A pin connector, also known as a pinhole connector, is an electrical connector that is connected by means of several metal pin-like plugs and sockets with pinholes in them. It is widely used in electronics, communications, aerospace and other fields, and has the advantages of simple structure, reliable contact, easy to use and so on. This article will analyse and introduce the composition, classification, characteristics and applications of pin connector connectors.Pin Header Connector
A. Composition
Pin connector connectors are composed of plugs, sockets and terminals, where plugs and sockets are installed in different devices and connected to each other by connecting wires or terminals on the PCB board. The plug is usually fixed with several metal pin plugs, while the socket has the same number of metal pin eyes corresponding to the plugs on the plug. When the plug is inserted into the socket, the metal plug comes into contact with the pinhole in the socket and makes the electrical connection.Female Header Connector
II. Classification
Pin connector connectors can be divided into various types according to the electrical nature, structural form and use of different aspects. According to the electrical nature can be divided into power type, signal type, hybrid type and high-speed type, etc.. According to the structure form can be divided into round, rectangular, bayonet type and SMT, etc. According to the use can be divided into different types needed in many fields such as medical, communication, military aviation, automotive and robotics.Female Header Connector
