Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-8 As shown, the utility model provides the following technical solutions:

[0024] An Internet of Things residual current operated circuit breaker includes a circuit breaker device, an electrode 6 is provided on the circuit breaker device, and a connector 5 is also installed on the circuit breaker device. A hollow cavity is formed inside the connector 5, and a conductive plate 512 is fixedly connected to the cavity. One end of the electrode 6 extends into the cavity and contacts the conductive plate 512.

[0025] Through the above technical solution, when a person needs to control the circuit, the wire at one end of the circuit is placed in the cavity inside the connector 5, and the end of the wire is in contact with the conductive plate 512 inside the cavity, and the wire at the other end of the circuit is placed in the cavity inside the corresponding connector 5, and the end of the wire is in contact with the conductive plate 512 inside the cavity. According to the above steps, the corresponding wire is in contact with the conductive plate 512, so that a single electrode 6 can be connected to multiple wires, so that the device is easy to connect the number of wires required by the person for control, and automatically cuts off the power supply when the circuit breaker detects that the residual current in the line reaches a preset threshold.

[0026] Specifically, in one embodiment, regarding the above-mentioned connector 5, the connector 5 includes a protective shell 51, the top of the protective shell 51 is open to form an inner cavity 511, and the bottom of the protective shell 51 is open to form a socket 510 matching the electrode 6, the conductive plate 512 is fixedly connected to the inside of the inner cavity 511, one side of the protective shell 51 is fixedly connected to the side frame 53, one side of the side frame 53 is rotatably connected to the connecting plate 54, and one side of the connecting plate 54 is fixedly connected to the cover plate 52.

[0027] In this embodiment, when personnel need to connect the device to the wire, the connector 5 is placed on the circuit breaker device, and the electrode 6 on the circuit breaker device is inserted into the socket 510 on the protective shell 51, so that the electrode 6 is connected to the protective shell 51, and the electrode 6 is connected to the conductive plate 512. The cover plate 52 is pulled to rotate the cover plate 52 around the protective shell 51 until the cover plate 52 rotates to the maximum opening angle, so that the inner cavity 511 on the protective shell 51 is exposed, and then the end of the wire is placed inside the inner cavity 511, and the wire is in contact with the conductive plate 512 inside the inner cavity 511. The cover plate 52 is pulled, and the cover plate 52 is rotated back to the initial position through the cooperation of the connecting plate 54 and the side frame 53, thereby completely covering the conductive plate 512.
