AI Technical Summary
Existing switch designs impair the aesthetic appearance when the handle for applying a pushing force to the spring is increased to ensure proper contact between movable and fixed contacts.
The switch design incorporates an operation handle that swings to move a slide member, which in turn moves an inverted handle. This configuration allows the movable contacts to switch between contact and non-contact positions with the fixed contacts, while maintaining a compact and aesthetically pleasing form.
The solution effectively suppresses the increase in the operating handle's output, thereby improving the aesthetic appearance while ensuring reliable movement of the movable contacts, thus enhancing the overall reliability and appearance of the switch.

Description
Switches and switching devices
[0001] The present disclosure relates to a switch and a switch device, and more particularly to a switch and a switch device that switches the operating state of a load by operating an operating handle.
[0002] Patent Document 1 discloses a switch module in which a movable contact and a fixed contact are brought into contact with each other by an elastic force generated when a spring is bent by an external pressing force.
[0003] In a switch module such as that described in Patent Document 1, if the handle for applying a pressing force to the spring from the outside is enlarged, the handle protrudes more in order to ensure the amount of bending of the spring to ensure contact between the movable contact and the fixed contact, which causes a problem of spoiling the aesthetic appearance.
[0004] Japanese Patent Application Laid-Open No. 2015-153557
[0005] The present disclosure has been made in view of the above circumstances, and aims to provide a switch and a switch device that can improve aesthetic appearance.
[0006] A switch according to one aspect of the present disclosure includes an operating handle that swings in response to an operation by an operator, a sliding member that moves along a predetermined direction in response to the swinging of the operating handle, a reversing handle that swings in response to the movement of the sliding member, a fixed contact, and a movable contact that faces the fixed contact in the predetermined direction and moves between a position in contact with the fixed contact and a position away from the fixed contact in response to the swinging of the reversing handle. The operating handle includes an operating unit having an operating surface that accepts operation by the operator, and a first protrusion and a second protrusion that protrude from the operating unit in a direction intersecting the operating surface. The sliding member has a first side surface and a second side surface that face each other in the predetermined direction. The first protrusion contacts the first side surface. The second protrusion contacts the second side surface. The sliding member moves along the predetermined direction by changing the contact position of the first protrusion on the first side surface and the contact position of the second protrusion on the second side surface in response to the swinging of the operating handle.
[0007] A switch device according to one aspect of the present disclosure includes the switch and a mounting frame that holds the switch and is mountable to a construction surface.

[0009] A switch 10 and a switch device 100 according to an embodiment of the present disclosure will be described in detail with reference to the drawings. Note that the embodiment and modifications described below are merely examples of the present disclosure, and the present disclosure is not limited to the embodiment and modifications. Various modifications other than the embodiment and modifications are possible depending on the design, etc., as long as they do not deviate from the technical concept of the present disclosure. Furthermore, the following embodiments (including modifications) may be realized in appropriate combinations.
[0010] (1) Overview An overview of the switch 10 according to this embodiment will be described.
[0011] As shown in Figures 5 to 7, the switch 10 includes an operating handle 6 that swings when operated by an operator, a slide member 9 that moves in a predetermined direction (left and right direction in this embodiment) in response to the swinging of the operating handle 6, a reversing handle 4 that swings in response to the movement of the slide member 9, fixed contacts 3a and 3b, and movable contacts 5a and 5b that face the fixed contacts 3a and 3b in the predetermined direction.
[0012] The movable contact 5a moves between a position where it comes into contact with the fixed contact 3a and a position where it is separated from the fixed contact 3a in response to the swing of the reversing handle 4.
[0013] The movable contact 5b moves between a position where it comes into contact with the fixed contact 3b and a position where it is separated from the fixed contact 3b in response to the swing of the reversing handle 4.
[0014] The operating handle 6 has an operating unit 60 having an operating surface 601 that accepts operations from the operator, and a first protrusion 61 and a second protrusion 62 that protrude from the operating unit 60 in a direction intersecting with the operating surface 601.
[0015] The slide member 9 has a first side surface S7 and a second side surface S8 that face each other in a predetermined direction.
[0016] The first protrusion 61 contacts the first side surface S7.
[0017] The second protrusion 62 contacts the second side surface S8.
[0018] The slide member 9 moves along a predetermined direction by changing the contact position P1 of the first protrusion 61 on the first side surface S7 and the contact position P2 of the second protrusion 62 on the second side surface S8 in response to the swinging of the operating handle 6.
[0019] According to the above configuration, by converting the swinging of the operating handle 6 into the movement of the movable contacts 5a, 5b via the slide member 9 and the reversing handle 4, it is possible to suppress an increase in the protrusion of the operating handle 6 even when the operating handle 6 is enlarged, thereby improving the aesthetic appearance. Furthermore, according to the above configuration, it is possible to reliably move the movable contacts 5a, 5b while improving the aesthetic appearance, thereby improving reliability.
[0020] (2) Details The switch 10 and the switch device 100 according to the embodiment will be described in detail below.
[0021] In the following description, when the switch device 100 is fixed to a construction surface such as a wall, the direction perpendicular (orthogonal) to a horizontal plane may be referred to as the "up-down direction," and the downward (vertical) direction when viewed from the front of the switch device 100 may be referred to as the "downward direction." Furthermore, the direction perpendicular to the up-down direction and parallel to the surface of the wall may be referred to as the "left-right direction," and the right side when viewed from the front of the switch device 100 may be referred to as the "rightward direction" and the left side when viewed from the front of the switch device 100 may be referred to as the "leftward direction." Furthermore, the direction perpendicular to both the up-down direction and the left-right direction, i.e., the direction perpendicular to the surface of the wall, may be referred to as the "front-rear direction," and the back side of the wall (the back side of the wall) may be referred to as the "rear." In the following description, the "left-right direction," "front-rear direction," and "up-down direction" may be referred to as the "first direction," "second direction," and "third direction," respectively. However, these directions are not intended to limit the orientation of the switch device 100 when in use.
[0022] (2.1) Configuration of the Switch The configuration of the switch 10 will now be described.
[0023] As shown in FIGS. 1 and 2, a switch 10 according to this embodiment includes a switch module 1 and an operating handle 6.
[0024] 1 to 4, the switch module 1 includes a body 2, a contact device 3, a reversing handle 4, and a slide member 9. The switch module 1 further includes a coil spring .
[0025] The housing 2 is an outer shell that houses the contact device 3, the reversing handle 4, and the slide member 9. The housing 2 has a rectangular box-shaped body 21 made of synthetic resin with an open front, and a synthetic resin cover member 22 joined to the front side of the body 21.
[0026] The body 21 has a plurality of (for example, four) assembly protrusions 21 a. The assembly protrusions 21 a are provided on both outer surfaces of the body 21 that face each other in the short side direction (vertical direction) of the body 21, spaced apart in the longitudinal direction of the body 21.
[0027] The cover member 22 has a plurality of (for example, four) assembly tongues 22 a that protrude rearward from the rear end of the cover member 22 .
[0028] The assembly holes 22b provided in each of the four assembly tongues 22a and the four assembly projections 21a of the body 21 are fitted together, thereby joining the body 21 and the cover 22 together.
[0029] The body 21 houses the contact device 3. The contact device 3 includes an open / close contact for switching the operating state (on and off) of the load to be operated, and an external connection terminal for connecting to external wiring. Specifically, as shown in Figures 3 and 4, the contact device 3 includes terminal plates 31 to 33, a swinging portion 5, and locking springs 35 to 38.
[0030] Terminal boards 31 to 33 are each electrically connected to external wiring. Terminal boards 31 and 32 are housed side by side in the vertical direction at one end (e.g., the left end) of the body 21 in the longitudinal direction (left-right direction). Terminal board 33 is housed at the other end (e.g., the right end) of the body 21 in the longitudinal direction.
[0031] Terminal board 31 includes a connecting piece 311, a pressure contact piece 312, and a contact piece 313. Pressure contact piece 312 and a contact piece 313 are connected to connecting piece 311 so as to face each other. More specifically, pressure contact piece 312 protrudes rearward from the left end of connecting piece 311, and a contact piece 313 protrudes rearward from the right end of connecting piece 311.
[0032] The terminal board 31 further includes a contact piece 314 on which a fixed contact 3a (see FIGS. 5 to 7) is provided. The contact piece 314 protrudes downward from the connecting piece 311. The fixed contact 3a is provided at the lower end of the contact piece 314.
[0033] The terminal board 32 includes a connecting piece 321, a pressure contact piece 322, and a contact piece 323. The pressure contact piece 322 and the contact piece 323 are connected to the connecting piece 321 so as to face each other. More specifically, the pressure contact piece 322 protrudes rearward from the left end of the connecting piece 321, and the contact piece 323 protrudes rearward from the right end of the connecting piece 321.
[0034] The terminal board 32 further includes a contact piece 324 on which the fixed contact 3b (see FIGS. 5 to 7) is provided, and a connecting piece 325. The connecting piece 325 protrudes to the right from the linking piece 321. The contact piece 324 protrudes upward from the right end of the connecting piece 325. The fixed contact 3b is provided at the front end of the contact piece 324.
[0035] Terminal board 31 and terminal board 32 are housed in body 21 such that contact piece 314 and contact piece 324 face each other in the left-right direction.
[0036] The terminal board 33 includes connecting pieces 331 and 332, a pair of pressure contact pieces 333 and 334, and a pair of contact pieces 335 and 336. The pressure contact pieces 333 and 334 are arranged side by side in the vertical direction. The contact pieces 335 and 336 are also arranged side by side in the vertical direction.
[0037] The pressure contact piece 333 and the abutment piece 335 are connected to the upper end of the connecting piece 331 so as to face each other. The pressure contact piece 334 and the abutment piece 336 are connected to the lower end of the connecting piece 331 so as to face each other.
[0038] The terminal board 33 further includes a support piece 337 that supports the swinging portion 5 (described later) (see FIGS. 4 to 7). The support piece 337 protrudes leftward from the center in the vertical direction of the connecting piece 332 that connects the rear ends of the abutting pieces 335 and 336.
[0039] Each of the locking springs 35 to 38 is formed by bending both ends of a strip of elastic conductive metal.
[0040] The locking spring 35 abuts against the abutment piece 313 of the terminal plate 31 and faces the insulation displacement piece 312. When an electric wire is inserted into the body 21 through the first electric wire insertion hole H1 (see FIG. 2 ) provided on the rear surface of the body 21, the electric wire is clamped between the locking spring 35 and the insulation displacement piece 312. As a result, the tip of the locking spring 35 bites into the core wire of the electric wire, preventing it from coming out, and the locking spring 35 electrically connects the electric wire to the terminal plate 31. In other words, the contact device 3 includes a quick-connect terminal C1 including the locking spring 35 and the insulation displacement piece 312. The insulation displacement piece 312 is electrically connected to the fixed contact 3a via the linking piece 311, the connecting piece 315, and the contact piece 314. Therefore, the quick-connect terminal C1 is electrically connected to the fixed contact 3a.
[0041] The locking spring 36 abuts against the abutment piece 323 of the terminal plate 32 and faces the insulation displacement piece 322. When an electric wire is inserted into the body 21 through the second electric wire insertion hole H2 (see FIG. 2), the electric wire is clamped between the locking spring 36 and the insulation displacement piece 322. As a result, the tip of the locking spring 36 bites into the core wire of the electric wire, preventing it from coming out, and the locking spring 36 electrically connects the electric wire to the terminal plate 32. In other words, the contact device 3 includes a quick-connect terminal C2 including the locking spring 36 and the insulation displacement piece 322. Here, the insulation displacement piece 322 is electrically connected to the fixed contact 3b via the linking piece 321, the connecting piece 325, and the contact piece 324. Therefore, the quick-connect terminal C2 is electrically connected to the fixed contact 3b.
[0042] The locking spring 37 abuts against the abutment piece 335 of the terminal plate 33 and faces the insulation displacement piece 333. When an electric wire is inserted into the body 21 through a third electric wire insertion hole H3 (see FIG. 2 ) provided on the rear surface of the body 21, the electric wire is clamped between the locking spring 37 and the insulation displacement piece 333. As a result, the tip of the locking spring 37 bites into the core wire of the electric wire to prevent it from coming out, and the locking spring 37 electrically connects the electric wire to the terminal plate 33. In other words, the contact device 3 includes a quick-connect terminal C3 that includes the locking spring 37 and the insulation displacement piece 333.
[0043] The locking spring 38 abuts against the abutment piece 336 of the terminal plate 33 and faces the insulation displacement piece 334. When an electric wire is inserted into the body 21 through a fourth electric wire insertion hole H4 (see FIG. 2 ) provided on the rear surface of the body 21, the electric wire is clamped between the locking spring 38 and the insulation displacement piece 334. As a result, the tip of the locking spring 38 bites into the core wire of the electric wire to prevent it from coming out, and the locking spring 38 electrically connects the electric wire to the terminal plate 33. In other words, the contact device 3 includes a quick-connect terminal C4 that includes the locking spring 38 and the insulation displacement piece 334.
[0044] The oscillating portion 5 is, for example, a rectangular flat plate-like member. As shown in Figures 5 to 7, a movable contact 5a is provided on a first surface S1 of the oscillating portion 5, and a movable contact 5b is provided on a second surface S2.
[0045] The oscillating portion 5 is housed in the center of the body 21. More specifically, the oscillating portion 5 is housed in the center of the body 21 so that the movable contact 5a faces the fixed contact 3a and the movable contact 5b faces the fixed contact 3b.
[0046] As shown in FIGS. 5 to 7, the first end Ea1 of the oscillating portion 5 in the longitudinal direction is inserted into the coil spring 7 from one end (second end Eb2) of the coil spring 7.
[0047] A second longitudinal end Ea2 of the oscillating portion 5 is in contact with the support piece 337 of the terminal board 33. In other words, the oscillating portion 5 is housed in the body 21 in a state in which it is electrically connected to the terminal board 33.
[0048] The swinging portion 5 swings around a contact position P0 between the support piece 337 and the second end Ea2 of the swinging portion 5 as a fulcrum.
[0049] Here, the movable contact 5a and the fixed contact 3a form one switching contact (first switching contact) Q1, and the movable contact 5b and the fixed contact 3b form one switching contact (second switching contact) Q2.
[0050] The swinging of the swinging part 5 alternately switches the first switching contact Q1 and the second switching contact Q2 between a closed state and an open state. That is, the swinging part 5 swings around the contact position P0 as a fulcrum, so that the movable contact 5a can move between a position in contact with the fixed contact 3a and a position away from the fixed contact 3a. The swinging part 5 swings around the contact position P0 as a fulcrum, so that the movable contact 5b can move between a position in contact with the fixed contact 3b and a position away from the fixed contact 3b.
[0051] Such a switch 10, in which two open / close contacts are alternately switched by the swinging part 5, is called a three-way switch. This three-way switch can be used, for example, as a switch installed on the upper and lower floors of a staircase to turn on and off a common lighting fixture that illuminates the staircase.
[0052] As shown in FIGS. 3 and 4 , the cover member 22 has a bottom portion 220 , a pair of first wall portions 221 , and a pair of second wall portions 222 .
[0053] The bottom portion 220 is a plate-like portion whose thickness direction is along the front-rear direction. The bottom portion 220 has an opening 22c formed in a rectangular frame shape. The opening 22c is an opening through which a part of the reversing handle 4 (a tubular portion 42 described later) is inserted.
[0054] As shown in FIGS. 5 to 7, the bottom portion 220 is disposed between the contact device 3 having the fixed contacts 3a, 3b and the operating handle 6 in the front-rear direction.
[0055] The bottom portion 220 has a first surface S3 on the operating handle 6 side and a second surface S4 on the contact device 3 side.
[0056] The pair of first wall portions 221 protrude in the front-rear direction from the first surface S3. More specifically, the pair of first wall portions 221 protrude forward from both ends of the first surface S3 in the up-down direction.
[0057] The pair of second wall portions 222 protrude in the front-rear direction from the first surface S3. More specifically, the pair of second wall portions 222 protrude forward from both ends of the first surface S3 in the left-right direction.
[0058] In this embodiment, the bottom 220, the pair of first wall portions 221, and the pair of second wall portions 222 are, for example, integrally formed. Note that the bottom 220, the pair of first wall portions 221, and the pair of second wall portions 222 may also be formed separately.
[0059] The bottom 220, the pair of first wall portions 221, and the pair of second wall portions 222 form a space Sp1. The cover member 22 accommodates a slide member 9 (described later) in the space Sp1. That is, the pair of first wall portions 221 face each other in the up-down direction, separated by the space Sp1 in which the slide member 9 is accommodated. Furthermore, the pair of second wall portions 222 face each other in the left-right direction, separated by the space Sp1.
[0060] The cover member 22 further has a plurality of (for example, four) contact portions 223 that come into contact with the slide member 9 housed in the space Sp1 that separates the pair of first wall portions 221. The four contact portions 223 are provided on the first surface S3 of the bottom portion 220. In other words, the slide member 9 comes into contact with the bottom portion 220 via the four contact portions 223. This makes it easier for the slide member 9 to move in the left-right direction compared to when the slide member 9 comes into direct contact with the bottom portion 220.
[0061] In this embodiment, each of the four contact portions 223 is a rib R0 that protrudes forward in the front-rear direction. The rib R0 extends in the left-right direction.
[0062] The cover member 22 also includes a retaining portion 224 provided on at least one of the pair of first wall portions 221. In this embodiment, a retaining portion 224 is provided on each of the pair of first wall portions 221. More specifically, two retaining portions 224 are provided on each of the pair of first wall portions 221. That is, the cover member 22 has four retaining portions 224. As described above, the pair of first wall portions 221 protrude forward in the second direction from the first surface S3 of the bottom portion 220 on the operating handle 6 side. Therefore, the pair of retaining portions 224 are located on the opposite side from the fixed contacts 3a and 3b, which generate heat when current is applied. This prevents damage to the pair of retaining portions 224 due to heat, arcs, and the like generated when the fixed contact 3a and the movable contact 5a are turned on / off, and when the fixed contact 3b and the movable contact 5b are turned on / off. This also increases the flexibility in selecting materials for the pair of retaining portions 224 and the cover member 22.
[0063] The two holding portions 224 provided on each of the pair of first wall portions 221 are provided at a distance from each other in the left-right direction on the inner surface of the first wall portion 221 (the surface facing the other first wall portion 221). The two holding portions 224 are also provided at positions spaced apart from each other with respect to the first surface S3 of the bottom portion 220.
[0064] In this embodiment, the holding portions 224 are ribs (first ribs) R1 that protrude in the vertical direction from the inner surface of the first wall portion 221. That is, the two holding portions 224 (first ribs R1) provided on the upper first wall portion 221 protrude downward, and the two holding portions 224 (first ribs R1) provided on the lower first wall portion 221 protrude upward.
[0065] The cover member 22 further includes a pair of support portions 225 that swingably support the operating handle 6 and the reversing handle 4, which will be described later.
[0066] The pair of support portions 225 protrude forward from the front ends of the pair of first wall portions 221. The width of the support portions 225 in the left-right direction is formed to narrow toward the front. The front end of the support portion 225 is provided with a support hole 226, which is a through-hole that passes through the support portion 225 in the up-down direction.
[0067] The slide member 9 is, for example, a rectangular flat plate-like member.
[0068] The slide member 9 is housed in a space Sp1 formed by the bottom 220 of the cover member 22, the pair of first wall portions 221, and the pair of second wall portions 222 so as to face the operating handle 6 in the front-rear direction. More specifically, the slide member 9 is disposed behind the operating handle 6. Furthermore, the slide member 9 is disposed in the space Sp1 so that its longitudinal direction is aligned with the left-right direction and its lateral direction is aligned with the up-down direction.
[0069] As shown in FIGS. 5 to 8, the slide member 9 has a front surface S5 and a rear surface S6 that face each other in the front-rear direction.
[0070] The front surface S5 is a surface that faces the operating handle 6 when the slide member 9 is housed in the space Sp1.
[0071] When the slide member 9 is housed in the space Sp1, the rear surface S6 faces the first surface S3 of the bottom 220. When the slide member 9 is housed in the space Sp1, the rear surface S6 comes into contact with the four contact portions 223 provided on the first surface S3.
[0072] 5 to 7, the slide member 9 has a first side surface S7 and a second side surface S8 that face each other in the left-right direction. That is, the first side surface S7 is the left end surface of the slide member 9, and the second side surface S8 is the right end surface of the slide member 9.
[0073] Here, the width of the slide member 9 in the left-right direction becomes narrower as it approaches the operating handle 6 in the front-rear direction. In other words, the first side surface S7 and the second side surface S8 are inclined with respect to the front-rear direction so that they approach each other as they go forward.
[0074] 8, the slide member 9 has an upper surface S9 and a lower surface S10 that face each other in the vertical direction. That is, the upper surface S9 is the upper end surface of the slide member 9, and the lower surface S10 is the lower end surface of the slide member 9. Furthermore, the slide member 9 has a held portion 91 provided on at least one of the upper surface S9 and the lower surface S10. In this embodiment, the held portion 91 is provided on both the upper surface S9 and the lower surface S10.
[0075] In this embodiment, the held portions 91 are ribs (second ribs) R2 that protrude in the up-down direction from each of the upper surface S9 and the lower surface S10. The second ribs R2 extend in the left-right direction.
[0076] Here, the pair of holding portions 224 (first ribs R1) described above respectively hold the pair of held portions 91 (second ribs R2) while allowing the slide member 9 to move in the left-right direction. This stabilizes the movement of the slide member 9 in the left-right direction. It also prevents the slide member 9 from falling out of the space Sp1. The holding of the second rib R2 by the first rib R1 will be specifically described below.
[0077] 8 , when the slide member 9 is housed in the space Sp1, the second rib R2 is sandwiched between the first rib R1 of the cover member 22 and the bottom 220 of the cover member 22. More specifically, the second rib R2 provided on the upper surface S9 is sandwiched between the two first ribs R1 provided on the upper first wall portion 221 and the bottom 220. Furthermore, the second rib R2 provided on the lower surface S10 is sandwiched between the two first ribs R1 provided on the lower first wall portion 221 and the bottom 220.
[0078] 3 and 4, the slide member 9 has an opening 92 formed in a rectangular frame shape. The opening 92 is an opening through which a part of the reversing handle 4 (a cylindrical portion 42 described later) is inserted.
[0079] The reversing handle 4 is a member that swings in response to the left-right movement of the slide member 9 .
[0080] As shown in FIGS. 5 to 7, the reversing handle 4 has a base portion 41 and a cylindrical portion 42 .
[0081] The base 41 is a plate-shaped portion disposed between the operating handle 6 and the slide member 9 .
[0082] The cylindrical portion 42 is a portion that protrudes from the base portion 41 toward the slide member 9 .
[0083] In this embodiment, the base portion 41 and the cylindrical portion 42 are formed integrally, for example. However, the base portion 41 and the cylindrical portion 42 may be formed separately.
[0084] The base 41 is formed, for example, in a rectangular shape. The base 41 has a pair of through holes 410 arranged side by side in the longitudinal direction of the base 41. A pair of third protrusions 63 of the operating handle 6 (described later) is inserted into the pair of through holes 410, respectively.
[0085] 3 and 4, the base 41 has a pair of first fulcrum portions 411 that serve as fulcrums for the swing of the reversing handle 4. The pair of first fulcrum portions 411 are protrusions that protrude from the center positions in the longitudinal direction of both surfaces of the base 41 that face each other in the short direction.
[0086] 9 , the pair of first fulcrum portions 411 are inserted from the inside into the support holes 226 of the pair of support portions 225 of the cover member 22. Specifically, the upper first fulcrum portion 411 is inserted from below into the upper support hole 226, and the lower first fulcrum portion 411 is inserted from above into the lower support hole 226. This allows the reversing handle 4 to swing within a predetermined angle range, with the pair of first fulcrum portions 411 inserted into the pair of support holes 226 as fulcrums. In other words, the reversing handle 4 is swingably supported by the pair of support portions 225 of the cover member 22.
[0087] The cylindrical portion 42 is inserted into an opening 92 of the slide member 9 disposed behind the base portion 41 .
[0088] One end (first end) Eb1 of the coil spring 7 is inserted into the cylindrical portion 42. The first end Eb1 of the coil spring 7 is fixed to an end portion inside the cylindrical portion 42.
[0089] 5 to 7, the second end Eb2 of the coil spring 7 is exposed from the end of the cylindrical portion 42. Here, the first end Ea1 in the longitudinal direction of the oscillating portion 5 is inserted into the coil spring 7 from the second end Ea2.
[0090] The operating handle 6 is a member that swings when operated by an operator.
[0091] As shown in FIGS. 5 to 7, the operating handle 6 has an operating portion 60, a first protruding portion 61, a second protruding portion 62, and a pair of third protruding portions 63.
[0092] The operation unit 60 is formed in the shape of a rectangular plate that is sufficiently larger than the size of the switch module 1 when viewed from the front and rear.
[0093] The operation unit 60 has an operation surface 601 that receives operations by an operator. The operation unit 60 is disposed so as to face the slide member 9 in the front-rear direction.
[0094] The first protrusion 61 and the second protrusion 62 protrude from the operating unit 60 in a direction intersecting with the operating surface 601. More specifically, the first protrusion 61 and the second protrusion 62 protrude from the operating unit 60 in a direction toward the slide member 9. The first protrusion 61 and the second protrusion 62 have the same length in the protruding direction. The first protrusion 61 and the second protrusion 62 are formed, for example, in the shape of a rectangular plate.
[0095] The first protrusion 61 and the second protrusion 62 are provided to face each other in the left-right direction.
[0096] 5 to 7, the tip of the first protrusion 61 contacts the first side surface S7, which is the left end surface of the slide member 9. In addition, the tip of the second protrusion 62 contacts the second side surface S8, which is the right end surface of the slide member 9.
[0097] The pair of third protrusions 63 protrude from the operating unit 60 in a direction intersecting the operating surface 601. More specifically, the pair of third protrusions 63 protrude from the operating unit 60 in a direction toward the slide member 9. The pair of third protrusions 63 are provided between the first protrusion 61 and the second protrusion 62 so as to face each other in the left-right direction.
[0098] The pair of third protrusions 63 are inserted into a pair of through holes 410 in the base 41 of the reversing handle 4, respectively. This improves workability when assembling the switch module 1. That is, a worker assembling the switch module 1 can easily assemble the pair of third protrusions 63 to the reversing handle 4 using the pair of through holes 410 as guides.
[0099] The length of the pair of third protrusions 63 in the protruding direction is shorter than the length of the first protrusion 61 and the second protrusion 62 in the protruding direction, and the tips of the pair of third protrusions 63 do not come into contact with the slide member 9 arranged behind the base 41.
[0100] As shown in FIGS. 1, 2 and 9 , the operating handle 6 further includes a pair of wall portions 64 that protrude from the operating portion 60 in a direction intersecting with the operating surface 601 .
[0101] The pair of wall portions 64 face each other in the up-down direction via the first protruding portion 61 , the second protruding portion 62 , and the pair of third protruding portions 63 .
[0102] The pair of wall portions 64 each have a second fulcrum portion 641 that serves as a fulcrum for the swing of the operating handle 6. In other words, the operating handle 6 has a pair of second fulcrum portions 641. The pair of second fulcrum portions 641 are protrusions that protrude in directions approaching each other from the center positions of the pair of wall portions 64 in the longitudinal direction.
[0103] 9 , the pair of second fulcrum portions 641 are inserted from the outside into the support holes 226 of the pair of support portions 225 of the cover member 22. Specifically, the upper second fulcrum portion 641 is inserted from above into the upper support hole 226, and the lower second fulcrum portion 641 is inserted from below into the lower support hole 226. This allows the operating handle 6 to swing within a predetermined angle range, with the pair of second fulcrum portions 641 inserted into the pair of support holes 226 as fulcrums. In other words, the operating handle 6 is swingably supported by the pair of support portions 225 of the cover member 22.
[0104] As described above, the reversing handle 4 is supported by the pair of support parts 225 so that the pair of first fulcrums 411 are inserted from the inside into the support holes 226 of the pair of support parts 225, as shown in Fig. 9. In other words, each of the pair of support parts 225 supports the first fulcrum part 411 and the second fulcrum part 641 so that the first fulcrum part 411 and the second fulcrum part 641 overlap when viewed from the top and bottom. This allows the switch 10 to be more compact than when the first fulcrum part 411 and the second fulcrum part 641 are supported at different locations.
[0105] (2.2) Configuration of Switch Device Next, a switch device 100 using the switch 10 will be described with reference to FIGS. 1 and 2. FIG.
[0106] The switch device 100 according to this embodiment includes a switch 10 and a mounting frame 8 that holds the switch 10 and can be mounted on an installation surface.
[0107] The mounting frame 8 is formed into a rectangular frame shape using synthetic resin or a metal plate. The mounting frame 8 has a rectangular window hole 81 formed therein, into which the switch module 1 is attached. The mounting frame 8 includes a pair of first beam portions 82 and a pair of second beam portions 83. The pair of first beam portions 82 face each other in the vertical direction, sandwiching the window hole 81 therebetween. The pair of second beam portions 83 face each other in the horizontal direction, sandwiching the window hole 81 therebetween.
[0108] Each of the pair of second beam portions 83 is formed with an insertion hole 84 into which a screw (not shown) is inserted to fix the second beam portion 83 to the construction surface.
[0109] Furthermore, a plurality of (for example, six) fitting grooves 85 (851 to 856) are formed in the up-down direction in each of the pair of second beam portions 83. The fitting grooves 851 to 856 are formed so that the spacing between fitting groove 851 and fitting groove 852, the spacing between fitting groove 853 and fitting groove 854, and the spacing between fitting groove 855 and fitting groove 856 are aligned at the same intervals as the two mounting claws 22d provided on each of the left and right side surfaces of the switch module 1 (cover member 22).
[0110] The two mounting claws 22d provided on the left side surface of the cover member 22 engage with any of the left fitting grooves 851 and 852, the left fitting grooves 853 and 854, or the left fitting grooves 855 and 856. The two mounting claws 22d provided on the right side surface of the cover member 22 engage with any of the right fitting grooves 851 and 852, the right fitting grooves 853 and 854, or the right fitting grooves 855 and 856. The switch module 1 is held in the mounting frame 8 by the two mounting claws 22d provided on the left side surface of the cover member 22 and the two mounting claws 22d provided on the right side surface of the cover member 22 engaging with the two fitting grooves 85 on the left side and the two fitting grooves 85 on the right side, which are at the same position in the up-down direction.
[0111] An operating handle 6 is attached from the front to the switch module 1 held by the mounting frame 8 .
[0112] In this way, the mounting frame 8 can be mounted on a construction surface while holding the switch 10 in a state in which the operating handle 6 can be operated from the front.
[0113] (2.3) Description of Operation of Switch Device The following describes the operation of the switch device 100. In the following description, it is assumed that, in the initial state, as shown in FIG. 5, the second switching contact Q2 (movable contact 5b and fixed contact 3b) is in a closed state and the first switching contact Q1 (movable contact 5a and fixed contact 3a) is in an open state.
[0114] In the initial state where the second switching contact Q2 is in the closed state, the swinging part 5 is tilted to the right, with the fulcrum being the contact position P0 between the support piece 337 and the second end Ea2 of the swinging part 5. As a result, the coil spring 7 into which the first end Ea1 of the swinging part 5 is inserted and the reversing handle 4 into which the coil spring 7 is inserted are tilted to the left.
[0115] In addition, in the initial state, the slide member 9 through which the tubular portion 42 of the reversing handle 4 is inserted is positioned to the right within the space Sp1. As a result, the contact position P1 between the tip of the first protrusion 61 and the first side surface S7 of the slide member 9 is located behind the contact position P2 between the tip of the second protrusion 62 and the second side surface S8 of the slide member 9. In other words, in the initial state, the operating handle 6 is tilted to the left.
[0116] As shown in FIG. 6, when the operator presses the right end of the operating handle 6 rearward, the operating handle 6 swings clockwise around the pair of second fulcrum portions 641 as fulcrums.
[0117] As described above, the tip of the first protrusion 61 of the operating handle 6 is in contact with the first side surface S7, which is the left end surface of the slide member 9. Also, the tip of the second protrusion 62 of the operating handle 6 is in contact with the second side surface S8, which is the right end surface of the slide member 9.
[0118] At this time, since the first side surface S7 and the second side surface S8 are inclined relative to the front-to-rear direction so as to approach each other as they move forward, when the operating handle 6 is swung clockwise, as shown in FIG. 6 , a contact position P1 between the tip of the first protrusion 61 and the first side surface S7 of the slide member 9 moves forward and to the right along the first side surface S7. Also, a contact position P2 between the tip of the second protrusion 62 and the second side surface S8 of the slide member 9 moves rearward and to the right along the second side surface S8. As a result, a leftward force is applied from the second protrusion 62 to the slide member 9, and the slide member 9 moves leftward within the space Sp1. In other words, the pushing force applied to the operating handle 6 toward the rear is converted into a force that moves the slide member 9 leftward.
[0119] When the slide member 9 moves to the left, a leftward force is applied from the slide member 9 to the cylindrical portion 42 of the reversing handle 4. As a result, the reversing handle 4 swings clockwise around the pair of first fulcrum portions 411 as fulcrums.
[0120] As the reversing handle 4 pivots clockwise, the coil spring 7 inserted inside the cylindrical portion 42 of the reversing handle 4 also deforms so that the second end Eb2 moves to the left. Here, because the first end Ea1 of the pivoting part 5 is inserted into the second end Eb2 of the coil spring 7, the pivoting part 5 pivots counterclockwise around the contact position P0 as a fulcrum. As a result, the movable contact 5b moves to a position away from the fixed contact 3b. In other words, the second open / close contact Q2 is opened.
[0121] As shown in FIG. 7, when the operator further pushes the right end portion of the operating handle 6 rearward, the operating handle 6 further swings clockwise around the pair of second fulcrum portions 641 as fulcrums.
[0122] When the operating handle 6 is further swung clockwise, the first sliding member 9 moves further to the left within the space Sp1.
[0123] When the slide member 9 moves to the left, the reversing handle 4 further swings clockwise around the pair of first fulcrum portions 411 as fulcrums.
[0124] As the reversing handle 4 is further swung clockwise, the swinging portion 5 further swings counterclockwise around the contact position P0 as a fulcrum, causing the movable contact 5a to move to a position where it contacts the fixed contact 3a. In other words, the first switching contact Q1 is brought into a closed state.
[0125] (3) Modifications The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Modifications of the above embodiment are listed below. The modifications described below can be applied in appropriate combinations.
[0126] 10, the held portions 91 may be groove portions G1 provided on the upper surface S9 and the lower surface S10 of the slide member 9. In this case, the pair of holding portions 224 (first ribs R1) are sandwiched between the pair of groove portions G1 while the slide member 9 is movable in the left-right direction.
[0127] As shown in FIG. 10 , the slide member 9 may further have a contact portion 93 provided on the rear surface S6. The slide member 9 has a plurality of contact portions 93. Each of the plurality of contact portions 93 is, for example, a rib protruding along the front-rear direction. The contact portion 93, which is a rib, extends, for example, along the left-right direction. Here, as shown in FIG. 10 , when the slide member 9 has a plurality of contact portions 93, a plurality of contact portions 223 may not be provided on the first surface S3 of the bottom portion 220 of the cover member 22. In this case, the plurality of contact portions 93 of the slide member 9 come into contact with the first surface S3 of the bottom portion 220 when the slide member 9 is housed in the space Sp1.
[0128] The contact portion 223 provided on the first surface S3 of the bottom portion 220 of the cover member 22 may be a protrusion D1 that protrudes forward in the front-to-rear direction as shown in Fig. 11. The outer surface of the protrusion D1 forms, for example, a part of a spherical surface.
[0129] As shown in FIG. 12 , at least one groove 94 may be provided on at least one of the first side surface S7 and the second side surface S8 of the slide member 9. The slide member 9 shown in FIG. 12 has four grooves 94 provided on each of the first side surface S7 and the second side surface S8. The four grooves 94 provided on the first side surface S7 are aligned, for example, parallel to each other in the vertical direction. This reduces the contact area between the tip of the first protrusion 61 and the first side surface S7 and the contact area between the tip of the second protrusion 62 and the second side surface S8, making it easier for the tip of the first protrusion 61 to move along the first side surface S7 and the tip of the second protrusion 62 to move along the second side surface S8.
[0130] As shown in FIG. 13 , the switch module 1 may include pillar terminals PC1 and PC2 instead of the quick-connect terminals C1 and C2. The pillar terminal PC1 includes a terminal plate L1 electrically connected to the fixed contact 3a and a screw Sc1 provided on the left side surface of the body 21. The pillar terminal PC2 includes a terminal plate L2 electrically connected to the fixed contact 3b and a screw Sc2 provided on the left side surface of the body 21. Conventional well-known structures can be used for the connection structure between the fixed contact 3a and the terminal plate L1 and the connection structure between the fixed contact 3b and the terminal plate L2. With an electric wire inserted into the body 21 through the first electric wire insertion hole Ha1, the electric wire and the terminal plate L1 are electrically connected by tightening the screw Sc1. With an electric wire inserted into the body 21 through the second electric wire insertion hole Ha2, the electric wire and the terminal plate L2 are electrically connected by tightening the screw Sc2.
[0131] The switch 10 is not limited to a three-way switch. For example, the switch 10 may be a single-pole switch that includes only one of the first and second switching contacts Q1 and Q2.
[0132] (4) Summary As described above, the switch (10) according to the first aspect includes an operating handle (6) that swings when operated by an operator, a slide member (9) that moves in a predetermined direction in response to the swinging of the operating handle (6), a reversing handle (4) that swings in response to the movement of the slide member (9), fixed contacts (3a, 3b), and movable contacts (5a, 5b) that face the fixed contacts (3a, 3b) in a predetermined direction. The movable contacts (5a, 5b) move between a position in contact with the fixed contacts (3a, 3b) and a position away from the fixed contacts (3a, 3b) in response to the swinging of the reversing handle (4). The operating handle (6) includes an operating unit (60) having an operating surface (601) that accepts operation by the operator, and a first protrusion (61) and a second protrusion (62) that protrude from the operating unit (60) in a direction intersecting the operating surface (601). The slide member (9) has a first side surface (S7) and a second side surface (S8) that face each other in a predetermined direction. The first protrusion (61) contacts the first side surface (S7). The second protrusion (62) contacts the second side surface (S8). The slide member (9) moves along the predetermined direction as the contact position (P1) of the first protrusion (61) on the first side surface (S7) and the contact position (P2) of the second protrusion (62) on the second side surface (S8) change in response to the swing of the operating handle (6).
[0133] According to this aspect, by converting the swinging of the operating handle (6) into the movement of the movable contacts (5a, 5b) via the slide member (9) and the reversing handle (4), even if the operating handle (6) is enlarged, an increase in the protrusion of the operating handle (6) can be suppressed, thereby improving the aesthetic appearance. Furthermore, according to this aspect, the movable contacts (5a, 5b) can be reliably moved while improving the aesthetic appearance, thereby improving reliability. Furthermore, by having the movable contacts (5a, 5b) and the fixed contacts (3a, 3b) face each other in the same predetermined direction as the moving direction of the slide member (9), the dimension of the switch (10) in the predetermined direction can be shortened compared to when the movable contacts (5a, 5b) and the fixed contacts (3a, 3b) face each other in a direction intersecting the predetermined direction.
[0134] In the switch (10) according to the second aspect, in the first aspect, the slide member (9) is disposed so as to face the operating handle (6) in a second direction intersecting with the first direction, which is a predetermined direction. The width of the slide member (9) in the first direction becomes narrower as it approaches the operating handle (6) along the second direction.
[0135] According to this aspect, the first side (S7) and the second side (S8) of the slide member (9) are inclined in the second direction so as to approach each other as they move in the direction toward the operating handle (6) along the second direction, thereby changing the direction of the force transmitted from the first protrusion (61) and the second protrusion (62) to the slide member (9).
[0136] In a switch (10) according to a third aspect, in the first or second aspect, the operating handle (6) further includes a third protrusion (63) protruding from the operating portion (60) along a direction intersecting the operating surface (601). The reversing handle (4) includes a through hole (410). The third protrusion (63) is inserted into the through hole (410).
[0137] According to this aspect, the workability during assembly of the switch module (1) provided in the switch (10) is improved.
[0138] A switch (10) according to a fourth aspect is any of the first to third aspects, further comprising a coil spring (7) and a plate-shaped swinging portion (5) on which movable contacts (5a, 5b) are provided. The reversing handle (4) has a plate-shaped base (41) disposed between the operating handle (6) and the sliding member (9) and a cylindrical portion (42) protruding from the base (41) toward the sliding member (9). A first end (Eb1) of the coil spring (7) is inserted into the cylindrical portion (42). At least a portion of the swinging portion (5) is inserted into the coil spring (7) from its second end (Eb2). The coil spring (7) deforms in response to the swinging of the reversing handle (4), causing the movable contacts (5a, 5b) to move between a position in contact with the fixed contacts (3a, 3b) and a position away from the fixed contacts (3a, 3b).
[0139] According to this aspect, the movable contacts (5a, 5b) can be moved more reliably.
[0140] A switch (10) according to a fifth aspect is any of the first to fourth aspects, further including a cover member (22) that houses the slide member (9). The slide member (9) is arranged to face the operating handle (6) in a second direction that intersects with a first direction, which is a predetermined direction. The cover member (22) has a pair of wall portions (221) that face each other across a space (Sp1) in which the slide member (9) is housed in a third direction that intersects with both the first and second directions, and a holding portion (224) provided on at least one of the pair of wall portions (221). The slide member (9) has an upper surface (S9) and a lower surface (S10) that face each other in the third direction, and a held portion (91) that is provided on at least one of the upper surface (S9) and the lower surface (S10). The holding portion (224) holds the held portion (91) while the slide member (9) is movable along the first direction.
[0141] According to this aspect, the movement of the slide member (9) in the left-right direction can be stabilized, and the slide member (9) can be prevented from falling out of the space (Sp1).
[0142] In the switch (10) according to the sixth aspect, in the fifth aspect, the cover member (22) further has a plate-shaped bottom portion (220) disposed between the fixed contacts (3 a, 3 b) and the operating handle (6). The pair of walls (221) protrude in the second direction from one surface (S3) of the bottom portion (220) facing the operating handle (6).
[0143] According to this aspect, the holding portion (224) provided on at least one of the pair of wall portions (221) is located on the opposite side of the fixed contacts (3a, 3b) that generate heat when current is applied, thereby suppressing the temperature rise of the holding portion (224).
[0144] In the switch (10) according to the seventh aspect, in the sixth aspect, the retaining portion (224) is a first rib (R1) protruding from at least one of the pair of wall portions (221) along the third direction. The retained portion (91) is a second rib (R2) protruding from at least one of the upper surface (S9) and the lower surface (S10) along the third direction. The second rib (R2) is sandwiched between the first rib (R1) and the bottom portion (220).
[0145] According to this aspect, the holding portion (224) and the held portion (91) can be easily formed.
[0146] In the switch (10) according to the eighth aspect, in the fifth aspect, the retaining portion (224) is a rib (R1) protruding from at least one of the pair of wall portions (221) along the third direction. The retained portion (91) is a groove portion (G1) provided on at least one of the upper surface (S9) and the lower surface (S10). The rib (R1) is clamped in the groove portion (G1).
[0147] According to this aspect, the movement of the slide member (9) in the left-right direction can be more stabilized, and the slide member (9) can be more reliably prevented from falling out of the space (Sp1).
[0148] In a switch (10) according to a ninth aspect, in any one of the fifth to eighth aspects, the reversing handle (4) further has a first fulcrum portion (411) that serves as a fulcrum for swinging. The operating handle (6) further has a second fulcrum portion (641) that serves as a fulcrum for swinging. The cover member (22) further has a support portion (225) that supports the first fulcrum portion (411) and the second fulcrum portion (641) so that the first fulcrum portion (411) and the second fulcrum portion (641) overlap when viewed from a third direction.
[0149] According to this aspect, the switch (10) can be made smaller than when the first fulcrum portion (411) and the second fulcrum portion (641) are supported at different locations.
[0150] In the switch (10) according to the tenth aspect, in the sixth or seventh aspect, the cover member (22) further includes a contact portion (223) that contacts the slide member (9) housed in the space (Sp1) separating the pair of walls (221). The contact portion (223) is provided on one surface (S3) of the bottom portion (220).
[0151] According to this aspect, the slide member (9) contacts the bottom (220) via the contact portion (223), making it easier for the slide member (9) to move in a predetermined direction compared to when the slide member (9) directly contacts the bottom (220).
[0152] In the switch (10) according to an eleventh aspect, in the sixth or seventh aspect, the slide member (9) further has a rear surface (S6) facing the one surface (S3) of the bottom (220) of the cover member (22), and a contact portion (93) provided on the rear surface (S6). The contact portion (93) comes into contact with the one surface (S3) when the slide member (9) is housed in the space (Sp1).
[0153] According to this aspect, the slide member (9) contacts the bottom (220) via the contact portion (93), making it easier for the slide member (9) to move in the first direction compared to when the slide member (9) directly contacts the bottom (220).
[0154] In the switch (10) according to a twelfth aspect, in the tenth or eleventh aspect, the contact portion (223) is a rib (R0) that protrudes along the second direction. The rib (R0) extends along the first direction.
[0155] According to this aspect, the slide member (9) can move more easily in the first direction.
[0156] In the switch (10) according to a thirteenth aspect, in the tenth or eleventh aspect, the contact portion (223) is a protrusion (D1) protruding in the second direction. The outer surface of the protrusion (D1) forms a part of a spherical surface.
[0157] According to this aspect, the contact portion (223) can be easily formed.
[0158] In the switch (10) according to the fourteenth aspect, in any of the first to thirteenth aspects, at least one groove portion (94) is provided on at least one of the first side surface (S7) and the second side surface (S8) of the slide member (9).
[0159] According to this aspect, at least one of the contact area between the tip of the first protrusion (61) and the first side surface (S7) and the contact area between the tip of the second protrusion (62) and the second side surface (S8) can be reduced, thereby facilitating at least one of the movement of the tip of the first protrusion (61) along the first side surface (S7) and the movement of the tip of the second protrusion (62) along the second side surface (S8).
[0160] A switch (10) according to a fifteenth aspect is any one of the first to fourteenth aspects, further comprising quick-connect terminals (C1, C2) electrically connected to the fixed contacts (3a, 3b).
[0161] According to this aspect, the switch (10) can be easily connected to the electric wire.
[0162] A switch (10) according to a sixteenth aspect is any one of the first to fifteenth aspects, further comprising pillar terminals (PC1, PC2) electrically connected to the fixed contacts (3a, 3b).
[0163] According to this aspect, the switch (10) and the electric wire can be firmly connected.
[0164] The switch device 100 according to the seventeenth aspect comprises a switch (10) according to any one of the first to sixteenth aspects and a mounting frame (8) that holds the switch (10) and can be mounted on a construction surface.
[0165] According to this aspect, by converting the swinging of the operating handle (6) into the movement of the movable contacts (5a, 5b) via the slide member (9) and the reversing handle (4), even if the operating handle (6) is enlarged, an increase in the protrusion of the operating handle (6) can be suppressed, thereby improving the aesthetic appearance. Furthermore, according to this aspect, the movable contacts (5a, 5b) can be reliably moved while improving the aesthetic appearance, thereby improving reliability. Furthermore, since the movable contacts (5a, 5b) and the fixed contacts (3a, 3b) face each other in the predetermined direction, which is the same as the moving direction of the slide member (9), the dimension of the switch device 100 in the predetermined direction can be shortened compared to when the movable contacts (5a, 5b) and the fixed contacts (3a, 3b) face each other in a direction intersecting the predetermined direction.
[0166] The second to sixteenth aspects are not essential components of the switch (10) and can be omitted as appropriate.
