[Housing 5]
The housing 5 is a housing that accommodates the terminal device 7, and a part of the housing 5 is embedded in a structure such as a ceiling or a wall. The housing 5 is a socket housing or a switch housing.

The housing 5 has a handle 10, a reverse handle 40, a coil spring 49a, a switch cover 20, and a body case 30.

The handle 10 has a flat, substantially rectangular shape, and is the front surface of the wiring device switch 1 (the surface on the positive side of the Z-axis). It is arranged on the Z-axis plus direction side. The handle 10 constitutes part of the outer shell of the housing 5 .

In this embodiment, the handle 10 includes a tumbler type handle 10a and a push button type handle 10b. As shown in FIGS. 1A and 2A, the tumbler-type handle 10a is rotatably supported by the switch cover 20 via the reversing handle 40 by connecting it to the reversing handle 40 that can rotate. The tumbler-type handle 10a rotates about the shaft portion 43 of the reversing handle 40 as a rotation axis. As shown in FIGS. 1B and 2B, the push-button type handle 10b is rotatably supported by the switch cover 20. As shown in FIG. The push-button type handle 10b is rotated around the second connection portion 15 by the pressing force.

As shown in FIGS. 1A and 2A, the tumbler-type handle 10a is an intermediate portion in the X-axis direction and has a pair of first connecting portions 11 arranged side by side along the Y-axis direction. there is That is, the pair of first connecting portions 11 are formed on the side surface in the positive Y-axis direction and the side surface in the negative Y-axis direction of the tumbler type handle 10a. The pair of first connecting portions 11 are long and extend in the negative Z-axis direction from the intermediate portion in the X-axis direction in the tumbler-type handle 10a. The pair of first connecting portions 11 are connected to the reversing handle 40 by fitting the pair of second arms 42b of the reversing handle 40 one-to-one.

As shown in FIGS. 1B and 2B, the push-button type handle 10b has a pair of second connecting portions 15 arranged side by side along the Y-axis direction on the positive direction side of the X-axis. there is In other words, the pair of second connection portions 15 are formed on the side surface of the push button type handle 10b in the plus direction of the Y axis and the side surface in the minus direction of the Y axis. The pair of second connection portions 15 are shaft portions provided on the portion on the positive direction side of the X axis in the push button type handle 10b. The pair of second connection portions 15 are inserted into the pair of second shaft support portions 22 of the switch cover 20 one by one, thereby rotatably supporting the push button type handle 10b.

Here, the push button type handle 10b will be described with reference to FIGS. 2B and 4A.

FIG. 4A is a cross-sectional view showing the push-button type handle 10b according to the embodiment, taken along line IVA-IVA in FIG. 1B.

The push button type handle 10 b has a slide cam 16 and a coil spring 19 . That is, when the push button type handle 10b is attached, the slide cam 16 is provided between the reversing handle 40 and the push button type handle 10b.

The slide cam 16 has a slide portion 16a and an inclined cam 16b. The slide portion 16a moves in the Z-axis direction when the push button type handle 10b is pressed or released. Specifically, the slide portion 16a moves in the negative Z-axis direction when the first protrusion 16c presses the second protrusion 16d of the slide cam 16 when the push button type handle 10b is pressed. Further, when the pressing operation is released, the slide portion 16a is pressed by the coil spring 19 and moves in the positive direction of the Z axis. The slide portion 16a is a housing body that is flat in the Z-axis direction and opened toward the reversing handle 40, and houses the inclined cam 16b therein. The sloped cam 16b contacts or separates from the cam mechanism 44 of the reversing handle 40 by moving in the Z-axis direction together with the slide portion 16a. Specifically, the sloped cam 16b has a plate-like shape, and gradually becomes thicker as it approaches the edge on the plus side of the X axis and the edge on the minus side of the X axis, so that the cam mechanism portion of the reversing handle 40 44 and the slope 16b1 which contacts. The sloped cam 16b is a sloped cam mechanism that can move in the X-axis direction within the slide portion 16a by coming into contact with the cam mechanism portion 44 of the reversing handle 40 . In other words, when the push-button type handle 10b is pressed down, the inclined cam 16b contacts the cam mechanism portion 44 of the reversing handle 40, thereby moving the inclined cam 16b in a direction perpendicular to the axial direction of the shaft portion 43 of the reversing handle 40. (X-axis direction). Here, the axial direction of the shaft portion 43 of the reversing handle 40 is substantially parallel to the Y-axis direction.

Therefore, a predetermined gap 16e is secured between the inclined cam 16b and the reversing handle 40.

Further, when the push button type handle 10b is not pressed, a gap 16e is provided between the inclined cam 16b and the cam mechanism portion 44 of the reversing handle 40. Specifically, when the sloped cam 16b moves in a direction perpendicular to the axial direction of the shaft portion 43 of the reversing handle 40, the sloped surface 16b1 of the sloped cam 16b and the cam mechanism portion 44 of the reversing handle 40 come into contact with each other. enlarges the gap 16e between the ramp cam 16b and the reversing handle 40 on the opposite side. More specifically, when the push-button type handle 10b is pressed, when the inclined surface 16b1 of the inclined surface cam 16b on the positive side of the X-axis contacts the cam mechanism portion 44 on the positive side of the X-axis, the cam mechanism portion 44 The slope 16b1 slides on the cam mechanism portion 44, thereby causing the cam mechanism portion 44 to slide in the positive direction of the X axis. Therefore, the gap 16e between the inclined cam 16b and the reversing handle 40 is enlarged on the X-axis negative direction side of the inclined cam 16b. As a result, when the reversing handle 40 rotates, the position of the movable contact 73a of the switching element 70 is changed. Further, when the push-button type handle 10b is released from being pressed, the biasing force of the coil spring 19 arranged between the slide cam 16 and the switch cover 20 pushes up the slide cam 16 in the positive direction of the Z axis. The button-type handle 10b returns to the posture before being pressed. In the coil spring 19 of the present embodiment, the end on the negative Z-axis direction is engaged with the protrusion 27 on the surface of the switch cover 20 on the positive Z-axis direction, and the end on the positive Z-axis direction is a slide cam. 16 is engaged with a convex portion 16g on the surface on the Z-axis negative direction side.

As shown in FIG. FIG. 4C illustrates a case where the inclined surface 16b1 on the negative X-axis direction side of the inclined surface cam 16b and the cam mechanism portion 44 on the negative X-axis direction side are in contact with each other. As shown in FIG. 4D, by the further pressing operation, the inclined surface 16b1 of the cam mechanism portion 44 slides on the cam mechanism portion 44, so that the inclined surface cam 16b slides in the negative direction of the X axis, and the inclined surface cam 16b slides in the X-axis direction. The gap 16e between the inclined cam 16b and the reversing handle 40 expands on the positive side of the axis. At this time, the reversing handle 40 is pushed by the inclined surface 16b1 of the inclined surface cam 16b, so that the swinging portion 41 of the reversing handle 40 rotates clockwise about the shaft center line V of the shaft portion 43. As shown in FIG. Then, the cam mechanism portion 44 on the side of the X-axis plus direction enters the gap 16e without interfering with the slide cam 16, and the coil spring 49a inserted inside the swinging portion 41 of the reversing handle 40 similarly moves toward the shaft portion. It rotates clockwise about the axis V of 43 . Therefore, as shown in FIG. 4A, the movable contact 73a locked to the lower end of the coil spring 49a is also swung and comes into contact with the fixed contact 71a. As a result, the movable contact 73a and the fixed contact 71a are electrically connected, thereby turning the switch ON. When the pressing operation is released, the slide cam 16 is pressed by the coil spring 19 to move in the Z-axis plus direction, and the slide portion 16a is slid in the X-axis plus direction by the cam spring of the slide cam 16 and pressed. The posture before the operation is restored, and the push button type handle 10b also returns to the posture before the pressing operation.

As shown in FIG. 4B, when the push button type handle 10b is pressed while the switch is ON, the push button type handle 10b is connected to a pair of second connection portions 15 formed on the switch cover 20. It rotates with respect to the biaxial support portion 22 . At this time, the first convex portion 16c on the back surface of the push-button type handle 10b (the surface on the negative side of the Z axis) presses the second convex portion 16d of the slide cam 16, thereby causing the slide cam 16 to move toward the negative Z axis. move in the direction Then, the slide cam 16 is pushed by the push-button type handle 10 b to move in the negative direction of the Z axis, and the sloped cam 16 b of the slide cam 16 comes into contact with the cam mechanism portion 44 of the reversing handle 40 . When the inclined surface 16b1 of the inclined surface cam 16b on the positive side of the X-axis contacts the cam mechanism portion 44 on the positive side of the X-axis, the further pressing operation causes the inclined surface 16b1 of the cam mechanism portion 44 to slide on the cam mechanism portion 44. As a result, the slope cam 16b slides in the X-axis plus direction, and the gap 16e between the slope cam 16b and the reversing handle 40 expands on the X-axis minus direction side of the slope cam 16b. At this time, the reversing handle 40 is pushed by the inclined surface 16b1 of the inclined surface cam 16b, so that the swinging portion 41 of the reversing handle 40 rotates counterclockwise with respect to the shaft center line V of the shaft portion 43. As shown in FIG. Then, the cam mechanism portion 44 on the negative side of the X-axis enters the gap 16e without interfering with the slide cam 16, and the coil spring 49a inserted inside the swinging portion 41 of the reversing handle 40 similarly moves toward the shaft portion. It rotates counterclockwise with respect to the axial center line V of 43 . Therefore, the movable contact 73a locked to the lower end of the coil spring 49a is also swung and separated from the fixed contact 71a. As a result, the movable contact 73a and the fixed contact 71a are electrically cut off, and the switch is turned off. When the pressing operation is released, the slide cam 16 is pressed by the coil spring 19 to move in the Z-axis plus direction, and the slide portion 16a is slid in the X-axis plus direction by the cam spring of the slide cam 16 and pressed. The posture before the operation is restored, and the push button type handle 10b also returns to the posture before the pressing operation.

<Effect>
Next, the function and effect of the wiring device switch 1 according to the present embodiment will be described.

As described above, the wired device switch 1 of the present embodiment is a wired device switch 1 that can be attached to either the tumbler type handle 10a or the push button type handle 10b. It has a turnable reversing handle 40 and a switch cover 20. - 特許庁In addition, the reversing handle 40 is arranged between a shaft portion 43 arranged between the handle 10 and the switch cover 20, and between the handle 10 and the switch cover 20, and is closer to the switch cover 20 than the shaft portion 43 (in this embodiment). 2 has a cam mechanism portion 44 positioned at the central portion of the wiring device switch 1 in the X-axis direction.

For example, in a conventional wired device switch, if it is possible to attach either a tumbler type handle or a push button type handle to a single wired device switch, the surface of the tumbler type handle is and the center of rotation of the reversing handle is short, but in the push button type handle, the second distance (height) between its surface and the center of rotation of the reversing handle is long. This is probably because the push-button type handle is provided with a mechanism for converting the pressing operation into the rotating direction of the reversing handle. In this case, since the switch for wiring equipment becomes large-sized, when it is installed embedded in a structure such as a ceiling or a wall, it protrudes greatly from the structure, resulting in an unattractive appearance.

However, according to the present embodiment, by positioning the cam mechanism portion 44 closer to the switch cover 20 than the shaft portion 43, the center of rotation of the reversing handle 40 and the handle 10 can be brought closer.

Therefore, with the wiring device switch 1, designability can be ensured while suppressing an increase in size. In other words, in this wired device switch 1, even if the push button type handle 10b and the tumbler type handle 10a can be attached to one wired device switch 1, the increase in size is suppressed. It is difficult to spoil the design.

In particular, even if the type of the handle 10 is different, the components of the wiring device switch 1 can be shared, so it is possible to suppress an increase in the manufacturing cost of the wiring device switch 1.

In addition, in the wired device switch 1 of the present embodiment, the reversing handle 40 has a fitting portion 42c that fits with the tumbler type handle 10a. The switch cover 20 includes a shaft support portion (first shaft support portion 21) that rotatably supports the reversing handle 40, and a support portion (second shaft support portion 22) that swingably supports the push button type handle 10b. and

According to this, the tumbler type handle 10a or the push button type handle 10b can be attached to the switch cover 20. In other words, one type of switch cover 20 can be used to replace two types of handles, so that parts can be shared in the wiring device switch 1 . As a result, the switch cover 20 can be standardized without having to manufacture the switch cover 20 for each type of handle, so that an increase in the manufacturing cost of the wiring device switch 1 can be further suppressed.

In addition, in the wiring device switch 1 of the present embodiment, the cam mechanism portion 44 of the reversing handle 40 is provided on both sides of the shaft center line V of the shaft portion 43 in the direction perpendicular to the axial direction of the shaft portion 43. there is

According to this, it is possible to attach it to the tumbler type handle 10a and to move the slide cam 16 used in the push button type handle 10b. can be done.

Further, the wiring device switch 1 of the present embodiment is in a state where the tumbler type handle 10a is attached to the wiring device switch 1, and the tumbler type handle 10a is pushed down. 10a and a virtual plane (XY plane) along the surface of the switch cover 20 including the rotation center of the shaft portion 43, and a push button type handle 10b. A hypothetical image along the surface of the switch cover 20 including the surface of the push button type handle 10b and the rotation center of the shaft portion 43 in the state where the push button type handle 10b is not pressed down in the state where the push button type handle 10b is not pressed down. The second distance L2, which is the shortest distance to the plane (XY plane), is substantially equal.

According to this, even if a tumbler-type handle 10a or a push-button type handle 10b is attached to the wiring device switch 1, the wiring device switch 1 is difficult to increase in size. Even if it is attached to a structure, it is difficult to impair the design more reliably.

Further, the wiring device switch 1 of the present embodiment further includes a base to which the switch cover 20 is attached. The base portion has an opening/closing element 70 having a movable contact 73a and a fixed contact 71a.

According to this, even with the tumbler type handle 10a and the push button type handle 10b, by operating these handles 10, the movable contact 73a and the fixed contact 71a can be electrically connected or disconnected. can be

In addition, in the wiring device switch 1 of the present embodiment, the reversing handle 40 swings when either the tumbler type handle 10a or the push button type handle 10b is pressed. a portion 41, a first arm 42a extending in a predetermined direction (Y-axis negative direction) from the swing portion 41, and a pair of second arms 42b provided on both end sides of the first arm 42a. A cam mechanism portion 44 is provided on the first arm 42a. A shaft portion 43 is provided on the pair of second arms 42b.

According to this, the reversing handle 40 can be swung in both the tumbler type handle 10a and the push button type handle 10b. Therefore, the reversing handle 40 is suitable for the wired device switch 1 .

In addition, in the wiring device switch 1 of the present embodiment, the pair of second arms 42b is further provided with a fitting portion 42c that fits with the tumbler-type handle 10a.

According to this, since the fitting portion 42c and the shaft portion 43 can be provided on the pair of second arms 42b, it is possible to suppress the reversing handle 40 from increasing in size.

(Other modifications)
As described above, the wiring device switch according to the present disclosure has been described based on the above embodiments, but the present disclosure is not limited to these embodiments. As long as they do not deviate from the gist of the present disclosure, various modifications that can be conceived by those skilled in the art may also be included within the scope of the present disclosure.

For example, in the wiring device switch 1 according to the present embodiment, the slide cam of the push-button type handle slides along the direction orthogonal to the pressing direction by the pressing operation, but is not limited to this. For example, as shown in FIG. 6, the push button type handle 10b may be a rotary type handle 10c that rotates the reversing handle 40 around the shaft portion 43 by pressing. Here, FIG. 6 is a schematic diagram showing a rotary type handle 10c according to another modification and its operation. The one-dot chain line in FIG. 6 indicates the center line, and the two-dot chain line indicates the inclination of the rotary-type handle 10c with respect to the center line. The rotary type handle 10 c has a pressing operation portion 90 , a plurality of spring portions 91 , and a rotary cam 92 connected to the pressing operation portion 90 via the plurality of spring portions 91 . The pressing operation unit 90 is a button that is directly pressed. The plurality of spring portions 91 are plate springs that support the rotary cam 92 so as to swing with respect to the pressing operation portion 90 . The rotary cam 92 is pressed against the cam mechanism portion 44 of the reversing handle 40 and can swing itself while elastically deforming a part of the spring portions 91 among the plurality of spring portions 91 . For example, as shown in FIGS. 6A and 6B, when the pressing operation portion 90 is pressed, the rotary cam 92 approaches the reversing handle 40 together with the pressing operation portion 90, and the rotary cam 92 moves toward the pair of cam mechanisms in the reversing handle 40. It abuts on one of the cam mechanism portions 44 of the portions 44 . Further, when the pressing operation portion 90 is pressed, the rotary cam 92 presses the pair of cam mechanism portions 44 of the reversing handle 40 as shown in FIG. While rotating clockwise while deforming, the reversing handle 40 rotates counterclockwise. At this time, a gap 93 is formed between the rotary cam 92 and the other cam mechanism portion 44 of the pair of cam mechanism portions 44 by rotating the rotary cam 92 clockwise. As shown in FIGS. 6d and 6e, when the pressure applied to the pressing operation portion 90 is released, the elastic deformation of the spring portion 91 is released, and the posture of the pressing operation portion 90 returns due to the reaction force of the coil spring (not shown). Therefore, the rotary cam 92 is separated from the reversing handle 40 together with the pressing operation portion 90 . Also in such a rotary type handle 10c, since the reversing handle 40 can be rotated, the movable contact 73a and the fixed contact 71a in FIG. 2B can be electrically connected or disconnected.

Also, the wiring device switch 1 according to the present embodiment may have the configuration shown in FIG. FIG. 5 is a cross-sectional view showing a tumbler-type handle 10a1 according to another modification. The tumbler-type handle 10a1 may have a pair of claw-shaped support portions 11d extending toward the switch cover 20 from the back surface (the surface on the Z-axis negative direction side). The pair of support portions 11 d may be connected so as to sandwich and hook the cam mechanism portion 44 of the reversing handle 40 from both sides in the X-axis direction. That is, the pair of support portions 11d may be fitted to the cam mechanism portion 44 of the reversing handle 40, and the cam mechanism portion 44 may have the fitting portion 44b. As described above, in the wiring device switch 1 of the present embodiment, the cam mechanism portion 44 may be further provided with the fitting portion 44b that fits with the tumbler-type handle 10a1. According to this, since the cam mechanism portion 44 can also be used as the fitting portion 44b, there is no need to separately provide the configuration of the fitting portion 44b in the reversing handle 40. Therefore, the size of the reversing handle 40 can be reduced. can be suppressed.

Further, in the wiring device switch 1 according to the present embodiment, the slide cam 16 that moves the push button type handle 10b in the direction perpendicular to the Z-axis direction may be an example of the support portion of the switch cover 20. .

It should be noted that any form obtained by applying various modifications that a person skilled in the art can come up with to the above-described embodiments, or by arbitrarily combining the constituent elements and functions in each embodiment without departing from the scope of the present disclosure. Any form is also included in the present disclosure.
