1.What is a connector  
Electronic connector refers to the connection unit between various electronic components, mainly as chip to circuit board, circuit board and circuit board to box electronic signal connection and transmission.  Type, can be divided into substrate connector, angular connector, cylindrical connector, and the popular PCMCIA specifications connector and so on.  
Although the definition of electronic connectors has not been very clear, the scope of their coverage, the general understanding does not include power plugs or sockets other than high voltage, high current appliances or electrical connectors: electrical switches are not included in the large.  In Most industries in Japan, people use the transliteration of English (Connector) directly, sometimes called "continuous parts". In Mainland China, people use "electric plug" or "electric plug", including Connector and switch, regardless of the broad term of electronic and electrical appliances.  In terms of applications, most electronic connectors are used in computers, telecommunications, aviation, automobiles and various instruments.  

2. Connector application  
Electronic connectors are used in electrical products, as the name implies they act as electronic numbers.  Or component connection, is a kind of multiple integration or assembly of products, and cover metal sheet, surface plating, precision machining and plastic molding and other key technologies.  As the transmission and connection of electronic numbers, if there is a problem with the electronic connector, it will lead to the failure of electronic components or even the entire equipment.  The whole connector includes terminal and plastic two main parts, the terminal part in addition to the selection of materials, electroplating and die will affect the quality of the product, of course, the plastic part is the same truth.  
3. Connector manufacturing  
Electronic connector manufacturing from design to finished products, can be divided into metal and plastic two parts.  In addition to the selection of materials for metal parts, electroplating and die for the main work;  Mold work is mold design, mold opening, injection molding, and then with metal assembly into electronic connectors.  Electronic connectors are used in electrical products. As the name implies, they are the connections of electronic signals or components. They belong to a variety of integrated or assembled products, and cover metal sheet, surface plating, precision machining and plastic molding and other key technologies.  As the transmission and connection of electronic signals, if there is a problem with the electronic connector, it will lead to some parts in addition to the selection of materials, electroplating and stamping die will affect the quality of the product, of course, the plastic part is the same way its manufacturing includes five technologies :1.  Die technology.2. Injection molding technology. 3. Electroplating technology.4. Assembly technology. 5.  Due to the trend of the connector to the thin short and SMT, therefore, the manufacturing technology of required also need speed to improve the precision of demand, at the same time for makers of precise ideas also change need to produce precision connector, or in the late of the connector for market, will be eliminated, due to quality cannot be competitive electronic components and even whole equipment failure.  The whole connector includes two main parts: terminal and plastic terminal.
