Preparation method of network transformer

Abstract

The invention discloses a preparation method of a network transformer. The preparation method comprises the following steps of: (1) preparing parts: preparing a network transformer base, a network transformer upper cover, a stranded wire, a main transformer magnetic ring and a common mode choke magnetic ring; (2) winding a coil: winding the stranded wire on the main transformer magnetic ring and the common mode choke magnetic ring according to a winding quality standard, and completing multi-loop ring penetrating setting; (3) fixing the coil: putting the wound coil into an accommodating grooveof the network transformer base; and (4) cutting a lead: cutting the wound coil into a lead with a set length by using a cutter. According to the preparation method of the network transformer, the stranded wire formed by twisting four strands of enameled wires is selected to wind the magnetic ring to form the coil, so that the network transformer has stronger functions; the colors of the strandsof enameled wires are different, so that wire arrangement during processing is facilitated, and the problems of lead refinement or lead breakage and the like caused by direct immersion of pins and thelead into high-temperature tin liquid are avoided.

Description

technical field [0001] The invention relates to the technical field of network transformers, in particular to a method for preparing a network transformer. Background technique [0002] The network transformer is also called a data pump or a network isolation transformer. It can not only filter the differential signal sent by the PHY with a differential-mode coupled coil coupling filter to enhance the signal, but also couple it to the other end of the connecting network cable of different levels through the conversion of the electromagnetic field. It can also isolate the different levels of different network devices connected by network cables to prevent different voltages from being transmitted through the network cables and damage the devices. In addition, the network transformer can also play a certain role in lightning protection for the devices. In network communication and trunk product lines, it is used to adjust the quality and status of communication circuits. [0...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for preparing a network transformer, so as to solve the problem that single-strand enameled wires are often used to make coils in the market today, and the performance of the produced network transformer is not strong enough to meet foreign needs, and the network transformer is being produced. During the process, it is necessary to carry out processes such as lead wire winding and tinning. However, due to the high temperature of the tin liquid in the tin furnace during immersion tinning, the risk of disconnection is likely to occur when the PIN pins are directly subjected to high-temperature tinning, which makes the network transformer qualified during production. The problem of lower production rate and higher production cost
