AI Technical Summary
Traditional photovoltaic system connector protective shells have insufficient sealing performance, poor environmental adaptability, and are prone to exacerbating malfunctions due to moisture intrusion, thus affecting system safety.
A fire-resistant housing for photovoltaic cables was designed, comprising a main housing, a secondary housing, a sealing block, a sealing strip, a buckle, and a positioning post. The housing achieves sealing and fixation through the cooperation of multiple structures, and, combined with fireproof stickers, releases extinguishing agents at high temperatures to prevent the spread of fire.
The connector's sealing performance has been improved, its environmental adaptability has been enhanced, moisture intrusion has been prevented, malfunctions have been effectively prevented, and it automatically extinguishes fires at high temperatures to ensure system safety.
