Description

Technical Field

[0001] The utility model relates to the field of photovoltaic adapters, in particular to a novel cable connector structure. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of operation: independent operation and grid-connected operation. Photovoltaic modules are composed of solar cells or solar cells of different specifications cut by laser cutting machines or steel wire cutting machines. Because the current and voltage of a single solar cell are very small, we first connect them in series to obtain high voltage, and then connect them in parallel to obtain high current before connecting them to the grid.

[0003] Photovoltaic modules usually need to be connected in series through cables. In the prior art, the positive and negative connectors of the cables used to connect photovoltaic modules in series cannot be fixed during use. The positive and negative connectors of the cables are always exposed to the sun and rain outside the modules due to the lack of fixing measures. If the positive and negative connectors of the cables are not fully plugged in, water may easily enter the connectors and the contact may be poor, resulting in safety hazards such as failure to generate electricity, leakage, and short circuit in the photovoltaic modules. To this end, we propose a new cable connector structure to solve the above problems. Utility Model Content
