[0025] Example 2

[0026] Based on Example 1, please refer to Figure 3, the clamping mechanism includes a positioning seat 101 arranged in the box body 1, and the positioning seat 101 is relatively arranged on both sides of the positioning hole 104, wherein a positioning rod 201 is slidably arranged between the positioning seats 101, and a clamping plate 202 is arranged on one side of the positioning rod 201 facing the positioning hole 104, and a handle 2 is arranged on the other side. A reset spring 204 is also arranged on the positioning rod 201, and one end of the reset spring 204 is fixedly connected to the positioning seat 101, and the other end is fixedly connected to the positioning rod 201; before fixing the line, first pull the handle 2 in the direction away from the positioning hole 104, and the handle 2 drives the positioning rod 201 to move. During the movement, the positioning rod 201 simultaneously drives the reset spring 204 to stretch and generate elastic force. When the line is inserted, release the handle 2, and the reset spring 204 drives the clamping plate 202 to move toward the line direction under the action of the elastic force, so as to realize the positioning and fixing of the line;

[0027] As a further solution of this embodiment, the clamping plate 202 is provided with an arc groove 203 in the direction of the positioning hole 104, and the circuit is embedded in the arc groove 203; it can be explained that when positioning the circuit, in order to improve the stability of the circuit, each group of circuits is respectively embedded in the arc groove 203 on the clamping plate 202, thereby making the circuit more stable and avoiding shaking.

[0028] The pushing mechanism includes a rack plate 402 fixedly connected to the shearing knife 403, the rack plate 402 can be slidably arranged on the outer side of the box body 1, wherein a gear 401 meshing with the rack plates 402 on both sides can be rotatably arranged on the box body 1, and the gear 401 is fixedly connected to the output end of the driving motor 4 fixedly arranged on the box body 1; it can be explained that when the shearing knife 403 is driven to move to shear the line, the driving motor 4 is started to drive the gear 401 to rotate, and the gear 401 pushes the shearing knife 403 to move by meshing with the rack plate 402 during the rotation process.

[0032] The working principle of an electrical box with leakage protection provided by the utility model is as follows: before fixing the line, first pull the handle 2 in the direction away from the positioning hole 104, the handle 2 drives the positioning rod 201 to move, and the positioning rod 201 synchronously drives the reset spring 204 to stretch and generate elastic force during the movement. When the line is inserted, the handle 2 is released, and the reset spring 204 drives the clamping plate 202 to move toward the line direction under the action of elastic force to achieve the positioning and fixation of the line. When the line in the box body 1 short-circuits and spontaneous combustion occurs, the smoke sensor 3 detects that there is smoke in the box body 1, and starts the drive motor 4 to drive the gear 401 to rotate. During the rotation, the gear 401 engages with the rack plate 402 to push the shear knife 403 to move. After the shearing is completed, the drive motor 4 reverses and drives the shear knife 403 to reset, so that the external line is separated from the internal line of the box body 1, thereby preventing the fire from being transferred along the line to the line outside the box body 1.
