Connectors are a component that electronic engineers and technicians often come into contact with. Its function is very simple: to build a bridge 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 integral part of electronic equipment. If you follow your current path, you will always find one or more connectors. The form and structure of connectors are ever-changing. There are various types of connectors depending on the application system, frequency, power and application environment. For example, the connectors used for lighting on the court are very different from those used for hard drives. However, no matter what kind of connector it is, it is necessary to ensure that the current flow is smooth, continuous and reliable.
