When the sealing seats fixed on the side surfaces of the shutdown device housing cooperate with the sealing covers, they can firmly fix the wires, preventing moisture in the air from entering the shutdown device housing through the wire-passing holes, thus affecting the operation and safety performance of the shutdown device body, improving its service life, facilitating quick disassembly and assembly of the cover plate, and improving the convenience of maintenance and replacement of the shutdown device body.

[0004] Based on the aforementioned existing technologies, current intelligent circuit breakers designed to prevent misconnection still have the following problems: photovoltaic DC systems have high voltage and large current, and reverse polarity connection is one of the most common and dangerous errors in installation and maintenance. Traditional circuit breakers or junction boxes typically only use color-coded terminals, making it easy for installers to accidentally reverse the positive and negative terminals. Therefore, this invention provides an intelligent circuit breaker designed to prevent misconnection. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent circuit breaker that prevents misconnection. This solves the following problems with existing intelligent circuit breakers: Photovoltaic DC systems have high voltage and large current, and reverse polarity connection is one of the most common and dangerous errors during installation and maintenance.

[0026] Please see Figures 1-5This utility model provides a technical solution:

[0027] The anti-misinsertion intelligent circuit breaker includes a circuit breaker body 1. Both the front and rear ends of the circuit breaker body 1 are equipped with intelligent mechanisms 2 for detecting the insertion status of the interface. The intelligent mechanism 2 includes:

[0028] The connection unit 21 is located on the front side of the switch body 1 and is used to connect the switch body 1 with multiple external devices.

[0029] The judgment system unit 22 is located at the front end of the switch body 1, including a circuit board 221, and a polarity detection module 224 and a control module 225 are provided on the circuit board 221. The polarity detection module 224 and the control module 225 are electrically connected. The polarity detection module 224 detects the polarity of the connection port voltage and the control module 225 determines whether the connector is connected correctly.

[0030] In this embodiment, the judgment system unit 22 further includes an LED driver module 227 and an LED lamp 222. The LED driver module 227 and the LED lamp 222 are respectively disposed above and below the circuit board 221 and electrically connected to the control module 225. When the connector is correctly inserted, the control module 225 controls the LED driver module 227 to drive the LED lamp 222 to light up a green light. When the green light reaches a time threshold, the green light automatically turns off. When the connector is incorrectly inserted, the LED lamp 222 remains on a red light.

[0031] The polarity detection result is fed back to the control module in real time, triggering an alarm sound or a visual confirmation LED green light, achieving millisecond-level error response.

[0032] In this embodiment, the judgment system unit 22 further includes a buzzer driver module 226 and a buzzer 223. The buzzer driver module 226 and the buzzer 223 are disposed above the circuit board 221 and electrically connected to the control module 225. When the connector is correctly inserted, the buzzer 223 does not start. When the connector is incorrectly inserted, the control module 225 controls the buzzer driver module 226 to start the buzzer 223 to issue an alarm.

[0033] In this embodiment, the connection unit 21 includes ten slots 211 respectively opened at the front and rear ends of the switch body 1. Positive terminal 212 and negative terminal 213 are fixedly installed inside the slots 211, and the positive terminal 212 is red and the negative terminal 213 is black.

[0034] The use of red and black colors visually indicates polarity, reducing the probability of human error in wiring.

[0035] In this embodiment, the LED light 222 is inserted into the slot 211 to illuminate the inside of the slot 211 as a notification.

[0036] Each slot is equipped with an independent LED light, which illuminates green when the wiring is correct, quickly locking the interface in place.

[0037] In this embodiment, a transparent cover 214 is fixedly installed on the front side of the slot 211, and the transparent cover 214 is made of transparent acrylic material to allow light to pass through the inside of the slot 211.

[0038] In this embodiment, a sound-transmitting hole 3 is provided on the top front side of the switch body 1 for sound to be transmitted out of the interior of the switch body 1.

[0039] The sound-through hole amplifies the volume of the buzzer 223, ensuring that the alarm sound is identifiable in noisy environments.

[0040] In this embodiment, a handle 4 is fixedly installed on the right side of the switch body 1 for lifting the switch body 1.

[0041] The handle design simplifies equipment movement and installation, improving operational efficiency.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, firstly, the positive terminal 212 and the negative terminal 213 are inserted into the external device. The polarity detection module 224 detects whether the voltage polarity connected to each set of red and black terminals is correct. If correct, the correct signal is transmitted to the control module 225. The control module 225 controls the LED driver module 227 to start, and the LED driver module 227 controls the LED light 222 to light up green. The buzzer 223 does not start. When the set time threshold is reached, the LED driver module 227 transmits a signal that the lighting time has ended to the LED driver module 227. The control module 225 then controls the LED driver module 227 to turn off the LED light 222.

[0044] When an error occurs, the polarity detection module 224 transmits the error signal to the control module 225. The control module 225 then controls the buzzer driver module 226 to start, which in turn controls the buzzer 223 to sound an alarm to alert personnel. At the same time, the control module 225 also controls the LED driver module 227 to start, which in turn controls the LED 222 to light up a red light.
