Component mounting structure

Abstract

To provide a component mounting structure capable of suppressing an increase in the size of a product and sufficiently pressing a plurality of components with a small number of components.SOLUTION: A slit 50 is provided between the first pressing part 23A and the second pressing part 23B, and the slit 50 reaches at least the step part 22. Therefore, the transmission path of the displacement between the first pressing part 23A and the second pressing part 23B is divided by the slit 50 reaching the step part 22. Therefore, the slit 50 can prevent the displacement caused by one pressing portion pressing one component from interfering with the other pressing portion. For this reason, it is possible to obtain a sufficient pressing force in each of the pressing portions 10A and 10B without separating the first component 23A and the second component 23B from each other or dividing the pressing member.SELECTED DRAWING: Figure 3

Description

[Technical Field]

[0001] The present disclosure relates to a component mounting structure. [Background technology]

[0002] Conventionally, a component mounting structure in which components mounted on a housing are supported by a pressing member is known (for example, Patent Document 1). In this component mounting structure, multiple components are pressed by multiple pressing portions provided on one support portion. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-63200 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the component mounting structure described above, when components are placed close to each other, the pressing portions are also placed close to each other. In this case, a problem occurs in that the pressing force of one pressing portion on another component is reduced due to the influence of displacement caused by stress when the other pressing portion presses the other component. If the components are placed farther apart or the pressing member is divided into multiple pieces to solve this problem, problems such as an increase in product size and the number of components arise.

[0005] An object of the present disclosure is to provide a component mounting structure that prevents the product from becoming larger and that can sufficiently press multiple components with a small number of components. [Means for solving the problem]

[0006] A component mounting structure according to one embodiment of the present disclosure includes a housing, a first component arranged in the housing, a second component adjacent to the first component, and a pressing member that presses the first component and the second component toward the housing, the pressing member including a support portion fixed to the housing, a step portion extending in a first direction from the support portion toward the opposite side of the housing, an edge portion extending from an end of the step portion on the opposite side of the housing in a second direction intersecting the first direction, a first pressing portion protruding from the edge portion and pressing the first component, and a second pressing portion that presses the second component, a slit being provided between the first pressing portion and the second pressing portion, the slit reaching at least as far as the step portion.

[0007] In a component mounting structure according to one embodiment of the present disclosure, the pressing member includes a support portion fixed to the housing, a step portion extending in a first direction from the support portion toward the opposite side of the housing, an edge portion extending from an end of the step portion on the opposite side of the housing in a second direction intersecting the first direction, and a first pressing portion protruding from the edge portion to press the first component and a second pressing portion protruding from the edge portion to press the second component. This allows the pressing member to support the first component and the second component with a single member. A slit is provided between the first pressing portion and the second pressing portion, and the slit reaches at least the step portion. Therefore, the slit that reaches the step portion separates the path of displacement between the first pressing portion and the second pressing portion. Therefore, the slit can prevent displacement generated when one pressing portion presses one component from interfering with the other pressing portion. Therefore, sufficient pressing force can be obtained at each pressing portion without increasing the distance between the first and second components or dividing the pressing member. As a result, the product size can be prevented from increasing and multiple components can be pressed sufficiently with a small number of components.

[0008] The slit may extend from the center of the step portion toward the support portion in the first direction. In this case, half of the step portion in the first direction is divided by the slit. This further reduces the path of displacement transmission between the first pressing portion and the second pressing portion.

[0009] The slit may reach the boundary between the step portion and the support portion. In this case, the entire area of ​​the step portion in the first direction is divided by the slit. This further reduces the number of paths through which displacement is transmitted between the first pressing portion and the second pressing portion.

[0010] The slit may reach the support portion. In this case, the entire area of ​​the step portion in the first direction and the boundary portion are divided by the slit. This further reduces the transmission path of displacement between the first pressing portion and the second pressing portion.

[0011] The support portion may be fixed to the housing via a fixing portion, in which case elastic deformation can be easily generated at each pressing portion.

[0012] In the third direction in which the first pressing portion and the second pressing portion are aligned, at least a portion of the slit may be positioned at the same position as the fixed portion. Displacement is less likely to be transmitted between the first pressing portion and the second pressing portion near the fixed portion. Therefore, by bringing the slit and the fixed portion closer together, the number of paths through which displacement is transmitted between the first pressing portion and the second pressing portion can be further reduced.

[0013] In a third direction in which the first pressing portion and the second pressing portion are aligned, at least a portion of the slit may be positioned at the same position as the gap between the first component and the second component. Because a pressing portion cannot be provided at the position of the gap, by positioning the slit near the gap, sufficient space can be secured for arranging the pressing portion. This allows each component to be supported in a balanced manner by each pressing portion. [Effects of the Invention]

[0014] According to the present disclosure, it is possible to provide a component mounting structure that can suppress an increase in size of a product and can sufficiently press multiple components with a small number of components.

[0015] A component mounting structure according to one embodiment of the present disclosure includes a housing, a first component arranged in the housing, a second component adjacent to the first component, and a pressing member that presses the first component and the second component toward the housing, the pressing member including a support portion fixed to the housing, a step portion extending in a first direction from the support portion toward the opposite side of the housing, and a first pressing portion that presses the first component and a second pressing portion that presses the second component, the first pressing portion extending from an end side of the step portion opposite the housing in a second direction intersecting the first direction, the first pressing portion pressing the first component, and the second pressing portion pressing the second component, a slit being provided between the first pressing portion and the second pressing portion, and the slit extending in the first direction beyond the center position of the step portion toward the support portion.

[0016] In a component mounting structure according to one embodiment of the present disclosure, the pressing member includes a support portion fixed to the housing, a stepped portion extending in a first direction from the support portion toward the opposite side of the housing, and a first pressing portion that presses the first component and a second pressing portion that presses the second component, extending from an end of the stepped portion opposite the housing in a second direction intersecting the first direction. This allows the pressing member to support the first component and the second component with a single member. A slit is provided between the first pressing portion and the second pressing portion, and the slit extends from the center of the stepped portion toward the support portion in the first direction. Therefore, the slit, which reaches from the center of the stepped portion toward the support portion, interrupts the transmission path of displacement between the first pressing portion and the second pressing portion. Therefore, the slit prevents displacement generated by one pressing portion pressing one component from interfering with the other pressing portion. Therefore, sufficient pressing force can be obtained at each pressing portion without increasing the distance between the first and second components or dividing the pressing member. As a result, the product size can be prevented from increasing and multiple components can be pressed sufficiently with a small number of components. [Brief explanation of the drawings]

[0018] Referring to FIG. 1, a power supply device 1 including a component mounting structure 100 according to an embodiment of the present disclosure will be described. FIG. 1 is a side view showing the power supply device 1 including the component mounting structure 100 according to an embodiment of the present disclosure. As shown in FIG. 1, the power supply device 1 includes a base plate 2 (housing), a substrate 3, and a lid 4. The power supply device 1 is constructed by assembling the lid 4 to the base plate 2 that houses the substrate 3. A die-cast alloy or the like is used as a material for the base plate 2. The power supply device 1 is a unit that includes, for example, an AC / DC power supply, a DC / DC converter, and the like. The component mounting structure 100 is provided within the power supply device 1. However, the overall shape of the power supply device 1 is not limited to that shown in FIG. 1. Furthermore, the position of the component mounting structure 100 within the power supply device 1 is not particularly limited.

[0019] A component mounting structure 100 according to an embodiment of the present disclosure will be described with reference to FIGS. 2 to 4. FIGS. 2 and 3 are perspective views of the component mounting structure 100 according to this embodiment of the present disclosure. FIG. 4 is a plan view of the component mounting structure 100. In the drawings, the X-axis and Y-axis directions are defined relative to the direction in which the bottom surface of the base plate 2 and the substrate 3 (see FIG. 1) extend. In the drawings, the Z-axis direction is defined relative to the thickness direction of the bottom surface of the base plate 2 and the substrate 3. In this specification, the upper side is defined as the positive side in the Z-axis direction, and the lower side is defined as the negative side in the Z-axis direction. For ease of explanation, terms such as "upper" and "lower" may be used in this specification, but these terms do not limit the orientation of the power supply device 1 or the component mounting structure 100 during use. As shown in FIGS. 2 to 4, the component mounting structure 100 includes a base plate 2, a substrate 3, a first component 10A, a second component 10B, and a pressing member 20.

[0020] The first component 10A and the second component 10B are components arranged on the base plate 2. The first component 10A is mounted on the substrate 3. In this embodiment, the components 10A and 10B are exemplified by cores made of a magnetic material and provided for a coil. The components 10A and 10B are configured as rectangular parallelepiped members with their longitudinal direction in the X-axis direction. The components 10A and 10B have top surfaces 10Aa and 10Ba parallel to the XY plane at positions higher than the bottom surface of the base plate 2 and the substrate 3.

[0021] Components 10A and 10B are arranged adjacent to each other in the X-axis direction. Second component 10B is arranged adjacent to first component 10A on the negative side of the X-axis direction. An end face 10Ab of first component 10A on the negative side in the X-axis direction and an end face 10Bb of second component 10B on the positive side in the X-axis direction face each other while being spaced apart in the X-axis direction. A gap GP is formed between first component 10A and second component 10B (see FIG. 4). Note that base plate 2 is provided with ribs for positioning components 10A and 10B, bosses for fastening substrate 3 with bolts, and the like. Movement of components 10A and 10B in the X-axis and Y-axis directions is restricted not only by being pressed by pressing member 20 but also by the ribs of base plate 2.

[0022] The pressing member 20 is a member that presses the first component 10A and the second component 10B downward (toward the housing). The pressing member 20 includes a support portion 21, a step portion 22, an edge portion 36, a first pressing portion 23A, and a second pressing portion 23B. In this embodiment, the pressing member 20 is a member in which these components 21, 22, 23A, and 23B are integrally formed by cutting and bending a single piece of metal sheet. Therefore, the pressing member 20 is configured as a single metal sheet (see FIG. 6). However, the pressing member 20 does not necessarily have to be configured by bending a single piece of metal sheet alone, and may be configured by joining multiple metal sheets together by a joining method such as welding. In this embodiment, the pressing member 20 may be disposed on the negative side of the components 10A and 10B in the Y-axis direction.

[0023] The support portion 21 supports the step portion 22 and the pressing portions 23A and 23B and is fixed to the base plate 2. The support portion 21 has a flat plate shape parallel to the XY plane and extends in the X-axis direction. The step portion 22 is a portion that rises upward from the support portion 21 (the side opposite the housing) and has a flat plate shape that rises at an angle with respect to the XY plane. The positive ends of the support portion 21 and the step portion 22 in the X-axis direction are located near the positive end of the first component 10A in the X-axis direction. The negative ends of the support portion 21 and the step portion 22 in the X-axis direction are located near the negative end of the second component 10B in the X-axis direction. The edge portion 36 extends from the upper end of the step portion 22 (the side opposite the housing) toward the components 10A and 10B. The configuration of the edge portion 36 will be described later.

[0024] The support part 21 is fixed to the base plate 2 via fixing parts 26A, 26B, and 26C. The fixing part 26A is provided near the end of the support part 21 on the positive side in the X-axis direction. The fixing part 26B is provided near the end of the support part 21 on the negative side in the X-axis direction. The fixing part 26C is provided near the center position of the support part 21 in the X-axis direction. The fixing parts 26A, 26B, and 26C are configured by a fastening structure using a bolt 27 and a boss 28 (see FIG. 3) provided on the base plate 2. Furthermore, each of the fixing parts 26A, 26B, and 26C has a through-hole 29 in the support part 21 (see FIG. 6) for inserting a shaft part 27a of the bolt 27 (see FIG. 5).

[0025] The first pressing portion 23A protrudes from the edge 36 toward the first component 10A and presses the first component 10A. The second pressing portion 23B protrudes from the edge 36 toward the second component 10B and presses the second component 10B. The first pressing portion 23A and the second pressing portion 23B extend from the edge 36 on the positive side of the Y-axis direction, slanting downward. The first pressing portion 23A and the second pressing portion 23B press the top surface 10Aa of the first component 10A and the top surface 10Ba of the second component 10B downward.

[0026] In this embodiment, the pressing member 20 has two first pressing portions 23A and two second pressing portions 23B. The two first pressing portions 23A are arranged at positions spaced apart from each other in the X-axis direction. The two first pressing portions 23A press the first component 10A near its end on the positive side in the X-axis direction and its end on the negative side in the X-axis direction. The two second pressing portions 23B are arranged at positions spaced apart from each other in the X-axis direction. The two second pressing portions 23B press the second component 10B near its end on the positive side in the X-axis direction and its end on the negative side in the X-axis direction. The first pressing portion 23A on the negative side in the X-axis direction and the second pressing portion 23B on the positive side in the X-axis direction are adjacent to each other and spaced apart from each other in the X-axis direction. A slit 50 is provided between the first pressing portion 23A and the second pressing portion 23B. In this embodiment, a slit 50 is provided between the first pressing portion 23A on the negative side in the X-axis direction and the second pressing portion 23B on the positive side in the X-axis direction.

[0027] Next, the configuration of the pressing member 20 will be described in more detail with reference to FIGS. 5 and 6. FIG. 5 is a cross-sectional view taken along line VV in FIG. 4. FIG. 6 is a perspective view of the pressing member 20. Note that while FIG. 5 shows the fixed portion 26C and the first pressing portion 23A on the negative side in the X-axis direction, the other fixed portions 26A, 26B and the other pressing portions 23A, 23B have the same configuration. As shown in FIG. 5, the support portion 21 is disposed below the top surface 10Aa of the first component 10A. The support portion 21 is disposed at a position spaced further toward the negative side in the Y-axis direction than the side surface 10Ac on the negative side in the Y-axis direction of the first component 10A. A step portion 22 extends from the end of the support portion 21 on the positive side in the Y-axis direction along a first direction D1. The first direction D1 is inclined with respect to the Z-axis direction so as to move upward toward the positive side in the Y-axis direction. However, the inclination angle of the first direction D1 with respect to the Z-axis direction is not particularly limited, and may be parallel to the Z-axis direction. The boundary 31 between the support portion 21 and the step portion 22 is curved so that the lower side is on the outer periphery side by adding a corner R. The radius of curvature of the boundary 31 is not particularly limited, and can be changed as appropriate. The curved boundary 31 is located at an intermediate position between the support portion 21 and the step portion 22, and is a region that does not belong to either the support portion 21 or the step portion 22.

[0028] The step portion 22 extends above the upper surface 10Aa of the first component 10A. The first pressing portion 23A has a first portion 32 and a second portion 33. The edge portion 36 extends from the upper end of the step portion 22 in a second direction D2 intersecting with the first direction D1. Furthermore, the first portion 32 protrudes from the edge portion 36 in the second direction D2. The second direction D2 is inclined with respect to the Z-axis direction so as to move downward toward the positive side of the Y-axis direction. However, the inclination angle of the second direction D2 with respect to the Z-axis direction is not particularly limited. The boundary portion 34 between the edge portion 36 and the first portion 32 is curved by a corner R so that the upper side is on the outer periphery side. The radius of curvature of the boundary portion 34 is not particularly limited and can be changed as appropriate. The curved boundary portion 34 is located at an intermediate position between the step portion 22 and the edge portion 36, and is an area that does not belong to either the step portion 22 or the edge portion 36.

[0029] The second portion 33 is a curved portion formed by adding a rounded corner to the lower end of the first portion 32, so that the lower side is on the outer periphery. The lower surface 33a of the second portion 33 is the contact surface that comes into contact with the upper surface 10Aa of the first component 10A. When the pressing member 20 is fixed by the fixing portions 26A, 26B, and 26C without the first component 10A being present on the base plate 2, the lower surface 33a of the second portion 33 is located at a position lower than the position of the upper surface 10Aa shown in FIG. 5. Therefore, when the pressing member 20 is fixed by the fixing portions 26A, 26B, and 26C with the first component 10A being present on the base plate 2, the step portion 22 and the first pressing portion 23A are elastically deformed. This allows the first pressing portion 23A to apply a downward pressing force to the first component 10A.

[0030] As shown in FIG. 6, in regions 40A, 40B, and 40C of the pressing member 20 in the X-axis direction where the pressing portions 23A and 23B are not provided, the first portion 32 is cut away to form an edge portion 36. The edge portion 36 extends along the second direction D2. The distance of the edge portion 36 from the boundary portion 34 toward the positive side in the Y-axis direction is shorter than that of the first portion 32. The region 40A is a region between two first pressing portions 23A. The region 40B is a region between two second pressing portions 23B. The region 40C is a region between the first pressing portion 23A on the negative side in the X-axis direction and the second pressing portion 23B on the positive side in the X-axis direction.

[0031] Next, the slit 50 will be described in detail with reference to FIGS. 4 and 6. As shown in FIG. 6, the slit 50 extends from a location corresponding to the edge 36 toward the negative side in the Y-axis direction in the region 40C between the first pressing portion 23A on the negative side in the X-axis direction and the second pressing portion 23B on the positive side in the X-axis direction. The slit 50 has a pair of side surfaces 50a and a bottom surface 50b, which is an end portion on the negative side in the Y-axis direction. The pair of side surfaces 50a extend parallel to the Y-axis direction (see FIG. 4), but the shape is not particularly limited, and the bottom surface 50b may extend so as to be inclined toward the Y-axis direction. The bottom surface 50b is curved in a semicircular shape at the end portion on the negative side in the Y-axis negative direction of the pair of side surfaces 50a, but the shape is not particularly limited, and the bottom surface 50b may have a substantially linear shape extending in the X-axis direction.

[0032] In this embodiment, the slit 50 reaches the support portion 21. Here, at least a portion of the bottom surface 50b of the slit 50 is disposed in the support portion 21. The bottom surface 50b is disposed in a region near the boundary portion 31 of the support portion 21, but may also be disposed on the negative side in the Y-axis direction. The slit 50 reaching an arbitrary position means that at least a portion of the slit 50 is present at an arbitrary position.

[0033] The slit 50 only needs to reach the step portion 22. That is, it is sufficient that at least a portion of the bottom surface 50b is located somewhere on the negative side of the boundary portion 34 in the Y-axis direction. Note that a configuration in which the slit 50 is formed only in the edge portion 36, or a configuration in which the slit 50 is formed only in the edge portion 36 and the boundary portion 34, does not correspond to a configuration in which the slit 50 reaches the step portion 22. Therefore, a structure in which the first portion 32 is cut out in the regions 40A and 40B does not correspond to a slit 50 that reaches the step portion 22. The slit 50 may reach a position closer to the support portion 21 (to the negative side in the Y-axis direction) than the center position CL of the step portion 22 in the first direction D1. Alternatively, the slit 50 may reach the boundary portion 31 between the step portion 22 and the support portion 21.

[0034] The step portion 22 is a portion that forms a step between the support portion 21 and the edge portion 36. For example, in the aforementioned Patent Document 1, a side wall portion extends upward from the portion corresponding to the support portion 21, and a pressing portion protrudes from the upper end of the side wall portion. In this configuration, the edge portion 36 does not exist in any portion other than the pressing portion, and therefore the step portion 22 does not exist. Therefore, there is no slit that reaches the step portion 22.

[0035] As shown in FIG. 4, in the X-axis direction (third direction) in which the first pressing portion 23A and the second pressing portion 23B are aligned, at least a portion of the slit 50 may be positioned at the same position as the fixed portion 26C. The state in which at least a portion of the slit 50 is positioned at the same position as the fixed portion 26C in the X-axis direction means that, when a pair of reference lines SL parallel to the Y-axis direction are set for both ends (here, both side surfaces 50a) of the slit 50 in the X-axis direction, at least a portion of the fixed portion 26C is located between the pair of reference lines SL. In this embodiment, at least a portion of the slit 50 is positioned at the same position as the bolt 27 of the fixed portion 26C. Furthermore, at least a portion of the slit 50 is positioned at the same position as the through-hole 29 of the support portion 21 (see FIG. 6). In the X-axis direction, at least a portion of the slit 50 is positioned at the same position as the gap GP between the first component 10A and the second component 10B.

[0036] The width of the slit 50 (the size in the X-axis direction) is not particularly limited. The lower limit of the width of the slit 50 is set by the lower limit of the size of the processing tool that can process the slit 50. The upper limit of the width of the slit 50 is set by the distance between the first pressing portion 23A and the second pressing portion 23B. The range of the width of the slit is not particularly limited.

[0037] Next, the functions and effects of the component mounting structure 100 according to this embodiment will be described.

[0038] In the component mounting structure 100 according to this embodiment, the pressing member 20 includes a support portion 21 fixed to the base plate 2, a step portion 22 extending in a first direction D1 from the support portion 21 toward the opposite side of the base plate 2, an edge portion 36 extending from the end of the step portion 22 opposite the base plate 2 in a second direction D2 intersecting the first direction D1, and a first pressing portion 23A protruding from the edge portion 36 and pressing the first component 10A and a second pressing portion 23B protruding from the edge portion 36 and pressing the second component 10B. This allows the pressing member 20 to support the first component 10A and the second component 10B with a single member. A slit 50 is provided between the first pressing portion 23A and the second pressing portion 23B, and the slit 50 reaches at least the step portion 22. Therefore, the path of displacement transmission between first pressing portion 23A and second pressing portion 23B is divided by slit 50, which reaches step portion 22. Therefore, slit 50 can prevent displacement generated when one pressing portion presses one component from interfering with the other pressing portion. Therefore, sufficient pressing force can be obtained from each pressing portion 23A, 23B without increasing the distance between first component 10A and second component 10B or dividing the pressing member. As a result, the product can be prevented from becoming large, and multiple components can be sufficiently pressed with a small number of components.

[0039] The slit 50 may extend in the first direction D1 from the center of the stepped portion 22 toward the support portion 21. In this case, half of the area of ​​the stepped portion 22 in the first direction D1 is divided by the slit 50. This further reduces the path of displacement transmission between the first pressing portion 23A and the second pressing portion 23B.

[0040] The slit 50 may reach the boundary 31 between the step portion 22 and the support portion 21. In this case, the entire area of ​​the step portion 22 in the first direction D1 is divided by the slit 50. This makes it possible to further reduce the path of displacement transmission between the first pressing portion 23A and the second pressing portion 23B.

[0041] The slit 50 may reach the support portion 21. In this case, the entire area of ​​the step portion 22 in the first direction D1 and the boundary portion 31 are divided by the slit 50. This makes it possible to further reduce the transmission path of displacement between the first pressing portion 23A and the second pressing portion 23B.

[0042] The support portion 21 may be fixed to the base plate 2 via the fixing portions 26A, 26B, and 26C. In this case, elastic deformation can be easily generated in the pressing portions 23A and 23B.

[0043] In the X-axis direction (third direction) in which the first pressing portion 23A and the second pressing portion 23B are aligned, at least a portion of the slit 50 may be disposed in the same position as the fixed portion 26C. Displacement is less likely to be transmitted between the first pressing portion 23A and the second pressing portion 23B near the fixed portion 26C. Therefore, by bringing the slit 50 and the fixed portion 26C closer to each other, the transmission path of displacement between the first pressing portion 23A and the second pressing portion 23B can be further reduced.

[0044] In the X-axis direction in which the first pressing portion 23A and the second pressing portion 23B are aligned, at least a portion of the slit 50 may be positioned at the same position as the gap GP between the first component 10A and the second component 10B. Because a pressing portion cannot be provided at the position of the gap GP, by positioning the slit 50 near the gap GP, it is possible to ensure sufficient space for placing a pressing portion. This allows the components 10A, 10B to be supported in a balanced manner by the pressing portions 23A, 23B.

[0045] The present disclosure is not limited to the above-described embodiments.

[0046] The size, arrangement, and number of components are not limited to those in the above-described embodiment and can be changed as appropriate. Also, in the above-described embodiment, components are arranged only on one side in the Y-axis direction from the support portion 21, but components may be arranged on both sides. In this case, pressing portions may be provided on both sides in the Y-axis direction from the support portion 21. Also, the type of components is not particularly limited, and components other than cores may be used.

[0047] The pressing member 20 shown in FIG. 7(a) may be employed. Unlike the above-described embodiment, the pressing member 20 has an edge 136 between the pressing portions 23A, 23A, which is provided at the position of the step portion 22 and does not correspond to an edge extending in the second direction. The same applies to the edge 136 between the pressing portions 23B, 23B. In this case, the slit 50 may extend further toward the support portion 21 than the center position of the step portion 22 in the first direction D1. Alternatively, the pressing member 20 shown in FIG. 7(b) may be employed. This pressing member 20 has only one second pressing portion 23B on the second pressing portion 23B side of the slit 50. The first pressing portion 23A side may also have only one first pressing portion 23A.

[0048] Each pressing member 20 includes a support portion 21 fixed to the base plate 2, a step portion 22 extending from the support portion 21 in a first direction D1 toward the opposite side of the housing, and a first pressing portion 23A that presses the first component 10A and a second pressing portion 23B that presses the second component 10B, extending from an end of the step portion 22 opposite the base plate 2 in a second direction D2 intersecting the first direction D1. This allows the pressing member 20 to support the first component 10A and the second component 10B with a single member. A slit 50 is provided between the first pressing portion 23A and the second pressing portion 23B, and the slit 50 reaches from the center of the step portion 22 toward the support portion 21 in the first direction D1. Therefore, the path of displacement transmission between first pressing portion 23A and second pressing portion 23B is divided by slit 50, which reaches from the center position of step portion 22 toward support portion 21. Therefore, slit 50 can prevent displacement caused by one pressing portion pressing one component from interfering with the other pressing portion. Therefore, sufficient pressing force can be obtained at each pressing portion 23A, 23B without increasing the distance between first component 10A and second component 10B or dividing pressing member 20. As a result, the product can be prevented from becoming large in size, and multiple components can be sufficiently pressed with a small number of components.

[0049] As in the pressing member 120 shown in FIG. 8(a), the first pressing portion 23A and the second pressing portion 23B may extend in different directions rather than parallel to each other. Each pressing portion 23A, 23B has a V-shape in plan view. In this case, the slit 50 may extend further toward the support portion 21 than the center position of the step portion 22 in the first direction D1. Furthermore, as in the pressing member 220 shown in FIG. 8(b), the pressing portion 23 may extend not only to one side of the support portion 21 but also to the opposite side. A slit 50 is formed between each pressing portion 23.
