are basically cables with multiple copper wires. The connection method of the solar cables and metal terminals and the quality of the connection will affect the long-term safety of the solar connector. It is necessary to ensure that all copper wires are Complete and tight packaging, which puts forward strict requirements on the specifications of the cable, the size of the terminal crimping part, and the crimping process. Once there is a condition that does not match, there may be exposed copper wires . Or the phenomenon that the crimping part is missing . In addition to relying on visual inspection to identify, the introduction of compression ratio can also more intuitively inspect the quality of crimping, and avoid the safety hazards caused by such internal connection problems during the long-term use of the product.
The determination of the rated current is also very important. If the solar connector is exposed to a current exceeding its own current-carrying capacity for a long time, it will accelerate the aging of materials and accessories and shorten its service life. Therefore, understanding the performance of various parts such as the cables, metal terminals and shell materials of the connector, and matching them in a targeted manner, can largely avoid the risk of blindly upgrading the current of the connector.
