Network transformer as well as network module and electronic device using same

Abstract

The invention discloses a network transformer as well as a network module and an electronic device using the same. The network transformer comprises a plurality of coil groups, an insulating partition board and a shell provided with a plurality of pins, wherein the network transformer is assembled on a printed circuit board through the pins of the shell; the insulating partition board is arranged in the shell and connected with at least two side walls of the shell to form a plurality of isolation grooves; and each isolation groove is used for accommodating one of the coil groups. In the invention, the insulating partition board is arranged in the shell of the network transformer to form the plurality of isolation grooves in the shell so as to respectively isolate the coil groups in the network transformer, thereby the condition that when the network transformer suffers from lightning strike, instant high voltage can puncture the winding on one coil to penetrate through another group of coil to cause damage of network equipment is avoided. The invention improves the lighting-strike resisting effect of the network transformer, saves peripheral parts and achieves the cost advantage.

Description

technical field [0001] The present invention relates to a transformer, and in particular to a network transformer (Network Transformer). Background technique [0002] With the development of computer technology, the application of network technology is also improving day by day. Today's computers have gradually moved away from the process of stand-alone operation and entered the era of network operation. Therefore, various network modules and devices for controlling network connections are also continuously developed. [0003] Generally speaking, various computer devices communicate with computers on other networks through network modules and network cables. Figure 1a It is a schematic diagram of a typical computer device connected to a network. The computer device 101 is connected to the Internet 103 through a network cable 104a. The computer device 102 is connected to the Internet 103 through a network cable 104b. In this way, the computer device 101 and the computer d...

Problems solved by technology

As a result, when the network module is struck by lightning, the instantaneous high voltage generated on the coil group 203 may break through the insulation layer of the enameled wire and couple to another coil group, thereby causing damage to the network equipment.
