[0046] As Figure 1 shown, the electricity meter detection device 100 includes a probe structure 110 and a buckle structure 120. The probe structure 110 can abut against the terminals of the electricity meter, and the buckle structure 120 is used to buckle the inherent card slot of the electricity meter. The electricity meter detection device 100 can detect the faults and operation errors of the electricity meter. However, the above-mentioned electricity meter detection device is only applicable to electricity meters of specific sizes and is difficult to meet the detection requirements of different models of electricity meters.

[0047] As Figure 2 shown, an embodiment of the present application provides a wiring base (hereinafter referred to as the wiring base) 200 for an electricity meter detection device. The wiring base 200 includes: a housing 1, a fixing structure 2, a positioning structure 3, a plurality of probe contacts 4, and a wiring terminal 5.

[0048] The housing 1 is used to support other components of the wiring base 200. Optionally, the inside of the housing 1 is a cavity.

[0049] As Figure 3 shown, the fixing structure 2 is arranged on the housing 1, and the fixing structure 2 can be detachably connected to the electricity meter detection device 100. For example, the fixing structure 2 is arranged on the top surface of the housing 1. The fixing structure 2 includes a protrusion 21, and a clamping structure adapted to the buckle structure 120 is arranged on the side wall of the protrusion 21. Optionally, the fixing structure 2 and the housing 1 are integrally formed by injection molding.

[0050] The positioning structure 3 is arranged on the housing 1. When connecting the electricity meter detection device 100, the positioning structure 3 is used to position the electricity meter detection device 100. Optionally, the positioning structure 3 and the housing 1 are integrally formed by injection molding. For example, the positioning structure 3 can abut against the electricity meter detection device 100 to position the connection between the electricity meter detection device 100 and the wiring base 200.

[0051] A plurality of probe contacts 4 are arranged on the top surface of the housing 1, and the plurality of probe contacts 4 can abut against the probes of the electricity meter detection device 100. The number and positions of the probe contacts 4 are adapted to the probe structure 110 of the electricity meter detection device 100, and each probe contact 4 corresponds to a probe. The probe contacts 4 can be selected from existing probe contacts.

[0052] As Figure 4 shown, optionally, a circuit board 6 is arranged in the cavity of the housing 1, and the plurality of probe contacts 4 are all electrically connected to the circuit board 6.

[0053] The terminal 5 is arranged on the housing 1, and the terminal 5 is electrically connected to the probe contact 4. For example, the terminal 5 is electrically connected to the circuit board 6 to achieve the electrical connection between the terminal 5 and the probe contact 4. The end of the terminal 5 can be connected to the electricity meter. For example, a power connection clip is arranged at the end of the terminal 5, and the power connection clip can be connected to the terminal of the electricity meter.

[0054] In this embodiment, the electricity meter detection device 100 is arranged on the wiring base 200. The probe of the electricity meter detection device 100 abuts against the probe contact 4. The end of the terminal 5 is connected to the terminal of the electricity meter. The terminal 5 transmits the detection signal to the electricity meter detection device 100 through the probe contact 4 to detect the electricity meter. The terminal 5 can be connected to various models of electricity meters, which is convenient for the electricity meter detection device 100 to detect different models of electricity meters.

[0055] As Figure 5 shown, in some embodiments, the terminal 5 includes a first terminal 51, a second terminal 52, and a detection line 53. The first terminal 51 is arranged on the housing 1, and the bottom end of the first terminal 51 is electrically connected to the circuit board 6. The second terminal 52 can be partially inserted into the first terminal 51 to be detachably connected to the first terminal 51. One end of the detection line 53 is connected to the second terminal 52, and the other end of the detection line 53 is connected to the connection clip so that the detection line 53 can be connected to the terminal of the electricity meter. After the second terminal 52 is connected to the first terminal 51, it usually does not need to be disassembled. When using the wiring base 200, just connect the connection clip to the terminal of the electricity meter. This structural design not only greatly simplifies the wiring process, reduces wiring errors and adjustment time, improves work efficiency, but also avoids potential safety hazards such as electric sparks and wiring errors in the traditional wiring method.

[0056] As Figure 6 shown, in some embodiments, the fixing structure 2 includes a card slot 22. For example, protrusions 21 are arranged on both sides of the top surface of the housing 1, and card slots 22 are arranged on the side walls of the two protrusions 21. The buckle structure 120 of the electricity meter detection device 100 includes a hook, and the card slot 22 is adapted to the hook of the electricity meter detection device 100.

[0057] As Figure 7 and Figure 8 shown, in some embodiments, the positioning structure 3 includes at least two positioning posts 31 and a positioning piece 32.

[0058] At least two positioning posts 31 are respectively arranged on both sides of the housing 1. For example, the number of positioning posts 31 is two, and the two positioning posts 31 are respectively arranged on both sides of the housing 1. Optionally, the positioning posts 31 are integrally formed with the housing 1.

[0059] The interior of the housing 130 of the electricity meter detection device 100 is a cavity, and the positioning posts 31 can enter the cavity of the electricity meter detection device 100. The two positioning posts 31 respectively abut against the inner side walls of the electricity meter detection device 100 to limit the left - right direction of the electricity meter detection device 100.

[0060] The positioning pieces 32 are arranged on the side walls of the positioning posts 31. Optionally, the positioning pieces 32 are located on the rear side walls of the positioning posts 31. The number of the positioning pieces 32 is two, and one positioning piece 32 is arranged on each positioning post 31. A gap 33 is formed between the positioning pieces 32 and the positioning posts 31, and the flanging of the housing 130 of the electricity meter detection device 100 can be inserted into the gap 33 to limit the front - rear direction of the electricity meter detection device 100.

[0061] The electricity meter detection device 100 is limited by the positioning posts 31 and the positioning pieces 32, which improves the connection accuracy between the electricity meter detection device 100 and the wiring base 200.

[0062] As Figure 9 shown, in some embodiments, the horizontal cross - sectional area of the positioning post 31 gradually decreases from bottom to top. Optionally, the positioning post 31 is generally in the shape of a square pyramid. Since the horizontal cross - sectional area of the positioning post 31 gradually decreases from bottom to top, when the electricity meter detection device 100 is connected to the wiring base 200, the top end of the positioning post 31 first enters the cavity of the electricity meter detection device 100, which is convenient for guiding the installation of the electricity meter detection device 100. According to needs, the positioning post 31 can also be set to have a constant horizontal cross - sectional area from bottom to top.

[0063] As Figure 10 shown, in some embodiments, the positioning piece 32 includes a connecting portion 321 and a positioning portion 322. One end of the connecting portion 321 is connected to the side wall of the positioning post 31, and the connecting portion 321 extends substantially along the front - rear direction of the wiring base 200. The positioning portion 322 is connected to the other end of the connecting portion 321, and the positioning portion 322 extends substantially outward along the left - right direction of the wiring base 200. A gap 33 is formed between the positioning portion 322 and the positioning post 31.

[0064] As Figure 4 shown, in some embodiments, the electricity meter detection device 100 is applicable to detecting three - phase electricity meters. The wiring terminals 5 include: voltage wiring terminals 54, pulse wiring terminals 55, and communication wiring terminals 56. The voltage wiring terminals 54 are used to detect the voltage signals entering the electricity meter. The pulse wiring terminals 55 are used for the input and output of electricity pulse signals. The communication wiring terminals 56 are used to connect the auxiliary wiring terminals of the electricity meter, establish communication with the electricity meter in the RS485 mode, and perform data transmission.

[0065] When detecting the electric energy meter to be tested, the pulse connection terminal 55 is used to receive the pulse signal generated by the electric energy meter. The pulse connection terminal 55 can be directly connected to the auxiliary connection terminal of the electric energy meter to be tested through a power connection clip, or can be connected to an optical sampling device to collect the optical pulse signal of the electric energy meter to be tested.

[0066] When the electric energy meter detection device 100 is used as a device to be sent for inspection, the pulse connection terminal 55 is used to output the pulse signal generated by the electric energy meter detection device 100. Therefore, the present application also considers the inspection link of the electric energy meter detection device 100, so that the test signal can be quickly and accurately connected during the inspection process, improving the smoothness and efficiency of the test process.

[0067] As Figure 11 shown, in some embodiments, the housing 1 includes a housing body 11 and a flange 12. The flange 12 is provided at the bottom end of the outer wall of the housing body 11. The housing body 11 and the flange 12 form a stepped structure. The housing body 11 can enter the housing 130 of the electric energy meter detection device 100. When the electric energy meter detection device 100 is connected to the connection base 200, the flange 12 can abut against the bottom surface of the electric energy meter detection device 100 to limit the further descent of the electric energy meter detection device 100. At the same time, the stepped structure prevents the electric energy meter detection device 100 from tilting. Optionally, the flange 12 is located on the front end face, left side wall and right side wall of the housing body 11.

[0068] As Figure 12 shown, the electric energy meter detection device 300 is suitable for detecting single-phase electric energy meters. The electric energy meter detection device 300 includes a guide post 310 and a hook 320. The probe contacts 4 and the connection terminals 5 of the connection base 200 are adapted to the electric energy meter detection device 300. The positioning structure 3 includes a positioning groove 34, and the positioning groove 34 is provided on the top surface of the housing 1. The positioning groove 34 is adapted to the guide post 310, and the guide post 310 is inserted into the positioning groove 34 to position the electric energy meter detection device 300. A clamping hole 23 is provided on the groove wall of the positioning groove 34, and the clamping hole 23 is adapted to the hook 320.

[0069] In some embodiments, the connection base 200 further includes a conductive post 7, and the conductive post 7 is electrically connected to the circuit board 6 to conduct the conductive post 7 and the pulse connection terminal 55. The conductive post 7 can be inserted into the electric energy meter detection device, and the conductive post 7 is electrically connected to the power supply circuit of the electric energy meter detection device to supply power to the pulse connection terminal 55. Further, when the pulse connection terminal 55 is connected to the optical sampling device, it supplies power to the optical sampling device.

[0070] As Figure 13As shown in the figure, an embodiment of the present application provides a watt-hour meter detection component, which includes the wiring base 200 and the watt-hour meter detection device 400 as described above. The watt-hour meter detection device 400 can be the watt-hour meter detection device 100 applicable to three-phase watt-hour meters or the watt-hour meter detection device 300 applicable to single-phase watt-hour meters. The watt-hour meter detection device 400 is installed on the wiring base 200 to expand the applicable range of the watt-hour meter detection device 400.
