[0002] Right-angle connectors typically consist of an "L"-shaped right-angle connecting plate and bolts. However, right-angle connectors used to connect flexible photovoltaic panels have an additional "U"-shaped connecting post. During installation, the right-angle connecting plate is first connected to the flexible photovoltaic panel using bolts. Then, the flexible photovoltaic panel is placed on the steel cable, and the connector is inserted into the right-angle connecting plate and secured with a nut. The steel cable then passes through the loop formed by the right-angle connecting plate and the connector, thus completing the connection between the steel cable and the flexible photovoltaic panel.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Example: Refer to Figures 1-8 Example: Refer to Figures 1-8A right-angle connector for connecting flexible photovoltaic panels includes a right-angle connecting plate 1, which is an inverted "L"-shaped plate with a horizontal top and vertical sidewalls. A through groove 14 is formed on the vertical sidewall, and mounting holes 12 are formed above and below the through groove 14, communicating with the through groove 14. The connector also includes a first bolt 2 threaded to the top of the right-angle connecting plate 1 for threaded fixation to the flexible photovoltaic panel; and a connecting post 3, which is "U"-shaped, with two straight rods inserted into the mounting holes 12. The arc-shaped rod of the connecting post 3 forms a collar with the vertical plate. The right-angle connecting plate 1 is a collar through which the steel cable of the flexible photovoltaic bracket passes; the fixing ring 7 is fitted onto the first bolt 2 and snapped into the connecting column 3; the connecting fixing component is set in the through groove 14 for fixing the connecting column 3; the fixing adjustment component is set on the connecting column 3 for fixing the steel cable; when the fixing adjustment component increases the frictional resistance between the collar and the steel cable, the fixing adjustment component drives the connecting fixing component to snap into the connecting column 3; the snap-fit ​​connecting component is set on the side plate of the right-angle connecting plate 1, and when the fixing adjustment component drives the connecting fixing component to snap into the connecting column 3, the snap-fit ​​connecting component snaps into the fixing adjustment component.

[0032] In use, firstly, the right-angle connecting plate 1 is connected to the bottom of the steel cable using the first bolt 2. Then, the vertical plate of the right-angle connecting plate 1 is attached to the steel cable. Next, the connecting post 3 is inserted into the mounting hole 12. Then, the fixing ring 7 is fitted onto the hexagonal screw head of the first bolt 2. Then, the connecting post 3 is pushed to engage and fix the fixing ring 7. When it is necessary to fix the flexible photovoltaic panel, the output end of the fixing adjustment component rises and cooperates with the connecting post 3 to clamp the steel cable and prevent the flexible photovoltaic panel from sliding. When the fixing adjustment component rises, the fixing adjustment component drives the connecting fixing component to be inserted into the connecting post 3 to fix the connecting post 3. Then, the fixing adjustment component is fixed by using the engaging connecting component. In summary, through the cooperation of multiple components, the photovoltaic panel and the steel cable are fixed, preventing the first bolt 2 from loosening due to weather conditions.

[0033] Reference Figure 1 A pulley 35 is rotatably connected to the connecting column 3. When the connecting column 3 is inserted into the right-angle connecting plate 1, the bottom of the pulley 35 is in contact with the steel cable. During use, the rolling friction between the connecting column 3 and the steel cable is converted into sliding friction by the pulley 35. When the photovoltaic panel needs to slide on the steel cable, the output end of the fixed adjustment component is lowered to release the steel cable, allowing the photovoltaic panel to move on the steel cable. The pulley 35 reduces the difficulty of moving the photovoltaic panel on the steel cable and prevents wear between the connecting column 3 and the steel cable, thus avoiding damage to the anti-corrosion coating on the surface of the connecting column 3 and the steel cable, thereby preventing a reduction in the corrosion resistance of the steel cable and the connecting column 3.

[0034] Reference Figure 2The connecting and fixing assembly includes a rotating shaft 5 rotatably connected within the through groove 14, a second adjusting plate 6 fixedly connected to the rotating shaft 5, a second connecting arm 61 rotatably connected to the second adjusting plate 6, and a locking block 62 rotatably connected to the second connecting arm 61. The locking block 62 is slidably connected in the through groove 14. A through hole 31 is provided on the connecting post 3. When the connecting and fixing assembly fixes the connecting post 3, the locking block 62 is inserted into the through hole 31. A mounting block 33 is fixedly connected to the connecting post 3, and a second threaded hole 3 is provided on the mounting block 3. 4. A second bolt 4 is threaded onto the second threaded hole 34. A knob 41 is fixedly connected to the bottom of the second bolt 4. A clamping block 42 is rotatably connected to the top of the second bolt 4 inside the collar. An arc-shaped groove 43 is opened on the clamping block 42, and an anti-slip layer 44 is provided in the arc-shaped groove 43. A mounting plate 51 is fixedly connected to the rotating shaft 5. A first adjusting plate 52 is fixedly connected to the mounting plate 51. A first connecting arm 53 is rotatably connected to the first adjusting plate 52. The first connecting arm 53 is rotatably connected to the side wall of the clamping block 42.

[0035] When in use, the second bolt 4 is driven to rotate by the knob 41. Under the limit of the first connecting arm 53, the second bolt 4 drives the clamping block 42 to rise. After the clamping block 42 rises, it cooperates with the connecting column 3 or the pulley 35 to clamp the steel cable, thereby fixing the photovoltaic panel and preventing the photovoltaic panel from sliding on the steel cable.

[0036] At the same time, the clamping block 42 drives the mounting plate 51 to rotate through the first connecting arm 53 and the first adjusting plate 52. The mounting plate 51 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the second adjusting plate 6 to rotate. The second adjusting plate 6 drives the locking block 62 to slide through the second connecting arm 61, so that the locking block 62 is inserted into the through hole 31 to fix the connecting post 3, prevent the connecting post 3 from sliding, and prevent the connecting post 3 from falling off the right-angle connecting plate 1.

[0037] Reference Figure 6 To prevent the locking block 62 from being inserted into the through hole 31, the end of the locking block 62 that is first inserted into the through hole 31 is set as an angled edge.

[0038] In this embodiment, while the second bolt 4 drives the clamping block 42 to rise and clamp the steel cable, the first connecting arm 53 drives the locking block 62 to be inserted into the through hole 31 to fix the connecting post 3. At the same time, the first adjusting plate 52 limits the clamping block 42 through the first connecting arm 53 to prevent the clamping block 42 from rotating, avoid the arc groove 43 from deviating from the axis of the steel cable, and improve the accuracy of the clamping block 42 in fixing the steel cable.

[0039] Reference Figure 1 and Figure 2The locking and connecting assembly includes a slide rod 8. A sliding hole 13 is provided on the vertical plate of the right-angle connecting plate 1. The slide rod 8 is slidably connected in the sliding hole 13. A baffle 81 is fixedly connected to one end of the slide rod 8 facing the second bolt 4. A spring 82 is sleeved on the slide rod 8. The two ends of the spring 82 are fixedly connected to the baffle 81 and the right-angle connecting plate 1, respectively. An insertion hole 45 is provided on the second bolt 4. When the fixing and adjusting assembly is fixed to the steel cable, the slide rod 8 is inserted into the insertion hole 45. A handle 83 is fixedly connected to the other end of the slide rod 8.

[0040] When the clamping block 42 and the pulley 35 clamp the steel cable, the sliding rod 8, under the guidance of the spring 82, is inserted into the insertion hole 45 on the second bolt 4 to limit and fix the second bolt 4 and prevent the second bolt 4 from sliding.

[0041] In summary, by driving the clamping block 62 to insert into the through hole 31 during the clamping action of the steel cable to fix the connecting column 3, there is no need to fix the nut on the connecting column 3, thereby improving the installation efficiency of the photovoltaic panel on site.

[0042] Reference Figure 1 and Figure 3 The top of the right-angle connecting plate 1 is provided with a first threaded hole 11, and the first bolt 2 is threaded into the first threaded hole 11. The first bolt 2 is fitted with a first washer 21 and a second washer 22. The first washer 21 is placed between the photovoltaic panel and the right-angle connecting plate 1, and the second washer 22 is placed between the nut of the first bolt 2 and the right-angle connecting plate 1.

[0043] Reference Figure 1 , Figure 2 , Figure 5 and Figure 8 The fixing ring 7 has an internal hexagonal hole 71, which is coupled to the hexagonal screw head of the first bolt 2. A connecting block 72 is fixedly connected to the side wall of the fixing ring 7, and a plug rod 73 is fixedly connected to the connecting block 72. A slot 32 is opened on the connecting post 3, and the plug rod 73 is used to be inserted into the slot 32.

[0044] When the connecting post 3 is not fully inserted into the mounting hole 12, insert the retaining ring 7 into the hexagonal screw head of the first bolt 2, and then continue to move the connecting post 3 so that the insert rod 73 is inserted into the slot 32. Then fix the connecting post 3. At the same time, the connecting post 3 and the first bolt 2 cooperate to engage and fix the retaining ring 7, and the retaining ring 7 is used to engage and fix the first bolt 2 to prevent the first bolt 2 from loosening during use. In addition, the first bolt 2 and the retaining ring 7 can also be set as a whole.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
