Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the embodiments of the present utility model.

[0032] In photovoltaic systems, the optimizer is a core component for improving power generation efficiency, and its installation and maintenance efficiency directly impacts system cost and reliability. However, traditional optimizers lack an integrated cable fixing structure, requiring external auxiliary materials such as nylon cable ties and tape for wire harness fixation, which is time-consuming and labor-intensive, resulting in low installation and fixing efficiency. Moreover, polymer cable ties or tapes are prone to embrittlement and breakage under long-term outdoor ultraviolet radiation and temperature and humidity cycles, leading to cable loosening. In addition, the disordered coiling of wire harnesses on the optimizer's casing, with crisscrossing and redundancy, increases maintenance difficulty.

[0033] In view of this, embodiments of this application propose a photovoltaic optimizer module and a photovoltaic system, integrating a cable organizer into the optimizer body. This allows for direct cable fixing to the optimizer body without the need for external auxiliary materials, simplifying the installation process and improving efficiency. Furthermore, the cable organizer neatly organizes the cables, resulting in a more orderly cable arrangement, reducing cable crossover and redundancy, and facilitating daily inspection and maintenance. Additionally, the cable management structure within the organizer can fix or organize the cables, while the clamping structure can hold them to the optimizer body, facilitating a more convenient detachable connection between the cable organizer and the optimizer body. This allows for independent installation or replacement of the cable organizer, further enhancing assembly convenience.

[0034] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0035] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a photovoltaic optimizer component, the photovoltaic optimizer component comprising:

[0036] The optimizer body 100, specifically, is a common photovoltaic optimizer, generally including a housing and electrical components housed inside the housing, which will not be described in detail here; and

[0037] The cable organizer 200 includes a cable management structure 210 and a clamping structure 220 connected to the cable management structure 210. The cable management structure 210 is clamped to the housing of the optimizer body 100 by the clamping structure 220. It is understood that the cable organizer 200 includes the cable management structure 210 and the clamping structure 220. The cable management structure 210 is disposed at one end of the clamping structure 220 and is used to fix or integrate the cable bundle. The clamping structure 220 is used to clamp onto the surface of the optimizer body 100, thereby fixing the entire cable organizer 200 and the optimizer body 100. Fixing the cable organizer 200 by clamping makes installation simpler and more convenient. Optionally, the clamping structure 220 clamps onto two opposite surfaces of the optimizer body 100. In one embodiment, the clamping structure 220 can be a commonly used clamp form, which is not limited here. In another embodiment, the cable management structure 210 can be a cable management rod 211 with a cable groove and a clamp. The cable can be wrapped around the cable management rod 211 and extended to the outside of the cable management rod 211 through the cable groove. The clamp is fitted on the outside of the cable and fixes the cable to the cable management rod 211.

[0038] In this embodiment, by integrating the cable organizer 200 onto the optimizer body 100, cables can be directly fixed to the housing of the optimizer body 100 without the need for external auxiliary materials, making the installation process simpler and more convenient, greatly simplifying the installation process and improving installation efficiency. Furthermore, the cable organizer 200 organizes the cables in an orderly manner, making the cable arrangement more organized, reducing cable crossover and redundancy, facilitating daily inspection and maintenance, and enabling quick positioning, thereby reducing maintenance costs and time. It also improves the appearance and cleanliness of the optimizer body 100, enhancing its overall aesthetics. In addition, the cable management structure 210 in the cable organizer 200 can fix or organize the cables, while the clamping structure 220 in the cable organizer 200 can clamp onto the optimizer body 100, thus facilitating a detachable connection between the cable organizer 200 and the optimizer body 100. This allows the cable organizer 200 to be installed or replaced independently, further improving assembly convenience. Furthermore, the installation location can be flexibly adjusted or different types of cable management structures can be replaced according to actual needs, making it suitable for various photovoltaic system configurations and improving the adaptability and versatility of the overall structure.

[0039] In one embodiment of this utility model, reference is made to Figure 4 and Figure 5The clamping structure 220 includes a fixing part 221, a first clamping part 222, a second clamping part 223, and a clamping adjustment member 224 connecting the first clamping part 222 and the second clamping part 223. The cable management structure 210 is connected to the fixing part 221. It is understood that the fixing part 221 provides an installation position for the first clamping part 222, the second clamping part 223, and the cable management structure 210, facilitating assembly. Optionally, the cable management structure 210 and the fixing part 221 are integrally formed, which reduces the assembly process and improves the reliability of the connection. Of course, in other embodiments, the cable management structure 210 and the fixing part 221 can also be connected and fixed by bolts, welding, etc., which is not limited here. The first clamping part 222 and the second clamping part 223 are spaced apart at both ends of the fixing part 221 to form a clamping space. The clamping adjustment member 224 drives the connection between the first clamping part 222 and the second clamping part 223, making the size of the clamping space adjustable. It is understood that the cable management structure 210 is disposed on one side of the fixing part 221, and the first clamping part 222 and the second clamping part 223 are disposed on the other side of the fixing part 221. The end of the first clamping part 222 near the cable management structure 210 and the end of the second clamping part 223 near the cable management structure 210 are respectively fixedly connected to the fixing part 221. The end of the first clamping part 222 away from the cable management structure 210 and the end of the second clamping part 223 away from the cable management structure 210 are spaced apart from each other, thereby forming a clamping space for clamping the optimizer body 100. Optionally, the fixing part 221, the first clamping part 222, and the second clamping part 223 are all plate-shaped structures, and the first clamping part 222 and the second clamping part 223 are integrally bent and formed with the fixing part 221. In this way, the assembly process can be further simplified and the reliability of the connection can be improved. In addition, the first clamping part 222 and the second clamping part 223 are connected by a clamping adjustment member 224. The clamping adjustment member 224 can adjust the distance between the end of the first clamping part 222 away from the fixed part 221 and the end of the second clamping part 223 away from the fixed part 221, that is, the size of the clamping space can be adjusted so that it can be clamped on the optimizer body 100 or removed from the optimizer body 100, thereby facilitating the installation and removal of the cable organizer 200 from the optimizer body 100.

[0040] In one embodiment of this utility model, reference is made to Figure 4The clamping adjustment component 224 includes a bolt 2241 and an adjusting nut 2242. The tail of the bolt 2241 passes through the first clamping portion 222 and the second clamping portion 223 to be threadedly connected to the adjusting nut 2242. Specifically, the clamping adjustment component 224 includes a bolt 2241 and an adjusting nut 2242. The first clamping portion 222 and the second clamping portion 223 are respectively provided with through holes. The tail of the bolt 2241 passes through the through holes of the first clamping portion 222 and the second clamping portion 223 in sequence. The adjusting nut 2242 is located on the side of the second clamping portion 223 opposite to the first clamping portion 222 and is threadedly connected to the tail of the bolt 2241. The head of the bolt 2241 abuts against the surface of the first clamping portion 222 opposite to the second clamping portion 223. Thus, with bolt 2241 fixed in place, rotating adjusting nut 2242 allows it to move axially along the shank of bolt 2241. This changes the distance between the head of bolt 2241 and adjusting nut 2242, thereby adjusting the clamping space. It is understood that the clamping space can be easily adjusted through the cooperation of bolt 2241 and adjusting nut 2242. Optionally, bolt 2241 is located at or below the center of the longitudinal direction of the first clamping part 222 and the second clamping part 223. This increases the contact area between the first and second clamping parts 222 and the optimizer body 100, improving the reliability of the clamping fixation.

[0041] In one embodiment of this utility model, reference is made to Figure 4 The clamping structure 220 further includes an anti-slip layer 225, which is provided on the surface of the first clamping part 222 facing the second clamping part 223 and / or the surface of the second clamping part 223 facing the first clamping part 222. To further improve the reliability of the clamping structure 220 in clamping the optimizer body 100, the anti-slip layer 225 is provided, which can increase the friction between the first clamping part 222 or the second clamping part 223 and the optimizer body 100, thereby improving the reliability of clamping and fixing. Optionally, the first clamping part 222 is provided with an anti-slip pad, or the second clamping part 223 is provided with an anti-slip layer 225, or both the first clamping part 222 and the second clamping part 223 are provided with an anti-slip layer 225. In one embodiment, the anti-slip layer 225 can be an anti-slip pad, an anti-slip groove, or an anti-slip protrusion; no limitation is made here. In another embodiment, the anti-slip layer 225 is disposed at the end of the first clamping part 222 or the second clamping part 223 away from the wire arrangement structure 210. This can reduce the area of ​​the anti-slip layer 225 and reduce the cost of use while ensuring increased friction.

[0042] In one embodiment of this utility model, reference is made to Figure 4 and Figure 5The cable management structure 210 includes a cable management rod 211 and a winding groove 212 on the cable management rod 211. The clamping structure 220 is located at one end of the cable management rod 211. Thus, the winding groove 212 on the cable management rod 211 can be used to organize or fix the cable. It is understood that the cable is wound in the winding groove 212. Optionally, the cable management rod 211 can be a cylindrical rod or a square rod, without limitation. One end of the cable management rod 211 can be connected and fixed to the fixing part 221 of the clamping structure 220 by a bolt structure or a welding structure. In one embodiment, the end of the cable management rod 211 away from the clamping structure 220 is provided with a latch 214. After the cable is wound around the cable management rod 211 a required number of times, such as 3 or 5 turns, it is fixed to the cable management rod 211 by the latch 214. Optionally, the latch 214 can be a clamp or other type of cable clip that can fix the cable, without limitation.

[0043] In one embodiment of this utility model, reference is made to Figure 4 The winding groove 212 extends spirally along the outer periphery of the cable management rod 211. Thus, when winding the cable, it is only necessary to wind it along the winding groove 212, allowing the cable to be dispersed axially along the cable management rod 211, preventing it from piling up and affecting heat dissipation. And / or, at least two winding grooves 212 are provided, each independent of the others. One winding groove 212 is used to wind the positive cable, and the other winding groove 212 is used to wind the negative cable, thereby enabling independent winding of the positive and negative cables. (Refer to...) Figure 1 .

[0044] In one embodiment of this utility model, reference is made to Figure 4 and Figure 5 The cable management structure 210 further includes a cable guide groove 213, which extends axially along the cable management rod 211 and communicates with the winding groove 212. Thus, after the cable is wound in the winding groove 212, the cable guide groove 213 guides the cable to the end of the cable management rod 211 away from the clamping structure 220, ensuring the cable can be exited in a predetermined direction. It is understood that the cable guide groove 213 can guide the wound cable to the predetermined position for exit. Optionally, the latch 214 is located at the end of the cable guide groove 213 away from the clamping structure 220, and the cable is fixed to the end of the cable guide groove 213 away from the clamping structure 220 by the latch 214.

[0045] In one embodiment of this utility model, reference is made to Figure 4 and Figure 5The fixing part 221 has a wire-passing notch 2211 around its periphery, through which the cable is wound around the cable organizer 200. The cable on the cable organizer 200 is led out from the optimizer body 100, and the cable can pass through the wire-passing notch 2211. It can be understood that the cable led out from the optimizer body 100 can be led out to the cable organizer 200 with the shortest path.

[0046] In one embodiment of this utility model, reference is made to Figure 3 Multiple cable organizers 200 are provided, and the multiple cable organizers 200 are arranged side by side in the housing of the optimizer body 100. In this way, cables of different electrical polarities (positive or negative) or different types can be organized or fixed.
