[0002] In the traditional single-phase electric energy meter calibration process, the voltage of the on-site calibrator is connected to the screw of the electric energy meter terminal through the voltage wire clamp, the pulse line is also connected to the pulse port of the electric energy meter through the wire clamp, and then the current clamp is connected to the incoming line of the electric energy meter to perform on-site calibration of the electric energy meter. Because the contact area between the wire clamp of the single-phase electric energy meter field calibrator and the electric energy meter terminal post is small, the wiring often falls off, and the staff needs to repeatedly perform live wiring. Usually, the screws on the electric energy meter terminal post head are backed out 3-4 threads so that the voltage line does not fall off. In this way, sometimes the staff forgets to tighten the backed screws, resulting in loose wiring of the electric energy meter. After retrieval, the patent with application number CN201721541395.1 discloses an integrated wiring device for an electric energy meter field calibrator, wherein the fixed bracket is provided with an opening for a fastener to pass through the opening to fix the fixed bracket to the electric energy meter; the mobile bracket includes a base and a side frame, both sides of the base are connected with side frames that can be hung on the fixed bracket, and the base is provided with multiple ejectors, and the ejectors are all provided with leads.

DETAILED DESCRIPTION

[0039] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0040] Embodiment 1

[0041] In order to quickly, safely and firmly connect the field calibrator to the energy meter, Figure 1-Figure 4 An embodiment of the present invention can quickly fix the wiring device on the electric energy meter and dock with the terminal of the electric energy meter to prevent the wiring from falling off the electric energy meter, thereby reducing the time wasted by repeated wiring. A wiring device for a one-way electric energy meter field tester includes an insulating resin body 1, the insulating resin body 1 includes a base 101 and two side columns 102 that wrap the electric energy meter from two sides respectively, the base 101 and the side columns 102 are integrally cast by insulating resin, one side of the insulating resin body 1 is provided with a plurality of limiting holes 3 corresponding to the terminal of the electric energy meter, the limiting hole 3 is provided with a spring probe 4 with both ends extending to the outside thereof, one end of the spring probe 4 is connected to a plug 5, when in use The size of the insulating resin block is designed according to the size of the electric energy meter, so that the insulating resin body 1 can wrap the electric energy meter from three sides after it is close to the electric energy meter, so that the insulating resin body 1 is stuck on the electric energy meter, and the insulating resin body 1 and the electric energy meter are fixed. In this process, the spring probe 4 gradually approaches the electric energy meter and is finally pressed on the terminal of the electric energy meter. The terminal of the electric energy meter is led out with the spring probe 4, and then according to the needs of the detection, the spring probe 4 is connected to the calibrator with the plug 5 respectively, and the pulse and voltage of the electric energy meter are detected. At the same time, a load is provided to the electric energy meter, which can quickly and safely complete the wiring of the single-phase electric energy meter field calibrator, and at the same time meet the needs of the electric energy meter to connect to the load when needed.

[0042] In order to connect the probe to the power meter terminals with different protruding lengths, refer to Figure 2 and Figure 3The spring probe 4 includes a longitudinal rod 41 with one end extending to the inside of the limiting hole 3, the top of the longitudinal rod 41 is connected to a longitudinal tube 42, the top of the longitudinal tube 42 is provided with a voltage contact 43 with one end movably extending to the inside thereof, the end of the voltage contact 43 away from the longitudinal tube 42 is spherical, and the inside of the longitudinal tube 42 is provided with an adjustment component 44 for adjusting the position of the voltage contact 43, the adjustment component 44 includes a spring 441 movably arranged inside the longitudinal tube 42, a steel ball 442 is slidably connected to the bottom of the spring 441, the inner wall of the longitudinal tube 42 is provided with an internal thread groove, the top of the longitudinal rod 41 is fixedly connected with a threaded rod 443 adapted to the internal thread groove, one end of the threaded rod 443 movably extends to the inside of the longitudinal tube 42, and when in use, the spring A 441 pushes the voltage contact 43 to move away from the longitudinal rod 41, so that the voltage contact 43 moves to the position farthest from the insulating resin body 1, and then moves the insulating resin body 1 gradually close to the electric energy meter until the insulating resin body 1 is stuck on the electric energy meter. In this process, the spring probe 4 contacts the terminal and is then squeezed. After being squeezed, the voltage contact 43 moves toward the inside of the longitudinal tube 42, squeezing and contracting the spring 441 until the insulating resin body 1 is firmly fixed on the electric energy meter, so that the probe has good elasticity and can well adapt to the different lengths of the nut left outside the terminal post due to the different thicknesses of the electric energy meter's input and output lines, so that the probe can form good contact with the terminal of the electric energy meter in different conditions.

[0043] Since the distance that the voltage contact 43 can be extended is affected by the spring 1 441, and the firmness of the voltage contact 43 in contact with the terminal of the electric energy meter is also affected by the elastic force of the spring 1 441, in order to adjust the distance that the voltage contact 43 can be extended and the force of pressing the terminal, the number of steel balls 442 installed in the longitudinal tube 42 can be selected in this embodiment. When it is necessary to extend the voltage contact 43 to a longer distance and ensure that the voltage contact 43 is firmly connected to the terminal, the longitudinal tube 42 can be rotated until the longitudinal tube 42 is separated from the threaded rod 1 443, and then the steel balls 442 inserted into the longitudinal tube 42 are increased. The number of steel balls 442 is then reinstalled on the threaded rod 443. At this time, the increased number of steel balls 442 inside the longitudinal tube 42 pushes the spring 441 to move in the direction of the voltage contact 43, so that the spring 441 can push the voltage contact 43 to move a longer distance. In addition, the steel balls 442 increase the elastic force of the spring 441 on the voltage contact 43 by squeezing the spring 441, so that the extension distance of the voltage contact 43 and the force of pressing the terminal can be adjusted according to needs, which facilitates the adjustment of the voltage contact 43 to contact with terminals of different lengths and can also improve the firmness of the connection between the voltage contact 43 and the terminal.

[0044] In order to better connect the different connectors of the field calibrator after being led out through the spring probe 4, the plug 5 includes male and female plugs 51 and an integrated female plug 52 which are respectively connected to different spring probes 4. A connector corresponding to the female plug of the male and female plugs 51 is provided at the bottom of the spring probe 4. The integrated female plug 52 is connected to the male plug of the male and female plugs 51. When in use, the male plug or female plug of the male and female plug 51 can be connected to the spring probe 4, and then the other end of the male and female plug 51 can be connected to the field calibrator, or connected to the load through the integrated female plug 52.

[0045] In order to fix the wiring device and the electric energy meter more firmly, refer to Figure 1 and Figure 2 A boss 2 is provided on the side opposite to the side column 102, and a stress release groove 6 is provided on the side of the side column 102 away from the base 101. When in use, the electric energy meter is inserted between the two side columns 102. In this process, the boss 2 is squeezed and deformed, so that the electric energy meter is more firmly fixed on the insulating resin body 1. When the boss 2 is squeezed, the boss 2 can move toward the stress release groove 6 after deformation, and at the same time drive the side column 102 to move into the stress release groove 6 after deformation. The boss 2 can be used to reduce the gap between the electric energy meter and the insulating resin body 1, so that the connection between the wiring device and the electric energy meter is more firmly. At the same time, space is reserved to accommodate the boss 2 and the side column 102 that are squeezed and deformed, so as to prevent the boss 2 and the side column 102 from being squeezed and damaged by the electric energy meter.

[0046] Embodiment 2

[0047] In order to adjust the position of the spring probe 4, so that the spring probe 4 can be connected with the terminal of different specifications of electric energy meters, and adapt to the wiring work of more types of electric energy meters, refer to Figure 1-Figure 5 On the basis of the first embodiment, a slide groove penetrating the base 101 is provided on one side of the base 101, and two limit frames 7 are provided in the slide groove. A rubber block 8 corresponding to the limit hole 3 is slidably connected inside the limit frame 7, and the limit hole 3 penetrates the rubber block 8. When in use, the rubber block 8 is slid along the slide groove, thereby driving the limit hole 3 and the spring probe 4 inserted therein to move along the width direction of the insulating resin body 1 until the spring probe 4 is aligned with the terminal of the electric energy meter. The position of the spring probe 4 can be flexibly adjusted along the width direction of the insulating resin body 1, so that the spring probe 4 can be docked with the terminal of electric energy meters of different specifications, thereby improving the adaptability of the wiring device to electric energy meters of different specifications.

[0048] Embodiment 3

[0049] In order to facilitate fixing the spring probe 4 after adjusting its position, and prevent the spring probe 4 from shaking and causing a loose connection with the terminal, refer to Figure 1-Figure 6On the basis of the first embodiment, both ends of the limit frame 7 are slidably connected to the inner wall of the slide slot, and a clamping assembly 9 for fixing the position of the limit frame 7 is provided inside the slide slot. The clamping assembly 9 includes a threaded rod 91 with both ends fixedly connected to the inner wall of the slide slot, a through hole corresponding to the threaded rod 91 is provided on one side of the limit frame 7, and nuts 92 sleeved on the outside of the threaded rod 91 are provided on both sides of the limit frame 7. One side of the limit frame 7 is open, and an extrusion plate 10 covering the opening is slidably connected between the two sides of the inner wall of the limit frame 7. A plurality of rubber pads 11 are fixedly connected to the side of the extrusion plate 10 close to the rubber block 8. When in use, the limit frame 7 is first moved along the width direction of the insulating resin body 1, so that the rubber block 8 and the spring probe 4 are in contact with the rubber block 8. The terminals are in the same row, and then the extrusion plate 10 is moved away from the rubber block 8, and then the rubber block 8 is moved along the length direction of the limit frame 7, so that the spring probe 4 on the rubber block 8 is completely aligned with the position of the terminal of the electric energy meter, and then the extrusion plate 10 is pushed close to the rubber block 8, and the rubber pad 11 squeezes the rubber block 8 to fix the position of the rubber block 8, and then the nut 92 is rotated, and the nut 92 moves along the threaded rod 91, and squeezes the limit frame 7 and the extrusion plate 10 from both sides of the limit frame 7 respectively, and fixes the position of the limit frame 7, the rubber block 8 and the spring probe 4, so as to facilitate the adjustment of the position of the spring probe 4 in different directions, so that the spring probe 4 is aligned with the terminal of the electric energy meter, and at the same time, it is convenient to fix the spring probe 4 after the position is adjusted.

[0050] Embodiment 4

[0051] Since the protrusion 2 is constantly squeezed by the electric energy meter during use, it is easy to wear and break. After the protrusion 2 is worn, its width is reduced, and the clamping effect on the electric energy meter is reduced, which easily causes a gap between the electric energy meter and the insulating resin body 1. Figure 1-Figure 9 On the basis of the first embodiment, in order to maintain the squeezing effect of the convex column 2 on the electric energy meter, two circular grooves penetrating the side column 102 are provided on the top of the base 101, and the bottom of the inner side of the circular groove is fixedly connected with a bottom plate 12, and the top of the bottom plate 12 is provided with a longitudinal plate 13 with one end extending to the outside of the base 101, and the top of the longitudinal plate 13 is fixedly connected with a top plate 14, and a lifting plate 15 is slidably connected to one side of the longitudinal plate 13, and a spring 16 is fixedly connected between the bottom plate 12 and the lifting plate 15, and the convex column 2 is installed between the lifting plate 15 and the top plate 14, and one end of the convex column 2 is movably extended to the base 1 01 Inside, a plurality of anti-skid pads 17 are fixedly connected to the bottom of the top plate 14. When in use, the bottom of the boss 2 is placed on the lifting plate 15, and then the boss 2 is pressed downward to drive the lifting plate 15 to descend, and at the same time, the spring 2 16 is squeezed and contracted, and then the top of the boss 2 is moved to the bottom of the top plate 14, and the boss 2 is released. The spring 2 16 pushes the lifting plate 15 and the boss 2 to rise until the top of the boss 2 is pressed against the top plate 14. The top of the boss 2 is difficult to fall off from the top plate 14 due to the anti-skid pad 17. When the insulating resin body 1 is stuck on the electric energy meter, the electric energy meter squeezes and deforms the boss 2.

[0052] When the boss 2 is worn or cracked and affects its use, it is only necessary to remove the boss 2 from between the top plate 14 and the lifting plate 15, and then replace it with a new boss 2. This facilitates the replacement of the boss 2 and reduces the influence of the boss 2 on the connection firmness between the wiring device and the electric energy meter after wear and tear, ensuring that the wiring device can still be firmly installed on the electric energy meter after long-term use.

Apply a pulling force of 10N at the connection to test whether the connection is disconnected and count the connection time. Step 3: Detect the voltage. After the voltage and current of the electric energy meter are drawn out through the spring probe (4), they are connected to the male plug of the male and female plugs (51), and then connected to the calibrator through the female plugs of the male and female plugs (51). A fixed time is measured, the weight of the calibrator line is simulated, a pulling force of 20N is applied, and the number of times the connector is disconnected is counted; Step 4: Provide a load, lead out the live wire and the neutral wire of the electric energy meter with a spring probe (4), connect them to the female plug of the male and female plug (51), then connect the male plug to the integrated female plug (52), connect to the load through the integrated female plug (52), count the connection time, and then apply a pulling force of 10N to test whether the connection is disconnected.
