DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 In an embodiment of the utility model, an intelligent circuit breaker includes a circuit breaker housing 1, and an automatic opening and closing component 2 is movably connected to one side of the circuit breaker housing 1;

[0031] The automatic opening and closing assembly 2 has an operating lever 21 and a rotating disk 22. The operating lever 21 and the rotating disk 22 are integrated, and the operating lever 21 penetrates the outside of the circuit breaker housing 1 and has a certain movable space.

[0032] The rotating disk 22 is provided with a 1 / 3 gap, and the rotating disk 22 is movably connected to the circuit breaker housing 1 through a rotating shaft;

[0033] The turntable 22 is movably connected with a fastener 23 below the 1 / 3 notch; the lower end of the fastener 23 is buckled with one end of the driving member 4;

[0034] A cam 24 is provided at a 1 / 3 notch of the rotary disk 22 . The cam 24 is mounted on the output shaft of a stepper motor 25 . The stepper motor 25 is fixed in the circuit breaker housing 1 and is electrically connected to a control panel 26 .

[0035] More specifically, the control board 26 in the present invention uses an Internet of Things circuit board, which may be, but is not limited to, an A20B-8100-0671 circuit board, through which the control board 26 can be wirelessly connected to a mobile phone.

[0036] In this embodiment, the driving member 4 is movably connected to the circuit breaker housing 1 through a rotating shaft, and a tension spring 5 is buckled below one end of the connecting fastener 23 of the driving member 4; the other end of the tension spring 5 is buckled with a movable hook 6; the movable hook 6 is movably buckled with the movable ears on both sides of the bimetallic strip 7 and is movably connected.

[0037] By adopting the above technical solution, when the circuit breaker is opened by controlling the mobile phone terminal, the stepper motor 25 drives the cam 24 to rotate clockwise, and the cam 24 pushes the turntable 22 to rotate counterclockwise at the 1 / 3 gap. At this time, the buckle 23 under the turntable 22 loses the pulling force on the driver 4, and the tension spring 5 tightens one end of the driver 4 according to its own elastic force, so that the end of the driver 4 resting on the bimetallic strip 7 deflects upward and contacts the power-carrying sheet 11; at this time, the incoming terminal 17, the incoming terminal metal sheet 16, the power-carrying sheet 11, the driver 4, the C-shaped lever 9 and the outgoing metal sheet 10 form a passage, thereby realizing the remote opening of the circuit breaker.

[0038] In this embodiment, one end of the bimetallic strip 7 is inserted into the plastic plate arranged at the lower end of the arc extinguishing grid 13, and the lower end of the bimetallic strip 7 is fitted and connected with a steel strip 8; a C-shaped lever 9 is provided at the bottom of the steel strip 8, and the upper end of the C-shaped lever 9 is buckled on one end of the driving member 4.

[0039] More specifically, the bottom of the C-shaped lever 9 is connected with a wire outlet metal sheet 10, which is located above the wire outlet of the circuit breaker, and a wire outlet terminal bolt hole 19 is vertically provided on one side of the wire outlet of the circuit breaker.

[0040] By adopting the above technical solution, when the circuit breaker is remotely closed, the stepper motor 25 drives the cam 24 to rotate counterclockwise, and the cam 24 pushes the turntable 22 to rotate clockwise at the 1 / 3 gap. The turntable 22 lifts one end of the driving member 4 through the fastener 23 below. At this time, the other end of the driving member 4 is separated from the power-on sheet 11, thereby realizing the remote closing function.

[0041] In this embodiment, a fixing plate 14 is provided above one end of the driving member 4 connected to the C-shaped lever 9 , and an overload protection component 15 is connected to the fixing plate 14 . The coil 12 is sleeved on the outside of the overload protection component 15 .

[0042] Specifically, the overload protection assembly 15 includes an iron cylinder with a pin fixed at the bottom of the iron cylinder; a spring is provided outside the pin and fixed on the fixing plate 14; and the bottom of the pin passes through the bottom of the fixing plate 14.

[0043] By adopting the above technical solution, when the current is too large, the coil 12 will form a strong magnetic field. Under the influence of the strong magnetism, the iron cylinder compresses the spring downward. At this time, the lower end of the pin is abutted against one end of the driver 4, and forces the driver 4 to flip over, so that the driver 4 is separated from the electric sheet 11, thereby realizing the overload self-protection function.

[0044] In this embodiment, two ends of the coil 12 are respectively connected to the power supply sheet 11 and the incoming line metal sheet 16 , wherein the power supply sheet 11 is connected to the arc extinguishing grid 13 .

[0045] By adopting the above technical solution, a large number of arcs will be generated at the moment when the power-carrying piece 11 is separated from the driving member 4. We connect the power-carrying piece 11 with the arc-extinguishing grid 13, and the arc can be extinguished by the arc-extinguishing grid 13, thereby realizing the protection of the circuit breaker.

[0046] In this embodiment, the incoming line metal sheet 16 is located below the incoming line terminal 17 , and an incoming line bolt hole 18 is vertically opened on one side of the incoming line terminal 17 .

[0047] In this embodiment, a card slot is provided on the rear side of the circuit breaker housing 1, and a card connector 20 is movably connected to the bottom side of the card slot.

[0048] The working principle of the utility model is as follows: when the circuit breaker is opened by controlling the mobile phone terminal, the stepper motor 25 drives the cam 24 to rotate clockwise, and the cam 24 pushes the turntable 22 to rotate counterclockwise at the 1 / 3 notch. At this time, the buckle 23 under the turntable 22 loses the pulling force on the driving member 4, and the tension spring 5 tightens one end of the driving member 4 according to its own elastic force, so that the end of the driving member 4 resting on the bimetallic strip 7 deflects upward and contacts the power-carrying sheet 11; at this time, the incoming terminal 17, the incoming terminal metal sheet 16, the power-carrying sheet 11, the driving member 4, the C-shaped lever 9 and the outgoing metal sheet 10 form a passage, thereby realizing the remote opening of the circuit breaker;

[0049] When the circuit breaker is remotely closed, the stepper motor 25 drives the cam 24 to rotate counterclockwise, and the cam 24 pushes the turntable 22 to rotate clockwise at the 1 / 3 gap. The turntable 22 lifts one end of the driving member 4 through the buckle 23 below. At this time, the other end of the driving member 4 is separated from the power-carrying sheet 11, thereby realizing the remote closing function;

[0050] When the current is too large, the coil 12 will form a strong magnetic field. Under the influence of the strong magnetism, the iron cylinder compresses the spring downward. At this time, the lower end of the pin is pressed against one end of the driver 4, forcing the driver 4 to flip over, so that the driver 4 is separated from the electric sheet 11, thereby realizing the overload self-protection function.

[0051] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
