Description

Technical Field

[0001] This invention belongs to the field of circuit breaker technology, specifically relating to a circuit breaker operation device for indicating whether the circuit is open or closed. Background Technology

[0002] Currently, the buttons on universal circuit breaker operating devices are located inside a cover. These buttons can move back and forth within a groove in the cover and are reset by a spring. The circuit breaker's operating mechanism has a guide lever, which is fixed to the mechanism and can move back and forth within a certain range. One end of the guide lever contacts the button on the cover, while the other end is linked to the operating mechanism's opening / closing shaft via structural components. When an operation is required, pressing the button activates the guide lever and related structural components, causing the operating mechanism to perform the corresponding opening or closing action. However, with this traditional circuit breaker operating device, pressing the button closes the circuit breaker, and the button springs back to its original position after the operating force is removed. Pressing the button again opens the circuit breaker. When the circuit breaker is installed in a cabinet and closed, pulling it out may not disconnect it, causing an electric arc at the circuit breaker's terminals and endangering nearby equipment. Therefore, it is essential to display the circuit breaker's opening / closing status to prevent accidental closing accidents.

[0003] Chinese patent ZL201720171498.7 discloses a circuit breaker operating mechanism with opening and closing indication function. It includes a button and an indicator. The button has a cavity, and the indicator is housed within the cavity. The indicator can swing within the cavity. The button has an observation window, which displays different areas during the swing of the indicator. The operating button has two different states when the circuit breaker contacts are closed and open, and the indicator simultaneously indicates the closing / opening status. However, during the movement of the button, a boss on the outer casing pushes a tooth on the indicator, causing the indicator to rotate within the button. The boss on the outer casing is equivalent to a tooth of a spur gear, utilizing a gear drive principle. Gear structures have high clearance requirements. When the clearance between the outer casing and the indicator is large, the rotation angle error of the indicator is large, resulting in inaccurate color of the exposed button portion. Sometimes, half red and half green can be seen through the observation window, failing to accurately indicate the closing / opening status of the circuit breaker. On the other hand, when the product is assembled with the lid closed, the two teeth on the indicator cannot be accurately aligned and engaged with the boss on the outer shell in the free state. After assembly, the boss on the outer shell is not between the two teeth on the indicator, causing assembly errors and reducing production efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the technical shortcomings of existing circuit breaker operating devices that rely on gear transmission, leading to inaccurate indications and assembly difficulties. This invention provides a circuit breaker operating device with a corresponding indicator. During button operation, a protrusion on the housing presses down on a corresponding part of the indicator inside the button, enabling the indicator to function. When the circuit breaker is in the open or closed position, the protrusion on the housing presses down on a part of the indicator that is far from the indicator's rotation center. A small gap between the indicator and the housing has minimal impact on the indicator's rotation angle, allowing the indicator to accurately indicate the circuit breaker's open / closed status. Furthermore, during assembly with the cover closed, regardless of the indicator's angle in its free state, the protrusion on the housing can press the indicator into the correct position, improving production efficiency.

[0005] Technical solution

[0006] To achieve the above-mentioned technical objectives, this invention designs a circuit breaker operating device for indicating opening and closing, comprising a button and an indicator. The button has a cavity, and the indicator is installed within the cavity and can rotate within it. The button has an observation window, which displays different areas during the rotation of the indicator. Its distinguishing feature is:

[0007] The indicator includes a rotating disk with a mounting shaft extending from its side. The mounting shaft is installed in a mounting hole on the inner wall of the cavity and can rotate. A linkage wing is provided on the outer edge of the rotating disk. A display handle extends from the outer edge of the rotating disk. The display surface of the display handle corresponds to the observation window. The display surface can display different areas in the observation window during the rotation of the indicator.

[0008] The button is installed in the button slot of the circuit breaker housing. A boss is provided on the inner wall of the housing corresponding to the linkage wing platform. The button is connected to the handle through a U-shaped connecting rod.

[0009] Furthermore, the linkage wing platform includes a left wing platform and a right wing platform, and the protrusion can respectively move and press the left wing platform or the right wing platform during the rotation of the indicator.

[0010] Furthermore, the left and right wing platforms include an arc-shaped actuating part and a pressing straight part.

[0011] Furthermore, the observation window is located on the left end face of the button.

[0012] Furthermore, one end of the U-shaped connecting rod is installed in the oblong hole on the button, and the other end is connected to the handle.

[0013] Preferably, the display handle is a flexible display handle.

[0014] Preferably, the linkage wing platform has elasticity.

[0015] Beneficial effects

[0016] This invention provides a circuit breaker operating device with an opening / closing indicator. During button operation, a protrusion on the housing presses against a corresponding part of the indicator inside the button, enabling the indicator to function as an indicator. When the circuit breaker is in the open or closed position, the part of the protrusion pressing against the indicator is far from the rotation center of the indicator. A small gap between the indicator and the housing has minimal impact on the rotation angle of the indicator, allowing it to accurately indicate the circuit breaker's opening / closing status. Furthermore, the clearance requirements during assembly are lower. Regardless of the angle, the protrusion on the housing can press the indicator into the correct position when it is in its free state, improving production efficiency. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Example

[0025] As attached Figure 1 As shown, a circuit breaker operating device includes a circuit breaker opening / closing indicator, comprising a button 1 and an indicator 2. The button 1 has a cavity 101, and the indicator 2 is mounted within the cavity 101 and can rotate within it. The button 1 has an observation window 102 located on its left end face. During rotation, the indicator 2 displays different areas within the observation window 102.

[0026] As attached Figure 3 As shown, the indicator 2 includes a rotating disk 201, with a mounting shaft 202 extending from the side of the rotating disk 201. The mounting shaft 202 is installed in a mounting hole 101a on the inner wall of the cavity 101 and can rotate. A linkage wing platform 204 is provided on the outer edge of the rotating disk 201. A display handle 205 extends from the outer edge of the rotating disk 201. The display surface 203 of the display handle 205 corresponds to the observation window 102. The display surface 203 includes a region 203a and a region 203b. During the rotation of the indicator 2, the display surface 203 can display different regions in the observation window 102, where region 203a is green and region 203b is red.

[0027] As attached Figure 6 As shown, the button 1 is installed in the button slot 301 of the circuit breaker housing 3, as per the attached diagram. Figure 2 As shown, a boss 4 is provided on the inner wall of the outer casing 3 at a position corresponding to the linkage wing platform 204. The button 1 is connected to the handle 6 via a U-shaped connecting rod 5. One end of the U-shaped connecting rod 5 is installed in the oblong hole 103 on the button 1, and the other end is connected to the handle 6.

[0028] In detail, the linkage wing platform 204 includes a left wing platform 204a and a right wing platform 204b. The protrusion 4 can respectively move and press the left wing platform 204a or the right wing platform 204b during the rotation of the indicator 2. The left wing platform 204a and the right wing platform 204b include an arc-shaped moving part and a pressing straight part.

[0029] As attached Figure 4 As shown, in the open state of the circuit breaker, the boss 4 on the housing 3 presses against the right wing 204b of the indicator 2. The lower part of the left display surface 203a of the indicator 2 is close to the lower wall of the inner cavity 101 of the button 1. The display surface 203a faces the observation window 102, and the indicator 2 appears green when viewed through the observation window 102. Pushing the button 1 to the right rotates the circuit breaker mechanism, causing the circuit breaker to close. After releasing the button 1, the button 1 remains in the closed position. During the pressing process of the button 1, the boss 4 on the housing 3 changes from pressing against the right wing 204b of the indicator 2 to pressing against the left wing 204a of the indicator 2. The indicator 2 rotates clockwise, and the color changes from green to red when viewed through the observation window 102, as the indicator 2 changes from display area 203a to display area 203b.

[0030] like Figure 5As shown, in the closed state of the circuit breaker, the boss 4 on the housing 3 presses against the left wing 204a of the indicator 2. The upper part of the left display surface 203b of the indicator 2 is close to the upper wall of the inner cavity 101 of the button 1. The display surface 203b faces the observation window 102. When the indicator 2 is viewed through the observation window 102, its color is red. Pulling the button 1 to the left causes the circuit breaker mechanism to rotate, thus opening the circuit breaker. After releasing the button 1, it remains in the open position. During the pulling of the button 1, the boss 4 on the housing 3 changes from pressing against the left wing 204a of the indicator 2 to pressing against the right wing 204b of the indicator 2. The indicator 2 rotates counterclockwise. When viewed through the observation window 102, the indicator 2 changes from display area 203b to display area 203a, and its color changes from red to green.

[0031] Example 2

[0032] In another embodiment of the present invention, the display handle 205 connecting the observation surface of the indicator 2 and the rotating disk 201 is an elastic component. When the left observation surface of the indicator 2 contacts the side wall of the button 1, the boss 4 on the outer casing 3 presses against the left wing 204a and right wing 204b of the indicator 2, causing the display handle 205 between the observation surface of the indicator 2 and the rotating shaft to undergo elastic deformation. Other components of the indicating device in this embodiment are the same as in Embodiment 1.

[0033] Example 3

[0034] In another embodiment of the present invention, the left wing platform 204a and the right wing platform 204b of the linkage wing platform 204 of the indicator 2 are elastic components. When the left observation surface of the indicator 2 contacts the side wall of the button 1, the protrusion 4 on the outer shell 3 presses against the left wing platform 204a and the right wing platform 204b of the indicator 2, causing the left wing platform 204a and the right wing platform 204b of the indicator 2 to undergo elastic deformation. The other working methods of the indicating device in this embodiment are the same as in Embodiment 1.
