[0040] In photovoltaic systems, MC4 connectors are widely used to connect photovoltaic panels and inverters to ensure the reliability and safety of electrical connections. These connectors often need to be disconnected during system maintenance or inspection. However, the existing tools for MC4 connectors on the market are mainly fixed-size wrenches, which are usually designed to tighten connectors rather than disconnect them. These fixed-size wrenches may be difficult to adapt to when there are slight differences in connector specifications or when the connector size changes due to long-term use and environmental factors. If an inappropriate tool is used to try to disconnect the MC4 connector, it will not only be inefficient, but may also cause damage to the connector, increasing system maintenance costs and safety risks. In addition, incorrect tool use will also increase the operator's labor intensity and operating difficulty, affecting the efficiency and safety of maintenance operations. Therefore, in view of these limitations of the prior art, there is an urgent need for a photovoltaic connector wrench that can adapt to MC4 connectors of different sizes and is specifically used for disconnection.

[0041] See also Figure 1 , an embodiment of the present application provides a photovoltaic connector wrench, including a handle 1, a fixed clamp 2, a movable clamp 3 and an adjusting member 4. Among them, the handle 1 is used to provide an installation position for the fixed clamp 2, the movable clamp 3 and the adjusting member 4, and to assist the user in holding the photovoltaic connector wrench. The fixed clamp 2 and the movable clamp 3 are used to cooperate to form a fixed opening for fixing the joint, so that the photovoltaic connector wrench can disassemble and extract the joint. The adjusting member 4 is used to adjust the distance between the movable clamp 3 and the fixed clamp 2, and then adjust the size of the fixed opening, so that the photovoltaic connector wrench can disassemble and extract joints of various specifications.

[0042] See also Figure 1 and Figure 2 In a specific configuration, the handle 1 has a mounting surface 11. The fixed clamp 2 is disposed on the mounting surface 11, the movable clamp 3 is slidably disposed on the mounting surface 11 along a first direction, the adjusting member 4 is disposed on the handle 1 and is transmission-connected to the movable clamp 3, and the adjusting member 4 can drive the movable clamp 3 to slide on the handle 1 along the first direction to adjust the distance between the first clamping surface 21 of the fixed clamp 2 and the second clamping surface 31 of the movable clamp 3, so that the photovoltaic connector wrench can clamp connectors of various specifications, and then perform disassembly and extraction work.

[0043] The fixed clamp 2 has a first clamping surface 21 and a first connecting surface 22 which are opposite to each other along a first direction, and the first clamping surface 21 and the first connecting surface 22 are both perpendicular to the mounting surface 11. The above structure allows the fixed clamp 2 to have a shorter length along the first direction, thereby facilitating the fixed clamp 2 to be inserted between two adjacent joints, thereby assisting the dynamic clamp 3 to clamp and fix one of the joints.

[0044] The movable clamp 3 has a second clamping surface 31 and a second connecting surface 32 which are opposite to each other along the first direction, and the second clamping surface 31 and the second connecting surface 32 are both perpendicular to the mounting surface 11. The above structure can make the movable clamp 3 have a smaller length along the first direction, thereby facilitating the movable clamp 3 to be inserted between two adjacent joints, thereby assisting the fixed clamp 2 to clamp and fix one of the joints.

[0045] In addition, the handle 1, the fixed clamp 2 and the movable clamp 3 are made of high-strength alloy materials to withstand repeated use and environmental impacts under outdoor working conditions. The first clamping surface 21 and the second clamping surface 31 are provided with soft materials that will not damage the surface of the MC4 connector, such as rubber or plastic, to protect the electrical connector from damage. The handle 1 is provided with an anti-slip structure to increase the comfort and operational stability during use. The adjustment member 4 has a locking mechanism to ensure that the distance between the fixed clamp 2 and the movable clamp 3 does not change during use.

[0046] In summary, the photovoltaic connector wrench of the present application can adjust the distance between the fixed clamp 2 and the movable clamp 3 through the adjusting part 4, so that the fixed clamp 2 and the movable clamp 3 can cooperate to clamp connectors of various specifications, so as to perform disconnect operations on connectors of various specifications, thereby improving the versatility and flexibility of the connector wrench, ensuring work efficiency and safety, and by making the first connecting surface 22 of the fixed clamp 2 and the second mounting surface of the movable clamp 3 both perpendicular to the mounting surface 11, it is convenient to insert the fixed clamp 2 and the movable clamp 3 between multiple MC4 connectors, and clamp and extract the corresponding MC4 connectors.

[0047] See also Figure 1 and Figure 2In one embodiment, the fixed clamp 2 further has a first oblique insertion surface 23, the first end of the first oblique insertion surface 23 is connected to the first connecting surface 22, the second end of the first oblique insertion surface 23 is connected to the first clamping surface 21, and as the distance between the second end and the mounting surface 11 decreases, the distance between the second end and the first connecting surface 22 gradually increases. The provision of the first oblique insertion surface 23 facilitates the fixed clamp 2 to be inserted between two adjacent joints, thereby assisting the dynamic clamp 3 to clamp and fix one of the joints.

[0048] The movable chuck 3 also has a second oblique insertion surface 33, the third end of the second oblique insertion surface 33 is connected to the second connection surface 32, the fourth end of the second oblique insertion surface 33 is connected to the second clamping surface 31, and as the distance between the fourth end and the mounting surface 11 decreases, the distance between the fourth end and the second connection surface 32 gradually increases. The second oblique insertion surface 33 can facilitate the movable chuck 3 to be inserted between two adjacent joints, thereby assisting the fixed chuck 2 to clamp and fix one of the joints.

[0049] In one embodiment, the fixed chuck 2 further has a first abutting surface 24, which is disposed on one end of the first clamping surface 21 facing the mounting surface 11, and the first abutting surface 24 is disposed obliquely to the first clamping surface 21. The movable chuck 3 further has a second abutting surface 34, which is disposed on one end of the second clamping surface 31 facing the mounting surface 11, and the second abutting surface 34 is disposed obliquely to the second clamping surface 31. When the fixed chuck 2 and the movable chuck 3 clamp the joint, the first abutting surface 24 and the second abutting surface 34 can abut against the joint, so that the fixed chuck 2 and the movable chuck 3 can more easily disassemble and extract the joint.

[0050] Specifically, the angle between the first abutting surface 24 and the first clamping surface 21 is an obtuse angle, so that the fixed clamp 2 has a larger contact area with the joint, thereby improving the fixing effect. The angle between the second abutting surface 34 and the second clamping surface 31 is an obtuse angle, so that the dynamic clamp 3 has a larger contact area with the joint, thereby improving the fixing effect.

[0051] See also Figure 1 and Figure 3 In one embodiment, the adjusting member 4 includes an adjusting member 41 and a locking member 42. The adjusting member 41 is rotatably disposed on the handle 1 and is transmission-connected to the dynamic chuck 3. The adjusting member 4 can drive the dynamic chuck 3 to slide on the handle 1 when rotating to adjust the size of the fixed space; the locking member 42 is movably connected to the handle 1 and can lock the rotation angle of the adjusting member 4 to ensure that the dynamic chuck 3 does not slide accidentally during use.

[0052] Specifically, in one embodiment, the adjusting component 41 includes an adjusting wheel 411, the surface of the adjusting wheel 411 is provided with threaded teeth, the moving portion 35 of the dynamic chuck 3 is provided with a threaded groove, and the adjusting wheel 411 is threadedly connected with the dynamic chuck 3 through the threaded teeth. When the user rotates the adjusting wheel 411, the adjusting wheel 411 can drive the moving portion 35 of the dynamic chuck 3 to move through the threaded teeth thereon, thereby adjusting the position of the dynamic chuck 3. It can be understood that in order to facilitate the user to rotate the adjusting wheel 411, a through hole is provided on the handle 1, and the adjusting wheel 411 is arranged in the through hole, and the user can rotate the adjusting wheel 411 through the through hole. The locking component 42 includes a locking block 421, and the locking block 421 can abut against the adjusting wheel 411 when the locking portion moves relative to the handle 1, so as to lock the rotation angle of the adjusting wheel 411.

[0053] In another embodiment not shown, the adjusting component 41 includes an adjusting wheel 411, which is a gear. A roller rack is provided on the moving portion 35 of the movable chuck 3, and the gear is meshed with the roller rack. When the user rotates the gear, the roller rack can drive the movable chuck 3 to move, thereby adjusting the position of the movable chuck 3. It can be understood that in order to facilitate the user to rotate the gear, a through hole is provided on the handle 1, the gear is arranged in the through hole, and a rotating shaft is provided at the axis of the gear. The user can rotate the rotating shaft through the through hole to rotate the gear. The locking component 42 includes a locking block 421, which can abut against the gear when the locking portion moves relative to the handle 1 to lock the rotation angle of the gear.

[0054] See also Figure 1 , Figure 3 and Figure 4 In one embodiment, the locking component 42 further includes a linkage, which is disposed in the handle 1 and connected to the locking block 421. The user can drive the locking block 421 to move through the linkage, so that the locking block 421 abuts against the adjusting wheel 411 to lock the rotation angle of the adjusting wheel 411.

[0055] Specifically, in one embodiment, the linkage includes a lever 422, a button 423 and a self-locking seat 424. The lever 422 is rotatably arranged in the handle 1. The button 423 and the locking block 421 are respectively arranged at the axial ends of the lever 422. When the user presses the button 423, the lever 422 can be rotated so that the locking block 421 abuts against the adjusting wheel 411, thereby locking the rotation angle of the adjusting wheel 411. A self-locking rod is provided on the side of the lever 422 away from the button 423. The self-locking rod is slidably arranged on the self-locking seat 424 to enhance the stability of the lever 422 when rotating. In addition, in order to facilitate resetting, a first spring is sleeved on the button 423, and the two ends of the first spring abut against the handle 1 and the lever 422 respectively. A second spring that can abut against the self-locking rod is provided in the self-locking seat 424. When the user presses the button 423 to make the lever 422 drive the locking block 421 to abut against the adjusting wheel 411, the first spring is stretched under the drive of the lever 422, and the second spring is stretched under the push of the self-locking rod. When the user no longer presses the button 423, the lever 422 and the self-locking rod can be reset under the drive of the first spring and the second spring, thereby resetting the button 423.

[0056] In another embodiment not shown, the linkage includes a push rod and a push key, the push key is slidably disposed on the handle 1, and both ends of the push rod are respectively connected to the push key and the locking block 421. When the user pushes the push key, the push rod can move so that the locking block 421 abuts against the adjusting wheel 411, thereby locking the rotation angle of the adjusting wheel 411.

[0057] See also Figure 1 and Figure 3 More specifically, in order to improve the locking effect of the locking component 42 on the adjusting component 41, the locking block 421 is a triangular block. When the locking block 421 abuts against the adjusting wheel 411, the triangular block can be inserted into the thread or gear of the adjusting wheel 411 to enhance the locking effect on the adjusting wheel 411.

[0058] See also Figure 1 In one embodiment, the photovoltaic connector wrench further includes a tightening head 5, which is disposed on the handle 1, and a tightening port for tightening the connector is provided on the tightening head 5. The photovoltaic connector wrench can not only remove and extract the connector, but also install the connector. Specifically, the tightening head 5 is disposed on the side of the handle 1 away from the mounting surface 11, so that the dynamic clamp 3 and the fixed clamp 2 will not affect the user's use of the tightening head 5, and the tightening head 5 will not affect the user's use of the dynamic clamp 3 and the fixed clamp 2.
