A connector is also often referred to as a circuit connector, which, as the name suggests, is a conductor device that Bridges two conductors on the circuit so that current or signal can flow from one conductor to another. An electronic connector is a motor system that provides a separable interface to connect two sub-electronic systems. In simple terms, the components used to complete the electrical connection between circuits or electronic machines are called connectors, which is the bridge between them. The positioning connector of a link electronic circuit consists of two parts: a plug-in and a connector (such as a charging connector and a plug). Common connectors usually include the following two parts. 1. The terminal (terminal) is referred to as the terminal, which is made of metal and plays a conductive role. In order to facilitate the connection of the wire, there are holes at both ends for inserting the wire. 2. The terminal shell is referred to as the rubber shell, mostly plastic, which plays a protective role and is the nail of the terminal, which is used with the terminal. The use of connectors from TV, computers to medical devices, aviation, military, many high-tech products are hidden in an indispensable connector.
