Description

Technical Field

[0001] This application relates to the field of photovoltaic connector technology, and in particular to photovoltaic connector assembly and disassembly tools. Background Technology

[0002] A photovoltaic (PV) connector is an electrical connection used between PV modules and between PV modules and combiner boxes or inverters. A PV connector typically consists of a snap-fit ​​male and female connector, each including a connector body for cable routing and a threaded fastener. The stability of PV connectors is crucial for the stable operation of a PV power generation system; therefore, when a PV power generation system malfunctions, the PV connectors usually need to be inspected or maintained.

[0003] When inspecting or maintaining photovoltaic connectors, connector wrenches are usually needed to disassemble and assemble them. However, photovoltaic connectors produced by different manufacturers have different sizes and specifications. When disassembling and assembling photovoltaic connectors from different manufacturers, multiple sets of connector wrenches of different specifications are required, which increases material costs and makes the operation cumbersome. Utility Model Content

[0004] Therefore, it is necessary to provide a photovoltaic connector assembly / disassembly tool that is universal and applicable to photovoltaic connectors produced by different manufacturers.

[0005] One embodiment of this application provides a photovoltaic connector assembly / disassembly tool, comprising:

[0006] The wrench body has a through mounting port;

[0007] An adjusting ring, rotatably disposed in the mounting port; and

[0008] Multiple movable blades are provided, all of which are movably disposed in the mounting port and arranged circumferentially along the adjusting ring. Each movable blade includes a connecting end and a free end. The connecting end of the movable blade is connected to the adjusting ring, and the free end of the movable blade extends toward the center of the mounting port and can together form a first bayonet. The first bayonet is used to fix the fasteners of the photovoltaic connector. Rotating the adjusting ring can cause all the movable blades to swing in the same direction to adjust the diameter of the first bayonet or close the first bayonet.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, the adjusting ring is located on one side of the movable blade, and a support frame is fixed inside the mounting port. The support frame is located on the side of the movable blade away from the adjusting ring, and the support frame has a through clearance opening, which is opposite to the first bayonet.

[0011] In one embodiment, the adjusting ring has multiple first tracks, all of which are arranged sequentially along the circumference of the adjusting ring. The extension direction of each first track is perpendicular to the radial direction of the adjusting ring. The first tracks are arranged one-to-one with the movable blades. Each movable blade has a first connecting post protruding on the side near the adjusting ring. The first connecting post is inserted into the corresponding first track and can move and rotate on the first track.

[0012] The support frame has multiple second tracks, each corresponding to the movable leaf and the first track. The extension direction of the second track is at an acute angle to the extension direction of the corresponding first track. The movable leaf has a second connecting post protruding on the side near the support frame. The second connecting post is inserted into the second track and can move and rotate on the second track.

[0013] In one embodiment, the angle between the extension direction of the second track and the extension direction of the corresponding first track is 30° to 60°.

[0014] In one embodiment, the free end of the movable blade has a first inclined surface and a second inclined surface that intersect at an angle. In two adjacent movable blades, the first inclined surface of one movable blade abuts against the second inclined surface of the other movable blade. A vertex angle is formed between the first inclined surface and the second inclined surface. The sum of the angles of the vertex angles of all the movable blades is 360°. When the first latch is closed, the vertex angles of all the movable blades abut against each other. When the first latch is open, the vertex angles of all the movable blades separate from each other.

[0015] In one embodiment, the apex corner is rounded.

[0016] In one embodiment, the wrench body also has a through second notch, which includes an intersecting first notch and a second notch, the first notch and the second notch having different diameters.

[0017] In one embodiment, the wrench body is further provided with two protruding top buckles, which are spaced apart. The width of the top buckles gradually decreases along the protruding direction of the top buckles. The top buckles are used to disassemble the latch between the male and female heads of the photovoltaic connector.

[0018] In one embodiment, the wrench body is further provided with a handle for gripping, and the side of the handle is provided with a recessed structure.

[0019] In one embodiment, the wrench body has two mounting ports, which are located at both ends of the wrench body, and each mounting port is provided with an adjusting ring and a movable blade.

[0020] In the aforementioned photovoltaic connector assembly / disassembly tool, a through mounting port is opened on the wrench body, and multiple movable blades are arranged circumferentially within the mounting port. The connecting ends of the movable blades are connected to the adjusting ring, and the free ends of the movable blades extend towards the center of the mounting port and together form a first bayonet for fixing fasteners. At the same time, rotating the adjusting ring can cause all the movable blades to swing in the same direction to adjust the diameter of the first bayonet. Thus, the diameter of the first bayonet can be flexibly adjusted according to the size of the fasteners of the photovoltaic connectors to be assembled / disassembled, improving the versatility of the photovoltaic connector assembly / disassembly tool and making the photovoltaic connectors applicable to different specifications of photovoltaic connectors.

[0040] This application provides a photovoltaic connector assembly / disassembly tool for assembling and disassembling a photovoltaic connector 10. Specifically, to facilitate understanding of the technical solution of this application, a brief introduction to the basic structure of the photovoltaic connector 10 in related technologies is necessary. See [link to relevant documentation]. Figure 1 as well as Figure 2 The photovoltaic connector 10 in the related technology includes a male connector 11 and a female connector 12. The male connector 11 and the female connector 12 are respectively connected to the junction boxes 14 of different photovoltaic modules through cables 13. Both the male connector 11 and the female connector 12 include a body for passing through the cable 13 and a fastener 15 for locking the cable 13 to the body. The fastener 15 is threadedly connected to the body. The male connector body 111 is provided with a buckle 112, and the female connector body 121 is provided with a slot 122. The buckle 112 can be engaged in the slot 122, thereby realizing the connection between the male connector 11 and the female connector 12, and thus realizing the electrical connection between different photovoltaic modules.

[0041] Furthermore, when disassembling the photovoltaic connector 10, in addition to disassembling the snap-fit ​​112 connection between the male connector 11 and the female connector 12, it is also necessary to remove the fastener 15 from the body. Typically, a connector wrench is used to loosen the fastener 15 from the body. However, photovoltaic connectors 10 manufactured by different companies have different specifications, and the diameter of the fastener 15 also varies. Traditional connector wrenches have poor versatility and cannot be used for disassembling fasteners 15 of different diameters.

[0042] Based on this, one embodiment of this application provides a universal photovoltaic connector assembly / disassembly tool applicable to photovoltaic connectors 10 of different specifications. Specifically, see [link to relevant documentation]. Figure 3 as well as Figure 4One embodiment of the photovoltaic connector assembly / disassembly tool includes a wrench body 21, an adjusting ring 22, and multiple movable blades 23. The wrench body 21 has a through mounting opening 211. The adjusting ring 22 is rotatably disposed in the mounting opening 211. All movable blades 23 are movably disposed in the mounting opening 211, and all movable blades 23 are arranged circumferentially along the adjusting ring 22. Each movable blade 23 includes a connecting end and a free end. The connecting end of the movable blade 23 is connected to the adjusting ring 22, and the free end of the movable blade 23 extends toward the center of the mounting opening 211 and can collectively enclose to form a first bayonet 231. The first bayonet 231 is used to fix the fastener 15 of the photovoltaic connector 10. Rotating the adjusting ring 22 can cause all movable blades 23 to swing in the same direction to adjust the diameter of the first bayonet 231 or close the first bayonet 231.

[0043] Specifically, see Figure 4 When the adjusting ring 22 rotates in the first circumferential direction (e.g., clockwise), all the movable blades 23 swing uniformly to their right, thereby widening the first bayonet 231; combined with Figure 6 When the adjusting ring 22 rotates in the second circumferential direction opposite to the first circumferential direction (e.g., counterclockwise), all the movable blades 23 swing to their left side, thereby narrowing the first latch 231 until the first latch 231 is completely closed.

[0044] In one embodiment, as an example, when using the photovoltaic connector assembly / disassembly tool, the adjusting ring 22 is first rotated in the first circumferential direction, causing the movable blades 23 to swing uniformly to one side, thereby widening the first bayonet 231. Then, the fastener 15 of the photovoltaic connector 10 is placed into the first bayonet 231. Next, the adjusting ring 22 is rotated in the second circumferential direction, opposite to the first circumferential direction, causing all the movable blades 23 to swing uniformly to the other side, thereby narrowing the first bayonet 231 until all the movable blades 23 grip the fastener 15 together. At this time, by holding the body of the photovoltaic connector 10 with one hand and turning the wrench body 21 with the other hand, the fastener 15 can be easily loosened or tightened, thereby achieving quick and effortless assembly / disassembly of the fastener 15 of the photovoltaic connector 10.

[0045] In the aforementioned photovoltaic connector assembly / disassembly tool, a through mounting port 211 is opened on the wrench body 21, and multiple movable blades 23 are arranged circumferentially within the mounting port 211. The connecting ends of the movable blades 23 are connected to the adjusting ring 22, and the free ends of the movable blades 23 extend towards the center of the mounting port 211 and together form a first bayonet 231 for fixing the fastener 15. Since rotating the adjusting ring 22 can drive all the movable blades 23 to swing in the same direction to adjust the diameter of the first bayonet 231, the diameter of the first bayonet 231 can be flexibly adjusted according to the size of the fastener 15 of the photovoltaic connector 10 to be assembled or disassembled, thereby improving the versatility of the photovoltaic connector assembly / disassembly tool and making the photovoltaic connector 10 applicable to photovoltaic connectors 10 of different specifications.

[0046] Combination Figures 3 to 5 In one embodiment, the adjusting ring 22 is located on one side of the movable blade 23, and a support frame 26 is fixed inside the mounting opening 211. The support frame 26 is located on the side of the movable blade 23 away from the adjusting ring 22, and the support frame 26 has a through clearance opening 261, which is opposite to the first latch 231. The support frame 26 can confine the movable blade 23 within the mounting opening 211, preventing the movable blade 23 from falling out of the mounting opening 211. At the same time, by providing a clearance opening 261 opposite to the first latch 231 in the support frame 26, the support frame 26 can prevent the fastener 15 from extending into the first latch 231.

[0047] See Figure 5 In one embodiment, the adjusting ring 22 has multiple first tracks 221, all of which are arranged sequentially along the circumference of the adjusting ring 22. The extension direction of each first track 221 is perpendicular to the radial direction of the adjusting ring 22, and each first track 221 corresponds one-to-one with the movable blade 23. Combined with... Figure 7 Each movable blade 23 has a first connecting post 232 protruding from the side near the adjusting ring 22. The first connecting post 232 is inserted into the corresponding first track 221 and can move and rotate on the first track 221. For example, all the first tracks 221 are connected end to end to form a polygonal groove structure.

[0048] Furthermore, the support frame 26 has multiple second tracks 262, each corresponding to the movable blade 23 and the first track 221. The extension direction of the second track 262 forms an acute angle with the extension direction of the corresponding first track 221. A second connecting post 233 protrudes from the side of the movable blade 23 closest to the support frame 26. The second connecting post 233 is inserted into the second track 262 and can move and rotate within the second track 262. Specifically, the end of the second connecting post 233 facing away from the movable blade 23 passes through the second track 262 and is connected to a boss. The size of the boss is larger than the width of the track, thereby stabilizing the movable blade 23 and the adjusting ring 22 on the wrench body 21.

[0049] By using the first track 221 and the second track 262 to fit and guide the movement trajectory of the movable blades 23, it is ensured that when the adjusting ring 22 is rotated, all the movable blades 23 can swing in the same direction to adjust the size of the opening of the first bayonet 231. The structure is simple and easy to implement.

[0050] Optionally, in one embodiment, the angle between the extending direction of the second track 262 and the extending direction of the corresponding first track 221 is 30° to 60°. Specifically, the smaller the angle between the extending direction of the second track 262 and the extending direction of the corresponding first track 221, the faster the deflection speed of the movable blade 23 when the adjusting ring 22 is rotated. Correspondingly, the faster the diameter of the first bayonet 231 changes, and the larger the maximum diameter that the first bayonet 231 can open. However, if the angle between the extending direction of the second track 262 and the extending direction of the corresponding first track 221 is too small, the movable blade 23 may get stuck. Therefore, by configuring the angle between the extending direction of the second track 262 and the extending direction of the corresponding first track 221 to 30° to 60°, it is ensured that the diameter of the first bayonet 231 can be quickly adjusted when the adjusting ring 22 is rotated, while avoiding the problem of the movable blade 23 getting stuck during the adjustment process. For example, when the angle between the extension direction of the second track 262 and the extension direction of the corresponding first track 221 is 30° to 60°, the maximum opening diameter of the first bayonet 231 is 18mm-25mm.

[0051] See Figure 7 Optionally, in one embodiment, the free end of the movable leaf 23 has a first inclined plane 234 and a second inclined plane 235 intersecting at an angle, that is, the free end of the movable leaf 23 has a triangular structure. Combined with Figure 6In two adjacent movable blades 23, the first inclined surface 234 of one movable blade 23 abuts against the second inclined surface 235 of the other movable blade 23; a vertex angle 236 is formed between the first inclined surface 234 and the second inclined surface 235, and the sum of the angles of the vertex angles 236 of all movable blades 23 is 360°. For example, if there are 6 movable blades 23, then the angle of the vertex angle 236 of each movable blade 23 is 60°. Understandably, in other embodiments, the number of movable blades 23 may also be 3, 4, 5, 7, or 8, etc., and is not limited here.

[0052] Continue to see Figure 6 Furthermore, when the first latch 231 is closed, the apex 236 of all movable blades 23 abut against each other, thereby ensuring that there are no gaps between the movable blades 23 when the first latch 231 is closed. See also Figure 4 When the first bayonet 231 is opened, the apex 236 of all the moving leaves 23 separate from each other to ensure that the first bayonet 231 opens smoothly.

[0053] Alternatively, in one embodiment, the apex 236 is rounded to prevent the apex 236 of the movable leaf 23 from scratching the fastener 15 of the photovoltaic connector 10.

[0054] See Figure 4 The wrench body 21 also has a through second bayonet 212, which is used to fix the male connector body 111 or the female connector body 121. Specifically, when assembling or disassembling the fastener 15 of the photovoltaic connector 10, two photovoltaic connector assembly / disassembly tools can be used together. First, the fastener 15 is fixed through the first bayonet 231 of one photovoltaic connector assembly / disassembly tool, and the male connector body 111 or the female connector body 121 is fixed through the second bayonet 212 of the other photovoltaic connector assembly / disassembly tool. Then, holding the photovoltaic connector assembly / disassembly tool that fixes the male connector body 111 or the female connector body 121 with one hand, and turning the photovoltaic connector assembly / disassembly tool that fixes the fastener 15 with the other hand, the fastener 15 can be loosened or tightened. This avoids the problem of the male connector body 111 or the female connector body 121 rotating synchronously during the process of loosening or tightening the fastener 15.

[0055] Furthermore, the second bayonet 212 includes an intersecting first opening 2121 and a second opening 2122, the diameters of which are different. For example, both the first opening 2121 and the second opening 2122 are elliptical holes. The intersecting arrangement of the first opening 2121 and the second opening 2122 means that the major axis of the first opening 2121 intersects with the major axis of the second opening 2122, and the first opening 2121 and the second opening 2122 have an overlapping portion. By intersecting the first opening 2121 and the second opening 2122, the space occupied by the second bayonet 212 is reduced, thereby reducing the size and weight of the wrench body 21, and making the photovoltaic connector assembly and disassembly tool more convenient to use.

[0056] For example, in one embodiment, the diameter of the first port 2121 is 14mm-18mm, and the diameter of the second port 2122 is 18mm-21mm. This can satisfy the fixing of male connector bodies 111 or female connector bodies 121 of different sizes, further improving the versatility of photovoltaic connector assembly and disassembly tools.

[0057] See Figure 6 The wrench body 21 also has two protruding top clips 25, which are spaced apart. The top clips 25 are used to disengage the latch 112 between the male connector 11 and the female connector 12 of the photovoltaic connector 10. See details... Figure 2 The female connector body 121 of the photovoltaic connector 10 also has an observation port 123 that communicates with the slot 122, combined with Figure 8 When disassembling the clip 112, simply insert the two top clips 25 into the two observation ports 123 respectively. The top clips 25 can push out the clip 112 in the slot 122, thereby disassembling the clip 112 between the male head 11 and the female head 12 of the photovoltaic connector 10, so that the male head 11 and the female head 12 can be separated.

[0058] Furthermore, along the protruding direction of the top buckle 25, the width of the top buckle 25 gradually decreases, that is, the base of the top buckle 25 is wider and the top is narrower, thereby ensuring that the top buckle 25 can be inserted more smoothly and completely into the observation port 123 to release the latch 112 between the male head 11 and the female head 12. For example, the distance between the two top buckles 25 is 6mm-8mm, the protrusion height of each top buckle 25 is 12mm-15mm, the top width of the top buckle 25 is 2mm-3mm, and the base width of the top buckle 25 is 4mm-5mm.

[0059] See Figure 4In one embodiment, the wrench body 21 has two mounting ports 211, located at opposite ends of the wrench body 21. Each mounting port 211 contains an adjusting ring 22 and a movable blade 23. This creates two adjustable first latches 231 on the wrench body 21. If one first latch 231 is damaged, the other first latch 231 can still be used normally, preventing the photovoltaic connector 10 from being directly scrapped and reducing costs.

[0060] See also Figure 4 In one embodiment, the wrench body 21 is further provided with a handle portion 24 for gripping. Exemplarily, the handle portion 24 is located between two mounting ports 211, thereby facilitating the use of the photovoltaic connector assembly / disassembly tool. Furthermore, the handle portion 24 has recessed structures 241 on its sides, for example, two recessed structures 241 are provided on each of the two opposite sides of the handle portion 24, thereby making the handle portion 24 more ergonomic and convenient for five-finger gripping and force application.

[0061] Optionally, in one embodiment, the wrench body 21 is entirely made of plastic, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), and acrylonitrile-butadiene-styrene copolymer (ABS). This makes the photovoltaic connector assembly / disassembly tool lighter and easier to carry. For example, the length of the wrench body 21 is 150mm-200mm, the width is 50mm-80mm, and the thickness is 8mm-20mm.

[0062] For example, the adjusting ring 22 is an annular structure, and the adjusting ring 22 is clearance-fitted with the inner wall of the mounting port 211. Further, the outer diameter of the adjusting ring 22 is 30mm-50mm, and the width of the adjusting ring 22 is 5mm-20mm.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
