Operation mechanism of circuit breaker

Abstract

The invention discloses an operation mechanism of a circuit breaker. The operation mechanism of the circuit breaker comprises a toothed turnplate, a transmission block, a transmission mechanism and a circuit board, the toothed turnplate is arranged between the transmission block and the circuit board, the toothed turnplate comprises an arc-shaped groove, a hollow round hole, an inductor and two protruding blocks, the arc-shaped groove is located between the two protruding blocks, the inductor is arranged at the upper ends of the protruding blocks of the toothed turnplate, the inductor and the protruding blocks are located on two sides of the toothed turnplate respectively, the transmission block is provided with an installation rod, a first boss and a second boss, the installation rod is located at the center of the transmission block, one end of the installation rod penetrates through the round hole and is movably matched with the round hole, the other end of the installation rod is fixedly matched with the transmission mechanism, the second boss is provided with a groove, and the circuit board is provided with sensors. The operation mechanism is integrally linked with the circuit breaker, the product mechanism is in a completely closed state, and meanwhile the height of a product is not increased; the toothed turnplate is adopted for driving the transmission mechanism of the transmission block, and the structure is simple; the sensors are adopted for detecting the running position of the operation mechanism, and the size of the operation mechanism is reduced.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to an operating mechanism of the circuit breaker. Background technique [0002] At present, the operating mechanism of the circuit breaker generally uses an external handle to drive the circuit breaker to operate, and the position of the handle is detected by the micro switch to obtain the closing and opening state of the circuit breaker, and the closing and opening operation of the circuit breaker is realized through a complex mechanism. This method has the following disadvantages: [0003] 1. When the handle of the operating mechanism drives the circuit breaker to link, because the handle has an operating arm, it is difficult to close the contacts of the multi-pole circuit breaker at the same time. [0004] 2. When the operating handle of the operating mechanism swings, a hole needs to be opened in the casing, so the operating mechanism cannot be completely enclosed in the casing, and does no...

Problems solved by technology

[0003] 1. When the handle of the operating mechanism drives the circuit breaker to link, because the handle has an operating arm, it is difficult to close the contacts of the multi-pole circuit breaker at the same time

[0004] 2. When the operating handle of the operating mechanism swings, a hole needs to be opened in the casing, so the operating mechanism cannot be completely enclosed in the casing, and it does not have the feature of preventing the entry of solid particles

[0005] 3. The micro switch is large in size, which is not conducive to the miniaturization of the operating mechanism
