Abstract

PURPOSE:To obtain a socket adapter of small size and little power consumption by equipping a latch circuit for giving ON signal at a first pulse signal and OFF signal at a second pulse signal and a DC relay circuit for turning ON or OFF a power switch connected with a socket at these signals. CONSTITUTION:When a first pulse signal enters an input terminal 2 from a controller, the contacts 15, 16 of latch relays 4, 6 are ON. As a result, the contact 18 of a DC relay circuit being a power switch is ON and a socket 8 is conducted. Then, when a second pulse signal enters the input terminal 2 from the controller, the contacts 15, 16 of the latch relays 4, 6 are OFF. As a result, the contact 18 of the DC relay circuit is OFF. A socket adapter uses two latch relays driven at DC24v so that a consumed power can be diminished. Also, because the latch relays to be used are of small size, the socket adapter can be miniaturized even if two latch relays are used in the adapter.

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a home bus that is a component of a remote control system such as a home automation system, and a home bus that is placed between an electric device such as a ventilation fan or a lighting lamp. Receives a signal from a controller that inputs a signal to control the electrical equipment either on or off, controls the electrical equipment according to the signal, and transmits the state of the electrical equipment to the controller. Regarding outlet adapters.

[Conventional technology] The conventional technique will be explained using FIG. 4.

This figure is a block diagram of a conventional outlet adapter.

As shown in the figure, the conventional outlet adapter 100 includes an input conversion circuit that inputs and converts a signal from a controller (not shown), and a relay drive circuit 102 that drives a relay according to the signal from the input conversion circuit. , A in which the contact 109 is turned on or off by this relay drive circuit.
When the C latch relay 103 and the contact 109 of this AC latch relay 103 are connected, the AClooV is energized, and the outlet 104 and the contact 1 of the AC latch relay 103 are connected.
and an output conversion circuit 105 that transmits a signal indicating whether or not 09 is connected to the controller.

It is configured to include a power supply section 106 that stably operates the input conversion circuit 101, relay drive circuit 102, etc.

In addition, instead of using a signal from the controller, a switch built into the outlet adapter 100 directly connects the
A manual switch 107 that can operate the C-latch relay 103 is also provided.

It also includes an additional contact 108 to which a person can manually send a signal from the outside to activate the AC latch relay 103.

The operation of the above outlet adapter 100 will be explained.

When a signal is input from the controller, input conversion circuit 1
01, this signal is transmitted to the relay drive circuit 102, and according to the signal, this relay drive circuit 102
The contact 109 of the C latch relay 103 is turned on or off.

When the signal is to activate the electrical equipment connected to the outlet 104, the contacts of the AC latch relay 103 are connected, the AClooV is energized to the outlet) ○4, and the electrical equipment connected to this outlet 104 is in the operating state. become.

and that this electrical equipment is in working condition.

It is transmitted to the controller via the output conversion circuit 105.

Furthermore, if the signal is to stop an electrical device that is in operation, it will have the opposite effect to the above, and the electrical device will stop.

Further, using the manual switch 107 or the additional contact 108, it is possible to activate or deactivate the electrical equipment connected to the outlet 104 in substantially the same manner as described above.

[Problems to be Solved by the Invention] The above-described conventional power outlet adapter uses an AC latch relay, and this AC latch relay is large and cannot be miniaturized, so the outlet adapter itself is also large.

Furthermore, when this outlet adapter is used as a component of a remote control system, there is a problem in that it is difficult to accommodate the outlet adapter in an outlet box due to its large size.

Also, since the AC latch relay operates a 100v switch, it consumes a lot of power.

For this reason, the power consumption of the entire circuit increases, so the transformer needs to be larger, and this is also one of the reasons why this outlet adapter is large.

An object of the present invention is to provide an outlet adapter that is smaller in size and consumes less power than the above-mentioned conventional outlet adapters.

[Means for solving the problem] The above purpose is to provide a launch circuit that compares the ON signal with the first pulse signal and outputs an OFF signal with the second pulse signal, and a launch circuit that receives this signal and connects to the outlet. This can be achieved by using an outlet adapter that includes a DC relay circuit that turns on or off the power switch.

[Operation] When the first pulse signal enters the human input terminal from the controller, the latch circuit is activated and the contacts of the latch circuit are turned on.

As a result, the contact of the DC relay circuit, which is a power switch connected to the outlet, is turned on, and the outlet is energized.

Then, the electrical equipment connected to the outlet is activated.

In addition, since it is a latch circuit, even after the pulse signal disappears,
Each contact remains on.

Next, when a second pulse signal from the controller enters the input terminal, the latch circuit is activated and the contacts of the latch circuit are turned off.

As a result, the contacts of the DC relay circuit, which is a power switch connected to the outlet, are turned off, electricity no longer flows to the outlet, and electrical equipment connected to the outlet is stopped.

From top to bottom: pulse signal generation status, contact 24°23
(15) and 18 connection states are shown.

First, a state in which ACLOOV is not energized to the outlet 8 will be described as a state of the circuit before a signal is input.

In this state, the contacts 23, 24, 15, 16 are at the positions shown by solid lines. Further, the contact 18 is not connected.

In this case, since the contact 15 is located at the position indicated by the solid line, the light emitting diode 54 is lit.

In this case, the contact 24 is turned off (the state shown at T7 in FIG. 3), and then when this pulse signal is cut off, the transistor 26 is turned off.

Then, at the same time that the contact 23 becomes the OFF state (the state shown at T8 in FIG. 3), the contacts 15, 16, and 18 also become the OFF state (
The AClooV flowing to the outlet 8 is cut off, and the electrical equipment connected to the outlet 8 is stopped.

Further, the light emitting diode 54 lights up, and a signal is sent from the output terminal 14 to the controller to inform that the electrical equipment is stopped.

Not an AC latch relay that runs at oV, but a DC24v
Since it uses two latch relays driven by , power consumption can be reduced.

In addition, compared to the AC latch relay, the latch relay used in this embodiment is small, so even if two latch relays are used, the outlet adapter can be made smaller, and its size is, for example, 120 m long, 116 m wide, and 44 m deep. ■It becomes.

Therefore, it can be easily stored in an outlet box.
