[0031] To illustrate the technical solution described in this utility model, specific embodiments are described below, showing only the parts related to the embodiments of this utility model.

[0032] Example 1:

[0033] like Figure 1 As shown, this utility model provides a miniature circuit breaker installation device for an electricity meter, including a base 1, a mounting base 2, and a terminal cover 3 for fixing the circuit breaker 4. The base 1 is fixed to the bottom shell 5 of the electricity meter, and the mounting base 2 is fixed to the base 1. The mounting base 2 is used to assemble the circuit breaker 4. The terminal cover 3 is fixed to the bottom shell 5, and the terminal cover 3 is engaged with the base 1. The terminal cover 3 and the base 1 cooperate with each other to assemble the circuit breaker 4 between the terminal cover 3 and the base 1. Specifically, the mounting base 2 is connected to the electricity meter through the base 1, and one end of the circuit breaker 4 is fixed to the mounting base 2. The bottom of the terminal cover 3 matches the base 1. When the terminal cover 3 is fixedly connected to the bottom shell 5, the terminal cover 3 and the base 1 fixed on the bottom shell 5 cooperate to form a receiving cavity for accommodating the wiring terminals 6 of the electricity meter and the circuit breaker 4. At the same time, the other end of the circuit breaker 4 can pass through the terminal cover 3 and be exposed outside the terminal cover 3, so that the user can operate the circuit breaker 4 normally without opening the terminal cover 3. The circuit breaker 4 and the wires connecting the circuit breaker 4 to the terminal 6 of the electricity meter are integrated inside the electricity meter, which facilitates the installation of the electricity meter and makes it less likely for the wires between the circuit breaker 4 and the terminal 6 to be connected incorrectly. The cavity formed by the terminal cover 3 and the base 1 can protect the internal circuit breaker 4, so that the circuit breaker 4 does not need to be installed separately in the metering distribution box, which can prevent wire theft and ensure the safety of the electricity meter's operating environment.

[0034] This utility model installs a base 1 and a mounting base 2 for assembling a circuit breaker 4 on the bottom shell 5 of the electricity meter. The circuit breaker 4 is quickly snapped onto the mounting base 2. Through the mutual cooperation between the terminal cover 3 and the base 1, the circuit breaker 4 is mounted between the mounting base 2 and the terminal cover 3 of the base 1, thereby assembling the circuit breaker 4 onto the electricity meter.

[0035] As an optional implementation method, such as Figure 2 As shown, the mounting base 2 is provided with a slot 21 and a bevel 22. The slot 21 is located at the upper end of the mounting base 2 and matches the latch 41 at the bottom of the circuit breaker 4, allowing the latch 41 to engage within the slot 21. The bevel 22 is located on both sides of the bottom surface of the slot 21 and is used to cooperate with the latch 41. Specifically, the slot 21 and the latch 41 match, the slot 21 can be engaged within the latch, and the baffles on both sides of the slot 21 abut against the side wall at the upper end of the latch 41, allowing the upper end of the latch 41 to be clamped between the two baffles. The bevel 22 is inclinedly set on the bottom surface of the slot 21. When the slot 41 of the circuit breaker 4 is engaged in the slot 21, the limiting fixing member 42 (described below) at the opening of the slot 41 can engage with the bottom surface of the slot 21 and be in contact with the bevel 22 on the bottom surface of the slot 21. Through the cooperation between the bevel 22 and the limiting fixing member 42, the circuit breaker 4 is stably fixed on the mounting base 2.

[0036] As an optional implementation method, such as Figure 2 and Figure 3 As shown, the circuit breaker 4 includes a limiting fixing member 42, an operating switch 43, and terminals 44. The limiting fixing member 42 is disposed within the bayonet 41 and matches the upper end of the mounting base 2. The circuit breaker 4 is engaged with the mounting base 2 via the limiting fixing member 42. There are two terminals 44, which are respectively installed on both sides of the operating switch 43. The operating switch 43 is used to control the connection of the circuit. The limiting fixing member 42 includes a first limiting block 421 and a second limiting block 422. When the circuit breaker 4 is fixed on the base 1, the first limiting block 421 abuts against the bevel 22 on the first side of the bottom surface of the slot 21, and the second limiting block 422 abuts against the bevel 22 on the second side of the bottom surface of the slot 21. Specifically, the limiting and fixing component 42 is set at the opening of the bayonet 41, the first limiting block 421 is set on the first side of the opening of the bayonet 41, and the second limiting block 422 is set on the second side of the opening of the bayonet 41. Both the first limiting block 421 and the second limiting block 422 are matched with the bevel 22 on the mounting base 2. Through the cooperation of the first limiting block 421 and the second limiting block 422 with the bevel 22, the circuit breaker 4 is locked onto the upper end of the mounting base 2. The operating switch 43 is set on the manual operation surface at the upper end of the circuit breaker 4. By adjusting the operating switch 43 left and right, the circuit can be connected or disconnected. Wiring holes are provided on both sides of the circuit breaker 4. Each wiring hole corresponds to the terminal 44 on both sides of the operating switch 43, which facilitates the wires to extend into the circuit breaker 4 from the wiring hole and connect to the terminal 44.

[0037] As an optional implementation, both the first limiting block 421 and the second limiting block 422 are made of elastic material. Specifically, both the first limiting block 421 and the second limiting block 422 are made of elastic material with good elastic properties. When the circuit breaker 4 is engaged and connected to the mounting base 2, the first limiting block 421 and the second limiting block 422 can undergo elastic deformation under the force applied during installation, allowing the first limiting block 421 and the second limiting block 422 at the opening of the bayonet 41 to engage with the lower part of the slot 21. After the circuit breaker 4 is engaged and connected to the slot 21 of the mounting base 2, the first limiting block 421 and the second limiting block 422 on the circuit breaker 4 return to their elastic deformation, and both the first limiting block 421 and the second limiting block 422 abut against the bevel 22 at the bottom of the slot 21. The first limiting block 421 and the second limiting block 422 can both be made of silicone.

[0038] As an optional implementation method, such as Figure 4As shown, the base 1 includes a connecting part 11 and a wiring port 12. The connecting part 11 is located at the first end of the base 1 and matches the mounting groove 51 of the base shell 5. The first end of the base 1 matches the base shell 5, and the connecting part 11 engages with the mounting groove 51. The through-hole structure 111 on the connecting part 11 is fitted onto the mounting hole 52 of the base shell 5. There are two wiring ports 12, located on both sides of the mounting base 2. Specifically, the first end of the base 1 matches the base shell 5. The connecting part 11 at the first end of the base 1 can engage in the mounting groove 51 at the bottom of the base shell 5 and pass through one side of the mounting groove 51, so that the through-hole structure 111 on the connecting part 11 can fit onto the mounting hole 52 at the bottom of the base shell 5. The connection is made by screws, bolts, etc., to ensure that the base 1 is stably installed on the base shell 5. Since the first end of the base 1 matches the base shell 5, when the base 1 is installed on the base shell 5, the first end of the base 1 and the base shell 5 are tightly abutted, which facilitates the sealing of the structure. Two wiring ports 12 are conveniently located on both sides of the mounting base 2, allowing the wires connected to the circuit breaker 4 on the mounting base 2 to enter and exit through the wiring ports 12, ensuring that the installation of the circuit breaker 4 and the wires is convenient and secure.

[0039] As an optional implementation method, such as Figure 2 As shown, the terminal cover 3 is provided with a circuit breaker switch window 31, which corresponds to the mounting base 2 fixed on the base 1. The circuit breaker switch window 31 allows the manual operation surface of the circuit breaker 4 fixed on the mounting base 2 to extend out of the terminal cover 3. Specifically, the circuit breaker switch window 31 on the terminal cover 3 corresponds to the mounting base 2 and matches the manual operation surface of the circuit breaker 4 fixed on the mounting base 2, ensuring that the manual operation surface of the circuit breaker 4, which is turned off on the mounting base 2, can extend out of the terminal cover 3, allowing the operating switch 43 on the manual operation surface to be exposed outside the terminal cover 3, facilitating user operation of the operating switch 43 controlling the circuit breaker 4.

[0040] As an optional implementation method, such as Figure 2 and Figure 5As shown, the terminal cover 3 is also provided with multiple screw through holes 32, which are symmetrically arranged on both sides of the terminal cover 3. A screw post 33 communicating with the screw through holes 32 is provided inside the terminal cover 3. The bottom shell 5 is provided with positioning holes 53 corresponding to and matching the screw posts 33. The terminal cover 3 is matched with the tail of the energy meter. When the terminal cover 3 is fixed to the bottom shell 5, the screw post 33 is positioned within the positioning hole 53. Specifically, the terminal cover 3 may have two screw through holes 32, which are symmetrically arranged on both sides of the terminal cover 3. The terminal cover 3 is provided with a screw post 33 communicating with the screw through holes 32, facilitating the insertion of the screw post 33 into the corresponding positioning hole 53 on the bottom shell 5 when the terminal cover 3 is installed on the bottom shell 5, thus positioning and installing the terminal cover 3. A screw or other connecting structure with the same connection function passes through the screw through hole 32, the screw post 33 and the positioning hole 53 in sequence. The screw is threaded to the screw post 33 and the positioning hole 53, thereby closing the terminal cover 3 on the bottom shell 5.

[0041] As an optional implementation method, such as Figure 2 As shown, the terminal cover 3 is also provided with an extension plate 34, which is located on the top of the terminal cover 3. When the terminal cover 3 is fixed on the bottom shell 5, the extension plate 34 is installed into the groove 71 of the energy meter corresponding to the extension plate 34. Specifically, the extension plate 34 matches the groove 71 on the energy meter. When the terminal cover 3 is fixed on the bottom shell 5, the extension plate 34 on the terminal cover 3 is installed into the groove 71, so that the terminal cover 3 and the top cover 7 on the energy meter are on the same horizontal plane.

[0042] As an optional implementation, the base 1 and the mounting base 2 are integrated into one unit. Specifically, the integrated structure of the base 1 and the mounting base 2 facilitates manufacturing, reduces costs, and allows the circuit breaker 4 to be easily and quickly installed on the electricity meter.

[0043] Example 2:

[0044] like Figure 6 As shown, an electricity meter includes a miniature circuit breaker mounting device for the electricity meter (as described in Embodiment 1), a base shell 5, a terminal block 6, and a top cover 7. The terminal block 6 is fixed to the base shell 5, and the top cover 7 is fixed to the base shell 5. The mounting device is fixedly connected to both the base shell 5 and the top cover 7. Specifically, the terminal block 6 is fixed to the rear of the base shell 5, and the mounting device is fixedly connected to the rear of both the base shell 5 and the top cover 7. The circuit breaker 4 is mounted and fixed to the lower end of the terminal block 6, facilitating electrical connection between the circuit breaker 4 and the terminal block 6. Simultaneously, the encapsulation of the circuit breaker 4 by the mounting device protects the circuit breaker 4, preventing wire-based electricity theft, and also saves the work of separately installing the circuit breaker 4 in the metering distribution box.

[0045] The above description is merely a preferred embodiment of the present utility model. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present utility model. Furthermore, under the teachings of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
