Abstract

PURPOSE:To install two controls for supporting respective chambers to operate a timer only when the need arises by a method wherein at least a main switch mechanism, a connection terminal and an adjusting mechanism are housed in a first chamber of a device comprising a case and a lid while a timer and a delay operating mechanism are housed in a second chamber, CONSTITUTION:A second chamber 6 of a device 1 comprising a case 2 and a lid 3 houses a timer 60 and a delay operating mechanism while a first chamber houses at least a main switch mechanism, a connection terminal and an adjusting mechanism. Therefore two controls can be installed in two of wiring devices whose size is standardized as well as the respective controls can have opening/closing functions individually so as to turn ON/OFF respective electric circuits. Thus a timer required for such a switch device with a delay operating mechanism provided can be operated only when the need arises so that durability of the timer 60 can be improved by decreasing the number of timer operations.

It includes a microswitch as an on-off switch that is turned on and off after a predetermined period of time, and a connection terminal for an external electric wire that is electrically connected to the microswitch.

[Problems to be Solved by the Invention] However, in the switch device according to the prior art described above, the timer device is always linked to the operation of the on/off operator, and the on/off operator simultaneously opens and closes two load circuits. Therefore, the timer device always operates even when it is not required to operate. Therefore, the number of activations of the timer device increases, which affects the durability of the timer device and reduces the lifespan of the switch device.

In addition, other conventional examples of this type of switch device include:
Some devices house a switch mechanism and timer device in a box the size of a single wiring device, but that alone can fill up the room, so other necessary parts, such as a switch on-state indicator lamp, are needed. There was no storage space for etc. Therefore, the above-mentioned indicator lamp was installed in a different location, and there was a problem in that the size of the display lamp was actually required to be the size of two wiring devices.

The delay operation element 8 is biased toward the starting protrusion 44a side.

The cam crank 55, the winding lever 56, the timer 60, the movable cam 69, the fixed cam 74, the coil spring 78, the holding plate 80, and the leaf spring 87 constitute a delay operation mechanism.

Next, the operation of this embodiment will be explained.

1 to 8 are diagrams showing a state in which both the main switch mechanism 29 and the delay switch mechanism 54 are turned on.

In the on state of the main switch mechanism 29 in which the main fixed contact 21 and the main movable contact 27 are connected, the common terminal 13 connected to the external electric wire and the fixed terminal 1
4 are electrically connected via the support fitting 22 and the movable contactor 25.

Therefore, in this case, the load connected to the electrical circuit is operating.

From this state, when the protruding side (the left side in FIG. 2) of the main controller 7 is pressed, the main controller 7 will rebound around the support shafts 30a and 30b that are in swingable contact with the bearing portion 3a of the lid 3. Swings clockwise. The posture of the coil spring 28 changes in accordance with the swinging motion of the main controller 7, which causes the movable contact 25 to reverse clockwise, causing the main movable contact 27 to separate from the main fixed contact 21 and switch the main switch. The mechanism 29 is in the OFF state.

At this time, the rocking force of the main controller 7 is initially small and reaches its maximum when the center line of the coil spring 28 and the plane direction of the movable contact 25 coincide, and then gradually decreases as the reversal angle increases. , moderation is provided when the movable contact 25 is reversed. With this moderation, the main operator 7 can be reliably reversed, and the main switch mechanism 29 can be reliably turned off. As a result, the common terminal 13
and the fixed terminal 14 are opened, and power to the load is cut off.

At the same time, since the contact pin 33 comes into contact with the fixed terminal 14, the circuit of the neon tube 31 whose one end is connected to the fixed terminal 14 is connected to the contact pin 33, the spring 34, the wiring pattern of the first printed circuit board 32, and the lead. The common terminal 13 is connected via the wire 32a, the coil spring 28 and the movable contact 25.
connected to. As a result, the neon tube 31 is lit, and the lighting display allows the user to know the position of the switch even if the circuit of the main switch mechanism 29 is in an OFF state.

On the other hand, when turning on the main switch mechanism 29, the right protrusion of the main operator 7 is pressed. This causes the main movable contact 27 to connect to the main fixed contact 21 through the same operation as described above.
, the common terminal 13 and the fixed terminal 14 are closed, and the load of the circuit is energized again.

When turning on the delay switch mechanism 54, the right protrusion of the delay operator 8 is pressed. As a result, the cover body 3 swings clockwise about the support shafts 42a and 42b that are in swingable contact with the bearing portion 3b of the lid body 3. At this time, the pressing part 44b of the delay operator 8 pushes down the hoisting lever 56, and the arm 6
The spring compression part 66 provided at the tip of the leaf spring 5 compresses the coil spring 78, and the locking part 67 laterally presses the claw part 81 of the holding plate 80, causing the holding plate 80 to resist the biasing force of the plate spring 87. Then, the locking portion 67 is locked with the claw portion 81 by retreating.

At the same time, as shown in FIG. 5, the sector gear 64 of the winding lever 56 rotates the pinion 68 provided on the rotating shaft 63 counterclockwise, thereby winding up the timer 60. moreover,
As the rotating shaft 63 rotates, the fixed cam 74 is rotated by the same angle. This completes the preparation for operation of the delay switch mechanism.

Next, when the protruding side (left side in FIGS. 3 and 4) of the delay switch mechanism 54 is pressed to turn off the delay switch mechanism 54, the starting protrusion 44a presses the pressure receiving part 82 of the holding plate 80 from below, causing the corresponding The holding plate 80 is retreated outward against the spring force of the leaf spring 87, and the locking portion 71 of the hoisting lever 56 by the claw portion 81 is released. As a result, the spring force of the coil spring 78 acts to rotate the winding lever 56 counterclockwise, but the force that resists this rotational force is applied to the timer 6.
Since the winding lever 56 operates from zero, the winding lever 56 rotates counterclockwise at a predetermined speed set by the timer 60.

When the winding lever 56 rotates counterclockwise in this way,
Since the pinion 68 that meshes with the sector gear 64 rotates clockwise, the fixed cam 74 rotates simultaneously with the rotating shaft 63 that is integrated with the pinion 68, gradually rotating the movable cam 69. At this time, the spring force of the movable spring 39 is always acting on the cam crank 55 so as to urge it upward, and the tip of the crank portion 59 is in sliding contact with the cam surface 70 of the movable cam 69 due to the urging force.

Subsequently, the movable cam 69 rotates by a predetermined angle, and the V-groove portion 7
When the tip of the crank part 59 enters into the lever part 58
As the movable spring 39 moves upward, the contact side of the movable spring 39 moves upward due to its elasticity.

As a result, the delay movable contact 52 is separated from the delay fixed contact 53, and the delay switch mechanism 54 is turned off. Therefore, the time from when the delay operator 8 is turned on to when the delay switch mechanism 54 is turned off becomes the delay time, and the circuit is energized only during the delay time, and after the predetermined delay time, the circuit is turned off. Power to the circuit is cut off.

In addition, in the above embodiment, an example was explained in which a container having a size in which two standardized wiring devices were connected was used, but the present invention is not limited to this, and the case in which three wiring devices were connected was used. It goes without saying that the present invention can be applied to vessels of a larger size than those connected together.

[Effects of the Invention] As explained above, since the present invention is configured as described above, two wiring devices with standardized sizes can be used.
Two operators can be installed in each unit, and each operator can be provided with an individual opening/closing function so that each electric circuit can be turned on and off individually. Therefore, the timer required for this type of switch device equipped with a delay operation mechanism can be operated only when necessary, reducing the number of times the timer operates and improving the durability of the timer. The effect is that the lifespan can be significantly extended.

In addition, the operating status of a ventilation fan, etc. that acts as a load on the delay switch can be determined by the light-emitting display of the light emitting diode built into the delay switch, so even if the operating status of the load is difficult to discern visually, the operating status of the load can be determined. Another advantage is that the operating state can be easily checked using the delay operator.
