I. What is a connector
Electronic connectors generally refer to the connecting units between various electronic components, primarily serving as a means for signal connection and transmission between chips and circuit boards, between circuit boards, and from circuit boards to enclosures. In terms of types, they can be divided into connectors for circuit boards, angular connectors, cylindrical connectors, as well as the increasingly popular PCMCIA specification connectors, among others.
Although the definition of electronic connectors has always been unclear, the general understanding of their scope does not include high-voltage, high-current electrical appliances or electrical connectors other than power plugs or sockets, nor does it include electrical switches. In Japan, most industry professionals directly use the transliteration of the English word "Connector", sometimes called "continuous piece". In Chinese Mainland, "electrical connector" or "electrical connector assembly" is used, encompassing connectors and switches, and is a broad term that does not distinguish between electronics and electrical appliances. In terms of application, most electronic connectors are used in computers, telecommunications, aviation, automotive, and various instruments.
II. Application of connectors
Electronic connectors are used in electrical products, as the name suggests, they serve as connectors for electronic components or assemblies. They are a type of multi-component or assembled product, incorporating key technologies such as metal sheet covering, surface plating, precision machining, and plastic molding. As the transmission and connection of electronic signals, if there is a problem with the electronic connector, it can lead to the failure of electronic components or even the entire device. The entire connector consists of two main parts: the terminal and the plastic. In addition to material selection, the quality of plating and die-casting in the terminal part can affect the product quality, and the same goes for the plastic part.
III. Manufacturing of connectors
The manufacturing of electronic connectors, from design to finished product, can be divided into two parts: metal and plastic. For the metal part, besides material selection, electroplating and die-casting are the main processes; for the plastic part, the work involves plastic mold design, mold opening, injection molding, and then assembly with metal components to form an electronic connector. Electronic connectors are used in electrical products, and as the name suggests, they play the role of connecting electronic signals or components. They are a type of multi-component or assembled product, incorporating key technologies such as metal sheet covering, surface electroplating, precision machining, and plastic molding. As the transmission and connection of electronic signals, if there is a problem with the electronic connector, it will affect the quality of the product, just as the quality of the materials selected, the quality of electroplating and die-casting will affect the product quality. Of course, the plastic part follows the same principle. Its manufacturing includes five major technologies: 1. Die-casting technology, 2. Injection molding technology, 3. Electroplating technology, 4. Assembly technology, and 5. Testing technology. Due to the trend of connectors becoming thinner, shorter, and smaller, as well as SMT-oriented, the required manufacturing technologies also need to rapidly improve their precision requirements. At the same time, manufacturers must have a precise concept to produce precise connectors, otherwise they will be eliminated from the connector market in the future due to quality issues that make electronic components or even the entire equipment fail. The entire connector includes two main parts: terminals and plastic.
