【発明の詳細な説明】
この発明は、照明等の負荷に電力を供給する配
電回路に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power distribution circuit that supplies power to loads such as lighting.
従来、この種の配電回路は、各負荷に対応して
それぞれ設けられているスイツチの閉成及び開放
により負荷に対する電力の供給を制御していた。
このような構成の回路は、スイツチの切り忘れに
より、負荷に無駄に電力が供給され続ける欠点が
あつた。 Conventionally, this type of power distribution circuit has controlled the supply of power to the loads by closing and opening switches provided corresponding to each load.
A circuit with such a configuration has the disadvantage that if the switch is forgotten to be turned off, power continues to be supplied to the load in vain.

の消費を防ぐことができる配電回路を提供するこ
とを目的とする。 This invention was made to eliminate the drawbacks of such conventional circuits, and includes a first switch on the power supply side that commonly acts on each load, and a second switch that is individually provided for each load. and a self-holding circuit that holds itself by closing the first switch and releases the self-holding by temporarily opening the first switch, and by supplying power to the load through this self-holding circuit,
Even if the self-holding circuit is not released and unnecessary power is supplied to the load, by temporarily opening the first switch installed on the power supply side, this self-holding circuit is released and the power is wasted. The purpose of this invention is to provide a power distribution circuit that can prevent the consumption of power.

列接続される。 An embodiment of the present invention will be described below with reference to the drawings. In the figure, a power distribution line 3 is connected to a power source 2 via a switch 1. Loads 5-1 and 5-2 are connected to the power distribution line 3 via self-holding circuits 4-1 and 4-2, respectively. Self-holding circuit 4-1
are switch 6 and contact 7, which open when pressed.
A and a coil 7 constituting a relay together with a contact 7a are connected in series, and a switch 8 that is closed by a push operation is connected in parallel to the contact 7a. coil 7
A load 5-1 is connected between the power distribution line 3 and the power distribution line 3. On the other hand, the self-holding circuit 4-2
The switch 6, the contact 9a, and the coil 9 that constitutes the relay together with the contact 9a are connected to the contact 9.
A switch 8 is connected in parallel to a. A load 5-2 is connected in parallel to the coil 9 via a switch 10.

６を一時開路することで得られる。 Next, the operation will be explained. First, load 5-1
When the switch 8 on the load side is closed, the switches 6, 8 and the coil 7
A current flows through the load 5-1 through the relay, and the contact 7a of the relay is closed, so that the self-holding circuit 4-1 performs self-holding. As a result, power from the power source 2 is supplied to the load 5-1. The self-holding circuit 4-1 can be released by temporarily opening the switch 1 on the power supply side or the switch 6 on the load side.
次に負荷５―２に電力を供給する場合におい

ツチ１又は６を開路することによつて得られる。 Next, when power is supplied to the load 5-2, when the switches 8 and 10 of the self-holding circuit 4-1 are closed, current flows through the coil 9 and the contact 9a is closed. , the self-holding circuit 4-2 performs self-holding, and power is supplied to the load 5-1. The self-holding circuit 4-2 can be released by opening the switch 1 or 6.
従つて、負荷側のスイツチ６の開路操作を忘れ

力の供給が遮断される。 Therefore, even if unnecessary power is supplied to the loads 5-1 and 5-2 because the user forgets to open the switch 6 on the load side, the self-maintenance can be maintained by temporarily opening the switch 1 on the power supply side. The self-holding of the circuits 4-1 and 4-2 is released, and the supply of power to the loads 5-1 and 5-2 is cut off.
なお、負荷が螢光灯の場合は、その性質から明
らかなように、一時スイツチ１を開路することに
より、いつでも放電を停止させることができる。 In addition, when the load is a fluorescent lamp, as is clear from its nature, the discharge can be stopped at any time by opening the temporary switch 1.

せることができる。 As described above, according to the present invention, by temporarily opening the switch on the power supply side for confirmation, it is possible to cut off the power supply to all the loads connected to the relevant distribution line. It is possible to prevent unnecessary power consumption due to forgetting to turn off the power. If the self-holding circuit is released on the load side while necessary, power supply can be restarted at will by closing the switch on the load side again.
