The connector is a part of the circuit that connects multiple solar cell modules to the system. It can also be said that it is a more formal terminal or quick connector, which can be plugged and unplugged at any time.

      Connectors are components frequently contacted by our electronic engineering and technical personnel. Its function is very simple: it builds a bridge of communication between the blocked or isolated circuits in the circuit, so that the current can flow, and the circuit can realize the predetermined function. Connectors are an indispensable part of electronic equipment. Looking along the path of current flow, you will always find one or more connectors. The form and structure of connectors are ever-changing. There are many types of connectors, with different application objects, frequencies, power, and application environments. For example, the lighting connector and hard drive connector on the stadium, and the rocket lighting connector are quite different. But no matter what kind of connector, it must ensure that the current flows smoothly, continuously, and reliably. Generally speaking, what the connector is connected to is not limited to current. In today's rapid development of optoelectronic technology, in the optical fiber system, the carrier of the signal is light. Glass and plastic replace the wires in ordinary circuits, but optical signal connectors are also used in pathways, and their functions are the same as circuit connectors.
