[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a signal device for ready-to-close, including an operating mechanism 1 and a micro switch 2. The operating mechanism 1 includes a side plate 11 and an aircraft lever 12. The aircraft lever 12 is arranged on the inner side of the side plate 11. The aircraft lever 12 is limited on the side plate 11 and can move along the first direction a. The aircraft lever 12 has a first position when the operating mechanism 1 is in an energy storage and non-closed state, and a second position when the operating mechanism 1 is in an energy storage and closed state. The micro switch 2 is arranged on the inner side of the side plate 11, and a trigger 13 is provided in the middle of the aircraft lever 12. The trigger 13 is used to trigger the micro switch 2 when the aircraft lever 12 is in the first position, or not trigger the micro switch 2 when the aircraft lever 12 is in the second position.

[0033] The closing ready signal device provided in this embodiment has a micro switch 2 arranged on the side plate 11. When the operating mechanism 1 is in the energy storage and non-closing state, the aircraft lever 12 is in the first position, and the trigger 13 on the aircraft lever 12 triggers the micro switch 2 to form a closing ready signal, and the universal circuit breaker is in a closing state. When the operating mechanism 1 is in the energy storage and closing state, the aircraft lever 12 is in the second position, and the trigger 13 does not trigger the micro switch 2 to form a non-closing signal, and the universal circuit breaker is in a non-closing state, which replaces the prior art that adds a closing ready signal. The scheme of the ready indicator is adopted, and the trigger member 13 is arranged on the aircraft lever 12, and the trigger member 13 and the aircraft lever 12 act synchronously, thereby reducing the indication failure rate; in addition, the micro switch 2 and the aircraft lever 12 are arranged on the same side of the side plate 11, and the trigger member 13 is arranged in the middle of the aircraft lever 12, which can make full use of the space between the aircraft lever 12 and the side plate 11, thereby improving the compactness of the overall structure of the universal circuit breaker, and when the aircraft lever 12 moves, the trigger member 13 will not interfere with other components, and can stably trigger the micro switch 2, or not trigger the micro switch 2, thereby reducing the indication failure rate.

[0034] In some embodiments, in combination Figure 2 and Figure 3 As shown, a mounting plate 14 is provided on the inner side of the side plate 11, one end of the mounting plate 14 is connected to the side plate 11, the other end of the mounting plate 14 is bent and spaced from the side plate 11, and the micro switch 2 is fixedly provided on the other end of the mounting plate 14. The mounting plate 14 is provided to facilitate the installation of the micro switch 2, so that the micro switch 2 is spaced from the side plate 11 to avoid affecting the triggering of the micro switch 2 and improve the stability of the triggering of the micro switch 2. Further optionally, a threaded hole is provided on the other end of the mounting plate 14, and the micro switch 2 is fixed to the mounting plate 14 by a bolt.

[0035] In some embodiments, the trigger member 13 includes a trigger rod, one end of which is connected to the middle of the aircraft lever 12, and the other end of the trigger rod extends toward one side of the micro switch 2 and is used to trigger the micro switch 2. The structure is simple, and the trigger rod can directly trigger the micro switch 2, thereby improving the stability of triggering the micro switch 2 to form a closing signal.

[0036] The trigger member 13 can be arranged at the middle position of the aircraft lever 12. Along the first direction a, the trigger member 13 can also be arranged at other positions close to the middle position of the aircraft lever 12. The micro switch 2 is arranged corresponding to the trigger member 13. There is no specific limitation on the positions where the trigger member 13 and the micro switch 2 are arranged, as long as the installation and stable triggering requirements are met.

[0037] In this embodiment, continue to refer to Figure 1 and Figure 2As shown, the operating mechanism 1 also includes a closing half shaft 15, on which a first protrusion 151 is provided, and a second protrusion 121 is provided at the first end of the aircraft lever 12. When the aircraft lever 12 is in the first position, the operating mechanism 1 is in a closing state, and the second protrusion 121 is placed above the first protrusion 151 in the second direction b. When the aircraft lever 12 is hit by an external force, the second protrusion 121 can exert a force on the first protrusion 151, so that the closing half shaft 15 rotates and the operating mechanism 1 closes. When the aircraft lever 12 is in the second position, the operating mechanism 1 is in a non-closing state, and the second protrusion 121 and the first protrusion 151 are staggered in the first direction a. Even if the aircraft lever 12 is hit by an external force, the second protrusion 121 will not act on the first protrusion 151.

[0038] A trigger block 18 is provided at the first end of the aircraft lever 12. The trigger block 18 is used to contact the closing electromagnet of the universal circuit breaker. The action of the closing electromagnet can exert force on the trigger block 18, thereby causing the aircraft lever 12 to move. The second protrusion 121 on the aircraft lever 12 contacts the first protrusion 151 to close the operating mechanism 1.

[0039] A lever 19 is provided at the second end of the aircraft lever 12, and a limiting hole 111 is provided on the side plate 11. The limiting hole 111 extends along the first direction a. The lever 19 passes through the limiting hole 111, and the limiting hole 111 limits the range of movement of the aircraft lever 12 in the first direction a.

[0040] like Figure 4 and Figure 5 As shown, the operating mechanism 1 also includes a switch-on / off indicator 16, which is rotatably installed and used to display the state of the switch-on or switch-on. When the operating mechanism 1 is in the energy storage and non-closing state, the switch-on / off indicator 16 puts the aircraft lever 12 in the first position. When the aircraft lever 12 is in the first position, the second protrusion 121 is placed above the first protrusion 151 in the second direction b, the trigger 13 triggers the micro switch 2, and the ready-to-close signal is formed. The second protrusion 121 can trigger the first protrusion 151 to close the operating mechanism 1. When the operating mechanism 1 is in the closing state after energy storage, the switch-on / off indicator 16 puts the aircraft lever 12 in the second position, the second protrusion 121 and the first protrusion 151 are staggered in the first direction a, the trigger 13 no longer triggers the micro switch 2, and a signal that the switch cannot be closed is formed, and the second protrusion 121 cannot trigger the first protrusion 151. After the operating mechanism 1 is closed, the switch-on / off indicator 16 is actuated to display the closed state, and the aircraft lever 12 is moved from the first position to the second position, and the aircraft lever 12 is kept in the second position. When the operating mechanism 1 is energy-storing and not closed, the switch-on / off indicator 16 does not limit the aircraft lever 12, and the aircraft lever 12 is moved from the second position to the first position.

[0041] Further optionally, a limit rod 161 is provided on the opening and closing indicator 16, and a limit surface 122 is provided on the aircraft lever 12, and the limit rod 161 contacts the limit surface 122. When the opening and closing indicator 16 rotates to switch from displaying the opening to displaying the closing, the limit rod 161 pushes the limit surface 122, so that the aircraft lever 12 moves from the first position to the second position. When the opening and closing indicator 16 rotates to switch from displaying the closing to displaying the opening, the limit rod 161 does not apply force to the limit surface 122, and the aircraft lever 12 switches from the second position to the first position.

[0042] The operating mechanism 1 further includes an elastic member 17, one end of which is connected to the side plate 11, and the other end of which is connected to the middle of the aircraft lever 12. The elastic member 17 is configured to move the aircraft lever 12 from the second position to the first position. That is, when the opening and closing indicator 16 rotates from displaying the opening to displaying the closing, the limit rod 161 pushes the limit surface 122, so that the aircraft lever 12 moves from the first position to the second position. In this case, the elastic member 17 stores energy. In this embodiment, the elastic member 17 is stretched and stores energy in this state. When the opening and closing indicator 16 rotates from displaying the closing to displaying the opening, the limit rod 161 does not apply force to the limit surface 122, and the elastic member 17 releases the stored energy to reset, thereby driving the aircraft lever 12 to move from the second position to the first position. When the aircraft lever 12 moves between the first position and the second position, the limit rod 161 is always in contact with the limit surface 122.

[0043] The operating mechanism 1 provided in the present application also includes other structures. Since the other structures are prior arts, they will not be described in detail here.

[0044] This embodiment also provides a universal circuit breaker, which includes the above-mentioned closing ready signal device.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
