Description

A network transformer and a wire-hanging method of the network transformer

technical field

The invention belongs to the technical field of transformers, and in particular relates to a network transformer and a wire-hanging method of the network transformer.

Background technique

The lead wire of the magnetic coil of the traditional network transformer is connected to the pin needle by winding. There is a gap for winding wire at the terminal of the pin needle. After the wire winding is completed, the coil lead wire is connected to the pin pin of the shell by hand dipping tin to make it electrically conductive. This kind of process is complicated, the production process is cumbersome, and the operation is difficult. In the process of winding the wire, it is necessary to control the tightness of the coil lead wire; since the lead wire of the magnetic coil is enameled wire, the part of the tool used for winding the wire that is in contact with the enameled wire needs to be polished Smooth, so that the enameled wire will not be damaged during the winding process. If the enameled wire is damaged, it will cause high voltage failure. If the tool used (for example: tweezers) is too sharp, the lead wire will be broken or broken. In addition, the solder joints of traditional network transformers are large, the amount of tin material is large, the production cost and labor cost are high, and the distance between the two pins of the traditional transformer is narrow after winding, which is easy to cause short circuit and cause high scrap rate The scrap rate of transformers is high, and it is also prone to the risk of hidden dangers in electrical performance.
