Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a timing device.

[Conventional technology] Conventionally, at a preset time or after a preset time,
There are timed devices that operate other electrical devices.

[Problem to be solved] However, the conventional timer described above requires a complicated electric circuit to operate other electrical equipment using the electrical signal output from the timer, making the device expensive. There was a problem.

An object of the present invention is to obtain a timer that can operate other electrical equipment without using complicated electrical circuits.

[Means for Solving the Problems] The timer of the present invention includes an insertion member that is formed by sandwiching an insulating layer between a pair of electrodes and can be inserted into a power circuit section of another electrical device, and a preset time or time. a switch that connects the pair of electrodes of the insertion member to each other when the insertion member is later closed; a pair of connector terminals that contact the pair of electrodes of the insertion member when the insertion member is inserted; and an alarm sound generating device that generates an alarm sound when conduction is established between the pair of connector terminals via the switch in a state where the insertion member is connected to the power supply of the connector terminal or other electrical equipment. It is inserted into a circuit section and controls the alarm sound generating device or other electrical equipment in response to the opening and closing operations of the switch.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

Embodiment 1 First, a first embodiment of the present invention will be explained using FIGS. 1, 2, 4, and 3.

In this embodiment, the timer shown in FIGS. 1, 2, and 4 is used to control a DC electric device.

Figure 1 shows a timer, Figures 2 and 4 show parts of this timer, and Figure 3 shows how the timer is used to control other electrical equipment. This figure shows an example of how it is used.

In FIGS. 1 to 4, reference numeral 1 denotes an alarm clock, and an alarm switch 2 closes at a preset time. Both ends of the switch 2 are connected by lead wires 3, 3 to a pair of electrodes 5, 5 facing each other with an insulating layer 4 interposed therebetween. The electrodes 5, 5 and the insulating layer 4 constitute an insertion member. This insertion member can be inserted into the power supply circuit section of another electrical device, and for example, as shown in FIG. . The alarm clock 1 is provided with an insertion opening 10 for an insertion member.
As shown in FIG. 4, the insertion port 10 is provided with a pair of connector terminals 11 that come into contact with the pair of electrodes 5, 5 of the insertion member when the insertion member is inserted. As shown in FIG. 4, an alarm signal generator 12 and a battery 13 are connected to both ends of the pair of connector terminals 11. This alarm signal generating device 12, transistor 14, and sounding device 15 constitute an alarm sound generating device. As can be seen from FIG. 4, when the switch 2 is closed with the insertion member inserted into the connector terminal 11, conduction occurs between the electrodes of the connector terminal 11 via the switch 2, and an alarm sound is generated.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 to 4.

First, a case where time switching of the electrical equipment 6 is performed using the alarm clock 1 will be described. At this time, after setting the alarm time to a desired time and inserting the insertion member between the battery contact piece 7 and the battery 8 as shown in FIG. 3, the power switch 9 of the electrical equipment 6 is closed. When the switch 2 is closed at a desired time, the electrodes 5, 5 are short-circuited, the battery 8 is supplied to the electric device 6, and the electric device 6 operates.

Next, a case where the alarm clock 1 is used as a normal alarm clock will be explained. At this time, the alarm time is set to a desired time, and the insertion member is inserted into the connector terminal 11 shown in FIG. 4.
When the switch 2 is closed at a desired time, the battery 13 is supplied to the alarm signal generating circuit 12 to generate an alarm signal, and the sound generating device 15 generates an alarm sound. When the insertion member is pulled out, the alarm signal generating circuit 12 becomes inoperable and the sound is stopped. Note that a noise stop switch may be provided separately.

Embodiment 2 Next, a second embodiment of the present invention will be explained using FIGS. 1, 2, 4, and 5.

In this embodiment, the timer shown in FIGS. 1, 2, and 4 is used to control an AC electric device.

FIG. 5 shows an example of an adapter for an AC electric device whose time is controlled using the timer shown in FIGS. 1, 2, and 4. In the figure, 16 is a terminal that is inserted into an AC power outlet, 17 is an AC relay, 18 is an insertion terminal that is normally in contact, 19 is an outlet electrode,
20 is a power plug for an electric device (not shown).

In the above configuration, since the insertion terminals 18 are normally in contact, current flows through the coil 17a of the relay 17 and the contact 17b is closed. Therefore, alternating current is supplied to the outlet electrode 19, and when the plug 20 is inserted, the electrical equipment will operate.

Therefore, when the insertion member is inserted into the insertion terminal 18, if the switch 2 is open, no current flows through the coil 17a, so the contact 17b is opened, and AC power is not supplied to the electrical equipment. Then, when the switch 2 is closed at a desired time, current flows through the coil 17a, the contact 17b is closed, and AC power is supplied to the electrical equipment. With this, time control of AC electric equipment can also be performed. In this case, coil 1
The current flowing through the switch 2 can be suppressed slightly by the impedance of the switch 7a, and a conventional switch with a small current capacity can be used.

Example 3 This example shows another aspect of the insertion member, and will be explained using FIGS. 6, 7, and 8.

In FIGS. 6 and 7, the watch case 21
A housing part 22 is provided in a part of the housing part 22, and an insertion member formed by sandwiching an insulating layer 23 made of an insulating plate between a pair of electrodes 24, 24 is stored in the housing part 22. This insertion member is rotatably fixed by a shaft 25. Reference numeral 26 denotes a connector terminal with spring properties, which does not touch each other when the insertion member is taken out of the storage portion, and connects each electrode 2 when the insertion member is stored.
It comes into elastic contact with 4 and 24. That is, it functions similarly to the connector terminal 11 shown in FIG. 4.

With the above configuration, an alarm is set by storing the insertion member in the storage portion 22, and an alarm sound is generated when the alarm switch (not shown) is closed at a desired time. To stop the noise, take the insertion member out of the storage part 22 and insert the electrode 2.
This can be done by cutting off the contact between 4 and 24 and the connector terminal 26.

When controlling the time of other electrical equipment, the 8th
As shown in the figure, take out the insertion member and insert it between the battery and the battery contact piece. With this, it is possible to perform time control of other electrical devices in the same manner as in the above embodiment.

[Effects] With the timer of the present invention, other electrical equipment can be controlled without requiring a complicated electric circuit.

Furthermore, by inserting the insertion member into the connector terminal of the timer, it is also possible to control the alarm device of the timer itself.
