The production and manufacturing of Guangjiayuan Electronic USB connectors can be divided into two parts: metal materials and plastics, from design solutions to finished products. In addition to using raw materials, electroplating and stamping molds are key tasks in the metal material part; At the mold level, the work involves designing the mold, producing the mold, shooting it into shape, and then combining metal material components to form electronic USB connectors. Guangjiayuan electronic connectors are used in electrical products, playing the role of electronic signal or component connections, belonging to a diversified combination or assembly of goods, and covering core technologies such as copper sheets, surface electroplating, precision mechanical processing, and plastic molding

As the transmission and connection of electronic signals, if there are problems with electronic USB connectors, it will cause partial damage to the quality of the product, except for the use of raw materials. The quality of electroplating and stamping molds will also be affected, and the production and manufacturing of natural plastics also involve four major technical aspects:

1. Stamping stamping is to press Electrical connector (contact pin) from thin metal strip by large high-speed stamping machine. One end of the large roll of metal strip is fed into the front end of the stamping machine, and the other end passes through the hydraulic workbench of the stamping machine and is wrapped in a winding wheel. The winding wheel pulls out the metal strip and rolls it up to punch out the finished terminal.

2. After the stamping of the electroplating connector pins is completed, they should be sent to the electroplating stage. During the electroplating stage, the electronic contact surface of the connector will be coated with various metal coatings, including nickel plating, tin plating, and semi gold plating to prevent oxidation and enhance conductivity. Pins may also experience distortion, fragmentation, or deformation during the process of feeding stamped pins into electroplating equipment. And these quality defects are easily detected through the above techniques.

3. Molding refers to the plastic box seat of Electrical connector, which is made by injecting molten plastic into the metal mold, and then rapidly cooling and forming. Also pay attention to detecting whether there is a "leak" when the melted plastic is not fully filled with the fetal membrane; (ShortShortShorts), this is a typical defect that needs to be detected during the injection molding stage. Other defects include the filling or partial blockage of the socket (these sockets must be kept clean and unobstructed in order to properly connect with the pins during final assembly).

4. The final stage of Electrical connector manufacturing is finished product assembly. There are two ways to connect and assemble the electroplated pins with the injection box seat: the first is to insert them separately, which refers to inserting one pin at a time; The second type is combination and insertion, which refers to the simultaneous insertion of multiple pins into the box base at once. Regardless of the insertion method used for assembly, it is important to ensure that all pins are not missing or positioned correctly.

USB connector is applicable to all electronic goods: for example, industrial production electronics, consumer electronics, shipbuilding, electronic communications, diagnosis and treatment or transportation facilities engineering. The course content focuses on specific applications, including raw materials, basic theories of connection and Electronic engineering projects, as well as various connection technologies used for circuit boards and cables, The reason for incorrect regulations on standard detection and different types of USB connectors.
