The insulating base is also provided with a first connection structure, which allows the test component to be detachably installed on the electricity meter or the smart detection terminal.

[0006] The advantages of the above technical solution are as follows: the first and second conductive ends of the test conductor connect the test end of the meter and the test end of the smart detection terminal, thereby achieving the purpose of data transmission for power-on testing of the meter. Furthermore, the use of an insulating base as the mounting carrier for the test conductor achieves the purpose of modular design of the test component, allowing it to be independently installed on the meter or smart detection terminal. A first connection structure is set on the insulating base, which allows the test component to be detachably installed on the meter or smart detection terminal, thus enabling the test component to be disassembled and replaced.

Detailed Implementation

[0037] To more clearly illustrate the technical solutions in the embodiments of this utility model and / or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, references to orientation only indicate the relative positional relationship between the components, not their absolute positional relationship.

[0038] Please see Figures 1 to 11 As shown, a test assembly for an electricity meter includes an insulating base 1 and test conductors 2 mounted on the insulating base 1. At least two test conductors 2 are arranged side-by-side on the insulating base 1. The two ends of each test conductor 2 are respectively designated as a first conductive end 3 and a second conductive end 4. The first conductive end 3 and the second conductive end 4 are used to connect the test end of the electricity meter and the detection end of a smart detection terminal. The insulating base 1 also has a first connecting structure 5, which allows the test assembly to be detachably mounted on the electricity meter or the smart detection terminal. In this structure, the first conductive end 3 and the second conductive end 4 of the test conductor 2 connect the test end of the electricity meter and the detection end of the smart detection terminal, thereby achieving the purpose of data transmission for testing the electricity meter. Furthermore, using the insulating base 1 as the mounting carrier for the test conductors achieves the purpose of a modular design structure for the test assembly, allowing it to be independently mounted on the electricity meter or the smart detection terminal. The first connecting structure 5 on the insulating base 1 allows the test assembly to be detachably mounted on the electricity meter or the smart detection terminal, thus enabling the test assembly to be disassembled and replaced. The overall structural design is reasonable.

[0039] In this embodiment, the insulating base 1 is further provided with a first cavity 6. The front and rear ends of the first cavity 6 are through-connected. The first cavity 6 is provided corresponding to the test guide 2. The first cavity 6 is used to fix the test guide 2 on the insulating base 1. In the above structure, the first cavity 6 is set in such a way that the test guide 2 is not completely exposed outside the insulating base 1. More specifically, the test guide 2 and the insulating base 1 will have a through-and fixed fit structure. This method allows the operator to take the test component through the upper and lower ends of the insulating base 1, making the operation relatively safe and the structural design reasonable.

[0040] In this embodiment, the insulating base 1 includes an upper base 7 and a lower base 8. A second connecting structure 9 is provided between the upper base 7 and the lower base 8. The first cavity 6 is provided with a first upper cavity 10 and a first lower cavity 11. The first upper cavity 10 is formed on the upper base 7, and the first lower cavity 11 is formed on the lower base 8. In the above structure, the insulating base 1 adopts a structure composed of the upper base 7 and the lower base 8, so that the first upper cavity 10 and the first lower cavity 11 constituting the first cavity 6 are respectively formed on the upper base 7 and the lower base 8, which makes the installation of the test guide 2 reasonable and convenient, and also makes the layout design of the insulating base 1 reasonable.

[0041] In this embodiment, the second connecting structure 9 includes a hook, a slot, a positioning block, and a positioning groove. The hook and the slot cooperate with each other, and the positioning block and the positioning groove cooperate with each other. The upper body 7 and the lower body 8 are detachable in the above manner, which facilitates the replacement of the test guide core 2. Of course, the second connecting structure 9 can also be a welded connection structure. The connection between the upper body 7 and the lower body 8 can be achieved by setting welding ribs, welding grooves, and other structures.

[0042] In this embodiment, a second cavity 12 is provided at the front end of the insulating base 1. The second cavity 12 is provided corresponding to the test conductor 2, and the second cavity 12 is also provided to connect the first cavity 6 and the front end of the insulating base 1. The first cavity 6 cooperates with the first conductive end 3, and the second cavity 12 cooperates with the second conductive end 4. In the above structure, the method of using the first cavity 6 and the second cavity 12 to cooperate with the first conductive end 3 and the second conductive end 4 respectively makes the use of the test conductor 2 safer. More specifically, the setting of the first cavity 6 can make the installation of the test conductor 2 more stable on the one hand, and make it less likely for the adjacent first conductive ends 3 to conduct. By additionally setting the second cavity 12, it is also difficult for the adjacent second conductive ends 4 to conduct, thereby ensuring the reliability of data transmission during power-on testing.

[0043] In this embodiment, the second cavity 12 is provided with a second upper cavity 13 and a second lower cavity 14. The second upper cavity 13 is formed on the upper seat 7 and the second lower cavity 14 is formed on the lower seat 8. In the above structure, the second upper cavity 13 and the second lower cavity 14 constituting the second cavity 12 are respectively formed on the upper seat 7 and the lower seat 8, which makes the installation of the test guide 2 more reasonable and convenient, and also makes the layout design of the insulating seat 1 more reasonable.

[0044] In this embodiment, the first connecting structure includes a connector 15 and an elastic member 16. The insulating base 1 also has a third cavity 17. The front or rear end of the third cavity 17 is through-hole to allow the outer end of the connector 15 to extend out. The outer end of the connector 15 has a fixing protrusion 18. The third cavity 17 also has an upward-through elongated groove 19. The upper end of the connector 15 has a pressing protrusion 20 passing through the elongated groove 19. The elastic member 16 is connected between the bottom of the third cavity 17 and the bottom of the connector 15, and the elastic member 16 is configured to cooperate with the pressing protrusion 20. In this design, the fixed protrusion 18 enables a reliable connection between the test component and the meter or smart detection terminal. The elastic element 16 facilitates the fixing and disassembly of the connector 14, making it easier to use. The pressing protrusion 20 allows the operator to quickly disassemble the test component by simply pressing it, simplifying the operation and preventing destructive disassembly. The third cavity 17 effectively limits the installation position of the connector 15, making its use more reasonable.

[0045] In this embodiment, the rear end of the third cavity 17 is through-hole, meaning that the connector 15 protrudes from the rear end of the insulating base 1. The outer end of the connector 15 is also designed as a hook, with the fixing protrusion 18 serving as the hook. The connector 15 engages with the test terminal of the meter, and the first conductive terminal 3 also engages with the test terminal of the meter. More specifically, the outer end of the connector 14 is inserted into the test terminal of the meter and fixed by the fixing protrusion 18. Since the insulating base 1 is composed of an upper base 7 and a lower base 8, the third cavity 17 also consists of a third upper cavity and a third lower cavity to facilitate the installation of the connector 15 and the elastic member 16. The third upper cavity is located on the upper base 7, and the third lower cavity is located on the third lower base 8. The elastic member 16 is also positioned with the connector 15 positioned relative to the bottom rear end of the pressing protrusion 20, ensuring a reasonable pressing action.

[0046] In this embodiment, a first positioning protrusion 21 is provided at the bottom of the inner end of the connector 15. The first positioning protrusion 21 is positioned opposite to the front side of the pressing protrusion 20. A first positioning recess 22 is provided on the bottom of the third cavity 17. The first positioning recess 22 is provided on the third lower cavity of the lower seat 8. More specifically, the first positioning recess 22 and the third lower cavity are structurally consistent. The first positioning protrusion 21 and the first positioning recess 22 cooperate. In the above structure, by cooperating with the first positioning protrusion 21 and the first positioning recess 22, the pressing protrusion 20 is pressed, and the connector 15 will be positioned and oscillated with the first positioning protrusion 21 as the fulcrum. The connector 15 has a good performance and a reasonable structural design.

[0047] In this embodiment, the bottom of the connector 15 is provided with a second positioning protrusion 23 at the rear side of the first positioning protrusion 21, and the bottom of the third cavity 17 is provided with a corresponding second positioning recess 24. Since the third lower cavity and the first positioning recess 22 have the same structure and are both located on the lower seat 8, the second positioning recess 24 is also formed on the lower seat 8 and is located inside the first positioning recess 22 (in the third lower cavity). The elastic member 16 is set as a spring, one end of the elastic member 16 is sleeved on the second positioning protrusion 23, and the other end of the elastic member 16 is located inside the second positioning recess 24. In the above structure, the setting of the second positioning protrusion 23 and the second positioning recess 23 effectively limits the position of the elastic member 16. When the elastic member 16 is deformed by force, it is not easy to twist, and the effect on the connector 15 is more stable. Therefore, the connector 15 has a better performance and a reasonable structural design.

[0048] In this embodiment, a third positioning recess 25 is provided on the first upper cavity 10 and / or the first lower cavity 11, and a third positioning protrusion 26 is provided on the first conductive end 3. The third positioning protrusion 26 cooperates with the third positioning recess 25. The third positioning protrusion 26 has an annular structure. Therefore, a third positioning recess 25 is formed on both the first upper cavity 10 and the first lower cavity 11. In the above structure, the cooperation between the third positioning protrusion 26 and the third positioning recess 25 makes the installation of the test guide core 2 more stable, the connection with the insulating seat 1 more firm, the use effect better, and the structural design reasonable.

[0049] In this embodiment, the first conductive end 3 or the second conductive end 4 is set as a wiring frame structure. The first conductive end 3 or the second conductive end 4 of the wiring frame structure is also provided with a fixing screw 27. In the above structure, one end of the test core 2 adopts a wiring frame structure, and the inserted wire or core can be easily and quickly fixed by the fixing screw 27, making it more convenient to use. Therefore, the first connection structure 5 and the wiring frame structure with fixing screw 27 achieve a dual fixing effect, which also makes the connection stability between the test component and the meter or smart intelligent detection terminal better.

[0050] In this embodiment, the second conductive end 4 and the detection end of the intelligent detection terminal are used in combination. The second conductive end 4 is also set as a wiring frame structure. The second conductive end 4 of the wiring frame structure and the first connecting structure 5 are distributed on both sides of the insulating seat 1. At the same time, the upper end of the upper seat 7 with the second upper cavity 13 is set as a hollowed-out method to facilitate the operator to operate the fixing screw 27.

[0051] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
