What is a connector? Connectors are also commonly called circuit connectors. As the name implies, it is a conductor device that bridges two conductors in a circuit so that current or signal can flow from one conductor to the other. Electronic connector is a kind of motor system, which can provide a separable interface to connect two sub-electronic systems. Simply put, the components used to complete the electrical connection between circuits or electronic machines are called connectors, that is, bridges between them. Classification of connectors Positioning connectors for electronic circuits consist of plug-ins and connectors (such as charging connectors and plugs). Common connectors usually include the following two parts. 1. Terminal (terminal for short) is made of metal and plays a conductive role. In order to facilitate the connection of wires, there are holes at both ends for inserting wires. 2. The terminal shell is referred to as rubber shell for short, mostly plastic, which plays a protective role. It is the nail of the terminal and is used together with the terminal. The uses of connectors range from televisions and computers to medical devices, aviation and military, and an indispensable connector is hidden in many high-tech products.
