[0002] The intelligent molded case circuit breaker is a circuit breaker with integrated intelligent control functions, which can monitor parameters such as current, voltage, temperature, and realize remote control and fault diagnosis. It can improve the safety and reliability of electrical equipment, and can also realize remote monitoring and management. The intelligent molded case circuit breaker in the prior art usually uses the elasticity of the spring to cooperate with the joystick to control the closing of the intelligent molded case circuit breaker. However, when the intelligent molded case circuit breaker trips in a short circuit, the elasticity of the spring will drive the joystick to collide with the intelligent molded case circuit breaker. Repeated collisions may cause the joystick to break, which will cause the staff to be unable to control the use of the intelligent molded case circuit breaker. At the same time, a large amount of heat energy will accumulate inside the intelligent molded case circuit breaker when it is short-circuited, which may cause the intelligent molded case circuit breaker to overheat and reduce its service life.

[0023] A card slot 11 is provided on the left side of the protective shell 1, and the card slot 11 is a quadrilateral notch. The card slot 11 is conveniently fixed to the wall with a matching fixing block or mounting plate, and the square slot 2 is provided on the front of the protective shell 1. Ventilation slots 3 are inserted at both ends of the protective shell 1. The ventilation slots 3 can facilitate the heat dissipation of the intelligent molded case circuit breaker. A protective mechanism 4 is inserted on the front of the protective shell 1. The protective mechanism 4 can close the ventilation slot 3 and reduce the impact of the joystick.

[0024] See also Figure 3-4The protective mechanism 4 includes a T-shaped hollow column 41, which can be connected to an I-shaped plate 42. Both ends of the top of the T-shaped hollow column 41 are provided with transverse grooves 412, and the transverse grooves 412 are slidably connected to the inclined rod 44. The transverse grooves 412 facilitate the transmission of the inclined rod 44. The T-shaped hollow column 41 is connected to the front side of the protective shell 1, and the interior of the T-shaped hollow column 41 is slidably connected to the I-shaped plate 42, which can reduce the impact of the joystick.

[0025] A soft board 421 is fixedly connected to the top of the I-shaped plate 42, and the soft board 421 is a square plastic pad. The soft board 421 can prevent the I-shaped plate 42 from causing wear to the operating lever of the intelligent molded case circuit breaker. Vertical grooves 411 are provided at both ends of the outside of the T-shaped hollow column 41, and the vertical grooves 411 are slidably connected to the oblique rod 44. The vertical grooves 411 facilitate the transmission of the oblique rod 44. The back of the T-shaped hollow column 41 is evenly spaced with a first elastic member 43.

[0026] The first elastic member 43 is connected to the inside of the T-shaped hollow column 41. The two ends of the back side of the I-shaped plate 42 are connected to inclined rods 44 through double-head hinges. The inclined rods 44 can transmit power to the slider 45. The back side of the inclined rod 44 is connected to the slider 45 through a hinge. The slider 45 can transmit power to the closing plate 47. The slider 45 is slidably arranged inside the T-shaped hollow column 41, and the ends of the two sliders 45 that are away from each other are fixedly connected to a cross arm 46.

[0027] The T-shaped hollow column 41 is connected to the protective shell 1 by bolts, and the cross arm 46 is connected through the ventilation slot 3.

When the intelligent molded case circuit breaker is short-circuited, the operating rod will be driven by the spring to trip, and then it will contact the soft board 421 before the soft board 421. The first elastic member 43 and the second elastic member 48 cooperate to cushion the impact force between the soft board 421 and the operating rod. At the same time, the soft board 421 is driven to drive the I-shaped plate 42 to move inside the T-shaped hollow column 41, and then drive the inclined rod 44 to transmit, driving the two sliders 45 to move away from each other, and then drive the closing plate 47 to move through the cross arm 46, so that the closing plate 47 contacts and closes the ventilation slot 3, so that the ventilation slot 3 can discharge the heat energy generated by the short circuit of the intelligent molded case circuit breaker.

[0029] When the intelligent molded case circuit breaker is short-circuited, the added protection mechanism 4 reduces the impact force on the operating lever of the intelligent molded case circuit breaker to prevent the operating lever from colliding with the protective shell 1 through the elasticity of the spring and causing breakage. At the same time, when the intelligent molded case circuit breaker is short-circuited, the protection mechanism 4 automatically releases the closure of the ventilation slot 3, so that the ventilation slot 3 discharges the heat energy inside the intelligent molded case circuit breaker. At the same time, the ventilation slot 3 is closed by the protection mechanism 4 under normal conditions to prevent external dust from being adsorbed inside the intelligent molded case circuit breaker due to static electricity.
