Technical Field
[0001] This utility model relates to the field of photovoltaic junction box technology, and in particular to a solar street light direct-plug locking junction box. Background Technology
[0002] A solar photovoltaic (PV) panel is a photoelectric device that converts solar energy into light energy. Internally, it collects the generated electrical energy on positive and negative electrodes through parallel or series connections, and provides power to the outside through an external circuit. The junction box acts as a bridge between the PV panel and the external circuit. On the one hand, it connects the PV panel electrodes and encapsulates them on the PV panel. On the other hand, the junction box uses terminals and connectors to lead out the current generated by the solar module and guide it into the electrical equipment.
[0003] However, current photovoltaic junction boxes require the lead wires to be routed out from inside the box and connected to male connectors after internal wiring is soldered, followed by connection with corresponding female connectors, which is a cumbersome process. Therefore, those skilled in the art have provided a direct-plug locking junction box for solar streetlights to solve the problems mentioned in the background section. Utility Model Content
