Technical Field

[0001] This utility model relates to the field of junction box technology, and more specifically, to a four-segment photovoltaic junction box. Background Technology

[0002] The four-segment photovoltaic junction box is a circuit protection and connection device specifically designed for high-efficiency, high-power photovoltaic modules. Its core function is to improve the safety, power generation efficiency, and maintenance convenience of the modules through segmented management and independent protection. Among them, the diode is the core protection component in the photovoltaic system. Its core function is to achieve circuit protection, efficiency optimization, and stable system operation through unidirectional conductivity and reverse breakdown characteristics.

[0003] During the wiring process of a four-section photovoltaic system, wiring installation needs to be carried out inside the box. However, since each section has multiple positions during installation and use, it is difficult to position and insulate between these positions. This can easily lead to section misalignment later on, significantly reducing the insulation stability of the sections. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 present utility model.

[0018] like Figure 1 - Figure 4 The diagram shows a four-segment photovoltaic junction box, which is equipped with an insulation positioning component. The insulation positioning component can significantly improve the stability of the positioning insulation when the photovoltaic wiring is used. The specific structure of the insulation positioning component is as follows.

[0019] In this embodiment, as Figure 1 - Figure 3 As shown, the insulating positioning assembly includes: multiple insulating blocks 3 symmetrically arranged on both sides of the connecting piece 2; an insulating strip 4 is installed at one end of the connecting piece 2; both the insulating strip 4 and the insulating blocks 3 are used for insulating positioning of the connecting piece 2, and both the insulating strip 4 and the insulating blocks 3 are fixedly connected to the housing 1; a mating piece 5 fixed to the other end of the connecting piece 2; a first diode 6 installed at one end of the mating piece 5, and a copper sheet 7 fixedly installed at one end of the first diode 6; a side insulating block 8 slidably installed on one side of the outer wall of the copper sheet 7; an end insulating block 9 is installed on the outer wall of the copper sheet 7 adjacent to the side insulating block 8; both the copper sheet 7 and the mating piece 5 are slidably connected to the end insulating block 9. The inner walls of the insulating strip 4 and the insulating blocks 3 are rounded, and both the insulating strip 4 and the insulating blocks 3 are made of plastic. The upper surfaces of the end insulating block 9 and the side insulating block 8 are rounded, and the outer walls of the end insulating block 9 and the side insulating block 8 are smooth surfaces.

[0020] In this embodiment, as Figure 3 As shown, a bottom insulating block 10 is installed on the lower surface of the copper sheet 7, and the bottom insulating block 10 is fixedly connected to the housing 1; the bottom insulating block 10 is used to provide insulating support for the copper sheet 7. In order for the housing 1 to support the bottom insulating block 10, the bottom insulating block 10 is positioned and insulated in the lower surface area of ​​the copper sheet 7, thus ensuring that the lower surface of the copper sheet 7 forms a positioning insulation operation.

[0021] In use, the four-segment photovoltaic junction box of this technology guides the connecting piece 2 to be installed on the inner wall of the insulating strip 4. Two insulating blocks 3 provide positioning insulation for both sides of the connecting piece 2, and the insulating strip 4 provides positioning insulation for the end of the connecting piece 2. Simultaneously, the other end of the copper sheet 7 is positioned and insulated by a side insulating block 8 to create a gap between the copper sheet 7 and the mating piece 5. An end insulating block 9 provides positioning insulation for the gap between the copper sheet 7 and the mating piece 5 at the side of the copper sheet 7. The box body 1 supports a bottom insulating block 10, which provides positioning insulation on the lower surface area of ​​the copper sheet 7. After photovoltaic wiring, the second diode 11 is energized through the connecting piece 12, which in turn energizes the connecting piece 2, which in turn energizes the mating piece 5, which in turn energizes the first diode 6. The first diode 6 then energizes the copper sheet 7, allowing the copper sheet 7 to connect with other wire harnesses to form a series power supply circuit. This results in higher insulation stability during photovoltaic wiring.

[0022] In this embodiment, as Figure 1 - Figure 4 As shown, a second diode 11 is fixedly installed on the outer wall of the connecting piece 2 near the insulating block 3, and a connecting piece 12 is fixedly connected to one end of the second diode 11. Two positioning posts 13 are inserted into the inner wall of the connecting piece 12, and a reinforcing block 14 is fixed to the bottom of each positioning post 13. Both reinforcing blocks 14 are fixedly connected to the housing 1. The top diameter of the positioning post 13 is smaller than the bottom diameter, and the outer wall of the positioning post 13 is a smooth surface. The reinforcing block 14 is used to make the positioning post 13, and the positioning post 13 is made of plastic.

[0023] In use, the four-segment photovoltaic junction box of this technology supports the second diode 11 through the connecting piece 2, the second diode 11 supports the connecting piece 12, and the box body 1 supports the reinforcing block 14, which in turn supports the positioning post 13. In this way, the positioning post 13 guides and positions the connecting piece 12, ensuring that the connecting piece 12 can be stably guided and greatly improving the stability of the positioning and insulating connecting piece 12.
