Description

[Detailed description of the invention] The present invention relates to an adapter for a timing device.

The applicant of the present application previously proposed a general-purpose timing device for an 11-ton pond device in Japanese Patent Application No. 57-250426. This is connected to both ends of an alarm switch, and controls time by inserting an insertion member consisting of a pair of electrodes facing each other through an insulating layer between the battery and battery contact piece of a battery-operated device. be. However, this method has the disadvantage that it is not possible to control the time of AC equipment, and that even battery-powered equipment cannot be time-controlled when using an AC adapter.

Therefore, the present invention is designed so that the timer for battery-powered equipment can also be used for time control of all AC equipment.

An embodiment of the present invention will be described below based on the drawings. 1st
In the figures and FIG. 2, 1 is an alarm clock, and an alarm switch 2, which is a timed switch, closes when a set time comes. Both ends of the alarm switch 20 are lead wires 3
．． 6, the insulating plate 4 is sandwiched therebetween and connected to the opposing electrodes 5.5.

This electrode 5.5 and the insulating plate 4 constitute an insertion member,
As shown in FIG. 5, this is inserted between an α battery 6 and a battery contact piece 7 of a battery-operated device such as a radio (not shown). Therefore, while the alarm switch 2 is open, the battery 6 to the device is
supply has been cut off.

When the alarm switch 2 is closed at the set time, the electrodes 5 and 5 are electrically connected, and the battery 6 is supplied to the device to drive it.

The above timer cannot be used as is to control the time of AC equipment. Therefore, we use Ada 1 in Figure 4, 8a,
8b is a plug terminal that can be inserted into a commercial power outlet (not shown), and 9&.

Reference numerals 9b, 9'b, and 9c are outlet terminals into which the power plug 11 of the AC device 10 is inserted. Reference numeral 12 denotes a connector terminal into which an insertion member is inserted, and is normally not in contact with the connector terminal. Reference numeral 15 denotes a relay, and switch batteries 14 are connected in series to a coil 13a, which is a control element, through a connector 12. Contact 151) of relay 15 is plug terminal 8a
and the outlet terminal 9a. Plug terminal 8a.

abFi are connected to outlet terminals 9c and 9b, respectively.

In the above configuration, under normal conditions, no current flows through the coil 13a and the contact 13b is open. To use the AC device 10 in this state, connect the plug 11 to the outlet terminals 9b and 9.
Use it by inserting it into c.

When controlling the time of the AC device 10, set the alarm time at a desired time and insert the insertion member into the connector terminal 12.
Insert it into the In addition, the plug 11 has outlet terminals 9a, 9
Insert into b. Since the alarm switch 2 is now open, no current flows through the coil 13a, and the contact 15b is open, the AC device 10 does not operate. When the alarm switch 2 closes at the desired time, conduction occurs between the connector terminals 12 and current flows through the coil 13a, causing the contact 15
b closes. Therefore, the AC device 10 is supplied with commercial power and is driven.

FIG. 5 shows an example in which a two-contact relay is used as the relay 15. When no current flows through the coil 15a, the contact 15
b is in the illustrated state, and the outlet terminals 16b and 16c
is supplied with commercial power. At the desired time, the alarm switch closes and current flows through the coil 15a, switching the contact 15b and the outlet terminals 16a, 16b.
Commercial power is supplied to

Therefore, if you want to turn off an AC device at a set time, connect the plug terminal to the set terminal 16b.

16c, and if you want to turn it on at a set time, just plug it into the plug terminals 16a and 16b. - Fig. 6 shows another embodiment, which normally operates as an alarm clock, where the DC terminal is inserted to control the time of battery-powered equipment, and the AC terminal is inserted to control the time of AC equipment. It is something. In the figure, an alarm clock 17 is provided with a jack 18 into which a plug 19 or 20 can be inserted. plug 19
An insertion member similar to that described above is connected to the plug 20, and an adapter 21 is connected to the plug 20. The adapter 21 consists of a plug terminal 22, an outlet terminal 25, a relay 24, and a battery 25.

FIG. 7 shows a part of the circuit configuration of the alarm clock 17, in which 26 is a sounding device, 27 is an alarm signal generation circuit, and 2B is a transistor. 2'9) is an alarm switch, and 50 is a switch that opens when a plug is inserted into the jack 18.

Due to the above configuration, the switch 50 is closed when the junk 18 is not plugged in.
When the alarm switch 29 closes at the set time, the alarm signal generating circuit 27 operates and the sounding device 26 generates an alarm sound. In other words, it functions as an alarm clock.

Therefore, when controlling the time of battery-powered equipment, 1 lag 19
into the jack 18, and insert the insertion member between the battery and battery contact piece of the battery-powered device.

When the plug 19 is inserted K, the switch 30 is opened and the alarm switch 29 is closed, but no alarm sound is generated.

For that Q, there is an alarm switch 29, a jack 18,
Electricity is established between the electrodes of the insertion member through the plug 19, and the device is driven.

Next, when controlling the time of AC equipment, plug 2
0ft jack 18, plug terminal 22 of adapter 6-21 into a commercial power outlet, and plug terminal of an AC device into outlet terminal 23. In this case as well, since the switch 50 is open, no alarm sound is generated even if the alarm switch 29 is closed. on the other hand,
When the alarm switch 29 closes, the relay 24
A current flows through the coil 24a, the contact 24'b closes, and commercial power is supplied to the AC device.

FIG. 8 shows an example in which an AC/DC converter circuit 61 is used as a DC power source in the adapter, and the AC/DC converter circuit 51
The coil 32a of the relay 62 and the connector terminal 66 are connected to the output of the relay 62. The connector terminals 33 are in contact in a normal state. Therefore, in the normal state, the coil 32a
A current flows through the contact 52b, and the contact 52b is closed. Plug terminal 3
4a is connected to the outlet terminal 35a via the contact 52b, and the plug terminal 54b is connected to the outlet terminal 35b. Therefore, under normal conditions, the outlet terminal 55a
, 5! Commercial 1 in lb! Zeng is supplied.

On the other hand, the output of the AC/DC conversion circuit 31 is supplied to a jack terminal 66 via a connector terminal 63.

A DC plug 37 can be inserted into the junk terminal 36,
The plug 68 at the other end is inserted into the jack of an AC adapter (not shown) of a battery-powered device. Therefore, normally 1
! It can operate both pond type equipment and AC equipment.

Therefore, in order to perform time control of the device, an insertion member is inserted into the connector terminal 63. While the alarm switch 2 is open, the connection between the connector terminals 53 is cut off, and the power supply to the jack terminal 56 is cut off. Also, the coil 32a[l
Since the current does not flow, the contact 52b opens, and the power supply to the outlet terminals 55a and 55b is also cut off.

When the alarm switch 2 is turned M at the set time, the connector terminals 53 are electrically connected, the jack terminal 66 and the outlet terminals 55a and 55b are fully supplied with power, and each device is driven.

Figure 9 shows a two-contact relay 5 in place of the relay 32 in Figure 8.
9, one contact 39c of the relay 59 is provided between the plug terminal 54a and the outlet terminal 35a, and the other contact 32b is provided between the AC/DC conversion circuit 61 and the jack terminal 56.

The difference from the example in Figure 8 is that the A C/DC conversion circuit 6
The point is that the power supply from 1 is not through the alarm switch 2 but through the contact 59bf of the relay 69.

Therefore, the t current flowing to alarm switch 2 is relay 5.
Only the current wt (several 10 mA) flowing through the coil 59a of No. 9 is required, and there is no need to flow the current wt (several 100 mA) to the battery-operated equipment as in the example of Fig. 8.
An inexpensive one with a small current capacity can be used as the current capacity.

Although an alarm clock is used as the timer in each of the above embodiments, the present invention is not limited to this, and a timer may be used to activate or deactivate the device after a set time. Furthermore, the relay is not limited to the coil type, but may also be a solid state relay.

As described above, according to the present invention, it is possible to control the time of AC equipment using a timer for battery-powered equipment, and since the timer is driven by an IT battery, even if there is a power outage in the middle, the time or time remains unchanged. Equipment can be driven reliably without shifting.

In addition, if the time switch is configured so that only the current that flows through the control element such as the coil of the relay flows, the current will be low.
An inexpensive one with a small current capacity can be used, and the contact life can be extended.
