Description

Technical Field

[0001] This utility model relates to the field of connector structural design, specifically to a new quick-connect photovoltaic connector. Background Technology

[0002] An inverter is a converter that transforms direct current (DC) power into alternating current (AC) power with fixed frequency and voltage or adjustable frequency and voltage. During the conversion process, a safe and reliable connection method is required internally to transmit and regulate electrical energy; this is where connectors play a crucial role. After years of development, the performance and reliability of connectors have greatly improved. However, current connectors on the market still have the following shortcomings: they are difficult to operate and relatively expensive. For example, patent CN108933566B discloses a horizontally split junction box, including a frame, a cover plate, a nylon base plate, terminals, and diodes. The frame is horizontally elongated. The cover plate is detachably fixed to the top of the frame, the nylon base plate is detachably fixed to the bottom of the frame, and the terminals are fixed to the nylon base plate. The terminals are two horizontally arranged and adjacent metal pieces. One horizontal end of the terminal has a busbar connection part, and the other horizontal end has a diode connection part. The two terminals are staggered to form a horizontal elongated shape with a gap between them. The busbar connection parts of the two terminals are horizontally adjacent, and the diode connection parts of the two terminals are horizontally adjacent. The diodes are connected to adjacent diode connection parts. The connectors configured in this junction box require soldering during assembly, making rapid assembly impossible when installing outdoors. Summary of the Invention
