At present, most maintenance personnel use a flat-blade screwdriver or a small pry to remove it. However, due to the particularity of the photovoltaic power generation system, the power supply cannot be completely disconnected or released during daytime maintenance work. When the maintenance personnel remove the MC4 connector, it is often due to the photovoltaic string short circuit or line insulation damage, etc., which will cause strong arcs and dazzling white light, causing serious physical injuries to the maintenance personnel.

[0023] During use, the connector sockets 2 on the inner sides of the two semi-cylindrical tubes 1 are turned to be horizontal, and then the MC4 connector is wrapped with the two semi-cylindrical tubes 1. At this time, the connector sockets 2 in the two semi-cylindrical tubes 1 will be inserted into the two sides of the shrapnel of the MC4 connector, thereby pressing the shrapnel. Then the two handles 3 are rotated in opposite directions, and the connector sockets 2 are driven to rotate by the handles 3. The two connector plugs 2 will separate the MC4 connector. Then, the two semi-cylindrical tubes 1 are held and pulled downward together to pull down the separated MC4 connector to complete the disassembly. During the disassembly process, this dismantling tool wraps the MC4 connector with the semi-cylindrical tubes 1 throughout the entire process, thereby shielding the strong electric arc and dazzling white light generated during the disassembly process to prevent maintenance personnel from being injured.

[0024] In the embodiment shown in the present application, the two semi-cylindrical tubes 1 have the same length, and the connector socket 2 has a rectangular slot, and the slot on the connector socket 2 can match the two sides of the two springs on the MC4 connector.

[0025] In some embodiments, the heights of the connector sockets 2 inside the two semi-cylindrical tubes 1 are the same. During use, the two connector sockets 2 can compress all the springs on both sides of the MC4 connector, thereby ensuring that the springs are pressed in place to avoid errors.

[0026] In some embodiments, the opening of the connector socket 2 expands outwards, so that it is more convenient to insert the connector socket 2 into the springs on both sides of the MC4 connector.

[0028] Specifically, the connector socket 2 is disposed in the mounting groove 10 , and the connector socket 2 is driven to rotate up and down in the mounting groove 10 by the handle 3 . The mounting groove 10 serves as an avoidance function and provides a rotation space for the rotation of the connector socket 2 .

[0029] In some embodiments, the rotating shaft on the connector socket 2 extends out of the through hole and is connected to the handle 3 .

[0030] In order to facilitate the disassembly and assembly of the handle 3 and the connector socket 2 , in some embodiments, the rotating shaft on the connector socket 2 is detachably connected to the handle 3 .

[0031] Specifically, a flat plate is provided at one end of the connector socket 2 extending out of the through hole, and a pin hole is provided on the flat plate. A slot is provided at one end of the handle 3 for connecting the rotating shaft, and the slot is also provided with a pin hole. The flat plate on the rotating shaft is embedded in the slot, so that the pin holes of the two are aligned, and then a pin is inserted into the aligned pin hole to connect the handle 3 to the rotating shaft.

[0032] In order to increase the friction between the two semi-cylinders 1 when aligned, in some embodiments, a rubber layer 4 is provided on the inner side of the semi-cylinders 1 .

[0033] In the embodiment shown in the present application, the rubber layer 4 is arranged below the joint socket 2 .

[0034] In some embodiments, the rubber layer 4 is detachably connected to the inner side of the semi-cylindrical tube 1 .

[0035] The rubber layer 4 includes an arcuate portion 40 and a planar portion 41 connected to both sides of the arcuate portion 40. The arcuate portion 40 of the rubber layer 4 fits in the groove of the semi-cylindrical tube 1, and the planar portion 41 of the rubber layer 4 fits on the groove edge of the semi-cylindrical tube 1. The planar portion 41 is connected to the groove edge of the semi-cylindrical tube 1 by screws.
