The photovoltaic panel junction box test device also includes a support table 6. In this embodiment, the pulley 4 is rotatably connected to the support table 6, so that if the cable 3 is separated from the photovoltaic panel junction box 1, it can be buffered by the pulley 4, reducing the friction between the cable 3 and the pulley 4, so that the weight block 5 can fall more smoothly. In other embodiments, the pulley 4 can also be fixedly connected to the support table 6. The cables 3 on both sides of the pulley 4 are arranged in parallel, that is, the photovoltaic panel junction box 1 can be evenly stressed, so that the test results are more accurate.

[0036] In some embodiments, the pressing member 2 is a quick clamp, which can be used to quickly and conveniently press the box body 11 of the photovoltaic panel junction box 1, thereby stably pressing the photovoltaic panel junction box 1 and improving the work efficiency of the entire test process.

[0037] In some embodiments, at least two pressing members 2 are arranged at intervals. In this embodiment, two pressing members 2 are arranged at intervals, so that the box body 11 of the photovoltaic panel junction box 1 can be pressed more stably, so that the stability of the connection between the box body 11 of the photovoltaic panel junction box 1 and the lower clamping block 12 to the cable 3 can be tested more accurately. In other embodiments, one or more pressing members 2 can be arranged according to the size of the photovoltaic panel junction box 1, so that the box body 11 can be pressed stably.

[0038] In some embodiments, the photovoltaic panel junction box testing device further includes a support member 9, which is used to support the weight block 5. The support member 9 supports the weight block 5, so that after the cable 3 is connected to the weight block 5, it can also be conveniently connected to the photovoltaic panel junction box 1. In some embodiments, the support member 9 is a cylinder, and in this embodiment, the cylinder is screwed to the support platform 6. By supporting the weight block 5 through the telescopic rod of the cylinder, the weight block 5 can be easily supported or removed from the weight block 5, so that the weight block 5 is suspended to stretch the cable 3; the weight blocks 5 of different weights can also be conveniently replaced by retracting the telescopic rod of the cylinder. In other embodiments, the support member 9 can be any structure that can be used to support or temporarily fix the weight block 5, such as an electric cylinder, an oil cylinder, a block-shaped object, a robotic arm, or the like.

[0039] Reference Figure 2 In some embodiments, the weight block 5 is connected with a hook 7. In this embodiment, the weight block 5 and the hook 7 are both made of metal. The hook 7 is welded to the weight block 5. The cable 3 is provided with a through hole 8, and the through hole 8 is used to hook the hook 7. The hook 7 is hooked on the cable 3 through the through hole 8, so that the weight block 5 can be conveniently connected to the cable 3.

[0040] Reference Figure 3In some embodiments, the photovoltaic panel junction box test device further includes a bottom plate 10, a plurality of screws 13 and a plurality of fixing nuts 14. The pressing member 2 is mounted on the bottom plate 10. In this embodiment, the pressing member 2 is fixed to the bottom plate 10 by welding. The bottom plate 10 is provided with a plurality of adjustment holes 15. One end of the screw 13 is connected to the support platform 6 so that the screw 13 can support the bottom plate 10. The other end passes through the adjustment hole 15. One screw 13 corresponds to at least two fixing nuts 14. In this embodiment, four screws 13 are provided and two fixing nuts 14 are provided. The fixing nuts 14 are all screwed to the screw 13 and respectively abut against the upper and lower end surfaces of the bottom plate 10. That is, in this embodiment, the upper and lower end surfaces of the bottom plate 10 abut against a fixing nut 14 respectively. By adjusting the position of the fixing nut 14, the bottom plate 10 can be fixed at different heights of the screw 13, so that the height of the pressing member 2 can be adjusted to better adapt to photovoltaic panel junction boxes 1 of different sizes. In other embodiments, two or more screw rods 13 may be provided according to actual needs; the upper and lower end surfaces of the base plate 10 may respectively abut against two or more fixing nuts 14, so that the base plate 10 can be fixed more stably.

[0041] In some embodiments, the support platform 6 is provided with a threaded hole, and the screw rod 13 is screwed into the support platform 6 through the threaded hole. The screw rod 13 can be conveniently fixed to the support platform 6 through the threaded hole provided on the support platform 6, so that the bottom plate 10 can be conveniently fixed.

The support nut 16 is screwed to the screw rod 13 and abuts against the support platform 6. This enables auxiliary fixing of the screw rod 13 so that the screw rod 13 can more stably support the bottom plate 10. In other embodiments, one screw rod 13 may correspond to two or more support nuts 16.

[0043] The implementation principle of a photovoltaic panel junction box testing device in an embodiment of the present application is as follows: when it is necessary to test the photovoltaic panel junction box 1, one end of the cable 3 is connected between the photovoltaic panel junction box 1 body and the lower clamping block 12, the box body 11 is fixed by the pressing piece 2, the weight block 5 is released, and the weight block 5 is allowed to be suspended in the air to stretch the cable 3 to see whether the cable 3 is detached from the box body 11 and the lower clamping block 12. If not, it means that the box body 11 and the lower clamping block 12 can maintain the connection stability under the weight of the weight block 5. If the cable 3 is detached from the box body 11, it means that the connection stability of the box body 11 and the lower clamping block 12 to the cable 3 is insufficient. Therefore, through the cooperation of the weight block 5 and the pressing piece 2, it is possible to conveniently test whether the photovoltaic panel junction box 1 can stably connect the cable 3.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
