[0002] As the application of photovoltaic new energy becomes more and more widespread, photovoltaic connectors are also used more and more, and various brands have emerged. However, since there is no unified production standard for the appearance of photovoltaic connectors, the dimensions of various brands are very similar but different in size. Therefore, the sizes of connector unlocking tools of various brands are difficult to be compatible and used.

[0003] Photovoltaic connectors are used in industrial scenarios where power is plugged in and out. The standard requires that when photovoltaic connectors are disconnected, they must be unlocked with a special tool before they can be disconnected. Therefore, photovoltaic connectors of various brands generally provide unlocking tools suitable for their own brand connectors. Due to the inconsistent external dimensions of photovoltaic connectors, there are currently no unlocking tools that are compatible with multiple size spacings, and they cannot unlock products of other brands with inconsistent locking dimensions. When an inverter needs to use photovoltaic connectors of multiple brands with inconsistent external dimensions, it is necessary to provide maintenance personnel with a variety of connector unlocking tools, causing unnecessary waste and inconvenience.

[0004] Based on the above, the present application provides a tool that can adjust the unlocking harpoon spacing on the spot, so as to unlock photovoltaic connectors of various brands with different sizes, specifically an unlocking tool for photovoltaic connectors with variable spacing sizes.

[0031] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0032] like Figure 1-2 As shown, an unlocking tool for a photovoltaic connector with a variable spacing size includes a fixed plate body 1, a first adjusting part 2, a second adjusting part 3 and a third adjusting part 4. The first adjusting part 2 is arranged on one side of the fixed plate body 1, and is used to tighten the photovoltaic connector with a knob. The second adjusting part 3 is pluggable and arranged on the other side of the fixed plate body 1, and is used to be inserted into the tightening port of the photovoltaic connector for rotation. The second adjusting part 3 is two oppositely arranged fork heads 301 inserted into the inside of the other side of the fixed plate body 1, and the fork heads 301 can change the spacing between the two fork heads 301 by forward and reverse installation. The third adjusting part 4 is pluggable and arranged on the side of the fixed plate body 1. Both the first adjusting part 2 and the third adjusting part 4 are provided with a plate hole 5 for replacing the first adjusting part 2 and the third adjusting part 4 corresponding to the annular surface of different photovoltaic connectors.

[0033] Refer to the attached Figure 2-3 The inner annular surface of the plate hole 5 on the first adjusting portion 2 is set to be a continuous concave tooth shape, and the end of the fixed plate body 1 is provided with an open opening corresponding to the position of the plate hole 5 thereon.

[0034] Refer to the attached Figure 2-3 The third adjusting portion 4 includes an external plate body 401, one end of the external plate body 401 is in an arc shape, and the other end is in a long straight plate shape. The plate hole 5 is opened on the arc-shaped end surface of the external plate body 401, and the plate hole 5 on the external plate body 401 is set to a hexagonal hole shape, and the end of the external plate body 401 is also provided with an open opening corresponding to the position of the plate hole 5 thereon.

[0035] The plate holes 5 on the first adjustment portion 2 and the second adjustment portion 3 have different concave bite surfaces, which can cope with different external tooth surfaces of the photovoltaic connector.

[0036] Refer to the attached Figure 2-3 A side outer slot 103 is provided on the side of the fixed plate body 1, and a side inner bite slot 104 is also provided inwardly along the inner slot surface of the side outer slot 103, and a second protruding plate 402 inserted into the side inner bite slot 104 is provided on the outer side surface of the external plate body 401.

[0037] The second protruding plate 402 and the external plate body 401 are adapted to be inserted into the inner side biting groove 104 and the outer side clamping groove 103 to form a pluggable structure for fixing the plate body 1 and the third adjustment part 4 .

[0038] When the third adjustment part 4 is plugged into the fixed plate body 1, the unlocking tool in the present application can cope with photovoltaic connectors of different brands and types, and can quickly select whether to adjust the assembly according to the outer tooth surface of the photovoltaic connector;

[0039] When the third adjustment portion 4 is disengaged from the fixed plate body 1, the position of the inner bite groove 104 on the side of the fixed plate body 1 is vacant. When the two ends of the fixed plate body 1 are used for adjustment, the vacant position can be used to twist the fixed plate body 1 by leveraging force. Based on the above, whether the third adjustment portion 4 is plugged into the fixed plate body 1 can be determined by two usage measures based on the on-site situation, thereby improving the scenario adaptability of the unlocking tool in this application.

[0040] See attached Figure 3-4 The fixed plate body 1 is provided with two end outer slots 101 at one end relative to the first adjustment part 2, and the two end outer slots 101 are symmetrically arranged. The inner slot surface of the end outer slot 101 is also provided with an end inner bite groove 102 inwardly, which is characterized in that: the end of the fork head 301 is bent and protruded to form a fork mouth 302, the combined cross-section of the fork head 301 and the fork mouth 302 is "L"-shaped, and the outer side surface of the fork mouth 302 is provided with a first protruding plate 303.

[0041] The fork mouth 302 and the first protruding plate 303 are adapted to be inserted into the outer card slot 101 of the end portion and the inner bite slot 102 of the end portion, so as to form a pluggable structure for fixing the plate body 1 and the second adjustment portion 3 .

[0042] Furthermore, the asymmetric design of the unlocking harpoon part allows for a variety of spacing sizes when combined in pairs.

[0043] Embodiment 1:

[0044] like Figure 5 As shown, the second adjustment portion 3 is in a state of inner angle relative to each other, and the distance between the two fork heads 301 is set to L;

[0045] Embodiment 2:

[0046] like Figure 6 As shown, the inner angles of the second adjustment portion 3 are in the same direction, and the distance between the two forks 301 is set to M;

[0047] Embodiment three:

[0048] like Figure 7 As shown, the inner angles of the second adjustment portion 3 are in a state of divergence, and the distance between the two forks 301 is set to S;

[0049] By comparing Example 1, Example 2, and Example 3, the distance between the forks 301 in the three embodiments is L>M>S. As the distance between the forks 301 continues to decrease, the outer ring diameter of the adapted photovoltaic connector also continues to decrease. Photovoltaic connectors of different diameters can be adapted by adjusting the position of the fork 301. In summary, the present application designs the unlocking harpoon of the photovoltaic connector unlocking tool as a pluggable structure, and the second adjustment part 3 for unlocking the photovoltaic connector is designed to be asymmetrically plugged in to achieve unlocking of three different spacing sizes, so that the spacing of the unlocking harpoon can be adjusted on site by different plug-in combinations of the second adjustment part 3, thereby achieving adaptation to photovoltaic connectors of different spacings.

[0050] Furthermore, the unlocking tool is divided into two parts, which can be adjusted and assembled on site.

[0051] Furthermore, the pluggable connection between the second adjustment portion 3 and the fixed plate body 1 is not limited to a sliding groove or a wedge-shaped interference fit.

[0052] Furthermore, in order to achieve more matching sizes, more unlocking tools with different spacing sizes can be designed according to production requirements so as to be combined into more spacing sizes.

[0053] Furthermore, in order to achieve more matching sizes, more slot positions can be designed on the main body structure. For example, three or four slots for plugging and unplugging are designed at the end of the fixed plate 1. Different spacing sizes can be achieved by inserting the second adjustment part 3 into different card slots, so as to unlock more brands of photovoltaic connectors.

[0054] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
