Description

Technical Field

[0001] This utility model relates to the field of electricity meter manufacturing technology, and in particular to a reliability testing device for electricity meters. Background Technology

[0002] To ensure the reliability of electricity meters, aging tests are conducted before they leave the factory. Typically, this involves aging the meters in a high-temperature aging chamber for 72 hours to screen for early-failure components and ensure the meters function properly and meet factory standards. Traditional aging test equipment uses a vertical, double-sided meter mounting system. This increases the number of meters tested by increasing the height of the equipment, resulting in a large footprint, immobility, inconvenient operation, and complex wiring. Summary of the Invention

[0003] The purpose of this invention is to provide a reliability testing device for electricity meters, which can solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A reliability testing device for an electricity meter includes four columns, with wheels at the bottom of the four columns. Multiple storage layers are arranged between the four columns, and each storage layer has a circuit board. The circuit board is connected to a power source via wires. Multiple pin groups are evenly distributed on the circuit board and connected in parallel. Above the circuit board are multiple meter carriers corresponding to each pin group. Each meter carrier has a positioning groove for placing the electricity meter. The bottom of the positioning groove has multiple pin holes. The pins of each pin group extend into the positioning groove from the pin holes. When the electricity meter to be tested is installed in the positioning groove, the pins of the pin groups are inserted into the electricity meter.

[0005] Preferably, two adjacent meter carriers are connected to each other via a splicing structure.

[0006] Preferably, the splicing structure includes splicing protrusions and splicing grooves, which are respectively disposed on both sides of the meter carrier, and the splicing protrusions are connected to the splicing grooves of another meter carrier.

[0007] Preferably, there are two splicing grooves and two splicing protrusions, which are located on the four sides of the meter carrier.

[0008] Preferably, the splicing groove has a positioning protrusion, and the splicing protrusion has a positioning groove. When the splicing protrusion cooperates with the splicing groove of another meter carrier, the positioning protrusion is engaged in the corresponding positioning groove.

[0009] Preferably, the storage layer is provided with a wire groove for wires to pass through.

[0010] Preferably, the bottom of the lowest storage layer is provided with an electrostatic discharge chain.

[0011] Preferably, the column has multiple mounting holes evenly distributed along the height direction, and the four corners of each shelf layer are detachably installed in the mounting holes at the same height by screws to achieve a detachable connection between the shelf layer and the column.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: 1. This utility model uses a circuit board instead of wiring, with a modular design and a simple and compact structure. 2. This utility model tests the reliability of the energy meter through a multi-layer testing method, has a strong load capacity, occupies a small area, and is easy to maintain. 3. This utility model is equipped with wheels at the bottom for easy movement and convenient operation. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figures 1-6As shown, this utility model provides a reliability testing device for an electricity meter, including four columns 1, with wheels 2 at the bottom of the four columns 1, and multiple layers 3 arranged between the four columns 1. The edges of the layers are reinforced, and each layer 3 has a circuit board. The circuit board is connected to a power source via wires and integrates an aging test circuit. Multiple pin groups are evenly distributed on the circuit board and connected in parallel. Above the circuit board are multiple meter carriers 4 corresponding to the pin groups. Each meter carrier 4 has a positioning groove 5 for placing the electricity meter. The bottom of the positioning groove 5 has multiple pin holes 6. The pins of the pin groups extend into the positioning groove 5 from the pin holes 6. When the electricity meter to be tested is installed in the positioning groove 5, the pins of the pin groups are inserted into the electricity meter.

[0020] In use, the energy meter to be tested is inserted into the positioning groove 5 on the meter carrier 4. Simultaneously, the pins of the pin group at the bottom of the positioning groove 5 are inserted into the energy meter. Because the pin groups are connected in parallel, i.e., the meter carriers 4 are connected in parallel, the testing of each energy meter will not interfere with the others. The meter carriers 4 on the shelf 3 can be filled with energy meters or not. Then, the device is placed in a high-temperature aging chamber for 72 hours of aging to screen for early-failure components, achieving reliability testing of the energy meter and ensuring its normal operation and compliance with factory standards. This device uses a circuit board instead of wiring, featuring a modular design and a simple, compact structure. Furthermore, it tests the reliability of the energy meter through multi-layer testing, has a strong load capacity, occupies a small area, and is easy to maintain. The bottom of the device is equipped with wheels 2 for easy movement and convenient operation.

[0021] Preferably, two adjacent meter carriers 4 are connected to each other by a splicing structure. Specifically, the splicing structure includes a splicing protrusion 7 and a splicing groove 8. The splicing protrusion 7 and the splicing groove 8 are respectively provided on both sides of the meter carrier 4. The splicing protrusion 7 is connected to the splicing groove 8 of another meter carrier 4. In this way, two adjacent meter carriers 4 can be assembled together, so that multiple meter carriers 5 are connected into one piece. During the movement of this utility model, the meter carriers 4 will not move, and there is no need to set a fixing structure on the storage layer 3. The structure is simple and compact.

[0022] Preferably, there are two splicing grooves 8 and two splicing protrusions 7, which are located on the four sides of the meter carrier 4, so that multiple meter carriers 4 can be connected by extending to the four sides.

[0023] Preferably, the splicing groove 8 has a protruding positioning protrusion 9, and the splicing protrusion 7 has a recessed positioning groove 10. When the splicing protrusion 7 mates with the splicing groove 8 of another meter carrier 4, the positioning protrusion 9 engages with the corresponding positioning groove 10. The splicing groove 8 and the splicing protrusion 7 are simply joined together, and the positioning protrusion 9 engages with the positioning groove 10, thus reliably connecting two adjacent meter carriers 4 together.

[0024] Preferably, the storage layer 3 is provided with a wire groove 11 for wires to pass through, which facilitates wiring.

[0025] Preferably, the bottom of the lowest storage layer 3 is provided with an electrostatic discharge chain 12 to eliminate static electricity.

[0026] Preferably, the column 1 has multiple mounting holes evenly distributed along the height direction. The four corners of each shelf 3 are detachably installed in the mounting holes at the same height by screws, so that the shelf 3 and the column 1 are detachably connected. The height of the shelf 3 can be adjusted to meet the reliability test of electricity meters of various heights. Moreover, the shelf 3 and the column 1 can be disassembled, making assembly and transportation convenient.

[0027] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
