[0031] The device has the effect of sealing the wire interface, specifically:

[0032] The surface of the housing 1 is penetrated with an inlet pipe 2, and two inlet pipes 2 are symmetrically arranged on the surface of the housing 1. A clamping hole 3 is arranged on the front surface of the housing 1, and the clamping hole 3 is arranged vertically to the inlet pipe 2, and two clamping holes 3 are arranged.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using the device, the wire can be connected to the device by passing it through the inlet tubes 2 on the upper and lower sides, and the wire is inserted into the inlet tube 2. After the wire enters the inlet tube 2, the swivel 6 is held and rotated to make the swivel 6 rotate on the outer surface of the inlet tube 2. The rotation of the swivel 6 drives the connecting rod 7 to rotate. The rotating connecting rod 7 pushes the block 5 to make the block 5 rotate on the inner wall of the inlet tube 2. The rotating block 5 pushes the sealing strip 4 inward, so that the sealing strip 4 fits tightly to the surface of the wire, thereby preventing water vapor from entering the housing 1 from the wire connection and causing leakage of the device.

[0034] This device has the effect of quickly compressing the wire, specifically:

[0035] A clamping structure is provided on the inner wall of the clamping hole 3. The clamping structure is provided with a clamping block 8 and a rotating rod 9, and the wire can be clamped with the help of a tool.

When the shell 1 is charged, the shell 1, the neon tube 10 and the neutral line form a current loop, so that the current passes through the neon tube 10, causing the neon gas to ionize and emit light, reminding the operator that the surface of the shell 1 is charged.

[0040] Working principle: when using the leakage-proof circuit breaker, insert the wire into the inlet pipe 2 so that the wire extends into the shell 1, rotate the swivel 6 on the outer surface of the inlet pipe 2, so that the swivel 6 drives the connecting rod 7 to rotate, and the connecting rod 7 drives the clamping block 5 to rotate, and the clamping block 5 pushes the sealing strip 4 inward, so that the sealing strip 4 fits tightly to the surface of the wire, thereby separating the connection of the wire from the outside world and preventing water vapor from entering the shell 1 to cause leakage. After the wire enters, pull out the pressing block 8 by the rotating rod 9, and the pressing block 8 can be driven to rotate by hand by holding the rotating rod 9, so that the pressing block 8 can be locked with the clamping hole 3 without using tools. A neon tube 10 is arranged on the surface of the shell 1. When the device shell 1 is energized, the neon tube 10 is ionized and emits light, reminding the operator to pay attention to safety, thereby increasing the overall practicality.
