission module board 20, whose orientation is restricted by the mounting position lateral clamping restriction section, is set to a range in which the transmission-side connector 22 can be correctly inserted into the pins 12a. When setting the angle θ, the separation distance Td should be set as described above. When setting the angle θ, the separation distance Tc is determined. The position in the X-axis direction of the front end of the upright portion 33, which abuts against the lateral end of the transmission module substrate 20, is defined by setting the angle θ and the separation distance Tc. (Figure 14) At the same time, the position in the X-axis direction of the rear end of the upright portion 33, which abuts against the lateral end of the transmission module board 20 on the opposite side of the center line C, is defined. Furthermore, the positions where the respective surfaces of the mounting position regulating section intersect are set by extending them.

[0129] For the mounting kit 30, set the following values ​​as shown in Figure 15. • Angle φ1 between the upward contact inclined surface 37a and the substrate surface 11a • Angle φ2 between the downward contact slope 34a and the substrate surface 11a Here, the range of the angle φ between the substrate surface 20a of the transmission module substrate 20 and the substrate surface 11a during insertion is set to a range in which the transmission module substrate 20 can be inserted relative to the mounting position vertical clamping restriction portion. Angle φ1 is equal to or slightly less than the maximum value of angle φ. The angle φ2 is equal to or slightly greater than the minimum value of the angle φ. In Figure 15, the upper surface of the transmission-side connector 22 is in contact with the entire surface of the downward contact slope 34a. The upper surface of the transmission-side connector 22 is parallel to the downward contact slope 34a. Angle φ is equal to angle φ2. Furthermore, in Figure 15, the lower surface of the transmission-side connector 22 has its front end in the Y-axis direction in contact with the substrate surface 11a. The lower surface of the transmission-side connector 22 has its rear end in the Y-axis direction spaced apart from the upward contact slope 37a.
