Embodiment Construction

[0034] Such as figure 1As shown, it is the electric operating mechanism with hidden protective baffle of the present invention, and the parts and components located in the housing 2 cannot be seen from this direction, and in figure 2 , 3 It is different in the middle, without installing the protective baffle 4, you can see the internal parts, including the handle structure 5 and the rotating shaft 6, as well as the shell 2 and the cover plate 3, almost all the parts are included in the shell In the body, it is covered by the cover plate 3. The handle structure 5 includes a handle 501, a rotating disk 503 and a coupling part 502. The rotating disk 503 has a shaft hole 5031 for installing the rotating shaft 6. Correspondingly, a shaft is also provided inside the support seat. Hole 801, axle hole 5031,801 are used for installing rotating shaft 6, as image 3 As shown, the handle 501 passes through the installation window 301 of the cover plate 3 and is sequentially connected w...

Abstract

The invention discloses an electric operating mechanism with a hidden protective baffle and the protective baffle. The electric operating mechanism comprises a handle structure and a rotary shaft, and further comprises a shell and a cover board, wherein the handle structure comprises a handle, a rotary disc and a connecting part; the rotary disc is provided with a shaft hole used for installation of the rotary shaft; the handle penetrates through an installation window of the cover board and is sequentially connected with the connecting part and the rotary disc inside the shell so as to form an integrated structure; the axis of the handle and the axis of the rotary shaft do not coincide; the protective baffle is arranged between the shell and the cover board; the protective baffle is provided with a notch matched with the handle structure so that the rotary disc can freely rotate; the upper end of the notch of the protective baffle is provided with a bridging part which is equivalent to the installation window in shape; when viewed from the side face, part structures inside the electric operating mechanism can not be seen, the electric operating mechanism is more attractive and is not prone to being polluted by dust, foreign materials can be prevented from falling into the electric operating mechanism, and the short-circuit phenomenon of an internal circuit caused by dust is avoided.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to a protective baffle and an electric operating mechanism using the protective baffle. Background technique [0002] Miniature circuit breaker, referred to as MCB, is the most widely used terminal protection device in electrical terminal power distribution devices. It is used for single-phase and three-phase short-circuit, overload, and overvoltage protection below 125A, including single-pole 1P, Two-pole 2P, three-pole 3P, four-pole 4P, etc. The electric operating mechanism of the circuit breaker is an accessory used for long-distance automatic opening and closing of the circuit breaker. The electric operating mechanism has two types: a motor operating mechanism and an electromagnet operating mechanism. The motor operating mechanism is used in the frame of the molded case circuit breaker. The closing and opening are achieved by the position of the cam inside the elect...
