In the photovoltaic power generation system, to collect the power of a large number of components and enter the inverter, you must rely on cables and connectors. Photovoltaic connectors are components, combiner boxes, controllers and inverters in the photovoltaic power generation system. The critical parts that connect components to each other.

Since photovoltaic systems are exposed to wind, rain, hot sun and extreme temperature changes for a long time, the application environment of connectors is also very harsh. The requirements are not only waterproof, high temperature resistance and UV weather resistance, but also touch protection and high current carrying capacity. Therefore, there are extremely high process requirements for photovoltaic connectors and their internal components.
Pins and sockets: photovoltaic connectors are divided into male ends and female ends, and conductive terminals are provided inside. The internal conductive terminals are generally divided into pins and sockets. The sockets realize mutual electrical connection.
Photovoltaic collar: Set in the connector housing, it is used to cooperate with the backstop structure of the conductive terminal to realize the axial limit function of the conductive terminal. Stability between conductive terminals and male or female housings.
