[0001] This invention relates to spring components. Background Technology

[0002] A spring component is known, disposed between a first pressed body and a second pressed body, applying pressure to one or both of them. The spring component is used in various devices. For example, the spring component secures a semiconductor module to a cooling component for dissipating heat generated in the semiconductor module to the outside (see, for example, Patent Document 1). The spring component described in Patent Document 1 includes a plurality of disc springs and a support portion for supporting the plurality of disc springs.

In this case, the connecting portions connect the disc springs with the shortest possible distance.

[0003] Patent Document 1: Japanese Patent No. 6197769. Summary of the Invention

[0004] However, spring components with multiple disc springs exhibit non-linear load characteristics, requiring them to apply pressure evenly to the object being pressed. However, if the disc springs are brought closer together and the number of disc springs in the spring component is increased, the length of the connecting portion between the disc springs will be shortened. If the connecting portion is shortened, the stress applied to the connecting portion becomes more concentrated when the spring component is loaded, potentially leading to damage to the connecting portion. On the other hand, if the distance between the disc springs is set to be longer, although the stress applied to the connecting portion is suppressed, the number of disc springs per unit area decreases, which may result in uneven pressure on the object being pressed.

[0005] The present invention was made in view of the above-mentioned problems, and its object is to provide a spring component that can press an object with a uniform pressing load while easing the stress applied to the connection.

[0006] To solve the above problems and achieve the objective, the spring component of the present invention comprises: a plurality of disc springs, which are hollow frustum-shaped; and a first connecting portion that connects a pair of disc springs among the plurality of disc springs to each other, the first connecting portion extending along the plane containing the outer edges of the pair of disc springs and being partially curved.

[0007] Furthermore, the spring component involved in this invention is such that, in the above invention, the first connecting portion has: a first straight portion extending along a straight line passing through the center of one of the paired disc springs and the extension end of the first connecting portion from one disc spring; and a second straight portion extending along a straight line passing through the center of the other disc spring and the extension end of the first connecting portion from the other disc spring.

[0008] Furthermore, the spring component involved in this invention is, in the above invention, wherein the plurality of disc springs are arranged in two intersecting directions, and the plurality of disc springs are all connected together via a plurality of first connecting portions.

[0009] Furthermore, the spring component involved in this invention is configured such that, in the above invention, the plurality of disc springs are arranged in two intersecting directions, and the spring component forms a closed loop through the plurality of disc springs and the plurality of first connecting portions.

[0010] Furthermore, the spring component involved in this invention is, in the above invention, wherein the plurality of disc springs are arranged in concentric circles or in a spiral arrangement.

[0011] Furthermore, the spring component involved in this invention, in the above invention, further comprises: a frame-shaped base; and a second connecting portion that connects the disc springs to the base, the base surrounding the plurality of disc springs and the first connecting portion.

[0012] Furthermore, the spring component involved in this invention is such that, in the above invention, the first connecting portion is connected to the outer edge of the disc spring, and the direction in which the first connecting portion extends from the outer edge is perpendicular to the tangent of the portion extending from the outer edge.

[0013] According to the present invention, the following effects are achieved: the object can be pressed with a uniform pressing load, while the stress applied to the connection can be mitigated. Attached Figure Description

[0031] In the following description, a spring component for the pressing unit 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 differ from reality. Additionally, the drawings also include portions with different dimensions or proportions.

[0032] Implementation Method 1 Figure 1 This is a top view schematically illustrating the structure of the spring component according to Embodiment 1 of the present invention. The spring component 1 according to Embodiment 1 applies pressure to both the first pressed body and the second pressed body through elastic force.

[0033] Spring component 1 is formed using flat spring steel. For example, spring component 1 is formed by stamping flat spring steel to create its shape. Examples of spring steel include carbon tool steel (SK material) and stainless steel (SUS), but it is not limited to these.

[0034] The spring component 1 includes two disc springs 2 and a connecting part (first connecting part) 3 connecting the disc springs 2.

[0035] The disc spring 2 is in the shape of a hollow frustum-cone (a truncated cone), with an inclined surface that slopes from the outer periphery towards the center. The disc spring 2 is circular in shape and has a through hole formed in the center, the through hole having a circular opening and penetrating the disc spring 2. This through hole forms a hole that expands from the center outwards. The disc spring 2, for example, has a uniform plate thickness and is formed in a radially expanding shape. For example, the disc spring 2 is formed by continuously raising a hollow circular plate-shaped component from the outer periphery to the inner periphery.

[0036] Two disc springs 2 are arranged on the same plane with the same through-direction. Each disc spring 2 protrudes in a direction orthogonal to the arrangement direction.

[0037] Furthermore, a gap may also be formed in the disc spring 2. The gap may be formed on either the inner or outer peripheral side, and if it is formed on the outer peripheral side, the gap is provided in a portion other than the connecting portion of the connecting part 3.

[0038] The connecting part 3 is strip-shaped and is used to connect the two disc springs 2. The connecting part 3 has, for example, the same thickness as the disc spring 2. Here, the thickness of the disc spring 2 is equivalent to the distance between the front and back sides of the disc spring 2.

[0039] The connecting portion 3 extends radially from the end of one disc spring 2 along a circle formed by the outer edge of the disc spring 2, and then bends radially along a circle formed by the outer edge of the other disc spring 2, thereby connecting with the outer edge of the other disc spring 2. That is, the connecting portion 3 extends with a partial bend, connecting to both disc springs 2 at its two ends respectively. Furthermore, the connecting portion 3 extends along the plane containing the outer edges of the connected disc springs 2. The outer edges of the pair of disc springs 2 are contained within this plane, and the connecting portion 3 may deviate from a direction orthogonal to this plane within the range of manufacturing tolerances.

[0040] Furthermore, an example of the connecting part 3 being connected to the outer edge of the disc spring 2 has been described, but the connecting part 3 may also be configured to be connected to the inner circumferential side of the outer edge of the disc spring 2.

[0041] In this embodiment 1, the connecting portion 3 is composed of a first straight section 31 and a second straight section 32. The first straight section 31 extends along a straight line L1, which passes through the center of one of the two disc springs 2 in a pair and the extension end of the connecting portion 3 from one disc spring 2. The second straight section 32 extends along a straight line L2, which passes through the center of the other disc spring 2 in a pair and the extension end of the connecting portion 3 from the other disc spring 2. The directions in which the straight lines L1 and L2 extend from the outer edge of the disc spring 2 are consistent with those of the connecting portion 3. The direction of extension is perpendicular to the tangent at the extension portion of the outer edge of the disc spring 2.

[0042] Furthermore, while an example has been described in which the aforementioned straight lines L1 and L2 pass through the center of the disc spring 2 in the connecting portion 3, it is also possible to configure the structure in which the straight lines L1 and L2 do not pass through the center of the disc spring 2. Additionally, the direction in which the connecting portion 3 extends from the outer edge of the disc spring 2 can also extend along a direction not perpendicular to the tangent of the outer edge of the disc spring 2. In this case, by making the extending direction of the connecting portion 3 perpendicular (90°) to the tangent, and ensuring that the angle between the connecting portion 3 and each disc spring 2 it connects to is 90°, stress unevenness can be suppressed.

[0043] Figure 2 and Figure 1 The side view corresponding to arrow A is an example diagram showing the shape of a spring component under load. (See diagram below.) Figure 2 As shown, if a load is applied to the disc spring 2, the disc spring 2 deforms in the direction where the height of the truncated cone (the distance between one end and the other end in the through direction) decreases. Consequently, the connecting portion 3 is subjected to bending stress and simultaneously rolls over. Through this rolling over, the load applied to the connecting portion 3 by the bending stress is reduced.

[0044] Figure 3 This is a top view schematically illustrating an example of the structure of a conventional spring component. The conventional spring component 100 includes two disc springs 101 and a connecting portion 102 connecting the two disc springs 101. The disc springs 101 have the same shape as the disc springs 2. The connecting portion 102 extends in a straight line and connects to the two disc springs 101 at both ends. The connecting portion 102 connects the two disc springs 101 with the shortest possible distance.

[0045] Figure 4 and Figure 3 The side view corresponding to arrow B is an example diagram showing the shape of a spring component under load. (See diagram below.) Figure 2 As shown, if a load is applied to the disc spring 101, the disc spring 101 deforms in the direction where the height of the truncated cone decreases. At this time, the connecting part 102 is only subjected to bending stress and does not curl up. Therefore, the connecting part 102 is subjected to a large load by bending stress and deforms, which may lead to damage.

[0046] In Embodiment 1 described above, the connecting portion 3, which connects the disc springs 2 to each other, is partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portion 3 when the spring component 1 is subjected to a load. According to Embodiment 1, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portion.

[0047] Variation 1 of Implementation Method 1 Next, refer to Figure 5 A variation of this embodiment 1 will be described. Figure 5 This is a top view showing the structure of a spring member in a modified example 1 of Embodiment 1 of the present invention. In this modified example 1, a connecting portion 3A is provided instead of the connecting portion 3 of the spring member 1 in Embodiment 1. Hereinafter, the parts that differ from Embodiment 1 will be described, and the same constituent elements will be labeled with the same symbols and their descriptions will be omitted.

[0048] The spring component 1A of this modified example 1 includes two disc springs 2 and a connecting part (first connecting part) 3A connecting the disc springs 2.

[0049] The connecting portion 3A is strip-shaped and connects the two disc springs 2. The connecting portion 3A extends from the outer edge of one disc spring 2, bends in an arc, and extends to connect with the outer edge of the other disc spring 2. At this time, the connecting portion 3A bends in such a way that it protrudes to the opposite side relative to the line segment connecting the centers of the two disc springs 2. Furthermore, the connecting portion 3A is disposed on the plane containing the outer edges of the disc springs 2. That is, the connecting portion 3A partially bends and extends, connecting to the two disc springs 2 at its two ends respectively.

[0050] Similar to Embodiment 1, in the above-described Modification 1, the connecting portion 3A that links the disc springs 2 to each other is partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portion 3A when the spring component 1A is loaded. According to this Modification 1, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portion.

[0051] Variation 2 of Implementation Method 1 Next, refer to Figure 6 A variation of Embodiment 1, Example 2, will be described. Figure 6 This is a top view showing the structure of a spring component in a modified example 2 of Embodiment 1 of the present invention. In this modified example 2, a connecting portion 3B is provided instead of the connecting portion 3 of the spring component 1 in Embodiment 1. Hereinafter, the parts that differ from Embodiment 1 will be described, and the same constituent elements will be labeled with the same symbols and their descriptions will be omitted.

[0052] The spring component 1B of this modified example 2 includes two disc springs 2 and a connecting part (first connecting part) 3B connecting the disc springs 2.

[0053] The connecting portion 3B is strip-shaped and connects the two disc springs 2. The connecting portion 3B extends from the outer edge of one disc spring 2, bends in an arc, and extends to connect with the outer edge of the other disc spring 2. At this time, the connecting portion 3B bends in a manner that protrudes to the opposite side relative to the line segment connecting the centers of the two disc springs 2. Furthermore, the connecting portion 3B is disposed on the plane containing the outer edges of the disc springs 2. That is, the connecting portion 3B extends in a partially curved manner, connecting to the two disc springs 2 at its two ends respectively.

[0054] Additionally, the connecting portion 3B is formed along the circle L ( Figure 6 The circle L is elliptical in shape and passes through the center of each disc spring 2 from a top-down view along the height direction (axial direction) of the conical platform.

[0055] Similar to Embodiment 1, in Modification 2, the connecting portion 3B where the disc springs 2 are connected is partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portion 3B when the spring component 1B is loaded. According to this Modification 2, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portion.

[0056] Furthermore, according to this modified example 2, compared to the V-shaped structure of the connecting part 3 in embodiment 1 that connects straight lines to each other, the installation space of the connecting part 3B can be reduced.

[0057] Variation 3 of Implementation Method 1 Next, refer to Figure 7 A variation of Embodiment 1, Example 3, will be described. Figure 7 This is a top view showing the structure of a spring member in a modified example 3 of Embodiment 1 of the present invention. In this modified example 3, a connecting portion 3C is provided instead of the connecting portion 3 of the spring member 1 in Embodiment 1. Hereinafter, the parts that differ from Embodiment 1 will be described, and the same constituent elements will be labeled with the same symbols and their descriptions will be omitted.

[0058] The spring component 1C of this modified example 3 includes two disc springs 2 and a connecting part (first connecting part) 3C connecting the disc springs 2.

[0059] The connecting portion 3C is strip-shaped and connects the two disc springs 2. The connecting portion 3C extends radially from the outer edge of one disc spring 2, then bends at a right angle towards the other disc spring 2 and extends further, before bending again at a right angle towards that other disc spring 2, thereby connecting with the outer edge of the other disc spring 2. Furthermore, the connecting portion 3C is disposed on the plane containing the outer edges of the disc springs 2. That is, the connecting portion 3C extends in a partially bent manner, connecting to both disc springs 2 at its two ends respectively.

[0060] also, Figure 7 The example shown is of the connector 3C being bent at a right angle, but it can also be a structure that bends at an angle other than a right angle.

[0061] Similar to Embodiment 1, in the above-described Modification 3, the connecting portion 3C where the disc springs 2 are connected to each other is partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portion 3C when the spring component 1C is subjected to a load. According to this Modification 3, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portion.

[0062] Implementation Method 2 Next, refer to Figure 8 This second embodiment will be described. Figure 8 This is a top view showing the structure of the spring component according to Embodiment 2 of the present invention. Compared with the spring component 1 of Embodiment 1, this Embodiment 2 includes six disc springs 2 and multiple connecting portions. Hereinafter, the parts that differ from Embodiment 1 will be described, and the same components will be labeled with the same symbols and the description will be omitted.

[0063] The spring component 1D of this embodiment 2 includes: six disc springs 2, and connecting portions (first connecting portions) 3, 3D that connect adjacent disc springs 2 to each other. Furthermore, the six disc springs 2 are arranged in two intersecting directions. In this embodiment 2, the six disc springs 2 are arranged in an alternating configuration.

[0064] In the following configuration of disc spring 2, the left-right direction is designated as the row direction, and the up-down direction as the column direction. For example, Figure 8 The disc springs 2 of the spring component 1D shown are arranged in 2 rows and 3 columns (2×3).

[0065] The connecting part 3 is strip-shaped and connects the six disc springs 2 that are adjacent to each other in the row direction. Multiple connecting parts 3 are provided. For example, when the multiple disc springs 2 are arranged in a 2×3 row and column configuration, the disc spring 2 located in the second column of the first row is connected to the disc spring 2 located in the first column of the first row via the connecting part 3, and is connected to the disc spring 2 located in the third column of the first row via a different connecting part 3 than the disc spring 2 located in the first column of the first row.

[0066] In addition, in the spring component 1D, the connecting part 3 is provided on the opposite side, i.e., the outer side, of the adjacent disc springs 2 between rows of disc springs 2.

[0067] The connecting part 3D is strip-shaped and connects the six disc springs 2 that are adjacent to each other in the column direction. Similar to the connecting part 3, the connecting part 3D extends in a bent manner and is connected to two disc springs 2 at each end.

[0068] In this embodiment 2, all disc springs 2 are connected via connecting parts 3 and 3D.

[0069] Similar to Embodiment 1, in Embodiment 2, the connecting portions 3 and 3D that link the disc springs 2 together are partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portions 3 and 3D when the spring component 1D is subjected to a load. According to Embodiment 2, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portions.

[0070] Implementation Method 3 Next, refer to Figure 9 This embodiment 3 will be described. Figure 9 This is a top view showing the structure of the spring component according to Embodiment 3 of the present invention. Compared with the spring component 1 of Embodiment 1, this Embodiment 3 includes nine disc springs 2 and multiple connecting parts. Hereinafter, the parts that are different from those of Embodiment 1 will be described, and the same components will be marked with the same symbols and the description will be omitted.

[0071] The spring component 1E of this embodiment 3 includes: nine disc springs 2, and connecting portions (first connecting portions) 3, 3E that connect adjacent disc springs 2 to each other.

[0072] The connecting part 3 connects the nine disc springs 2 that are adjacent to each other in the row direction. Multiple connecting parts 3 are provided, for example, in multiple disc springs 2... Figure 9 In the case of a 3×3 row and column arrangement, the disc spring 2 located in the second column of the first row is connected to the disc spring 2 located in the first column of the first row via a connecting part 3, and is connected to the disc spring 2 located in the third column of the first row via a connecting part 3 that is different from the connecting part 3 connected to the disc spring 2 located in the first column of the first row.

[0073] In this embodiment 3, when the row and column numbers are labeled in order from top to bottom, the connecting part 3 is configured such that the disc spring 2 of the nth row protrudes between the disc springs 2 of the (n-1)th row.

[0074] The connecting portion 3E is strip-shaped, connecting the nine disc springs 2 that are adjacent to each other in the column direction. Similar to the connecting portion 3, the connecting portion 3E extends in a bent manner, connecting to two disc springs 2 at each end. This embodiment 3 provides two connecting portions 3E. In a plurality of disc springs 2 as... Figure 9 In the case of a 3×3 row and column configuration as shown, one connecting part 3E connects the disc spring 2 located in the first row and third column to the disc spring 2 located in the second row and third column. In addition, another connecting part 3E connects the disc spring 2 located in the second row and first column to the disc spring 2 located in the third row and first column.

[0075] Similar to Embodiment 1, in Embodiment 3, the connecting portions 3 and 3E that link the disc springs 2 together are partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portions 3 and 3E when the spring component 1E is subjected to a load. According to Embodiment 3, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portions.

[0076] Variation 1 of Implementation Method 3 Next, refer to Figure 10 A variation of embodiment 3, example 1, will be described. Figure 10This is a top view showing the structure of the main parts of the spring component in Modified Example 1 of Embodiment 3 of the present invention. In this Modified Example 1, a connecting portion (first connecting portion) 3F is provided instead of the connecting portion 3 of the spring component 1E of Embodiment 3. Hereinafter, the parts that are different from Embodiment 3 will be described, and the same constituent elements will be marked with the same symbols and the description will be omitted.

[0077] In this modified example 1, the connecting part 3F is strip-shaped and connects the two disc springs 2. After extending from the outer edge of one disc spring 2, the connecting part 3F bends toward the other disc spring 2 and connects to the outer edge of the other disc spring 2.

[0078] Similar to Embodiment 3, in Modification 1 described above, the connecting portions 3E and 3F that link the disc springs 2 together are partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portions 3E and 3F when the spring components are subjected to a load. According to this Modification 1, the spring components can press the object with a uniform pressing load while mitigating the stress applied to the connecting portions.

[0079] Furthermore, according to Modified Example 1, the connecting portion 3F is bent in such a way that it is inserted between the disc springs 2 of adjacent rows. Therefore, the length of the connecting portion 3F can be ensured within the space formed by the multiple disc springs. As a result, compared with the connecting portion 3, the extension length of the connecting portion 3F can be increased, and the bending stress can be further reduced.

[0080] Variation 2 of Implementation Method 3 Next, refer to Figure 11 A variation of embodiment 3, example 2, will be described. Figure 11 This is a top view showing the structure of the main parts of the spring component in Modification 2 of Embodiment 3 of the present invention. In this Modification 2, a connecting portion (first connecting portion) 3G is provided instead of the connecting portion 3 of the spring component 1E of Embodiment 3. Hereinafter, the parts that differ from Embodiment 3 will be described, and the same constituent elements will be labeled with the same symbols and the description will be omitted.

[0081] In this modified example 2, the connecting portion 3G is strip-shaped, connecting the two disc springs 2. After extending from the outer edge of one disc spring 2 in the column direction, the connecting portion 3G bends in the row direction, and then bends again in the column direction to connect with the outer edge of the other disc spring 2. The connecting portion 3G is U-shaped with a right-angle bend.

[0082] also, Figure 11 The diagram shows an example where the connecting part 3G is bent at a right angle, but it can also be a structure that bends at an angle other than a right angle.

[0083] Similar to Embodiment 3, in Modification 2 described above, the connecting portions 3E and 3G that link the disc springs 2 together are partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portions 3E and 3G when the spring components are subjected to a load. According to this Modification 2, the spring components can press the object with a uniform pressing load while mitigating the stress applied to the connecting portions.

[0084] Implementation Method 4 Next, refer to Figure 12 This embodiment 4 will be described. Figure 12 This is a top view showing the structure of the spring component according to Embodiment 4 of the present invention. Compared with the spring component 1 of Embodiment 1, this Embodiment 4 includes nine disc springs 2 and multiple connecting portions. Hereinafter, the parts that differ from Embodiment 1 will be described, and the same components will be labeled with the same symbols and the description will be omitted.

[0085] The spring component 1F of this embodiment 4 includes: nine disc springs 2, and connecting portions (first connecting portions) 3H and 3I that connect adjacent disc springs 2 to each other. In this embodiment 4, the nine disc springs 2 are arranged in a 3×3 configuration, and the disc spring 2 located in the center (second row, second column) is connected to the disc springs 2 located around it via any one of the connecting portions 3H and 3I.

[0086] The connecting part 3H connects the central disc spring 2 to the corner disc springs 2 among the nine disc springs 2. The connecting part 3H is partially curved into an arc shape, connecting to two disc springs 2 at each end. Multiple connecting parts 3H are provided; for example, the connecting part 3H connects the central disc spring 2 to the disc spring 2 located in the first row and first column (…). Figure 12 The disc spring 2 (located in the upper left corner) is connected to the disc spring 2 located in the center. Additionally, the connecting part 3H connects the disc spring 2 located in the center to the disc spring located in the third column of the first row (…). Figure 12 2. Disc spring located in the upper right corner of the third row, first column. Figure 12 The disc spring 2 (located in the lower left corner) and the disc spring located in the third row and third column ( Figure 12 The disc springs 2 (located at the lower right) are connected respectively.

[0087] The connecting part 3I connects the central disc spring 2 to the disc springs 2 located outside the corners of the nine disc springs 2. Similar to the connecting part 3, the connecting part 3I extends in a bent manner, connecting to two disc springs 2 at each end. Multiple connecting parts 3I are provided; for example, the connecting part 3I connects the central disc spring 2 to the disc spring 2 located in the first row and second column (…). Figure 14 The disc spring 2 (located above the center) is connected to the disc spring 2 located in the center. Additionally, the connecting part 3I connects the disc spring 2 located in the center to the disc spring located in the first column of the second row (…). Figure 142. Disc spring located in the center left) of the second row and third column. Figure 14 The disc spring 2 (located on the right side of the center) and the disc spring located in the second column of the third row ( Figure 14 The disc springs 2 (located in the lower center of the center) are connected respectively.

[0088] Similar to Embodiment 1, in Embodiment 4, the connecting portions 3H and 3I that connect the disc springs 2 to each other are partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portions 3H and 3I when the spring component 1F is loaded. According to Embodiment 4, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portions.

[0089] Implementation Method 5 Next, refer to Figure 13 This embodiment 5 will be described. Figure 13 This is a top view showing the structure of the spring member according to Embodiment 5 of the present invention. In this Embodiment 5, compared with the spring member 1D of Embodiment 2, a connecting portion 3J is also provided. Hereinafter, the parts that differ from Embodiment 2 will be described, and the same components will be labeled with the same symbols and the description will be omitted.

[0090] The spring component 1G of this embodiment 5 includes: six disc springs 2, and connecting portions (first connecting portions) 3, 3D, and 3J that connect adjacent disc springs 2 to each other.

[0091] The connecting part 3J is strip-shaped and connects the six disc springs 2 that are adjacent to each other in the column direction and that are different from the disc springs 2 connected to the connecting part 3D. Similar to the connecting parts 3 and 3D, the connecting part 3J extends in a bent manner and is connected to two disc springs 2 at each of its two ends.

[0092] The spring component 1G is formed into a closed loop based on the disc spring 2 and the connecting parts 3, 3D, and 3J.

[0093] Similar to Embodiment 2, in Embodiment 5, the connecting portions 3, 3D, and 3J that connect the disc springs 2 to each other are partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portions 3, 3D, and 3J when the spring component 1G is subjected to a load. According to Embodiment 5, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portions.

[0094] Furthermore, according to embodiment 5, the spring component 1G is formed into a closed loop shape based on the disc spring 2 and the connecting portions 3, 3D, and 3J, so that the relative positional relationship of the disc spring 2 can be maintained compared to the spring component 1D.

[0095] Implementation Method 6 Next, refer to Figure 14 This embodiment 6 will be described. Figure 14 This is a top view showing the structure of the spring member according to Embodiment 6 of the present invention. In this Embodiment 6, compared with the spring member 1E of Embodiment 3, a connecting portion 3K is also provided. Hereinafter, the parts that are different from those in Embodiment 3 will be described, and the same components will be marked with the same symbols and the description will be omitted.

[0096] The spring component 1H of this embodiment 6 includes: nine disc springs 2, and connecting portions (first connecting portions) 3, 3E, and 3K that connect adjacent disc springs 2 to each other.

[0097] The connecting part 3K is strip-shaped and connects the nine disc springs 2 that are adjacent to each other in the column direction, that is, the disc springs 2 that are different from the disc springs 2 connected to the connecting part 3E. Similar to the connecting parts 3 and 3E, the connecting part 3K extends in a bent manner and is connected to two disc springs 2 at each of its two ends.

[0098] The spring component 1H is formed into a closed loop based on the disc spring 2 and the connecting parts 3, 3E, and 3K.

[0099] Similar to Embodiment 3, in Embodiment 6, the connecting portions 3, 3E, and 3K that link the disc springs 2 together are partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portions 3, 3E, and 3K when the spring component 1H is subjected to a load. According to Embodiment 6, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portions.

[0100] Furthermore, according to embodiment 6, the spring component 1H is formed into a closed loop shape based on the disc spring 2 and the connecting portions 3, 3E, and 3K, so the relative positional relationship of the disc spring 2 can be maintained compared to the spring component 1E.

[0101] Implementation Method 7 Next, refer to Figure 15 This embodiment 7 will be described. Figure 15This is a top view showing the structure of the spring component according to Embodiment 7 of the present invention. Compared with the spring component 1 of Embodiment 1, this Embodiment 7 includes twenty-four disc springs 2 and multiple connecting portions 3, 3L. Hereinafter, the parts that differ from Embodiment 1 will be described, and the same components will be labeled with the same symbols and the description will be omitted.

[0102] The spring component 1I of this embodiment 7 includes: twenty-four disc springs 2, and connecting portions (first connecting portions) 3, 3L that connect adjacent disc springs 2 to each other. The twenty-four disc springs 2 are formed into a three-layer ring structure arranged on the circumference of a concentric circle composed of an inner circumference, an outer circumference, and a middle portion. Four disc springs 2 are arranged in the inner circumference, eight disc springs 2 are arranged in the middle portion, and twelve disc springs 2 are arranged in the outer circumference. In each portion, the disc springs 2 are arranged at equal intervals in the circumferential direction, for example.

[0103] The connecting part 3 connects the disc springs 2 that are adjacent to each other in the circumferential direction of each part. Multiple connecting parts 3 are provided. For example, the disc spring 2 located on the outer periphery is connected to the disc spring 2 adjacent to one side in the circumferential direction via the connecting part 3, while the disc spring 2 adjacent to the other side in the circumferential direction is connected via a connecting part 3 that is different from the connecting part 3 connected to the disc spring 2 on one side.

[0104] The connecting portion 3L is strip-shaped, connecting adjacent annular disc springs 2 among the plurality of disc springs 2. Similar to the connecting portion 3, the connecting portion 3L extends in a bent manner, connecting to two disc springs 2 at each end. This embodiment 7 provides four connecting portions 3L. Furthermore, Figure 15 The image shows an example in which the farthest disc spring 2 is connected by a connecting part 3L in a ring structure, but the placement of the connecting part 3L is not limited to this example. Figure 15 In the example shown, the number of connecting parts 3L is not limited to four.

[0105] Similar to Embodiment 1, in Embodiment 7, the connecting portions 3 and 3L that link the disc springs 2 together are partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portions 3 and 3L when the spring component 1I is subjected to a load. According to Embodiment 7, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portions.

[0106] Implementation Method 8 Next, refer to Figure 16 This embodiment 8 will be described. Figure 16This is a top view showing the structure of the spring component according to Embodiment 8 of the present invention. In this Embodiment 8, the disc springs 2 are arranged in a spiral shape that moves away from the center as they rotate. In this spiral shape, the connecting part 3 connects adjacent disc springs 2 to each other in the direction of rotation. 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.

[0107] The spring component 1J of this embodiment 8 includes: twenty-three disc springs 2, and a connecting portion 3 that connects adjacent disc springs 2 to each other. The twenty-three disc springs 2 are arranged on a spiral virtual line that moves away from the center as they rotate.

[0108] The connecting part 3 connects the disc springs 2 that are adjacent to each other in the direction of rotation among the plurality of disc springs 2. Multiple connecting parts 3 are provided.

[0109] Similar to Embodiment 1, in Embodiment 8, the connecting portion 3 that links the disc springs 2 to each other is partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portion 3 when the spring component 1J is subjected to a load. According to Embodiment 8, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portion.

[0110] Implementation Method 9 Next, refer to Figure 17 This embodiment 9 will be described. Figure 17 This is a top view showing the structure of the spring component according to Embodiment 9 of the present invention. Compared with the spring component 1 of Embodiment 1, this Embodiment 9 includes sixteen disc springs 2, and multiple connecting portions 3, 3M, and a base 4. Hereinafter, the parts that differ from Embodiment 1 will be described, and the same components will be labeled with the same symbols and the description will be omitted.

[0111] The spring component 1K of this embodiment 9 includes: sixteen disc springs 2, a connecting portion 3 that connects adjacent disc springs 2 to each other, a connecting portion 3M that connects disc springs 2 to a base portion 4, and a frame-shaped base portion 4 that surrounds the disc springs 2 and the connecting portions 3 and 3M.

[0112] The connecting part 3 connects the sixteen disc springs 2 that are adjacent to each other in the row direction. Multiple connecting parts 3 are provided, for example, in multiple disc springs 2 such as... Figure 17In the case of a 4×4 row and column arrangement, the disc spring 2 located in the second column of the first row is connected to the disc spring 2 located in the first column of the first row via a connecting part 3, and is connected to the disc spring 2 located in the third column of the first row via a connecting part 3 that is different from the connecting part 3 connected to the disc spring 2 located in the first column of the first row.

[0113] In this embodiment 9, the connecting portions 3 in the same column are configured to extend in the same direction.

[0114] The frame of the base 4 houses sixteen disc springs 2 and multiple connecting parts 3 and 3M.

[0115] The second connecting part, namely the connecting part 3M, extends in a strip shape in the direction intersecting the row direction, connecting the disc spring 2 located at the end in the row direction to the base 4. Figure 17 The example shown is of a connecting portion 3M extending in a straight line, but it can also extend in a partially bent manner, similar to connecting portion 3. In this embodiment 9, eight connecting portions 3M are provided.

[0116] Similar to Embodiment 1, in Embodiment 9, the connecting portion 3 that links the disc springs 2 to each other is partially bent. This increases the number of disc springs 2 per unit area and reduces the bending stress applied to the connecting portion 3 when the spring component 1K is subjected to a load. According to Embodiment 9, the spring component can press the object with a uniform pressing load while mitigating the stress applied to the connecting portion.

[0117] Furthermore, according to this embodiment 9, all disc springs 2 are connected to the base 4 via connecting portions 3 and 3M, thus maintaining the relative positional relationship of the disc springs 2. Additionally, by fixing the base 4 to the installation position using screws or similar fixing methods, a uniform pressing load can be applied to the object, while simultaneously mitigating stress acting on the connecting portions, and reliably suppressing positional displacement of the disc springs 2 at the installation position.

[0118] Furthermore, in Embodiment 9, an example is described where each row of disc springs 2 is connected to the base 4 via connecting portion 3M. However, it is acceptable as long as all disc springs 2 are connected to the base 4 via other disc springs 2 or connecting portions 3, etc. For example, it is also possible to connect the disc springs 2 between columns as in connecting portion 3D, and connect the disc springs 2 at the ends of the disc spring group connected via connecting portions 3 and 3D to the base 4 via connecting portion 3M. In addition, an example is shown where the base 4 is a closed ring-shaped frame, but it is also possible for it to be a partially open ring-shaped (C-shaped, etc.) shape that surrounds the frame.

[0119] The foregoing has described the methods for implementing the present invention, but the present invention should not be limited to the embodiments described above. Furthermore, in the embodiments and variations, examples of L-shaped, arc-shaped, or U-shaped connecting portions have been described, but zig-shaped or similar shapes can also be used, as long as the shape is partially curved. Additionally, the case where the disc spring 2 is a hollow frustum-shaped cone has been described, but a hollow frustum-shaped pyramid or similar shape can also be used, as long as it is a frustum-shaped cone and can be deformed.

[0120] Furthermore, in the embodiments 1 to 9 and their variations described above, an example was given where the thickness of the connecting portion was the same as the thickness of the disc spring 2, but different thicknesses are also possible. For example, in order to facilitate deformation under applied stress, its thickness may be thinner than that of the disc spring 2.

[0121] 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.

[0122] Industrial applicability As described above, the spring component of the present invention is suitable for pressing an object with a uniform pressing load and for easing the stress applied to the connection.
