[0002] With the transformation of the national grid, the grid company began to vigorously promote the smart grid, which greatly increased the use of energy meters and meter boxes. In addition, the State Grid clearly stipulates that "the installation of energy meters should be achieved through special connectors for energy meters, and wires should not be directly connected to energy meters.

[0003] The existing electric energy meter connector includes a wiring seat, a wiring terminal arranged on the wiring seat, a rotating plate hinged to the wiring seat, and a conductive terminal head arranged on the rotating plate. The conductive terminal head is against the wiring terminal to enable the conductive terminal head to be energized. However, after the existing electric energy meter is inserted into the conductive terminal head, the upper end of the electric energy meter lacks a fixed point, so the electric energy meter is easy to tilt forward, and then the conductive terminal is subjected to radial pressure, resulting in bending and deformation of the conductive terminal. Therefore, the applicant has made a useful design and found a solution to the above problem. The technical solution to be introduced below is produced in this context. Summary of the invention

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0036] Reference example Figures 1 to 8 A fixed and reliable electric energy meter connector comprises a connector body 1 and a flip assembly 2 hinged to the connector body 1. A liftable clip 3 is provided above the connector body 1 away from the flip assembly 2. The clip 3 is provided with an elastic portion 31. The connector body 1 is provided with a cylinder 11 which abuts against the elastic portion 31 to make the elastic portion 31 contract toward the middle of the clip 3 to store energy. The clip 3 is provided with a hook portion 32, and the hook portion 32 is provided with an inclined surface 321 for guiding the clip 3 to descend.

[0037] It is worth mentioning that the connector body 1 is provided with a concave cavity 12 for accommodating the snap member 3, and limiting grooves 13 are provided on both sides of the concave cavity 12. A first limiting portion 14 is provided above the concave cavity 12. The concave cavity 12 is also provided with a guide groove 15, and the guide groove 15 is provided with a chamfer 4. The connector body 1 is provided with an elastic barb 17. The limiting groove 13 provides a guide for the lifting and lowering of the snap member 3. The first limiting portion 14 limits the rising distance of the snap member 3. The guide groove 15 further provides a guide for the lifting and lowering of the snap member 3. When the snap member 3 is assembled with the electric energy meter 5 connector, the chamfer 4 guides the snap member 3 to enter the concave cavity 12;

[0038] It is worth mentioning that the cylinder 11 is disposed in the concave cavity 12, and a second limiting portion 16 is disposed on one side of the cylinder 11, and the second limiting portion 16 limits the rising distance of the buckle 3;

[0039] It is worth mentioning that protrusions 33 are provided on both sides of the buckle 3 and are slidably arranged in the limiting groove 13. The buckle 3 is provided with two through holes 34. One end of the elastic part 31 is arranged in the through hole 34 and extends in the direction of the cylinder 11. A limiting block 35 is provided on one side of the elastic part 31 and abuts against the second limiting part 16. The protrusion 33 is used in conjunction with the limiting groove 13. The elastic part 31 is arc-shaped. One end of the elastic part 31 is connected to the through hole 34, which is convenient for the elastic part 31 to shrink inwardly and store energy better. The limiting block 35 cooperates with the second limiting part 16.

[0040] It is worth mentioning that the buckle 3 is provided with a guide block 36, which is slidably arranged in the guide groove 15. The buckle is also provided with a support portion 37, which is vertically arranged with the buckle 3. The support portion 37 abuts against the first limiting portion 14. The guide block 36 is used in conjunction with the guide block 36, and the support portion 37 provides support for the hook portion 32.

[0041] It is worth mentioning that the hook portion 32 is arranged on the top of the support portion 37, and the inclined surface 321 is arranged on the surface of the hook portion 32 abutting against the hook portion 32 when the hook portion 32 enters or separates from the hook groove 51 of the electric energy meter 5. The inclined surface 321 is designed as described above to improve the convenience of operation when the electric energy meter 5 is connected to or separated from the buckle 3;

[0042] It is worth mentioning that the flip assembly 2 includes a base 21 and conductive terminal heads 22 arranged in a row and fixed on the base 21. The base 21 is hinged to both sides of the connector body 1. The base 21 is provided with a back plate 211, and the back plate 211 is provided with a groove 212. The barb 17 is buckled in the groove 212. The conductive terminal head 22 is connected and fixed to the electric energy meter 5 by an interference fit. The base 21 is connected and fixed to the connector body 1 by the elastic barb 17 buckled on the groove 212 to prevent the base 21 from rotating.

[0043] It is worth mentioning that the buckle 3 is made of plastic, which greatly reduces the production cost.

[0044] The use principle of the utility model is now described as follows:

[0045] As attached Figure 3 As shown, the electric energy meter 5 is plugged into the base 21, and the electric energy meter 5 is pushed to rotate the base 21 to reset. The barb 17 is pressed by the back plate 211 to press it down, so that the back plate 211 can enter. The barb 17 releases its elastic force to buckle in the groove 212, completing the connection between the base 21 and the lower end of the connector body 1.

[0046] At the same time, the hook groove 51 on the back of the electric energy meter 5 abuts against the inclined surface 321 of the hook part 32, squeezing the buckle 3 to make it fall, and the cylinder 11 makes the elastic part 31 contract toward the middle of the buckle 3 to store energy. When the hook part 32 enters the hook groove 51, the hook part 32 is no longer subject to resistance, and the elastic part 31 releases the elastic force, so that the hook part 32 enters the hook groove 51 from the bottom, completing the fixing of the buckle 3 to the upper end of the electric energy meter 5;

[0047] When the hook portion 32 needs to be separated from the electric energy meter 5, the electric energy meter 5 only needs to be pulled, and the latch 3 can be moved downward through the inclined surface 321 of the hook portion 32 to complete the step of separating the connection points. The above-mentioned structural design can overcome the problem that the electric energy meter 5 tilts forward, causing the conductive terminal to be deformed by its radial pressure.

[0048] The above design scheme can enable the product to achieve the advantages of reliable fixation, convenient operation and low production cost.

[0049] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
