Conventionally, as a fixed structure, the one described in Patent Document 1 is known. This fixing structure fixes electronic components mounted on a mounting surface of a structure by pressing them with a fixture.

The plurality of arm parts are configured to be symmetrical, and the fixing plate part is screwed to the structure at the center position.

JP2014-147210A

In the above-described fixing structure, the fixing positions of the plurality of arms and the fixing plate portion are configured to be symmetrical. Therefore, each arm portion of the fixture can press the electronic component with substantially equal pressing force. Here, in the fixed structure, if the fixed position of the fixed plate part and the arrangement of the arm parts are unbalanced due to the positional relationship with the surrounding parts of the structure, the pressing force of each arm part will be balanced. becomes worse. Therefore, it is necessary to maintain a well-balanced arrangement of each arm so that the pressing force exerted by each arm is as designed. In this case, priority must be given to arranging each arm portion in a well-balanced manner, which makes it difficult to freely arrange parts around the electronic parts, resulting in a problem that the structure of the structure is subject to restrictions.

An object of the present invention is to provide a fixing structure and a fixture that can reduce restrictions on the structure of a structure in which electronic components are mounted.

A fixing structure according to the present invention is a fixing structure that presses and fixes an electronic component mounted on a mounting surface of a structure with a fixing tool, and the fixing tool includes a fixing plate part fixed to the structure and a mounting surface. In a plan view of the surface, at least a first arm part and a second arm part extend from the fixing plate part toward the electronic component, and the first arm part and the second arm part extend from the fixing plate part. At the edge, there is a rising part that bends toward the opposite side of the structure and extends away from the structure, and a rising part that bends toward the structure at the tip of the rising part and extends in a direction that approaches the structure. an extension part that extends and presses the electronic component at the support part on the distal end side, and in plan view, the distance between the support part of the first arm part and the fixed plate part is equal to that of the second arm part The height of the rising part of the first arm part from the mounting surface is higher than the height of the rising part of the second arm part from the mounting surface. .

In the fixing structure according to the present invention, the first arm part and the second arm part are bent toward the opposite side of the structure at the edge of the fixing plate part, and the rising part extends in a direction away from the structure. and an extending portion that is bent toward the structure at the tip side of the rising portion, extends in a direction approaching the structure, and presses the electronic component at the support portion on the tip side. Therefore, the first arm section and the second arm section each press the electronic component with the support section on the tip side of the extension section. Here, in plan view, the distance between the support part of the first arm part and the fixed plate part is shorter than the distance between the support part of the second arm part and the fixed plate part. For example, if the first arm part and the second arm part are configured to extend linearly from the fixing plate part to the electronic component, the total length of the second arm part is longer than the total length of the first arm part. Because of the length, the pressing force of the second arm tends to be smaller than the pressing force of the first arm. In contrast, in the fixing structure according to the present invention, the height of the rising portion of the first arm portion is higher than the height of the rising portion of the second arm portion. In this case, since the entire length of the first arm can be increased, the pressing force of the first arm can be suppressed. That is, by adjusting the height of the rising portion of each arm, it is possible to adjust the pressing force of each arm. In this case, even if the configuration of each arm in a plan view corresponds to the arrangement of components around the electronic component, a desired pressing force can be obtained by adjusting the height of the rising portion. As described above, restrictions on the structure of the structure in which electronic components are mounted can be reduced.

The width of the second arm portion may be wider than the width of the first arm portion. In this case, the pressing force of the second arm portion can be increased.

The rising portion may rise perpendicularly to the fixed plate portion. In this case, it is possible to simplify the model used to calculate the pressing force of each arm, thereby improving the ease of design.

A fixture according to the present invention is a fixture that presses and fixes an electronic component mounted on a mounting surface of a structure, and includes a fixing plate portion fixed to the structure and a planar view of the fixing plate portion. At least a first arm part and a second arm part extending from the fixing plate part to the outside with respect to the fixing plate part, and when the first direction is the direction perpendicular to the main surface of the fixing plate part, the first The arm portion and the second arm portion include a rising portion bent toward one side in the first direction at the edge of the fixing plate portion and extending to the one side, and a rising portion on the tip side of the rising portion. an extension part that is bent toward the other side in the first direction, extends to the other side, and presses the electronic component at the support part on the distal end side, and in a plan view, the support part of the first arm part; and the fixed plate part is shorter than the distance between the support part of the second arm part and the fixed plate part, and the height of the rising part of the first arm part from the fixed plate part is: It is higher than the height of the rising part of the second arm part from the fixed plate part.

With the fixture according to the present invention, it is possible to obtain the same functions and effects as the above-mentioned fixing structure.

According to the present invention, it is possible to provide a fixing structure and a fixture that can reduce restrictions on the structure of a structure in which electronic components are mounted.

FIG. 1 is a perspective view showing a fixing structure according to an embodiment of the present invention. FIG. 2 is a plan view of the fixing structure shown in FIG. 1; (a) is a side view showing the first arm part, and (b) is a side view showing the second arm part. FIG. 3 is a side view of the fixing structure viewed from the tip side of the arm portion. It is a top view which shows the fixing structure based on a modification.

With reference to FIG. 1, a fixing structure and a fixture according to an embodiment of the present invention will be described. FIG. 1 is a perspective view showing a fixing structure 100 according to an embodiment of the present invention. FIG. 2 is a plan view of the fixing structure shown in FIG. 1. FIG. 3(a) is a side view showing the first arm portion 20. FIG. FIG. 3(b) is a side view showing the second arm portion 30. FIG.

As shown in FIG. 1, the fixing structure 100 is a structure in which an electronic component 1 mounted on a mounting surface 50a of a substrate 50 (structure) is pressed by a fixture 2 and fixed. The mounting surface 50a extends in a planar manner on one side of the substrate 50. Note that the X-axis is set in a direction parallel to the mounting surface 50a and the main surface 10a of the fixing plate section 10, which will be described later, and the Set the Y axis, and set the Z axis in a direction perpendicular to the X and Y axes. The direction from the inside of the board 50 toward the mounting surface 50a is defined as the positive side in the Z-axis direction. The Z-axis direction is a direction perpendicular to the main surface 10a of the fixed plate part 10, and corresponds to the "first direction" in the claims. Further, the positive side in the Z-axis direction corresponds to "one side in the first direction" in the claims, and the negative side in the Z-axis direction corresponds to "the other side in the first direction" in the claims.

The electronic component 1 is mounted on the mounting surface 50a of the board 50. Here, as the electronic component 1, a rectangular parallelepiped component having a longitudinal direction in the X-axis direction is employed. The electronic component 1 has an upper surface 1a that extends parallel to the XY plane at a position spaced apart from the mounting surface 50a on the positive side in the Z-axis direction. This upper surface 1a becomes a pressed surface that is pressed by the fixture 2. The electronic component 1 has a mounted surface 1b that faces the mounting surface 50a in the Z-axis direction and is in close proximity to or in contact with the mounting surface 50a. Note that FIG. 4 is a side view of the fixing structure 100 viewed from the distal end side of the arm portions 20, 30. However, FIG. 4 shows the state when the electronic component 1 is removed from the fixing structure 100. That is, FIG. 4 shows a state before the arm parts 20, 30 are elastically deformed. In FIG. 4, the upper surface 1a is shown by a virtual line.

The electronic component 1 may be directly bonded to the mounting surface 50a of the board 50. In this case, the lower surface of the substrate 50 on the side opposite to the mounting surface 50a may be in contact with a casing (structure) such as a base plate with an insulator such as an insulating sheet interposed therebetween. In this case, the heat of the pressed electronic component 1 is radiated through the substrate 50, the insulating sheet, and the base plate. Note that the electronic component 1 may be a transformer such as a core component. For example, if the coil is a sheet coil configured on the board 50, two core pieces are mounted with the board 50 in between. In this case, the upper core corresponds to the "electronic component 1", and the upper surface of the bridge portion of the core corresponds to the "upper surface 1a" to be pressed. The upper surface of the core is pressed, and the lower surface of the bridge portion of the lower core comes into contact with a casing (structure) such as a base plate, and radiates heat from the core to the base plate. Even when the coil is not a sheet coil configured on the substrate 50, the configuration is the same as described above, except that the core does not sandwich the substrate 50.

A boss 51 is provided on the mounting surface 50a at a position spaced apart from the electronic component 1 toward the negative side in the Y-axis direction. The boss 51 is a cylindrical protrusion that protrudes from the mounting surface 50a toward the positive side in the Z-axis direction. The boss 51 is arranged in the X-axis direction at a position corresponding to the end of the electronic component 1 in the X-axis direction. This boss 51 is a member for fixing the fixture 2 and is a part of the structure.

The boss 51 extends from a base plate provided on the lower surface side of the substrate 50, passing through a through hole formed in the substrate 50, to a position higher than the mounting surface 50a. Note that the configuration of the structure to which the fixture 2 is fixed is not particularly limited. For example, if there is a fixing part that fixes the substrate 50 to the base plate, the fixture 2 may be fixed by using the fixing part together. For example, when fixing the substrate 50 and fixture 2 to the boss of the base plate, the upper surface of the boss supports the lower surface of the substrate 50 at the position of the through hole. Then, the fixture 2 is set in the through hole of the board 50, and the fixture 2 and the board 50 are fastened together to the boss. Further, the structure for receiving the bolt 52 for fixing the fixture 2 does not need to be a boss, and may be, for example, the upper end surface of the side wall of the base plate.

The fixture 2 is a metal fixture for pressing the electronic component 1 and fixing the electronic component 1 to the board 50. The fixture 2 presses the electronic component 1 while being fixed to the boss 51, which is a structure. The fixture 2 is fixed to the boss 51 with a bolt 52. The fixture 2 includes a fixing plate section 10, a first arm section 20, and a second arm section 30. The fixture 2 is formed by processing a metal plate.

The fixing plate part 10 is a part that is fixed to a boss 51 which is a structure. The fixed plate part 10 is a plate-shaped member that extends parallel to the XY plane. The fixing plate section 10 is placed on the upper surface of the boss 51. Further, the bolt 52 is inserted into the fixing plate portion 10 from the positive side to the negative side in the Z-axis direction. Thereby, the fixing plate part 10 is fixed by being sandwiched between the upper surface of the boss 51 and the head of the bolt 52. Note that the fixing structure formed by the boss 51 and the bolt 52 is referred to as a fixing part 55.

As shown in FIG. 2, the fixing plate section 10 includes a main body section 11, a connecting section 12, a connecting section 13, and a positioning section 14. The main body portion 11 is a portion fixed by a boss 51 and a bolt 52. Note that the center of the bolt 52 is defined as the reference point CP of the fixing portion 55 of the fixing plate portion 10. At this time, the reference point CP is located at a position on the positive side of the main body 11 in the X-axis direction. In this way, the reference point CP of the fixing part 55 is arranged at a position closer to the positive side in the X-axis direction when the fixing tool 2 is viewed as a whole.

The connecting portion 12 is a portion connected to the first arm portion 20. The connecting portion 12 is a portion that protrudes from the end of the main body portion 11 on the positive side in the Y-axis direction toward the positive side in the Y-axis direction. The connecting portion 12 is a portion connected to the second arm portion 30. The connecting portion 13 is a portion that protrudes from the negative end of the main body portion 11 in the X-axis direction toward the negative side in the X-axis direction. The connecting portion 13 is inclined toward the positive side in the Y-axis direction as it goes toward the negative side in the X-axis direction. The positioning part 14 is a part for positioning the fixture 2 in the rotational direction. The positioning portion 14 protrudes from the end of the main body portion 11 on the positive side in the X-axis direction toward the positive side in the Y-axis direction, and has a positioning hole 14a. A protrusion (not shown) extending from the mounting surface 50a toward the positive side in the Z-axis direction is inserted into the positioning hole 14a. As a result, rotation of the fixture 2 around the reference point CP is suppressed.

As shown in FIGS. 1 and 2, the first arm portion 20 extends from the fixed plate portion 10 toward the electronic component 1 in a plan view of the mounting surface 50a (the state shown in FIG. 2). That is, the first arm portion 20 extends from the fixed plate portion 10 to the outside with respect to the fixed plate portion 10 in a plan view of the fixed plate portion 10 . Here, the outside with respect to the fixed plate part 10 refers to the direction away from the fixed plate part 10 with respect to the outer edge of the fixed plate part 10 in a direction parallel to the XY plane. The first arm portion 20 extends linearly from the connecting portion 12 of the fixed plate portion 10 toward the positive side of the Y-axis direction in parallel to the Y-axis direction. The first arm portion 20 presses a portion of the upper surface 1a of the electronic component 1 on the positive end side of the center position in the X-axis direction. The first arm portion 20 includes a rising portion 21, an extending portion 22, and a bent portion 23.

The second arm portion 30 extends from the fixed plate portion 10 toward the electronic component 1 in a plan view of the mounting surface 50a (the state shown in FIG. 2). That is, the second arm portion 30 extends from the fixed plate portion 10 to the outside with respect to the fixed plate portion 10 in a plan view of the fixed plate portion 10. The second arm portion 30 extends linearly from the connecting portion 13 of the fixed plate portion 10 so as to be inclined toward the negative side in the X-axis direction and toward the positive side in the Y-axis direction. The second arm portion 30 presses a portion of the upper surface 1a of the electronic component 1 on the negative end side of the center position in the X-axis direction. The second arm portion 30 includes a rising portion 31, an extending portion 32, and a bent portion 33.

The rising portions 21 and 31 are bent toward the positive side in the Z-axis direction at the edge of the fixed plate portion 10. The rising portions 21 and 31 rise from the connecting portions 12 and 13 of the fixed plate portion 10 along the Z-axis direction. Note that the positive side in the Z-axis direction on which the rising portions 21 and 31 rise is defined as the "upper side", and the terms "upper" and "lower" are sometimes used. The rising parts 21 and 31 stand up perpendicularly to the fixed plate part 10. That is, the rising portions 21 and 31 are bent toward the opposite side of the substrate 50 at the edge of the fixed plate portion 10 and extend in a direction away from the substrate 50 (here, an upward direction).

The extending portions 22 and 32 are bent downward at the upper ends of the rising portions 21 and 31 (tips of the rising portions) and extend toward the electronic component 1 . The extension parts 22 and 32 press the electronic component 1 at the support parts P1 and P2 (see FIG. 2) on the tip side (lower end side). The bent portions 23 and 33 are formed by bending diagonally upward at the lower end portions of the extending portions 22 and 32. That is, the extending portions 22 and 32 are bent toward the substrate 50 at the tips of the rising portions 21 and 31, and extend in a direction approaching the substrate 50 (in this case, a downward direction). Thereby, the arm parts 20, 30 press the upper surface 1a of the electronic component 1 at the corner between the extending parts 22, 32 and the bent parts 23, 33. In addition, in FIG. 2, support parts P1 and P2 are set at the center of the corner.

Next, the difference in structure between the first arm section 20 and the second arm section 30 will be explained with reference to FIGS. 2 to 4.

As shown in FIG. 2, in plan view, the distance L1 between the support part P1 of the first arm part 20 and the fixed plate part 10 is the same as the distance L1 between the support part P2 of the second arm part 30 and the fixed plate part 10. shorter than the distance between. The base point of the distance L1 on the fixed plate part 10 side is set at the corner between the lower end of the rising part 21 and the connecting part 12 of the fixed plate part 10. The distance L1 is a distance in the extending direction of the first arm portion 20 (here, a direction parallel to the Y-axis direction) in a plan view. The base point of the distance L2 on the fixed plate part 10 side is set at the corner between the lower end of the rising part 31 and the connecting part 13 of the fixed plate part 10. The distance L2 is a distance in the extending direction of the second arm portion 30 (here, a direction inclined with respect to the Y-axis direction and the X-axis direction) in plan view. It is assumed that the dimensional difference between the distance L1 and the distance L2 is greater than a minute dimensional difference due to manufacturing errors, errors during deformation, or the like. For example, the ratio of the dimensional difference between distance L2 and distance L1 to distance L2 may be 5% or more, although it is not limited to this ratio.

In addition, in plan view, the distance R1 between the reference point CP of the fixing part 55 of the fixing plate part 10 and the support part P1 of the first arm part 20 is equal to It is closer than the distance R2 to P2. As mentioned above, the reference point CP is located near the positive end of the fixing plate 10 in the X-axis direction, and the first arm 20 is also located near the positive end of the fixing plate 10 in the X-axis direction. It is located near the end. On the other hand, the second arm portion 30 extends further toward the negative side in the X-axis direction from near the end of the fixed plate portion 10 on the negative side in the X-axis direction. Further, the positions in the Y-axis direction of the support portion P1 of the first arm portion 20 and the support portion P2 of the second arm portion 30 are approximately equal. As described above, the support part P1 is arranged closer to the reference point CP than the support part P2. In addition, the point that the dimensional difference between distance R1 and distance R2 is more than a minute dimensional difference due to manufacturing error or error during deformation, and the ratio thereof is the same as distances L1 and L2. be.

The width W2 of the second arm portion 30 is wider than the width W1 of the first arm portion 20. The width of the arm portions 20, 30 is a dimension in a direction perpendicular to the extending direction of the arm portions 20, 30 in plan view. The width W2 of the rising portion 31 is wider than the width W1 of the rising portion 21. Note that the width of the connecting portion 13 is set to be the same as the width W2 of the rising portion 31. The width of the connecting portion 12 is set to be the same as the width W1 of the rising portion 21. The width W2 of the second arm portion 30 tapers in the extension portion 32 as it approaches the support portion P2. Also in this case, the width W2 of the extending portion 32 is wider than the width W1 of the extending portion 22 over the entire length, and the width W2 of the bent portion 33 is wider than the width W1 of the bent portion 23. In addition, the point that the dimensional difference between the width W1 and the width W2 is more than a minute dimensional difference due to manufacturing errors or errors during deformation, and the ratio thereof is the same as the distances L1 and L2. be.

As shown in FIG. 3, the height H1 of the rising portion 21 of the first arm portion 20 from the fixing plate portion 10 (see FIG. 3(a)) is equal to It is higher than the height H2 from the portion 10 (see FIG. 3(b)). The upper base point of the heights H1 and H2 of the rising portions 21 and 31 from the fixed plate portion 10 is the upper top of the corner between the rising portions 21 and 31 and the extending portions 22 and 32. The lower base point of the heights H1 and H2 of the rising parts 21 and 31 from the fixed plate part 10 is the upper surface of the fixed plate part 10. Further, the height H3 of the rising portion 21 of the first arm portion 20 from the mounting surface 50a is higher than the height H4 of the rising portion 31 of the second arm portion 30 from the mounting surface 50a. The upper base point of the heights H3 and H4 of the rising parts 21 and 31 from the mounting surface 50a is the top of the corner between the rising parts 21 and 31 and the extending parts 22 and 32. The lower base point of the heights H3 and H4 of the rising portions 21 and 31 from the mounting surface 50a is the mounting surface 50a. The heights H1, H2, H3, and H4 are dimensions in the vertical direction (Z-axis direction). Note that the point where the dimensional difference between the heights H1, H3 and the heights H2, H4 is more than a minute dimensional difference due to manufacturing errors or errors during deformation, and the ratio thereof is the distance L1. , has the same purpose as L2.

As shown in FIG. 4, when the top surface 1a of the electronic component 1 is not pressed (steady state), the contact portion 20a of the first arm portion 20 and the contact portion 30a of the second arm portion 30 are connected to the top surface 1a. (on the negative side in the Z-axis direction). The contact portions 20a, 30a are portions that come into contact with the upper surface 1a, and are the lower tops of the corners between the extension portions 22, 32 and the bent portions 23, 33. The contact portion 30a of the second arm portion 30 is arranged below the contact portion 20a of the first arm portion 20. That is, when the upper surface 1a of the electronic component 1 is pressed, the amount of vertical deformation of the second arm portion 30 is larger than the amount of vertical deformation of the first arm portion 20.

Next, the functions and effects of the fixing structure 100 according to this embodiment will be explained.

First, as a comparative example, a configuration in which the first arm section 20 and the second arm section 30 extend linearly from the fixed plate section 10 to the electronic component 1 will be described. Here, to explain a simple cantilever beam model, if the amount of displacement at the tip is the same, the longer the length of the beam, the smaller the load acting on the tip. Considering this model, in the comparative example, the total length of the second arm section 30 is longer than the total length of the first arm section 20, so the pressing force of the second arm section 30 is greater than that of the first arm section. It can be said that the pressing force tends to be smaller than that of No. 20. Therefore, the fixing structure according to the comparative example has a problem in that the fixing tool cannot press the electronic component 1 with a uniform pressing force. In order to obtain a fixing structure that presses the electronic component 1 with a uniform pressing force, the arrangement and shape of the fixing plate part 10, the fixing part 55, the first arm part 20, and the second arm part 30 should be well-balanced. It is necessary to For example, a well-balanced configuration is adopted, such as having both arm parts 20 and 30 in the same shape and symmetrically disposing them with respect to the Y axis, and placing the fixing part 55 in the center between both arm parts 20 and 30. (For example, Patent Document 1). However, when adopting such a well-balanced fixing structure, when designing the arrangement of components around the electronic component 1, it is necessary to arrange the components so as not to interfere with the fixing tool or the fixing part. That is, since the arrangement of components on the board 50 must be designed with priority given to the balance of the fixing structure, there is a problem that the structure of the board 50 is subject to restrictions.

On the other hand, in the fixing structure 100 according to the present embodiment, the first arm part 20 and the second arm part 30 are bent toward the side opposite to the substrate 50 at the edge of the fixing plate part 10, and the structure Standing portions 21 and 31 extend in a direction away from the object, and support portions P1 on the tip side bend towards the substrate 50 side at the tip sides of the rising portions 21 and 31 and extend in a direction approaching the substrate 50 side. , P2. Therefore, the first arm part 20 and the second arm part 30 press the electronic component 1 with the support parts P1 and P2 on the tip side of the extension parts 22 and 32, respectively.

In plan view, the distance L1 between the support part P1 of the first arm part 20 and the fixed plate part 10 is longer than the distance L2 between the support part P2 of the second arm part 30 and the fixed plate part 10. short. In contrast to this configuration, in the fixing structure 100 according to the present embodiment, the height H3 of the rising portion 21 of the first arm portion 20 from the mounting surface 50a is greater than the mounting surface 50a of the rising portion 31 of the second arm portion 30. The height from H4 is higher than H4. In this case, since the entire length of the first arm section 20 can be increased, the pressing force of the first arm section 20 can be suppressed. That is, by adjusting the heights H1 and H2 of the rising parts 21 and 31 of each arm part 20 and 30, it is possible to adjust the pressing force of each arm part 20 and 30.

In this case, even if the configuration of each arm portion 20, 30 and fixing portion 55 in a plan view becomes unbalanced depending on the arrangement of components around the electronic component 1, the height H1 of the rising portion 21, 31, A desired pressing force can be obtained by adjusting H2. That is, in the fixing structure 100, one fixing part 55 is disposed at a position closer to the positive side in the X-axis direction with respect to the arm parts 20, 30, and the arm parts 20, 30 are arranged in an unbalanced manner such that they are inclined to each other. The structure is as follows. In the case of such an unbalanced configuration, components can be freely placed on the mounting surface 50a of the board 50 in a region on the negative side of the fixture 2 in the X-axis direction. By arranging components freely around the fixture 2 in this way, even if the fixing structure 100 has an unbalanced structure, the fixture 2 can place the electronic components 1 approximately uniformly on each arm 20, 30. It can be pressed with a certain pressing force. As described above, restrictions on the structure of the structure in which the electronic component 1 is mounted can be reduced.

The width W2 of the second arm portion 30 is wider than the width W1 of the first arm portion 20. In this case, the pressing force of the second arm portion 30 can be increased. In this way, by adjusting the widths W1 and W2 in addition to adjusting the heights H1 and H2 of the arm portions 20 and 30, the pressing force can be adjusted easily.

The rising portion stands up perpendicularly to the fixed plate portion. In this case, the model for calculating the pressing force of each arm portion 20, 30 can be simplified, and thus the ease of design can be improved.

In the above-described embodiment, a case has been described in which the first arm section 20 and the second arm section 30 press the electronic component 1 with a substantially uniform pressing force. However, the present invention can also be employed in a case where the pressing force of the first arm section 20 and the pressing force of the second arm section 30 are intentionally made different. For example, the design may be such that the pressing force of the second arm part 30 is greater than the pressing force of the first arm part 20. In this way, by adjusting the heights H1, H2, etc. of each arm portion 20, 30, it becomes possible to press the electronic component 1 in any pressing manner.

The fixture 2 is a fixture 2 that presses and fixes the electronic component 1 mounted on the mounting surface 50a of the board 50, and includes a fixing plate portion 10 fixed to the boss 51 and a plan view of the fixing plate portion 10. includes at least a first arm part 20 and a second arm part 30 extending from the fixing plate part 10 to the outside with respect to the fixing plate part 10, and the direction perpendicular to the main surface 10a of the fixing plate part 10 is the Z-axis. direction (first direction), the first arm portion 20 and the second arm portion 30 are bent toward the positive side in the Z-axis direction at the edge of the fixed plate portion 10, and the first arm portion 20 and the second arm portion 30 are bent toward the positive side in the Z-axis direction The rising portions 21 and 31 extend toward the positive side, and the rising portions 21 and 31 are bent toward the negative side in the Z-axis direction at the distal ends of the rising portions 21 and 31, and extend toward the negative side in the Z-axis direction. It includes extending portions 22 and 32 that press the electronic component 1 at the supporting portions P1 and P2, and the distance L1 between the supporting portion P1 of the first arm portion 20 and the fixing plate portion 10 in plan view is as follows: The height H1 of the rising part 21 of the first arm part 20 from the fixed plate part 10 is shorter than the distance L2 between the support part P2 of the second arm part 30 and the fixed plate part 10. It is higher than the height H2 of the rising portion 31 of the arm portion 30 from the fixed plate portion 10.

This fixture 2 can provide the same functions and effects as the fixing structure 100 described above.

The invention is not limited to the embodiments described above. For example, the structure of the arm parts 20, 30 and the position of the fixing part 55 in the above-described embodiments are merely examples, and can be changed as appropriate. That is, depending on how components are arranged around the electronic component 1, the shape of the fixture 2 and the arrangement of the fixing portion 55 may be changed as appropriate. Further, the configuration of each arm portion 20, 30 may be changed in accordance with the change. Further, the number of arm portions of the fixture 2 is not limited to two, and may have three or more. Moreover, the fixing part 55 of the fixture 2 does not need to be provided at only one location, and may be provided at multiple locations. Further, in the above-described embodiment, the fixture 2 presses one electronic component 1, but a plurality of electronic components 1 may be pressed by one fixture 2. In this case, one arm presses one electronic component 1, and the other arm presses another electronic component 1. For example, a fixing structure 200 and a fixture 102 as shown in FIG. 5 may be employed. The fixed structure 200 has two electronic components 1A and 1B arranged in the X-axis direction. The fixture 102 presses the electronic component 1A with the arm portions 120 and 130, and presses the electronic component 1B with the arm portion 140. In plan view, the distance between the support part P1 of the arm part 120 and the fixed plate part 110 is shorter than the distance between the support part P2 of the arm part 130 and the fixed plate part 110, and the distance between the support part P1 of the arm part 120 and the fixed plate part 110 is is higher than the height of the rising portion of the arm portion 130. In plan view, the distance between the support part P3 of the arm part 140 and the fixed plate part 110 is shorter than the distance between the support parts P1, P2 of the arm parts 120, 130 and the fixed plate part 110, The height of the rising portion 140 is higher than the height of the rising portions of the arm portions 120 and 130. In this case, when the arm portion 140 is viewed as a “first arm portion”, the arm portions 120 and 130 correspond to a “second arm portion”. When the arm portion 120 is viewed as a “first arm portion”, the arm portion 130 is a “second arm portion”.

Moreover, although the rising parts 21 and 31 of each arm part 20 and 30 stood up perpendicular|vertically with respect to the fixed plate part 10, they may stand up so that it may incline with respect to an up-down direction.
