[0047] See Figure 1 , Figure 2 , Figure 3 , Figure 4 This application provides a photovoltaic optimizer structure, including a housing 1. The housing 1 is composed of two parts assembled together, forming a cavity 11 between the two parts. A circuit board module 2 is provided in the cavity 11. At least one groove 12 is provided at the assembly position of the two parts of the housing 1. A wire hole plug 3 is provided in the at least one groove 12. A transmission line 4 is provided in the wire hole plug 3. One end of the transmission line 4 is connected to the circuit board module 2.
[0048] The photovoltaic optimizer structure provided in this application provides a housing 1 consisting of two parts assembled together, with a cavity 11 formed between the two parts. The circuit board module 2 can be installed in the cavity 11. A groove 12 is provided at the assembly position between the two parts for installing the wire hole plug 3 and the transmission line 4 inside. This photovoltaic optimizer structure is simple, easy to assemble, and can install the transmission line 4 while installing the circuit board module 2, reducing assembly steps, improving assembly efficiency, and thus reducing production costs.
[0049] In some embodiments, the cavity 11 can be a sealed chamber, thereby providing a sealed and waterproof seal for the circuit board module 2 installed within the cavity 11. The circuit board module 2 may include a printed circuit board and at least one device mounted on the printed circuit board; wherein, the device may include controllers, transistors, or other devices, without specific limitations. The transmission line 4 may include antennas, wires, data lines, etc.
[0050] In some embodiments, see Figure 2 , Figure 3 , Figure 4 The housing 1 has two parts, including a first outer shell 13 and a second outer shell 14, and a groove 12 is provided on the first outer shell 13 and / or the second outer shell 14.
[0051] Specifically, the first outer shell 13 and the second outer shell 14 are assembled together to form the shell 1, and a cavity 11 is formed between the first outer shell 13 and the second outer shell 14 to accommodate the circuit board module 2. Exemplarily, the first outer shell 13 and the second outer shell 14 are connected by four rivets 6. The connection between the first outer shell 13 and the second outer shell 14 by rivets 6 is merely an example; the connection between the first outer shell 13 and the second outer shell 14 can also be achieved by snap-fitting or bolts, and this application does not limit this to any particular method.
[0052] The groove 12 can be disposed on the first housing 13, the second housing 14, or both. For example, when the groove 12 is disposed on the first housing 13, the groove 12 is a U-shaped groove with one end opening toward the second housing 14; when the groove 12 is disposed on the second housing 14, the groove 12 is a U-shaped groove with one end opening toward the second housing 14.
[0053] During assembly, first, the wire-through hole plug 3 is placed on the transmission line 4, and the transmission line 4 is connected to the circuit board module 2. Then, the circuit board module 2 is installed inside the first housing 13, and simultaneously, the wire-through hole plug 3 is installed in the groove 12. Finally, the second housing 14 is assembled onto the first housing 13 and fixed in place. Of course, during assembly, the circuit board module 2 can also be installed inside the second housing 14 first, and then the first housing 13 can be assembled last. No specific limitation is made here.
[0054] The photovoltaic optimizer structure provided in this application embodiment is not only simple in structure and easy to assemble, but also eliminates the need for a separate assembly process to pass the transmission line through the wire hole on the housing, thereby reducing assembly steps, improving assembly efficiency, and thus reducing production costs.
[0055] In some embodiments, see Figure 5 The first outer shell 13 includes a first base plate 131 and a ring of first side plates 132 connected to the first base plate 131. A hollow structure with a first opening 133 is formed between the first base plate 131 and the first side plates 132. The second outer shell 14 is used to cover the first opening 133 and form a cavity 11. A groove 12 is provided on the first side plate 132. The connection interface between the first outer shell 13 and the second outer shell 14 can be sealed, for example, using a silicone strip, to improve the safety of the photovoltaic optimizer. It should be understood that the use of a silicone strip for sealing is only an example, and this application does not limit the specific sealing method. See also Figure 6The second housing 14 includes a second base plate 141 for covering the first opening 133. To improve assembly efficiency, the second housing 14 also includes a plurality of second limiting plates 142 connected to the second base plate 141 and extending to the outside of the first side plate 132. Accordingly, the second limiting plates 142 are used to limit and cooperate with the first side plate 132 during assembly to improve assembly accuracy and efficiency. The second limiting plates 142 are connected to the first side plate 132. For example, the second limiting plates 142 and the first side plate 132 are connected by rivets 6. Of course, the second limiting plates 142 and the first side plate 132 can also be connected by snap-fit, bolts, etc.
[0056] In some embodiments, the wire hole plug 3 is engaged within the groove 12. For example, see... Figure 4 The wire hole plug 3 is secured within the groove 12 via its slot 31. Furthermore, the connection and seal between the wire hole plug 3 and the groove 12 can be achieved through glue application, thereby improving the safety of the photovoltaic optimizer.
[0057] In some embodiments, the housing 1 includes a metal housing. Specifically, the first outer shell 13 and the second outer shell 14 are made of metal, which can be formed by sheet metal forming and welding, or by profile forming and cutting. The shape of the housing 1 can be cubic, cylindrical, or other shapes, and is not specifically limited here.
[0058] For example, the first housing 13 and the second housing 14 can be made of aluminum. Among metals of the same volume, aluminum is lighter and cheaper, which can reduce the weight and cost of the photovoltaic optimizer. For example, the first housing 13 and the second housing 14 can also be made of aluminum alloy. Other metals, such as copper and steel, which have high thermal conductivity and high strength, are also within the scope of protection of this application. It should be understood that in this application, the materials of the first housing 13 and the second housing 14 can be the same or different, and no specific limitation is made here.
[0059] The photovoltaic optimizer structure provided in this application embodiment, by setting the housing 1 as a metal housing, allows the heat generated by the circuit board module 2 to be dissipated through the metal housing, thereby achieving a good heat dissipation effect for the photovoltaic optimizer. Compared with the prior art, there is no need to install heat spreaders and heat sinks inside the housing, which further reduces the assembly difficulty and cost of the photovoltaic optimizer structure, while also reducing the size of the photovoltaic optimizer structure. In use, the housing 1 can also be grounded to increase the safety of the photovoltaic optimizer.
[0060] In some embodiments, the photovoltaic optimizer structure may further include potting compound used to fill the gap between the inner wall of the housing 1 and the circuit board module 2. Accordingly, the potting compound seals the circuit board module 2 within the housing 1, isolating it and achieving insulation. Furthermore, the potting compound can transfer heat generated by the circuit board module 2 to the housing 1, and then to the surrounding air outside the housing 1, enhancing the heat dissipation capability of the photovoltaic optimizer structure.
[0061] In this embodiment, a potting hole and a potting hole plug may be provided on the housing 1. Potting compound is filled into the gap between the inner wall of the housing 1 and the circuit board module 2 through the potting hole, and after the potting compound is formed, the potting hole is plugged with the potting hole plug so that the cavity 11 inside the housing 1 is sealed.
[0062] In some embodiments, see Figure 1 It also includes a mounting bracket 5, to which the housing 1 is connected. Specifically, the second housing 14 is connected to the mounting bracket 5. For example, a plurality of connecting ears 143 are provided on the second base plate 141 of the second housing 14, and the connecting ears 143 are connected to the mounting bracket 5 by screws, bolts or rivets. The mounting bracket 5 may be made of insulating material.
[0063] The photovoltaic optimizer structure provided in this application embodiment uses a mounting bracket 5 for installing the photovoltaic optimizer, thereby avoiding wiring along the edge of the photovoltaic panel, effectively shortening the line length, avoiding messy wiring on site, and reducing wiring and installation costs.
[0064] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
