[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0019] Figure 1 This is a functional diagram of a parallel dual-socket power supply connection device provided for an embodiment of this application. Figure 1 As shown, the device includes a coil unit 11, a power-on control circuit 12, and a conduction control circuit 13; wherein:

[0020] The power-on control circuit 12 is connected to the coil unit 11 and is used to control the coil unit 11 to conduct; when the coil unit 11 is conducted, the coil unit 11 will generate a magnetic field.

[0021] A conduction control circuit 13 is provided, one end of which is connected to two sockets and the other end of which is connected to a power distribution unit. The circuit is used to conduct under the magnetic force of the coil unit 11 to connect the two sockets to the power distribution unit.

[0022] The device provided in this application embodiment uses a power-on control circuit 12 to control the coil unit 11 to conduct, so that the conduction control circuit 13 controls the two sockets to connect to the power distribution unit under the magnetic force of the coil unit 11, so that the parallel double sockets can be connected to the power distribution unit and the conduction state is controllable.

[0023] Figure 2 for Figure 1 A schematic diagram of the first circuit of the device shown. Figure 2 As shown, one end of the power-on control circuit 12 is connected to the live wires of the two sockets respectively, and the other end of the power-on control circuit 12 is connected to one end of the coil unit 11, which is used to control the live wires of the two sockets to be in a conductive state with one end of the coil unit 11; wherein, the other end of the coil unit 11 is connected to the neutral wires of the two sockets.

[0024] from Figure 2 As shown in the diagram, one end of the coil unit 11 is connected to the live wires of the two sockets via the power-on control circuit 12, and the other end is connected to the neutral wires of the two sockets. When the power-on control circuit 12 is in the on state, one end of the coil unit 11 is connected to the live wires of the two sockets; when the power-on control circuit 12 is in the off state, one end of the coil unit 11 is disconnected from the live wires of the two sockets.

[0025] When one end of the coil unit 11 is connected to the live wire of the two sockets and the other end of the coil unit 11 is connected to the neutral wire of the two sockets, the coil unit 11 is turned on, thereby achieving the purpose of controlling the coil unit 11 to be turned on by the power-on control circuit 12.

[0026] Please see Figure 2 The conduction control circuit 13 includes a neutral wire branch and a live wire branch; wherein:

[0027] One end of the neutral wire branch is connected to the neutral wires of the two sockets respectively, and the other end of the neutral wire branch is connected to the neutral wire interface of the power distribution unit. Under the magnetic force of the coil unit 11, the neutral wire branch is conductive.

[0028] One end of the live wire branch is connected to the live wires of the two sockets respectively, and the other end of the live wire branch is connected to the live wire interface of the power distribution unit. The live wire branch is turned on under the magnetic force of the coil unit 11.

[0029] In one exemplary embodiment, at least one of the neutral wire branch and the live wire branch can be implemented by a switching device. For example, one end of the switching device is connected to the neutral wires of the two sockets, and the other end of the switching device is connected to the neutral wire interface of the power distribution unit; or, one end of the switching device is connected to the live wires of the two sockets respectively, and the other end of the switching device is connected to the live wire interface of the power distribution unit.

[0030] Figure 3 for Figure 2 The circuit shown is illustrated in the diagram. Figure 3 As shown, the coil unit 11 and the conduction control circuit 13 are integrated into the relay. A weak current is generated by the power-on control circuit 12, which turns on the coil unit 11, generating a strong magnetic field, thus putting the conduction control circuit 13 into a conducting state.

[0031] Please see Figure 3 The coil in the relay has a first connection terminal A1 and a second connection terminal A2; wherein the first connection terminal A1 is connected to the neutral wire of the two sockets, and the second connection terminal A2 is connected to the other end of the power-on control circuit 12, wherein one end of the power-on control circuit 12 is connected to the live wire of the two sockets.

[0032] The relay has two switching devices. One end L1 of the switching device is connected to the neutral wire of the two sockets, and the other end T1 is connected to the neutral wire interface of the voltage distribution unit. One end L2 of the other switching device is connected to the live wire of the two sockets, and the other end T2 is connected to the live wire interface of the voltage distribution unit.

[0033] When the power-on control circuit 12 is in the on state, the coil in the relay is turned on, generating a magnetic field, which turns on the two switching devices in the relay, namely the device connected to the connection terminal L1 and the connection terminal T1 and the device connected to the connection terminal L2 and the connection terminal T2, thereby making the two sockets connected to the power distribution unit.

[0034] Optionally, the power-on control branch includes a power-on switch and an emergency stop switch, wherein the first connection terminal A1 and the second connection terminal A2 in the relay are connected only when both the power-on switch and the emergency stop switch are turned on.

[0035] Optionally, the power-on switch may include, in addition to a switch for controlling the conduction state, an indicator light. One end of the indicator light is connected to the neutral wire of the two sockets, and the other end is connected to the second connection terminal A2. This indicator light is used to indicate whether the two sockets are successfully connected to the power distribution unit. If the indicator light is on, it indicates that current is flowing through the indicator light, confirming that the two sockets are successfully connected to the power distribution unit; otherwise, it indicates that no current is flowing through the indicator light, confirming that the two sockets are not successfully connected to the power distribution unit.

[0036] from Figure 3As shown in the diagram, the relay connects the live wires of the two sockets, which are then connected to the relay coil via an emergency stop switch and a power-on switch. When two 10A plugs are connected through these two sockets, with both the power-on switch and the emergency stop switch closed, the relay coil conducts, allowing the live and neutral wires of both 10A sockets to be connected in parallel to the power distribution unit, thus achieving a power output capacity of 20A.

[0037] Figure 4 for Figure 1 A second circuit diagram of the device shown. Figure 4 As shown, the coil unit 11 includes a first coil and a second coil; wherein one end of the first coil and the second coil are both connected to the neutral wire of a socket, and the other end of the first coil and the second coil are both connected to one end of the power-on control circuit 12.

[0038] The power-on control circuit 12, with one end connected to the live wire of a socket, is used to control the other ends of the first coil and the second coil to be in a conductive state with the live wire of the socket.

[0039] from Figure 4 As shown in the structure, the first coil and the second coil are connected in the same way. Both are connected to the neutral wire of a socket through one end and to the live wire of another socket through the power-on control circuit 12 through the other end, so as to realize the purpose of controlling the coil unit 11 to conduct by the power-on control circuit 12.

[0040] When the power-on control circuit 12 is turned on and both plugs are inserted into the two sockets, both the first coil and the second coil are energized; otherwise, the first coil and the second coil are de-energized. Using this wiring method, the PDU can only be energized when both plugs are simultaneously inserted into the sockets and the power-on switch is closed, ensuring electrical safety and preventing the situation where one plug is energized while the other is also energized.

[0041] Please see Figure 4 The conduction control circuit 13 includes a neutral wire branch and a live wire branch; wherein:

[0042] The neutral wire branch is used to control the connection between the neutral wires of the two sockets and the neutral wire interface of the power distribution unit.

[0043] The live wire branch is used to control the connection between the live wires of the two sockets and the live wire interface of the power distribution unit.

[0044] In an exemplary embodiment, the neutral wire branch includes a first control unit and a second control unit; wherein:

[0045] One end of the first control unit is connected to the neutral wire of a socket, and the other end is connected to the neutral wire interface of the power distribution unit, which is used to control the neutral wire of the socket to be connected to the neutral wire interface of the power distribution unit.

[0046] One end of the second control unit is connected to the neutral wire of another socket, and the other end is connected to the neutral wire interface of the power distribution unit, which is used to control the neutral wire of the other socket to be connected to the neutral wire interface of the power distribution unit.

[0047] In one exemplary embodiment, the fire wire branch includes a third control unit and a fourth control unit; wherein:

[0048] One end of the third control unit is connected to the live wire of a socket, and the other end is connected to the live wire interface of the power distribution unit, for controlling the live wire of the socket to be connected to the live wire interface of the power distribution unit.

[0049] One end of the fourth control unit is connected to the live wire of another socket, and the other end is connected to the live wire interface of the power distribution unit, which is used to control the neutral wire of the other socket to be connected to the live wire interface of the power distribution unit.

[0050] At least one of the first to fourth control units includes a switching device for controlling the conduction of devices connected to both ends of the switching device.

[0051] Figure 5 for Figure 4 The circuit shown is illustrated in the diagram. Figure 5 As shown, the first coil, the first control unit, and the third control unit are integrated into the first relay; the second coil, the second control unit, and the fourth control unit are integrated into the second relay. A weak current is generated by the power-on control circuit 12, causing the first and second coils to conduct, generating a strong magnetic field, which in turn puts the conduction control circuit 13 into a conducting state.

[0052] Please see Figure 5 The first coil of the first relay has a first connection terminal A1 and a second connection terminal A2; wherein the first connection terminal A1 is connected to the neutral wire of a socket, and the second connection terminal A2 is connected to the live wire of another socket through the power-on control circuit 12. Similarly, the second coil of the second relay has a first connection terminal A1 and a second connection terminal A2; wherein the first connection terminal A1 is connected to the neutral wire of a socket, and the second connection terminal A2 is connected to the live wire of another socket through the power-on control circuit 12.

[0053] The first relay has two switching devices. One end L1 of the switching device is connected to the neutral wire of a socket, and the other end T1 is connected to the neutral wire interface of the voltage distribution unit to realize the control function of the first control unit. The other switching device has one end L2 connected to the live wire of a socket, and the other end T2 connected to the live wire interface of the voltage distribution unit to realize the control function of the third control unit.

[0054] The second relay has two switching devices. One end L1 of one switching device is connected to the neutral wire of another socket, and the other end T1 is connected to the neutral wire interface of the voltage distribution unit to realize the control function of the second control unit. One end L2 of the other switching device is connected to the live wire of another socket, and the other end T2 is connected to the live wire interface of the voltage distribution unit to realize the control function of the fourth control unit.

[0055] After the power-on control circuit 12 is turned on and both plugs are inserted into the sockets, the coils in both relays are turned on, generating a magnetic field, which causes the two switching devices in each relay to turn on, namely the device connected to the connection terminal L1 and the connection terminal T1, and the device connected to the connection terminal L2 and the connection terminal T2, thereby enabling the two sockets to be connected to the power distribution unit.

[0056] Optionally, the power-on control branch includes a power-on switch and an emergency stop switch, wherein the first connection terminal A1 and the second connection terminal A2 of the two relays are connected only when both the power-on switch and the emergency stop switch are turned on.

[0057] Optionally, the power-on switch may include, in addition to a switch for controlling the conduction state, an indicator light. One end of the indicator light is connected to the neutral wire of the two sockets, and the other end is connected to the second connection terminal A2. This indicator light is used to indicate whether the two sockets are successfully connected to the power distribution unit. If the indicator light is on, it indicates that current is flowing through the indicator light, confirming that the two sockets are successfully connected to the power distribution unit; otherwise, it indicates that no current is flowing through the indicator light, confirming that the two sockets are not successfully connected to the power distribution unit.

[0058] from Figure 5 As shown in the structure, each relay enables the connection of the live and neutral wires of one socket. Specifically, the first coil, the first control branch, and the third control branch are integrated into the first relay, while the second coil, the second control branch, and the fourth control branch are integrated into the second relay.

[0059] When two 10A plugs are connected through the two sockets, with both the power switch and the emergency stop switch closed, the coils in the two relays are turned on, allowing the live and neutral wires of the two 10A sockets to be connected in parallel to the power distribution unit, thereby achieving a power output capacity of 20A.
