[0036] In this embodiment, the toggle assembly 52 includes a connecting rail 5201 fixedly connected to the driving strip 5111, a mounting bracket 5202 is slidably connected to the connecting rail 5201, a toggle block 5203 is rotatably connected to the mounting bracket 5202, a counterweight block 5204 for keeping the toggle block 5203 vertical is fixedly connected to the toggle block 5203, a stopper 5205 for limiting the unidirectional rotation of the vertical toggle block 5203 is provided on the mounting bracket 5202, a guide rod three 5206 is also fixedly connected to the mounting bracket 5202, a guide plate one 5207 is fixedly connected to the cabinet 1, a guide groove one 5208 is provided on the guide plate one 5207, a guide plate 5209 is also rotatably connected to the guide plate one 5207, the guide plate 5209 is located at the intersection of the guide groove one 5208, and the guide rod three 5206 is slidably connected in the guide groove one 5208.

[0037] In this embodiment, a driven block 202 is fixedly connected to the drawer 2, and the shifting block 5203 can abut against the driven block 202 during the movement.

[0038] In this embodiment, the guide groove 5208 exists so that when the toggle block 5203 pushes the drawer 2 to the deepest point, the mounting bracket 5202 moves downward, so that the toggle block 5203 cannot hinder the movement of the driven block 202, so that the drawer 2 can be directly pulled out.

[0039] In this embodiment, the setting of the guide plate 5209 enables the toggle block 5203 to pass through the intersection point on the guide plate 5209 when the first guide rod 4035 on the mounting bracket 5202 moves to the intersection point during the process of pushing the driven block 202, avoiding the mounting bracket 5202 from falling and causing the toggle block 5203 to disengage from the driven block 202, so that the drawer 2 cannot be pushed to the deepest part of the cabinet body 1.

[0040] In this embodiment, the connection assembly 53 includes four guide rods 5301 uniformly and fixedly connected to the cabinet body 1. Two connecting rods 5302 are symmetrically and slidably connected to the four guide rods 5301. A fixed clamping strip 402 is fixedly connected to the two connecting rods 5302. A spring 5303 is connected between the end of the connecting rod 5302 and the cabinet body 1. A flange 5304 for blocking the connecting rod 5302 is provided at the end of the guide rod 5301.

[0041] In this embodiment, the actuating assembly 54 includes a second guide plate 5401 fixedly connected to the driving strip 5111. A second guiding groove 5402 is formed in the second guide plate 5401. A guiding slope 5403 is provided at the intersection point of the second guiding groove 5402. A connecting block 5404 is fixedly connected to the fixed clamping strip 402. A fourth guide rod 5405 is slidably connected to the connecting block 5404. The fourth guide rod 5405 is slidably connected in the second guiding groove 5402.

[0042] In this embodiment, the setting of the guiding slope 5403 enables the fixed clamping strip 402 to be reset under the push of the spring 5303 only when the fourth guide rod 5405 is completely reset. At this time, the drawer 2 is just pushed to the deepest part, which can avoid the fixed clamping strip 402 being reset halfway to lock the drawer 2, resulting in the drawer 2 being unable to be moved to the deepest part.

[0043] In this embodiment, the pluggable capacitor assembly 3 includes a plugging base 301 fixedly connected to the drawer 2. A limiting frame 302 is fixedly connected to the plugging base 301. A plurality of capacitor modules 303 are slidably connected in the limiting frame 302. A plurality of first power plugs 304 are uniformly and fixedly connected to the plugging base 301. A second power plug 305 is fixedly connected to each capacitor module 303. The second power plug 305 is slidably inserted into the corresponding first power plug 304.

[0044] When this expandable electrical cabinet with a pluggable capacitor structure is in use, the usage process is as follows:

[0045] Open the drawer: rotate the handle 201, the handle 201 drives the cylinder 4037 to rotate, because the guide rod 2 4036 is slidably connected in the spiral groove 4038, the movable rod 4032 and the block 4033 move away from the handle 201, because the guide rod 1 4035 is slidably connected in the inclined groove 4034, the movable card strip 401 is retracted into the drawer 2 and disengaged from the fixed card strip 402, the drawer 2 is unlocked, and then the handle 201 can be pulled out to draw the drawer 2, and the drawn drawer 2 can be locked by reversing the handle 201;

[0046] Replacement of capacitor: remove the old capacitor module 303 from the limiting frame 302, and then insert the new capacitor module 303 into the limiting frame 302. Under the restriction of the limiting frame 302, align the second power plug 305 on the inserted new capacitor module 303 with the second power plug 305 on the plug-in base 301, and then press the capacitor module 303 downward to connect the second power plug 305 with the first power plug 304. Under the action of the weight of the capacitor module 303 itself, the second power plug 305 and the first power plug 304 will not be separated;

[0047] Closing the drawer: first unlock the drawer 2, and then lock the drawer 2 after pushing the drawer 2 into the cabinet 1. After all the drawers 2 are pushed into the cabinet 1, in order to prevent the drawer 2 from not fully entering the cabinet 1, pull the pull rod 5102 from one end to the other end, and the connecting rod 2 5105 connected to the pull rod 5102 through the connecting rod 1 5104 will make a reciprocating translation motion, and the driving strip 5111 will also make a reciprocating translation motion in the opposite direction under the synchronization of the connecting rod 4 5108 and the symmetrical connecting rod 3 5107 and the connecting rod 5 5110;

[0048] When the driving strip plate 5111 moves, the second guide plate 5401 moves with the driving strip plate 5111. Since the fourth guide rod 5405 is slidably connected in the second guide groove 5402, the fixed card strip 402 will move a certain distance away from the drawer 2 and disengage from the movable card strip 401, so that the drawer 2 is unlocked. When the second guide plate 5401 is reset, the fixed card strip 402 will also be reset under the elastic force of the spring 5303, and will be re-engaged with the movable card strip 401 to lock the drawer 2.

[0049] During the movement of the driving strip 5111, the mounting bracket 5202 moves with the driving strip 5111. Since the vertical toggle block 5203 rotates unidirectionally, during the movement of the mounting bracket 5202, the toggle block 5203 will flip over under the push of the driven block 202 on the drawer 2, so that the toggle block 5203 can pass through the driven block 202. During the resetting process of the mounting bracket 5202, the drawer 2 is unlocked and in an unlocked state, and the toggle block 5203 cannot rotate. The toggle block 5203 will be pushed by the driven block 202 to move the fully entered drawer 2, so that after the drawer 2 is fully entered into the cabinet 1, the drawer 2 is locked.
