[0019] In the present invention, both ends of the upper wiring board 3 of the upper wiring assembly and the lower wiring board 4 of the lower wiring assembly are connected in sliding fit with the inner wall of the box body 1. When wiring, the upper wiring board 3 and the lower wiring board 4 are pulled to move outward After reaching the opening position, wiring and fixing the cables, return the upper wiring board 3 and lower wiring board 4 to the box 1, which not only facilitates wiring and avoids wiring errors, but also ensures that the cables inside the box 1 are kept in order. Avoid cross confusion.

[0020] In a specific embodiment, the upper splint includes a first upper splint 13 and a second upper splint 14. The first upper splint 13 is fixed on the upper splint 3, and the first upper splint 13 is provided on the side away from the upper splint 3. A first upper fixing group, the first upper fixing group includes two adjacently arranged first upper half grooves 15, the inner wall of the first upper half groove 15 is provided with a first upper non-slip rubber layer 21, two first upper half grooves An upper bobbin 16 perpendicular to the first upper clamping plate 13 and extending outward is arranged between 15. The second upper clamping plate 14 is located on the side of the first upper clamping plate 13 away from the upper wiring board 3, and the second upper clamping plates 14 are all provided with an upper screw 17 which passes through the first upper clamping plate 13, the upper wiring board 3 and the upper nut 18 is connected and the upper screw 17 is in clearance fit with the first upper clamping plate 13 and the upper wiring board 3. The second upper splint 14 is provided with a plurality of second upper fixing groups on the side close to the first upper splint 13, and the plurality of second upper fixing groups are respectively arranged in one-to-one correspondence with the plurality of first upper fixing groups, and the second upper fixing groups include Two adjacently arranged second upper half grooves 19, the inner wall of the second upper half groove 19 is provided with a second upper non-slip rubber layer 22, between the two second upper half grooves 19 is provided for the insertion of the upper winding column 16 The upper positioning groove 20, the two second upper half grooves 19 of the second upper fixing group and the two first upper half grooves 15 of the corresponding first upper fixing group are respectively assembled into upper cable grooves for cables to pass through. When wiring, turn the upper nut 18 to disengage the upper screw 17, adjust the distance between the first upper splint 13 and the second upper splint 14, and pass the cable through a first upper half groove 15 of the first upper fixing group Then, after bypassing the upper bobbin 16 and then passing through another first upper half groove 15, move the second upper splint 14 to the first upper splint 13 and lock the upper nut 18 on the upper screw 17 to make the upper winding The wire post 16 is inserted into the upper positioning slot 20 to clamp the cable, which is convenient for fixing the cable.

[0021] In a specific embodiment, the lower terminal clamp includes a first lower clamp plate 23 and a second lower clamp plate 24. The first lower clamp plate 23 is fixed on the lower terminal plate 4, and the first lower clamp plate 23 is provided with a plurality of The first lower fixing group, the first lower fixing group includes two adjacently arranged first lower half grooves 25, the inner wall of the first lower half groove 25 is provided with a first lower non-slip rubber layer 31, and two first lower half grooves 25 There is a lower bobbin 26 perpendicular to the first lower clamping plate 23 and extending outward. The second lower splint 24 is located on the side of the first lower splint 23 away from the lower wiring board 4, and the second lower splints 24 are provided with a lower screw 27. The lower screw 27 passes through the first lower splint 23, the lower wiring board 4 and the lower nut 28 is connected and the lower screw 27 is in clearance fit with the first lower clamping plate 23 and the lower wiring board 4. The second lower splint 24 is provided with a plurality of second lower fixing groups on the side close to the first lower splint 23, and the plurality of second lower fixing groups are respectively arranged in one-to-one correspondence with the plurality of first lower fixing groups, and the second lower fixing groups include Two adjacently arranged second lower half grooves 29, the inner wall of the second lower half groove 29 is provided with a second lower anti-slip rubber layer 32, between the two second lower half grooves 29 is provided for the insertion of the lower bobbin 26 The lower positioning groove 30, the two second lower half grooves 29 of the second lower fixing group and the corresponding two first lower half grooves 25 of the first lower fixing group are assembled into lower cable grooves for cables to pass through. When wiring, turn the lower nut 28 to disengage the lower screw 27, adjust the distance between the first lower splint 23 and the second lower splint 24, and pass the cable through a first lower half groove 25 of the first lower fixing group Then, after bypassing the lower winding column 26, pass through another first lower half slot 25, move the second lower clamping plate 24 to the first lower clamping plate 23 and lock the lower nut 28 on the lower screw 27 to make the lower winding The post 26 is inserted into the lower positioning slot 30 to clamp the cable to facilitate the fixing of the cable.
