[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] According to the attached Figures 1-6 As shown, an embodiment of the present utility model provides a wire arranging device for a photovoltaic module, including a box body 1. The box body 1 is a hollow structure with openings on both the upper and lower sides. A junction box 2 is provided on the box body 1 near the center. A partition frame 22 is provided at the center of the inner side of the junction box 2. Inlet boxes 3 are provided on both sides of the junction box 2. Symmetrically distributed inlet areas 31 are provided inside the inlet boxes 3. A number of evenly distributed wire arranging cavities 32 are separated by partitions inside the inlet areas 31. A wire passing hole 21 communicating with the junction box 2 is opened on the side wall of one side of the wire arranging cavity 32. An inlet hole 33 corresponding to the wire passing hole 21 is opened on the side wall of the other side of the wire arranging cavity 32. A wire pressing mechanism is provided inside the wire arranging cavity 32 near the side of the wire passing hole 21.

[0027] When connecting and fixing the lines of the photovoltaic module, each line is respectively passed through the inlet hole 33 into the inner side of the wire arranging cavity 32 and enters the inside of the junction box 2 through the wire passing hole 21 for wiring. Through the respective independent wire arranging cavities 32, the input wires can be separated according to a certain level and order, ensuring that the wires do not cross and tangle during the arrangement process. After wiring, the partition frame 22 can separate the respective wire connection heads from each other, avoiding interference between the wire connection heads, thereby improving the wire arrangement efficiency and the installation quality of the photovoltaic module.

[0028] Grooves corresponding to the respective wire passing holes 21 are provided on the partition frame 22. Limit frames 23 are provided on both the upper and lower sides of the partition frame 22. A number of evenly distributed card slots 24 are opened on the limit frames 23. The limit frames 23 are fixedly connected to the partition frame 22 by being clamped in the card slots 24.

[0029] The respective wire connection heads can be separated through the grooves on the partition frame 22, so that the respective wire connection heads are independently distributed, avoiding entanglement between the wire connection heads. After wiring, by making the limit frames 23 be in clamping cooperation with the partition frame 22, the wire connection heads can be further restricted and fixed, enhancing the protection of the wire connection heads and avoiding the wire connection heads being driven by the wires.

[0030] Connection frames 25 are provided on the inner walls of the junction box 2 near the upper and lower edges. First covers 26 are clamped and matched on both the upper and lower sides of the junction box 2. The first covers 26 are fixedly connected to the connection frames 25 by screws. After opening the first covers 26 on both the upper and lower sides, wiring work can be respectively carried out on both the upper and lower sides of the partition frame 22, improving the management effect of the wiring.

[0031] Second covers 34 are fixedly clamped on both the upper and lower sides of the inlet box 3. Pull rods 35 are provided near the four corners on the second covers 34. It is convenient to drive the second covers 34 through the pull rods 35.

[0032] Inside the wire management cavity 32 and on one side close to the wire inlet hole 33, there is a mounting bracket 4 welded and fixed. At the bottom of the mounting bracket 4, there are symmetrically distributed guide wheels 41. The guide wheels 41 are rotatably connected to the mounting bracket 4 through a rotating shaft. The guide wheels 41 are distributed on both sides of the wire inlet hole 33. When the wire passes through the wire inlet hole 33 and enters the inside of the wire inlet box 3, the wire can be guided by the guide wheels 41, reducing the friction between the wire and the edge of the wire inlet box 3, and thus reducing the abrasion of the wire inlet box 3.

[0033] Inside the wire management cavity 32, there are two groups of symmetrically distributed fixed rods 5 fixedly connected. A rotatable wire winding wheel 51 is sleeved on the outside of the fixed rod 5. When the remaining part of the wire is too long after wiring, the wire can be wound around the two wire winding wheels 51 to further organize the too-long wire, prevent the wire from being messy, and thus avoid the wire from being wound or knotted.

[0034] The wire pressing mechanism includes a fixing plate 6 and a pressing plate 61. The fixing plate 6 is fixedly connected to the inner wall of the wire management cavity 32. And symmetrically distributed telescopic rods 62 are arranged between the fixing plate 6 and the pressing plate 61, so that the pressing plate 61 is movably connected to the fixing plate 6. A spring 63 is sleeved on the outside of the telescopic rod 62. A dial block 611 is arranged on the pressing plate 61 and on the side close to the fixing plate 6.

[0035] When the dial block 611 is pushed, the telescopic rod 62 can be gradually contracted inward and compress the spring 63, so that the pressing plate 61 approaches the fixing plate 6, facilitating the wire to pass through the wire passing hole 21. After releasing the dial block 611, under the elastic action of the spring 63, the pressing plate 61 can squeeze and fix the wire near the wire passing hole 21, avoiding pulling on the connection head during the wire organizing process, effectively preventing the connection head from loosening, and ensuring the wiring quality of the photovoltaic module.

[0036] When the wire management device for a photovoltaic module of the present utility model is in use, first, open the first cover plate 26 and the second cover plate 34 on one side. Then, let the wire to be connected pass through the wire inlet hole 33, and let the guide wheels 41 guide the incoming wire. After that, pull up the dial block 611 to make the pressing plate 61 gradually approach the fixing plate 6. At the same time, pass the end of the wire through the wire passing hole 21, move the end of the wire to the inside of the junction box 2, and release the dial block 611. Under the elastic action of the spring 63, the pressing plate 61 fixes the wire. Then, wire the wire inside the junction box 2 and place the connection head in the groove on the partition frame 22. After that, make the card slot 24 on the limiting frame 23 be snap-connected and fixed with the partition frame 22 to limit and fix the connection head.

[0037] Further, when the remaining line is too long, wind the wire around the two wire winding wheels 51 to further organize the too-long wire, prevent the wire from being messy, and thus avoid the wire from being wound or knotted.
