Description

[Technical Field]

[0001] The present invention relates to a switch device. [Background technology]

[0002] Conventionally, there has been known a switch in which a torsion coil spring as a contact member connected to a terminal is elastically deformed by pressing a switch lever, and the movable contact of the torsion coil spring is brought into contact with another terminal, thereby electrically connecting the terminals together (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-161975 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional switches require a torsion coil spring as a contact member, as well as a switch lever to elastically deform the torsion coil spring. Furthermore, in order for the torsion coil spring to function as a contact member, the shape of the torsion coil spring becomes complex. Furthermore, the shape of the case that holds the torsion coil spring also becomes complex. For these reasons, there is a demand for an inexpensive switch with a simple structure and a small number of parts.

[0005] The present invention has been made in view of the above problems of the prior art, and has as its object to provide an inexpensive switch device with a simple structure and a small number of parts. [Means for solving the problem]

[0006] According to one aspect of the present invention, there is provided a device comprising: a base member having a first accommodating groove extending along a longitudinal direction; a first conductive member having a first contact portion exposed in the first accommodating groove; a second conductive member having a second contact portion exposed in the first accommodating groove; a cover member attached to the base member and covering the first accommodating groove, the cover member having a first boss extending from an outside to an inside of the first accommodating groove and a first opening connecting the first accommodating groove with an external space; and a conductive first spring member that is elastically deformable and has a first boss and a second opening that connects the first accommodating groove with an external space. A switch device is provided, comprising a first spring member including: a first connection portion electrically connected to one of the contact portion and the second contact portion; a first boss engagement portion extending from the first connection portion and engaging with the first boss of the cover member; a first contact portion capable of contacting an edge portion of the first opening; a first operating portion protruding from the first contact portion to the outside of the first opening; and a first movable contact portion extending from the first operating portion toward the other of the first contact portion and the second contact portion and capable of contacting the other contact portion. [Effects of the Invention]

[0007] According to the present invention, by pressing the first operating portion of the first spring member from the outside, the first spring member elastically deforms, causing the first movable contact portion to contact the contact portion, thereby electrically connecting the first conductive member and the second conductive member via the first spring member. That is, the first spring member serves both as a switch lever for elastically deforming the first spring member and as a contact member for establishing electrical connection between the two conductive members, making it possible to realize an electrical switch with a small number of parts. Furthermore, since the structures of the base member and the cover member can be simplified, it is possible to construct an inexpensive switch device with a simple structure.

[0009] Hereinafter, an embodiment of a switch device according to the present invention will be described in detail with reference to FIGS. 1 to 6B. In FIGS. 1 to 6B, identical or corresponding components are designated by the same reference numerals, and redundant description will be omitted. In addition, in FIGS. 1 to 6B, the scale and dimensions of each component may be exaggerated, and some components may be omitted. In the following description, unless otherwise specified, terms such as "first" and "second" are used merely to distinguish components from one another, and do not represent a specific order or ranking.

[0010] Fig. 1 is a perspective view showing a switch device 1 according to one embodiment of the present invention, Fig. 2 is an exploded perspective view of the switch device 1, and Fig. 3 is a plan view. As shown in Figs. 1 to 3, the switch device 1 according to this embodiment includes a base member 10, a cover member 20 removably attached to the base member 10, two spring members 30 and 40, and three conductive members 50, 60 and 70. In this embodiment, for convenience, the +Z direction in Fig. 1 will be referred to as "up" or "upper," and the -Z direction will be referred to as "down" or "lower."

[0011] As shown in FIG. 2, the base member 10 includes a substantially rectangular parallelepiped base body 11, which has two storage grooves 12A and 12B formed therein and extending along the longitudinal direction (Y direction). Storage groove 12A (first storage groove) accommodates a spring member 30 (first spring member), while storage groove 12B (second storage groove) accommodates a spring member 40 (second spring member). Base body 11 has a claw portion 13A that protrudes in the −X direction and a claw portion 13B that protrudes in the +X direction. An opening 14A is formed at the −Y end of storage groove 12A, and an opening 14B is formed at the −Y end of storage groove 12B.

[0012] The cover member 20 includes a substantially rectangular plate-shaped cover main body 21, a first side piece 22 (only one of the two first side pieces 22 is shown in FIGS. 1 and 2) extending downward (in the -Z direction) from both X-direction edge portions at approximately the center in the Y direction of the cover main body 21, second side pieces 23A, 23B extending downward from both X-direction edge portions at the -Y direction end portions of the cover main body 21, and bosses 24A, 24B extending inward from the second side pieces 23A, 23B, respectively. When the cover member 20 is attached to the base member 10, the cover main body 21 covers the storage grooves 12A, 12B of the base member 10 from above. Two openings 25A and 25B are formed in this cover body 21, and opening 25A (first opening) connects storage groove 12A to the external space, and opening 25B (second opening) connects storage groove 12B to the external space.

[0013] The first side piece 22 is elastically deformable in the X direction, and has a hook hole 26 formed in the first side piece 22. The cover member 20 is attached to the base member 10 by engaging the claws 13A, 13B of the base member 10 with the hook hole 26, respectively. The cover member 20 can be removed from the base member 10 by elastically deforming the first side piece 22 of the cover member 20 to disengage the claws 13A, 13B of the base member 10 from the hook hole 26. In this way, the cover member 20 is attached to the base member 10 in a detachable manner.

[0014] The conductive members 50, 60, and 70 are formed integrally with the base member 10 by, for example, metal powder injection molding. The conductive member 50 (first conductive member) has a terminal portion 51 to which an external lead wire is connected, an intermediate portion 52 extending from the terminal portion 51 in the -Z direction, and a flat portion 53 extending from the intermediate portion 52 in the +Y direction as a whole. The conductive member 60 (second conductive member) has a terminal portion 61 to which an external lead wire is connected, an intermediate portion 62 extending from the terminal portion 61 in the -Z direction, and a flat portion 63 extending from the intermediate portion 62 in the +Y direction as a whole. The conductive member 70 (third conductive member) has a terminal portion 71 to which an external lead wire is connected, an intermediate portion 72 extending from the terminal portion 71 in the -Z direction, and a flat portion 73 extending from the intermediate portion 72 in the +Y direction as a whole. Through holes 54, 64, 74 are formed in terminal portion 51 of conductive member 50, terminal portion 61 of conductive member 60, and terminal portion 71 of conductive member 70 to pass lead wires (not shown) connected to these conductive members 50, 60, 70, respectively. For example, the lead wires and conductive members 50, 60, 70 are connected by passing the ends of the lead wires through through holes 54, 64, 74, respectively, and then soldering the ends of the lead wires to terminal portions 51, 61, 71.

[0015] Fig. 4 is a plan view showing the conductive members 50, 60, and 70 together with the base member 10. As shown in Fig. 4, the flat plate portion 53 of the conductive member 50 has a contact portion 55 (first contact portion) exposed in the accommodating groove 12A. The flat plate portion 63 of the conductive member 60 has a contact portion 65 (second contact portion) exposed in the accommodating groove 12A and a contact portion 66 (third contact portion) exposed in the accommodating groove 12B. The flat plate portion 73 of the conductive member 70 has a contact portion 75 (fourth contact portion) exposed in the accommodating groove 12B.

[0016] The spring member 30 is made of a conductive material (for example, metal) and is intended to enable electrical connection between the conductive member 50 and the conductive member 60. The spring member 40 is made of a conductive material (for example, metal) and is intended to enable electrical connection between the conductive member 60 and the conductive member 70. These spring members 30 and 40 are both formed by bending a single plate material.

[0017] Fig. 5A is a cross-sectional view taken along line AA in Fig. 3. As shown in Fig. 5A, spring member 30 includes connection portion 31 (first connection portion) electrically connected to contact portion 65 of conductive member 60, boss engagement portion 33 (first boss engagement portion) extending to engage with boss 24A (first boss) of cover member 20, contact portion 35 (first contact portion) capable of contacting edge portion 27A of opening 25A of cover member 20, operation portion 37 (first operation portion) extending from contact portion 35 to protrude outside opening 25A, and movable contact portion 39 (first movable contact portion) extending from operation portion 37 toward contact portion 55 of conductive member 50. 5A, when the cover member 20 is attached to the base member 10, the boss 24A of the cover member 20 is positioned so as to extend in the +X direction from the outside of the accommodating groove 12A through the opening 14A (see FIG. 2), and the spring member 30 is held in the accommodating groove 12A with the boss engaging portion 33 of the spring member 30 engaged with the boss 24A. In this embodiment, the cross-sectional shape of the boss 24A of the cover member 20 in the ZY plane is oval.

[0018] 5A shows a state in which no external force is acting on spring member 30. Boss engagement portion 33 engages with boss 24A of cover member 20, and spring member 30 is held between cover member 20 and base member 10 in an elastically deformable state with movable contact portion 39 biased in a direction away from contact portion 55 of conductive member 50. In this state, contact portion 35 of spring member 30 contacts edge portion 27A of opening 25A of cover member 20, but movable contact portion 39 of spring member 30 is spaced apart from contact portion 55. At this time, height HA in the Z direction from edge portion 27A of opening 25A to top portion 36 of operating portion 37 is greater than distance GA in the Z direction between movable contact portion 39 and contact portion 55.

[0019] Fig. 5B is a cross-sectional view taken along line BB in Fig. 3. As shown in Fig. 5B, spring member 40 includes a connection portion 41 (second connection portion) electrically connected to contact portion 75 of conductive member 70, a boss engagement portion 43 (second boss engagement portion) extending to engage with boss 24B (second boss) of cover member 20, a contact portion 45 (second contact portion) capable of coming into contact with edge portion 27B of opening 25B of cover member 20, an operation portion 47 (second operation portion) extending from contact portion 45 to protrude outside opening 25B, and a movable contact portion 49 (second movable contact portion) extending from operation portion 47 toward contact portion 66 of conductive member 60. 5B, when the cover member 20 is attached to the base member 10, the boss 24B of the cover member 20 is positioned so as to extend in the −X direction from the outside of the accommodating groove 12B through the opening 14B (see FIG. 2), and the spring member 40 is held in the accommodating groove 12B with the boss engaging portion 43 of the spring member 40 engaged with the boss 24B. In this embodiment, the cross-sectional shape of the boss 24B of the cover member 20 in the ZY plane is oval.

[0020] 5B shows a state in which no external force is acting on the spring member 40. The spring member 40 is held between the cover member 20 and the base member 10 in an elastically deformable state, with the boss engagement portion 43 engaging with the boss 24B of the cover member 20, and the movable contact portion 49 being biased in a direction away from the contact portion 66 of the conductive member 60. In this state, the contact portion 45 of the spring member 40 is in contact with the edge portion 27B of the opening 25B of the cover member 20, but the movable contact portion 49 of the spring member 40 is separated from the contact portion 66. At this time, the height HB in the Z direction from the edge portion 27B of the opening 25B to the top 46 of the operating portion 47 is greater than the distance GB in the Z direction between the movable contact portion 49 and the contact portion 66.

[0021] 1, operating portion 37 of spring member 30 protrudes outward from opening 25A of cover member 20, allowing operating portion 37 to be pressed from the outside. Similarly, operating portion 47 of spring member 40 protrudes outward from opening 25B of cover member 20, allowing operating portion 47 to be pressed from the outside. The operation of pressing operating portions 37, 47 may be performed by a user, or may be performed mechanically using a drive unit (not shown).

[0022] 6A is a cross-sectional view showing a state in which spring member 30 shown in FIG. 5A is pressed. As shown in FIG. 6A, when operating portion 37 of spring member 30 is pressed from the outside, spring member 30 elastically deforms, contact portion 35 moves away from edge portion 27A of opening 25A, and movable contact portion 39 moves in the −Z direction to contact contact portion 55 of conductive member 50. In this manner, movable contact portion 39 of spring member 30 can come into contact with contact portion 55 of conductive member 50 by movement. This contact between movable contact portion 39 of spring member 30 and contact portion 55 of conductive member 50 electrically connects conductive member 60 and conductive member 50 via spring member 30.

[0023] 6A, the movable contact portion 39 of the spring member 30 includes a curved portion 38 (first curved portion). By including such a curved portion 38 in the movable contact portion 39, when the spring member 30 is further pressed from the state shown in FIG. 6A, the curved portion 38 reduces the frictional resistance that occurs when the spring member 30 comes into contact with the contact portion 55.

[0024] 6B is a cross-sectional view showing a state in which spring member 40 shown in FIG. 5B is pressed. As shown in FIG. 6B, when operating portion 47 of spring member 40 is pressed from the outside, spring member 40 elastically deforms, contact portion 45 moves away from edge portion 27B of opening 25B, and movable contact portion 49 moves in the −Z direction to contact contact portion 66 of conductive member 60. In this manner, movable contact portion 49 of spring member 40 can come into contact with contact portion 66 of conductive member 60 by movement. This contact between movable contact portion 49 of spring member 40 and contact portion 66 of conductive member 60 electrically connects conductive member 70 and conductive member 60 via spring member 40.

[0025] 6B, the movable contact portion 49 of the spring member 40 includes a curved portion 48 (second curved portion). By including such a curved portion 48 in the movable contact portion 49, when the spring member 40 is further pressed from the state shown in FIG. 6B, the curved portion 48 reduces the frictional resistance that occurs when the spring member 40 comes into contact with the contact portion 66.

[0026] Thus, according to this embodiment, switch device 1 includes base member 10 having accommodation groove 12A (first accommodation groove) extending along the longitudinal direction, conductive member 50 (first conductive member) having contact portion 55 (first connection portion) exposed in accommodation groove 12A, conductive member 60 (second conductive member) having contact portion 65 (second contact portion) exposed in accommodation groove 12A, cover member 20 attached to base member 10 to cover accommodation groove 12A, and elastically deformable conductive spring member 30 (first spring member). Cover member 20 has boss 24A (first boss) extending from the outside toward the inside of accommodation groove 12A, and opening 25A (first opening) connecting accommodation groove 12A to the outside space. The spring member 30 has a connection portion 31 (first connection portion) electrically connected to the contact portion 65 of the conductive member 60, a boss engagement portion 33 (first boss engagement portion) extending from the connection portion 31 and engaging with the boss 24A of the cover member 20, a contact portion 35 (first contact portion) capable of contacting the edge portion 27A of the opening 25A, an operating portion 37 (first operating portion) protruding from the contact portion 35 to the outside of the opening 25A, and a movable contact portion 39 (first movable contact portion) extending from the operating portion 37 toward the contact portion 55 of the conductive member 50 and capable of contacting the contact portion 55.

[0027] With this configuration, by pressing the operating portion 37 of the spring member 30 from the outside, the spring member 30 elastically deforms, causing the movable contact portion 39 to contact the contact portion 55 of the conductive member 50, thereby electrically connecting the conductive member 50 and the conductive member 60 via the spring member 30. As described above, in this embodiment, the spring member 30 serves both as a switch lever for elastically deforming the spring member 30 and as a contact member for achieving electrical connection between the two conductive members 50 and 60, making it possible to realize an electrical switch with a small number of parts. Furthermore, since the structures of the base member 10 and the cover member 20 can be simplified, it is possible to configure an inexpensive switch device 1 with a simple structure.

[0028] The base member 10 may further have a housing groove 12B (second housing groove) extending along the longitudinal direction. The conductive member 60 may further have a contact portion 66 (third contact portion) exposed in the housing groove 12B. The cover member 20 may further have a boss 24B (second boss) extending from the outside to the inside of the housing groove 12B, and an opening 25B (second opening) connecting the housing groove 12B to the external space. In this case, the switch device 1 may include a conductive member 70 (third conductive member) having a contact portion 75 (fourth contact portion) exposed in the housing groove 12B, and an elastically deformable conductive spring member 40 (second spring member). This spring member 40 may include a connection portion 41 (second connection portion) electrically connected to the contact portion 75, a boss engagement portion 43 (second boss engagement portion) extending from the connection portion 41 and engaging with the boss 24B of the cover member 20, a contact portion 45 (second contact portion) capable of contacting the edge portion 27B of the opening 25B, an operating portion 47 (second operating portion) extending from the contact portion 45 and protruding outside the opening 25B, and a movable contact portion 49 (second movable contact portion) extending from the operating portion 47 toward the contact portion 66 and capable of contacting the contact portion 66.

[0029] With this configuration, by pressing the operating portion 47 of the spring member 40 from the outside, the spring member 40 elastically deforms, bringing the movable contact portion 49 into contact with the contact portion 66 of the conductive member 60, thereby electrically connecting the conductive member 70 and the conductive member 60 via the spring member 40. In this manner, in this embodiment, the spring member 40 serves both as a switch lever for elastically deforming the spring member 40 and as a contact member for establishing electrical connection between the two conductive members 70 and 60. This allows for an electrical switch to be realized with a small number of parts. Furthermore, because the structures of the base member 10 and the cover member 20 are simple, an inexpensive switch device 1 can be constructed with a simple structure. In particular, electrical connection between the three conductive members 50, 60, and 70 can be achieved using only two spring members 30 and 40.

[0030] If the spring member 30 and the spring member 40 are each made of a single plate material, the spring member 30 and the spring member 40 can be produced simply by bending the plate material.

[0031] Furthermore, it is preferable that the movable contact portion 39 of the spring member 30 includes a curved portion 38 (first curved portion) that can come into contact with the contact portion 55, and it is preferable that the movable contact portion 49 of the spring member 40 includes a curved portion 48 (second curved portion) that can come into contact with the contact portion 66. Such curved portions 38, 48 can reduce the frictional resistance that occurs when the movable contact portions 39, 49 come into contact with the contact portions 55, 66.

[0032] When no force is applied to the spring member 30, the height HA from the edge 27A of the opening 25A to the top 36 of the operating portion 37 of the spring member 30 is preferably greater than the distance GA between the movable contact portion 39 of the spring member 30 and the contact portion 55. Similarly, when no force is applied to the spring member 40, the height HB from the edge 27B of the opening 25B to the top 46 of the operating portion 47 of the spring member 40 is preferably greater than the distance GB between the movable contact portion 49 of the spring member 40 and the contact portion 66. With this configuration, the movable contact portion 39 can be reliably brought into contact with the contact portion 55 by pushing the operating portion 37 of the spring member 30, and the movable contact portion 49 can be reliably brought into contact with the contact portion 66 by pushing the operating portion 47 of the spring member 40.

[0033] The conductive members 50, 60, 70 preferably have through holes 54, 64, 74 for passing lead wires connected to the conductive members 50, 60, 70, respectively. Forming such through holes 54, 64, 74 in the conductive members 50, 60, 70 makes it easy to fix the lead wires to the conductive members 50, 60, 70.

[0034] In the above-described embodiment, the connection portion 31 of the spring member 30 is connected to the contact portion 65 of the conductive member 60, and the movable contact portion 39 is capable of contacting the contact portion 55 of the conductive member 50, but the connection portion 31 of the spring member 30 may be connected to the contact portion of the conductive member 50, and the movable contact portion 39 may be capable of contacting the contact portion of the conductive member 60. Also, the connection portion 41 of the spring member 40 is connected to the contact portion 75 of the conductive member 70, and the movable contact portion 49 is capable of contacting the contact portion 66 of the conductive member 60, but the connection portion 41 of the spring member 40 may be connected to the contact portion of the conductive member 60, and the movable contact portion 39 may be capable of contacting the contact portion of the conductive member 70.
