Technical Field
[0001] This utility model relates to the field of residual current circuit breakers, specifically an integrated residual current circuit breaker. Background Technology
[0002] Residual current circuit breakers are crucial safety protection devices in low-voltage power distribution systems. They integrate the functions of connecting, disconnecting, overload protection, and residual current protection, and are widely used in homes, commercial and industrial settings. They can effectively prevent electric shock accidents and electrical fires caused by line leakage.
[0003] Currently, the open / closed status of residual current circuit breakers on the market is usually indicated only by the position of a mechanical handle. When the circuit breaker trips automatically due to line overload, short circuit, or leakage, the handle will switch to the open position. In dimly lit distribution boxes or when the circuit breaker trips due to a fault without the user's active operation, it is difficult to detect the change in the handle position in a timely and intuitive manner. Users may not realize that the trip has caused a power outage, making it difficult to troubleshoot and repair electrical faults in a timely manner. Therefore, an integrated residual current circuit breaker is proposed. Utility Model Content
[0004] The purpose of this invention is to provide an integrated residual current circuit breaker to solve the problems mentioned in the background art.

The conductive component is electrically connected to the indicator light, the indicator light is electrically connected to the battery, the battery is electrically connected to the buzzer, and the buzzer is electrically connected to the conductive component.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] An integrated residual current circuit breaker, such as Figures 1-4 As shown, the circuit breaker includes a circuit breaker body 1. The front of the circuit breaker body 1 is provided with a handle 2 for driving the opening and closing of the circuit breaker. The handle 2 is an existing structure. A side frame 3 is fixed to one side of the circuit breaker body 1. A cavity 4 is provided inside the side frame 3. An indicator light 10, a buzzer 14 and a power connection component are provided inside the cavity 4. The indicator light 10 and the buzzer 14 are relatively small. When they are powered, they will produce light and sound indications respectively. The indicator light 10, the buzzer 14 and the power connection component are electrically connected. A turntable 5 is rotatably installed on one side of the circuit breaker body 1. One side of the turntable 5 is inserted into the handle 2, and the other side is pressed into the power connection component to control the power connection component's energization status.
[0023] By installing indicator light 10 and buzzer 14 inside the side frame 3, when the circuit breaker is in the open state, the handle 2 is rotated to automatically trigger the power connection component through the turntable 5, causing the buzzer 14 to sound and the indicator light 10 to light up. This proactive and eye-catching prompting method can be easily noticed even in low light conditions or when the user does not operate it actively, so that the user can discover the power outage at the first time and troubleshoot the cause of faults such as leakage and overload in a timely manner, which greatly improves the safety of electricity use.
[0024] The power connection assembly includes a conductive component and a battery 15. The conductive component is electrically connected to the indicator light 10, the indicator light 10 is electrically connected to the battery 15, the battery 15 is electrically connected to the buzzer 14, and the buzzer 14 is electrically connected to the conductive component. The front end of the side frame 3 has a hole 9 and a mesh 23, and the indicator light 10 is installed in the hole 9.
[0025] When the conductive component is squeezed by one end of the turntable 5, the internal connection of the conductive component will be made, thereby enabling the battery 15 to power the indicator light 10 and the buzzer 14. The indicator light 10 is exposed through the hole 9 to facilitate light leakage, and the mesh 23 facilitates the sound of the buzzer 14 to be transmitted to the outside of the side frame 3.
[0026] The conductive component includes a first conductive block 11 and a second conductive block 12. A conductive spring 13 is fixedly attached to one side of the second conductive block 12. The end of the conductive spring 13 contacts and engages with the first conductive block 11. The first conductive block 11 is electrically connected to the indicator light 10, and the buzzer 14 is electrically connected to the second conductive block 12.
[0027] Conductive block 11, conductive block 2 12, buzzer 14 and battery 15 are all installed on the side wall of circuit breaker body 1 and located in cavity 4. Half of the turntable 5 is located in cavity 4. When one end of the turntable 5 presses the conductive spring 13, one end of the conductive spring 13 contacts the conductive block 11. The conductive spring 13 connects conductive block 11 and conductive block 2 12, energizing the conductive block 11 and conductive block 2 12. Therefore, the conductive block 11, conductive block 2 12, indicator light 10, buzzer 14 and battery 15 are energized, and the indicator light 10 and buzzer 14 operate.
[0028] A fixing rod 6 is fixedly connected to one side of the turntable 5. A connecting rod 7 is fixedly connected to the end of the fixing rod 6. The connecting rod 7 is inserted into the handle 2. A fixing rod 8 is fixedly connected to the other side of the turntable 5. The end of the fixing rod 8 is pressed into the conductive spring 13.
[0029] When the integrated residual current circuit breaker trips, the handle 2 rotates, and the handle 2 drives the fixed rod 6 to rotate via the connecting rod 7. The turntable 5 rotates, causing the fixed rod 8 to press against the conductive spring 13, thus energizing the conductive block 11 and the conductive block 12. The indicator light 10 and the buzzer 14 then operate. When the integrated residual current circuit breaker closes, the handle 2 rotates, and the handle 2 drives the fixed rod 6 to rotate via the connecting rod 7. The turntable 5 then rotates, causing the fixed rod 8 to disengage from the conductive spring 13. The conductive spring 13 returns to its original shape, thus de-energizing the conductive block 11 and the conductive block 12. The indicator light 10 and the buzzer 14 then stop operating.
[0030] The circuit breaker body 1 has a mounting groove 16 on the back, and a sliding groove is provided at the lower end of the mounting groove 16. A locking plate 17 is installed in the sliding groove, and a slot 18 is provided at the lower end of the locking plate 17.
[0031] The mounting slot 16 and the locking plate 17 work together to mount the back of the circuit breaker body 1 onto the bracket (the horizontal bracket in the existing circuit breaker installation method). The sliding locking plate 17 facilitates the installation and removal of the circuit breaker body 1.
[0032] The circuit breaker body 1 has a slot 22 inside, and the side wall of the locking plate 17 has a groove 19. A spring 20 is fixed inside the groove 19, and a locking block 21 is fixed to the end of the spring 20. The locking block 21 slides in the groove 19, and the end of the locking block 21 engages with the slot 22.
[0033] When the mounting groove 16 on the back of the circuit breaker body 1 aligns with the bracket and locks the groove 18, the locking plate 17 slides upward, causing the locking block 21 to be pressed until it enters the slot 22. The spring 20 presses the locking block 21, causing the locking block 21 to engage with the circuit breaker body 1, and the locking plate 17 is locked in place. Similarly, pulling the locking plate 17 downward makes it easy to disassemble the circuit breaker body 1.
[0034] The working principle of the integrated residual current circuit breaker provided by this utility model is as follows:
[0035] When the integrated residual current circuit breaker trips, the handle 2 rotates, which in turn drives the fixed rod 6 to rotate via the connecting rod 7. The turntable 5 rotates, causing the fixed rod 8 to press against the conductive spring 13, energizing the conductive block 11 and the conductive block 12. The indicator light 10 and the buzzer 14 then activate. When the integrated residual current circuit breaker closes, the handle 2 rotates, which in turn drives the fixed rod 6 to rotate via the connecting rod 7. The turntable 5 then rotates, causing the fixed rod 8 to disengage from the conductive spring 13. The conductive spring 13 returns to its original shape, de-energizing the conductive block 11 and the conductive block 12. The indicator light 10 and the buzzer 14 then deactivate. This proactive and conspicuous warning method ensures that the circuit breaker is easily detected even in low light conditions or when the user does not actively operate it. This allows users to detect power outages immediately and promptly troubleshoot faults such as leakage and overload, greatly improving electrical safety.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
