[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment:

[0029] Please refer to Figures 1-6, the present utility model provides a technical solution:

[0030] The metering box electric energy meter connector includes a fixed frame main body 1. Inside the fixed frame main body 1, multiple groups of contact plugs 2 are provided. Inside the contact plugs 2, an elastic expansion component 3 is provided. And the contact plugs 2 are connected to the fixed frame main body 1 through fixing screws. At one end of the fixed frame main body 1 away from the contact plugs 2, two groups of installation components 4 are provided. Inside the installation components 4, a fixed cylinder 5 is provided. Inside the fixed cylinder 5, a fixed rod 6 is provided. And the fixed cylinder 5 is connected to the installation components 4 through the fixed rod 6;

[0031] The elastic expansion component 3 is used to perform an internal expansion process on the contact plugs 2;

[0032] Further, the elastic expansion component 3 is composed of a connecting ring 7, a moving block 8, an annular spring 9, a rotating rod 10 and a guide rod 11. The connecting ring 7 is located inside the contact plug 2. Multiple groups of moving blocks 8 are all slidably connected inside the connecting ring 7. The annular spring 9 is located outside the connecting ring 7 and outside multiple groups of moving blocks 8. The rotating rod 10 is rotatably connected inside the fixed frame main body 1 and at one end close to the contact plug 2. The guide rod 11 is rotatably connected to one end of the rotating rod 10 close to the connecting ring 7. When the contact plug 2 is connected to the electric energy meter, through the elastic expansion component 3, the inside of the contact plug 2 can be expanded, so that the contact plug 2 can be stably clamped inside the electric energy meter, preventing loosening between the contact plug 2 and the electric energy meter, thus resulting in problems of poor reliability and short service life.

[0033] Among them, connection grooves are opened on the outer sides of the connecting ring 7 and the moving block 8. The internal structure size of the connection groove is designed to correspond to the external structure size of the annular spring 9. The connecting ring 7 and the moving block 8 are both connected to the annular spring 9 through the connection grooves. Connecting the annular spring 9 with multiple groups of connection grooves enables the annular spring 9 to be connected to the connecting ring 7 and the moving block 8. When the moving block 8 loses the external force pressure, through the cooperation of the annular spring 9 and the connecting ring 7, the moving block 8 can be reset, driving the contact plug 2 to close, so that it can be displaced from inside the electric energy meter.

[0034] Secondly, the external structure size of the guide rod 11 is designed to correspond to the internal structure size of the connecting ring 7. The rotating rod 10 is connected to the moving block 8 through the guide rod 11. One end of the moving block 8 away from the connecting ring 7 is connected to the contact plug 2. Connecting the guide rod 11 with the connecting ring 7 enables the guide rod 11 to be connected to the moving block 8 inside the connecting ring 7. Through the guide rod 11, the moving block 8 can be driven to displace, so that the moving block 8 can perform an expansion operation on the contact plug 2.

[0035] Furthermore, a connecting shell 12 is provided at one end of the rotating rod 10 away from the guiding rod 11. A first compression spring 13 is arranged inside the connecting shell 12. The rotating rod 10 is connected to the first compression spring 13 through a pressing block. One end of the first compression spring 13 away from the pressing block is fixedly connected to the connecting shell 12. Connecting the first compression spring 13 and the pressing block enables the first compression spring 13 to be connected to the rotating rod 10. When the external force on the rotating rod 10 disappears, the pressing block is driven to displace by the first compression spring 13, so that the pressing block can drive the rotating rod 10 to rotate, thereby enabling the guiding rod 11 to displace and move out of the inside of the connecting ring 7, and no longer pressing on the moving block 8. When the contact plug 2 is connected to the electric energy meter, the contact plug 2 is displaced into the inside of the electric energy meter. When the contact plug 2 is displaced into the inside of the electric energy meter, the rotating rod 10 is forced by the electric energy meter and rotates, driving the guiding rod 11 to displace, so that the guiding rod 11 is displaced into the inside of the connecting ring 7, driving multiple groups of moving blocks 8 to displace, expanding the inside of the contact plug 2, enabling the contact plug 2 to be stably clamped inside the electric energy meter, and preventing loosening between the contact plug 2 and the electric energy meter, thus avoiding problems such as poor reliability and short service life.

[0036] The installation component 4 is used to quickly connect the fixing frame body 1 and the fixing cylinder 5.

[0037] Furthermore, the installation component 4 consists of a connecting rod 14, a receiving groove 15, a moving groove 16, a limiting block 17, a second compression spring 18 and a sliding rod 19. The connecting rod 14 is located inside the fixing frame body 1 and near one end of the fixing cylinder 5. The receiving groove 15 is opened inside the connecting rod 14. Two groups of moving grooves 16 are both opened inside the receiving groove 15. The limiting block 17 is slidably connected inside the moving groove 16. The second compression spring 18 is located outside the limiting block 17 and inside the moving groove 16. The sliding rod 19 is located at one end of the limiting block 17 away from the second compression spring 18. When it is necessary to install the fixing frame body 1 inside the metering box, the installation component 4 can facilitate the installation of the fixing frame body 1 inside the metering box. Similarly, during disassembly, it can be easily disassembled and removed from the inside of the metering box.

[0038] Furthermore, the internal structure size of the accommodation groove 15 is designed to correspond to the external structure size of the fixed rod 6. The fixed rod 6 is connected to the limiting block 17 through the accommodation groove 15. The second compression spring 18 is connected to the limiting block 17 through the moving groove 16. One end of the sliding rod 19 away from the limiting block 17 is slidably connected to the accommodation groove 15. The connecting rod 14 is connected to the fixed cylinder 5, so that the accommodation groove 15 can be displaced to the outside of the fixed rod 6. Rotating the connecting rod 14 drives the accommodation groove 15 to rotate, so that the limiting block 17 can be displaced to the outside of the fixed rod 6. The second compression spring 18 can drive the limiting block 17 to displace, so that the limiting block 17 can contact the fixed rod 6, and the fixed rod 6 is limited inside the accommodation groove 15, so that the connecting rod 14 can be connected to the fixed cylinder 5. The fixing frame body 1 is installed inside the metering box. When the limiting block 17 is displaced, the sliding rod 19 can guide it to prevent deviation, which may affect the limitation of the fixed rod 6.

[0039] In this embodiment, the implementation scenario is as follows: In actual use, when the contact plug 2 is connected to the electric energy meter, the contact plug 2 is displaced into the electric energy meter. When the contact plug 2 is displaced into the electric energy meter, the rotating rod 10 is subjected to the force from the electric energy meter and rotates, driving the guide rod 11 to displace, so that the guide rod 11 is displaced into the inner part of the connecting ring 7, driving a plurality of moving blocks 8 to displace, expanding the inside of the contact plug 2, so that the contact plug 2 can be stably clamped inside the electric energy meter, preventing looseness between the contact plug 2 and the electric energy meter, and thus there are problems of poor reliability and short service life. When the fixing frame body 1 needs to be installed inside the metering box, the connecting rod 14 is connected to the fixed cylinder 5, so that the accommodation groove 15 can be displaced to the outside of the fixed rod 6. Rotating the connecting rod 14 drives the accommodation groove 15 to rotate, so that the limiting block 17 can be displaced to the outside of the fixed rod 6. The second compression spring 18 can drive the limiting block 17 to displace, so that the limiting block 17 can contact the fixed rod 6, and the fixed rod 6 is limited inside the accommodation groove 15, so that the connecting rod 14 can be connected to the fixed cylinder 5. The fixing frame body 1 is installed inside the metering box. The installation assembly 4 can facilitate the installation of the fixing frame body 1 inside the metering box. Similarly, during disassembly, it can be easily disassembled and removed from the inside of the metering box. Compared with the existing electric energy meter connector, the present utility model can improve the overall practicability of the electric energy meter connector through the design.
