TECHNICAL FIELD

The present disclosure relates to the technical field of photovoltaic connectors, in particular to a photovoltaic connector with good contact performance.

BACKGROUND

At present, most of the male and female terminals of photovoltaic connectors have a stamping and round forming structure. A conductive internal network is assembled in a female terminal as a conductive transmission medium. When being inserted, the male terminal is in contact with the conductive internal network, and at the same time, the male terminal presses the conductive internal network. The conductive internal network is in contact with the inner wall of the female terminal, thus realizing power transmission. Medium transmission increases the unreliability of contact. For example, poor contact may lead to excessive local temperature rise, so that insulating parts of photovoltaic connectors are burned, resulting in the burning of photovoltaic connectors and power generation loss of the power station. At the same time, medium transmission increases contact impedance, which in turn increases power generation loss and reduces power output, thus affecting the overall installed capacity of the power station.
