Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation equipment, in particular to a fixing mechanism of a solar energy and mains electricity complementary photovoltaic controller. Background Art

[0002] Photovoltaic controller is an automatic control device used in solar power generation system to control multiple solar cell arrays to charge batteries and batteries to supply power to solar inverter loads. Photovoltaic controller uses high-speed CPU microprocessor and high-precision A / D analog-to-digital converter, and is a microcomputer data acquisition and monitoring control system; traditionally, this system is installed on the wall through its shell. The inconvenience of this installation method is that the whole machine needs to be removed from the wall when maintenance is needed later. This will cause the wall opening and the expansion tube of the screw to loosen and cannot be fixed during removal and installation. In addition, after the photovoltaic controller is installed, the wires dragged below it are all connected to the terminal. Because the connection point is only connected by screw compression, the connecting wire is fragile and it is easy to fall off and disconnect due to the gravity of the wire. In order to solve these problems, we propose a fixing mechanism for solar-to-city-electricity complementary photovoltaic controller. Utility Model Content

[0022] It should be noted that the utility model is a fixing mechanism for a solar-to-mains-electricity complementary photovoltaic controller. During installation, the wall fixing structure 5 is fixed to the expansion tube preset on the wall through the expansion screw through the mounting hole 505. After fixing, a thin layer of thermal conductive silicone grease is first applied to the heat dissipation contact plate 601. Then, the heat dissipation back plate 2 behind the control body 1 only needs to be slightly squeezed to bring the front surface of the heat dissipation contact plate 601 close to the upper end, so that the card strips 201 on both sides are embedded in the card slot 503, and then slide along the card slot 503 to the bottom to be fixed. After fixing, the heat dissipation contact plate 601 is tightly pressed against the rear surface of the heat dissipation back plate 2 by the extrusion force of the reset spring 604, thereby achieving close contact heat conduction and heat The distribution function is provided. If the control body 1 needs to be disassembled later, it can be disassembled by simply pulling it upwards. After installation, the wires near the connection end are knotted, and a sufficient length of wire is reserved between the end and the knot. The purpose is that when the wires are pulled or stressed by the outside world, the knotted part will be stuck on the upper surface of the upper clamping plate 404 and the bottom clamping plate 401 and will not cause stress on the wires above the knot, thereby preventing the connection from falling off. Then the connected wires will be knotted above the bottom clamping plate 401 and clamped into the lower clamping groove 402. After the wires are clamped in, the upper clamping plate 404 is closed so that the upper clamping groove 405 clamps the wires, and then the spiral button 406 is screwed into the screw hole 403 to fix it, thereby completing the installation.
