[0002] In the field of network transformers, the main components of the product include metal PIN, base and coil. The three components are assembled to form a functional product. The metal PIN on the internal components of the product is inserted into the base or the metal PIN and the base are injection molded to form a module; then the lead of the coil is wrapped around the metal PIN of the module, and then the lead and the metal PIN are connected and connected by forming a welding point by tinning. Among them, one or more leads of each coil need to be wrapped around a common metal PIN at the same time, and the remaining leads of each coil will be wrapped around their corresponding single metal PINs respectively, and the leads wrapped around the common metal PIN will have many leads at the same time.
