Abstract

The invention provides an insulating transformer device, a printed circuit board and a manufacturing method thereof. The device consists of an insulating transformer part and an interface part, wherein, the insulating transformer part comprises a plurality of insulating transformers, a plurality of resistors and a first capacitor; one end of each resistor is respectively connected to a coil CT end of the corresponding insulating transformer, while the other end of each resistor is connected to a PGND network through the first capacitor; and the interface part comprises a plurality of RJ45 interfaces, a plurality of sets of resistors and a second capacitor, wherein each set of resistor includes two resistors, one end of one resistor is connected to 4, 5 pins of the RJ45 interfaces corresponding to the set of the resistors, one end of the other resistor is connected with 7, 8 pins of the RJ45 interfaces corresponding to the set of the resistors, and the other ends of the two resistors are connected to the PGND network through the second capacitor. The invention can upgrade the lightning protection of the network ports with hundreds of megabytes and reduce the lightening damage to the network equipment.

Description

technical field [0001] The invention relates to the communication field, in particular to a 100M network port isolation transformer device for optimizing the lightning protection performance of the 100M network port, a printed circuit board, and a method for manufacturing the printed circuit board. Background technique [0002] With the promotion of the application of network equipment, the phenomenon of damage to network equipment caused by lightning occurs frequently, and the direct economic losses caused are becoming more and more serious. The research on improving the lightning protection capability of network ports has become more and more valuable. [0003] In the process of realizing the present invention, the inventor finds that there are following problems in the prior art: [0004] On some network devices with high-density ports, due to the dense ports, the spacing between devices in PCB (Print Circuit Board: Printed Circuit Board) design is very small, and the wir...
