Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel wiring equipment, specifically a solderless photovoltaic panel wiring device. Background Technology

[0002] When photovoltaic panels are connected to electricity, a corresponding controller needs to be installed to convert solar energy into electrical energy. The controller is a transitional component, and it is basically welded to the base that supports the photovoltaic panels through a mounting bracket. However, if this type of welding installation method is used, it is not easy to disassemble, repair or replace the solar controller when there is a problem.

[0003] According to a patent document with publication number CN221862799U, a welding-free photovoltaic panel wiring device is disclosed, which includes a base plate. Several equally sized pads are mounted on the upper end of the base plate at a distance of no more than three centimeters from the edge. A common frame is welded to the upper surface of the pads. The frame, pads, and base plate form a base structure. A photovoltaic panel is embedded in the inner wall of the frame. A positioning frame is fitted to the lower end of the base plate along its longitudinal central axis. The two side walls of the positioning frame are fixed by screws. In use, the lifting plate inside the positioning frame moves up and down via a threaded rod and threaded sleeve, thereby adjusting the cable tray with a strip structure. The cable tray can be tightly fitted to the inner wall of the positioning frame. Multiple wires that pass through and connect to the solar panel can be arranged side-by-side inside the cable tray, preventing tangled wires. While this solution achieves cable management, it cannot limit and fix one end of the cable, causing inconvenience in use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a solderless photovoltaic panel wiring device to solve the problems mentioned in the background. This utility model has a novel structure. In use, one end of the cable is installed between the extrusion column and the electrode column through a movable seat. The extrusion column squeezes the cable to quickly limit its installation at one end of the electrode column to achieve circuit connection. Later, the cable can be quickly disassembled from the inside of the sealed joint by separating the extrusion column and the electrode column.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solderless photovoltaic panel wiring device, comprising a photovoltaic panel, a fixed base fixed to the side of the photovoltaic panel, a movable base movably mounted on the fixed base, a sealing joint fixed to the side of the movable base, a cable movably mounted on the sealing joint, a limiting plate movably mounted on the movable base, a protrusion fixedly mounted to the side of the limiting plate, a fixing groove formed on the fixed base, a limiting frame movably mounted inside the fixing groove, and a limiting block fixed to the side of the limiting frame.

[0006] Furthermore, a fixing block is welded to one end of the limiting frame, and a connecting groove is opened on the movable seat, with the limiting frame movably installed inside the connecting groove.

[0007] Furthermore, the movable seat has a fixing hole, and a tension mechanism is fixed inside the fixing hole. One end of the tension mechanism is fixed with a fixing column.

[0008] Furthermore, one end of the fixed column is fixed to the limiting plate, the limiting plate is fixed with an extrusion column, the movable seat has a positioning hole, and the extrusion column is movably installed inside the positioning hole.

[0009] Furthermore, an electrode post is fixed on the fixed base, and an opening is made at the bottom of the movable base, through which the electrode post contacts one end of the cable.

[0010] Furthermore, a support spring is fixed inside the limiting groove, a limiting block is fixed to one end of the support spring, and one end of the limiting block is fixed to the limiting frame.

[0011] The beneficial effects of this utility model are:

[0012] 1. In this solderless photovoltaic panel wiring device, one end of the cable is installed between the extrusion column and the electrode column through a movable seat during use. The extrusion column squeezes the cable to quickly limit its installation at one end of the electrode column to achieve circuit connection. Later, the cable can be quickly disassembled from the inside of the sealed joint by separating the extrusion column and the electrode column.

[0013] 2. In this solderless photovoltaic panel wiring device, a limiting frame is installed on a movable seat to limit and fix the movable seat. The limiting plate limits and fixes the cable and the limiting frame at the same time through the extrusion column, thereby preventing the limiting frame from moving up and down and causing loosening between the movable seat and the fixed seat.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a solderless photovoltaic panel wiring device, including a photovoltaic panel 1, a fixed base 2 fixed to the side of the photovoltaic panel 1, a movable base 3 movably mounted on the fixed base 2, a sealing joint 5 fixed to the side of the movable base 3, a cable 6 movably mounted on the sealing joint 5, a limiting plate 4 movably mounted on the movable base 3, a protrusion 7 fixedly mounted on the side of the limiting plate 4, a fixed groove 8 opened on the fixed base 2, a limiting frame 10 movably mounted inside the fixed groove 8, a limiting block fixed to the side of the limiting frame 10, a fixing block 14 welded to one end of the limiting frame 10, a connecting groove 13 opened on the movable base 3, and the limiting frame 10 movably mounted inside the connecting groove 13. The protrusion 7 facilitates the up-and-down movement of the limiting plate 4, and the rising of the limiting plate 4 facilitates the subsequent disassembly of the movable base 3.

[0021] In this embodiment, the movable seat 3 has a fixing hole 16, and a tension mechanism 17 is fixed inside the fixing hole 16. A fixing post 12 is fixed to one end of the tension mechanism 17, and one end of the fixing post 12 is fixed to the limiting plate 4. A pressing post 11 is fixed to the limiting plate 4. The movable seat 3 has a positioning hole, and the pressing post 11 is movably installed inside the positioning hole. An electrode post 15 is fixed to the fixed seat 2. An opening is opened at the bottom of the movable seat 3, and the electrode post 15 contacts one end of the cable 6 through the opening. A support spring is fixed inside the limiting groove 9, and a limiting block is fixed to one end of the support spring. One end of the limiting block is fixed to the limiting frame 10. The tension mechanism 17 is a tension spring, which drives the limiting plate 4 to move downward. The downward movement of the limiting plate 4 causes the pressing post 11 to press and fix one end of the cable 6.

[0022] In use, after the photovoltaic panel 1 is fixedly installed, the cable 6 is connected to the photovoltaic panel 1. During installation, the limiting plate 4 is moved upward via the fixing column 12. After the limiting plate 4 moves upward, the fixing column 12 is pulled upward, and the cable 6 is installed inside the movable seat 3 through the sealing connector 5. After the cable 6 is installed, the limiting frame 10 is moved upward inside the fixing groove 8, and one end of the fixing block 14 is moved to the top of the movable seat 3. When the movable seat 3 is installed on the fixed seat 2, the electrode column 15 is installed inside the movable seat 3 from the bottom. After the movable seat 3 is installed on the fixed seat 2, the limiting frame 10 enters the connecting groove 13. Inside, the movable seat 3 is installed on the fixed seat 2 by the downward pulling force of the limiting frame 10. Then the limiting plate 4 is released and moves downward. The limiting plate 4 moves to the top of the limiting frame 10. Under the pull of the pulling mechanism 17, the extrusion column 11 enters the interior of the movable seat 3. The extrusion column 11 and the electrode column 15 cooperate to complete the extrusion and fixation of one end of the cable 6, thereby realizing the quick installation and connection of the cable 6 and the electrode column 15. Later, when it is necessary to disassemble the cable 6, the limiting plate 4 rises to limit the movable seat 3. The electrode column 15 and the extrusion column 11 separate from the cable 6 at the same time, and the cable 6 can be quickly disassembled from the inside of the sealing joint 5.
