[0006] Patent Document 1: Japanese Patent No. 5703737 Summary of the Invention

[0007] The problem the invention aims to solve

[0008] However, the conventional spring components have the following problems: the spring constant cannot be different at multiple positions along the plane orthogonal to the first direction, which can easily limit the structure and type of products that can be made to use the spring components.

[0009] This invention was made in consideration of this problem, and its purpose is to provide a spring component that can vary the spring constant between multiple positions along a plane orthogonal to a first direction.

[0010] Solution for solving the problem

[0011] To achieve this objective and solve the aforementioned problem, the spring component of the first aspect of the present invention is a spring component disposed between a pair of mutually opposing pressed bodies in a first direction, and includes a plurality of base plate portions stacked along the first direction. A plurality of spring tabs are formed on each of the base plate portions, and the plurality of spring tabs protrude toward either of the pair of pressed bodies and apply force to the pair of pressed bodies in a direction opposite to each other along the first direction. A through hole is formed on the base plate portion of one of the two adjacent base plate portions in the first direction, located near the pressed body of that portion. The through hole passes through the spring tab of the other base plate portion in a through-hole manner along the first direction. At least a portion of the portions where the spring tabs are provided have a different spring constant than the spring constants of the other portions in a plane orthogonal to the first direction.

[0012] According to this first aspect, since at least a portion of the multiple locations where spring tabs are provided along the surface direction of a plane orthogonal to the first direction have different spring constants than the spring constants of other locations, it is possible to obtain a spring component with different spring constants at multiple locations along the surface direction.

[0013] Because it has multiple substrate portions stacked along the first direction, it is easy to expand the selection range of physical property values ​​such as Young's modulus of multiple spring tabs, and it makes it difficult to impose structural or type limitations on products that can be used with spring components.

[0014] The spring component of the second aspect of the present invention is a spring component disposed between a pair of pushable bodies facing each other in a first direction, and having a base plate portion with its front and back facing the first direction. A plurality of spring tabs are formed on the base plate portion, the plurality of spring tabs protruding along the first direction and applying force to the pair of pushable bodies in a direction opposite to each other along the first direction. The thickness of at least a portion of the plurality of spring tabs is different from the thickness of the other spring tabs.

[0015] According to the second aspect, since the thickness of at least a portion of the spring tabs is different from the thickness of the other spring tabs, it is easy to obtain spring components with different spring constants at multiple positions along the surface direction.

[0016] In the first aspect, it is also possible that the volume of the spring tabs disposed in one portion of the plurality of spring tabs formed in at least one of the plurality of substrate portions is different from the volume of the spring tabs disposed in the other portions.

[0017] In this case, since the volume of the spring tabs differs among the multiple spring tabs formed on the substrate portion, the spring tabs located at a certain portion and the spring tabs located at other portions, it is easy to obtain spring components with different spring constants at multiple locations along the surface direction.

[0018] In the first aspect, the number of spring tabs located in one part may be different from the number of spring tabs located in the other parts, and multiple spring tabs located in the same part may be stacked along the first direction.

[0019] In this case, since the number of spring tabs in at least some of the multiple locations where spring tabs are provided is different from the number of spring tabs in other locations along the surface direction, it is easy to obtain a spring component with different spring constants at multiple locations along the surface direction.

[0020] In the first aspect, it is also possible that the Young's modulus of the material forming at least one of the plurality of substrate portions is different from the Young's modulus of the material forming the other substrate portions.

[0021] In this case, since the Young's modulus of the material forming at least one of the multiple substrate portions is different from the Young's modulus of the material forming the other substrate portions, it is easy to obtain a spring component with different spring constants at multiple locations along the surface direction.

[0022] In the first aspect, at least a portion of the portion of the substrate that abuts against the pushed body may be electrically insulated relative to the pushed body, and in the electrically insulated state, force may be applied to the pair of pushed bodies in a direction that is opposite to each other along the first direction.

[0023] In this case, since force is applied to a pair of pressed bodies in an electrically insulating state in a direction that is opposite to each other along a first direction, a spring component suitable for products requiring electrical insulation between a pair of pressed bodies can be obtained.

[0024] Invention Effects

[0025] According to the invention, the spring constant can be made different at multiple positions along the surface direction of a plane orthogonal to the first direction. Attached Figure Description

[0043] Hereinafter, a first embodiment of the spring component of the present invention will be described with reference to the accompanying drawings.

[0044] like Figure 1A as well as Figure 1B As shown, the spring member 1 of this embodiment is disposed between a pair of pressing bodies W1 and W2 that are opposed to each other in the first direction Z. The spring member 1 includes a plurality of base plate portions 11a and 11b stacked along the first direction Z. The base plate portions 11a and 11b are disposed with their respective front and back sides facing the first direction Z. The base plate portions 11a and 11b that are adjacent to each other in the first direction Z are fixed to each other by means of, for example, welding, riveting, a frame, pins, or fastening members. The base plate portions 11a and 11b are formed of, for example, carbon steel or stainless steel.

[0045] Furthermore, the substrate portions 11a and 11b that are adjacent to each other in the first direction Z can also be positioned relative to each other in the direction along the surface of a plane orthogonal to the first direction Z (i.e., in a direction parallel to the plane or in a direction orthogonal to the first direction Z) using a frame or pin.

[0046] Multiple spring tabs 12 are formed in each substrate portion 11a, 11b. The multiple spring tabs 12 protrude toward either of a pair of pushed bodies W1, W2 and apply force to the pair of pushed bodies W1, W2 in a direction that is opposite to each other along the first direction Z.

[0047] One end of the spring tab 12 (hereinafter referred to as the base end 12a) is a fixed end connected to the base plate portions 11a and 11b (the portion of the base plate portions 11a and 11b along the surface direction), and the other end (hereinafter referred to as the front end 12b) is a free end and cantilevered.

[0048] Viewed from the first direction Z, the spring tab 12 is a rectangle with four sides. Viewed from the first direction Z, the spring tab 12 is a rectangle in which opposite sides of the four sides are of equal length. Alternatively, the spring tab 12 may also be trapezoidal or the like when viewed from the first direction Z.

[0049] One of the four side portions is designated as a base end portion 12a connected to the base plate portions 11a and 11b, and the other side opposite the base end portion 12a is designated as a front end portion 12b. The spring tab 12 extends from the base end portion 12a toward the front end portion 12b toward the one being pushed. In other words, the spring tab 12 extends obliquely in one of the following directions: a direction parallel to the first direction Z and toward the one being pushed, and a direction along the surface direction. Figure 1BAs shown, the front and back surfaces of the spring tab 12 extend in a straight line from the base end 12a toward the front end 12b. Alternatively, the front and back surfaces of the spring tab 12 may extend in a curved line from the base end 12a toward the front end 12b.

[0050] The plurality of spring tabs 12 formed on the substrate portions 11a and 11b extend in the same direction from the base end portion 12a toward the front end portion 12b along the surface direction of a plane orthogonal to the first direction Z. This direction is also the same in the substrate portions 11a and 11b.

[0051] Hereinafter, the direction orthogonal to the base end portion 12a and the front end portion 12b of the spring protrusion 12 along the surface direction will be referred to as the second direction X, and the direction along the base end portion 12a and the front end portion 12b of the spring protrusion 12 will be referred to as the third direction Y.

[0052] The spring tabs 12 are provided in multiple locations at equal intervals along the second direction X, and also in multiple locations at equal intervals along the third direction Y. In this embodiment, the intervals in the second direction X and the intervals in the third direction Y are different from each other, but they can also be equal.

[0053] Furthermore, the spacing between the second direction X and the third direction Y can be made uneven, or they can be made different from each other in the substrate portions 11a and 11b.

[0054] The plurality of spring tabs 12 formed on the substrate portions 11a and 11b protrude in the same direction along the first direction Z. This direction is also the same in the substrate portions 11a and 11b. Figure 1B As shown, multiple spring tabs 12 protrude toward the first of a pair of pushed bodies W1 and W2, namely the first pushed body W1.

[0055] Alternatively, some of the spring protrusions 12 in the substrate portions 11a and 11b, which are formed among the plurality of spring protrusions 12 in each substrate portion, may be made to protrude in opposite directions to the other spring protrusions 12 in the first direction Z.

[0056] The front ends 12b of the plurality of spring tabs 12 formed on each of the substrate portions 11a and 11b are positioned identically in the first direction Z. Alternatively, the positions of these front ends 12b in the first direction Z may be different.

[0057] The tilt angles of the plurality of spring tabs 12 formed on the substrate portions 11a and 11b relative to the first direction Z are identical. These tilt angles are also identical in the substrate portions 11a and 11b. Alternatively, the tilt angle of at least a portion of the spring tabs 12 formed on each substrate portion 11a and 11b may be different from the tilt angle of the other spring tabs 12.

[0058] In the first substrate portion 11a, which is located near the first pushed body W1, one of the two adjacent substrate portions 11a and 11b in the first direction Z, a plurality of first insertion holes 13 are formed. The first insertion holes 13 are inserted through the spring tabs 12 of the other second substrate portion 11b in a state of penetrating along the first direction Z.

[0059] The first insertion hole 13 is provided in each of the substrate portions 11a and 11b at all positions opposite to the plurality of spring tabs 12 in the first direction Z. The size of the first insertion hole 13 in each of the substrate portions 11a and 11b is greater than or equal to the size of the spring tab 12 opposite to the first insertion hole 13 in the first direction Z. In this embodiment, the spring tabs 12 and the first insertion hole 13 are formed by stamping.

[0060] Along the surface direction, at all locations where spring tabs 12 are provided, the spring tabs 12 formed on the two substrate portions 11a and 11b are stacked along the first direction Z. The central portions of the third direction Y among the spring tabs 12 stacked along the first direction Z are aligned with each other.

[0061] Furthermore, in the spring component 1 of this embodiment, in the surface direction, the spring constant of at least a portion of the plurality of portions where spring tabs 12 are provided is different from the spring constant of other portions R2. The volume of the spring tabs 12 differs from that of the plurality of spring tabs 12 formed on each of the substrate portions 11a, 11b. In other words, the volume of the spring tab 12 provided on portion R1 of the plurality of spring tabs 12 formed on at least one substrate portion (substrate portion 11b in this embodiment) of the plurality of substrate portions 11a, 11b is different from the volume of the other spring tabs 12 provided on portion R2. At least one of the length, width, and thickness of the spring tab 12 differs from that of the plurality of spring tabs 12 formed on each of the substrate portions 11a, 11b. In other words, at least one of the length, width, and thickness of the spring tab 12 provided in portion R1 among the plurality of spring tabs 12 formed in the plurality of substrate portions 11a, 11b (substrate portion 11b in this embodiment) is different from the other spring tabs 12 provided in portion R2.

[0062] Alternatively, by making the external dimensions such as length, width, and thickness of the multiple spring tabs 12 formed on each of the substrate portions 11a and 11b the same, a through hole is formed in the spring tab 12 through the thickness direction, so that the volume of the spring tab 12 is different from that of the other spring tabs among the multiple spring tabs 12 formed on each of the substrate portions 11a and 11b.

[0063] like Figure 1A as well as Figure 1B As shown, the plurality of spring tabs 12 formed in the first substrate portion 11a, located near the first pressed body W1, are formed to the same size (volume). The width (third-direction Y-axis size) of the spring tab 12 located in the central region (including portion R1) of the second substrate portion 11b is narrower than the width of the spring tab 12 located at the outer periphery (including portion R2) of the second substrate portion 11b. In other words, the width and volume of the spring tab 12 located in a portion R1 of the second substrate portion 11b are smaller than the width and volume of the other spring tabs 12 located in portion R2.

[0064] The width of the spring tab 12 located at the outer periphery of the second substrate portion 11b is the same as the width of the spring tab 12 formed on the first substrate portion 11a. The lengths of the plurality of spring tabs 12 formed on the two substrate portions 11a and 11b are equal, and the thicknesses of the plurality of spring tabs 12 formed on the two substrate portions 11a and 11b are equal. The two substrate portions 11a and 11b are formed of the same material. The thicknesses of the two substrate portions 11a and 11b are the same.

[0065] According to the above description, in the direction along the surface, the spring constant of each part of the spring member 1 located on the outer periphery of the spring member 1 is higher than the spring constant of each part located in the central region of the spring member 1 in the direction along the surface.

[0066] As explained above, according to the spring component 1 of this embodiment, since at least a portion of the multiple locations where the spring protrusion 12 is provided in the surface direction have different spring constants than the spring constants of other locations, it is possible to obtain a spring component 1 with different spring constants at multiple locations in the surface direction.

[0067] Because it has multiple substrate portions 11a and 11b stacked along the first direction Z, it is easy to expand the range of selection of physical property values ​​such as Young's modulus of the multiple spring tabs 12, and it is difficult to impose structural or type restrictions on products that can be used with the spring component 1.

[0068] Since the volume of the spring tab 12 is different from that of the multiple spring tabs 12 formed in each of the substrate portions 11a, 11b, at least a portion of the spring tabs 12 are different from the other spring tabs 12, it is easy to obtain a spring component 1 with different spring constants at multiple positions in the surface direction.

[0069] Below, refer to Figure 2A as well as Figure 2B This describes the spring component 2 according to the second embodiment of the present invention.

[0070] Furthermore, in this second embodiment, the same reference numerals are used for the parts that are the same as those in the first embodiment, and their descriptions are omitted; only the differences are described.

[0071] In the spring component 2 of this embodiment, a plurality of spring tabs 12 formed on the first substrate portion 11a are formed to be of the same size (volume), and the length (size in the second direction X) of a portion of the plurality of spring tabs 12 formed on the second substrate portion 11b is different from the length of the other spring tabs 12. For example Figure 2A as well as Figure 2BAs shown, the length of the spring tab 12 located in the central region (including portion R1) along the surface direction in the second substrate portion 11b is shorter than the length of the spring tab 12 located in the outer peripheral portion (including portion R2) of the second substrate portion 11b.

[0072] The length of the spring tab 12 located at the outer periphery of the second substrate portion 11b is the same as the length of the spring tab 12 formed on the first substrate portion 11a. The widths of the plurality of spring tabs 12 formed on the two substrate portions 11a and 11b are equal, and the thicknesses of the plurality of spring tabs 12 formed on the two substrate portions 11a and 11b are equal.

[0073] According to the above description, in the spring component 2, the spring constant of each part of the outer periphery of the spring component 2 where the spring tab 12 is provided in the surface direction is lower than the spring constant of each part of the central region in the surface direction of the spring component 2.

[0074] As explained above, according to the spring component 2 of this embodiment, since at least a portion of the spring protrusions 12 formed on each of the multiple spring protrusions 12 in the respective substrate portions 11a, 11b are different from each other, it is easy to obtain a spring component 2 with different spring constants at multiple positions in the surface direction.

[0075] Below, refer to Figure 3A as well as Figure 3B This describes the spring component 3 according to the third embodiment of the present invention.

[0076] Furthermore, in this third embodiment, the same reference numerals are used for the parts that are the same as those in the first embodiment, and their descriptions are omitted; only the differences are described.

[0077] In the spring component 3 of this embodiment, the plurality of spring tabs 12 formed on the first substrate portion 11a are formed to be of the same size, and the thickness of a portion of the plurality of spring tabs 12 formed on the second substrate portion 11b is different from the thickness of the other spring tabs 12. For example Figure 3A as well as Figure 3B As shown, the thickness of the spring tab 12 located in the central region (including portion R1) along the surface direction in the second substrate portion 11b is thinner than the thickness of the spring tab 12 located in the outer peripheral portion (including portion R2) of the second substrate portion 11b.

[0078] The thickness of the spring tab 12 located at the outer periphery of the second substrate portion 11b is the same as the thickness of the spring tab 12 formed on the first substrate portion 11a. The lengths of the plurality of spring tabs 12 formed on the two substrate portions 11a and 11b are equal, and the widths of the plurality of spring tabs 12 formed on the two substrate portions 11a and 11b are equal.

[0079] According to the above description, in the spring component 3, the spring constant of each part of the outer periphery of the spring component 3 among the multiple parts of the spring tab 12 provided in the surface direction is higher than the spring constant of each part of the central region in the surface direction of the spring component 3.

[0080] like Figure 3B As shown, the thickness of the first substrate portion 11a is the same throughout the entire area. The thickness of the central region of the second substrate portion 11b in the surface direction is thinner than the thickness of the outer peripheral portion of the second substrate portion 11b. The thickness of the outer peripheral portion of the second substrate portion 11b is the same as the thickness of the first substrate portion 11a.

[0081] A recess 11c is formed in the central region along the surface direction of the surface of the second substrate portion 11b, on both the front and back sides, facing the second pressed body W2 of the pair of pressed bodies W1 and W2. The thickness of the central region along the surface direction in the second substrate portion 11b is thinner than the thickness of the outer periphery of the second substrate portion 11b. The recess 11c is formed by, for example, etching, cutting, or stamping. In this embodiment, the plurality of spring tabs 12 are formed by stamping after the recess 11c is formed.

[0082] Furthermore, if work hardening occurs during the formation of the recess 11c, and the central region in the surface direction of the second substrate portion 11b becomes hard, then sometimes the spring constant of each of the multiple locations where the spring tabs 12 are provided in the surface direction, the location on the outer periphery of the spring member 3, is lower than the spring constant of each location in the central region in the surface direction of the spring member 3.

[0083] The recess 11c may also be formed on the front and back surfaces of the second substrate portion 11b, facing the first pushed body W1 of the pair of pushed bodies W1 and W2.

[0084] As explained above, according to the spring component 3 of this embodiment, since the thickness of the spring tabs 12 is different from that of the other spring tabs 12 among the plurality of spring tabs 12 formed in each of the substrate portions 11a, 11b, it is easy to obtain a spring component 3 with different spring constants at multiple positions in the surface direction.

[0085] Below, refer to Figure 4A as well as Figure 4B The spring component 4 of the fourth embodiment of the present invention will be described.

[0086] Furthermore, in this fourth embodiment, the same reference numerals are used for the parts that are the same as those in the first embodiment, and their descriptions are omitted; only the differences are described.

[0087] In the spring component 4 of this embodiment, a plurality of spring tabs 12 formed on each of the substrate portions 11a and 11b are formed to the same size. In the second substrate portion 11b, a plurality of spring tabs 12 are formed only on the outer peripheral portion (including portion R2), and no spring tabs 12 are formed in the central region (including portion R1) in the surface direction, and the central region in the surface direction is formed flat.

[0088] Therefore, in the surface direction, the number of spring tabs 12 located at the outer periphery of the spring member 4 among the multiple locations where spring tabs 12 are provided is greater than the number of spring tabs 12 located in the central region of the spring member 4 in the surface direction. That is, in the surface direction, the number of spring tabs 12 located at least a portion of the multiple locations where spring tabs 12 are provided is different from the number of spring tabs 12 located in other locations.

[0089] like Figure 4B As shown, each location on the outer periphery of the spring member 4 has two spring tabs 12, and these spring tabs 12 are stacked in the first direction Z. Each location on the central region along the surface direction of the spring member 4 has one spring tab 12. That is, in location R2, the two spring tabs 12 of the substrate portions 11a and 11b are stacked on top of each other, while in location R1, only the spring tab 12 of the substrate portion 11a is provided.

[0090] According to the above description, in the direction along the surface, the spring constant of each part of the spring member 4 located on the outer periphery of the spring protrusion 12 is higher than the spring constant of each part of the central region of the spring member 4 located in the direction along the surface.

[0091] As explained above, according to the spring component 4 of this embodiment, since the number of spring tabs 12 located in at least a portion of the multiple locations where spring tabs 12 are provided in the surface direction is different from the number of spring tabs 12 located in other locations, it is easy to obtain a spring component 4, etc., with different spring constants between multiple locations in the surface direction.

[0092] Below, refer to Figure 5A as well as Figure 5B This describes the spring component 5 according to the fifth embodiment of the present invention.

[0093] Furthermore, in this fifth embodiment, the same reference numerals are used for the parts that are the same as those in the first embodiment, and their descriptions are omitted; only the differences are described.

[0094] In the spring component 5 of this embodiment, the multiple spring tabs 12 formed on each of the substrate portions 11a and 11b are formed to be the same size.

[0095] In the first substrate portion 11a, a plurality of spring tabs 12 are formed only at the outer peripheral edge, and a second through hole 14 is formed in the central region along the surface direction. The second through hole 14 is larger than the spring tabs 12 formed in the second substrate portion 11b. In the second substrate portion 11b, a plurality of spring tabs 12 are formed only in the central region along the surface direction, and no spring tabs 12 are formed at the outer peripheral edge, which is formed flat.

[0096] A plurality of spring tabs 12 formed on the second substrate portion 11b are inserted through the second insertion hole 14 of the first substrate portion 11a in a through-hole state along the first direction Z. All of the plurality of spring tabs 12 formed on each substrate portion 11a, 11b abut against the first pushed body W1. The length of the spring tab 12 formed on the second substrate portion 11b is longer than the length of the spring tab 12 formed on the first substrate portion 11a. Alternatively, the former may be the same length as the latter.

[0097] In the surface direction, the number of spring tabs 12 located at each of the portions where spring tabs 12 are provided is one. The Young's modulus of the material forming the first substrate portion 11a is different from the Young's modulus of the material forming the second substrate portion 11b. That is, the Young's modulus of the material forming at least one of the plurality of substrate portions 11a, 11b is different from the Young's modulus of the materials forming the other substrate portions.

[0098] According to the above description, the spring constant of each part of the spring member 5 located on the outer periphery of the spring protrusion 12 in the surface direction is different from the spring constant of each part located in the central region of the spring member 5 in the surface direction.

[0099] Furthermore, in order to make the Young's modulus of the materials different in the first substrate portion 11a and the second substrate portion 11b, in addition to making the materials themselves different, the same materials can also have different conditions, such as the presence or absence of heat treatment, or heat treatment conditions.

[0100] As explained above, according to the spring component 5 of this embodiment, since the Young's modulus of the material of at least one of the plurality of substrate portions 11a, 11b is different from the Young's modulus of the material of the other substrate portions, it is easy to obtain a spring component 5 with different spring constants at multiple positions along the surface direction.

[0101] Below, refer to Figure 6 This describes the spring component 6 according to the sixth embodiment of the present invention.

[0102] Furthermore, in this sixth embodiment, for the relationship with... Figure 5A as well as Figure 5B In the fifth embodiment shown, the same structural elements are labeled with the same reference numerals, and their descriptions are omitted; only the differences are described.

[0103] In the spring component 6 of this embodiment, the thickness of the plurality of spring tabs 12 formed on the second substrate portion 11b is different from the thickness of the plurality of spring tabs 12 formed on the first substrate portion 11a. The Young's modulus of the material forming the first substrate portion 11a is the same as the Young's modulus of the material forming the second substrate portion 11b.

[0104] like Figure 6 As shown, the thickness of the plurality of spring tabs 12 formed on the second substrate portion 11b is thinner than the thickness of the plurality of spring tabs 12 formed on the first substrate portion 11a. The thickness of the second substrate portion 11b is thinner than the thickness of the first substrate portion 11a.

[0105] According to the above description, in the direction along the surface, the spring constant of each part of the spring member 5 located on the outer periphery of the spring protrusion 12 is higher than the spring constant of each part of the central region of the spring member 5 located in the direction along the surface.

[0106] Furthermore, the thickness of the plurality of spring tabs 12 formed on the second substrate portion 11b may be greater than the thickness of the plurality of spring tabs 12 formed on the first substrate portion 11a. The thickness of the second substrate portion 11b may also be greater than the thickness of the first substrate portion 11a. Additionally, the Young's modulus of the material forming the first substrate portion 11a may be different from the Young's modulus of the material forming the second substrate portion 11b.

[0107] As explained above, according to the spring component 6 of this embodiment, since the thickness of the plurality of spring tabs 12 formed on the second substrate portion 11b is different from the thickness of the plurality of spring tabs 12 formed on the first substrate portion 11a, the plurality of spring tabs 12 formed on the second substrate portion 11b are inserted through the second insertion hole 14 of the first substrate portion 11a in a state of penetrating along the first direction Z, and all the plurality of spring tabs 12 formed on each substrate portion 11a, 11b abut against the first pushed body W1, it is easy to obtain a spring component 6, etc., with different spring constants at multiple positions along the surface direction.

[0108] Below, refer to Figure 7A as well as Figure 7B This describes the spring component 7 according to the seventh embodiment of the present invention.

[0109] Furthermore, in this seventh embodiment, for the relationship with... Figure 4A as well as Figure 4B In the fourth embodiment shown, the same structural elements are labeled with the same reference numerals, and their descriptions are omitted; only the differences are described.

[0110] In the spring member 7 of this embodiment, at least a portion of the portion of the base plate portions 11a and 11b that abuts against the pushed bodies W1 and W2 is electrically insulated relative to the pushed bodies W1 and W2, and in the electrically insulated state, a force is applied to the pair of pushed bodies W1 and W2 in a direction that is opposite to each other along the first direction Z.

[0111] The first substrate portion 11a is formed of an electrically insulating material, and the second substrate portion 11b is formed of a metallic material. The length (in the second direction X) of the plurality of spring tabs 12 formed on the second substrate portion 11b is shorter than the length of the spring tabs 12 formed on the first substrate portion 11a. On the first pushed body W1, which is abutted by the spring tabs 12 in a pair of pushed bodies W1 and W2, only the plurality of spring tabs 12 formed on the first substrate portion 11a abut against it, while the plurality of spring tabs 12 formed on the second substrate portion 11b are not in contact.

[0112] In addition, the first substrate portion 11a may also be formed of a metal material, and at least the spring tabs 12 in the first substrate portion 11a may be covered with an electrically insulating material.

[0113] As explained above, the spring component 7 according to this embodiment applies force to a pair of pushed bodies W1 and W2 in a direction that is opposite to each other along the first direction Z while in an electrically insulating state. Therefore, it is possible to obtain a spring component 7 or the like that suitable for products that require electrical insulation between a pair of pushed bodies W1 and W2.

[0114] Below, refer to Figure 8A as well as Figure 8BThis describes the spring component 8 according to the eighth embodiment of the present invention.

[0115] Furthermore, in this eighth embodiment, for the relationship with... Figure 5A as well as Figure 5B In the fifth embodiment shown, the same structural elements are labeled with the same reference numerals, and their descriptions are omitted; only the differences are described.

[0116] In the spring member 8 of this embodiment, at least a portion of the portion of the base plate portions 11a and 11b that abuts against the pushed bodies W1 and W2 is electrically insulated relative to the pushed bodies W1 and W2, and in the electrically insulated state, a force is applied to the pair of pushed bodies W1 and W2 in a direction that is opposite to each other along the first direction Z.

[0117] The first substrate portion 11a is formed of a metallic material, and the second substrate portion 11b is formed of an electrically insulating material. The length (size in the second direction X) of the plurality of spring tabs 12 formed on the second substrate portion 11b is longer than the length of the spring tabs 12 formed on the first substrate portion 11a. All of the plurality of spring tabs 12 formed on each of the substrate portions 11a and 11b abut against the first pushed body W1, one of the pair of pushed bodies W1 and W2, which is abutted against by the spring tabs 12. The spring tabs 12 of the first substrate portion 11a, which is formed of a metallic material, abut against the pushed body W1, but the second substrate portion 11b, which is formed of an electrically insulating material, is disposed between the first substrate portion 11a and the pushed body W2, so the pair of pushed bodies W1 and W2 are maintained in an electrically insulating state.

[0118] Furthermore, the second substrate portion 11b may also adopt a structure in which the portion formed of a metal material, at least the portion of the second substrate portion 11b that abuts against the second push-body W2 of the pair of push-body W1 and W2, is covered with an electrically insulating material.

[0119] As explained above, the spring component 8 according to this embodiment, since it applies force to a pair of pressed bodies W1 and W2 in a direction that is opposite to each other along the first direction Z while in an electrically insulating state, can be used to obtain a spring component 8 or the like that suitable for products that require electrical insulation between a pair of pressed bodies W1 and W2.

[0120] Below, refer to Figure 9A as well as Figure 9B This describes the spring component 9 according to the ninth embodiment of the present invention.

[0121] Furthermore, in this ninth embodiment, for the relationship with... Figure 3A as well as Figure 3B In the third embodiment shown, the same structural elements are labeled with the same reference numerals, and their descriptions are omitted; only the differences are described.

[0122] In the spring member 9 of this embodiment, a second base plate portion 11b is provided with its front and back sides facing the first direction Z. The spring member 9 does not include the first base plate portion 11a described in the above embodiment. At least a portion of the spring protrusions 12 formed in the second base plate portion 11b have a different thickness than the other spring protrusions 12. For example... Figure 9A as well as Figure 9B As shown, the thickness of the spring tab 12 located in the central region (including portion R1) along the surface direction of the second substrate portion 11b is thinner than the thickness of the spring tab 12 located in the outer peripheral portion (including portion R2) of the second substrate portion 11b. The thickness of the central region along the surface direction of the second substrate portion 11b is thinner than the thickness of the outer peripheral portion of the second substrate portion 11b. A recess 11c is formed in the central region along the surface direction of the second substrate portion 11b on both the front and back surfaces, facing the second pressed body W2, so that the thickness of the central region along the surface direction of the second substrate portion 11b is thinner than the thickness of the outer peripheral portion of the second substrate portion 11b. In this embodiment, the spring tab 12 is formed by stamping after the recess 11c is formed.

[0123] All of the multiple spring tabs 12 formed on the second substrate portion 11b abut against the first pushed body W1.

[0124] According to the above description, in the direction along the surface, the spring constant of each part of the spring member 9 located on the outer periphery of the spring protrusion 12 is higher than the spring constant of each part of the central region of the spring member 9 located in the direction along the surface.

[0125] Furthermore, if work hardening occurs during the formation of the recess 11c, and the central region in the surface direction of the second substrate portion 11b becomes hard, then sometimes the spring constant of each of the multiple locations where the spring tabs 12 are provided in the surface direction, the location on the outer periphery of the spring member 9, is lower than the spring constant of each location in the central region in the surface direction of the spring member 9.

[0126] The recess 11c may also be formed on the front and back surfaces of the second substrate portion 11b, facing the first pushed body W1 of the pair of pushed bodies W1 and W2.

[0127] As explained above, according to the spring component 9 in this embodiment, since the thickness of at least a portion of the spring protrusions 12 is different from the thickness of the other spring protrusions 12, it is easy to obtain a spring component 9 with different spring constants at multiple positions along the surface direction.

[0128] Furthermore, the scope of the present invention is not limited to the described embodiments, and various modifications can be made within the scope of the present invention.

[0129] In the first to eighth embodiments, three or more substrate portions may be provided. That is, in addition to substrate portions 11a and 11b, other substrate portions may also be provided.

[0130] In the embodiment described, the spring constant of each of the multiple locations where the spring tabs 12 are provided in the surface direction, the spring constant of each location located on the outer periphery of the spring member, is different from the spring constant of each location located in the central region of the spring member in the surface direction. However, this is not a limitation. For example, the spring constants of the spring tabs 12 may be different between multiple locations in the second direction X or the third direction Y, or they may be different in a serrated manner in the surface direction. These can be appropriately modified.

[0131] The spring tab 12 can also be structured in the following way: for example, front ends 12b are provided on both sides of the base end 12a along the second direction X, and are V-shaped or U-shaped when viewed from the third direction Y. In other words, the protruding directions of two adjacent spring tabs 12 in the second direction X can also be opposite to each other.

[0132] Alternatively, at least a portion of the spring tabs 12 formed on the substrate portions 11a and 11b may extend in different directions from the base end portion 12a toward the front end portion 12b in the surface direction compared to the other spring tabs 12.

[0133] In this structure, the following structure may also be adopted: the front ends 12b of each spring tab 12 formed on the substrate portions 11a and 11b that are adjacent to each other in the first direction Z are stacked together along the first direction Z.

[0134] Furthermore, within the scope of this invention, the structural elements in the embodiments can be appropriately converted into known structural elements, and the embodiments and variations can be appropriately combined.
