Description

Technical Field

[0071] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0072] In the description of the present invention, it should be understood that the directions or positional relationships indicated by the directions, such as up, down, front, back, left, and right, are based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0073] In the description of the present invention, "several" means more than one, "plurality" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0074] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0075] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0076] In existing technology, electricity meter calibration equipment typically utilizes multiple parallel workstations to meet the testing needs of different types of meters. Horizontally arranging workstations results in excessive production line length, while vertically stacked arrangements result in excessive equipment height. Both layouts suffer from low space utilization and difficult operation and maintenance, making them particularly challenging to implement in high-density production lines or limited space.

[0077] In order to solve the above problems, the present application proposes a meter socket. Figure 1 and Figure 2As shown, in the first embodiment, the meter docking station 1000 includes a mounting station 100, a first probe assembly 210, and a second probe assembly 220. The first probe assembly 210 includes a first probe seat 211 and a first probe group 212 fixedly connected to the first probe seat 211. The second probe assembly 220 includes a second probe seat 221 and a second probe group 222 fixedly connected to the second probe seat 221. The first probe group 212 and the second probe group 222 are spaced apart at the top of the mounting station 100 along the second direction. The first probe seat 211 and the second probe seat 221 can respectively drive the first probe group 212 and the second probe group 222 to extend or retract along the first direction, thereby allowing the first probe group 212 and the second probe group 222 to each have two movable positions. The arrangement direction of the first probe group 212 and the second probe group 222 form a spatial intersection with their movement direction, for example, they can be arranged orthogonally or at an acute angle. The meter docking station 1000 forms at least two sets of calibration modes through different position combinations.

[0078] Specifically, the meter dock 1000 can implement any two of the first mode, the second mode, and the third mode, or all of the verification modes.

[0079] When the meter docking station 1000 is in the first mode, the first probe group 212 is located at the first position, and the second probe group 222 is located at the third position. The first probe group 212 and the second probe group 222 are used to connect to the first terminal at the same time.

[0080] When the docking station 1000 is in the second mode, the first probe group 212 is located at the first position for docking with the second terminal, and the second probe group 222 is located at the fourth position with a gap therebetween.

[0081] When the docking station 1000 is in the third mode, the second probe group 222 is located at the third position for docking with the third terminal, and the first probe group 212 is located at the second position to form a gap with the third terminal.

[0082] This solution uses the first probe seat 211 to drive the first probe group 212 to extend or retract, and the second probe seat 221 to drive the second probe group 222 to extend or retract. By utilizing the combined changes in the positions of the movable probe groups, it is possible to achieve compatible detection of multiple types of terminals within a single station, avoiding the safety hazards brought by the stacked structure. The movement direction of the first probe seat 211 and the second probe seat 221 is parallel to the connection direction between the meter socket 1000 and the terminal, both in the front-to-back direction. In addition, in each verification mode, the probe group corresponding to the terminal interface position on the meter socket 1000 is extended, and the remaining probe groups are retracted, avoiding the collision of the probe groups with mismatched terminals during verification, further improving safety.

[0083] For example, the meter socket 1000 proposed in this embodiment can connect to different types of China Southern Power Grid low-current terminals by switching the positions of the first probe group 212 and the second probe group 222. Specifically, when the first probe group 212 is extended to the first position and the second probe group 222 is extended to the third position, the meter socket 1000 can connect to a distribution transformer monitoring and metering terminal and a concentrator, that is, the first terminal serves as a monitoring and metering terminal or a concentrator; when the first probe group 212 is retracted to the second position and the second probe group 222 is extended to the third position, the meter socket 1000 can connect to a low-current load management terminal, that is, the third terminal serves as a low-current load management terminal.

[0084] Of course, the arrangement of the first probe group 212 and the second probe group 222 can be designed to be connected to different terminals, and this application does not limit this.

[0085] Wherein, the first direction is the front-back direction, and the second direction is the left-right direction. The first probe seat 211 and the second probe seat 221 can be manually moved to realize the position switching of the first probe group 212 and the position switching of the second probe group 222, and the positions of the first probe seat 211 and the second probe seat 221 are locked after switching the positions, so as to keep the positions of the first probe group 212 and the second probe group 222 stable during the verification process. The position switching of the first probe seat 211 and the position switching of the second probe seat 221 can also be automatically switched by the corresponding driving component. By obtaining the type of the target terminal, the driving component can drive the first probe seat 211 and the second probe seat 221, thereby driving the first probe group 212 and the second probe group 222 to move to the desired position to match the type of the target terminal. The driving component can adopt a cylinder, a motor, etc.

[0086] It should be noted that if Figure 1 and Figure 2As shown, the meter docking station 1000 generally further includes a base 500, a third probe group 600, a fourth probe group 700 and a third driving member 800. The mounting seat 100 is slidably connected to the base 500 along the front-to-back direction, and the third probe group 600 and the fourth probe group 700 are both fixedly connected to the mounting seat 100; one end of the third driving member 800 is connected to the base 500, and the other end of the third driving member 800 is connected to the mounting seat 100. The third driving member 800 is used to drive the mounting seat 100 to extend forward to reach the fifth position or retract backward to reach the sixth position; specifically, in During calibration, the meter docking station 1000 determines the calibration mode by coordinating the positions of the first probe group 212 and the second probe group 222. The third driving member 800 pushes the mounting station 100 forward to the fifth position, causing the mounting station 100 to drive all the probe groups forward and connect with the corresponding terminals. For example, when the meter docking station 1000 is in the first mode, the third driving member 800 drives the mounting station 100 to move to the fifth position, and the first probe group 212, the second probe group 222, the third probe group 600, and the fourth probe group 700 all move forward and connect with the first terminal. After the calibration is completed, the third driving member 800 retracts the mounting station 100 to the sixth position, and all the probe groups are synchronously separated from the current terminal.

[0087] It should be noted that, when the type of terminal to be tested is switched, the test mode of the meter docking station 1000 needs to be switched when the mounting station 100 is in the sixth position.

[0088] The following description will be made by taking the adjustment of the positions of the first probe seat 211 and the second probe seat 221 by the corresponding driving components as an example.

[0089] In some embodiments, as Figure 1 and Figure 2As shown, the meter dock 1000 also includes a first drive assembly 300 and a second drive assembly 400. The first drive assembly 300 and the second drive assembly 400 are both mounted on the mounting base 100. The output end of the first drive assembly 300 is connected to the first probe base 211 for driving the first probe group 212 to extend to the first position or retract to the second position. The output end of the second drive assembly 400 is connected to the second probe base 221 for driving the second probe group 222 to extend to the third position or retract to the fourth position. The first probe base 211 and the second probe base 221 can both be slidably connected to the mounting base 100; alternatively, the second probe base 221 is slidably connected to the mounting base 100, and the first probe base 211 is slidably connected to the second probe base 221. The first drive component 300 and the second drive component 410 can independently adjust the positions of the first probe group 212 and the second probe group 222 without being interfered with by other factors. That is, when the first drive component 300 drives the first probe seat 211 and the first probe group 212 to move, it will not affect the movement of the second probe seat 221 and the second probe group 222. When the second drive component 400 drives the second probe seat 221 and the second probe group 222 to move, it will not affect the movement of the first probe seat 211 and the first probe group 212. The control logic is simpler.

[0090] In other embodiments, based on the situation that the second probe seat 221 is slidingly connected to the mounting seat 100 and the first probe seat 211 is slidingly connected to the second probe seat 221, one end of the first drive component 300 can also be connected to the second probe seat 221 and the other end can be connected to the first probe seat 211, one end of the second drive component 400 can be connected to the mounting seat 100, and the other end of the second drive component 400 can be connected to the second probe seat 221; this application does not limit this.

[0091] In some embodiments, there are at least two first probe groups 212, and the number of second probe groups 222 matches the number of first probe groups 212. The first and second probe groups 212, 222 are arranged alternately along the left and right sides. In the first mode, one first probe group 212 and one second probe group 222 form a detection group. The first and second probe groups 212, 222 belonging to the same detection group are connected to the same first terminal. By integrating at least two detection groups on a single meter docking station 1000, this embodiment enables simultaneous testing of multiple terminals of the same type, improving testing efficiency.

[0092] In the above embodiment, each first probe seat 211 can be driven independently or synchronously; each second probe seat 221 can be driven independently or synchronously, which is not limited in the present application.

[0093] When an independent driving scheme is adopted, each first probe seat 211 is correspondingly provided with a first driving component 300, and the first driving component 300 is used to drive the corresponding first probe seat 211, thereby driving the first probe group 212 to extend to the first position or retract to the second position; each second probe seat 221 is correspondingly provided with a second driving component 400, and the second driving component 400 is used to drive the corresponding second probe seat 221, thereby driving the second probe group 222 to extend to the third position or retract to the fourth position.

[0094] When adopting the synchronous driving scheme, the first driving component 300 includes a first driving member 310 and a first connecting member 320. One end of the first driving member 310 is connected to the mounting base 100, and the first connecting member 320 is connected to the other end of the first driving member 310 to serve as the output end of the first driving component 300. The first connecting member 320 is connected to each first probe seat 211. The first driving member 310 is used to drive the first connecting member 320 to move, so as to drive each first probe group 212 to move synchronously to the first position or the second position.

[0095] The first driver 310 is a power element that provides linear motion output and can be an electric push rod or a pneumatic cylinder. The first connector 320 is a plate-like structure rigidly connected to the multiple first probe holders 211. The first connector 320 synchronously transmits the linear motion of a single first driver 310 to all first probe groups 212, eliminating the structural redundancy caused by multiple independent drive points.

[0096] The second driving assembly 400 includes a second driving member 410 and a second connecting member 420. One end of the second driving member 410 is connected to the mounting base 100. The second connecting member 420 is connected to the other end of the second driving member 410 to serve as the output end of the second driving assembly 400. The second connecting member 420 is connected to each second probe seat 221. The second driving member 410 is used to drive the second connecting member 420 to move, so as to drive each second probe group 222 to move synchronously to the third position or the fourth position.

[0097] The combined action principle of the second driving member 410 and the second connecting member 420 is the same as that of the first driving assembly 300 , and the synchronous displacement of the second probe group 222 is achieved through a unified driving source.

[0098] The synchronous drive solution, combining a single drive source with a rigid connector, simplifies control requirements that would otherwise require multiple independent drivers into a centralized system, eliminating the control timing coordination issues and mechanical interference risks associated with multiple drive components. Furthermore, the rigid connector ensures consistent displacement of each probe group, eliminating the potential cumulative error associated with multiple independent drive points and improving the stability and reliability of the meter dock's 1000 mode switching.

[0099] Based on the above synchronous driving scheme, the first connecting member 320 includes a first connecting portion 321 and a second connecting portion 322. The first connecting portion 321 and the second connecting portion 322 are connected to form an integrated structure. The first connecting portion 321 is connected to the first driving member 310, and the second connecting portion 322 is connected to the first probe seat 211. The first connecting portion 321 synchronously transmits the movement of the first driving member 310 to the multiple first probe seats 211 and the first probe group 212 through the second connecting portion 322.

[0100] The second connecting member 420 includes a third connecting portion 421 and a fourth connecting portion 422. The third connecting portion 421 and the fourth connecting portion 422 are connected to form an integral structure. The third connecting portion 421 is connected to the second driving member 410, and the fourth connecting portion 422 is connected to the first probe base 211. The third connecting portion 421 synchronously transmits the linear motion output of the second driving member 410 to the multiple first probe bases 211 and the second probe group 222 through the fourth connecting portion 422.

[0101] Each first probe group 212 corresponds to a first probe seat 211, and each second probe group 222 corresponds to a second probe seat 221, so the first probe seats 211 and the second probe seats 221 are also arranged alternately, and the partial structure of the first connecting part 321 connecting the first probe seat 211 located in the middle and the partial structure of the second connecting part 322 connecting the second probe seat 221 located in the middle overlap in the left and right directions. In order to avoid the first connecting part 320 and the second connecting part 420 from colliding in the front and rear directions, the first connecting part 321 and the third connecting part 421 need to be staggered.

[0102] In the first example of the above embodiment, Figure 3 As shown, the first connection part 321 and the third connection part 421 can be arranged at intervals in the up and down directions, that is, the first connection part 321 of the first connection member 320 and the third connection part 421 of the second connection member 420 are arranged in layers in the up and down directions to avoid overlap of the two groups of connections in the vertical space, so that when the first connection member 320 drives the first probe seat 211 and the first probe group 212 to move or when the second connection member 420 drives the second probe seat 221 and the second probe group 222 to move, the first connection part 321 and the third connection part 421 do not interfere with each other.

[0103] For example, the installation heights of the first probe seat 211 and the second probe seat 221 can be designed to be inconsistent. Specifically, the top surface of the first probe seat 211 can be higher than the top surface of the second probe seat 221. In this case, the first connecting part 321 can be connected to the top surface of the first probe seat 211, and the third connecting part 421 can be connected to the top surface or rear end surface of the second probe seat 221, thereby forming a height difference between the first connecting part 321 and the second connecting part 322.

[0104] The installation heights of the first probe seat 211 and the second probe seat 221 may also be designed to be consistent. By providing a pad at the connection between the first connection portion 321 and the top surface of the first probe seat 211 , a height difference may be formed between the first connection portion 321 and the second connection portion 322 .

[0105] When the installation heights of the first probe seat 211 and the second probe seat 221 are designed to be inconsistent, the top surface of the first probe seat 211 may be higher than the top surface of the second probe seat 221, and the bottom surface of the second probe seat 221 may be lower than the bottom surface of the first probe seat 211. In this case, the rear end surface of the first probe seat 211 is divided into an upper half and a lower half with the top surface of the second probe seat 221 as the boundary, and the rear end surface of the second probe seat 221 is divided into an upper half and a lower half with the bottom surface of the first probe seat 211 as the boundary. The first connecting portion 321 can be connected to the upper half of the rear end surface of the first probe seat 211, and the third connecting portion 421 can be connected to the lower half of the rear end surface of the second probe seat 221, so that the movement paths of the first probe seat 211 and the first connecting portion 321, and the movement paths of the second probe seat 221 and the third connecting portion 421 are completely staggered.

[0106] In the second example of the above embodiment, Figure 2 As shown, the first connecting portion 321 and the third connecting portion 421 can also be spaced apart in the front-to-back direction, that is, the first connecting portion 321 and the third connecting portion 421 can be staggered a certain distance in the front-to-back direction. This can be achieved by adjusting the shapes of the first connecting member 320 and the second connecting member 420 or the connection positions with the corresponding probe sets. For example, if the first connecting portion 321 is offset rearward relative to the third connecting portion 421, the first connecting member 320 and the second connecting member 420 will not overlap in space when retracting or extending.

[0107] Taking the case where the number of the first probe seat 211 and the second probe seat 221 are both 2 as an example, from left to right, they are arranged on the top of the mounting seat 100 as the first probe seat 211-second probe seat 221-first probe seat 211-second probe seat 221, that is, the second probe seat 221 on the left is located between the two first probe seats 211, and the first connecting part 321 needs to connect the two first probe seats 211, so there is a partial structure corresponding to the position of the second probe seat 221 on the left. By forming a groove with the partial structure corresponding to the first connecting part 321 and the second probe seat 221 on the left, there is a gap in the front-to-back direction with the partial structure connected to the second probe seat 221 on the left with the third connecting part 421. It is only necessary to ensure that the first probe seat 211 is in the first position. When the second probe seat 221 is in the second position, the structure of the third connecting part 421 connecting the second probe seat 221 on the left is still located in the groove.

[0108] The first example and the second example described above can be used alone or in combination according to the installation space conditions, thereby achieving a compact layout of the drive assembly in a limited space.

[0109] For example, the first probe seat 211 and the second probe seat 221 are installed on the same plane of the mounting seat 100, and the rear end face of the first probe seat 211 is located on the front side of the rear end of the first probe seat 211. In this case, the third connecting part 421 can adopt a straight structure, and the third connecting part 421 is connected to the rear end face of the second probe seat 221; the first connecting part 321 includes a cross bar and a connecting block protruding downward from the cross bar, and the connecting block is connected to the rear end face of the first probe seat 211 in a one-to-one correspondence. There is a gap between the connecting block and the third connecting part 421 along the front-to-back direction, and there is a gap between the cross bar and the third connecting part 421 along the up-down direction.

[0110] In other embodiments, the second probe seats 221 of the two second probe groups 222 can be designed as an integrated structure. Specifically, the two second probe groups 222 can also be arranged on the second probe seat 221 at intervals along the left and right directions, and the second probe seat 221 is slidingly connected to the mounting seat 100, and the two first probe seats 211 are slidingly connected to the second probe seat 221, one of the first probe seats 211 is located on the left side of the second probe group 222 on the left, and the other first probe seat 211 is located between the two second probe groups 222. This application does not limit this.

[0111] This application also proposes a second embodiment, such as Figures 3 to 8 As shown, the difference between the second embodiment and the first embodiment is that the third probe group 600 and the fourth probe group 700 can be adjusted to a certain extent to accommodate more terminals.

[0112] Specifically, if Figure 3 and Figure 4 As shown, the mounting base 100 includes a mounting platform 110, a support member 120 and an adjustment mechanism 130. The adjustment mechanism 130 and the support member 120 are both connected to the mounting platform 110. The third probe group 600 includes a plurality of third probes 600a. The plurality of third probes 600a are slidably connected to the support member 120 along the left-right direction, and the plurality of third probes 600a are spaced apart along the left-right direction. The third probe group 600 has a first state and a second state. The adjustment mechanism 130 is used to adjust the distance between some of the third probes 600a to switch the third probe group 600 to the first state or the second state.

[0113] like Figure 4 and Figure 5As shown, the fourth probe group 700 includes a switching mechanism 710, a first sub-probe group 720 and a second sub-probe group 730, the switching mechanism 710 has a first output end 711 and a second output end 712, the first output end 711 is connected to the first sub-probe group 720, and the second output end 712 is connected to the second sub-probe group 730; the first output end 711 is used to drive the first sub-probe group 720 to extend forward to the seventh position or retract backward to the eighth position, and the second output end 712 is used to drive the second sub-probe group 730 to extend forward to the ninth position or retract backward to the tenth position;

[0114] When the meter docking station 1000 is in the first mode, the second mode, or the third mode, the third probe group 600 is in the first state, the first sub-probe group 720 is at the seventh position, and the second sub-probe group 730 is at the tenth position;

[0115] The meter socket 1000 also has a fourth mode. When the meter socket 1000 is in the fourth mode, the third probe group 600 is in the second state, the first sub-probe group 720 is in the eighth position, the second sub-probe group 730 is in the ninth position, the first probe group 212 is in the second position, and the second probe group 222 is in the fourth position.

[0116] In this embodiment, the left-right spacing of the third probes 600a is adjusted by the adjustment mechanism 130, thereby defining two end positions according to the desired terminal to be connected. The two end positions correspond to the first state and the second state. The first sub-probe group 720 and the second sub-probe group 730 are not extended at the same time. The switching mechanism 710 switches to the first sub-probe group 720 extending or the second sub-probe group 730 extending. By combining different numbers and spacings of third probes 600a with the first sub-probe group 720 or the second sub-probe group 730, different types of terminals can be connected.

[0117] In the second embodiment, the first mode of the meter socket 1000 can be used to connect a small current load management terminal, the third mode of the meter socket 1000 can be used to connect a distribution transformer monitoring metering terminal and a concentrator, and the fourth mode of the meter socket 1000 can be used to connect a single-phase electric energy meter 3000.

[0118] like Figures 4 to 8As shown, the support member 120 may include two supporting side plates 121, which are arranged opposite to each other on the top of the mounting platform 110. The second probe seats 221 of the two second probe groups 222 can be connected into an integral body, that is, the left and right sides of the integral second probe seat 221 are slidably connected to the two supporting side plates 121, and the first probe seat 211 is slidably arranged on the top of the second probe seat 221. The first drive assembly 300 and the second drive assembly 400 are both installed on the mounting platform 110. The first probe assembly 210 and the second probe assembly 220 are mounted above the mounting platform 110 by the support member 120, and a certain gap is formed between the second probe seat 221 and the mounting platform 110, and the gap is used to install the third probe group 600 and the fourth probe group 700.

[0119] The supporting side plate 121 can have multiple slide grooves extending in the front-to-back direction, and the multiple slide grooves are arranged at intervals in the up-down direction. From bottom to top, the left and right sides of the first sub-probe group 720, the second sub-probe group 730 and the second probe group 222 can be slidably arranged in the corresponding slide grooves, so that when the corresponding driving structure is driven, the first sub-probe group 720, the second sub-probe group 730 and the second probe group 222 can maintain the stability of the upper and lower positions, reduce the height deviation when connected to the corresponding terminal, and improve the accuracy of the verification structure.

[0120] like Figure 7 As shown, the support member 120 further includes a plurality of guide rods 122 extending in a left-right direction. The ends of the guide rods 122 are connected to the two supporting side plates 121. The guide rods 122 may be cylindrical or prism-shaped, or some guide rods 122 may be cylindrical and the rest may be prism-shaped, which is not limited in this application. The surface of the third probe 600a is provided with grooves that match the guide rods 122, and the guide rods 122 guide the sliding direction of the second probe.

[0121] Furthermore, four guide rods 122 can be provided, wherein two guide rods 122 are located at the bottom of the third probe 600a to support and guide the second probe, and the other two guide rods 122 are located at the top of the third probe 600a to limit and guide the third probe 600a.

[0122] The adjustment method of the third probe 600a is described below.

[0123] like Figure 4 、 Figure 6 and Figure 7As shown, the third probe 600a includes a mounting block 610 and at least one probe body 620. The mounting block 610 refers to a sliding component that carries the probe body 620. The mounting block 610 is slidably connected to the support member 120 in the left-right direction, so that the mounting block 610 can move in the left-right direction, thereby changing the probe spacing. Specifically, the mounting block 610 is provided with a groove for cooperating with the guide rod 122 to guide the movement of the mounting block 610. The probe body 620 is connected to the mounting block 610, and the probe body 620 is at least exposed at the front end of the mounting block 610, which is convenient for connecting with the corresponding terminal. The mounting block 610 is also provided with a guide protrusion 611, which can be implemented by a cylindrical or rectangular protrusion.

[0124] The adjustment mechanism 130 includes a fourth drive member 131 and an adjustment plate 132. The adjustment plate 132 has a guide slot 1321, within which the guide protrusion 611 is positioned. The guide slot 1321 has an inclined or curved trajectory. The fourth drive member 131 linearly drives the guide protrusion 611 along the slot, driving the lateral movement of the mounting block 610. The fourth drive member 131 is a drive device that provides linear power and can be implemented using a cylinder, linear motor, or screw mechanism. The fourth drive member 131 is mounted on the mounting base 100, with its output end connected to the adjustment plate 132. The fourth drive member 131 drives the adjustment plate 132 in the forward and backward directions through telescopic movement.

[0125] The fourth driver 131 drives the adjustment plate 132 to move in the front-to-back direction. The interaction between the guide slots 1321 and the guide protrusions 611 converts the front-to-back movement of the adjustment plate 132 into left-to-right displacement of the mounting block 610. As the adjustment plate 132 moves, the guide protrusions 611 on different mounting blocks 610 move horizontally to varying degrees according to the trajectory of the guide slots 1321, thereby synchronously adjusting the distances between the multiple mounting blocks 610. Because the probe bodies 620 are fixed to the mounting blocks 610, the spacing between the probe bodies 620 is adjusted accordingly. For example, when adapting to a wider terminal interface, the adjustment plate 132 moves, causing the guide protrusions 611 to slide along the inclined guide slots 1321, driving the mounting blocks 610 outward and increasing the spacing between the probe bodies 620; otherwise, the spacing is reduced. This solution, through a single driver and mechanical linkage structure, enables the synchronous adjustment of multiple third probes 600a, eliminating the need for a separate drive mechanism for each third probe 600a, thereby improving adjustment accuracy and response speed.

[0126] The trajectory of the guide slot 1321 can be customized according to the interface size requirements of different types of terminals, further improving adaptation flexibility. For example, the guide slot 1321 can be designed as two sections, with a starting point, a turning point, and an end point, thereby providing three spacings for the probe body 620 to switch between, enabling the connection of more types of terminals. This is not limited in this application.

[0127] It should be noted that the number of probe bodies 620 required for different types of terminals is not the same. Taking the first mode for connecting a small current load management terminal and the fourth mode for connecting a single-phase electric energy meter 3000 as an example, the number of probe bodies 620 required for the small current load management terminal is 12, while the number of probe bodies 620 required for the single-phase ammeter 3000 is 4. Some probe bodies 620 can be retracted to avoid damage caused by collision between some probe bodies 620 and the single-phase ammeter 3000 when connecting to the single-phase ammeter 3000.

[0128] Or further, a meter socket 1000 can be connected to two small current load management terminals at the same time. In order to avoid excessive left and right movement of the probe body 620, the probe body 620 can be partially retracted, and an auxiliary probe can be added between the two groups of probe bodies 620 corresponding to the two small current load management terminals. The two groups of probe bodies 620 corresponding to the two small current load management terminals are redistributed to achieve the connection of three single-phase ammeters 3000, thereby further improving the calibration efficiency and improving the utilization rate of the third probe 600a.

[0129] like Figure 4 、 Figure 7 and Figure 8 As shown, the probe body 620 fixedly connected to the mounting block 610 is defined as a first probe body 621, and the probe body 620 slidably connected to the mounting block 610 is defined as a second probe body 622. Some mounting blocks 610 are only provided with the first probe body 621, while some mounting blocks 610 are provided with the first probe body 621 and the second probe body 622 at the same time. The third probe group 600 also includes a fifth driving member 910, one end of the fifth driving member 910 is connected to the mounting base 100, and the other end of the fifth driving member 910 is in transmission connection with the second probe body 622. The fifth driving member 910 is used to drive the second probe body 622 to extend forward to be flush with the first probe body 621, or to retract backward so that the first probe body 621 protrudes from the second probe body 622. That is, the number of extended probe bodies 620 can be changed through the fifth driving member 910. When the fifth driving member 910 drives the second probe body 622 to extend forward, the first probe body 621 and the second probe body 622 can be connected with the corresponding terminals at the same time. When the fifth driving member 910 drives the second probe body 622 to retract backward, only the first probe body 621 is connected with the corresponding terminal, and the second probe body 622 retracts to avoid it.

[0130] Specifically, the mounting block 610 has a through channel in the front-to-back direction, and the second probe body 622 can slide through the channel. The fifth driving member 910 drives the second probe body 622 to move in the channel to extend or retract the second probe body 622.

[0131] In some embodiments, the second probe body 622 has a transmission portion 6221, which is exposed from the mounting block 610. The fifth driving member 910 is connected to the transmission portion 6221 and is used to drive the transmission portion 6221 and drive the second probe body 622 to move in the front-to-back direction. The transmission portion 6221 can extend from the side of the mounting block 610, or it can extend from the rear end of the mounting block 610 and form a bent hook structure, which is not limited in this application.

[0132] The fifth driving member 910 can be consistent with the number of the second probe bodies 622 and connected one-to-one, so that the second driving member 410 can drive the corresponding second probe bodies 622 to move in the front-to-back direction. By driving the second probe bodies 622 of different positions or different numbers to retract, the total number and position of the probe bodies 620 in the extended state of the docking station 1000 can be adjusted.

[0133] Alternatively, multiple transmission parts 6221 may be connected to the same fifth driving member 910, so that the fifth driving member 910 can drive multiple second probe bodies 622 to move synchronously in the front-to-back direction. By replacing the individual driving scheme with a mechanical linkage scheme, the motion errors between multiple driving members are eliminated, while the number of driving members is reduced.

[0134] It should be noted that since the mounting block 610 needs to move left and right to adjust the spacing, the second probe body 622 will also move left and right accordingly. Therefore, the second probe body 622 and the fifth driving member 910 cannot be simply fixed and installed, but a transmission structure needs to be designed to absorb the displacement in the left and right directions.

[0135] In some embodiments, the transmission structure is designed with a transmission member 920 having a socket 921, so that the transmission part 6221 is inserted into the socket 921. When the fifth driving member 910 drives the transmission member 920 to move in the front and rear directions, the transmission part 6221 can move in the left and right directions in the socket 921, thereby absorbing the displacement of the second probe body 622 in the left and right directions driven by the mounting block 610.

[0136] Based on mechanical linkage scheme, such as Figure 8As shown, a long strip socket 921 extending in the left-right direction can be designed on a transmission plate, by inserting the transmission parts 6221 of multiple second probe bodies 622 into the same long strip socket 921; or a plurality of sockets 921 spaced apart in the left-right direction can be set according to the left-right movement trajectory of the second probe body 622, and multiple second probe bodies 622 with overlapping parts in the left-right movement trajectory can be inserted into the same socket 921, so that a fifth driving member 910 can synchronously drive the multiple second probe bodies 622 to extend or retract.

[0137] The transmission member 920 can be mounted on the mounting platform 110 via a linear guide rail, thereby guiding the movement of the transmission member 920 and facilitating the synchronous retraction of the second probe body 622 .

[0138] The above-mentioned distribution transformer monitoring and metering terminal, concentrator, and small current load management terminal are collectively referred to as the small current terminal 2000. The following describes how to switch to different modes and connect to the single-phase electric energy meter 3000 or different types of small current terminals 2000 in the second embodiment.

[0139] For the third probe set 600:

[0140] like Figure 9 and Figure 10 The arrangement of the high-voltage wiring terminals of the small current terminal 2000 is the same, and the height difference between the high-voltage wiring terminals of the small current terminal table and the single-phase energy meter 3000 is 0.3mm. Figure 6 and Figure 8 As shown, the third probe set 600 is compatible with two types of electric energy meters in the vertical direction, so it is only necessary to adjust the horizontal spacing of the probe bodies 620 in the third probe set 600 to corresponding positions.

[0141] Number each high-current terminal of the low-current terminal 2000, such as Figure 9 As shown in the figure, the current columns are a1, a2, a3, a4, a5, a6, a7, and a8, and the voltage columns are b1, b2, b3, and b4. The high-voltage terminals of the single-phase energy meter 3000 are numbered as follows: Figure 10 As shown, they are A1, A2, A3, and A4. By comparing the number of high-voltage terminals of the low-current terminal 2000 and the single-phase energy meter 3000, we can see that the low-current terminal 2000 has more high-voltage terminals and the single-phase energy meter 3000 has fewer high-voltage terminals. Therefore, the position of the high-voltage terminals of the low-current terminal 2000 is used as a reference, as shown in FIG. Figure 11 As shown, the probe bodies 620 are grouped and seven third probes 600a are designed, namely K1 to K7. Among them, the third probes 600a numbered K1, K4, and K7 only have the first probe body 621, and the third probes 600a numbered K2, K3, K5, and K6 have the first probe body 621 and the second probe body 622.

[0142] For the numbering of high-voltage wiring terminals, see Figure 9 and Figure 10 , the number of the third probe 600a is shown in Figure 11 , see the structure of the terminal block Figures 4 to 8 .

[0143] As previously discussed, a single meter socket 1000 can simultaneously calibrate two low-current terminals 2000 or three single-phase energy meters 3000. When calibrating a single-phase energy meter 3000, the high-current terminals A1, A2, A3, and A4 of the first single-phase energy meter 3000 are moved left and right by the third probe 600a corresponding to the high-current terminals of the first low-current terminal 2000, specifically numbered K1, K2, K3, and K4. The high-current terminals A1, A2, A3, and A4 of the second single-phase energy meter 3000 are moved left and right by the third probe 600a corresponding to the first low-current terminal 2000, numbered K7, two auxiliary probes J1 and J2, and the third probe 600a corresponding to the second low-current terminal 2000, numbered K1, and then docked. The strong current connection terminals A1, A2, A3, and A4 of the third single-phase electric energy meter 3000 are respectively connected by the third probe 600a corresponding to the second low-current terminal 2000 after being moved left and right, and are specifically numbered K4, K5, K6, and K7.

[0144] When calibrating a single-phase electricity meter 3000, all second probe bodies 622 need to be pulled back to avoid collision with the single-phase electricity meter 3000. The pulled back second probe bodies 622 correspond to the high-voltage terminals b1, b2, a5, b3, a6, and b4 of the first low-current terminal 2000, and the high-voltage terminals b1, a2, a3, b2, b3, and b4 of the second low-current terminal 2000. The horizontal translation of the third probe 600a is driven by the fourth drive member 131. The guide protrusion 611 on the mounting block 610 moves within the guide groove 1321 on the adjustment plate 132 through the adjustment plate 132, driving the left and right translation of the third probe 600a. The second probe body 622 is driven backward by the fifth drive member 910 to drive the transmission member 920, which drives the second probe body 622 backward through the transmission portion 6221.

[0145] For the fourth probe set 700:

[0146] When testing the low-current terminal 2000, the second output end 712 of the switching mechanism 710 drives the second sub-probe group 730 to retract to the tenth position, while the first output end 711 drives the first sub-probe group 720 to extend to the seventh position.
