Although there are various types of connectors, the large majority are one-piece types that are used alone or two-piece types consisting of a plug and socket. One-piece types directly connect printed circuit boards and wires to connectors.
Two-piece types are divided into plug and socket, the part where the plug and the socket are fitted is called the contact part, and the part where the printed circuit board or the electric wire is attached is called the connection part.
