C2 is a capacitor that passes the transmission frequency f1 of the connection signal transmission circuit 12.

周波数ｆ０の商用交流電源１は２の配電遮断器に入力、前記配電遮断器２の負荷側より、４は主電源スイッチ（ＳＷ０）、３は電源コンセント、５は通電時の表示灯である。 A commercial AC power source 1 having a frequency f0 is input to a distribution breaker 2, and from the load side of the distribution breaker 2, 4 is a main power switch (SW0), 3 is a power outlet, and 5 is an indicator lamp when energized.

また商用交流電源１より２０の離脱検知受信装置を設けて、その構成は、発信周波数ｆ１がＣ１のコンデンサーを通過する。２２は前記発信周波数ｆ１を受信する接続信号受信装置２０、２３は信号識別回路で信号識別回路２３の出力側と接続する２４の警報制御回路からなる。警報制御回路２４の出力信号を受けて警報を発生する２５の警報装置。なお、２１は受信回路用電源回路である。
また、コンデンサーＣ１とＣ２はＣ１＝Ｃ２、１／２πｆ１Ｃ１＜＜１／２πｆ０Ｃ１である。
ただし、ｆ０は商用交流電源の周波数、ｆ１は接続信号の周波数でる。In addition, 20 disconnection detecting and receiving devices are provided from the commercial AC power supply 1, and the configuration thereof passes through a capacitor having a transmission frequency f1 of C1.

Capacitors C1 and C2 are C1 = C2, 1 / 2πf1C1 << 1 / 2πf0C1.
However, f0 is the frequency of the commercial AC power supply and f1 is the frequency of the connection signal.

３０は負荷の電気自動車で、３２は電気自動車の車充電装置、３３は車充電地で３１は前記給電電源端子１５と接続する受電端子である。 Reference numeral 30 denotes a load electric vehicle, 32 denotes a car charging device for the electric car, 33 denotes a car charging place, and 31 denotes a power receiving terminal connected to the power supply terminal 15.

したがって、以上の構成により負荷に電気自動車３０を例として説明する。
充電池３３に充電をおこなうため、商用交流電源１の主電源スイッチ４をオフの状態にして、差込コネクタ１６よりのコード端一方の離脱検知コンセント１０の給電電源端子１５を電気自動車３０の受電端子３１に接触させると、同時に接触ボタン１４が押され接触検知スイッチ１３がオン状態となり発信回路用電源回路１２の動作スタンバイ状態となる。
ここで、コードの一端の差込プラグ１６を電源供給の商用交流電源装置１の電源コンセント３に接続をして、主電源スイッチ４をオンにすることで、表示灯５が点灯する。Therefore, the electric vehicle 30 is described as an example of the load with the above configuration.
In order to charge the rechargeable battery 33, the main power switch 4 of the commercial AC power supply 1 is turned off, and the power supply power supply terminal 15 of the disconnection detection outlet 10 at one end of the cord from the plug connector 16 is received by the electric vehicle 30. When the contact is made with the terminal 31, the contact button 14 is pressed at the same time, the contact detection switch 13 is turned on, and the power supply circuit 12 for transmitting circuit is in an operation standby state.

The transmission frequency f1 passes through C2, passes through the code 17, passes through C1 in the disconnection detection receiver 20, and is input to the connection signal receiving circuit 22. However, the frequency f0 of the commercial AC power supply 1 is determined by the capacitors C1 and C2. Cut.
The connection signal receiving circuit 22 receives the transmission frequency f1 and sends a control signal to the signal identification circuit 24. The signal identification circuit 24 recognizes the connection state.

いま、主電源スイッチ４をオフにせず、差込プラグ１６を差込中、充電中であっても、充電が完了であっても、受電端子３１より離脱検知コンセン１０、あるいは差込プラグ１６を抜いたり、コードの切断、または接触不良のトラブルが発生すると、発信回路用電源回路１２の電力がオフとなることから接続信号発信回路１１の発信が停止することで、離脱検知受信装置２０の接続信号受信回路２２、及び信号識別回路２４によって接続信号の不通を検知して、警報制御回路２３より警報信号を出力し、警報放置２５より警報音を発する。 Even if the main power switch 4 is not turned off and the plug 16 is being plugged in, being charged, or charged, the disconnection detection outlet 10 or the plug 16 can be connected from the power receiving terminal 31. When disconnection, cord breakage, or contact failure occurs, the power of the power supply circuit 12 for the transmission circuit is turned off, and the transmission of the connection signal transmission circuit 11 is stopped. The signal reception circuit 22 and the signal identification circuit 24 detect the disconnection of the connection signal, the alarm control circuit 23 outputs an alarm signal, and the alarm neglect 25 generates an alarm sound.

以上のことから、屋外の条件かにおいて電気的トラブルや、悪戯、車の盗み等の重大な事においても対応できるものである。
なお、通常の取外しにおいては、電源スイッチ４をオフにすることで、発信電源回路１２の二次電源がオフとなり、接続信号発信回路１１の動作は停止をしておこなうものである。From the above, it is possible to cope with serious problems such as electrical troubles, mischief, and car theft under outdoor conditions.
In normal removal, the secondary power supply of the transmission power supply circuit 12 is turned off by turning off the power switch 4, and the operation of the connection signal transmission circuit 11 is stopped.
