Description

Technical Field

[0001] This invention relates to a pressing unit and a spring component. Background Technology

[0002] A spring component is known, which is disposed between a first pressing body and a second pressing body to apply pressure to one or both of them. The spring component is used in various devices. For example, the spring component fixes a power element to a heat sink, which dissipates heat generated in the power element to the outside (see, for example, Patent Document 1). The spring component described in Patent Document 1 has a bent portion and a cut-out portion on a plate-shaped component, the cut-out portion being pressed against the power element to apply a load to the power element. Furthermore, the spring component inserts the bent portion into a hole in a pressing part, thereby fixing it to the pressing part. In this case, the pressing part is fixed to the heat sink.

[0034] In the following description, a pressing unit using a spring component will be described as an embodiment for carrying out the present invention (hereinafter referred to as "the embodiment"). However, the present invention is not limited to this embodiment. Furthermore, in the accompanying drawings, the same reference numerals are used to denote the same parts. It should also be noted that the drawings are schematic diagrams, and the thickness-to-width ratio, proportions, etc., of each component may differ from reality. Additionally, the drawings may include portions with different dimensions or proportions.

[0035] Implementation Method 1 Figure 1This is a schematic side view of a pressing unit using the spring member of Embodiment 1 of the present invention. The pressing unit 100 of Embodiment 1 of the present invention is configured such that a spring member 1 is disposed between a first pressed body 101 and a second pressed body 102. The spring member 1 applies pressure to both the first pressed body 101 and the second pressed body 102 through elastic force.

[0036] The first pressed body 101 is a bottomed cylindrical shape with one end open and the other end having a bottom. Figure 1 The first pressed body 101 shown is a hollow prism with a bottom and an opening on the left side of the figure.

[0037] The second pressed body 102 is prismatic and is housed within the first pressed body 101.

[0038] Figure 2 This is a diagram illustrating the assembly of the pressing unit. The pressing unit 100 is assembled such that the second pressed body 102 slides relative to the first pressed body 101 and is inserted into the first pressed body 101.

[0039] Figure 3 and Figure 4 This is a perspective view showing the structure of the spring component according to Embodiment 1 of the present invention. Figure 5 yes Figure 4 The side view in the direction of arrow A. Figure 6 This is a top view showing the structure of the spring component according to Embodiment 1 of the present invention. Wherein, Figure 6 This is a simplified schematic representation of the spring component, omitting details such as the through hole 14 described later. In the following figures, the X, Y, and Z directions are orthogonal to each other. Furthermore, in the following explanation, the X direction is assumed to be the extension direction (length direction) of the spring portion, the Y direction to be the width direction, and the Z direction to be the height direction.

[0040] Spring component 1 is formed using a flat spring steel made of metal, resin, or the like. For example, spring component 1 is formed by stamping the flat spring steel into the shape of spring component 1 and partially bending it.

[0041] The spring component 1 includes: two first spring portions (first spring portions 10A and 10B), one second spring portion 20, a first connecting portion 30A for connecting the first spring portion 10A and the second spring portion 20, and a second connecting portion 30B for connecting the first spring portion 10B and the second spring portion 20.

[0042] The first spring portions 10A and 10B each have: a strip-shaped main body portion 11, which is bent into an arc shape in the length direction; a first end portion 12, which extends from one end of the main body portion 11 and is bent in a shape opposite to the bending shape of the main body portion 11; and a second end portion 13, which extends from the end of the main body portion 11 on the side opposite to the side where the first end portion 12 extends, and is bent in a shape opposite to the bending shape of the main body portion 11.

[0043] The main body 11 has: a flat portion 11a extending in a flat plate shape; a first connecting portion 11b extending curvedly from one end of the flat portion 11a and connected to a first end portion 12; and a second connecting portion 11c extending curvedly from the other end of the flat portion 11a and connected to a second end portion 13. The first connecting portion 11b and the second connecting portion 11c are curved toward the same side relative to the flat portion 11a.

[0044] In addition, a through hole 14 is formed at the first end 12, extending through the thickness direction. This through hole 14 corresponds to a fixing part.

[0045] Furthermore, in this embodiment 1, the first spring portion 10A and the first spring portion 10B are described as having the same shape and size, but they may also have different shapes such as bending forms or sizes. Here, "same shape" means "same," including manufacturing errors, etc.

[0046] The first spring portions 10A and 10B are arranged side-by-side in the Y direction with their curved shapes aligned. Specifically, the first spring portions 10A and 10B are arranged side-by-side in the Y direction with the curved protrusions facing the same direction. That is, they are arranged such that the tips of the protrusions are oriented towards the height direction by bending. In this case, for example, in the first spring portions 10A and 10B, the ends of each first end portion 12 are located on the same XY plane and on the same YZ plane.

[0047] The second spring portion 20 has: a strip-shaped main body portion 21, which is bent into an arc shape in the length direction; a first end portion 22, which extends from one end of the main body portion 21 and is bent in a shape opposite to the bending shape of the main body portion 21; and a second end portion 23, which extends from the end of the main body portion 21 on the side opposite to the side where the first end portion 22 extends, and is bent in a shape opposite to the bending shape of the main body portion 21.

[0048] The main body 21 has: a flat portion 21a extending in a flat plate shape; a first connecting portion 21b extending curvedly from one end of the flat portion 21a and connected to a first end portion 22; and a second connecting portion 21c extending curvedly from the other end of the flat portion 21a and connected to a second end portion 23.

[0049] The second spring portion 20 may have the same shape as the first spring portion 10A (10B), or it may have a different shape, such as a curved shape or a different size.

[0050] The second spring portion 20 is located between the first spring portions 10A and 10B in the Y direction, and is offset relative to the first spring portions 10A and 10B in the X direction. At this time, one end (first end portion 22) of the second spring portion 20 is offset relative to the first end portion 12 towards the second end portion 13.

[0051] In addition, the first spring portions 10A, 10B and the second spring portion 20 are arranged in such a way that the orientation of the bent protrusions is consistent in the height direction.

[0052] Among them, the first end portions 12, 22 and the second end portions 13, 23 extend from the main body portions 11, 21 in a curved manner, and can extend parallel to the flat portions 11a, 21a, or can be adjusted to become an angle parallel to the contact surface of the first pressed body 101 after the second pressed body 102 is assembled to the first pressed body 101.

[0053] One end of the first connecting part 30A is connected to the flat part 11a of the first spring part 10A, and the other end is connected to the flat part 21a of the second spring part 20.

[0054] One end of the second connecting portion 30B is connected to the flat portion 11a of the first spring portion 10B, and the other end is connected to the flat portion 21a of the second spring portion 20. The second connecting portion 30B is connected to the side of the second spring portion 20 opposite to the side connected to the first connecting portion 30A in the width direction.

[0055] The first connecting portion 30A and the second connecting portion 30B extend in a direction parallel to the plane (here, the XY plane) through which the flat portions 11a and 21a of the main body portion 11 and the main body portion 21 pass. That is, the first connecting portion 30A and the second connecting portion 30B are located at the ends opposite to the first ends 12 and 22 and the second ends 13 and 23 in the height direction.

[0056] In the pressing unit 100, the spring component 1 is fixed inside the first pressed body 101 (see [reference]). Figure 1 Specifically, the spring component 1 is fixed to the inner wall of the first pressed body 101 by a bolt 103 installed on the opening side of the first pressed body 101. At this time, the shaft portion of the bolt 103 passes through the through hole 14, and the first end 12 is clamped and fixed by the head and the first pressed body 101. Furthermore, the extending directions of the first spring portions 10A and 10B and the second spring portion 20 are approximately the same as the direction from the opening toward the bottom (see...). Figure 2 ).

[0057] also, Figure 2 The illustration shows an example where the second end 13, the first end 22, and the second end 23 are in contact with the first pressed body 101. However, as long as the first end 12, which is fixed by the bolt 103, is in contact with the first pressed body 101, the load can be adjusted by the contact method of each end.

[0058] Next, refer to Figures 7-9 The operation of the spring components during the assembly of the pressing unit is explained. Figures 7-9 This is a diagram illustrating the operation of the spring component during the assembly of the pressing unit according to Embodiment 1 of the present invention.

[0059] When the second pressed body 102 is inserted into the first pressed body 101, the second pressed body 102 abuts against the first connecting portion 11b of the first spring portions 10A and 10B respectively (see...). Figure 7 At this time, the first spring parts 10A and 10B deform due to contact with the second pressed body 102.

[0060] Subsequently, the second pressed body 102 slides relative to the flat portion 11a of the main body 11 and interacts with the first connecting portion 30A and the second connecting portion 30B. Figures 7-9 Only the first connecting part 30A is shown in the image (see [reference]). Figure 8 The first connecting portion 30A and the second connecting portion 30B deform upon contact with the second pressed body 102. By bringing the second pressed body 102 into contact with the first connecting portion 30A and the second connecting portion 30B, the change in load borne by the spring member 1 when the second pressed body 102 contacts the second spring portion 20 can be reduced.

[0061] Then, the second pressed body 102 slides relative to the first connecting portion 30A and the second connecting portion 30B, and comes into contact with the second spring portion 20. The second spring portion 20 deforms due to contact with the second pressed body 102. When the second pressed body 102 is assembled to the first pressed body 101 (see...), Figure 1 The second pressed body 102 contacts the flat portions 11a, 21a and the connecting portion. Furthermore, depending on the deformation mode of the spring component 1, its contact position with the second pressed body 102 is not limited to the above description, for example, it may only contact the flat portions 11a, 21a, etc.

[0062] During this assembly, when the spring component 1 is subjected to a load toward the bottom side of the first pressed body 101 due to the sliding of the second pressed body 102, its first end 12 is fixed by the bolt 103, thus preventing it from shifting position relative to the first pressed body 101. At this time, since the bolt 103 is installed on the upstream side of the sliding direction of the second pressed body 102 (the opening side of the first pressed body 101), even if a load is applied when the second pressed body 102 is inserted, it can extend in the X direction with the bolt 103 as a fulcrum and smoothly displace in the Z direction.

[0063] Furthermore, since each spring part is bent along the sliding direction of the second pressed body 102, the spring member 1 can make the second pressed body 102 move smoothly when it contacts the spring member 1 and slides.

[0064] Furthermore, the first spring portions 10A and 10B and the second spring portion 20 are connected by a connecting portion that connects their top ends (here referring to the flat portions 11a and 21a), and when the second pressed body 102 is inserted, the second pressed body 102 contacts the connecting portion. Therefore, the spring component 1 can reduce the change in load when the second pressed body 102 contacts the second spring portion 20 after contacting the first spring portions 10A and 10B.

[0065] According to Embodiment 1 described above, in the structure in which the second pressed body is assembled by sliding relative to the first pressed body, the second pressed body can be reliably and stably pressed against the first pressed body.

[0066] Furthermore, in the above embodiment 1, it is also possible to have a structure that only includes the first spring portion 10A, the first connecting portion 30A, and the second spring portion 20.

[0067] Alternatively, in the above embodiment 1, it can also be a structure having one first spring portion and two second spring portions, that is, a structure in which the second spring portion is replaced with the first spring portion and the first spring portion is replaced with the second spring portion.

[0068] Variation 1 of Implementation Method 1 Next, refer to Figure 10 and Figure 11 A variation of this embodiment 1 will be described. Figure 10 and Figure 11 This is a perspective view showing the structure of a spring component according to a modified example 1 of Embodiment 1 of the present invention. In this modified example 1, the spring component 1 of Embodiment 1 is further provided with a third connecting portion 30C that connects the first connecting portion 30A and the second connecting portion 30B. Hereinafter, the parts that differ from Embodiment 1 will be described, and the same constituent elements will be labeled with the same symbols and the description will be omitted.

[0069] The spring component 1A of this modified example 1 includes: two first spring portions (first spring portions 10A and 10B), one second spring portion 20, a first connecting portion 30A for connecting the first spring portion 10A and the second spring portion 20, a second connecting portion 30B for connecting the first spring portion 10B and the second spring portion 20, and a third connecting portion 30C for connecting the first connecting portion 30A and the second connecting portion 30B.

[0070] One end of the third connecting part 30C is connected to the end of the first connecting part 30A in the extending direction (X direction) on the side connected to the main body 11 of the first spring part 10A, and the other end is connected to the end of the second connecting part 30B in the extending direction (X direction) on the side connected to the main body 11 of the first spring part 10B.

[0071] Similar to the spring component 1 in Embodiment 1, the spring component 1A is mounted to the first pressed body 101 by bolts 103, and the pressing unit is assembled by inserting the second pressed body 102.

[0072] Similar to Embodiment 1, in this modified example 1, since the first end 12 is fixed by the bolt 103, positional displacement relative to the first pressed body 101 is suppressed, and the second pressed body 102 can be smoothly inserted by means of the curved shape of the spring portion and the connecting portion. According to this modified example 1, in the structure in which the second pressed body is assembled by sliding relative to the first pressed body, the second pressed body can be reliably and stably pressed against the first pressed body.

[0073] Furthermore, according to the spring component 1A of Modified Example 1, the first connecting part 30A and the second connecting part 30B are connected by the third connecting part 30C. Therefore, it is possible to suppress the first spring parts 10A and 10B from moving away from each other when a load is applied to the spring component 1A, and to maintain the relative positional relationship of the first spring parts 10A and 10B.

[0074] Variation 2 of Implementation Method 1 Next, refer to Figure 12 and Figure 13 A variation of Embodiment 1, Example 2, will be described. Figure 12 and Figure 13 This is a perspective view showing the structure of the spring component in Modification 2 of Embodiment 1 of the present invention. In this Modification 2, three first spring portions and two second spring portions are provided. Hereinafter, the parts that differ from Embodiment 1 will be described, and the same components will be labeled with the same symbols and their descriptions will be omitted.

[0075] The spring component 1B of this modified example 2 includes: three first spring parts (first spring parts 10A, 10B, 10C), two second spring parts (second spring parts 20A, 20B), a first connecting part 30A for connecting the first spring part 10A and the second spring part 20A, a second connecting part 30B for connecting the first spring part 10B and the second spring part 20A, a third connecting part 30D for connecting the first spring part 10B and the second spring part 20B, and a fourth connecting part 30E for connecting the first spring part 10C and the second spring part 20B.

[0076] The first spring section 10C has the same shape as the first spring sections 10A and 10B.

[0077] The second spring sections 20A and 20B have the same shape as the second spring section 20.

[0078] One end of the first connecting part 30A is connected to the flat part 11a of the first spring part 10A, and the other end is connected to the flat part 21a of the second spring part 20A.

[0079] One end of the second connecting portion 30B is connected to the flat portion 11a of the first spring portion 10A, and the other end is connected to the flat portion 21a of the second spring portion 20A. The second connecting portion 30B is connected to the side of the second spring portion 20A opposite to the side connected to the first connecting portion 30A in the width direction.

[0080] One end of the third connecting part 30D is connected to the flat part 11a of the first spring part 10B, and the other end is connected to the flat part 21a of the second spring part 20B.

[0081] One end of the fourth connecting part 30E is connected to the flat part 11a of the first spring part 10C, and the other end is connected to the flat part 21a of the second spring part 20B. The fourth connecting part 30E is connected to the side of the second spring part 20B opposite to the side connected to the third connecting part 30C in the width direction.

[0082] Similar to the spring component 1 in Embodiment 1, the spring component 1B is mounted to the first pressed body 101 by bolts 103, and the pressing unit is assembled by inserting the second pressed body 102. At this time, the first spring portion 10C, the second spring portions 20A and 20B, and the first connecting portions 30A to the fourth connecting portions 30E are deformed in the same manner as the corresponding constituent elements (first spring portions 10A and 10B, second spring portions 20A, and first connecting portions 30A and second connecting portions 30B).

[0083] Similar to Embodiment 1, in this modified example 2, since the first end 12 is fixed by the bolt 103, positional displacement relative to the first pressed body 101 is suppressed, and the second pressed body 102 can be smoothly inserted by means of the curved shape of the spring portion and the connecting portion. According to this modified example 1, in the structure in which the second pressed body is assembled by sliding relative to the first pressed body, the second pressed body can be reliably and stably pressed against the first pressed body.

[0084] Furthermore, according to Modification 2, compared to the spring component 1 of Embodiment 1, there are more spring components, thus enabling the second pressed body 102 to be fixed to the first pressed body 101 in a more balanced and stable manner.

[0085] Furthermore, in Modification 2, a connecting portion (third connecting portion 30C) of Modification 1 or a connecting portion for connecting the third connecting portion 30D and the fourth connecting portion 30E may also be provided.

[0086] Alternatively, in Modification 2, a structure can be adopted in which the positions of the second spring portions 20A and 20B are staggered in the X direction.

[0087] Variation 3 of Implementation Method 1 Next, refer to Figure 14 A variation of Embodiment 1, Example 3, will be described. Figure 14 This is a top view showing the structure of the spring component in Modification 3 of Embodiment 1 of the present invention. In this Modification 3, the first spring portion 10A and the first spring portion 10B are offset in the X direction from the structure of the spring component 1 of Embodiment 1. Hereinafter, the parts that are different from those in Embodiment 1 will be described, and the same constituent elements will be marked with the same symbols and the description will be omitted.

[0088] The spring component 1C of this modified example 3 includes: two first spring portions (first spring portions 10A and 10B), one second spring portion 20, a first connecting portion 30A for connecting the first spring portion 10A and the second spring portion 20, and a second connecting portion 30F for connecting the first spring portion 10B and the second spring portion 20.

[0089] In the spring component 1C, the first spring portion 10B is offset toward the second spring portion 20 in the X direction relative to the first spring portion 10A. Therefore, in the spring component 1C, the first spring portion 10A protrudes toward the side opposite to the second spring portion 20 in the X direction. In addition, the second connecting portion 30F is shorter in the X direction than the first connecting portion 30A.

[0090] Similar to the spring component 1 in Embodiment 1, the spring component 1C is mounted to the first pressed body 101 by bolts 103, and the pressing unit is assembled by inserting the second pressed body 102. At this time, after the second pressed body 102 contacts the first spring portion 10A, it sequentially contacts the first spring portion 10B, the first connecting portion 30A, the second connecting portion 30F, and the second spring portion 20. Furthermore, the first spring portions 10A, 10B, the second spring portion 20, and the first connecting portion 30A and the second connecting portion 30F are deformed in the same manner as their corresponding constituent elements (first spring portions 10A, 10B, second spring portion 20, and first connecting portion 30A and second connecting portion 30B).

[0091] Similar to Embodiment 1, in this modified example 3, since the first end 12 is fixed by the bolt 103, positional displacement relative to the first pressed body 101 is suppressed, and the second pressed body 102 can be smoothly inserted by means of the curved shape of the spring portion and the connecting portion. According to this modified example 3, in the structure in which the second pressed body is assembled by sliding relative to the first pressed body, the second pressed body can be reliably and stably pressed against the first pressed body.

[0092] Variation 4 of Implementation Method 1 Next, refer to Figure 15 A variation of embodiment 1, number 4, will be described. Figure 15 This is a top view showing the structure of the spring component in Modification 4 of Embodiment 1 of the present invention. Hereinafter, the parts that differ from Embodiment 1, etc., will be described, and the same components will be labeled with the same symbols and the description will be omitted.

[0093] The spring component 1D of this modified example 4 includes: two first spring portions (first spring portions 10A, 10B), two second spring portions (second spring portions 20A, 20B), and a connecting portion 30G for connecting the first spring portions 10A, 10B and the second spring portions 20A, 20B. In the spring component 1D, the first spring portions and the second spring portions are arranged in a straight line along the X direction.

[0094] The connecting part 30G is provided in the Y direction between the first spring part 10A and the first spring part 10B, and between the second spring part 20A and the second spring part 20B. One end of the connecting part 30G is connected to the flat part 11a of the first spring part 10A and 10B respectively, and the other end is connected to the flat part 21a of the second spring part 20A and 20B respectively.

[0095] Similar to the spring component 1 in Embodiment 1, the spring component 1D is mounted to the first pressed body 101 by bolts 103, and the pressing unit is assembled by inserting the second pressed body 102. At this time, after the second pressed body 102 contacts the first spring parts 10A and 10B, it contacts and deforms in sequence with the connecting part 30G and the second spring parts 20A and 20B.

[0096] Similar to Embodiment 1, in this modified example 4, since the first end 12 is fixed by the bolt 103, positional displacement relative to the first pressed body 101 is suppressed, and the second pressed body 102 can be smoothly inserted by means of the curved shape of the spring portion and the connecting portion. According to this modified example 4, in the structure in which the second pressed body is assembled by sliding relative to the first pressed body, the second pressed body can be reliably and stably pressed against the first pressed body.

[0097] According to the above-described modified example 4, since the first spring part and the second spring part are arranged in a straight line along the X direction and the spring parts are connected by a connecting part 30G, the size in the Y direction can be reduced compared to the structure of the spring component 1 in embodiment 1.

[0098] Variation 5 of Implementation Method 1 Next, refer to Figure 16 A variation of embodiment 1, number 5, will be described. Figure 16 This is a top view showing the structure of the spring component in Modification 5 of Embodiment 1 of the present invention. Hereinafter, the parts that differ from Embodiment 1, etc., will be described, and the same components will be labeled with the same symbols and the description will be omitted.

[0099] The spring component 1E of this modified example 5 includes: a first spring part 10, a second spring part 20, and a first connecting part 30H and a second connecting part 30I for connecting the first spring part 10 and the second spring part 20.

[0100] The first spring section 10 and the second spring section 20 are arranged side by side in the X direction.

[0101] One end of the first connecting part 30H is connected to the flat part 11a of the first spring part 10, and the other end is connected to the flat part 21a of the second spring part 20.

[0102] One end of the second connecting portion 30I is connected to the flat portion 11a of the first spring portion 10, and the other end is connected to the flat portion 21a of the second spring portion 20. The second connecting portion 30I is connected to the side of the first spring portion 10 and the second spring portion 20 opposite to the side connected to the first connecting portion 30H in the width direction.

[0103] Similar to the spring component 1 in Embodiment 1, the spring component 1E is mounted to the first pressed body 101 by bolts 103, and the pressing unit is assembled by inserting the second pressed body 102. At this time, after the second pressed body 102 contacts the first spring part 10, it contacts and deforms in sequence with the first connecting part 30H, the second connecting part 30I, and the second spring part 20.

[0104] Similar to Embodiment 1, in this modified example 5, since the first end 12 is fixed by the bolt 103, positional displacement relative to the first pressed body 101 is suppressed, and the second pressed body 102 can be smoothly inserted by means of the curved shape of the spring portion and the connecting portion. According to this modified example 5, in the structure in which the second pressed body is assembled by sliding relative to the first pressed body, the second pressed body can be reliably and stably pressed against the first pressed body.

[0105] Implementation Method 2 Next, refer to Figure 17 This second embodiment will be described. Figure 17 This is a perspective view showing the structure of the spring member according to Embodiment 2 of the present invention. In Embodiment 2, compared with the structure of the spring member 1 of Embodiment 1, a tongue portion is also provided. Hereinafter, the parts that differ from Embodiment 1 will be described, and the same constituent elements will be marked with the same symbols and the description will be omitted.

[0106] The spring component 1F of this embodiment 2 includes: two first spring portions (first spring portions 10A and 10B), one second spring portion 20, a first connecting portion 30A for connecting the first spring portion 10A and the second spring portion 20, a second connecting portion 30B for connecting the first spring portion 10B and the second spring portion 20, a first tongue portion 40A extending from the first connecting portion 30A, and a second tongue portion 40B extending from the second connecting portion 30B.

[0107] The first tongue portion 40A extends from the end of the first connecting portion 30A on the side connected to the first spring portion 10A along the extending direction of the first spring portion 10A (corresponding to the X direction here). The first tongue portion 40A is preferably curved in the same way as the corresponding position of the first spring portion 10A in the Y direction, and at least its front end portion is arc-shaped toward the side with the same curvature as the first spring portion 10A.

[0108] The second tongue portion 40B extends from the end of the second connecting portion 30B on the side connected to the first spring portion 10B along the extending direction of the first spring portion 10B (corresponding to the X direction). The second tongue portion 40B is preferably curved in the same way as the corresponding position of the first spring portion 10B in the Y direction, and at least its front end is arc-shaped toward the side with the same curvature as the first spring portion 10B.

[0109] Similar to the spring component 1 in Embodiment 1, the spring component 1F is mounted to the first pressed body 101 by bolts 103, and the pressing unit is assembled by inserting the second pressed body 102. At this time, after contacting the first spring portion 10, the second pressed body 102 contacts the first tongue portion 40A and the second tongue portion 40B. Subsequently, the second pressed body 102 sequentially contacts and deforms the first connecting portion 30A, the second connecting portion 30B, and the second spring portion 20.

[0110] Similar to Embodiment 1, in this Embodiment 2, since the first end 12 is fixed by the bolt 103, positional displacement relative to the first pressed body 101 is suppressed, and the second pressed body 102 can be smoothly inserted by means of the curved shape of the spring portion and the connecting portion. According to this Embodiment 2, in the structure in which the second pressed body is assembled by sliding relative to the first pressed body, the second pressed body can be reliably and stably pressed against the first pressed body.

[0111] Furthermore, according to the spring component 1F of Embodiment 2, by having the second pressed body 102 contact the first tongue portion 40A and the second tongue portion 40B before contacting the first connecting portion 30A and the second connecting portion 30B, the deformation of the first connecting portion 30A and the second connecting portion 30B caused by the contact of the second pressed body 102 can be made smoother. As a result, compared to Embodiment 1, the second pressed body 102 can be assembled to the first pressed body 101 even more smoothly.

[0112] The foregoing has described the methods for implementing the present invention, but the present invention should not be limited to the above embodiments. For example, the spring coefficient of the first spring portion can be made smaller than that of the second spring portion. In this case, the thickness of the first spring portion can be made thinner than that of the second spring portion, or the height of the spring (here, the distance in the Z direction) can be made smaller, or the inclination angle of the connecting portion relative to the flat portion can be made gentler, etc.

[0113] In addition, in embodiments 1, 2 and their variations, ribs may be provided at the connection. The strength of the connection can be adjusted based on the formation of the ribs.

[0114] Furthermore, in embodiments 1, 2, and their variations, the width can gradually decrease from the connecting portion toward the end. By reducing the width of the spring portion toward the end, the mounting area of ​​the connecting portion can be increased, thus increasing the width of the connecting portion; or the distance between the spring portions in the Y direction can be reduced, thereby reducing the Y-direction dimension of the spring components. As long as the Y-direction dimension is reduced, the structure of the present invention can be applied even when the Y-direction dimension at the mounting position is limited, and more spring components can be mounted in the Y direction.

[0115] Alternatively, in embodiments 1, 2, and their variations, the width of the spring portion can gradually increase from the connecting portion toward the end. By increasing the width of the spring portion toward the end, the contact width with the second pressed body 102 can be maintained, while the spring coefficient can be reduced.

[0116] Furthermore, in embodiments 1, 2, and their variations, a portion of the ends of the connecting part in the X direction may be bent in the Z direction in a manner that protrudes toward the side opposite to the bending shape (protrusion direction) of the spring part. Based on this bending of the connecting part, it can be configured such that the second spring part contacts the second pressed body before contacting the connecting part, making the increase in insertion resistance more pronounced and allowing for easier control of the position of the second pressed body relative to the first pressed body.

[0117] In addition, in embodiments 1, 2 and their variations, a first spring portion and a second spring portion may be appropriately added in the X and Y directions, and a connecting portion may also be added accordingly.

[0118] Furthermore, in embodiments 1, 2 and their variations, the structure of the first spring portion having a second end and a second connecting portion has been described, but it is also possible for the structure to not have a second end and a second connecting portion.

[0119] Furthermore, in embodiments 1, 2, and their variations, an example was described in which the spring member 1 was fixed to the first pressed body 101 by inserting a bolt 103 through the through hole 14 formed at the first end 12. However, the method is not limited to fixing using the through hole 14; for example, it could also be a structure that is fixed by welding or the like. In this case, the welded portion (melt mark) formed by welding is equivalent to the fixing portion.

[0120] Thus, the present invention may include various embodiments not described herein, and various design changes may be made without departing from the technical concept defined by the scope of the claims.

[0121] Industrial applicability As described above, the pressing unit and spring component of the present invention are suitable for: in a structure in which the second pressed body is assembled by sliding relative to the first pressed body, to reliably and stably press the second pressed body against the first pressed body.
