Embodiment 1）

[0040] The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0041] See figure 1 As shown, this embodiment is an automatic opening and closing miniature circuit breaker, including a circuit breaker body 2 and an automatic opening and closing drive mechanism 1; in this embodiment, the circuit breaker body includes two circuit breakers 20 (also called miniature circuit breakers breaker or miniature circuit breaker). In practice, according to specific requirements, the number of miniature circuit breakers combined into the circuit breaker body can be arbitrarily selected from one to four.

[0042] See Figure 1 to Figure 7 As shown, each circuit breaker includes a plastic case 21, an opening and closing handle 22, a moving contact, a static contact, an operating mechanism 25, an incoming power terminal 26, an outgoing power terminal 27, and an arc extinguishing mechanism 28; each opening and closing A spindle hole 221 is prov...

Abstract

The invention discloses an automatic opening and closing small circuit breaker, which comprises a circuit breaker body and an automatic opening and closing driving mechanism, wherein the circuit breaker body comprises one to four circuit breakers; each circuit breaker comprises a plastic shell, an opening and closing handle, an operation mechanism, an electricity input wiring terminal, an electricity output wiring terminal and an arc extinguishing mechanism; the automatic opening and closing driving mechanism comprises a shell, a circuit board, an electricity input spring and an electricity inspection spring; the electricity input spring is electrically connected with the circuit board and the electricity input wiring terminal of any circuit breaker; and each electricity inspection spring is electrically connected with the circuit board and the electricity output wiring terminal of any circuit breaker. During a process during which the automatic opening and closing driving mechanism is assembled with the small circuit breaker, iron welding is not needed, electrical connection is carried out easily, and the assembly process and the disassembly process are quick and convenient.

Description

technical field [0001] The technical field of the miniature circuit breaker of the present invention, in particular relates to an automatic opening and closing miniature circuit breaker. Background technique [0002] According to the needs of my country's power supply network intelligence, the State Grid Corporation of China requires the power supply network intelligence. Therefore, it is necessary for the terminal actuator of the power supply network - the miniature circuit breaker (or miniature circuit breaker) to execute the upper-end signal and have the functions of tripping and closing. Therefore, the current development trend of miniature circuit breakers is that in addition to the traditional manual opening and closing and overcurrent and overload automatic tripping functions, it also needs to have an electric opening and closing function (commonly known as automatic opening and closing function) to achieve remote control; especially It is a combination of smart mete...
