The electronic connector generally refers to the connection unit between various electronic components, mainly used as the connection and transmission of electronic signals from chip to circuit board, between circuit boards and circuit board to box

In terms of category, it can be divided into substrate connector, angle connector, cylindrical connector, and the popular PCMCIA specification connector

Although the definition of electronic connector is still unclear, its scope does not include high voltage and high current electrical appliances or electrical connectors other than power plugs or sockets; electrical switches also do not include large electrical connectors In Japan, most people in the industry directly use the transliteration of connector, sometimes called "continuous piece", while in Chinese Mainland, they use "electrical plug" or "electrical plug", including connectors and switches, regardless of electronics and appliances In terms of application, most electronic connectors are used in computers, telecommunications, aviation, automobiles and various instruments

As the trend of connectors tends to be thin, short and SMT, the required manufacturing technologies also need to improve their accuracy requirements rapidly. At the same time, the precision concept of manufacturers has also changed so that precise connectors can be manufactured. Otherwise, in the future market of connectors, they will be eliminated, because the quality cannot compete with electronic components or even the entire equipment fails. The entire connector includes terminals and plastic terminals
