An upper cover splicing notch 3 is opened on one side of the main body 1 of the terminal block, and two wiring plugs 6 are fixedly connected to one side wall of the upper cover splicing notch 3. A connecting copper wire 14 is connected to one side of the two wiring plugs 6;

[0028] A connecting copper plate 13 is arranged on the circumferential side of the connecting copper wire 14, and the connecting copper wire 14 is connected to the connecting copper plate 13 through a connecting piece;

[0029] The connecting piece includes a conductive external thread ring 15 fixedly connected to one side of the terminal body 1, a connecting copper wire 14 slidably connected inside the conductive external thread ring 15, a connecting copper plate 13 sleeved on the circumferential side of the conductive external thread ring 15, and a nut 16 threadedly connected to the circumferential side of the conductive external thread ring 15.

[0030] In this embodiment, when a fault occurs in the wiring plug rod 6 in one of the terminal bodies 1, after the power is disconnected, the nut 16 is rotated to disengage the nut 16 from the surface of the conductive external threaded ring 15, and the connecting copper plate 13 is removed. After the new terminal body 1 is aligned with the remaining terminal bodies 1, the connecting copper plate 13 is re-sheathed on the surfaces of multiple conductive external threaded rings 15, and the nut 16 is rotated to connect the connecting copper plate 13 to multiple terminal bodies 1, thereby achieving the replacement of a damaged terminal body 1 and reducing the loss caused by the replacement. Preferably, a connecting copper plate 13 is provided, and the number of conductive external threaded rings 15 and the nut 16 is the same as the number of connecting copper wires 14. The connecting terminal is connected by inserting the clamping limit block 4 and the wiring plug rod 6. The connecting copper plate 13 can conduct electricity, which can facilitate the connection of multiple connecting copper wires 14 to a power line.

[0031] For further details, please refer to Figure 1 The terminal body 1 is open, and an upper cover plate 2 is arranged above the terminal body 1 , and two clamping limit blocks 4 are arranged inside the terminal body 1 .

[0032] In this embodiment, the two upper cover plates 2 on the side can be connected to the two terminal bodies 1 on the side by locking buckles, and the upper cover plates 2 can be separated from the terminal bodies 1, making it convenient for maintenance personnel to inspect the terminal plugs 6 and the like inside the terminal bodies 1.

[0033] For further details, please refer to Figure 5 and Figure 2 The two clamping limit blocks 4 are both provided with clamping mechanisms 5 , and each set of clamping mechanisms 5 includes two clamping springs 501 , and the two clamping springs 501 are both fixedly connected between the clamping limit blocks 4 and the terminal body 1 .

[0034] In this embodiment, after the connection terminal is inserted into the upper cover splicing notch 3, the clamping limit block 4 is squeezed, and the clamping spring 501 is in a compressed state. Due to its own elasticity, the clamping spring 501 can push one side of the clamping limit block 4 to squeeze and clamp the connection terminal, improving the connection stability between the connection terminal and the wiring terminal body 1. Preferably, the two groups of clamping mechanisms 5 are respectively fixed to the inner bottom wall of the wiring terminal body 1 and the lower end of the upper cover plate 2. Preferably, the inner bottom wall of the wiring terminal body 1 and the lower end of the upper cover plate 2 are both provided with clamping grooves, and the clamping limit block 4, the clamping spring 501 and the telescopic rod 502 are all located in the grooves. A little extension outside the groove of the clamping limit block 4 can make the size of the connection terminal closer to that of the upper cover splicing notch 3, improving the stability.

[0035] Further, for details, please refer to Figure 5 , a telescopic rod 502 is arranged inside the clamping spring 501, and the telescopic rod 502 is fixedly connected between the wiring terminal body 1 and the clamping limit block 4.

[0036] In this embodiment, when the telescopic rod 502 enables the clamping limit block 4 to be squeezed and the clamping spring 501 is compressed, the clamping limit block 4 can move linearly, preventing the clamping limit block 4 from shifting in position due to the bending deformation generated when the clamping spring 501 is compressed.

[0037] Further, for details, please refer to Figure 1 and Figure 4 , the upper ends of several upper cover plates 2 are all provided with upper cover splicing notches 8, and the inner bottom walls of the upper cover splicing notches 8 are all fixedly connected with connecting rods 12. The upper ends of the connecting rods 12 are rotatably connected with rectangular clamping blocks 11. A connecting cover plate 9 is arranged in several upper cover splicing notches 8, and a plurality of rectangular grooves 10 are arranged at the upper end of the connecting cover plate 9.

[0038] In this embodiment, before installing the connecting cover plate 9, the orientation of the rectangular clamping block 11 is aligned with that of the rectangular groove 10. The connecting cover plate 9 is inserted into the upper cover splicing notch 8. The rectangular clamping block 11 passes through the rectangular groove 10 and exits the upper part of the notch of the rectangular groove 10. The rectangular clamping block 11 is rotated so that the rectangular clamping block 11 and the notch of the rectangular groove 10 are in a cross shape, which can fix the connecting cover plate 9 to a plurality of upper cover plates 2. Preferably, there is one connecting cover plate 9, and the number of the rectangular grooves 10, the upper cover splicing notches 8, the connecting rods 12 and the rectangular clamping blocks 11 is the same as that of the wiring terminal body 1.

[0039] Further, for details, please refer to Figure 3 , a clamping member is arranged between two adjacent wiring terminal bodies 1. The clamping member includes a limiting plate 17 and two limiting tracks 18. The limiting plate 17 and the two limiting tracks 18 are respectively fixedly connected to one side of the two wiring terminal bodies 1, and the limiting plate 17 is slidably connected in the two limiting tracks 18.

[0040] In this embodiment, before installing the connecting copper plate 13, the terminal block body 1 carrying the limiting plate 17 is inserted with the limiting plate 17 between two limiting rails 18 to achieve pre-limiting between the terminal block bodies 1, facilitating the installation of the connecting copper plate 13.

[0041] Further, for details, please refer to Figure 1 , an installation shell 7 is provided on one side of the terminal block body 1, and the conductive external thread ring 15, the nut 16, the connecting copper plate 13, and the connecting copper wire 14 are all located inside the installation shell 7.

[0042] In this embodiment, preferably, the installation shell 7 can be bolted to two of the terminal block bodies 1, or can be snap-connected through a snap block and a slot. The slot is opened on the installation shell 7, and the snap block is fixed on the terminal block body 1. The installation shell 7 can snap the snap block into the slot downward to achieve the connection.

[0043] The implementation principle of the above embodiment is as follows: When the wiring insertion rod 6 in one of the terminal block bodies 1 fails, after cutting off the power supply, the nut 16 is rotated to separate the nut 16 from the surface of the conductive external thread ring 15, and the connecting copper plate 13 is removed. After aligning the new terminal block body 1 with the remaining terminal block bodies 1, the connecting copper plate 13 is sleeved on the surfaces of multiple conductive external thread rings 15 again, and by rotating the nut 16, the connecting copper plate 13 can be connected to multiple terminal block bodies 1, thereby realizing the replacement of a damaged terminal block body 1 and reducing the losses caused by the replacement.

[0044] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0045] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
