[0030] Terminal replacement is a very common operation in the maintenance and upgrade of power systems. The traditional terminal replacement method involves multiple steps, including dismantling the old terminal, handling the exposed wire ends, and installing the new terminal. Among them, handling the exposed wire ends is to avoid leakage of wire ends, to prevent short circuits or electric shock accidents, and thus ensure safety on site.

[0031] In the step of handling exposed wire ends, operators need to insulate and wrap the exposed wire ends. In the existing wrapping method, each time a wire end is removed, it needs to be operated, such as wrapping the wire end with insulating tape, which is not only inefficient, but also increases the duration and labor intensity of the operation. In pursuit of efficiency, some operators may directly skip this step, resulting in illegal operations and great safety risks.

[0032] In order to improve or solve the above technical problems, the inventors of the present application have proposed at least the following embodiments after long-term research.

When the terminal is connected to the power supply, the current can flow from the first pole of the power supply to the terminal through the first wire 5, and flow from the terminal to the second pole of the power supply through the second wire 6.

[0035] The voltage connection socket 22 may include a first sub-seat 221 and a second sub-seat 222. The first sub-seat 221 is used to connect the third wire 7.

One end of the fourth wire 8 is arranged in the second sub-seat 222, and the other end is connected to the terminal.

[0036] The current short-circuit assembly 3 may include a current short-circuit member 31, which is used to connect the first wire 5 in the incoming wire seat 211 and the second wire 6 in the outgoing wire seat 212, and short-circuit the first wire 5 and the second wire 6. When short-circuited, the first wire 5 and the second wire 6 form a loop from the current connection seat 21 to the power supply, and the first wire 5 and the second wire 6 are isolated from the current connection seat 21 to the terminal, so that the current of the power supply does not flow through the terminal.

[0037] The voltage connection assembly 4 includes a voltage connection member 41, which is used to connect the third wire 7 in the first sub-seat 221 and the fourth wire 8 in the second sub-seat 222. When the voltage connection member 41 is separated from the voltage connection seat 22, the third wire 7 and the fourth wire 8 are disconnected, thereby disconnecting the voltage loop.

[0038] In the structure provided in this embodiment, by setting the wire box 2 to connect the first wire 5, the second wire 6, the third wire 7 and the fourth wire 8, the current short-circuit component 3 can be used to conveniently realize the short circuit between the first wire 5 and the second wire 6, and the voltage connection component 4 can be used to conveniently control the disconnection or connection of the third wire 7 and the fourth wire 8, so that when performing the terminal replacement operation, the circuit can be safely and efficiently cut off at the wiring device 1, and the terminal can be isolated from the circuit, so that the wire ends of the first wire 5, the second wire 6, and the fourth wire 8 removed from the terminal no longer have the risk of leakage, and there is no need to wrap the exposed wire ends, so that the efficiency and safety of the terminal replacement operation can be effectively improved. In addition, since there is no need to include the wire ends, the amount of consumables such as insulating tape can be saved, the cost of the terminal replacement operation can be reduced, and the waste generated by the terminal replacement operation can be reduced.

Taking the first wire 5 and the incoming wire seat 211 as an example, the incoming wire seat 211 can be provided with a wiring hole 27 and a locking wire hole 28, the first wire 5 can be inserted into the wiring hole 27, the extension direction of the locking wire hole 28 intersects with the wiring hole 27, the locking wire screw 92 can pass through the locking wire hole 28 and extend into the wiring hole 27, the locking wire screw 92 is screwed with the inner wall of the locking wire hole 28, so that the first wire 5 is pressed against the wiring hole 27 by the locking wire screw 92, so as to achieve the connection and relative fixation of the first wire 5 and the incoming wire seat 211. Similarly, the second wire 6 and the outlet wire holder 212 , the third wire 7 and the first sub-holder 221 , and the fourth wire 8 and the second sub-holder 222 are not described in detail.

[0040] In a specific embodiment of the present application, the current shorting piece 31 may include two shorting plugs 311 and a first jumper 312, the two shorting plugs 311 and the first jumper 312 are conductors, and the first jumper 312 connects the two shorting plugs 311. One of the shorting plugs 311 is used to connect the first wire 5 in the incoming wire seat 211, and the other shorting plug 311 is used to connect the second wire 6 in the outgoing wire seat 212. Thus, the first jumper 312 and the shorting plug 311 are used to short-circuit the first wire 5 and the second wire 6, isolate the terminal from the current loop, reduce the risk of leakage of the first wire 5 and the second wire 6, and improve the efficiency and safety of the terminal replacement operation.

[0041] The voltage connection piece 41 may include two connection plugs 411 and a second jumper 412, the two connection plugs 411 and the second jumper 412 are conductors, the second jumper 412 connects the two connection plugs 411, one connection plug 411 is used to connect the third wire 7 in the first sub-seat 221, and the other short-circuit plug 311 is used to connect the fourth wire 8 in the second sub-seat 222. Thus, the third wire 7 and the fourth wire 8 are connected by the second jumper 412 and the connection plug 411, and after the voltage connection piece 41 is separated from the voltage connection seat 22, the voltage loop between the terminal and the power supply can be disconnected, the leakage risk of the fourth wire 8 is reduced, and the efficiency and safety of the terminal replacement operation are improved.

[0044] Optionally, the wiring holes 27 and the wire locking holes 28 can be further provided in the housing 23. Some of the wiring holes 27 on the housing 23 correspond one-to-one with the wiring holes 27 on the current wiring seat 21 and the voltage wiring seat 22, so that the first wire 5, the second wire 6, the third wire 7, and the fourth wire 8 can be inserted into the installation space 231 through the housing 23 for docking. Some of the wire locking holes 28 on the housing 23 correspond one-to-one with the wire locking holes 28 on the current wiring seat 21 and the voltage wiring seat 22, so that the wire locking screws 92 can be inserted into the installation space 231 through the housing 23 to tighten the first wire 5, the second wire 6, the third wire 7, and the fourth wire 8.
