Network transformer and line hanging method of network transformer

Abstract

The invention discloses a network transformer. The network transformer comprises a shell base, a shell upper cover and dual rows of pins, wherein an accommodating groove is formed in the shell base and is used for accommodating a magnetic ring coil, the shell upper cover can cover the shell base, the dual rows of pins are arranged on the shell base, and a U-shaped clamping groove is formed in oneend, near to an opening of the accommodating groove, of each of dual rows of pins and is used for accommodating a lead of the magnetic ring coil. A line hanging method of the network transformer comprises the following steps of (a) placing the magnetic ring coil in the accommodating groove, allowing the lead of the magnetic ring coil to penetrate through a line through groove, and clamping the lead of the magnetic ring coil into the U-shaped clamping groove; (b) welding the lead arranged in the U-shaped clamping groove in the step (a) so that the lead is fixed in the U-shaped clamping groove and electrically communicates with the dual rows of pins; and (c) covering the shell upper cover and fixing the shell upper cover at the shell base.

Description

technical field [0001] 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 [0002] 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 d...

Problems solved by technology

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. After 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
