[0041] The working principle of the utility model is:

[0042] When the feeding module 3 slides away from the door cover 2, the feeding module 3 drives the two lower rotary rods 9 to rotate through the two first connecting rods, thereby driving the two isolation baffles 6 to rotate, and the two isolation baffles 6 move away from each other to expose the feeding module 3, so that the feeding module 3 can gradually engage with the contact seat 4, and at this time, the feeding module 3 is in a working state.

[0043] During the sliding process of the feeding module 3 away from the door cover 2, the feeding module 3 drives the linkage pin 13 to slide away from the door cover 2, the linkage pin 13 drives the upper end of the second connecting rod 11 to rotate away from the door cover 2, the lower end of the second connecting rod 11 rotates towards the door cover 2, and the second connecting rod 11 drives the grounding module 7 to slide towards the door cover 2 through the third connecting rod 12, so that the grounding contact 8 on the grounding module 7 is separated from the grounding terminal 5 on the inner wall of the shell 1, and the load side is not grounded at this time.

[0044] When the lower end of the second connecting rod 11 rotates towards the door cover 2, the fourth connecting rod 14 acts upwards, drives the end of the transverse section 23 of the fifth connecting rod 15 to rotate upwards, the longitudinal section 24 of the fifth connecting rod 15 rotates downwards, drives the sixth connecting rod 16 and the seventh connecting rod 17 to act downwards, thereby drives the one end of the rotary seat 18 away from the locking pin 21 to rotate downwards, the one end of the rotary seat 18 close to the locking pin 21 rotates upwards, the rotary seat 18 drives the action pin 25 to move towards the direction close to the sliding seat 20, the action pin 25 drives the locking pin 21 to slide towards the direction close to the pin seat 19, the spring 22 starts to rebound, the locking pin 21 is inserted into the pin seat 19, the door cover 2 is locked and cannot be opened, personnel cannot enter the inside of the shell 1, and the feeding module 3 is closed to be powered on.

[0045] When the feeding module 3 slides towards the door cover 2, the feeding module 3 gradually separates from the contact seat 4, the feeding module 3 drives the two lower rotary rods 9 to rotate through the two first connecting rods, thereby driving the two isolation baffles 6 to rotate, and the two isolation baffles 6 move close to each other until they contact each other, at this time, the feeding module 3 has been moved to the position, and the feeding module 3 and the contact seat 4 are physically isolated through the two isolation baffles 6 that contact each other, the isolation baffle 6 closes and blocks the live contact seat 4, and at this time, the feeding module 3 is in an exit state.

[0046] During the sliding of the power feeding module 3 towards the direction of the door cover 2, the power feeding module 3 drives the linkage pin 13 to slide towards the direction of the door cover 2, the linkage pin 13 drives the upper end of the second connecting rod 11 to rotate towards the direction of the door cover 2, the lower end of the second connecting rod 11 rotates towards the direction away from the door cover 2, the second connecting rod 11 drives the grounding module 7 to slide towards the direction away from the door cover 2 through the third connecting rod 12, so that the grounding contact 8 on the grounding module 7 is engaged with the grounding terminal 5 on the inner wall of the shell 1, thereby realizing the grounding of the load side.

[0047] When the lower end of the second connecting rod 11 rotates towards the direction away from the door cover 2, the fourth connecting rod 14 acts downwards, drives the end of the transverse section 23 of the fifth connecting rod 15 to rotate downwards, the longitudinal section 24 of the fifth connecting rod 15 rotates upwards, drives the sixth connecting rod 16 and the seventh connecting rod 17 to act upwards, thereby drives the rotating seat 18 to rotate upwards away from one end of the locking pin 21, the other end of the rotating seat 18 rotates downwards, the rotating seat 18 drives the action pin 25 to move towards the direction away from the sliding seat 20, the action pin 25 drives the locking pin 21 to slide towards the direction away from the pin seat 19, the spring 22 is stretched, the locking pin 21 is separated from the pin seat 19, and the door cover 2 is opened. Since the load side is grounded at this time, and the incoming end of the power feeding module 3 is absolutely not electrified, the physical power-off is high in safety, and when the switch device is faulty, the worker can be ensured to operate safely.
