[0045] The lifting assembly 4 is disposed on one side of the housing 1 in the first direction X. The lifting assembly 4 includes a lifting frame 41 and a position adjusting portion 42. The lifting frame 41 is connected to the housing 1 through the position adjusting portion 42. The housing 1 can slide along the third direction Z relative to the lifting frame 41. The position adjusting portion 42 is used to adjust the relative position relationship between the lifting frame 41 and the housing 1.

[0046] The first direction X and the third direction Z are perpendicular to each other.

[0047] Based on the above technical solution, multiple wiring devices are arranged at intervals along the first direction X, and the lower end of the wiring assembly 3 can be detachably installed on the bottom of the shell 1. According to the number and position of the wiring terminals of the electric energy meter, multiple wiring assemblies 3 can be disassembled and assembled, so that the number and position of the wiring assemblies 3 match the wiring terminals of the electric energy meter. The wiring operation between the electric energy meter and the wiring device can be completed by directly matching and plugging the conductive part of the wiring assembly 3 with the wiring terminals of the electric energy meter, and the operation is convenient and fast; a lifting assembly 4 is set, and the adjustment part 42 can adjust the relative position relationship between the lifting frame 41 and the shell 1.

[0048] Preferably, if Figure 3 , 7 As shown in , 8, the wiring assembly 3 includes a conducting column 31, a conducting column 32, a limiting nut 33 and a first spring 34.

The upper end surface of the limiting nut 33 abuts against the bottom surface of the end cover 2. The first spring 34 is sleeved on the outer periphery of the conducting column 32. The upper end of the first spring 34 is connected to the limiting nut 33. The lower end of the first spring 34 is connected to the bottom of the shell 1. The conducting column 31 and the conducting column 32 are detachably connected through the engagement of the second stud 311 and the threaded hole 322.

The conducting column 31 and the terminal block ensure stable contact and conduction under stable pressure. The first spring 34 allows the conducting column 31 to slide in the up and down directions, which can adapt to the different depths of the terminal blocks of different electric energy meters.

[0049] More preferably, if Figure 5As shown, a plurality of through holes 12 and a plurality of positioning holes 13 are provided at the bottom of the shell 1, and the plurality of through holes 12 are arranged at intervals along the first direction X, and the plurality of through holes 12 correspond to the plurality of wiring components 3 one by one, and the positioning holes 13 are located on one side of the through holes 12, and the lower ends of the conductive columns 32 are correspondingly penetrated in the through holes 12 one by one, and the lower ends of the conductive columns 32 are provided with third studs 323, and the upper ends of the third studs 323 are fixedly sleeved with a limiting plate 35, and the upper end surface of the limiting plate 35 is provided with a positioning column 351, and the positioning column 351 is plugged with the positioning hole 13, and the upper end surface of the limiting plate 35 is abutted against the bottom surface of the shell 1, and a wire clamping nut 36 is provided below the limiting plate 35, and the wire clamping nut 36 is meshed with the third stud 323. A third stud 323 is provided at the lower end of the conductive column 32, on which a limiting plate 35 is fixed and a wire clamping nut 36 is screwed. When the wiring device needs to be connected to an external line, the wires of the external line are wound around the third stud 323, and the wire clamping nut 36 is screwed. The wire clamping nut 36 and the limiting plate 35 clamp the wires together, so that the wires are fastened to the third nut, and the wiring is convenient and reliable; a positioning column 351 is provided at the upper end of the limiting plate 35, and the positioning column 351 is plugged in and matched with the positioning hole 13 of the shell 1, which can prevent the conductive column 32 from rotating when docking with the electric energy meter, and can provide a correcting force for the installation and removal of the limiting nut 33. When the limiting nut 33 is screwed in or removed from the first stud 321, the conductive column 32 will not rotate with the rotation of the limiting nut 33, thereby increasing the stability and convenience of installation and removal.

[0050] More preferably, if Figure 4As shown, the wiring assembly 3 also includes a locking portion 37, a plurality of through slots 21 are provided on the end cover 2, and the plurality of through slots 21 are arranged at intervals along the first direction X, the through slots 21 are located at the rear side of the conducting column 31, and a positioning slot 312 extending along the third direction Z is provided on the conducting column 31, and the positioning slot 312 faces the through slot 21, and the locking portion 37 includes a stop 371, a second spring 372, a first slider 373 and a positioning block 374, the stop 371 is provided at the bottom of the end cover 2, and the first slider 373 is partially accommodated in the through slot 21, the first slider 373 can slide along the first direction X, the upper end of the first slider 373 is fixedly connected to the positioning block 374, the two ends of the second spring 372 are respectively arranged on the first slider 373 and the support 371, and the positioning block 374 has a locking position and an unlocking position on its sliding path. When the positioning block 374 is located at the locking position, the positioning block 374 is partially accommodated in the positioning groove 312; when the positioning block 374 is located at the unlocking position, the positioning block 374 is not accommodated in the positioning groove 312. When the first slider 373 slides toward the stop seat 371, the first slider 373 overcomes the elastic force of the second spring 372 to slide, and the positioning block 374 slides with the first slider 373 from the locked position to the unlocked position, and the positioning block 374 slides out of the positioning slot 312. At this time, the conductive column 31 is free from the restriction of the positioning block 374, and the conductive column 31 can be screwed out, which is convenient for replacing the conductive column 31; when the first slider 373 slides away from the stop seat 371, the elastic force of the second spring 372 drives the first slider 373 to slide, and the positioning block 374 slides with the first slider 373 from the unlocked position to the locked position, and the positioning block 374 is partially inserted into the positioning slot 312 to limit the rotation of the conductive column 31.

[0051] In a specific embodiment, the length of the positioning groove 312 is smaller than the length of the positioning column 351. When the conductive column 31 slides downward under pressure, the conductive column 32 slides downward at the same time. When the conductive column 31 slides to the positioning block 374 and abuts against the upper end groove wall of the positioning groove 312, the positioning column 351 will not fall out of the positioning hole 13, ensuring that the lower end of the conductive column 32 can slide stably and the sliding is more stable.

The synchronous handle 5 is slidably arranged on the outer edge of the end cover 2, and the two ends of the transmission member 38 are respectively arranged on the first slider 373 and the synchronous handle 5. When the synchronous handle 5 is pulled, the first slider 373 overcomes the elastic force of the second spring 372 and slides backward, and the positioning block 374 disengages from the positioning groove 312. When the synchronous handle 5 is released, the second spring 372 drives the first slider 373 to slide forward, and the positioning block 374 is partially inserted into the positioning groove 312.

[0054] Specifically, the transmission member 38 is a pull wire, and a plurality of threading holes are provided on the end cover 2. The two ends of the pull wire are respectively connected to the synchronous handle 5 and the first slider 373. The synchronous handle 5 is connected to all the pull wires. When the synchronous handle 5 is pulled, all the pull wires slide along their corresponding threading holes, pulling all the first sliders 373 to slide in the direction of the stop seat 371, and all the positioning blocks 374 are simultaneously disengaged from their corresponding positioning grooves 312.

[0055] More preferably, if Figure 1 , 2 As shown, the wiring device also includes a gusset plate 6, which is arranged on the upper end surface of the end cover 2.

[0056] The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0057] The cooperation and insertion of the limiting column 63 and the limiting groove 3741 can prevent the positioning block 374 from swinging when the first slider 373 is pulled by the pull wire and pushed by the second spring 372, thereby ensuring the consistency and stability of the sliding of the positioning block 374, thereby achieving stable restriction of the conducting column 31 by the positioning block 374.

At this time, the lifting frame 41 is moved, and after the relative position relationship between the shell 1 and the lifting frame 41 is determined, the push plate 421 is released, and the push plate 421 is reset under the elastic force of the fourth spring 425, and the end of the push rod 4211 close to the shell 1 is retracted into the adjustment hole 4221, and the adjustment ball 424 moves in the direction away from the shell 1 under the elastic force of the third spring 423, and is engaged in the adjustment groove 413 to lock the sliding of the lifting frame 41.
