A top connecting block 8 is provided above the top plug-in column 3, and a wiring plug barrel 9 is provided at the bottom end of the top connecting block 8. A first connecting metal block 10 is provided in the wiring plug barrel 9, and a second connecting metal block 11 is provided in the top plug-in column 3. The top end of the bottom wiring board 5 extends into the wiring plug slot 4 and is connected to the second connecting metal block 11, and a side connecting block 12 is provided on the side of the top connecting block 8.

[0026] A conductive metal cylinder 13 is provided on the side connecting block 12, and the end of the conductive metal cylinder 13 is connected to the first connecting metal block 10. A connecting wire seat 14 is provided on the side of the conductive metal cylinder 13, and a connecting plug 15 is provided at one end of the connecting wire seat 14. A connecting fixing ring 16 is provided at the connection between the connecting plug 15 and the connecting wire seat 14. The connecting plug 15 is sleeved on the conductive metal cylinder 13, and a current conducting wire 17 is provided at the other end of the connecting wire seat 14, and the end of the current conducting wire 17 extends into the connecting plug 15.

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that the top plug-in column 3 and the top connecting block 8 are both made of insulating rubber material.

[0028] The connection between the wiring plug barrel 9 and the top plug-in column 3 is made safer, avoiding the electric shock caused by contact with the wiring terminal during the previous wiring removal process.

[0029] Embodiment 3: The difference between this embodiment and embodiment 1 is that a rubber pad is provided on the outer side of the bottom end of the wiring plug barrel 9, and a rubber pad is provided on the inner wall of the top end of the wiring plug slot 4.

[0030] The wiring plug barrel 9 can be inserted into the wiring plug slot 4 more conveniently and the wiring plug barrel 9 can be inserted into the wiring plug slot 4 more firmly.

[0031] Embodiment 4: The difference between this embodiment and embodiment 1 is that an external thread is provided on the outer side of the side connection block 12, an internal thread is provided inside the connecting fixing ring 16, and the side connection block 12 and the connecting fixing ring 16 are connected via threads.

[0032] This makes the connection and disassembly between the connecting wire seat 14 and the top connecting block 8 more convenient.

[0033] In this embodiment, since the internal space of the existing equipment is small and the disassembly and assembly of the terminal posts is relatively frequent, the small equipment space will cause great inconvenience to the disassembly of the terminal posts, and the work efficiency is low. In addition, during the manual disassembly process, the disassembly and assembly of some old-style equipment will take three minutes each time, and the terminal nut will often fall into the test pile body during the disassembly process and be lost, which will increase the maintenance time of the workers.

[0034] In summary, in the specific implementation, the original terminal is changed to be connected to the fixing bolt 7, and the fixing bolt 7 is rotated and inserted into the plug-in screw hole 6, so as to fix the connecting wire on the bottom terminal board 5, and the top of the bottom terminal board 5 extends to the wiring plug-in slot 4 and is connected to the second connecting metal block 11. The user inserts the wiring plug barrel 9 set at the bottom end of the top connecting block 8 into the wiring plug-in slot 4.

[0035] The first connecting metal block 10 provided in the terminal plug barrel 9 can contact and connect with the second connecting metal block 11, so that the connecting wire on the bottom terminal board 5 can conduct current. Since the terminal plug barrel 9 is inserted in the terminal plug slot 4 and can be plugged in and out, the connection and disassembly between the top connecting block 8 and the top plug-in column 3 is more convenient, which greatly improves the convenience of disassembly and assembly during maintenance.

[0036] The conductive metal cylinder 13 arranged on the side of the top connecting block 8 can be connected to the first connecting metal block 10. The connection between the top connecting block 8 and the connecting wire seat 14 is achieved by inserting a connecting tube 15 on the outside of the conductive metal cylinder 13, so that the end of the current conduction wire 17 inserted into the inside of the connecting wire seat 14 can be connected to the conductive metal cylinder 13, and the connecting fixing ring 16 is connected to the side connecting block 12 by threads, so that the connection between the connecting wire seat 14 and the top connecting block 8 is more stable.

[0037] It is also convenient for later disassembly and assembly, thus avoiding the occurrence of false connections during the wiring process, and the device can also consider extending this wiring method to constant potential instrument wiring, anode and cathode junction box wiring, insulating joint protection device wiring, drainage device terminal and other components, which can save manpower, improve safety performance, and meet the wiring current capacity effect, greatly facilitating the user's safe wiring operation and effectively saving the time required for maintenance.
