For example, patent document CN201917656U discloses a quick wiring device for electric energy meter calibration, which uses a plurality of terminal blocks corresponding to the positions of the single-phase smart meter terminal blocks in the shell. When wiring, the plurality of terminal blocks can be directly inserted into the single-phase smart meter terminal blocks. The wiring is simple and quick, and the operation of using multiple alligator clips separately is eliminated. When calibrating and wiring batches of identical electric energy meters one by one, the wiring efficiency is greatly improved.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification of this application and the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The embodiment of the present invention provides a meter position wiring device for standard electric energy meter verification, such as Figure 1-13 As shown, the meter position wiring device for calibration of standard electric energy meters comprises: a mounting shell 1, a plurality of conductive rods 2 arranged in the mounting shell 1, and a plurality of terminal posts 3 respectively contacting the plurality of conductive rods 2, one end of each of the plurality of conductive rods 2 extending outside the mounting shell 1, for contacting the meter position of the standard electric energy meter to be calibrated for conduction, and the plurality of terminal posts 3 are bent rods, and one end of each of the terminal posts 3 also extending outside the mounting shell 1, for connecting the connection line of the calibration equipment; wherein each terminal post 3 is provided with a lateral adjustment mechanism and a fixing assembly, the lateral adjustment mechanism is used to move the terminal post 3 laterally to adjust the distance between adjacent terminal posts 3, and the fixing assembly is used to fix the position of the terminal post 3 and the conductive rod 2 after adjusting the distance between adjacent terminal posts 3 and adjacent conductive rods 2 according to the meter position of the standard electric energy meter to be calibrated; the mounting shell 1 is also provided with two height adjustment mechanisms, so as to adjust the height of the conductive rod 2 by adjusting the height of the mounting shell 1 according to the meter position of the standard electric energy meter to be calibrated.

[0039] In this embodiment, the device can effectively adapt to the meter position wiring requirements of different types of electric energy meters and improve the wiring efficiency. The wiring device mainly includes a mounting shell 1, a plurality of conductive rods 2 and a plurality of terminal posts 3. The conductive rods 2 are arranged in the mounting shell 1, and one end thereof extends outside the mounting shell 1, and is used to contact the meter position of the standard electric energy meter to be calibrated for conduction; the terminal posts 3 are respectively in contact with the conductive rods 2, and they adopt a bent rod design, and one end also extends outside the mounting shell 1, which is convenient for connecting the connection line of the calibration equipment;

[0040] The core innovation of the present invention lies in the lateral adjustment mechanism and the fixing assembly equipped on each terminal 3. The lateral adjustment mechanism can move the terminal 3 laterally, thereby realizing the flexible adjustment of the distance between adjacent terminals 3. In this way, no matter how the meter position spacing of the electric energy meter to be calibrated changes, it can be adapted by adjusting the position of the terminal 3. The fixing assembly is used to fix the position of the terminal 3 and the conductive rod 2 after the adjustment is completed, to ensure stability during the calibration process.

[0041] In addition, the mounting shell 1 is also equipped with two height adjustment mechanisms. These two mechanisms can adjust the overall height of the mounting shell 1 according to the height of the meter position when the standard electric energy meter to be calibrated is fixed on the calibration table panel, thereby adjusting the height of the conductive rod 2. In this way, whether it is a high meter position or a low meter position, it can be adapted by adjusting the height of the mounting shell 1.

[0042] The use of the meter connection device will greatly improve the flexibility and convenience of electric energy meter calibration, especially for the calibration work that needs to handle batches of electric energy meters of multiple models (that is, when the number of electric energy meters of each model is relatively large), its practicality and economic benefits are particularly significant.

[0043] In a further preferred embodiment of the present invention, long seats 6 are fixedly installed on the top inner wall and the bottom inner wall of the mounting shell 1, and rectangular slide grooves are opened on both sides. The lateral adjustment mechanism includes: a mounting block 4, which is fixedly sleeved on the terminal 3 and is made of insulating material; two limit blocks 5, which are respectively arranged on the top and bottom of the mounting block 4, are integrally formed with the mounting block 4, and are slidably connected to the inner walls on both sides of the rectangular slide grooves of the two long seats 6, so that under the action of external force, the limit blocks 5 slide laterally in the rectangular slide grooves.

[0044] In the present embodiment, a long seat 6 is fixedly installed on the top inner wall and the bottom inner wall of the mounting shell 1, and a rectangular slide groove is provided inside the long seat 6. The design of these rectangular slide grooves enables the lateral adjustment mechanism to operate more accurately in the lateral direction. The lateral adjustment mechanism is mainly composed of a mounting block 4 and two limit blocks 5. The mounting block 4 is made of insulating material and is fixedly mounted on the terminal 3 to ensure that the electrical performance of the terminal 3 is not affected during the adjustment process. The two limit blocks 5 are respectively arranged at the top and bottom of the mounting block 4, and they are integrally formed with the mounting block 4, thereby ensuring the stability and reliability of the structure. These limit blocks 5 are slidably connected to the inner walls on both sides of the rectangular slide groove on the long seat 6, so that under the action of external force, the mounting block 4 can drive the terminal 3 to slide laterally in the rectangular slide groove, thereby realizing flexible adjustment of the position of the terminal 3.

[0045] This design not only makes the adjustment of the terminal 3 more convenient and quick, but also ensures the stability and accuracy during the adjustment process. Through the lateral adjustment mechanism, the user can accurately adjust the position of the terminal 3 according to the position of the electric energy meter to be tested, thereby realizing the position adjustment of the conductive rod 2 to meet the wiring requirements of different types of electric energy meters.

[0046] After adjusting the position of the conductive rod according to the position of the connection meter of the electric energy meter, batches of standard electric energy meters of this model can be connected and calibrated one by one, which greatly improves the connection efficiency and calibration efficiency.

[0047] In summary, the meter position wiring device for standard electric energy meter calibration provided by the embodiment of the present invention realizes flexible adjustment and fixation of the position of the terminal 3 and the conductive rod 2 through the setting of the lateral adjustment mechanism. This design not only improves the accuracy and efficiency of batch calibration, but also can adapt to various types of electric energy meters, which brings great convenience to the calibration of batch standard electric energy meters.

[0048] In a further preferred embodiment of the present invention, the fixing assembly includes: a fixing screw rod 7, which is arranged on the top of the limit block 5 located above, is integrally formed with the limit block 5, and passes through a long hole horizontally opened on the top of the mounting shell 1; a hand-tightened nut 8, which is threadedly sleeved on the fixing screw rod 7 and is located on the top of the mounting shell 1.

[0049] In this embodiment, the design of the fixing component provides a reliable and convenient solution for fixing the position of the terminal 3 and the conductive rod 2. Specifically, the fixing component is mainly composed of a fixed screw rod 7 and a hand nut 8. The fixed screw rod 7 is located at the top of the upper limit block 5 and is integrally formed with the limit block 5 to ensure the stability of the structure. The fixed screw rod 7 passes through the long strip hole opened horizontally on the top of the mounting shell 1, which enables the fixed screw rod 7 to move horizontally in the long strip hole. The hand nut 8 is threadedly sleeved on the fixed screw rod 7 and is located at the top of the mounting shell 1. By rotating the hand nut 8, its position on the fixed screw rod 7 can be easily adjusted. When it is necessary to fix the position of the terminal 3 and the conductive rod 2, it is only necessary to tighten the hand nut 8 so that it fits tightly with the top of the mounting shell 1 to achieve the fixation of the terminal 3 and the conductive rod 2.

[0050] In a further preferred embodiment of the present invention, a conductive slide groove is provided at one end of the conductive terminal 3, one end of the conductive rod 2 extends into the conductive slide groove and is slidably connected to the conductive slide groove, and a telescopic component is provided on the conductive rod 2, which is used to push the mounting shell 1 to make the conductive rod 2 contact with the table position of the standard electric energy meter to be calibrated for buffering and keep it in a good contact and conduction state, and the telescopic mechanism includes: a stopper 9, which is fixedly sleeved on the conductive rod 2 and located in the mounting shell 1; a first spring 10, which is slidably sleeved on the conductive rod 2 and located between the mounting block 4 and the stopper 9.

[0051] In this embodiment, the connection mode between the conductive rod 2 and the terminal 3 is innovatively designed, and a telescopic component is introduced to improve the stability and reliability of the contact conduction state. Specifically, a conductive chute is provided at one end of the conductive terminal 3, so that one end of the conductive rod 2 can smoothly extend into the conductive chute and form a sliding connection with the conductive chute. This design not only ensures the electrical connection between the conductive rod 2 and the terminal 3, but also allows the two to move relative to each other within a certain range. In order to further improve the stability of the contact conduction state, the present invention introduces a telescopic component. The telescopic component includes a stopper 9 and a first spring 10. The stopper 9 is fixedly sleeved on the conductive rod 2 and located in the mounting shell 1, which plays a role in limiting the movement range of the conductive rod 2. The first spring 10 is slidably sleeved on the conductive rod 2 and located between the mounting block 4 and the stopper 9. When the conductive rod 2 contacts the table position of the standard electric energy meter to be calibrated, the first spring 10 can provide a certain buffering effect, reduce the impact and vibration caused by the contact, and thus protect the wiring device and the electric energy meter from damage. At the same time, the elastic force of the first spring 10 can also ensure that the conductive rod 2 maintains a good contact state with the surface, thereby avoiding the calibration error caused by poor contact.

[0052] This design not only improves the adaptability of the wiring device to the meter position of the electric energy meter, but also ensures the accuracy and stability of the verification through the buffering and contact-maintaining effects of the telescopic components.

[0053] In a further preferred embodiment of the present invention, a conductive block 12 is fixedly sleeved on the top of the conductive terminal 3 for receiving a joint of the wire connecting the calibration equipment (such as a U-shaped conductive connecting piece); a wiring screw 13 is provided on the top of the conductive terminal 3 and is integrally formed with the conductive terminal 3; a locking sleeve 14 is threadedly sleeved on the wiring screw 13 for pressing and fixing the joint of the wire connecting the calibration equipment; an insulating jacket 15 is fixedly sleeved on the locking sleeve 14 to avoid electric shock due to failure to turn off the power when the insulating jacket 15 is manually tightened.

[0054] In this embodiment, the top structure of the conductive terminal 3 is optimized by adding components such as a conductive block 12, a wiring screw rod 13, a locking sleeve 14 and an insulating jacket 15 to improve the connection stability and safety between the terminal 3 and the connecting wire of the calibration equipment.

[0055] Specifically, the top fixed sleeve of the conductive terminal 3 is provided with a receiving conductive block 12. This design can easily receive the joint of the connection wire of the calibration equipment, such as a U-shaped conductive connecting piece. The top of the conductive terminal 3 is also provided with a wiring screw 13, which is integrally formed with the conductive terminal 3, making the structure more stable and reliable. The threaded sleeve on the wiring screw 13 is provided with a locking sleeve 14. This design can realize the compression and fixation of the joint of the connection wire of the calibration equipment, so that it is fixed on the receiving conductive block 12. This structure ensures that the joint will not fall off or loosen during the calibration process, ensures the accuracy and stability of the calibration, and avoids the calibration error caused by poor contact.

[0056] In order to further improve safety, an insulating jacket 15 is fixedly mounted on the locking sleeve 14. This design allows the operator to avoid the risk of electric shock caused by accidental touch when manually tightening the locking sleeve 14, even if the power is not turned off. The insulating jacket 15 is usually made of a material with good insulation performance, such as rubber or plastic, which can effectively isolate the current and protect the safety of the operator.

[0057] In a further preferred embodiment of the present invention, the wiring device is also equipped with a sliding support mechanism for supporting the mounting shell 1 and its height adjustment mechanism, and for moving the mounting shell 1 longitudinally under external force so that the conductive rod 2 contacts the table position of the standard electric energy meter to be calibrated, the sliding support mechanism comprising: a U-shaped seat 16, wherein the inner walls on both sides of the U-shaped seat 16 are provided with sliding grooves; two sliders 17 that slide in the sliding grooves on both sides of the U-shaped seat 16, respectively, and the two sliders 17 are symmetrically arranged; two connecting seats 18 that are respectively fixedly mounted on one side of the two sliders 17 that are close to each other, the mounting shell 1 is arranged between the two connecting seats 18, and the two height adjustment mechanisms are respectively arranged on the two connecting seats 18.

[0058] In this embodiment, the wiring device is equipped with a sliding support mechanism for supporting the mounting shell 1 and its height adjustment mechanism, and moving the mounting shell 1 longitudinally under the action of an external force, so that the conductive rod 2 contacts the table position of the standard electric energy meter to be calibrated. This design not only improves the stability and reliability of the wiring device, but also makes the wiring process more convenient and efficient.

[0059] Specifically, the sliding support mechanism includes a U-shaped seat 16, two sliders 17 and two connecting seats 18. The inner walls on both sides of the U-shaped seat 16 are provided with sliding grooves for providing sliding tracks for the sliders 17. The two sliders 17 slide in the sliding grooves on both sides of the U-shaped seat 16 respectively, and are symmetrically arranged to ensure the smoothness and symmetry of the sliding. The connecting seats 18 are respectively fixedly installed on the sides where the two sliders 17 are close to each other, and the mounting shell 1 is arranged between the two connecting seats 18, thereby achieving support for the mounting shell 1. At the same time, two height adjustment mechanisms are respectively arranged on the two connecting seats 18, so as to facilitate independent adjustment of the height of the mounting shell 1 to meet the wiring requirements of the meter positions of different types of electric energy meters.

[0060] During use, the operator can push the mounting shell 1 by external force to make it move longitudinally under the support of the sliding support mechanism. Due to the sliding action of the slider 17 in the sliding groove, the movement process of the mounting shell 1 is stable and smooth, so that the conductive rod 2 can be well contacted with the table position of the standard electric energy meter to be tested.

[0061] In a further preferred embodiment of the present invention, two fixing blocks 30 are provided on both sides of the U-shaped seat 16, the bottoms of the four fixing blocks 30 are flush with the bottom of the U-shaped seat 16, and the four fixing blocks 30 are provided with mounting holes for fixing to the electric energy meter calibration table panel with bolts.

[0062] In this embodiment, two fixing blocks 30 are designed on both sides of the U-shaped seat 16, and the bottoms of the four fixing blocks 30 are kept flush with the bottom of the U-shaped seat 16. Each fixing block 30 is provided with a mounting hole, which is used to fix the wiring device on the calibration table panel of the electric energy meter by bolts. The setting of the fixing block 30 enhances the connection stability between the wiring device and the calibration table panel, so that the wiring device can be firmly fixed on the panel without loosening or displacement.

[0063] In a further preferred embodiment of the present invention, long holes are also opened on the front and rear sides of the mounting shell 1, which are used for the conductive rods 2 and the conductive terminals 3 to pass through the mounting shell 1 and allow multiple conductive rods 2 and multiple conductive terminals 3 to move horizontally.

[0064] In this embodiment, long holes are provided on both the front and rear surfaces of the mounting shell 1. The design of the long holes allows the conductive rod 2 and the conductive terminal 3 to pass through the mounting shell 1 and extend to the outside. In this way, the conductive rod 2 and the conductive terminal 3 can be electrically connected to an external device or an electric energy meter to be calibrated, thereby realizing the current or voltage transmission during the electric energy meter calibration process. Secondly, the special shape of the long holes allows the conductive rod 2 and the conductive terminal 3 to have a certain amount of movement space in the lateral direction.

[0065] In a further preferred embodiment of the present invention, the mounting shell 1 is formed by assembling a completely identical lower half shell 101 and an upper half shell 102, and connecting columns 103 are provided at the four corners of the bottom inner wall of the lower half shell 101 and the top inner wall of the upper half shell 102, and a plurality of connecting columns 103 are respectively integrally formed with the lower half shell 101 and the upper half shell 102, and the upper half shell 102 and the lower half shell 101 are fixed by threading the upper half shell 102 from the top of the upper half shell 102 onto the connecting columns 103 of the upper half shell 102 and the lower half shell 101, and the components in the mounting shell 1 are conveniently installed by combining the upper half shell 102 and the lower half shell 101.

[0066] In this embodiment, the mounting shell 1 is composed of two completely identical parts, the lower half shell 101 and the upper half shell 102 . This split design brings many benefits.

[0067] First, the bottom inner wall of the lower half shell 101 and the top inner wall of the upper half shell 102 are provided with connecting posts 103 at the four corners, and these connecting posts 103 are formed integrally with the lower half shell 101 and the upper half shell 102, respectively, to ensure the stability and reliability of the structure. By using bolts to be threadedly installed from the top of the upper half shell 102 to the connecting posts 103, the upper half shell 102 and the lower half shell 101 can be easily fixed tightly. This fixing method is not only easy to operate, but also has a firm connection, which effectively prevents the mounting shell 1 from loosening or deformation during use.

[0068] Secondly, the combined installation of the upper half shell 102 and the lower half shell 101 greatly facilitates the installation of the internal components of the installation shell 1. In the separated state, each component can be easily positioned and adjusted, and then the upper half shell and the lower half shell are combined together to complete the assembly of the entire installation shell 1. This design not only improves work efficiency, but also makes component installation more accurate and reliable.

[0069] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0070] In another embodiment of the present invention, a locking mechanism for locking the longitudinal movement of the mounting shell 1 is also installed on the two sliders 17, and the locking mechanism includes: a mounting seat 19, which is fixedly mounted on one side of the slider 17 and has multiple movable holes on the side wall of the U-shaped seat 16, and the mounting seat 19 is an inverted L-shape; a slide bar 20, which is slidably mounted on the rectangular slide hole opened on the mounting seat 19, and the slide bar 20 is a square bar; a pressure block 22 fixedly mounted on the bottom end of the slide bar 20, and the bottom end of the pressure block 22 is provided with teeth 23, and the teeth 23 are engaged with the tooth groove 31 opened at the top of the U-shaped seat 16; a second spring 21, which is slidably sleeved on the slide bar 20 and is located between the pressure block 22 and the mounting seat 19, and is used to provide downward pressure for the pressure block 22; a pull ring 24, which is fixedly mounted on the top of the slide bar 20 and is used to be pulled upward by hand when releasing the lock so that the teeth 23 of the pressure block 22 are disengaged from the tooth groove 31.

[0071] In the present embodiment, the wiring device is further optimized, especially in the longitudinal movement locking mechanism of the mounting shell 1. Specifically, a locking mechanism is installed on the two sliders 17. The main function of this mechanism is to ensure that the mounting shell 1 can be stably fixed in this position after the conductive rod 2 is in good contact with the table position of the electric energy meter to prevent it from accidentally sliding. The locking mechanism is composed of multiple components, which work together to achieve the locking function. First, the mounting seat 19 is fixedly mounted on one side of the slider 17 and passes through the movable hole opened on the side wall of the U-shaped seat 16. The shape of the mounting seat 19 is an inverted L-shape. This design not only ensures the stability of the structure, but also facilitates the installation and operation of other components.

[0072] Secondly, the slide bar 20 is slidably mounted on the rectangular slide hole opened on the mounting seat 19. The slide bar 20 is in the shape of a square bar. This design can prevent the slide bar 20 from rotating in the mounting seat 19 and ensure that it can slide smoothly. At the bottom end of the slide bar 20, a pressing block 22 is fixedly installed. The bottom end of the pressing block 22 is provided with teeth 23, and these teeth 23 can mesh with the tooth grooves 31 opened on the top of the U-shaped seat 16. When the teeth 23 mesh with the tooth grooves 31, the longitudinal movement of the mounting shell 1 is locked, thereby achieving the function of fixing the position.

[0073] In order to ensure that the pressing block 22 can always maintain downward pressure and make the teeth 23 and the tooth grooves 31 closely meshed, a second spring 21 is also provided. The second spring 21 is slidably sleeved on the slide bar 20 and is located between the pressing block 22 and the mounting seat 19. The second spring 21 is in a compressed state, generating a downward restoring force to ensure close contact between the teeth 23 and the tooth grooves 31.

[0074] Finally, in order to facilitate unlocking when needed, a pull ring 24 is fixedly installed on the top of the slide bar 20. When the installation shell 1 needs to be moved, the pull ring 24 is pulled upward by hand, and the slide bar 20 and the pressing block 22 will move upward accordingly, so that the teeth 23 are separated from the tooth grooves 31, thereby releasing the locked state.

[0075] In another embodiment of the present invention, the height adjustment mechanism includes: a connecting block 25, which is fixedly mounted on one side of the mounting shell 1, and two limit rods 27 are fixedly mounted on the top of the connecting block 25, and the two limit rods 27 are vertically slidably connected to the connecting seat 18; a screw rod 26, which is rotatably mounted on the top of the connecting block 25 and is threadedly connected to the connecting seat 18; a turning handle 28, which is assembled on the top of the screw rod 26 and is used to rotate the screw rod 26 when rotating so that the screw rod 26 can be raised and lowered on the connecting seat 18.

[0076] In this embodiment, the height adjustment mechanism is designed to achieve accurate and convenient adjustment of the height of the mounting shell 1 to meet the requirements of rapid wiring of meter positions of electric energy meters of different models.

[0077] Specifically, the height adjustment mechanism mainly includes a connecting block 25, a limiting rod 27, a screw 26 and a turning handle 28. The connecting block 25 is fixedly mounted on one side of the mounting shell 1 as a support and foundation for the entire height adjustment mechanism. Two limiting rods 27 are fixedly mounted on the top of the connecting block 25. The two limiting rods 27 are vertically slidably connected to the connecting seat 18 to ensure that the connecting seat 18 can remain stable and will not deviate during the lifting process.

[0078] The screw rod 26 is the core component of the height adjustment mechanism, which is rotatably mounted on the top of the connecting block 25 and is threadedly connected to the connecting seat 18. This design enables the connecting seat 18 to move up and down along the axis of the screw rod 26 when the screw rod 26 rotates. In this way, the height of the mounting shell 1 can be accurately adjusted.

[0079] For convenient operation, a handle 28 is also installed at the top of the screw rod 26. The handle 28 is designed so that the user can manually rotate it to drive the screw rod 26 to rotate, thereby realizing convenient adjustment of the height of the mounting shell 1. This design not only improves the convenience of operation, but also makes the height adjustment more accurate and reliable.

[0080] In summary, the height adjustment mechanism in this embodiment realizes accurate and convenient adjustment of the height of the mounting shell 1 through the coordinated action of the connecting block 25, the limiting rod 27, the screw rod 26 and the turning handle 28. This design not only improves the flexibility and adaptability of the wiring device, but also provides users with a more comfortable and convenient operating experience.

[0081] In another embodiment of the present invention, a locking nut 29 is threadedly sleeved on the screw rod 26, which is used to tighten the locking nut 29 to make it tightly against the top of the connecting seat 18 after adjusting the height of the mounting shell 1, so as to prevent the screw rod 26 from rotating at will and ensure the stability of the mounting shell 1 when adjusting the height.

[0082] In this embodiment, the stability of the height adjustment mechanism is further enhanced. In particular, a locking nut 29 is newly added to the screw rod 26.

[0083] The locking nut 29 is designed to be threadedly sleeved with the screw rod 26, which means that it can move up and down along the axial direction of the screw rod 26 and fix its position by rotation. After the height of the mounting shell 1 is adjusted to a suitable position through the threaded connection between the screw rod 26 and the connecting seat 18, the operator can hold the turning handle 28 so that it does not rotate, and then turn the locking nut 29 to move it downward and tightly abut against the top of the connecting seat 18. Through this design, the locking nut 29 can effectively prevent the screw rod 26 from rotating at will when no external force is applied. In this way, even in the presence of external vibrations or other interference factors, the mounting shell 1 can maintain its adjusted height stability and is not prone to accidental movement or loosening.

[0084] Therefore, the addition of the locking nut 29 not only improves the stability of the overall structure of the wiring device, but also enhances its reliability and safety in use. This improvement enables the operator to more conveniently adjust the height of the mounting shell 1 and ensure that its position is fixed after the adjustment is completed, thereby improving work efficiency and user experience.

[0085] In summary, compared with the related art, firstly, a lateral adjustment mechanism is provided inside the mounting shell 1, and a height adjustment mechanism is provided outside the mounting shell 1, so that the position of the conductive rod 2 can be adjusted, so that it can be quickly connected with the table position of different types of standard electric energy meters, and the position of the conductive rod 2 after adjustment is fixed by providing a fixing component and a locking nut 29, so that it can be in good contact with the table position of the electric energy meter;

[0086] By setting up the longitudinal sliding mechanism and the locking mechanism, the connection between the conductive rod 2 and the meter position of the electric energy meter is simple and convenient, which greatly improves the wiring efficiency. Especially when calibrating batch electric energy meters, the calibration efficiency is greatly improved through rapid wiring operation.
