The following is a detailed elaboration.

[0039] As Figures 1 to 6 shown, a signal device for a circuit breaker operating mechanism that can improve insulation performance includes

[0040] a frame 1, a lever 4 is arranged in the frame 1, the lever 4 makes elastic movement in the frame 1, and a poking rod 41 is arranged on the lever 4;

[0041] an insulated housing 2, which is fixed on the frame 1, a microswitch 3 is arranged in the insulated housing 2, and the button 31 of the microswitch 3 extends out of the insulated housing 2 and is adapted to cooperate with the poking rod 41.

[0042] The frame 1 of the circuit breaker includes a pair of side plates 11 and a top plate 12, and both sides of the top plate 12 are respectively connected to the two side plates 11.

[0043] In this embodiment, the working logic of the lever 4 in the circuit breaker refers to the prior patent, namely CN205194632U - Closing Ready Signal Device for Universal Circuit Breaker Operating Mechanism.

[0044] Openings are provided on both the front and rear sides of the insulating housing 2. The front opening is for the button 31 of the microswitch 3 to protrude, and the rear opening is for the power cord of the microswitch 3 to pass through.

[0045] Specifically, as an alternative implementation in this embodiment, as Figures 3 to 6 shown, the insulating housing 2 includes

[0046] The inner half shell 21, one side of which abuts against the side plate 11 of the frame 1 and is fixedly connected to the side plate 11 of the frame 1, and the other side forms an inner half cavity;

[0047] The outer half shell 22, an outer half cavity is formed on the outer half shell 22, a snap connection is formed between the outer half shell 22 and the inner half shell 21, and an insulating inner cavity for installing the microswitch 3 is formed between the inner half cavity and the outer half cavity.

[0048] Both the inner half shell 21 and the outer half shell 22 are made of insulating materials.

[0049] Specifically, as an alternative implementation in this embodiment, as Figures 3 to 6 shown, at least one connection hole 21-1 is opened on the inner half shell 21, and the connecting screw passes through the connection hole 21-1 and then connects with the side plate 11 of the frame 1 to fix the inner half shell 21 on the frame 1.

[0050] Specifically, as an alternative implementation in this embodiment, as Figures 3 to 6 shown, a connection pin 21-2 is provided at the upper end of the inner half shell 21, a connection hole 21-1 is opened on the top plate 12 of the frame 1, and the connection pin 21-2 is inserted into the connection hole 21-1.

[0051] The connection pin 21-2 can also be provided on the outer half shell 22.

[0052] The connection between the insulating housing 2 and the circuit breaker frame 1 depends on both the connecting screw passing through the connection hole 21-1 and connecting and fixing with the side plate 11, and also on the connection pin 21-2 being snap-connected with the top plate 12.

[0053] Specifically, as an alternative implementation in this embodiment, as Figure 5 and Figure 6 shown, positioning pins 23 are provided in both the inner half cavity and the outer half cavity, positioning holes are opened on the microswitch 3, and the microswitch 3 is installed in the insulating housing 2 through the positioning pins 23.

[0054] During the assembly process of the insulating housing 2, the inner half shell 21 and the outer half shell 22 are snap-connected, and the micro switch 3 can be just fixed in the chamber.

[0055] The positioning pin 23 can also be only arranged in the inner half chamber or the outer half chamber, as long as the micro switch 3 can be fixed.

[0056] Specifically, as an optional implementation manner in this embodiment, as Figure 4 shown, a support convex ring 21-3 is arranged on the inner side surface of the inner half shell 21, and the inner half chamber abuts against the side plate 11 of the frame 1 through the support convex ring 21-3.

[0057] The inner half shell 21 abuts against the side plate 11 through the support convex ring 21-3, reducing the contact area with the side plate 11, thereby reducing the risk of creepage and improving the overall insulation of the housing.

[0058] Specifically, as an optional implementation manner in this embodiment, as Figure 5 shown, a plurality of guide grooves 21-4 are arranged on the outer wall of the inner half shell 21, and clamping blocks are arranged in the guide grooves 21-4;

[0059] A plurality of guide blocks 22-1 are arranged on the outer half shell 22, and a plurality of card slots are opened on the guide blocks 22-1;

When the clamping blocks are matched with the card slots, the outer half shell 22 and the inner half shell 21 are snap-connected.

[0061] In this embodiment, the number of both the guide grooves 21-4 and the guide blocks 22-1 is three.

[0062] When the circuit breaker is operating, when it is in a state of satisfying energy storage, and the mechanism is tripped and there is power under under-voltage, the toggle lever 41 can press the button 31 of the micro switch 3 under the action of the contraction spring, triggering the micro switch 3 to make the device send out a signal indicating that closing is ready.

[0063] The micro switch 3 is installed on the side plate 11 and the top plate 12 of the frame 1 through the insulating housing 2, improving the insulation performance of the micro switch 3. Secondly, the installation structure between the insulating housing 2 and the frame 1 is stable and reliable, convenient for disassembly and assembly, and the micro switch 3 can also remain stable inside the insulating housing 2.
