  • Patent number: 11418147
    Abstract: An integrated photovoltaic cable having a connecting terminal and a housing injection-molded on the connecting terminal. The connecting terminal has a connecting sheet, a through hole, and a plurality of U-shape groove sheets. Exposed conductors obtained by peeling front ends of the photovoltaic cable are respectively placed into corresponding U-shape groove sheets and crimped by a crimping plier. A manufacturing method for manufacturing the integrated photovoltaic cable includes three steps of manufacturing a connecting terminal, crimping photovoltaic wires, and injection molding a housing. An improvement of the cable connecting structure simplifies the production, improves the connecting quality, and reduces a volume of an adapter. The conductor end and the U-shape groove are firmly and conveniently connected to ensure the connection quality, reduce a contact resistance of a connecting wire, and cause a smaller volume of the adapter.
