Alternatively, the microprocessor 41 may determine the connection mode of the second loop after a preset time period, instead of determining the connection mode of the second loop every preset time period, regardless of the connection condition of the receptacle 20, based on the time when the first loop is connected as the starting point of the timing.

In the present embodiment, the preset rules include, but are not limited to, three-wire five-wire, three-zero four-wire, and two-three-wire connection rules for three-stage box connection. In an alternative embodiment, the first socket 20a is connected to the first phase line 51 of the power inlet and the signal input pin 1, the second socket 20b is connected to the second phase line 52 of the power inlet and the signal input pin 2, the third socket 20c is connected to the third phase line 53 of the power inlet and the signal input pin 3, the fourth socket 20d is connected to the neutral line 54 of the power inlet and the signal input pin 4, and the fifth socket 20e is connected to the ground line 55 of the power inlet and the signal input pin 5. For a three-phase five-wire system, namely a wiring mode that a three-phase live wire, a one-phase zero wire and a one-phase ground wire are all required to be connected, if the input signals of the signal input pins 1-5 are all 1, namely the first socket 20a to the fifth socket 20e are all connected, the wiring mode is judged to be in accordance with a preset wiring specification; for a three-phase zero-free four-wire system, namely a wiring mode in which a three-phase live wire and a one-phase ground wire need to be connected, if the input signals of the signal input pins 1, 2, 3 and 5 are all 1, namely the first socket 20a, the second socket 20b, the third socket 20c and the fifth socket 20e are connected, judging that the wiring mode meets a preset wiring specification; for two-phase three-wire system, that is, the connection mode in which the two-phase live wire and the one-phase ground wire need to be connected, if the input signal of the signal input pin 1, 2, 5 or 2, 3, 5 or 1, 3, 5 is 1, that is, the first socket 20a, the second socket 20b and the fifth socket 20e, or the second socket 20b, the third socket 20c and the fifth socket 20e, or the first socket 20a, the third socket 20c and the fifth socket 20e are connected, it is determined that the connection mode meets the preset connection specification; except the above wiring method, and all the sockets 20 are not connected to the signal input pins of the microprocessor 41, the other wiring methods are judged as illegal wiring. The preset wiring rule is mainly characterized in that when the wiring detection circuit is used for connecting the three-stage box with an electric appliance, the wiring mode is judged, if the detection circuit is applied to detection of other circuit connection, resetting or corresponding adjustment can be carried out according to specific wiring conditions, and the specific setting and the corresponding principle are similar to the preset wiring rule for setting the three-stage box.

If the microprocessor 41 compares the on state of the connected outlet 20 with the preset connection rule in the preset rule, and finds that the on state of the connected outlet 20 is not in accordance with the preset connection rule, that is, there is a misconnection or misconnection in the connection of the connected second loop, the microprocessor 41 controls the relay 43 to disconnect all the second loops.

Referring to fig. 5, in a preferred embodiment, the power inlet 50 is connected to the inlet connection point 29 of the second connection site 23 of the socket 20 through the relay 43. The power inlet wire 50 is connected with the relay 43 first and then connected with the socket 20, so that the connection on-off of the power inlet wire 50 and the socket 20 is controlled by the relay 43, the on-off of the relay 43 is controlled by the microprocessor 41 according to the on-off condition of the second loop, and the purpose of controlling the wiring mode of the electric appliance through the detection circuit is achieved. The relay 43 may be configured to be in a normally closed state, and if the connection of the second circuit does not conform to the preset connection rule, the microcontroller controls the relay 43 to be disconnected, so that the second connection position is disconnected from the power inlet line 50. Alternatively, the relay 43 may be of a break type, two contacts of the relay 43 are closed when the coil is not energized, and the two contacts are opened after the coil is energized, and the specific control current may be selected according to actual conditions. Optionally, after the microprocessor 41 determines that the connection of the second loop does not meet the preset wiring specification, a control signal is always output to the relay 43, so that the relay 43 is kept in a disconnected state, and the power inlet wire and the socket are disconnected; until the microprocessor 41 determines that the connection of the second loops meets the preset wiring rule or all the second loops are in the off state, that is, all the sockets 20 are not connected to the electrical appliance inlet wire 30, the microprocessor 41 stops outputting the signal for controlling the relay 43 to keep the off state, so that the switch of the relay 43 is closed, and the electrical appliance inlet wire is connected to the sockets.

Alternatively, if the relay 43 is configured to be in a normally open state, the microprocessor 41 controls the relay 43 to be closed when it is determined that the second circuit is on and the wiring state of the second circuit meets the preset wiring rule, otherwise, the relay 43 is opened.

Referring to fig. 6, in a preferred embodiment, the connection detecting circuit 40 further includes an alarm 47, and the alarm 47 is connected to a signal output pin of the microprocessor 41 and the negative terminal of the power supply. When the microprocessor 41 determines that the second circuit connected to the outlet 20 is erroneously connected based on the connection information of the outlet 20, it simultaneously sends control signals to the relay 43 and the alarm 47 to control the relay 43 to be disconnected and the alarm 47 to alarm, respectively. Alternatively, the alarm 47 may be an audible and visual alarm, which sends an alarm sound and performs light flashing and the like to alarm when receiving an alarm signal, and notifies a wiring person to adjust the wiring so that the wiring conforms to the wiring specification.

Referring to fig. 7, fig. 7 is a schematic diagram of a connection detecting circuit according to an embodiment of the present disclosure. In a preferred embodiment, the wiring detection device 100 includes a wiring detection circuit 40, a plug 10, and a receptacle 20. In this embodiment, the electrical appliance incoming line 30 includes five-phase cables, which are a first-phase live line 31 of the electrical appliance incoming line, a second-phase live line 32 of the electrical appliance incoming line, a third-phase live line 33 of the electrical appliance incoming line, a zero line 34 of the electrical appliance incoming line, and a ground line 35 of the electrical appliance incoming line, and each phase cable is connected with one of the pins 10. The power inlet 50 is also configured as five phases, which are a first phase live wire 51 of the power inlet, a second phase live wire 52 of the power inlet, a third phase live wire 53 of the power inlet, a zero line 54 of the power inlet, and a ground wire 55 of the power inlet, and each phase cable is connected to one socket 20, for concrete correspondence, see fig. 6. The two connection terminals 22 (see fig. 2 in particular) of the first connection site 21 of each socket 20 are respectively connected to two terminals of the connection detection circuit 40. The wiring detection circuit 40 is connected with a relay 43, the closing and the opening of the relay 43 are controlled by the wiring detection circuit 40, and the power inlet wire 50 is communicated with the socket 20 through the relay 43.

After the plug 10 is inserted into the socket 20 according to the plug insertion direction 60, while the corresponding phase of the electrical appliance inlet wire 30 is connected to the corresponding phase of the power inlet wire 50 connected to the socket 20 to form a second loop, the first contact portion 11 (see fig. 1a specifically) of the plug 10 conducts the two connection ends 22 of the first connection position 21 of the socket 20, so that the connection lines of the connection line detection circuit 40 connected to the two connection ends 22 are conducted to form a first loop. The connection detection circuit 40 can know the specific connection condition of the second circuit according to the connection state of the first circuit, so as to judge whether the connection mode of the second circuit is illegal, and control the relay 43 according to the judgment result. If the connection mode of the second loop is irregular, the connection detection circuit 40 will control the relay 43 to disconnect the power supply 50 from the socket, so as to cut off the power of the electrical appliance connected to the plug 10. Potential safety hazards caused by non-standard wiring or damage to electrical appliances are prevented.
