[0039] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0040] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0041] like Figure 1 , 3 As shown, a wiring device according to an embodiment of the present invention includes:

[0042] The housing 1 has an opening 11 at its top;

[0043] End cap 2, which is detachably installed on the top of housing 1, is used to close opening 11;

[0044] Multiple wiring assemblies 3 are spaced apart along a first direction X. The lower end of the wiring assembly 3 is detachably installed at the bottom of the housing 1. The upper end of the wiring assembly 3 has a conductive part that extends upward out of the end cover 2 for connection with the wiring terminal of the energy meter.

[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 an adjusting part 42. The lifting frame 41 is connected to the housing 1 through the adjusting part 42. The housing 1 can slide relative to the lifting frame 41 in the third direction Z. The adjusting part 42 is used to adjust the relative positional relationship between the lifting frame 41 and the housing 1.

[0046] Among them, the first direction X is perpendicular to the third direction Z.

[0047] Based on the above technical solution, multiple wiring devices are arranged at intervals along the first direction X. The underground end of the wiring assembly 3 is detachably installed at the bottom of the housing 1. The multiple wiring assemblies 3 can be disassembled and assembled according to the number and position of the terminals of the energy meter, so that the number and position of the wiring assemblies 3 match the terminals of the energy meter. The wiring operation between the energy meter and the wiring device can be completed by directly plugging the conductive part of the wiring assembly 3 into the terminals of the energy meter. The operation is convenient and quick. A lifting assembly 4 is provided. The adjusting part 42 can adjust the relative position of the lifting frame 41 and the housing 1. After the terminals and conductive parts are plugged in, the position of the lifting frame 41 and the housing 1 can be adjusted by the adjusting part 42 to place the lifting frame 41 in a suitable position to avoid squeezing between the conductive part and the terminals, which would affect the conductivity of the wiring.

[0048] Preferably, such asFigure 3 , 7 As shown in Figure 8, the wiring assembly 3 includes a conductive post 31, a conductive post 32, a limiting nut 33, and a first spring 34. The conductive part is the conductive post 31. Both the conductive post 31 and the conductive post 32 extend in the third direction Z. The upper end of the conductive post 32 is provided with a first stud 321. The upper end face of the first stud 321 is provided with a threaded hole 322. The lower end of the conductive post 31 is provided with a second stud 311. The second stud 311 engages with the threaded hole 322. The first stud 321 engages with the limiting nut 33. The upper end face 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 conductive post 32. The upper end of the first spring 34 is connected to the limiting nut 33, and the lower end of the first spring 34 is connected to the bottom of the housing 1. The conductive post 31 and the conductive post 32 are detachably connected by the engagement of the second stud 311 and the threaded hole 322. Different sizes of conductive posts 31 can be replaced according to the structure of the terminals of different energy meters. The first stud 321 engages with the limiting nut 33. The first spring 34 is sleeved on the outer circumference of the conductive post 32. The two ends of the first spring 34 are respectively connected to the limiting nut 33 and the bottom of the housing 1. When the terminal is connected to the conductive post 31, the first spring 34 is compressed and contracted due to the pressure of the terminal on the conductive post 31. The conductive post 31 slides downward accordingly. The conductive post 31 and the terminal are in stable contact and conduction under stable pressure. The first spring 34 allows the conductive post 31 to slide in the vertical direction, which can adapt to the different depths of the terminals of different energy meters.

[0049] More preferably, such as Figure 5As shown, the bottom of the housing 1 has multiple through holes 12 and multiple positioning holes 13. The multiple through holes 12 are spaced apart along the first direction X. Each of the multiple through holes 12 corresponds to a multiple wiring assembly 3. The positioning holes 13 are located on one side of the through holes 12. The lower ends of the conductive posts 32 are inserted into the through holes 12. The lower end of the conductive post 32 is provided with a third stud 323. The upper end of the third stud 323 is fixedly fitted with a limiting plate 35. The upper surface of the limiting plate 35 is provided with a positioning post 351. The positioning post 351 is inserted into the positioning hole 13. The upper surface of the limiting plate 35 abuts against the bottom surface of the housing 1. The lower part of the limiting plate 35 is provided with a wire clamping nut 36. The wire clamping nut 36 is engaged with the third stud 323. A third stud 323 is provided at the lower end of the conductive post 32. A limit plate 35 is fixed on the third stud 323, and a wire clamping nut 36 is screwed onto it. When the wiring device needs to be connected to an external line, the wire of the external line is wound around the third stud 323. The wire clamping nut 36 is screwed on, and the wire clamping nut 36 and the limit plate 35 clamp the wire together, so that the wire is fastened to the third nut, making the wiring convenient and reliable. A positioning post 351 is provided at the upper end of the limit plate 35. The positioning post 351 is inserted into the positioning hole 13 of the housing 1 to prevent the conductive post 32 from rotating when it is connected to the energy meter. It can also provide a corrective force for the installation and removal of the limit nut 33. When the limit nut 33 is screwed into or removed from the first stud 321, the conductive post 32 will not rotate with the rotation of the limit nut 33, which increases the stability and convenience of installation and removal.

[0050] More preferably, such as Figure 4As shown, the wiring assembly 3 also includes a locking part 37. The end cover 2 has multiple through slots 21 spaced apart along a first direction X. The through slots 21 are located behind the conductive post 31. The conductive post 31 has a positioning groove 312 extending along a third direction Z, with the positioning groove 312 facing the through slot 21. The locking part 37 includes a stop 371, a second spring 372, a first slider 373, and a positioning block 374. The stop 371 is located at the bottom of the end cover 2, and the first slider 373 is partially accommodated in the through slot. In 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 disposed on the first slider 373 and the abutment 371. The positioning block 374 has a locked position and an unlocked position on its sliding path. When the positioning block 374 is in the locked position, the positioning block 374 is partially accommodated in the positioning groove 312. When the positioning block 374 is in the unlocked position, the positioning block 374 is not accommodated in the positioning groove 312. When the first slider 373 slides toward the abutment 371, it overcomes the elastic force of the second spring 372 and slides. The positioning block 374 slides with the first slider 373 from the locked position to the unlocked position. The positioning block 374 slides out of the positioning groove 312. At this time, the conductive post 31 is released from the restriction of the positioning block 374 and can be screwed out for easy replacement. When the first slider 373 slides away from the abutment 371, the elastic force of the second spring 372 drives the first slider 373 to slide. The positioning block 374 slides with the first slider 373 from the unlocked position to the locked position. The positioning block 374 is partially inserted into the positioning groove 312, restricting the rotation of the conductive post 31. At this time, the conductive post 31 and the conductive post 32 are relatively fixed, which can ensure that the conductive performance of the conductive post 31 and the conductive post 32 is stable and the conductivity is good after the wiring is completed.

[0051] In one specific embodiment, the length of the positioning groove 312 is less than the length of the positioning post 351. When the guiding post 31 is pressed and slides downward, the conducting post 32 slides downward at the same time. When the guiding post 31 slides to the point where the positioning block 374 abuts against the upper wall of the positioning groove 312, the positioning post 351 will not come out of the positioning hole 13, ensuring that the lower end of the conducting post 32 can slide stably and the sliding is more stable.

[0052] More preferably, a first anti-detachment groove 3711 and a second anti-detachment groove 3731 are respectively provided on the opposite sides of the abutment 371 and the first slider 373, and the two ends of the second spring 372 are respectively housed in the first anti-detachment groove 3711 and the second anti-detachment groove 3731. The first anti-detachment groove 3711 and the second anti-detachment groove 3731 respectively house the two ends of the second spring 372, so that even if the fixed connection between the second spring 372 and the abutment 371 and the slider fails, the first anti-detachment groove 3711 and the second anti-detachment groove 3731 can still hold the second spring 372 between the slider and the abutment 371, ensuring its reset function.

[0053] More preferably, such as Figure 1 As shown, the wiring device also includes a synchronous handle 5, and the locking part 37 also includes a transmission member 38. The synchronous handle 5 is slidably disposed on the outer edge of the end cover 2. The two ends of the transmission member 38 are respectively disposed on the first slider 373 and the synchronous handle 5. When the synchronous handle 5 is pulled, the first slider 373 slides backward against the elastic force of the second spring 372, 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 component 38 is a pull wire, and the end cover 2 has multiple wire holes. The two ends of the pull wire are connected to the synchronous handle 5 and the first slider 373 respectively. 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 respective wire holes, and all the first sliders 373 are pulled to slide in the direction of the abutment 371. All the positioning blocks 374 simultaneously disengage from their respective positioning grooves 312.

[0055] More preferably, such as Figure 1 , 2 As shown, the wiring device also includes a buckle plate 6, which is disposed on the upper surface of the end cover 2. The buckle plate 6 includes two plates 61 spaced apart along the second direction Y and multiple connecting ribs 62. The multiple connecting ribs 62 are arranged at intervals along the first direction X corresponding to the wiring assembly 3. The connecting ribs 62 extend along the second direction Y, and the two ends of the connecting ribs 62 are respectively connected to the two plates 61. A limiting post 63 is fixedly provided at the front end of the connecting rib 62. The limiting post 63 extends along the first direction X. A limiting groove 3741 extending along the first direction X is opened at the rear end of the positioning block 374. The limiting post 63 and the limiting groove 3741 are engaged and inserted.

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

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

[0058] Preferably, such as Figure 6 As shown, the lifting frame 41 has a lifting groove 411 on the side near the housing 1. The adjusting part 42 includes a push plate 421, a second slider 422, a third spring 423, an adjusting ball 424, and a fourth spring 425. The second slider 422 is fixedly mounted on the housing 1 and is housed in the lifting groove 411. The second slider 422 can slide relative to the lifting frame 41 in the third direction Z. An adjusting hole 4221 is provided at the end of the second slider 422 away from the housing 1. The adjusting hole 4221 is a blind hole. The two ends of the third spring 423 are respectively connected to the adjusting ball. The bottom of the hole 4221 and the adjusting ball 424, the outer diameter of the adjusting ball 424 is smaller than the inner diameter of the adjusting hole 4221, the lifting frame 41 is provided with a plurality of pushing holes 412 spaced apart along the third direction Z, the pushing holes 412 extend along the first direction X and communicate with the lifting groove 411, the end of the pushing hole 412 near the housing 1 is provided with an adjusting groove 413 that engages with the adjusting ball 424, the push plate 421 is provided with a plurality of pushing rods 4211 that engage with the pushing holes 412 and slide into each other, and the two ends of the fourth spring 425 are respectively provided on the push plate 421 and the lifting frame 41.

[0059] Specifically, pushing the push plate 421 causes the push rod 4211 to push the adjusting ball 424 to overcome the elastic force of the third spring 423 and disengage from the adjusting groove 413, moving it towards the adjusting hole 4221. At this time, the lifting frame 41 is moved. After determining the relative positional relationship between the housing 1 and the lifting frame 41, the push plate 421 is released. The push plate 421 is reset under the elastic force of the fourth spring 425. The end of the push rod 4211 near the housing 1 retracts back into the adjusting hole 4221. The adjusting ball 424 moves away from the housing 1 under the elastic force of the third spring 423 and engages in the adjusting groove 413, locking the sliding of the lifting frame 41. At this time, the housing 1 and the lifting frame 41 are relatively fixed, determining the relative positional relationship between the housing 1 and the lifting frame 41, thus completing the position adjustment.

[0060] More preferably, the lifting assembly 4 further includes a fixing part 43, which is disposed on the lifting frame 41 and is used to fix the lifting frame to the external structure.

[0061] Specifically, the fixing part 43 is a bolt that passes through the lifting frame 41 and is used to clamp the external structure between the bolt and the lifting frame 41.

[0062] In summary, this embodiment of the invention provides a wiring device in which multiple wiring devices are spaced apart along a first direction X. The lower end of the wiring assembly 3 is detachably installed at the bottom of the housing 1. The multiple wiring assemblies 3 can be disassembled and assembled according to the number and position of the terminals of the energy meter, so that the number and position of the wiring assemblies 3 match the terminals of the energy meter. The wiring operation between the energy meter and the wiring device can be completed by directly plugging the conductive part of the wiring assembly 3 into the terminals of the energy meter. The operation is convenient and quick. A lifting assembly 4 is provided, and the adjusting part 42 can adjust the relative position of the lifting frame 41 and the housing 1. After the terminals and conductive parts are plugged in, the positional relationship between the lifting frame 41 and the housing 1 can be adjusted by the adjusting part 42 to place the lifting frame 41 in a suitable position to avoid squeezing between the conductive part and the terminals, which would affect the conductivity of the wiring.

[0063] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
