The manufacture of connectors can be generally divided into four stages: stamping, electroplating, injection molding and assembly.
The manufacturing process of electronic connectors generally begins with a stamped pin. Through large-scale high-speed punches, electronic connectors (pins) are stamped from thin metal strips. One end of the large-volume metal belt is fed into the front end of the punching machine, and the other end is wound into the reeling belt through the hydraulic workbench of the punching press. The metal belt is pulled out by the reeling belt and rolled up to punch out the finished product.
After the connector pin stamping is complete, it should be sent to the plating section. At this stage, the connector's electronic contact surface will be plated with various metal coatings.
3, Injection molding
The plastic connector of the electronic connector is made during the injection molding stage. The usual process is to inject the molten plastic into the metal film and then rapidly cool it.
The final stage in the manufacture of electronic connectors is assembly of finished products. There are two ways to connect the plated pins with the injection box seats: separate plug or combination plugs. Individual plugging refers to inserting one pin at a time; a combined plug inserts multiple pins at the same time with the cassette holder. Regardless of the type of patching method used, manufacturers are required to detect all pins in the assembly stage for missing and correct positioning. Another type of routine inspection task is related to the measurement of the spacing on the mating surface of the connector.
