CN-122003554-A - Spring component

Abstract

The spring member of the present invention is disposed between two pressed bodies, and applies pressure to the pressed bodies. The spring member includes a support portion, a plurality of spring portions having a strip shape with a part thereof being curved in an arc shape, and a plurality of first connection portions extending in a first direction, respectively, for connecting the support portion and the spring portions. The support portion and the plurality of first connection portions are located on the same plane parallel to the first direction. Among the plurality of spring portions, two spring portions closest to each other are arranged so as to overlap each other partially in a first direction and a second direction orthogonal to each other in a plane.

Claims (6)

1. 1. A spring member disposed between two pressed bodies for applying pressure to the pressed bodies, the spring member comprising: A support section; a plurality of spring portions having a strip shape with a part bent into an arc shape, and A plurality of first connection portions extending in a first direction, respectively, for connecting the support portion and the spring portion, The supporting portion and the plurality of first connecting portions are located on the same plane parallel to the first direction, Among the plurality of spring portions, the spring portions closest to each other are arranged so as to overlap each other in part in the first direction and in part in the second direction, and the second direction is orthogonal to the first direction in the plane.
2. 2. The spring member according to claim 1, further comprising: and a second connecting portion for connecting the spring portions adjacent in the first direction to each other.
3. 3. A spring member according to claim 2, wherein, The spring portion has: A base portion connected to the support portion, the first connection portion, or the second connection portion; A first bending part rising upward from one end of the base in the first direction and extending relative to the plane, and A first end portion extending from an end portion of the first bending portion on the opposite side from the base portion side in a bent form opposite to the first bending portion.
4. 4. A spring member according to claim 3, wherein, The spring portion further has: A second bending portion which is raised from an end portion of the base portion on the opposite side to the first bending portion side, and extends toward the same side as the side on which the first bending portion is raised with respect to the plane, and A second end portion extending from an end portion of the second bending portion on the opposite side from the base portion side in a bent form opposite to the second bending portion.
5. 5. A spring member according to claim 3 or 4, characterized in that, The length of the first curved portion in the first direction gradually decreases from the base portion toward the first end portion.
6. 6. The spring member of claim 4 wherein the spring member is configured to move between the first and second positions, The length of the first curved portion in the first direction gradually decreases from the base portion toward the first end portion, The length of the second curved portion in the first direction gradually decreases from the base portion toward the second end portion.

Description

Spring component Technical Field The present invention relates to spring components. Background A spring member is known which is provided between a first pressed body and a second pressed body and applies pressure to one or both of them (for example, see patent document 1). The spring member described in patent document 1 is provided with a plurality of spring tongues formed by bending, cutting, and tilting a part of a plate-like member, and the spring tongues are pressed against one pressed body and apply a load thereto. Patent document 1 Japanese patent laid-open publication No. 2005-302729. Disclosure of Invention However, depending on the application, miniaturization of the spring member is sometimes demanded. However, if the number of spring tongues is reduced in order to achieve miniaturization, the load applied to the pressed body by the spring member is reduced. The present invention has been made in view of the above-described problems, and an object thereof is to provide a spring member that can be miniaturized while suppressing a decrease in load applied to a pressed body. In order to solve the above problems and achieve the object, the present invention provides a spring member disposed between two pressed bodies for applying pressure to the pressed bodies, the spring member including a support portion, a plurality of spring portions each having a strip shape with a part thereof curved in an arc shape, and a plurality of first connection portions each extending in a first direction for connecting the support portion and the spring portions, the support portion and the plurality of first connection portions being located on the same plane parallel to the first direction, wherein the spring portions closest to each other among the plurality of spring portions are disposed so as to partially overlap each other in the first direction and the second direction, and the second direction is orthogonal to the first direction on the plane. In the spring member according to the present invention, the spring member further includes a second connecting portion for connecting the spring portions adjacent to each other in the first direction. In the above-described invention, the spring member may include a base portion connected to the support portion, the first connection portion, or the second connection portion, a first bending portion that extends upward from one end of the base portion in the first direction with respect to the plane, and a first end portion that extends in a bent shape opposite to the first bending portion from an end portion of the first bending portion opposite to the base portion side. In the spring member according to the present invention, the spring portion further includes a second bent portion that extends from an end portion of the base portion on the opposite side of the first bent portion to the same side as the side on which the first bent portion is raised with respect to the plane, and a second end portion that extends from an end portion of the second bent portion on the opposite side of the base portion in a bent shape opposite to the second bent portion. In the spring member according to the present invention, the length of the first bending portion in the first direction gradually decreases from the base portion toward the first end portion. In the spring member according to the present invention, the length of the first bending portion in the first direction gradually decreases from the base portion toward the first end portion, and the length of the second bending portion in the first direction gradually decreases from the base portion toward the second end portion. According to the present invention, the load applied to the pressed body can be reduced while the reduction in size is suppressed.
