[0029] Photovoltaic box, also known as photovoltaic combiner box, is an important part of photovoltaic power station system. Its main function is to collect and gather DC power from multiple solar panels, and then properly protect it and transmit it to the inverter. At the same time, photovoltaic combiner box can realize remote monitoring and component fault diagnosis, and better ensure the operation stability and efficiency of solar power station. The performance of photovoltaic combiner box is an important factor in determining the power generation efficiency of photovoltaic power station system. It has the following characteristics: 1. Photovoltaic connection and comprehensive protection scheme are simpler and faster than traditional street light control box; 2. The current and voltage gain expansion capability is strong, and it has stronger adaptability for ultra-long photovoltaic arrays or photovoltaic modules with larger and larger sizes; 3. It has temperature control and fan control, so that it can adapt to application requirements in different environments; 4. Basic protection functions such as lightning protection, reverse voltage protection, circuit fault fuse and lightning protection ensure the safe, reliable and efficient operation of photovoltaic power station.

[0030] However, when external wires are connected to electrical devices, the lack of storage and classification components on the mounting base will make the wires inside the photovoltaic box distributed in a messy manner, making it inconvenient for staff to inspect and maintain them, and also affecting the aesthetics of the interior of the photovoltaic box.

[0031] Based on this, the technical problem in the related art that the internal wires of the photovoltaic box are in a messy distribution and inconvenient for daily inspection and maintenance can be improved, and the embodiments of the present application provide the following solution.

[0032] Please also read Figures 1 to 3 The embodiment of the present application provides a photovoltaic box with wiring classification, including a photovoltaic box body 10, a connecting component 20 and a plurality of limiting components 30, wherein a mounting substrate 11 is movably installed inside the photovoltaic box body 10, a plurality of electrical components 12 are arranged on the mounting substrate 11, and a box door 13 is hingedly connected to the outer wall of the photovoltaic box body 10; the limiting component 30 includes a connecting plate 31, a first clamping plate 32 and a second clamping plate 33, the connecting plate 31 is movably arranged on the mounting substrate 11 through the connecting component 20, the first clamping plate 32 and the second clamping plate 33 are both arranged on the connecting plate 31, a fixing cavity 34 for fixing the pen body is formed between the first clamping plate 32, the second clamping plate 33 and the connecting plate 31, and an end of the first clamping plate 32 away from the connecting plate 31 is abutted against an end of the second clamping plate 33 away from the connecting plate 31.

[0033] From the above, it can be seen that the photovoltaic box with wiring classification provided by the embodiment of the present application, when the staff needs to classify the wires, take the wires of the same type, the first clamp 32 and the second clamp 33 are elastic, pry open the first clamp 32 or the second clamp 33, put the wires of the same type into the fixed cavity 34, loosen the first clamp 32 or the second clamp 33, the first clamp 32 and the second clamp 33 limit the wires of the same type under the action of their own elastic force, the end of the first clamp 32 away from the connecting plate 31 is against the end of the second clamp 33 away from the connecting plate 31, so that the wires of the same type are difficult to leave the fixed box, and other wires of the same type are limited and stored in this way; therefore, the setting of the connecting plate 31, the first clamp 32 and the second clamp 33 makes it convenient for the staff to store the wires and to inspect and maintain them.

[0034] Optionally, in some embodiments, please read Figures 2 to 3 One end of the first clamping plate 32 away from the connecting plate 31 is hinged with a fixing sleeve 35 through a rotating shaft 36. The fixing sleeve 35 includes a fixing plate 351 and a side plate 352. One end of the side plate 352 is rotatably connected to the rotating shaft 36, and the other end is connected to one end of the fixing plate 351.

[0035] With such arrangement, when the staff is sorting the wires, if there are too many wires of the same type, after putting too many wires into the fixing cavity 34, the end of the first clamping plate 32 away from the connecting plate 31 and the end of the second clamping plate 33 away from the connecting plate 31 will move in the direction away from each other, and it is difficult for them to abut against each other, forming an opening, flipping and stretching the fixing plate 351, and the rotating shaft 36 and the elastically arranged side plate 352 rotate, and the side plate 352 is stretched by force until the fixing plate 351 is flipped to the side of the second clamping plate 33 away from the first clamping plate 32, and the fixing plate 351 is released. The fixing plate 351 abuts against the side wall of the second clamping plate 33 under the elastic action of the side plate 352. Therefore, the setting of the fixing sleeve 35 enables the user to block the opening by flipping the fixing sleeve 35 when there are too many wires of the same type, thereby reducing the probability of the wires escaping from the fixing cavity 34 and improving the storage effect of the limiting assembly 30.

[0036] Optionally, in some embodiments, see Figures 2 to 3 A screw rod 37 is rotatably connected to the fixing sleeve 35 , and the screw rod 37 passes through the fixing sleeve 35 .

[0037] With such a configuration, after using the fixing sleeve 35 to block the opening of the limiting assembly 30 formed due to excessive wires, the screw 37 is rotated so that the end of the screw 37 close to the second clamping plate 33 abuts against the side wall of the second clamping plate 33, and the thread is continued to be rotated so that the end of the second clamping plate 33 away from the connecting plate 31 moves toward the direction close to the first clamping plate 32, thereby achieving the effect of reducing the opening gap; therefore, the setting of the screw 37 allows the user to achieve the effect of reducing the opening gap by rotating the screw 37, and makes it difficult for the fixing sleeve 35 to loosen, further reducing the probability of the wire escaping from the fixing cavity 34.

[0038] Optionally, in some embodiments, see Figures 2 to 3 One end of the screw rod 37 away from the rotating shaft 36 is fixedly connected with a knob 38 .

[0039] With such a configuration, after using the fixing sleeve 35 to block the opening of the limit assembly 30 formed due to excessive wires, the knob 38 is rotated so that the end of the screw 37 close to the second clamping plate 33 abuts against the side wall of the second clamping plate 33, and the knob 38 is continued to be rotated so that the screw 37 drives the end of the second clamping plate 33 away from the connecting plate 31 to move toward the first clamping plate 32, thereby achieving the effect of reducing the opening gap; therefore, the setting of the knob 38 makes it convenient for the staff to control the rotation of the screw 37.

[0040] Optionally, in some embodiments, see Figures 2 to 3 The connecting component 20 includes a slide 21 and a plurality of sliders 22 . The slide 21 is disposed on the mounting substrate 11 . The sliders 22 are slidably mounted in the slide 21 . The sliders 22 are connected to the connecting plate 31 .

[0041] With such a configuration, when it is necessary to store the wires at a certain position, the connecting plate 31 is slid, and the slider 22 slides on the slide 21 until the limiting assembly 30 slides to the position where the wires are present, and then the first clamping plate 32 or the second clamping plate 33 is opened to store them; therefore, the configuration of the slide 21 and multiple sliders 22 facilitates the limiting assembly 30 to store the wires at different positions.

[0042] Optionally, in some embodiments, see Figures 2 to 3 The protrusion of the side wall of the slider 22 is slidably fitted with the concave portion of the inner wall of the slideway 21 , and a damping force is provided between the slider 22 and the inner wall of the slideway 21 .

[0043] With such arrangement, when the slider 22 is slid, the raised part of the side wall of the slider 22 slides and fits with the depressed part of the inner wall of the slide 21, making it difficult for it to loosen, thereby increasing the stability of the connecting component 20; when the slider 22 is in a stationary state, a damping force is provided between the slider 22 and the inner wall of the slide 21, making it difficult for it to shake, thereby making it convenient for personnel to control the sliding position of the upper limit component 30 on the slider 22. When the staff performs subsequent maintenance on the wires, the slider 22 is not easy to shake under the action of the damping force, thereby facilitating the maintenance operations of the staff.

[0044] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
